Topical calcipotriene for morphea/linear scleroderma

Consensus statement on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: Localized scleroderma, systemic sclerosis and overlap syndromes

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes.

S2k guideline: Diagnosis and therapy of localized scleroderma

The updated S2k guideline deals with the diagnosis and therapy of localized scleroderma (LoS). LoS represents a spectrum of sclerotic skin diseases in which, depending on the subtype and localisation, structures such as adipose tissue, muscles, joints, and bones may also be affected. Involvement of internal organs or progression to systemic sclerosis does not occur. LoS can be classified into four main forms: limited, generalized, linear, and mixed forms, with some additional subtypes. For cases of limited skin involvement, the guideline primarily recommends therapy with topical corticosteroids. UV therapy can also be recommended. In subtypes with severe skin or musculoskeletal involvement, systemic therapy with methotrexate is recommended. During the active phase of the disease, systemic glucocorticosteroids can be used additionally. In cases of methotrexate and steroid refractory courses, contraindications, or intolerance, mycophenolate mofetil, mycophenolic acid, or abatacept can be considered as second-line systemic therapies. In the case of linear LoS, autologous adipose-derived stem cell transplantation can also be performed for correcting soft tissue defects.

Best clinical practice in the treatment of juvenile systemic sclerosis: expert panel guidance - the result of the International Hamburg Consensus Meeting December 2022

INTRODUCTION

Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence of 3 in 1,000,000 children. Currently there is only one consensus treatment guideline concerning skin, pulmonary and vascular involvement for jSSc, the jSSc SHARE (Single Hub and Access point for pediatric Rheumatology in Europe) initiative, which was based on data procured up to 2014. Therefore, an update of these guidelines, with a more recent literature and expert experience, and extension of the guidance to more aspects of the disease is needed.

AREAS COVERED

Treatment options were reviewed, and opinions were provided for most facets of jSSc including general management, some of which differs from adult systemic sclerosis, such as the use of corticosteroids, and specific organ involvement, such as skin, musculoskeletal, pulmonary, and gastroenterology.

EXPERT OPINION

We are suggesting the treat to target strategy to treat early to prevent cumulative disease damage in jSSc. Conclusions are derived from both expert opinion and available literature, which is mostly based on adult systemic sclerosis (aSSc), given shared pathophysiology, extrapolation of results from aSSc studies was judged reasonable.

S2k‐Leitlinie: Diagnostik und Therapie der zirkumskripten Sklerodermie

Die vorliegende aktualisierte S2k‐Leitlinie befasst sich mit der Diagnostik und der Therapie der zirkumskripten Sklerodermie (ZS). Diese umfasst ein Spektrum sklerotischer Erkrankungen der Haut mit, je nach Subtyp und Lokalisation, möglicher Beteiligung von hautnahen Strukturen wie Fettgewebe, Muskulatur, Gelenke und Knochen. Ein Befall innerer Organe oder ein Übergang in eine systemische Sklerodermie treten nicht auf. Eingeteilt werden kann die ZS in die vier Hauptformen der limitierten, generalisierten, linearen und gemischten Form. Teilweise existieren weitere Unterformen. Bei limitiertem Hautbefall empfiehlt die Leitlinie primär eine Therapie mit topischen Kortikosteroiden. Eine UV‐Therapie kann ebenfalls sinnvoll sein. Bei Subtypen mit schwerem Hautbefall oder muskuloskelettalem Befall wird eine systemische Therapie mit Methotrexat empfohlen. In der aktiven Phase der Erkrankung können ergänzend systemische Glukokortikosteroide eingesetzt werden. Bei MTX‐ und Steroid‐refraktären Verläufen, Kontraindikation oder Unverträglichkeit sollten Mycophenolat‐Mofetil, Mycophenolsäure oder Abatacept als Systemtherapie der zweiten Wahl eingesetzt werden. Bei einer linearen ZS kann zudem eine autologe Fettstammzelltransplantation zur Korrektur von Weichteildefekten erfolgen.

