BackgroundHypertriglyceridemia-induced acute pancreatitis (HTG-AP) is an increasingly recognized and potentially severe form of acute pancreatitis. The effective management of HTG-AP is critical due to its association with significant morbidity and mortality. HTG-AP poses a considerable burden on affected individuals and healthcare systems. It can result in persistent upper abdominal pain, nausea, vomiting, abdominal distension, fever, and in severe cases, hypotension or shock and multiple organ dysfunction. Standard treatment strategies often involve lipid-lowering agents, but the optimal therapeutic approach remains a subject of ongoing research. This study aims to evaluate the efficacy of atorvastatin calcium, fenofibrate, and acipimox, either individually or in combination, in the treatment of HTG-AP, providing insights into more effective management strategies.Methods150 HTG-AP patients admitted to the first hospital of Putian from June 2020 to December 2022 were selected. The age range of the patients included in the study was between 30 and 70 years, with an average age of approximately 48 years. The cohort consisted of 90 males and 60 females, resulting in a male-to-female ratio of 3:2. The patients were grouped: atorvastatin calcium, acipimox, fenofibrate, fenofibrate + Atorvastatin calcium, fenofibrate + acipimox, and no drug. The therapeutic effects and clinical indicators of the six groups were compared.ResultsPatients in the fenofibrate + acipimox and fenofibrate groups experienced significantly reduced hospitalization duration compared to the other groups. They also had shorter abdominal pain relief time and gastrointestinal function relief time. Additionally, these groups had lower peak levels of amylase (an enzyme) and cholesterol compared to the other groups. In terms of neutrophil (NEUT) increase, the fenofibrate + acipimox, atorvastatin calcium, and fenofibrate groups had significantly lower peak levels compared to the other groups, indicating a less pronounced increase in NEUT. Furthermore, the fenofibrate and acipimox groups exhibited significantly lower peak levels of C-reactive protein (CRP) compared to the other groups. CRP is an indicator of inflammation. On the other hand, the atorvastatin calcium group had higher levels of procalcitonin (a marker of infection) and a higher peak score on the acute physiology and chronic health evaluation II (APACHE II) scale, which assesses the severity of acute pancreatitis, compared to the other groups (all P < .05).ConclusionThe findings of this study highlight the effectiveness of combining fenofibrate and acipimox in the treatment of HTG-AP, leading to rapid disease recovery and significant improvement in clinical symptoms. These results have important implications for clinical practice, as the combination therapy can be widely adopted as an effective treatment strategy for HTG-AP patients. Moreover, this study provides valuable insights into the management of HTG-AP and suggests that lipid-lowering agents, such as atorvastatin calcium and fenofibrate, play a crucial role in the treatment of this condition. However, further research is needed to explore the optimal dosages, treatment durations, and potential side effects of these medications in HTG-AP patients.
