探讨不同亚型Wilson’s病(WD)的临床特点及肝型患者预后转归。方法收集256例WD患者的临床资料并随访,根据临床表现将患者分为不同的临床亚型,进一步分析比较肝型、脑型和混合型WD患者的临床特点差异和随访追踪肝型WD患者的预后。结果在256例WD患者中,以混合型(152例,59.4%)和肝型(74例,28.9%)患者常见,而脑型(27例,10.5%)和其他亚型(3例,1.2%)较少;肝型WD患者失代偿期肝硬化比例(78.4%)高于混合型患者(22.0%,P〈0.001);肝型WD患者肝脏血清生化学指标(转氨酶、ALP、GGT、胆红素以及球蛋白水平)高于混合型WD患者(P〈0.05);肝型WD患者血清铜[(1.04±1.50) mg/L]水平明显低于脑型WD患者[(2.96±2.88) mg/L]和混合型WD患者[(2.34±2.68) mg/L,P〈0.001],但两者铜蓝蛋白和尿铜水平无统计学差异(P〉0.05);肝型WD患者K-F环检出率(64.9%)低于脑型WD患者(92.6%)和混合型WD患者(90.1%,P〈0.05);经Logistic回归分析显示角膜K-F的有无与年龄(OR=0.922,P=0.014)、血清铜蓝蛋白(OR=35902.1,P=0.015)相关;平均随访31例肝型WD患者(8.3±5.8)年,3例(9.7%)进展为混合型WD患者。结论 WD以混合型和肝型最多见,肝型患者肝脏损害比混合型更为严重,提示肝脏是WD最主要的靶器官。 相似文献

目的 观察肝豆状核变性(WD)伴黄疸患者的临床特征,探讨肝豆状核变性黄疸患者临床鉴别诊断的侧重点。方法 回顾性分析52例以“黄疸待查”初次入院的WD患者的临床资料,包括临床表现和常规实验室指标的变化。采用序列分析法检测全血基因组8、12、13、16外显子的突变情况。结果 本研究纳入WD患者24例和慢性乙型肝炎重度患者28例。WD患者发病中位年龄(33.2岁)显著低于乙型肝炎(41.8岁,P=0.049),WD患者自起病至明确诊断的中位时间(8.2月)显著长于乙型肝炎(1月,P<0.001);WD患者24 h尿铜水平(919.83±1017.15 μg)显著高于乙型肝炎(204.79±191.85 μg,P<0.001);WD患者血清γ-谷氨酰转肽酶水平(175.74±245.99 U/L)显著高于乙型肝炎(133.44±115.95 U/L,P=0.004),且与24 h尿铜水平呈正相关(r=0.552,P=0.012);24例WD患者全部,而仅4例乙型肝炎患者可检出ATP7B突变。结论 肝豆状核变性伴黄疸患者除可利用血清铜、铜蓝蛋白检测进行筛选性诊断外,24 h尿铜检测为重要的鉴别诊断指标,而血清γ-谷氨酰转肽酶可能是该病潜在的诊断指标。 相似文献

AIM: To investigate the prevalence of the ATP7B gene mutation in patients with hepatic presentation of Wilson's disease (WD) in Lithuania. METHODS: Eleven unrelated Lithuanian families, including 13 WD patients were tested. Clinically WD diagnosis was established in accordance to the Leipzig scoring system. Genomic DNA was extracted from whole venous blood using a salt precipitation method. Firstly, the semi-nested polymerase chain reaction (PCR) technique was used to detect the c.3207C〉A (p.H1069Q) mutation. Patients not homozygous for the c.3207C〉A (p.H1069Q) mutation were further analyzed. The 21 exons of the WD gene were amplified in a thermal cycler (Biometra T3 Thermocycler, G0ttingen, Germany). Direct sequencing of the amplified PCR products was performed by cycle sequencing using fluorescent dye terminators in an automatic sequencer (Applied Biosystems, Darmstadt, Germany). RESULTS: Total of 13 WD patients (mean age 26.4 years; range 17-40; male/female 3/10) presented with hepatic disorders and 16 their first degree relatives (including 12 siblings) were studied. Some of WD patients, in addition to hepatic symptoms, have had extrahepatic disorders (hemolytic anemia 3; Fanconi syndrome 1; neurophsychiatric and behavioural disorder 2). Liver biopsy specimens were available in all of 13 WD patients (8 had cirrhosis; 1-chronic hepatitis; 3-acute liver failure, 1-1iver steatosis). Twelve of 13 (92.3%) WD patients had the c.3207C〉A (p.HI069Q) mutation, 6 of them in both chromosomes, 6 were presented as compound heterozygotes with additional c.3472-82delGGTTTAACCAT, c.3402delC, c.3121C〉T (p.RI041W) or unknown mutations. For one patient with liver cirrhosis and psychiatric disorder (Leipzig score 6), no mutations were found. Out of 16 first degree WD relatives, 11 (68.7%) were heterozygous for the c.3207C〉A (p.H1069Q) mutation. Two patients with fulminant WD died from acute liver failure and ii are in full remission under peniciilam 相似文献

AIM: To study the genotype phenotype correlation in Wilson's disease (WD) patients within families. METHODS: We report four unrelated families from South India with nine members affected with WD. Phenotype was classified as per international consensus phenotypic classifi cation of WD. DNA was extracted from peripheral blood and 21 exons of ATP7B gene and flanking introns were amplified by polymerase chain reaction (PCR). The PCR products were screened for mutations and the aberrant products noted on screening were sequenced. RESULTS: Four separate ATP7B mutations were found in the four families. ATP7B mutations were identical amongst affected members within each family. Three families had homozygous mutations of ATP7B gene while one family had compound heterozygous mutation, of which only one mutation was identifi ed. We noted concordance between ATP7B gene mutation and Wilson's disease phenotype amongst members within each family. The age of onset of symptoms or of detection of asymptomatic disease, baseline serum ceruloplasmin and baseline urinary copper levels were also similar in affected members of each family. Minor differences in phenotype and baseline serum ceruloplasmin level were noted in one family.CONCLUSION: We report concordance between ATP7B mutation and WD phenotype within each family with 〉 1 member affected with WD. Homozygous ATP7B mutation was present in 3 of the 4 families studied. Our report supports allelic dominance as a determinant of WD phenotype. However, in one family with compound heterozygous mutation, there was a similar WD phenotype which suggests that there may be other factors determining the phenotype. 相似文献
