Pompe's disease is an autosomal recessive disease caused by deficiency of acid-alpha-glucosidase.Authors analyzed the phenotype of 11 Hungarian patients with Pompe's disease and evaluated clinical parameters and response to enzyme replacement therapy during a long-term follow-up in 8 patients.One patient with atypical infantile form presented with cardiomyopathy and a very slow progression of motor deficits; after 2 years of enzyme replacement therapy no disability was present at the age 6 years. Another patient was asymptomatic at the age of 2.5 years. The adult onset form was characterized by slight to prominent limb-girdle myopathy with an age of onset between 20 and 50 years. In 3 of such cases respiratory insufficiency was also present.Hungarian patients with Pompe's disease presented with a wide phenotypic variability ranging from atypical early childhood form with slowly progressive course to late-onset limb-girdle myopathy with variable courses. Enzyme replacement therapy resulted in significant improvement in motor and respiratory functions in most of the patients.

A porc-haj hypoplasia ritka, autoszomális recesszív öröklődésmenetű primer immunhiány-betegség, amelyre a döntően T-sejtes immundeficiencia mellett metaphysealis chondrodysplasia jellemző. A közleményben a szerzők egy esetismertetés kapcsán mutatják be a betegség klinikumát és a jellemző laboratóriumi leleteket, összefoglalják a kórkép molekuláris patomechanizmusával kapcsolatos ismereteket és a kezelés lehetőségeit.
