Hyperimmunoglobulinemia and IgG Subclass Abnormalities in Children With Gaucher Disease

Gaucher disease (GD) is the most common lysosomal storage disorder, the aim of the current study was to investigate hyperimmunoglobulinemia and abnormalities of serum immunoglobulin G (IgG) subclasses in children with GD and the relation of those findings to the GD phenotype and genotype, duration of enzyme replacement therapy (ERT), and infection frequency. The study included 20 Egyptian children with GD receiving ERT and 20 age-matched and sex-matched healthy children as controls. Serum Ig and serum IgG subclass levels were measured in the children with GD. Serum IgG subclass levels were measured in the control subjects. Hyperimmunoglobulinemia was present in 15 of the 20 (75%) children with GD. In addition, it is found significantly lower IgG2 levels and significantly higher IgG3 levels in the GD group than in the control group (P
