<b>Background and Objectives: </b> There are few reports on hepatitis C virus genotype 4 (HCV-4) recurrences after orthotopic liver transplantation (OLT). Therefore, we undertook a study to determine the epidemiological, clinical and virological characteristics of patients with biopsy-proven recurrent HCV infection and analyzed the factors that influence recurrent disease severity. We also compared disease recurrence and outcomes between HCV-4 and other genotypes. <b> Patients and Methods: </b> All patients who underwent OLT (locally or abroad) for HCV related hepatic cir--<i> rhosis from 1991 to 2006 and had recurrent HCV infection were identified. Clinical, laboratory and pathological data before and after OLT were collected and analyzed. </i> Results: Of 116 patients who underwent OLT for hepatitis C, 46 (39.7&#x0025;) patients satisfied the criteria of recur--rent hepatitis C. Twenty-nine (63&#x0025;) patients were infected with HCV genotype 4. Mean (SD) for age was 54.9 (10.9) years. Nineteen of the HCV genotype 4 patients (65.5&#x0025;) were males, 21 (72.4&#x0025;) received deceased donor grafts, and 7 (24.1&#x0025;) developed&#62; 1 acute rejection episodes. Pathologically, 7 (24.1&#x0025;) and 4 (13.8&#x0025;) patients had inflammation grade 3-4 and fibrosis stage 3-4, respectively. Follow-up biopsy in 9 (31&#x0025;) HCV genotype 4 patients showed stable, worse and improved fibrosis stage in 5, 2 and 2 patients, respectively. Of the 7 patients in the recurrent HCV group who died, 6 were infected with genotype 4 and 4 of them died of HCV-related disease. <b> Conclusion: </b> This analysis suggests that HCV recurrence following OLT in HCV-4 patients is not significantly different from its recurrence for other genotypes.
