    Notes: Summary Four patients with primary hyperaldosteronism were treated with nadroparin 4100 or 6150 antiXa IU daily for 4 days. Plasma and urine sodium and potassium, and plasma aldosterone and renin were monitored before, during and after the study. After four days of treatment, and for the following two days, plasma aldosterone was decreased (by a mean of 49% on Day 6), and urinary Na/K was increased (3.7-fold). The direction of the changes was reversed on Day 8. The study has confirmed the effect of low molecular weight heparin on aldosterone, and makes it unlikely that it is related to inhibition of angiotensin II stimulation in these patients, as renin could not be detected in their plasma.

    Notes: Summary Chronic hyperglycaemia results in glycation of serum albumin and might affect the binding of drugs. The aim of the present study was to compare, using an equilibrium dialysis method, the protein binding of therapeutic concentrations digitoxin, valproate and phenytoin in sera from 70 insulin-dependent diabetics and 25 controls. Drug concentrations were measured by fluorescence immunopolarisation. Glycated albumin was measured by laser nephelometry after affinity chromatography. In sera from diabetics, protein binding of digitoxin (88.8 versus 89.9%) was unchanged; the protein binding of valproate (75.2 versus 80.7%) and phenytoin (67.9 versus 75.3%) was significantly decreased, but with no correlation with the concentration of glycated albumin. We conclude that the difference in protein binding between diabetic and control sera is due to glucose-independent modification of albumin in diabetics.
