A Study of the Patients Suffering from Tuberculosis and Tuberculosis-diabetes Comorbidity in Revised National Tuberculosis Control Program Centers of Northern Madhya Pradesh, India.

BACKGROUND

Diabetes mellitus (DM) is recognized as an important risk factor to tuberculosis (TB). India has high TB burden, along with rising DM prevalence.

AIM

This study was conducted to document the coexistence of DM and TB in persons with established TB under the Revised National Tuberculosis Control Program.

TYPE OF STUDY

This was a cross-sectional, descriptive observational study conducted at selected Directly Observed Therapy center in Gwalior North Central India.

MATERIALS AND METHODS

A total of 550 patients with confirmed diagnosis of TB and on treatment were recruited. The study participants were screened for DM and diagnoses were made on the basis of the World Health Organization criteria. Clinical parameters were compared between persons with DM and those without DM.

RESULTS

DM/TB co-morbidity was noted in 85 individuals and these made up 15.4% of the study population. The mean age was higher in DM patients with TB (43.4 ± 15.4 vs. 33.1 ± 16.2 years, = 0.000); the mean duration of symptoms of TB with DM was more (124 ± 16.4 vs. 107.49 ± 10.3 days). Multinomial logistic regression analysis showed that increasing age, positive family history of diabetes, sedentary occupation, and presence of pulmonary TB were significantly associated with diabetes among TB patients.

CONCLUSIONS

Diabetes is an important co-morbid feature to be sought in patients with TB. This study re-echo the need to raise awareness on screening for DM in persons with TB.
