La acrosteólisis como indicador de gravedad en los pacientes con esclerosis sistémica / Acro-osteolysis as an indicator of severity in systemic sclerosis

Introducción. La esclerosis sistémica es una patología rara que afecta predominantemente a las mujeres. Se utiliza la escala de Medsger para evaluar la severidad, pero precisa de estudios caros y de difícil acceso y no incluye complicaciones tales como acrosteólisis, calcinosis, enfermedades pericárdicas o hipotiroidismo, que se presentan con relativa frecuencia en esta enfermedad. No existen estudios que tengan en cuenta si las comorbilidades, como la cirrosis biliar primaria, se asocian a la gravedad. Objetivos. Establecer la correlación entre la gravedad y la presencia de complicaciones asociadas. Métodos. Se estudió a 40 pacientes con esclerosis sistémica, divididos entre terciles conforme a su gravedad. Se describen las variables dicotómicas con porcentajes, mientras que las variables dimensionales se describen con medias+DE. La interferencia estadística se llevó a cabo con la prueba de la χ2 y de Kruskal-Wallis con la prueba de Dunn después del test, según procediera. Se estableció la significación estadística en p<0,05. Resultados. De todas las complicaciones analizadas, solo había diferencias en el caso de la acrosteólisis. Entre las comorbilidades, la cirrosis biliar primaria no se asocia a la gravedad (AU)

Introduction. Systemic sclerosis is a rare disease that predominantly affects women. The Medsger severity scale has been used to assess the severity, but it requires expensive and poorly accessible studies and it does not include complications such acrosteolysis, calcinosis, pericardial disease or hypothyroidism that occur on a relatively frequent basis in this disease. There is no study that considers if comorbidities, such as primary biliary cirrhosis, are related to gravity. Objectives. To determine the correlation between severity and the presence of such complications. Methods. 40 patients with systemic sclerosis, dividing them into tertiles according to severity were studied. Dichotomous variables were described using percentages, while dimensional by averages+SD. Statistical inference was performed using chi square test or Kruskal-Wallis test with Dunn post-test, as appropriate. A significance at P<.05 was set. Results. Of all the complications studied there were only differences in severity with acrosteolysis. Within comorbidities, primary biliary cirrhosis is not associated with gravity (AU)
