ABSTRACT
Abstract Given the lack of standardized guidance for follow-up of patients with neuronal ceroid lipofucsinosis-2 disease in Latin-American countries and the heterogeneity of the region, an expert panel was created with the participation of 11 pediatric neurologists from Colombia, Argentina, Brazil and Chile. The aim of the expert panel was to describe a framework for standardized follow-up in patients with neuronal ceroid lipofucsinosis-2 disease, on or off therapy, that could benefit patients and treating physicians alike. Experts made recommendations in the following areas: seizures, abnormal movements and ataxia, sleep disorders and pain, cognitive function, visual function, hearing and speech, cardiac function, quality of life, and motor function. Recommendations include the most appropriate tools for use in the Latin-American context and health care systems, and provide feasible follow-up guidance, applicable in public and private healthcare facilities. They take into consideration the availability of clinical assessment resources, tools (scales, questionnaires, paraclinical tests) and access to these tools in Latin-American countries, as well as other regional and local needs defined by the participating experts.
ABSTRACT
La enfermedad de Pompe, o deficiencia de maltasa ácida o glucogenosis tipo II, es una grave enfermedad genética, autosómica recesiva, progresiva, poco frecuente, causada por la deficiencia en la enzima alfa glucosidasa. En la edad pediátrica, puede presentarse con la "forma clásica", la más conocida, con grave compromiso cardíaco y franca hipotonía, o con la "forma no clásica", con comienzo temprano del compromiso motor. La "forma de comienzo tardío" del adulto también puede ocurrir en la infancia o en la adolescencia. Se actualizan los hallazgos clínicos y de diagnóstico disponibles, ya que un tratamiento temprano con reemplazo de la enzima faltante puede mejorar la supervivencia y la calidad de vida del paciente. Se revisan los beneficios y los efectos adversos del tratamiento disponible y nuevas líneas de investigación terapéutica.
Pompe disease, also known as acid maltase deficiency or glycogenosis type II, is a rare severe, autosomal, recessive, and progressive genetic disorder caused by deficiency in alpha-glucosidase. The classic infantile-onset is the most broadly known form of Pompe disease, which presents with severe heart involvement and clear hypotonia, while the non-classic presentation occurs with early motor involvement. Late-onset Pompe disease develops in adults, but it may also occur during childhood or adolescence. Here we update the available clinical and diagnostic findings because an early management with enzyme replacement therapy may improve patients' survival and quality of life. We also review the benefits and adverse effects of available treatments and new lines of therapeutic research.
