Is cyclophosphamide still the gold standard in early severe rapidly progressive systemic sclerosis? Autoimmun Rev 2024; 23:103439. [PMID: 37690478 DOI: 10.1016/j.autrev.2023.103439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 08/28/2023] [Indexed: 09/12/2023]
Abstract
Cyclophosphamide (CYC) has been a gold standard of treatment for severe progressive Systemic Sclerosis (SSc), especially in patients with concomitant interstitial lung disease (ILD). This approach was based on results of several interventional studies, including randomized control trials, which mainly addressed SSc-ILD as a primary end point and skin involvement as a second one. The use of CYC is time-limited due to significant adverse events. More recently, other immunosuppressive and biological agents showed efficacy but better safety profile in patients with SSc and SSc-ILD. With regards to other end-points, post-hoc analyses, systematic reviews and metalysis showed that CYC had limited influence on patients' quality of life, event-free survival and mortality. Comprehensive patient's stratification according to a molecular, cellular and phenotypic pattern may help in choosing of personalized medicine with more ambitious treatment effect and should be the future direction. According to the above available data and even if scientific evidence may be missing, experts' opinion has changed the attitude to CYC as an anchor drug in the management of severe SSc. Indeed, CYC has been pushed to the second and even third treatment option after mycophenolate mofetil, tocilizumab or rituximab. This position became obvious during debate on this topic at CORA meeting 2023.

Riociguat in patients with early diffuse cutaneous systemic sclerosis (RISE-SSc): open-label, long-term extension of a phase 2b, randomised, placebo-controlled trial. THE LANCET. RHEUMATOLOGY 2023; 5:e660-e669. [PMID: 38251533 DOI: 10.1016/s2665-9913(23)00238-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 08/17/2023] [Accepted: 08/29/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND The phase 2b Riociguat Safety and Efficacy in Patients with Diffuse Cutaneous Systemic Sclerosis (RISE-SSc) trial investigated riociguat versus placebo in early diffuse cutaneous systemic sclerosis. The long-term extension evaluated safety and exploratory treatment effects for an additional year. METHODS Patients were enrolled to RISE-SSc between Jan 15, 2015, and Dec 8, 2016. Those who completed the 52-week, randomised, parallel-group, placebo-controlled, double-blind phase were eligible for the long-term extension. Patients originally assigned to riociguat continued therapy (riociguat-riociguat group). Those originally assigned to placebo were switched to riociguat (placebo-riociguat group), adjusted up to 2·5 mg three times daily in a 10-week, double-blind dose-adjustment phase, followed by an open-label phase. Statistical analyses were descriptive. Safety including adverse events and serious adverse events was assessed in the long-term safety analysis set (all patients randomly assigned and treated with study medication in the double-blind phase who continued study medication in the long-term extension). The RISE-SSc trial is registered with ClinicalTrials.gov, NCT02283762. FINDINGS In total, 87 (72%) of 121 patients in the main RISE-SSc study entered the long-term extension (riociguat-riociguat, n=42; placebo-riociguat, n=45). 65 (75%) of 87 patients were women, 22 (25%) were men, and 62 (71%) were White. Overall, 82 (94%) of 87 patients in the long-term extension had an adverse event; most (66 [76%] of 87) were of mild to moderate severity, with no increase in pulmonary-related serious adverse events in patients with interstitial lung disease. INTERPRETATION No new safety signals were observed with long-term riociguat in patients with early diffuse cutaneous systemic sclerosis. Study limitations include the absence of a comparator group in this open-label extension study. FUNDING Bayer and Merck Sharp & Dohme.

Efficacy and Safety of Lenabasum, a Cannabinoid Type 2 Receptor Agonist, in a Phase 3 Randomized Trial in Diffuse Cutaneous Systemic Sclerosis. Arthritis Rheumatol 2023; 75:1608-1618. [PMID: 37098795 DOI: 10.1002/art.42510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 02/22/2023] [Accepted: 03/14/2023] [Indexed: 04/27/2023]
Abstract
OBJECTIVE This phase 3 study was undertaken to investigate the efficacy and safety of lenabasum, a cannabinoid type 2 receptor agonist, in patients with diffuse cutaneous systemic sclerosis (dcSSc). METHODS A multinational double-blind study was conducted in 365 dcSSc patients who were randomized and dosed 1:1:1 with lenabasum 20 mg, lenabasum 5 mg, or placebo, each twice daily and added to background treatments, including immunosuppressive therapies (IST). RESULTS The primary end point, the American College of Rheumatology combined response index in dcSSc (CRISS) at week 52 for lenabasum 20 mg twice a day versus placebo, was not met, with CRISS score of 0.888 versus 0.887 (P = 0.4972, using mixed models repeated measures [MMRM]). The change in the modified Rodnan skin thickness score (MRSS) at week 52 for lenabasum 20 mg twice a day versus placebo was -6.7 versus -8.1 (P = 0.1183, using MMRM). Prespecified analyses showed higher CRISS scores, greater improvement in MRSS, and lower decline in forced vital capacity in patients on background mycophenolate and those who were taking IST for ≤1 year. No deaths or excess in serious or severe adverse events related to lenabasum were observed. CONCLUSION A benefit of lenabasum in dcSSc was not demonstrated. Most patients were treated with background IST, and treatment with mycophenolate mofetil in particular was associated with better outcomes. These findings support the use of IST in the treatment of dcSSc and highlight the challenge of demonstrating a treatment effect when investigational treatment is added to standard of care IST. These findings have relevance to trial design in SSc, as well as to clinical care.

A Phase II randomized controlled trial of oral prednisolone in early diffuse cutaneous systemic sclerosis (PRedSS). Rheumatology (Oxford) 2023; 62:3133-3138.

Abstract
OBJECTIVES Although the painful and disabling features of early diffuse cutaneous SSc (dcSSc) have an inflammatory basis and could respond to corticosteroids, corticosteroids are a risk factor for scleroderma renal crisis. Whether or not they should be prescribed is therefore highly contentious. Our aim was to examine safety and efficacy of moderate-dose prednisolone in early dcSSc. METHODS PRedSS set out as a Phase II, multicentre, double-blind randomized controlled trial, converted to open-label during the Covid-19 pandemic. Patients were randomized to receive either prednisolone (∼0.3 mg/kg) or matching placebo (or no treatment during open-label) for 6 months. Co-primary endpoints were the HAQ Disability Index (HAQ-DI) and modified Rodnan skin score (mRSS) at 3 months. Over 20 secondary endpoints included patient reported outcome measures reflecting pain, itch, fatigue, anxiety and depression, and helplessness. Target recruitment was 72 patients. RESULTS Thirty-five patients were randomized (17 prednisolone, 18 placebo/control). The adjusted mean difference between treatment groups at 3 months in HAQ-DI score was -0.10 (97.5% CI: -0.29, 0.10), P = 0.254, and in mRSS -3.90 (97.5% CI: -8.83, 1.03), P = 0.070, both favouring prednisolone but not significantly. Patients in the prednisolone group experienced significantly less pain (P = 0.027), anxiety (P = 0.018) and helplessness (P = 0.040) than control patients at 3 months. There were no renal crises, but sample size was small. CONCLUSION PRedSS was terminated early primarily due to the Covid-19 pandemic, and so was underpowered. Therefore, interpretation must be cautious and results considered inconclusive, indicating the need for a further randomized trial.