Recent Advances in Treatment of Systemic Sclerosis and Morphea

Systemic sclerosis (SSc) and morphea are autoimmune sclerosing diseases that cause significant morbidity, and in the case of SSc, mortality. The pathogenesis of both SSc and morphea share vascular dysfunction, auto-reactive T cells and Th2-associated cytokines, such as interleukin 4, and overproduction of transforming growth factor beta (TGFβ). TGFβ stimulates fibroblast collagen and extra-cellular matrix production. Although morphea and SSc have similar pathogenic pathways and histological findings, they are distinct diseases. Recent advances in treatment of morphea, skin sclerosis in SSc, and interstitial lung disease in SSc are focused on targeting known pathogenic pathways.

[Juvenile localized scleroderma]

Juvenile scleroderma, often referred to as juvenile localized scleroderma or "morphea", is a rare inflammatory disease of the skin and skin-related structures, accompanied by local sclerosis and tissue fibrosis. Depending on the clinical manifestation, four different subtypes can be defined: limited, generalized, linear, and mixed. To prevent possible sequelae of the disease, the diagnosis should be made as early as possible and therapy should be initiated at specialized centers in multiprofessional pediatric and dermatologic collaboration. In this review, we present the main clinical, laboratory, and therapeutic characteristics of juvenile localized scleroderma and summarize recommendations.

En Coup de Sabre in a Pediatric Patient Treated With Calcipotriene

En coup de sabre (ECDS) is a form of linear scleroderma or morphea that distinctly appears on the forehead and/or frontoparietal scalp. We report a case of a 6-year-old female that presented with a linear, hyperpigmented scar on her left forehead extending to her scalp with resultant alopecia and discoloration in the affected area. The patient was subsequently treated with topical calcipotriene ointment and had an excellent response with normalization of the sclerotic skin, hair regrowth, and improved hyperpigmentation. This report demonstrates that a conservative approach to treating pediatric patients with ECDS via calcipotriene ointment can be safe and effective.

Development and Validation of the Morphea Activity Measure in Patients With Pediatric Morphea

Importance

Morphea is an insidious inflammatory disorder of the skin and deeper tissues. Determining disease activity is challenging yet important to medical decision-making and patient outcomes.

Objective

To develop and validate a scoring tool, the Morphea Activity Measure (MAM), to evaluate morphea disease activity of any type or severity that is easy to use in clinical and research settings.

Design, Setting, and Participants

This pilot diagnostic study was conducted from September 9, 2019, to March 6, 2020, in 2 phases: development and validation. During the development phase, 14 morphea experts (dermatologists and pediatric dermatologists) used a Delphi consensus method to determine items that would be included in the MAM. The validation phase included 8 investigators who evaluated the tool in collaboration with 14 patients with pediatric morphea (recruited from a referral center [Medical College of Wisconsin]) during a 1-day in-person meeting on March 6, 2020.

Main Outcomes and Measures

During the development phase, online survey items were evaluated by experts in morphea using a Likert scale (score range, 0-10, with 0 indicating not important and 10 indicating very important); agreement was defined as a median score of 7.0 or higher, disagreement as a median score of 3.9 or lower, and no consensus as a median score of 4.0 to 6.9. During the validation phase, reliability (interrater and intrarater agreement using intraclass correlation coefficients), validity (using the content validity index and κ statistics as well as correlations with the modified Localized Scleroderma Severity Index and the Physician Global Assessment of Activity using Spearman ρ coefficients), and viability (using qualitative interviews of investigators who used the MAM tool) were evaluated. Descriptive statistics were used for quantitative variables. Data on race and ethnicity categories were collected but not analyzed because skin color was more relevant for the purposes of this study.

Results

Among 14 survey respondents during the development phase, 9 (64.3%) were pediatric dermatologists and 5 (35.7%) were dermatologists. After 2 rounds, a final tool was developed comprising 10 items that experts agreed were indicative of morphea activity (new lesion in the past 3 months, enlarging lesion in the past 3 months, linear lesion developing progressive atrophy in the past 3 months, erythema, violaceous rim or color, warmth to the touch, induration, white-yellow or waxy appearance, shiny white wrinkling, and body surface area). The validation phase was conducted with 14 patients (median age, 14.5 years [range, 8.0-18.0 years]; 8 [57.1%] female), 2 dermatologists, and 6 pediatric dermatologists. Interrater and intrarater agreement for MAM total scores was good, with intraclass correlation coefficients of 0.844 (95% CI, 0.681-0.942) for interrater agreement and 0.856 (95% CI, 0.791-0.901) for intrarater agreement. Correlations between the MAM and the modified Localized Scleroderma Severity Index (Spearman ρ = 0.747; P < .001) and the MAM and the Physician Global Assessment of Activity (Spearman ρ = 0.729; P < .001) were moderately strong. In qualitative interviews, evaluators agreed that the tool was easy to use, measured morphea disease activity at a single time point, and should be responsive to changes in morphea disease activity over multiple time points.

