A systematic review of morphea treatments and therapeutic algorithm

Scleroderma-like Lesions in a Patient Undergoing Combined Pembrolizumab and Routine Chemotherapy: A Case Report and Literature Review

Triple-negative breast cancer (TNBC) represents a challenging malignancy with limited treatment options and a poor prognosis. Adjuvant therapies, including chemotherapy and immune checkpoint inhibitors (ICI), are commonly employed following breast conservation surgery. However, these treatments can lead to various adverse effects, including cutaneous complications and connective tissue disorders. Here, we present the case of a 54-year-old woman with TNBC who developed morphea, a form of localized scleroderma, following adjuvant chemotherapy and pembrolizumab administration. This case highlights the rarity of drug-induced morphea and emphasizes the importance of recognizing and managing such adverse events in breast cancer patients. We discuss the clinical characteristics, diagnostic challenges, and treatment considerations associated with drug-induced scleroderma-like lesions, as well as the potential mechanisms underlying their development. Furthermore, we review the literature on the incidence, clinical features, and outcomes of scleroderma-like lesions induced by chemotherapy and ICIs. This case underscores the need for increased awareness of immune-related adverse events in patients receiving immunotherapy, as well as the importance of individualized treatment approaches to optimize patient care and outcomes.

Clinical and ultrasonographic evaluation of efficacy and safety of intralesional injection of autologous platelet-rich plasma in morphea: A comparative case series

Objective

To evaluate the efficacy and safety of platelet-rich plasma to restore skin changes in morphea by ultrasound and Localized Scleroderma Cutaneous Assessment Tool.

Methods

Nine morphea patients (21 lesions) were diagnosed clinically and by histopathology. Intradermal platelet-rich plasma was injected into morphea lesion once weekly for 12 sessions. The disease severity and damage were evaluated at baseline, after the last session (3 months later), and at 6 months follow-up using the LoSCAT and a high-resolution ultrasound. The healthy corresponding side was considered as a control.

Results

The Localized Scleroderma Cutaneous Assessment Tool score showed a significant improvement starting from 13 ± 7.28 up to 7.33 ± 6.82 after the therapeutic endpoint, reaching to 6.44 ± 7.09 after 6 months of follow-up with p value = 0.008 and 0.014, respectively. There was a significant positive correlation between the duration of the lesion and the improvement assessed by the ultrasound, with p value = 0.01. Regarding adverse effects, all patients reported having pain during platelet-rich plasma injection; transient edema of the face was reported by four patients (45%), and only two patients showed transient erythema.

Conclusion

Autologous platelet-rich plasma is a safe technique with great aesthetic outcomes for filling up the contour defects and correcting both hyper and hypopigmentation, in addition to softening the indurated lesions.

Hyaluronic Acid Filler Injection for Localized Scleroderma - Case Report and Review of Literature on Filler Injections for Localized Scleroderma

Introduction

Localized scleroderma, also known as Morphea, is a chronic inflammatory condition of connective tissue, the etiology of which is unknown. There is skin thickening with increased quantities of collagen in the indurative lesion. Skin hyperemia is seen in the early inflammatory stage. This is followed by fibrosis, sclerosis, and atrophy with hypopigmentation or hyperpigmentation. Therapeutic options include corticosteroids, oral or subcutaneous methotrexate, calcipotriol, imiquimod, tacrolimus, mycophenolate mofetil, medium-dose UVA1 phototherapy, and CO₂ fractional laser treatment. There is disfigurement in approximately 50% of patients. Surgical excision, autologous bone grafting, and autologous fat grafting have been performed with varying degrees of success in linear morphea. Hyaluronic acid, Calcium hydroxylapatite, Poly L lactic acid, and permanent fillers such as Silicone have been used to correct deformities that occur as a result of morphea. The aim of this case report was to establish hyaluronic acid fillers as an efficacious modality of treating stable localized morphea with facial disfigurement.

Case Report

A 35-year-old lady with stable localized scleroderma had an atrophic scar on the right side of her face extending from the labio-mental crease to the midline of the chin. The contour of the chin was lost leading to facial disfigurement. The atrophic scar was treated with 2 fillers with the same cross-linking polymer but two different G primes with excellent cosmetic outcome. A brief review of literature involving fillers for localized scleroderma is also discussed.

Conclusion

Hyaluronic acid filler can be used safely in cases of stable localized scleroderma with facial atrophies. It is an effective, minimally invasive treatment with minimal downtime. It is extremely important to inject fillers only in stable cases of localized morphea. This modality of treatment should be considered for a larger trial in patients with similar disfigurements.

Assessing the compliance of systematic review articles published in leading dermatology journals with the PRISMA statement guidelines: A systematic review

Background

Reporting quality of systematic reviews and meta-analyses is of critical importance in dermatology because of their key role in informing health care decisions.

Objective

To assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement guidelines.

Methods

This review was carried out in accordance with PRISMA guidelines. Included studies were reviews published across 6 years in the top 4 highest-impact-factor dermatology journals of 2017. Records and full texts were screened independently. Data analysis was conducted with univariate multivariable linear regression. The primary outcome was to assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the PRISMA statement.

Results

A total of 166 studies were included and mean PRISMA compliance across all articles was 73%. Compliance significantly improved over time (β = .016; P = <.001). The worst reported checklist item was item 5 (reporting on protocol existence), with a compliance of 15% of articles.

Conclusion

PRISMA compliance within leading dermatology journals could be improved; however, it is steadily improving.

