To verify the possible effect of IFN-β treatment on auto antibodies development in multiple sclerosis (MS) we studied 69 MS patients before and during the treatment with IFN-β 1b (n = 35) and IFN-β 1a (n = 20) for 27 and 12 months respectively, and, as controls, 14 untreated MS patients. The serum, collected every 3 months from all the patients, was investigated for the presence of antinuclear (ANA), anti-smooth muscle (ASMA), anti-mitochondrial (AMA), anti-native DNA (nDNA) anti-cardiolipin (aCL), anti-parietal cells (APCA), anti-microsomal (AMC) and anti-tireoglobulin (ATG) antibodies. Among the IFN-β 1b-treated MS patients an increase of the frequency and of the level of ANA, AMC and ATG was observed. ASMA and ANA antibodies were already present in about 45% of the MS patients before the treatment and fluctuated over the time. In one patient the treatment was interrupted after 6 months because of the occurrence of high ASMA level and of an autoimmune hepatitis. The data obtained in the smaller number of MS patients treated with IFN-β 1a were very similar. No increase in aCL level was observed during both the IFN treatments. Our results indicate that the treatment with IFN-β induces an increase of AMC and ATG antibodies in MS patients and confirm that, although rare, autoimmune diseases could be observed. The possible effect of these auto antibodies on the treatment efficacy and on MS clinical course need to be further investigated.
