Oral candidiasis prevalence in human immunodeficiency virus-1 and pulmonary tuberculosis coinfection: A systematic review and meta-analysis

Abstract

Background: Human immunodeficiency virus-1 (HIV-1) infected people are more likely to develop tuberculosis (TB), being the leading cause of death in HIV-1. Candida spp has emerged as potential pathogenic fungi in patients with HIV and bronchopulmonary diseases. This systematic review summarizes the available data on the occurrence of oral candidiasis (OC) in the HIV-1/pulmonary tuberculosis (pTB) coinfection.

Methods: Articles that reported the occurrence of OC in the HIV-1-pTB coinfection were searched in eight databases. Observational studies that evaluated the association between OC and HIV-1-pTB coinfection were selected. The risk of bias was assessed using the meta-analysis of statistics assessment and review instrument (MAStARI) checklist.

Results: From a total of 1858 records, after application of inclusion and exclusion criteria, six were included in the meta-analysis. Three studies were at low risk, one at moderate risk, and two at high risk of bias. Considerable heterogeneity across the studies was identified. Meta-analyses performed showed no difference in the prevalence of OC between HIV-1 patients with and without pTB coinfection (odds ratio M-H = 1.77; 95% CI = 0.69 to 4.52).

Conclusion: There is no association between OC and HIV-1/pTB coinfection.
