Abstract:
Objective:To evaluate the short-term efficacy and the improvement of quality of life of enzyme replacement therapy (ERT) with Imiglucerase on children with Gaucher disease(GD) through the same time monitoring.Methods:Six children diagnosed as GD who were treated by ERT with Imiglucerase in the Department of Hematology of the Children′s Hospital of Shanxi Province from May 2019 to May 2020 were recruited.Every 3 months, the sizes of the liver and spleen was palpated, the change of bone pain was recorded, and the haematological index was examed.The volumes of the liver and spleen at 1-year treatment were measured by CT.Bone involvement was examined by magnetic resonance imaging (MRI). In addition, the body weight, height, and the 36-Item Short Form Survey (SF-36) were measured and compared with pre-treatment levels.These data were analyzed statistically by SPSS 25.0 and the difference between pretherapy and post-treatment was compared by paired t test. Results:Six children diagnosed as GD received ERT with Imiglucerase.No adverse events were reported.Decreased volumes of the liver and spleen, and increased hemoglobin level and platelet count were detected after 3-6 months of ERT.After 1 year of ERT, hemoglobin level significantly increased compared with pre-treatment level ( t=4.200, P=0.008). Although the platelet count increased at 1-year ERT, it was comparable with pre-treatment level ( t=2.260, P=0.073). The volumes of liver and spleen decreased by (22.10±15.28)% ( t=2.725, P=0.042) and (47.10±18.42)% ( t=3.162, P=0.034) after 1 year of ERT, respectively.During the first year of ERT, the height and weight increased (6.17±2.86) cm ( t=5.286, P=0.003) and (4.08±2.01) kg ( t=4.975, P=0.004), respectively.SF-36 score increased significantly from (489.35±103.99) points to (632.75±73.34) points ( t=5.740, P=0.002). After 1 year of ERT, 1 patient still had bone pain, and 2 cases were worse in bone MRI, which may be attributed to the short period of follow-up and insufficient dose, and another 3 had no change in bone MRI. Conclusions:ERT ameliorates GD-associated anemia, organomegaly and growth retardation, and improves the growth rate of body mass and height and the quality of life in the short period.However, short-term ERT does not improve the bone disease.
