Influence of Micronutrient Consumption by Tuberculosis Patients on the Sputum Conversion Rate: A Systematic Review and Meta-analysis Study

Acta Med Indones. 2020 Apr;52(2):118-124.

Abstract

Background: infectious disease is one of the global health challenge in the world, including tuberculosis. Some factors significantly associated with increased treatment success, including the duration of treatment or treatment compliance, use more than three sensitive drugs, individualized regimen, and weight-related to micronutrient.

Methods: a systematic review and meta-analysis study of randomized control trial studies conducted and reported by preferred reporting items for systematic reviews and meta-analyses. The primary data source was online publications, consist of three bases data, which subscribed by Universitas Indonesia, they are Proquest, EBSCO CINAHL, EBSCO Dentistry. Risk of bias was assessed using the Cochrane risk-of-bias tool, and data were analyzed using Review Manager 2015.

Results: there were eight full paper rates as relevant studies. There was a significant difference of effect among the intervention group compared the control group (or placebo group). RR of the pooled estimate was 1.12 (95% CI: 1.06 - 1.18) with heterogeneity study 36%. While, the poled calculated based on type of micronutrient from seven studies showed there was no difference of sputum conversion between Vitamin D and placebo group (RR-1.05, 95% CI 0.99 - 1.12) with heterogeneity study 0% and a significant result seems among Zinc and Retinol intervention (RR=1.21, 95% CI 1.09 - 1.35) with heterogeneity study 40%.

Conclusion: micronutrient intervention during tuberculosis treatment has a positive effect toward to sputum conversion among patient. Zinc and retinol influence sputum conversion while vitamin D did not.