A data-driven approach finds RNA polymerase III antibody and tendon friction rubs as enrichment tools for early diffuse scleroderma trials. Rheumatology (Oxford) 2023; 62:1543-1551. [PMID: 36031807 PMCID: PMC10072884 DOI: 10.1093/rheumatology/keac501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/27/2022] [Accepted: 07/29/2022] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVE Clinical trials in early diffuse SSc have consistently shown a placebo group response with a declining modified Rodnan skin score (mRSS), with negative outcomes. Our objective was to identify strategies using clinical characteristics or laboratory values to improve trial design. METHODS We identified early diffuse SSc patients first seen at the University of Pittsburgh from 1980-2015. Eligible patients had ≥3 visits, with at least two mRSS scores within the first year of follow-up. We performed Kaplan-Meier analyses, group-based trajectory analysis of mRSS scores, followed by multivariable regression analysis and classification tree analysis. We applied the results to the abatacept in early diffuse systemic sclerosis (ASSET) trial outcome data. RESULTS We identified 403 patients with <18 months, and 514 with <36 months disease duration. The median number of mRSS follow-up scores was 14 (interquartile range 8, 25). All methodologic approaches identified skin thickness progression rate, RNA polymerase III (RNAP3) antibody positivity and presence of tendon friction rubs (TFR) as predictors of mRSS trajectory over 5 years of follow-up, and thereby as potential enrichment variables. When applied to the ASSET data, adjustment for both RNAP3 and TFR demonstrated reduction of the placebo mRSS response, particularly at 6 months. A significant difference in the ACR Composite Response Index in Systemic Sclerosis (CRISS) score was found with adjustment by RNAP3 at 6 months, and TFR or RNAP3 at 12 months. CONCLUSION Adjustment for both RNAP3 and TFR predicts mRSS trajectory and diminished the mRSS decline in ASSET placebo group, and identified significant differences in CRISS. RNAP3, particularly, is a stratification or enrichment approach to improve early diffuse SSc trial design.

Impact of Innovative Treatment Using Biological Drugs for the Modulation of Diffuse Cutaneous Systemic Sclerosis: A Systematic Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020247. [PMID: 36837449 PMCID: PMC9967997 DOI: 10.3390/medicina59020247] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/19/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023]
Abstract
Scleroderma or systemic sclerosis (SSc) is an autoimmune disease affecting the connective tissue, characterized by fibrosis of the skin and internal organs. There is currently no curative treatment available, so therapeutic action is aimed at a symptomatic treatment of the affected organs. The development of biotechnology has made it possible to implement certain biological drugs that could represent a window of opportunity to modulate the evolution and symptomatology of scleroderma with greater efficacy and less toxicity than conventional treatments. This study aimed to review the current evidence critically and systematically on the effects of biological drugs on the pulmonary function, skin disease, and health status of patients afflicted by diffuse cutaneous systemic sclerosis (dcSSc). Three electronic databases (Pubmed, Dialnet, and Cochrane Library Plus) were systematically searched until the cut-off date of October 2022. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included original articles in English and Spanish with a controlled trial design, comparing biological drug treatments (tocilizumab, belimumab, riociguat, abatacept, and romilkimab) with a control group. The methodological quality of the studies was assessed using the McMaster quantitative form and the PEDro scale. A total of 383 studies were identified, 6 of them met the established criteria and were included in the present systematic review. A total of 426 patients treated with tocilizumab, belimumab, riociguat, abatacept, and romilkimab were included. The results showed substantial non-significant (p < 0.05) improvement trends after treatment with the biological drugs included in this review for the modified Rodnan Scale Value, Forced Vital Capacity, and Carbon Monoxide Diffusion Test; however, no benefits were shown on the Health Assessment Questionnaire-Disability Index when compared to the control group. Biological drugs, therefore, maybe a new therapeutic strategy for dcSSc and could be recommended as an additional and/or adjunctive treatment that promotes anti-fibrotic activity. This review could further define the clinical rationale for the use of biologics in the treatment of dcSSc and could provide key details on the study protocol, design, and outcome reporting.

Machine-learning classification identifies patients with early systemic sclerosis as abatacept responders via CD28 pathway modulation. JCI Insight 2022; 7:155282.

Abstract
Here, the efficacy of abatacept in patients with early diffuse systemic sclerosis (dcSSc) was analyzed to test the hypothesis that patients in the inflammatory intrinsic subset would show the most significant clinical improvement. Eighty-four participants with dcSSc were randomized to receive abatacept or placebo for 12 months. RNA-Seq was performed on 233 skin paired biopsies at baseline and at 3 and 6 months. Improvement was defined as a 5-point or more than 20% change in modified Rodnan skin score (mRSS) between baseline and 12 months. Samples were assigned to intrinsic gene expression subsets (inflammatory, fibroproliferative, or normal-like subsets). In the abatacept arm, change in mRSS was most pronounced for the inflammatory and normal-like subsets relative to the placebo subset. Gene expression for participants on placebo remained in the original molecular subset, whereas inflammatory participants treated with abatacept had gene expression that moved toward the normal-like subset. The Costimulation of the CD28 Family Reactome Pathway decreased in patients who improved on abatacept and was specific to the inflammatory subset. Patients in the inflammatory subset had elevation of the Costimulation of the CD28 Family pathway at baseline relative to that of participants in the fibroproliferative and normal-like subsets. There was a correlation between improved ΔmRSS and baseline expression of the Costimulation of the CD28 Family pathway. This study provides an example of precision medicine in systemic sclerosis clinical trials.

Paclitaxel-induced diffuse scleroderma with possible scleroderma-renal crisis: a case report and literature review of taxanes-induced scleroderma. Clin Rheumatol 2022; 41:3887-3896. [PMID: 36085204 PMCID: PMC9462648 DOI: 10.1007/s10067-022-06364-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 08/31/2022] [Accepted: 09/01/2022] [Indexed: 11/30/2022]
Abstract
Introduction/objectives Scleroderma is a rare complication in taxanes therapy. Although individual cases of taxanes-induced scleroderma have been reported, the clinical manifestation and treatment outcomes were reviewed and summarized rarely. This study reported a patient who developed diffuse scleroderma and possible scleroderma renal crisis after paclitaxel therapy for ureter cancer. Method A PubMed literature review on published cases of taxanes-induced scleroderma up until April 2022 was included for analysis. Results The search identified 27 patients with adequate information for analysis. Of the 28 patients, including the one presented here, 22 were female. Peripheral edema was the most common symptom in all but one patient, and often accompanied by erythema in 11. Symptoms usually occurred in half of the patients within the 4th course of treatment. Skin lesions gradually progressed to skin fibrosis, and extended proximally. Internal organ involvements were uncommon. Antinuclear antibody tests were positive occasionally, but anti-Scl70 and anti-centromere usually were negative. Taxanes therapy was discontinued, continued and unavailable in 21, 3, and 4 patients, respectively. Corticosteroids for skin lesions with or without immunosuppressive drugs were given to 15 patients. Of 25 patients with available skin outcomes, 19 improved. There was no significant skin improvement between those who did or did not receive skin treatment (62.5% vs. 75.0%, p = 0.37). Skin usually improved after discontinuing taxanes. Conclusion Taxanes-induced scleroderma is different from idiopathic scleroderma. Physicians should be aware of this condition in order to provide early diagnosis and apply appropriate management in order to avoid serious complications from severe skin sclerosis. Key Points | • Scleroderma is a rare but unique and serious complication of taxanes therapy • Skin manifestations and distribution are similar to idiopathic scleroderma, but vascular phenomenon, internal organ involvement and scleroderma-associated auto-antibodies are presented rarely. Skin improvement usually occurs shortly after discontinuing taxanes • The role of immunosuppressive therapy in treating taxanes-induced scleroderma is not clear |

New composite endpoint in early diffuse cutaneous systemic sclerosis: revisiting the provisional American College of Rheumatology Composite Response Index in Systemic Sclerosis. Ann Rheum Dis 2021; 80:641-650.

