Paecilomyces peritonitis: case report and review of the literature.

While filamentous fungi are a rare cause of peritonitis in peritoneal dialysis patients, there is increasing recognition of Paecilomyces species as pathogens in such patients. We herein report a case of fungal peritonitis secondary to the filamentous Paecilomyces variotii species. The patient had a long and ultimately fatal course of illness despite catheter removal, discontinuation of peritoneal dialysis, recurrent intraabdominal abscess drainage, and prolonged courses of antifungal therapy. Our experience with this case and a review of the literature suggests that infection with this fungus can cause substantial morbidity and is probably best treated with prompt catheter removal, aggressive antifungal therapy and vigilant observation for complications.

Obstruction to venous outflow from the left lower extremity after renal transplantation.

Three patients with acute massive swelling of the left lower extremity occurring soon after placement of a renal allograft in the left iliac fossa are described. In each patient, obstruction to venous outflow from the left lower limb was documented by venography. We surmise that venous obstruction resulted principally from a combination of extrinsic compression of the left iliac vein by the right common iliac artery or by the allograft, and enhanced venous return from the allograft.

Demonstration of Fabry's disease deposits in placenta.

Involvement of the placenta by glycosphingolipid deposits in Fabry's disease has not been previously reported. We describe the presence of such deposits in the maternal half of a placenta obtained from a heterozygous carrier of the disease.

Asymptomatic, nonketotic, severe hyperglycemia with hyponatremia.

We describe five patients with asymptomatic, nonketotic, severe hyperglycemia (serum glucose concentrations between 45.8 and 92 mmol/L) in the face of renal insufficiency are described. As opposed to most of the previously described patients with hyperglycemic, nonketotic, hyperosmolar coma, our patients were hyponatremic. The lack of symptoms in our patients may be related to the absence of cerebral cellular dehydration. Aggressive treatment of hyperglycemia in such patients is unnecessary. Attention to the serum sodium level as well as to the serum glucose concentration will allow recognition of this clinical entity.

Predicting need for surgical drainage of pericardial effusion in patients with end-stage renal disease.

The best approach to treatment of pericarditis accompanied by substantial pericardial effusion in end-stage renal disease (ESRD) patients is unknown. In a review of our experience, we found that ESRD patients with moderate-to-large or large (circa 250 mL or larger) pericardial effusions usually failed to improve with intensive dialysis and ultimately required surgical drainage of the effusion. Multivariate analysis revealed that effusion size was by far the most important factor predicting need for surgery. Since early pericardial drainage obviates the risk of sudden tamponade, we recommend that surgery without prior intensive dialysis therapy be considered in such patients.

Induction of peritoneal fluid eosinophilia and/or monocytosis by intraperitoneal air injection.

We hypothesized that intraperitoneal air might be one of the causes of peritoneal fluid eosinophilia. To test our hypothesis, we injected 100-500 ml of sterile air intraperitoneally into 5 patients receiving continuous ambulatory peritoneal dialysis (CAPD). All patients responded with a transient increase in peritoneal fluid nonerythrocyte cell count (peak counts ranging from 23 to 335 cells/mm3, mean peak count 140 +/- 125) lasting 4 days (after injection of 100 ml of air) to 7 weeks (after injection of 500 ml of air). In 2 patients, the cells were predominantly monocytes (80 +/- 6.5%), whereas in 3 patients, eosinophils predominated (63 +/- 12%), while monocytes (30 +/- 19%) also increased. Resolution of peritoneal fluid pleocytosis correlated temporally with absorption of subdiaphragmatic air. Our results suggest that intraperitoneal introduction of air into CAPD patients can induce peritoneal fluid eosinophilia and/or monocytosis.

Involvement of renal allograft by Fabry's disease.

A man with Fabry's disease received a renal allograft from a heterozygous sister. Renal allograft dysfunction necessitated an allograft biopsy 5.5 years after transplantation. Extensive accumulation of Fabry's disease deposits in the glomeruli, tubules, blood vessels and interstitium was noted.

