BACKGROUND Skin side effects during interferon-alpha and ribavirin treatment are common, but autoimmune dermatosis triggered by interferon-alpha is rare. We describe a case of erythrodermia from exacerbated psoriasis during the treatment of acute hepatitis C with pegylated-interferon-alpha and ribavirin. The incidence of psoriasis in this circumstance is unknown and only 36 cases are described ...

Enormous progress has been made in the understanding of the hepatitis C virus and the development of novel therapeutic agents since the identification of the virus, from initial interferon monotherapy to PEGylated interferon in combination with ribavirin for 48-72 weeks that used to be the standard of care in hepatitis C virus therapy. However, this combination has limited efficacy and a signif...

Chronic hepatitis B virus (HBV) is a serious and life-threatening disease afflicting 350 million of the world's population. So far, current monotherapy with conventional interferon-alpha, lamivudine, and adefovir dipivoxil remains unsatisfactory. In addition, the use of conventional interferon-alpha needs to be administered subcutaneously daily or thrice weekly and is associated with frequent a...

Attachment of poly(ethylene glycol) to proteins can mask immune epitopes to increase serum half-life, reduce immunogenicity, and enhance in vivo biological efficacy. However, PEGylation mediated epitope-masking may also limit sensitivity and accuracy of traditional ELISA. We previously described an anti-PEG-based sandwich ELISA for universal assay of PEGylated molecules. Here, we compared the q...

BACKGROUND/AIM In the treatment of hepatitis C, the National Institute for Clinical Excellence advocates use of a combination of interferon alfa and ribavirin for selected patients. Retinopathy is a well recognised side effect of interferon therapy and is characterised by retinal haemorrhages, cotton wool spots, and macular oedema. The aim of this study was to document the incidence and natural...

Hepatitis C is one of the leading causes of liver disease in the United States, affecting more than 4 million individuals. The current treatment regimen involves pegylated interferon in combination with ribavirin. Although antiviral treatment has been associated with a greater than 50% sustained viral response rate, the adverse effects have proven to be detrimental to quality of life and therap...

Interferon is used to treat hepatitis C virus infection and its cutaneous side effects are well known. Recently, interferon-induced sarcoidosis has been reported. We report a new case of sarcoidosis during pegylated interferon alfa and ribavirin treatment with an unusual presentation in a woman with previous episodes of erythema nodusum and nodular vasculitis related to HCV.

BACKGROUND Individuals with recent HCV infection may benefit from shortened duration therapy. These studies evaluated the efficacy and safety of response-guided regimens with pegylated interferon-α2a and ribavirin for people with recent HCV infection. METHODS Participants with recent hepatitis C (duration of infection ≤18 months) enrolled in the ATAHC II (pegylated interferon-α2a ± ribavirin)...

Hepatitis C virus (HCV) infection is an important public health issue worldwide. It is estimated that over 170 million people are infected with the virus. The present study reports six cases in which patients did not respond to combination therapy with pegylated interferon and ribavirin. However, after the addition of thalidomide to the therapy, the patients presented negative RNA PCR. The use ...

PURPOSE Recent clinical trials have evaluated treatment strategies for chronic infection with hepatitis C virus (HCV) in patients co-infected with human immunodeficiency virus (HIV). Our objective was to use these data to examine the cost-effectiveness of treating HCV in an urban cohort of co-infected patients. METHODS A computer-based model, together with available published data, was used t...
