Insights
Most patients with chronic hepatitis C (CHC) in Poland experience extrahepatic manifestations (EM). Lower platelet count is a key predictor of these CHC-associated conditions.
Area of Science:
- Hepatology
- Immunology
- Internal Medicine
Background:
- Chronic hepatitis C (CHC) is a significant global health concern.
- Extrahepatic manifestations (EM) are common complications of CHC, impacting various organ systems.
- Understanding the prevalence and predictors of EM in CHC is crucial for patient management.
Purpose of the Study:
- To determine the frequency of extrahepatic manifestations (EM) in Polish patients with chronic hepatitis C (CHC).
- To identify factors that predict the occurrence of EM in this patient cohort.
Main Methods:
- A study of 340 treatment-naïve CHC patients in Poland (2000-2006).
- HCV infection confirmed by serology and RNA.
- Assessment of liver inflammation and fibrosis using Ishak scoring.
- Exclusion of patients with cirrhosis, co-infections (HBV, HIV), autoimmune liver disease, or alcohol abuse.
Main Results:
- Over 60% of CHC patients (61.7%) exhibited at least one EM.
- Common EM included cryoglobulinemia (37.1%), thrombocytopenia (27.6%), thyroid autoimmunity (16.2%), and type 2 diabetes (4.1%).
- Multivariate analysis identified a lower platelet count as a significant predictor of EM in CHC patients.
Conclusions:
- A high prevalence of EM is observed in Polish CHC patients.
- Cryoglobulinemia, thrombocytopenia, thyroid autoimmunity, dermatological disorders, and type 2 diabetes are the most frequent EM.
- Lower platelet count is a predictive factor for EM in chronic hepatitis C.
Purpose:
To assess the prevalence and predictive factors of extrahepatic manifestation (EM) in patients with chronic hepatitis C (CHC) infection in Poland.
Material And Methods:
340 consecutive patients (mean age: 42 years) with untreated CHC were studied between 2000 and 2006. The HCV infection was defined by positive serology and serum HCV RNA. The inflammation grade and fibrosis stage were assessed according to Ishak. Demographic, laboratory and liver biopsy data were collected. The patients with liver cirrhosis, concomitant HBV or HIV infection, autoimmune liver diseases and alcohol abusers were excluded from the analysis.
Results:
210 patients with CHC (61.7%) presented at least 1 extrahepatic manifestation, including mixed cryoglobulinemia (37.1%), thrombocytopenia (27.6%), thyroid autoimmunity (16.2%), dermatological disorders (4.1%) and type 2 diabetes (4.1%). Other EM such as the sicca syndrome, nephropathy, polyneuropathy and B-cell lymphoma were observed in single cases. In multivariate analysis lower platelet count was found as a predictive factor of EM in patients with CHC.
Conclusions:
The majority of patients with CHC, living in Poland, have EM, of which cryoglobulinemia, thrombocytopenia, thyroid autoimmunity, dermatological disorders and type 2 diabetes are most common. Through the multivariate analysis the lower platelet predicts extrahepatic manifestations associated with chronic hepatitis C.
