TB symptom checks found only 22% of cases in diabetes study
Researchers from the University of Cape Town and University College London tested TB screening in 673 adults with diabetes in Khayelitsha. Symptom screening found 22% of TB cases and chest X-rays found 56%.
The study, led by senior author Professor Molebogeng Rangaka, appears in PLOS Global Public Health. Every participant also gave a sputum sample for molecular testing, which showed how many cases the other tools missed. Only nine of 661 valid results were positive for TB, so the estimates are uncertain. First author Dr Yohhei Hamada said larger studies are needed to confirm the findings.
