This article analyzes the data of four families with mutations of the GLA (galactosidase) gene with a special focus on the clinical presentation, diagnosis, and interdisciplinary clinical management of Fabry disease (FD) and enzyme replacement therapy (ERT) treatment, and has the aim to assess more accurate prevention and treatment strategy.
The MSSI (Mainz Severity Score Index) scale was used to evaluate the clinical data of five children diagnosed in our hospital, and the genotypes of all the patients with FD were collected. Two of the male children started ERT. We summarize the clinical effect and the evaluation of globotriaosylsphingosine (Lyso-GL-3) before and after treatment.
Five children were confirmed as having FD using the family histories, clinical manifestations, -galactosidase A (a-Gal A) activity, and genetic test results. Two children used agalsidase every 2 weeks regularly, after ERT. Their clinical symptoms improved, their pain intensity was significantly relieved, and upon re-examination their Lyso-GL-3 decreased conspicuously and no serious adverse reactions occurred. We report for the first time four families with children with FD. The youngest child was only 1 year old. The four families included one girl which is rare in X-linked lysosomal storage diseases.
The clinical phenotype of FD in childhood is nonspecific, and the misdiagnosis rate is high. Most children with FD have a delayed diagnosis, and their organs are often seriously damaged in adulthood. Pediatricians must improve their diagnosis and treatment awareness, screen high-risk groups, and emphasize multidisciplinary cooperation and holistic lifestyle management after diagnosis. The diagnosis of the proband is also conducive to the mining of other cases of FD families and has important guiding significance for prenatal diagnosis.
本文分析了四个伴有GLA(半乳糖苷酶)基因突变的家庭的数据,特别关注法布里病(FD)的临床表现、诊断、跨学科临床管理以及酶替代疗法(ERT)治疗,旨在评估更准确的防治策略。
采用美因茨严重程度评分指数(MSSI)量表评估我院确诊的5例患儿的临床资料,收集所有法布里病患者的基因型。其中2例男童开始接受ERT治疗。总结治疗前后的临床疗效及对Globotriaosylsphingosine(Lyso-GL-3)的评估。
根据家族史、临床表现、α-半乳糖苷酶A(α-Gal A)活性及基因检测结果,确诊5例患儿患有法布里病。2例患儿规律每2周使用阿加糖酶进行ERT治疗后,临床症状改善,疼痛强度明显缓解,复查时Lyso-GL-3显著下降,未发生严重不良反应。首次报道四个有法布里病患儿的家庭。最小患儿仅1岁。四个家庭中有1名女孩,这在X连锁溶酶体贮积病中较为罕见。
儿童法布里病的临床表型不具有特异性,误诊率高。多数法布里病患儿诊断延迟,成年后器官常严重受损。儿科医生必须提高诊治意识,筛查高危人群,强调诊断后的多学科合作及整体生活方式管理。先证者的诊断也有利于挖掘法布里病家庭的其他病例,对产前诊断具有重要指导意义。
