Two appetite stimulants, megestrol acetate and cyproheptadine were administered in a randomized trial to 14 patients who had no evidence of opportunistic infection or
malabsorption
but were wasted (had lost more than 5 kg body weight) as a result of human immunodeficiency virus (HIV) infection. Energy intakes were calculated from a 7 day weighed dietary record. Mean energy intakes per kilogramme body weight were similar in both treatment groups (greater than 34 kcal/kg) and were higher than that in well British males. Energy intakes increased by just over 500 kcal during both treatments, but fell to pretreatment levels after therapy. Patients in both treatment groups gained a moderate amount of weight. Megestrol acetate was associated with impotence in 4 patients. Insufficient calorie intake alone is not a common cause of wasting associated with HIV and the role of appetite stimulants is likely to be limited.

We measured plasma levels of all the antioxidant-micronutrients in subjects with HIV infection and controls. Plasma levels of all the carotenoids, including lutein, cryptoxanthin, lycopene, alpha-carotene and beta-carotene as well as vitamins A, C and E and cholesterol were assayed in 35 subjects with HIV infection and 38 controls. We found a significant depletion of all the carotenoids (P < 0.001) and vitamin C (P < 0.01) and cholesterol (P < 0.001) but not vitamins A or E in HIV-infected subjects. Further analysis of the HIV-infected subjects revealed that plasma levels of 4 of the groups of carotenoids and cholesterol were correlated with CD4 count but that beta-carotene and vitamins A, C and E were not. These results are reviewed in the light of the published literature and we conclude that these abnormalities of antioxidant-micronutrients are likely to reflect a metabolic phenomenon associated with HIV infection. However, an additional contribution to these deficiencies from
malabsorption
later in HIV disease cannot be ruled out.

Severe lactic acidosis has been increasingly reported as a potentially fatal complication of HIV treatment. We report on an asymptomatic HIV-infected woman treated with stavudine, lamivudine and indinavir for one year. She was hospitalized because of progressive dispnoea, oedema, cyanosis and severe lactic acidosis. Arterial blood pH was 6.98, bicarbonate 4.4 mmol/l (normal value 22-26), blood lactate: 29.7 mmol/l (normal value <2.2). Hepatic function was normal. She had an impressively rapid response (within a few hours) to empirical treatment with thiamine (100 mg i.v.). No evidence of sepsis or
malabsorption
were identified and vitamin B1 level was not tested before thiamine infusion. Three months later she was re-started successfully on nelfinavir plus nevirapine. The rapid response to thiamine infusion deserves a careful attention and such an approach should be considered in similar cases as a support treatment of this potentially life-threatening complication of HIV therapy.
