title: [Urinary excretion of vitamin A and thiobarbituric acid reactive substances in AIDS patients].
abstract: In the present investigation 28 serologically positive HIV-1 patients, 16 patients with AIDS (< 200/mm3 CD4+ T lymphocytes) and 12 with HIV-1 (200 to 500/mm3 CD4+ T lymphocytes) were studied. The Control Group consisted of 11 healthy individuals. The occurrence of alterations in the anthropometric parameters were higher in AIDS patients, compared to HIV-1 and controls patients, indicating a greater level of malnutrition. All individuals in present study showed normal plasma vitamin A levels. Contrasting, urinary excretion of vitamin A were higher in the AIDS Group (0.23 +/- 0.20 mumol/l) than in the HIV Group (0.19 +/- 0.12 mumol/l) and considerably higher than in the Control Group (0.06 +/- 0.05 mumol/l). Urinary excretion of TBARS also were higher in AIDS Group (3.34 +/- 2.65 mumol/l) compared to HIV (1.71 +/- 0.74 mumol/l) and Control Group (1.70 +/- 0.75 mumol/l). These results demonstrate a greater level of malnutrition and elevate excretion of vitamin A and SRATB in urine of AIDS patients. Therefore, monitoring of nutritional status, especially in relation to vitamin A is recommended for patients with HIV and AIDS.
