Background: Chronic obstructive pulmonary disease (COPD) is a
preventable and treatable disease characterized by shortness of breath and
cough. Diabetes mellitus (DM) is a chronic metabolic disease characterized by
deficiency or diminished effectiveness of endogenous insulin resulting in
hyperglycaemia, deranged metabolism and different complications.

Objective: The objective of this study to determine the frequency of newly
diagnosed diabetes mellitus in patients with pulmonary tuberculosis.
Methodology: This cross-sectional study was conducted in the
Pulmonology wards/OPD's of Khyber Teaching Hospital Peshawar from
17/06/2017 to 16/12/2017. A total of 117 patients were included in the study
using 12.4% proportions of newly diagnosed DM in patients with pulmonary
tuberculosis, 95% confidence interval and 6% margin of error under WHO
software for sample size determination. All patients with newly diagnosed
pulmonary tuberculosis irrespective of sputum smear positivity were included
in the study. Patients already diagnosed as diabetes mellitus and those with
extra-pulmonary tuberculosis were excluded from the study.

Results: Out of 117 patients, 56.4% (n = 66) were females and 43.6% (n = 51) were males. The mean age of the study population was 37.03 (SD+18.610)
years. The frequency of diabetes mellitus in patients with pulmonary
tuberculosis was 16.2%.

Conclusions: There is an increased frequency of diabetes mellitus in
patients with pulmonary tuberculosis.
