- Relatively little research is available comparing the efficacy and tolerability of selective serotonin reuptake inhibitors (SSRIs) during continuation therapy. This investigation reports the differential effect of 6 months of treatment with sertraline versus paroxetine for symptoms of depression, quality of life, and personality outcomes. Outpatients with unipolar major depression (DSM-III-R) were randomly assigned to receive 24 weeks of double-blind treatment with flexible doses of paroxetine (20-40 mg) or sertraline (50-150 mg). Assessments included the Montgomery-Asberg Depression Rating Scale (MADRS), the Clinical Global Impression Scale, the Battelle Quality of Life Questionnaire, and the Structured Clinical Interview for DSM-III-R Personality Disorders screen questionnaire. One hundred seventy-six patients (mean age, 43 years, 64% female, baseline MADRS, 30.3) were treated with sertraline and 177 patients (mean age, 42 years, 71% female, MADRS, 30.7) with paroxetine. Antidepressant efficacy during continuation therapy was sustained, with only 2% of patients receiving sertraline and 9% of patients receiving paroxetine suffering a relapse. Continuation therapy resulted in a substantial conversion of responders during short-term treatment to full remission: remitter rates increased from 52% to 80% for sertraline and from 57% to 74% for paroxetine. The improvements in quality of life were related to a reduced depression score. SSRI treatment had significant beneficial effects on both categorical and dimensional measures of personality. A logistic regression analysis identified early response (25% reduction in MADRS scores at week 2) as the most important predictor of treatment response, whereas high severity, chronicity, and poor baseline quality of life had no effect. Both treatments were well-tolerated, with sertraline having a somewhat lower side effect profile. Sertraline and paroxetine demonstrated comparable efficacy during short-term and continuation therapy. Treatment was associated with significant improvement in quality of life and with reductions in axis II personality psychopathology.

- Medication non-adherence is a major obstacle in the treatment of affective disorders. The primary objective of this study was to evaluate two different interventions to improve adherence to antidepressant drugs. Secondary objectives included response to treatment, relation between adherence and response, patient satisfaction and tolerability. A randomized controlled design was used to assess the effect of a patient educational compliance enhancing programme (CP) and therapeutic drug monitoring in 1031 major depressed patients treated with sertraline for 24 weeks and managed by their general practitioner. Adherence was measured by questioning, measurable serum levels of sertraline and desmethylsertraline, appointments kept and a composite index including all three methods. Treatment adherence was found in 37-70% of patients, depending on the method used. Neither of the interventions resulted in a significant increase in adherence rate. However, significantly more patients in the CP group had responded at week 24 compared to patients in the control group. Overall, significantly more adherent patients responded to treatment compared to non-adherent patients, regardless of method used to determine adherence. This large study demonstrates that treatment response increases when using an educational compliance programme and that a strong relationship between treatment adherence and response exists. ⌐ 2003 Lippincott Williams & Wilkins.

- Non-adherence to antidepressant drug treatment is common. In a recent study in depressed primary care patients, we reported a strong relationship between adherence and response after 6 months. With the use of a naturalistic design, the patients in that study were prospectively followed for 2 years. The purpose of the present study was to investigate the patients' long-term outcome and, in particular, to examine the impact of patients' treatment adherence on response, remission and relapse. Of the 1031 patients in the intent-to-treat (ITT) sample, 835 completed the study. After 2 years, the overall remission rate defined as a Montgomery-Åsberg Depression Rating Scale score of nine or less was 68% in the ITT sample analysed with the last observation carried forward (LOCF) technique, and 75% in observed cases. In total, 34% of the responders experienced at least one relapse. Response rates (LOCF) were significantly higher in adherent compared to non-adherent patients at week 24 [95% confidence interval (CI) = 21.4-32.1], year 1 (95% CI = 12.3-22.2) and year 2 (95% CI = 9.2-19.0). Remission rates (LOCF) were also significantly higher in the group of adherent patients at week 24 (95% CI = 9.6-21.5), year 1 (95% CI = 10.0-21.5) and year 2 (95% CI = 11.0-22.0). No relationship between adherence and relapse rate was observed, although the mean time from response to first sign of relapse was significantly longer in the adherent patients (95% CI = 9-97 days). In conclusion, this 2-year follow-up study showed superior long-term recovery in patients who were adherent to antidepressant medication compared to non-adherent patients. © 2006 Lippincott Williams & Wilkins.
