Hypertriglyceridemia-induced pancreatitis treated with continuous insulin infusion-Case series

Comparative efficacy of therapeutic plasma exchange and insulin in hypertriglyceridemia-induced acute pancreatitis

INTRODUCTION

Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) presents a therapeutic challenge with no currently definitive treatment, including therapeutic plasma exchange (TPE) and insulin. TPE aims to quickly reduce serum triglyceride (TG); however, its efficacy lacks convincing evidence. Intravenous insulin is a promising and convenient alternative, while comparative data is limited.

METHODS

This retrospective, single-center study compared TPE and insulin treatment in HTG-AP patients. The primary outcome measured was the percentage of TG reduction within 48 hours of admission.

RESULTS

The study included 33 TPE-treated and 56 insulin-treated patients. The TPE groups were more severe than those with medical therapy at baseline characteristics. A trend towards higher TG reduction within 24 hours was observed in the TPE group (62.5% [IQR 51.7-83.3] vs. 55.7% [IQR 34.2-74.7], p = 0.038). However, no significant difference in TG reduction at 48 hours was found between insulin and TPE groups (83.6% and 81.9%, respectively, p = 0.715). The TPE group exhibited extended hospital stays (10.0 [IQR 7.0-13.5] days vs. 6.0 [4.0-8.7] days, p = 0.001) without any difference in in-hospital mortality or time needed to lower TG below < 11.3 mmol/L.

CONCLUSION

In patients with HTG-AP, TPE decreased plasma triglyceride levels faster in the first 24 hours than insulin therapy. However, there was no significant advantage after 48 hours. Therefore, insulin may be a promising alternative and convenient treatment in carefully selected patients with HTG-AP.

The effect of serum triglyceride levels and different lipid-lowering methods on the prognosis of hypertriglyceridemic acute pancreatitis: a single-center 12-year retrospective study by propensity score matching

AIM

To investigate the impact of triglyceride on hypertriglyceridemic acute pancreatitis (HTG-AP) and different lipid-lowering methods on triglyceride-lowering efficiency and HTG-AP.

METHODS

The patients with HTG-AP from January 2012 to December 2023 in Civil Aviation General Hospital were analyzed, retrospectively. Patients were divided and compared according to whether their triglycerides were below 5.56 mmol/L at 48 and 72 h of admission. The patients were divided into control group, insulin group, and low molecular weight heparin (LMWH)+bezafibrate group based on the different methods of lipid-lowering. Propensity score matching (PSM) was employed to balance the baseline characteristics.

RESULTS

There was no correlation between the severity of HTG-AP and the triglyceride at admission. The incidence of severity, local complications, and persistent organ failure (POF) were significantly decreased in patients with 48-h and 72-h triglyceride attainment. Following PSM, the incidence of infectious pancreatic necrosis (IPN) (3.3% vs. 13.3%) was significantly reduced in insulin group compared with control group (p < .05). Compared with control group, LMWH + bezafibrate group had higher lipid reduction efficiency, and the incidence of IPN (0.9% vs. 10.1%) and POF (8.3% vs. 19.3%) was significantly decreased (p < .05). There was no significant difference in the efficiency of lipid-lowering, complications, and POF between LMWH + bezafibrate group and insulin group (p > .05).

CONCLUSION

The severity of HTG-AP is not associated with the triglyceride levels at admission. However, rapid reduction of triglyceride levels can lower the incidence of local complications and respiratory failure. Compared with conservative treatment, insulin and LMWH + bezafibrate can both reduce the incidence of IPN in patients with HTG-AP.

Observed consensus on research priorities for the hypertriglyceridemia patient registry

BACKGROUND

Priority setting in health research has been described as essential due to disparities within and between countries and populations. Commercial benefits to the pharmaceutical industry may increase the generation and use of regulatory Real-World Evidence which has recently been reported in the literature. Research must be steered by valuable priorities. This study's objective is to identify key gaps in the knowledge of triglyceride-induced acute pancreatitis by generating a list of potential research priorities for a Hypertriglyceridemia Patient Registry.

METHOD

The Jandhyala Method was used to observe the consensus of expert opinion from ten specialist clinicians in the treatment of triglyceride-induced acute pancreatitis across the US and EU.

RESULTS

Ten participants completed the consensus round of the Jandhyala method and generated 38 unique items which they all agreed with. The items were included in the generation of research priorities for a hypertriglyceridemia patient registry and presented a novel application of the Jandhyala method for the development of research questions, in aid of the validation of a core dataset.