Laser Therapy for the Treatment of Morphea: A Systematic Review of Literature

Morphea, also known as localized scleroderma (LoS), comprises a set of autoimmune sclerotic skin diseases. It is characterized by inflammation and limited thickening and induration of the skin; however, in some cases, deeper tissues might also be involved. Although morphea is not considered a life-threatening disease, the apparent cosmetic disfigurement, functional or psychosocial impairment affects multiple fields of patients’ quality of life. Therapy for LoS is often unsatisfactory with numerous treatments that have only limited effectiveness or considerable side effects. Due to the advances in the application of lasers and their possible beneficial effects, the aim of this study is to review the reported usage of laser in morphea. We present a systematic review of available literature, performed with MEDLINE, Cinahl, Central, Scopus, Web of Science, and Google Scholar databases. We identified a total of twenty relevant studies (MEDLINE n = 10, Cinahl n = 1, Central n = 0, Scopus n = 2, Web of Science n = 5, Google Scholar n = 2) using laser therapy for LoS. Eight studies were focused on the use of PDL, six on fractional lasers (CO₂ and Er:YAG), four on excimer, and two on either alexandrite or Nd:YAG.

A Case of Recalcitrant Linear Morphea Responding to Subcutaneous Abatacept

INTRODUCTION

Linear morphea is an inflammatory condition that is often treated with systemic glucocorticoids and methotrexate, with mycophenolate mofetil being used as an alternative agent. However, there are few published reports on beneficial effect of abatacept for refractory disease. We present a case of a woman in her 30s who presented with linear morphea on her scalp, with a notable response following the addition of subcutaneous abatacept.

METHODS

Computational analysis was performed comparing the immune cell scores of skin biopsies from 5 morphea skin biopsies from 3 unique patients and 15 healthy control skin biopsies. P < 0.05 was considered statistically significant.

RESULTS

Immune cell scores demonstrated a statistically significant enrichment of activated CD4 memory T cells, M1 macrophages, monocytes, and memory B cells comparing skin biopsies of morphea vs healthy controls (p < 0.05 for all).

DISCUSSION

Abatacept may be considered for recalcitrant cases of morphea. Our computational analysis supports a well-designed study to assess abatacept as first line therapy.

Morphea: progress to date and the road ahead

Morphea is a rare autoimmune condition causing inflammation and sclerosis of the skin and underlying soft tissue. It is characterized by periods of activity (inflammation admixed with fibrosis), ultimately resulting in permanent damage (pigment change and tissue loss). Damage resulting from unchecked activity can lead to devastating, permanent cosmetic and functional sequelae including hair loss; cutaneous, soft tissue and bony atrophy; joint contractures; and growth restriction of the affected body site in children. This makes the early identification of activity and initiation of appropriate treatment crucial to limiting damage in morphea. To this end, recent investigative work has focused on validation of clinical, biomarker, imaging, and histologic outcomes aimed at accurately quantifying activity and damage. Despite promising results, further work is needed to better validate these measures before they can be used in the clinic and research settings. Although there has been recent approval of less toxic, targeted therapies for many inflammatory skin conditions, none have been systematically investigated in morphea. The mainstays of treatment for active morphea are corticosteroids and methotrexate. These are often limited by substantial toxicity. The paucity of new treatments for morphea is the result of a lack of studies examining its pathogenesis, with many reviews extrapolating from research in systemic sclerosis. Recent studies have demonstrated the role of dysregulated immune and fibrotic pathways in the pathogenesis of morphea, particularly interferon (IFN) gamma related pathways. Active morphea lesions have been found to display an inflammatory morphea signature with CXCR3 receptor ligands, as well as a distinct fibrotic signature reflecting fibroblast activation and collagen production. CXCL9 and 10 have been associated with increased measures of disease activity. While immune dysfunction is thought to play the primary role in morphea pathogenesis, there are other factors that may also contribute, including genetic predisposition, environmental factors, and vascular dysregulation. There remains an essential need for further research to elucidate the pathogenesis of morphea and the mode of action of dysregulated upstream and downstream immune and fibrotic pathways. These studies will allow for the discovery of novel biomarkers and targets for therapeutic development.

Plasticity of Treg and imbalance of Treg/Th17 cells in patients with systemic sclerosis modified by FK506

To determine the effects of Tacrolimus (FK506) on Treg cells and subpopulations in SSc patients and assess the ability of FK506 to modify the immune imbalance of Treg/Th17 cells. We analyzed PBMC from five SSc patients and six healthy control by flow cytometry after cultured with 0, 0.1, 1, or 10 ng/ml FK506 in vitro. The number of Treg cells decreased in SSc patients treated with FK506. The number of FrI cells were decreased in SSc following FK506 treatment. The drug did increase the frequency of FrII/Treg cells, but not FrII cells. However, FK506 significantly decreased FrIII in both SSc patients and controls. FK506 clearly decreased the numbers of Th17 cells and FoxP3⁺IL-17⁺ cells. The proliferation capacity of cells was also inhibited by FK506, which had a greater effect on FoxP3^- cells than FoxP3⁺ cells. FK506 did inhibit the proliferation of FrIII cells, but not FrI or FrII cells. Our study provides that FK506 reduced the number of FoxP3^low CD45RA^- T cells (FrIII) by inhibiting its proliferation. Therefore, FK506 modifies Treg cells and the immune imbalance between Tregs and Th17 cells in SSc patients.

Clinical Treatment Options in Scleroderma: Recommendations and Comprehensive Review

