Tacrolimus is a calcineurin inhibitor which works to induce immune suppression by preventing cytokine transcription and lymphocyte activation. Combining the immunomodulator interferon beta-1b (Betaseron) with the immunosuppressant tacrolimus (Prograf) may have the potential of additive therapeutic benefit through the complementary mechanisms of action of these two therapeutics. In this randomiz...

BACKGROUND The EVIDENCE (Evidence of Interferon Dose-Response: European North American Comparative Efficacy) Study demonstrated that patients with multiple sclerosis (MS) who initiate interferon beta-1a therapy with 44 microg 3 times weekly (TIW) were less likely to have a relapse or activity on magnetic resonance imaging (MRI) compared with those who initiate therapy at a dosage of 30 microg 1...

The aim of the study was to analyze the usefulness and side effects of treatment with interferon beta 1B (Betaferon) in patients with the relapsing-remitting form of multiple sclerosis (RRMS). The study included 32 RRMS patients that had completed two-year therapy with interferon beta 1B or were still receiving this therapy. Every six months, patients were clinically evaluated and scored by the...

We have previously identified a 15-kDa interferon-induced protein that is recognized by affinity-purified rabbit polyclonal antibodies against ubiquitin (Haas, A. L., Ahrens, P., Bright, P. M., and Ankel, H. (1987) J. Biol. Chem. 262, 11315-11323). This ubiquitin cross-reactive protein (UCRP) possesses significant homology to a tandem diubiquitin sequence. Since the biological effects of ubiqui...

Interferons have been shown to lower low density lipoprotein (LDL) cholesterol concentrations by 20-50%. To evaluate the effect of interferons on LDL metabolic behavior in individuals with normal and mildly elevated LDL cholesterol levels, autologous LDL labeled with 125I was administered to subjects at baseline and during interferon treatment. Interferon beta serine (IFN-beta serine) was admin...

OBJECTIVE To determine relevant HLA-DRB1 alleles associated with the susceptibility of anti-interferon beta antibody development in a large patient cohort. DESIGN In a case-control study, HLA-DRB1 genotyping was performed in a discovery cohort (n = 268) and a validation cohort (n = 825). SETTING Patients were recruited in Germany by primary care physicians and neurologists and were mainly o...

In a study aimed at correlating cytokine levels in synovial fluid with the pathology of rheumatoid arthritis (RA), tumour necrosis factor alpha, interleukin 1 beta and interferon gamma were immunoassayed in 27 patients with RA, 16 patients with other arthritides, 23 with osteoarthritis, 13 patients with trauma, and 18 patients at necropsy without inflammatory disease and not known to have had j...
