Curative Treatment on Hyperglycemia in Cushing Syndrome

Posted on December 28, 2021 by MaryO

A retrospective analysis of data from more than 170 patients with Cushing syndrome and hyperglycemia provides insight into the effects of curative treatment on hyperglycemia among these patients.

An analysis of retrospective data from a 20-year period details the impact of curative treatment on hyperglycemia among patients with Cushing syndrome.

Led by a team of investigators from the Mayo Clinic in Rochester, MN, the study examined a cohort of 174 adult patients with Cushing Syndrome and determined 2-in-3 patients with hyperglycemia experienced resolution or improvement of hyperglycemia after a curative procedure.

“This is the first study to analyze the quantitative changes based on the time from the curative surgery, to assess the changes in the intensity of hyperglycemia therapy and identify predictors for hyperglycemia improvement,” wrote investigators.

A team led by Irina Bancos, MD, endocrinologist at the Mayo Clinic Rochester, designed the current study with an interest in examining the impact of curative procedures on hyperglycemia and its management in patients with Cushing syndrome from electronic medical record data of patients treated at a referral center from 2000-2019. The primary purpose of the study was to assess the impact of curative procedures on extent of hyperglycemia and the secondary aim was to investigators how baseline factors might influence improvement of hyperglycemia at follow-up.

For inclusion in the analysis, patients needed to be at least 18 years of age, diagnosed with Cushing syndrome, and have hyperglycemia treated with a curative procedure from January 1, 2000-November 1, 2019. For the purpose of analysis, Cushing syndrome was diagnosed based on clinical evaluation by an endocrinologist and diagnosed according to the most recent guidelines. Hyperglycemia was defined according to American Diabetes Association guidelines.

The primary outcome of interest for the study was the resolution of hyperglycemia following resolution of Cushing syndrome. For the purpose of analysis, resolution was defined as absence of hyperglycemia without the need for antihyperglycemic therapy. Secondary outcomes of interest included changes in HbA1c, and the intensity of hyperglycemia management.

Overall, 174 patients were identified for inclusion in the study. This cohort had a median age of diagnosis of 51 (range, 16-82) years and 73% (n=127) were women. When assessing subtype of Cushing syndrome, the most common form was pituitary Cushing syndrome (60.9%), followed by ectopic (14.4%), and adrenal (24.7%). The median baseline HbA1c was 6.9% (range, 4.9-13.1), 24% of patients were not on any therapy for hyperglycemia, 52% were on oral medications, and 37% were on insulin (mean daily units, 58; range, 10-360).

When assessing differences between subtypes, results indicated those with pituitary Cushing syndrome were younger at the time of surgery (P=.0009), and included more women (P=.0023), and reported a longer duration of symptoms prior to diagnosis. Investigators noted patients with pituitary Cushing syndrome also had the highest clinical severity score (P <.0001), but patients with ectopic Cushing syndrome had the highest biochemical severity score (P <.0001).

Following Cushing syndrome remission and at the end of follow-up, which occurred at a median of 10.5 months, 21% of patients demonstrated resolution of hyperglycemia, 47% demonstrated improvement, and 32% had no change or worsening hyperglycemia. When assessing secondary end points, results indicate HbA1c decreased by 0.84% (P <.0001) and daily insulin dose decreased by a mean of 30 units (P <.0001). Further analysis indicated hypercortisolism severity score (severe vs moderate/mild: OR, 2.4; 95% CI, 1.1-4.9) and Cushing syndrome subtype (nonadrenal vs adrenal: OR, 2.9; 95% CI, 1.3-6.4) were associated with hyperglycemia improvement, but not type of hyperglycemia (diabetes vs prediabetes: OR, 2,1; 95% CI, 0.9-4.9) at the end of follow-up.

“We demonstrated that almost 70% of patients with CS demonstrate either resolution or improvement in hyperglycemia following CS remission. As a group, patients demonstrate a decrease in HbA1c, and can be treated with less insulin and fewer non-insulin agents. Patients with more severe hyperglycemia, ACTH-dependent CS, and more severe CS are more likely to improve after surgery,” added investigators.

This study, “The impact of curative treatment on hyperglycemia in patients with Cushing syndrome,” was published in The Journal of the Endocrine Society.

Highlights

•

Cushing syndrome is an abnormality resulting from high level of blood glucocorticoids.

•

Iatrogenic Cushing syndrome due to the overuse of topical corticosteroids is rarely reported.

•

This report presents a case of topical corticosteroid induced iatrogenic Cushing syndrome in an infant.

