Abstract

Pompe is a rare disease caused by a deficiency of the lysosomal enzyme acid-α-glucosidase (GAA). This results in glycogen accumulation in tissues, especially muscles, and impairs their ability to function normally. The most severe is the classic infantile-onset disease, with death before 1 year of age. At Vietnam National Children’s  Hospital, enzyme replacement therapy to treat Pompe disease started since 2015. The study was performed to identify frequency and cause of hospitalization of 15 Pompe patients who are being treated with enzyme replacement therapy as a case series study. The result showed that 15 patients were from the North and North Central provinces. The rate of male/female was 7/8. The mean age of diagnosis was 4.6 ± 4 months, the current mean age was 3.1 ± 0.9 years. The median frequency of hospitalization in the first year was 2 times / year, in the 2nd  year was 1 time / year, in the 3rd  year was 2 times / year, in the 4th year was 0.5 times / year, in the 5th  year was 1 time / year. The median day of hospitalization in the first year was 17 days, the  2nd  year was 7 days, the 3rd  year was 22 days, the 4th year  was 1.5 days, the 5th year was 8 days.The reasons for hospitalization of patients are respiratory infections ( 91.4%), influenza infection, measles (4.3%), gastrointestinal disease (4.3%). The study showed that hospitalization frequency of Pompe patients tends to decrease with treatment time and the main cause of hospitalization was respiratory tract infection; it is recommended to expand neonatal screening and molecular analysis for early diagnosis and prenatal genetic counseling.
