Diabetes mellitus (DM) seems to occur in correlation with tuberculosis, having a serious impact on the care of patients suffering from TB. The primary research objective is to estimate the prevalence of diabetes mellitus in new patients with active pulmonary tuberculosis. The next step will be to evaluate the treatment of TB in its different phases in diabetic patients. We will thereby seek to assess the clinical presentation of tuberculosis in diabetic patients, comparing them to non-diabetic patients and noting complications caused by DM in patients with TB.
