To observe an abnormal expression of humoral immune response induced by memory B cells in tonsils and peripheral blood of patients with IgA nephropathy (IgAN), the variation of memory B cells after tonsillectomy, and to discover the role of tonsillectomy in IgAN.In the study, 28 patients were diagnosed as IgAN via renal biopsy, and 27 patients suffering from chronic tonsillitis without nephritis and 10 normal human beings were selected as controls. The expression of memory B cells in the tonsils and peripheral blood was tested by flow cytometry, and the same method was used to test the variation of the expression of memory B cells in peripheral blood of patients with IgAN after tonsillectomy.In this study, higher percentages of memory B cells were observed in tonsil and peripheral blood of IgAN patients, which were 5.72%±5.26%, 4.92%±5.10%. After tonsillectomy, the percentage of memory B cells was 1.10%±0.65%, lower than that before tonsillectomy (P0.05). Meanwhile, in tonsils and peripheral blood, the percentage of memory B cells varied with the variation of the urinary findings of the IgAN patients.The percentage of memory B cell in tonsils and peripheral blood could predict disease progression of IgAN to a certain extent. |
