764. Impact of Diabetes Mellitus on the Presentation and Response to Treatment of Adults With Pulmonary Tuberculosis in Qatar

BACKGROUND: Persons with diabetes mellitus (DM) have a 3-fold increased risk of TB. Vitamin D deficiency also is associated with a 4-fold increase in risk of progression of TB from latent TB infection to active TB. Qatar is an oil rich country with high prevalence of diabetes, obesity, and vitamin D deficiency. We aimed to evaluate the effect of diabetes mellitus on manifestations and response to treatment in adults with DM and TB. METHODS: Retrospective national hospital-based study of adult from January 2007 to December 2011, comparing TB-infected patients with and without DM. RESULTS: Of 134 adults with DM and TB, 62 (47%) became culture negative after 8 weeks of anti-TB treatment compared with 84 (72%) patients without DM. Patients with DM had more frequent lower lobe disease (28% vs. 17%, P = 0.03). Week 8 sputum culture conversion did not differ between patients by the degree of dysglyemia at time of diagnosis and onset of anti-TB treatment (70% vs. 46%, P = 0.09). CONCLUSION: Diabetes mellitus was associated with delayed sputum culture conversion at two month and atypical radiological findings in adults with pulmonary TB in Qatar. Glycemic control had no effect on week-8 sputum culture conversion. DISCLOSURES: All authors: No reported disclosures.