Abstract

Introduction

Cushing syndrome (CS) is an endocrinological abnormality that results from a high level of glucocorticoids in the blood. Iatrogenic CS due to the overuse of topical corticosteroids is rarely reported. The current study aims to present a rare case of topical corticosteroid induced iatrogenic CS in an infant.

Case presentation

A 4-month-old female infant presented with an insidious onset of face puffiness that progressed over a 2-month period. The mother reported to have used a cream containing Betamethasone corticosteroid 5–8 times a day for a duration of 3 months to treat diaper dermatitis. Laboratory findings revealed low levels of adrenocorticotrophic hormone (ACTH) and serum. Abdominal ultrasound showed normal adrenal glands. The topical corticosteroid was halted and physiologic topical hydrocortisone doses were administered.

Clinical discussion

Infants are more likely to acquire topical corticosteroid induced iatrogenic CS due to their thin and absorptive skin, higher body surface area, and the high prevalence of conditions that necessitates the use of these medications. Most iatrogenic CS cases following topical steroid application have been reported in infants with diaper dermatitis that are most commonly treated with Clobetasol and Bethamethasone.

Conclusion

Infants are susceptible to develop CS due to topical corticosteroid overuse. Hence, physicians need to consider this in infantile CS cases, and take appropriate measures to avoid their occurrence.

1. Introduction

Cushing syndrome (CS) is a reversible endocrinological abnormality that results from high level of cortisol or other glucocorticoids in the blood [1]. It can be caused by either endogenous factors such as excess steroid production and secretion due to adrenal or pituitary tumors, or exogenously through prolonged use of corticosteroid medications resulting in iatrogenic CS [2]. Iatrogenic CS due to the overuse of oral or parenteral corticosteroids is common, however, while topical corticosteroids are one of the most widely prescribed medications by dermatologists, they are less frequently reported to cause iatrogenic CS [3,4]. Even though CS is very rare in the pediatric population with an annual incidence of only 5 cases per million, children of the pediatric age have a higher risk of developing iatrogenic CS, which is likely due to the high prevalence of conditions that necessitates the use of topical corticosteroids and the thinness of their skin that can more easily absorb the steroid [5,6].

The aim of the current study is to present a rare case of topical corticosteroid induced iatrogenic CS in an infant. SCARE guidelines are considered in writing this report [7].

2. Case presentation

2.1. Patient information

A 4-month-old female infant presented with an insidious onset of puffiness of the face; the swelling progressed over a period of 2 months without any other associated symptoms. The infant’s prenatal, developmental, and family history were insignificant, and she was born full term to consanguineous parents via caesarian delivery. After delivery she did not require neonatal intense care unit (NICU) and was discharged in good health. She has been given both bottle and breastfeeding every one to two hrs, and she has received all the required vaccinations at their proper times.

The mother reported to have used a topical corticosteroid cream (Optizol-B cream; a combination of Clotrimazole and Betamethasone) for a period of 3 months with a dose of 5–8 times a day to treat diaper dermatitis of the infant.

2.2. Clinical findings

The infant’s physical examination revealed facial puffiness (Moon face) with no body edema, and cutaneous examination showed the diaper rash without any other cutaneous manifestations. The infant was vitally stable with no dysmorphic features and no skeletal deformities. Her growth parameters were within normal limits, and her systemic examination was unremarkable.

2.3. Diagnostic approach

Laboratory findings revealed low adrenocorticotropic hormone (ACTH) level in the blood measuring 5.9 p.m./l, a serum cortisol level of 24 nmol/l, and normal serum sodium and potassium levels of 144 mEq/l and 4.8 mmol/l, respectively. Abdominal ultrasonography (US) showed normal adrenal glands.

2.4. Therapeutic intervention

The topical corticosteroid cream that contained Bethamethasone was halted and oral hydrocortisone was given (10 mg/m2) tapered over one month. The patient was given a card addressing Cushing syndrome to inform the health care providers in case of emergency situation or unexpected surgical intervention.

2.5. Follow-up and outcome

The infant’s facial puffiness was significantly improved after 7-month follow-up of the patient.