Abstract
OBJECTIVES American College of Rheumatology Composite Response Index in Systemic Sclerosis (ACR-CRISS) is a composite endpoint to assess the likelihood of improvement in diffuse systemic sclerosis. ACR-CRISS is a weighted score and includes five core set measures: modified Rodnan skin score, FVC% predicted, health assessment questionnaire-disability index, and patient and clinician global assessments. METHODS We analysed core set measures from 354 participants who participated in three placebo-controlled trials. We generated 10 development datasets, randomly selected from 2/3 of the participants, stratified by study and treatment group. The remaining participants (1/3 of the participants) formed the validation sets. Risk differences (RDs) between active and placebo treatments were calculated by averaging over the replicate datasets; bootstrap 95% CIs for the RDs to estimate the magnitude of treatment effects. RESULTS In the development sets (n=237), the proportion of participants in the active group had statistically higher improvement in >1 of 5 core set measures versus the placebo group. For example, the proportion who improved by ≥20% in ≥3 core set measures was 49.4% in the active versus338.9% in the placebo; RD: 10.5%, 95% CI4.9 % to 16.1%. In the validation sets (n=117), the proportion who improved by ≥20% in ≥3 core set measures was 50.3% in the active versus35.63% in the placebo (RD:114.8%, 95% CI 3.1% to225.7%). Similar trends were seen with larger percentage cut-offs. CONCLUSION Revised CRISS, as assessed by the proportion of participants who improved by a certain percentage in ≥3 of 5 core set measures, is a potential new composite outcome measure.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a chronic, autoimmune connective tissue disease associated with high morbidity and mortality, especially in diffuse cutaneous SSc (dcSSc). Currently, there are several treatments available in early dcSSc that aim to change the disease course, including immunosuppressive agents and autologous haematopoietic stem cell transplantation (HSCT). HSCT has been adopted in international guidelines and is offered in current clinical care. However, optimal timing and patient selection for HSCT are still unclear. In particular, it is unclear whether HSCT should be positioned as upfront therapy or rescue treatment for patients refractory to immunosuppressive therapy. We hypothesise that upfront HSCT is superior and results in lower toxicity and lower long-term medical costs. Therefore, we propose this randomised trial aiming to determine the optimal treatment strategy for early dcSSc by comparing two strategies used in standard care: (1) upfront autologous HSCT versus (2) immunosuppressive therapy (intravenous cyclophosphamide pulse therapy followed by mycophenolate mofetil) with rescue HSCT in case of treatment failure. METHODS AND ANALYSIS The UPSIDE (UPfront autologous hematopoietic Stem cell transplantation vs Immunosuppressive medication in early DiffusE cutaneous systemic sclerosis) study is a multicentre, randomised, open-label, controlled trial. In total, 120 patients with early dcSSc will be randomised. The primary outcome is event-free survival at 2 years after randomisation. Secondary outcomes include serious adverse events, functional status and health-related quality of life. We will also evaluate changes in nailfold capillaroscopy pattern, pulmonary function, cardiac MR and high-resolution CT of the chest. Follow-up visits will be scheduled 3-monthly for 2 years and annually in the following 3 years. ETHICS AND DISSEMINATION The study was approved by the Dutch Central Committee on Research Concerning Human Subjects (NL72607.041.20). The results will be disseminated through patient associations and conventional scientific channels. TRIAL REGISTRATION NUMBERS NCT04464434; NL 8720.

Abstract
OBJECTIVE Intravenous iloprost improves Raynaud's phenomenon (RP) and promotes healing of digital ulcers in systemic sclerosis (SSc; scleroderma). Despite a short half-life, its clinical efficacy lasts weeks. Endothelial adherens junctions, which are formed by VE-cadherin clustering between endothelial cells (ECs), regulate endothelial properties including barrier function, endothelial-to-mesenchymal transition (EndoMT), and angiogenesis. We undertook this study to investigate the hypothesis that junctional disruption contributes to vascular dysfunction in SSc, and that the protective effect of iloprost is mediated by strengthening of those junctions. METHODS Dermal ECs from SSc patients and healthy controls were isolated. The effect of iloprost on ECs was examined using immunofluorescence, permeability assays, Matrigel tube formation, and quantitative polymerase chain reaction. RESULTS Adherens junctions in SSc were disrupted compared to normal ECs, as indicated by reduced levels of VE-cadherin and increased permeability in SSc ECs (P < 0.05). Iloprost increased VE-cadherin clustering at junctions and restored junctional levels of VE-cadherin in SSc ECs (mean ± SD 37.3 ± 4.3 fluorescence units) compared to normal ECs (mean ± SD 29.7 ± 3.4 fluorescence units; P < 0.05), after 2 hours of iloprost incubation. In addition, iloprost reduced permeability of monolayers, increased tubulogenesis, and blocked EndoMT in both normal and SSc ECs (n ≥ 3; P < 0.05). The effects in normal ECs were inhibited by a function-blocking antibody that prevents junctional clustering of VE-cadherin. CONCLUSION Our data suggest that the long-lasting effects of iloprost reflect its ability to stabilize adherens junctions, resulting in increased tubulogenesis and barrier function and reduced EndoMT. These findings provide a mechanistic basis for the use of iloprost in treating SSc patients with RP and digital ulcers.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a multi-dimensional connective tissue disease of unknown etiology. Given the immense clinical complexity of SSc, the treatment of this condition is not standardized and considerable heterogeneity exists in SSc management approaches. The purpose of this article is to highlight novel therapeutic strategies and new medications under development for the treatment of systemic sclerosis (SSc). AREAS COVERED Herein, the authors focus primarily on recently completed clinical trials and phase 3 and 4 clinical trials of therapeutic agents that show promise in SSc. This review is organized by the clinical complications that occur in SSc, for which novel treatment strategies are under study. EXPERT OPINION Combining therapies to address the individual manifestations of SSc is a cornerstone to the comprehensive management of this condition. Therapeutic strategies must take into account the organs involved, the level of disease activity in each area, and the disease stage. Controlling the complex biological network, progressive vasculopathy and fibrosis, as well as manifestations of end-organ dysfunction are all critical considerations when determining the best treatment approach for SSc.

