A Medical Chart Audit to Assess Endocrinologist Perceptions of the Burden of Endogenous Cushing’s Syndrome

Posted on January 27, 2024 by MaryO

Abstract

Purpose

This study was undertaken to assess the unmet needs within the endogenous Cushing’s syndrome (CS) care paradigm from the endocrinologist’s perspective, including data abstracted from patient charts. The study evaluated endocrinologists’ perceptions on burden of illness and treatment rationale along with the long-term clinical burden of CS, tolerability of CS treatments, and healthcare resource utilization for CS.

Methods

Retrospective medical chart data from treated patients with a confirmed diagnosis of CS was abstracted using a cross-sectional survey to collect data from qualified endocrinologists. The survey included a case report form to capture patient medical chart data and a web-enabled questionnaire to capture practitioner-level data pertaining to endocrinologists’ perceptions of disease burden, CS treatments, and treatment attributes.

Results

Sixty-nine endocrinologists abstracted data from 273 unique medical charts of patients with CS. Mean patient age was 46.5 ± 13.4 years, with a 60:40 (female:male) gender split. The mean duration of endogenous CS amongst patients was 4.1 years. Chart data indicated that patients experienced a high burden of comorbidities and symptoms, including fatigue, weight gain, and muscle weakness despite multi-modal treatment. When evaluating treatments for CS, endocrinologists rated improvement in health-related quality of life (HRQoL) as the most important treatment attribute (mean score = 7.8; on a scale of 1 = Not at all important to 9 = Extremely important). Surgical intervention was the modality endocrinologists were most satisfied with, but they agreed that there was a significant unmet treatment need for patients with CS.

Conclusion

Endocrinologists recognized that patients with CS suffered from a debilitating condition with a high symptomatic and HRQoL burden and reported that improvement in HRQoL was the key treatment attribute influencing their treatment choices. This study highlights unmet needs for patients with CS. Patients with CS have a high rate of morbidity and comorbidity, even after treatment.

Introduction

Endogenous Cushing’s syndrome (CS) is a rare, debilitating disorder caused by chronic overproduction of cortisol [1,2,3]. CS has an estimated incidence of 0.7 to 2.4 cases per million per year, with a majority of cases (~ 70%) occurring in women [1, 4, 5]. Active CS is characterized by a variety of signs and symptoms, including muscle weakness, obesity, depression, menstrual changes, facial redness, decreased libido, hirsutism, acne, ecchymoses, hypertension, diabetes, and neurocognitive deficits [6]. Because of the diverse constellation of associated symptoms, many of which are common in the general population, CS can be challenging to diagnose and patients often seek input from multiple specialists (i.e., orthopedists, rheumatologists, gynecologists, and endocrinologists) prior to receiving a correct diagnosis [6].

Current treatment options for CS include surgery as the first line of treatment, followed by pharmacotherapies as the second line option and radiation therapy, among other treatments, as a potential third line option. Pharmacotherapies include steroidogenesis inhibitors (e.g., ketoconazole, levoketoconazole, metyrapone, osilodrostat, mitotane), glucocorticoid receptor antagonists (e.g., mifepristone), and medications that inhibit tumoral ACTH secretion (e.g., pasireotide, cabergoline) [6,7,8,9,10]. These pharmacotherapies can be administered as monotherapy or in combination.

The impact of CS on overall health-related quality of life (HRQoL) has been previously described [11]. However, studies reporting both the patient burden (via medical charts) and physician perceptions of burden are lacking, and studies examining healthcare resource utilization (HCRU) and the economic burden of CS are limited. The current study reviewed medical charts of patients with CS to characterize the overall burden of CS (including symptoms, treatments, and HCRU) as well as physician perceptions of available treatments for CS and the rationale behind associated treatment decisions.

Methods

Study design and recruitment

This quantitative, cross-sectional study was conducted to collect disease burden data pertaining to patients with CS from qualified physician respondents. All study materials were reviewed and granted exemption by a central Institutional Review Board (IRB) prior to study execution (Advarra; Columbia, MD; https://www.advarra.com/). HCPs were recruited via a physician panel through an independent recruitment partner (Toluna) and received an appropriate honorarium for their time participating in the study.

This study was fielded between May 26 and July 27, 2021, and involved the abstraction of retrospective medical chart data from patients with a confirmed diagnosis of CS by endocrinologists. The survey included a 45–60-min web-enabled questionnaire, including a case report form (CRF) component, to capture patient medical chart data and health care practitioner (HCP)-level data in order to assess perceptions of CS disease burden, treatments, and attributes associated with treatments. Considering the rarity of CS, each HCP was required to abstract information from a minimum of 2 patient charts, and a maximum of 8 patient charts.

Selection of study population

HCPs were able to participate in the study if they:

  1. 1.Were board-certified or board-eligible in endocrinology in the United States.
  2. 2.Had been in practice for more than 3 years and less than 35 years post residency.
  3. 3.Spent at least 25% of their professional time providing direct patient care.
  4. 4.Had treated or managed at least 40 unique patients (of any condition) in an average month.
  5. 5.Had managed (i.e., had an appointment with) at least 3 patients with CS in the past year.
  6. 6.Had access to confirmed CS patient chart(s) at the time of the study.

Each HCP who qualified to participate provided information via chart abstraction from the medical records of 2–8 patients with CS. The selected medical charts were from patients ≥ 21 years of age who had received a physician confirmed diagnosis of CS at least 3 months before the time of the study, and had received at least one therapy (surgical, radiological, or pharmacological) to treat their CS within the past 12 months. Patients who were diagnosed with adrenal or pituitary carcinomas were excluded.

Data analysis

The data analysis was conducted in SAS 9.4 (SAS Institute Inc., Cary, NC, USA) and Q Research Software 5.6. (Q Research Software, New York, NY). After pilot interviews and throughout the fielding, quality control checks of all the case report forms were conducted to ensure that charts with logical inconsistencies were removed from the sample. Descriptive statistics (such as means, medians, and frequencies) were used to describe the study population across various patient and physician level metrics.

