The Status Quo and Prospects of Diagnosis and Treatment of Rare Kidney Disease in Children / 罕见病研究

Rare kidney diseases are important causes of chronic kidney disease (CKD) in children. The majority of rare kidney diseases in children are hereditary kidney diseases, accounting for about 29.7% to 52.1% of children with CKD. Next-generation sequencing has been widely used in clinical diagnosis in the past decade, leading to the improvement of the diagnosis of hereditary kidney diseases. In 2018, China announced the first list of rare diseases and greatly enhanced the diagnosis, treatment and research of rare diseases in China, including rare kidney disease. Meanwhile, China faces great challenges in the diagnosis and treatment of hereditary kidney diseases in Children, including the assessment of pathogenicity of gene variants, the lack of biomarkers for disease progression and therapy efficacy, lack of drugs, and others. The future lies in the cooperation between patients, physicians, researchers, and health policy markers, and the fast translation from research finding to clinical application, so as to meet the demand from the children with rare kidney diseases in China.

Study on establishment of an on－line registry of hereditary kidney diseases in children / 中华实用儿科临床杂志

Objective To explore the feasibility of establishing such an on_line registry of hereditary kidney diseases in Chinese children. Methods Selecting disease categories,designing input parameters,data quality and secu_rity are key factors of establishing an on_line registry of hereditary kidney diseases including general information,clini_cal data,relevant examinations,genetic testing,medication and follow_up. Results The first on_line,multi_cen_tered registry of children with hereditary kidney diseases in China was established using Java language and MySQL data_base. It contained 1 580 parameters and covered 6 major hereditary kidney diseases including Alport syndrome,protei_nuria related kidney disease,renal tubular disease,renal cystic disease,congenital anomalies of kidney and urinary tract and other hereditary kidney diseases. To date,a total of about 2 200 families from 32 tertiary hospitals have been regis_tered. About 648 families have well_documented follow_up records with a maximum follow_up of 13. 5 years. The registration system has data screening,export and simple statistical functions. The registry system had a clear interface, and was convenient and friendly to use. The input data could be real_time updated,and dedicated personnel was re_sponsible for data review and quality control to ensure security and reliability. Conclusions The on_line registry of children with hereditary kidney diseases not only facilitates standardized management of patients. Moreover,it provides a platform and a good foundation for the establishment and expansion of clinical research cohort.
