熊去氧胆酸及其联合激素和免疫抑制剂治疗原发性胆汁性肝硬化的临床观察 总被引:1,自引:1,他引:0
目的 观察熊去氧胆酸(UDCA)、UDCA联合泼尼松龙、UDCA联合硫唑嘌呤3种方案治疗对原发性胆汁性肝硬化(PBC)的疗效,并评价影响疗效的危险因素.方法 82例初诊PBC患者随机分为单用UDCA(U组,28例)、UDCA联合泼尼松龙(UP组,27例)、UDCA联合硫唑嘌呤(UA组,27例)3个治疗组,在治疗第0、3、6、12个月采集临床、实验室资料及药物不良反应.主要采用重复测量的方差分析和COX回归进行统计学处理.结果 UP组患者较U组及UA组在乏力和瘙痒程度上有明显改善(P=0.015和P=0.037),U组、UA组无改善.3组患者治疗后丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、碱性磷酸酶(ALP)、谷氨酰转肽酶(GGT)、总胆红素、直接胆红素(DBIL)和IgM均下降,组内比较差异有统计学意义(P<0.05),3组间比较差异无统计学意义(P>0.05).发生疾病进展的患者Mayo危险性评分高(P=0.018)、凝血酶原时间(PT)延长(P=0.042).UP组血糖升高2例、满月脸5例、多毛1例;UA组白细胞下降2例,胆绞痛1例,U组未出现药物不良反应.ALP、GGT、总胆固醇基线水平高是生化缓解的危险因素(P=0.015).总胆红素、DBIL、总胆汁酸增高、PT延长不利于肝生化缓解(P=0.075).结论 3种方案对PBC患者肝脏生化指标、IgM的改善作用相近,UDCA联合泼尼松龙方案可减轻乏力、瘙痒症状,单用UDCA方案不良反应发生率最低.Mayo危险性评分高、PT延长的患者疾病易进展;高水平的ALP、GGT、总胆固醇是生化缓解的危险因素;高水平的总胆红素、DBIL、总胆汁酸、PT不利于生化缓解.Abstract: Objective The aims of this study were to compare the clinical and laboratory responses to ursodeoxycholic acid (UDCA) monotherapy with the combination therapy of UDCA plus prednisolone/azathioprine in primary biliary cirrhosis(PBC),and to investigate the risk factors affecting the therapeutic responses.Methods Eighty-two patients with untreated PBC were divided randomly into three groups.Group U (28 patients) received UDCA alone,group UP(27 patients) received UDCA and pr ednisolone,while group UA (27 patients ) received UDCA and azathioprine.The clinical and laboratory data were recorded after treated for 3,6 and 12 months.Repeated measures ANOVA and COX regression model were used for statistical analysis.Results Fatigue and pruritus were improved only in group UP(P=0.015 and P=0.037 respectively).Alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),gamma-glutamyl transferase (GGT),total bilirubin (TBIL),direct bilirubin (DBIL) and IgM in the 3 groups were decreased (P<0.05),while there was no statistical significant difference between the three groups (P>0.05).The patients with disease progression had higher Mayo risk score (MRS) (P=0.018) and prolonged prothrombin time (PT)(P=0.042).In group UP,side-effect associated with glucocorticosteroids occurred in eight patients while there was no side-effect in group U.High baseline levels of ALP、GGT and CHO were risk factors for biochemical remission(P=0.015).The increase of DBIL,TBIL,total bile acid(TBA) and PT did not contribute to the prediction of biochemical remission ( P=0.075 ).Conclusion There are no differences among the three groups in the improvement of hepatic biochemical data and IgM.The combination therapy of UDCA with prednisolone could relieve fatigue and itching.The disease of patients with higher Mayo risk score and prolonged PT tend to progress.High baseline levels of ALP,GGT and CHO are risk factors for biochemical remission.High baseline levels of TBIL,DBIL,TBA and PT could not predict biochemical remission.The incidence of adverse effect is lowest when treated with UDCA alone. 相似文献