Heparin-associated thrombocytopenia in maintenance hemodialysis patients.

Thrombocytopenia associated with the presence of a heparin-dependent platelet aggregating factor developed in two patients after hemodialysis with heparin. It resolved in one patient after heparin was stopped; but persisted in the other during a two-week heparin-free period and intermittently thereafter. We suggest that when heparin causes thrombocytopenia in dialysis patients the heparin should be stopped whenever possible, but this may not be necessary in all patients.

Transdermal clonidine in mild hypertension. A randomized, double-blind, placebo-controlled trial.

In 30 patients with mild essential hypertension, clonidine hydrochloride was delivered from a skin patch reservoir designed to release medication at a constant rate for seven days. After a four-week washout period, patients were randomized (double-blind) into a clonidine- or a placebo-treated group. Clonidine or placebo was then given for five weeks, followed by a two-week washout period to assess withdrawal from treatment. Blood pressure was controlled in 11 of 15 clonidine-treated patients but in only four of 15 placebo-treated patients. The clonidine-treated group evidenced larger decreases in both systolic and diastolic blood pressures. In the clonidine-treated group, blood pressures and plasma clonidine levels were stable throughout a representative seven-day period. Besides mild skin irritation with both clonidine and placebo patches, few side effects were observed. After discontinuation of clonidine administration, plasma levels declined in a non-log linear manner. There was no rebound hypertension. The results suggest that clonidine delivered transdermally is safe and effective for control of mild essential hypertension.

Subxiphoid pericardiostomy for hemodialysis-associated pericardial effusion.

Sixteen patients receiving maintenance hemodialysis in whom moderate-to-large pericardial effusions developed were treated with short-term drainage via a large-bore tube implanted into the pericardial sac. Drainage tubes were implanted using a subxiphoid approach (subxiphoid pericardiostomy) while the patient was under local anesthesia. In seven patients, triamcinolone hexacetonide was instilled into the pericardial sac through the drainage tube at regular intervals. In all patients, a drainage period of two to four days, with or without instillation of nonabsorbable steroids, was associated with resolution of the pericardial effusion. Only one recurrence of effusion was demonstrable over a follow-up period extending from three months to eight years (median, 4.2 years). Complications of subxiphoid pericardiostomy were minor (incisional hernia, wound infection, and small pneumothorax) and easily treatable. Our results suggest that short-term drainage via a surgically implanted drainage tube is an effective and safe treatment of moderate-to-large hemodialysis-associated pericardial effusion.

Pyocystis in a renal transplant recipient with a defunctionalized bladder.

Fever occurred in a man 6 weeks after renal transplantation. At the time of transplantation, the donor ureter had been anastomosed to a ureteroileal conduit created 6 years previously because of traumatic neurogenic bladder. Initial evaluation failed to reveal the cause of the fever, but ultimately, drainage of the defunctionalized bladder yielded a large amount of pus infected with Klebsiella pneumoniae. Our patient's course suggests that, when fever develops after renal transplantation in patients with previous urinary diversion, pyocystis should be included in the differential diagnosis.

Severe anaphylactoid reactions to cuprammonium cellulose hemodialyzers.

Twenty-one severe reactions to hemodialysis occurred in approximately 260,000 dialysis treatments at three centers within a 10 1/2-year period. Reactions typically appeared within minutes of initiating dialysis, and were characterized by cardiopulmonary, mucocutaneous, and/or gastrointestinal tract symptoms highly suggestive of anaphylaxis. Four respiratory arrests and one death resulted. Analysis of dialyzer use patterns and of each patient's dialyzer exposure history strongly implicated hollow-fiber dialyzers made of cuprammonium cellulose (CC) as a cause of these reactions. No obvious factors could be found to identify predisposed patients. Less than optimal rinsing of the CC hollow-fiber dialyzers prior to use may have been responsible for some, but not all, of these reactions.