Abstract
We treated skin sclerosis with triple therapy consisting of a glucocorticoid, intravenous cyclophosphamide, and double-filtration plasmapheresis. The objective of this study was to analyze its effectiveness in a case series of patients who received triple therapy.We enrolled 8 patients with diffuse cutaneous systemic sclerosis (dcSSc) who received triple therapy at our hospital from 2008 to 2016. We analyzed the mean change in the modified Rodnan skin score (mRSS), percentage of the predicted forced vital capacity (%FVC), percentage of the predicted carbon monoxide diffusing capacity (%DLCO), and serum KL-6 levels from baseline to follow-up.All patients were treated with an intermediate dose of oral prednisolone (30.6 ± 2.1 mg/day) initially. The mean cumulative dose of intravenous cyclophosphamide was 1.4 ± 0.2 g. The mean mRSS decreased significantly at follow-up compared with that at baseline (27.0 ± 3.3 vs 15.8 ± 3.5; P = .03). At the end of the treatment, the mean %FVC and %DLCO were improved moderately, although the differences were not significant. The serum KL-6 levels decreased from 578.9 ± 146.5 to 205.3 ± 43.1 U/ml (P = .02). No significant correlation was found between the change in mRSS or disease duration and the initial skin score severity.Triple therapy may improve skin sclerosis, with effectiveness equal or superior to other reported treatments. This preliminary case series demonstrates the potential of triple therapy for treating dcSSc. However, prospective studies with long-term follow-up should be performed to assess its role.

Abatacept in Early Diffuse Cutaneous Systemic Sclerosis: Results of a Phase II Investigator-Initiated, Multicenter, Double-Blind, Randomized, Placebo-Controlled Trial. Arthritis Rheumatol 2020; 72:125-136.

Abstract
OBJECTIVE T cells play a key role in the pathogenesis of early systemic sclerosis. This study was undertaken to assess the safety and efficacy of abatacept in patients with diffuse cutaneous systemic sclerosis (dcSSc). METHODS In this 12-month, randomized, double-blind, placebo-controlled trial, participants were randomized 1:1 to receive either subcutaneous abatacept 125 mg or matching placebo, stratified by duration of dcSSc. Escape therapy was allowed at 6 months for worsening disease. The coprimary end points were change in the modified Rodnan skin thickness score (MRSS) compared to baseline and safety over 12 months. Differences in longitudinal outcomes were assessed according to treatment using linear mixed models, with outcomes censored after initiation of escape therapy. Skin tissue obtained from participants at baseline was classified into intrinsic gene expression subsets. RESULTS Among 88 participants, the adjusted mean change in the MRSS at 12 months was -6.24 units for those receiving abatacept and -4.49 units for those receiving placebo, with an adjusted mean treatment difference of -1.75 units (P = 0.28). Outcomes for 2 secondary measures (Health Assessment Questionnaire disability index and a composite measure) were clinically and statistically significantly better with abatacept. The proportion of subjects in whom escape therapy was needed was higher in the placebo group relative to the abatacept group (36% versus 16%). In the inflammatory and normal-like skin gene expression subsets, decline in the MRSS over 12 months was clinically and significantly greater in the abatacept group versus the placebo group (P < 0.001 and P = 0.03, respectively). In the abatacept group, adverse events occurred in 35 participants versus 40 participants in the placebo group, including 2 deaths and 1 death, respectively. CONCLUSION In this phase II trial, abatacept was well-tolerated, but change in the MRSS was not statistically significant. Secondary outcome measures, including gene expression subsets, showed evidence in support of abatacept. These data should be confirmed in a phase III trial.

Abstract
BACKGROUND scleroderma is an autoimmune disease characterized by organ fibrosis, resistant to standard treatment. It is suspected the addition of Physalis angulata Linn. (Ciplukan) extract as adjuvant therapy can improve the scleroderma skin fibrosis. The aim at this study is to evaluate the effect of ciplukan extract as adjuvant on scleroderma skin fibrosis in standard therapy, based on modified Rodnan skin scale (MRSS), inflammatory biomarkers, immunology and serum fibrosis. METHODS double-blind, randomized clinical trial was performed in scleroderma patients with stable disease at Cipto Mangunkusumo hospital and Hasan Sadikin hospital during November 2015-March 2017 who met the selection criteria and continued to receive standard therapy. The subjects were randomly allocated into two groups: the study group received the ciplukan extract 3 x 250 mg / day for 12 weeks and the placebo group. Examination of MRSS, ESR, P1NP, BAFF and sCD40L was performed every 4 weeks until the end of the study. RESULTS fifty-nine subjects completed the study. They consisted of 29 subjects of the treatment group and 30 of the placebo group, with an average age of 41 (SD 9) years, the proportion of women: male = 9 : 1. There was a significant improvement of skin fibrosis in the study group with a highly significant decrease in MRSS (35.9% VS 6.3%, p <0.001) and a relative decrease in P1NP levels (17.8% VS 0.7%, p = 0.002). No decrease in ESR, BAFF and sCD40L levels in both groups. There was a weak but significant positive correlation between MRSS with P1NP levels (r = 0.236, p = 0.036). CONCLUSION Ciplukan extract with dose 3 x 250 mg for 12 weeks as adjuvant on scleroderma standard therapy alleviates skin fibrosis significantly based on MRSS and P1NP levels.

Simultaneous inhibition of c-Abl and Src kinases abrogates the exaggerated expression of profibrotic genes in cultured systemic sclerosis dermal fibroblasts. Clin Exp Rheumatol 2018; 36 Suppl 113:36-44. [PMID: 30277861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Accepted: 07/23/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVES To examine the effects of simultaneous inhibition of c-Abl and Src kinases on the gene expression and in vitro production of profibrotic molecules by dermal fibroblasts from patients with diffuse systemic sclerosis (SSc) of recent onset. METHODS Dermal fibroblasts from normal individuals or from patients with diffuse cutaneous SSc fulfilling the American College of Rheumatology/EULAR SSc classification criteria were cultured in media containing increasing concentrations of the dual c-Abl and Src kinase inhibitor Bosutinib for 24 h. Total soluble collagen in cell culture supernatants was quantified. Western blots were performed for quantitative assessment of type I collagen, fibronectin, and α-smooth muscle actin (α-SMA) production. Quantitative PCR was performed to examine the effects of Bosutinib on the expression of profibrotic and TGF-β-responsive genes in cultured SSc dermal fibroblasts. RESULTS Simultaneous inhibition of c-Abl and Src kinases with Bosutinib reduced the expression of numerous fibrosis-associated genes including COL1A1, COL1A3, FN, and TGFβ and the production of the corresponding proteins by SSc dermal fibroblasts. Bosutinib also decreased the transition of normal dermal fibroblasts into activated myofibroblasts induced by TGF-β as evidenced by reduction of α-SMA in cell extracts from normal and SSc dermal fibroblasts. CONCLUSIONS Simultaneous inhibition of c-Abl and Src kinases with Bosutinib abrogates the exaggerated expression of genes encoding fibrillar collagens, fibronectin, and TGF-β-responsive genes and reduces type I collagen, fibronectin and α-SMA production by SSc dermal fibroblasts in vitro. Bosutinib also abrogates TGF- β-induced transition of normal fibroblasts to activated myofibroblasts. These results indicate that inhibition of c-Abl and Src kinases activity may be an effective disease modifying antifibrotic therapeutic intervention for SSc.

