Prevalence of Chronic Metabolic Comorbidities in Acute Pancreatitis and Its Impact on Early Gastrointestinal Symptoms during Hospitalization: A Prospective Cohort Study.

Abstract

Background: The prevalence of chronic comorbidities is increasing worldwide, and this has been paralleled by a growing interest in how these comorbidities affect patients with acute pancreatitis. The aim was to investigate the associations between pre-existing diabetes mellitus, obesity, metabolic syndrome, and gastrointestinal symptoms during the early course of acute pancreatitis.

Methods: This was a prospective cohort study of patients with a primary diagnosis of acute pancreatitis. Study groups were formed based on the presence of metabolic comorbidities (pre-existing diabetes mellitus, obesity, and metabolic syndrome). Patient-reported outcomes (nausea, bloating, and abdominal pain) were collected prospectively every 24 h (including weekends and public holidays) over the first 72 h of hospitalization.

Results: A total of 183 consecutive patients were enrolled. Of them, 111 (61%) had at least one major metabolic comorbidity. Patients with pre-existing diabetes mellitus and those with metabolic syndrome had worse nausea at 49-72 h of hospitalization (p = 0.017 and p = 0.012, respectively), but not at other time points. Bloating and abdominal pain did not differ between the study groupings throughout the study period. The studied patient-reported outcomes did not differ significantly between acute pancreatitis patients with and without obesity at any point in time.

Conclusion: More than 3 out of 5 patients hospitalized for acute pancreatitis have at least one major chronic metabolic comorbidity. The presence of metabolic comorbidities does not considerably and consistently affect early gastrointestinal symptoms in patients with acute pancreatitis.
