Intravenous dexamethasone pulse therapy in diffuse systemic sclerosis. A randomized placebo-controlled study

Role of rituximab in the treatment of systemic sclerosis: A literature review

This literature review aimed to evaluate the effectiveness of rituximab (RTX) in patients with systemic sclerosis (SSc). PubMed was searched for articles, published through 31 March 2022, on any controlled studies using RTX in the treatment of SSc. Of 85 identified articles, 9 were selected by title/abstract screening and full text examination. All nine articles reported outcomes of forced vital capacity (%FVC), and seven reported those of modified Rodnan skin scores (mRSS). The results showed that among the seven controlled studies evaluating skin lesions in patients with SSc, four showed a significant improvement of mRSS by RTX when compared with a control group, whereas three showed no significant effect. Among the nine controlled studies evaluating lung lesions, five showed a significant improvement of %FVC compared with a control group, whereas four showed no significant effect. In conclusion, RTX may be effective in the treatment of skin and lung lesions in patients with SSc. The profiles of SSc patients for whom RTX was indicated were unclear, although patients with diffuse cutaneous SSc and those positive for anti-topoisomerase I antibody were considered potential targets. Additional studies are needed to assess the long-term effectiveness of RTX in the treatment of patients with SSc.

Treatment of systemic sclerosis

Systemic sclerosis (SSc) is a rare connective tissue disease characterized by skin and visceral fibrosis, vascular hyperreactivity and obliterative vasculopathy. Some of its complications such as interstitial lung disease (ILD), pulmonary arterial hypertension (PAH) and heart involvement can be life-threatening and are associated with a high mortality and a poor prognosis. Many clinical trials were carried out in order to improve the survival and prognosis of SSc patients. The management of SSc is based on the frequent and regular assessment of the potential organ damage, and if present, the establishment of graduated pharmacological therapeutic strategies, associated with non-pharmacological procedures. Several randomized clinical trials have showed significant positive outcomes regarding some specific involvements. Many advances have been made, especially in the field of targeted therapies and personalized medicine, based on specific characteristics of the patient and the SSc.

A patient-centered approach to the burden of symptoms in patients with scleroderma treated with Bosentan: A prospective single-center observational study

Systemic sclerosis (SSc) is a rare and complex autoimmune disease associated with poor vital and functional outcomes. The functional hindrance in patients derives from various disease-specific manifestations, including Raynaud's phenomenon and digital ulcers (DUs). Bosentan is an endothelin receptor antagonist capable of preventing the appearance of new DUs in patients with scleroderma. The present study aimed to evaluate the effects of Bosentan on the severity of Raynaud's phenomenon, DU-related symptoms and functional impairment during the first year of treatment. A prospective study that included adult patients with SSc admitted to the Rheumatology Department between January 2016 and January 2017 that were candidates for Bosentan therapy, was performed. All patients were asked to evaluate the burden of symptoms secondary to Raynaud's and DUs using a visual analogue scale (VAS), whereas functional hindrance was assessed via Health Assessment Questionnaire Disability Index (HAQ-DI). The outcomes were assessed at baseline and every 3 months during 1 year of therapy. Among the 41 patients included initially, 2 participants discontinued the treatment after 1 month due to adverse events (elevation of liver enzymes). The study cohort exhibited a significant improvement in HAQ-DI, VAS-R and VAS-DU scores in response to Bosentan therapy over the 1-year follow-up period. Higher scores at baseline predicted a weaker treatment-related improvement, with the risk of a poor outcome being increased by 220% for VAS-R, 116% for VAS-DU, whereas no increase was observed for HAQ-DI. The post-treatment improvement in VAS-DU levels was associated with a better outcome for HAQ-DI (R=0.44; P=0.005). This association was not identified for VAS-R (R=0.24; P=0.137). Throughout the follow-up period, patients with dyspnea presented with significantly higher HAQ-DI scores compared with non-dyspneic patients. Bosentan therapy may indirectly influence functionality and quality of life in patients with scleroderma by reducing the burden of Raynaud's and DU-related symptoms. Nonetheless, patients with SSc with a decreased symptom burden at baseline exhibited improved outcomes.