Abstract
OBJECTIVES This clinical trial was designed to study the safety and efficacy of blocking IL-1 in skin fibrosis of patients with diffuse cutaneous systemic sclerosis (dcSSc), and to test the hypothesis that inhibition of IL-1 by rilonacept will downregulate expression of the 2G SSc gene biomarker as a surrogate for the modified Rodnan skin score (MRSS). METHODS 19 dcSSc patients were randomised 2:1 active treatment:placebo in this double blinded trial. Study patients received weekly treatments with either subcutaneous rilanocept 320 mg loading dose at day 0 and then 160 mg for each of the 5 subsequent weekly doses, or placebo. Skin biopsies were taken to test 2G SSc biomarker gene expression at day 0 before treatment and one week after the final study drug dose, comparing gene expression changes between rilonacept- and placebo-treated patients, as well as the change in gene expression at week 6 compared to baseline in rilonacept-treated patients. Safety assessments extended to 6 weeks after the final dose of study drug or placebo. Other secondary outcome measures included global and IL-1-regulated gene expression, serum biomarkers and the MRSS. RESULTS Rilonacept compared to placebo-treated patients did not show any treatment-related effect on the 2G SSc biomarker. Rilonacept treatment also failed to alter IL-6 expression in skin, serum IL-6, C-reactive protein, or CCL18, a marker of IL-6 activity in SSc. CONCLUSIONS In this small trial we did not observe any effect of blocking IL-1 on clinical skin disease or biomarkers of IL-1 activity.

Abstract
OBJECTIVE To assess the safety and efficacy of treatment with belimumab in patients with early diffuse cutaneous systemic sclerosis (dcSSc) treated with background mycophenolate mofetil (MMF). METHODS In this 52-week, investigator-initiated, single-center, double-blind, placebo-controlled, pilot study, 20 patients with dcSSc recently started on MMF were randomized 1:1 to additionally receive belimumab at 10 mg/kg intravenously or placebo. We assessed safety, efficacy, and differential gene expression. RESULTS In the belimumab group, the median modified Rodnan skin thickness score (MRSS) decreased from 27 (interquartile range [IQR] 26.5, 31) to 18 (IQR 11, 23) (P = 0.039). In the placebo group, the median MRSS decreased from 28 (IQR 22, 28) to 21 (IQR 14, 25) (P = 0.023). The median change in MRSS was -10 (IQR -13, -9) in the belimumab group and -3.0 (IQR -15, -1) in the placebo group (P = 0.411). There were no significant differences between the groups in the number of adverse events (AEs). A significant decrease in expression of B cell signaling and profibrotic genes and pathways was observed in patients with improved MRSS in the belimumab group but not in the placebo group. CONCLUSION Patients in both treatment groups experienced significant improvements in MRSS. The median difference was greater in the belimumab group but did not achieve statistical significance in this small pilot study. AEs were similar between the groups. Changes in gene expression were consistent with mechanism of action and showed that clinical response to treatment with belimumab is associated with a significant decrease in profibrotic genes and pathways. Additional studies are needed to determine the role of belimumab in the treatment of dcSSc.

Inhibition of β-Catenin Signaling in the Skin Rescues Cutaneous Adipogenesis in Systemic Sclerosis: A Randomized, Double-Blind, Placebo-Controlled Trial of C-82. J Invest Dermatol 2017; 137:2473-2483.

Abstract
Several studies have suggested that Wnts might contribute to skin fibrosis in systemic sclerosis (SSc) by affecting the differentiation of pluripotent dermal cells. We tested C-82, a therapeutic that inhibits canonical Wnt signaling by blocking the interaction of the protein CBP with β-Catenin and inhibiting Wnt-activated genes. We used a trial design formulating C-82 for topical application and conducting a placebo-controlled, double-blinded clinical trial in which patients with diffuse cutaneous SSc were treated with C-82 or placebo on opposite forearms. C-82- compared with placebo-treated forearms did not show any clinical effect. Skin biopsies performed before and after treatment showed a very weak trend toward improvement in the C-82-treated skin of biomarkers of local skin disease, THBS1 and COMP. However, on microarray analysis C-82 treatment strongly up-regulated two clusters of genes that correlate negatively with the severity of SSc skin disease. These clusters are highly associated with metabolism and one gene, PLIN2, expressed only by sebocytes and subcutaneous fat cells. These changes in gene expression strongly support a role for Wnts in differentiation of pluripotent cells into profibrotic fibroblasts and the potential for C-82 with longer treatment to promote fat regeneration in SSc skin.

Proteomic Analysis of Sera from Individuals with Diffuse Cutaneous Systemic Sclerosis Reveals a Multianalyte Signature Associated with Clinical Improvement during Imatinib Mesylate Treatment. J Rheumatol 2017; 44:631-638.

Abstract
OBJECTIVE Imatinib has been investigated for the treatment of systemic sclerosis (SSc) because of its ability to inhibit the platelet-derived growth factor receptor and transforming growth factor-β signaling pathways, which have been implicated in SSc pathogenesis. In a 12-month open-label clinical trial assessing the safety and efficacy of imatinib in the treatment of diffuse cutaneous SSc (dcSSc), significant improvements in skin thickening were observed. Here, we report our analysis of sera collected during the clinical trial. METHODS We measured the levels of 46 cytokines, chemokines, and growth factors in the sera of individuals with dcSSc using Luminex and ELISA. Autoantigen microarrays were used to measure immunoglobulin G reactivity to 28 autoantigens. Elastic net regularization was used to identify a signature that was predictive of clinical improvement (reduction in the modified Rodnan skin score ≥ 5) during treatment with imatinib. The signature was also tested using sera from a clinical trial of nilotinib, a tyrosine kinase inhibitor that is structurally related to imatinib, in dcSSc. RESULTS The elastic net algorithm identified a signature, based on levels of CD40 ligand, chemokine (C-X-C motif) ligand 4 (CXCL4), and anti-PM/Scl-100, that was significantly higher in individuals who experienced clinical improvement than in those who did not (p = 0.0011). The signature was validated using samples from a clinical trial of nilotinib. CONCLUSION Identification of patients with SSc with the greatest probability of benefit from treatment with imatinib has the potential to guide individualized treatment. Validation of the signature will require testing in randomized, placebo-controlled studies. Clinicaltrials.gov NCT00555581 and NCT01166139.

