MRL-lpr/lpr mice spontaneously develop an autoimmune disease resembling systemic lupus erythematosus and rheumatoid arthritis. One of the unique serological abnormalities in this strain is remarkably high concentrations of cryoglobulins. Analysis of immunoglobulin components in their cryoglobulins has shown selective enrichment of a particular IgG subclass, IgG3. As IgG3 enrichment is also foun...
Cryoglobulin characteristics in chronic hepatitis C (CHC) might be of importance for knowing more about the pathogenesis and treatment of the disease. We aimed to investigate the relationship between cryoglobulin types and their specificity against hepatitis C virus (HCV) antigenic epitopes in CHC patients. We analyzed samples from 43 patients with HCV-associated cryoglobulinemia, of whom 4 had...
BACKGROUND The prevalence of hepatitis C virus (HCV) infection has been estimated at 43 to 84% in patients with essential mixed cryoglobulinaemia in recent large series. Some of these cases have been successfully treated with interferon-alpha. The objective was to evaluate the prevalence and the possible role of HCV infection in essential mixed cryoglobulinaemia. METHODS Fifteen patients (eig...
Cryogloculins were examined in a standardized manner in an unselected group of 35 patients with rheumatoid arthritis (RA) and 8 patients with RA complicated by cutaneous vasuclitis and neuropathy. Optimum conditions for detection and characterization of cryoglobulins were established; the proportion of resolubilized to total precipitable protein remained constant in an individual patient under ...
platelet plots are not always seen in cryoglobulinemia, although other interferences are usually detected with high efficiency. For comparison, whereas the Technicon H*3 appeared to provide a more immediate visual indication of sample cryoglobulins, large platelet count overestimates were still obtained in most cases. Examination of graphic plots is not used in all laboratories, and its efficie...
The sera of school children with Schistosoma haematobium infection were tested for the presence of cold-insoluble immune complexes "the cryoglobulins". Two different methods were used: the standard macro-technique and the micro-adaptation technique. On using the standard macro-technique, 40 (32.8%) out of 122 schistosomiasis patients and 6 (7.5%) out of 80 control children were positive for cry...
BACKGROUND Peripheral neuropathy is one most common, limiting and invalidating neurological symptom in subjects with hepatitis C virus and mixed cryoglobulinemia. Notably, the medical therapy proposed to eradicate HCV, can frequently exacerbate the painful neuropathy. Therefore, neuropathy therapies are insufficient and inadequate, and comprise immunosuppressive drugs, such as steroid or cyclos...
Cryoglobulinemia and mucosa-associated lymphoid tissue (MALT) lymphoma are diseases characterized by B-cell dysregulation and overproduction of antibodies. Vasculitis and cutaneous manifestations are common, but renal involvement is rare. A 65-year-old woman with type 1 cryoglobulinemia and MALT lymphomas of the right lacrimal and parotid glands successfully treated by excision and chemoradioth...
