ABSTRACT
ObjectiveTo investigate clinical effect of eradication of helicobacter pylori in patients with idiopathic thrombocytopenic purpura(ITP). Methods145 cases with HP-positive ITP paitients were divided into two groups( platelet counts results ＜ 50 × 109/L and platelet counts results ＞ 50 × 109/L). 95 cases with platelet counts ＜50 × 109/L were divided into two groups and treated with prednisone and Hp eradication(48 cases) or with prednisone without Hp eradication(47 cases). 95 cases with platelet counts ＞ 50 × 109/L were divided into two groups and treated with Hp eradication 25 cases)or follow-up without any treatment(25 cases). ResultsThe total effective rate in group treated with prednisone and Hp eradication was significantly higher than that in group with prednisone without Hp eradication( 92％ vd 75％, x2 ＝ 5.01 ,P ＜ 0.05 ). The recurrence rate in two year in group treated with prednisone and Hp eradication was significantly lower than that in group with prednisone without Hp eradication( 19％ vs 49％,x2 ＝ 9. 69, P ＜ 0. 01 ). HP eradicatiaon single can improve platelet counts in HP-positive ITP paitients.ConclusionThe detection and eradication of H pylori infection should be considered in patients with ITP. H. pylori eradication could be used for initial treatment in HP-positive ITP paitients.
ABSTRACT
Objective To study the effect of serum leptin in “two hits” of nonalcoholic fatty liver disease (NAFLD).Methods Fasting serum leptin(LEP) ,malondialdehyde(MDA) ,hyaluronic- acid(HA) ,type Ⅲ procollagen ( PCⅢ), laminin ( LN), and type Ⅳ collagen ( Ⅳ-C ) were detected in 43 simple nonalcoholic fatty liver( NAFL ) patients ,41 NASH patients and 40 healthy subjects. Insulin resistance was estimated by HOMA value and its relatio nship with leptin level in NAFLD was analyzed. The severity of lipid peroxidation was estimated by MDA and its relationship with leptin level in NAFLD was analyzed. The relationship of serum fibrosis markers with leptin level in NAFLD also was analyzed. Results Serum leptin, HOMA value in NAFLD were higher than those of healthy controis. MDA,PC Ⅲ 、Ⅳ-C 、LN 、HA in NASH were higher than those of healthy controls or simple NAFL patients. ,HOMA value, in NAFLD positively correlated with leptin. MDA, PC Ⅲ、 Ⅳ-C 、LN、HA in NASH positively correlated with leptin. Conclusion Serum leptin closely correlated with insulin resistance which results in “First hit” of NAFLD. There was certain relationship of leptin with “Second hit” of NAFLD. Leptin should be one of the factors which result in liver fibrosis.
