Abstract: Background: The present study was done to study pneumonia in Type 2 Diabetic patients with respect to clinical and bacteriological profile, laboratory parameters and prognosis. Methods: It is a prospective observational study. Patients aged >18 Years with Type 2 Diabetes mellitus and who met the diagnostic criteria for pneumoniaas per British Thoracic Society guidelines, VAP is diagnosed in patients presenting with development of new or progressive radiological infiltrates after 48 hrs of admission or after 48 hrs of mechanical ventilation & one of the following - Fever >38.30C, Leucocytosis>12000/cu. mm, or Leucopenia <4000/cu. mm, Purulent respiratory secretion, Quantitative endotracheal aspirate cultures with growth > 106cfu/ ml. A total of fifty patients with Type 2 Diabetes and pneumoniain this study. Data were analysed using SPSS 21. A probability value of <0.05 has been considered as statistically significant. Conclusion: In CAP group the most common comorbidity observed was hypertension (44%) followed by cardiac failure (24%). In VAP group, next to poisoning (36%), the most common primary diagnosis in VAP group was cerebrovascular accident (28%) followed by renal disease (20%). Substance abuse such as smoking and alcoholism was found in 30% and 20% of the patients respectively. Klebsiella was the most common organism isolated from sputum culture in CAP group (56%) whereas in VAP group both klebsiella and pseudomonas were equally predominant (32% each). Mortality in CAP group was 12% and it was 36% in VAP group. Significant association between HbA1C level and blood urea with mortality was observed, HbA1c and blood urea were significantly higher in death cases than in those who survived in both groups. Mean blood glucose levels were higher in non- survivors when comparedto the survivors in both groups.
