Background:
The ability to predict the severity of disease is important to reduce morbidity and mortality in patients with acute pancreatitis (AP). Vitamin D deficiency has been associated with severity in various diseases.
Objective:
This study was conducted to assess vitamin D as a predictor of disease severity in patients with AP.
Methods:
Patients with AP were prospectively enrolled at Yonsei University Wonju College of Medicine from March 2015 to September 2017. Serum vitamin D was analyzed as soon as AP was diagnosed. The level of vitamin D was classified as normal (>20 ng/ml), insufficient (>10 and ≤20 ng/ml) or deficient (≤10 ng/ml).
Results:
Among 242 patients with AP, the prevalence of vitamin D deficiency was 56.2%, and 28.5% of patients had vitamin D insufficiency. Serum vitamin D level was negatively correlated with severity indexes, such as the Atlanta classification, Computed Tomography Severity Index, Bedside Index for Severity of Acute Pancreatitis, and Ranson score. The prevalence of vitamin D deficiency increased with severity of AP according to the Atlanta classification. Vitamin D deficiency was the independent factor for predicting severe AP (OR 5.37, 95% CI 1.13-25.57, p = 0.015) and intensive care unit admission (OR 3.09, 95% CI 1.24-7.69, p = 0.035).
Conclusion:
Vitamin D deficiency is associated with increased severity of AP and is a predictor for intensive care unit admission.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:03Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
01:23Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
