precipitate levels (<50 milligram/liter of fibrinogen) and do not have a disorder associated with the development of cryofibrinogenmia. Associated disorders Cryoglobulinemia may occur without evidence of an underlying associated disorders, i.e. primary cryoglobulinemia (also termed essential cryoglobulinemia) or, far more commonly, with evidence of an underlying disease, i.e. secondary cryoglobulinemia. Secondary cryofibrinogenemia can develop in individuals with infection (~12% of cases), malignant or premalignant disorders (21%), vasculitis (25%), and autoimmune diseases (42%). In these cases of the secondary disorder, cryofibrinogenemia may or may not cause tissue injury and/or other symptoms and the actual cause-effect relationship between these diseases and the development of cryofibrinogenemia is unclear. Cryofibrinogenemia can also occur in association with the intake of certain drugs. Infection-associated cryofibrinogenemia Acute bacterial and mycobacterium infections are sometimes associated with cryofibriongenemia. In these cases, cryofibrinogenemia is usually transient and rapidly resolves after appropriate anti-bacterial treatment. In HIV/AIDS virus, Epstein–Barr virus, cytomegalovirus, varicella zoster virus, herpes simplex virus, and hepatitis virus infections any rise in circulating cryofibrinogen is more sustained and potentially symptomatic. For example, one large study of the most thoroughly study example of viral infection-associated cryofibrinogenmia, Hepatitis C infection, found that cryofibrinogenemia occurred in 37% of cases, was associated with concurrent cryoglobulinemia in 89% of cases, and led to significantly increased vascular disruption. Antiviral therapy resulted in complete resolution of the cryofibrinogenemia in only ~50% of these cases. Malignancy-associated cryofibrinogenemia Lymphoproliferative disorders such as B-cell lymphomas, T-cell lymphomas, chronic lymphocytic leukemia, and various plasma cell dyscrasias (e.g. multiple myeloma, Waldenström's macroglobulinemia, and the premalignant precursors to these two diseases, MGUS, smoldering multiple myeloma, IgM MGUS, and smoldering Waldenström's macroglobulinemia as well as adenocarcinomas of the stomach, liver, lung, colon, and other solid tumor cancers have been reported to be associated with symptomatic or asymptomatic cryfibrinogenemia. Vasculitis-associated cryofibrinogenemia Cryofibrinogenemia is often associated with inflammatory disease of the arteries and/or veins. These vasculitis-associated diseases include ANCA-associated vasculitides, giant cell arteritis, Behcet disease, polyarteritis nodosa, and Henoch–Schonlein purpura. Cryofibrinogenemia is also often associated with the inflammatory vasculitis that accompanies mixed Cryoglobulinemia#Classification, i.e. cryoglobulinemic vasculitis, particularly but not exclusively in instances where hepatitis C virus is an underlining disease. Autoimmune disease-associated cryofibrinogenemia A broad range of autoimmune diseases have been reported to be associated with cryofibrinogenemia. These diseases include systemic lupus erythematosus, Sjögren syndrome, rheumatoid arthritis, mixed connective tissue disease, polymyositis, dermatomyositis, systemic sclerosis, antiphospholipid antibody syndrome, Hashimoto disease, Graves' disease, sarcoidosis, pyoderma gangrenosum, spondyloarthropathy,
