Insights
In Brazil, 7.5% of tuberculosis patients had hepatitis C virus (HCV) infection, with age, drug use, and HIV status as key risk factors. Integrated HIV and HCV screening can improve tuberculosis management.
Area of Science:
- Infectious Diseases
- Public Health
- Virology
Background:
- Tuberculosis (TB) and viral infections like hepatitis C virus (HCV) and human immunodeficiency virus (HIV) often coexist.
- Understanding the prevalence and risk factors of HCV and HIV in TB patients is crucial for effective public health strategies.
Purpose of the Study:
- To determine the prevalence of HCV infection, associated risk factors, HCV genotypes/subtypes, viral load, and HIV status among tuberculosis patients in Central Brazil.
- To assess the potential benefits of integrated HIV and HCV screening in TB patient management.
Main Methods:
- A cross-sectional study was conducted with 402 patients undergoing tuberculosis treatment in Goiânia, Brazil.
- Data collected included HCV and HIV prevalence, risk factors (age, injecting drug use), HCV RNA levels, and HCV genotyping (LiPA and phylogenetic analysis).
Main Results:
- Hepatitis C virus (HCV) prevalence was 7.5% and human immunodeficiency virus (HIV) prevalence was 27.6%.
- Injecting drug use, age, and HIV status were independently associated with HCV infection. Two-thirds of HCV-infected patients were also HIV-positive.
- HCV genotypes 1 and 3 were identified, with subtypes 1a, 1b, and 3a detected. HCV RNA levels were slightly higher in co-infected patients.
Conclusions:
- Integrated screening for HIV and HCV in tuberculosis patients is recommended.
- Such screening can significantly impact tuberculosis management and treatment outcomes.
Setting:
Goiânia City, Goiás State, Brazil.
Objectives:
To determine the prevalence of hepatitis C virus (HCV) infection, risk factors, HCV genotype/ subtype, HCV viral load and human immunodeficiency virus (HIV) status in patients with tuberculosis (TB) in Central Brazil.
Design:
A cross-sectional study was carried out with 402 patients who were under tuberculosis (TB) treatment in the reference hospital for infectious diseases in Goiânia, Goiás, Central Brazil.
Results:
The prevalence rates of HCV and HIV were respectively 7.5% and 27.6%. Two thirds of the HCV-infected patients (20/30) were HIV-positive. Age, injecting drug use (IDU) and HIV status were factors independently associated with HCV infection. HCV RNA was detected in 23 serum samples; HCV RNA levels were measured in 22/23 samples. HCV RNA level was slightly higher in HCV-HIV co-infected patients than in HCV monoinfected patients. Genotypes 1 (n = 17) and 3 (n = 6) were determined by LiPA. Using phylogenetic tree analysis of the NS5B region, subtypes 1a (n = 12), 1b (n = 2) and 3a (n = 6) were identified.
Conclusion:
These data indicate that patients with TB may benefit from integrated HIV and HCV screening, which may have an important impact upon TB management and treatment.

Pulmonary Tuberculosis I
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.
