A Closer Look at Opioid-Induced Adrenal Insufficiency: A Narrative Review

Opioid-Induced Adrenal Insufficiency

This case report describes a woman in her 40s with opioid use disorder receiving methadone who was admitted for extended antibiotic treatment for methicillin-resistant Staphylococcus aureus bacteremia and was subesequently diagnosed with opioid-induced adrenal insufficiency.

Long-Term Opiate Therapy-Induced Secondary Adrenal Insufficiency: A Distinct Differential Diagnosis That Should Be Considered

Pain management with opioid medication is associated with several side effects. Opioid-induced adrenal insufficiency by suppression of the hypothalamic-pituitary-adrenal (HPA) axis is one of them that needs to be considered. The possible effects of opioid use on adrenal function are addressed in this case report. This is a case of a 21-year-old female patient with sickle cell disease who started, for the last year, on extended-release morphine sulfate 45mg daily in an attempt to control the severity of her pain and frequent admission with the vaso-occlusive crisis. She presented with a sepsis-like presentation and received vasopressor, empiric antibiotics, and glucocorticoid. She experienced low blood pressure and low blood glucose after weaning off of steroids. A diagnosis of secondary adrenal insufficiency was established after comprehensive reevaluation and confirmed by morning cortisol value and ACTH stimulation test. Her long-term use of opioids was considered the underlying cause of her secondary adrenal insufficiency after the exclusion of other causes and the normal pituitary gland on the brain magnetic resonance image. She received maintenance hydrocortisone. On follow-up, the patient showed effective improvement, and her adrenal function recovered after discontinuation of the morphine over the following six months. In conclusion, OIAI is an under-recognized condition of adrenal insufficiency secondary to long-term exposure to opioids. OIAI can cause symptoms and may result in potentially life-threatening adrenal crises, but it can be managed. A direct detrimental impact on the hypothalamus and pituitary gland mostly causes the suppression of cortisol secretion by opioids. Understanding how to diagnose and treat OIAI is crucial, particularly since opioids are widely used. To determine the frequency and clinical importance of opioid-induced adrenal insufficiency and if hormone replacement therapy is necessary, more research is required.

Endocrinopathies in Hemoglobinopathies: What Is the Role of Iron?

Hemoglobinopathies, including β-thalassemia and sickle cell disease (SCD), are common genetic blood disorders. Endocrine disorders are frequent manifestations of organ damage observed mainly in patients with β-thalassemia and rarely in SCD. Iron overload, oxidative stress-induced cellular damage, chronic anemia, and HCV infection contribute to the development of endocrinopathies in β-thalassemia. The above factors, combined with vaso-occlusive events and microcirculation defects, are crucial for endocrine dysfunction in SCD patients. These endocrinopathies include diabetes mellitus, hypothyroidism, parathyroid dysfunction, gonadal and growth failure, osteoporosis, and adrenal insufficiency, affecting the quality of life of these patients. Thus, we aim to provide current knowledge and data about the epidemiology, pathogenesis, diagnosis, and management of endocrine disorders in β-thalassemia and SCD. We conducted a comprehensive review of the literature and examined the available data, mostly using the PubMed and Medline search engines for original articles. In the era of precision medicine, more studies investigating the potential role of genetic modifiers in the development of endocrinopathies in hemoglobinopathies are essential.

Adrenal Crisis Masked as Septic Shock in a Patient With Opioid Use Disorder on Buprenorphine

Opioid-induced adrenal insufficiency is a known side effect of chronic opioid use, but opioid-induced adrenal insufficiency related to chronic buprenorphine-naloxone therapy is less well-known. We present a case of a patient with opioid use disorder on chronic buprenorphine-naloxone therapy admitted with presumed septic shock and found to be in an adrenal crisis. The patient presented to our hospital with a shock-like presentation, requiring vasopressors, intubation, empiric glucocorticoids, and antibiotics. As her steroids were weaned, she developed bradycardia and blood glucose in the 60s. A low- and high-dose cosyntropin stimulation test confirmed the presence of secondary adrenal insufficiency, presumed to be due to her chronic buprenorphine-naloxone use. She was discharged on maintenance hydrocortisone and continued buprenorphine-naloxone therapy. With the high prevalence of opioid use disorder and the common need for medication for opioid use disorder, it is important that healthcare providers properly identify opioid-induced adrenal insufficiency in order to quickly and correctly diagnose and treat adrenal crises.
