Effect of Corticosteroid-Sparing Treatment With Mycophenolate Mofetil vs Methotrexate on Inflammation in Patients With Uveitis: A Randomized Clinical Trial

Comparison of CD4 Counts with Mycophenolate Mofetil versus Methotrexate from the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial

PURPOSE

Sub-analysis of the FAST Trial comparing change in CD4 (∆CD4) from baseline through 12 months in uveitis patients treated with mycophenolate mofetil (MMF) and methotrexate (MTX).

METHODS

Patients were randomly allocated to 1.5 g twice daily MMF or 25 mg weekly MTX. Individuals with CD4 counts at baseline, 6 months (or treatment failure prior), and 12 months (or treatment failure between 6 and 12 months) were included. The association between treatment and ∆CD4 (cells/μL) was analyzed using multivariable linear regression.

RESULTS

There was no significant difference in ∆CD4 between MMF and MTX at 6 months (-31.7 cells/μL for MMF compared to MTX; 95% CI: -358.2 to 294.8, P = .85) and 12 months (-78.3 cells/μL for MMF compared to MTX; 95% CI: -468.0 to 311.3; P = .69).

CONCLUSION

There was no significant difference in ∆CD4 between MMF and MTX from baseline to 12 months, suggesting that MMF does not confer additional risk of CD4 lymphopenia in uveitic patients.ClinicalTrials.gov Identifier: NCT01829295.

Methotrexate Effectively Controls Ocular Inflammation in Japanese Patients With Non-infectious Uveitis

This single-center retrospective study investigated the clinical characteristics and efficacy of methotrexate (MTX) for the treatment of non-infectious uveitis for more than 6 months at Hiroshima University, from February 2016 to May 2021. Outcome variables included changes in systemic immunosuppressive treatment and intraocular inflammation. Out of 448 patients with non-infectious uveitis, 35 patients (14 male patients and 21 female patients; 65 eyes) treated with MTX for more than 6 months were analyzed. There were 15 patients with anterior uveitis and 20 with posterior and panuveitis. The mean dose of systemic corticosteroids decreased from 12.1 mg/day at baseline to 1.3 mg/day at 6 months and 0.6 mg at 12 months after starting MTX, and approximately 90% of patients were corticosteroid-free at 12 months. The percentage of eyes with inactive uveitis at 6, 12, and 24 months was 49.2%, 59.6%, and 90.0%, respectively. Mean relapse rate score also significantly decreased from 2.88 at baseline to 0.85 at 12 months (p < 0.001). Inflammatory control was achieved with MTX doses of 8-16 mg/week, with a median dose of 12 mg/week. Adverse effects of MTX were observed in 34.3% of patients, and 11.4% required discontinuation; most commonly hepatotoxicity (58.3%), followed by fatigue (25.0%), and hair loss (16.7%). No significant differences were found between the survival curves of patients with anterior uveitis and posterior/panuveitis (Wilcoxon rank-sum test). The percentage of eyes without IOP-lowering eye drops was significantly higher in patients with posterior/panuveitis at 24 months (p = 0.001). Our study suggests that MTX is effective in controlling ocular inflammation for Japanese patients with non-infectious uveitis. Relatively high incidence of MTX-related adverse effects in the Japanese population indicates that careful monitoring and dose adjustments are crucial for the long-term use of this therapy.

Efficacy and Safety of Immunosuppressant Therapy for Noninfectious Uveitis: A Systematic Review and Meta-Analysis

Objective

To analyze efficacy and safety of immunosuppressant therapy for noninfectious uveitis.

Methods

A network search of PubMed, ResearchGate, and EMBASE databases was conducted for relative literature and studies from the inception of each database to April 2021. Primary outcomes were efficacy and time to treatment failure of immunosuppressant for noninfectious uveitis. Secondary outcome was incidence of adverse events (AEs). Cochrane risk of bias tool was used to assess risk of bias of included studies. Fixed effects model or random effects model was implemented to assess statistical heterogeneity. Subgroup analysis was employed to analyze heterogeneous sources.

Results

Eight studies were deemed eligible for inclusion with a total of 848 patients. Six studies were randomized controlled trials (RCTs). Among them, a single-blind RCT had relatively high measurement bias and performance bias. Immunosuppressant presented favorable efficacy for noninfectious uveitis than placebo, and RR was 1.43 (95% CI: 1.12-1.82). Immunosuppressant for noninfectious uveitis prolonged the time before failure, and HR was 0.43 (95% CI: 0.32-0.54). AEs increased after immunosuppressant was applied. Compared with immunosuppressant, RR of AEs with placebo was 0.88 (95% CI: 0.71-1.08).

