Sympathetic nerve activity in renal transplant patients before and after withdrawal of cyclosporine.

Background: It has been suggested that the increase in blood pressure observed in transplant patients treated with cyclosporine is mediated by cyclosporine-induced sympathoexcitation. However, the chronic effects of cyclosporine on sympathetic outflow in renal transplant patients have not been investigated. Therefore we studied sympathetic nerve activity and blood pressure before and 6 months after the withdrawal of cyclosporine in renal transplant patients.

[Large artery wall properties -- what is relevant for the classic management of hypertension?].

Decisions about the management of patients with hypertension should not be based on the level of blood pressure alone but also on the presence of target organ damage. Apart of classical sites of target organ damage - kidney and heart - the assessment of functional and structural alterations of large arteries is of increasing clinical importance. Modern non-invasive procedures allow the assessment of large artery wall properties within the clinical routine.

Effect of pregnancy on long-term kidney function in renal transplant recipients treated with cyclosporine and with azathioprine.

In order to investigate the effect of different immunosuppressive regimens and the time interval between transplantation and pregnancy on long-term outcome, we performed a case-control study in pregnant renal allograft recipients. Eighty-one pregnancies of kidney transplanted recipients were identified [cyclosporine (CYA): n = 40; azathioprine (AZA): n = 41]. Controls were matched with respect to important prognostic factors.