3. Discussion

CS is an endocrinological disorder resulting from high glucocorticoid level in the blood, it is categorized into ACTH dependent (due to pituitary tumors or excess ACTH administration) or ACTH independent CS (due to adrenal neoplasms or excessive glucocorticoid intake) [8,9]. Under normal circumstances, ACTH is secreted by the pituitary gland which in turn stimulates the secretion of cortisol by the adrenal glands [10]. Prolonged exogenous corticosteroid administration can lead to a number of adverse effects based on potency and duration of the treatment, including the suppression of hypothalamic-pituitary-adrenal (HPA) axis and iatrogenic CS, severe infections, and failure to thrive [11]. While iatrogenic CS is frequent with prolonged administration of oral or parenteral corticosteroids, it is occurrence due to topical corticosteroids have rarely been reported [12].

Multiple factors can increase the probability of acquiring the condition, such as corticosteroid potency, amount and frequency of application, age, skin quality, presence of occlusion, and duration of application [4]. In general, infants are more likely to develop topical corticosteroid induced iatrogenic CS, this is due to their thin and absorptive skin, higher body surface area, underdeveloped skin barrier, and the high prevalence of conditions that necessitates the use of these medications [5,6]. Most iatrogenic CS cases following topical steroid application have been reported in infants with diaper dermatitis [8]. This was also the case in this study. This is likely because the diaper area provides occlusion, the perineal skin has intrinsically absorptive properties, the steroid causes local skin atrophy, and percutaneous absorption is even more increased as the result of skin inflammation [13].

The most frequently used corticosteroid for the treatment of diaper dermatitis is reported to be Clobetasol followed by Bethamethasone, with a mean application duration of 2.75 (1–17) months to induce cortisol and ACTH levels suppression [4]. Typical clinical manifestations of CS include facial puffiness (Moon face), generalized body edema and obesity, hirsutism, buffalo hump, hypertension, skin fragility, and purple striae [3,5]. The causative corticosteroid in the current case was Bethamethasone that only resulted in facial puffiness (Moon face) without generalized body edema.

A specific and definitive diagnostic approach for iatrogenic CS is currently lacking [5]. However, prolonged exogenously administered glucocorticoids can suppress ACTH secretion which results in dismissing the need for proper endogenous production of cortisol [14]. Hence, almost all iatrogenic CS cases are associated with low ACTH and cortisol levels which can aid in the diagnosis of the condition [8]. Same findings were observed in this case. According to multiple studies, exogenous corticosteroid administration can often lead to HPA axis suppression alongside CS [15,16]. However, topical corticosteroid induced iatrogenic CS has been reported without HPA axis suppression [8].

The management of these cases start with the cessation of the causative corticosteroid medication and administration of physiologic topical hydrocortisone [5]. The same approach was followed in this study. In order to prevent the development of this condition in the first-place; clinicians should avoid prescribing high potency corticosteroids in the treatment of infantile dermatological disorders and instead choose low potency topical steroids, and also parents should be advised not to overuse these medications and only apply a thin layer to the affected area [6].

In conclusion, even though iatrogenic CS in infants is rare, overuse of topical corticosteroids can lead to their occurrence. Hence, physicians need to consider extensive steroid use as a causative agent of infantile CS. Appropriate measures need to be taken to avoid their occurrence by prescribing less potent steroids, limiting the use of high potent steroids, and informing parents about adverse effects of steroid overuse in infants.

A Case of Cushing’s Disease Presenting with Isolated Suicidal Attempt

Posted on November 2, 2021 by MaryO

Abstract

Cushing’s disease is an abnormal secretion of ACTH from the pituitary that causes an increase in cortisol production from the adrenal glands. Resultant manifestations from this excess in cortisol include multiple metabolic as well as psychiatric disturbances which can lead to significant morbidity and mortality. In this report, 23-year-old woman presented to mental health facility with history of severe depression and suicidal ideations. During evaluation, she found to have Cushing’s disease, which is unusual presentation. She had significant improvement in her symptoms with reduction of antidepressant medications after achieving eucortisolism. Cushing syndrome can present with wide range of neuropsychiatric manifestations including major depression. Although presentation with suicidal depression is unusual. Early diagnosis and prompt management of hypercortisolsim may aid in preventing or lessening of psychiatric symptoms The psychiatric and neurocognitive disorders improve after disease remission (the normalization of cortisol secretion), but some studies showed that these disorders can partially improve, persist, or exacerbate, even long-term after the resolution of hypercortisolism. The variable response of neuropsychiatric disorders after Cushing syndrome remission necessitate long term follow up.

