[Survival of patients starting dialysis at an advanced age in the Piedmont].

BACKGROUND: Patients starting dialysis in old age (age > 70 and > 80) in Piedmont are widely increasing: the survival curves of this group of patients can give very important information to evaluate the quality of both the delivered therapy and our very wide criteria of acceptance to the treatment. To this end, using data from the Piedmont Dialysis and Transplant Register, the survival curves of patients with age over 70 and 80, beginning dialysis in all Piedmont Dialysis Units between 1981 and 1996, have been examined. METHODS: These curves have been considered both in a general way and according to the presence or absence of further high risk conditions; they show results better than expected and improving from 1981 to 1995. RESULTS: If the survival curves of these patients are considered according to the kind of dialytic treatment performed, they do not show any significative difference. CONCLUSIONS: The conclusion is drawn that these data strongly support first, the fitness of criteria of very wide acceptance to the treatment and modulated choice of the kind of dialytic treatment at present followed in Piedmont; and second, that dialysis treatment can give very good results also in elderly patients. So, it is suggested that the economic and structural difficulties of dialysis Units must not influence the nephrologist's choice towards elderly patients.

[The complement system in kidney diseases].

The multifaceted relations between complement system and immune-mediated nephropathies are reviewed. Several conditions in which either the complement activation induces renal damage without hypocomplementemia or hypocomplementemia occurs in the absence of circulating IC are reported as well as disorders in which immune complexes promote hypocomplementemia. The complement system is involved in the clearance of immune complexes, both modifying the immune complex size and favouring the physiologic neutralization by the erythrocyte transport system. In certain pathological conditions the immune complex intrinsic characteristic or genetic abnormalities prevent efficient removal from the blood stream. The purpose of the present review is to summarize these conditions, briefly describing their pathological consequences, and indicate a simple scheme to correctly interpret the biochemical abnormalities of the complement system in nephropathology.

Indium-111-labeled granulocyte head accumulation in patients with Wegener's granulomatosis.

Among the symptoms of systemic vasculitis, purulent rhinorrhea with painful sinusitis is thought to be relatively specific to Wegener's granulomatosis (WG). Sixteen patients with rapidly progressive glomerulonephritis (GN), arteritis and extensive crescents in renal biopsy were studied by head indium-111 (111In)-granulocyte scanning. They included 8 WG, 5 microscopic polyarteritis, 2 necrotizing and crescentic GN and 1 classic polyarteritis nodosa. Autologous granulocytes labeled with 12.3 MBq of 111In-oxine were administered intravenously. Scintigraphic studies were performed at 4 and 24 h post-injection. Compared to the non-WG cases, considered as a whole, significant accumulation of tracer in sinuses was observed in WG patients (Fisher's p = 0.02). Substantial scintigraphic amelioration was obtained in a WG case treated with methylprednisolone pulses and, in another WG case, after high doses of intravenous gamma-globulins. The complete disappearance of facial uptake was obtained after 2 months of intensive therapy (i.e., steroid, cyclophosphamide and plasma exchange) in another WG patient. 111In-oxine granulocyte imaging may be useful in clinical practice as an additional marker of disease activity and a tool of identification of upper respiratory tract involvement.
