These results showed to an extent; taking high dosages of AZT with other combined drugs increased the CD-4 count and this in turn slowed down the replication of HIV & AIDS. Evaluation of the Study. Overall, this is not a good study as the sample size is not large enough giving a good representation of the population. Although they repeated the treatment after 24 weeks they should have made the period of evaluation a lot less short, to monitor the patients. In addition other external factors were not taken into account, which could have been reflected in the results they observed, e.g. diets. They did not mention if they included patients from different ethnic backgrounds, and did not have a placebo trial to see if any psychological effect had an effect on CD-4 count. By not having patients from different ethnic backgrounds and having a large sample size, the validity of the experiment was defeated.

In nutritional therapy, certain diets and nutritional supplements are used to strengthen a frail immune system. Supplements can also make up for the frequent nutrient deficiencies found in people with HIV infection and AIDS, which are often caused by chronic diarrhea and the body's reduced ability to absorb nutrients, or an eating disorder.

Naturopathic physicians, in particular, recommend a diet with plenty of fresh and organic vegetables, beans, and whole grains, and low in sugar, animal fats, alcohol, and caffeine. Nutritional supplements, many with antioxidant properties, that can be helpful to people with HIV infection and AIDS include: 1. vitamin A (beta-carotene) 2. vitamin C 3. vitamin B6 These alternatives have an approach to treating HIV but some may argue that it doesn?t give an immediate result in weeks like how AZT does.
