Tuberculosis is the leading cause of death among people with HIV, so better integrating care for the two diseases is seen as crucial to ending TB.
For people living with HIV, tuberculosis is a big problem. It is the leading cause of death among those with HIV, who are 14 to 18 times more likely to fall ill with the disease than those without HIV, according to the World Health Organization. Latent TB infections can more easily progress to full disease due to the weakened immune system of people with HIV. Around 1 in 3 AIDS-related deaths in 2021 were also due to TB.
The dual risk has been on the global health community’s mind in recent decades, with acknowledgment that the two diseases need to be tackled together: The provision of antiretroviral therapy, or ART, to people living with HIV and diagnosed with TB averted an estimated 74 million deaths between 2000 and 2021.
Missing diagnoses
“One hundred percent, the two diseases have to be in people’s heads together,” said Helen Bygrave, a chronic disease adviser at Médecins Sans Frontières who focuses on sub-Saharan Africa. “The integration of services has been a key element programmatically for MSF’s work. The idea is to make sure everybody we’re diagnosing with HIV is properly screened for TB and, likewise, anybody diagnosed with TB is tested for HIV and then appropriately started on ART.”
Having these facilities in the same place is crucial, said Bygrave, adding that this has improved over time. “Before we integrated care, what we saw is that people would just get lost in the system,” she said. “That happens as soon as you have to refer somebody to another clinic room, another building or a different hospital.”
But despite these efforts, almost half of people with HIV who developed TB in 2021 were not diagnosed or reported to have TB, while coverage of TB preventive therapy, or TPT, among eligible HIV-positive people stands at only 42%.
Meanwhile, last year, MSF highlighted concerning signs of a reversal in progress in combating the two diseases, compounded by COVID-19 and global economic difficulties. Even before the pandemic, the organization had identified a crucial funding gap for HIV and TB response.
“There’s full recognition of the dual issue by donors, but implementation could still be better,” said Bygrave. “Investment in treatment literacy needs funding too, with counseling in the clinic and education about people’s diseases being areas of care that can always be done better.”
