庚型肝炎病毒感染对慢性丙型肝炎的影响 总被引:1,自引:0,他引:1
研究慢性丙型肝炎患者中庚型肝炎病毒(UGV)的感染及其对丙型肝炎临床表现、肝功能和对干扰素应答的影响。以HGV的5′非编码区引物建立了检测HGV RNA的RT-PCR法,检测51例慢性丙型肝炎病人中的HGV感染。结果51例病人中,11例为HGV RNA阳性。慢性丙型肝炎病人的临床表现与是否感染HGV不相关,肝功能试验结果也无统计学差异。29例接受干扰素治疗的病人中,有6例病人(20.7%)合并HGV感染。HGV阳性组6人中1例完全应答,HGV阴性组23人中,有3例完全应答,在这有限的病例中,两组应答率没有统计学差异。提示在我国丙型肝炎病人中,混合HGV较为常见,HGV感染对丙型肝炎的临床表现无明显影响,也不影响其对干扰素的应答。 相似文献

We evaluated the prevalence of hepatitis C virus (HCV) infection in Italian patients suffering from fibromyalgia (FM), in
comparison with patients affected by non-HCV related rheumatic degenerative disorders. Consecutive patients with FM and a
statistically comparable group of patients suffering from peripheral osteoarthritis (OA) or sciatica due to L4-L5 or L5-S1
herniated disc were tested for HCV infection with a third-generation microparticle enzyme immunoassay (MEIA). In the positive
cases, a third-generation recombinant immunoblot assay (RIBA) confirmatory test and serum HCV-RNA test were performed. Fisher’s
exact test was performed to compare the prevalence of HCV infection (MEIA- and RIBA-positive results) obtained in the two
enrolled groups. Enrolled were 152 subjects suffering from FM and 152 patients with peripheral OA or sciatica. Anti-HCV antibodies
were found in 7/152 (4.6%) patients suffering from FM and in 5/152 (3.3%) of control subjects. No statistically significant
differences in HCV prevalence were detected between cases and controls. Our present report does not confirm previous data
indicating an increased prevalence of HCV in FM patients and does not seem to support a significant pathogenetic role of HCV
under this condition. 相似文献

肝炎病毒感染与胰岛素抵抗 总被引:3,自引:0,他引:3
肝炎病毒慢性持续感染主要是由乙型肝炎病毒(HBV)和丙型肝炎病毒(HCV)所致, 除了引起肝脏损害外, 还与一些肝外组织的损害密切相关. 近年来, 研究资料显示慢性HCV和HBV感染与糖尿病和脂肪肝等代谢性疾病的发病密切相关, 而胰岛素抵抗(IR)可能是其发病机制的中心环节. IR也是肝纤维化进展的相关因素, 并影响慢性肝炎病毒感染时抗病毒治疗的疗效. 此外, 糖尿病还可能增加肝炎病毒致癌的作用, 应该引起肝病医师的高度重视. 本文就近年来对HCV和HBV感染中IR发生机制方面的研究, IR在HCV和HBV感染相关的糖尿病和脂肪肝中的作用和影响及其对临床的指导意义作一述评. 相似文献

Hepatitis G virus RNA and its relation to hepatitis C infection in adult haemophilic patients 总被引:2,自引:0,他引:2
C. Y. W. Tong T. A. Sallam H. Williams K. J. Mutton I. T. Gilmore & C. H. Toh 《British journal of haematology》1997,99(2):295-297
The prevalence of hepatitis C virus (HCV) infection and hepatitis G virus (HGV) RNA were studied in 50 adult haemophilic patients who had received commercial clotting factors prior to 1980. HGV RNA was detectable in 6/50 patients (12%); 49/50 (98%) had antibody to HCV and 40/49 (82%) of these were viraemic with detectable HCV RNA; 5/6 patients with detectable HGV RNA had co-existing HCV infection and viraemia. The HGV PCR products from all six patients were directly sequenced and all were shown to be similar to that of HGV but more diverse from that of GB virus C. One patient who had persistent abnormal liver function tests had detectable HGV RNA but no evidence of hepatitis B or C. The presence of HGV RNA in the absence of hepatitis B and C infection indicates that this virus is capable of independent transmission. Independent response to interferon was demonstrated in one patient with co-infection who lost HGV but not HCV after interferon therapy. 相似文献

A number of new hepatitis viruses (G, TT, SEN) were discovered late in the past century. We review the data available in the literature and our own findings suggesting that the new hepatitis G virus (HGV), disclosed in the late 1990s, has been rather well studied. Analysis of many studies dealing with HGV mainly suggests the lymphotropicity of this virus. HGV or GBV-C has been ascertained to influence course and prognosis in the HIV-infected patient. Until now, the frequent presence of GBV-C in coinfections, hematological diseases, and biliary pathology gives no grounds to determine it as an "accidental tourist" that is of no significance. The similarity in properties of GBV-C and hepatitis C virus (HCV) offers the possibility of using HGV, and its induced experimental infection, as a model to study hepatitis C and to develop a hepatitis C vaccine. 相似文献

Eighty-two patients with bleeding disorders registered with our centre were screened for infection with hepatitis G virus (HGV). 80 patients were positive for hepatitis C (HCV) antibodies, 66 of whom (83%) were HCV PCR positive. 11 patients (13%) were HGV RNA-positive, a similar prevalence rate to that of other studies of patients with bleeding disorders who received factor concentrates prior to the introduction of viral inactivation procedures. There was no significant difference in histological activity index (HAI) between the 10 HGV RNA-positive and the 31 HGV RNA-negative patients who underwent liver biopsy for assessment of HCV infection (median HAI scores 5.5, range 2–10 and four, range 0–10 respectively, P = 0.07). One patient in each group had established cirrhosis. In patients who underwent HCV quantitation there was no significant difference in HCV viral titre between HGV RNA-positive and negative patients (median HCV titre in HGV RNA-positive patients 2.10 × 105 DNA copies /ml ( n = 8) range 4.17 × 102 to 4.17 × 106 , median HCV titre in HGV RNA-negative patients 3.33 × 105 ( n = 31) range 1.00 × 103 to 6.67 × 106 , P = 0.68). In this study there was no evidence that individuals co-infected with HGV and HCV have more severe liver disease than those infected with HCV alone. 相似文献