There are two major clinical subsets of scleroderma: (i) systemic sclerosis (SSc) is a complex systemic autoimmune disorder characterized by inflammation, vasculopathy, and excessive fibrosis of the skin and multiple internal organs and (ii) localized scleroderma (LoS), also known as morphea, is confined to the skin and/or subcutaneous tissues resulting in collagen deposition and subsequent fibrosis. SSc is rare but is associated with significant morbidity and mortality compared with other rheumatic diseases. Fatal outcomes in SSc often originate from organ complications of the disease, such as lung fibrosis, pulmonary artery hypertension (PAH), and scleroderma renal crisis (SRC). Current treatment modalities in SSc have focused on targeting vascular damage, fibrosis, and regulation of inflammation as well as autoimmune responses. Some drugs previously used in an attempt to suppress fibrosis, like D-penicillamine (D-Pen) or colchicine, have been disappointing in clinical practice despite anecdotal evidence of their advantages. Some canonical medications, including glucocorticoids, immunosuppressants, and vasodilators, have had some success in treating various manifestations in SSc patients. Increasing evidence suggests that some biologic agents targeting collagen, cytokines, and cell surface molecules might have promising therapeutic effects in SSc. In recent years, hematopoietic stem cell transplantation (HSCT), mostly autologous, has made great progress as a promising treatment option in severe and refractory SSc. Due to the complexity and heterogeneity of SSc, there are currently no optimal treatments for all aspects of the disease. As for LoS, local skin-targeted therapy is generally used, including topical application of glucocorticoids or other immunomodulatory ointments and ultraviolet (UV) irradiation. In addition, systemic immunosuppressants are also utilized in several forms of LoS. Here, we comprehensively discuss current treatment options for scleroderma, encompassing old, new, and future potential treatment options. In addition, we summarize data from new clinical trials that have the potential to modify the disease process and improve long-term outcomes in SSc.

Evaluation of the Effectiveness and Tolerability of Mycophenolate Mofetil and Mycophenolic Acid for the Treatment of Morphea

Importance

First-line systemic therapy for morphea includes methotrexate with or without systemic corticosteroids. When this regimen is ineffective, not tolerated, or contraindicated, a trial of mycophenolate mofetil (MMF) or mycophenolic acid (MPA)-referred to herein as mycophenolate-is recommended; however, evidence to support this recommendation remains weak.

Objective

To evaluate the effectiveness and tolerability of mycophenolate for the treatment of morphea.

Design, Setting, and Participants

A retrospective cohort study was conducted from January 1, 1999, to December 31, 2018, among 77 patients with morphea from 8 institutions who were treated with mycophenolate.

Main Outcomes and Measures

The primary outcome was morphea disease activity, severity, and response at 0, 3 to 6, and 9 to 12 months of mycophenolate treatment. A secondary outcome was whether mycophenolate was a well-tolerated treatment of morphea.

Results

There were 61 female patients (79%) and 16 male patients (21%) in the study, with a median age at disease onset of 36 years (interquartile range, 16-53 years) and median diagnostic delay of 8 months (interquartile range, 4-14 months). Generalized morphea (37 [48%]), pansclerotic morphea (12 [16%]), and linear morphea of the trunk and/or extremities (9 [12%]) were the most common subtypes of morphea identified. Forty-one patients (53%) had an associated functional impairment, and 49 patients (64%) had severe disease. Twelve patients received initial treatment with mycophenolate as monotherapy or combination therapy and 65 patients received mycophenolate after prior treatment was ineffective (50 of 65 [77%]) or poorly tolerated (21 of 65 [32%]). Treatments prior to mycophenolate included methotrexate (48 of 65 [74%]), systemic corticosteroids (42 of 65 [65%]), hydroxychloroquine (20 of 65 [31%]), and/or phototherapy (14 of 65 [22%]). After 3 to 6 months of mycophenolate treatment, 66 of 73 patients had stable (n = 22) or improved (n = 44) disease. After 9 to 12 months of treatment, 47 of 54 patients had stable (n = 14) or improved (n = 33) disease. Twenty-seven patients (35%) achieved disease remission at completion of the study. Treatments received in conjunction with mycophenolate were frequent. Mycophenolate was well tolerated. Gastrointestinal adverse effects were the most common (24 [31%]); cytopenia (3 [4%]) and infection (2 [3%]) occurred less frequently.

Conclusions and Relevance

This study suggests that mycophenolate is a well-tolerated and beneficial treatment of recalcitrant, severe morphea.

Targeted delivery in scleroderma fibrosis

Systemic sclerosis (SSc) is considered one of the most challenging and difficult to treat among rheumatic disorders, due to its severity, multiorgan manifestation and different outcomes. It manifests fibrosis in different organs, mostly in skin and lungs. The skin fibrosis expression is considered the first sign of the disease and usually it is followed by internal organ fibrosis. An aberrant immune system activation seems to relate to the expression of the disease, but even environmental influences and dysregulation of many molecules signalling pathways are involved in the development of the disease. Current therapies are limited and characterized by multiple side effects: systemic route is the elective administration route, which decreases patient adherence to the therapy, as they are often already bothered by pain and disfigurement. Treatments available are organ-based, originally indicated for other conditions and there is no therapy available to reduce the fibroblast population size within existing fibrotic lesions. Disease-modifying therapies or immunomodulatory agents that are highly effective in other rheumatic diseases have shown disappointing results in SSc. There are thus no standardized and effective treatments for this disease, and there are even unanswered questions related to the insurgence of the pathology and all the mechanisms involved. An ideal approach could be considered "targeted therapy" that will be an increasingly attainable objective insofar as our understanding of the disease improves. The advantages in identifying the molecule and the signalling pathways involved in the pathology have helped to find some novel compounds for the therapy of scleroderma fibrosis or following innovative uses for already-approved drugs, corroborated by many clinical studies.

Clinical characteristics and histopathologic changes of morphea: A single-center, retrospective study of 137 patients

BACKGROUND

The clinicopathologic correlations and prognostic risk factors for refractory disease in morphea (localized scleroderma) are poorly described.

OBJECTIVE

To investigate the association between clinical characteristics and histopathologic features of morphea and identify risk factors for refractory disease.

METHODS

We retrospectively reviewed the clinical and histopathologic features, treatment regimens, and clinical responses for 137 patients with biopsy-proven morphea from January 2008 to May 2019. Multivariate analysis was conducted to identify factors associated with poor treatment response.

RESULTS

We detected associations between the pattern and degree of sclerosis and the anatomic site of the lesion, as well as between severe inflammation and concomitant autoimmune disease. Additionally, both bottom-heavy sclerosis and increased inflammation were associated with functional limitations/clinical symptoms. Based on our multivariate analysis, we found that increased risk of poor treatment response was correlated with tissue eosinophils and basal pigmentation.

