Primary Adrenal Insufficiency in Acute Progressive Systemic Inflammation Accompanied by Latent Tuberculosis: A Case Report

Abstract

A 64-year-old man presented with general malaise, edema, and other nonspecific symptoms, prompting extensive diagnostic evaluation. The patient's early morning cortisol and adrenocorticotropic hormone levels were consistent with primary adrenal insufficiency without evident secondary or tertiary causes on magnetic resonance imaging. The interferon gamma release assay (T-SPOT^®) was positive, suggesting latent tuberculosis, although there were no signs of active tuberculosis. The potential of extrapulmonary tuberculosis as a causative factor for adrenal insufficiency was explored but remained unconfirmed on contrast-enhanced computed tomography. Eosinophilia was detected, suggesting a link between adrenal insufficiency and the occurrence of atopic dermatitis. This case underscores the multifaceted nature of adrenal insufficiency and its potential associations. While autoimmune conditions are commonly associated with adrenal insufficiency, infectious diseases (e.g., tuberculosis) can also be contributing factors. Eosinophilia further indicates the likelihood of coexisting allergic or atopic conditions, particularly adrenal dysfunction. Although not dominant, the presence of latent tuberculosis can cause severe complications, including adrenal insufficiency, highlighting the requirement of vigilant monitoring. Clinicians are advised to consider adrenal insufficiency in the differential diagnosis of patients with generalized symptoms and perform comprehensive evaluations, including cortisol level assessment and tuberculosis screening.
