Immunologic and antitumor effects of human recombinant interferon-gamma were studied in patients with renal cell carcinoma. A daily dose of 6 to 12 x 10(6) units/m2 of interferon-gamma was given by intravenous drip infusion or intramuscular injection to nine patients over a period varying from two to 16 weeks. Antibody-dependent cell-mediated cytotoxicity and OKIa1-positive monocytes count incr...

aim : the objective of this study was to estimate the average cost of diagnosis and treatment of hepatitis c among patients based on their treatment regime, during the one course of treatment and six-month after stopping that. background : hepatitis c virus (hcv) infection is a major cause of liver-related morbidity and mortality worldwide and a major public health problem. patients and methods...

OBJECTIVE: To describe the results of the use of alpha-2a-interferon in the treatment of inoperable childhood lymphangiomas refractory to other therapeutic management. METHOD: We reviewed the literature about pathogenic events and the treatments available for lymphangiomas. Based on that, we used alpha-2a-interferon at a dose of 3 million units/m(2)/day administered subcutaneously to patients w...

Three enzymes that cause inhibition of mRNA translation, eukaryotic initiation factor 2 protein kinase PK-i, oligoisoadenylate synthetase E, and phosphodiesterase 2'-PDi, have been recently isolated from interferon-treated cells. We show that the rise in these three enzyme activities may be used to study the response of uninfected cells to interferon. For each enzyme, a specific microassay that...

We report that human leukocyte interferon preparations increase the expression of beta 2-microglobulin by 100-200% on the surface of normal fibroblast and melanoma cell lines sensitive to interferon. This increase in expression can be correlated with an increase in HLA synthesis as measured by incorporation of [35S]methionine in these antigens. This enhanced HLA synthesis, which is 5- to 17-fol...

Fructose and glucose are often widely used in food processing may contribute to many metabolic diseases. To observe the effects of different doses fructose on human metabolism cellular communication, volunteers were given low, medium, high fructose. Serum cytokines, glucose, lactate, nicotinamide adenine dinucleotide (NADH) enzymes assayed, central carbon pathway networks cytokine communication...

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....

Treatment with interferon alfa combined with ribavirin is successful in approximately 40% to 45% of patients with chronic hepatitis C viral infection (HCV). However, response rates are disappointing in patients who are difficult to treat, such as those infected with HCV genotype 1, high viral load, or advanced liver fibrosis. In addition, low tolerability and significant side effects of therapy...

Eleven male patients with genital warts were given injections of fibroblast interferon (300 u) and placebo into the bases of two similar warts. The changes in size of the treated warts compared with that of the controls suggested that interferon did inhibit the growth of the warts. The dose given was probably insufficient for a dramatic effect. In one patient, however, a wart on the penile shaf...

Hematologic abnormalities such as anemia, neutropenia, and thrombocytopenia are common during combination therapy with pegylated (or standard) interferon and ribavirin for chronic hepatitis C. Ribavirin-induced hemolytic anemia is a common cause of dose reduction or discontinuation. Bone marrow suppression also contributes to the anemia and is the predominant mechanism for interferon-induced ne...