LIMITATIONS

This was a single-center retrospective study.

CONCLUSION

Skin biopsy samples could show specific features of morphea, including eosinophil infiltration and basal pigmentation, which may indicate the need for aggressive treatment and frequent monitoring.

Beneficial Effects of Near-Infrared Light Photobiomodulation in Linear Morphea: A Case Report

Background: Linear morphea is a variant of scleroderma limited to the skin and underlying tissues secondary to an autoimmune inflammation leading to excess collagen deposition and fibrosis. Apart from topical or oral medications, successful light-based treatments have been reported using phototherapy including Psoralen plus ultraviolet A, photodynamic therapy, carbon dioxide laser, pulsed dye laser, and visible/infrared light. Methods: We report a patient with biopsy-proven infraorbital linear morphea responding to 940 nm near-infrared light photobiomodulation treatments. Results: The patient had excellent cosmesis without textural changes or hypopigmentation despite her darker skin complexion (Fitzpatrick phototype III) after tri-weekly treatments for 8 months. Conclusions: Linear morphea, therefore, may be potentially amenable to home use light-based therapy by using nonthermal nonablative 940 nm photons. To our knowledge, this home-based treatment approach has not been previously reported.

Reproductive Tract Infection Among Women Suffering From Rheumatoid Arthritis in India: A Clinical-Based, Cross-Sectional Study

Background: Much research has been done on reproductive tract infections (RTIs), but no study exists about RTIs among rheumatoid arthritis women. Objectives: This study investigated the prevalence and risk factors of RTIs among reproductive-aged women with rheumatoid arthritis in Pune, India. Methods: This clinical-based, cross-sectional study enrolled a sample of 400 consenting Indian women aged 15 -49 years with a history of at least three months’ rheumatoid arthritis referring to a popular community center. Patients were interviewed comprehensively using previously validated relevant questionnaires. Women underwent gynecological examinations and vaginal smears (wet mount) by a microbiologist to diagnose candidiasis, bacterial vaginosis, and trichomoniasis. Syphilis serological testing was performed for the study population. Results: The prevalence obtained was 39.3%. Infection with bacterial vaginosis was 32.0%, Candidiasis 6.5%, and trichomoniasis 0.8%. Syphilis seroconversion was not observed. Adjusting for confounding factors in logistic regression showed that four factors remained significant, including age under 30 years [AOR: 2.4, 95% CI: 1.2 - 4.9], living in a crowded and small one-room house [AOR: 2.5, 95% CI: 1.2 - 5.1] , improper linen for menstruation bleeding [AOR: 1.9, 95% CI: 1.1 - 3.3], and oral disease-modifying anti-rheumatic drugs [AOR: 3.96, 95% CI: 1.9 - 7.9]. Conclusions: This study demonstrated a large burden of RTIs in women suffering from rheumatoid arthritis. Regular screening algorithms for RTIs are urgently required to prevent neglect and improve overall standard care in rheumatology practice. The presence of an oral disease-modifying anti-rheumatic drug as a risk factor shows that more investigation is necessary in this case.

Autologous fat grafting for the treatment of sclerotic lesions and scars

INTRODUCTION

Microfat grafting is a well-known technique that is underutilized in dermatology. Instead of removing sclerotic tissue, microfat grafting preserves the tissue and uses stem cells for remodeling its structure into normal tissue. We performed a retrospective study of patients treated with microfat grafting for sclerotic and atrophic skin lesions and scars.

PATIENTS AND METHODS

Seventy-two microfat grafts were performed using the Magalon technique under general anaesthesia for the treatment of sclerotic and atrophic skin lesions. We performed grafts for different indications, such as scars (n=55) and sclerotic and atrophic skin lesions (n=17: Parry-Romberg syndrome, morphea). The main outcome was assessed for satisfaction during follow-up. In addition, an independent committee judged the results based on photographs.

RESULTS

Satisfaction levels (e.g. results were judged to be "good") were almost 91% (n=50/55) for scars and 100% (n=17/17) for atrophic and sclerotic skin lesions. Satisfaction levels according to the independent committee were 94.1% for sclerotic and atrophic lesions and nearly 51% for scars.

CONCLUSION

Satisfaction was high after microfat grafting for atrophic and sclerotic skin lesions. Microfat grafting enabled restoration of the skin texture by exploiting stem cell properties. It is an efficient dermatological therapy for sclerotic and atrophic lesions, for which there are few alternative treatments.

Cosmetic treatment in patients with autoimmune connective tissue diseases: Best practices for patients with morphea/systemic sclerosis

Morphea and systemic sclerosis are inflammatory, sclerosing disorders. Morphea primarily affects the dermis and subcutaneous fat, while systemic sclerosis typically involves the skin and internal organs. Functional impairment and cosmetic disfigurement are common in both diseases. Treatment options to mitigate disease progression remain limited. Both functional impairment and cosmetic deficits negatively impact quality of life and psychological well-being in this patient population. While the number of cosmetic procedures performed in the United States continues to rise each year, limited data exist regarding best practices for correcting aesthetic deficits caused by autoimmune conditions. There is scarce information to guide safety decisions regarding laser parameters, soft tissue augmentation, treatment intervals, and the concurrent use of immune-modifying or immune-suppressing medications. Given the fears of disease reactivation and exacerbation from postprocedural inflammation along with limited data, it is difficult for clinicians to provide evidence-based cosmetic treatment with realistic expectations with regard to short- and long-term outcomes. In the first article in this continuing medical education series, we attempt to address this practice gap.

A retrospective study: Impact of consensus treatment plans on systemic therapy of pediatric morphea

BACKGROUND

Morphea is an inflammatory and fibrosing condition that affects the skin and subcutaneous structures. Morphea is managed by dermatologists, rheumatologists, or both. Prior studies have suggested there is significant variability in approach to treatment. In 2012, the Childhood Arthritis and Rheumatology Research Alliance (CARRA) published consensus treatment plans (CTPs) for pediatric morphea to develop more standardized treatment plans for patients requiring systemic therapy. We aimed to assess whether the publication of CTPs has impacted care of patients with morphea at our institution.

