Abstract

Objectives To characterize patients with positive anti-topoisomerase I (ATA) in lcSSc. Methods SSc patients enrolled in the EUSTAR cohort with a disease duration of ≤3 years at database entry were considered. We assessed the risk of major organ involvement in the following groups: ATA-lcSSc vs ACA-lcSSc and vs ANA without specificity (ANA)-lcSSc, and ATA-lcSSc vs ATA-dcSSc. Cox regression models with time-dependent covariates were performed with the following outcomes: new-onset interstitial lung disease (ILD), ILD progression [forced vital capacity (FVC) decline ≥10% and ≥5% vs values at ILD diagnosis), primary myocardial involvement (PMI), pulmonary hypertension (PH), any organ involvement and all-cause mortality. Results We included 1252 patients [194 ATA-lcSSc (15.5%)], with 7.7 years (s.d. 3.5) of follow-up. ILD risk was higher in ATA-lcSSc vs ACA- and ANA-lcSSc and similar to ATA-dcSSc, although with less frequent restrictive lung disease. The risk of FVC decline ≥10% (35% of ATA-lcSSc) was lower in ATA-lcSSc than in ATA-dcSSc, whereas FVC decline ≥5% occurs similarly between ATA-lcSSc (58% of patients) and other SSc subsets, including ATA-dcSSc. The risk of PMI was similar in ATA-lcSSc and ANA-lcSSc but lower than in ACA-lcSSc; no difference in PH and mortality risk was observed among lcSSc subsets. The risk of any organ involvement, PMI and PH was lower and the mortality tended to be lower in ATA-lcSSc vs ATA-dcSSc. Conclusion ATA-lcSSc patients have a high risk of ILD, albeit with a lower risk of progression compared with ATA-dcSSc, supporting careful screening for ILD in this subgroup.

Abstract

Objectives To estimate the prevalence of long-term exposure to glucocorticoids (GCs) and to identify factors associated with, and variations in prescribing practices over time and across recruiting countries. Methods We included patients with SSc having a visit recorded in the EUSTAR database from January 2013 onward. We analysed the prevalence and the main features of GCs users, their exposure to GCs over time, and their GCs dosages. Multivariable linear regression was used to analyse the factors identified as associated with GCs intake duration. Time trends, and variations in GCs utilization across recruiting countries were explored. Missing data were imputed using multiple imputation with chained equations. Results The 9819 patients included were mostly females (85%), the majority had lcSSc (73%), and the median age was 58 years. At baseline, 34% of patients (n = 2769/8109) (48% dcSSc vs 29% lcSSc) were on GCs, and the median dose was 7.5 mg/day. GCs users were more frequently males and anti-Scl70 positive, and more commonly had dcSSc and more severe disease. On average, GCs users spent 25% of their follow-up time (median 33.2 months) on GCs, with no significant between-subsets difference. Notably, 33% (n = 971/2959) and 22% (n = 647/2959) of patients followed up for >1 year had received GCs for >6 and >12 months, respectively. Multivariable analysis showed that patient and disease characteristics poorly explained the variability in GCs exposure (adjusted-R2 = 0.06, P Conclusions GCs are widely and long-term prescribed in SSc, with significant between-countries and within-country differences. A gradual decrease in their utilization has been observed.

Abstract

Background: The current subclassification of systemic sclerosis into cutaneous subtypes does not fully capture the heterogeneity of the disease. We aimed to compare the performances of stratification into LeRoy's cutaneous subtypes versus stratification by autoantibody status in systemic sclerosis. Methods: For this cohort study, we assessed people with systemic sclerosis in the multicentre international European Scleroderma Trials and Research (EUSTAR) database. Individuals positive for systemic-sclerosis autoantibodies of two specificities were excluded, and remaining individuals were classified by cutaneous subtype, according to their systemic sclerosis-specific autoantibodies, or both. We assessed the performance of each model to predict overall survival, progression-free survival, disease progression, and different organ involvement. The three models were compared by use of the area under the curve (AUC) of the receiver operating characteristic and the net reclassification improvement (NRI). Missing data were imputed. Findings: We assessed the database on July 26, 2019. Of 16 939 patients assessed for eligibility, 10 711 patients were included: 1647 (15·4%) of 10 709 were male, 9062 (84·6%) were female, mean age was 54·4 (SD 13·8) years, and mean disease duration was 7·9 (SD 8·2) years. Information regarding cutaneous subtype was available for 10 176 participants and antibody data were available for 9643 participants. In the prognostic analysis, there was no difference in AUC for overall survival (0·82, 95% CI 0·81–0·84 for cutaneous only vs 0·84, 0·82–0·85 for antibody only vs 0·84, 0·83–0·86 for combined) or for progression-free survival (0·70, 0·69–0·71 vs 0·71, 0·70–0·72 vs 0·71, 0·70–0·72). However, at 4 years the NRI showed substantial improvement for the antibody-only model compared with the cutaneous-only model in prediction of overall survival (0·57, 0·46–0·71 for antibody only vs 0·29, 0·19–0·39 for cutaneous only) and disease progression (0·36, 0·29–0·46 vs 0·21, 0·14–0·28). The antibody-only model did better than the cutaneous-only model in predicting renal crisis (AUC 0·72, 0·70–0·74 for antibody only vs 0·66, 0·64–0·69 for cutaneous only) and lung fibrosis leading to restrictive lung function (AUC 0·76, 0·75–0·77 vs 0·71, 0·70–0·72). The combined model improved the prediction of digital ulcers and elevated systolic pulmonary artery pressure, but did poorly for cardiac involvement. Interpretation: The autoantibody-only model outperforms cutaneous-only subsetting for risk stratifying people with systemic sclerosis in the EUSTAR cohort. Physicians should be aware of these findings at the time of decision making for patient management. Funding: World Scleroderma Foundation.

