An evaluation of long-term outcomes in adults with pediatric-onset morphea

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.

Novel multispectral imaging to predict disease progression in pediatric morphea

BACKGROUND

Morphea, or localized scleroderma, is an inflammatory, fibrosing skin disorder that can be progressive and debilitating. Infrared thermography frequently has false positive results. The aim of this study was to assess the ability of multispectral imaging to predict disease progression in children with morphea.

METHODS

Children with morphea were recruited between 2016 and 2022. Multispectral images of affected and matched contralateral unaffected sites were obtained using the Antera™ 3D camera. Clinical assessment was performed using the Localized Scleroderma Assessment Tool (LoSCAT). Children were followed up every 3 months for imaging and clinical review. The main outcome measurement was correlation of hemoglobin gradient between affected and matched contralateral unaffected tissue and progression.

RESULTS

Of 17 children, the average age was 12 years (range 6-18 years); most were female (76.5%) and white (94.1%). Nearly two-thirds (64.7%) had linear morphea, 35.2% had plaque morphea; 58.8% had been treated with systemic agents. The average LoSCAT score was 20.6 (range 5-73). The average hemoglobin gradient between affected and matched contralateral unaffected skin was four times higher in those who had progression (average differential 0.3, range 0.1-0.4) compared to those who did not (average differential 0.08, range 0.02-0.15). Using a cut off of a 0.18 hemoglobin gradient between affected and unaffected skin, the sensitivity of multispectral imaging for detecting progression in pediatric morphea is 90% with specificity of 100%.

CONCLUSIONS

Multispectral imaging is a novel assessment tool with promising accuracy in predicting progression as an adjunct to clinical assessment in pediatric morphea. Further research should examine its performance against thermography.

A Comparison of Clinical, Demographic and Treatment Characteristics of Pediatric-Onset and Adult-Onset Patients Diagnosed With Localized Scleroderma

INTRODUCTION

Morphea localized scleroderma (LS) is a rare skin disease with unknown pathogenesis, which causes sclerosis of the dermis and subcutaneous tissue.

OBJECTIVES

It was aimed to compare the characteristics of patients with pediatric and adult-onset morphea.

METHODS

A retrospective analysis was performed on the records of 183 adult morphea patients. The demographics, clinical and laboratory characteristics, and treatment options of the patients were recorded. Adult patients with morphea over the age of 18 were divided into two groups according to the age of onset and compared.

RESULTS

Twenty-two percent (N = 41) of the patients had pediatric-onset morphea (POLS) and 77.6% (n=142) had adult-onset morphea (AOLS). While POLS had a higher head-neck involvement, AOLS had a higher breast involvement (P < 0.001 and P = 0.043). Patients with linear morphea were younger, and more frequently had at least one laboratory anomaly (P = 0.016 versus 0.024). Anti-dsDNA positivity and low hemoglobin (Hb) were observed more frequently in patients with breast involvement. Patients with inguinal involvement, on the other hand, had lower Hb and a higher rate of diabetes, and those patients were older (P = 0.042, 0.040, and 0.012, respectively).

CONCLUSIONS

Clinical characteristics and accompanying laboratory anomalies of the patients with morphea depend on the age of onset, involvement areas and the types of morphea, having such data readily available should guide the holistic approach for, and the monitoring process of, the disease.

Use of 3-Dimensional Stereophotogrammetry to Detect Disease Progression in Craniofacial Morphea

Importance

Objectively determining disease progression in craniofacial morphea (CM) is challenging, as clinical findings of disease activity are often lacking.

Objective

To evaluate the utility of 3-dimensional (3D) stereophotogrammetry in detecting disease progression in CM over time.

Design, Setting, and Participants

This prospective cohort study included 27 pediatric and adult patients with CM from 2 hospitals in Boston (Boston Children's Hospital and Brigham & Women's Hospital) consecutively enrolled from April 1, 2019, to March 1, 2023. Review of 3D stereophotogrammetry images and data analysis occurred from March 1 to April 1, 2023.

Main Outcomes and Measures

Clinical and 3D stereophotogrammetry assessments were performed at 2- to 12-month intervals, depending on the clinical context. The 3D stereophotogrammetry images were then qualitatively rated as demonstrating no progression or definitive progression by an expert (board-certified plastic craniofacial surgeon) and nonexpert (board-certified dermatologist) in 3D stereophotogrammetry. In addition, κ coefficients were calculated for interrater reliability.