Results

Endocrinologists’ demographics and practice characteristics

Endocrinologists’ demographic information and practice characteristics are presented in Table 1. A total of 69 endocrinologists were surveyed and they provided information on 273 unique patient charts. The majority of the 69 endocrinologists surveyed (53/69, 73%) were male. The mean (± SD) time in practice was 17.3 (± 7.6) years. The majority of endocrinologists (35/69, 51%) worked in urban practices and were in private practice settings (47/69, 68%) (Table 1). The sample was almost equally distributed between physicians from the northern (26%), southern (29%), eastern (25%) and western (22%) regions of the United States. The mean (± SD) estimated number of patients with endogenous CS seen in the last 6 months was 30 (± 34.4) patients.

Patient demographics

Patient demographics and clinical characteristics at the time of the survey are shown in Table 2. The majority of patients (165/273, 60%) were female with a mean (± SD) age at diagnosis of 40.2 (± 12.3) years and a mean (± SD) age at the most recent visit of 46.5 (± 13.4) years. Mean (± SD) BMI was 33.3 (± 8.3) kg/m2, with 50.5% of patients categorized as obese, 33.0% of patients categorized as overweight, 14.7% of patients categorized as normal or healthy weight, and 1.8% of patients categorized as underweight (Table 2). Most patients (167/273, 61%) had private or commercial health insurance. Patient demographics and clinical characteristics at disease diagnosis are shown in Table 2. A majority of patients (194/273, 79%) originally saw their primary care physician (PCP) prior to diagnosis and were diagnosed in a private practice setting (182/273, 67%). At the time of diagnosis, 46/273 patients (17%) had poor health, 107/273 patients (39%) had fair health, 68/273 patients (25%) had neutral health, 45/273 patients (16%) had good health, and 7/273 patients (3%) had excellent health, according to the responding physician.

Treatment of endogenous Cushing’s syndrome

The patient treatment experience at the time of the study is presented in Table 2. Of the 273 patients, 79 (28.9%) underwent surgery only, 11 patients (4.0%) underwent surgery and radiation therapy, 4 patients (1.4%) underwent radiation therapy and pharmacotherapy, 5 patients (1.8%) underwent surgery, radiation therapy, and pharmacotherapy, 85 patients (31.1%) underwent surgery and pharmacotherapy, 2 patients (< 1%) underwent radiation alone and 87 patients (31.9%) underwent pharmacotherapy alone.

Symptomatic burden of endogenous Cushing’s syndrome

At diagnosis, 34% of patients presented with 1–3 symptoms, 33% of patients presented with 4–6 symptoms, 20% of patients presented with 7–9 symptoms, 8% of patients presented with 10–12 symptoms, and 5% of patients presented with > 13 symptoms (Fig. 1). Symptoms of CS at the time of diagnosis are shown in Fig. 2. The top 10 most common symptoms of CS at the time of diagnosis (Fig. 3) included fatigue, weight gain (in the midsection and upper back), acne, muscle weakness, facial weight gain (i.e., facial roundness), decreased libido, headache, edema, emotional lability, and hirsutism. Although symptoms decreased post-treatment, a large proportion of subjects still exhibited these symptoms post-treatment (Fig. 3). The most commonly reported comorbidities observed in patients with CS at the time of CS diagnosis (i.e., those affecting ≥ 20% of patients) included obesity, hypertension, depression, diabetes, dyslipidemia, anxiety, and impaired glucose tolerance (Table 2).

Economic burden of Cushing’s syndrome

Healthcare resource utilization was assessed (Table 3). Patients required a mean (± SD) of 1 (± 1.4) hospitalization annually with a mean (± SD) length of impatient stay of 4.3 (± 3.1) days. Patients required a mean (± SD) of 0.6 (± 1.3) annual emergency room (ER) visits, and 4.3 (± 6.3) outpatient visits.

Endocrinologists’ perceptions of disease burden

Endocrinologists were asked if they agreed with a series of statements regarding their perception of CS burden and impact on a scale of 1–9, where 1 = Not at all agree and 9 = Completely agree (Fig. 4). The highest proportion of endocrinologists responded “Completely agree” with the statements “CS patients can have reduced ability to function at work or school due to their condition” (percent of endocrinologists who responded “Completely agree” = 35%), “patients with CS feel the impact of their condition every day” (30%), that “CS is a debilitating condition” (28%), “patients with CS often have impaired health-related quality of life” (28%), and “CS results in sleep disturbances that adversely impact patient’s HRQoL” (26%).

Endocrinologists’ treatment perceptions

Endocrinologists were asked for their perceptions of the most important treatment attributes on a scale of 1 to 5, where 1 = the least important and 5 = the most important (Table 4). The two most important treatment attributes included treatments that were efficacious post-surgery (mean score = 4.0) and efficacious as a combination therapy (3.7). Endocrinologists were asked to rank satisfaction with currently available treatments for CS including surgical intervention, pharmacotherapy, and radiological or other interventions on a scale of 1–9, where 1 = Not at all satisfied and 9 = Extremely satisfied (Table 5). Overall, endocrinologists reported highest satisfaction with surgical intervention with regards to initial efficacy (mean score = 7.2), durability (6.9), safety (6.3), side effects (6.2), tolerability (6.4), and patient’s overall experience (6.9). Endocrinologists also ranked pharmacotherapy higher than radiation therapy for the treatment of CS for initial efficacy (5.9 versus 5.2), safety (5.9 versus 5.4), side effects (5.3 versus 5.2), tolerability (5.7 versus 5.5), and patient’s overall experience (5.9 versus 5.4).

Endocrinologists’ attitudes toward treatments and interventions

Key factors for evaluating and selecting a CS treatment were rated on a scale of 1–9, with 1 = Not at all important and 9 = Extremely important (Fig. 5). Improving HRQoL (mean score = 7.8) was rated as the most important attribute. Similarly, improving cardiovascular complications/events (e.g., myocardial infarction, stroke, embolism) (7.6), psychiatric symptoms (e.g., depression, anxiety, mood changes) (7.6), skeletal/muscular symptoms (e.g., muscular weakness, decrease in bone mineral density, bone fractures) (7.5), and neurologic symptoms (e.g., headaches, memory, and cognitive difficulties including brain fog) (7.5) were ranked as key factors when choosing CS treatment. While factors in the survey such as “causes high rate of adrenal insufficiency” and “label contains a warning against use in CS” were ranked as less important, none of the factors listed were considered unimportant by physician respondents for choosing CS treatment.

