Analysis of the clinical profile and treatment efficiency of hyperlipidemic acute pancreatitis

BackgroundThe incidence of hyperlipidemic acute pancreatitis (HLAP) has been increasing annually. However, population-based morbidity assessments need to be updated. Early, rapid, and effective lipid-lowering may minimize pancreatic injury and improve clinical prognosis. It is essential to choose the proper treatment. However, treatment options for HLAP are controversial, and there is no uniform treatment protocol.MethodsIn this retrospective study, 127 patients with hyperlipidemic severe acute pancreatitis (HL-SAP) were registered from January 2018 to December 2022 at the General Hospital of Ningxia Medical University. Medical and radiological records of hospitalized patients were collected to determine clinical features, severity, complications, mortality, recurrence rate, and treatment. Risk factors for HL-SAP were analyzed using multifactorial logistic regression. A propensity score matching method was used to compare the clinical outcomes of standard and plasma exchange therapies.ResultsIn this research, the prevalence of HLAP increased about 1.6 times, and the prevalence of HL-SAP was 50.60%. HL-SAP occurs most often in people between the ages of 30 and 39. Amylase exceeded 110 U/L in 84.3% of patients and 330 U/L in only 47.2%. 83.5% of HL-SAP patients had fatty livers and high body mass index (BMI). A total of 48.0% of patients experienced organ failure, ICU treatment (55.1%), recurrence (33.1%), and death (21.3%). Between the hyperlipidemic group and the biliary group in terms of age, gender, BMI, fatty liver, pleural effusion, abdominal constriction syndrome (ACS), multiple organ dysfunction syndrome (MODS), length of hospital, medical costs, morbidity and mortality, triglyceride, cholesterol, creatinine, blood glucose, D-dimer, amylase, albumin, lactate dehydrogenase, serum phosphorus, serum calcium, oxygenation index, and recurrence rate were statistically significant (P < 0.05). High BMI (P = 0.0038, odds ratio (OR) = 1.336, 95%CI: 0.99–1.804), high C-reactive protein (CRP) (P = 0.022, OR = 1.011, 95%CI: 1.003–1.019), low calcium (P = 0.003, OR = 0.016, 95%CI. 0.001–0.239), low albumin (P = 0.012, OR = 0.045, 95%CI: -0.062-0.192), and high D-dimer (P = 0.041, OR = 0.619, 95%CI: 0.053–2.510) were risk factors for HL-SAP, according to multifactorial logistic regression analysis. Adjusted for propensity score matching (PSM), Serum triglyceride (TG) was significantly lower in both the standard treatment (P < 0.001) and plasma exchange (P < 0.001) groups at 48 h compared with the initial test after the attack. Clearance (83.20% ± 0.0% vs. 84.4% ± 0.0%, P = 0.531), length of hospital stay (19.9 ± 4.9 vs. 19.8 ± 11.1, P = 0.092), and death (26.3% vs. 23.6%, P = 0.791) showed no difference between the two groups. However, the difference in medical costs(P = 0.039)between the two groups was statistically significant.ConclusionThe incidence of HLAP exhibited a significant increase, remarkable severity, recurrent trend, and mortality. High BMI, high CRP, low calcium, low albumin, and high D-dimer are risk factors for HL-SAP. Compared with standardized treatment, plasma exchange does not improve the prognosis of HL-SAP patients, and standardized treatment is equally effective, safe, and low-cost in early treatment.

Comparison of clinical characteristics of severe hyperlipidemic pancreatitis and severe acute gallstone pancreatitis

Objective To compare the clinical characteristics and the outcomes of severe hyperlipidemic pancreatitis (SHLP) and severe acute gallstone pancreatitis (SAGP). Methods The clinical data of 22 patients with SHLP and 91 patients with SAGP admitted from January 2009 to December 2015 were retrospectively reviewed. The clinical manifestations, laboratory tests, organ dysfunction, medical treatment, complications and outcomes in 30 d after admission were analyzed and compared between two groups of patients. Results There were 16 males and 6 females with a mean age of (60.5±9.1) years in SHLP group; while 32 males and 59 females with a mean age of (54.3±5.4) years in SAGP group. The blood and urine amylase levels in SHLP group were significantly lower than those in SAGP group [(715±99) U/L vs. (1 551±107) U/L, t=4.65, P=0.00; (382±56) U/L vs. (773±66) U/L, t=4.52, P=0.00, respectively]. The incidence of circulation insufficiency, respiratory insufficiency, renal dysfunction, and long-term pulmonary infection in SHAP patients was significantly higher than that in SAGP patients [36%(8/22) vs.14%(13/91), χ2=5.22, P=0.01; 41%(9/22) vs.7%(6/91), χ2=9.46, P=0.01; 23%(51/22) vs.5%(5/91), χ2=4.20, P=0.03; 55%(12/22) vs. 32% (29/91), χ2=7.02, P=0.01]. Two cases died in the SHLP group and 9 cases died in SAGP group due to critical infection, cardiac events and bleeding. Conclusion Compared to SAGP patients, the blood and urine amylase levels are usually not remarkably high in SHLP patients, and the prevention and management of multi-organ failure and lung infection are more important for SHLP patients.