Introduction

Endogenous Cushing syndrome is a complex disorder caused by chronic exposure to excess circulating glucocorticoids. It has a wide range of clinical signs and symptoms as a result of the multisystem effects caused by excess cortisol.1

The hypercortisolism results in several complications that include glucose intolerance, diabetes, hypertension, dyslipidemia, thromboembolism, osteoporosis, impaired immunity with increased susceptibility to infection as well as neuropsychiatric disorders.2,3

Cushing syndrome presents with a wide variety of neuro-psychiatric manifestations like anxiety, major depression, mania, impairments of memory, sleep disturbance, and rarely, suicide attempt as seen in this case.2,4

The mechanism of neuropsychiatric symptoms in Cushing’s syndrome is not fully understood, but multiple proposed theories have been reported, one of which is the direct brain damage secondary to excess of glucocorticoids.5

Case Report

A 23-year-old female presented to Al-Amal complex of mental health in Riyadh, Saudi Arabia with history of suicidal tendencies and 1 episode of suicidal attempt which was aborted because of religious reasons. She reported history of low mood, having disturbed sleep, loss of interest, and persistent feeling of sadness for 4 months. She also reported history of weight gain, facial swelling, hirsutism, and irregular menstrual cycle with amenorrhea for 3 months. She was prescribed fluoxetine 40 mg and quetiapine 100 mg. She was referred to endocrinology clinic at King Fahad Medical City, Riyadh for evaluation and management of possible Cushing syndrome as the cause of her abnormal mental health.

She was seen in the endocrinology clinic where she reported symptoms as mentioned above in addition to headache, acne, and proximal muscle weakness.

On examination her vital signs were normal. She had depressed affect, rounded face with acne and hirsutism, striae in the upper limb, and abdomen with proximal muscle weakness (4/5).

Initial investigations showed that 24 hour urinary free cortisol was more than 633 µg which is more than 3 times upper limit of normal (this result was confirmed on second sample with level more than 633 µg/24 hour), cortisol level of 469 nmol/L after low dose 1 mg-dexamethasone suppression test and ACTH level of 9.8 pmol/L. Levels of other anterior pituitary hormones tested were within normal range. She also had prediabetes with HbA1c of 6.1 and dyslipidemia. Serum electrolytes, renal function and thyroid function tests were normal.

MRI pituitary showed left anterior microadenoma with a size of 6 mm × 5 mm.

There is no abnormal signal intensity or abnormal enhancing lesion seen.

No further hormonal work up or inferior petrosal sinus sampling were done as the tumor size is 6 mm and ACTH level consistent with Cushing’s disease (pituitary source). She was referred to neurosurgery and underwent trans-sphenoidal resection of the tumor. Histopathology was consistent with pituitary adenoma and positive for ACTH. Her repeated cortisol level after tumor resection was less than 27 and ACTH 2.2 with indicated excellent response to surgery.

She was started on hydrocortisone until recovery of her hypothalamic pituitary adrenal axis documented by normal morning cortisol 3 months after surgery (Table 1).

During follow up with psychiatry her depressive symptoms improved but not resolved and she was able to stop fluoxetine 5 months post-surgery. Currently she is maintained on quetiapine 100 mg with significant improvement in her psychiatric symptoms.

Currently she is in remission from Cushing’s disease based on the normal level of repeated 24 hour urinary free cortisol and with an over-all improvement in her metabolic profile.

Discussion

Cushing syndrome is a state of chronic hypercortisolism due to either endogenous or exogenous sources. Glucocorticoid overproduction by adrenal gland can be adrenocorticotropic (ACTH) hormone dependent which represent most of the cases and ACTH independent.6 To the best of our knowledge this is the first case documented in Saudi Arabia.

There are multiple theories behind the neuropsychiatric manifestations in Cushing syndrome. These include increased stress response leading to behavioral changes, prolonged cortisol exposure leading to decreased brain volume especially in the hippocampus, reduced dendritic mass, decreased glial development, trans-cellular shift of water and synaptic loss, and excess glucocorticoid levels inhibiting neurogenesis and promoting neuronal tendency to toxic insult.3,7

In this report, the patient presented with severe depression with suicidal attempt. She had significant improvement in her symptoms with reduction of antidepressant medications but her depression persisted despite remission of Cushing disease. A similar case has been reported by Mokta et al,1 about a young male who presented with suicidal depression as initial manifestation of Cushing disease. As opposed to the present case he had complete remission of depression within 1 month of resolution of hypercortisolism.

In general, psychiatric and neurocognitive disorders secondary to Cushing syndrome improves after normalization of cortisol secretion, but some studies showed that these disorders can partially improve, persist, or exacerbate, even long-term after the resolution of hypercortisolism. This may be due to persistence hypercortisolism creating toxic brain effects that occur during active disease.2,8 Similar patients need to be followed up for mental health long after Cushing syndrome has been resolved.

