RESUMO

Tuberculosis (TB) is the leading cause of death among persons with HIV. In 2022, an estimated 167,000 TB-related deaths occurred globally among persons with HIV. TB preventive treatment (TPT) helps prevent TB disease and is recommended for persons at high risk for developing TB, including those with HIV. TPT, when taken with antiretroviral treatment (ART), can reduce TB-attributable deaths among persons with HIV. In 2018, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) program committed to offer one course of TPT to all eligible clients receiving ART. This analysis describes trends in TPT initiation and completion among PEPFAR-supported programs in 36 countries in Africa, Central and South America, and Asia during fiscal years (FYs) 2017-2023. Overall, TPT initiation rates peaked in FY19, a possible sign of programmatic saturation. TPT initiation among clients who had been on ART <6 months reached 59%, and overall completion rates up to 87% were reported. Approximately 13 million persons with HIV have completed TPT since FY17, but widespread adoption of shorter regimens, patient-centered approaches, and electronic medical record systems might be needed to ensure full TPT coverage. Through PEPFAR's partnership with national HIV programs, TPT has become the standard of care for persons with HIV.

RESUMO

The intersection of tuberculosis (TB) and human immunodeficiency virus (HIV) infection has eroded gains made in TB control, because previously well-functioning national TB programs have been overwhelmed by the dual challenges posed by TB and HIV coinfection. The US President's Emergency Plan for AIDS Relief (PEPFAR), through its direct support of >2.4 million persons receiving HIV treatment and, in 2009, support of >308,000 HIV-infected persons receiving TB treatment, works closely with national governments and other partners to strengthen the response to TB and HIV coinfection. PEPFAR-supported activities fall within the World Health Organization's 2004 framework for collaborative TB and HIV activities, including critical interventions to (1) develop organizational methods of collaboration across the 2 programs, (2) reduce the burden of HIV infection among patients with TB, and (3) reduce the burden of TB among persons with HIV infection or AIDS. To date, PEPFAR and partners have made important gains in coverage and scope of HIV testing, referral, and antiretroviral therapy for patients with TB. TB screening of HIV-infected patients is also beginning to increase, although greater progress needs to be made in increasing access to isoniazid preventive therapy and strengthening TB infection control. Continued strategic integration of TB and HIV interventions into PEPFAR-supported programs is essential to easing the patient burden of dual infection, improving patient outcomes, and, ultimately, decreasing rates of TB in areas with a high prevalence of TB.

RESUMO

BACKGROUND: To eliminate preventable deaths, disease and suffering due to tuberculosis (TB), improved diagnostic capacity is critical. The Cepheid Xpert® MTB/RIF assay is recommended by the World Health Organization as the initial diagnostic test for people with suspected HIV-associated TB. However, despite high expectations, its scale-up in real-world settings has faced challenges, often due to the systems that support it. OPPORTUNITIES FOR SYSTEM STRENGTHENING: In this commentary we discuss needs and opportunities for systems strengthening to support widespread scale-up of Xpert® MTB/RIF as they relate to each step within the TB diagnostic cascade, from finding presumptive patients, to collecting, transporting and testing sputum specimens, to reporting and receiving results, to initiating and monitoring treatment and, ultimately, to ensuring successful and timely treatment and cure. Investments in evidence-based interventions at each step along the cascade and within the system as a whole will augment not only the utility of Xpert® MTB/RIF, but also the successful implementation of future diagnostic tests. CONCLUSION: Xpert® MTB/RIF will only improve patient outcomes if optimally implemented within the context of strong TB programs and systems. Roll-out of this technology to people living with HIV and others in resource-limited settings offers the opportunity to leverage current TB and HIV laboratory, diagnostic and programmatic investments, while also addressing challenges and strengthening coordination between laboratory systems, laboratory-program interfaces, and TB-HIV program interfaces. If successful, the benefits of this tool could extend beyond progress towards global End TB Strategy goals, to improve system-wide capacity for global disease detection and control.

RESUMO

Xpert MTB/RIF is a major advance for TB diagnostics, especially for multidrug-resistant (MDR) TB and HIV-associated TB. But implementation concerns including cost, technical support requirements, and challenging demands of providing second-line TB drugs for diagnosed MDR-TB cases call for gradual, careful introduction based on country circumstances.

RESUMO

The US President's Emergency Plan for AIDS Relief (PEPFAR) has supported a comprehensive package of care in which interventions to address HIV-related tuberculosis (TB) have received increased funding and support in recent years. PEPFAR's TB/HIV programming is based on the World Health Organization's 12-point policy for collaborative TB/HIV activities, which are integrated into PEPFAR annual guidance. PEPFAR implementing partners have provided crucial support to TB/HIV collaboration, and as a result, PEPFAR-supported countries in sub-Saharan Africa have made significant gains in HIV testing and counseling of TB patients and linkages to HIV care and treatment, intensified TB case finding, and TB infection control. PEPFAR's support of TB/HIV integration has also included significant investment in health systems, including improved laboratory services and educating and enlarging the workforce. The scale-up of antiretroviral therapy along with support of programs to increase HIV counseling and testing and improve linkage and retention in HIV care may have considerable impact on TB morbidity and mortality, if used synergistically with isoniazid preventive therapy, intensified case finding, and infection control. Issues to be addressed by future programming include accelerating implementation of isoniazid preventive therapy, increasing access and ensuring appropriate use of new TB diagnostics, supporting early initiation of antiretroviral therapy for HIV-infected TB patients, and strengthening systems to monitor and evaluate program implementation.
