Abstract
Background
This study was conducted to evaluate the risk of developing acute pancreatitis (AP) and the fatality from AP in hemodialysis (HD) and peritoneal dialysis (PD) patients, using the claims data of Taiwan National Health Insurance.
Methods
From patients with newly diagnosed end-stage renal disease (ESRD) in 2000–2010, we identified a PD cohort (N = 9,766), a HD cohort (N = 18,841), and a control cohort (N = 114,386) matched by sex, age, and the diagnosis year of the PD cohort. We also established another 2 cohorts with 9,744 PD patients and 9,744 propensity score-matched HD patients. The incident AP and fatality from AP were evaluated for all cohorts by the end of 2011.
Results
The adjusted hazard ratios (HRs) of acute pancreatitis were 5.68 (95% confidence interval [CI] = 5.05 – 6.39), 4.91 (95% CI = 4.32 – 5.59), and 7.47 (95% CI = 6.48 – 8.62) in the all dialysis, HD, and PD patients, compared with the controls, respectively. Peritoneal dialysis patients had an adjusted HR of 1.41 (95% CI = 1.21 – 1.65) for AP, compared with propensity score-matched HD patients. Peritoneal dialysis patients under icodextrin treatment had a lower incidence of AP than those without the treatment, with an adjusted HR of 0.59 (95% CI = 0.47 – 0.73). There was no significant difference in the 30-day mortality from AP between HD and PD patients.
Conclusions
Peritoneal dialysis patients were at a higher risk of developing AP than HD patients. Icodextrin solution could reduce the risk of developing AP in PD patients.
