The changes of CD cells in splenic tissue in patients with portal hypertension / 中国医师杂志

ABSTRACT

Objective To investigate the changes of CD cells in splenic tissue in patients with portal hypertension(PHT) accompanied by hypersplenism to explore the features of immunological function in patients with PHT.Methods The resected splenic tissue was made into paraffin sections for the detection of number and distribution of CD_3~+,CD_8~+,CD_(20)~+ and CD_(68)~+ cells,with the control of those in healthy individuals.Results The numbers of CD_3~+,CD_8~+,CD_(20)~+ and CD_(68)~+ cells remarkably decreased in patients with PHT accompanied by hypersplenism compared with those in normal controls.In normal controls,the CD_(68)~+ cells mainly existed in splenic lymphocyte nodules and red pulp(RP),and in patients with PHT,they existed in splenic lymphocyte nodules and periarterial lymphatic sheath(PALS).Compared with the normal controls,the numbers of CD_(68)~+ in splenic lymphocyte nodules,red pulp and marginal zone(MZ) decreased in patients with PHT.Conclusion The number and distribution of CD cells are changed in patients with PHT accompanied by hypersplenism.With splenectomy,the immunological function may be improved and the abnormalities in routine blood parameters and liver function be corrected.However,the immunological indexes detected in the study can not completely show the systematic immunological function of the patients with PHT accompanied by hypersplenism.Thus we should conduct a long-term follow-up study on immunological function in these patients.
