Clinical characteristics of three distinct types of pancreatitis with overlapping etiologies: A ten-year retrospective cohort study

Hypertriglyceridemia (HTG) is frequently observed in non-HTG-induced acute pancreatitis (AP), such as in the early stage of acute biliary pancreatitis (ABP). There is overlap in the etiologies of ABP, HTG-AP, and biliary-hypertriglyceridemia acute pancreatitis (BHAP), which may be perplexing for clinicians.We retrospectively analyzed 394 AP patients. The patients were divided into three groups based on etiology. We analyzed the differences among the three groups of patients in terms of general information, laboratory parameters, and prognosis.The mean age of patients in the ABP group was significantly higher than that in the HTG-AP and BHAP groups (p < 0.001). Females made up a greater percentage of the ABP group, whereas males made up the majority in the HTG-AP and BHAP groups. The ABP group had the highest PCT, AMS, LPS, ALT, AST, GGT, TBIL, DBIL, APACHE II, and BISAP scores. TG and BMI were highest in the HTG-AP group. AST and GGT levels were substantially greater in BHAP patients than those in HTG-AP. The BHAP group had the greatest incidence of organ failure, systemic complications, and local complications.ABP usually develops in people aged 50-59 years. HTG-AP primarily affects people aged 30-39 years. However, the peak incidence age of BHAP falls between the two aforementioned age groups (40-49 years). We also found that patients with BHAP seem to be in an intermediate state in terms of some biochemical markers and demographic characteristics. Furthermore, BHAP may have the worst clinical outcomes compared with HTG-AP and ABP.