Conclusion

Immunosuppressant contributed to controlling progression of noninfectious uveitis to some extent. Compared with placebo, it increased incidence of AEs. More studies with low heterogeneity are warranted for stronger evidence in clinical.

A Review of Ocular Drug Delivery Platforms and Drugs for Infectious and Noninfectious Uveitis: The Past, Present, and Future

Uveitis refers to a broad group of inflammatory disorders of the eye that often require medical and surgical management to improve or stabilize vision and prevent vision-threatening pathological changes to the eye. Drug delivery to the eye to combat inflammation and subsequent complications from uveitic conditions is complex as there are multiple barriers to absorption limiting availability of the needed drug in the affected tissues. As such, there has been substantial interest in developing new drugs and drug delivery platforms to help reduce intraocular inflammation and its complications. In this review, we discuss the challenges of drug delivery, novel technologies recently approved for uveitis patient care and promising drug delivery platforms for uveitis and sequelae of ocular inflammation.

Noninfectious Intermediate, Posterior, or Panuveitis: Results from the Retrospective, Observational, International EyeCOPE Study

Introduction

The EyeCOPE study characterized noninfectious intermediate posterior, or panuveitis (NIIPPU) before biologic agents were widely available.

Methods

This retrospective, observational study included adults with NIIPPU attending a routine ophthalmological visit. Data were collected from the study visit and medical records.

Results

Of 565 patients, 58.8% were female, and the mean age was 41.3 years; 33.8% had idiopathic uveitis and 45.8% had panuveitis. The median time from symptom onset to diagnosis and treatment was 27.0 and 30.5 days, respectively. Patients received immunosuppressants and systemic/local corticosteroids. Most patients experienced substantial decline in ocular function (mean best corrected visual acuity, 0.4 logMAR). Mean total work productivity impairment among employed patients was 31.0%. Most patients reported ocular complications (70.8%) such as vision loss and cataracts.

Conclusions

Despite treatment, most patients with NIIPPU experienced a decline in ocular function and ocular complications. There is an unmet need for additional NIIPPU treatment, such as targeted monoclonal antibodies.

Society for Immunotherapy of Cancer (SITC) clinical practice guideline on immune checkpoint inhibitor-related adverse events

Immune checkpoint inhibitors (ICIs) are the standard of care for the treatment of several cancers. While these immunotherapies have improved patient outcomes in many clinical settings, they bring accompanying risks of toxicity, specifically immune-related adverse events (irAEs). There is a need for clear, effective guidelines for the management of irAEs during ICI treatment, motivating the Society for Immunotherapy of Cancer (SITC) to convene an expert panel to develop a clinical practice guideline. The panel discussed the recognition and management of single and combination ICI irAEs and ultimately developed evidence- and consensus-based recommendations to assist medical professionals in clinical decision-making and to improve outcomes for patients.

Inflammation in neurocysticercosis: clinical relevance and impact on treatment decisions

INTRODUCTION

Neurocysticercosis is caused by the localization of Taenia solium larvae in the central nervous system. The disease remains endemic in most countries of Latin America, Asia and Africa. While major improvements have been made in its diagnosis and treatment, uncertainties persist regarding the clinical implications and treatment of the inflammatory reaction associated with the disease.

AREAS COVERED

In this review, based on PubMed searches, the authors describe the characteristics of the immune-inflammatory response in patients with neurocysticercosis, its clinical implications and the treatment currently administered. The dual role of inflammation (participating in both, the death of the parasite, and the precipitation of serious complications) is discussed. New therapeutic strategies of potential interest are presented.

EXPERT OPINION

Inflammatory reaction is the main pathogenic mechanism associated to neurocysticercosis. Its management is mainly based on corticosteroids administration. This strategy had improved prognostic of patients as it allows for the control of most of the inflammatory complications. On the other side, it might be involved in the persistence of parasites in some patients, despite cysticidal treatment, due to its immunosuppressive properties. New strategies are needed to improve therapeutical management, particularly in the severest presentations.

