Cushing Syndrome Leaves Lasting Health Effects

Posted on August 8, 2025 by MaryO

TOPLINE:

Compared with a matched population-based control group, patients with Cushing syndrome continued to exhibit elevated systolic and diastolic blood pressures along with reduced kidney function at least 14 years after biochemical remission.

METHODOLOGY:

  • Researchers in Germany conducted a retrospective cohort study to assess the long-term trajectory of blood pressure and kidney function in patients who achieved remission of Cushing syndrome.
  • They included 81 patients with Cushing syndrome (median age at baseline, 44 years; 75.3% women) and compared them with 243 matched control individuals from a population-based cohort.
  • Data were collected before treatment at baseline and at median follow-up intervals of 7.1 and 14 years after biochemical remission, with assessments of blood pressure, glomerular filtration rate, the prevalence of chronic kidney disease, and the use of antihypertensives.

TAKEAWAY:

  • Patients with Cushing syndrome had a significant reduction in blood pressure and required fewer antihypertensives at both 7 and 14 years vs baseline.
  • However, when compared with the control group, patients with Cushing syndrome had significantly elevated systolic and diastolic pressures at baseline and 7 and 14 years post-remission (P ≤ .0002 for all).
  • Although the proportion of patients on antihypertensive medications decreased in the Cushing syndrome group after remission was achieved, the prevalence of uncontrolled hypertension remained higher than in the control group at all follow-up points. In fact, reducing the use of these medications was associated with an increased risk for uncontrolled hypertension.
  • Kidney function assessed via glomerular filtration rate remained consistently lower among patients with Cushing syndrome than among control individuals at baseline and 7 and 14 years post-remission (P = .005, P < .0001, and P = .0359, respectively).

IN PRACTICE:

“Our findings provide further evidence that cardiovascular effects of hypercortisolism are not entirely reversible with the normalization of cortisol levels and enhance our understanding of the deteriorative long-term cardiovascular consequences of chronic hypercortisolism,” the authors wrote.

The Outcome of Abnormal Glucose Metabolism and Its Clinical Features in Patients With Cushing’s Disease After Curative Surgery

Posted on July 27, 2025 by MaryO

Abstract

Objective

To investigate the outcomes of abnormal glucose metabolism and its clinical characteristics in patients with Cushing’s disease (CD) who achieved biochemical remission after surgery.

Methods

Patients diagnosed with CD who achieved biochemical remission and underwent regular follow-up after surgery were enrolled. Pre- and postoperative clinical data were collected and analyzed.

Result

151CD patients were included, of whom 80 (53 %) had preoperative abnormal glucose metabolism, including 56 with diabetes mellitus (DM) and 24 with impaired glucose regulation (IGR). At one year after surgery, 57 patients exhibited improved glucose metabolism, accompanied by a significant reduction in the homeostasis model assessment of insulin resistance (HOMA-IR). Improvements were mainly observed at 3 and 6 months after surgery. At one-year after surgery, there were 20 patients with diabetes and 16 with IGR. Compared to those with NGT, these individuals exhibited a higher prevalence of hypertension, hyperlipidemia, fatty liver, and abnormal bone metabolism.

Conclusion

CD patients demonstrated a high incidence of abnormal glucose metabolism. Notably, approximately two-thirds demonstrated improved glucose metabolism one year after curative surgery, with the greatest improvements observed at 3- to 6-month postoperative follow-up.

Introduction

Cushing’s disease (CD) is characterized by excessive endogenous cortisol production caused by pituitary adrenocorticotropic hormone adenoma and is the main cause of Cushing’s syndrome (CS). Surgical resection of the tumor is the preferred treatment. Prolonged exposure to hypercortisolism increases the risk of metabolic abnormalities, including obesity, hypertension, glucose and lipid abnormalities, osteoporosis, etc. Additionally, it significantly elevates the risk of infection, thrombosis, and hypokalemia. Abnormal glucose metabolism is a common complication of CS, with an incidence ranging from 13.1 % to 47 %[1], and diabetes is an independent risk factor for mortality in CD patients[2].
Previous clinical studies have found that metabolic abnormalities such as diabetes, hypertension, and hyperlipidemia improve in CS patients who achieve biochemical remission after surgical treatment. However, the concept of improvement in glucose metabolism, the incidence of improvement, and its related factors are inconsistent in various reports. Previous studies primarily assessed the outcome of glucose metabolism based on plasma glucose results at a single fixed follow-up time after surgery. The lack of regular follow-up data makes it difficult to clearly understand the trend of postoperative plasma glucose changes, and there are no clinical data on when glucose metabolism begins to improve or change. Therefore, this study retrospectively analyzed the follow-up data of patients with Cushing’s disease in our hospital before and after surgery, and monitored the changes in glucose metabolism, to explore the characteristics and clinical features of such changes in patients with Cushing’s disease who achieved remission from CD following surgery..

Subjects

This study enrolled hospitalized patients with Cushing’s disease at Huashan Hospital, Fudan University from January 2014 to February 2020. Inclusion criteria were as follows: (1) Age ≥ 18 years; (2) diagnosis of Cushing’s disease according to the 2021 Consensus on the Diagnosis and Management of Cushing’s Disease, confirmed by pathology[3]; (3) biochemical remission after transsphenoidal surgery; (4) complete preoperative data and regular follow-up visits (including visits at 1, 3, 6, and

Patients’ baseline characteristics

A total of 168 patients with CD were admitted to Huashan Hospital from 2014 to 2020 with pathological diagnosis and regular postoperative follow-up; however, 17 patients were excluded due to no biochemical remission after surgery or relapse during follow-up (Fig. 1). Ultimately, 151 patients (32 males and 119 females) were included in this study. The baseline characteristics of the included patients were shown in Table 1. There were 80 cases (53 %) complicated with abnormal glucose metabolism

