17-ketosteroids and AIDS-Related-Complex

The serum free fatty acid (FFA), cortisol and urinary creatinine, 17-hydzoxycorticosteroid and 17-oxosteroid concentrations of acquired immunedeficiency syndrome (AIDS-I: beginning and AIDS-II: end phase) and AIDS-related complex (ARC) patients were determined. Both groups were compared to a control group (healthy men). ARC and AIDS-I patients. The ratios of stearic (C18:0) to oleic (C18:1) acid were 75%, P less than 0.01 (ARC) and 45%, P less than 0.05 (AIDS-I) greater than normal, due to a decrease in the relative percentage of monounsaturated fatty acids by 25%, P less than 0.001 (ARC) and 20%, P less than 0.01 (AIDS-I). In contrast, the relative percentage of polyunsaturated fatty acids was 85% greater than normal (P less than 0.001) in ARC and 100% greater than normal (P less than 0.001) in AIDS-I patients. Total FFA levels did not differ from controls. Serum cortisol levels were 35% (P less than 0.01) above normal in ARC and 60% (P less than 0.001) above normal in AIDS-I patients. Urinary 17-hydroxycorticosteroids and 17-oxosteroids were very low (2-3-fold lower than normal values, P less than 0.001) in both groups of patients. Urinary creatinine did not differ from controls. In AIDS-II patients the total FFA concentration was below normal 35% (P less than 0.01) and the stearic/oleic acid ratio was 50% above normal (P less than 0.05). The relative percentages of monounsaturated and polyunsaturated fatty acids in this group were similar to those of controls. Serum cortisol concentrations were significantly higher, 50% (P less than 0.001), but the urinary 17-hydroxycorticosteroids and 17-oxosteroids were 2-fold lower (P less than 0.001) than those of controls. Urinary creatinine did not differ from controls. These significant differences from normal may be implicated in the pathophysiology of AIDS and could represent not only a good index of diagnosis and prognosis, but also indicate new therapeutic approach to the disease.
