Massive splenomegaly in Northern Zambia. II. Schistosomal splenomegaly and elevated IgG.
Twenty-three patients from Northern Zambia with massive splenomegaly due to chronic schistosomiasis were studied. The mean serum IgG levels were found to be extremely high compared with local blood donors and local patients with Tropical Splenomegaly Syndrome (TSS). Mean serum IgG levels also appear to be higher in Zambians with schistosomal splenomegaly than in those reported in patients from most other areas. Mean IgM levels of patients with schistosomal splenomegaly were higher than those of local blood donors, but not as high as in the TSS. IgG and IgM estimations are sometimes of value in the differential diagnosis of splenomegaly in the tropics.