Results

Of 27 patients with CM (19 female; median age, 14 [range, 5-40] years) and 3D stereophotogrammetry images obtained from a minimum of 2 time points (median, 4 [range, 2-10] images) spaced a median of 3 (range, 2-12) months apart, 10 experienced progression of their disease based on clinical assessments performed during the study period. In all cases in which clinical progression was favored, blinded qualitative assessment of 3D stereophotogrammetry images also favored progression with substantial interrater reliability (κ = 0.80 [95% CI, 0.61-0.99]). Furthermore, review of 3D stereophotogrammetry detected occult progression of asymmetry not noted on clinical examination in 3 additional patients.

Conclusions and Relevance

In this prospective cohort study, blinded assessment of sequential 3D stereophotogrammetry images in patients with CM not only corroborated clinical assessment of disease progression but also detected occult progression of facial asymmetry not appreciable on clinical examination alone. Therefore, 3D stereophotogrammetry may serve as a useful adjunct to clinical examination of patients with CM over time. Future investigations are warranted to validate 3D stereophotogrammetry as an outcome measure in CM.

Disturbances of the stomatognathic system and possibilities of its correction in patients with craniofacial morphea

Morphea en coup de sabre and progressive hemifacial atrophy are extremely rare connective tissue disorders causing facial deformity. In extreme cases, morphological disorders are accompanied by symptoms of a clear impairment of the stomatognathic system. The aetiology of the above-mentioned diseases is still unknown. Properly planned therapy in the field of maxillofacial orthopaedics makes it possible to correct the asymmetric pattern of hard tissue growth and thus enable rehabilitation. The task of augmentation techniques is the volumetric supplementation of tissue defects resulting from atrophic processes. The degree of destruction and the extent of changes determine the method of correction. Mild and moderate defects are treated mainly with biomaterials and autologous adipose tissue. The severe course of hemifacial atrophy and morphea en coup de sabre and the associated significant tissue atrophy necessitate the search for more complex methods of treatment. In this paper, we summarize the disturbances of the stomatognathic system in patients with craniofacial morphea, together with an analysis of current treatment options.

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.

Measuring asymmetry in facial morphea via 3-dimensional stereophotogrammetry

BACKGROUND

Objectively determining tissue loss in craniofacial morphea is challenging. However, 3-dimensional (3D) stereophotogrammetry is a noninvasive modality that may be a useful adjunct.

OBJECTIVE

To prospectively evaluate 3D stereophotogrammetry in the assessment of craniofacial linear morphea.

METHODS

Participants underwent clinical, quality-of-life, and 3D-stereophotogrammetry assessments. Traditional photographs and 3D-stereophotogrammetry images were rated as mild, moderate, or severe by 2 experts and 2 nonexperts. In addition, interrater and intrarater reliability (on delayed rescoring) were calculated.

RESULTS

Of 23 patients with craniofacial morphea, 3D stereophotogrammetry detected pathologic asymmetry in 14 (20.6%) patients. Providers rated patients as more severely affected when using 3D stereophotogrammetry versus when using traditional photographs (19% severe on 3D stereophotogrammetry vs 0% severe on traditional photographs, P = .004). Qualitative ratings of both traditional and 3D images showed high inter- and intrarater reliability between experts and nonexperts alike. Physicians' Global Assessment of Damage scores correlated with mouth asymmetry (P = .0021), cheek asymmetry (P = .04), and 3D-stereophotogrammetry ratings (median, mild: 27.5 vs moderate: 46.5 vs severe: 64, P = .0152). Lower face asymmetry correlated with worse quality-of-life scores (P = .013).

LIMITATIONS

Small sample size and cross-sectional design.

CONCLUSION

3D stereophotogrammetry can reliably detect and quantify asymmetry in craniofacial morphea with greater sensitivity than that observed with traditional assessment alone. 3D stereophotogrammetry may be a useful adjunct to clinical examination.

Face Lesions in En Coup De Sabre Scleroderma in Children: Modern Treatment and Outcomes Improvement

Localized scleroderma (LS) is an inflammatory sclerosing disease of the skin and subcutaneous tissues associated with its atrophy. Commonly, LS is a benign self-limited disease, although, the chronic form of this disease is recurrent. Particular attention is paid to the research of treatments methods that could eliminate not only immune-mediated mechanisms, but also its outcomes (such as gross cosmetic defects on the face), which negatively affect child’s physical and psycho-emotional development. Recently, fat transplantation efficacy has been studied as it can restore the volume and improve skin quality. This article presents the results of such surgery in a patient (15 years old) with linear form of LS.

Mycophenolate mofetil for methotrexate-resistant juvenile localized scleroderma

OBJECTIVES

To investigate safety and efficacy of MMF in patients with severe or MTX-refractory juvenile localized scleroderma.

