The impact of clinical symptoms and endoscopic and histologic disease activity on health-related quality of life in patients with ulcerative colitis following treatment with multimatrix mesalazine.

PURPOSE: Studies of patients with ulcerative colitis (UC) report that reduced clinical symptoms and endoscopic activity predict better health-related quality of life (HRQoL). However, no study has examined the joint and unique associations of clinical and endoscopic activity with HRQoL, nor of histologic inflammation and HRQoL. These post hoc analyses evaluated whether reduced clinical, endoscopic, and histologic disease activity were uniquely associated with improved HRQoL for adults with active mild-to-moderate UC receiving once-daily 4.8 g/day multimatrix mesalazine for 8 weeks. METHODS: Assessments at baseline and week 8 (i.e., treatment completion) included clinical and endoscopic activity (modified UC-Disease Activity Index), histology (Geboes scoring), and HRQoL (Short Inflammatory Bowel Disease Questionnaire [SIBDQ]; SF-12v2® Health Survey [SF-12v2]). Associations among each type of disease activity and HRQoL were examined by correlations and by mean changes in SIBDQ and SF-12v2 scores between disease activity subgroups (e.g., achievement of clinical remission; mucosal healing). Regression models estimated unique variance in HRQoL accounted by each type of disease activity. RESULTS: Within the analysis sample (n = 717), patients with reduced clinical and endoscopic activity had significantly larger improvements in all HRQoL domains (p < 0.001), as did patients in both endoscopic and clinical remission compared to patients in endoscopic remission only (p < 0.05). Patients with histologic activity post-treatment scored significantly worse on all HRQoL domains than patients with no activity (p < 0.05). Correlations and regression models found that decreases in clinical and endoscopic activity were associated with improvements in HRQoL domain scores. CONCLUSIONS: Clinical symptoms and mucosal health have separable, distinct impacts on UC patients' HRQoL.

Efficacy of systemic treatments for moderate to severe plaque psoriasis: systematic review and meta-analysis.

AIMS: To compare the efficacy of psoriasis treatments through a systematic literature review and meta-analysis. METHODS: Randomized controlled trials evaluating the Psoriasis Area and Severity Index (PASI) were identified and assessed for quality. PASI responses were modeled using a mixed-treatment comparison, which enabled the estimation of the relative effectiveness of several treatments. Sensitivity analyses were performed. RESULTS: Twenty-two trials were included. Tumor necrosis factor (TNF) inhibitors were most likely to achieve PASI 75, with a mean relative risk (RR) of 15.57 (95% CI 12.46-19.25) versus mean RRs of 9.24 (95% CI 5.33-13.91) for systemic and 5.65 (95% CI 3.74-7.97) for T-cell therapies. Infliximab (81%) and adalimumab (71%) had greater probabilities of achieving PASI 75 than etanercept (50%). Dosage was an important determinant of outcome. CONCLUSIONS: TNF inhibitors were more effective than T cell agents; adalimumab and infliximab were more effective than systemic therapies and etanercept. Evidence-based comparisons support patient and physician decisions.

Health-Related Quality of Life and Work-Related Outcomes for Patients With Mild-to-Moderate Ulcerative Colitis and Remission Status Following Short-Term and Long-Term Treatment With Multimatrix Mesalamine: A Prospective, Open-Label Study.

Background: Disease activity of patients with ulcerative colitis (UC) predicts health-related quality of life (HRQL) and work-related outcomes (eg, absenteeism, productivity). We tested whether outcomes differed among patients in complete (clinical and endoscopic) remission, partial remission, or not in remission following treatment with multimatrix mesalamine. Methods: Data were from an open-label, multicountry, prospective trial (ClinicalTrials.gov identifier: NCT01124149) of 717 adults with active mild-to-moderate UC treated with 4.8 g/day multimatrix mesalamine tablets for 8 weeks (induction period); 459 patients who achieved partial or complete remission received daily 2.4 g/day multimatrix mesalamine for 12 additional months (maintenance period). HRQL (SF-12v2 Health Survey and Short Inflammatory Bowel Disease Questionnaire) and work-related outcomes (Work Productivity and Activity Impairment questionnaire) were assessed at baseline and final visits of each treatment period. Differences in scores by remission status within each treatment period were tested using analysis of variance and analysis of covariance models, whereas mixed-effects models with repeated measures tested changes over time. Results: At their final visit of each treatment period, patients in partial remission scored significantly better on all HRQL and work-related domains than patients not in remission (all Bonferroni-adjusted P < 0.05). Scores for patients in partial remission were, almost without exception, statistically equivalent to those for patients in complete remission. Fluctuating between complete and partial remission during maintenance treatment had no impact on outcomes. Conclusions: Patients in partial remission following multimatrix mesalamine treatment had HRQL and work-related outcomes equivalent to patients in complete remission. Achievement and maintenance of partial remission may be sufficient for improvements in patients' functioning, well-being, and work performance.

Changes in health-related quality of life and work-related outcomes for patients with mild-to-moderate ulcerative colitis receiving short-term and long-term treatment with multimatrix mesalamine: a prospective, open-label study.

