Abstract
BACKGROUND Systemic sclerosis (SSc) is a chronic autoimmune disease that affects the connective tissues and leads to physical, emotional, and social challenges for patients. Evaluating health-related quality of life (HRQoL) with a disease-specific tool may be preferable for improving patient care and treatment outcomes. The aim of this study was to translate the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into Turkish and to investigate its psychometric properties. METHODS Eighty-six patients with SSc (mean age 51.8 ± 11.7 years, 80 females) participated in the study. Convergent validity was explored by correlation analyses between Turkish SScQoL and Short-Form 36 (SF-36), European Quality of Life Survey-5 Dimensions (EQ-5D), EQ-5D Visual Analog Scale (EQ-VAS), and Scleroderma Health Assessment Questionnaire (SHAQ). Cronbach's alpha was calculated to test internal consistency. Turkish SScQoL was readministered after 7-14 days to fifty-eight patients for determining test re-test reliability. Intraclass correlation coefficients in 95% confidence interval (ICCs [95%CI]) were calculated to examine the agreement between two assessments. Values greater than 15% and an absolute skewness value < 1 were recognized as the presence of a floor or ceiling effect. RESULTS SScQoL correlated significantly with SF-36 subdomains (r = -0.347 to -0.618, p < 0.01), EQ-5D (r = -0.535, p < 0.01), EQ-VAS (r = -0.636, p < 0.01), and SHAQ global score (r = 0.521, p < 0.01). SScQoL demonstrated excellent internal consistency (Cronbach's alpha = 0.917), and good to excellent test-retest reliability (ICC [95%CI] = 0.85 [0.76-0.91]). No floor/ceiling effects were observed. CONCLUSION The Turkish version of SScQoL seems to have adequate psychometric properties and can be used to evaluate HRQoL in clinical and research settings. Key points • Turkish version of SScQoL is a valid and reliable tool for measuring health-related quality of life of patients with systemic sclerosis. • SScQoL is the only diseases-specific quality of life measurement for systemic sclerosis available in Turkish. • Patients with limited and diffuse SSc seem to be similar in terms of self-reported health-related quality of life.

Abstract
(1) Background: Systemic sclerosis (SSc) is characterized by significant fatigue, causing diminished quality of life (QoL). The aim of this study was to examine fatigue levels and their associations with clinical factors and determine the minimal clinically important difference (MCID) value for the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-FS). (2) Methods: A total of 160 SSc patients and 62 individuals without SSc were followed-up over a 12-month period by measuring the FACIT-FS and the Visual Analogue Scale and the Short Form 36 Vitality Score analyzing changes in exhaustion. (3) Results: Fatigue was strongly correlated with HRQoL, level of pain, emotional disorders, physical capability and functionality. The MCID values for FACIT-FS were calculated as -3 for deterioration and +4 for improvement after a 12-month follow-up. The predictors of improvement of fatigue from baseline parameters were the significant disease activity, the patients' poorer functionality and the short disease duration. Patients with scleroderma-related interstitial lung disease at baseline had approximately tripled risks for worsening fatigue. The independent influential factors regarding the changing of FACIT-FS were improving or worsening in the same direction in reference to physical condition, gastrointestinal and emotional factors. (4) Conclusions: Fatigue is a multi-dimensional symptom, which is strongly correlated to HRQoL. MCID values of FACIT-FS can be useful tools in monitoring the changes of HRQoL in clinical trials and in daily practice among patients with SSc.

Abstract
OBJECTIVES In SSc patients, disease specific determinants that influence health-related quality of life (HRQoL) over time have not been described. We aim to, in patients with SSc, (i) evaluate if and how HRQoL changes over time, and (ii) assess how different SSc domains and functional impairments contribute to changes in HRQoL over time. METHODS All SSc patients from the Leiden SSc cohort were included; patients with disease duration <24 months were classified as incident cases. HRQoL was assessed prospectively on an annual basis using the EQ-5D and the SF36. To assess baseline associations between clinical characteristics and HRQoL, linear regressions were performed. To identify possible associations between SSc characteristics and HRQoL change over time, linear mixed models were performed in both incident and prevalent cases. RESULTS In total, 492 SSc patients were included (n = 202 incident cases), with a median follow-up duration of 3.4 years. At baseline, presence of organ involvement was independently associated with a worse SF36 physical component score and lower EQ-5D score. Over time, gastrointestinal symptoms, Raynaud and digital ulcers were independently associated with deterioration of HRQoL in both incident and prevalent cases. In prevalent cases, pulmonary arterial hypertension (PAH) was associated with a decrease in HRQoL over time. Worse functioning as measured by six-min walking distance, mouth-opening, finger-to-palm distance and grip-strength contributed significantly to deterioration of HRQoL over time. CONCLUSION In SSc, key clinical burdens that contribute to worsening of HRQoL over time include digital ulcers, Raynaud and gastrointestinal involvement. In addition, PAH is a significant burden in prevalent disease.

