RESUMO
Background: Moringa oleifera Lam. is known to be of high nutritional and medicinal importance and has been demonstrated to possess a variety of biological activities. Objective: This study investigated the beneficial role of M. oleifera (moringa) supplementation in HIV positive subjects receiving antiretroviral drugs. Methods: Adult HIV positive individuals (104) attending the medical outpatient clinic in a tertiary health institution in Nigeria receiving highly active anti-retroviral therapies (HAARTs) were recruited in a randomized fashion for the study. Half of the subjects received moringa supplement (20 mg daily) additionally, while the others received only HAART and represented the control group. All subjects were monitored for 3 months during which their immunological status (CD4 counts and TNF-α), and hematological abnormalities at pre (baseline) and post study periods were determined. Results: Baseline levels of CD4 increased while TNF-α decreased significantly in control and moringa supplemented groups (p < 0.01). However, the post study CD4 values in the moringa group were higher and TNF-α values were lower compared to the control group (p < 0.01). In addition, baseline hematological abnormalities (anemia, thrombocytopenia, leucopenia, lymphopenia, and neutropenia) were improved but most significantly in the moringa supplemented subjects. Conclusion: The results suggest that moringa has immune-beneficial properties and improved hematological abnormalities in HIV positive individuals receiving antiretroviral therapy.
