ABSTRACT
OBJECTIVE: To evaluate the nutritional intake and status of HIV-1 seropositive patients, as well as the relationship between malnutrition and disease stage. DESIGN: A cross-sectional study. SETTINGS: The Immunology Clinic at the Pelonomi Hospital in Bloemfontein, South Africa. SUBJECTS: Eighty-one HIV/AIDS patients in different stages of disease were recruited consecutively from January to May 1995. Eleven of these patients were followed in 1997. MAIN OUTCOME MEASURES: Anthropometric data including current weight, height, triceps skinfold thickness, mid-upper-arm circumference, body mass index and bone-free arm muscle area were collected. Nutrient intake was estimated using a diet history in combination with a standardised food frequency questionnaire. The patients were divided into 3 groups according to their CD4+ T cell counts. RESULTS: The men were leaner (BMI = 18.9) than the women (BMI = 22.7) and patients with a CD4+ T cell count < 200 (stage III) tended to have the lowest median values for all anthropometric measurements. More than half the patients had a low intake (< 67% of the recommended dietary allowances) of vitamin C, vitamin B6, vitamin D, vitamin A, calcium, iron and zinc. CONCLUSIONS: The results confirms that HIV/AIDS patients from this population are malnourished. There was, however, no association between disease stage and nutritional status. Nutritional supplementation of HIV/AIDS patients should be considered, as this might lead to improved immune function in these patients.

OBJECTIVE: To evaluate the nutritional status of HIV-1 seropositive patients with regards to laboratory parameters; the correlation between nutrient intake and actual values of nutrients, as well as the relationship between malnutrition and disease progression. DESIGN: A cross sectional study. SETTING: The Immunology Clinic at the Pelonomi Hospital in Bloemfontein, South Africa. SUBJECTS: 90 HIV/AIDS patients in different stages of disease were recruited consecutively from January to May 1995. Sixteen patients were followed up in 1997. MAIN OUTCOME MEASURES: The patients were divided into three groups according to their CD4+ T-cell counts, and blood levels of protein, albumin, cholesterol, ferritin, vitamin B12, magnesium, and phosphorus, as well as several micronutrients including vitamin E, vitamin C, beta-carotene and retinol which were determined using standard methods. These values were compared with the normal reference values used in the laboratory, and we tried to correlate these parameters with disease stage, as well as recorded nutrient intake in a subgroup of 35 patients. RESULTS: Abnormal values for several parameters, including plasma-retinol and serum-protein were found, but no correlation between more advanced disease and micronutrient deficiencies could be demonstrated. CONCLUSIONS: HIV/AIDS patients from this population are deficient in several micronutrients, and for some patients this is mirrored by a low intake. Multivitamin/anti-oxidant supplementation of HIV/AIDS patients should be considered, as this could lead to improved immune function in these patients.
