[Hemodiafiltration with endogenous reinfusion (HFR): biochemical and gas-analytical analysis of the "regenerated" ultrafiltrate].

PURPOSE: During convective techniques, a replacement fluid (R) is necessary that is sterile and pyrogen-free. Using an integrated absorption cartridge, the ultrafiltrate (UF) can be "regenerated"; and used as R. This method is hemodiafiltration with reinfusion (HFR). This study aimed to evaluate the real UF composition after "regeneration" by the resin-charcoal integrated absorption cartridge. METHODS: In eight uremic patients treated with HFR the UF was evaluated at 5, 15, 30, 60, 120, 180 and 240 min after HFR start at the inlet and the outlet resin-charcoal cartridge using the following parameters: urea, creatinine (Cr), uric acid, phosphates, glucose, Beta 2-microglobulin (beta2-m), Na+, K+, Ca++, pH, pCO2, and HCO3-. RESULTS: Blood (%): urea -61.2 +/- 9.7; Cr -55.4 +/- 8.1; uric acid -69.8 +/- 9.3; phosphates -31.8 +/- 15.7; glucose -8.4 +/- 20.5; Beta2-m -60.3 +/- 11.1; pH +0.76 +/- 0.58; pCO2+ 3.3 +/- 8.5; HCO3- +18.1 +/- 13.5. In UF (outlet vs inlet): urea was not adsorbed; Cr and uric acid were adsorbed; phosphates were not adsorbed; glucose was partially adsorbed (only in the 1st 90 min); Beta2-m was almost totally adsorbed; Na+ and K+ were not adsorbed; for pH, pCO2, and HCO3- there were no significant variations between the inlet and the outlet. CONCLUSIONS: HFR seems to be an easy-to-perform hemodiafiltration (HDF) technique, capable of resolving the typical problems of availability and the production of sterile and ultrapure reinfusion solution.

[Fabry disease].

Anderson--Fabry's disease is an hereditary disease with an X-linked genetic transmission, caused by the congenital deficiency of the lysosomial enzyme alpha-galactosidase A. It is a rare disease, but the estimated 1 patient every 117.000 male population is increasing and this can be demonstrated by simplifying the dosage techniques for the enzyme. The clinical picture comes from the accumulation of glycosphingolipids in many organs, mainly vessels, heart, nervous tissue, kidney and sight. The histological lesion appears as damage to the lysosomial membrane with subsequent migration of the lipid corpuscles into the cytoplasm and the breakdown of metabolic cellular activities. Prior to the advent of enzyme replacement therapy, which is based on the administration of the recombinant enzyme, the course of the disease was certainly fatal (early death by ictus or ischemic cardiopathy, terminal kidney failure). Despite the positive results achieved, information obtained from the present observation research should be help to verify the validity of the enzyme replacement therapy.

Sepsis-induced acute renal failure: unusual clinical presentation.

We report 4 cases of sepsis-induced acute renal failure (ARF) with peculiar clinical presentation in which the renal biopsy was the only clue to a correct diagnosis. We observed 66 cases of ARF in a 4-year experience. Seven (11%) were associated with sepsis; in 3 of these (4.5%) a shock was present. Clinical picture of the remaining 4 cases (6%) was characterized by ARF with oligoanuria and proteinuria (> 2 g/L), fever, resistant to antimicrobial therapy, negative hemocultures and severe systemic symptoms. Such a presentation could suggest a non-infectious systemic disease; renal biopsies were carried out. Histological findings consisted of microabscesses of variable size in the interstitium and within the tubular lumina. A full-dose, broad-spectrum, i.v. antimicrobial therapy was started, with favourable outcome and recovery of renal function. Our clinical experience points out that the clinical picture of ARF in course of sepsis may be variable and that its relationship with septicaemia could not be readily discernible.
