ABSTRACT
OBJECTIVE:To investigate the effects of plasma exchange (PE) combined with intensive insulin glycemic control on related indexes of patients with HLP.METHODS:A total of 120 HLP patients were randomly divided into control group (60 cases) and observation group (60 cases).Based on routine treatment,2 groups were given PE treatment for 3 times+Low molecular weight heparin calcium for injection 5 000 U subcutaneously+Methylprednisolone sodium succinate for injection 40 mg intravenously+Calcium gluconate injection 2 g intravenously.Based on it,Insulin injection was pumped to random blood glucose ＜12 mmol/L with a micro-infusion pump in control group when random blood glucose concentration was equal to or more than 12 mmol/ L.When random blood glucose of patients in observation group were higher than 8.3 mmol/L,Insulin injection was pumped with a micro-infusion pump for a week and random blood glucose concentration was maintained at 6.1-8.3 mmol/L.Plasma levels of triglyceride,PCT,WBC count,APACHE Ⅱ score,Balthazar CT score,length of hospitalization stay in ICU and the occurrence of ADR were observed in 2 groups before and after treatment.RESULTS:After treatment,plasma levels of triglyceride,amylase and PCT,WBC count,APACHE Ⅱ score and Balthazar CT score in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statistical significance(P＜0.05).Length of hospitalization stay in ICU observation group was significantly shorter than control group,with statistical significance(P＜0.05).There was no statistical significance in the incidence of ADR between 2 groups(P＞0.05).CONCLUSIONS:PE combined with intensive insulin glycemic control can effectively reduce the level of plasma triglyceride,relieve inflammatory reaction and improve prognosis without increasing the occurrence of ADR.
ABSTRACT
Objective To investigate the methods used for evaluating the severity of the patients with acute pancreatitis induced by hyperlipidemia in order to find out some simple and practical biomarkers for predicting the severity of the illness.Methods Sixty-two patients with acute pancreatitis resulted from hyperlipidemia were selected from the in-patients of our hospital from January 2007 to July 2011 and were divided into two groups,namely the mild acute pancreatitis group(MAP,n =32)and the severe acute pancreatitis group(SAP,n =30)as per the Chinese Acute Pancreatitis Guideline.Two groups were comparable verified by the test of homogeneity of variance after grouping.Arterial blood gas analyses were done immediately after admission:Venous blood was taken from forearm for determining renal function and blood coagulation at 6 o＇lock of next day after admission.The data of base excess(BE),creatinine(CR),C-reactive protein(CRP),fibrin(FIB)and D-Dmmer(D-D)were documented.The contrast CT imaging of pancreas was done within 48 hours after admission in all patients.APACHE Ⅱ scores and computed tomography severity index(CTSI)were calculated.The differences in BE,CR,CRP,FIB and D-D between 2 groups were analyzed by using t-test,and the correlation among them and APACHE Ⅱ score and CTSI were analyzed by Spearman test done with SPSS 18.0 software.As BE ＜-4.5 mnol/L,CR ＞ 120μmol/L,CRP ＞ 100 mg/L,FIB ＞5.5 g/L and D-D 800 ng/L were set respectively as a positive screening criterion,positive prediction value(PPV),negative prediction value(NPV),sensitivity and specificity of each marker and combined markers were calculated after they were set at different positive scales in order to get the optimal predictors for evaluating the severity of acute pancreatitis induced by hyperlipidemia.Results The absolute values of BE,CR,CRP,FIB and D-D in group SAP were much higher than those in group MAP(P ＜ 0.01).Each of them had good correlation with APACHE Ⅱ score and CTSI,especially BE and D-D more significant.Each of them used separately for predicting the severity of acute pancreatitis showed PPV and NPV with high specificity but the sensitivity was hot high.The joint use of BE,CR and CRP,and joint use of FIB and D-D could be more valid as PPV and NPV with high specificity for predicting the severity of acute pancreatitis,but the sensitivity decreased.Conclusions BE,CR,CRP,FIB and D-D were good biomarkers for quickly and accurately evaluating and predicting the severity of the acute pancreatitis caused by hyperlipidemia.
ABSTRACT
Recently,there is a gradual increase in the incidence of hyperlipidemic pancreatitis with high serum triglyceride (TG) levels.The treatments include general measures,lipid-lowering drugs,blood purification,low molecular weight heparin and insulin,traditional medicine,improving microcirculation,surgical therapy and gene therapy.The prevention of recurrence of hyperlipidemic pancreatitis is different from other types of pancreatitis.
ABSTRACT
Objective Metabonomics method based gas chromatography-mass spectrometry (GC/MS)were used to analyze the urine samples of patients with hyperlipidemic pancreatitis (HLP) to describe the characteristics of metabolism changes of HLP,identify potential biomarkers,and investigate the role of metabonomics study in the management of AP.Methods 24 patients of HLP and 40 age,sex matched volunteers were enrolled and their urine samples were collected.The urine samples underwent preparation,derivation and GC/MS analysis,Orthogonal-Projection to Latent Structures-Discriminant Analysis (OPLS-DA)were performed to detect the metabolic profile difference between the HLP and control group.Results HLP patients can be precisely distinguished from healthy controls.21 metabolites (credibility ＞ 700 ) were identified using the reference compounds available in the libraries of NIST and Wiley.It was identified that levels of nicotinic acid,aconitie acid,citric acid,hippurie acid,hydroxyphenylacetic acid,hydroxyphenylpropionicacid were decreased,while the levels of tryptophan,tyrosine,tyramine,16-hexadecanoic acid,18octadecanoie acid were increased.It was also suggested that there was change in tricarboxylic acid cycle and gut bacterial flora,as well as fat metabolism and metabolism of amino acid.Conclusions There are differences between healthy controls and HLP patients in the term of GC/MS metabolic profiling,and the biomarkers in the metabolites could be found through metabonomics analysis,and the mechanisms of the metabolic changes could be explored.It was noted that the research of metabolites in the urine samples may be a useful tool to help diagnose and understand the pathogenesis of HLP.Metabonomics analysis is a promising research method.
ABSTRACT
It is well recognized that there is an association between hyperlipidemia and pancreatitis. However, it is not so easy to define clearly whether lipid abnormalities are the cause or the result of pancreatitis. Generally, a serum level of more than 1,000 mg/dL of triglyceride is an identifiable risk factor of hyperlipidemic pancreatitis in patients with type I, IV, or V hyperlipidemia classified by Fredrick's criteria. The clinical course as well as the management of hyperlipidemic pancreatitis is not different from that of pancreatitis of other causes. A thorough family history of lipid abnormalities should be obtained and an attempt to identify secondary causes should be made. The mainstay of treatment includes dietary restriction of fat and lipid-lowering medications. In Korea, there have been reported several cases of hyperlipidemic pancreatitis but familial history of hyperlipidemia has never been identified. We experienced a case of acute type IV hyperlipidemic pancreatitis in a patient suspected of familial combined hyperlipidemia. So, we report this case with the review of related literature.