Discussion

CD was a rare disease often associated with abnormal glucose metabolism. Based on medical history and OGTT screening, we found that over half (53 %) of CD patients exhibited abnormal glucose metabolism before surgery, with 37.1 % being diagnosed with diabetes. Previous studies have shown that the prevalence of diabetes in CS patients ranged from 13.1 % to 47 %, and most reports falling between 35 % and 45 %, which is consistent with our findings [1,12,13]. However, it should be noted that CD

Reconstructive Liposuction for Residual Lipodystrophy After Remission of Cushing’s Disease

Posted on July 3, 2025 by MaryO

​Abstract

Cushing’s syndrome (CS) is often presented due to an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma, characterized by high chronic cortisol levels. Surgical resection of the pituitary adenoma is the primary treatment, but long-term metabolic and physical sequelae can persist, affecting psychological well-being and social functioning. Glucocorticoids are directly involved in alterations of fat metabolism, favoring centripetal adiposity. Even after hormonal normalization, patients may experience residual lipodystrophy. Impairment of body image may cause psychological distress and social isolation. The objective is to illustrate the potential therapeutic value of reconstructive liposuction in restoring body image and psychological well-being in a patient with persistent lipodystrophy after Cushing’s disease remission.

We report a case of a 16-year-old female with recurrent Cushing’s disease secondary to a pituitary microadenoma, confirmed by elevated urinary free cortisol and magnetic resonance imaging (MRI). It was initially treated with transsphenoidal resection in 2019; disease recurrence was confirmed and again treated in 2024. Despite intervention, the prolonged hypercortisolism developed into secondary lipodystrophy, leading to severe body image dissatisfaction and social withdrawal. Thyroid function remained euthyroid, ruling out metabolic contributors. Because of the psychological distress caused by persistent fat redistribution, the patient underwent elective liposuction in 2025. Postoperative follow-up revealed reduced psychological distress and improved well-being and self-esteem. Reconstructive liposuction can play a key role in the treatment and management of persistent post-CS lipodystrophy, contributing significantly to psychological recovery. Prospective studies evaluating surgical criteria and long-term psychosocial outcomes are needed to define eligibility criteria and assess outcomes, leading to the development of clinical guidelines for aesthetic interventions in post-CS recovery.

Introduction

Corticotroph pituitary adenomas (corticotropinomas) are pituitary tumors that secrete excess adrenocorticotropic hormone (ACTH), causing endogenous Cushing’s syndrome (CS). Most of these adenomas are sporadic and monoclonal, although in some rare cases, they are associated with germline mutations (e.g., in USP8) or genetic syndromes [1,2]. Clinically, excess ACTH causes a classic presentation with centripetal obesity, purple striae, muscle asthenia, hypertension, and emotional disturbances such as depression or anxiety [3-5]. Chronically elevated cortisol levels promote fat deposition in central body regions – face, neck, torso, and abdomen – at the expense of relative thinning of the limbs [3], leading to lipodystrophy that can seriously affect the patient’s quality of life.

At the molecular level, glucocorticoids stimulate the differentiation of preadipocytes into mature adipocytes and enhance lipoprotein lipase activity in peripheral fat tissues [6], thereby increasing the uptake of circulating fatty acids and the storage of triglycerides. At the same time, they increase hepatic lipogenesis and modulate cortisol receptor homeostasis (e.g., 11β-HSD1 in adipose tissue), favoring visceral fat distribution [6]. Although glucocorticoids can induce acute lipolysis, they exert chronic lipogenic effects – especially in subcutaneous adipose tissue – which promotes fat accumulation in the face, neck, and trunk [6]. This central adiposity, characteristic of CS, is further enhanced by increased hepatic lipogenesis and the overexpression of 11β-HSD1 in adipose tissue, which amplifies the local action of cortisol [6].

Case Presentation

In 2019, a 16-year-old female patient was initially diagnosed with a 4 × 3 mm pituitary microadenoma (Figure 1), following clinical suspicion of Cushing’s disease. The diagnosis was confirmed through imaging studies and endocrinological testing, which revealed consistently elevated urinary free cortisol levels ranging from 459 to 740.07 µg/24 hours (normal range: <50 µg/24 hours), indicative of endogenous hypercortisolism. No dynamic load tests (such as dexamethasone suppression or ACTH stimulation) were performed, as the diagnosis was supported by the clinical context and laboratory findings. Moreover, no clinical or biochemical evidence of adrenal insufficiency was observed during follow-up.

The lesion is localized within the anterior pituitary gland, consistent with an ACTH-secreting adenoma causing Cushing’s disease in the patient.

The patient underwent transsphenoidal endonasal resection of the pituitary tumor in 2019. Although initially successful, disease recurrence was confirmed, and a second endonasal transsphenoidal surgery was performed in 2024. Despite these interventions, the prolonged hypercortisolism led to the development of secondary lipodystrophy, manifesting as centripetal fat accumulation, a dorsal fat pad, and disproportionate truncal adiposity (Figure 2). These physical alterations had a significant psychosocial impact, as reported by the patient during follow-up visits, resulting in body image dissatisfaction, low self-esteem, and social withdrawal. No formal psychometric scales were administered.

A and B panels show the anterior and posterior views prior to liposuction, demonstrating centripetal adipose accumulation characteristic of Cushing’s syndrome. The C panel shows the intraoperative stage following abdominal and flank liposuction, with placement of drainage tubes, and visible reduction in subcutaneous fat volume.

A thyroid function panel revealed a slightly elevated thyroid-stimulating hormone (TSH) level (4.280 μUI/mL; reference range: 0.270-4.200), with total and free T3 and T4 values within normal limits, ruling out clinically significant hypothyroidism as a confounding factor for her phenotype. The biochemical profile suggested a euthyroid state, despite borderline TSH elevation, which was interpreted as a subclinical or adaptive response to chronic cortisol excess (Table 1).

