AIM: To investigate a formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis (HL-SAP).
METHODS: Thirty-two consecutive patients with severe acute pancreatitis were included in the clinical trial. All of them met the following five criteria for admission to the study, namely the Atlanta classification and stratification system for the clinical diagnosis of SAP, APACHEII score more than 8, time interval for therapeutic intervention less than 72 h after onset of the disease, serum triglyceride (TG) level 6.8 mmol/L or over, and exclusion of other etiologies. They were divided into severe acute pancreatitis group (SAP, 22 patients) and fulminant severe acute pancreatitis group (FSAP, 10 patients). Besides the conventional therapeutic measures, Penta-association therapy was also applied in the two groups, which consisted of blood purification (adsorption of triglyceride and hemofiltration), antihyperlipidemic agents (fluvastatin or lipanthyl), low molecular weight heparin (fragmin), insulin, topical application of Pixiao (a traditional Chinese medicine) over the whole abdomen. Serum triglyceride, pro-inflammatory cytokines and anti-inflammatory cytokines were determined before blood purification (PF), at the end of blood purification (AFE) and on the 7th day after onset of the disease (AF7) respectively. Simultaneously, severity of the diseases was assessed by the APACHE II system. Prognosis was evaluated by non-operation cure rate, absorption rate of pseudocyst, time interval pseudocyst absorption, hospital stay and survival rate.
RESULTS: Serum triglyceride level (mmol/L), TNFα (U/mL) concentration and APACHE II score were significantly decreased (P < 0.05) at AFE and AF7, as compared with PF. However, serum IL-10 concentration (pg/mL) was increased significantly (P < 0.001) at AFE, and decreased significantly (P < 0.05) at AF7 when compared with PF. Operations: The First surgical intervention time was 55.8 ± 42.6 d in SAP group (5 patients) and 12.2 ± 6.6 d in FSAP group (7 patients), there was a significant difference between the two groups (P = 0.02). The number of operations in the two groups was 1.33 ± 0.5 vs 3.5 ± 1.2 (P = 0.0037), respectively. Prognosis: Non-operation cure rate, absorption rate of pseudocyst, hospital stay and survival rate in SAP group and FSAP group were 100% (22/22) vs 11.1% (1/9), 77.3% (17/22) vs 11.1% (1/9), 54.2 ± 35.9 vs 99.1 ± 49.5 d (P = 0.008) and 100% (22/22) vs 66.7% (6/9) (P = 0.0044). The time for absorption of pseudocyst was 135.1 ± 137.5 d in SAP group.
CONCLUSION: Penta-association therapy is an effective guideline in the treatment of hyperlipidemic severe acute pancreatitis at its early stage (within 72 h).