Conclusions and Relevance

In this study, the MAM was found to be a reliable, valid, and viable tool to measure pediatric morphea activity. Further testing to assess validity in adults and responsiveness to change is needed.

Morphea: The 2023 update

Morphea, also known as localized scleroderma, is a chronic inflammatory connective tissue disorder with variable clinical presentations, that affects both adults and children. It is characterized by inflammation and fibrosis of the skin and underlying soft tissue, in certain cases even of the surrounding structures such as fascia, muscle, bone and central nervous system. While the etiology is still unknown, many factors may contribute to disease development, including genetic predisposition, vascular dysregulation, T_H1/T_H2 imbalance with chemokines and cytokines associated with interferon-γ and profibrotic pathways as well as certain environmental factors. Since the disease may progress to permanent cosmetic and functional sequelae, it is crucial to properly assess the disease activity and to initiate promptly the adequate treatment, thus preventing subsequent damage. The mainstay of treatment is based on corticosteroids and methotrexate. These, however, are limited by their toxicity, especially if applied long-term. Furthermore, corticosteroids and methotrexate often do not sufficiently control the disease and/or the frequent relapses of morphea. This review presents the current understanding of morphea by discussing its epidemiology, diagnosis, management and prognosis. In addition, it will describe recent pathogenetic findings, thus proposing potential novel targets for therapeutic development in morphea.

Vitamin D: Skin, sunshine, and beyond

Vitamin D is a steroid hormone of importance to the field of dermatology. Skin is unique in that it is the site of vitamin D synthesis upon sun exposure and a target organ for its activity. We explore the physiology and metabolic mechanism of action of vitamin D, as well as its effects on the skin. We also discuss the current evidence of the efficacy and safety of oral and topical vitamin D analogues on skin conditions such as psoriasis, atopic dermatitis, vitiligo, sunburn, actinic keratosis, and fibrosing skin disorders. Based on currently available scientific evidence, the National Academy of Medicine's recommended dietary allowance for vitamin D ranges from 400 IU to 800 IU daily based on age categories.

Pediatric morphea state-of-the-art literature review: Reframing morphea as a systemic disease

Pediatric morphea is an inflammatory, fibrosing dermatologic disorder. Although morphea may be localized to the skin and subcutaneous tissues, differentiating it from systemic sclerosis, there is increasing evidence that morphea is a manifestation of a systemic inflammatory process, with the potential to involve many organ systems. Given the potential risk for irreversible sequelae, pediatric morphea should be treated early and aggressively. Long-term disease monitoring is essential.

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.

Etiologic role of Borrelia burgdorferi in morphea: A case report

Morphea is an inflammatory skin disease with self-limited evolution, presenting as localized sclerosis of the skin and/or underlying tissues. The incidence is not exactly known; the disease occurs more frequently in women, and there is no sex prevalence. Pathogenesis of morphea remains still controversial. Several theories exist and the Borrelia burgdorferi infection is not yet elucidated. The aim of this report is to present the main mechanisms involved in the etiophatogenesis of morphea and also the thepapeutic options. A case of a 60-year-old woman is presented, who was referred to the clinic for an erythematous-violaceus, asymptomatic eruption, located on the trunk and legs, for appoximately 2 months. The patient's medical history revealed an infection with Borrelia 1 year previously. After diagnosis of morphea was established, and with systemic therapy (corticosteroids and methotrexate), the evolution was favorable.

Paediatric morphoea: a holistic review. Part 2: diagnosis, measures of disease activity, management and natural history

Paediatric morphoea is a debilitating fibrosing disorder of uncertain aetiology, affecting the skin and subcutaneous tissues. Defining optimum management strategies in paediatric morphoea remains an ongoing challenge, owing to the varied presentations and a relative paucity of paediatric-specific studies. We performed a literature search on PubMed, MEDLINE and Google Scholar, using keywords such as 'pediatric morphea', 'juvenile localised scleroderma' and 'juvenile systemic sclerosis'. Relevant studies, including randomized trials, reviews of standard current guidelines and original research articles, were selected and results analysed before summarizing them. In Part 1 of this review, we described the epidemiology, aetiopathogenesis and clinical classification; in this part, we discuss the diagnosis, markers of disease activity, management and natural history in paediatric morphoea.