Therapeutic efficacy of combined glucocorticoid, intravenous cyclophosphamide, and double-filtration plasmapheresis for skin sclerosis in diffuse systemic sclerosis

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.

Skin thickness score as a surrogate marker of organ involvements in systemic sclerosis: a retrospective observational study

Background

Previous studies have shown the relationship between higher skin thickness score and the existence of organ involvements in systemic sclerosis (SSc). Here, we firstly investigated the correlation between skin thickness score and quantitative measurements of each organ involvement in Japanese patients with SSc.

Methods

All Japanese SSc patients hospitalized to our clinic for initial evaluation of SSc were selected. Skin thickness was evaluated by modified Rodnan total skin thickness score (mRSS). Relationship between mRSS and prevalence or incidence of organ involvements was examined by logistic analyses. Correlation between mRSS and quantitative measurements of organ involvements was examined by correlation analyses and regression analyses.

Results

We recruited 198 patients into our study. The mean disease duration was 7.3 years with the mean follow-up duration of 3.2 years. Multivariate logistic regression analyses revealed that higher mRSS is related to higher prevalence of interstitial lung disease (P < 0.05), restrictive impairment (P < 0.01), and diffusion impairment (P < 0.05) of the lung. Correlation analyses revealed mRSS negatively correlates with forced vital capacity (P < 0.001) and diffusing capacity (P < 0.001) of the lung. Correlation between longitudinal change of mRSS and that of forced vital capacity (P < 0.05) or diffusing capacity (P < 0.001) of the lung was also demonstrated.

Conclusions

Skin thickness score significantly correlates with quantitative measurements of lung involvement in Japanese patients with SSc.

Dexamethasone inhibits cytokine production in PBMC from systemic sclerosis patients

Glucocorticoids (GC) are widely used in the treatment of SSc, although there is not much evidence to prove the benefits offered by these drugs in this disease. In this study, we evaluated the effects of a GC on cytokine production in peripheral blood mononuclear cells (PBMC) of SSc patients. The effect of dexamethasone (DEX) was evaluated in PBMC of 21 SSc patients and 10 healthy volunteers after stimulation of cells with anti-CD3 and anti-CD28. Cytokines IL-2, IL-4, IL-6, IL-10, IL-17A, IL-17F, IFN-γ, TNF, and IL-1β were quantified in the culture supernatant by CBA or ELISA. Of the patients evaluated in this study, 8 (38%) were taking corticosteroids, and esophageal dysfunction was more frequent in these patients when compared to those who did not take corticosteroids. DEX (1.000 nM) treatment in PBMC of SSc patients stimulated with anti-CD3 and anti-CD28 promoted a significant reduction in IL-2, IL-4, IL-6, IL-10, IL-17A, IFN-γ, TNF, IL-1β (p < 0.001 for all), and IL-17F (p = 0.023) cytokines levels. We did not observe differences in response to in vitro treatment with DEX between groups of patients taking or not taking corticosteroids. In PBMC from healthy volunteers, we observed that DEX treatment significantly reduced IL-4, IFN-γ (p = 0.003 for both), IL-6, IL-10, IL-17A, and TNF (p = 0.002 for all) cytokines. These results show that DEX treatment in PBMC of SSc patients reduced the production of important cytokines involved in the pathogenesis of the disease, suggesting a possible mechanism of action of the CG in the treatment of SSc.

Inflammatory arthritis in systemic sclerosis: What to do?

Musculoskeletal involvement, including arthritis and tendinopathy, is a common and important determinant of disability and impaired quality of life in systemic sclerosis. However, the treatment of arthritis in systemic sclerosis has not been studied as a primary outcome in randomized controlled trials, and arthritis-specific outcome measures for systemic sclerosis have not been sufficiently validated to date. Rheumatologists caring for patients with systemic sclerosis must address these complaints regularly despite the fact that the level of evidence for the treatment of systemic sclerosis–related inflammatory arthritis is limited. Consensus statements, based on treatments for related musculoskeletal aspects of rheumatoid arthritis, systemic lupus erythematosus, and other autoimmune diseases, support the use of methotrexate and hydroxychloroquine. Newer biologics, which have efficacy in the treatment of other autoimmune conditions, may show promise in the treatment of arthritis in systemic sclerosis. In this article, we review the current literature on the assessment and treatment of systemic sclerosis arthritis in order to address management considerations.

