目的 探讨高脂血症性胰腺炎(HL-AP)病情严重程度的评估方法,寻找简便实用的检测指标.方法 选取2007年1月至2011年7月期间浙江省人民医院收治的62例HL-AP患者,分为轻症急性胰腺炎组(MAP)32例与重症急性胰腺炎组(SAP)30例两组,所有病例纳入及分组标准均参照《中国急性胰腺炎诊治指南》,分组后方差齐性检验两组具可比性.所有病例于入院后即刻抽动脉血检测血气分析,入院后次日晨6点抽肘静脉血检测肾功能、凝血功能等,提取碱剩余(base excess,BE)、肌酐(creatinine,CR)、C-反应蛋白(CRP)、纤维蛋白原(fibrin,FIB)和D-二聚体(D-dimmer,D-D)等值,入院48 h内均行胰腺增强CT检查,并予APACHEⅡ评分及BathazarCT严重指数(CTSI)评分.使用SPSS 18.0统计软件行t检验法分析两组间BE、CR、CRP、FIB、D-D的差异性,Spearman法分析各项指标与APACHEⅡ评分及CTSI的相关性,同时设定BE＜-4.5 mmol/L,CR＞ 120 μmol/L,CRP＞ 100 mg/L,FIB＞ 5.5 g/L,D-D＞ 800 ng/ml为各阳性筛选标准,分析其单独和联合作为SAP诊断标准时的阳性预测值(PPV)、阴性预测值(NPV)、灵敏度与特异度.结果 SAP组的BE、CR、CRP、FIB、D-D值均较MAP组明显升高(BE绝对值升高),P＜0.01.所有指标与APACHEⅡ评分及CTSI有良好的相关性,P＜0.01,以BE与D-D为明显.各指标单独诊断SAP均具有较高的PPV与NPV,且特异度高,但灵敏度不高,联合检测BE、CR和CRP与联合检测FIB和D-D能提高PPV与特异度,但灵敏度下降.结论 BE、CR、CRP、FIB、D-D等指标能直观快捷地反映高脂血症性胰腺炎的病情严重程度,为评估与预测病情严重程度的良好指标.“,”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.