The efficacy and safety of topical rapamycin-calcitriol for facial angiofibromas in patients with tuberous sclerosis complex: a prospective, double-blind, randomized clinical trial

BACKGROUND

The efficacy of topical rapamycin is well documented for tuberous sclerosis complex (TSC)-related facial angiofibromas (FAs). Calcitriol has been shown to lessen skin fibrosis and may be therapeutically beneficial to FAs.

OBJECTIVES

To evaluate whether topical rapamycin-calcitriol combination is an effective and safe treatment for TSC-related FAs.

METHODS

Fifty-two patients with TSC with FAs were enrolled in this prospective study including three 12-week periods. In period 1, either topical rapamycin 0·1% or calcitriol 0·0003% single-agent therapy vs. their combination was applied in a double-blind, left-right-randomized, split-face comparison. The primary outcome was the reduction of modified Facial Angiofibroma Severity Index (mFASI) at week 12. In period 2, the patients were reassigned to use on both cheeks the ointment that resulted in the better primary outcome in period 1. The treatment was discontinued in period 3 (week 25-36) and a follow-up mFASI was scored to evaluate the degree of recurrence.

RESULTS

The mean changes in mFASI at week 12 compared with baseline were -0·92, -0·44 and -1·09 for rapamycin (P ≤ 0·001), calcitriol (P = 0·039) and rapamycin-calcitriol combination (P ≤ 0·001), respectively. Although rapamycin-calcitriol combination and rapamycin had similar statistically significant decreases of mFASI at week 12, rapamycin-calcitriol combination resulted in faster improvement in erythema, greater reduction of papule elevation and longer durability after discontinuing treatment than rapamycin alone. The treatments were well tolerated.

CONCLUSIONS

This randomized clinical trial demonstrates that topical rapamycin-calcitriol combination therapy is an effective and safe regimen for TSC-related FAs. What is already known about this topic? Facial angiofibromas (FAs) cause substantial psychological distress in individuals with tuberous sclerosis complex (TSC), but invasive procedural treatments are not applicable to all patients. Topical rapamycin has been demonstrated as an effective and safe treatment regimen for TSC-related FAs. What does this study add? Compared with baseline (day 0), both topical rapamycin 0·1% and rapamycin 0·1%-calcitriol 0·0003% combination ointment achieved statistically significant reductions in modified Facial Angiofibroma Severity Index at week 12. Compared with rapamycin alone, extended use of the rapamycin-calcitriol combination regimen until week 24 showed more effectiveness in decreasing papule elevation and could maintain a longer therapeutic effect after treatment discontinuation.

Update on Management of Morphea (Localized Scleroderma) in Children

Juvenile localized scleroderma (morphea) is the predominant scleroderma in childhood which affects the skin and may extend to the underlying fascia, muscle, joints and bone. The assessment of activity and damage can be done with a validated instrument like LoSCAT. Disease classified as “low severity” which includes superficial plaque morphea can be treated with topical mid potent- potent steroids, tacrolimus, calcipotriol or imiquimod in combination with phototherapy. Methotrexate is recommended for linear, deep and generalized morphea. Steroids are effective in the early inflammatory stage and used in combination with methotrexate. Methotrexate is continued for at least 12 months after adequate response is achieved. Mycophenolate mofetil is given in cases where methotrexate is contraindicated or for those who do not respond to methotrexate. There are also reports of improvement of disease with ciclosporine and hydroxychloroquine. In severe cases, recalcitrant to standard therapy there may be a role for biologics, JAK inhibitors, and IVIG. Supportive measures like physiotherapy and psychiatric counseling are also important in the management of morphea. Orthopedic surgery and other measures like autologous fat transfer may be advocated once the disease is inactive.

New Features for Measuring Disease Activity in Pediatric Localized Scleroderma

Objective.

To identify clinical features that define disease activity in pediatric localized scleroderma (LS), and determine their specificity and importance.

Methods.

We conducted a multicenter prospective study of patients with active and inactive LS skin lesions. A standardized evaluation of a single designated study lesion per subject was performed at 3 visits. We evaluated the pattern and correlation between assessed features and physician’s global assessments of activity (PGA-A).

