Cryoglobulins are immunoglobulins that precipitate in vitro at temperatures <37°C but that redissolve if heated; they are broadly divided into 3 classes. Cryoglobulinemia has a plethora of clinical manifestations, but it typically presents a vasculitic syndrome, most notably a triad of purpura,
A case report of a patient with essential cryoglobulinemia and episodes of angioedema caused by an acquired C1 inhibitor deficiency is presented. The patient had high levels of circulating immune complexes. In the course of complement activation C1 inhibitor may be consumed and the resulting C1
Purpose. To report a young male with unilateral central retinal vein occlusion (CRVO) associated with cryoglobulinemia. Case Presentation. A 33-year-old male without any known systemic or ocular disorder was admitted to our clinic with a complaint of visual loss for three days in his left eye. Based

Eosinophilic granulomatosis with polyangiitis (EGPA) is an antineutrophil cytoplasmic antibody- (ANCA-) associated small vessel vasculitis with multisystem involvement. It is characterized with asthma, eosinophilia, and renal and peripheral nervous system involvement. However, EGPA
We reported a case of type II cryoglobulinemia involving glomerulopathy associated with HCV-induced liver cirrhosis. The patient was a 57-year-old woman. Her past history included chronic hepatitis at 51 years and rheumatoid arthritis at 53 years of age. At 46 years, an erythematous lesion appeared
An 81-year-old man was admitted to our hospital because of leg edema. Serological studies for anti-neutrophil cytoplasmic antibody (ANCA), anti-double stranded DNA antibodies, and antibodies to hepatitis C and B were negative. Severe hypocomplementemia was present and a cryoglobulin was detected
In recent years, several laboratories have suggested that chronic hepatitis C virus (HCV) infection is strongly associated with type II cryoglobulinemia (CG) and/or membranoproliferative glomerulonephritis (MPGN). We report here a case of MPGN due to type II CG probably associated with chronic HCV
Ehrlichiosis is a tick-borne disease with diverse clinical presentations, ranging in severity from a flu-like illness with fever and myalgias to a serious systemic disease with multisystem organ failure. Nephrotic syndrome has been reported previously in two cases of human ehrlichiosis. A kidney
Two patients with essential cryoglobulinemia, an immune complex disease, developed an intense, chronic, monoarticular knee synovitis. In each patient, synovial fluid findings (high white count and left shift) suggested a pyrogenic or crystalline etiology. A synovectomy was eventually performed in
Many patients with type II mixed cryoglobulinemia have been shown to be infected with hapatitis C virus (HCV). Therefore, interferon-alfa has become the first choice of treatment for patients with HCV-associated cryoglobulinemia. However, the disease often relapses after the discontinuation of
A 65-year-old male patient with nephrotic syndrome was admitted to our hospital due to worsening systemic edema and purpura on the limbs. He had an impaired renal function, low serum complement level, and elevated rheumatoid factor level. He was positive for cryoglobulin (monoclonal IgM-κ and
BACKGROUND
Laboratory tests play a central role in assessing a patient and orienting the diagnostic evaluation. We report a case where the discrepancy between the manual and automatic cell count gave a hint to the final diagnosis.
METHODS
A 55-year-old Caucasian man, known to have hepatitis C, was
A 65-year-old-woman presented with edema, ascites, proteinuria and abnormal liver function tests. A small amount of mixed cryoglobulin was detected in her serum. Liver biopsy revealed mild chronic active hepatitis, but tests for hepatotropic viral infection were negative. Electron microscopy of the
Direct antivirals showed dramatic response in hepatitis C virus (HCV) eradication, but their effect on extrahepatic manifestations is still unclear. A 49-year-old woman was referred to us suffering from lower limb edema and frothy urine. Renal biopsy was done and she was diagnosed with HCV-related
