Effect of Probiotics on the Frequency of CD4+ T-Cells in HIV-Infected Children and Adolescents: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

HIV infection is associated with a progressive decline of CD4+ T-cell numbers and increase in viral load. To keep the virus replication in check, patients need to take the antiretroviral therapy life-long, which is not without gastrointestinal discomfort. Probiotics have already shown multiple benefits ranging from reduction in diarrhea, nausea and bloating besides replenishment of CD4+ T-cells numbers. Based on this background information, we have compiled the data on probiotics among HIV-infected children. A pooled analysis from randomized clinical trials revealed significant improvement in CD4+ T-cell counts in HIV-infected children without any adverse effects. However, we recommend large and well-designed trials in future that would help in forming a concrete and high quality evidence in this context.