Parameter Normal Range Patient’s Value
Cortisol (µg/24 hour) 58.0 – 403.0 459.5 – 740.07
TSH (µUI/mL) 0.270 – 4.200 4.280
Total T3 (ng/mL) 0.80 – 2.00 1.02
Free T3 (pg/mL) 2.00 – 4.40 3.33
Total T4 (µg/dL) 4.50 – 12.00 8.63
Free T4 (ng/dL) 0.92 – 1.68 1.36

A persistently elevated 24-hour urinary cortisol range is observed, consistent with endogenous hypercortisolism. The thyroid profile remains within normal limits, with a mildly elevated TSH in the absence of overt thyroid dysfunction. These findings support the functional and metabolic profile characteristic of Cushing’s syndrome.

The procedure targeted lipodystrophic regions identified through clinical examination and patient concerns, rather than formal imaging or anthropometric measurements. It aimed to restore body contour, alleviate somatic distress, and improve her overall self-perception and quality of life. Postoperative follow-up revealed patient-reported improvements in body image and psychological well-being. While these outcomes were not evaluated with formal instruments, the clinical improvement was evident and significant from the patient’s perspective, highlighting the role of plastic surgery not only as a reconstructive tool, but also as a therapeutic strategy for restoring dignity and social functioning in patients recovering from CS.

Discussion

After successful treatment of the pituitary adenoma, many metabolic parameters improve; however, fat distribution usually only partially reverses. Longitudinal studies show that, in the medium term, weight and abdominal circumference decrease, and there is some redistribution of fat toward the limbs following cortisol remission [3].

For example, Bavaresco et al. (2024) observed that, after hormone levels normalized, total fat was reduced and part of it shifted from the visceral area to the legs [3]. Nevertheless, their review highlights that a significant proportion of patients continue to present with residual visceral adiposity and moderate obesity (body mass index, or BMI >25), despite hormonal control [7]. In our case, truncal adiposity persisted based on clinical assessment, though no formal anthropometric measurements were performed.

Although liposuction is not traditionally considered first-line therapy for cortisol-induced lipodystrophy secondary to Cushing’s disease, increasing evidence from related lipodystrophic syndromes supports its clinical utility. For instance, in human immunodeficiency virus (HIV)-associated cervicodorsal lipodystrophy, Barton et al. (2021) conducted a 15-year retrospective analysis comparing liposuction and excisional lipectomy, finding that 80% of patients undergoing liposuction alone experienced recurrence, while none of the patients treated with excisional lipectomy showed recurrence – albeit with a higher risk of postoperative seroma formation [7]. These findings underscore that, while liposuction may be less durable than excision, it remains a viable option for selected cases, especially when used for contouring or as an adjunct [7]. Similarly, the Endocrine Society guidelines on lipodystrophy management emphasize the importance of personalized approaches, particularly when localized adipose accumulation contributes to persistent metabolic dysfunction or psychological distress [8]. Akinci et al. (2024) also highlight that, even in partial or atypical lipodystrophy syndromes, patients often report substantial impairment in quality of life due to disfiguring fat redistribution [9]. In this context, liposuction should not be dismissed as merely cosmetic but considered part of a functional and psychosocial rehabilitation strategy. The present case exemplifies this rationale, as the patient – despite biochemical remission of Cushing’s disease – continued to experience debilitating body image disturbances and emotional distress, which were ameliorated following targeted liposuction. This supports the integration of body-contouring procedures into multidisciplinary care protocols for endocrine-related lipodystrophies, especially when residual physical stigma persists after hormonal normalization [7-9].

Body image disorders, such as those secondary to CS or lipodystrophy, significantly impact self-perception, self-esteem, and social functioning. For example, a study by Alcalar et al. (2013) reported that patients with active Cushing’s disease had significantly lower SF-36 scores – particularly in emotional role functioning and mental health domains – compared to controls [10]. Similarly, Akinci et al. (2024) described that patients with partial lipodystrophy demonstrated marked reductions in EQ-5D index values and visual analog scale (VAS) scores, indicating impaired health-related quality of life [9]. These findings underscore that fat redistribution disorders can substantially compromise psychosocial well-being, even after endocrine remission.

This is especially relevant in women, where sociocultural stereotypes surrounding female physical appearance reinforce thinness, symmetry, and youthfulness as standards of personal value and social acceptance [1]. This societal context amplifies body dissatisfaction when visible physical changes occur, even after the clinical remission of endocrine diseases, often leading to social withdrawal, anxiety, or depression [3,10]. Within this framework, plastic surgery – such as reconstructive liposuction – has proven to be a valuable therapeutic tool, offering physical restoration that can enhance self-confidence and promote social reintegration [4]. Postoperative follow-up in our case revealed patient-reported improvements in body image and psychological well-being. While these outcomes were not assessed using formal psychometric tools, the clinical benefit was evident from the patient’s perspective. This aligns with prior findings demonstrating the psychosocial value of reconstructive surgery, which can enhance self-esteem and social reintegration after physical disfigurement [11,12]. These observations underscore the role of plastic surgery not only as a reconstructive intervention, but also as a therapeutic strategy for restoring dignity and quality of life in patients recovering from CS.

Although validated psychometric instruments such as the Body Image Quality of Life Inventory (BIQLI) and the Dysmorphic Concern Questionnaire (DCQ) are available to assess body image disturbances, these were not applied in our case. Nonetheless, they represent useful tools for evaluating subjective impact in both clinical practice and research settings. The BIQLI evaluates the effect of body image on various aspects of life – social interactions, self-worth, sexuality, and emotional well-being – using a Likert scale ranging from -3 (very negative impact) to +3 (very positive impact), providing a quantifiable assessment of its influence on quality of life [5]. The DCQ, on the other hand, identifies dysfunctional concerns about perceived physical flaws by assessing behaviors such as avoidance, mirror checking, and concealment; higher scores are associated with suspected body dysmorphic disorder (BDD) [6]. These tools are useful for initial diagnosis, surgical candidate selection, and postoperative follow-up, as they objectively measure subjective changes related to body image. Their advantages include ease of use, clinical validity, and applicability in research settings. However, they also have limitations: they do not replace comprehensive psychological evaluation, may be influenced by cultural context, and do not detect deeper psychiatric comorbidities. Therefore, a multidisciplinary and ethically grounded approach – integrating plastic surgery, endocrinology, and psychology – is essential to ensure safe and patient-centered treatment planning.