Diagnostic criteria, severity classification and guidelines of systemic sclerosis

Several effective drugs have been identified for the treatment of systemic sclerosis (SSc). However, in advanced cases, not only their effectiveness is reduced but they may be also harmful due to their side-effects. Therefore, early diagnosis and early treatment is most important for the treatment of SSc. We established diagnostic criteria for SSc in 2003 and early diagnostic criteria for SSc in 2011, for the purpose of developing evaluation of each organ in SSc. Moreover, in November 2013, the American College of Rheumatology and the European Rheumatology Association jointly developed new diagnostic criteria for increasing their sensitivity and specificity, so we revised our diagnostic criteria and severity classification of SSc. Furthermore, we have revised the clinical guideline based on the newest evidence. In particular, the clinical guideline was established by clinical questions based on evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guideline easy to use and reliable based on the newest evidence, and to present guidance as specific as possible for various clinical problems in treatment of SSc.

Corticosteroid inhibits chemokines production in systemic sclerosis patients

In this study, we evaluated glucocorticoids (GC) effects on cytokine/chemokine levels in serum samples and peripheral blood mononuclear cell (PBMC) production from systemic sclerosis (SSc) patients. We evaluated cytokine and chemokine levels in serum samples from SSc patients taking or not taking systemic glucocorticoids. PBMCs response to methylprednisolone (MP) was examined from 15 SSc patients and 8 healthy control subjects following PBMC stimulation with anti-CD3/CD28. Cytokine (IFN-γ, TNF, IL-2, IL-4, IL-6, IL-10, and IL-17A) and chemokine (CXCL8/IL-8, CCL5/RANTES, CXCL9/MIG, CCL2/MCP-1, and CXCL10/IP-10) levels were quantified in serum and in PBMC culture supernatants by CBA or ELISA. Compared with patients not taking corticosteroids, we did not observe any significant differences in cytokines/chemokines serum levels in patients using systemic corticosteroids. After stimulation with anti-CD3/CD28, PBMCs treated with MP (100μM), showed a significant reduction of CCL2/MCP-1 (p=0.001), CCL5/RANTES (p=0.04), and CXCL8/IL-8 (p=0.003) levels in SSc patients. In PBMC from healthy controls, we observed decreased IFN-γ, TNF, IL-2, and IL-10 levels after MP treatment, compared with stimulated condition (p<0.01 for all). However in SSc patients, we did not find any significant reduction in these cytokine levels after MP treatment. In conclusion, CCL2/MCP-1, CCL5/RANTES, and CXCL8/IL-8 are chemokines that are potentially modulated by corticosteroids in vitro in SSc patients, but no effect was observed on IL-2, IL-4, IL-6, IL-10, IL-17A, TFN, and IFN-γ secretion. These results suggest a potential effect of GCs on SSc treatment and may reflect the benefit of their use in some patients.

Points to consider for clinical trials of the gastrointestinal tract in systemic sclerosis

The pathogenesis of gastrointestinal tract involvement in SSc is not fully understood. However, gastrointestinal signs and symptoms are very common. Trials to test therapies, with rare exceptions, should be double-blind, randomized trials with either active therapy or placebo as comparators. Trial duration will vary dependent on the anticipated therapy and should usually be 6-24 weeks long, although some motility trials may need to be 52 weeks. As in any well-controlled trial, inclusion and exclusion criteria should encourage relatively uniform patients with sufficiently active disease to discern response, importantly considering disease duration. Previous therapy, co-morbid conditions, potentially confounding and/or concomitant therapy should be considered. Outcome measures should include both objective/semi-objective and subjective measures, although validated measures are not frequent and design needs to consider using only validated measures. Unvalidated measures can be included to validate them for future use. A full analysis plan should be completed before study commencement, including the method to account for missing data.

