Co-infection With Hepatitis B in Tuberculosis Patients on Anti-tuberculosis Treatment and the Final Outcome.

Background The occurrence of both tuberculosis (TB) and concomitant hepatitis B virus (HBV) is likely to be associated with poor patient outcomes and poor treatment response. Objective To assess whether tuberculosis patients with concomitant hepatitis B virus infection were prone to poorer outcomes and treatment response. Methodology A case-control study was undertaken at the Tuberculosis Centre, DHQ Bagh Azad Kashmir and Pulmonology Department, Lady Reading Hospital, Peshawar, between March 2020 and August 2020. All patients with diagnosed tuberculosis and coinfection with hepatitis B were labeled as the case group while those with only tuberculosis acted as the control. All patients with tuberculosis were managed on a directly observed treatment strategy (DOTS). Non-compliant patients and those without complete data were excluded from the study. All data regarding socio-demographics, laboratory investigations, and clinical characteristics were recorded in a predefined proforma. Patients were considered to have good treatment outcomes when patients completed the treatment or had a negative smear at six months of treatment. The Statistical Package for the Social Sciences (SPSS) version 26 (IBM Corp, Armonk, NY) was used for the data analysis. Results A total of 178 patients were enrolled in the study. It was found that patients with concomitant hepatitis B had significantly poorer outcomes as compared to patients who did not have hepatitis B (<0.001). Similarly, TB and hepatitis B patients were significantly associated with severe tuberculosis (<0.001) and required a higher frequency of retreatment (<0.001). Conclusion Our study reports a strong association between the treatment response of patients with tuberculosis with an added hepatitis B infection. Furthermore, a larger number of patients with hepatitis B had severe tuberculosis as compared to those without hepatitis B.
