Clinical study on the anti-helicobacter pylori treatment on immune thrombocytopenia in children / 重庆医学

Objective To explore the clinic character of immune thrombocytopenia (ITP) children infected with helicobacter py‐lori (Hp) and the effects of anti‐helicobacter pylori treatment on those children .Methods One hundred and forty‐two ITP children and 92 healthy children were conducted the 13C‐Urea breath test to determine the infections of Hp .The ITP children infected with Hp were divided into two groups :single drug group (48 cases ,treated only with corticosteroid ) and combined drugs group (49 ca‐ses ,treated with corticosteroid and anti‐helicobacter pylori treatment) .The platelet parameters ,platelet associated immunoglobulin and some lymphocyte subsets were analyzed .Results Ninety seven children infected with Hp were found in 142 ITP children (69 . 7% ) .In the mean time ,37 children infected with Hp were observed in 92 healthy children (40 .2% ) .After treatment of 6 months , the PLT ,PCT ,CD3+ ,CD3+CD4+ and CD3+ CD4+ /CD3+ CD8+ of ITP children in both group were increased ,and the increased degree of those parameters were much higher in combined drug group than those in single drug group (P< 0 .01) .However ,the MPV ,PDW ,PAIgG ,PAIgA and CD3+ CD8+ were more decreased than that of the single drug group(P<0 .01) .Conclusion The ITP children have a higher infection rate of Hp ,which may be involved in the pathogenesis of ITP .Anti‐helicobacter pylori therapy would improve the therapy efficacy of ITP children infected with Hp by improving their immunity .

Analysis of platelet-associated immunoglobulin subsets in idiopathic thrombocytopenia purpuras resistant to immuno therapy / 中国实用内科杂志

Objective To analyse platelete associated immunoglobulin(PAIg)subsets in idiopathic thrombocytopenia purpuras resistant to prednisone and cyclosporine.Methods Evaluate PAIg subsets in seventeen ITP patients resistant to prednisone,four cases resistant to both prednisone and cyclosporine,thirty in-patients responding to prednisone as the control.All patients were admitted from 1999 to 2004.Results The levels of PAIgA,PAIgG and PAIgM were significantly higher in the seventeen ITP patients resistant to prednisone than that in the thirty cases responsive to prednisone(P