METHODS

Data were collected via a retrospective review of medical records of 61 pediatric patients diagnosed with morphea at Seattle Children's Hospital (SCH) from January 1, 2005, to December 12,2017.

RESULTS

Prior to the publication of CTPs, 2 out of 24 patients (8.3%) were treated with a regimen that matched a subsequent CTP. After publication of CTPs, 29 out of 37 patients (78.4%) were treated with a regimen that matched a CTP (P < 0.001). A subanalysis was performed to assess the number of patients who needed second- or third-line therapies. Of those who followed a CTP therapy plan (n = 26), 3 patients (11.5%) needed a second-line therapy compared with 11 patients (44%) in the no-CTP followed group (n = 25), (P = 0.012).

CONCLUSIONS

The publication of CTPs led to a significant change in treatment approach for patients with morphea requiring systemic therapy at SCH. Patients treated with one of the treatment plans recommended by the CTPs were less likely to need second-line systemic therapy.

Off-Label Use of Topical Calcineurin Inhibitors in Dermatologic Disorders

Off-label prescribing is a common practice in dermatology, particularly when uncommon dermatologic diseases have limited or no approved treatment options. Topical calcineurin inhibitors are approved for the treatment of eczema, and their anti-inflammatory, immunomodulatory, and steroid-sparing effects make them an attractive therapeutic option for a wide variety of other dermatologic diseases. This review summarizes and qualifies the available evidence supporting the clinical effectiveness of tacrolimus ointment and pimecrolimus cream in non-eczema indications. There is high-quality evidence supporting the effectiveness of topical calcineurin inhibitors in multiple dermatological disorders including vitiligo; psoriasis of the face, folds, and genitals; seborrheic dermatitis; chronic hand dermatitis; contact dermatitis; oral lichen planus; lichen sclerosus; morphea; and cutaneous lupus erythematosus. Lower-quality evidence suggests they may be considered as an option in many other cutaneous disorders.

Overview of Juvenile localized scleroderma and its management

BACKGROUND

Juvenile localized scleroderma (JLS) is a rare pediatric disease characterized by inflammation and skin thickening. JLS is associated with deep tissue and extracutaneous involvement that often results in functional impairment and growth disturbances. This article provides an overview of the disease with a focus on active features and treatment.

DATA SOURCES

We searched databases including PubMed, Elsevier and MedLine and Wanfang, reviewing publications from 2013 to 2019. Selected earlier publications were also reviewed.

RESULTS

Linear scleroderma is the most common JLS subtype. Several lines of evidence suggest that JLS is an autoimmune disease. Extracutaneous involvement is common and can present before the onset of skin disease. Multiple skin features are associated with disease activity, and activity can also manifest as arthritis, myositis, uveitis, seizures, and growth impairment. Systemic immunosuppressive treatment, commonly methotrexate with or without glucocorticoids, greatly improves outcome and is recommended for treating JLS patients with active disease and moderate or higher severity. Long term monitoring is needed because of the disease's chronicity and the high frequency of relapses off of treatment.

CONCLUSIONS

JLS is associated with a risk for disabling and disfiguring morbidity for the growing child. Identifying active disease is important for guiding treatment, but often difficult because of the paucity of markers and lack of a universal skin activity feature. More studies of JLS pathophysiology are needed to allow the identification of biomarkers and therapeutic targets. Comparative effectiveness treatment studies are also needed to work towards optimizing care and outcome.

Interventions for morphea

BACKGROUND

Morphea (morphoea) is an immune-mediated disease in which excess synthesis and deposition of collagen in the skin and underlying connective tissues results in hardened cutaneous areas. Morphea has different clinical features according to the subtype and stage of evolution of the disease. There is currently no consensus on optimal interventions for morphea.

OBJECTIVES

To assess the effects of treatments for people with any form of morphea.

SEARCH METHODS

We searched the following databases up to July 2018: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, and five trial registers. We checked the reference lists of included studies for further references to relevant randomised controlled trials.

SELECTION CRITERIA

Randomised controlled trials of topical, intralesional, or systemic treatments (isolated or combined) in anyone who has been clinically diagnosed by a medical practitioner with any form of morphea. Eligible controls were placebo, no intervention, any other treatment, or different doses or duration of a treatment.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. The primary outcomes were global improvement of disease activity or damage assessed by a medical practitioner or by participants, and adverse effects. Secondary outcomes were improvement of disease activity and improvement of disease damage. We used GRADE to assess the quality of the evidence for each outcome.

