RESUMO
The double burden of tuberculosis (TB) and diabetes mellitus (DM) represents a major public health challenge that demands urgent and integrated approaches. The interplay between these two chronic conditions presents unique clinical and public health management challenges, as well as social and economic implications. We explored the bidirectional relationship between TB and DM, emphasizing how DM increases susceptibility to TB and complicates its management, while TB may exacerbate glycaemic control in diabetic patients. This review underscores the challenges associated with the management of both diseases, obstacles in screening TB patients for DM and TB preventive therapy for DM since inadequate glycaemic control can impact treatment outcomes. Several studies have investigated the disease interplay; however, the results have been equivocal, and this may be exerting negative impacts on the disease prevention and treatment. TB-diabetes comorbidity has been linked to poor treatment outcomes whereas TB prevention in people with DM at present is a dilemma. In addition to highlighting how urgent it is to address this comorbidity, this review offers a road map for better prevention, treatment, and control of several factors underlying the TB-diabetes syndemic interaction.