Results.

Ninety of 103 subjects had evaluable data; 66 had active and 24 inactive disease. Subjects had similar age of onset, sex, and disease patterns. Linear scleroderma was the most common subtype. Features specific for active disease included erythema, violaceous color, tactile warmth, abnormal skin texture, and disease extension. Scores for these variables changed over time and correlated with PGA-A of the lesion. Active and inactive lesions could not be distinguished by the presence or level of skin thickening, either of lesion edge or center. However, in active lesions, skin thickening scores did correlate with PGA–A scores. Regression analysis identified the combination of erythema, disease extension, violaceous color, skin thickening, and abnormal texture as predictive of PGA-A at study entry. Damage features were common irrespective of activity status.

Conclusion.

We identified variables strongly associated with disease activity, expanding upon those used in current measures, and determined their relative importance in physician activity scoring. Skin thickening was found to lack specificity for disease activity. These results will help guide development of a sensitive, responsive activity tool to improve care of patients with LS.

Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) adapted for use in adult patients: report from an initial validation study

BACKGROUND

Localized scleroderma (LoS) affects both children and adults and is associated with permanent functional and cosmetic impairment, and reduced quality of life predominating in adults. The Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) is a clinical instrument designed to measure an activity and damage of LoS. It has been validated for use with pediatric LoS patients. This study assessed the validity and reliability of the LoSCAT adapted for use in adults.

METHODS

Before the initiation of the study two examiners participated in an intensive training course carried out by an expert in LoS. Appendices describing each LoSCAT domain were prepared. Features determining disease activity and damage in adult LoS patients were identified to properly evaluate the physician (Phys) and patient (Pt) global assessment (GA) of disease activity (A)/severity (S) and damage (D), which were used to assess convergent validity of the LoSCAT. Correlations of physician- and patient-derivied measures with Skindex-29 were also analysed.

RESULTS

The study included 40 adult LoS patients (33 females and 7 males) with different subtypes of LoS. Intra and inter-rater reliability of the LoSCAT was found to be excellent. Positive correlations were observed between the PhysGA-A, PhysGA-D, PtGA-A and the LoSCAT's domains, while no correlations between them and the PtGA-D were found. There were no relationships between LoSCAT's components and Skindex-29.

CONCLUSIONS

Despite the LoSCAT is a reliable tool for an assessment of cutaneous lesions, additional health status instruments are necessary to a holistic approach to LoS in adults.

Cutaneous Manifestations of Scleroderma and Scleroderma-Like Disorders: a Comprehensive Review

Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct diagnosis and appropriate management.

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.

Discordance of pediatric morphea treatment by pediatric dermatologists

BACKGROUND/OBJECTIVES

Studies describing treatment efficacy in pediatric morphea are lacking. Subspecialists have reached no consensus on how to optimally treat pediatric morphea. The objective of the current study was to describe the most common treatment practices of pediatric dermatologists worldwide who care for children with morphea.

METHODS

A survey regarding topical treatment practices of pediatric morphea, with representative case-based scenarios, was distributed to pediatric dermatologists and results were tallied.

RESULTS

The survey response rate was 13.4%, with 110 respondents in the final analysis. The majority of respondents agreed on red violaceous rim (99%), increased local warmth (75%), raised borders (69%), and dermal thickening (64%) as signs of disease activity. Respondents had less agreement on sclerotic lesions (41%), scaling (43%), dyspigmentation (19%), and atrophy (13%) as signs of disease activity. Ninety-two percent of respondents used primary therapy or monotherapy with topical medications, including 45% in linear morphea of the limbs and 37% in linear morphea of the head or neck. High-potency topical corticosteroids were most commonly used (80%), although respondents did not agree on specific regimens. Sixteen different treatment regimens were selected as first-line therapy for one case scenario of active disease.

CONCLUSION

The survey found large variation in how pediatric dermatologists treat pediatric morphea. Consensus treatment guidelines developed by pediatric dermatologists and pediatric rheumatologists are urgently needed regarding the efficacy of therapies for pediatric morphea. Prospective studies of treatment efficacy in pediatric morphea are urgently needed as well.

