Aim. - The study aimed to determine the effectiveness and tolerability of rosiglitazone, and its profile in terms of treatment adherence, treated patients and prescribing recommendations under everyday conditions of care. Methods. - This was a "real-life" observational longitudinal study including patients with type 2 diabetes mellitus (T2DM) starting treatment with rosiglitazone and followed for up to 2 years. A questionnaire was completed at the time of inclusion and during routine consultations at around 6, 12, 18 and 24 months following inclusion. Information was collected on sociodemographics, clinical history, treatments, co-morbidities, laboratory data and compliance with treatment. There were three primary outcome measures: treatment response (defined as an HbA(1c) <= 8.0% or a decrease in HbA(1c) >= 0.7%); switch to insulin (as considered necessary by the physician); and occurrence of adverse events requiring a change or discontinuation of treatment. Results. - The evaluation included 670 patients (61.1%) treated with rosiglitazone/metformin as fixed-dose combination tablets and 427 (38.9%) with standard rosiglitazone tablets. Rates of HbA(1c) response, defined as an HbA(1c) less than or equal to 8.0% or a decrease in HbA(1c) greater than or equal to 0.7%, ranged from 80.6% to 92.1% depending on the follow-up time. The percentage of patients with an HbA(1c) less than 7% was 18.4% before rosiglitazone was prescribed, and ranged from 48.2% to 57.8% depending on the follow-up period. Sixty-two patients (6.1%, 95% CI: 4.6-7.6%) switched to insulin therapy during the follow-up period. Spontaneously reported adverse events leading to a change or discontinuation of treatment were seen in 45 patients (4.4%, 95% CI: 3.2-5.6%). Conclusion. - Rosiglitazone showed sustained efficacy, with around 90% of patients defined as responders to the treatment in terms of reduction in HbA(1c), and was relatively well tolerated. The adverse-event profile was consistent with the known effects of rosiglitazone, and no signs of increased cardiovascular ischaemic risk were observed. These results are in agreement with previous studies on rosiglitazone.
