Life expectancy decline in people with treated tuberculosis and the possible benefits of prophylaxis

Abstract

Background: Evidence of significant, measurable, and preventable loads of mortality risk even after anti-tuberculosis therapy and cure would be a convincing, tangible, and meaningful indicator of the efficacy of prevention. Aims & Objectives: To study of a life expectancy decline in people with treated tuberculosis and the possible benefits of prophylaxis Methods & Materials: We examined the years of potential life lost between 918 people with latent tuberculous infection and a cohort of 386 cured tuberculosis (TB) patients. To estimate the anticipated years of potential life lost for each cohort and for demographic groupings, we built a regression model. Results: When compared to a group without active TB, decedents with a history of thoroughly treated TB are anticipated to lose an additional 3.6 years of life on average. White and Hispanic people were expected to see greater longevity losses than their Black and Asian counterparts. Conclusion: The expected lifetime of treated TB survivors was significantly different from that of a comparable group without active TB, according to our research. With a total of 1485 lifeyears lost, or the equivalent of more than 180 75-year lifespans, these excess losses are considerable. These results highlight an important lost opportunity cost for each TB case that could have been prevented: an average of 3.6 years of life. We come to the conclusion that despite adequate anti-tuberculosis treatment, there is still a significant burden of preventable mortality, which is a strong argument in favour of more widespread and organised use of prevention.