Evaluation of Serum Vitamin D Levels in Patients with Systemic Sclerosis and Healthy Controls: Results of a Pilot Study

Background

The anti-inflammatory, immunomodulatory, and anti-proliferative effects of vitamin D in pathogenesis of autoimmune diseases have been highlighted in recent years but implications of vitamin D deficiency in systemic sclerosis (SSc) remain understudied.

Objectives

To evaluate serum vitamin D levels in SSc patients and matched controls.

Materials and Methods

Serum vitamin D levels were estimated in 38 (M:F 5:33) patients aged 23-70 years of untreated SSc and age and gender matched healthy controls. Clinical and investigative evaluation for skin sclerosis by modified Rodnan skin score (mRSS), presence of digital ulcers, Raynaud's phenomenon, type of auto-antibodies, systemic involvement, and serum vitamin D levels were performed. Serum vitamin D levels were defined as normal (30-100 ng/ml), insufficient (10-30 ng/ml), and deficient (<10 ng/ml).

Results

Serum vitamin D levels (median ± IQR) were 19.5 ± 77.8 ng/ml in 38 patients and 100 ± 31.3 ng/ml in controls each. Vitamin D deficiency in 13 (34.2%) and insufficiency in 10 (26.3%) patients were identified. Only 2 (5.3%) controls had vitamin D insufficiency and the difference was statistically significant (P = 0.001). An inverse relationship was observed between mRSS and serum vitamin D levels.

Conclusions

Patients with SSc have significantly lower serum vitamin D levels than healthy controls. Serum vitamin D levels do not correlate well with age, gender, disease duration or its variants, type of auto antibodies, presence of digital ulceration, or systemic involvement but has inverse correlation with skin sclerosis. Better-designed studies will perhaps resolve issues of potential benefits of vitamin D supplementation in modification of disease activity or severity in SSc.

European Dermatology Forum S1-guideline on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: localized scleroderma, systemic sclerosis and overlap syndromes

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present guideline focuses on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, current strategies in the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this guideline provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes of systemic sclerosis with diseases of the rheumatological spectrum.

Morphea and Eosinophilic Fasciitis: An Update

Morphea, also known as localized scleroderma, encompasses a group of idiopathic sclerotic skin diseases. The spectrum ranges from relatively mild phenotypes, which generally cause few problems besides local discomfort and visible disfigurement, to subtypes with severe complications such as joint contractures and limb length discrepancies. Eosinophilic fasciitis (EF, Shulman syndrome) is often regarded as belonging to the severe end of the morphea spectrum. The exact driving mechanisms behind morphea and EF pathogenesis remain to be elucidated. However, extensive extracellular matrix formation and autoimmune dysfunction are thought to be key pathogenic processes. Likewise, these processes are considered essential in systemic sclerosis (SSc) pathogenesis. In addition, similarities in clinical presentation between morphea and SSc have led to many theories about their relatedness. Importantly, morphea may be differentiated from SSc based on absence of sclerodactyly, Raynaud’s phenomenon, and nailfold capillary changes. The diagnosis of morphea is often based on characteristic clinical findings. Histopathological evaluation of skin biopsies and laboratory tests are not necessary in the majority of morphea cases. However, full-thickness skin biopsies, containing fascia and muscle tissue, are required for the diagnosis of EF. Monitoring of disease activity and damage, especially of subcutaneous involvement, is one of the most challenging aspects of morphea care. Therefore, data harmonization is crucial for optimizing standard care and for comparability of study results. Recently, the localized scleroderma cutaneous assessment tool (LoSCAT) has been developed and validated for morphea. The LoSCAT is currently the most widely reported outcome measure for morphea. Care providers should take disease subtype, degree of activity, depth of involvement, and quality-of-life impairments into account when initiating treatment. In most patients with circumscribed superficial subtypes, treatment with topical therapies suffices. In more widespread disease, UVA1 phototherapy or systemic treatment with methotrexate (MTX), with or without a systemic corticosteroid combination, should be initiated. Disappointingly, few alternatives for MTX have been described and additional research is still needed to optimize treatment for these debilitating conditions. In this review, we present a state-of-the-art flow chart that guides care providers in the treatment of morphea and EF.

