Abstract

Background: Antiphospholipid syndrome (APS) is a common form of acquired thrombophilia associated with a high thrombotic risk. Fabry's disease (FD) is an X-linked lysosomal storage disease caused by mutations in the alpha-galactosidase A (GLA) gene and presents with a wide range of clinical manifestations, including a high rate of thrombosis. Previously reported, 45% of FD patients were found to have antiphospholipid autoantibodies.

Objectives: To determine the prevalence of FD in patients with APS.

Methods: We conducted a prospective study. Data were collected from 41 APS patients at our outpatient clinic at Meir Medical Center in Israel. We utilized chemical and genetic analyses to identify FD among APS patients. Dried blood spot (DBS) was used to assess GLA activity in males, and mutational analysis of the GLA gene was performed by sequencing exons and their flanking regions in women.

Results: Among 41 antiphospholipid patients, one male patient was diagnosed with FD. Gal variants were not detected in any of the tested female patients.

Conclusions: We found a low prevalence (2.4%) of FD in APS patients. Larger studies are needed to evaluate the clinical utility and cost-effectiveness of routine FD screening in this population.

法布里病和抗磷脂综合征共存:一项前瞻性队列研究
背景:抗磷脂综合征(APS)是一种常见的获得性血栓病,具有较高的血栓形成风险。法布里病(FD)是一种由α -半乳糖苷酶A (GLA)基因突变引起的x连锁溶酶体贮积病,具有广泛的临床表现,包括血栓形成率高。先前报道,45%的FD患者被发现有抗磷脂自身抗体。目的:了解APS患者FD的患病率。方法:我们进行了前瞻性研究。数据来自以色列梅尔医疗中心门诊41例APS患者。我们利用化学和遗传分析来鉴定APS患者的FD。用干血斑法(DBS)评估男性GLA活性,通过测序女性GLA基因外显子及其侧翼区域进行突变分析。结果:41例抗磷脂患者中,1例男性患者被诊断为FD。Gal变异未在任何被检测的女性患者中检测到。结论:我们发现APS患者FD患病率较低(2.4%)。需要更大规模的研究来评估常规FD筛查在这一人群中的临床效用和成本效益。
