CANDLE syndrome: chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature-a rare case with a novel mutation.

UNLABELLED: We described herein a patient with chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome and a novel mutation in PSMB8 gene. This patient had multiple visceral inflammatory involvements, including rare manifestations, such as Sweet syndrome and pericarditis. A 3-year-old male, Caucasian, was born to consanguineous healthy parents. At the age of 11 months, he presented daily fever (temperature >40 °C), irritability, hepatomegaly, splenomegaly; and tender and itching, erythematous papular and edematous plaque lesions. Echocardiogram showed mild pericarditis. Skin biopsy revealed a neutrophil infiltrate without vasculitis suggesting Sweet syndrome. Mutational screening of PSMB8 gene revealed homozygous c.280G>C, p.A94P mutation. He responded partially to high doses of oral glucorticoid and intravenous methylprednisolone. Colchicine, azathioprine, methotrexate, cyclosporine, and intravenous immunoglobulin were not efficacious. At the age of 3 years and 1 month, tocilizumab was administered resulting in remission of daily fever and irritability. However, there was no improvement of the skin tenderness and itching lesions. CONCLUSION: A new mutation in a CANDLE syndrome patient was reported with pericarditis and mimicking Sweet syndrome. The disease manifestations were refractory to immunosuppressive agents and partially responsive to tocilizumab therapy. WHAT IS KNOWN: • Proteasome-associated autoinflammatory syndromes (PRAAS) include four rare diseases. • Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome was seldom reported. What is New: • We described a Brazilian patient with CANDLE syndrome possessing a novel mutation in the PSMB8 gene. • This patient had multiple visceral inflammatory involvements, including rare manifestations, such as pericarditis and mimicking Sweet syndrome.

Esophageal abnormalities in juvenile localized scleroderma: is it associated with other extracutaneous manifestations?

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.
