Background
No specific triglyceride-lowering therapy is recommended in patients with hypertriglyceridemia-associated acute pancreatitis (HTG-AP), primarily because of the lack of quality evidence. This study aimed to describe practice variations in triglyceride-lowering therapies for early HTG-AP patients and assess whether more rapid triglyceride decline is associated with improving organ failure.
Methods
This is a multicentre, prospective cohort study recruiting HTG-AP patients with elevated plasma triglyceride (> 11.3 mmol/L) admitted within 72 h from the onset of symptoms. Patients were dichotomised on study day 3 into either target reaching (plasma triglyceride ≤ 5.65 mmol/L) or not. The primary outcome was organ failure-free days (OFFD) to 14 days of enrolment. The association between target-reaching and OFFD was modelled. Additionally, the slope in plasma triglyceride over the first three days in response to treatment was calculated, and its association with OFFD was assessed as a sensitivity analysis.
Results
Among the 300 enrolled patients, 211 underwent exclusive medical treatment, and 89 underwent various blood purification therapies. Triglyceride levels were available in 230 patients on study day 3, among whom 122 (53.0%) had triglyceride levels of ≤ 5.65 mmol/l. The OFFD was not different between these patients and those in whom plasma triglyceride remained > 5.65 mmol/L [median (IQR): 13 (10–14) vs. 14 (10–14), p = 0.46], even after adjustment for potential confounders. For the decline slopes, there was no significant change in OFFD with a steeper decline slope [risk difference, − 0.088, 95% CI, − 0.334 to 0.158, p = 0.48].
Conclusions
Triglyceride-lowering therapies vary greatly across centres. More rapid triglyceride decline was not associated with improving incidence and duration of organ failure.
