Paternal mosaicism and hereditary angioedema in a Taiwanese family.

BACKGROUND: Hereditary angioedema (HAE) is a rare disorder characterized by recurrent attacks of localized subcutaneous or submucosal edema. It is inherited in an autosomal dominant fashion and caused by a deficiency of C1 inhibitor (C1 INH). Most patients with HAE have an absolute deficiency of C1 INH (type I HAE), whereas the rest (approximately 15%) synthesize a dysfunctional C1 INH protein (type II HAE). Mosaicism is rare in HAE. OBJECTIVE: To describe the clinical manifestations, laboratory findings, and molecular genetic studies in a Taiwanese family with type I HAE with paternal mosaicism. METHODS: A family that included a 34-year-old man (index patient) and his 25-year-old brother who both had recurrent peripheral angioedema was evaluated. A younger sister had died of an unexplained cause at 18 years of age. We analyzed blood levels of C3, C4, and C1 INH and sequenced the SERPING] (C1NH) gene that codes for C1 INH in 5 family members, including the parents and 3 brothers. RESULTS: The 4 men in the family had a novel mutation c.3_73del, p.N1fsX34 in exon 3 of the C1INH gene, resulting in C1 INH deficiency. Although the father carried this mutant gene, he had normal serum levels of C1 INH. Based on quantitative analysis of allele dosage by DNA fragment analysis (GeneScan), the father was determined to have genetic mosaicism. CONCLUSION: Parental mosaicism is a possible explanation for normal C1 INH plasma concentrations in both parents despite clinically apparent HAE in the children.

Analysis of proteins and lipopolysaccharides from Chinese isolates of Coxiella burnetii with monoclonal antibodies.

Four Coxiella burnetii isolates in China and two reference strains were compared by SDS-PAGE and immunoblotting. The SDS-PAGE profiles of whole cells and LPS of Chinese isolates Qiyi, Xinqiao, and YS-8 were found closely related to Henzerling strain, and different from the Grita strain. In immunoblot assay of LPS and proteinase K-digested whole rickettsiae minor differences were seen in polysaccharide structure among the Chinese isolates by phase I monoclonal antibody. The present results suggest that the strains reported here may be divided into three groups according to the polysaccharide structure: Xinqiao and Henzerling strains (1), YS-8 and Grita (2), and Qiyi (3).

思美泰治疗妊娠胆汁淤积症的疗效观察

妊娠胆汁淤积症(ICP)是一种在妊娠期出现的以皮肤搔痒和黄疸为特征的较常见的并发症, 易导致早产、胎儿窘迫、死胎、新生儿死亡及产后出血等,严重影响围产儿安 全。思美泰是一种治疗ICP的新药,疗效显著。现将1998年10月～2000年10月收治的60例ICP 随机应用思美泰和门冬氨酸钾镁治疗,报道如下： 1　资料和方法 1.1　临床资料来源 　　60例ICP均为本院住院病人,年龄22～35岁,平均26.7岁,初产妇52人,经产妇8人,均有皮 肤搔痒和肝功能异常,肝类病原学指标全部阴性,并排除妊高征肝损,急性脂肪肝及药物性 肝炎。随机分为2组,2组病例年龄、病情、肝功能损害程度和孕周无显著差异。 1.2　治疗方案 　　治疗组采用德国基诺药厂生产的思美泰注射液1g,由稀释液溶解加入5%葡萄糖注射液250ml 中静滴,每日1次,持续4周。对照组采用杭州民生药厂生产的门冬氨酸钾镁注射液30ml加入 5%葡萄糖注射液250ml中静滴,每日1次,持续4周。2组基础药物相同,包括Vitc、复方益 肝灵及中药茵陈汤。 1.3　疗效判断 　　疗效判断标准分为3组：①显效：用药后患者症状、体征明显改善,生化(谷丙转氨酶、总 胆红素、总胆汁酸)恢复正常或降至治疗前基础的50%以上;②有效：症状体征改善,生化指 标有下降,但未降至基础的50%;③无效：症状体征及生化指标没有改善或有加重者。显效 和有效合计称为有效病例,据此计算有效率。
