“The findings our trial support the use of urine-based TB screening, and we hope to change how we screen for TB in HIV-positive admissions in the hospital in places with high burden of HIV and TB,” he said, speaking on behalf of colleagues in the STAMP Study.
HIV-related TB caused an estimated 400,000 deaths worldwide in 2016, and is responsible for between 32% and 67% of deaths in HIV-positive adults admit to hospitals in Africa. Yet half of all of those cases of TB are undiagnosed at the time of death, he said.
Urine based screens are easily obtained and have good diagnostic yield for disseminated TB, which is common in patients with advanced HIV, he said.
To see whether adding urine screening could increase TB diagnosis and treatment and reduce TB deaths among hospitalized HIV+ patients, the investigators enrolled 2,600 unselected HIV+ adults admitted to hospitals in South Africa and Malawi. Patients less than 18 years of age, those who had been treated for TB with the last 12 months or had received TB prophylaxis with isoniazid within the last 6 months were excluded, leaving a sample size of 2,574.
