Insights
Chronic hepatitis B (CHB) increases mortality risk in people with HIV and high viral loads. CHB also complicates antiretroviral therapy (ART) management, leading to more treatment changes.
Area of Science:
- Infectious Diseases
- Hepatology
- Virology
Background:
- People living with HIV (PLWHIV) often have co-infections, including chronic hepatitis B (CHB).
- Antiretroviral therapy (ART) is crucial for managing HIV but its interaction with CHB requires further investigation.
Purpose of the Study:
- To evaluate the impact of CHB on survival and ART complexity in PLWHIV.
- To determine if HBV DNA levels influence mortality risk in coinfected individuals.
Main Methods:
- A cohort of PLWHIV in South Africa was assessed for mortality and ART modifications.
- Patients were categorized based on the presence and hepatitis B virus (HBV) DNA levels of CHB.
- Follow-up extended up to 3 years post-ART initiation.
Main Results:
- Mortality was significantly higher in CHB patients with HBV DNA > 10,000 copies/mL.
- No increased mortality was observed in CHB patients with HBV DNA < 10,000 copies/mL compared to non-CHB patients.
- Coinfected patients experienced more single-drug substitutions, irrespective of HBV DNA levels.
Conclusions:
- CHB is associated with increased mortality risk in PLWHIV, particularly with high viral loads.
- CHB complicates ART management, necessitating more frequent treatment adjustments.
Objectives:
To assess the effect of chronic hepatitis B on survival and clinical complexity among people living with HIV following antiretroviral therapy (ART) initiation.
Methods:
We evaluated mortality and single-drug substitutions up to 3 years from ART initiation (median follow-up 2.75 years; interquartile range 2-3 years) among patients with and without chronic hepatitis B (CHB) enrolled in a workplace HIV care programme in South Africa.
Results:
Mortality was increased for CHB patients with hepatitis B virus (HBV) DNA levels > 10 000 copies/mL (adjusted hazard ratio 3.1; 95% confidence interval 1.2-8.0) compared with non-CHB patients. We did not observe a similar difference between non-CHB patients and those with CHB and HBV DNA < 10 000 copies/mL (adjusted hazard ratio 0.70; 95% confidence interval 0.2-2.3). Single-drug substitutions occurred more frequently among coinfected patients regardless of HBV DNA level.
Conclusions:
Our findings suggest that CHB may increase mortality and complicate ART management.

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.
