چکیده
Background. There is a high prevalence of liver disease among the recipients of organs from donors with antibodies to hepatitis C virus (HCV). We undertook a study to determine the frequency of persistent HCV infection, as indicated by the presence of HCV RNA, among both cadaveric organ donors positive for antibodies to HCV (anti-HCV) and the recipients of organs from these donors. Methods. Serum samples from donors and recipients were tested for HCV RNA with the reverse transcriptase polymerase chain reaction, with use of primers from the 5' untranslated region of the HCV genome, and for anti-HCV with the first-generation enzyme-linked immunosorbent assay (ELISA) and two second-generation tests. Results. HCV RNA was detected in 9 of 11 organ donors (82 percent) with a positive first-generation ELISA for anti-HCV. Among the organ recipients, the prevalence of HCV RNA increased after transplantation: 7 of 26 patients (27 percent) had positive samples before transplantation, as compared with 23 of 24 patients (96 percent) after transplantation (P < 0.001). Among 13 recipients who were HCV RNAnegative before receiving organs from the nine HCV RNA-positive donors, HCV infection was detected in all 13 after transplantation, and anti-HCV developed in 8 (62 percent). On the basis of a positive test for HCV RNA, the maximal sensitivity of the three anti-HCV tests was 57 percent (positive in 4 of 7 patients with end-stage organ failure) before transplantation and 70 percent (positive in 16 of 23 patients) after transplantation. Conclusions. Nearly all the recipients of organs from anti-HCV-positive donors become infected with HCV. The current tests for anti-HCV antibodies underestimate the incidence of transmission and the prevalence of HCV infection among immunosuppressed organ recipients.

Hepatitis C infection is prevalent in candidates for and recipients of solid organ transplants. In the renal transplant population, HCV infection has been shown to decrease long-term patient and graft survival. The outcomes of HCV in recipients of other solid organ transplants are yet to be established and prospective studies will be needed in the future. In the absence of effective and safe an...
متن کاملHepatitis E in Children: A Position Paper by the ESPGHAN Hepatology Committee.
BACKGROUND Hepatitis E virus (HEV) is endemic in large parts of the developing world. Waterborne transmission of genotypes 1 or 2 commonly causes acute hepatitis, which is usually self-limited in healthy individuals. In addition, acute HEV infections also occur outside endemic areas, mostly related to foodborne transmission of HEV genotype 3. A growing number of publications in the last decade ...

Hepatitis C is, at present, a worldwide health problem and is the most common cause of liver transplantation. Its prevalence in pregnant women is similar to that of the general population. In the absence of cirrhosis and portal hypertension, most HCV-infected pregnant women do not have obstetric complications. Screening of pregnant women that are asymptomatic and do not have risk factors is not...

Chronic hepatitis C (CHC) is caused by hepatitis C virus (HCV) infection. HCV infection causes acute hepatitis, and the majority of those infected progress to chronic hepatitis, and some of them develop cirrhosis and hepatocellular carcinoma. Transmission of HCV is parenteral, and the major transmission routes include drug abuse, insecure injections or medical procedures, contaminated syringes ...
