Objective: To determine the frequency of occurrence of hypoadrenalism in patients with human immunodeficiency virus (HIV) infection and document the clinical correlates of hypoadrenalism for this group of patients. Subjects and Methods: A descriptive study was carried out on 66 hospitalized HIV patients in a semi-urban setting of South Africa. Hypoadrenalism was diagnosed based on a basal cortisol level of less than 400 nmol/l with or without overt signs and symptoms. Clinical and biochemical parameters of hypoadrenalism were compared between subjects with suboptimal and normal cortisol levels. Statistical analysis included Student’s t test, χ² and Pearson’s correlation coefficient tests. Results: The prevalence of hypoadrenalism was 27% with a high occurrence of contributory factors (cytomegalovirus infection in 100% and tuberculosis in 68.2% of the study subjects). Typical features of hypoadrenalism included: hyponatremia, 19.6%; hyperkalemia, 6.1%; mucosal hyperpigmentation, 12%, and loss of axillary hair, 15%. Comparison of clinical and biochemical parameters of hypoadrenalism did not show a correlation between CD4 count and cortisol levels (r = 0.1 and p = 0.3). Conclusion: The prevalence of hypoadrenalism in our patients with HIV infection was high and the clinical features were comparable in subjects with normal and subnormal cortisol levels.

During a 2 year-period 12 Nigerians with sarcoidosis were diagnosed at the chest and dermatology clinics of the University College Hospital, Ibadan, Nigeria. Intrathoracic involvement was the commonest presentation followed by the skin, lymph nodes and liver. Histological diagnosis was obtained in all cases either from skin biopsy, transbronchial lung biopsy, lymph node or liver biopsy where applicable. This study suggests that sarcoidosis is not as rare as previous literature on the subject portrays.