BACKGROUND: Ulcerative colitis (UC) is associated with lower health-related quality of life (HRQoL), and with disease activity predicting lower HRQoL and worse work-related outcomes. The current study examined the burden of UC on patients' HRQoL, as well as changes in patients' HRQoL and work-related outcomes following short-term and long-term treatment with multimatrix mesalamine, and their correspondence with changes in disease activity. METHODS: Data were from an open-label, multinational, prospective trial (ClinicalTrials.gov identifier: NCT01124149) of 717 adults with active mild-to-moderate UC who were treated with 4.8 g/day multimatrix mesalamine tablets once daily for eight weeks (acute phase). Four-hundred sixty-one patients who achieved partial or complete clinical and endoscopic remission subsequently received treatment with daily 2.4 g/day multimatrix mesalamine for 12 months (maintenance phase). At baseline, Week 8, and Month 12, patients were administered patient-reported outcomes (PRO) measures of HRQoL (the SF-12v2® Health Survey [SF-12v2] and Short Inflammatory Bowel Disease Questionnaire) and work-related outcomes (Work Productivity and Activity Impairment questionnaire, UC-specific version). SF-12v2 scores were compared to the U.S. general population using Analysis of Variance models to assess burden of UC on HRQoL. Mixed-effects repeated-measures models compared PRO scores across visits to assess change in PRO scores over time. Correlations examined the correspondence of changes in PRO scores with changes on a modified UC disease activity index (UC-DAI). RESULTS: Baseline burden of disease observed on all SF-12v2 domains was partially eliminated at Week 8 and completely eliminated at Month 12. Statistically significant improvements from baseline were observed at both Week 8 and Month 12 for all PRO scores (all P < 0.001). Decreases in UC-DAI scores significantly predicted improvements in PRO scores during the acute treatment phase. CONCLUSIONS: Patients with UC receiving daily multimatrix mesalamine treatment showed significant improvements in all measured domains of HRQoL and work-related outcomes. Patients who achieved partial or complete clinical and endoscopic remission maintained these improvements for most of these domains over 12 months with continued daily treatment. Changes in HRQoL and work-related outcomes were inversely related to changes in disease activity. Findings support the effectiveness of multimatrix mesalamine for improving, and sustaining improvements, in HRQoL and work-related outcomes.

Impact of adalimumab treatment on patient-reported outcomes: results from a Phase III clinical trial in patients with moderate to severe plaque psoriasis.

OBJECTIVE: The effect of adalimumab on patient-reported outcomes (PROs) was evaluated in patients with moderate to severe psoriasis during the initial 16-week, double-blind period of a 52-week, Phase III, multicenter trial. METHODS: Patients were randomized to placebo or adalimumab 80 mg at Week 0 and 40 mg every other week from Week 1 to Week 15. PROs were evaluated throughout the study and included the Dermatology Life Quality Index (DLQI), the Short Form 36 Health Survey (SF-36), the Work Productivity and Activity Impairment Questionnaire-Specific Health Problem (WPAI-SHP), and several patient-rated symptom scales. RESULTS: The adalimumab-treated group reported significantly greater improvements in DLQI total score (p<0.001), SF-36 Physical Component Summary score (p<0.001), and Mental Component Summary score (p<0.001) compared with the placebo-treated group over 16 weeks. Significant differences, favoring adalimumab, were also seen for the DLQI subscale scores (p < 0.001); SF-36 scale scores (p<0.001); WPAI-SHP work impairment (p<0.001), activity limitation (p<0.001), and overall work impairment scores (p<0.001); patient's global assessment of disease severity (p<0.001), psoriasis pain (p<0.001), and psoriasis-related pruritus (p = 0.002). CONCLUSION: Adalimumab was efficacious in improving dermatology-specific and general health-related quality of life, work and activity limitations, and psoriasis-related symptoms in patients with moderate to severe psoriasis over a 16-week period.

The validity and responsiveness of three quality of life measures in the assessment of psoriasis patients: results of a phase II study.

BACKGROUND: Patient-reported outcome (PROs) measures are being used more frequently in investigational studies of treatments for moderate to severe plaque psoriasis. The objective of this study was to examine the relationships among the Dermatology Life Quality Index (DLQI), the Short Form 36 (SF-36), and the EuroQOL 5D (EQ-5D) and to assess their validity, responsiveness, and estimates of minimum important differences. METHODS: A Phase II, randomized, double-blind, parallel group, placebo-controlled, multi-center clinical trial assessed the clinical efficacy and safety of two doses of subcutaneously administered adalimumab vs. placebo for 12 weeks in the treatment of 147 patients with moderate to severe plaque psoriasis. This study provided the opportunity to evaluate the validity and responsiveness to change in clinical status of PROs instruments. Patients completed the DLQI, SF-36, and EQ-5D questionnaires at baseline and at 12 weeks. Blinded investigators assessed the Psoriasis Area and Severity Index (PASI) scores and the Physician's Global Assessment (PGA) scores of enrolled patients. The responsiveness of the measures to changes in the clinical endpoints from baseline to Week 12 was assessed. Estimates of minimum important differences (MID) were derived. All analyses were performed with blinded data; findings and conclusions were not biased based on treatment condition. RESULTS: The dermatology-specific DLQI was highly correlated to clinical endpoints at baseline and at Week 12, and was the most responsive PRO to changes in endpoints. Compared with the SF-36, the EQ-5D index score and VAS scores were generally more highly correlated with clinical endpoints, but displayed about the same degree of responsiveness. The most responsive SF-36 scales were the Bodily Pain and Social Functioning scales. Estimates of the MID for the DLQI ranged from 2.3-5.7 and for the SF-36 Physical Component Summary (PCS) score ranged from 2.5-3.9. CONCLUSION: This study provides support for the continued use of the DLQI and SF-36 PCS in the assessment of treatments for psoriasis. On the basis of the results from this trial, the EQ-5D should be considered as a general PRO measure in future clinical trials of patients with moderate to severe plaque psoriasis.
