This study examined the potential effect of a nutritional supplement on the anthropometric profiles (body measurements such as body mass index [BMI], fat percentage and waist-hip ratio) of HIV-positive/AIDS patients and the correlation between anthropometric profile, CD4+T cell count and viral load. At baseline, of the 35 patients recruited into the study, 32 (94.1%) showed a fat percentage below normal range. Twenty-four of the patients (68.6%) had a BMI within normal range, while a greater percentage of the patients had a normal waist-hip ratio. Of the 28 patients that completed the study, 26 (96.3%) reported a fat percentage of below 18.5%. The results showed that 19 (67.9%) of the 28 patients had a BMI within the normal range after nutrient intervention. There was a significant positive correlation between the BMI and fat percentage. At the end of the study the CD4+T cell count showed no correlation with any of the anthropometric indices while the viral load showed a significant negative correlation with the lean body mass and BMI. The short duration of the study probably limited the positive trend of the supplement.

The effect of a nutritional supplement on the immune status and haematological parameters of HIV-positive/AIDS patients is tested using standard procedures. This clinical trial of 35 patients consists of a baseline visit and three months of supplementation from April to September 2003. Results showed that viral load decreased significantly (P<0.002) with time following supplementation. Mean cell volume (MCV) and mean cell haemoglobin concentration (MCHC) increased significantly (P<0.002 and P<0.0002, respectively), reflecting the positive effect of the supplement on these haematological parameters. Supplementation had no effect on CD4+ T-cell count, which decreased significantly with disease progression. Owing to certain limitations of the study (small sample size, short duration and the late stage of HIV infection), further studies are needed to confirm the effect attributed to the supplement.
