AB Ten-20% of patients with AIDS may present clinical evidence of primary
or secondary adrenal insufficiency. PURPOSE--To evaluate the
hypothalamic-pituitary-adrenocortical axis (HPAA) with CRH in patients
with AIDS. METHODS--We studied 20 patients with AIDS and 17 normal
subjects (NS) with exogenous ACTH (cosyntropin, 250 micrograms IV bolus)
followed one week later by ovine corticotropin releasing hormone (oCRH 1
microgram/kg BW IV bolus). Basal and 60' cortisol (micrograms/dL) were
determined in the former whereas ACTH (pg/mL) and cortisol were measured
every 15-30' for 2 hours in the latter. RESULTS--Basal and peak values
(mean +/- SD) of ACTH and cortisol for both tests were: cosyntropin test
(AIDS x NS): basal cortisol 22.5 +/- 7.1 x 10.6 +/- 3.6 (p < 0.01), peak
36.0 +/- 12.8 x 28.3 +/- 7.6 (p < 0.05); oCRH test: basal ACTH 42.2 +/-
33.5 x 28.9 +/- 12.7 (NS), peak 104.7 +/- 62.2 x 59.3 +/- 17.6 (p <
0.05); basal cortisol 19.7 +/- 9.0 x 10.1 +/- 3.4 (p < 0.01), peak 27.5
+/- 8.9 x 18.3 +/- 5.1 (p < 0.05). CONCLUSION--AIDS patients had
elevated basal and CRH stimulated ACTH levels and an intact
glucocorticoid pathway with elevated basal and peak cortisol levels to
both stimulation tests. This situation is probably due to the stressful
disease condition, where lymphokines may play a role activating the
hypothalamic-pituitary axis.
