BACKGROUND AND AIMS: To evaluate impact of ambulatory triglyceride levels on risk of recurrent pancreatitis in patients with hypertriglyceridemic pancreatitis.

METHODS: We conducted a longitudinal retrospective cohort study of patients with serum triglyceride level ≥ 500 mg/dL during index hospitalization for acute pancreatitis within a regional integrated healthcare system between 2006 and 2013 (follow-up through 2015). Cases were identified based on combination of diagnosis codes and serum amylase/lipase. We used multivariable robust Poisson regression to determine independent effect of baseline (first outpatient) triglyceride measurement on risk of recurrent pancreatitis. Ambulatory triglyceride levels were categorized as normal (0-200 mg/dL), moderately elevated (201-500 mg/dL), and highly elevated (> 500 mg/dL). We further assessed factors related to likelihood of normalization of serum triglycerides (< 200 mg/dL) in the outpatient setting.RESULTS: One hundred and fifty-one patients met study inclusion criteria with median follow-up of 3 years. Overall, 45 (29.8%) patients experienced at least 1 recurrent attack with 25 (16.6%) experiencing multiple episodes. In multivariable analysis, patients that continued to have moderately elevated ((adjusted rate ratio RR 5.47 (95% CL 1.80, 16.65)) as well as highly elevated (RR 8.45 (2.55, 27.96)) triglycerides were at increased risk of disease recurrence compared to patients that achieved normalization. Patients with triglyceride measurement performed within 30 days from discharge were more likely to achieve normalization, 40 versus 26%, p = 0.03.CONCLUSIONS: For patients with hypertriglyceridemic pancreatitis, even modest elevation in subsequent triglyceride levels was associated with increased risk of recurrence. Future efforts should focus on ensuring timely care in the outpatient setting with a goal of normalizing triglycerides. Leggi l'articolo
