The arthropathy of maintenance intermittent peritoneal dialysis.

Among 61 patients undergoing maintenance peritoneal dialysis for an average of 20 months, 13 (21%) had a history of attacks of acute arthritis and 19 (31%) were found to have tender and often swollen joints. Deposits of calcium pyrophosphate dihydrate crystals in articular cartilage were identified in four patients and inflammation probably induced by hydroxyapatite crystals was noted in one. Periarticular calcification was observed in 12 patients and subperiosteal resorption of the phalanges in 20. The average calcium X phosphorus product was significantly higher (P < 0.025) in patients with a history of attacks of acute arthritis or with inflamed joints (58 +/- 12) than in those without (50 +/- 12). In the 19 patients whose treatment was changed to continuous ambulatory peritoneal dialysis there was a significant decrease (P < 0.025) in the calcium X phosphorus product but not in the proportion of patients with attacks of acute arthritis or with inflamed joints. The results indicate that articular complications are frequent among patients undergoing maintenance peritoneal dialysis and may be more common than with long-term hemodialysis.

Reappraisal of protein losses in patients undergoing continuous ambulatory peritoneal dialysis.

Dialysate effluent protein content was measured in 22 patients undergoing continuous ambulatory peritoneal dialysis (9 with and 13 without previous peritonitis). The average amount of protein in those patients without peritonitis was 1.3 g/2 liters exchanged over a 6-hour period, while that of patients with previous peritonitis was 2.6 g/2 liters exchanged over the same period. 71% of protein found in the dialysate of 2 patients was albumin. Despite the difference in the amount of protein lost between those without and those with peritonitis, there was no significant difference in their mean serum albumin levels (3.2 and 3.4 g%, respectively) which were only slightly below the normal range. The previously reported high protein losses in patients undergoing CAPD are probably the result of frequent episodes of peritonitis and a higher number (five) of daily exchanges.

The evolution of renal osteodystrophy in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).

Since the introduction of continuous ambulatory peritoneal dialysis by Popovich et al [1] and the subsequent modification of the technique by Oreopoulos et al [2], an increasing number of patients with end-stage renal disease are maintained on this new treatment modality. To date, there has not been any report of the effect of CAPD on the evolution of renal osteodystrophy which is one of the major complications of chronic renal failure. In this report we will present the results of our radiological and biochemical studies of renal osteodystrophy in 28 patients who have been on CAPD from 6 to 23 months.