Endocrinologists were asked if they agreed with a series of statements regarding CS treatment and intervention attitudes on a scale of 1–9, where 1 = strongly disagree and 9 = strongly agree (Table 6). The three highest scoring statements were “there is a significant clinical unmet need for patients with endogenous CS” (mean score = 6.6), “better patient support services for CS medications often leads to better patient adherence” (6.5), and “patient out of pocket cost is a significant burden for CS patients on a pharmacological therapy” (6.5). The lowest scoring statement was “patient out of pocket cost is not a significant factor when prescribing pharmacological therapy for my CS patients” (4.6).

Discussion

This study provides valuable information on the physician’s perspective of unmet needs and treatment goals for patients with CS. Endocrinologists in our sample strongly agreed that patients with CS suffered from a debilitating daily condition with a high HRQoL burden. Endocrinologists also strongly agreed with the view that “there is a significant clinical unmet need for patients with endogenous CS” and ranked prescribing treatments to improve HRQoL, cardiovascular events, depression, and anxiety as key factors influencing treatment decisions. The importance providers place on the availability of post-surgery treatment options reflects the inability of many patients with CS to achieve complete post-surgical symptom resolution and suggests all symptoms in patients with CS are not currently addressed with available treatments.

Multiple treatment modalities were utilized by endocrinologists in the care of patients with CS, including surgery, pharmacotherapy, and/or radiation therapy. Improvement in HRQoL was the key treatment attribute influencing CS treatment choices, followed by the goal of reducing cardiovascular complications, and decreasing psychiatric symptoms. However, the prevalence of comorbidities after CS treatment as well as endocrinologists’ perceptions and attitudes regarding an unmet need for CS treatments and ongoing disease burden showed that few therapies are able to improve patients’ ongoing disease burden. New CS treatments are needed that have long-term efficacy, fewer side effects, and effective reimbursement.

Patients with CS have a high symptomatic disease burden at diagnosis. This study and others have demonstrated that many of these signs and symptoms (e.g., hypertension, obesity, and depression) persist even after receiving treatment aimed at normalizing cortisol levels [12,13,14,15]. Results from the present study show that many patients continue to experience fatigue, weight gain, muscle weakness, and emotional lability even after treatment, indicating an unmet need for CS treatments that can effectively manage these persistent symptoms. The persistence of symptoms after treatment for CS is likely multifactorial, and may, at least in part, be due to complications of prolonged hypercortisolism, given diagnostic and treatment delays; however, the ability to predict which patients will continue to experience persistent symptoms after treatment is challenging [14, 16, 17]. Additionally, the effects of inadequate cortisol control, symptoms due to glucocorticoid withdrawal, and side effects from medications taken to address comorbidities may contribute to persistent symptoms after treatment for CS. Although there are currently established reference values and treatment guidelines used to stratify patients, there are no current clear guidelines on management of ongoing symptoms after cortisol levels have been addressed [18]. Additionally, the present study indicated that only 32% of patients were diagnosed at the first presentation of their CS symptoms, underscoring the importance of increasing awareness of CS and its presentation among PCPs to expedite diagnosis and treatment.

The economic burden of illness from CS includes both the direct impact on HCRU, and the indirect impact on the patient due to loss of work productivity. The present study determined that the mean (± SD) annual number of hospitalization among patients with CS was 1 (± 1.4) day with an average length of inpatient stay of 4.3 days, similar in duration to the mean length of stay for all hospitalizations in the US [19]. However, the average number of outpatient visits among patients with CS was 4.3 visits per year, slightly lower than described in a recent study of patients with CS [11], but almost twice the rate of the average American, indicating a substantial direct cost burden [20]. Patients’ reduced ability to function at work or at school could limit their full economic potential, not only for themselves, but for family members and caregivers, indicating an indirect economic cost.

The degree of concordance between patients’ chart data and the perceptions of providers regarding disease symptoms is an important issue raised, but not directly addressed, by this study. Although endocrinologists agreed that there was a high HRQoL burden attributable to CS, this study did not analyze patients’ perceptions of HRQoL burden of CS. Discordance between patients’ perceptions and the perceptions of their healthcare providers, as well as the tendency of providers to perceive disease burden as less impactful or severe than is perceived by patients, has been reported in other medical conditions such as acromegaly, rheumatoid arthritis and chronic pain. The result of this is often worse medical outcomes for patients with rheumatoid arthritis or worse pain and functioning in patients with chronic pain [21,22,23,24]. Further study is necessary to analyze the concordance between the perceptions of physicians and patients with CS.

A recent cross-sectional web-enabled survey burden of illness study and a recent systemic literature review [11, 25, 26], conducted by the authors of this study, elucidated both the burden of CS as well as unmet needs in the healthcare system for patients with CS. The results of the current study corroborate the findings of both of these studies, confirming that patients experience a substantial and complex burden of cumulative CS symptoms that impacts their HRQoL. Similar to prior studies, the current results also demonstrate that although symptoms improve with treatment, some symptoms such as weight gain, pain, and anxiety persist even after treatment interventions, including surgery, pharmacotherapy, and radiation therapy. Patients with CS have previously been shown to have worse HRQoL scores compared to healthy counterparts [26], underscoring the long-term effects of CS despite treatment. This study and others have demonstrated that current therapies do not completely mitigate this HRQoL burden and indicate an unmet need among many patients with CS for additional treatments to control symptoms after cortisol level normalization.

