An outbreak of dialysis dementia due to aluminum in the dialysate.

The dialysis dementia syndrome was observed in eight of 21 patients dialyzed in a small center during a 22-month period in which dialysate contained aluminum levels of 618 microgram/liter. This incidence of 38% was significantly higher than the zero incidence of four prior years when no aluminum was added to city water (p less than 0.05) and also when compared to the zero incidence in the 2.5 years subsequent to deionization of dialysis water which lowered its aluminum content to less than 1 microgram/liter (p less than 0.0002). Since other factors were not altered, we conclude that aluminum intoxication from the dialysate was the cause for the outbreak of this progressive encephalopathy.

Progressive dialysis encephalopathy from dialysate aluminum.

Progressive dialysis encephalopathy was observed as a frequent complication (eight of 34 patients) in a small hemodialysis unit. After the water used for dialysis was deionized, no further cases of encephalopathy developed in 29 patients. In the absence of other apparent changes in therapy, this significant difference in incidence (P less than .005) is considered to be the result of reduction in unusually high water aluminum levels from 0.637 mg/liter to less than 0.001 mg/liter by use of a deionizer.

Pneumonia in recipients of renal allografts.

Pneumonia developed in 33 of 266 renal transplant recipients while they were receiving immunosuppressive therapy. Clinical factors were compared for patients with pneumonia and the control group of 220 transplant recipients without pneumonia. The diagnosis was usually established roentgenographically. Most cases of pneumonia were of bacterial origin and occurred within three months after transplantation. Pneumonia occurring during the first two postoperative weeks had no fatal outcomes. Patients with pneumonia occurring three to 12 weeks after transplantation had significantly greater leukopenia (P less than .05) and more therapy for allograft rejection (P less than .01) than the control group. Cases of fungal pneumonia developed later, were preceded by rejection, and had a poor prognosis. The mortality was 51.5% for all cases of pneumonia. Early diagnosis, prompt administration of specific antimicrobial agents, and immediate cessation of immunosuppressive therapy should improve the survival rate.

Evaluation of acetate tolerance during highly efficient hemodialysis.

Acetate clearance was found to approximate bicarbonate clearance and to be 10% lower than urea clearance under single pass in vitro conditions. Plasms acetate concentrations were significanlty higher in pre-dialysis samples than in control subjects and rose during hemodialysis to a wide range of post-dialysis levels. In 17% of patients plasma acetate exceeded 9.5 mM/L and range to 21.6 mM/L. The cause for this apparent acetate intolerance is probably multifactorial, since severe hyperacetatemia is not a constant finding for any specific patient. Correction of pre-dialysis acidosis may be impaired by acetate accumulation.
