Isolated cases of pulmonary arterial hypertension (PAH) in patients treated with interferon (IFN) α or β have been reported in the literature. The aim of this study was to describe all consecutive cases of PAH patients with a history of IFN exposure identified in the French reference centre for severe pulmonary hypertension between 1998 and 2012. A total of 53 patients with PAH and a history of...

aim : to evaluate the effect of active t. gondii tachyzoites and its products on the gene expression level of ifn-yr1 and ifn-yr2 in a murine model.   background : many studies have shown that the parasite toxoplasma gondii utilizes different mechanisms to inhibit the function of ifn-?, but the parasite effect on the function of ifn-yr1 and ifn-yr2 is still unclear. patients and methods : toxop...

Background: This study was performed to compare the effects of low dose interferon beta-1 (IFN-β-1) (CinnoVex, 30 mcg) and high dose IFN-β-1 (REBIF, 44 mcg) on the reduction of the number and size of plaques in magnetic resonance imaging (MRI) in patients with multiple sclerosis (MS). Methods: This historical cohort study, which was performed in 2014 in Sanandaj (western part of Iran). 43 MS pa...

Adult T-cell leukemia/lymphoma ATL is an aggressive T cells malignancy, with poor prognosis due to chemotherapy resistance. Preliminary results using zidovudine (AZT) and interferon-alpha (IFN) showed high response rate in ATL patients. We report a prospective phase II trial using AZT/IFN treatment for aggressive ATL. Nineteen ATL patients (15 acute and four lymphoma) were included in this stud...

Interferon-alpha (IFN) is widely used in the treatment of certain cancers and viral infections, including hepatitis C (HCV). Unfortunately, depression is a common side effect of IFN therapy, affecting approximately a third of HCV patients receiving IFN therapy. Studies have shown that selective serotonin reuptake inhibitors (SSRIs) can effectively treat IFN-induced depression in only 63-75% of ...

UNLABELLED For the past 40 years, various forms of interferon (IFN) have been evaluated as therapy in a number of malignant and non-malignant diseases. With the advent of gene cloning, large quantities of pure IFN became available for clinical study. This paper reviews the biology, pharmacology, and clinical applications of IFN formulations most commonly used in oncology. It then reviews the mo...

Homoharringtonine (HHT) is a novel plant alkaloid that produced a complete hematologic remission (CHR) in 72% of patients with late chronic phase chronic myelogenous leukemia (CML). Cytogenetic (CG) remissions were noted in 31%. In this study, six courses of HHT were administered to 90 patients with early chronic phase CML (< 1 year from diagnosis). Patients then received interferon-alpha (IFN-...

Viral infection is a significant burden to health care worldwide. Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors, are widely used as cholesterol-lowering drugs. Recently, long-term statin therapy was shown reduce the antiviral immune response; however, underlying molecular mechanisms unclear. Here, we found that simvastatin decreased polyinosinic–polycytidylic acid [poly(I...

Chronic hepatitis C virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma. Combination therapy of pegylated interferon-alpha (PEG-IFN-α) and ribavirin (RBV) is a current standard treatment for chronic HCV infection in Korea, which has considerable adverse effects. Acute pancreatitis is a rare complication of PEG-IFN-α administration. We report a case of a 62-yea...

The vesicular stomatitis virus cytopathic effect reduction assay is suitable to quantify polyethylene glycol-alpha interferon 2a (PEG-IFN-alpha 2a) and PEG-IFN-alpha 2b. Human serum and ribavirin did not interfere with the assay. This bioassay was successfully used for assaying PEG-IFN-alpha 2a and PEG-IFN-alpha 2b in serum samples from patients undergoing combination therapy.
