Overview
Tuberculous Addison's disease is a form of primary adrenal insufficiency caused by Mycobacterium tuberculosis infection, leading to adrenal gland damage and insufficient production of cortisol and aldosterone. It often presents with nonspecific symptoms including fatigue, weight loss, and hyperpigmentation 1.Diagnosis
Clinical Symptoms: Fatigue, weight loss, hyperpigmentation, hypotension, and electrolyte imbalances 1.
Laboratory Tests: Elevated ACTH levels, low cortisol levels (especially after ACTH stimulation test), hyponatremia, hyperkalemia 1.
Imaging: Abdominal CT or MRI may show adrenal gland atrophy or calcifications 1.
Tuberculin Skin Test/IGRA: Positive in many cases, aiding in diagnosis 1.
Histopathology: Biopsy showing granulomas consistent with tuberculosis 1.Management
Corticosteroids: Initiate with hydrocortisone or equivalent, adjusting dose based on clinical response and ACTH stimulation test results 1.
Salt Supplementation: Oral sodium chloride for managing hyponatremia and hyperkalemia 1.
Anti-tuberculous Therapy: Standard regimen (e.g., isoniazid, rifampin, ethambutol, pyrazinamide) for at least 6 months, tailored by local resistance patterns 1.
Monitoring: Regular follow-up with electrolyte levels, cortisol response, and clinical status 1.Special Populations
Pregnancy: Requires careful management of steroid doses to prevent fetal growth restriction while managing maternal adrenal insufficiency 1.
Elderly: Increased vigilance for electrolyte imbalances and cardiovascular complications due to potential pre-existing conditions 1.Key Recommendations
Initiate corticosteroid replacement therapy based on ACTH stimulation test results to manage cortisol deficiency (Evidence: Strong 1).
Combine anti-tuberculous therapy with adrenal replacement to address both underlying infection and adrenal insufficiency (Evidence: Strong 1).
Regularly monitor electrolyte levels and clinical symptoms in patients with tuberculous Addison's disease to adjust treatment effectively (Evidence: Moderate 1).References
