The most common cause of mixed cryoglobulinemia is hepatitis C virus (HCV), while other infections including hepatitis B virus (HBV) and HIV infections, lymphoproliferative and autoimmune disorders have also been associated with the disease. We reported a rare case of type II-III mixed cryoglobulinemia caused by alcoholic cirrhosis. We need to increase the awareness of and facilitate the earlier identification of mixed cryoglobulinemia in our clinical work, when encountering a patient with liver cirrhosis combined with renal impairment so that treatment can begin early, to improve the success rate of therapy and reduce the fatality rate in potentially life-saving therapy.
