Clinical Spectrum and Renal Outcome of Cryoglobulinemia in Hong Kong.

Hepatitis B is a common cause of cryoglobulinemia in southeast Asia, and the presence of cryoglobulinemia is associated with a worse renal event-free survival. The renal prognosis of cryoglobulinemia appears to be affected by the underlying cause, with hepatitis B having a worse renal outcome and patients with paraproteinemia having a worse overall survival than those with other causes of cryoglobulinemia.
