Abstract

Objectives: Drug-associated acute pancreatitis (DAP) studies typically focus on single acute pancreatitis (AP) cases. We aimed to analyze the (1) characteristics, (2) co-risk factors, and (3) reliability of the Naranjo scoring system for DAP using INSPPIRE-2 (the INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2) cohort study of acute recurrent (ARP) and chronic pancreatitis (CP) in children. Methods: Data were obtained from ARP group with ≥1 episode of DAP and CP group with medication exposure +/- DAP. Physicians could report multiple risk factors. Pancreatitis associated with Medication (Med) (ARP+CP) was compared to Non-Medication cases, and ARP-Med vs CP-Med groups. Naranjo score was calculated for each DAP episode. Results: Of 726 children, 392 had ARP, 334 CP. 51 children (39 ARP and 12 CP) had ≥ 1 AP associated with a medication. 61% had ≥ 1 AP without concurrent medication exposure. The Med group had other risk factors present (where tested): 10/35 (28.6%) genetic, 1/48 (2.1%) autoimmune pancreatitis, 13/51 (25.5%) immune-mediated conditions, 11/50 (22.0%) obstructive/ anatomic, 28/51 (54.9%) systemic risk factors. In Med group, 24/ 51 (47%) had involvement of >1 medication, simultaneously or over different AP episodes. There were 20 ARP and 4 CP cases in “probable” category and 19 ARP and 7 CP in “possible” category by Naranjo scores. Conclusions: Medications were involved in 51/ 726 (7%) of ARP or CP patients in INSPPIRE-2 cohort; other pancreatitis risk factors were present in most, suggesting a potential additive role of different risks. The Naranjo scoring system failed to identify any cases as “definitive”, raising questions about its reliability for DAP.
