Objective: Pancreatic calcifications is a common finding in patients with chronic pancreatitis (CP), but the underlying pathophysiology is incompletely understood. Past studies for risk factors of calcifications have generally been focused on single parameters or limited by small sample sizes. The aim of this study was to explore several patient and disease characteristics and their associations with pancreatic calcifications in a large cohort of CP patients with diverse etiological risk factors. Methods: This was a multicenter, cross-sectional study including 1509 patients with CP from the Scandinavian and Baltic countries. Patient and disease characteristics were compared for patients with calcifications (n=912) vs. without calcifications (n=597). Multivariable logistic regression was performed to assess the parameters independently associated with calcifications. Results: The mean age of patients was 53.9±14.5 years and 1006 (67%) were men. The prevalence of calcifications was 60.4% in the overall patient cohort, but highly variable between patients with different etiological risk factors (range: 2-69%). On multivariate analysis, alcoholic etiology (OR 1.76 [95% CI, 1.39-2.24]; p<0.001) and smoking (OR 1.77 [95% CI, 1.39-2.26], p<0.001) were positively associated with the presence of calcifications, while an autoimmune etiology was negatively associated with calcifications (OR 0.15 [95% CI, 0.08-0.27], p<0.001). Patients with pancreatic calcifications were more likely to have undergone pancreatic duct stenting (OR 1.59 [95%CI, 1.16-2.19], p=0.004). Conclusion: The presence of pancreatic calcifications is associated with etiological risk factors in patients with CP. This observation attest to the understanding of CP as a complex disease and may have implications for disease classification.