METHODS

Consecutive juvenile localized scleroderma patients undergoing systemic treatment were included in a retrospective longitudinal study. Patients treated with MMF because they were refractory or intolerant to MTX (MMF-group) were compared with responders to MTX (MTX-group). Disease activity was assessed by Localized Scleroderma Cutaneous Assessment Tool and thermography. Disease course was established on the number of relapses and treatment changes. Relapse-free survival was examined by Kaplan-Meier analysis.

RESULTS

MMF and MTX groups included 22 and 47 patients, respectively. No significant difference in demographics, follow-up duration and treatment before diagnosis was observed between groups. The most represented clinical subtypes in the MMF-group were pansclerotic morphea and mixed subtype (P = 0.008 and P = 0.029, respectively), and linear scleroderma of the face in the MTX-group (P = 0.048). MMF was started because of MTX resistance (18 patients), relapse during MTX tapering/withdrawal (3 patients) and anaphylaxis to MTX (1 patient). After mean 9.4 years of follow-up, 90.9% of patients on MMF and 100% of those on MTX had inactive disease. No significant difference in relapse-free survival between the groups was found (P = 0.066, log-rank test), although MMF likely induced more persistent remission. MMF was well tolerated and combination of MMF and MTX did not increase its efficacy.

CONCLUSION

The present study adds strong evidence on the efficacy and tolerance of MMF in severe and/or MTX-refractory juvenile localized scleroderma. Further controlled studies are needed to prove its efficacy as first line treatment.

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.

Comparing paediatric- and adult-onset linear morphoea in a large tertiary-referral scleroderma centre

BACKGROUND

Linear morphoea is a severe morphoea subtype associated with extracutaneous manifestations, potentially permanent disfigurement and functional impairment. Linear morphoea is more prevalent in paediatric patients, and knowledge of disease in adults is limited. The objective of this study was to compare paediatric- and adult-onset linear morphoea, in an exclusively adult population.

METHODOLOGY

This was a retrospective cohort study of adult patients with linear morphoea seen over a 3-year period at a single-site adult tertiary-referral Connective Tissue Disease centre. Clinical markers of disease severity and course, including anatomical distribution, extracutaneous manifestations, cutaneous symptoms, associated autoimmunity, inflammatory blood parameters, Dermatology Life Quality Index scores, treatment requirements and modified Localised Scleroderma Activity Tool were assessed and compared in paediatric- and adult-onset linear morphoea.

RESULTS

Of 298 patients with morphoea seen during the study period, 135 had linear morphoea and 133 were included in the study. Most were female (78.9%), the mean age was 36.5 years and almost half (43.6%) had adult-onset disease. Disease was similarly severe between groups with regard to anatomical distribution, cutaneous symptoms (n = 89, 66.9%), extracutaneous manifestations (n = 76, 57.1%), antinuclear antibody-positivity (n = 40, 40.4%), raised erythrocyte sedimentation rate (n = 27, 25.0%) and associated autoimmune diagnoses (n = 15, 11.3%). Prescribed treatments were similar between groups; 73.7% receiving methotrexate and almost one-third (32.3%) requiring more than one steroid-sparing agent. Those with paediatric-onset had more disease-related damage, with a mean modified Localised Scleroderma Skin Damage Index score of 19.5 (95% confidence interval: 17.0-22.0) versus 8.1 (95% confidence interval: 4.4-11.8; p < 0.001). Significantly more patients with adult-onset linear morphoea had quiescent disease (p = 0.0332), and even after correcting for disease duration, paediatric-onset patients still had 2.6 times greater odds of active disease (odds ratio = 2.59, 95% confidence interval: 0.9-7.6; p = 0.083).

CONCLUSION

Linear morphoea in adults can be a severe disease with extracutaneous, autoimmune and systemic features. Adults with paediatric-onset disease appear to have more severe cumulative damage, greater functional impairment and ongoing disease activity. This patient subgroup may require particularly close monitoring and more aggressive therapy.

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.

Health-related quality of life and its influencing factors in adult patients with localized scleroderma - a cross-sectional study

Background

Localized Scleroderma (LoS) is an autoimmune connective tissue disease that affects skin and less commonly subcutaneous tissues. The illness occurs in children and adults, and may have a serious impact on health-related quality of life (HRQoL). The goal of this study was to explore what factors might deteriorate scores on HRQoL measures in adult LoS patients.

Methods

Detailed information on the demographic and clinical features of LoS patients was collected. The HRQoL was assessed using Skindex-29 and Short form 36 (SF-36) questionnaires.

Results

Thirty three women and seven men with LoS were enrolled. Female gender negatively influenced scores for the emotion subscale of Skindex-29. Multiple-factor linear regression analysis confirmed, as with single-factor analysis, that the causes of low SF-36 physical component score (PCS) were subjective symptoms (pruritus, pain, paresthesia), musculoskeletal manifestations and older age at the time of survey, while rural area of residence negatively affected the SF-36 mental component score. Additionally, single-factor analysis showed that the SF-36 PCS was related to the LoS cutaneous assessment tool (LoSCAT) summary score.

