Abstract

Background

Fabry disease is an X-linked recessive lysosomal storage disorder that provokes multi-organ morbidity, including early-onset stroke. Worldwide prevalence may be greater than previously estimated, with many experiencing first stroke prior to diagnosis of Fabry disease.

Aims

The aim of this study is to screen a cohort of stroke patients under 70 years of age, evaluating the clinical and economic efficacy of such a broad screening programme for Fabry disease.

Methods

All stroke patients under 70 years of age who were entered into the Saint Vincent’s University Hospital stroke database over a 6-month period underwent enzyme analysis and/or genetic testing as appropriate for Fabry disease. Patients’ past medical histories were analysed for clinical signs suggestive of Fabry disease. Cost-effectiveness analysis of testing was performed and compared to overall economic impact of young stroke in Ireland.

Results

Of 22 patients tested for Fabry disease, no new cases were detected. Few clinical indicators of Fabry disease were identified at the time of testing.

Conclusion

Broad screening programmes for Fabry disease are highly unlikely to offset the cost of testing. The efficacy of future screening programmes will depend on careful selection of an appropriate patient cohort of young stroke patients with multi-organ morbidity and a positive family history.
