Pryor [ 49 ]. The syndrome is characterized by macroglobulinaemia with overproduction of immunoglobulin, especially of the IgM class, which aggregate into high molecular immune complexes and cause persistent splenomegaly because of prolonged clearance from the reticuloendothelial tissue [ 3 ]. Chronic malaria was demonstrated in those successfully treated but not in those who failed to respond to therapy.

Tropical splenomegaly syndrome – Wikipedia

Genetic factors are likely to be involved in the development of HMS. HMS is caused by a chronic antigenic stimulation derived from the malaria parasite. In other papers, the exclusion of other causes of splenomegaly hyperreactie an endemic area was sufficient to consider a patient as affected by HMS [ 5657 ].

Rev Soc Bras Med Trop. Palpable below umbilicus but not below a horizontal line halfway between umbilicus and pubic symphysis. Reduction of spleen size in a child maalrial hyperreactive malarious splenomegaly HMS treated outside the Brazilian endemic area of malaria with only one course of quinine.

This occurrence was attributed to persistence of the underlying stimulus to reticulo-endothelial system [ 95 ].

Sickle cell disease and hyperreactive malarial splenomegaly HMS in young immigrants from Africa. He was born in Sierra Leone and had migrated to the United Kingdom 8 years before. An initial amplification of the outer regions of the two genes was followed by a nested PCR with allelic family specific primer hyperreeactive [ 13 ]. Open in a separate window.

However, other authors observed that the syndrome tended to quickly relapse once anti-malarial therapy was stopped [ 7578 ]. SL contributed to the study design, performed the systematic review, wrote the first version of the manuscript.

Is this more frequent than it appears? This study was carried out in Khartoum, Sudan. This finding raised the possibility of chronic malaria, hemozoin is splenlmegaly occasionally seen in chronic schistosomiasis. Received Dec 29; Accepted Apr Use of immunoglobulin gene rearrangements to show clonal lymphoproliferation in hyper-reactive malarial splenomegaly.

Diagn Microbiol Infect Dis. The treatment of makarial splenomegaly syndrome involve administration of antimalarial drug followed by prophylaxis for prolonged periods of time. Polymerase Chain Reaction PCR PCR analysis was carried out on samples collected from all patients for detection of malaria parasites; the primers specific for the polymorphic regions block 2 of merozoite surface protein 1 MSP1 and block 3 of MSP2 were designed and described previously.

Clinical trial of malaria prophylaxis in tropical splenomegaly syndrome. Cause of splenomegaly uncertain. Spleen palpable, but not beyond a horizontal line halfway between the costal margin and umbilicus, measured in a line dropped splenomegzly from the left nipple.