Conclusions

Apart from a clinical presentations, sociodemographic characteristics, including older age, female gender and living conditions, may impair HRQoL of LoS patients. Further studies that will examine the role of these factors for physical and mental functioning of adults with LoS are needed.

Quality of Life in Patients with Morphea: A Cross-Sectional Study and a Review of the Current Literature

Objective

The aim of the study was to evaluate QoL in patients suffering from morphea. Material and Methods. Sixty-five patients with morphea were recruited into this cross-sectional, prospective parallel study. QoL among adult patients was assessed with the Dermatology Life Quality Index (DLQI) and Euro-QoL-5D questionnaire; patients aged <17 years used the Children's Dermatology Life Quality Index (CDLQI). The severity of morphea was assessed using the Localized Scleroderma Cutaneous Assessment Tool. The results of QoL and its association with disease severity were compared between patients with various morphea subtypes.

Results

The mean DLQI scoring was 3.8 ± 4.1 points and the CDLQI was 2.3 ± 3.0. The mean value of Visual Analogue Scale thermometer (EQ VAS) was 66.9 ± 17.5 points. The disease activity of morphea based on mLoSSI correlated significantly with QoL impairment according to the DLQI (R = 0.41, p = 0.001). No significant correlation was observed between morphea-induced damage and QoL (p = 0.99).

Conclusions

Evaluation of QoL in patients with morphea is still challenging due to lack of good assessment tools dedicated specifically for morphea patients. In general, QoL in morphea patients is significantly correlated with the disease activity, but not with disease-induced skin damage.

A novel patient-reported outcome for paediatric localized scleroderma: a qualitative assessment of content validity

BACKGROUND

According to current standards, no existing patient-reported outcome (PRO) measures have high-quality validity evidence for use with individuals diagnosed with paediatric localized scleroderma (LS). This severely hinders patient-centred LS-focused research, including much needed clinical trials.

OBJECTIVES

To develop a valid health-related quality of life measure for individuals with paediatric LS and to qualitatively evaluate its content validity using a patient-centred approach.

METHODS

Previously collected qualitative data from youth with LS and their caregivers was used to develop items. The resulting item set was administered in a clinical setting to participants aged 8-18 years old. Cognitive interviews were used to evaluate time to survey completion, readability/understanding of the items, appropriateness of the recall period and construct representation.

RESULTS

Seventeen children and adolescents with LS participated in the study. Interviews supported readability, understanding of the items and appropriateness of the recall period in individuals > 10 years old. Revisions were made to simplify the instructions and to be more inclusive of different subtypes of LS. Three items were added to improve content representation.

CONCLUSIONS

Content validity was supported by the patient-centred development process of the outcome measure and via direct feedback from individuals with LS and their families. Although an important first step, the resulting PRO, termed the Localized Scleroderma Quality of Life Instrument, should be further evaluated in a larger sample before being implemented. What's already known about this topic? No current health-related quality of life (HRQoL) measures have been created using direct input from children and adolescents with localized scleroderma (LS). When compared with qualitative reports of HRQoL impact in youth with all LS subtypes, no existing patient-reported outcome (PRO) measures have appropriate content validity for individuals with paediatric LS. What does this study add? This study proposes a novel LS-specific PRO and is the first qualitative assessment of content validity for any PRO measure in this population. Results from cognitive interviews with children and adolescents support the content validity of the newly developed item set and its ability to capture HRQoL impact in a clinical context. What are the clinical implications of this work? Incorporating a content-valid PRO of HRQoL impact into clinical practice would allow for the valid, ongoing capture of patient experience in LS. Although content validity is an important and necessary step in the process of evaluating validity, items within this novel measure will undergo additional psychometric evaluation before implementation in research and clinical settings.

Initial Results from a Pilot Comparative Effectiveness Study of 3 Methotrexate-based Consensus Treatment Plans for Juvenile Localized Scleroderma

Objective.

To perform a comparative effectiveness feasibility study in juvenile localized scleroderma (LS), using standardized treatment regimens (consensus treatment plans; CTP).

Methods.

A prospective, multicenter 1-year pilot observational cohort study was performed by Childhood Arthritis and Rheumatology Research Alliance (CARRA) LS workgroup members. Patients with active, moderate to severe juvenile LS were treated with one of 3 CTP: methotrexate alone, or in combination with intravenous (30 mg/kg/dose for 3 mos) or oral corticosteroids (2 mg/kg/day tapered by 48 weeks).

Results.

