Abstract
BACKGROUND
Both tuberculosis (TB) and diabetes mellitus (DM) are major public health problems threatening global health. TB patients with DM have a higher bacterial burden and affect the absorption and metabolism for anti-TB drugs. Drug-resistant TB (DR-TB) with DM make control TB more difficult.
METHODS
This study was completed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline. We searched PubMed, Excerpta Medica Database (EMBASE), Web of Science, ScienceDirect and Cochrance Library for literature published in English until July 2022. Papers were limited to those reporting the association between DM and treatment outcomes among DR-TB and multidrug-resistant TB (MDR-TB) patients. The strength of association was presented as odds ratios (ORs) and their 95% confidence intervals (CIs) using the fixed-effects or random-effects models. This study was registered with PROSPERO, number CRD: 42,022,350,214.
RESULTS
A total of twenty-five studies involving 16,905 DR-TB participants were included in the meta-analysis, of which 10,124 (59.89%) participants were MDR-TB patients, and 1,952 (11.54%) had DM history. In DR-TB patients, the pooled OR was 1.56 (95% CI: 1.24-1.96) for unsuccessful outcomes, 0.64 (95% CI: 0.44-0.94) for cured treatment outcomes, 0.63 (95% CI: 0.46-0.86) for completed treatment outcomes, and 1.28 (95% CI: 1.03-1.58) for treatment failure. Among MDR-TB patients, the pooled OR was 1.57 (95% CI: 1.20-2.04) for unsuccessful treatment outcomes, 0.55 (95% CI: 0.35-0.87) for cured treatment outcomes, 0.66 (95% CI: 0.46-0.93) for treatment completed treatment outcomes and 1.37 (95% CI: 1.08-1.75) for treatment failure.
CONCLUSION
DM is a risk factor for adverse outcomes of DR-TB or MDR-TB patients. Controlling hyperglycemia may contribute to the favorite prognosis of TB. Our findings support the importance for diagnosing DM in DR-TB /MDR-TB, and it is needed to control glucose and therapeutic monitoring during the treatment of DR-TB /MDR-TB patients.
