Low incidence of hyperparathyroidism in diabetic renal failure.

The first study compared two groups on dialysis: 25 patients with diabetes mellitus and 25 matched non-diabetic patients, in relation to the presence of signs of hyperparathyroidism, to assess the reported low incidence of hyperparathyroidism in these patients. The diabetic group showed significantly lower values of PTH, Alk phosphatase, percentage of patients requiring vitamin D treatment, and less evidence of hyperparathyroidism on X-ray and in bone histomorphometry. In the second study 16 patients with chronic renal failure due to diabetic nephropathy were compared to 27 patients with the same degree of renal failure of other origin, the diabetic nephropathy group showed no increase in PTH, with falling creatinine clearance. Despite this low PTH, the phosphaturia was higher in the diabetic nephropathy group (Tm PO4/C Cr: 1.94 +/- 0.43 vs 2.5 +/- 0.68). In conclusion, patients with diabetes mellitus are less prone to develop hyperparathyroidism in progressive renal failure. This could be due to a relative increase in phosphaturia during declining function.

Sequential intraperitoneal administration of nitroprusside in patients maintained on peritoneal dialysis.

Clinical studies were made in order to determine the effects of intraperitoneal nitroprusside on the peritoneal clearances according to different frequencies of drug administration. An important increase of urea and creatinine clearances with 3.75 mg of nitroprusside per liter of dialysis solution was observed. The maximum effects were observed after four consecutive exchanges with the drug; its effects were maintained all through the peritoneal dialysis session and in some cases increased when alternative series of four exchanges with and without drug were carried on. The significative higher increase of the big solutes clearances suggests a vasodilator action of nitroprusside which should be also reflected on an increase of the middle size molecules clearances. Clinical tolerance was excellent and the blood pressure variations were negligible.
