Qualitative systematic review of homeopathic outcome studies in patients with HIV/AIDS

Abstract

Background and aims: Systematic reviews of high-quality randomized controlled trials (RCTs) are crucial in evidence-based medicine (EBM). The aim of the present review was to investigate whether there is enough evidence on the efficacy of homeopathy in individuals with HIV/AIDS based on clinical trials. Methods: The present is a criteria-based systematic review of cumulative research, and assessment of the methodological quality of published studies. The quality of the trials was evaluated using a list of validated and predefined criteria, and their outcomes were interpreted based on their quality. The main outcome measure was the methodological quality of the studies in terms of the threats to external, internal, construct, and statistical conclusion validity. Results: Among the 6 clinical outcome studies located, 3 were open-label, non-randomized, non-controlled trials, 2 were RCTs, and one was a single-set replication study. The trials were too few in number, and did not exhibit very high quality. The results showed a positive trend regardless of the quality of the trials, or the variety of homeopathic treatment used. The results of the present review may be complicated by publication bias. Conclusion: The currently available evidences do not suffice to infer definitive conclusions. Therefore, further evaluation of homeopathic treatment by means of appropriate RCTs with high methodological quality is required.