Aesthetic liposuction is associated with significant improvements in perceived body image and patient quality of life [11]. For example, Papadopulos et al. (2019) observed statistically significant increases in perception of one’s own body appearance and high satisfaction with postoperative results [12]. These aesthetic gains were accompanied by psychological improvements: the same study documented an increase in emotional stability and a reduction in postoperative anxiety [12]. Similarly, Kamundi (2023) found that nearly all assessed dimensions of quality of life improved after liposuction (p < 0.05 in most of them). Altogether, these findings suggest that liposuction not only corrects physical alterations typical of CS, but also strengthens self-esteem and psychological well-being by substantially improving satisfaction with one’s body image [11].

Moreover, self-esteem influences adherence to medical treatments and lifestyle changes. By improving self-image through reconstructive surgery, it is plausible that the patient feels more motivated to maintain healthy habits, such as diet and regular exercise, that prevent metabolic relapse [12,13].

Nonetheless, it is important to emphasize that liposuction, in this context, should be viewed as a reconstructive complement, not a primary treatment. There are no established protocols or formal guidelines that explicitly include plastic surgery in the care of cured CS; the decision is personalized, based on the residual functional and psychological impact.

Conclusions

Reconstructive plastic surgery, though not a primary therapeutic approach for CS, plays a key role in enhancing patients’ quality of life following remission. Liposuction, in particular, offers a safe and effective solution for persistent lipodystrophy, providing aesthetic benefits with minimal scarring, rapid recovery, and low complication rates in properly selected patients.

This case underscores the importance of addressing both physical and psychosocial sequelae after endocrine stabilization. A multidisciplinary approach – encompassing endocrinology, neurosurgery, and plastic surgery – not only restores physical appearance but also contributes to emotional recovery, self-esteem, and overall patient satisfaction.

Cardiometabolic Complications After Cushing’s Disease Remission

Posted on April 30, 2025 by MaryO

Abstract

Background and aim

Cushing’s disease (CD) is associated with phenotypic traits and comorbidities that may persist after the normalization of cortisol levels. Medical therapy is usually given in recurrent or persistent CD after transsphenoidal surgery. We aimed to investigate the impact of long-term normalization of daily cortisol secretion on clinical picture and cardiometabolic comorbidities, comparing surgical remission to medical treatment.

Methods

Monocentric retrospective study, two- and five-years observation. Sixty CD patients, with sustained normal 24-h urinary free cortisol (UFC) levels, divided group 1 (surgical remission, n = 36) and group 2 (medical remission, n = 24).

Results

Patients were different after achieving eucortisolism with surgery or medical treatment. Phenotypic traits: round face, dorsocervical fat pad, and bruisability persisted more prominently in the group 2, however abdominal obesity and muscle weakness persisted in both groups, especially in those patients with increased late-night salivary cortisol (LNSC). Hypertension: greater improvement was observed in group 1 (-31% vs. -5%, p = 0.04). Diabetes: less prevalent in group 1 after 2 years (2/36 vs. 9/24, p = 0.002), with a corresponding reduction in glucose-lowering treatments and persistence of impaired LNSC in diabetic patients (p < 0.001). Dyslipidemia: remained widespread in both groups, with minimal improvement over time (-22% in surgical and − 6% in medical cohort).

Conclusions

Surgical remission leads to faster and sustained improvements in clinical phenotype. However, obesity, arterial hypertension, and dyslipidemia do not completely revert in five years, especially during medical treatment. Most comorbidities persist despite UFC normalization, due to impaired LNSC: the recovery of cortisol rhythms confirms the remission of hypercortisolism.

Introduction

Cushing’s disease (CD) is caused by an adrenocorticotropic hormone (ACTH)-secreting pituitary tumor, resulting in persistent endogenous hypercortisolism. The cortisol excess leads to a typical clinical picture: round face, facial plethora, buffalo hump, cutaneous striae rubrae, easy bruising, proximal myopathy, weight gain with visceral obesity, hirsutism and acne [1,2,3]. Moreover, several comorbidities are cortisol-related: metabolic syndrome (visceral obesity, arterial hypertension, glucose intolerance or diabetes, and dyslipidemia), acquired thrombophilia, osteoporosis or vertebral fractures, immunological impairments with increased infection susceptibility, and psychiatric disorders [4]. The sum of physical changes and comorbidities leads to a reduced life expectancy and a worsening of the quality of life [5]. Pituitary trans-sphenoidal surgery (TSS) is the first-choice CD treatment [1]. Despite high remission rates (up to 90% in referral centers) [6], the risk of recurrence varies from 10 to 47% [7], especially in series with long-term follow-up. If surgery fails or is not feasible, cortisol excess can be managed with medical therapy. Not rarely, patients on cortisol-lowering therapy experience fluctuations of their cortisol levels, making outcome evaluations difficult and hardly standardized. The goals of CD treatment are to normalize cortisol levels, and to reduce the burden of comorbidities. The most used biochemical marker in clinical practice is urinary free cortisol (UFC), which estimates the cumulative daily secretion of cortisol, but does not offer information about cortisol rhythm [8].

In this study we compared two groups of CD patients with sustained normalization of 24-h UFC due either to post-surgical or medical cortisol-lowering therapy remission. The aim of the study was to analyze the impact of long-term normalization of hypercortisolism in terms of UFC, achieved with surgical or medical treatment, on endocrine parameters, cortisol-related clinical picture and comorbidities, in a five-years observation period of patients with CD.

