Аннотация
INTRODUCTION: Hematopoietic stem cell transplantation (HSCT) comprises one of the two main treatment regimens for patients with mucopolysaccharidoses (MPS). There is a scarcity of literature concerning the process of growth in children with Mucopolysaccharidosis type I (MPS I) and Mucopolysaccharidosis type I (MPS II) after HSCT. The aim of this manuscript was to evaluate the therapeutic effect of HSCT on the heights of patients with MPS I and MPS II.
MATERIAL AND METHODS: It was an observational, single-center study on patients with MPS I and II treated with HSCT.
RESULTS: 6 MPS patients, including 4 MPS I and 2 MPS II, underwent HSCT at a median age of 2 years. All patients are alive to date, with a median age of 7.7 years (range 5.5-12 years) at the last follow-up. In both (MPS I and MPS II) groups of patients treated with HSCT, the growth rate was higher than in untreated patients and was found to be in line with the population norm. In both MPS I and MPS II patients who were treated with HSCT, normalization of urinary GAG excretion was observed. Additionally, no bands of DS and HS in GAG electrophoresis were visible.
CONCLUSIONS: Both MPS I and MPS II patients presented height gain after HSCT compared to the curves of untreated patients. The absence of dermatan sulphate after HSCT could lead to normal growth in bone length.
