概括
多发性硬化症 (MS) 的利图西马布治疗导致免疫球蛋白G (IgG) 水平的剂量依赖性下降. 然而,这种下降并没有增加MS患者接受抗生素治疗的感染风险.
科学领域:
- 免疫学 免疫学 免疫学
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
背景情况:
- 利图西马布是一种用于治疗多发性硬化症 (MS) 的B细胞消耗疗法.
- 人们担心,由于Rituximab诱导的免疫球蛋白G (IgG) 降低,感染风险存在.
研究的目的:
- 为了评估用Rituximab治疗的现实世界MS队列中的IgG动态和抗生素使用.
- 评估接受Rituximab的MS患者IgG水平与感染风险之间的关系.
主要方法:
- 10年来对多发性硬化症患者进行的回顾性队列研究.
- 包括≥2次Rituximab输注和≥6个月随访的患者.
- 长度记录IgG水平和抗生素处方.
主要成果:
- 平均IgG在五年内从11.5g/L下降到9.0g/L (0.35g/L/年下降).
- 在7.5%的患者中观察到低胺环球蛋白血症 (<6.7 g/L).
- 较低的IgG水平并不能显著预测抗生素处方风险.
结论:
- 在MS患者中,利图西马布会诱导显著的,剂量依赖的IgG下降.
- 这种IgG下降与抗生素治疗感染的增加无关.
- 表明IgG水平和功能性免疫之间存在分离;支持继续使用Rituximab并进行监测.

Prescription, Nonprescription and Orphan Drugs
1.2K
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Immunoglobulin-like Cell Adhesion Molecules
4.3K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Relative Risk
2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Dynamic Equilibrium
62.0K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Development of Antibiotic Resistance
1.4K
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
