Abstract

Background.

A 29-year-old white woman with a family history of Fabry disease was referred to a nephrology clinic with hypertension and nephropathy. Her renal function was below normal (serum creatinine level 141 μmol/l; estimated glomerular filtration rate 41 ml/min/1.73 m2) with no proteinuria or albuminuria.

Investigations.

Medical history, physical examination, leukocyte α-galactosidase A assay, laboratory tests (for antinuclear antibodies, antineutrophil cytoplasmic antibodies, lupus anticoagulant, anticardiolipin antibodies, complement and cryoglobulin), ophthalmological examination, echocardiography, brain magnetic resonance angiography, renal ultrasonography, renal color echo-Doppler scan, renal magnetic resonance angiography, renal angiography and renal biopsy.

Diagnosis.

Diffuse sclero-atrophic renal tissue changes and widespread renal arterio-arteriolosclerotic changes secondary to Fabry disease.

Treatment.

Angiotensin-converting-enzyme inhibitors and maintenance treatment with agalsidase-β, 1 mg/kg body weight, every 2 weeks.
