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...

background: brucella is a gram-negative bacterium, causing acute and chronic infection in humans and animals. cell-mediated immunity is the main protective immune response against brucella spp. activation of macrophages by ifn-γ and generation of reactive oxygen intermediates and nitric oxide are the main immunologic mechanisms responsible for control of brucella infection. objective: to invest...

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...

BACKGROUND/AIMS Hepatitis C virus infection remains prevalent among patients undergoing long-term haemodialysis and has a detrimental impact on survival in this population. Antiviral therapy for chronic hepatitis C in haemodialysis patients is still a challenge to clinicians. The aim of the current study is to evaluate the efficacy and safety of therapy with pegylated interferon, alone or combi...

bronchiolitis has been known as one of the pathological features of lung injuries in mustard gas exposed patients the purpose of this research was to evaluate the efficacy of interferon gamma-1b on the lung function in mustard gas exposed patients with bronchiolitis. in multicenter research interferon gamma-1b was effective in pulmonary fibrosis with unknown reason, but assessment of effect of ...

BACKGROUND/AIMS We aimed to compare viral responses to pegylated interferon 2a plus ribavirin with pegylated interferon alpha 2b plus ribavirin. METHODS Patients with the following characteristics were included: anti HCV(+); normal and/or elevated serum transaminase levels; positive HCV RNA by quantitative PCR; and at least stage 1 fibrosis according to Knodell Scoring System on liver biopsy....

BACKGROUND Hepatitis C virus (HCV) infection is a global public health issue. Adequate treatment for hepatitis C patients is important, but anticipated side effects make patients fearful of receiving treatment. Little is known about the experiences of hepatitis C patients who have completed treatment with pegylated interferon and ribavirin. The purpose of this study was to explore the experienc...

The effect of interferon alfa against hepatitis C virus has been well documented. However, clinical efficacy is low due to the short interferon residence in the body. To prolong half-life, interferon molecules have been bound to the biologically inert polymer, polyethyleneglycol. Pegylated interferons exhibit a longer residence time with an improved clinical efficacy, although the rate of thera...

There are seven approved treatments for adults with chronic hepatitis B virus infection in the United States and European countries: interferon-α, pegylated interferon-α, lamivudine, adefovir dipivoxil, entecavir, telbivudine, and tenofovir disoproxil fumarate. At present, two new analogues, entecavir and tenofovir are recommended as the first line therapy by the guidelines of European Associat...