Clinical features, visual outcome, and poor prognostic factors in occlusive retinal vasculitis

OBJECTIVE

To investigate the clinical features, treatment, and visual outcome of occlusive retinal vasculitis (ORV), with a focal analysis on prognostic factors associated with poor visual outcome.

METHODS

We conducted a retrospective cohort study in patients diagnosed with ORV with at least 6 months of follow-up. Demographic data, ocular features, best corrected visual acuity (BCVA), fluorescein angiography, therapy regimens, and outcomes were collected from the Massachusetts Eye Research and Surgery Institution database from 2006 to 2017. Multivariate logistic regression was performed to analyze the factors independently predicting poor visual outcome.

RESULTS

Fifty-two patients (69 eyes) were enrolled, 42 with noninfectious cause, 9 with infectious cause, and 1 with masquerade uveitis. Systemic inflammatory diseases, including necrotizing vasculitis, sarcoidosis, multiple sclerosis, systemic lupus erythematosus, and Behçet's disease comprised the causes of ORV. Forty of the 42 patients with noninfectious ORV received immunomodulatory therapy (IMT), and 35 patients (87.5%) were able to achieve steroid-free remission. Compared with the BCVA at the initial visit (0.66 [±0.11] logMAR), there was significant improvement at the most recent visit (0.37 [±0.07] logMAR, p = 0.001). A multivariate analysis demonstrated that optic nerve atrophy, macular ischemia, and poor BCVA at initial presentation were independently correlated with poor visual outcome.

CONCLUSIONS

ORV could be caused by a wide spectrum of systemic inflammatory diseases. Aggressive IMT is preferred to achieve a steroid-free durable remission for noninfectious ORV. Optic nerve atrophy, macular ischemia, and poor BCVA at the initial visit predict a poor visual outcome.

Health- and Vision-Related Quality of Life in a Randomized Controlled Trial Comparing Methotrexate and Mycophenolate Mofetil for Uveitis

PURPOSE

To evaluate changes in health-related and vision-related quality of life (VRQoL) among patients with noninfectious uveitis who were treated with antimetabolites.

DESIGN

Secondary analysis of a randomized controlled trial.

PARTICIPANTS

Patients with noninfectious uveitis from India, the United States, Australia, Saudi Arabia, and Mexico.

METHODS

From 2013 through 2017, 216 participants were randomized to receive 25 mg weekly oral methotrexate or 1.5 g twice daily oral mycophenolate mofetil. Median changes in quality of life (QoL) were measured using Wilcoxon signed-rank tests, and differences between treatment groups were measured using linear mixed models, adjusting for baseline QoL score, age, gender, and site. Among Indian patients, VRQoL scores from a general scale (the National Eye Institute Visual Function Questionnaire [NEI-VFQ]) and a culturally specific scale (the Indian Visual Function Questionnaire [IND-VFQ]) were compared using Pearson correlation tests.

MAIN OUTCOME MEASURES

Vision-related QoL (NEI-VFQ and IND-VFQ) and health-related QoL (HRQoL; physical component score [PCS] and mental component score [MCS] of the Medical Outcomes Study 36-Item Short Form Survey [SF-36v2]) were measured at baseline, the primary end point (6 months or treatment failure before 6 months), and the secondary end point (12 months or treatment failure between 6 and 12 months).

RESULTS

Among 193 participants who reached the primary end point, VRQoL increased from baseline by a median of 12.0 points (interquartile range [IQR], 1.0-26.1, NEI-VFQ scale), physical HRQoL increased by a median of 3.6 points (IQR, -1.4 to 14.9, PCS SF-36v2), and mental HRQoL increased by a median of 3.0 points (IQR, -3.7 to 11.9, MCS SF-36v2). These improvements in NEI-VFQ, SF-36v2 PCS, and SF-36v2 MCS scores all were significant (P < 0.01). The linear mixed models showed that QoL did not differ between treatment groups for each QoL assessment (NEI-VFQ, IND-VFQ, PCS SF-36v2, and MCS SF-36v2; P > 0.05 for all). The NEI-VFQ and IND-VFQ scores for Indian participants were correlated highly at baseline and the primary and secondary end points (correlation coefficients, 0.87, 0.80, and 0.90, respectively).

CONCLUSIONS

Among patients treated with methotrexate or mycophenolate mofetil for uveitis, VRQoL and HRQoL improved significantly over the course of 1 year and did not differ by treatment allocation. These findings suggest that antimetabolites could improve overall patient well-being and daily functioning.