The matrix protein Fibulin-5 is at the interface of tissue stiffness and inflammation in fibrosis

Fibrosis is a pervasive disease in which the excessive deposition of extracellular matrix (ECM) compromises tissue function. Although the underlying mechanisms are mostly unknown, matrix stiffness is increasingly appreciated as a contributor to fibrosis rather than merely a manifestation of the disease. Here we show that the loss of Fibulin-5, an elastic fibre component, not only decreases tissue stiffness, but also diminishes the inflammatory response and abrogates the fibrotic phenotype in a mouse model of cutaneous fibrosis. Increasing matrix stiffness raises the inflammatory response above a threshold level, independent of TGF-β, to stimulate further ECM secretion from fibroblasts and advance the progression of fibrosis. These results suggest that Fibulin-5 may be a therapeutic target to short-circuit this profibrotic feedback loop.

Systemic sclerosis: current concepts in pathogenesis and therapeutic aspects of dermatological manifestations

Systemic sclerosis (SSc) is a chronic, multisystem connective tissue disease with protean clinical manifestations. Recent advances in understanding the pathogenic mechanisms have led to development of target-oriented and vasomodulatory drugs which play a pivotal role in treating various dermatological manifestations. An exhaustive literature search was done using Medline, Embase, and Cochrane library to review the recent concepts regarding pathogenesis and evidence-based treatment of salient dermatological manifestations. The concept of shared genetic risk factors for the development of autoimmune diseases is seen in SSc. It is divided into fibroproliferative and inflammatory groups based on genome-wide molecular profiling. Genetic, infectious, and environmental factors play a key role; vascular injury, fibrosis, and immune activation are the chief pathogenic factors. Vitamin D deficiency has been documented in SSc and correlates with the severity of skin involvement. Skin sclerosis, Raynaud's phenomenon (RP) with digital vasculopathies, pigmentation, calcinosis, and leg ulcers affect the patient's quality of life. Immunosuppressives, biologicals, and hematopoietic stem cell transplantation are efficacious in skin sclerosis. Endothelin A receptor antagonists, calcium-channel blockers, angiotensin receptor inhibitors, prostacyclin analogs, and phosphodiesterase type 5 (PDE-5) inhibitors are the mainstay in RP and digital vasculopathies. Pigmentation in SSc has been attributed to melanogenic potential of endothelin-1 (ET-1); the role of ET 1 antagonists and vitamin D analogs needs to be investigated. Sexual dysfunction in both male and female patients has been attributed to vasculopathy and fibrosis, wherein PDE-5 inhibitors are found to be useful. The future concepts of treating SSc may be based on the gene expression signature.

EULAR evidence-based and consensus-based recommendations on the management of medium to high-dose glucocorticoid therapy in rheumatic diseases

To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key clinical topics concerning the safe use of medium to high-dose GCs. The final recommendations were selected via a Delphi consensus approach. A systematic literature search of PubMed, EMBASE and Cochrane Library was used to identify evidence concerning each of the propositions. The strength of recommendation was given according to research evidence, clinical expertise and patient preference. The 10 propositions regarded patient education and informing general practitioners, preventive measures for osteoporosis, optimal GC starting dosages, risk-benefit ratio of GC treatment, GC sparing therapy, screening for comorbidity, and monitoring for adverse effects. In general, evidence supporting the recommendations proved to be surprisingly weak. One of the recommendations was rejected, because of conflicting literature data. Nine final recommendations for the management of medium to high-dose systemic GC therapy in rheumatic diseases were selected and evaluated with their strengths of recommendations. Robust evidence was often lacking; a research agenda was created.