Thrombocytopenia Associated with Localized Scleroderma: Report of Four Pediatric Cases and Review of the Literature

We report on four children with localized scleroderma (morphea) and thrombocytopenia. All four had the en coup de sabre subtype of morphea and had varying degrees of thrombocytopenia (8 × 10⁹ /L to 120 × 10⁹ /L). None of them had major bleeding manifestations, and thrombocytopenia resolved with treatment of morphea. (One patient was also given an injection of anti-D immunoglobulin.) We propose that thrombocytopenia associated with localized scleroderma is usually benign and requires no specific therapy.

Morphea - selected local treatment methods and their effectiveness

Localised scleroderma is an uncommon connective tissue disease of multifactorial aetiology occurring in the paediatric and adult population. It is relatively difficult to conduct any research on the subject of this disease entity treatment due to the low number of patients suffering from morphea, a tendency of the disease to remit spontaneously, and not yet well recognised aetiology. Hence, there has been developed no causal treatment of well-proven effectiveness, and schedules of symptomatic therapy are not yet clearly determined. The paper depicts most widely used topical treatment methods in morphea therapy, which due to minor risk of systemic adverse effects seem to be a beneficial therapeutic alternative. The main aim of this article was to analyse different topical treatment options used in localised scleroderma therapy and to indicate the most appropriate, safe, and effective one.

German guidelines for the diagnosis and therapy of localized scleroderma

Localized scleroderma designates a heterogeneous group of sclerotic skin disorders. Depending on the subtype, severity, and site affected, adjacent structures such as adipose tissue, muscles, joints, and bones may be involved. This is an update of the existing German AWMF (Association of the Scientific Medical Societies in Germany) guidelines (classification: S2k). These guidelines provide an overview of the definition, epidemiology, classification, pathogenesis, laboratory workup, histopathology, clinical scoring systems, as well as imaging and device-based workup of localized scleroderma. Moreover, consensus-based recommendations are given on the management of localized scleroderma depending on its clinical subtype. Treatment recommendations are presented in a therapeutic algorithm. No financial support was given by any pharmaceutical company. The guidelines are valid until July 2019.

Nonpsoriatic Uses of Calcipotriol

Background:

Calcipotriol is a synthetic vitamin D3 analog that binds to vitamin D receptors in epidermal cells. In vitro studies have shown that calcipotriol stimulates terminal cell differentiation and has antiproliferative effects. In vivo, calcipotriol has been shown to reduce the number of cycling epidermal cells. Calcipotriol also has less effect on calcium metabolism than calcitriol, which is the natural, bioactive, 1,25-dihydroxyvitamin D3.

Objective:

These properties make calcipotriol an ideal candidate for the topical treatment of hyperproliferative skin disorders. While it has been approved for topical use in psoriasis, its potential for use in other dermatological disorders has not yet been fully investigated.

Conclusion:

This survey of the literature suggests that calcipotriol may show promise in the treatment of other conditions involving abnormal keratinization and hyperproliferation of epidermal cells. While some of these disorders are rare, and therefore difficult to study, further study into the nonpsoriatic uses of calcipotriol may be rewarding.

Localized scleroderma: a review

Localized scleroderma (LoS) comprises a heterogeneous spectrum of fibrotic diseases that primarily affect the skin with inflammation and skin thickening. The extent of skin involvement and manifestation at extra-cutaneous structures characterizes the specific subset. Fat tissue, fascia, and sometimes muscle, and bones might be involved, and in rare cases the central nervous or ocular system.

A worldwide accepted classification system for LoS is still lacking. The latest guidelines have proposed a distinction of limited, generalized, linear, deep, and mixed types. The exact pathophysiology of LoS is not fully understood yet, but it is thought that an externally triggered release of pro-inflammatory cytokines leads to a dysregulation of the connective tissue metabolism.

LoS is diagnosed according to typical clinical features. Further diagnostic procedures are helpful to characterize the subtype and to define the extent of inflammation and fibrosis.

Due to the heterogeneity of LoS, therapeutic strategies should always be selected depending on the respective subtype. The stage of tissue inflammation and sclerosis has to be considered. Treatment options such as topical corticosteroids, calcipotriol, and calcineurin inhibitors as well as phototherapy are well established. In subsets with severe wide-spread skin manifestation and/or extra-cutaneous involvement, methotrexate monotherapy or a combination of methotrexate and systemic corticosteroids need to be considered. Physical treatment should always be added to the topical and systemic treatment to prevent significant disabilities due to LoS. This article provides an updated review on the epidemiology, pathophysiology, clinical classification and treatment options for patients suffering from LoS.

