| pubmed-article:18080224 | pubmed:abstractText | In some steroid refractory patients with active ulcerative colitis (UC), treatment with immunosuppressive agents, such as cyclosporin, azathioprine or 6-mercaptopurin is effective. However, there are patients who fail to respond to these treatment options or who cannot tolerate them. Application of natural interferon-beta (nIFN-beta) may offer an alternative. Following our positive results with nIFN-beta in a previously published open-labeled study, the present study was designed as an extension with the hypothesis that administration of higher dosage of nIFN-beta (1.0 vs. 0.5 MIU) could result in fewer relapse events. | lld:pubmed |