Pulse steroid therapy

Intravenous supra-pharmacological doses of corticosteroids are used in various inflammatory and autoimmune conditions because they are cumulatively less toxic than sustained steroid treatment at lower quantitative dosage. Their action is supposed to be mediated through non-genomic actions within the cell. Common indications for use in children include steroid resistant and steroid dependent nephrotic syndrome, rapidly progressive glomerulonephritis, systemic vasculitis, systemic lupus erythematosus, acute renal allograft rejection, juvenile rheumatoid arthritis, juvenile dermatomyositis, pemphigus, optic neuritis, multiple sclerosis and acute disseminated encephalomyelitis. Methylprednisolone and dexamethasone show similar efficacy in most conditions. Therapy is associated with significant side effects including worsening of hypertension, infections, dyselectrolytemia and behavioral effects. Adequate monitoring is essential during usage.

Assessment of unmet needs and the lack of generalizability in the design of randomized controlled trials for scleroderma treatment

OBJECTIVE

To determine the generalizability of randomized controlled trials (RCTs) in the treatment of systemic sclerosis (SSc) using the Canadian Scleroderma Research Group (CSRG) database.

METHODS

We identified articles related to SSc published from 1958 to 2006. Key points on trial design were recorded. The inclusion/exclusion criteria were used in conjunction with the CSRG database to determine the proportion of patients with SSc who would theoretically be eligible for these trials. Articles were classified into subcategories according to the target system. The CSRG database contains 438 patients with SSc from 14 Canadian centers. Results were in median (%) and mean (%) with 95% confidence intervals (95% CIs).

RESULTS

In total, 210 articles were evaluated and 73 were selected for inclusion in this study. The mean percentage of eligible patients with SSc associated with other conditions was 35% (95% CI 17-53) for Raynaud's phenomenon, 24% (95% CI 1-47) for digital ulcers, 48% (95% CI 27-68) for gastrointestinal (GI) involvement, 32% (95% CI 20-43) for overall disease modification, 6% (95% CI 4-8) for pulmonary arterial hypertension, 2% (95% CI 0-4) for interstitial lung disease, and 38% (95% CI 12-64) for other categories.

CONCLUSION

Except for GI trials, <38% of the identified patients with SSc would have been suitable to enter the RCTs. Although some patients would be ineligible because they lack certain organ involvement, RCTs designed to include appropriate patients with SSc are needed; there are few proven treatments and trials typically do not include the majority of those who could potentially benefit from the intervention.

Intravenous dexamethasone vs methylprednisolone pulse therapy in the treatment of acute endothelial graft rejection

PURPOSE

To study the outcome of therapy for acute endothelial graft rejection with an intravenous (i.v.) pulse of dexamethasone vs methylprednisolone, in addition to topical corticosteroids.

METHODS

Records of 98 eyes of 99 patients treated for endothelial graft rejection with a single i.v. pulse of dexamethasone or methylprednisolone in addition to topical steroids, between January 1999 and June 2004, were retrospectively reviewed. Baseline characteristics such as surgery-rejection interval, time taken to consult after onset of symptoms, history of failed grafts, extent of stromal vascularization, best-corrected visual acuity (BCVA) and corneal thickness at the time of presentation were noted. Main outcome measures following treatment for rejection included improvement in BCVA, change in corneal thickness, and reversal of graft rejection.

RESULTS

Fifty-one patients were treated with i.v. methylprednisolone and 47 with i.v. dexamethasone, in addition to topical steroids. Both groups were found to be comparable with respect to baseline parameters, that is, time taken to present, history of failed grafts, extent of stromal vascularization, BCVA, and graft thickness. Graft rejection could be successfully reversed in 72.3% cases in the dexamethasone group and 49% in the methylprednisolone group (P=0.018). A significant improvement in visual acuity was recorded following treatment in both groups, with a better outcome in the dexamethasone group (P=0.012). Post-treatment pachymetry values were lower than pretreatment values in both groups, with significantly lower final pachymetry in the dexamethasone group (P=0.017). No adverse effects were observed.

CONCLUSION

I.v. pulse therapy with dexamethasone may be used as an effective alternative to methylprednisolone in reversing acute endothelial graft rejection.

