A 46-yr-old female with chronic pyelonephritis was found to lack complement (C) activity by the use of hemolytic screen assays in agarose gels. These assays also revealed a propensity of patient serum to form an activated complex of the fifth and sixth components of C, C56. Each of the C component hemolytic activities was present in normal or elevated amounts with the exception of C7, which was undetectable; addition of purified C7 led to the restoration of hemolytic activity. C-dependent phagocytosis, immune adherence, and neutrophil chemotaxis were normal. Family studies demonstrated that the defect was transmitted as an autosomal codominant apparently not linked with alleles at the HLA-A or HLA-B loci. Persisting C56 was readily formed in this as compared to normal serum upon incubation with multiple C activators including zymosan, inulin, immune complexes, heat-aggregated human gamma globulin, endotoxin, and agarose. A heat-stable (56 degrees C, 30 min) activity which consumed C7 with time-and temperature-dependent kinetics was detected in plasma and serum, and seemed to be similar to a "C7 inactivator" previously described in another C7-deficient individual. However, this activity was found to have properties identical to those of C56 during low ionic strength precipitation and chromatography on Sephadex G-200, to be specifically removed upon passage through an anti-C5 immunoadsorbent column, and to be associated with a small amount of C56, suggesting that it represents an expression of small amounts of C56 rather than a new C-inhibitory activity. Thus, an individual with chronic nephritis lacking C7 is reported; the utility of a hemolytic screen assay in agarose plates for the detection of such patients is emphasized; persisting C56 is shown readily to be formed in this serum; and the presence of C7-consuming activity which is associated with and in all likelihood attributable to C56 is shown.

Glomerulonephritis patients transplanted with cadaver kidneys had a significantly higher one-year graft survival when immunosuppressed with cyclosporin rather than standard therapy (80% versus 59%, p less than 10(-5]. For nephrosclerosis patients the corresponding rates were 70% and 59% (p greater than 0.05); and in those with antecedent diabetes mellitus, polycystic kidney, and pyelonephritis the differences were negligible. In glomerulonephritis patients, but not in the other groups, cyclosporin was additive to the effect of transfusions and of HLA-A, B and HLA-Dr matching.

The study of the current status of renal replacement therapy in Japan is based on the analysis of data from the registry reports for regular dialysis therapy and kidney transplantation. The total number of patients receiving regular dialysis therapy was 123,926 at the end of 1992: 117,809 (95.1%) on hemodialysis and 6,117 (4.9%) on peritoneal dialysis. The primary diseases of newly accepted patients were chronic glomerulonephritis (42.2%), diabetic nephropathy (28.4%), nephrosclerosis (5.9%), polycystic kidney disease (2.7%), chronic pyelonephritis (1.6%), and others. The number of kidney transplant patients in Japan was 8,384 at the end of 1991: 6,154 (73.4%) received a living donor transplantation and 2,230 (26.9%) received a cadaver donor transplantation. Overall 5-year survival rates of dialysis patients were 60.4%: 69.7% for chronic glomerulonephritis, 41.7% for diabetic nephropathy, 39.6% for nephrosclerosis, 73.6% for diffuse polycystic kidney disease, and 66.6% for chronic pyelonephritis. The causes of death of dialysis patients were heart failure (31.1%), cerebrovascular accident (13.6%), infectious diseases (11.3%), malignancies (7.1%), cachexia/uremia (6.7%), myocardial infarction (5.8%), and others. The gross mortality rate of dialysis patients was increased in cases of less than 4 hours of the average length of each dialysis session, less than 4% and more than 9% of the average weight loss during each dialysis session, less than 1.0 of Kt/V, and less than 0.9 and more than 1.7 g/kg/d of protein catabolic rate. Overall 5-year patient and graft survival rates of kidney transplant patients since 1964 were 82.7% and 60.3%: 84.4% and 65.0% in living donor cases, and 77.4% and 46.2% in cadaver donor case, respectively. Those since 1983 were 90.1% and 68.2%: 91.3% and 72.6% in living donor cases, and 87.8% and 59.3%, respectively. Graft survival rates were superior in cases treated with combined steroid, cyclosporine and azathioprine or mizoribine, to those treated with other immuno-suppressive regimens, and they decreased as the number of HLA-A, -B and -DR increased.
