Retrospective view of primary Raynaud's phenomenon in childhood / Retrospectiva del fenómeno de Raynaud primario en la infancia

OBJECTIVES: Primary Raynaud's phenomenon (PRP) manifests as episodes of transient spasms of peripheral blood vessels. To elucidate the clinical clues and laboratory characteristics will facilitate the identification of PRP. METHODS: A retrospective data collection of clinical and laboratory characteristics of 58 children with PRP was performed between January 2007 and December 2016. RESULTS: A positive ANA test at lower titers <1:100 was detected in 24.1% of the patients. There was a significant relationship between presence of ANA positivity and migraine in female patients with PRP (p = 0.01; p = 0.020 respectively). The most common accompanying disorder was migraine which was detected in 37.9% of all patients with PRP. Hemoglobin and serum ferritin levels were significantly lower in PRP patients with migraine (p = 0.045; p < 0.05, respectively). Additionally, the mean platelet volume (MPV) measurements were significantly higher in patients with migraine compared to those without migraine (p = 0.045; p < 0.05 respectively). DISCUSSION: There is limited data concerning childhood PRP. For the first time we showed a high frequency of migraine in childhood PRP. Anemia and high MPV could be the underlying triggering factors of these two episodic diseases

OBJETIVO: El fenómeno de Raynaud primario (PRP, por sus siglas en inglés) se manifiesta como episodios de vasoespasmos transitorios de vasos sanguíneos periféricos. Elucidar las características clínicas y de laboratorio facilitará la identificación del PRP, así como las enfermedades acompañantes. MÉTODOS: Se realizó una un estudio retrospectivo de datos clínicos, de laboratorio y de tratamiento en 58 niños con PRP entre enero de 2007 y diciembre de 2016. RESULTADOS: Se detectó una prueba de ANA positiva en títulos inferiores (<1:100) en el 24,1% de nuestros pacientes. Se encontró correlación estadística entre la positividad de anticuerpos antinucleares y la presencia de migraña en las mujeres con PRP (p = 0,01; p = 0,020, respectivamente, prueba exacta de Fisher, prueba de corrección de continuidad de Yates). El trastorno más común fue la presencia de migraña en el 37,9% (n=22) asociado con PRP. Los niveles de hemoglobina fueron significativamente más bajos asociados con un bajo nivel de ferritina sérica en los casos de PRP con migraña (p = 0,045; p < 0,05). Además, las mediciones del volumen plaquetario medio (VPM) fueron significativamente mayores en los casos con migraña en comparación con aquellos sin migraña (p = 0,045; p < 0,05). DISCUSIÓN: Existen datos muy limitados sobre el PRP infantil. Hemos presentado por primera vez la asociación de PRP infantil y migraña en un estudio retrospectivo. La anemia y el VPM alto podrían formar parte de los factores predisponentes de ambas enfermedades episódicas
