Understanding the Crucial Link Between Tuberculosis and HIV: What You Need to Know

Tuberculosis (TB) remains a leading cause of mortality among individuals living with HIV. The HIV virus weakens the immune system, making it significantly harder for the body to combat bacterial infections like TB.

People residing in regions with high TB prevalence face an elevated risk, but anyone with HIV is inherently more susceptible to TB infection. Early detection through regular screening is critical, as timely and appropriate treatment can cure TB in people living with HIV. Treatment plans are tailored based on the type of infection and the antiretroviral medications a patient is using.

Coinfection: When HIV and Tuberculosis Occur Together

Coinfection refers to having both HIV and TB simultaneously. TB infections may be active, causing symptoms, or latent, where bacteria remain dormant without causing illness.

Latent TB means the bacteria are present but inactive, often controlled by a healthy immune system for years or even a lifetime. However, HIV compromises immune defenses, enabling latent TB to reactivate into an active, potentially deadly infection. Moreover, TB can accelerate the progression of HIV.

Globally, TB is a top cause of death among people with HIV. Coinfected individuals face twice the mortality risk compared to those with TB alone. High-risk populations include those in countries with widespread TB like India and South Africa, as well as individuals living in overcrowded environments or incarceration.

Drug-resistant forms of TB, including multi-drug-resistant (MDR-TB) and extensively drug-resistant TB (XDR-TB), pose additional challenges, particularly in regions such as Ukraine, Russia, South-East Asia, and South Africa, where HIV prevalence is also significant.

Is Tuberculosis a Symptom of HIV?

TB itself is not a direct symptom of HIV; however, HIV can trigger latent TB to become active. Individuals with robust immune systems may harbor latent TB without ever developing symptoms, but HIV-induced immune suppression increases the risk of life-threatening active TB.

Testing Recommendations for People with HIV

The U.S. Centers for Disease Control and Prevention (CDC) advises that anyone diagnosed with TB or at risk for TB also undergo HIV testing. Rapid HIV tests provide results in approximately 20 minutes.

Similarly, individuals at high risk for TB should be tested regularly. High-risk groups include those living or working in correctional facilities, long-term care centers, homeless shelters, healthcare workers, children exposed to high-risk adults, residents of TB-endemic countries, symptomatic individuals, and people living with HIV.

Annual TB screening is generally recommended for these groups. Testing methods include sputum smear and culture or advanced molecular tests like GeneXpert, which are safe and effective for people with HIV. Molecular tests offer faster and more accurate diagnosis, including detection of drug-resistant TB strains, often supplemented by chest X-rays and urine analysis.

Guidelines for Treating HIV and Tuberculosis Coinfection

Treatment varies based on whether TB is latent or active. For latent TB, options include:

• Daily rifampin for 4 months, though it may interact with certain antiretroviral and contraceptive medications.
• Weekly rifapentine for 12 weeks, a newer FDA-approved regimen.
• Daily isoniazid for 9 months, commonly used when rifampin or rifapentine are unsuitable.

Active TB treatment typically involves:

• High-dose daily rifapentine combined with moxifloxacin, isoniazid, and pyrazinamide for 4 months, with dosing adjusted over time.
• Moderate doses of rifampin, moxifloxacin, isoniazid, and pyrazinamide for 6 to 9 months.
• Extended treatment up to 2 years for drug-resistant TB, often requiring multiple antibiotics and specialist care.

Insights from Recent Research on HIV and TB

Studies highlight the complex interplay between HIV and TB, emphasizing the need for enhanced education, prevention strategies, and further investigation. Increased TB risk has been noted among:

• People with HIV over 40 years old.
• Individuals living in South-East Asia.
• Those assigned male at birth with HIV.
• Recently diagnosed HIV patients.
• People in prisons or overcrowded housing.

Is Tuberculosis Curable in People with HIV?

Absolutely. TB can be effectively cured in individuals living with HIV, provided timely diagnosis and treatment initiation occur. Without treatment, TB can rapidly worsen health and lead to death, but most people with HIV respond well to TB therapy.

Support and Resources for Living with HIV

Managing HIV can be challenging, but numerous resources offer community and assistance:

• POZ Community Forums: An interactive platform for sharing experiences and support among people living with HIV.
• The Well Project: Focused support and forums for women and girls with HIV.
• Positive Peers: A mobile app connecting young people aged 13-34 living with HIV.
• Thrive SS: Support network for Black gay and bisexual men with HIV, including mental health services.
• Ryan White HIV/AIDS Program: Provides medical care assistance based on income eligibility.
• Housing Opportunities for Persons With AIDS (HOPWA): Federal housing assistance for people living with HIV/AIDS and their families.

Key Takeaway

Individuals with HIV face a heightened risk of contracting TB due to immune system impairment, which can activate latent infections into dangerous active disease. Early and regular testing, ideally annually, is crucial to identify TB promptly.

Effective treatment options exist for both latent and active TB in people with HIV, with durations ranging from a few months to several years depending on drug resistance and individual response. Awareness, prevention, and access to care remain essential components in managing this dual health challenge.
