概括

皮下免疫球蛋白 (SCIG) 和静脉注射免疫球蛋白 (IVIG) 在常见变性免疫缺陷 (CVID) 患者的自身免疫血小板缺陷 (AITP) 预防方面同样有效. 维持IgG水平超过7g/l对于预防CVID的AITP至关重要.

科学领域:

免疫学免疫学免疫学
血液学血液学血液学
药理学药理学是指药理学的学科.

背景情况:

自免疫性血小板缺血症 (AITP) 经常影响常见变性免疫缺陷 (CVID) 的患者.
静脉注射免疫球蛋白 (IVIG) 是CVID中AITP的常规初始治疗方法.
皮下免疫球蛋白 (SCIG) 提供了另一种治疗方式.

研究的目的:

为了比较SCIG与IVIG在预防成人CVID患者AITP发作方面的安全性和有效性.
在接受免疫球蛋白治疗的CVID患者中确定影响AITP发生的因素.

主要方法:

这是一项前性观察性研究,涉及47名患有AITP的成年CVID患者.
患者接受了SCIG (n=27) 或IVIG (n=20) 的治疗.
在64个月内对AITP发作进行了监测,通过特定的血小板计数值来定义.

主要成果:

12名患者 (25.5%) 经历了AITP发作 (7名在SCIG,5名在IVIG).
在SCIG和IVIG组之间没有发现AITP发生的显著差异 (p=0.99).
鉴定出IgG最低水平>7g/l是预防AITP的关键因素.

结论:

在CVID患者中,SCIG和IVIG在预防AITP方面表现得相当有效.
维持足够的IgG低谷水平对于管理有AITP的CVID患者至关重要.
在CVID中,SCIG代表了IVIG的可行替代方案,用于预防CVID中的AITP.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