Materials and methods

Subjects

Sixty CD patients were enrolled (75% female); the median age at diagnosis was 41 years (interquartile range [IQR] 32–52), followed at the Endocrinology Unit of Padua University Hospital from 2000 to 2021. This observational study was conducted in accordance with the STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) guidelines [9]. The study, following the guidelines in the Declaration of Helsinki, was approved by the ethics committee of Padova University Hospital (PITACORA, protocol No. AOP3318, ethics committee registration 5938-AO-24), and all patients gave informed consent. All data are included in the Repository of the University of Padova [10].

The first normalized UFC is considered as the starting point of observation at follow-up (two or five years). The cohort was divided into two cohorts: group 1 achieved CD remission after surgery, and group 2 achieved long-term eucortisolism during medical therapy. The inclusion criterion was 24-h UFC levels (mean of two collections) below the upper limit of normality during the observational period. Postoperative long-term adrenal insufficiency requiring substitutive glucocorticoid treatment (with hydrocortisone or cortisone acetate tablets) 12 months after surgery or new-onset hypopituitarism were considered exclusion criteria. The group 1 was made of 36 patients (69% female) in remission after successful TSS. The second group consisted of 24 patients (83% female) on long-term medical treatment for CD persistence (n = 17) or relapse (n = 4) after surgery and three patients in primary medical therapy for poor surgical eligibility, as shown in Fig. 1. Within group 2, nine patients underwent previous radiotherapy without efficacy, at least 5 years before reaching adequate biochemical control with medical treatment; none developed hypopituitarism. 14/24 patients (58%) were treated with a monotherapy and 11/24 (46%) with combined therapies during the observation period. Details on medical therapies are shown in Table 1. In particular, 3 patients were treated with metyrapone + pasireotide s.c., 1 with metyrapone + ketoconazole, 2 with ketoconazole and cabergoline, 1 with metyrapone + cabergoline, 1 with metyrapone + ketoconazole + cabergoline, 1 with metyrapone + ketoconazole + pasireotide s.c., 1 with metyrapone + ketoconazole + pasireotide s.c. + cabergoline. Metyrapone and ketoconazole were administered two/three times a day, pasireotide s.c. twice daily and cabergoline once daily in the evening.

Data collection and study design

Two researchers retrieved clinical and biochemical data independently from the local digital medical records. We considered as baseline visit the clinical and endocrine evaluation performed with active hypercortisolism. Therefore, the baseline visit consists in the pre-surgical evaluation in group 1, and in the post-surgical confirmation of active hypercortisolism in those in medical treatment (or diagnosis in case of primary treatment, group 2).

We considered clinical and biochemical outcomes during routine follow-up at two- and five-years in each group, starting from surgical remission or the beginning of a stable normalization of UFC under medical therapy. CD diagnosis was based on at least two parameters among 24-h UFC above the upper normal limit (ULN, at least two collections), unsuppressed cortisol levels (> 50 nmol/L) after 1 mg overnight dexamethasone test (1 mg-DST) or late-night salivary cortisol (LNSC) > ULN (at least two samples). In all subjects, CD diagnosis was considered in case of normal-high ACTH levels, positive response to dynamic tests (corticotropin-releasing hormone or desmopressin test, high-dose dexamethasone test), and, two cases, with petrosal sinus sampling (BIPSS) [11]. Long-term remission after TSS was defined through normal UFC, combined with serum cortisol levels < 50 nmol/L in the first month after surgery and need of glucocorticoid replacement therapy. A relapse of CD was defined as the reappearance of the typical signs and symptoms of CD associated with the alteration of at least two first-line screening tests. Presence/absence of clinical signs of CD (round face, facial rubor, buffalo hump, bruising, cutaneous red striae, acne, hirsutism and oligo/amenorrhea in females) were evaluated during outpatient visits by expert endocrinologists. The presence of hirsutism in females was measured according to the Ferriman–Gallwey score > 8 (extent of hair growth in 9 locations was rated 0–4). Proximal muscle strength was diagnosed if patients were not able to stand up from a low seated position with anteriorly extended arms. Bodyweight, body mass index (BMI), waist and hip circumference, systolic (SBP), and diastolic blood pressure (DBP) were assessed with calibrated tools. Overweight was diagnosed in patients with BMI 25–30 kg/m2, obesity with BMI > 30 kg/m2. Visceral obesity was diagnosed as waist circumference ≥ 94 cm in men and ≥ 80 cm in women, or with a waist/hip ratio (WHR) ≥ 1 according to International Diabetes Federation criteria. Arterial hypertension was diagnosed for SBP above 140 mm Hg and/or DBP above 90 mm Hg and/or in patients on antihypertensive drugs. Diabetes mellitus (DM) was diagnosed according to American Diabetes Association criteria or when patients were taking antidiabetic medication. Dyslipidemia was diagnosed when low-density lipoprotein (LDL) calculated cholesterol was ≥ 100 mg/dL and hypertriglyceridemia when triglycerides were ≥ 150 mg/dL or when patients were on lipid-lowering medication. The presence of carotid vascular disease (CVD) has been assessed by supra-aortic vessels duplex ultrasound. Cushing’s cardiomyopathy (CCM) was diagnosed by doppler echocardiography with evidence of impaired relaxation and left ventricular filling pattern. The medical history was checked for cardiovascular disease (acute coronary syndrome, ACS) in all cases. A shortened activated partial thromboplastin time (aPTT < 29 s) defined pro-thrombotic status.

Assays

All biochemical analyses were carried out in an ISO15189:2012-accredited clinical laboratory [12], cortisol levels have been measured in urine or saliva with a mass-spectrometry home-made validated method. UFC was determined by a home-brew liquid chromatography-mass spectrometry (LC-MS/MS) method (intra-assay/interassay coefficient of variation [CV] < 6%/< 8%) since 2011 [13], previously by a radio-immunometric assay (Radim, intra-assay/interassay CV < 3%/< 9%). The patients were instructed to discard the first morning urine void and to collect all urine for the next 24 h, so that the morning urine void on the second day was the final collection. The sample was kept refrigerated from collection time until it was analyzed: normal range for UFC is 16–168 nmol/24 h.

