Summary
The human immunodeficiency virus (HIV) epidemic fuels tuberculosis (TB) spread globally. HIV impairs immunity, increasing TB risk, atypical presentations, and drug resistance, making TB a leading cause of death in HIV patients.
Area of Science:
- Public Health
- Infectious Diseases
- Immunology
Background:
- The co-epidemic of tuberculosis (TB) and human immunodeficiency virus (HIV) has been recognized since the emergence of HIV.
- HIV spread significantly contributes to the global increase in TB incidence.
- Impaired cell-mediated immunity due to HIV alters TB pathogenesis and elevates risk in co-infected individuals.
Purpose of the Study:
- To elucidate the impact of HIV on tuberculosis incidence, pathogenesis, and outcomes.
- To highlight the role of HIV in the increased risk of multidrug-resistant TB.
- To underscore TB as a critical opportunistic infection and cause of mortality in HIV-positive populations.
Main Methods:
- Review of epidemiological data on TB and HIV co-infection.
- Analysis of the immunological mechanisms linking HIV and TB pathogenesis.
- Examination of clinical and radiological presentation differences in HIV-positive TB patients.
Main Results:
- HIV infection markedly increases the risk of developing TB.
- HIV-associated immunosuppression leads to more extrapulmonary TB and atypical radiological findings.
- HIV is a significant factor in the rise of multidrug-resistant *Mycobacterium tuberculosis*.
Conclusions:
- Tuberculosis is the most common opportunistic infection and a leading cause of death globally in HIV-infected individuals.
- Despite treatment and prevention options, TB continues to spread in the HIV-positive population.
- Effective management of the HIV-TB co-epidemic is crucial for global public health.
