Pharmacodynamics of practolol in chronic renal failure.

Plasma levels of practolol were measured in advanced chronic renal failure. The plasma half life was found to be markedly prolonged. During haemodialysis considerable shortening of the half life occurred. Therapeutic blood levels of practolol can be achieved in maintenance haemodialysis patients by the administration of 200 mg of the drug by mouth at the beginning and end of each dialysis.

Evidence suggesting persistence of nephritogenic immunopathologic mechanisms in patients receiving renal allografts.

Direct immunofluorescent (IF) examinations and elutions were performed on native kidneys and allografts of 24 patients undergoing renal transplantation. Immunoglobulins (Ig) were detected by IF on native kidneys of 12 of the 24; 11 of the 12 later had Ig localized to allograft glomeruli by direct IF. In addition, three other patients also developed Ig deposition on allograft glomeruli, although direct IF of native kidneys was negative. Elution studies indicated: (a) that linear Ig deposition on allograft glomeruli was the result of antiglomerular basement membrane (GBM) antibodies, (b) Ig localizing to allograft glomeruli in many of these patients was the result of persistent immunopathogenetic mechanisms existing at the time of allograft placement, and (c) occasionally, kidneys negative for Ig localization by direct IF contain elutable nephritogenic antibodies.