Fifty patients, with demographics typical for juvenile LS, were enrolled, and 44 (88%) completed the study. Most had extracutaneous involvement. Patients improved in all 3 CTP, with > 75% having a major or moderate level of improvement compared to baseline. Damage accrued in some patients. Major deviations from prescribed regimen resulted from medication intolerance (n = 6; 14%) or treatment failure (n = 11; 25%); failures occurred in all 3 CTP. Significant responses to treatment were demonstrated by LS skin scoring measures and overall physician assessments, with differences in response level identified in some patient subsets. Response differences were associated with baseline disease activity level, LS subtype, skin disease extent, and extracutaneous involvement.

Conclusion.

This study demonstrates the feasibility of conducting juvenile LS comparative effectiveness studies. The CTP were found to be safe, effective, and tolerable. Our assessments performed well. Because damage is common and may progress despite effective control of activity, we recommend initial treatment efficacy be evaluated primarily by activity measures. Potential confounders for response were identified that warrant further study.

Diagnosis and management of linear scleroderma in children

PURPOSE OF REVIEW

Linear scleroderma is the most common subtype of localized scleroderma (LoS) in children. It can be associated with extracutaneous manifestations and long-term sequelae. Thus, appropriate diagnosis and management are key to improve the prognosis. In this review, we summarize the most relevant recent publications for the diagnosis, evaluation of disease activity and adequate management of patients with linear scleroderma.

RECENT FINDINGS

There are specific clinical features that indicate activity in LoS; dermoscopy and Wood's lamp may be useful. Summarizing, scoring methods seem to provide the most adequate assessment of LoS; but several biomarkers that correlate with activity have been studied: E-selectin and IL-2 receptor, CD34+ dermal dendritic cells and Th/Th1 immunophenotype with decreased T helper (Th2), T regulatory (Tregs), B and natural killer (NK) cells. Recent studies propose hydroxychloroquine monotherapy and tocilizumab as potential therapeutic options.

SUMMARY

Clinical evaluation, both physical exam and history, is the most important aspect in diagnosing and assessing activity of linear scleroderma. Clinical scoring methods may be most useful for evaluation of activity; eventually, other biomarkers could be relevant in clinical practice. For most patients with linear scleroderma, the first choice of treatment is methotrexate, but physical therapy, plastic surgery and/or orthopedic management are key to improve residual limitations and quality of life.

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.

Immunopathogenesis of Pediatric Localized Scleroderma

Localized scleroderma (LS) is a complex disease characterized by a mixture of inflammation and fibrosis of the skin that, especially in the pediatric population, also affects extracutaneous tissues ranging from muscle to the central nervous system. Although developmental origins have been hypothesized, evidence points to LS as a systemic autoimmune disorder, as there is a strong correlation to family history of autoimmune disease, the presence of shared HLA types with rheumatoid arthritis, high frequency of auto-antibodies, and elevated circulating chemokines and cytokines associated with T-helper cell, IFNγ, and other inflammatory pathways. This inflammatory phenotype of the peripheral blood is reflected in the skin via microarray, RNA Sequencing and tissue staining. Research is underway to identify the key players in the pathogenesis of LS, but close approximation of inflammatory lymphocytic and macrophage infiltrate with collagen and fibroblasts deposition supports the notion that LS is a disease of inflammatory driven fibrosis. The immune system is dynamic and undergoes changes during childhood, and we speculate on how the unique features of the immune system in childhood could potentially contribute to some of the differences in LS between children and adults. Interestingly, the immune phenotype in pediatric LS resembles to some extent the healthy adult cellular phenotype, possibly supporting accelerated maturation of the immune system in LS. We discuss future directions in better understanding the pathophysiology of and how to better treat pediatric LS.

Baseline Description of the Juvenile Localized Scleroderma Subgroup From the Childhood Arthritis and Rheumatology Research Alliance Legacy Registry

Objective

Localized scleroderma (LS) is a chronic inflammatory and fibrosing skin disorder. We present baseline data on the juvenile LS (jLS) cohort from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry, a multicenter observational registry of pediatric rheumatologic disorders.

Methods

This is a cross-sectional analysis of children with jLS enrolled in the CARRA Legacy Registry between May 2010 and April 2014. Descriptive statistics were used for demographic, clinical, and laboratory features. Data analysis included two-sample t test, χ² test, Fisher's exact test, linear/logistic regression, and analysis of variance.