Current drug therapy for scleroderma and secondary Raynaud's phenomenon: evidence-based review

(1) Scleroderma and secondary Raynaud's phenomenon are frequently associated with increased morbidity for which no specific standardised treatment guidelines exist. (2) Current therapies for scleroderma target the immune system, with the goal of reducing inflammation and secondary tissue injury and fibrosis. Therapy targeting underlying vascular disease is designed to improve the symptoms of Raynaud's phenomenon and to reduce ischemic injury to involved organs. (3) Few controlled trials of therapy used for scleroderma are completed, and current treatments are largely based on organ-specific therapy and uncontrolled case series suggesting disease modification. (4) Recent randomised, controlled trials in scleroderma demonstrate promising results in the treatment of interstitial lung disease with cyclophosphamide, and vascular disease of the lungs and digits with endothelin receptor antagonists, the phosphodiesterase inhibitor sildenafil and prostacyclins, while trials with methotrexate show only modest benefit in controlling scleroderma-associated skin disease. (5) Prostacyclins are a therapeutic option in patients with secondary Raynaud's phenomenon. Modest benefits have also been shown with alpha1-antagonists and calcium channel blockers, while the effect of ACE inhibitors has been variable. Some data suggest some benefits to the use of the phosphodiesterase inhibitor sildenafil, the serotonin uptake inhibitor fluoxetine and the angiotensin receptor inhibitor losartan.

Design and quality considerations for randomized controlled trials in systemic sclerosis

OBJECTIVE

To appraise systematically randomized controlled trials (RCTs) on systemic sclerosis (SSc) in order to determine whether the parameter of study design and its quality may influence the reporting of efficacy for tested interventions.

METHODS

Seventy RCTs were analyzed (1965-2000) in terms of design, patient characteristics, outcomes, and reported results.

RESULTS

Median sample size was 28 patients. Fifty-nine trials were double blind, but only 16 mentioned the randomization mode and only 7 described allocation concealment. There was sufficient information on withdrawals in 37 trials. Larger trials with longer followup scored higher on quality characteristics, but had higher withdrawal rates. Only 8 trials had a followup of more than 1 year. Significant efficacy was less likely to be reported in double-blind studies (P = 0.029) and in studies with larger rates of withdrawal (P = 0.032). Specification of the following parameters improved over time: power calculations (P = 0.0003), outcomes (P = 0.001), and sample size per arm (P = 0.011).

CONCLUSIONS

Several aspects of the quality of design and conduct of SSc RCTs can be improved. Adequately powered trials with longer followup and clear outcomes are needed.

Pulse glucocorticoids

High-dose intravenous (i.v.) methylprednisolone has been used therapeutically in a number of medical fields to avoid the complications and side effects of long-term glucocorticoid (GC) therapy and because of the perception that high-dose i.v. methylprednisolone may have "special" therapeutic effects. It is possible that aggressive early therapy with GCs allows for a more rapid taper of GCs and therefore prevents some of the dose-related side effects associated with long-term use. Some of the neurologic and rheumatologic literature related to multiple sclerosis and lupus nephritis suggest that i.v. methylprednisolone has therapeutic effects that are different from those of conventional doses of oral prednisone. There is still considerable debate about this in nondermatologic fields, and extrapolation of the role of pulse i.v. methylprednisolone to dermatologic disease, where trials are lacking, is difficult. Given this subset of possible candidates of this therapy as suggested by anecdotal reports, there is at least a rationale for considering the use of this modality in a subset of patients.

Treatment of systemic sclerosis

Guidelines for the conduct of clinical trials in progressive systemic sclerosis have been recommended to determine drug efficacy better. To date, the results of disease-modifying drugs in scleroderma have been disappointing. The treatment of esophagitis has been revolutionized by omeprazole. Raynaud's phenomenon can be treated with calcium channel blockers and iloprost. Scleroderma renal crisis can be treated with aggressive blood pressure control using angiotensin converting enzyme inhibitors. The best treatment for rapidly progressive scleroderma lung is still unknown. Future treatments in scleroderma should be tested with the use of recommended guidelines.
