Background: Self-regulation theory explains how patients' illness perceptions influence self-management behaviour (e.g. via adherence to treatment).

Patients returning to haemodialysis or peritoneal dialysis after a failed kidney transplantation sometimes have a renal allograft left in situ for some urine production. Low-dose immunosuppressive medication is often continued in such patients. To evaluate the morbidity and mortality between patients in time periods with (group A) or without (group B) low-dose maintenance immunosuppression, the present study was initiated.

Objective: Since renal sympathetic nerves are involved in the regulation of sodium excretion, we investigated whether treatment with urapidil, an alpha1-adrenoceptor blocking agent which also lowers sympathetic activity, alters sodium excretory capacity in patients with essential hypertension.

Design: A double-blind, randomized, parallel-group study.

Methods: Studies were carried out in 26 patients who were randomized to treatment with either placebo or urapidil for 8 weeks.

Aims: The aim of this study was to determine the potential influence of renal impairment on the pharmacokinetics of temocapril and its pharmacologically active diacid metabolite, temocaprilat.

Methods: Non-compartmental pharmacokinetics were assessed in four groups of hypertensive patients (n=8 per group, four investigational centres) with normal (creatinine clearance determined via 24 h urine sampling, CL[CR], > or = 60 ml min-1) and impaired renal function (CL[CR] 40-59, 20-39, < 20 ml min-1) after 14 once daily oral doses of 10 mg temocapril hydrochloride.

Results: For temocapril, there were no statistically significant differences in median tmax or mean Cmax, AUC(SS), t1/2,Z, CL/F between the four groups.

This study investigated whether the acute natriuretic effect of nitrendipine is related to its initial renal hemodynamic effects. We investigated 16 patients (10 men and 6 women, mean age 52 +/- 2 years) with essential hypertension, whose treatment, if any, was stopped 3 weeks before the study. They were admitted to a metabolic ward for 9 days and kept on a constant sodium diet of 55 mmol/day.
