RESUMO
OBJECTIVE: The aim of this study was to analyze the correlation of vitamin D levels with clinical parameters, bone mineral density (BMD), quality of life (QoL) and nailfold capillaroscopy (NC) in patients with diffuse systemic sclerosis (SSc). METHODS: Thirty-eight female patients with diffuse SSc were analyzed regarding 25-hydroxyvitamin D (25OHD) serum levels. At inclusion, organ involvement, autoantibodies, modified Rodnan skin score (mRSS), Medsger Disease Severity Index (MDSI), body mass index (BMI), BMD, NC, Short-Form-36 Questionnaire (SF-36), and Health Assessment Questionnaire (HAQ), were performed through a standardized interview, physical examination and electronic chart review. RESULTS: Mean 25OHD serum level was 20.66±8.20ng/mL. Eleven percent of the patients had 25OHD levels ≤10ng/mL, 50% ≤20ng/mL and 87% ≤30ng/mL. Vitamin D serum levels were positively correlated with BMI (r=0.338, p=0.038), BMD-total femur (r=0.340, p=0.037), BMD-femoral neck (r=0.384, p=0.017), SF-36-Vitality (r=0.385, p=0.017), SF-36-Social Function (r=0.320, p=0.050), SF-36-Emotional Role (r=0.321, p=0.049) and SF-36-Mental Health (r=0.531, p=0.0006) and were negatively correlated with HAQ-Reach (r=-0.328, p=0.044) and HAQ-Grip Strength (r=-0.331, p=0.042). A negative correlation with NC-diffuse devascularization (p=0.029) and NC-avascular area (p=0.033) was also observed. CONCLUSION: The present study provides novel evidence demonstrating that low levels of 25OHD have a negative impact in diffuse SSc QoL and further studies are needed to define whether vitamin D supplementation can improve health related QoL in these patients. The additional observation of a correlation with severe NC alterations suggests a possible role of 25OHD in the underlying SSc vascular involvement.

RESUMO Objetivo: O objetivo deste estudo foi analisar a correlação entre os níveis de vitamina D e parâmetros clínicos, densidade mineral óssea (DMO), qualidade de vida (QV) e capilaroscopia periungueal (CPU) em pacientes com esclerose sistêmica difusa (ES). Métodos: Mensuraram-se os níveis séricos de 25-hidroxivitamina D (25OHD) de 38 pacientes do sexo feminino com ES difusa. No momento da inclusão, analisaram-se o envolvimento de órgãos, autoanticorpos, escore cutâneo de Rodnan modificado (ERM), Medsger Disease Severity Index (MDSI), índice de massa corporal (IMC), DMO, CPU, Short-Form-36 Questionnaire (SF-36) e Health Assessment Questionnaire (HAQ) por meio de uma entrevista padronizada, exame físico e avaliação de prontuário eletrônico. Resultados: A média do nível sérico de 25OHD foi de 20,66 ± 8,20 ng/mL. Dos pacientes, 11% tinham níveis de 25OHD ≤ 10 ng/mL, 50% ≤ 20 ng/mL e 87% ≤ 30 ng/mL. Os níveis séricos de vitamina D estiveram positivamente correlacionados com o IMC (r = 0,338, p = 0,038), DMO-fêmur total (r = 0,340, p = 0,037), DMO-colo femoral (r = 0,384, p = 0,017), SF-36-Vitalidade (r = 0,385, p = 0,017), SF-36-Aspecto social (r = 0,320, p = 0,050), SF-36-Aspecto emocional (r = 0,321, p = 0,049) e SF-36-Saúde mental (r = 0,531, p = 0,0006) e se correlacionaram negativamente com o HAQ-Alcance (r = –0,328, p = 0,044) e HAQ-força de preensão (r = –0,331, p = 0,042). Também foi observada uma correlação negativa com a CPU- desvascularização difusa (p = 0,029) e CPU-área avascular (p = 0,033). Conclusão: O presente estudo fornece evidências novas de que níveis baixos de 25OHD têm um impacto negativo sobre a qualidade de vida de pacientes com ES difusa e que são necessários mais estudos para definir se a suplementação de vitamina D pode melhorar a qualidade de vida relacionada com a saúde desses pacientes. A observação adicional de uma correlação com alterações graves na CPU sugere um possível papel da 25OHD no envolvimento vascular subjacente da ES.

Paciente femenina de 30 años de edad que consulta por un cuadro de hiperhidrosis, asociado a sensación de calor desde su niñez. Sufre crisis de calor en cara, cuello, parte superior del tronco y los cuatro miembros, que la inducen a transpirar. Durante estos episodios nota sensación de calor, dolor y con aparición de rubor en manos y pies. Los síntomas ceden con aplicación de frío. Estos síntomas que presenta desde su adolescencia, dificultan el sueño, sus tareas habituales y el trato social. Sus antecedentes familiares respecto del mismo cuadro son floridos. Los estudios hematológicos, inmunológicos, la electromiografía y el ecodoppler de miembros superiores, resultaron dentro de límites normales. En el video sobre capilaroscopía periungueal de manos, se constata cambios micro vasculares inespecíficos. En la prueba de provocación mediante aumento de la temperatura, se obtiene resultado positivo a 39°C para miembros superiores. La paciente presenta signo-sintomatología compatible con hiperhidrosis focal primaria. Los episodios de calor, rubor y dolor de los cuatro miembros, que ceden a la exposición al frío fueron interpretados como eritromelalgia, en base a la clínica y los antecedentes familiares. Para la hiperhidrosis se indica solución de cloruro de aluminio hexa-hidratado al 20%, de aplicación tópica y para la eritromelalgia citrato de magnesio en grageas 528 mg, de dos a cuatro por día. Según la bibliografía por nosotros revisada, la asociación de hiperhidrosis focal primaria y eritromelalgia primaria familiar, no se ha registrado en la literatura.(AU)
Female patient, aged 30 years-old, attending a medical consultation with hyperhidrosis associated with episodes of warmth and sweating since childhood, located in face, neck, upper thorax and extremities. These episodes are accompanied by heat, pain and reddening in hands and feet. The symptoms disappear to cold exposure. These symptoms altered sleep, daily activities and social life. A positive family history with similar clinical characteristics was obtained. Hematological and immunological studies, as well as upper limbs electromyography and ecodoppler are within normal parameters. Unspecific microvascular alterations were observed with finger-periungueal video capillaroscopy. A provoking test yielded positive results when rising temperature to 39°C in upper limbs. The patient symptoms are compatible with focal primary hyperhidrosis. Heat, reddening and pain in the upper and low extremities responding to cold exposure and the positive family history led us to diagnose erythromelalgia. The hyperhidrosis treatment consisted of a topical application of 20% hexhydrate aluminum chloride. For erythromelalgia treatment 528 mg magnesium citrate pills, 2-4 daily were administered. Literature review to find out association of primary focal hyperhidrosis with primary familiar erythromelalgia was negative.(AU)
