iatrogenic cushing syndrome

Sern Wei Yeoh
Direct acting antiviral (DAA) regimens containing ritonavir have been developed to treat hepatitis C, with fewer side effects than that by interferon-based regimens. However prescribers must be aware of drug-drug interactions. There are multiple reports of iatrogenic Cushing syndrome (CS) caused by ritonavir, when used to treat human immunodeficiency virus, increasing the bioavailability of exogenous steroids by inhibiting cytochrome p450 enzymes in the liver and gut wall and thus reducing steroid metabolism...

Ritonavir and cobicistat, used as pharmacokinetic enhancers in combination with some antiretrovirals (ARVs) for the treatment of HIV, are potent inhibitors of the CYP3A4 isoenzyme. Most glucocorticoids are metabolised via the CYP3A4 pathway and iatrogenic Cushing's syndrome (ICS), with possible secondary adrenal insufficiency (SAI), is a recognised complication following co-administration with ritonavir or cobicistat. A structured approach for identifying and managing potentially affected individuals has not been established...

Hypercortisolemia is associated with abdominal adiposity. Prior studies have quantified visceral adipose tissue (VAT) versus subcutaneous adipose tissue (SAT) accumulation as assessed by CT and MRI in patients with pituitary Cushing's disease (1-3) but not of other etiologies. Hormone differences in women with Cushing's syndrome due to pituitary versus adrenal and iatrogenic etiologies, including differences in DHEA production, may affect body composition.

Iatrogenic Cushing's syndrome (ICS) is caused by exogenous corticosteroid administration with suppression of the hypothalamic-pituitary-adrenal axis. It has been commonly described with oral and topical steroid use, but scarce reports have documented intranasal steroid usage as the etiology in infancy. In this article, we describe a case of a 4-month-old infant who developed ICS after 6 weeks of intranasal dexamethasone ophthalmic solution administration for nasal obstruction. To our knowledge, this is the youngest patient reported with ICS due to intranasal use of a prescribed dose of an ophthalmic steroid...

Glucocorticoids are used for the treatment of many diseases, such as inflammatory, allergic, autoimmune, and neoplastic diseases. They can be used in the form of topical, oral, inhalable, rectal, and intra-articular agents. Many topical steroid-related iatrogenic Cushing's syndrome cases affecting especially children have been reported in the literature. Topical steroid-related Cushing's syndrome is rarely seen in adults. In this report, we present the case of a 32-year-old male patient with iatrogenic Cushing's syndrome related to long-term clobetasol propionate treatment for psoriasis...

Cushing's syndrome is a state of cortisol excess, possibly from a tumor in the pituitary gland, the adrenal gland, or an ectopic nonpituitary ACTH-secreting source. The first form, pituitary in origin, was originally described by Harvey Cushing, MD, and was labeled as Cushing's disease. Long-term therapy with glucocorticoids also can lead to iatrogenic Cushing's syndrome.

Cushing's syndrome (CS) is relatively rare disorder affecting 2-5 per million per year, although the issue of establishing the diagnosis of CS and differential diagnosis of the disease are a significant clinical problem. CS is usually the result of excessive exogenous glucocorticoids usage (iatrogenic CS), endogenous CS can be divided into ACTH-dependent and ACTH-independent. Regardless of its etiology, the most important steps in establishing the diagnosis of CS are taking careful history and examination. The symptoms with high discriminatory value are myopathy, reddish purple striae, easy bruising and plethora...

The advent of highly active antiretroviral therapy for HIV infection dramatically changed the landscape of the disease. Ritonavir, a protease inhibitor (PI) frequently used in low doses to 'boost' the concentrations of other PIs, inhibits the cytochrome P450 3A4 isoenzyme, a common metabolic pathway to multiple drugs, so the potential for drug interactions is not negligible. A 39-year-old man with HIV-1 infection, treated with a ritonavir-boosted PI, was started on fluticasone/salmeterol inhaler and intranasal fluticasone, in 2009, in the setting of asthma and allergic rhinitis...