Study limitations

During the time in which this study was conducted, additional CS treatments could have been approved, potentially changing the treatment landscape, and thereby altering the proportion of patients that continued to have symptoms after treatment (Fig. 3) or the proportion of patients with a particular comorbidity after treatment. Physician response may have been subject to recall bias; although this may have been mitigated by the use of patient chart data the possibility that details were omitted at the time of patient visits exists. Additionally, when physicians were asked about working in a Center of Excellence, the term was not explicitly defined which may have led to varying interpretations by respondents. Due to the nature of the method used (i.e., a survey given to endocrinologists treating patients at the present time), we have limited historical chart data on the entire medical journey of each patient and all important medical events may not have been captured. For example, treatments administered to patients prior to this study (i.e., those administered by previous doctors or from a different hospital) may not be present in the patients’ charts and were not captured by our survey. Additionally, we did not capture biochemical data to make definitive statements on disease status based on patient cortisol levels. Updated guidelines on cortisol levels indicative of disease severity have recently been issued by the Pituitary Society [18], and a shift toward standardized clinical guidelines may help physicians provide timely and appropriate treatment for patients with CS. Future patient-centered research in CS should focus on identifying biomarkers associated with persistent symptoms after initial treatment, which could influence the development of guidelines for managing ongoing symptoms as current treatments are focused on cortisol management. The cohort of patients with CS included in our study is also not representative of the full spectrum of patients with CS as they were required to have received at least one pharmacological therapy to be eligible for the study. This requirement was added to our eligibility criteria as the aim of our study was to evaluate the burden of illness faced by patients with Cushing’s Syndrome, post-treatment, in the real world. Future studies evaluating concordance between patient chart data and physician perceptions of CS symptoms are also likely to be of interest. Finally, patient symptoms in this study could potentially have been masked due to the use of over-the-counter medications or other prescription treatments not fully captured in charts.

Conclusion

Patients with CS continue to experience symptoms such as fatigue, weight gain, muscle weakness, and emotional instability even after seeking and receiving treatment, indicating an unmet need for treatments that control symptoms. Future research is needed to develop a treatment paradigm that alleviates disease burden in patients with CS and that results in long-term disease control with a favorable side effect profile.

Adults with Cushing’s Syndrome Report High Burden Of Illness, Despite Ongoing Treatment

Posted on September 4, 2023 by MaryO

Key takeaways:

  • Cushing’s syndrome symptoms moderately impact quality of life for adults with the condition.
  • Weight gain, muscle fatigue and menstrual changes decline in severity from diagnosis to follow-up.

Adults with endogenous Cushing’s syndrome reported that the condition moderately affects their quality of life and causes them to have symptoms about 16 days in a given month, according to findings published in Pituitary.

“Our study aimed to evaluate the ongoing burden of Cushing’s syndrome in order to identify areas of unmet need,” Eliza B. Geer, MD, medical director of the Multidisciplinary Pituitary and Skull Base Tumor Center and associate attending of endocrinology and neurosurgery at Memorial Sloan Kettering Cancer Center, told Healio. “We found that patients with treated Cushing’s continue to experience ongoing symptoms more than half of the days in a given month, miss about 25 workdays per year and need twice the average number of outpatient visits per year, indicating a significant impact on daily function and work productivity. Some of these symptoms, like fatigue and pain, have not been well studied in Cushing’s patients, and need more attention.”

Geer and colleagues administered a cross-sectional survey to 55 adults aged 21 years and older who had been diagnosed with Cushing’s syndrome at least 6 months before the survey and were receiving at least one pharmacologic therapy for their disease (85% women; mean age, 43.4 years). The survey was conducted online from June to August 2021. Five patient-reported outcome scales were included. The CushingQoL was used to analyze quality of life, a visual analog scale was included to assess pain, the Brief Fatigue Inventory was used to measure fatigue, the Sleep Disturbance v1.0 scale assessed perceptions of sleep and the PROMIS Short Form Anxiety v1.0-8a scale was used to measure fear, anxious misery, hyperarousal and somatic symptoms related to arousal. Participants self-reported the impact of Cushing’s syndrome on daily life and their physician’s level of awareness of Cushing’s syndrome.

Some symptoms decline in severity over time

Of the study group, 81% had pituitary or adrenal tumors, and 20% had ectopic adrenocorticotropic hormone-producing tumors; 80% of participants underwent surgery to treat their Cushing’s syndrome.

The frequency of reported symptoms did not change from Cushing’s syndrome diagnosis to the time of the survey. The most frequently reported symptoms were weight gain, muscle fatigue and weakness and anxiety.

Participants reported a decline in symptom severity for weight gain, muscle fatigue and weakness and menstrual changes from diagnosis to the survey. Though symptom severity declined, none of the three symptoms were entirely eliminated. Adults did not report declines in severity for other symptoms. Hirsutism and anxiety were reported by few participants, but were consistently scored high in severity among those who reported it. There were no changes in patient satisfaction with medications from their first appointment to the time of the survey.

“It was surprising that anxiety and pain did not improve with treatment,” Geer said. “A quarter of patients at baseline reported anxiety and this percentage was exactly the same after treatment. Same for pain — nearly a quarter of patients reported pain despite treatment. While the presence of anxiety has been well-documented in Cushing’s patients, pain has not, and needs further study.”

Nearly half of primary care providers unable to diagnose Cushing’s syndrome

All participants reported having at least one challenge with being diagnosed with Cushing’s syndrome. Of the respondents, 49% said their primary care provider was unable to diagnose their Cushing’s syndrome and 33% initially received the wrong diagnosis. Physicians referred 49% of participants to a specialist, and 39% of adults said their doctor lacked knowledge or understanding of their condition.

The study group had a moderate level of quality of life impairment as assessed through the CushingQoL scale. The mean pain score was 3.6 of a possible 10, indicating low levels of pain. Moderate to severe levels of fatigue were reported by 69% of participants. Self-reported sleep and anxiety scores were similar to what is observed in the general population.

Participants said sexual activity, self-confidence and life satisfaction were most impacted by a Cushing’s syndrome diagnosis. Adults experienced symptoms a mean 16 days in a typical month and saw their outpatient physician an average of six times per year. Those who were employed said they miss 2 days of work per month, or about 25 days per year, due to Cushing’s syndrome.