Salivary cortisol was measured by a radio-immunometric assay (Radim, intra-assay/interassay CV < 3%/< 9%) until 2014 [14], after then by LC-MS/MS method (intra-assay/interassay CV < 6%/< 8% [15]). In order to prevent food or blood contamination, samples were collected at least 30 min after subjects had eaten, brushed their teeth, smoked or assumed liquorice; undertaken using Salivette® devices containing a cotton swab with or without citric acid (Sarstedt, Nümbrecht, Germany). The sample was stored at − 80 °C, before analyses [15].

The 1-mg DST test was performed orally assuming 1 mg of dexamethasone between 11 P.M. and midnight, sampling serum cortisol the next morning at 8 A.M. Serum dexamethasone levels, routinely evaluated since 2017, were adequate in all cases [16]. Serum cortisol (RRID: AB_2810257) and ACTH (RRID: AB_2783635) were determined by immune-chemiluminescence assay (Immulite 2000, Siemens Healthcare). Dynamic second-line tests and BIPSS were performed according to international standards.

Statistical analysis

Data were analyzed using SPSS Software for Windows, version 24.0 (SPSS Inc). Data are reported as medians and interquartile range or as percentages. The comparison between continuous variables was performed by non-parametric Wilcoxon test or Mann–Whitney test, as appropriate. The comparison between categorical variables was performed by the χ2 test. The correlation between continuous variables was performed by linear regression analysis. The level of significance for the overall difference between the groups was tested with one-way ANOVA. A p value < 0.05 was considered statistically significant.

Results

Endocrine evaluation

At baseline the two groups were similar for morning serum/salivary cortisol, LNSC, cortisol after 1 mg DST and morning ACTH levels (Table 3); UFC levels were higher in the surgical cohort (p < 0.001). Endocrine parameters were not influenced by sex and BMI. At baseline, all patients had impaired salivary cortisol rhythm with increased LNSC and inadequate cortisol suppression after 1-mg DST. At two years the recovery of salivary cortisol rhythm was observed in 97% of patients after surgery and 50% of patients during medical therapy. The only patient who did not show recovery of cortisol rhythm in the surgical cohort had LNSC of 5.4 nmol/L (range 0.5–2.6 nmol/L), with adequate cortisol suppression after 1-mg DST and sustained normal UFC: it was considered a false-positive due to residual minor depression state.

Table 3 Biochemical pattern at baseline and during the follow-up

Adequate cortisol suppression after 1-mg DST (both with normal UFC and LNSC) was observed in 34 out of 36 patients (94%) in the surgical cohort; the two patients who did not show complete cortisol suppression after 1-mg DST had cortisol levels of 60 and 119 nmol/l, respectively. On the contrary, as per selection criteria, none of the patients in group 2 presented suppressed cortisol after 1-mg DST.

At 5 years follow-up, all cases in the surgical cohort had suppressed cortisol after 1-mg DST and normal salivary cortisol rhythm, whereas in group 2 9% had suppressed cortisol after 1-mg DST and 36% recovered salivary cortisol rhythm. At 5 years, UFC and salivary cortisol levels (either morning or late night) were similar in the two groups, while the median value of serum cortisol after 1-mg DST remained not adequately suppressed (median 75 nmol/L, from 18 to 257 nmol/L) during medical therapy (See Table 3). In group 2, patients on combined therapy had higher UFC (102 vs. 76 nmol/24h p = 0.03) and LNSC (2.4 vs. 1.9 p = 0.05) at 5 years, compared to patients on monotherapy.

Hirsutism, abdominal obesity, round face and facial rubor were prevalent in group 1 at baseline. On the contrary, the abdominal obesity, facial rubor and easy bruising were most commonly found in the medical cohort. The prevalence of facial rubor, buffalo hump and bruisability was higher after medical than surgical remission after 2 years of eucortisolism; at 5 years the prevalence of buffalo hump and bruisability was higher in patients under drug therapy as well (Table 4; Fig. 2). Higher levels of UFC at baseline were observed in all patients with proximal myopathy (p < 0.001).

Arterial hypertension

Arterial hypertension (AH) was the most frequent comorbidity in both groups at baseline, with similar distribution in the two groups (Table 5). The prevalence of AH decreased after two years in both groups, especially in the surgical cohort (64% vs. 44% in group 2, p < 0.001; 75% vs. 71% p = 0.003), with no further improvement after five years. Overall, hypertensive patients were older at diagnosis (45yrs vs. 31y; p < 0.001) and with larger BMI (29 vs. 25 kg/m2; p = 0.03). Median UFC, morning salivary cortisol and LNSC, and 1-mg DST were not different in patients with/without AH at baseline and at 2 years. SBP and DBP values were similar in the two cohorts and were not correlated to UFC, LNSC or 1-mg DST throughout the follow-up. At 2 years, hypertensive patients had higher levels of morning salivary cortisol and LNSC with impaired rhythm (respectively 10.4 vs. 6 nmol/L, p = 0.01 and 3.2 vs. 1 nmol/l, p = 0.007). SBP and DBP values did not change during the five-years observation time in both groups; however, the number of anti-hypertensive drugs was higher in group 2 than in group 1 (p = 0.007). Overall patients treated with metyrapone showed higher values of DBP at 2 years (mean 89.4 vs. 81.7 mmHg, p = 0.01), the prevalence of AH did not differ from patients with other medical treatments.

Table 5 Two- and five-years changes in cardio-metabolic cortisol-related comorbidities of CD from baseline in group 1 and group 2

Glucose metabolism

DM prevalence at baseline did not show a correlation with BMI and age at CD diagnosis. DM prevalence was similar in group 1 and 2 after two and five years of follow-up. The follow-up analysis of DM was performed excluding patients in pasireotide, since its known impact in glucose metabolism. In both groups, median UFC, morning salivary and LNSC, and 1-mg DST were similar in patients with/without DM at baseline. At 5 years, patients with diabetes had higher levels of morning salivary cortisol and LNSC with impaired cortisol rhythm (respectively 15 vs. 7 nmol/L, p < 0.001 and 5.4 vs. 1.5 nmol/l, p < 0.001). None of the explored hormonal parameters was correlated with HbA1c levels in both groups at any time point considered. The number of antidiabetic drugs was higher after medical than surgical remission (Table 5).

