Objectives Nailfold videocapillaroscopy (NVC) plays a well-established role in differentiating primary from secondary RP due to SSc. However, the association of NVC with novel severe organ involvement/progression in SSc has never been evaluated in a multicentre, multinational study, which we now perform for the first time. Methods Follow-up data from 334 SSc patients [265 women; 18 limited SSc (lSSc)/203 lcSSc/113 dcSSc] registered between November 2008 and January 2016 by seven tertiary centres in the EUSTAR-database, were analysed. Novel severe organ involvement/progression was defined as new/progressive involvement of the peripheral vasculature, lungs, heart, skin, gastrointestinal tract, kidneys, musculoskeletal system, or death, at the 12- or 24-month follow-up. NVC images at enrolment were quantitatively and qualitatively evaluated according to the standardized definitions of the EULAR Study Group on Microcirculation in Rheumatic Diseases. Uni- and multivariable logistic regression modelling (ULR, MLR) was performed. Results Of the 334 included SSc patients, 257 (76.9%) developed novel overall severe organ involvement/progression. Following MLR, normal capillary density was associated with less-frequent novel overall severe organ involvement/progression [odds ratio (OR) = 0.77, P  < 0.001] and novel peripheral vascular involvement (OR = 0.79, P   =  0.043); microhaemorrhages were associated with less novel pulmonary hypertension (OR = 0.47, P   =  0.029); and a 'severe' (active/late) NVC pattern was associated with novel overall severe organ involvement/progression (OR = 2.14, P   =  0.002) and skin progression (OR = 1.70, P   =  0.049). Conclusions Our results suggest that NVC may be a promising biomarker in SSc, certainly warranting further investigation. Despite the participation of tertiary centres, which follow their patients in a standardized way, we were underpowered to detect associations with infrequent severe organ involvement/progression.

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 FROM AUTHOR]

Objectives In IgG4-related disease (IgG4-RD), relapse including recurrent organ involvement (ROI) and de novo organ involvement (DNOI) occurs frequently during the clinical course. This study aimed to clarify the differences between the risk factors underlying ROI and DNOI in IgG4-RD. Methods We retrospectively investigated factors related to ROI and DNOI in 86 IgG4-RD patients. For assessment of factors related to ROI and DNOI, we performed uni- and multivariate Cox regression analyses. On stepwise multivariate analysis, we applied the variables with P < 0.1 in the univariate analysis and the predictors of relapse suggested in past reports. Results During the mean follow-up period of 63.1 months, ROI was detected at 1.0–120 months after diagnosis in 20 patients, 4 of whom were not receiving glucocorticoid (GC) at the time of ROI. In contrast, DNOI was detected at 5.0–120 months after diagnosis in 15 patients, 8 of whom were not receiving GC at the time of DNOI. In the multivariate analysis, blood eosinophil counts at diagnosis [per 100/μl; hazard ratio (HR) 1.072 (95% CI 1.018, 1.129)] and continuation of GC [ vs discontinuation or observation without GC; HR 0.245 (95% CI 0.076, 0.793)] had a significant impact on the time to DNOI, whereas age [HR 0.942 (95% CI 0.899, 0.986)] and ANA positivity [ vs negativity; HR 6.632 (95% CI 1.892, 23.255)] had a significant impact on the time to ROI. Conclusion The present study suggests that the risk factors of ROI and DNOI are different in IgG4-RD, highlighting the need for different preventative strategies. [ABSTRACT FROM AUTHOR]

Objective. LcSSc is associated with ACAs and a mild course, whereas dcSSc is associated with anti-topoisomerase antibodies (ATAs) and a more severe course. However, ATAs are also present in lcSSc. Little is known about survival and organ involvement in this subgroup. The aim of this study is to determine whether survival and organ involvement of lcSSc ATA-positive patients differs from lcSSc ATA-negative or dcSSc ATA-positive patients. Furthermore, transition from lcSSc to dcSSc was evaluated. Methods. Data from The Nijmegen Systemic Sclerosis cohort were used, with up to 15 years of follow-up. Kaplan--Meier analysis was performed for survival and organ involvement, including interstitial lung disease, pulmonary arterial hypertension, cardiac involvement and Scleroderma Renal Crises. Cox proportional hazard modelling was performed to adjust for confounders. Results. A total of 460 patients were included: 58 (13%) lcSSc ATA-positive patients, 237 (52%) lcSSc ATA-negative patients and 78 (17%) dcSSc ATA-positive patients. Cumulative survival in lcSSc ATA-positive patients was 75%, in lcSSc ATA-negative patients 58% and in dcSSc ATA-positive patients 53%. Interstitial lung disease was more prevalent in lcSSc ATA-positive patients (49%) than in lcSSc ATA-negative patients (25%), but less than in dcSSc ATA-positive patients (60%). Forty-eight patients developed dcSSc: 24 ATA-negative and 24 ATA-positive (P < 0.001). Conclusion. LcSSc ATA-positive patients differ from lcSSc ATA-negative patients and dcSSc ATA-positive patients concerning survival and organ involvement. LcSSc patients who are ATA-positive are more likely to develop dcSSc than lcSSc patients who are ATA negative. [ABSTRACT FROM AUTHOR]

Objective. The aim of the present study was to explore the long-term outcome and clinical characteristics of adult patients with juvenile onset in the EULAR Scleroderma Trials and Research (EUSTAR) cohort and compare them with adult patients with onset between 20 and 40 years of age.Methods. From the EUSTAR SSc cohort two patient groups were analysed: patients with juvenile SSc (jSSc) who are adults at present, and patients diagnosed between the age of 20 and 40 years (aSSc). Demographic data of the patients, organ involvement and outcome of the disease were examined using the Minimal Essential Data Set database system.Results. From 5000 patients in the EUSTAR cohort, 60 patients (1.2%) with jSSc and 910 patients (18%) with aSSc were selected according the inclusion criteria. In the jSSc group, the mean age of disease onset was 12.4 years (range 2–15.9 years), and in the aSSc group, the mean age was 32 years (range 20–40 years). Disease subsets were similar. The antibody profile was also comparable except for ACAs, which were positive in 5% of the jSSc group and 26.9% of the aSSc group (P < 0.005). Organ involvement (lung, kidney, joint, muscle and heart) was similar in the two groups of patients at the time of the last follow-up.Conclusion. The subset distribution in the jSSc and aSSc cohorts was found to be similar. Only the frequency of ACAs was significantly lower in the jSSc, which supports the hypothesis that the SSc patients with paediatric onset in the adult cohort may represent a distinct subgroup of the complete cohort of paediatric patients.
