Abstract
Pulmonary tuberculosis is frequently associated with diabetes mellitus and, sometimes, it may present with atypical signs. The purpose of this study is to identify the epidemiological, clinical, biological and radiological features of pulmonary tuberculosis in patients with diabetes versus patients without diabetes in order to improve treatment. We conducted a retrospective, cross-sectional descriptive and analytical study in the Department of Endocrinology and Pneumology at the Joseph Raseta Befelatanana University Hospital Center and in the Department of Respiratory Diseases at the Soavinandriana Hospital Center in Antananarivo, Madagascar. It involved patients diagnosed with pulmonary tuberculosis who presented a positive bacilloscopy exam from January 2018 to January 2020 (25 months). In our study, the overall prevalence of diabetes among TB patients was 20.31 %. Older age, insidious clinical course, severe biologic inflammatory syndrome, fewer caves but more systematized opacities and diffuse radiological lesions in the basal zone (more commonly unilateral right lesions) were mainly detected in patients with diabetes compared to patients without diabetes. Knowledge of signs of pulmonary TB in patients with diabetes can help health care workers to make a diagnosis, even in patients with atypical signs. Moreover, as the majority of pulmonary tuberculosis occur in patients with unstable diabetes, a good glycemic balance can certainly reduce its incidence.
