Abstract

Introduction: Chronic kidney disease (CKD) poses a global public health challenge, necessitating accurate assessment of renal function for timely intervention. Glomerular filtration rate (GFR) is a crucial indicator, traditionally measured using creatinine-based equations. However, Cystatin C-based equations offer potential advantages. We aim to evaluate the performance of estimated GFR (eGFR) equations for accurate renal function assessment in diverse Asian populations.

Materials and methods: Following PRISMA guidelines, the systematic review covered studies from 1991 to 2023 across Asian populations, incorporating equations based on both creatinine and Cystatin C. Eligibility criteria included adults aged 18 or older, either healthy or with CKD. Data extraction included study details, population characteristics, disease conditions, and formulas used. Quality assessment was conducted using the QUADAS-2 tool.

Results: The study analysed 26 studies focusing on South Asia and 66 on East Asia. In South Asia, the CKD-Epi-Pak equation demonstrated superior accuracy, achieving high percentages of eGFR values within specified ranges of measured GFR (P15: 70.39%, P30: 89.35%) with minimal bias (-1.33). The traditional MDRD equation exhibited poor performance, registering the lowest agreement percentages (P15: 7.8%, P30: 25.4%, P50: 71.1%) and the highest bias (-26.13). In East Asia, the CKD-Epi-2021 formula displayed the best accuracy, with high percentages of eGFR values within specified ranges (P15: 65.4%, P30: 97.6%). The simplified MDRD formula showed suboptimal performance, indicating lower agreement percentages (P15: 15.46%, P50: 56.59%). Variations of the MDRD formula in Japan exhibited bias while modified Gates Method demonstrated inferior precision.

Conclusion: CKD-Epi-Pak and CKD-Epi-2021 show potential suitability in South and East Asia, respectively. Future research should prioritise ethnicity-specific equation development to enhance accuracy and clinical utility in Asian populations.

估计肾小球滤过率(eGFR)方程在亚洲的性能评价:系统综述。
慢性肾脏疾病(CKD)是一个全球性的公共卫生挑战,需要准确评估肾功能以及时干预。肾小球滤过率(GFR)是一个重要的指标,传统上使用基于肌酐的方程来测量。然而,基于胱抑素c的方程提供了潜在的优势。我们的目的是评估估计GFR (eGFR)方程在不同亚洲人群中准确评估肾功能的性能。材料和方法:遵循PRISMA指南,系统评价涵盖了1991年至2023年亚洲人群的研究,纳入了基于肌酐和胱氨酸抑制素c的方程。入选标准包括18岁及以上的成年人,健康或患有CKD。数据提取包括研究细节、人群特征、疾病状况和使用的公式。使用QUADAS-2工具进行质量评估。结果:该研究分析了26项南亚研究和66项东亚研究。在南亚,CKD-Epi-Pak方程显示出卓越的准确性,在特定的GFR测量范围内(P15: 70.39%, P30: 89.35%)获得高百分比的eGFR值,偏差最小(-1.33)。传统的MDRD方程表现不佳,一致性百分比最低(P15: 7.8%, P30: 25.4%, P50: 71.1%),偏差最高(-26.13)。在东亚,CKD-Epi-2021公式显示出最好的准确性,在规定范围内eGFR值的百分比很高(P15: 65.4%, P30: 97.6%)。简化后的MDRD公式表现为次优,一致性百分比较低(P15: 15.46%, P50: 56.59%)。日本MDRD公式的变化存在偏差,修正的Gates法精度较差。结论:CKD-Epi-Pak和CKD-Epi-2021分别在南亚和东亚具有潜在的适用性。未来的研究应优先考虑种族特异性方程的开发,以提高亚洲人群的准确性和临床实用性。

期刊介绍: The Malaysian Journal of Pathology is the official journal of the College of Pathologists, Academy of Medicine Malaysia. The primary purpose of The Journal is to publish the results of study and research in Pathology, especially those that have particular relevance to human disease occurring in Malaysia and other countries in this region. The term PATHOLOGY will be interpreted in its broadest sense to include Chemical Pathology, Cytology, Experimental Pathology, Forensic Pathology, Haematology, Histopathology, Immunology, Medical Microbiology and Parasitology. The Journal aims to bring under one cover publications of regional interest embracing the various sub-specialities of Pathology. It is expected that the articles published would be of value not only to pathologists, but also to medical practitioners in search of a scientific basis for the problems encountered in their practice, and to those with an interest in diseases which occur in the tropics.