“Longitudinal assessment of clinically relevant patient-reported outcomes based on validated measures and coupled with biochemical and treatment data is needed in a large cohort of Cushing’s patients,” Geer said. “This will allow us to identify clinically meaningful changes in symptom burden within each patient, as well as predictors of outcomes — which patients improve on which symptoms, and which patients do not feel better despite biochemical normalization. We need to improve our ability to help our patients feel better, not just achieve normal cortisol levels.”

Cushing’s Disease Associated With Partially Empty Sella Turcica Syndrome

Posted on June 28, 2023 by MaryO

Abstract

The association between empty sella turcica (EST) syndrome and Cushing’s disease has been rarely reported. It is plausible to hypothesize that EST syndrome in association with Cushing’s disease can be attributed to intracranial hypertension. In this case report, we present a 47-year-old male patient who presented with weight loss, fatigue, easy bruising, acanthosis nigricans, and skin creases hyperpigmentation. Investigations revealed hypokalemia and confirmed the diagnosis of Cushing’s disease. Magnetic resonance imaging (MRI) brain showed a partial EST syndrome and a new pituitary nodule as compared with previous brain imaging. Transsphenoidal surgery was pursued and was complicated by cerebrospinal fluid leakage. This case reflects the rare association of EST syndrome and Cushing’s disease, suggesting the increased risk of postoperative complications in this setting and the diagnostic challenge that EST syndrome imposes. We review the literature for a possible mechanism of this association.

Introduction

Cushing’s disease is commonly caused by an adrenocorticotropic hormone (ACTH)-producing pituitary adenoma, which can be very challenging to be seen on brain magnetic resonance imaging (MRI) [1]. Empty sella turcica (EST) syndrome is a radiological diagnosis of apparently empty turcica secondary to outpouching of the arachnoid mater into the turcica, which can be attributed to intracranial hypertension (ICHTN). This can make the visual diagnosis of pituitary adenoma even more challenging in clinical practice. ICHTN has been also associated with Cushing’s disease and might explain this infrequent association between EST and Cushing’s disease [1]. EST syndrome can be either partial or complete, primary or secondary and has been seen infrequently with Cushing’s disease. In this setting, not only that it is likely to obscure an underlying pituitary lesion, but also it does contribute to the risk of postoperative complications [2].

Case Presentation

A 47-year-old male presented to the emergency department (ED) with slowly progressive generalized limb muscle weakness affecting both distal and proximal muscles over a few weeks and gait instability for three days prior to presentation. He also reported unintentional 40 pounds weight loss over the previous four months. Past medical history was significant for type II diabetes mellitus, hypothyroidism, hypertension, and dyslipidemia. In the ED, vital signs included a blood pressure of 140/90 mmHg, a heart rate of 66 beats per minute, a respiratory rate of 16 cycles per minute, and SpO2 of 97% on room air. Body mass index has decreased to 22 kg/m2 from a baseline of 26 kg/m2 one month prior. On the physical exam, he exhibited cachexia, easy bruising, acanthosis nigricans, and hyperpigmentation of skin creases. All other systems were negative. Complete metabolic panel and complete blood count were obtained showing hyperglycemia of 311 mg/dl, see Table 1. Further lab evaluation showed elevated salivary cortisol at 2.96 microgram/dl (reference range 0.094-1.551 mcg/dl), elevated 24-hour urinary free cortisol at 156 mcg/24 hour (reference 10-100 mcg/24h), positive overnight dexamethasone suppression test with serum cortisol at 2.8 mcg/dl (reference more than 2 mcg/dl), negative anti-adrenal antibodies, normal aldosterone, and elevated dehydroepiandrostenedione at 401 mcg/dl (reference 32-240 mcg/dl), with lack of suppression of the ACTH level at 35.1 pg/ml (reference 10-60 pg/ml). This confirmed the diagnosis of Cushing’s disease.

Computed tomography (CT) scan of the head was unremarkable. CT scan of the chest was also unremarkable. CT scan of abdomen and pelvis showed no adrenal mass. Ultrasound of the kidneys was unremarkable. Pituitary MRI brain protocol for adenoma showed a partial EST, shortening within neurohypophysis and a new 10 x 8 x 4 mm nodule along the floor of pituitary sella as compared to MRI four years ago (Figure 1).

The diagnosis of Cushing’s disease was confirmed, and the patient underwent trans-sphenoidal resection of pituitary adenoma. Histological examination showed positive CAM 5.2, positive chromogranin, and ACTH immunostains. The patient presented to the ED five days after discharge home. He stated that he noticed drainage from the nose that transitioned from bloody to clear fluid and has been increasing in quantity for two days with associated intermittent headaches since the surgery. He was afebrile with stable vital signs. No signs of infection were noted on basic labs. These were significant only for mild asymptomatic hyponatremia of 131 mmol/L and hypokalemia of 3.3 mmol/L. The patient was diagnosed with cerebrospinal fluid (CSF) leakage and had a lumbar drain trial. The trial was unsuccessful after several days, and the patient underwent a transnasal endoscopic repair of CSF rhinorrhea using nasoseptal flaps. At an outpatient follow-up one month and three months after the surgery, prior lab abnormalities including hypokalemia, hyponatremia, and hyperglycemia resolved. No further evidence of CSF leakage was appreciated, and he remained asymptomatic.

Discussion

EST syndrome is characterized by herniation of the subarachnoid space into the intrasellar space with compression of the pituitary gland into the posteroinferior wall [3]. This is likely to obscure the presence of underlying pituitary mass. The incidence of EST syndrome in the general population is estimated at 20%. The association between EST syndrome and Cushing’s disease has been reported infrequently. A retrospective study of 68 patients with Cushing’s disease found that 16% of these have EST syndrome [3].

