Family study of monozygotic twins affected by pemphigus vulgaris

Rare are the family studies that include siblings affected by pemphigus vulgaris (PV) and in whom HLA class II alleles are related. HLA-DR and -DQ genotyping and profiling of antibodies against desmogleins (Dsg) 1 and Dsg3 were performed in ten members of a family including monozygotic twins affected by PV. The twin sisters were heterozygotes; they presented the haplotypes most commonly associated with increased susceptibility to PV (DRB1104:02-DQA1103:01-DQB1103:02 and DRB1114:04-DQA1101:01-DQB1105:03). Their parents and five siblings had only one or none of these two haplotypes in combination with the alleles or haplotypes associated with resistance to PV (DRB1107:01-DQA1102:01-DQB1102:02 and DRB1113:01-DQA1101:03-DQB1106:03). Only the monozygotic twins presented IgG antibodies against both Dsg1 and Dsg3. According to our knowledge based on a review of published literature on the topic, this is the first report of PV affecting monozygotic twins.     

Changes due to cooking and sterilization in low molecular weight carbohydrates in immature seeds of five cultivars of common bean

Immature seeds of five bean cultivars (flageolet-type and those intended for dry-seed production) were assessed for changes in water-soluble carbohydrates including raffinose family oligosaccharides (RFOs) due to boiling, sterilization, and storage of the sterilized product. About 100?g fresh weight of edible portion of fresh bean seeds contained 2449.3–3182.6?mg total soluble sugars, of which RFOs comprised 44–49%. The highest amounts of these compounds were found in the seeds of the cultivars Laponia and Mona. The dominant oligosaccharide was stachyose. Boiling fresh seeds to consumption consistency reduced total soluble sugars and RFOs: average values were 57% and 55%, respectively. Sterilization in cans resulted in 65% reductions of both total soluble sugars and RFOs. In general, there were no changes in the content of soluble sugars in canned and sterilized products stored for 12?months.     

A single nucleotide polymorphism −35 kb T > C (rs9264942) is strongly associated with psoriasis vulgaris depending on HLA-Cw06

HLA class I molecules play a role both in viral infection control and in autoimmune diseases development. rs9264942T > C polymorphism in HLA-C gene was found to impact on HLA-C surface expression level and to be associated with HIV-1 control. It was found that these HLA alleles which protect against AIDS are associated with autoimmune disease e.g. psoriasis vulgaris (PsV). Whether rs9264942 SNP is associated with PsV was investigated here. rs9264942T > C was genotyped in 292 PsV patients, and 254 controls using TaqMan Genotyping Assay.     

In vitro study on the removal of pemphigus antibody with immunoadsorption

The adsorbability of pemphigus vulgaris (PV) antibodies to immunoadsorbent with phenylalanine, tryptophan, and dextran sulfate as ligands was examined, PV antibodies were adsorbed to immunoadsorbents with both phenylalanine and tryptophan as ligands, in batchwise adsorption and column adsorption. PV antibodies were not adsorbed to immunoadsorbent with dextran sulfate as ligand, in column adsorption. It was also shown that the rates of decrease of normal protein fractions in column adsorption with phenylalanine as a ligand were small. Our results suggest that immunoadsorption therapy using sorbent with phenylalanine as a ligand may be useful for the treatment of PV. © 1996 Wiley-Liss, Inc.     

高通量测序分析重度寻常痤疮患者和健康人肠道菌群差异

目的 利用高通量测序技术分析重度寻常痤疮患者和健康人肠道菌群的差异.方法 门诊确诊的重度寻常痤疮患者10例及年龄、性别相匹配的健康人10例,分别收集粪便标本,提取细菌DNA,行16S rRNA测序鉴定微生物的种类,并进行菌群差异分析.结果 两组肠道菌群多样性未发现显著差异,仅在肠道菌群的相对丰度上发现个别具有显著差异的菌.两组标本主要由拟杆菌门、厚壁菌门、变形菌门、放线菌门组成.比较两组在门、属水平上菌群相对丰度,差异均无统计学意义;在种水平上,Blautia producta、Coprococcus eutactus在两组间差异有统计学意义.结论 重度寻常痤疮患者和健康人相比,菌群多样性指数未见明显差异.但某些细菌菌种存在显著差异.
