Skin diseases associated with hepatitis C virus infection
1Academic Department of Medicine, Hippokration General Hospital, Athens, Greece.
Insights
Hepatitis C virus (HCV) infection frequently causes liver disease and affects non-hepatic tissues, notably skin. Various dermatological conditions are linked to HCV, but treatment responses vary.
Area of Science:
- Hepatology
- Dermatology
- Virology
Background:
- Hepatitis C virus (HCV) is a global cause of liver disease, transmitted parenterally.
- HCV infection impacts both hepatic and extrahepatic tissues, with significant dermatological involvement.
- Numerous skin disorders are associated with HCV, requiring further etiological investigation.
Purpose of the Study:
- To review the association between Hepatitis C virus infection and various dermatological conditions.
- To highlight the spectrum of skin manifestations linked to HCV.
- To discuss the implications for patient management and treatment response.
Main Methods:
- Literature review of studies investigating HCV and extrahepatic manifestations.
- Analysis of recognized dermatological diseases associated with HCV.
- Examination of treatment outcomes, particularly with interferon alpha therapy.
Main Results:
- Key skin diseases frequently associated with HCV include cutaneous necrotising vasculitis, mixed cryoglobulinemia, porphyria cutanea tarda, and lichen planus.
- Other potential HCV-associated skin disorders include Adamantiadis-Behçet syndrome, erythema multiforme, and urticaria.
- Skin manifestations can also be part of other HCV-related extrahepatic disorders like thyroid dysfunction and thrombocytopenia.
Conclusions:
- Hepatitis C virus infection has a significant association with a wide range of dermatological diseases.
- The precise etiological role of HCV in some skin conditions requires further research.
- Treatment responses to interferon alpha for HCV-related skin diseases are variable and unpredictable.
Abstract:
Hepatitis C virus (HCV) is a bloodborne agent transmitted by apparent and inapparent parenteral procedures representing a frequent cause of liver disease world-wide. Both acute and chronic HCV infection may affect the liver as well as various non-hepatic tissues. Numerous extrahepatic disorders have been recognised in association with HCV infection among which dermatological diseases occupy a central part. Cutaneous necrotising vasculitis, mixed cryoglobulinemia, porphyria cutanea tarda and lichen planus are the major skin diseases frequently associated with HCV infection, but other skin disorders, such as Adamantiadis-Behçet syndrome, erythema multiforme and nodosum, malacoplakia, urticaria and pruritus, may also be linked to hepatitis C. Further studies are necessary to establish or refute an aetiopathogenetic role of HCV in these conditions. Skin manifestations are also part of the clinical picture of other extrahepatic disorders associated with HCV infection, such as thyroid dysfunction and HCV-related thrombocytopenia. The response to interferon alpha (alpha-IFN) therapy in skin diseases is unpredictable with some patients ameliorating, others remaining stationary and others deteriorating.
