ABSTRACT

The lysosomal storage diseases (LSD) are a group of approximately 50 hereditary diseases affecting the activity of several enzymes that degrade macromolecules within lysosomes. As consequence, incompletely degraded substrates are accumulated, causing cell damage and progressive multisystem diseases. Although they are considered part of the so called “rare diseases”, the LSD have become relevant since the availability for several of them of a specific treatment, through the periodic infusion of recombinant forms of the deficient enzymes. This enzyme replacement therapy can significantly improve the prognosis and the quality of life of patients. Several of the LSD affect the osteoarticular system, given symptoms that lead patients to consult first to the rheumatologist. The aim of this review is to highlight the clinical aspects of LSD, giving raise to the differential diagnosis with the rheumatic diseases...


Las enfermedades de depósito lisosomal (EDL) son un grupo de aproximadamente 50 patologías hereditarias que afectan la actividad de las enzimas que degradan diversas macromoléculas dentro de los lisosomas. Como consecuencia, se acumulan sustratos incompletamente degradados, produciendo daño celular y un cuadro clínico multisistémico y progresivo. Aunque se les considera parte de las llamadas “enfermedades raras”, las EDL han adquirido relevancia, pues desde hace pocos años es posible el tratamiento específico de varias de ellas a través de la infusión periódica de formas recombinantes de las enzimas deficientes, lo que puede mejorar significativamente el pronóstico vital y la calidad de vida de los pacientes. Dado que varias de las EDL comprometen al sistema osteoarticular, no es infrecuente que los pacientes consulten en primera instancia al reumatólogo. El objetivo de esta revisión es destacar los aspectos clínicos de aquellas EDL en las que se puede plantear el diagnóstico diferencial con patologías reumatológicas...

ABSTRACT

Las enfermedades de depósito lisosomal corresponden a alteraciones congénitas del metabolismo, las cuales se heredan de forma autosómica recesiva y están caracterizadas por el déficit específico de una hidrolasa lisosomal y por el acúmulo de su sustrato en varios tejidos del organismo. Dependiendo de la naturaleza bioquímica del sustrato acumulado, éstas pueden dividirse en esfingolipidosis, oligosacaridosis, mucolipidosis, mucopolisacaridosis y otras.


Lysosomal storage diseases are autosomal recessive disorders of inborn errors of metabolism, characterized by a deficiency in a specific lysosomal hydrolase and by accumulation of its specific substrate in various body tissues. Depending on the basis of the biochemical nature of the accumulated substrate, they can be divided in sphingolipidoses, oligosaccharidoses, mucolipidoses, mucopolysaccharidoses, and others.

ABSTRACT

Introducción. La enfermedad de células-I o mucolipidosis II, es una enfermedad rara autosómica recesiva que se clasifica dentro de las enfermedades lisosomales. Se le ha calificado como la forma más dramática de enfermedad por almacenamiento debido a la ausencia casi total de enzimas lisosomales en los fibroblastos lo que causa acumulación de sustratos no digeridos en los lisosomas. Caso clínico. Niña de 9 años con enfermedad de células I. Los rasgos sobresalientes fueron: facies tosca, proptosis ocular, narinas antevertidad, labios gruesos, macroglosia, hipertrofia gingival, cuello corto, tórax corto y ensanchado, xifoescoliosis toracolumbar, extremidades cortas deformadas por espasticidad y anquilosis de las articulaciones, abdomen prominente con hernia umbilical y hepatomegalia. Conclusiones. Se hace especial énfasis en el fenotipo y las manifestaciones clínicas y radiológicas que permiten diagnósticar esta enfermedad

ABSTRACT

Lysosomal storage disorders are a heterogeneous group of biochemical genetic disorders; currently 40-50 are known. The clinical phenotype is determined by the tissue distribution of the storage material and degree of enzyme deficiency. The genetic transmission is mostly autosomal recessive. Lysosomal storage disorders can be divided into three groups according to the major organ system pathology: (1) Primary involvement of the central nervous system without significant somatic or skeletal pathology. Disorders of grey matter, eg gangliosidosis and disorders of white matter eg the leucodystrophy are the most common; (2) Primary involvement of the reticuloendothelial system with or without associated neuropathology, eg Niemann-Pick disease and Gaucher disease; (3) Multisystem involvement in which skeletal manifestations are prominent features. The mucopolysaccharidosis and mucolipidoses are the two major forms with this clinical phenotype. Lysosomal storage disorders identified at Siriraj Hospital are neuronal ceroid lipofuscinosis, GMI gangliosidosis, mucolipidosis II, Maroteaux-Lamy, sialidosis, Sly syndrome, Hunter syndrome, Morquio syndrome, Gaucher disease, Niemann-Pick, Sandhoff disease, Pompe's disease and many more. Most patients came from the provinces where consanguinity is common. Confirmation usually is done by enzyme assays using skin fibroblast culture or leucocytes. Genetic counseling is extremely important and prenatal diagnosis is recommended to high-risk couple.
