OBJECTIVES To investigate the heterogeneity in magnetic resonance image (MRI) patterns of response to interferon beta across patients with multiple sclerosis or within an individual patient over time. DESIGN, SETTING, AND PATIENTS Fifteen patients with relapsing-remitting multiple sclerosis underwent monthly MRIs and clinical examinations (6-month pretherapy phase and 36-month therapy phase) ...

To improve the efficacy of interferon (IFN) treatment for chronic hepatitis C, we have proposed the twice-daily administration of IFN-beta as a promising induction therapy. In this study, we demonstrated differences between the clearance of circulating HCV-RNA and the induction of anti-viral actions during the first 2 weeks of treatment. Nine patients with a high viral load and genotype 1b were...

INTRODUCTION Although it has been shown that immunomodulatory therapies (IMTs) in multiple sclerosis (MS) can modify the course of the disease by reducing the relapse rate and delaying the progression of disability, no study comparing IMTs head-to-head in terms of clinical, radiological, and electrophysiological changes is available. We aimed to investigate the effects of interferon-beta (IFN-B...

AIM To investigate the mechanism by which hepatitis C virus (HCV) core protein-induced miR-93-5p up-regulation regulates the interferon (IFN) signaling pathway. METHODS HCV-1b core protein was exogenously expressed in Huh7 cells using pcDNA3.1 (+) vector. The expression of miR-93-5p and interferon receptor 1 (IFNAR1) was measured using quantitative reverse transcription-polymerase chain react...

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...

HCV (hepatitis C virus) research, including therapeutics and vaccine development, has been hampered by the lack of suitable tissue culture models. Development of cell culture systems for the growth of the most drug-resistant HCV genotype (1b) as well as natural isolates has remained a challenge. Transfection of cultured cells with adenovirus-associated RNA(I) (VA RNA(I)), a known interferon (IF...

BACKGROUND Interferon beta 1b (Betaferon) and 1a (Avonex) were licensed in Italy for treating relapsing-remitting multiple sclerosis in February 1996 and August 1997, respectively. OBJECTIVES To evaluate the effectiveness of these agents on the basis of clinical experience in northern Italian multiple sclerosis centres. DESIGN Clinical data on patients with relapsing-remitting multiple scle...

BACKGROUND The spectrum of side effects related to interferon beta-1b (INF-1b) treatment may compromise long-term adherence. METHODS Five INF-1b-treated multiple sclerosis patients with poor skin tolerability and clinical stability were instructed to dissolve the established (250 μg) INF-1b dose in half (0.5 mL) the standard diluent (1.0 mL, 0.54% sodium chloride solution), and were followed ...

Multiple sclerosis (MS) is the most common autoimmune illness of the central nervous system. For many years the inflammatory manifestations of MS were treated using only corticosteroids. Since the 1990s the results of several clinical trials with immunomodulatory agents have changed the therapeutic approach to this disease. Interferon beta (IFNbeta)-1b represents the pioneer of those therapies....

OBJECTIVES Previous systematic reviews and meta-analyses of treatments in relapsing-remitting multiple sclerosis (RRMS) derived their findings from either placebo-controlled studies only or separately from head-to-head and comparative studies. The purpose of this study is to compare annualized relapse rates (ARR) of fingolimod versus all of the commonly used first-line treatments in RRMS using ...
