Popis: Hepatitis C infection (HCV) is more prevalent in patients who have received kidney transplants than in the general population but the morbidity and mortality associated with infection in this group is unclear. Sera taken from 36 renal transplant recipients with chronic liver dysfunction and from 42 with normal liver function were tested for HCV infection by second generation ELISA (Abbott Laboratories) and second generation recombinant immunoblot assay (Chiron Corporation) (RIBA-2). Evidence of HCV replication was sought by reverse transcription poly-merase chain reaction (RT PCR) using primers from the 5′ nontranslated region (5′NTR). Infection was detected in 20/36 (54%) and in 2/42 (4.8%) controls (P < 0.01). Twelve liver dysfunction patients were positive by all three tests, six were positive by ELISA and RT PCR but had indeterminate RIBA-2, one was positive by ELISA and RIBA but negative by RT PCR, and one was positive only by RT PCR. Of two infected control patients, one was positive by all three tests and one who was later found to have been in the early stage of infection was positive only by RT PCR. Follow-up of infected patients showed persistence of viraemia in 14/15 (93%). Evidence of infection with different types of HCV was shown by the lack of amplification by RT PCR by primers with mismatching bases with HCV types 2 and 3. It is concluded that in our renal transplant patients, chronic HCV infection is usually associated with liver dysfunction and persistent infection is common. © 1994 Wiiey-Liss, Inc.
