We studied the extent and pattern of increased cardiac troponin T (cTnT) concentrations in 174 hemodialyzed patients. cTnT concentrations were above 0.10 and 0.20 microg/L in 29% and 10% of patients, respectively. In patients without acute coronary disease, the highest value observed was 3.2 microg/L. cTnT increased after dialysis in 10 of 12 patients, with(More)
The importance of hypertriglyceridemia as an independent predictor of coronary artery disease (CAD) remains unsettled. Hypertriglyceridemia, with or without associated hypercholesterolemia, occurs more frequently in premature CAD subjects than does hypercholesterolemia alone. With univariate analysis, most studies show a positive correlation between plasma(More)
It has been proposed that remnants of chylomicrons and very-low-density lipoproteins (VLDL) are atherogenic. We have used an immunochemical method to isolate remnant-like particles (RLP) and measured them in terms of their cholesterol and triglycerides (TG). RLP consist of apoB-48-containing triglyceride-rich lipoproteins and remnant-like VLDL containing(More)
BACKGROUND Spurious increases in serum troponins, especially troponin T, have been reported in patients with and without acute myocardial syndromes. METHODS We studied 78 autopsied patients without clinical myocardial infarction (MI) and correlated histologic cardiac findings with antemortem serum creatine kinase (CK), its MB isoenzyme (CK-MB), cardiac(More)
OBJECTIVE To establish reference intervals for serum free testosterone for DPC's Free Testosterone assay. METHODS We used data from healthy subjects and patients to determine reference intervals by parametric and non-parametric methods after partitioning by sex and age. RESULTS In males, there was a significant decrease in free testosterone(More)
A 51-year-old man developed a large retroperitoneal tumor with liver and lymph node metastases; there was no radiological evidence of pancreatic involvement. Despite the progression of disease, results of laboratory tests, notably serum amylase, were normal except for minor increases in aspartate aminotransferase and gamma-glutamyltransferase and a marked(More)
Serum osteocalcin, a marker of bone osteoblast function, has been shown to be sensitive to even low doses of oral glucocorticoids. The effect of 1 wk of inhaled glucocorticoid therapy with budesonide (200 micrograms/puff), beclomethasone dipropionate (250 micrograms/puff), and placebo at two puffs b.i.d. and four puffs b.i.d. on 0900 serum osteocalcin were(More)
BACKGROUND Increased plasma troponin T (cTnT), but not troponin I (cTnI), is frequently observed in end-stage renal failure patients. Although generally considered spurious, we previously reported an associated increased mortality at 12 months. METHODS We studied long-term outcomes in 244 patients on chronic hemodialysis for up to 34 months, correlating(More)
OBJECTIVES To determine the significance of elevated serum troponin T (cTnT) occurring in hemodialysis patients in the absence of clinical evidence of acute coronary ischemia. DESIGN AND METHODS Twelve-month follow-up of cohort of 172 hemodialyzed patients with known serum cTnT concentration. The cohort consisted of patients undergoing hemodialysis in a(More)
OBJECTIVE High dose methotrexate (MTX) has been linked with bone loss in oncology patients. However, it is unclear whether longterm low dose MTX used in the treatment of inflammatory arthritis is associated with bone loss. We compared the effect of low dose MTX on bone density in prospectively recruited patients with rheumatoid arthritis (RA) and(More)