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

Background Human polyomavirus (HPyV)6 and HPyV7 are shed chronically from human skin. HPyV7, but not HPyV6, has been linked to a pruritic skin eruption of immunosuppression. Objective We determined whether biopsy specimens showing a characteristic pattern of dyskeratosis and parakeratosis might be associated with polyomavirus infection. Methods We screened biopsy specimens showing "peacock plumage" histology by polymerase chain reaction for HPyVs. Cases positive for HPyV6 or HPyV7 were then analyzed by immunohistochemistry, electron microscopy, immunofluorescence, quantitative polymerase chain reaction, and complete sequencing, including unbiased, next-generation sequencing. Results We identified 3 additional cases of HPyV6 or HPyV7 skin infections. Expression of T antigen and viral capsid was abundant in lesional skin. Dual immunofluorescence staining experiments confirmed that HPyV7 primarily infects keratinocytes. High viral loads in lesional skin compared with normal-appearing skin and the identification of intact virions by both electron microscopy and next-generation sequencing support a role for active viral infections in these skin diseases. Limitation This was a small case series of archived materials. Conclusion We have found that HPyV6 and HPyV7 are associated with rare, pruritic skin eruptions with a distinctive histologic pattern and describe this entity as "HPyV6- and HPyV7-associated pruritic and dyskeratotic dermatoses."

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

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

The principal pool of epidermal stem cells is located in the bulge region of the hair follicle root sheath. In this research project, we have used a refined procedure to isolate porcine hair follicles including their root sheath and for comparison purposes also human cell material. These cells migrating from the hair follicles were then cytochemically characterized. A panel of antibodies and two labeled plant lectins were tested on cell material obtained under a range of assorted experimental conditions. Due to their role in growth regulation we also studied two endogenous lectins, specifically monitoring their expression and the presence of accessible ligands. These in vitro results were compared with findings on porcine and human hair follicles and human basal cell carcinomas in situ. The keratinocytes originating from hair follicles in the presence of feeder cells are rather undifferentiated and express galectin-1/galectin-1-binding sites but not galectin-3 in their nuclei associated with DeltaNp63alpha positivity. Nuclear reactivity for galectin-1 was rarely observed in the bulge of the outer root sheath of the human hair follicle and of basal cell carcinomas and absent in porcine tissue samples. Exclusion of feeder cells from our cultivation system of porcine hair follicles led to the formation of spheroid bodies from these keratinocytes. Ki67 as a marker of proliferation was not present in the nuclei of cells forming these spheroids. One part of these bodies is positive for markers of post-mitotic differentiated cells, while the other spheroids are composed of poorly differentiated cells, which are able to adhere to feeder cells and form growing colonies. In summary, the detection of galectin-1 and also nuclear binding sites for this endogenous effector points to intracellular functionality of this lectin. It can be considered a potential marker of a distinct cell population, probably at the beginning of a differentiation cascade of keratinocytes.

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.

Abstract

Therapy targeting immune checkpoints represents an integral part of the treatment for patients suffering from advanced melanoma. However, the mechanisms of resistance are responsible for a lower therapeutic outcome than expected. Concerning melanoma, insufficient stimulation of the immune system by tumour neoantigens is a likely explanation. As shown previously, radiotherapy is a known option for increasing the production of tumour neoantigens and their release into the microenvironment. Consequently, neoantigens could be recognized by antigen presenting cells (APCs) and subjected to effector T lymphocytes. Enhancing the immune reaction can trigger the therapeutic response also at distant metastases, a phenomenon known as an abscopal effect (from “ab scopus”, that is, away from the target). To illustrate this, we present the case of a 78-year old male treated by anti-CTLA-4/ipilimumab for metastatic melanoma. The patient received the standard four doses of ipilimumab administered every three weeks. However, the control CT scans detected disease progression in the form of axillary lymph nodes metastasis and liver metastasis two months after ipilimumab. At this stage, palliative cryotherapy of the skin metastases was initiated to alleviate the tumour burden. Surprisingly, the effect of cryotherapy was also observed in untreated metastases and deep subcutaneous metastases on the back. Moreover, we observed the disease remission of axillary lymph nodes and liver metastasis two months after the cryotherapy. The rarity of the abscopal effect suggests that even primed anti-tumour CD8+ T cells cannot overcome the tumour microenvironment’s suppressive effect and execute immune clearance. However, the biological mechanism underlying this phenomenon is yet to be elucidated. The elicitation of a systemic response by cryotherapy with documented abscopal effect was rarely reported, although the immune response induction is presumably similar to a radiotherapy-induced one. The report is a combination case study and review of the abscopal effect in melanoma treated with checkpoint inhibitors.
