Insights
Hepatitis C virus (HCV) infection is more prevalent in psoriasis patients than in the general population. Patients with psoriasis and HCV exhibited more severe skin lesions, indicating a significant association.
Area of Science:
- Hepatology
- Dermatology
- Infectious Diseases
Context:
- Hepatitis C virus (HCV) is a significant global health concern, linked to liver disease and extrahepatic manifestations.
- Psoriasis, a chronic inflammatory skin condition, has been anecdotally associated with HCV, but requires further investigation.
- Understanding this comorbidity is crucial for comprehensive patient management and public health strategies.
Purpose:
- To determine the prevalence of anti-HCV antibodies (confirmed by HCV-RNA) in patients with psoriasis.
- To assess the clinical implications of HCV infection in this cohort, including skin lesion severity and liver disease.
- To investigate the co-occurrence of other viral infections, such as hepatitis B virus (HBV), HTLV-I/II, and HIV I/II, in psoriasis patients.
Summary:
- A cross-sectional study in Salvador, Bahia, analyzed 140 psoriasis patients aged over 18.
- Serological tests revealed a 7.1% anti-HCV prevalence, significantly higher than the city's general population (1.5%).
- HCV-positive patients presented with higher Psoriasis Area and Severity Index (PASI) scores and advanced liver fibrosis (METAVIR F3/F4).
Impact:
- The findings highlight a higher prevalence of Hepatitis C virus in psoriasis patients, suggesting a need for routine HCV screening in this population.
- The association between HCV and more severe psoriasis indicates potential shared pathophysiological mechanisms or exacerbation of skin disease by viral infection.
- This study underscores the importance of considering viral infections in the comprehensive care of patients with chronic inflammatory conditions like psoriasis.
Introduction:
Hepatitis C is the major cause of liver transplantation and hepatocellular carcinoma and shows a global prevalence of 3%. Hepatitis C virus (HCV) is associated with extrahepatic manifestations (e.g., cutaneous affections) and psoriasis has been reported as a comorbidity. However, there are few studies analyzing this association.
Objectives:
1) To evaluate anti-HCV prevalence (confirmed by the detection of HCV-RNA) in patients with psoriasis and its potential clinical implications; 2) to analyze the prevalence of other infections in this population: hepatitis B virus (HBV), human T lymphotropic virus, subtypes I and II (HTLVI/II), and human immunodeficiency virus, subtypes I and II (HIV I/II).
Methods:
This is cross sectional study that included patients older than 18 years-old with psoriasis from a Teaching Hospital in Salvador, Bahia. An epidemiological questionnaire was administered and serological tests were performed: surface HBV antigen (HBsAg), antibodies to HBsAg (anti-HBs), anti-HTL VI/II, anti-HIV I/II, and anti-HCV. Anti-HCV positive results were confirmed by HCV-RNA detection and viral genotype was determined. Skin lesions were evaluated using the Psoriasis Area and Severity Index (PASI). Liver biopsies were analyzed according to the METAVIR score.
Results:
From the 140 patients included in the study, 7.1% were anti-HCV positive confirmed by the detection of HCV RNA. This prevalence was higher than that in the city of Salvador (1.5%). Other serological results were: HBsAg 0%, anti-HBs 25.8%, HTLV I/II (0,9%), and HIV I/II 0%. PASI score was higher in positive anti-HCV patients than in their negative counterparts (19.5 versus 13.4). Histopathological analysis showed 66.7% of patients with METAVIR F3/F4.
Conclusion:
Anti-HCV prevalence was higher in psoriasis patients than in the general population of the city. More severe skin lesions were found in HCV patients.
