Subclavian vein stenosis as a complication of subclavian catheterization for hemodialysis.

Thirteen patients had placement of a subclavian vein catheter for temporary vascular access for hemodialysis. Peripheral venography was performed within two to six weeks of catheter placement. Forty-six percent (six of 13 patients) developed subclavian vein narrowing, which resolved in two patients. The duration of catheter placement had no impact on the incidence of this complication. Subclavian vein catheterization can frequently lead to subclavian vein stenosis, which often will resolve spontaneously. Consideration should be given to placement of subclavian lines on the contralateral side of a planned permanent vascular access.

Comparison of eosinophilia in patients undergoing peritoneal dialysis and hemodialysis.

Eosinophilia (E) has been noted in hemodialysis (HD) patients, but its etiology is not clear. In an effort to clarify this phenomenon, we prospectively studied patients initiating dialysis in our outpatient HD and peritoneal dialysis programs. Rate of E was greatest for a small group of four continuous cycling peritoneal dialysis patients (75%), less for 63 HD patients (41%), and least for 66 continuous ambulatory peritoneal dialysis (CAPD) patients (21%, P less than .05, HD v CAPD). Increasing E rates among the groups paralleled increased frequency of tubing changes. There were no differences in etiology of renal disease, medications, types of dialyzers, types of access, or transfusion frequency that could account for the E. IgE levels did not correlate with E. The data suggest that the dialysis procedure or the tubing changes may be causing the E, but the possibility that uremia, itself, is important in the pathogenesis of dialysis E is also discussed.

Nondilated obstructive nephropathy.

Three patients had renal failure due to obstructive nephropathy associated with processes that prevented dilatation of the collecting systems. Thus, various radiologic procedures, including renal sonography, angiography, and isotope renography, all failed to identify an obstructing process. Because of the high index of clinical suspicion, surgical exploration and nephrostomy were performed on each patient. This confirmed the presence of obstructive nephropathy and led to marked improvement of renal function in each case. When renal failure develops in a setting with a high probability of ureteral obstruction, this diagnosis should be vigorously pursued despite normal radiologic results.

Continuous ambulatory peritoneal dialysis: establishment and growth of a program in a large metropolitan area.

We describe our experience at the Booth Memorial Medical Center with the development and growth of a Continuous Ambulatory Peritoneal Dialysis program. This initial experience includes the training and close follow-up of 41 patients with End Stage Renal Disease over a period of 15 months. The status of our program with respect to medical complications encountered and their management is described. Our results, in terms of biochemical control, success with training, and patient satisfaction with CAPD are outlined.

Eosinophilic peritonitis.

The development of cloudy peritoneal dialysis effluent is of great concern to the patient undergoing therapy with Continuous Ambulatory Peritoneal Dialysis. As described in this study, not all cloudy fluid represents bacterial infection. We describe the occurrence of cloudy fluid in eight patients in whom culture of the dialysate did not yield any growth, and whose cell count was characterized by the presence of significant numbers of the eosinophiles. As outlined, the entity of eosinophilic peritonitis has a characteristic presentation which allows for its distinction from the more common bacterial peritonitis.

Amyloidosis secondary to drug abuse and chronic skin suppuration.

Amyloidosis has not been included in the wide spectrum of medical complications associated with drug abuse. Chronic visceral infection is a recognized cause of amyloidosis, but chronic suppuration of the skin is not a well-appreciated cause of this condition. Furthermore, to our knowledge, chronic skin suppuration secondary to parenteral drug abuse has not been reported as a cause for systemic amyloidosis. We report a case in which subcutaneous injections of narcotic tablets led to chronic skin suppuration and systemic amyloidosis.

Lactic acidosis in diabetic patients.

Plasma lactate and beta-hydroxybutyrate concentrations were measured during episodes of ketoacidosis and lactic acidosis in diabetics. In 39 patients with ketoacidosis, with a mean plasma beta-hydroxybutyrate concentration of 12.4 millimols/liter, the plasma lactate concentration was less than 3.6 millimols/liter in 28 and moderately elevated in 11. In seven of the latter, coexisting lactic acidosis had been suspected clinically. In these 39 patients, there was no correlation between plasma lactate and beta-hydroxybutyrate concentrations. In six of ten episodes of presumed and later proved lactic acidosis, despite negative or weakly positive serum reactions with sodium nitroprusside, the plasma beta-hydroxybutyrate concentration was elevated. Although positive, the serum reaction with nitroprusside was also misleadingly weak in five of 39 patients with ketoacidosis, including three with plasma lactate concentrations less than 3 millimols/liter.
