Abstract

Gastrointestinal (GI) involvement is almost universal in patients with systemic sclerosis (SSc) and is associated with significant disease-related morbidity and mortality.1 The entire GI tract can be involved and other disease features (eg, low mood, terminal organ failure and functional hand impairment) can result in significant nutritional impairment. Severe GI involvement has been reported to occur in ~10% of patients with SSc and often occurs early in the course of the disease.2 However, identification of patients at high risk of clinically significant weight loss is extremely challenging, including from the high prevalence of GI symptoms in patients with SSc. Therefore, there is a need to understand high-risk patients including potentially modifiable risk factors, with a view to early intervention strategies. Against this background, the aim of this study was to examine potential clinical risk factors of significant weight loss in patients with SSc. We performed an analysis of patients with SSc enrolled in the multinational, longitudinal European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) database. In our study, we defined significant weight loss as 4.5 kg and/or least 5% of their body weight at 5 months onwards.3 Patients with a recorded second visit after 3 months and before 12 months were included in the analysis. We adopted a pragmatic approach (relevant to clinical practice) in …

Abstract

ObjectivesTo determine the causes of death and risk factors in systemic sclerosis (SSc).MethodsBetween 2000 and 2011, we examined the death certificates of all French patients with SSc to determine causes of death. Then we examined causes of death and developed a score associated with all-cause mortality from the international European Scleroderma Trials and Research (EUSTAR) database. Candidate prognostic factors were tested by Cox proportional hazards regression model by single variable analysis, followed by a multiple variable model stratified by centres. The bootstrapping technique was used for internal validation.ResultsWe identified 2719 French certificates of deaths related to SSc, mainly from cardiac (31%) and respiratory (18%) causes, and an increase in SSc-specific mortality over time. Over a median follow-up of 2.3 years, 1072 (9.6%) of 11 193 patients from the EUSTAR sample died, from cardiac disease in 27% and respiratory causes in 17%. By multiple variable analysis, a risk score was developed, which accurately predicted the 3-year mortality, with an area under the curve of 0.82. The 3-year survival of patients in the upper quartile was 53%, in contrast with 98% in the first quartile.ConclusionCombining two complementary and detailed databases enabled the collection of an unprecedented 3700 deaths, revealing the major contribution of the cardiopulmonary system to SSc mortality. We also developed a robust score to risk-stratify these patients and estimate their 3-year survival. With the emergence of new therapies, these important observations should help caregivers plan and refine the monitoring and management to prolong these patients’ survival.

Abstract

The c-kit gene encodes a transmembrane receptor (KIT) with tyrosine kinase activity which is a specific target for anti-cancer therapy. We investigated KIT expression in a group of patients with early-stage malignant melanoma. Primary tumour specimens obtained from 261 radically resected patients with stage I and II malignant melanoma were examined for KIT expression. Formalin-fixed, paraffin embedded tissues were stained with the polyclonal rabbit anti-human anti-KIT antibody (Dako Cytomation Inc., Carpenteria, California, USA). Patients were classified into four groups according to the level of expression (0%,30%, 30-60% and60%). Univariate and multivariate analyses examining the impact of KIT expression, Breslow thickness, Clark level and microscopic ulceration on disease-free survival were performed. Within the population of 261 patients with early-stage melanoma with 62 recurrences during a follow-up of 64 months, KIT expression was found in 144 cases (55%). KIT was expressed in more than 60% of cells in 20 patients (8%), in 30-60% of cells in 64 patients (24%) and in less than 30% of cells in 60 patients (23%). KIT expression was not found in 117 patients (45%). In univariate analyses, the influence of KIT expression on disease-free survival was not proven (P=0.4956; log-rank test). Increasing Breslow thickness, a higher Clark level, the presence of microscopic ulceration and a higher stage were significantly associated with a shorter disease-free survival (P0.0001; log-rank test in all cases). In multivariate analysis, Breslow thickness, stage and KIT expression were significant negative prognostic factors for a shorter disease-free survival (P0.0001, P=0.0028, P=0.0488, respectively; stepwise Cox regression model). It can be concluded that KIT is expressed in more than one-half of early-stage malignant melanoma. KIT may serve as an additive prognostic factor to Breslow thickness and stage within the tested population. The therapeutic impact of KIT expression in malignant melanoma is uncertain. Results of ongoing pilot phase II studies may validate the efficacy of imatinib mesylate in malignant melanoma expressing KIT.

Abstract

Objectives. IL-35 is a member of the IL-12 family consisting of p35/IL-12a and EBI3/IL-27b subunits. IL-35 exerts immunomodulatory activities in experimental and human autoimmune inflammatory conditions. Our aim was to assess IL-35 expression in the skin and circulation of SSc patients and to characterize its potential association with SSc-related features. Methods. Expression of IL-35 in skin and dermal fibroblasts was quantified by quantitative PCR, immunohistochemistry and immunofluorescence. Serum levels of IL-35 (by ELISA), CRP (by turbidimetry), ANA (by immunofluorescence) and autoantibodies of the ENA complex (by immunoblot) were measured in 40 SSc patients. Serum IL-35 was determined in 40 age- and sex-matched healthy controls. Results. IL-35 expression was increased in SSc skin and dermal fibroblasts in a TGF-β-dependent manner. IL-35 induced an activated phenotype in resting fibroblasts and enhanced the release of collagen. IL-35 serum levels were increased in patients with SSc compared with healthy controls [median 83.9 (interquartile range 45.1–146.1) vs 36.2 (interquartile range 17.2–49.4) pg/ml, P < 0.0001]. Serum IL-35 was negatively correlated with disease duration (r = −0.4339, P = 0.0052). In line with this finding, serum IL-35 was increased in patients with an early SSc pattern on capillaroscopy assessment compared with those with active and late SSc patterns. Conclusion. The present study demonstrates overexpression of IL-35 in SSc skin, dermal fibroblasts and serum. TGF-β induces IL-35, which in turn activates resting fibroblasts and enhances the release of collagen, thereby contributing to aberrant TGF-β signalling in SSc. Increased serum IL-35 is associated with early, inflammatory stages of SSc.

Abstract

ObjectiveTo identify a core set of preliminary items considered as important for the very early diagnosis of systemic sclerosis (SSc).MethodsA list of items provided by European League Against Rheumatism (EULAR) Scleroderma Trial and Research(EUSTAR) centres were subjected to a Delphi exercise among 110 experts in the field of SSc. In round 1, experts were asked to choose the items they considered as the most important for the very early diagnosis of SSc. In round 2, experts were asked to reconsider the items accepted after the first stage. In round 3, the clinical relevance of selected items and their importance as measures that would lead to an early referral process were rated using appropriateness scores.ResultsPhysicians from 85 EUSTAR centres participated in the study and provided an initial list of 121 items. After three Delphi rounds, the steering committee, with input from external experts, collapsed the 121 items into three domains containing seven items, developed as follows: skin domain (puffy fingers/puffy swollen digits turning into sclerodactily); vascular domain (Raynaud's phenomenon, abnormal capillaroscopy with scleroderma pattern) and laboratory domain (antinuclear, anticentromere and antitopoisomerase-I antibodies). Finally, the whole assembly of EUSTAR centres ratified with a majority vote the results in a final face-to-face meeting.ConclusionThe three Delphi rounds allowed us to identify the items considered by experts as necessary for the very early diagnosis of SSc. The validation of these items to establish diagnostic criteria is currently ongoing in a prospective observational cohort.
