RESUMO
OBJECTIVES: Restless legs syndrome (RLS) is a frequent complication of hemodialysis that has been associated with poor quality of life and increased risk for complications. Nevertheless, few studies regarding this entity exist in resource-limited settings. To determine the prevalence of RLS among Mexican patients on hemodialysis; and compare these patients with a control group of the same population. METHODS: We recruited 105 hemodialysis patients. Restless legs syndrome was diagnosed according to the updated criteria set out by the International RLS Study Group. We selected patients who did not meet the criteria, as controls. RESULTS: We found an RLS prevalence of 18%. The RLS patients had a significantly higher prevalence of iron deficiency anemia and uremic pruritus. None of the patients reported RLS symptoms prior to hemodialysis initiation. CONCLUSIONS: Restless legs syndrome is common among Mexican patients on hemodialysis. Larger studies are required to address the impact of RLS in hemodialysis patients.

RESUMEN El síndrome de piernas inquietas (SPI) es una complicación de la hemodiálisis que se ha asociado con menor calidad de vida y riesgo aumentado de complicaciones. Sin embargo, existen pocos estudios acerca de esta entidad en escenarios de recursos limitados. Objetivos: Determinar la prevalencia de SPI en pacientes mexicanos en hemodiálisis, y comparar las características con un grupo control de la misma población. Métodos: Reclutamos 105 pacientes en hemodiálisis. El SPI se diagnosticó de acuerdo con los criterios actualizados del grupo de estudio internacional del síndrome de piernas inquietas. Seleccionamos a los pacientes que no cumplieron dichos criterios como controles. Resultados: Encontramos una prevalencia de SPI del 18%. Los pacientes con SPI tenían una prevalencia más alta de anemia ferropénica, y prurito urémico. Ninguno de los pacientes reportó síntomas de SPI previo a iniciar la hemodiálisis. Conclusiones: El SPI es frecuente en pacientes mexicanos en hemodiálisis; se requieren estudios más grandes para evaluar el impacto del síndrome en ésta población.
