Late recovery of renal function in a woman with the hemolytic uremic syndrome.

A case is reported of the hemolytic uremic syndrome (HUS) in a woman taking oral contraceptives. She was treated with heparin, dipyridamole and hemodialysis; and after more than three months, her urinary output rose above 500 ml; and six months after the onset of anuria, dialysis treatment was stopped. This case emphasizes the possibility that HUS in adults is not invariably irreversible and that, despite prolonged oliguria, recovery of renal function can be obtained. Therefore, in adult patients affected by HUS, dialysis should not be discontinued prematurely; moreover, bilateral nephrectomy, for treatment of severe hypertension and microangiopathic hemolytic anemia, should be performed with caution.

Pharmacokinetics and effects of propranolol in terminal uraemic patients and in patients undergoing regular dialysis treatment.

Propranolol blood and plasma levels were measured after a single oral dose of 40 mg in patients with chronic renal failure, in patients undergoing regular dialysis treatment, and in healthy volunteers. Peak levels were observed in all cases within 1.5 to 3 hours. However, peak blood and plasma concentrations of propranolol in the chronic renal failure group were 2- to 3-fold higher (161 +/- 41 ng/ml) than those observed in the dialysis patients (47 +/- 9 ng/ml) and in the healthy volunteers (26 +/- 1 ng/ml). The apparent plasma clearance was also significantly reduced in the patients with chronic renal failure. The data suggest a reduced hepatic extraction in chronic renal failure patients. A significant increase in the fraction of the dose available to the systemic circulation was also found, together with a modification of apparent plasma half-life and volume of distribution in regular dialysis patients during the dialysis day as compared with the after-dialysis day. No extraction of propranolol by the dialyzer was noticed. Marked fluctuations in propranolol blood concentrations were also observed in patients on regular dialysis following continuous propranolol treatment. The suppressive effect of propranolol on plasma renin activity did not fully correlate with the hypotensive effect of the drug. On the basis of the reported data, propranolol should be used with great caution and at low doses in chronic renal failure.

Lipid patterns in haemodialysed and transplanted patients.

The plasma lipid pattern was investigated in 103 dialysis patients and 66 renal transplant patients. Only 32 percent of dialysed patients and 30 percent of transplanted patients had a normal lipid pattern. In other patients the most frequent disorder with hypertriglyceridaemia, and less frequently combined or isolated hypercholesterolaemia. Since these lipid abnormalities are known to predispose to an accelerated atherosclerosis, a dietetic therapeutic approach was tried. Fifteen transplanted patients with severe hypertriglyceridaemia were submitted to a hypocaloric (1700 kcal) and low carbohydrate (130 g) diet. During dieting the plasma lipid pattern was normalised and maintained in a normal range for the period of observation (3-12 months).

Reversible acute anuric lupus nephritis.

Six cases of acute anuric lupus nephritis are described; renal biopsy showed intracapillary proliferation, epithelial crescents in some glomeruli, wire loops, and intracapillary thrombi. In two patients there were thrombotic occlusions and fibrinoid necrosis of arterioles. The patients were treated by heparin at anticoagulant doses, corticosteroids and dialysis (four). All patients showed improvement of renal function. One died following a gastric haemorrhage - the others were alive and well 64, 61, 40, 40 and 22 months from the onset of renal failure. One patient had a second episode of acute renal failure after 39 months and improved after resumption of heparin and high doses of steroids. It is suggested that heparin and high doses of corticosteroids may be a successful treatment in acute anuric lupus nephritis.

Acute renal failure in systemic lupus erythematosus.

Acute anuric renal failure complicating systemic lupus erythematosus does not usually respond to treatment with corticosteroids and immunosuppressive agents. We describe four cases treated by dialysis, corticosteroids, and heparin in anticoagulant doses in which there was remarkable improvement in renal function after prolonged anuria. One patient died later from a gastric haemorrhage. The other three were alive and well 55, 54, and 30 months from the onset of anuria. In two cases a second renal biopsy showed a striking improvement in the lesions. Large doses of corticosteroid and heparin may be the best treatment in acute anuric lupus nephritis.
