Celiac disease is associated with increased risk of deep vein thrombosis and hypotensive shock in patients admitted with acute pancreatitis.

Background and Aim: Celiac disease (CD) was shown to be associated with increased risk of developing acute pancreatitis (AP). There is a paucity of literature critically analyzing the association of CD with AP outcomes. We aimed to evaluate the impact of CD on outcomes and complications of AP in recent years. Methods: A population-based analysis was performed using the National Inpatient Sample (NIS) between 2016 and 2019. Multivariable logistic regression was conducted to identify the independent impact of CD on AP outcomes while controlling for demographics and comorbidities and all patients refined diagnosis-related groups (APR-DRG) risk of severity subclass. Results: From 2016 to 2019, a total of 2 253 730 inpatients with AP were identified, of which 4640 (0.2%) had CD. On multivariable analysis, while controlling for demographics, comorbidities, and severity of illness, CD patients had significantly decreased odds for mortality (OR = 0.387), pseudocyst formation (OR = 0.786), sepsis (OR = 0.707), respiratory failure (OR = 0.806), acute kidney injury (AKI) (OR = 0.804), and myocardial infarction (OR = 0.217), ( Conclusions: Our nationwide study evaluating AP outcomes in patients with CD suggests that patients with CD admitted for AP tend to have better mortality and several other outcomes compared to non-CD patients. We also show that CD patients admitted for AP have a greater risk for DVT and hypotensive shock. Future studies are warranted to validate the revealed findings in CD patients admitted for AP.