Abstract
OBJECTIVES To determine the relationship between vascular biomarkers reflecting the vascular injury and organ involvement in systemic sclerosis (SSc). METHODS Seventy-two SSc patients (66 female) fulfilling 2013 ACR/EULAR Criteria were evaluated. Serum samples of patients were collected for flow-cytometric analysis of sCD40L, tPA, MCP-1, sE-selectin, IL-8, IL-6, VEGF, sP-selectin, TGF-β1 and VCAM levels (Bender MedSystems) in SSc patients and 20 healthy controls. Results were compared with Pearson chi-square/Fisher's and Mann Whitney tests. RESULTS Levels of MCP-1 were found to be elevated in patients with diffuse cutaneous SSc, flexion contractures, FVC<80%, DLCO<80%, pulmonary fibrosis and high acute phase response (p=0.002, p=0.005, p=0.045, p=0.005, p=0.036, p=0.006, respectively), TGF-β1 in patients receiving immunosupressives (p=0.001), sE-selectin in patients with high acute phase response (p=0.028), sCD40L in patients with lcSSc (p=0.011) and smoking habitus (p=0.032). MCP-1 and sE-selectin levels were correlated with disease activity score (r=0.243, p=0.040 and r=0.303, p=0.010), MCP-1 and TGF-β1 were correlated with severity of pulmonary involvement (r=0.323, p=0.006 and r=0.312, p=0.008). CONCLUSIONS MCP-1 was the prominent biomarker correlated with the manifestations related to fibrosis, disease activity score and severity of pulmonary involvement. Treatment and smoking may have an effect on cytokine profile. Vascular biomarkers can be used to predict the characteristics and severity of SSc warranting prospective studies.

Abstract
OBJECTIVES To develop a standardized scoring system to assess the severity of DUs in SSc patients and correlate it with functional outcomes. METHODS In this cross-sectional, longitudinal study in SSc patients with DUs (n=65) we developed a digital ulcers score (DUS) for the assessment of DUs. DUS and the ABILHAND score were measured at each visit and differences were analysed using Tamhane's T2 test. Spearman's Rho test was applied for correlational analysis of DUS and functional outcomes. We calculated a linear regression model using clustered standard errors for correlation analysis between DUS and ABILHAND over time. RESULTS 117 assessments of DUS were performed in 65 SSc patients. Mean DUS was 11.6±1.9 (range: 0-68). Subgroup analyses showed a higher DUS in patients suffering from diffuse cutaneous SSc when compared to patients with limited cutaneous SSc (12.8±3.0 vs. 9.7±2.2 p=0.18). There was no correlation between the DUS and manual ability using the ABILHAND score (overall: n=106 r=-0.138, p=0.22). We observed a small but significant linear correlation between the DUS and the ABILHAND score for a single patient over time (n=14, R2=0.31, r=0.06, p=0.02). CONCLUSIONS The DUS is a feasible scoring instrument to assess severity of DUs in SSc patients. In accordance with the literature the severity of DUs correlates with clinical parameters but also severity of the disease. Further study is needed to establish the DUS as a standardized tool for the assessment of DUs.

Abstract
OBJECTIVES The European Scleroderma Study Group (EScSG) activity index meets nearly all the OMERACT-standards of truth, discrimination and feasibility. The sensitivity to change remains to be attested. This study assesses sensitivity to change of the EScSG activity index in patients with early and severe diffuse cutaneous Systemic Sclerosis (dcSSc) treated with rituximab. METHODS 12-month follow-up (open-label study) of 14 consecutive patients with early dcSSc. Patients received an infusion of two times 1000 mg rituximab at month 0 and 6, together with 100 mg methylprednisolone. Clinical read outs (modified Rodnan skin score [mRSS], lung function and echocardiography) and EScSG activity index were performed at month 0, 3, 6 and 12. Mixed models analyses (MMA) were used to evaluate changes in parameters over time. RESULTS There was a clinically significant change in skin score with a mean (SD) mRSS of 24.8 (4.44) at baseline and 10.4 (3.12) at month 12 (MMA p<0.001). Also the EScSG activity index decreased significantly, with a mean (SD) of 4.3 (1.79) at baseline and 0.7 (0.83) at month 12 (MMA p<0.001). The estimated mean change of the EScSG activity index was -3.6 (95%CI -4.9; -2.4) over 12 months. Indices of internal organ involvement remained stable throughout the study. CONCLUSIONS A significant improvement of the EScSG activity index was observed, in line with the significant improvement of the mRSS and the stabilisation of internal organ involvement. To our knowledge, this is the first study to attest sensitivity to change of the EScSG activity index in the subset of 'early' dcSSc.

Abstract
OBJECTIVES Systemic sclerosis (SSc, scleroderma) is characterised by complex multi-organ pathogenesis, including gastrointestinal tract (GIT) disease that remains poorly characterised. Immunosuppression is commonly used to treat inflammatory manifestations of SSc, including the skin, lungs and joints. There is a paucity of data on the effects of immunosuppression on GIT disease in SSc. METHODS This case report and review of the literature presents two clinical cases in which interleukin-6 (IL-6) antagonism was used for early, diffuse skin disease. RESULTS In these two cases, IL-6 anta-gonism was associated with an exacerbation of GIT symptoms. CONCLUSIONS We postulate that IL-6 is important in the repair of GIT mucosa and further studies are warranted to better understand the effects of immunosuppression on SSc-GIT disease.

Abstract
Less than 10% of the patients with systemic scleroderma develop renal crisis, i.e. acute renal failure and severe hypertension in most cases. Kidney biopsy shows hypertensive arteriolar changes. This complication was lethal until treatment with captopril was introduced in 1976. Since that time the survival of the patients has improved. If treatment is started early, further deteoriation of the kidney may be prevented.

Abstract
OBJECTIVES We aimed to assess the long-term safety and tolerability of imatinib in diffuse cutaneous systemic sclerosis (dcSSc). METHODS In this open-label, single-arm, extension-phase clinical trial, patients continued imatinib for 24 months following 12 months of initial treatment. RESULTS Seventeen patients were enrolled. Forty of 92 adverse events (AE) and 0/6 serious (S) AEs were possibly related to medication. The MRSS decreased from a median of 21 to 16, (p=0.002). CONCLUSIONS This study demonstrates long-term safety and tolerability of imatinib in a substantial proportion of patients with dcSSc. This is important in evaluating the relevance of this therapy in a chronic disease such as SSc.

Abstract
OBJECTIVES Missing data are found in nearly all clinical trials and it is important to use appropriate statistical techniques to analyse clinical trials with missing data. We discuss common statistical methods for tackling missing data and how to handle results when the analyses give different results. METHODS Using data from a placebo-controlled, randomised bovine Type I collagen (CI) study in diffuse cutaneous systemic sclerosis (dcSSc), we apply different statistical approaches to handling missing data. We also describe simple ways to ascertain the type of missing data in the data set, to the extent possible. RESULTS We examine eleven different methods to impute missing data. An analysis based on completers alone (complete case analysis and available case analysis) and the last observation carried forward (LOCF) methods require underlying assumptions which are rarely met in practice. Multiple imputation, mixed effects, and repeated measures try to account for the differences among patients and account for patient's specific response patterns, although the assumption that the missing data is directly related to the observed characteristics may well not be true. The joint likelihood based model combines the mixed effect model and logistic regression model to explicitly handle data not missing at random and so it is more realistic and potentially takes an additional step toward decreasing bias. CONCLUSIONS We discussed various ways of handling missing data and provide recommendations on how to arrive at a conclusion when different statistical approaches to analyse missing data analysis in clinical trials give conflicting answers.