MAIN RESULTS

We included 14 trials, with a total of 429 randomised participants, aged between 3 and 76 years. There were juvenile and adult participants; over half were female, and the majority had circumscribed morphea, followed by linear scleroderma. The settings of the studies (where described) included a dermatologic centre, a national laboratory centre, paediatric rheumatology and dermatology centres, and a university hospital or medical centre.The studies evaluated heterogenous therapies for different types of morphea, covering a wide range of comparisons. We were unable to conduct any meta-analyses. Seven studies investigated topical medications, two evaluated intralesional medications, and five investigated systemic medications. The study duration ranged from seven weeks to 15 months from baseline.We present here results for our primary outcomes for our four key comparisons. All of these results are based on low-quality evidence.The included studies were at high risk of performance, detection, attrition, and reporting bias.Global improvement of disease activity or damage after treatment may be higher with oral methotrexate (15 mg/m², maximum 20 mg, once a week, for 12 months or until disease flare) plus oral prednisone (1 mg/kg a day, maximum of 50 mg, in a single morning dose, for three months, and one month with gradually decreased dose until discontinuation) than with placebo plus oral prednisone in children and adolescents with active morphea (linear scleroderma, generalised morphea or mixed morphea: linear and circumscribed) (risk ratio (RR) 2.31, 95% confidence interval (CI) 1.20 to 4.45; number needed to treat for an additional beneficial outcome (NNTB) 3; 1 randomised controlled trial (RCT); 70 participants, all juvenile). This outcome was measured 12 months from the start of treatment or until flare of the disease. Data were not available separately for each morphea type. There may be little or no difference in the number of participants experiencing at least one adverse event with oral methotrexate (26/46) or placebo (11/24) (RR 1.23, 95% CI 0.75 to 2.04; 1 RCT; 70 participants assessed during the 12-month follow-up). Adverse events related to methotrexate included alopecia, nausea, headache, fatigue and hepatotoxicity, whilst adverse events related to prednisone (given in both groups) included weight gain (more than 5% of body weight) and striae rubrae.One three-armed RCT compared the following treatments: medium-dose (50 J/cm²) UVA-1; low-dose (20 J/cm²) UVA-1; and narrowband UVB phototherapy. There may be little or no difference between treatments in global improvement of disease activity or damage, as assessed through the modified skin score (where high values represent a worse outcome): medium-dose UVA-1 phototherapy versus low-dose UVA-1 group: MD 1.60, 95% CI -1.70 to 4.90 (44 participants); narrowband UVB phototherapy versus medium-dose UVA-1 group: MD -1.70, 95% CI -5.27 to 1.87 (35 participants); and narrowband UVB versus low-dose UVA-1 group: MD -0.10, 95% CI -2.49 to 2.29 (45 participants). This RCT included children and adults with active morphea (circumscribed morphea, linear scleroderma (with trunk/limb variant and head variant), generalised morphea, or mixed morphea), who received phototherapy five times a week, for eight weeks. Outcomes were measured at eight weeks from the start of treatment.Safety data, measured throughout treatment, from the same RCT (62 participants) showed that treatment with UVA-1 phototherapy may cause mild tanning compared to narrowband UVB: narrowband UVB versus medium-dose UVA-1: RR 0.03, 95% CI 0.00 to 0.42; 35 participants; narrowband UVB versus low-dose UVA-1: RR 0.03, 95% CI 0.00 to 0.41; 45 participants. However, there may be no difference in the number of participants reporting mild tanning when comparing medium and low dose UVA-1 phototherapy (RR 1.00, 95% CI 0.91 to 1.10; 44 participants). Transient erythema was reported in three participants with narrowband UVB and no participants in the low- or medium-dose UVA-1 groups.

AUTHORS' CONCLUSIONS

Compared to placebo plus oral prednisone, oral methotrexate plus oral prednisone may improve disease activity or damage in juvenile active morphea (linear scleroderma, generalised morphea or mixed morphea: linear and circumscribed), but there may be a slightly increased chance of experiencing at least one adverse event.When medium-dose UVA-1 (50 J/cm²), low-dose UVA-1 (20 J/cm²), and narrowband UVB were compared against each other in treating children and adults with active morphea (circumscribed morphea, linear scleroderma, generalised morphea and mixed morphea), there may be little or no difference between these treatments on global improvement of disease activity or damage. UVA-1 phototherapy may cause more mild tanning than narrowband UVB, but there may be no difference between medium- and low-dose UVA-1 phototherapy. These results are based on low-quality evidence.Limitations of data and analyses include risk of bias and imprecision (small number of participants or events and wide confidence intervals). We encourage multicentre RCTs to increase sample size and evaluate, with validated tools, different treatment responses according to the subtypes of morphea and age groups.

Treatment of morphea with hydroxychloroquine: A retrospective review of 84 patients at Mayo Clinic, 1996-2013

BACKGROUND

Few studies support treating morphea (localized scleroderma) with hydroxychloroquine.

OBJECTIVE

To assess the efficacy of hydroxychloroquine treatment of morphea.

METHODS

We conducted a retrospective study of 84 patients who had morphea and were treated with hydroxychloroquine monotherapy for at least 6 months at our institution from 1996 through 2013. The median times to initial and maximal responses were assessed.

RESULTS

Of the 84 patients (median age at diagnosis, 29.5 years), 65 (77.4%) were female, 36 (42.9%) had a complete response to hydroxychloroquine, 32 (38.1%) had a partial response greater than 50%, 10 (11.9%) had a partial response less than or equal to 50%, and 6 (7.1%) had no response. The median time to initial response was 4 months, and the median time to maximal response was 12 months. Ten patients (11.9%) experienced adverse effects from hydroxychloroquine; the most common adverse effect was nausea (6 patients).

LIMITATIONS

Retrospective study.

CONCLUSIONS

Hydroxychloroquine is a valuable treatment for morphea because of its high response rate and low rate of adverse effects; however, prospective studies are needed to determine its true efficacy.

Development of minimum standards of care for juvenile localized scleroderma

Juvenile localized scleroderma (jLS), also known as morphea, is an orphan disease. Pediatric guidelines regarding diagnosis, assessment, and management are lacking.Our objective was to develop minimum standards of care for diagnosis, assessment, and management of jLS. A systematic review was undertaken to establish the pediatric evidence for assessment and monitoring of jLS. An expert panel, including members of the Pediatric Rheumatology European Society (PRES) Scleroderma Working Group, were invited to a consensus meeting where recommendations were developed based on evidence graded by the systematic review and, where evidence was lacking, consensus opinion. A nominal technique was used where 75% consensus was taken as agreement. Recommendations for diagnosis, assessment, and management were developed. Due to a lack of pediatric evidence, these were primarily consensus driven. Careful assessment for extra-cutaneous manifestations including synovitis, brain involvement, and uveitis were key features together with joint assessments between Dermatology and Rheumatology to improve and standardize care.