Cushing’s disease usually results from pituitary adenomas secreting ACTH, and even the smallest microadenomas can produce a systemic disease. These microadenomas can be very difficult to recognize on brain MRI [4]. This is complicated in EST syndrome and even further with the possibility of ectopic ACTH production. A retrospective study of 197 patients diagnosed with Cushing’s disease concluded that EST syndrome is associated with higher prevalence of MRI-negative Cushing’s disease. This was attributed to ICHTN and pituitary gland compression [1]. Although surgery is curative in 70-90% of cases, EST syndrome was found to have higher risk of postoperative complications among those with Cushing’s disease including diabetes insipidus, hypopituitarism, and CSF leakage [3]. This is usually because in the case of MRI-negative Cushing’s disease with total EST syndrome, empiric surgical exploration is sought after inferior petrosal sampling confirms the pituitary origin of excess ACTH, and postoperative remission indicates adequate tumor resection [2]. This entails a higher chance of uncertainty and injury to healthy pituitary tissue.

EST syndrome can be either primarily due to defects in the sellar diaphragm or anatomical variant or secondary to ICHTN. EST syndrome has been reported in association with many conditions associated with elevated intracranial pressure including tumors, thrombosis, meningitis, hydrocephalus, and Arnold-Chiari malformation [5]. Reversal of EST syndrome has been reported in those with idiopathic ICHTN with therapy by acetazolamide, ventriculoperitoneal shunt, and lumbar puncture [6,7]. A study has shown correlation between CSF circulation impairment or blockage and EST syndrome [8]. The incidence of EST syndrome in association with symptomatic intracranial hypertension is variable and ranges from 2.5% for total EST syndrome to 94% for partial EST syndrome [9]. Impaired CSF circulation and dynamics have been reported in 77% of patients with EST syndrome [10]. In addition to intracranial hypertension, EST syndrome has also been described in association with obesity, meningioma, pediatric nevoid basal cell carcinoma, therapy for growth hormone deficiency and even in healthy individuals [9]. Lack of symptoms of intracranial hypertension in this patient does not rule it out as intracranial hypertension in EST syndrome represents a spectrum that ranges from asymptomatic, milder intracranial hypertension to symptomatic intracranial hypertension with headache, visual disturbance, and papilledema [10]. This explains the fact that only 8-14% of EST syndrome progress to symptomatic ICHTN, while symptomatic ICHTN has been associated with EST syndrome in 94% of cases.

ICHTN has been seen in association with disturbance of the hypothalamic-pituitary-adrenal axis. This has been reported after surgical and medical treatment of Cushing’s disease, withdrawal of long-term steroid therapy, initial presentation of Addison’s disease, or relative glucocorticoids deficiency [11]. Cortisol excess increases CSF production and reduces its absorption, hence increasing intracranial pressure [12]. Another possible mechanism is the expression of both mineralocorticoid responsive epithelial sodium channel receptors on the basolateral membrane of the CSF producing epithelial cells of the choroid plexus as well as the expression of 11-beta hydroxysteroid dehydrogenase type 1 enzyme, which is a bidirectional enzyme that mainly functions to convert the inactive cortisone to active cortisol. These mechanisms play a role in maintaining the balance between CSF production and absorption [13,14].

In this case, the patient presented some clinical findings that are rarely associated with Cushing’s disease, combined with a radiological feature that masked the true diagnosis. Our patient presented with significant weight loss, rather than central obesity, which is normally associated with Cushing’s disease. Although possible, the increase in ACTH due to Cushing’s disease is not sufficient to cause hyperpigmentation, which is a classical finding of Addison’s disease, where the entire adrenal cortex is usually affected due to an autoimmune destruction; however, the zona glomerulosa of the adrenal cortex produces aldosterone and its deficiency would lead to hyperkalemia [15]. Our patient presented with both hyperpigmentation and hypokalemia.

Conclusions

EST syndrome is an uncommon radiological finding of apparently EST that has been reported in association with ICHTN. The latter has also been seen in association with Cushing’s disease/syndrome. This is likely to result from glucocorticoid excess-induced change in CSF flow dynamics. EST has been infrequently described in association with Cushing’s disease. This association has a clinical implication as it is likely to obscure the visualization of pituitary lesions responsible for Cushing’s disease, contribute to diagnostic uncertainty, and increase the risk of healthy pituitary tissue injury and the risk of postoperative complications including CSF leakage.

7 Things Your Hair Reveals About Your Health

Posted on January 20, 2022 by MaryO

Your hair can tell you and your doctor if you are stressed, have a nutritional deficiency, thyroid problem, or other health issues. Here are seven key things to look for in your hair.

You probably think about your hair every day: worrying about a bad day, enjoying a good blow-dry, or wondering if you have to try the new style you noticed in your favorite celebrity. But you may be missing the clues your hair reveals about your health. Research shows that changes in the look, texture, or thickness of your hair can be signs of underlying health issues. Here’s how to tell if your hair changes are due to a health condition, genetics, stress, or a nutritional deficiency.

1 Stress (and genes) can cause you to turn gray

Anyone who has observed the hairstyle changes of a President of the Republic from one campaign to another has noticed that stress seems to cause hair to turn white. A mouse study published in the journal Nature suggests that chronic stress may actually contribute to white hair by causing DNA damage and reducing the number of pigment-producing cells in hair follicles. Stress can also lead to hair loss.

Another type of stress, known as oxidative stress, can also play a role in white hair. Oxidative stress can affect pigment-producing cells. Turning gray is actually a completely natural part of aging because hair follicles produce less color as you age. Your genes also play a role in when your hair turns gray. Ask your parents how old they were when they first saw the signs of silvering, and you might do the same. In fact, a study published in March 2016 in the journal Nature Communications was the first to identify the gene responsible for white hair.

2 brittle hair could be a sign of Cushing’s syndrome

Brittle hair is one of the symptoms of Cushing’s syndrome, which is a rare condition caused by excess cortisol, the main hormone body stress. But, there are many other, more obvious symptoms of Cushing’s syndrome, including high blood pressure, fatigue, and back pain. Treatment for Cushing’s syndrome may involve changing the dose of medication that may be causing the condition, such as glucocorticoids, which are steroids used to treat inflammation caused by various diseases.

3 Thinning hair may be a sign of thyroid disease

People with hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormones, may notice increased hair loss and change in hair appearance. About 4.6% of the population aged 12 years and older have hypothyroidism, although most cases are mild. Hypothyroidism can lead to thinning hair and other symptoms, such as fatigue, intolerance to cold, joint pain, muscle aches, puffy face and weight gain. A thyroid stimulating hormone (TSH) test can diagnose the condition, and treatment involves taking thyroid medication.

