    • 摘要: Objective:To study the positive distribution rate of Coombs test in patients with clinical anemia and blood transfusion,and its effect on clinical blood transfusion.Methods:Seventy patients with hemoglobin level in the normal range were enrolled into control group,while 130 patients with anemia or blood transfusion who's hemoglobin level was lower comfirmed by micro-column gel antihuman globin detection card and 70 surgical patients with anemia or blood transfusion who's hemoglobin level was lower comfirmed by micro-column gel anti-human globin card were enrolled into anemia or blood transfusion (A or BT) group.And coomb's test performed for all the patients,in which the positive patients in Department of Internal Medicine need to be re-typed.Results:Among 70 surgical patients with anemia or blood transfusion,14 cases were directly detected to be anti-human globine positive with detection rate 20%;among 130 internal medicine patients with anemia or blood transfusion,54 cases were directly detected to be anti-human globine positive with detection rate 41.4%.Among 270 cases,the highest positive rate (66.7%) was observed in patients with 50-59 g/L of hemoglobin.According to type test,the samples of 54 patients with anemia in Department of Internal Medicine,who were directly selected to be anti-human globin positive,could be divided into anti-C3d(7 cases,accounting for 13.0%),anti-IgG(12 cases accounting for,22.2%) and anti-C3d + anti-IgG (35 cases,accounting for 64.8%),while according to diseases,the anti-human globin positive ratio was high in tumor cancer,hephropathy and gastroenteropathy patients,and patients in intensive care unit,moreover the blood transfusion frequency of these patients was higher than that of patients with anti-human globin negative (P < 0.05).Conclusion:The important causes affecting the anemia in patients may relate with direct anti-human globulin positive test,therefore the interference of direct anti-human globin positive should be excluded in the course of blood transfusion,so as to ensure the effectiveness of blood transfusion.%目的:研究直接抗人球蛋白试验(Coombs试验)在临床贫血和输血患者中的阳性分布率.方法:随机选取本院2014-2016年70例经微柱凝胶抗人球蛋白检测卡检测血红蛋白含量在正常范围内者做为对照组,130例经微柱凝胶抗人球蛋白检测卡检测为血红蛋白含量较低的内科贫血患者或者输血患者、以及70例经微柱凝胶抗人球蛋白检测卡检测为血红蛋白含量较低的外科贫血患者或者输血患者为观察组,并对所有患者进行Coombs试验,其中对直接被检出阳性的内科患者需再行分型试验.结果:外科贫血患者或者输血患者中有14例被直接检出抗人球蛋白阳性,其抗人球蛋白直接检出率为20.0%;内科贫血患者或者输血患者中有54例被直接检出抗人球蛋白阳性,其抗人球蛋白直接检出率为41.4%.在270例中血红蛋白含量分布在50-59g/L的阳性率最高,占59.8%.54例被直接检出抗人球蛋白阳性的内科贫血患者的标本按分型试验可分为抗-C3d 7例,占13.0%;抗-IgG 12例,占22.2%;抗-C3d+抗-IgG 35例,占64.8%;54例被直接检出抗人球蛋白阳性的内科贫血患者按科室分布,其中以消化内科、肿瘤科、肾病科、胃肠病和ICU所占的比例最高,且这类患者的输血频率也较阴性患者高(P<0.05).结论:影响患者贫血的重要原因可能与直接抗人球蛋白试验阳性有关,因此在患者的输血治疗过程中应该注意到要排除直接抗人球蛋白试验阳性的干扰,以保证输血的有效进行.

Methods The clinical data of 29 children with autoimmune hemolytic anemia during January 2013 to December 2015 were retrospectively analyzed. Results In 29 children, 10 cases were idiopathic 19 cases were secondary and 11 cases occurred after infections. The main clinical manifestations were pallor, jaundice, dark urine, and hepatosplenomegaly. 21 cases were Coombs test positive. In 29 children, 22 cases had a good response to adrenocortical hormone therapy while in 7 cases which had not response to adrenocortical hormone, good efficacy was achived after combined with the gamma globulin treatment. Conclusions The first line drug for autoimmune hemolytic anemia treatment is adrenocortical hormone. The gamma globulin can improve the efficacy.

    • 摘要: Thrombotic thrombocytopenic purpura ( TTP) is a rare hematological emergency, which involves multiple systems, so clinical manifestations of TTP patients are diverse and complicated.Moreover, there is no specific criteria for the diagnosis of TTP.This paper reported the clinical manifestations, laboratory findings, management and outcomes of 21 patients with TTP.These patients all had acquired TTP, and 19 cases were idiopathic TTP.Initial symptoms involved various systems, with triad found in 19 cases (90.5%) and triad combined with renal function damage found in 5 cases (23.8%).ADAMTS13 activity was detected in 10 patients, of which 9 cases ( 90%) decreased.Of 14 cases with plasma exchange, 11 cases (78.6%) had remission, but of 7 cases without plasma exchange, only one patient survived.In the case of patients with Coombs test negative hemolytic anemia and thrombocytopenia, the possibility of TTP should be considered, especially those patients with neuropsychiatric symptoms, and the detection of ADAMTS13 is helpful for diagnosis.Early diagnosis and early administration of plasma exchange are the guarantee for good prognosis in patients with TTP.%血栓性血小板减少性紫癜( TTP)是临床较为少见的血液系统急症,多系统受累,临床表现呈现多样化、复杂化,缺乏特异性的诊断标准。本文报道了21例TTP患者的临床表现、实验室检查结果、治疗及转归。21例均为获得性TTP,其中19例属特发性,首发症状涉及多个系统,三联症者19例(90.5%),三联症伴肾功能损害者5例(23.8%);10例中9例(90%)血管性血友病因子裂解酶( ADAMTS13)活性降低;14例行血浆置换者11例(78.6%)缓解出院,7例未行血浆置换者只1例存活。急诊遇到Coombs试验阴性的溶血性贫血和血小板减少时,即应考虑TTP的可能,尤其是合并有神经精神症状者, ADAMTS13检测有助于诊断。早期诊断并尽早给予血浆置换治疗,是急诊TTP患者良好预后的保证。

    • 摘要: 自身免疫性溶血性贫血(AIHA)是临床最常见的获得性溶血性疾病之一,是由于机体产生针对自身红细胞抗原的抗体而导致的溶血.该病患者多伴有Coombs试验呈阳性,亦有少部分患者呈阴性.本文主要聚焦于AIHA患者Coombs试验呈阴性的成因、提高Coombs试验灵敏度的策略以及对Coombs 试验呈阴性AIHA患者的现代认识,旨在提高对此类疾病的认识,给临床诊疗提供帮助.