Multidisciplinary management of auto-immune ocular diseases in adult patients by ophthalmologists and rheumatologists

Purpose

Management of chronic vision threatening auto‐immune ocular diseases (AIOD, e.g. uveitis, scleritis) can be challenging. Guidelines recommend a multidisciplinary approach (MDA) with ophthalmologists and rheumatologists, to enhance the recognition of systemic diseases and guide the use of immunosuppressives. However, the indications and results of such an approach have not yet been studied.

Methods

A monocentre, retrospective chart review of all patients treated in a MDA between ophthalmologists and rheumatologists, in a Dutch tertiary center. The collaboration was twofold: a combined multidisciplinary team meeting every 2 weeks, and an ophthalmology‐dedicated rheumatology outpatient clinic. Primary endpoints of this descriptive study were as follows: indications for MDA, new diagnoses of systemic auto‐immune diseases and changes in systemic immunosuppression and prednisone dosages.

Results

In total, 157 adults (mean age 46 years, 57% female, median disease duration 19 months) were included, mainly with uveitis (74%) and scleritis (12%). Multidisciplinary approach (MDA)‐indications included diagnostic workup (32%), treatment support (44%), diagnostic‐and‐treatment support (10%) and side effects (8%). A systemic disease was newly diagnosed in eight and already present in 34 patients. At baseline, 54 patients used oral prednisone at >7.5 mg/day. Non‐corticoid immunosuppressives, mostly methotrexate, were started in 41% of the patients. During follow‐up, systemic prednisone was lowered to ≤7.5 mg/day in 68% of the patients.

Conclusion

This evaluation of an MDA‐programme in the management of AIOD demonstrated its added value. Mainly, it addressed the high demand for support in managing systemic immunosuppression, resulting in significant corticosteroid tapering. In addition, it resulted in the recognition of underlying systemic diseases.

Clinicomolecular Identification of Conserved and Individualized Features of Granulomatous Uveitis

Objective

To identify molecular features that distinguish individuals with shared clinical features of granulomatous uveitis.

Design

Cross-sectional, observational study.

Participants

Four eyes from patients with active granulomatous uveitis.

Methods

We performed single-cell RNA-sequencing with antigen-receptor sequence analysis to obtain an unbiased gene expression survey of ocular immune cells and identify clonally expanded lymphocytes.

Main Outcomes Measures

For each inflamed eye, we measured the proportion of distinct immune cell types, the amount of B or T cell clonal expansion, and the transcriptional profile of T and B cells.

Results

Each individual had robust clonal expansion arising from a single T or B cell lineage, suggesting distinct, antigen-driven pathogenic processes in each patient. This variability in clonal expansion was mirrored by individual variability in CD4 T cell populations, whereas ocular CD8 T cells and B cells were more transcriptionally similar between patients. Finally, ocular B cells displayed evidence of class-switching and plasmablast differentiation within the ocular microenvironment, providing additional support for antigen-driven immune responses in granulomatous uveitis.

Conclusions

Collectively, our study identified both conserved and individualized features of granulomatous uveitis, illuminating parallel pathophysiologic mechanisms, and suggesting that future personalized therapeutic approaches may be warranted.

Laser-Activated Drug Implant for Controlled Release to the Posterior Segment of the Eye

To treat chronic posterior eye diseases, frequent intravitreal injections or sustained-release drug implants are the current standard of care. Sustained-release drug implants often involve burst release of the drugs and the dosage from the implants cannot be controlled after implantation, which may lead to local side effects. The present study attempts to develop a dosage-controllable drug delivery implant that consists of a nanoporous biodegradable PLGA capsule and light-activated liposomes. Controllable drug release from the implant was achieved using a pulsed near-infrared (NIR) laser both in vitro and in vivo. The in vitro drug release kinetics from two different initial dose implants, 1000 and 500 μg, was analyzed by fitting zero-order and first-order kinetics, as well as the Korsmeyer-Peppas and Higuchi models. The 1000 and 500 μg implants fit the first-order and zero-order kinetics model, respectively, the best. The multiple drug releases in the vitreous were determined by an in vivo fluorimeter, which was consistent with the in vitro data. The dose released was also clinically relevant. Histology and optical and ultrasound imaging data showed no abnormality in the eyes received implant treatment, suggesting that the drug delivery system was safe to the retina. This on-demand dose-controllable drug delivery system could be potentially used for long-term posterior eye disease treatment to avoid frequent invasive injections.