Sequential blood purification therapy for critical patients with hyperlipidemic severe acute pancreatitis.

To evaluate the efficacy of sequential blood purification therapy in the treatment of critical patients with hyperlipidemic severe acute pancreatitis. Thirty-one intensive care unit (ICU) patients with hyperlipidemic severe acute pancreatitis treated at the Second Affiliated Hospital of Harbin Medical University were divided into either a study group (n = 15; July 1, 2012 to June 30, 2014) or a control group (n = 16; July 1, 2010 to June 30, 2012) based on the implementation of sequential blood purification therapy. The control group received continuous venous-venous hemofiltration (CVVH) on the basis of conventional treatments, and the therapeutic dose of CVVH was 30 mL/kg per hour. The study group received sequential plasma exchange and CVVH on the basis of conventional treatments. The anticoagulation regimen of CVVH is the regional citrate anticoagulation. Mortality rate on day 28, rates of systemic and local complications, duration of ICU, and time to target serum lipid level, as well as physiologic and laboratory indices were compared between the two groups. The mortality rate on day 28 was significantly lower in the study group than in the control group (13.33% vs 37.50%; P < 0.05). The duration of ICU stay was significantly shorter in the study group than in the control group (7.4 ± 1.35 d vs 9.19 ± 2.99 d, P < 0.05). The time to target serum lipid level was significantly shorter in the study group than in the control group (3.47 ± 0.52 d vs 7.90 ± 1.14 d, P < 0.01). There were no significant differences in the rates of systemic complications and local complications between the two groups (60% vs 50% and 80% vs 81%, respectively). In the comparisons of physiologic and laboratory indices, serum albumin and C-reactive protein were significantly better in the study group than in the control group after treatment (37.8 ± 4.6 g/L vs 38.9 ± 5.7 g/L, and 20.5 ± 6.4 mg/L vs 28.5 ± 7.1 mg/L, respectively, both P < 0.05). With the exception of plateletcrit, no other indices showed significant differences between the two groups. Sequential blood purification therapy is effective in the treatment of ICU patients with hyperlipidemic severe acute pancreatitis and can improve patient prognosis.

Rosiglitazone attenuates the severity of hyperlipidemic severe acute pancreatitis in rats

Peroxisome proliferator-activated receptor-γ (PPAR-γ) ligand regulates adipocyte differentiation and insulin sensitivity, and exerts antihyperlipidemic and anti-inflammatory effects. However, the mechanisms by which PPAR-γ ligands affect hyperlipidemia with severe acute pancreatitis (SAP) have not been fully elucidated. The present study investigated the effects of rosiglitazone, a PPAR-γ ligand, on hyperlipidemia with SAP in a rat model. The hyperlipidemia was induced with a high-fat diet and SAP was induced by the administration of sodium taurocholate (TCA). The hyperlipidemia was shown to aggravate the severity of the sodium taurocholate-induced SAP. However, rosiglitazone demonstrated significant antihyperlipidemic and anti-inflammatory effects in the rats with high-lipid diet-induced hyperlipidemia and SAP.

Study on combined therapy of hyperlipidemic severe acute pancreatitis

To investigate the principle and measures of combined treatment of the patients with hyperlipidemic severe acute pancreatitis (HL-SAP). The clinical data of 54 patients with HL-SAP including two phases from January 1996 to December 2000 and from January 2001 to August 2006 were analyzed retrospectively. In the first phase, 25 patients were performed by routine methods to decrease triglyceride, or additional operative treatments. In the second phase, 29 cases were treated by multiple ways of non-operative combined therapy, or additional operative treatments mainly by minimally invasive procedures. Among 54 cases with HL-SAP, 33 cases (61.1%) received non-operative therapy and 21 cases (38.9%) received surgical intervention. Overall mortality was 18.5% (10/54). In the first phase of 25 cases, the mortality in non-operative group and surgical intervention group was 21.4% (3/14) and 36.3% (4/11), respectively. In the second phase of 29 cases, the mortality in non-operative group and surgical intervention group was 10.5% (2/19) and 10.0% (1/10), respectively. The overall curative rate, morbidity, overall mortality, content of triglyceride at the fourth day after onset, APACHE II score at the fourth day after onset and average stay were obviously improved in the second phase compared with the first phase (P < 0.05). According to individualized therapy principles, treatment for HL-SAP should emphasis on multiple ways of non-operative combined therapy and appropriate choices of the timing, indication in surgical intervention. And the choice of operative procedure should follow the principle of minimally invasive surgery. Meanwhile, pay more attention to monitoring and controlling the level of triglyceride post-discharge for the patients with the history of HL-SAP.

Formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis

To investigate a formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis (HL-SAP). 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 hours 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. Serum triglyceride level (mmol/L), TNFalpha (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. The First surgical intervention time was 55.8+/-42.6 days in SAP group (5 patients) and 12.2+/-6.6 days 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. 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 days (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 days in SAP group. Penta-association therapy is an effective guideline in the treatment of hyperlipidemic severe acute pancreatitis at its early stage (within 72 hours).