OBJECTIVES: The treatment goal in congenital adrenal hyperplasia (CAH) is to replace glucocorticoids while avoiding androgen excess and iatrogenic Cushing's syndrome. However, there is no consensus on how to monitor disease control. Our main objectives were to evaluate hormonal circadian rhythms and use these profiles to identify optimal monitoring times and novel disease biomarkers in CAH adults on intermediate- and long-acting glucocorticoids. DESIGN: This was an observational, cross-sectional study at the National Institutes of Health Clinical Center in 16 patients with classic CAH...

Ritonavir is a potent inhibitor of the cytochrome P450 enzyme CYP3A4 and is subject to multiple drug-drug interactions. This becomes especially important when the patient is also taking medications metabolized through CYP3A pathway as increased and potentially toxic drug levels may ensue. Herein we present one such interaction wherein a 57 year old gentleman with human immunodeficiency virus (HIV) infection on highly active antiretroviral therapy that included ritonavir, had addition of fluticasone inhaler to his medication repertoire for treatment of chronic obstructive pulmonary disease...

Home delivery, low birth weight babies and maternal illiteracy among the poor in rural India are frequent. The rural poor prefer to seek healthcare from private providers, most of whom have no formal medical training and buy medicines from private pharmacies without a prescription owing to a weakly regulated environment. This report is of a 4-month-old baby from a remote village in northern India, who presented with exogenous Cushing syndrome. This baby was a full-term low birth weight home delivery. As the baby was not growing well, treatment was started at 1 month by a private doctor with betamethasone drops The mother on her own volition continued giving the betamethasone drops by buying the medicine over the counter from a private pharmacy...

The present report describes the case of a woman diagnosed with an adrenocorticotropic hormone- (ACTH-) secreting thymic carcinoid associated with Cushing's syndrome. Treatment consisted of tumour resection and 131-I-meta-iodobenzylguanidine (MIBG) therapy. In spite of her iatrogenic menopausal state she twice became pregnant and delivered two healthy babies but developed recurrences during both pregnancies. The last recurrence presented as a primary breast cancer. Despite poor prognosis our patient survived for eleven years...

Here we report a case of a young male who developed full blown iatrogenic Cushing's syndrome after use of superpotent clobetasol propionate cream 0.05% for long duration to suppress psoriatic skin lesions. He also developed osteoporosis and hypogonadism. This case demonstrates that injudicious use of topical steroids can have disastrous consequences.

PURPOSE: We report a rare case of spontaneous eyeball luxation associated with exophthalmos due to iatrogenic Cushing syndrome (CS). The normalization of serum hormones led to the regression of the picture. CASE: A 64-year-old man presented with spontaneous globe luxation of the left eye after a 6-month history of bilateral, painless, and slowly progressive exophthalmos. The patient had been receiving weekly infusions of methylprednisone over the previous 6 months...

WHAT IS KNOWN AND OBJECTIVE: Budesonide, an oral glucocorticoid indicated for the treatment of Crohn's disease, rarely interferes with the hypothalamic-pituitary-adrenal axis because more than 80% of it is metabolized by cytochrome P450 enzymes. CASE SUMMARY: A 33-year-old female patient diagnosed with Crohn's disease, treated with oral budesonide, was admitted for Cushingoid symptoms and signs. The onset coincided with the use of fluvoxamine, a serotonin reuptake inhibitor and also a potent inhibitor of cytochrome P450 enzymes that presumably led to budesonide accumulation...

In DSM-5, bipolar disorder (BS) is no longer conceptualised as a pure mood disorder together with unipolar depression, but as a bridge between schizophrenia and depressive disorders. This nosological classification is founded on the historical context of the 19th century. In addition to unipolar depression and schizophrenia, schizoaffective disorder, borderline personality disorder and attention-deficit hyperactivity disorder (ADHD) overlap with BS symptomatology. Overlap also exists with somatic diseases such as multiple sclerosis, Cushing's syndrome and syphilis as well as iatrogenic affective syndromes...

Bronchial asthma (BA) and Allergic rhinitis (AR) are common clinical problems encountered in day to day practice, where inhalational corticosteroids (ICS) or intranasal steroids (INS) are the mainstay of treatment. Iatrogenic Cushing syndrome (CS) is a well known complication of systemic steroid administration. ICS /INS were earlier thought to be safe, but now more and more number of case reports of Iatrogenic Cushing syndrome have been reported, especially in those who are taking cytochrome P450 (CYP 450) inhibitors...