Conclusion

Depression is a primary psychiatric illness, that is, usually not examined for secondary causes. Symptoms of depression and Cushing syndrome overlap, so diagnosis and treatment of Cushing disease can be delayed. Early diagnosis and prompt management of hypercortisolsim may aid in preventing or lessening psychiatric symptoms. The variable neuropsychiatric disorders associated with Cushing syndrome post-remission necessitates long term follow up.

Diagnostic pitfalls in Cushing’s disease impacting surgical remission rates; test thresholds and lessons learned in 105 patients

Posted on October 22, 2021 by MaryO

J Clin Endocrinol Metab. 2021 Sep 3:dgab659. doi: 10.1210/clinem/dgab659. Online ahead of print.

ABSTRACT

CONTEXT: Confirming a diagnosis of Cushing’s disease (CD) remains challenging yet is critically important before recommending transsphenoidal surgery for adenoma resection.

OBJECTIVE: To describe predictive performance of preoperative biochemical and imaging data relative to post-operative remission and clinical characteristics in patients with presumed CD.

DESIGN, SETTING, PATIENTS, INTERVENTIONS: Patients (n=105; 86% female) who underwent surgery from 2007-2020 were classified into 3 groups: Group A (n=84) pathology-proven ACTH adenoma; Group B (n=6) pathology-unproven but with postoperative hypocortisolemia consistent with CD, and Group C (n=15) pathology-unproven, without postoperative hypocortisolemia. Group A+B were combined as Confirmed CD and Group C as Unconfirmed CD.

MAIN OUTCOMES: Group A+B was compared to Group C regarding predictive performance of preoperative 24-hour urinary free cortisol (UFC), late night salivary cortisol (LNSC), 1mg dexamethasone suppression test (DST), plasma ACTH, and pituitary MRI.

RESULTS: All groups had a similar clinical phenotype. Compared to Group C, Group A+B had higher mean UFC (p<0.001), LNSC(p=0.003), DST(p=0.06), ACTH(p=0.03) and larger MRI-defined lesions (p<0.001). The highest accuracy thresholds were: UFC 72 µg/24hrs; LNSC 0.122 µg/dl, DST 2.70 µg/dl, and ACTH 39.1 pg/ml. Early (3-month) biochemical remission was achieved in 76/105 (72%) patients: 76/90(84%) and 0/15(0%) of Group A+B versus Group C, respectively, p<0.0001. In Group A+B non-remission was strongly associated with adenoma cavernous sinus invasion.

CONCLUSIONS: Use of strict biochemical thresholds may help avoid offering transsphenoidal surgery to presumed CD patients with equivocal data and improve surgical remission rates. Patients with Cushingoid phenotype but equivocal biochemical data warrant additional rigorous testing.

Metabolic profile differences in ACTH-dependent and ACTH-independent Cushing syndrome

Posted on October 10, 2021 by MaryO

Abstract

Background

The most common etiologies of Cushing’s syndrome (CS) are adrenocorticotropic hormone (ACTH)-producing pituitary adenoma (pitCS) and primary adrenal gland disease (adrCS), both of which burden patients with metabolic disturbance. The aim of this study was to compare the metabolic features of pitCS and adrCS patients.

Methods

A retrospective review including 114 patients (64 adrCS and 50 pitCS) diagnosed with CS in 2009–2019 was performed. Metabolic factors were then compared between pitCS and adrCS groups.

Results

Regarding sex, females suffered both adrCs (92.2%) and pitCS (88.0%) more frequently than males. Regarding age, patients with pitCS were diagnosed at a younger age (35.40 ± 11.94 vs. 39.65 ± 11.37 years, P = 0.056) than those with adrCS, although the difference was not statistically significant. Moreover, pitCS patients had much higher ACTH levels and more serious occurrences of hypercortisolemia at all time points (8 AM, 4 PM, 12 AM) than that in adrCS patients. Conversely, indexes, including body weight, BMI, blood pressure, serum total cholesterol, LDL-C, HDL-C, triglycerides, fasting plasma glucose, and uric acid, showed no differences between adrCS and pitCS patients. Furthermore, diabetes prevalence was higher in pitCS patients than in adrCS patients; however, there were no significant differences in hypertension or dyslipidemia prevalence between the two.

Conclusions

Although adrCS and pitCS had different pathogenetic mechanisms, different severities of hypercortisolemia, and different diabetes prevalences, both etiologies had similar metabolic characteristics.
