paraproteinemias/triglyceride

In the present report we describe a patient with multiple myeloma and long-standing paraproteinemia who developed xanthoma in the absence of an elevation in plasma cholesterol or triglyceride concentrations. Studies demonstrated that our patient's monoclonal IgG antibody interacted with apoprotein

Type III hyperlipidemia is a rare metabolic disorder characterized by elevated plasma concentrations of cholesterol and triglycerides. In subjects homozygous for the isoform E2 of apoprotein E, the disease becomes manifest when other factors that interfere with normal lipoprotein metabolism are

This report describes a patient with advanced planar xanthomatosis and benign monoclonal gammopathy who had normal plasma concentrations of cholesterol and triglycerides (TG). Decreased electrophoretic mobilities of very low density lipoprotein (VLDL), intermediate density lipoproteins (IDL) and

Autoimmune hyperlipidemia (AIH) may be induced a variety of antibodies which inhibit different stages of the lipolytic process by which the lipid load is removed from the circulating lipoproteins. In a patient having a monoclonal gammopathy and a nephrotic syndrome with a glomerulonephritis and a

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis

OBJECTIVE To assess the frequency of additional causes of distal sensory polyneuropathy (DSP) in patients with diabetes mellitus (DM). METHODS Retrospective review of patients with DM and DSP during a 5 year period. A quantitative sensory score (QSS) was determined at the initial evaluation and

When very low or undetectable high density lipoprotein (HDL)-cholesterol (HDL-C) is encountered in clinical practice, a paraproteinemia should be suspected in the absence of genetic or more obvious secondary causes. We reported a case of artifactually low HDL-C in a 68-year-old man with a past

A case of necrobiotic xanthogranuloma without typical periorbital involvement is described at the ultrastructural level. The patient, a 58-year-old Italian man, presented in 1995 with a brief history of nodulo-papular lesions commencing on the lower limbs, and mild paraproteinemia. During 6 years of

A patient who developed diffuse normolipidemic plane xanthomas also presented with IgG lambda monoclonal gammopathy, hypernephroma, an unusual family cluster of leukemia (with two family members in two generations), and a unique, acquired C1-esterase inhibitor deficiency. A second patient presented

Primary intestinal lymphangiectasia (PIL), also known as Waldmann's disease, is a rare disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and

We evaluated a new liquid homogeneous assay for the direct measurement of high density lipoprotein cholesterol (HDL-C Plus) in seven laboratories. The assay includes two reagents which can be readily used in most available clinical chemistry analyzers. The total CVs of the new method were below 4.6%

Decreased high-density lipoprotein cholesterol (HDL-C) levels have been designated a major risk factor for cardiovascular disease, and there is considerable interest in identifying individuals with these abnormalities for appropriate management. Although low HDL-C may result from genetic factors, it
