Insights
Hepatitis C virus (HCV) genotype 1b is more common in liver transplant patients, particularly older individuals with hepatocellular carcinoma. This finding highlights genotype 1b
Area of Science:
- Hepatology
- Virology
- Transplant Surgery
Background:
- Hepatitis C virus (HCV) genotype 1b is prevalent in Spain and associated with poorer prognosis.
- Understanding genotype distribution is crucial for managing HCV infection, especially in liver transplant recipients.
Purpose of the Study:
- To compare HCV genotype distribution in a liver transplant unit with the general HCV patient population.
- To determine if genotype 1b is more prevalent in patients with severe liver disease, including those undergoing liver transplantation.
Main Methods:
- Analysis of 108 patients (81 liver transplant recipients, 27 with HCV cirrhosis) and a control group of 413 HCV patients.
- HCV genotyping performed using the Inno-LiPA HCV III assay.
Main Results:
- Genotype 1b was highly prevalent (86.1%) in the liver transplant unit, significantly higher than in the control group (69.5%, P < .001).
- Genotype 1b patients were older and more frequently had hepatocellular carcinoma (78.6% of cases).
- Genotype distribution was similar between liver transplant recipients and patients with cirrhosis.
Conclusions:
- Genotype 1b is the predominant HCV genotype in liver transplant recipients.
- The higher prevalence of genotype 1b in this group may be linked to older age and increased rates of cirrhosis and hepatocellular carcinoma.
Introduction:
Among the at least six major identified genotypes of HCV, genotype 1b, the one associated with a poorer prognosis, is the most prevalent in Spain. We aimed to compare the distribution of hepatitis C virus genotypes in our liver transplant unit with that of the other HCV patients at our institution (n = 413) in order to assess whether genotype 1b is more prevalent among patients with more severe liver disease.
Patients And Methods:
One hundred eight patients of mean age 56 years included 81 (75%) OLT recipients and 27 (25%) with HCV cirrhosis. Determination of HCV genotypes was made with the Inno-LiPA HCV III.
Results:
The overall distribution of genotypes was: 1b, 93 patients (86.1%); 1a; eight patients (7.4%); 3, four patients (3.7%); 4; two patients (1.9%), and 2; one patient (0.9%). The distribution was similar among patients with cirrhosis and OLT. Genotype 1b patients were older. Eleven (78.6%) of 14 patients with hepatocellular carcinoma had genotype 1b. In the control group the distribution was: 1b, 287 patients (69.5%); 1a, 54 patients (12.1%); 3, 41 patients (9.9%); 4, 20 patients (4.8%), and genotype 2, 11 patients (2.7%). This differences in the distribution of genotypes between our population and the control group was statistically significant (P < .001).
Conclusions:
Genotype 1b, the most prevalent genotype in our liver transplant unit, included older patients in whom hepatocellular carcinoma was common, perhaps due to their higher prevalence of cirrhosis.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
