Adrenal disorders in people with HIV: The highs and lows

Disseminated tuberculosis in PLWHIV presenting as primary adrenal insufficiency

A woman in her 40s presented with a history of fatigue, symptoms of light-headedness on getting up from a sitting position and hyperpigmentation of the skin and mucous membranes. During the evaluation, she was diagnosed with primary adrenal insufficiency. Radiological imaging and microbiological evidence revealed features of disseminated tuberculosis involving the lungs and the adrenals. She was found to have an HIV infection. This patient was prescribed glucocorticoid and mineralocorticoid replacement therapy and was administered antituberculous and antiretroviral treatment.

Adrenal insufficiency in HIV/AIDS: a review

INTRODUCTION

Adrenal insufficiency (AI) is one of the most common potentially life-threatening endocrine complications in people living with human immunodeficiency virus (PLHIV) infection and acquired immunodeficiency syndrome (AIDS).

AREAS COVERED

In this review, the authors explore the definitions of relative AI, primary AI, secondary AI and peripheral glucocorticoid resistance in PLHIV. It also focuses on the pathophysiology, etiology, diagnosis and management of this endocrinopathy in PLHIV. A literature review was conducted through Medline and Google Scholar search on the subject.

EXPERT OPINION

Physicians need to be aware of the endocrinological implications of HIV infection and its treatment, especially CYP3A4 enzyme inhibitors. A high index of clinical suspicion is needed in the detection of AI, especially in PLHIV, as it may present insidiously with nonspecific signs and symptoms and may be potentially life threatening if left untreated. Patients with overt primary and secondary AI require glucocorticoid replacement therapy. Overt primary AI also necessitates mineralocorticoid replacement. On the other hand, the management of relative AI remains controversial. In order to reduce the risk of adrenal crisis during periods of stress, the short-term use of glucocorticoids may be necessary in relative AI.
