OBJECTIVE Heavy post-transplant immunosuppression may contribute to long-term immunosuppression dependence by subverting tolerogenic mechanisms; thus, we sought to determine if this undesirable consequence could be mitigated by pretransplant lymphoid depletion and minimalistic post-transplant monotherapy. STUDY DESIGN Lymphoid depletion in 17 unselected(More)
Five methods of assessing blood in urine were studied and compared: sedimentation count, hemacytometry, "Clini-lab" reagent strip and "N-Multistix" and "ChemStrip-8" dipsticks. The minimum sensitivity of two commercially available urine dip-stick procedures for blood was established. The study includes method association, assay variation among and within(More)
We measured creatine kinase (EC activity in 1009 serum samples from 538 patients in the intensive-care units of the University of Texas Medical Branch hospitals. Creatine kinase isoenzymes migrating cathodal to skeletal muscle creatine kinase (CK-MM) on cellulose acetate electrophoresis were found in sera from 14 of the 538 patients. Creatine(More)
The procedure used with the Du Pont aca for alpha-amylase (1,4,-alpha-D-glucan glucanohydrolase, EC was evaluated in our laboratory and compared with the Roche Diagnostics "Amylochrome" and Perkin-Elmer Coleman 91 amylase assays. The within-run coefficients of variation (CV) for samples of fresh normal sera were: aca 5.8% and 4.3% on two different(More)
Two urine dip-stick assays for glucose were studied and compared to a quantitative hexokinase procedure. We determined sensitivity, specificity, predictive value of "normal" and "abnormal" dip stick results, assay efficiency, technologist precision, and method association. Precision was poor. Attempts to estimate urine glucose concentration with the dip(More)
Coronary artery calcification has long been known to be associated with atherosclerosis and is intimately associated with atherosclerotic plaque development. Similarly, aortic valve degeneration and calcification appears to follow a pathophysiologic process very similar to atherosclerosis. Newer noninvasive technologies such as Electron Beam Tomography(More)
Four commercial products for urine glucose determination were evaluated and compared with a quantitative hexokinase procedure. We examined precision, sensitivity, and analytical recovery of glucose from glucose-supplemented urine samples and comparison of methods, using patients' samples. Only "Chemstrip uG" (Bio-Dynamics Inc.) could differentiate between(More)
Two dipstick procedures and an automated quantitative urinary nitrite assay were used to study nitrite in 786 samples of urine submitted to the bacteriology laboratory for routine culture and sensitivity testing. Many samples that had more than 100,000 nitrite-reducing organisms/ml and no detectable nitrite were studied. Limited nitrate concentration in(More)
We studied and compared results of two urine dip-stick procedures for protein with those of quantitative measurements of total protein and albumin in urine. Sensitivity, specificity, and predictive value of "normal" and "abnormal" dip-stick results, assay efficiency, technologist precision, and method association were determined. Precision was poor,(More)
