A preliminary report on basal & stimulated plasma cortisol in patients with acquired immunodeficiency syndrome. Indian Journal of Medical Research. 2000 Nov; 112(): 173-7http://imsear.searo.who.int/handle/123456789/22836BACKGROUND & OBJECTIVES: Structural and/or functional alterations in adrenal glands have been reported in human immunodeficiency virus (HIV) infection. However, no information has been reported from India. Hence a study was undertaken to assess the basal and circadian variations in plasma cortisol, and cortisol response to bolus ACTH in patients with AIDS. METHODS: Basal and stimulated plasma cortisol levels at 0800 h and 1600 h and, at 30 and 60 min following an intravenous bolus of 250 micrograms ACTH (short synacthen test, SST) were estimated in 15 patients with AIDS (CD4 < or = 200/microliter) and 12 healthy controls. The nature of the opportunistic infections and/or associated disease in each patient was also studied. RESULTS: The patients had higher median basal plasma cortisol levels as compared to the controls at 0800 h (540 nmol/l vs 415 nmol/l, P < 0.005) and at 1600 h (420 nmol/l vs 285 nmol/l, P < 0.003). Five patients (33%) exhibited abnormal circadian cortisol rhythms. All subjects in the control group and all but one (6.6%) in the patients group had normal peak plasma cortisol response (> or = 550 nmol/l) to SST. The lone patient with subnormal cortisol response had no feature of adrenal insufficiency. On the contrary, 3 patients clinically suspected to have adrenal insufficiency, had normal plasma cortisol response. INTERPRETATION & CONCLUSIONS: These findings suggest that most patients with AIDS have elevated basal plasma cortisol levels with abnormal circadian rhythm in some and normal adrenocortical reserve irrespective of the symptoms/signs of adrenal insufficiency.engAcquired Immunodeficiency Syndrome --bloodAdolescentAdrenal Cortex --physiopathologyAdultCase-Control StudiesFemaleHumansHydrocortisone --bloodMaleMiddle AgedComparative Study