Results

Of 381 children with jLS, 76% were female and 80% Caucasian. Mean onset age was 8.2 years, with 17% having a 2-year or greater delay to first pediatric rheumatology (PRH) visit. Linear scleroderma was the most common subtype (54%). Antinuclear antibody (ANA) positivity was associated with joint contracture (P = 0.04), muscle atrophy (P = 0.014), and extremity shortening (P = 0.007). Elevated aldolase was associated with joint contracture (P = 0.008) and elevated creatine kinase (CK) with muscle atrophy (P = 0.028) and extremity shortening (P = 0.016). Children with functional limitation (27%) had earlier first PRH visit compared with those without (P = 0.01). Poorer function correlated with muscle atrophy, joint contracture, and extremity shortening (P < 0.001). Methotrexate (97%) and corticosteroids (68%) were the most common medications used.

Conclusion

Children with jLS without joint limitation are referred later, highlighting the insidious onset and need for educating referring providers. Poorer function correlated with muscle atrophy, joint contracture, and limb shortening. ANA positivity and elevated CK or aldolase were associated with muscle atrophy, joint contracture, and/or limb shortening, suggesting predictors of muscle involvement.

Prediction of disease relapse in a cohort of paediatric patients with localized scleroderma

BACKGROUND

Localized scleroderma (LS) is an autoimmune condition of the skin and underlying tissue. Active or recurring disease can lead to cumulative tissue damage, especially in paediatric-onset disease.

OBJECTIVES

To highlight the rate of relapse of LS activity in a cohort of paediatric patients and to evaluate for potential clinical and laboratory predictors of disease relapse.

METHODS

Clinical and laboratory data were gathered prospectively. Patients were categorized as experiencing relapse or not, and clinical and laboratory parameters were compared. A logistic regression was fit to predict odds of relapse while controlling for multiple predictors. A subgroup of patients was also evaluated to determine the average time from treatment completion to relapse.

RESULTS

Seventy-seven patients were followed for the identified study duration of > 2 years and had achieved disease remission, with 35 (45%) experiencing LS relapse. Patients who were older at disease onset, antinuclear antibody (ANA) positive and without an extracutaneous manifestation (ECM) were more likely to relapse. All three variables remained significant in the multivariable logistic regression model. Results of the subgroup mirrored the larger sample. The average time between treatment completion and relapse was 21 months.

CONCLUSIONS

Assessment of patients with LS experiencing a relapse of disease activity has shown older age of initial LS onset and ANA positivity to be potential markers for risk of relapse. Patients meeting these parameters may require greater clinical vigilance. The presence of one or more ECM may be protective. Clinicians treating patients with LS should provide significant long-term follow-up to monitor for relapse.

The correlation between serum E-selectin levels and soluble interleukin-2 receptors with relation to disease activity in localized scleroderma

Introduction

Scleroderma is a chronic connective tissue disease resulting in fibrosis.

Aim

The aim of the study was to determine the connection between sE-selectin and sIL-2R and the severity of skin lesions in various subtypes of LoS. Evaluation of disease severity, the location of skin lesions, the duration of symptoms and disease activity were assessed in relation to the three different LoS subtypes in patients with localized scleroderma.

Material and methods

The study included 42 patients with localized scleroderma and the control group consisted of 41 healthy subjects. All patients in the LoS study group had a confirmed diagnosis via skin biopsy and underwent serology testing for sE-selectin and sIL-2R concentrations by enzyme-linked immunosorbent assay (ELISA).

Results

Significantly higher levels of sE-selectin and sIL-2R were observed in the LoS study group when compared with the control group (p < 0.001). The analysis showed a result close to statistical significance (p = 0.058) between sE-selectin concentration during the time of active disease in the LoS study group. The highest concentrations of sE-selectin and sIL-2R were observed in patients with the generalized subtype of LoS. A positive, statistically significant, curvilinear relationship was shown amid the modified Localized Skin Severity Index (mLoSSI) and sE-selectin and sIL-2R concentrations in the LoS study group.

Conclusions

Concentrations of the circulating form of sE-selectin appear to be an adequate marker of the endothelial function, positively correlating with the severity of the disease. The proven correlation of sIL-2R concentrations with the severity of the disease indicates that it is a valuable prognostic factor for predicting the impending course of the disease.

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.

Scleroderma in Children and Adolescents: Localized Scleroderma and Systemic Sclerosis

Scleroderma is a rare disease that has two main forms: localized scleroderma (LS) and systemic sclerosis (SSc). Both are chronic diseases, can present in different patterns (subtypes), and are associated with extracutaneous involvement in pediatric patients. Morbidity and mortality is much worse for juvenile SSc with patients at risk for life-threatening lung, heart, and other visceral organ fibrosis and vasculopathy. Mortality is extremely rare in juvenile LS, but morbidity is common, with patients at risk for severe disfigurement and functional impairment. Scleroderma treatment is directed towards controlling inflammation and managing specific problems. Early diagnosis can greatly improve outcome.

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.

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.

