Clinical Course of Chronic Pancreatitis in Elderly Patients.

Background: Several guidelines recommend the risk-adapted monitoring of patients with chronic pancreatitis (CP). However, dedicated risk stratification is widely missing in CP. Elderly-CP (disease onset with 60 or more years of age) may represent a subgroup of CP subjects with a distinct course of disease. Aims: We aimed to investigate the clinical presentation of elderly-CP, and if elderly-CP requires an adapted monitoring. Methods: Seven hundred forty one patients with CP were analyzed in a multicenter (Mannheim/Germany, n = 537; Gie ss en/Germany, n = 100; Donetsk/Ukraine, n = 104), cross-sectional, retrospective study and classified according to the M-ANNHEIM classification. Results: The frequency of elderly-CP was 20% (148/741). In comparison with non-elderly-CP, elderly-CP was less frequently caused by alcohol and nicotine dependency or genetic mutations. In contrast, the frequency of efferent duct abnormalities (p = 0.009, chi-square test) and idiopathic CP (p < 0.0001, chi-square test) increased significantly. The presence of multiple risk factors was found less frequently in elderly-CP than in non-elderly patients (p < 0.0001; chi-square test). Furthermore, elderly-CP was associated with increased rates of pseudocysts (p = 0.0002; chi-square test), endocrine insufficiency (p = 0.001; chi-square test), and the absence of pain (p = 0.04; chi-square test) in the first year of the disease. Conclusion: In elderly-CP, the course of disease significantly differs from non-elderly-CP. Therefore, individualized monitoring strategies for elderly-CP might be necessary.