CONCLUSION

The TG-IAP core dataset and research priorities combined can develop a globally harmonized framework where TG-IAP patients can be observed simultaneously using the same set of indicators. This will increase knowledge of the disease and facilitate higher-quality research by addressing issues related to incomplete data sets in observational studies. Furthermore, validation of new tools will be enabled, and diagnosis and monitoring will be improved as well as the detection of changes in disease severity and subsequent disease progression, improving the management of patients with TG-IAP overall. This will inform personalized patient management plans and improve patient outcomes along with their quality of life.

Incidence and clinical treatment of hypertriglyceridemic acute pancreatitis: A few issues

Hypertriglyceridemia is a well-recognized etiology of acute pancreatitis, and the incidence of hypertriglyceridemic acute pancreatitis (HTG-AP) has increased in frequency worldwide in response to lifestyle changes. It is crucial to identify hypertriglyceridemia as the cause of pancreatitis and initiate appropriate treatment. Insulin treatment produces effective lowering of triglycerides, but in our opinion, non-diabetic patients with HTG-AP require separate consideration to avoid hypoglycemia.

Value of BISAP score for predicting severity of hyperlipidemic acute pancreatitis: A meta-analysis

BACKGROUND

Early identification of hyperlipidemic acute pancreatitis (HLAP) patients at risk of developing potentially lethal complications is of great clinical significance. Studies have suggested that the bedside index for in acute pancreatitis (BISAP) score is associated with adverse outcomes.

AIM

To assess the accuracy of BISAP score as a prognostic marker for severity of HLAP.

METHODS

A systematic search of main computerized databases was performed to identify eligible cohort studies on the predictive value of BISAP score for severity of HLAP. The STATA software and Meta-disc software were applied to carry out the meta-analysis.

RESULTS

Ten studies (n = 1591) were included. The overall sensitivity and specificity of BISAP score ≥ 3 for predicting mortality in HLAP were 0.85 (95% confidence interval [CI]: 0.65-0.96) and 0.86 (95%CI: 0.82-0.88), respectively; the area under the curve (AUC) was 0.937, and the diagnostic odds ratio (DOR) was 42.00 (95%CI: 12.86-139.12). Regarding the increase of BISAP score for prediction of severe acute pancreatitis (SAP), the pooled sensitivity was 0.69 (95%CI: 0.61-0.76), and the specificity was 0.82 (95%CI: 0.78-0.85), with AUC and DOR being 0.900 and 18.47 (95%CI: 6.82-42.03), respectively. The pooled sensitivity, specificity, and DOR for prediction of moderately severe acute pancreatitis (MASP) + SAP were 0.54 (95%CI: 0.50-0.63), 0.91 (95%CI: 0.89-0.93), and 15.55 (95%CI: 6.91-34.99), respectively; the AUC was 0.724. BISAP score was superior to APACH Ⅱ and Ranson score in predicting the severity of HLAP.

CONCLUSION

BISAP score is a reliable tool to identify the severity of HLAP, but it has a suboptimal sensitivity for predicting SAP and SAP + MSAP.

Safety and Efficacy of Various Intravenous Insulin Infusion Rates in Patients With and Without Diabetes Presenting With Hypertriglyceridemia

Background

The use of IV insulin infusions in the acute management of hypertriglyceridemia has only been evaluated in small observational studies and case reports.

Objective

To evaluate the safety and efficacy of IV insulin infusions in the acute management of hypertriglyceridemia.

Methods

This was a retrospective chart review of adult patients who received an IV insulin infusion for the acute management of hypertriglyceridemia. The primary efficacy and safety outcomes were the number of patients who achieved a triglyceride level <500 mg/dL and experienced hypoglycemia (<70 mg/dL), respectively. A subgroup analysis was performed to compare outcomes between patients with and without diabetes, in addition to the IV insulin infusion rate received.

Results

In the total population (n = 51), there were no statistically significant differences between the insulin intensity groups in the number of patients who achieved TG levels <500 mg/dL. Compared to patients with a past medical history of diabetes, more patients without a past medical history of diabetes achieved triglyceride levels <500 mg/dL (14% vs 53%, respectively, P < 0.001). The number of hypoglycemic events observed in patients with and without a past medical history of diabetes were 5 (14%) and 4 (27%), respectively ( P = 0.023).

Conclusion and Relevance

Our findings suggest that patients who present with lower initial TG levels are more likely to achieve TG levels <500 mg/dL. To minimize the risk of hypoglycemia providers should consider prescribing a concomitant dextrose infusion and limiting IV insulin infusion rates ≤ 0.075 units/kg/h.
