During clinical activity, monocytes activation markers such as Interleukin 1 and tumor necrosis factor-alpha (TNF-alpha) increase. The effect of interferon beta (IFN-beta) in reducing exacerbation rate and in slowing sustained worsening of disability has been shown in MS. The aim of this study was to determine levels of monocytes percentage in peripheral blood of MS patients receiving IFN-beta. We carried out this study in two groups of MS patients and a group of healthy subjects. First (study) group consisted of 13 patients treated by INF-beta. The control groups consisted of a) 14 MS patients group with no treatment by INF- beta and b) 20 healthy subjects. We counted the percentage of monocytes in the study group before and after one year of treatment by IFN- beta and in the control groups patients in the same period. At the end of one year, there was a significant reduction in the percentage of monocytes in peripheral blood of MS patients treated by interferon.eninfo:eu-repo/semantics/openAccessMultiple SclerosisInterferon TherapyMonocytesPeripheral BloodArticle322N/AN/A7781WOS:000182492100001
