概括

这项研究详细介绍了一种罕见的淋巴细胞性淋巴瘤 (LPL) 病例,该淋巴瘤产生的Bense Jones (BJ) 蛋白质,而不是典型的IgM M蛋白质. 用提拉布鲁丁尼治疗显示,患者的功能显著改善.

科学领域:

血液学血液学血液学
在瘤学瘤学.
腎臟病學 (nephrology) 是一種醫學專業.

背景情况:

淋巴细胞性淋巴瘤 (LPL) 是一种低级B细胞淋巴瘤,经常与沃尔登斯特罗姆巨型球蛋白血症和IgM M蛋白有关.
不典型的LPL表现,例如Bense Jones (BJ) 蛋白质的产生,很少见.

研究的目的:

报告LPL产生卡帕类型Bense Jones (BJ) 蛋白质的第一个已记录的病例.
描述这种独特的LPL病例的临床表现,诊断工作和治疗反应.

主要方法:

一个78岁的女性患者的病例报告,表现为疲劳和蛋白尿.
诊断程序包括血液免疫固定,尿液BJ蛋白质分析,脏活检,骨髓检查和MYD88突变测试.
治疗包括提拉布鲁替尼,随访评估尿蛋白水平.

主要成果:

患者在尿液中呈现了卡帕型BJ蛋白,血液中没有检测到的M蛋白.
脏活检显示淋巴细胞和血细胞透与卡帕轻链限制.
骨髓检查显示未成熟的血细胞淋巴细胞具有轻链限制和MYD88突变.
用提拉布鲁替尼治疗导致蛋白尿症在六个月内显著改善.

结论:

这一案例突出显示了一种不寻常的LPL表现,涉及BJ蛋白质的产生和内透.
提拉布鲁替尼在治疗这种罕见的LPL与脏干扰的形式方面表现出高效.
对LPL患者进行密切监测是必不可少的,这些患者呈现BJ蛋白和损害.

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