In addition to thinning hair, some thyroid disorders put you at risk for risk of autoimmune hair loss called alopecia areata. This type of hair loss causes round patches of sudden hair loss and is caused by the immune system attacking the hair follicles.

4 Hair loss can be a sign of anemia

If you suddenly notice a lot more hair in your hairbrush or on the floor of your shower, it may be a sign that your body has low iron stores, or anemia , and may warrant testing. This is another blood test we do when you complain of hair changes. Vegetarians or women with heavy periods increase their risk that hair changes are due to iron deficiency.

It is unclear why iron deficiency can lead to hair loss. hair, but iron is essential for many biological and chemical reactions, perhaps including hair growth. Hair loss can also occur (temporarily) with sudden changes in estrogen levels and is often noticed after pregnancy or stopping birth control pills.

5 The loss of hair could indicate protein deficiency

Protein is essential for hair health and growth (a lack of protein has been linked to hair thinning and hair loss ). Protein deficiency is not a problem for most people. Most adults need 0.8 grams of protein per kilogram of body weight. Good sources of protein include low-fat Greek yogurt, chickpeas, and chicken breast. People who have gastrointestinal difficulties or who have just had gastric bypass surgery may have problems digesting protein. These special situations will need to be managed with the help of your doctor. But most cases of thinning hair, even in women, are probably due to genetics.

6 White or yellow flakes can mean you have dandruff

Yellow or white flakes in your hair, on your shoulders and even in your eyebrows are a sign of dandruff, a chronic scalp condition. Dandruff is usually not a sign of a health problem and can be treated with specialized over-the-counter or prescription shampoos.

One of the most common causes of dandruff is a medical condition called seborrheic dermatitis. People with seborrheic dermatitis have red, oily skin covered in white or yellow scales. A yeast-like fungus called malassezia can also irritate the scalp. Insufficient shampoo, sensitivity to hair care products, and dry skin can also cause dandruff. (Dandruff is usually more severe in the winter, when indoor heating can make skin drier).

7 Damaged hair can mask other health issues

Although hair can reveal your condition, women more often complain about the damage caused by hair coloring and heat treatment. Excessive heat, from daily use of a flat iron or blow-drying, can certainly damage your hair, making it dry, brittle and difficult to maintain. Best not to use more than one hot tool per day (occasional double heat treatment is okay, but not daily). When applying heat to your hair, always use products with protective ingredients. Serums and shine drops tend to have hair-preserving qualities when using direct and indirect heat.

Adrenal Fatigue: Faux Diagnosis?

Posted on November 30, 2021 by MaryO

This article is based on reporting that features expert sources.

U.S. News & World Report

Adrenal Fatigue: Is It Real?

You may have heard of so-called ‘adrenal fatigue,’ supposedly caused by ongoing emotional stress. Or you might have come across adrenal support supplements sold online to treat it. But if someone suggests you have the controversial, unproven condition, seek a second opinion, experts say. And if someone tries to sell you dietary supplements or other treatments for adrenal fatigue, be safe and save your money.

Physicians tend to talk about ‘reaching’ or ‘making’ a medical diagnosis. However, when it comes to adrenal fatigue, endocrinologists – doctors who specialize in diseases involving hormone-secreting glands like the adrenals – sometimes use language such as ‘perpetrating a diagnosis,’ ‘misdiagnosis,’ ‘made-up diagnosis,’ ‘a fallacy’ and ‘nonsense.’

About 20 years ago, the term “adrenal fatigue” was coined by Dr. James Wilson, a chiropractor. Since then, certain practitioners and marketers have promoted the notion that chronic stress somehow slows or shuts down the adrenal glands, causing excessive fatigue.

“The phenomenon emerged from the world of integrative medicine and naturopathic medicine,” says Dr. James Findling, a professor of medicine and director of the Community Endocrinology Center and Clinics at the Medical College of Wisconsin. “It has no scientific basis, and there’s no merit to it as a clinical diagnosis.”

An online search of medical billing code sets in the latest version of the International Classification of Diseases, or the ICD-10, does not yield a diagnostic code for ‘adrenal fatigue’ among the 331 diagnoses related either to fatigue or adrenal conditions or procedures.

In a March 2020 position statement, the American Association of Clinical Endocrinologists and American College of Endocrinology addressed the use of adrenal supplements “to treat common nonspecific symptoms due to ‘adrenal fatigue,’ an entity that has not been recognized as a legitimate diagnosis.”

The position statement warned of known and unknown health risks of off-label use and misuse of hormones and supplements in patients without an established endocrine diagnosis, as well as unnecessary costs to patients and the overall health care system.

Study after study has refuted the legitimacy of adrenal fatigue as a medical diagnosis. An August 2016 systematic review combined and analyzed data from 58 studies on adrenal fatigue including more than 10,000 participants. The conclusion in a nutshell: “Adrenal fatigue does not exist,” according to review authors in the journal BMC Endocrine Disorders.

Adrenal Action

You have two adrenal glands in your body. These small triangular glands, one on top of each kidney, produce essential hormones such as aldosterone, cortisol and male sex hormones such as DHEA and testosterone.

Cortisol helps regulate metabolism: How your body uses fat, protein and carbohydrates from food, and cortisol increases blood sugar as needed. It also plays a role in controlling blood pressure, preventing inflammation and regulating your sleep/wake cycle.

As your body responds to stress, cortisol increases. This response starts with signals between two sections in the brain: The hypothalamus and the pituitary gland, which act together to release a hormone that stimulates the adrenal glands to make cortisol. This interactive unit is called the hypothalamic pituitary adrenal axis.

While some health conditions really do affect the body’s cortisol-making ability, adrenal fatigue isn’t among them.

“There’s no evidence to support that adrenal fatigue is an actual medical condition,” says Dr. Mary Vouyiouklis Kellis, a staff endocrinologist at Cleveland Clinic. “There’s no stress connection in the sense that someone’s adrenal glands will all of a sudden just stop producing cortisol because they’re so inundated with emotional stress.”