107例自身免疫性肝炎及其重叠综合征患者的临床分析 总被引:6,自引:0,他引:6
目的 分析自身免疫性肝炎(AIH)77例及其重叠综合征患者30例的临床表现、免疫学及生物化学特点及其治疗方案.方法 164例自身免疫性肝病患者中,AIH患者77例和AIH胆汁性肝硬化(PBC)重叠综合征患者30例,分析患者的临床特点、生物化学及组织学变化和治疗应答反应等. 结果 AIH患者的发病年龄高峰在50岁左右,肝功能生物化学检查结果显示为肝炎样异常,丙种球蛋白和免疫球蛋白G均明显高于正常.74%的患者抗核抗体阳性,32%的患者抗平滑肌抗体阳性,52%的患者伴发了肝外自身免疫性疾病.肝组织病理变化以界面性肝炎为主(65%),在中、重度患者则出现小叶性肝炎、玫瑰花结样改变、桥接样坏死等.AIH-PBC重叠综合征患者血清ALT、AST、γ谷氨酰转移酶、碱性磷酸酶和抗核抗体、抗线粒体抗体(AMA)/AMA-M2阳性率较高,组织学检查往往还伴有胆管的病变.60例AIH患者接受免疫抑制剂强的松龙联合硫唑嘌呤治疗第1年时,AIH治疗患者达完全缓解者42例(70%),其中26例持续缓解,16例复发(激素减量至≤10 mg/d或停药后),10例部分缓解,8例无应答.持续缓解者的AST、ALT、免疫球蛋白G、丙种球蛋白及血总胆红素水平均显著低于非持续缓解者(34例,JD值均<0.05),此类患者撤除了硫唑嘌呤,单用激素的剂量均可维持在5~10 mg/d.AIH-PBC重叠综合征组经联合熊去氧胆酸治疗后除碱性磷酸酶和γ谷氨酰转移酶外,其余肝功能指标(ALT、AST、总胆红素)亦明显改善(P值均<0.01).结论 AIH及AIH-PBC重叠综合征在临床上并不少见,诊断需综合临床、生物化学、免疫学和病理学等检测结果.AIH患者联合应用糖皮质激素、硫唑嘌呤达持续缓解者,可改为单用小剂量激素治疗.AIH-PBC患者加用熊去氧胆酸治疗,亦可获得较好的疗效. 相似文献

Although the development of de novo autoimmune liver disease after liver transplantation(LT)has been described in both children and adults,autoimmune hepatitis(AIH)-primary biliary cirrhosis(PBC)overlap syndrome has rarely been seen in liver transplant recipients.Here,we report a 50-year-old man who underwent LT for decompensated liver disease secondary to alcoholic steatohepatitis.His liver function tests became markedly abnormal 8 years after LT.Standard autoimmune serological tests were positive for anti-nuclear and antimitochondrial antibodies,and a marked biochemical response was observed to a regimen consisting of prednisone and ursodeoxycholic acid added to maintain immunosuppressant tacrolimus.Liver biopsy showed moderate bile duct lesions and periportal lymphocytes infiltrating along with light fibrosis,which confirmed the diagnosis of AIH-PBC overlap syndrome.We believe that this may be a case of post-LT de novo AIH-PBC overlap syndrome;a novel type of autoimmune overlap syndrome. 相似文献

