Description of intervention(s) / exposure
Nutrtional intervention study.
The purpose of the study is to determine the effect of daily use (twice a day at anytime) of a food product for a period of one year among HIV positive patients. The study will be carried out in approximately 10 countries and approximately 800 patients will participate. Half of the patients will receive the active food product and half will receive the control food product. The food product consists of a mix of ingredients, including special proteins, fats, vitamins, minerals and fibres. Daily intake for the food products is as follows; Total fat 7.25g, Total protein 16.3g, Total carbohydrates 44.6g and oligosaccharides (soluble fibres) 15.0 g.

Treatment: Other
Comparator / control treatment
The control product is comprised of standard protein, carbohydrate and fatty acid sources to match the caloric intake of the active product.
Control group
Active

Outcomes
Primary outcome [1] 2194 0
To assess the effect of the food product (NR100157 - product code number) on immunological status as measured by CD4+ T-cell count (a specific T-cell lymphocte count).
Timepoint [1] 2194 0
CD4+ T-cell count will be measured at baseline and at approximately every 13 weeks to see if the food product improves immunological status, as determined by a decrease in CD4+ T-cell count .
Secondary outcome [1] 3824 0
To assess the effect of the food product (NR100157 - product code number) on: immune markers other than CD4+ T-cell count; viral load (HIV-1 RNA), weight, growth factors, study product compiance, study product appreciation, gastrointestinal tolerance, safety.
Timepoint [1] 3824 0
Assessments will be made at baseline and at approximately every 13 weeks. The primary study parameter will be a change from baseline.
