Kidney transplantation in type 1 (insulin-dependent) diabetic patients. Early glomerulopathy.

The development of diabetic glomerulopathy in kidneys transplanted to diabetic patients was estimated in transplant biopsies and evaluated in relation to suspected clinical risk factors for diabetic nephropathy. Surgical biopsies were taken at baseline and at 24-36 months post-transplantation in 16 Type 1 (insulin-dependent) diabetic patients and 8 non-diabetic control subjects with a glomerular filtration rate more than 30 ml.min-1 at follow-up. Immunosuppressive therapy included cyclosporine in all but one case. Stereological methods were used to assess basement membrane thickness, volume fraction of mesangium per glomerulus, and volume fraction of matrix per mesangium. The volume fraction of interstitial tissue per cortex was estimated by light microscopy. After 2 years the basement membrane thickness had increased by 55 nm (SD 58 nm) in the diabetic group. This change was significantly different from that of 2 nm (SD 37 nm) in control subjects (p = 0.02). Mesangial volume fraction increased significantly by 0.04 (SD 0.03) in diabetic patients, and this change was significantly different from that of -0.01 (SD 0.04) in non-diabetic patients (p = 0.009). No change was detectable in the matrix expressed as fraction of mesangial volume. An increase in interstitial volume fraction from baseline to 2 years was observed, but was significant only in the diabetic group (p = 0.04). The changes in structural parameters did not correlate with mean values during follow-up of glycated haemoglobin or estimated protein intake, nor was any pattern discernible in the relationship to graft tissue types.(ABSTRACT TRUNCATED AT 250 WORDS)

Outcome of pancreas transplantations in Göteborg, Sweden 1985-1990.

During 1985 to 1990, 67 segmental pancreas transplantations with bladder drainage were performed. Fifty were combined pancreas and kidney and 17 were pancreas after kidney transplants. All patients were transplanted with the same technique. The 1-year actuarial pancreas graft survival for the combined patients with quadruple immunosuppressive therapy was 83% and the patient survival, 95%. The most important complications were infections, leakage from the pancreatico cystostoma and vascular complications.

Adult type of polycystic kidney disease in a new-born child.

A case of polycystic kidney disease in a newborn child is reported. Renal cortical necrosis due to asphyxia was the cause of death. The histopathological picture and a heavy family history support the rare diagnosis of polycystic kidney disease of adult type in a new-born child.
