Vasoactive hormones in uraemic patients with chronic hypotension.
The results indicate that in HD patients with chronic hypotension there is an activation of the sympathetic and the renin-angiotensin systems, probably secondary in an attempt to compensate the vascular resistance to pressor stimuli reported in these patients.
Long-term evolution of patients with isolated C3 mesangial glomerulonephritis.
After 7 years of follow-up, renal function was declining in 4 of 5 patients who developed terminal renal failure up to requiring hemodialysis, therefore, initial benign prognosis ascribed to this glomerulonephritis would not be confirmed in a long-term follow- up.
Fibrillary glomerulonephritis and pulmonary hemorrhage in a patient with renal transplantation.
The presence of fibrillo-reticulary deposits in the interstitium, similar to those observed in the glomeruli, indicates the possibility of systemic involvement in fibrillary glomerulonephritis.
Autonomic nervous system and adrenergic receptors in chronic hypotensive haemodialysis patients.
Normotensive haemodialysed patients have increased plasma catecholamine levels with preserved alpha 2- and beta 2-adrenoceptor numbers, as well as beta 1- and 1-adRenoceptor responses, and this downregulation may play a role in the reduced cardiovascular responses to adrenergic stimuli reported in hypotensive HD patients.
