OBJECTIVE.

To analyze the experience in daily clinical practice of interferon beta (IFN-b) treatment in relapsing-remitting (RR) and secondary progressive (SP) multiple sclerosis (MS) in Galicia (Spain).

PATIENTS AND METHODS.

Patients with RR-MS and SP-MS treated with IFN-b 1a and 1b between 1995 and December/2000, analyzing demographic and clinical data.

RESULTS.

313 patients were included, with a mean age of 38,2 years.

A total of 296 patients (94,6%) were clinically defined MS and 17 (5,4%) were laboratory supported (Poser criteria); 84,6% of the patients were RR and 15,4% were SP.

The mean duration of the disease prior to treatment was 7,06 years.

Betaferon a was used in 52,4% patients (115 RR-MS and 47 SP-MS), Avonex a in 26% and Rebif a in 21,6%.

Relapse rate was reduced in 68,8% for the RR-MS for Betaferon-treated patients, 73,3% for Avonex treated and 35,7% for Rebif-treated patients.

Betaferon reduced relapse rate in 50% for SP-MS.

The global EDSS remained stable during IFN-b treatment.

During treatment, 33% of Betaferon, 60,5% of Avonex and 54,5% of Rebif-treated patients remained relapse-free.

Treatment was suspended in 12,9% of Betaferon, 6,2% of Avonex, and 3% Rebif-treated patients.

The most frequent causes of treatment suspension were increase in disability and in relapse count.

CONCLUSIONS.

The present study supports the benefits of IFN-b treatment in RR MS and SP MS in daily clinical practice, with reduction in relapses count and discapacity, good over-all tolerance and low incidence of serious adverse side-effects.