Abstract
IMPORTANCE High-dose immunosuppressive therapy and autologous hematopoietic stem cell transplantation (HSCT) have shown efficacy in systemic sclerosis in phase 1 and small phase 2 trials. OBJECTIVE To compare efficacy and safety of HSCT vs 12 successive monthly intravenous pulses of cyclophosphamide. DESIGN, SETTING, AND PARTICIPANTS The Autologous Stem Cell Transplantation International Scleroderma (ASTIS) trial, a phase 3, multicenter, randomized (1:1), open-label, parallel-group, clinical trial conducted in 10 countries at 29 centers with access to a European Group for Blood and Marrow Transplantation-registered transplant facility. From March 2001 to October 2009, 156 patients with early diffuse cutaneous systemic sclerosis were recruited and followed up until October 31, 2013. INTERVENTIONS HSCT vs intravenous pulse cyclophosphamide. MAIN OUTCOMES AND MEASURES The primary end point was event-free survival, defined as time from randomization until the occurrence of death or persistent major organ failure. RESULTS A total of 156 patients were randomly assigned to receive HSCT (n = 79) or cyclophosphamide (n = 77). During a median follow-up of 5.8 years, 53 events occurred: 22 in the HSCT group (19 deaths and 3 irreversible organ failures) and 31 in the control group (23 deaths and 8 irreversible organ failures). During the first year, there were more events in the HSCT group (13 events [16.5%], including 8 treatment-related deaths) than in the control group (8 events [10.4%], with no treatment-related deaths). At 2 years, 14 events (17.7%) had occurred cumulatively in the HSCT group vs 14 events (18.2%) in the control group; at 4 years, 15 events (19%) had occurred cumulatively in the HSCT group vs 20 events (26%) in the control group. Time-varying hazard ratios (modeled with treatment × time interaction) for event-free survival were 0.35 (95% CI, 0.16-0.74) at 2 years and 0.34 (95% CI, 0.16-0.74) at 4 years. CONCLUSIONS AND RELEVANCE Among patients with early diffuse cutaneous systemic sclerosis, HSCT was associated with increased treatment-related mortality in the first year after treatment. However, HCST conferred a significant long-term event-free survival benefit. TRIAL REGISTRATION isrctn.org Identifier: ISRCTN54371254.

Abstract
Curcumin, or diferuloylmethane, is a crystalline compound which gives the East Asian spice turmeric its bright yellow color. The medicinal properties of this spice have been referenced in numerous countries and cultures throughout the world. Today, there is growing scientific evidence suggesting curcumin's utility in the treatment of chronic pain, inflammatory dermatoses, acceleration of wound closure, skin infections, as well as cosmetic ailments such as dyspigmentation. In addition, curcumin may have a protective role against various pollutants and cytotoxic agents, indicating that it may be beneficial in a mitigational or prophylaxis role. Although turmeric has been used for thousands of years in alternative medicine, curcumin has yet to emerge as a component of our mainstream dermatologic therapeutic armamentarium. Interestingly, curcumin provides an ideal alternative to current therapies because of its relative safety profile even at high doses. Although the advantageous properties of curcumin in medicine are well established, its therapeutic potential thus far has been limited because of its poor oral bioavailablity. Topical administration of curcumin can directly deliver it to the affected tissue making it useful in treating skin-related disorders. However, limitations still exist such as the cosmetically unpleasing bright yellow-orange color, its poor solubility, and its poor stability at a high pH. Here the current literature detailing the potential and current use of curcumin in dermatology is reviewed.

Abstract
Uncontrolled fibrosis in multiple organs is the main cause of death in systemic sclerosis (SSc), and transforming growth factor-β (TGF-β) activation plays a fundamental role in the process. Our previous study demonstrated that miR-21 was significantly up-regulated in SSc fibroblasts. Here, we found that TGF-β regulated the expression of miR-21 and fibrosis-related genes, and decreased Smad7 expression. Over-expression of miR-21 in fibroblasts decreased the levels of Smad7, whereas knockdown of miR-21 increased its expression. Further study using a reporter gene assay demonstrated Smad7 was a direct target of miR-21. Similar to human SSc, the expression of miR-21 increased in the bleomycin induced skin fibrosis. Inhibition of fibrosis by treatment with anti-fibrosis drug bortezomib restored the levels of miR-21 and Smad7. MiR-21 may function in an amplifying circuit to enhance TGF-β signaling events in SSc fibrosis, and suggesting that miR-21 may act as a potential therapeutic target.

Abstract
OBJECTIVES This paper aims to investigate the efficacy of intravenous immunoglobulin (IVIG) for skin sclerosis in diffuse cutaneous systemic sclerosis (dcSSc) by a randomised, double-blind, placebo-controlled, multicentre trial (DBT) with subsequent long-term observational and readministration studies. METHODS In DBT, IVIG (400mg/kg/day for 5 consecutive days: a single course) or placebo (P) was intravenously administered to 63 dcSSc patients of 17 medical institutions in Japan, and changes in the modified Rodnan skin thickness score (MRSS) 12 weeks after administration or at discontinuation were compared as a primary endpoint. Patients with a 5-point or more improvement in the MRSS were continuously observed (long-term observational study), whereas IVIG was administered to those with less than a 5-point improvement (readministration study). RESULTS In DBT, changes in the MRSS (mean±SD) were -3.3±4.2 and -4.2±4.6 in IVIG and P groups, respectively, and were not significantly different. Non-responder patients were subsequently subjected to the readministration study, and the change in the MRSS (LS-mean±SEM) at 60 weeks after the first administration was -8.3±1.0 in the IVIG → IVIG (GG) group treated with two courses of IVIG administration and -4.1±1.1 in the P → IVIG (PG) group treated with a single course of IVIG administration. The GG group represented a significant improvement in the MRSS against the PG group (p=0.0040). CONCLUSIONS Although the primary endpoint was not achieved in DBT, repeated administration of IVIG for two courses may be effective for skin sclerosis in dcSSc. Further investigation by the administration of plural courses will be necessary.

Abstract
Diffuse systemic sclerosis carries a high morbidity and mortality. The Prospective Registry of Early Systemic Sclerosis (PRESS), a multicentre incident cohort study of patients with early diffuse cutaneous systemic sclerosis, has the goal of advancing the understanding of disease pathogenesis and identifying novel biomarkers. In this review, PRESS investigators discuss the evidence pertaining to the more commonly used treatments for early diffuse SSc skin disease including methotrexate, mycophenolate, cyclophosphamide, azathioprine, and intravenous immunoglobulin. This review highlights the unmet need for effective treatment in early diffuse SSc as well as its more rigorous study. Nonetheless, the PRESS investigators aim to decrease intra- and inter-institutional variability in prescribing in order to improve the understanding of the clinical course of early diffuse SSc skin disease.

Abstract
OBJECTIVES To assess the safety and efficacy of long-term treatment with rituximab (RTX) in patients with systemic sclerosis (SSc). METHODS Eight patients with SSc-associated interstitial lung disease (ILD) received 4 cycles of RTX and had a follow-up of 2 years. Lung involvement was assessed by pulmonary function tests and chest HRCT. Skin involvement was assessed both clinically and histologically. RESULTS We found a linear improvement of lung function and skin thickening over the 2 years of RTX treatment. There was a significant increase of FVC at 2 years compared to baseline (mean ± SEM: 77.13±7.13 vs. 68.13±6.96, respectively, p<0.0001). Similarly, DLco increased significantly at 2 years compared to baseline (mean ± SEM: 63.13±7.65 vs. 52.25±7.32, respectively, p<0.001). Skin thickening, assessed with the MRSS, improved significantly at 2 years compared to baseline (mean ± SEM: 4.87±0.83 vs. 13.5±2.42, respectively, p<0.0001). A reduction in myofibroblast score was seen histologically following RTX treatment. CONCLUSIONS Our results indicate that long-term treatment with RTX may favourably affect lung function and skin fibrosis in patients with SSc. Larger scale, multicentre, randomised, controlled studies are needed to further explore the efficacy of RTX in SSc.

