[Renal damage during type I cryoglobulinemia]. / Atteinte rénale au cours des cryoglobulinémies de type I.

ABSTRACT

UNLABELLED CHARACTERISTICS OF THE RENAL DAMAGE Type I cryoglobulinemia, composed of a single monoclonal immunoglobulin, may be responsible for a glomerulopathy with clinical presentation and histological characteristics close to those of mixed cryoglobulinemia.
