Abstract:
Objective To analyze the change in immune function and therapeutic effectiveness of children with im-mune thrombocytopenic purpura and Helicobacter pylori(H. pylori)infection. Methods Eighty hospitalized chil-dren with thrombocytopenic purpura between March 2011 and March 2012 were as observation group,and then sub-divided into infected group and non-infected group according to whether they were infected with H. pylori;80 healthy children were as control group . Lymphocyte subsets ,clinical therapeutic effectiveness and recurrence rate among three groups were compared. Results The positive rate of H. pylori in observation group was significantly higher than control group(55.00% [44/80]vs 2.50% [2/80];χ2= 12.48,P= 0.008). There was significant differences in CD4+,CD4+/CD8+ ,and CD19+T lymphocyte among three groups (all P<0.05);CD4+ and CD4+/CD8+ T lymphocyte in infected group was significantly lower than non-infected group respectively ([13.40±4.65]% )vs [28.56± 3.82]% ;[0.69±0.18]% vs [1.04±0.23]% ),and CD19+T lymphocyte in infected group was significantly higher than non-infected group ([45.21±10.20]% vs [22.05±2.23]% );CD4+ and CD4+/CD8+T lymphocyte in non-in-fected group and infected group was significantly lower than control group ([40.20±3.42]% ,[1.54±0.42]% respec-tively),and CD19+T lymphocyte was significantly higher than control group ([11.02±2.89]% ). The overall therapeu-tic effectiveness in infected group and non-infected group was 90.91% and 91.67% respectively(P>0.05). The recur-rence rate of thrombocytopenic purpura after anti-H.pylori infection therapy in infected group was significantly lower than non-infected group (20.45% vs 30.56% ;χ2= 6.396,P= 0.038). Conclusion Detection of immune function is helpful for clinical diagnosis of H. pylori infection associated with immune thrombocytopenic purpura .