Uveitis for the non-ophthalmologist

The uveitides are a heterogeneous group of diseases characterized by inflammation inside the eye. The uveitides are classified as infectious or non-infectious. The non-infectious uveitides, which are presumed to be immune mediated, can be further divided into those that are associated with a known systemic disease and those that are eye limited,-ie, not associated with a systemic disease. The ophthalmologist identifies the specific uveitic entity by medical history, clinical examination, and ocular imaging, as well as supplemental laboratory testing, if indicated. Treatment of the infectious uveitides is tailored to the particular infectious organism and may include regional and/or systemic medication. First line treatment for non-infectious uveitides is corticosteroids that can be administered topically, as regional injections or surgical implants, or systemically. Systemic immunosuppressive therapy is used in patients with severe disease who cannot tolerate corticosteroids, require chronic corticosteroids at >7.5 mg/day prednisone, or in whom the disease is known to respond better to immunosuppression. Management of many of these diseases is optimized by coordination between the ophthalmologist and rheumatologist or internist.

Tregs in Autoimmune Uveitis

Uveitis is a chronic disease with relapsing and remitting ocular attack, which requires corticosteroids and systemic immunosuppression to prevent severe vision loss. Classically, uveitis is referred to an autoimmune disease, mediated by pro-inflammatory Th17 cells and immunosuppressive CD4+CD25+FoxP3+ T-regulatory cells (Tregs). More and more evidence indicates that Tregs are involved in development, resolution, and remission of uveitis. Clinically, many researchers have conducted quantitative and functional analyses of peripheral blood from patients with different subtypes of uveitis, in an attempt to find the changing rules of Tregs. Consistently, using the experimental autoimmune uveitis (EAU) model, researchers have explored the development and resolution mechanism of uveitis in many aspects. In addition, many drug and Tregs therapy investigations have yielded encouraging results. In this chapter, we introduced the current understanding of Tregs, summarized the clinical changes in the number and function of patients with uveitis and the immune mechanism of Tregs involved in EAU model, as well as discussed the progress and shortcomings of Tregs-related drug therapy and Tregs therapy. Although the exact mechanism of Tregs-mediated uveitis protection remains to be elucidated, the strategy of Tregs regulation may provide a specific and meaningful way for the prevention and treatment of uveitis.

Current Approach for the Diagnosis and Management of Noninfective Scleritis

ABSTRACT

Scleritis is a rare, vision-threatening inflammation of the sclera that is often associated with life-threatening systemic illnesses. Rheumatoid arthritis remains the most common associated systemic rheumatic disease and the commonest systemic association of scleritis. Granulomatosis with polyangiitis is the most common cause of vasculitis-associated scleritis. The etiopathogenesis of scleritis remains unclear, but can be immune complex-mediated or due to a local delayed hypersensitivity reaction. Scleritis can involve either the anterior or posterior sclera, and has a wide spectrum of clinical presentations. Among the subtypes of scleritis, necrotizing scleritis has an increased risk of complications and is more commonly associated with anterior uveitis and peripheral ulcerative keratitis. Posterior scleritis is often not diagnosed or missed due to its subtle clinical signs and protean manifestations. Meticulous history taking, detailed ocular examination, and a targeted array of investigations with a multi-disciplinary approach to find any underlying systemic disease are crucial for the management of a case of scleritis. Corticosteroids remain the mainstay of short-term treatment of scleritis; mild to moderate scleral inflammation may respond well to treatment with nonsteroidal antiinflammatory drug or topical corticosteroid. Corticosteroid-sparing immunosuppressive therapies are useful in cases with an inadequate response or failure to provide long-term control of inflammation, and to prevent recurrence of scleritis. Biologic agents are increasingly used in the management of scleritis, not responding to the conventional therapies. This review provides an overview of the various subtypes of scleritis and its systemic associations and evaluates current trends in the diagnosis and management of noninfective scleritis.

Behçet's disease uveitis: is there a need for new emerging drugs?

