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.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.
Mode of...

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