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.

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.

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.

Management of Systemic Sclerosis-Related Skin Disease: A Review of Existing and Experimental Therapeutic Approaches

The skin is the most common organ system involved in patients with systemic sclerosis (SSc). Nearly all patients experience cutaneous symptoms, including sclerosis, Raynaud's phenomenon, digital ulcers, telangiectasias, and calcinosis. In addition to posing functional challenges, cutaneous symptoms are often a major cause of pain, psychological distress, and body image dissatisfaction. The present article reviews the main features of SSc-related cutaneous manifestations and highlights an evidence-based treatment approach for treating each manifestation. This article also describes novel treatment approaches and opportunities for further research in managing this important clinical dimension of SSc.

A vitamin D analog inhibits Th2 cytokine- and TGFβ -induced periostin production in fibroblasts: a potential role for vitamin D in skin sclerosis

Scleroderma is an autoimmune disease characterized by extracellular matrix deposition and inflammation. Topical vitamin D analogs have been reported as effective treatments for scleroderma. We previously reported that a matricellular protein, periostin (POSTN), contributes to pathogenesis of scleroderma as POSTN knockout mice were resistant to bleomycin (BLM)-induced scleroderma. We investigated whether a vitamin D analog affects the expression of POSTN in dermal fibroblasts and in a BLM-induced scleroderma model. The vitamin D analog, maxacalcitol (22-oxacalcitriol [OCT]), was applied to dermal fibroblasts and POSTN expression was measured. The effect of OCT on Th2 cytokine- and TGFβ-induced POTSN and Collagen 1 α 1 (Col1A1) expression was also assessed. In vivo, OCT was administered to BLM-induced scleroderma model and outcomes were determined by dermal thickness, collagen density and POSTN expression. Treatment with OCT significantly decreased POSTN expression in dermal fibroblasts. Th2 cytokine- and TGFβ-induced expression of POSTN and Col1A1 was also suppressed by OCT. In vivo, OCT administration decreased the density of collagen bundles and POSTN expression in a BLM-induced scleroderma model. In addition to the previously reported immunosuppressive effect, the vitamin D analog OCT might be effective to treat scleroderma, in part through inhibition of Th2 cytokine- and TGFβ-induced POSTN expression.

Off-label uses of topical vitamin D in dermatology: a systematic review

BACKGROUND

Topical vitamin D is approved by the US Food and Drug Administration for the treatment of psoriasis but is also used off-label in the treatment of a variety of cutaneous diseases despite a lack of evidence-based guidelines.

OBJECTIVE

The objective of this study was to provide evidence-based clinical guidelines for the off-label use of topical vitamin D in the treatment of dermatologic disease.

METHODS

A systematic literature review was conducted via the MEDLINE, Embase, and CENTRAL databases for off-label uses of topical vitamin D analogues in the treatment of dermatologic disease other than psoriasis. The data were synthesized, and evidence-based recommendations were rendered according to the highest level of evidence available.

RESULTS

A total of 165 articles met the inclusion criteria. A moderate to strong recommendation was given for the use of topical vitamin D in combination with corticosteroids and phototherapy in vitiligo and as monotherapy for various ichthyoses, morphea, pityriasis alba, prurigo nodularis, and polymorphous light eruption. There is evidence showing that topical vitamin D is ineffective in the treatment of actinic keratosis, seborrheic keratosis, lichen planus, seborrheic dermatitis, alopecia areata, chemotherapy-induced alopecia, and hypertrophic scars.

CONCLUSION

Topical vitamin D analogues have an important role in the off-label treatment of dermatologic disease, but higher quality studies are still required.

Diagnosis and management of morphea and lichen sclerosus and atrophicus in children

Morphea (localized scleroderma) is a rare fibrosing disorder of the skin and underlying tissues characterized by skin thickening and hardening due to increased collagen deposition. The significance of the disease depends on the extent of the lesions, potential for functional disability or cosmetic disfigurement, and presence or absence of extracutaneous manifestations. Treatment is tailored; circumscribed forms may require only topical treatment, while forms causing functional impairment or severe cosmetic change may require systemic treatment. Although localized scleroderma has a good prognosis, some clinical subtypes can be deforming and irreversibly disabling, especially when affecting the extremities or the face.

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.