CONCLUSION

Management of jLS is varied. These recommendations should help provide standardization of assessment and care for those with this rare and potentially debilitating condition. What is Known: • Children with juvenile localized scleroderma (jLS) are managed by a number of specialties including pediatric rheumatologists and dermatologists, sometimes in shared clinics. Studies have shown that management varies considerably and that there are notable differences between specialties [1]. • There is very little published guidance on management of jLS. What is new: • These recommendations aim to standardize diagnosis, assessment, and management through review of pediatric evidence and consensus agreement. • Joint review of patients by both pediatric rheumatologists and dermatologists is recommended.

Diagnostic criteria, severity classification and guidelines of localized scleroderma

We established diagnostic criteria and severity classification of localized scleroderma because there is no established diagnostic criteria or widely accepted severity classification of the disease. Also, there has been no clinical guideline for localized scleroderma, so we established its clinical guideline ahead of all over the world. 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 localized scleroderma.

Juvenile Localized Scleroderma with Hyaline Deposits in the Renal Arteriole

We report a 10-year-old boy with localized scleroderma of the linear and plaque type, who showed proteinuria and hematuria. In this patient, skin, articular, and renal manifestations appeared successively and then began to resolve in the same order. A renal biopsy specimen demonstrated mild mesangial cell proliferation, exudate of immunoglobulin in the glomerular capillary, and large electron-dense deposits in the afferent arteriole. We consider that there were some transient factors that had caused the skin and articular manifestations, which also induced renal vascular inflammatory responses.

Generalized morphea/eosinophilic fasciitis overlap after epoxy exposure

Generalized morphea is associated with epoxy resin vapors and is characterized by the development of lesions shortly after exposure. Morphea presenting along with eosinophilic fasciitis (EF), or morphea/EF overlap, is rare and an indicator of poor prognosis and resistance to treatment. Here we present a case of generalized morphea/EF overlap linked to epoxy exposure. Our patient received multiple therapies-ultraviolet A1 phototherapy, prednisone, methotrexate, azathioprine, mycophenolate mofetil, cyclophosphamide, cyclosporine, and rituximab-none of which led to a significant response. The refractory nature of this disease warrants vigilance in its association with epoxy exposure.

Methotrexate: an effective monotherapy for refractory generalized morphea

Introduction

Morphea is an inflammatory skin disorder characterized by excessive collagen deposition. Although treatment algorithms for morphea subtypes have been suggested, no consistent recommendations are available. This study attempts to evaluate the clinical efficacy of methotrexate (MTX) as monotherapy in refractory generalized morphea.

Methods

It is a retrospective study, including 20 patients who had already been treated with various topical and systemic therapies with minimal clinical improvement. Patients received orally MTX at a of dosage 15 mg once weekly. Duration of the use, dosage of MTX, and adverse events were recorded. Clinical assessment of skin lesions was performed and documented.

Results

The mean disease duration was 27 months before the initiation of MTX treatment. After 12 months of therapy, very good response was achieved in 6 patients (30%), good response in 10 patients (50%), and fair response in 2 patients (10%), while 2 patients (10%) had failed treatment. Patients were followed up for a mean time interval of 21 months. No serious adverse event was recorded.

Conclusion

MTX has been already proved to be an effective and well-tolerated treatment in pediatric patients with morphea. The majority of the group of adult patients showed very good and good improvement when treated with MTX. Although this is an uncontrolled study, MTX monotherapy was considered a safe and effective treatment for the management of this specific clinical subset of morphea in adults.

Practice and Educational Gaps in Lupus, Dermatomyositis, and Morphea

Patients with skin-predominant lupus erythematosus, dermatomyositis, and morphea should be evaluated, treated, and followed by dermatologists who can take primary responsibility for their care. Many academic centers have specialized centers with dermatologists who care for these patients. Patients with skin-predominant lupus erythematosus should be followed regularly with laboratory tests to detect significant systemic disease. Antibody tests can help determine the risks for individual patients. Patients with morphea rarely progress to systemic disease, but therapies can be helpful in treating and preventing progression of disease.

Retinoic acid for treatment of systemic sclerosis and morphea: A literature review

Systemic sclerosis and morphea are connective tissue diseases characterized by tightening, thickening, and hardening of the skin, leading to significant morbidity. Unfortunately, current treatment options have limited efficacy for many patients. Cutaneous manifestations of these diseases arise from excess collagen deposition and fibrosis in the skin, through pathogenic mechanisms which have yet to be extensively detailed at the causal immune and cellular levels. Research elucidating the mechanism of action of retinoic acid on collagen production in the skin and case series highlighting the success of retinoic acid on the skin manifestations of systemic sclerosis and on morphea demonstrate its promise as a treatment. Herein they will briefly review the treatment options for both systemic sclerosis and morphea, and will discuss the potential of retinoic acid as a therapy and the supporting evidence from the literature, highlighting the previously published basic science and clinical studies investigating the role of retinoic acid in the treatment of sclerotic skin diseases.

Fractional carbon dioxide laser versus low-dose UVA-1 phototherapy for treatment of localized scleroderma: a clinical and immunohistochemical randomized controlled study

Morphea is a rare fibrosing skin disorder that occurs as a result of abnormal homogenized collagen synthesis. Fractional ablative laser resurfacing has been used effectively in scar treatment via abnormal collagen degradation and induction of healthy collagen synthesis. Therefore, fractional ablative laser can provide an effective modality in treatment of morphea. The study aimed at evaluating the efficacy of fractional carbon dioxide laser as a new modality for the treatment of localized scleroderma and to compare its results with the well-established method of UVA-1 phototherapy. Seventeen patients with plaque and linear morphea were included in this parallel intra-individual comparative randomized controlled clinical trial. Each with two comparable morphea lesions that were randomly assigned to either 30 sessions of low-dose (30 J/cm²) UVA-1 phototherapy (340-400 nm) or 3 sessions of fractional CO₂ laser (10,600 nm-power 25 W). The response to therapy was then evaluated clinically and histopathologically via validated scoring systems. Immunohistochemical analysis of TGF-ß1 and MMP1 was done. Patient satisfaction was also assessed. Wilcoxon signed rank test for paired (matched) samples and Spearman rank correlation equation were used as indicated. Comparing the two groups, there was an obvious improvement with fractional CO₂ laser that was superior to that of low-dose UVA-1 phototherapy. Statistically, there was a significant difference in the clinical scores (p = 0.001), collagen homogenization scores (p = 0.012), and patient satisfaction scores (p = 0.001). In conclusion, fractional carbon dioxide laser is a promising treatment modality for cases of localized morphea, with proved efficacy of this treatment on clinical and histopathological levels.

