Effect of splenectomy on destructive bone changes in children with chronic (Type I) Gaucher disease.

The incidence and severity of osteolytic bone changes in patients with chronic (Type I) Gaucher disease splenectomized in the first decade of life were compared to those in patients of the same age group and similar degree of severity of the disease in whom the spleen remained intact at least until the second half of the second decade. The size of the spleen, measured by palpation, was used as an index of severity. In the splenectomized group osteolytic changes appeared within a few months following splenectomy in six out of eight cases. The changes were severe in five cases and moderate in one. In contrast, in the non-splenectomized group, evidence of bone destruction was found in two out of eight patients and classified as mild in both cases. Furthermore, in three patients in this group, who remained free of bone destruction until splenectomy in the second half of the second decade, osteolytic lesions appeared soon after the operation. Children with chronic Gaucher disease can be spared a great deal of suffering caused by bone disease, if splenectomy is avoided or postponed as far as possible.