Introduction: Behçet's disease uveitis (BDU) is a potentially blinding disorder. Systemic treatment with disease-modifying anti-rheumatic drugs (DMARDs) is mandatory in patients with intraocular inflammation involving the posterior segment of the eye. Areas covered: This article discusses existing systemic treatment with corticosteroids and conventional and biologic DMARDs as well as adjunctive local therapy in BDU. An overview is provided for a wide range of biologic DMARDs that have shown promise or investigated in clinical trials. Most recently introduced biologic DMARDs and targeted synthetic DMARDs are also reviewed for their potential in the treatment of BDU. Expert opinion: The prognosis of patients with BDU has remarkably improved after the introduction of biologic DMARDs. An expanding therapeutic armamentarium will allow treatment of most refractory cases. The ultimate goal is to provide drug-free remission with preservation of 20/20 vision.

Paediatric autoimmune and autoinflammatory conditions associated with uveitis

Childhood uveitis comprises a collection of heterogenous ocular phenotypes which are associated with a diverse range of childhood autoimmune and autoinflammatory disorders. Of these genetic and/or acquired disorders, juvenile idiopathic arthritis is the most common, affecting 30-80% of children with uveitis. Up to a third of children with uveitis have 'isolated' idiopathic disease and do not have an associated systemic disease which manifests in childhood. However, uveitis may be the presenting manifestation of disease; thus, the apparently well child who presents with uveitis may have isolated idiopathic disease, but they may have an evolving systemic disorder. The diagnosis of most of the associated disorders is reliant on clinical features rather than serological or genetic investigations, necessitating detailed medical history taking and systemic examination. Adequate control of inflammation is key to good visual outcomes, and multidisciplinary care is key to good broader health outcomes.

An update on the diagnosis and management of ocular sarcoidosis

PURPOSE OF REVIEW

Ocular sarcoidosis is one of the most common causes of uveitis worldwide. The diagnosis and treatment of patients with ocular sarcoidosis remains challenging in some cases. It is important for clinicians to keep up to date with new diagnostic and treatment tools for this disease.

RECENT FINDINGS

The International Workshop on Ocular Sarcoidosis diagnostic criteria were first proposed in 2009 and revised in 2017. The new criteria contained two parts: ocular presentation and systemic investigation. The diagnostic value of liver enzymes was reduced in the new criteria, whereas the value placed of lymphopenia and the CD4/CD8 ratio in bronchoalveolar lavage fluid were increased. Despite not being included in the criteria, recent studies have also highlighted the diagnostic value of serum soluble interleukin-2 receptors. Recent ophthalmologic imaging also provides useful insights for the differential diagnosis.Many new treatments for ocular sarcoidosis have been developed in recent years. The introduction of biological immunomodulatory agents for uveitis treatment represents a big improvement. Antitumor necrosis factor-alpha antibodies, including adalimumab, have been proven to be effective for treating ocular sarcoidosis. Many studies have also suggested that other biological agents could be effective and well tolerated. Newer intravitreal dexamethasone and fluocinolone implants have been developed. Patients treated with these implants have experienced good and sustained control of their intraocular inflammation.

SUMMARY

Diagnosis and treatment options for ocular sarcoidosis have changed over time. However, challenges still exist in some difficult patients. Future studies should focus on finding more sensitive biomarkers and developing more effective immunomodulatory treatments with longer efficacy and less side effects.

Update on the Systemic Treatment of Pediatric Localized Scleroderma

Juvenile localized scleroderma (jLS) is an orphan disease that can lead to cosmetic disfiguration and orthopedic problems. Two recent publications review the current recommendations regarding diagnosis, assessment, follow up and treatment of pediatric localized scleroderma cases, both of which suggest the Localized Scleroderma Cutaneous Assessment Tool as an important instrument to assess activity and damage. This review focuses on the systemic treatment of jLS. Systemic treatment includes synthetic and biologic disease-modifying antirheumatic drugs. Systemic therapy is indicated if the lesion crosses any joint, or leads to potential cosmetic disfiguration or orthopedic problems. The only controlled trial of systemic treatment has shown the efficacy of methotrexate, which is the first choice of treatment. It appears superior to phototherapy according to a recently published meta-analysis. In case of methotrexate intolerance, mycophenolate mofetil is an option. In case of methotrexate nonresponse, addition of mycophenolate mofetil, tocilizumab or abatacept seems to be effective. Future treatment options derived and extrapolated from adult trials regarding treatment of skin involvement of systemic scleroderma or fibrosis are promising, as the final pathway in the skin seems to be similar in both diseases.
