The association between hypovitaminosis D and acute pancreatitis has not been studied. Aim: To study the incidence of vitamin D deficiency in patients with acute pancreatitis and assess the correlation,

if any, between hypovitaminosis D and severity, complications and outcome of acute pancreatitis. Methods: The records of 94 patients Y 27632 (56M; age 38 ± 13.34 years) with acute pancreatitis who were admitted in a tertiary care teaching hospital between January 2011 and October 2012 were retrospectively analyzed. The clinical, laboratory, radiological parameters, need for intervention and final outcome were retrieved. Vitamin D levels were estimated within 48 hrs of admission into hospital. Results: The most common etiology of AP was alcohol intake (n = 39; 41.4%) followed by gallstone disease (n = 32; 34%). Eighty (86.2%) patients had severe disease (Atlanta criteria) and 76 (80.9%) patients had necrotizing pancreatitis. Persistent organ failure

was noted in 48 (51%) patients of which respiratory failure was the most common (n = 39; 41.5%). The mean CTSI was 6.65 ± 2.70 and 7 (7.4%) patients buy Talazoparib succumbed to their illness. The mean vitamin D levels in the patients studied were 21.4 ± 23.7 ng/mL. The mean corrected calcium and phosphate levels were 7.7 ± 72 mg/dL and 3.0 ± 1.49 mg/dL. Seventy three (77.7%) patients

were found to be vitamin D deficient (Vit D levels <30 ng/ml). Persistent organ failure was seen more commonly in patients with vitamin D deficiency compared to patients with normal vitamin D levels (56.2% vs. 33.3%; p = 0.04. However, compared to the vitamin D deficient group, those with normal vitamin D levels had similar incidence of pancreatic necrosis (p = 0.52), acute fluid collections (p = 0.38), severity as assessed by ever Atlanta criteria (p = 0.94), sepsis (p = 0.17), need for intervention percutaneous catheter drainage (p = 0.42)/surgery (p = 0.80) and mortality (p = 0.68). Conclusion: Patients of acute pancreatitis with Vitamin D deficiency have increased incidence of persistent organ failure and the effects of Vitamin D supplementation in the outcome of acute pancreatitis needs to be further studied.
