ABSTRACT— One hundred and twenty-seven patients with histologically verified chronic non-A, non-B hepatitis were followed for up to 23 years (mean 6.3 years). Thirty-nine were infected by blood transfusion, 58 were drug-addicts and 30 had no obvious source of infection. Chronic persistent hepatitis (CPH) was diagnosed in 84 (66%), while 43 patients (34%) had chronic active hepatitis (CAH) with or without cirrhosis. Patients with CPH were significantly younger (29.7 years vs 46.8 years; p<0.01), irrespective of the type of virus exposure. Antibodies to hepatitis C virus (anti-HCV) were detectable in 91 patients (72%) and 36 (28%) were anti-HCV negative. Fifteen patients with acute onset, and negative for anti-HCV at the start, became positive during follow-up; 12 of them within 4.5 months. We found no differences among anti-HCV positive and anti-HCV negative patients in liver function tests, resolving rate, morphological progression in serial biopsies or mortality rate. Five previously anti-HCV positive patients became negative during follow-up and in two of them this was accompanied by decreasing hepatic inflammation.  相似文献

To clarify the relationship between autoimmune hepatitis (AIH) and the hepatitis C virus (HCV), we investigated the prevalence of antibodies to HCV (anti-HCV) by an enzyme-linked immunosorbent assay in patients with AIH, primary biliary cirrhosis (PBC), rheumatoid arthritis and multiple myeloma. The antibody was detected in 9 out of 18 patients with AIH (50%), in 3 out of 23 with PBC (23%), in 2 out of 10 with rheumatoid arthritis (20% ), and in 5 out of 9 with multiple myeloma (56% ). However, the optical density values in these patients were lower than those observed in non-A, non-B hepatitis (NANBH). Anti-HCV became negative immediately after the initiation of glucocorticoid therapy in all four antibodypositive AIH patients tested. The extracted immunoglobulin G fraction from sera of 5 anti-HCV negative AIH patients became positive for the antibody. This phenomenon was not observed in 5 normal volunteer sera. The 9 family members of three anti-HCV positive AIH patients showed no anti-HCV positivity. These results suggest that autoantibodies in AIH patients may cross-react with the HCV -related antigen. Direct association of the HCV influencing the development of AIH is unlikely. Therefore, care should be taken in the evaluation of anti-HCV positivity in patients with autoimmune diseases and multiple myeloma. This study was supported by the Ministry of Health, Science and Welfare of Japan.  相似文献

To determine whether identification of subclasses of anti-HCV IgG would help distinguish between acute and fulminant hepatitis, we assayed serum IgG subclasses of anti-HCV (C100-3) in non-A, non-B hepatitis. Anti-HCV IgG was restricted to two subclasses in different diagnostic conditions; anti-HCV IgGl and anti-HCV IgG3. Anti-HCV IgGl was the main subclass in acute hepatitis (AH), and was positive in all the cases and only one case was positive for anti-HCV IgG3. Anti-HCV IgG3 was the dominant subclass in fulminant hepatitis (FH). Out of the total 12 cases of FH, who were positive for either anti-HCV IgG or for any of it’s subclasses, in 10 cases (83%), anti-HCV IgG3 had higher optical density (OD) values than anti-HCV IgGl and in 6 cases (50%) was the only subclass of anti-HCV IgG being positive. In 5 cases with FH, anti-HCV IgG3 became positive even when anti-HCV IgG was negative. These findings form the basis of a new observation and are likely to be helpful in the diagnosis of non-A, non-B fulminant hepatitis. This study was supported by a Grant-in-Aid for Scientific Research from viral Hepatitis and Research Foundation of Japan, 1991.  相似文献

