Magnitude and Associated Factors of Pulmonary Tuberculosis Among HIV/AIDS Patients Attending Antiretroviral Therapy Clinic at Debre Tabor Specialized Hospital, Northwest Ethiopia, 2019

Prevalence of pulmonary tuberculosis and associated factors among adults living with HIV/AIDS attending public hospitals in Shashamene Town, Oromia Region, South Ethiopia

Objective:

This study was aimed to assess the prevalence of pulmonary tuberculosis and its associated factors among adults living with HIV/AIDS attending Public Hospitals, Shashamene Town, Oromia Region, South Ethiopia.

Methods:

A cross-sectional study was conducted from November 2020 to February 2021 among Adults Living with HIV/AIDS attending Public Hospitals in Shashamene Town, Oromia Region, South Ethiopia. A sputum sample was collected and analyzed using Xpert MTB/RIF assay and blood sample was collected to count CD4 using BD FACSPresto analyzer. Semi-structured questionnaires were used to collect data. SPSS version 25 software was used for statistical analysis and a p value of <0.05 was considered as statistically significant.

Results:

In this study, the overall prevalence of pulmonary tuberculosis among adults living with HIV/AIDS attending the Public Hospitals was 23.5% (5% confidence interval: 18.26, 29.13). Variables such as age range of 50–64 years, female gender, occupation with house wife, and World Health Organization stage (III and IV) were significantly associated with prevalence of tuberculosis infection.

Conclusion:

The prevalence of tuberculosis in our study site was high. There is a need for regular screening of people living with HIV/AIDS for TB using highly sensitive method like Xpert MTB/RIF assay to know their TB status as well as early commencement of anti-TB.

Active TB infection and its associated factors among HIV-1 infected patients at Jimma medical center, Southwest Ethiopia

Background

Human immune deficiency virus (HIV) increases the susceptibility to primary infection or reinfection and the risk of tuberculosis (TB) reactivation for patients with latent TB. There was no current report on the rate of active TB infection among HIV-1 infected patients in our teaching and referral hospital. Therefore, this study was aimed to determine the prevalence and factors associated with active TB infection among HIV-1 infected patients.

Methods

Hospital-based retrospective cross-sectional study was conducted at the Anti-Retroviral Therapy (ART) chronic follow-up clinic. Systematic random sampling was used to include the patients. A structured questionnaire was used to collect data. Data were analyzed using SPSS version 25. Descriptive statistics were used to describe the findings and multivariate logistic regression was performed to identify factors associated with active TB infection.

Result

150 HIV-1 infected patients (female 54.7%) were included. The median (interquartile range, IQR) age of the patients was 33.5 (25.7, 40.0) years. Twenty-six (17.3%) of the patients had developed active TB infection, which was independently associated with the WHO clinical stage III and IV (AOR: 9.67, 95% confidence interval (CI); 2.21–42.37), p = 0.003). The use of isoniazid preventive therapy (IPT) (AOR: 0.123, 95CI; 0.034–0.44, p = 0.001) and having good adherence to ART medications (AOR: 0.076, 95CI; 0.007–0.80, p = 0.032) was associated with the reduced risk of active TB infection among HIV-1 infected patients.

Conclusions

Advanced WHO clinical stages increased the risk of active TB infection, while the use of IPT and good adherence to ART medications reduced the risk of active TB infection. Therefore, patients with advanced WHO clinical stage should be screened for TB infection, and starting IPT for the candidate patients should be strengthened to reduce the burden of active TB incidence. ART medication adherence should also be supported.
