Rapidly progressive renal failure to reveal LCAT deficiency in an Algerian family.

Lecithin-cholesterol acyltransferase (LCAT) deficiency is an autosomal recessive disorder that can reveal two different diseases: a very interesting nephrological picture of complete enzyme deficiency characterized by the association of dyslipidemia, corneal opacities, anemia, and progressive nephropathy; and a partial form (fish-eye disease) with dyslipidemia and progressive corneal opacities only. We report herein the case of a 35-year-old man who presented hypertension, renal symptomatology of rapidly progressive glomerulonephritis associates: nephrotic proteinuria, severe renal failure, in combination with annular corneal opacities, anemia, and dyslipidemia. The diagnosis of familial LCAT deficiency was confirmed by clinical examination, characteristic dyslipidemia, undetectable LCAT levels in plasma, and positive family history.
