IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Objective To compare the efficacy and safety of anti-TNF-alpha treatment in RA patients with and without anti-Ro antibodies, in order to detect any change in their immunological or clinical profile. Methods Autoantibodies in 322 patients being treated with anti-TNF-a drugs were studied; 17 were found to be anti-Ro positive, while 305 were anti-Ro negative. Results Two groups, comparable in terms of sex distribution, RA duration and anti-TNF-alpha drug employed, showed symmetrical, erosive polyarticular RA with high disease activity. Anti-TNF-alpha led to significant improvement in both groups. At baseline rheumatoid factor and ANA, globally positive in 68.6% and 40%, were more frequent in anti-Ro positive sera. ANA showed a rising trend beginning in the 6th month of treatment in both groups, which was always statistically significant compared to baseline. Anti-dsDNA antibodies, measured using either CLIFT and ELISA or the Farr assay, remained stable in the first 6 months, then increased at 12th and 18th month, and subsequently declined. No difference was detected between the two groups regarding the number or cause of dropouts, but lupus-like disease was more frequent in anti-Ro positive subjects (p = 0.012). In addition, two cases of NHL were detected. Conclusion Anti-TNF-alpha treatment was shown to be effective inpatients with anti-Ro antibodies. Although anti-dsDNA and lupus-like disease were more frequent in anti-Ro positive patients, severe manifestations of systemic involvement were not observed. A longer follow-up is warranted to evaluate the risk of NHL in these patients.
