Background:
While patients with hepatitis B virus (HBV) infection and tuberculosis (TB) have similar risk factors, little is known regarding the prevalence of HBV and TB coinfection. We aim to evaluate the prevalence of HBV among patients with TB across world regions.
Methods:
We systematically reviewed the literature using PubMed from inception through September 1, 2019, to identify studies that provided data to calculate HBV coinfection prevalence among adults with TB infection. Prevalence estimates of HBV coinfection among TB patients were stratified by world regions and calculated using meta-analyses with random-effects models.
Results:
A total of 36 studies met inclusion criteria (4 from the Africa region, 6 from the Americas region, 5 from the Eastern Mediterranean region, 2 from European region, 6 from Southeast Asia region, and 13 from the Western Pacific region). On meta-analysis, overall pooled HBV coinfection prevalence among TB patients was 7.1%, but varied by world region. Region-specific pooled HBV prevalence among TB patients was highest in Africa region [11.4%, 95% confidence interval (CI): 3.45-19.31] and Western Pacific region (10.8%, 95% CI: 8.68-12.84), and was lowest in the Americas (2.2%, 95% CI: 0.78-3.53). Sensitivity analyses yielded similar HBV prevalence estimates across world regions.
Conclusions:
In this meta-analysis, we observed HBV coinfection prevalence among TB patients to be 38% to 450% higher than published estimates from the Polaris group of region-specific overall HBV prevalence. Timely identification of HBV infection among TB patients will improve patient outcomes by allowing for closer clinical monitoring and management, which may reduce the risk of liver dysfunction and liver failure related to TB treatment.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