Histopathological changes in morphea and their clinical correlates: Results from the Morphea in Adults and Children Cohort V

BACKGROUND

Histopathological features in morphea (localized scleroderma) and their clinical correlates are poorly described.

OBJECTIVE

We sought to systematically describe histologic changes of morphea in a large, well-annotated cohort and determine the association between histopathology and clinical features.

METHODS

This was a cross-sectional study of 83 patients enrolled in the Morphea in Adults and Children cohort. The main outcome measure was the association of microanatomical location and degree of sclerosis and inflammation seen on histologic samples with patient-reported symptoms and physician-based measures of severity.

RESULTS

Pattern of sclerosis was associated with morphea subtype, the presence of patient-reported symptoms, and functional limitation. A bottom-heavy pattern of sclerosis was associated with pain and tightness (P = .0039 and .001, respectively). These symptoms were not associated with a top-heavy pattern. Severe inflammation may be associated with pain and functional limitation (P = .073 for both).

LIMITATIONS

Small sample size limits ability to detect associations, particularly in subgroups.

CONCLUSIONS

Histopathological examination of morphea may assist in identifying patients who may require additional monitoring and treatment. Features such as patterns of sclerosis and severity of inflammation should be included in pathology reports to help aid in clinical management.

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.

A Practical Approach to Juvenile Dermatomyositis and Juvenile Scleroderma

Juvenile dermatomyositis and juvenile scleroderma are rare multisystem autoimmune disorders. Although they share some pathognomonic hallmarks with adult onset myositis or scleroderma, there are significant differences in presentation, characteristics and associated features when the diseases present in childhood. In view of this, and the rarity of the conditions, it is important for care to be led by teams with expertise in pediatric rheumatology conditions. Prognosis has improved significantly in the West; likely due to early diagnosis and aggressive treatment with immunosuppressive medications. However, this trend is not replicated in the developing world. Early recognition of these diseases is crucial to achieve rapid and sustained remission and prevent disease or medication associated complications. This article aims to provide a practical overview for recognition, diagnosis and treatment of these conditions.

Rheumatologic Skin Disease

In common rheumatologic diseases skin findings are an important diagnostic clue for astute clinicians. Skin manifestations can help identify systemic disease or may require therapy uniquely targeted at the cutaneous problem. This article discusses 3 common rheumatologic conditions seen in adults by dermatologists: cutaneous lupus, dermatomyositis, and morphea. The focus is on the cutaneous findings and clinical presentation. Some approaches to treatment are explored. Clues to help identify systemic disease are also highlighted.

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.

A Case Report of Successful Treatment of Recalcitrant Childhood Localized Scleroderma with Infliximab and Leflunomide

Herein we report successful treatment of an adolescent Caucasian female with severe progressive localized scleroderma (mixed subtype, including generalized morphea and linear scleroderma of the trunk/limb) using infliximab and leflunomide. The patient demonstrated improvement after the first 9 months of therapy based on her clinical examination, objective measures, and patient and parent global assessments. Infliximab is a potential treatment option for pediatric localized scleroderma patients who have progression of disease or who are unable to tolerate the side effect profile of more standard systemic therapy. Larger longitudinal studies or case series are needed to confirm and further investigate infliximab’s role in localized scleroderma.

Health-related quality of life in morphoea

BACKGROUND

Little is known about the health-related quality of life (HRQoL) of patients with morphoea, and previous studies have yielded conflicting results.

OBJECTIVES

To determine the impact of morphoea on HRQoL, and clinical and demographic correlates of HRQoL in adults.

METHODS

This was a cross-sectional survey (n = 73) of the Morphea in Adults and Children cohort.

RESULTS

Morphoea impairs HRQoL in adults. Patients were most impaired by emotional well-being and concerns that the disease would progress to internal organs. Patients with morphoea had worse skin-specific HRQoL than those with nonmelanoma skin cancer, vitiligo and alopecia (lowest P < 0·01). Participants had significantly worse global HRQoL scores than the general U.S. population for all subscales (all P < 0·01), with the exception of bodily pain. Comorbidity (r = 0·35-0·51, all P < 0·01), and symptoms of pruritus (r = 0·38-0·64, all P < 0·01) and pain (r = 0·46-0·74, all P < 0·01) were associated with impairment in multiple domains of skin-specific and global HRQoL. Physician-based measures of disease severity correlated with patient-reported HRQoL.

CONCLUSIONS

Patients with morphoea experience a negative impact on HRQoL, particularly if symptoms (pruritus and pain) or concerns regarding internal manifestations are present. Providers should be aware of this when evaluating and treating patients.

