RESUMO
The burden of tuberculosis (TB) is disproportionate in tropical and subtropical regions, where parasitic coinfections are common. Given the significant geographical overlap between TB and intestinal parasitic infections, it is important to consider the implications of intestinal parasitic infections for the TB pandemic. Intestinal parasitic infections have been theorized to increase vulnerability to TB by altering the inflammatory milieu, inducing undernutrition that blunts the immune response, and affecting drug pharmacokinetics. In this perspective, we provide a background of the epidemiological and immunological evidence that links parasitic infections to increased risk of TB progression and worse treatment outcomes. We also identify gaps in our knowledge and call for increased research on TB-parasitic coinfections to ensure action on a potentially widespread TB comorbidity.
