Four monoclonals, each specific for a single IgG subclass, were chosen for their good reactivity. In 19 typhoid and non-typhoid serum samples, the sum of the ELISA values obtained with the four subclass-specific monoclonals was highly correlated with the ELISA values obtained with a monoclonal anti-total IgG. Moreover, there was no competition among the various IgG subclasses of anti-LPS antibodies. These data indicate that the subclass distribution of IgG anti-LPS antibodies, calculated on the basis of ELISA values in the subclass-specific assays, is likely to reflect the actual distribution of the different subclasses in whole serum. Different subclass patterns of IgG anti-LPS antibodies were observed in serum samples from 11 patients with typhoid fever, with IgG1 and IgG2 being the most represented subclasses. The ELISA method described here will be useful to elucidate the factors that influence the anti-LPS subclass profile during the humoral immune response to Salmonella typhi.</p>","PeriodicalId":75613,"journal":{"name":"Bollettino dell'Istituto sieroterapico milanese","volume":"68 3","pages":"234-40"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13638214","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}

Matteo, IRCCS, Pavia (referral Center for hepatitis in our district: 502534 inhabitants) we observed 4238 patients (2706 M = 63.8%; 1532 F = 36.2%) admitted with presumptive diagnosis of hepatitis. The male to female sex ratio was 1.78 and average age was 38 (1-90) years. Acute viral hepatitis was diagnosed in 3238 patients (76.4%), 1960 of which were males (60.5%) and 1278 (39.5%) females, with an average age of 35 (1-88) years. The possible route of transmission was: drug addition in 487 patients (15%), blood transfusion in 464 (14.3%), other (sexual, professional, familiar) in 332 (10.3%), unknown in 1955 (60.4%). Chronic hepatitis (CH) was diagnosed according to the European Association for the Study of the Liver (EASL) and to the International Association for the Study of the Liver (IASL) in 848 patients (20%), 704 M(83%) and 144 F (17%) with an average age of 48 (2-90) years. 463 patients (54.5%) were biopsied during admission, 385 (45.5%) received definitive diagnosis by clinical and previous histologic records. CAH was found in 268 (57.9%), CPH in 161 (34.8%) and CLH in 20 (4.3%) patients. Other liver diseases (steatosis, cirrhosis, HCC) were identified in 152 subjects (3%). The prevalence of A, B, NANB and Delta hepatitis virus and HI virus in the acute disease was respectively of 5.4%, 54.8%, 33.9%, 0.28% and 0.77%. In CH the HBV aetiology accounted for 49.1%, NANB virus for 44.5%, co/super infection with HDV for 15%. Among factors involved in pathogenesis of chronic hepatitis we focused attention on drug addition which was found in 129 (28.7%) patients, blood transfusion in 70 (15.6%), HIV infection in 35 of 166 (21.1%). The data still demonstrate the high prevalence of HBV aetiology of CH and existence of co-factors in the pathogenesis of chronicity.
