目的　探讨大剂量激素对过敏性紫癜的疗效。方法　对 3 4例过敏性紫瘢患者 ,均给予大剂量激素序贯治疗 ,并随访观察 1～ 3年。结果　 3 4例均治愈 ,1例未遵嘱服用激素者短时复发后再次治愈 ,余 3 3例均无复发。结论　大剂量激素治疗过敏性紫癜疗效较好     

白细胞介素-18在特发性血小板减少性紫癜中作用的研究

目的 探讨白细胞介素-18(IL-18)与特发性血小板减少性紫癜(ITP)发病的关系,研究其在ITP发病中的作用及临床意义.方法 酶联免疫吸附测定(ELISA)测定血浆IL-18,对36例ITP患者和正常对照组血浆IL-18的水平进行分析.结果 ITP组血浆IL-18含量为(538.31±111.33)pg/ml,正常对照组血浆IL-18含量为(489.44±49.07)pg/ml.IL-18含量与血小板数量呈显著性负相关(r=-0.395,P＜0.05).结论 ITP发病时患者血浆中的IL-18水平比正常对照组明显升高,IL-18与ITP发病密切相关.     

Sequential occurrence of IgA nephropathy and Henoch-Schönlein purpura: support for common pathogenesis

We report a patient who developed Henoch-Schönlein purpura (HSP) 13 years after he presented with IgA nephropathy (IgAN). In both HSP and IgAN renal biopsy most commonly reveals focal proliferative glomerulonephritis on light microscopy and immunofluorescence displays mesangial IgA deposits. In addition, patients with HSP or IgAN have elevated serum IgA levels, circulating IgA immune complexes, IgA-bearing lymphocytes, immunoglobulin-producing cells, and binding of IgG to glomerular components of similar molecular weight. The occurrence of both diseases in the same patient or the same families and the presence of immune abnormalities compatible with HSP or IgAN in relatives of patients with these diseases suggest a common pathogenesis.

过敏性紫癜的心肌损害

目的观察儿童过敏性紫癜并心肌损害的发生率及临床特点。方法回顾性分析93例过敏性紫癜患儿并心肌损害的临床资料，对其发生率、临床表现及其他系统损害的关系和预后进行分析。结果497例过敏性紫癜患者中有93例（18．71％）有心肌受损，主要表现为心肌酶学异常和（或）心电图异常。所有病例应用肾上腺皮质激素治疗后均治愈。结论过敏性紫癜合并心肌损害是临床较常见的表现，早期识别并及时应用激素治疗及对症处理可避免严重并发症的发生，提高治疗效果。     

从热、虚、瘀辨证论治小儿过敏性紫癜

从热、虚、瘀三个方面论述了小儿过敏性紫癜的病因病机特点，抓住病因病机的核心，确定了热伤血络、阴虚火旺、气不摄血三个本证证型和风热、热毒、湿热、血瘀四个标证证型。采用本证和标证相结合的方法对小儿过敏性紫癜进行辨证论治，并从理论上探讨了该方法的科学性和实用性。     

免疫性血小板减少性紫癜辨证分型与血小板表面相关抗体及T淋巴细胞亚群的关系

为探讨免疫性血小板减少性紫癜（ITP）中医辨证分型与免疫机理的关系,将ITP患者中医辨证分型结合血小板相关抗体（PAIg）及T淋巴细胞亚群进行分析。发现作为本病主要抗体的PAIgG脾肾阴亏型明显高于脾虚失统型（P<0.01）;OKT₈⁺值亦显著高于脾虚失统型（P<0.05）,OKT₄⁺/OKT₈⁺比值则明显低于脾虚失统型（P<0.05）。提示脾肾阴亏型的免疫损伤程度较脾虚失统型严重。     

Subacute (acute,persistent) thrombotic microangiopathy

Six patients with prolonged acute courses of thrombotic microangiopathy are reviewed. These patients had in common courses of acute disease requiring plasma support for more than 3 months, with subsequent complete remission. Plasma support requirements may be prodigious, and the acute course may require more than 100 plasma exchanges before a stable remission is achieved. These patients appear to represent a subset of thrombotic microangiopathy distinct from the more common acute T.T.P. course, which resolves in 3–6 weeks, and the chronic relapsing pattern, which may have a short or prolonged acute course. © 1992 Wiley-Liss, Inc.