As expected, patients treated with pasireotide had higher incidence of newly onset DM at 2- and 5 years (p = 0.02 and p = 0.05 respectively) and required more antidiabetic drugs at 2- and 5 years (p = 0.002, p = 0.05) or insulin units at 5 years (p = 0.03). HbA1c levels during pasireotide were higher than patients treated with other drugs (55.6 vs. 38 nmol/l, p = 0.002), requiring a higher number of antidiabetic drugs (p = 0.008). Patients on combined therapy with pasireotide had higher rates of DM at 2- and 5 years (p < 0.001 and p = 0.01) and used more antidiabetic drugs at 2- and 5 years (p = 0.004, p = 0.01) than those on monotherapy.

Lipid metabolism

The prevalence of dyslipidemia was similar in the two groups at baseline and after two years, and higher in the medical remission cohort after five years (p = 0.01). Overall, dyslipidemic patients were older at diagnosis (46y vs. 36y; p = 0.006) and had higher BMI (30 vs. 25 kg/m2; p < 0.001). There was no correlation between hormone parameters and LDL or triglycerides levels. Lipid profile was similar between patients treated with different drugs.

Vascular disease and coagulative profile

There was no difference between the two groups, at baseline, in the prevalence of carotid vascular disease, history of ACS, and CCM; at 5 years, in both groups, no patient had a worsening of a previously diagnosed stenosis, or novel diagnosis of CVD, ACS and CCM.

The median aPTT value at baseline was in the pro-thrombotic range in both groups (25s), without sex and BMI differences. No correlation was observed between aPTT and UFC, LNSC and 1-mg DST levels. Patients who manifested easy bruising, had shorter aPTT at 2- and 5 years (median 24 vs. 27s, p = 0.03). aPTT does not increase within both groups at 2- and 5-years and aPTT was shorter during medical therapy compared to surgical remission both after 2 and 5 years (22.5s vs. 27s, p = 0.02 at 2y and 23.5s vs. 27.9s, p = 0.02 at 5y).

Discussion

The impact of CD remission on clinical picture and hypercortisolism-related comorbidities is still controversial. The current knowledge suggests that long-term CD surgical remission is associated with increased metabolic and vascular damage, not only if compared to active disease, but also even after long-term normalization of cortisol secretion [17]. If CD recurs after successful TSS, or if surgery fails/is not feasible, cortisol excess can be treated with medical therapy. Likewise, long-term studies (> 2 years) on the clinical effects of medical therapy on CD are lacking. Some prospective registry studies have been published [1], only one retrospective study on long-term use of ketoconazole described a multicentric cohort of CD patients without a control group [18].

In our study, we enrolled 60 patients with CD diagnosed and treated in a single tertiary care center, with sustained and long-term (2 and 5 years) UFC normalization after surgery or during medical therapy. As expected, UFC levels at baseline were different in the two groups, due to the distinct starting point of medical history: a patient with persistent-recurrent CD after pituitary surgery presents with lower UFC than the new diagnosis. After surgical remission, patients achieved the recovery of salivary cortisol rhythm and the complete suppression of cortisol after 1-mg DST (investigated after substitutive glucocorticoid treatment discontinuation) in almost all cases. On the contrary, if eucortisolism is achieved with long-term medical therapy the recovery of salivary cortisol rhythm was observed only in half of patients and only few of them showed cortisol suppression after 1-mg DST within the 5 years observation time. Patients who were more resistant to the recovery of cortisol rhythm were more likely to receive combined treatment, even if no treatment is superior to others in normalizing salivary cortisol rhythm, in line with previous reports [1, 18, 19].

Within 2 years, patients in the surgical remission group showed a marked improvement of all phenotypic traits common at CD diagnosis compared to those in medical therapy. As observed also in other series of CD patients in remission [20], abdominal obesity persisted more than other clinical features over time, leading to an impaired body composition especially in the medically treated group [21]. Considering hyperandrogenism, acne improvement was more relevant at 2 and 5-years of follow up, probably due to a differential effect of ACTH-dependent adrenal androgens compared to hirsutism.

The impaired cortisol rhythm was a predictor of the long-lasting of most CD phenotypic features, as round face, buffalo hump, facial rubor, abdominal obesity, proximal myopathy and bruisability. A more severe clinical phenotype at baseline can explain a reduced control of hypercortisolism in monotherapy, requiring drug combination, and signs or symptoms are likely to persist despite the normalization of UFC [22]. In this study, no medication outperformed the others in terms of recovery from the CD phenotype.

The aetiology of hypertension and dyslipidemia is known to be heterogeneous, since both are influenced also by age at diagnosis and BMI, causing low rates of remission after UFC normalization [23, 24]. Arterial hypertension showed a decreasing trend with the best response within 2 years after UFC normalization only after surgical remission. Patients with disrupted salivary cortisol rhythm were more likely to remain hypertensive during the 5 years follow-up. Likewise, DM persistence during follow up correlates to impaired salivary cortisol rhythm and not with UFC. This finding is in contrast with the observations of Schernthaner-Reiter et al. [25]. on CD remission, and, on the contrary, supports data described by Guarnotta et al. [22]. Newell-Price et al.. recently found that when UFC and LSNC are both normal in patients treated with pasireotide, the rise in HbA1c levels is less evident than in patients with normal UFC but uncontrolled LNSC [26]. This observation underlines the importance of the impaired cortisol rhythm in the glucose impairment pathogenesis in CD. During the 5 years observation time, a worsening of previously diagnosed cardiovascular conditions, or novel acute vascular events, was not observed in both groups. This finding suggested that normalized UFC and intensive treatment of cardio-metabolic CD comorbidities play a fundamental role in reducing cardiovascular mortality [27]. A minor impact of CD therapy was observed in dyslipidemia, which persisted in both groups, with minimal improvement over time (−22% in surgical and − 6% in medical cohort). The criterion of 100 mg/dL LDL cut-off identifies a moderate CV risk reflecting the main focus of the study: the assessment of cardiometabolic complication after CD remission, assuming that they present a lower cardiovascular risk compared to patients with overt hypercortisolism.

