The biochemical characterization of the protein component of the deposits provides a powerful system of classification for the different amyloidotic disorders and shades light on the molecular mechanisms of selective precipitation from soluble precursors and of tissue-specific deposition. Furthermore, identification and analysis of the genes coding for the precursors, and clarification of the kind of inheritance in some familial forms of amyloidosis, make prevention through genetic counselling and predictive diagnosis possible.</p>","PeriodicalId":76092,"journal":{"name":"La Ricerca in clinica e in laboratorio","volume":"19 1","pages":"27-38"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02871789","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13811814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method can detect HBeAg in immune complexes whether antigen or antibody is in excess. In the chronic phase of HBV infection, HBeAg/anti-HBe complexes are formed transiently in the course of the disease, unrelated to the phases of virus replication or peaks of hepatocytolysis, or to the histologic picture of liver disease. Our study indicates that this method offers a new approach to the understanding of biological and clinical problems of the HBeAg/anti-HBe antigenic system in chronic HBV infection.</p>","PeriodicalId":76092,"journal":{"name":"La Ricerca in clinica e in laboratorio","volume":"19 1","pages":"81-91"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02871796","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13903525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey, based on 74 unrelated kindreds, revealed that antithrombin III, protein C and protein S defects are the most frequent genetic disorders. Venous thromboembolism was more frequent than arterial thrombosis, which was seen in only a minority of cases, most frequently with dysfibrinogenemia. About half of the patients developed venous thrombosis with a similar incidence in antithrombin III, protein S and protein C defects. About half of the symptomatic patients had recurrences and 40% developed thrombosis after a triggering factor, most frequently after surgery, during the puerperium, pregnancy, oral contraceptive intake or bed rest. Deep venous thrombosis prevailed and superficial thrombophlebitis was rare in antithrombin III-deficient patients, whereas deep venous thrombosis was present in about half and superficial thrombophlebitis in about one third of the cases with protein S and protein C defects. The probability to be free of thrombosis decreases with increasing age and at 35 years can be estimated to be 47% both for men and women. There is, however, a group of patients who are still free of thrombosis despite their older ages.</p>","PeriodicalId":76092,"journal":{"name":"La Ricerca in clinica e in laboratorio","volume":"19 1","pages":"67-74"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02871794","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13671265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