Hepatitis C virus is the most frequent cause of chronic non-A, non-B hepatitis, and the antibodies to structural and nonstructural proteins encoded by viral genome have been suggested to be markers of ongoing HCV infection. We studied the behavior of these antibodies during interferon therapy in 18 patients with chronic hepatitis C and also during a follow-up period of at least four years. A significant decrease of anti-HCV titer was found only in patients who had shown positive response to therapy and all of them were anti-HCV negative at the end of follow-up. Analysis by recombinant immunoblotting assay showed that only anti-c100 were affected by interferon therapy, whereas anti-c22 and anti-c33 were not modified. Using polymerase chain reaction to detect small amounts of HCV genome in serum, we could confirm that the behavior of HCV-RNA during and after interferon therapy is similar to that of anti-HCV and the loss of anti-c100 seems to be closely related to HCV-RNA disappearance from serum. Our patients with chronic hepatitis C were found to be of type 1b and 2, according to the recent score of Simmonds, and the clearance of serum HCV-RNA during treatment and its sustained negative status are closely related to genotype 2 and to long-term positive response to interferon.  相似文献

We describe a case of a 33-year-old female patient with chronic hepatitis B who developed type 1 diabetes mellitus (DM) after a 13-mo period of treatment with recombinant human interferon-alpha (IFN-α) 2b. The patient presented with polydipsia, polyuria, hypergly-cemia, diabetic ketoacidosis, combined with C-peptide secretion defi ciency and positive islet cell autoantibody (ICAb). IFN-α 2b treatment was terminated and in-stead insulin treatment was initiated. Five months after cessation of the recombinant human IFN-α 2b therapy, the patient remained insulin-dependent. Her serum HBV DNA became negative and serum transaminase returned to the normal level after a 10-mo period of IFN therapy. Type 1 DM induced by IFN-α is relatively rare in patients with chronic hepatitis B. We should pay more attention to patients on IFN-α therapy to avoid destruction of pancreatic beta cells. This is the first case report from China.  相似文献

One hundred and thirty-five patients who developed non-A, non-B post-transfusion hepatitis mostly after cardiac surgery, were followed for a mean (±S.D.) of 90±41 months (range: 13–180) to evaluate clinical and histological outcome.Thirty-one cases resolved within 12 months, while 104 (77%) progressed to chronicity. Twenty-one of 65 (32%) biopsied patients developed cirrhosis at the end of the follow-up, and one further progressed to hepatocellular carcinoma. One patient had a complete histological remission (1%). The remaining cases had chronic active (37%), chronic persistent (27%) or chronic lobular hepatitis (3%). About half of the cases with cirrhosis developed portal hypertension, and three of these died due to esophageal varices hemorrhage, one due to liver failure, and one due to hepatocellular carcinoma. Out of 26 patients with the initial histologic diagnosis of chronic hepatitis that were rebiopsied during follow-up, 13 (50%) progressed to cirrhosis. These patients were significantly older than patients who did not develop cirrhosis (mean age 57 and 45 years respectively; p<0.01).During acute hepatitis anti-HCV was positive in all but one of the 114 patients tested. Percentages were similar for patients who recovered (95%) and those who developed chronic hepatitis (100%). However, during follow-up, 71% of the 1st generation and 21% of the 2nd generation ELISA test patients with acute resolved hepatitis became anti-HCV negative, while the same figures in chronic cases were only 8.5% (p<0.0001) and 1.4% (p=0.012). This suggests a correlation between anti-HCV antibody activity, hepatitis C virus replication, and the development of chronic liver disease.  相似文献

Anti-hepatitis C virus (HCV) immunoglobulin M antibody titres were measured by an enzyme-linked immunosorbent assay method in 16 patients with non-A, non-B acute hepatitis (NANB AH), 13 with non-A, non-B fulminant hepatitis (NANB FH) and nine with type C chronic hepatitis. Anti-HCV IgM was positive in one of the 16 patients with NANB AH, six of the 13 with NANB FH, and five of the nine with type C chronic hepatitis. Anti-HCV IgG was positive in eight of the 16 patients with NANB AH and eight of the 13 with NANB FH. Either anti-HCV IgM or anti-HCV IgG were positive in 10 of the 13 patients with NANB FH. All of the five anti-HCV IgM positive patients with type C chronic hepatitis were undergoing an exacerbation of the diseases, while all of the anti-HCV IgM negative patients were in a remission stage which had lasted for more than 6 months. The findings of this study suggest that anti-HCV IgM is useful for the early diagnosis of type C FH and may be a useful marker of diseases activity in type C chronic hepatitis.  相似文献
