摘要

目的 在患有尿素循环障碍(UCD)和新生儿疾病的患者中,通过持续肾脏替代疗法进行体外排毒被认为是除代谢紧急治疗外解决高血氨症失代偿的首选治疗方法。我们进行了一项回顾性比较分析,评估了初始透析对 UCD 患者生存期和神经认知结果参数的治疗效果,并与严重程度调整后的非透析对照组进行了比较。根据最近建立并验证的基因型特异性疾病预测模型进行分层,对108名患有男性鸟氨酸转氨酶缺乏症(mOTC-D)、瓜氨酸血症1型(CTLN1)和精氨酸琥珀酸尿症(ASA)的严重表型患者进行了调查。然而,在 CTLN1 中观察到初始透析后存活率有所提高,而在 ASA 中则有提高存活率的趋势。在幸存者中,透析组和非透析组每年发生(后续)代谢失代偿的频率没有差异。此外,初始透析治疗与神经认知结果的改善无关。 本严重程度调整比较分析显示,初始透析的一般做法既与 mOTC-D 患者生存率的改善无关,也与所调查的 UCD 亚型的神经认知结果无关。不过,初次透析可能会对 CTLN1 和 ASA 患者的生存率有利:UCDC 数据库记录在美国国家医学图书馆 (https://clinicaltrials.gov) 中。

Severity-adjusted evaluation of initial dialysis on short-term health outcomes in urea cycle disorders

Objective

In individuals with urea cycle disorders (UCDs) and neonatal disease onset, extracorporeal detoxification by continuous kidney replacement therapy is considered the therapeutic method of choice in addition to metabolic emergency treatment to resolve hyperammonemic decompensation. However, the indications for the initiation of dialysis are heterogeneously implemented transnationally, thereby hampering our understanding of (optimal) short-term health outcomes.

Methods

We performed a retrospective comparative analysis evaluating the therapeutic effects of initial dialysis on survival as well as neurocognitive outcome parameters in individuals with UCDs in comparison to a severity-adjusted non-dialyzed control cohort. Overall, 108 individuals with a severe phenotype of male ornithine transcarbamylase deficiency (mOTC-D), citrullinemia type 1 (CTLN1) and argininosuccinic aciduria (ASA) were investigated by stratification based on a recently established and validated genotype-specific disease prediction model.

Results

Mortality is associated with the height of initial peak plasma ammonium concentration, but appears to be independent from treatment with initial dialysis in mOTC-D. However, improved survival after initial dialysis was observed in CTLN1, while there was a trend towards improved survival in ASA. In survivors, annual frequency of (subsequent) metabolic decompensations did not differ between the dialyzed and non-dialyzed cohorts. Moreover, treatment with initial dialysis was not associated with improved neurocognitive outcomes.

Interpretation

The present severity-adjusted comparative analysis reveals that general practice of initial dialysis is neither associated with improved survival in individuals with mOTC-D nor does it differ with regard to the neurocognitive outcome for the investigated UCD subtypes. However, initial dialysis might potentially prove beneficial for survival in CTLN1 and ASA.

Clinical trial registration: The UCDC database is recorded at the US National Library of Medicine (https://clinicaltrials.gov).
