Previous reports suggest cryoglobulinemia might influence the hepatitis C virus (HCV) infection clinical course and treatment response but this association has not been thoroughly evaluated. We aimed to assess the relationship between cryoglobulinemia and sustained viral response (SVR) in patients
IgE RF was measured by ELISA assay using aggregated IgG as a solid phase immunosorbent and alkaline phosphatase-conjugated Fc epsilon-specific monoclonal and polyclonal antibodies as indicators. The presence of IgE RF was defined in this assay as binding of the conjugate greater than 2.33 SD above
An enzyme-linked immunosorbent assay (ELISA) using wells coated with normal platelets has been tested in order to quantitate cell-bound immune complexes (ICs) by measuring the uptake of alkaline phosphatase-conjugated antibodies to IgG in the immune complexes. All patients with essential mixed
An 82-year-old woman with essential mixed cryoglobulinemia type II (IgM K IgG) presented with moderate renal failure and nephritic syndrome. Mesangiocapillary glomerulonephritis with mesangial and subendothelial granular deposits containing IgG, IgM, and C3 in conjunction with small-vessel
A study of liver abnormalities in 36 patients with mixed cryoglobulinemia in the absence of underlying infectious, connective tissue, or lymphoproliferative disorders revealed clinical or biochemical evidence of liver dysfunction in 84%. Hepatomegaly was detected in 77%, splenomegaly in 54%, and
Primary biliary cholangitis is an autoimmune biliary disease characterized by injury of bile ducts, eventually leading to cirrhosis and death. In most cases, anti-mitochondrial antibodies and persistently elevated serum alkaline phosphatase are the basis for the serological diagnosis. Malignant lymphocytes from 30 B-cell chronic lymphocytic leukemia (B-CLL) patients were studied for the cytochemical localization of two acid hydrolases, alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (AT). The large majority of the cells stained for both ANAE and AP in 7 cases, for AP
An association between mixed cryoglobulinaemia (MC) and hepatotropic viruses, chiefly hepatitis C virus (HCV), has been widely reported. The presence of HCV genomic sequences or HCV-related viral proteins in the serum, purified cryoglobulins, peripheral blood mononuclear cells and into several
The solid phase Cl1-binding assay has been adapted to an enzymatic micromethod in which alkaline phosphatase labeled soluble Staphylococcus aureus protein A is used in place of the second antibody. The assay, which is run in microtiter plates, provides a rapid, sensitive (0.030 mg/ml of human