Reactivity of pulmonary circulation and right ventricle function to inhaled nitric oxide in systemic sclerosis patients. Clin Rheumatol 2012; 31:99-104. [PMID: 21670950 PMCID: PMC3249214 DOI: 10.1007/s10067-011-1792-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2010] [Revised: 04/05/2011] [Accepted: 05/31/2011] [Indexed: 12/03/2022]
Abstract
Systemic sclerosis (SSc) is complicated by pulmonary hypertension and right ventricle (RV) failure in approximately 10% of the patients. Factors influencing the reactivity of pulmonary circulation to vasodilators are not established, while the examination of vasoreactivity is important in determining the treatment, because systemic administration of oral vasodilators can induce severe adverse events in nonresponders. The mechanism of RV failure in SSc is unclear and may result either from increased RV afterload or intrinsic myocardial disease. The aim of the study was to assess the reactivity of pulmonary circulation to inhaled nitric oxide (iNO) and to evaluate its influence on RV function in SSc patients with elevated right ventricle systolic pressure (RVSP). In 60 SSc patients aged 24-73 (58 females, two males; 33 patients with limited SSc and 27 with diffuse SSc), echocardiographic examination with tissue Doppler echocardiography (TDE) was performed. RV function was measured by systolic (S) and early diastolic (E) velocity of tricuspid annulus by TDE. In patients with RVSP >45 mmHg, the reactivity of pulmonary circulation was assessed by iNO test. High-resolution computerized tomography (HRCT) was performed to assess the extent of pulmonary fibrosis. Of 14 SSc subjects with elevated RVSP (13 females, one male; RVSP 47-62 mmHg), positive reaction to iNO was observed in five (RVSP decreased from 51.6 ± 3.7 to 32.24 ± 2.3 mmHg); nine patients were not reactive (RVSP 53.5 ± 5.7 mmHg before iNO vs. 49.6 ± 6.7 mmHg). RV systolic function was decreased in patients with elevated RVSP as compared to the patients with normal pulmonary pressure (S velocity 13.2 ± 1.3 vs. 14.4 ± 1.6 cm/s, respectively, p < 0.05). Significant increase of RV systolic function during iNO test was found in reactive patients only (S velocity before iNO 12.8 ± 1.2 cm/s, during iNO 14.5 ± 1.5 cm/s, p < 0.01). RVSP decrease strongly correlated with S velocity increase (r = 0.95, p < 0.0001). Response to iNO was found only in limited form of SSc; diffuse SSc patients showed no response. Pulmonary fibrosis on HRCT was more frequent in subjects nonreactive to iNO (67% of patients) than in the reactive group (40% of patients). The reactivity of pulmonary circulation to iNO in SSc patients with elevated RVSP was found predominantly in limited form of the disease. Pulmonary fibrosis typical for diffuse SSc was more frequent in nonreactive subjects. Elevated pulmonary pressure plays an important role in RV systolic dysfunction. Pulmonary pressure decrease during iNO test leads to the improvement of RV systolic function. Therapy for right-heart failure in reactive SSc patients should be directed, if possible, at the decrease in pulmonary resistance.

Abstract
Pityriasis rubra pilaris (PRP) is a rare, chronic erythematous squamous disorder of unknown etiology. It has been found in association with several autoimmune diseases, including thyroiditis, myositis, myasthenia gravis and vitiligo. Herein we report a case of systemic sclerosis in a patient with classic adult pityriasis rubra pilaris. A 38 year old woman with classic adult type 1 pityriasis rubra pilaris (PRP) developed progressive skin thickening of the trunk, face, upper and lower extremities after 2 years of PRP treatment with topical emollients and steroids. Clinical examination and immunological findings were consistent with SSc. Co-existence of these two rare conditions is documented for the first time.

Abstract
A 31-year-old woman presented with progressive deep linear induration on her lower abdomen, forearms and thighs. These symptoms developed three years after allogenic stem cell transplantation. Furthermore, the patient showed multiple hypopigmented lichenoid papules on the extensor surfaces of the forearms consistent with lichen sclerosus. Histological analysis of a biopsy specimen from her left thigh showed dermal sclerosis extending into the fascia, thus establishing the diagnosis of a rare combination of superficial and deep sclerodermoid chronic graft-versus-host disease. After 7 cycles of extracorporeal photopheresis, a marked resolution of the indurations and a reduction of the modified Rodnan skin score from 12 to 7 were noted.

Abstract
AIMS To evaluate the presence of temporomandibular disorders (TMD) in systemic sclerosis (SSc) patients and its possible association with the severity of skin involvement. METHODS The presence of TMD was evaluated in 35 SSc women and 30 age- and sex-matched healthy controls by means of the anamnestic (A(i)) and clinical (D(i)) Helkimo indices; the jaw mobility was further analyzed (M(I)). Skin involvement was scored by the Modified Rodnan Skin Score (MRSS). RESULTS Signs and symptoms of TMD were more frequent in SSc patients than in controls, the frequency distribution of the different clinical dysfunction indices differing significantly (P < .001) between patients (D(i)0 8.6%, D(i)I 48.6%, D(i)II 22.8%, and D(i)III 20%) and controls (D(i)0 50%, D(i)I 33.3%, and D(i)II 16.7%). Cyclophosphamide for severe and rapidly progressive cutaneous fibrosis was prescribed in six out of seven patients with severe signs (D(i)III), in contrast this treatment was indicated for only two out of 25 patients with mild to moderate signs (D(i)I and D(i)II, P < .001). Impaired jaw mobility was more frequent in SSc patients than controls (P < .001). It was severe in 77.1% (M(I)II) and mild in 22.9% (M(I)I) of the cases, in contrast to controls (M(I)0 33.4%, M(I)I 53.3%, and M(I)II 13.3%; P < .001). Approximately half of SSc patients with severe (M(I)II) but none of those with mild impairment were on cyclophosphamide treatment for severe cutaneous fibrosis (P = .02). CONCLUSION Severe signs of TMD according to the anamnestic and clinical Helkimo indices were very frequent in SSc patients.

Abstract
A case of 70-year-old cachectic female, nonsteroid anti-inflammatory drugs abuser, with progressive systemic sclerosis, who was admitted to our hospital due to joint pain and fatigue is presented. During hospitalisation the patient developed symptoms of acute myocarditis. Angiography of coronary arteries did not reveal narrowing of the vessels. Alimentary supplementation and therapy for heart failure (diuretics, vasodilators, angiotensin-converting enzyme inhibitor and beta-blocker) were used. In repeated echocardiography examinations ejection fraction systematically improved and hemodynamic stabilisation was obtained. Scleroderma, malnutrition, toxicity of nonsteroid anti-inflammatory drugs and infectious agents were considered as a cause of myocarditis.
