The Philadelphia negative myeloproliferative neoplasms, including polycythemia vera, essential thrombocythemia, and myelofibrosis, are associated with substantial vascular and transformative complications. Standard therapy for high-risk disease, particularly in patients that have failed initial therapy, remains controversial. Non-pegylated interferon has previously been shown to be effective in...

Cardiac arrhythmias and syncope are rare consequence of therapy with pegylated interferon. We report a 55-year-old Egyptian woman who developed palpitation and syncopal attacks twice within 3 months after starting therapy with pegylated interferon alpha2b and ribavirin for the treatment of chronic hepatitis C virus. Hepatitis C virus-RNA was undetectable after 12 week. The electrocardiogram hol...

Autoimmune manifestations are common both in patients chronically infected by hepatitis C virus, and in patients transplanted for non-autoimmune diseases. A correlation between interferon based treatment and autoimmune diseases or the development of autoantibodies is well established in non-transplanted patients, but few data are available about transplanted patients. It is unclear whether inte...

conclusions more than one-quarter of treatment-experienced patients with hcv genotype 3 achieved svr after re-treatment with consensus interferon plus ribavirin. objectives we aimed to assess the efficacy and safety of cifn and ribavirin in non-responders and relapsers to pegylated interferon with ribavirin therapy. patients and methods this open-label investigator-initiated study included 44 p...

hepatitis c virus (hcv) has chronically infected million peoples worldwide. spontaneous viral clearance occurs in 25% of affected patients.  the standard regimen to treat hcv infection is the combination of pegylated interferon and ribavirin.

We have previously described the safety and efficacy of pegylated interferon-α2a therapy in a cohort of 62 patients with myeloproliferative neoplasm-associated myelofibrosis followed in centers affiliated to the French Intergroup of Myeloproliferative neoplasms. In this study, we report their long-term outcomes and correlations with mutational patterns of driver and non-driver mutations analyze...

Pegylated interferon remains the first line treatment for patients with hepatitis D virus and more than one year therapy may be necessary. Interferon a has the most extensive clinical application and is used for the treatment of chronic hepatitis B and D virus as well as HCV infections. The attachment of polyethylene glycol to interferon increases its half-life. Treatment with peg interferon is...

a 46-year-old woman presented with progressive dyspnea and cough. she was a known case of chronic hepatitis c (hcv) treated with pegylated (peg)-interferon. complete pulmonary studies and biopsy were compatible with bronchiolitis oblitrans with organizing pneumonia (boop) secondary to peg-interferon. she discontinued peg-interferon and was given a short course of steroids, after which the condi...

Hepatitis flare is rarely observed during treatment with pegylated interferon alpha for hepatitis C virus (HCV) infection. A 49-year-old man receiving pegylated interferon α-2a for HCV infection had icterus and hyperbiliru-binemia in the 14th week of therapy, with HCV RNA undetectable after the 12th dose. Liver biopsy was suggestive of chronic hepatitis with cirrhosis without interface pattern....

Nanotechnology is the application of nanotechnology within medicine. An illustration of this is the use of pegylation as a means of modifying naturally occurring proteins which may have clinical applications, in order to improve the pharmacodynamics of the protein resulting in an effective medication. An example of this is pegylated interferon. The purpose of this review is to examine the chemi...
