1.  The substantial burden of systemic lupus erythematosus on the productivity and careers of patients: a European patient-driven online survey 
Rheumatology (Oxford, England)  2013;52(12):2292-2301.
Objective. The objective of this study was to explore the burden of SLE and its effect on patients’ lives.
Methods. The Lupus European Online (LEO) survey included patient-designed questions on demographics, SLE diagnosis, and the impact of SLE on careers. Three SLE-specific patient-reported outcome (PRO) questionnaires were also completed: the Lupus Quality of Life (LupusQoL), the Fatigue Severity Scale (FSS), and the Work Productivity and Activity Impairment (WPAI)-Lupus v2.0. The survey was available online in five languages from May through August 2010. All self-identified SLE participants were eligible to respond. Survey results were analysed using descriptive statistics. Multivariate linear regression explored factors contributing to impaired productivity.
Results. Of the 2070 European SLE patients completing the survey, 93.1% were women, 86.7% were aged <50 years and 71.8% had a college or university education. More than two-thirds of respondents (69.5%) reported that SLE affected their careers; 27.7% changed careers within a year of diagnosis. All LupusQoL domains (score range 0–100) were impaired, with fatigue (median domain score 43.8) being the most affected and intimate relationships (median domain score 75.0) the least. Most patients (82.5%) reported fatigue (FSS score ≥4). Productivity was impaired across all WPAI domains, both at work and in general activities. Fatigue, an inability to plan and reduced physical health were significantly associated with impaired productivity. Patients whose careers were affected by SLE had worse health-related quality of life, more fatigue and worse productivity than patients whose careers were not affected.
Conclusion. LEO survey respondents reported that SLE negatively affects their daily lives, productivity and career choices.

2.  Certolizumab pegol plus methotrexate provides broad relief from the burden of rheumatoid arthritis: analysis of patient-reported outcomes from the RAPID 2 trial 
Annals of the Rheumatic Diseases  2011;70(6):996-1002.
Objective
To assess the impact of certolizumab pegol (CZP) on patient-reported outcomes (PROs) in rheumatoid arthritis (RA), and to interpret these results using number needed to treat (NNT), and associations between PRO responses and longer term outcomes.
Methods
A total of 619 patients with active RA were randomised to CZP 200 or 400 mg, or placebo plus methotrexate (MTX). PROs assessed included pain, patient's global assessment of disease activity (PtGA), physical function, fatigue and health-related quality of life. Treatment impact on PROs, NNT to achieve simultaneous improvements in multiple PROs and correlations between PROs were calculated. Times to onset of improvements greater than or equal to minimum clinically important differences (MCIDs) in pain as a determinant of clinical outcomes at week 24 were compared between week 6 and 12 responders, and in patients with improvements in pain ≥MCID at week 12 (week 12 responders/non-responders).
Results
CZP 200 and 400 mg plus MTX were associated with rapid, clinically meaningful improvements in all PROs. The NNT for subjects to report changes ≥MCID in up to five PROs was two to three, and five for all six PROs (pain, PtGA, physical function, fatigue and short-form 36-item Physical and Mental Component Summary Scores). More patients with improvements ≥MCID in pain at week 6 than those at week 12 had lower disease activity at week 24. Week 12 pain responders had better clinical outcomes at week 24 than non-responders.
Conclusions
The data demonstrate that CZP provides broad relief from the burden of RA.

3.  Rapid and sustained improvements in health-related quality of life, fatigue, and other patient-reported outcomes in rheumatoid arthritis patients treated with certolizumab pegol plus methotrexate over 1 year: results from the RAPID 1 randomized controlled trial 
Arthritis Research & Therapy  2009;11(6):R170.
Introduction
The objective of this study was to assess the impact of certolizumab pegol (CZP) treatment on health-related quality of life (HRQoL), fatigue and other patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA).
Methods
Patients with active RA (N = 982) were randomized 2:2:1 to subcutaneous CZP (400 mg at weeks 0, 2 and 4; followed by CZP 200 mg or 400 mg) plus methotrexate (MTX) every other week, or placebo (PBO) plus MTX. PRO assessments included HRQoL, fatigue, physical function, arthritis pain and disease activity. Adjusted mean changes from baseline in all PROs were obtained using analysis of covariance (ANCOVA) applying last observation carried forward (LOCF) imputation. The proportion of patients achieving clinically meaningful improvements in each PRO was obtained using logistic regression and by applying non-responder imputation to missing values after rescue medication or withdrawal. The correlations between PRO responses and clinical responses were also assessed by tetrachoric correlation using non-responder imputation.
Results
Patients treated with CZP plus MTX reported significant (P < 0.001), clinically meaningful improvements in HRQoL at the first assessment (week 12); reductions in fatigue, disease activity and pain and improvements in physical function were reported at week 1. In particular, CZP-treated patients reported improvements in mental health. Mean changes from baseline in the SF-36 Mental Component Summary (MCS) at week 52 for CZP 200 mg and 400 mg plus MTX, and PBO plus MTX were 6.4, 6.4 and 2.1, respectively (P < 0.001). In addition, mental health and vitality scores in CZP-treated patients approached age- and gender-adjusted US population norms. Improvements in all PROs were sustained. Similar benefits were reported with both CZP doses. Changes in SF-36 MCS scores had the lowest correlation with disease activity scores (DAS28) and American College of Rheumatology 20% improvement (ACR20) response rates, while improvements in pain showed the highest correlation.
Conclusions
Treatment with CZP plus MTX resulted in rapid and sustained improvements in all PROs, indicating that the benefits of CZP extend beyond clinical efficacy endpoints into areas that are more relevant and meaningful for patients on a daily basis.