Delay in Diagnosis of Congenital Linear Scleroderma until Adulthood

Background

Scleroderma encompasses a spectrum of disorders characterized by thickening of the skin and subcutaneous tissue with increased collagen deposition. Linear scleroderma is subdivided into progressive hemifacial atrophy and en coup de sabre subtype.

Objective

We report a case of congenital linear scleroderma identified in an adult, misdiagnosed since birth as birth trauma.

Methods

We completed a review of the literature for similar cases using PubMed and Medline.

Results

This is the first report of congenital linear scleroderma en coup de sabre diagnosed in an adult following an initial misdiagnosis of birth trauma. The sequelae of linear scleroderma can be significant as it can result in growth retardation, muscle atrophy, contractures, limb length discrepancy, and disfigurement.

Conclusions

This report emphasizes the importance of educating practitioners about linear scleroderma. Early recognition is key as a delay in diagnosis can result in potentially preventable, irreversible growth defects and disfigurements.

Comparison of outcomes in adults with pediatric-onset morphea and those with adult-onset morphea: a cross-sectional study from the morphea in adults and children cohort

OBJECTIVE

Few studies have examined outcomes in adults with pediatric-onset morphea. The objective of the present study was to compare clinical outcomes and health-related quality of life (HRQOL) in adults with onset of morphea in childhood to those in patients with adult onset of morphea.

METHODS

Participants in the study were drawn from the Morphea in Adults and Children cohort and included 68 adults with pediatric-onset morphea and 234 patients with adult-onset morphea. Outcome measures included the Localized Scleroderma Cutaneous Assessment Tool (LoSCAT), physical examination findings, and HRQOL questionnaires.

RESULTS

Adults with pediatric-onset morphea were younger, had longer disease duration, and were more likely to have the linear subtype of morphea. Patients with pediatric-onset disease were less likely to have active disease. Among patients with active disease, those with pediatric-onset morphea had less disease activity as measured by the LoSCAT. Patients with pediatric-onset disease had higher severity of disease damage when measured by the physician's global assessment of damage, but had similar levels of disease damage when measured by the Localized Scleroderma Skin Damage Index. Patients with pediatric-onset disease had more favorable HRQOL scores for all measures, all of which were statistically significantly different from those in patients with adult-onset morphea.

CONCLUSION

Adults with pediatric-onset morphea differ from patients with adult-onset disease with respect to disease subtype, severity of disease activity and damage, and levels of HRQOL.

Short- and long-term outcome of linear morphoea in children

BACKGROUND

Linear morphoea (LM) is a rare fibrosing disorder of the limbs or the face that may cause functional disability and severe aesthetic sequelae. Despite a wide range of therapeutics reported for LM, there is currently a lack of consensus on the optimal therapy. Little is known about the long-term outcome of this disease.

OBJECTIVES

To describe the short- and long-term outcome of a large series of patients with LM acquired in childhood.

METHODS

A retrospective chart review of 52 paediatric patients with LM seen in our centre during a 20-year span (1990-2010) and a telephone survey in 2011 to assess the long-term outcome of these patients.

RESULTS

Limbs were affected twice as often as the face, with a higher proportion of female patients. Stabilization was obtained after a mean disease duration of 5·4 years. Patients sometimes experienced long stretches of disease quiescence followed by reactivation; 31% of patients reported active disease after 10 years. All but one patient had aesthetic sequelae, and 38% had functional limitations. The effectiveness of methotrexate and systemic corticosteroids was apparent in the short term.

CONCLUSIONS

LM needs prolonged monitoring as the disease can have very long periods of quiescence followed by reactivation. The combination of methotrexate and systemic corticosteroids was effective in the early stages of the disease but did not seem to prevent long-standing active disease or relapse in the long term.

Correlates of self-reported quality of life in adults and children with morphea

BACKGROUND

Determining a disease's impact on life quality is important in clinical decision making, research, and resource allocation. Determinants of quality of life (QOL) in morphea are poorly understood.

OBJECTIVE

We sought to ascertain demographic and clinical variables correlated with negative impact on self-reported QOL in morphea.

METHODS

We conducted a cross-sectional survey of the Morphea in Adults and Children cohort.

RESULTS

Symptoms (pruritus and pain) and functional impairment were correlated with decreased QOL in children and adults. This was true in both sexes and was independent of subtype and age. Patient-reported QOL correlated with physician-based measures of disease severity in adults, but not in children. Patients with linear and generalized morphea had the greatest impact on QOL.

LIMITATIONS

Small sample size is a limitation.

CONCLUSION

Symptoms and functional impairment were determinants of impaired life quality in both children and adults independent of morphea subtype. These results suggest that clinicians should consider suppressing the accumulation of new lesions (when rapidly accumulating) and symptoms (pain and pruritus) in the treatment of patients with morphea.