Autoimmune collagen vascular diseases: Kids are not just little people

Morphea, dermatomyositis (DM), and discoid lupus erythematosus (DLE) are autoimmune collagen vascular diseases that can present at any age. In all three of these diseases, the tenants of diagnosis and treatment are largely the same in both children and adults, with a few notable differences. Children with morphea are more likely to present with the linear subtype and have a higher incidence of extracutaneous manifestations. Children often need early aggressive systemic treatment to try to prevent long-term sequelae of morphea. In DM, adult disease has a clear association with malignancy that is not seen in children. Adults have a higher rate of pulmonary involvement and increased mortality, whereas calcinosis is more common in juvenile DM. DLE in adults is generally considered to have a low rate of progression from discoid lesions alone to systemic lupus erythematosus (SLE). DLE is less common in children, but several studies have suggested a higher rate of progression from DLE to SLE in children compared with adults.

Current and future direction in the management of scleroderma

Scleroderma is a heterogeneous disease with a complex etiology. As more information is gained about the underlying mechanisms and the improved classifications of scleroderma subtypes, treatments can be better personalized. Improving scleroderma patients' early diagnosis before end organ manifestations occur should improve clinical trial design and outcomes. Two recently FDA-approved antifibrotics for idiopathic pulmonary fibrosis may be effective treatments in patients with pulmonary fibrosis secondary to scleroderma after further investigation. The potential impact of Nanobiotechnology in improving the efficacy and safety of existing antifibrotics and immunomodulators might present an exciting new approach in the management of scleroderma.

Keloidal Scleroderma: Case Report and Review

Objective. We report a rare case of keloidal scleroderma and provide an analysis of similar cases. Results. A 41 year-old woman presented with dark brown, indurated, exophytic nodules over the chest along with smaller hyperpigmented plaques scattered over the abdomen, with concomitant sclerodactyly. The clinical, laboratory, and pathological findings were consistent with a diagnosis of keloidal scleroderma. The patient was treated with methotrexate, resulting in reduced firmness of her plaques and no new lesions. A literature review of previously reported cases was performed using keywords including keloidal morphea, keloidal scleroderma, nodular morphea, and nodular scleroderma. In our review, the majority of patients were African American and female. 91% of cases had nodular lesions with distribution on the trunk. The majority of patients exhibited sclerodactyly and pulmonary involvement was reported in 28%1. The majority of patients were ANA positive (63%) and only 10% demonstrated anti-SCL-70 positivity. Conclusion. Keloidal scleroderma is a rare presentation, which can often be clinically confused with keloid and scar formation. Due to this being a rare variant, our knowledge of treatment options and efficacy is limited. Methotrexate could be considered as an initial treatment option for patients with progressive keloidal scleroderma.

Systemic sclerosis and localized scleroderma--current concepts and novel targets for therapy

Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Skin and organ fibrosis are key manifestations of SSc, for which no generally accepted therapy is available. Thus, there is a high unmet need for novel anti-fibrotic therapeutic strategies in SSc. At the same time, important progress has been made in the identification and characterization of potential molecular targets in fibrotic diseases over the recent years. In this review, we have selected four targeted therapies, which are tested in clinical trials in SSc, for in depths discussion of their preclinical characterization. Soluble guanylate cyclase (sGC) stimulators such as riociguat might target both vascular remodeling and tissue fibrosis. Blockade of interleukin-6 might be particularly promising for early inflammatory stages of SSc. Inhibition of serotonin receptor 2b signaling links platelet activation to tissue fibrosis. Targeting simultaneously multiple key molecules with the multityrosine kinase-inhibitor nintedanib might be a promising approach in complex fibrotic diseases such as SSc, in which many partially independent pathways are activated. Herein, we also give a state of the art overview of the current classification, clinical presentation, diagnostic approach, and treatment options of localized scleroderma. Finally, we discuss whether the novel targeted therapies currently tested in SSc could be used for localized scleroderma.

Corticosteroids in Myositis and Scleroderma

Idiopathic inflammatory myopathies (IIMs) involve inflammation of the muscles and are classified by the patterns of presentation and immunohistopathologic features on skin and muscle biopsy into 4 categories: dermatomyositis, polymyositis, inclusion body myositis, and immune-mediated necrotizing myopathy. Systemic corticosteroid (CS) treatment is the standard of care for IIM with muscle and organ involvement. The extracutaneous features of systemic sclerosis are frequently treated with CS; however, high doses have been associated with scleroderma renal crisis in high-risk patients. Although CS can be effective first-line agents, their significant side effect profile encourages concomitant treatment with other immunosuppressive medications to enable timely tapering.

Localized scleroderma: clinical spectrum and therapeutic update

Scleroderma is a rare connective tissue disease that is manifested by cutaneous sclerosis and variable systemic involvement. Two categories of scleroderma are known: systemic sclerosis, characterized by cutaneous sclerosis and visceral involvement, and localized scleroderma or morphea which classically presents benign and self-limited evolution and is confined to the skin and/or underlying tissues. Localized scleroderma is a rare disease of unknown etiology. Recent studies show that the localized form may affect internal organs and have variable morbidity. Treatment should be started very early, before complications occur due to the high morbidity of localized scleroderma. In this review, we report the most important aspects and particularities in the treatment of patients diagnosed with localized scleroderma.
