Cryoglobulinaemic vasculitis: classification and clinical and therapeutic aspects

Cryoglobulinaemia may cause cutaneous vasculitis and
glomerulonephritis, potentially leading to end stage renal failure.
An important proportion of cryoglobulinaemias are secondary to
hepatitis C virus infection. Emerging antiviral treatment options
offer a chance for causal therapy of these cases of
cryoglobulinaemia. This review summarises the classification and
clinical and therapeutic aspects of cryoglobulinaemic vasculitis
and glomerulonephritis.
