Low-dosage ibopamine treatment in progressive renal failure: a long-term multicentre trial.

A multicentre trial (11 nephrology centres) was carried out to test the effects of ibopamine, an orally active dopamine-like drug, on the progression of chronic renal failure. For a 2-year period 189 chronic renal failure patients (serum creatinine level 1.5-4.

[Echo-Doppler in chronic kidney transplant rejection. The diagnostic prospects using indices of the ascending systolic phase].

To date, Doppler US has been rarely used to diagnose chronic renal transplant rejection because of its low sensitivity. Nevertheless, all the results have been obtained from the analysis of flow-metric indices, mainly considering the diastolic phase of the Doppler waveform, e.g.

[Doppler echography and color Doppler echography in the assessment of the vascular functional aspects of medical nephropathies].

This study was aimed at finding a Doppler parameter to distinguish, among medical nephropathies, the ones with glomerular from those with vascular or tubulointerstitial involvement. Therefore, 32 patients (20 men and 10 women, average age: 43 years, range: 10-77 years) with clinical and laboratory signs of medical renal disease were examined with color-Doppler US. The resistive index (RI, n.

Behavior of beta 2-microglobulin (B2-m) serum levels in uremic patients.

This study was performed in 97 hemodialysis patients (85 on HD and 12 on CAPD) to investigate the possible correlation between B2-m and hemodialysis-related amyloidosis syndromes (HRA-S); differences in B2-m and HRA behavior between patients hemodialysed with cellulose and synthetic membranes were also included in the present study. Data indicate that B2-m levels are not correlated with dialysis length or with the type of membrane used for the dialysis. On the contrary, in 16 patients with the Carpal Tunnel Syndrome, a significant correlation was found between the CTS, the dialysis length and the type of membrane (greater incidence with cellulosic membranes).