Plasma hypercoagulability, with shortened aPTT, was found in all patients with active hypercortisolism. In the 5 years observation time, this parameter showed latency in increasing in both groups and in none achieved normality (> 28s). As previously observed in other studies, no correlation is observed between aPTT and any of the explored hormonal parameters [22, 28]. At 2- and 5 years, instead, shorter aPTT was observed during medical treatment than after surgical remission cohort. In both groups a shorter aPTT was associated with bruisability, which is related to impaired LNSC, strengthening the role of the impaired cortisol rhythm as a major driver of hypercoagulability. Also, Ferrante et al.. observed the long latency of plasma hypercoagulability, persisting for years after biochemical remission of CD: in that series thrombophilia appeared to be reversible within 5 years [29], while in our cohort the recovery takes longer.

Additionally, sexual differences characterize patients with patients with Cushing’s syndrome and hypogonadism in hypercortisolism is known to further increase the cardiovascular risk [30, 31]. However, it was not an interfering factor in our study population since hypopituitarism was considered an exclusion criterion, no case of new-onset hypogonadism was reported (even in male patients treated with ketoconazole), and the menopause transition in six women during the observation was not considered relevant.

The limits of the present study are its retrospective design, the variability of concomitant treatments, the heterogenous combinations of medical therapy used in clinical practice, the presence of treatment-specific adverse events that mimic the effects of hypercortisolism (such as pasireotide-induced DM and hypertension with metyrapone), the unpredictable effect of previous treatments, including radiotherapy. We considered UFC and LNSC as markers of hypercortisolism remission; nonetheless we acknowledge that both of them present some limitations, especially during medical treatment. The former considers the whole cortisol secretion during the day, and albeit UFC normalization is the main outcome of all trials for medical treatment [32, 33] it does not detect mild hypercortisolism. On the other hand, a normal LNSC does not fully reflect a normal circadian rhythm: only high cortisol levels in the morning with a decline in the night are able to restore clock-related activities [34].

Its strengths are the complete patient characterization in a single tertiary care center, the comparative study design, and the standardized protocols for diagnosis and long-term follow-up. In particular, samples have been processed within a single laboratory with accurate methods (LC-MS for urinary and salivary steroids), and all endocrine aspects of hypercortisolism were considered (overall daily cortisol production by UFC, circadian cortisol rhythm, and the recovery of the hypothalamic-pituitary axis by 1-mg DST overnight test).

To conclude, despite UFC normalization in both groups during follow-up, surgical remission results in more rapid and relevant improvements in CD phenotype and comorbidities. During medical therapy the UFC levels can be higher than after surgery, although in the normal range, and the normalization of LNSC is not always achieved: both conditions suggests that stricter criteria should be considered to define eucortisolism in patients with CD under medical treatment. Conditions such as obesity, hypertension, dyslipidemia, and hypercoagulability are not completely reversible in a 5-year observation time even in the surgical remission group. This observation underlines that all the comorbidities, independently of the normalization of UFC, must be intensively treated. Moreover, UFC normalization should not be considered the only biochemical goal to be reached, since the persistence of comorbidities seems to be more related to an impaired cortisol rhythm rather than to the cortisol secretory burden.

Leukocytosis in Cushing’s Syndrome Persists Post-Surgical Remission and Could Predict a Lower Remission Prognosis in Patients with Cushing’s Disease

Posted on March 21, 2025 by MaryO

Abstract

Context

Leukocytosis frequently noted in Cushing’s syndrome (CS), along with other blood cell changes caused by direct and indirect cortisol effects.

Objective

Assess baseline white blood cell (WBC) profile in CS patients compared to controls and WBC changes pre- and post-remission after surgical treatment for CS.

Design

A comparative nationwide retrospective cohort study.

Setting

Data from Clalit Health Services database.

Patients

297 patients (mean age 51 ± 16.1 years, 73.0% women) with CS and 997 age-, sex-, body mass index-, and socioeconomic status-individually matched controls. Ectopic CS or adrenal cancer patients were excluded.

Main outcome measure

Mean WBC, neutrophils, and neutrophil-to-lymphocyte ratio (NLR) two-years before and after pituitary or adrenal surgery. WBC and neutrophils are expressed as Kcells/µl.

Results

At baseline, leukocytosis was observed in 21.5% of patients with CS vs. 8.9% of controls (P < 0.001). Patients with CS had significantly higher WBC (8.8 ± 2.88 vs. 7.54 ± 2.45, p < 0.0001), neutrophils (5.82 ± 2.38 vs. 4.48 ± 1.97, p < 0.0001), and NLR (3.37 ± 2.63 vs. 2.27 ± 1.86, p < 0.0001) compared to controls, regardless of pituitary or adrenal source of hypercortisolemia. Post-surgery, patients with CS experienced significant decreases in mean WBC (-0.57 ± 2.56, p < 0.0001), neutrophils (-0.84 ± 2.55, p < 0.0001), and NLR (-0.63 ± 2.7, p < 0.0001). Despite achieving disease remission, patients with CS still had higher WBC (8.11 ± 2.4 vs. 7.46 ± 2.17, p = 0.0004) and neutrophils (4.71 ± 2.10 vs. 4.41 ± 1.87, p = 0.03) compared to controls. Patients with CD and baseline leukocytosis had lower remission rate than those with normal WBC (36.7% vs. 63.9%, p = 0.01).

Conclusions

At diagnosis, CS patients have elevated WBC, neutrophils, and NLR compared to controls. Remission does not normalize WBC levels in all patients, and baseline leukocytosis predicts a poorer remission prognosis in CD.
