The 'e antigen' (eAg) is specifically associated with hepatitis B virus infections and appears to be a marker for the infectivity and a prognostic indicator of the chronicity of liver disease. Therefore we examined by immunodiffusion the presence of eAg in the seum of HBsAg-positive patients on maintenance dialysis. The dialysis patients had a significantly higher incidence of positive eAg compared with a group of unselected HBsAg-positive patients without renal failure. In most of the dialysis patients the microscopic findings in the liver revealed only 'minimal changes'. Three eAg-positive patients received a renal transplant. Afterwards they displayed an appreciably increased eAg-yield on immunodiffusion and histology revealed chronic persistent hepatitis. It is assumed therefore that the immunodeficiency of patients undergoing chronic haemodialysis is possibly a supporting factor in the synthesis of eAg, and will perhaps induce a more subscute and prolonged course of hepatitis. The synthesis of eAg after renal transplantation may be enhanced by the additional immunosuppressive therapy.

Among the diabetic patients we have treated with dialysis blood pressure and blood sugar control have been poor and vascular disease progressive. Intermittent peritoneal dialysis did not improve these problems compared with haemodialysis. Continuous ambulatory peritoneal dialysis was undertaken in three patients as a last resort and electively in another two patients. Insulin was given by the intraperitoneal route and none was used systemically. Self-care was taught from the first using the spouse if visual problems were present. Serum creatinine levels fell and haemoglobin levels rose. Blood pressure was controlled without diet or drugs. Blood sugar levels were controlled without symptomatic hypoglycaemia or rebound hyperglycaemia. The procedure had a demoralising effect on helper spouses, and self-care had to be achieved even with severe visual problems. The advantages of continuous ambulatory peritoneal dialysis to the diabetic with renal failure are greatly improved control of blood pressure and blood sugar.

Based on earlier results which indicate that certain uraemic toxins (verified by an in vitro assay system) are larger than 10,000 daltons - a new system for treatment of endstage renal failure, SElective DUal Filtration ARtificial Kidney (SEDUFARK) has been developed. This system consists of a multimembrane filter/dialyser unit making removal of small molecules (mol wt less than 200) and substances in the mol wt range 10,000 - 40,000 possible without exchange of body fluids. Evaluation of pre and post treatment uraemic plasma with the bio assay showed that SEDUFARK was superior to conventional haemofiltration (CHF) with polyacrylonitrile (PAN) or Gambro Lundia Major High Flux 1.36 m2 (CPN) membranes as filters.

Amyloid fibrils can be dissolved by dimethylsulphoxide (DMSO) in vitro and in vivo. This prompted us to investigate the therapeutic value of DMSO in renal failure caused by amyloidosis. Two patients with renal failure caused by secondary amyloidosis due to rheumatoid arthritis, showed a remarkable improvement of renal function. The effect of DMSO in amyloidosis secondary to rheumatoid arthritis seems to depend on its anti-inflammatory action, resulting in a decrease in amyloid formation. No evidence was found for an increase in amyloid degradation. The effect of DMSO in primary amyloidosis was inconclusive.

A new silastic and teflon cannula has been developed for temporary hemodialysis access. It is introduced through the subclavian vein by the Seldinger technique. The cannula which is quick and easy to insert, can be used repeatedly for weeks or months without limiting the patient's mobility and without the need for repeated vessel punctures. Complications are few and largely preventable. Since introduction of the subclavian hemodialysis cannula at the Toronto Western Hospital in September 1977 no patient with end-stage renal failure has required insertion of a silastic-teflon shunt or temporary peritoneal dialysis, nor has hemodialysis had to be postponed because of lack of an arteriovenous fistula.

The clinical course of IgA Mesangial Deposits Glomerulonephritis (MDGN) has been investigated in 178 patients for 1 to 32 years (mean 6 years) from the onset of symptoms. Impairment of renal function occurred in 28 patients, 13 of whom required RDT or died in uraemia. Hypertension was observed in 67 patients. The actuarial survival rate at ten years was 91%. A significant correlation was observed between the occurrence of renal failure and the following features: absence of episodes of gross haematuria, early appearance of hypertension, marked proteinuria and sclerosing glomerular lesions. These data suggest that IgA MDGN has generally a very prolonged course, but in a few cases may evolve, sometimes early, to chronic renal failure.

The integrity of the neurovascular reflex arc to a cold stimulus was evaluated by the determination of the response of the limb blood flow in fifteen azotemic patients. Seven of these patients became hypotensive during the course of renal failure despite comparable hemodialysis therapy. They showed a constant low blood pressure (mean blood pressure below 90 mmHg). The reactivity index (defined as the relative change at the 15th second of stimulus) was 15.9 +/- 14.4% for these hypotensive patients, and 35.7 +/- 12.0% for the remaining eight normotensive ones, while that of healthy subjects was 48.7 +/- 8.7%. The greatly diminished reactivity of the hypotensive patients could not be explained by humoral or hormonal factors. The dysfunction of somatic nerves of the vascular geometry could not be responsible for the difference. A dysfunction of adrenergic control of blood pressure was, therefore, strongly suggested.

The progressive encephalopathy observed in 5 children with chronic renal failure was clinically similar to the so-called dialysis encephalopathy of adults, except that it was not related to dialysis therapy. Renal osteodystrophy is more prevalent in children than in adults and often more severe. The attempt to control the crippling deformities of renal osteodystrophy in growing children with renal insufficiency has led to the use of large quantities of aluminum containing antacids. The encephalopathy observed in children with chronic renal failure may be related to the oral ingestion of aluminum containing compounds in the presence of persistent secondary hyperparathyroidism. We suggest that alternative methods for the adequate control of serum phosphorus levels should be sought and indications for parathyroidectomy in children reevaluated. During the past 18 mos we have lowered the dose of aluminum containing compounds to 50 to 100 mg/Kg/day in our patients with progressive renal failure and recommend parathyroidectomy. No new cases of the encephalopathy have occurred.

A cross-over study carried out over a 24 week period during 1975-76 was designed to test the relative merits of Extracorporeal versus Travenol coils for thrice weekly short periods of haemodialysis for patients with end-stage renal failure. Predictability of and capacity for ultrafiltration were excellent and equally good for both products. Leak rates in Travenol coils were 9.3% as compared to 4.3% for Extracorporeal coils. Dialysances of BUN, creatinine, and phosphate were significantly higher with Travenol coils than with Extracorporeal coils, but this increase was not as great as might be expected from the greater surface area of the Travenol coil. Despite the greater functional efficiency of the Travenol coils we could detect no difference in the degree of biochemical control of the patients as judged by standard pre and post dialysis blood chemistries. Residual blood volumes averaged 9 mls for the Travenol coils as compared to 1.6 mls for Extracorporeal coils.

In a comparison of post-dilution haemofiltration (HF) with routine haemodialysis (HD) HF was found to be technically feasible and without difficulty a method of treating end-stage renal failure patients. HF offers the theoretical benefit of a high removal rate of middle molecules at the expense of measured small molecule clearances. The reported improvement in blood pressure and hyperphosphataemia in HF could not be found in our unselected population. The better tolerance to fluid removal during HF may be due to the linear weight loss during treatment but cannot be attributed to constancy in serum osmolality HF (3 X 20-23L ultrafiltrate/week) seems to be an adequate treatment for small patients. In large, heavy patients without significant residual renal function the ultrafiltration volume has to be increased in relation to body weight. HF was found to be superior to HD in patients with fluid removal problems and frequent hypotensive episodes during HD.