Abstract
AbstractIn systemic sclerosis (SSc) therapeutic efforts are often directed to prevent progressive respiratory impairment, but it is unclear to what extent changes in pulmonary function tests (PFTs) are associated with health-related quality of life (HRQoL). The aim of our study is to evaluate how modifications in PFTs contribute to longitudinal variations in HRQoL, assessed through the multidimensional questionnaire EQ-5D, in patients with SSc. We included SSc patients with forced vital capacity (FVC%), diffusing capacity of the lungs for carbon monoxide (DLCO%) and EQ-5D assessed in at least two visits. The EQ-5D consists of two parts, a utility score ranging from − 0.59 to 1, and a 0–100 Visual Analogue Scale (VAS). Higher values represent better health. The association between changes in FVC% and DLCO%, and evolution of EQ-5D over time, was investigated using generalized estimating equations. Three hundred seventy-eight patients were included, accounting for a total of 1619 measurements. The models showed that improvement in FVC% is significantly associated with increase in both utility score (β = 0.001; 95% CI 0.000 to 0.002; p = 0.003) and VAS over time (β = 0.188; 95% CI 0.111 to 0.264; p < 0.001). Moreover, improvement in DLCO% is longitudinally associated with increase in utility score (β = 0.001; 95% CI 0.000 to 0.002; p = 0.038), while the results for VAS were non-significant (β = 0.020; 95% CI -0.079 to 0.120; p = 0.690). We show that change in PFTs has a significant, although minor, impact on HRQoL as measured by EQ-5D in SSc.Key Points• In patients with SSc, changes in PFTs have a significant, although minor, impact on HRQoL.• In patients with SSc-ILD, the perception of HRQoL is nearly not influenced by changes in pulmonary function.• The use of generic questionnaires might not be sensitive enough to evaluate the impact on quality of life of therapies targeting specific SSc manifestations.

Abstract
The steadily increasing knowledge regarding pathogenetic mechanisms in autoimmune rheumatic diseases has paved the way to different therapeutic approaches. In particular, the market entry of biologics has dramatically modified the natural history of rheumatic chronic inflammatory diseases with a meaningful impact on patients’ quality of life. Among the wide spectrum of available biological treatments, rituximab (RTX), first used in the treatment of non-Hodgkin’s lymphoma, was later approved for rheumatoid arthritis and anti-neutrophil cytoplasmic antibodies-associated vasculitis. Nowadays, in rheumatology, RTX is also used with off-label indications in patients with systemic sclerosis, Sjögren’s syndrome and systemic lupus erythematosus. RTX is a monoclonal antibody directed to CD20 molecules expressed on the surfaces of pre-B and mature B lymphocytes. It acts by causing apoptosis of these cells with antibody- and complement-dependent cytotoxicity. As inflammatory responses to cell-associated immune complexes are key elements in the pathogenesis of several autoimmune rheumatic diseases, such an approach might be effective in these patients. In fact, RTX, by promoting the rapid and long-term depletion of circulating and lymphoid tissue-associated B cells, leads to a lower recruitment of these effector cells at sites of immune complex deposition, thus reducing inflammation and tissue damage. RTX is of the most interest to rheumatologists as it represents an important additional therapeutic approach. Thus, the advent in clinical practice of approved RTX biosimilars, such as CT-P10, may be of help in improving treatment access as well as in reducing costs.

Abstract
OBJECTIVES To assess subjective swallowing difficulties (SD) with medication intake and their practical consequences in patients suffering from systemic sclerosis (SSc) with a novel self-report questionnaire. DESIGN AND SETTING Based on a systematic literature review, we developed a self-report questionnaire and got it approved by an expert panel. Subsequently, we sent the questionnaire by post mail to SSc patients of the European Center for the Rehabilitation of Scleroderma Rheinfelden, Switzerland. PARTICIPANTS Patients were eligible if they were diagnosed with SSc, treated at the center, and were of age ≥18 years at the study start. MAIN OUTCOME MEASURES Prevalence and pattern of SD with oral medication intake, including localization and intensity of complaints. RESULTS The questionnaire consisted of 30 items divided into five sections Complaints, Intensity, Localization, Coping strategies, and Adherence. Of the 64 SSc patients eligible in 2014, 43 (67%) returned the questionnaire. Twenty patients reported SD with medication intake (prevalence 47%), either currently (11; 26%) or in the past that had been overcome (9; 21%). Self-reported SD were localized mostly in the larynx (43%) and esophagus (34%). They were of moderate (45%) or strong to unbearable intensity (25%). Modification of the dosage form was reported in 40% of cases with SD. Adherence was poor for 20 (47%) patients and was not associated with SD (p=0.148). CONCLUSION Our novel self-report questionnaire is able to assess the pattern of complaints linked to medication intake, that is, localization and intensity. It may serve as a guide for health care professionals in selecting the most suitable therapy option, enabling tailored counseling to reduce inappropriate medication modifications.
