The use of iohexol clearance to determine GFR in patients with severe chronic renal failure--a comparison between different clearance techniques.

Unlabelled: The nonionic low-osmolar contrast medium iohexol was used as marker of glomerular filtration rate (GFR) in 53 patients with stable renal function (group I: n = 32, group II: n = 21). All the patients had clearance values < or = 30 ml.min-1.

Hepatitis C virus infection in hemodialysis patients in southern Sweden: epidemiological, clinical, and diagnostic aspects.

A prevalence of hepatitis C virus (HCV) antibodies of 12% was found in 276 patients from 11 dialysis units. Between zero and 22% of the patients in the different units were anti-HCV positive. The epidemiology of HCV was studied in two units during a 2 year period by antibody assays and the polymerase chain reaction and correlated with clinical manifestations.

In vivo comparative evaluation of hemodialysis tubing plasticized with DEHP and TEHTM.

The migration of plasticizers from blood lines was studied in 11 patients with chronic renal failure on hemodialysis for a period of six months. Di-2-ethylhexylphthalate (DEHP), the conventional plasticizer, was compared with tri-2-ethylhexyltrimellitate (TEHTM). A liquid chromatography method for quantitative determination of DEHP and TEHTM in human blood plasma is described.
