Tuberculosis with human immunodeficiency virus infection

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Background:

• Tuberculosis (TB) is the most frequent opportunistic infection in individuals with human immunodeficiency virus (HIV), particularly in developing nations like India.
• The co-occurrence of HIV and TB is rising in India, with children facing elevated risks due to infection or exposure.
• Clinical presentations of TB in HIV patients are generally similar to HIV-uninfected individuals, barring cases with severe immunodeficiency.

Purpose of the Study:

• To highlight the significance of tuberculosis as an opportunistic infection in HIV-infected individuals in India.
• To discuss the increasing seroprevalence of HIV among TB patients and the associated risks for children.
• To evaluate the effectiveness of standard chemotherapy and preventive measures for TB in the context of HIV co-infection.

Main Methods:

• Review of existing literature and epidemiological data on HIV and TB co-infection in India.
• Analysis of clinical and radiological manifestations of TB in HIV-infected versus HIV-uninfected populations.
• Assessment of treatment outcomes, including response to chemotherapy and mortality rates.
• Evaluation of the efficacy of preventive isoniazid therapy for latent TB infection.

Main Results:

• Tuberculosis is the most common opportunistic infection in HIV-positive patients in India, with increasing HIV seroprevalence among TB patients.
• HIV-infected children and children born to HIV-positive parents face a heightened risk of TB.
• While standard chemotherapy is often effective, mortality remains high due to concurrent opportunistic infections.
• Preventive treatment with isoniazid for 6-12 months demonstrates effectiveness in managing latent TB infection.

Conclusions:

• HIV-TB co-infection poses a significant public health challenge in India, necessitating integrated management strategies.
• Early diagnosis and effective management, including preventive therapy, are crucial for reducing morbidity and mortality in HIV-TB patients, especially children.
• Continued surveillance and research are essential to combat the growing burden of TB in the HIV-infected population.