原发性胆汁性肝硬化(primary biliary cirrhosis,PBC)是一种肝脏特异的慢性进行性自身免疫性疾病,女性发病率较高,以肝内胆汁淤积为特征,血清多种自身免疫性抗体阳性,常并发其他自身免疫性疾病.至今为止,该病病因及发病机制仍不清楚,熊去氧胆酸(urodeoxycholic acid,UDCA)是美国食品药品监督管理局批准的惟一用于治疗PBC的一线药物,以13 ~ 15 mg.kg-1.d-1的剂量长期应用可有效改善PBC患者的生物化学指标,阻止或延缓PBC早期患者的组织学进展.
一、对UDCA应答的标准及意义
关于对UDCA的应答,欧洲肝病学组关于"胆汁淤积性疾病"中PBC治疗的指南给出了两种标准:巴黎标准[1][UDCA治疗1年后血清总胆红素≤17 μmO1/L、碱性磷酸酶(ALP)≤3倍正常值上限(ULN)、AST≤2×ULN]和巴塞罗那标准[2](UDCA治疗1年后ALP下降40%或降至正常),PBC患者用UDCA治疗1年后未达到上述两种标准之一可认为"对UDCA应答不佳".目前对反映UDCA治疗后患者生物化学应答的最佳标准仍存在争议,无论应用何种标准,对UDCA的应答状况都与其远期预后、生存率及肝硬化的进展程度密切相关. 相似文献

Long term outcome and response to therapy of primary biliary cirrhosis-autoimmune hepatitis overlap syndrome 总被引:5,自引:0,他引:5
BACKGROUND/AIMS: Whether primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome requires immunosuppressive therapy in addition to ursodeoxycholic acid (UDCA) is a controversial issue. METHODS: Seventeen patients with simultaneous form of strictly defined overlap were followed for 7.5 years. First-line treatment was UDCA alone (UDCA) in 11 and combination of immunosuppressors and UDCA (UDCA + IS) in 6. RESULTS: Characteristics at presentation were not significantly different between the 2 groups. In the UDCA + IS group (f-up 7.3 years), biochemical response in terms of AIH features (ALT<2ULN and IgG < 16 g/L) was achieved in 4/6 and fibrosis did not progress. In the UDCA group, biochemical response was observed in three patients together with stable or decreased fibrosis (f-up 4.5 years) whereas the eight others were non-responders with increased fibrosis in four (f-up 1.6 years). Seven of these eight patients subsequently received combined therapy for 3 years. Biochemical response was obtained in 6/7 and no further increase of fibrosis was demonstrated. Overall, fibrosis progression in non-cirrhotic patients occurred more frequently under UDCA monotherapy (4/8) than under combined therapy (0/6) (P = 0.04). CONCLUSIONS: Combination of UDCA and immunosuppressors appears to be the best therapeutic option for strictly defined PBC-AIH overlap syndrome. 相似文献

Autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) are two different liver diseases, however diagnosis criteria of these two affections can be found in a same patient. The aim of this study is to relate the clinical, serologic and histologic features of patients presenting the overlap syndrome, AIH-PBC, defined by the presence of at least of two main criteria of each disease and to evaluate their response to therapy. PATIENTS AND METHODS: This was a retrospective study concerning patients presenting overlap syndrome diagnosed between January 1998 and December 2001. These patients had been treated with ursodesoxycholic acid (AUDC) or prednisone and azathioprine or a combination of these three products. Clinical and biological criteria were used to assess response to therapy. RESULTS: Five patients fulfilled the diagnostic criteria of overlap syndrome. All patients were females, the median age was 38 years (range: 19-65 years). Three patients were treated by UDCA, a clinical and biological response was noted in only one patient. Two patients were treated by prednisone and azathioprine without any remission. Three patients were treated by a combination of these three products with a good response in two cases. CONCLUSION: Optimal treatment for overlap AIH-PBC syndrome remains to be determined. Treatment with UDCA or immunosuppressor alone is not efficient. A combination of these drugs should be evaluated in further studies. 相似文献

自身免疫性肝病(AILD)是一组以肝脏病理损害和肝功能异常为主要表现的自身免疫性疾病,可分为自身免疫性肝炎(AIH)、原发性胆汁性肝硬化(PBC)和原发性硬化性胆管炎(PSC),重叠综合征指同时具有其中两种疾病的临床和病理表现。重叠综合征相对少见,主要包括AIH—PBC和AIH—PSC。由于重叠综合征在临床表现、血清学和组织学方面综合了两种AILD的特点,其诊断和治疗有一定难度并存在争议。对其临床表现以及诊断和治疗方案进行深入研究有助于对该病的认识和防治。 相似文献