If anything, adrenal glands are workhorses that rise to the occasion when chronic stress occurs. “The last thing in the body that’s going to fatigue are your adrenal glands,” says Dr. William F. Young Jr., an endocrinology clinical professor and professor of medicine in the Mayo Clinic College of Medicine at Mayo Clinic in Rochester, Minnesota. “Adrenal glands are built for stress – that’s what they do. Adrenal glands don’t fatigue. This is made up – it’s a fallacy.”

The idea of adrenal glands crumbling under stress is “ridiculous,” Findling agrees. “In reality, if you take a person and subject them to chronic stress, the adrenal glands don’t shut down at all,” Findling says. “They keep making cortisol – it’s a stress hormone. In fact, the adrenal glands are just like the Energizer Bunny – they just keep going. They don’t stop.”

Home cortisol tests that allow consumers to check their own levels can be misleading, Findling says. “Some providers who make this (adrenal fatigue) diagnosis, provide patients with testing equipment for doing saliva cortisol levels throughout the day,” he says. “And then, regardless of what the results are, they perpetrate this diagnosis of adrenal fatigue.”

Saliva cortisol is a legitimate test that’s frequently used in diagnosing Cushing’s syndrome, or overactive adrenal glands, Findling notes. However, he says, a practitioner pursuing an adrenal fatigue diagnosis could game the system. “What they do is: They shape a very narrow normal range, so narrow, in fact, that no normal human subject could have all their saliva cortisol (levels) within that range throughout the course of the day,” he says. “Then they convince the poor patients that they have adrenal fatigue phenomena and put them on some kind of adrenal support.”

Loaded Supplements

How do you know what you’re actually getting if you buy a dietary supplement marketed for adrenal fatigue or ‘adrenal support’ use? To find out, researchers purchased 12 such supplements over the counter in the U.S.

Laboratory tests revealed that all supplements contained a small amount of thyroid hormone and most contained at least one steroid hormone, according to the study published in the March 2018 issue of Mayo Clinic Proceedings. “These results may highlight potential risks for hidden ingredients in unregulated supplements,” the authors concluded.

Supplements containing thyroid hormones or steroids can interact with a patient’s prescribed medications or have other side effects.

“Some people just assume they have adrenal fatigue because they looked it up online when they felt tired and they ultimately buy these over-the-counter supplements that can be very dangerous at times,” Vouyiouklis Kellis says. “Some of them contain animal (ingredients), like bovine adrenal extract. That can suppress the pituitary axis. So, as a result, your body stops making its own cortisol or starts making less of it, and as a result, you can actually worsen the condition rather than make it better.”

Any form of steroid from outside the body, whether a prescription drug like prednisone or extract from cows’ adrenal glands, “can shut off the pituitary,” Vouyiouklis Kellis explains. “Because it’s signaling to the pituitary like: Hey, you don’t need to stimulate the adrenals to make cortisol, because this patient is taking it already. So, as a result, the body ultimately doesn’t produce as much. And, so, if you rapidly withdraw that steroid or just all of a sudden decide not to take it anymore, then you can have this acute response of low cortisol.”

Some adrenal support products, such as herbal-only supplements, may be harmless. However, they’re unlikely to relieve chronic fatigue.

Fatigue: No Easy Answers

If you’re suffering from ongoing fatigue, it’s frustrating. And you’re not alone. “I have fatigue,” Young Jr. says. “Go to the lobby any given day and say, ‘Raise your hand if you have fatigue.’ Most of the people are going to raise their hands. It’s a common human symptom and people would like an easy answer for it. Usually there’s not an easy answer. I think ‘adrenal fatigue’ is attractive because it’s like: Aha, here’s the answer.”

There aren’t that many causes of endocrine-related fatigue, Young Jr. notes. “Hypothyroidism – when the thyroid gland is not working – is one.” Addison’s disease, or adrenal insufficiency, can also lead to fatigue among a variety of other symptoms. Established adrenal conditions – like adrenal insufficiency – need to be treated.

“In adrenal insufficiency, there is an intrinsic problem in the adrenal gland’s inability to produce cortisol,” Vouyiouklis Kellis explains. “That can either be a primary problem in the adrenal gland or an issue with the pituitary gland not being able to stimulate the adrenal to make cortisol.”

Issues can arise even with necessary medications. “For example, very commonly, people are put on steroids for various reasons: allergies, ear, nose and throat problems,” Vouyiouklis Kellis says. “And with the withdrawal of the steroids, they can ultimately have adrenal insufficiency, or decrease in cortisol.”

Opioid medications for pain also result in adrenal sufficiency, Vouyiouklis Kellis says, adding that this particular side effect is rarely discussed. People with a history of autoimmune disease can also be at higher risk for adrenal insufficiency.

Common symptoms of adrenal insufficiency include:

  • Fatigue.
  • Weight loss.
  • Decreased appetite.
  • Salt cravings.
  • Low blood pressure.
  • Abdominal pain.
  • Nausea, vomiting or diarrhea.
  • Muscle weakness.
  • Hyperpigmentation (darkening of the skin).
  • Irritability.

Medical tests for adrenal insufficiency start with blood cortisol levels, and tests for the ACTH hormone that stimulates the pituitary gland.

“If the person does not have adrenal insufficiency and they’re still fatigued, it’s important to get to the bottom of it,” Vouyiouklis Kellis says. Untreated sleep apnea often turns out to be the actual cause, she notes.

“It’s very important to tease out what’s going on,” Vouyiouklis Kellis emphasizes. “It can be multifactorial – multiple things contributing to the patient’s feeling of fatigue.” The blood condition anemia – a lack of healthy red blood cells – is another potential cause.

“If you are fatigued, do not treat yourself,” Vouyiouklis Kellis says. “Please seek a physician or a primary care provider for evaluation, because you don’t want to go misdiagnosed or undiagnosed. It’s very important to rule out actual causes that would be contributing to symptoms rather than ordering supplements online or seeking an alternative route like self-treating rather than being evaluated first.”
