Esophageal abnormalities in juvenile localized scleroderma: is it associated with other extracutaneous manifestations? / Anormalidades esofágicas na esclerodermia localizada juvenil: associação com outras manifestações extracutâneas?

Abstract Objective: To assess esophageal involvement (EI) in juvenile localized scleroderma (JLS) population and the possible association between this gastrointestinal manifestation and demographic data, clinical features, laboratory exams, treatments and outcomes. Methods: For a period of 30 years, 5881 patients with rheumatic diseases were followed in our Pediatric Rheumatology Division. EI was defined by the presence of symptoms (solid/liquid dysphagia, heartburn, esophageal regurgitation, nausea/vomiting and epigastralgia) and confirmed by at least one EI exam abnormality: barium contrast radiography, upper gastrointestinal endoscopy and 24-hour esophageal pH-monitoring. Results: JLS was observed in 56/5881 patients (0.9%), mainly linear morphea subtype. EI was observed in 23/56(41%) of JLS patients. Eight(35%) of 23 EI patients with JLS were symptomatic and presented heartburn(5/8), solid and liquid dysphagia(3/8), nausea and epigastralgia(1/8). The frequency of any cumulative extracutaneous manifestations (calcinosis, arthritis/arthralgia, central nervous system, interstitial pneumonitis, mesangial nephritis and/or arrhythmia) was significantly higher in JLS patients with EI compared to those without this complication (56% vs. 24%, p = 0.024). No differences were evidenced in demographic data, JLS subtypes and in each extracutaneous manifestation in both groups (p > 0.05). The frequency of methotrexate use was significantly higher in JLS patients with EI compared to those without (52% vs. 12%, p = 0.002). Autoantibody profile (antinuclear antibodies, anti-SCL-70, rheumatoid factor, anticentromere, anti-cardiolipin, anti-Ro/SSA and anti-La/SSB) was similar in both groups (p > 0.05). Conclusions: Our study demonstrated that EI was frequently observed in JLS patients, mainly in asymptomatic patients with linear subtype. EI occurred in JLS patients with other extracutaneous manifestations and required methotrexate therapy.

Resumo Objetivo: Avaliar o envolvimento do esôfago (EE) na população com esclerodermia localizada juvenil (ELJ) e a possível associação entre essa manifestação gastrointestinal e dados demográficos, características clínicas, exames laboratoriais, tratamentos e desfechos. Métodos: Durante 31 anos, 5.881 pacientes com doenças reumáticas foram acompanhados em nossa Divisão de Reumatologia Pediátrica. O EE foi definido pela presença de sintomas (disfagia para sólidos/líquidos, azia, regurgitação esofágica, náuseas/vômitos e epigastralgia) e confirmado com pelo menos um exame que revelou EE: radiografia contrastada com bário, endoscopia digestiva alta e pHmetria esofágica de 24 horas. Resultados: Observou-se ELJ em 56/5.881 pacientes (0,9%), principalmente do subtipo morfeia linear. O EE foi observado em 23/56 (41%) dos pacientes com ELJ. Oito (35%) dos 23 pacientes com ELJ com EE eram sintomáticos e apresentavam azia (5/8), disfagia para sólidos e líquidos (3/8), náuseas e epigastralgias (1/8). A frequência de quaisquer manifestações extracutâneas cumulativas (calcinose, artrite/artralgia, envolvimento do sistema nervoso central, pneumonite intersticial, nefrite mesangial e/ou arritmias) foi significativamente maior em pacientes com ELJ com EE em comparação com aqueles sem essa complicação (56% vs. 24%, p = 0,024). Não foi evidenciada diferença nos dados demográficos, subtipos de ELJ e quaisquer manifestações extracutâneas entre os grupos (p > 0,05). A frequência de uso de metotrexato foi significativamente maior em pacientes com ELJ com EE em comparação com aqueles sem EE (52% vs. 12%, p = 0,002). O perfil de autoanticorpos (anticorpos antinucleares, anti-SCL-70, fator reumatoide, anticentrômero, anticardiolipina, anti-Ro/SSA e anti-La/SSB) foi semelhante nos dois grupos (p > 0,05). Conclusões: Este estudo demonstrou que o EE foi frequentemente observado em pacientes com ELJ, principalmente naqueles assintomáticos com o subtipo linear da doença. O EE ocorreu em pacientes com ELJ com outras manifestações extracutâneas e exigiu tratamento com metotrexato.

Morfea o esclerodermia localizada juvenil: caso clínico / Morphea or juvenile localised scleroderma: Case report

Introducción: La morfea o esclerodermia localizada juvenil (ELJ) es una enfermedad autoinmune, inflamatoria, crónica, lenta y progresiva del tejido conectivo, de causa desconocida, que afecta preferentemente la piel y los tejidos subyacentes. Objetivos: Comunicar un caso de esclerodermia localizada juvenil en una escolar, y contribuir a un diagnóstico y tratamiento oportuno de esta patología. Caso clínico: Niña de 8 años con placas induradas hipopigmentadas, de distribución lineal en la extremidad superior derecha de 2 años de evolución y placas induradas hiperpigmentadas de textura acartonada, con áreas de piel adelgazada, blanquecina y edema en la pierna y el tobillo. Los elementos clínicos y los exámenes de apoyo diagnóstico, incluyendo la histología, fueron compatibles con ELJ lineal, panesclerótica. Se inició tratamiento inmunosupresor y simultáneamente realizó fisioterapia y terapia ocupacional intensivas. Conclusiones: Presentamos un caso de ELJ de tipo lineal y panesclerótico, en el que hubo retraso de 2 años en el diagnóstico, no obstante la respuesta al tratamiento inmunosupresor fue favorable según lo esperado.

Introduction: Morphea or juvenile localised scleroderma (JLS) is an autoimmune, inflammatory, chronic, slowly progressive connective tissue disease of unknown cause that preferably affects skin and underlying tissues. Objective: To report a case of Juvenil Localised scleroderma in an 8-year old girl, contributing to an early diagnosis and treatment. Clinical case: The case is presented of an 8 year-old girl who presented with indurated hypopigmented plaques, of linear distribution in the right upper extremity of two years onset, together with papery texture hyperpigmented indurated plaques with whitish areas of thinned skin in right lower extremity, and leg and ankle swelling. The clinical features and diagnostic tests, including histology were compatible with linear and pansclerotic JLS. She started with immunosuppressive therapy, physiotherapy, and occupational therapy. Conclusions: We report a case of linear and pansclerotic ELJ type, in which there was a 2 year delay in diagnosis, however the response to treatment was positive as expected.
