概括

脊椎肌肉缩 (SMA) 患者表现出功能受损和慢性病的风险. 对SMA的遗传疗法没有改善清除,这表明SMN蛋白质缺乏症会对脏健康产生长期影响.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
遗传学遗传学是一个
神经学神经学

背景情况:

脊椎肌肉缩 (SMA) 是由于SMN1基因功能丧失和SMN蛋白质缺乏导致的.
虽然基因疗法可以改善SMA的运动功能,但它们对脏等其他器官的影响尚不清楚.

研究的目的:

在开始基因疗法之前和之后对SMA患者的功能进行纵向评估.
研究SMN蛋白质缺乏对脏健康的影响以及SMN2-拼接修饰疗法的影响.

主要方法:

在263名SMA患者 (1c-4型) 中,使用血清囊C eGFR对功能进行长度评估.
评估管状功能障碍标志物 (低血,蛋白尿) 和结石/结石病史.
分析治疗后的功能变化 nusinersen 或risdiplam.

主要成果:

19%的SMA患者的EGFR<90毫升/分钟/1.73米2,表明慢性病风险;3.5%的EGFR<60毫升/分钟/1.73米2.
管管功能障碍症状 (低血,蛋白尿) 是普遍存在的 (51.7%,22%).
尽管接受了治疗,但囊素C eGFR 继续下降,尽管低血清症有所改善.

结论:

肌痛性脊髓炎患者面临脏清理受损和慢性病的显著风险.
在SMA患者中,SMN2拼接修饰疗法无法恢复功能.
缺少SMN蛋白直接影响脏健康,可能导致长期并发症.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Factors Affecting Renal Clearance: Renal Impairment

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
