[Statistical analyses on over ten years survivals in Hokkaido under chronic dialysis therapy].
In Hokkaido, there were 305 chronic dialysis patients surviving more than ten years as of July 31, 1985. All patients except for one (CAPD) have been placed under hemodialysis. About 73% of them were introduced into a dialysis therapy in their thirties and chronic glomerulonephritis was extremely predominant as for the underlying disease. 93.2% of the cases possessed internal AV-fistulae using own vessels and other types of blood access remained only 6.8%. Hematocrit (Hct) was 27.5% on average of 305 cases. The value was fairly satisfactory but it must be noted that Hct of 33 patients (10.8% of all) was less than 20%. Severe anemia is still one of major complication in chronic dialysis patients. Characteristic complications, which have been increasing in frequency in parallel with prolonged dialysis length, became clarified: renal osteodystrophy, secondary hyperparathyroidism, carpal tunnel syndrome, persistent hypotension and so on. The former two are strongly related to Ca & P metabolism and some of the long-term survivals require parathyroidectomy. It is now estimated that carpal tunnel syndrome is induced by accumulation and deposition of beta 2-microglobulin, which increases in blood progressively if used Cuprophane membrane dialyser. Patients with CTS must be placed under surgical intervention, which relieves the symptoms effectively and the prophylaxis might require protein-permeating dialyser.
