Alternating Mupirocin/Gentamicin is Associated with Increased Risk of Fungal Peritonitis as Compared with Gentamicin Alone - Results of a Randomized Open-Label Controlled Trial.

Unlabelled: ♦

Background And Objectives: Catheter-related infection, namely exit-site infection (ESI) and peritonitis, is a major infectious complication and remains a main cause of technique failure for patients receiving peritoneal dialysis (PD). Topical application of antibiotic cream might reduce catheter-related infection but emergence of resistant or opportunistic organisms could be a concern. Optimal topical agents and regimens remain to be determined.

Atypical mycobacterial exit-site infection and peritonitis in peritoneal dialysis patients on prophylactic exit-site gentamicin cream.

We report 9 cases of exit-site infection and continuous ambulatory peritoneal dialysis peritonitis associated with atypical mycobacteria. All patients had been using topical gentamicin cream as prophylaxis for exit-site infection before the onset of these infections. Gentamicin cream is postulated to be a potential risk factor for atypical mycobacterial infection because of selective pressure on other micro-organisms.

Refractory thrombotic thrombocytopenic purpura and membranoproliferative glomerulonephritis successfully treated with rituximab: a case associated with hepatitis C virus infection.

Plasmapheresis remains the main treatment modality for patients with thrombotic thrombocytopenic purpura. We report a patient who had simultaneous onset of membranoproliferative glomerulonephritis and thrombotic thrombocytopenic purpura. She did not improve after 48 plasmapheresis sessions.

Efficacy of enteric-coated mycophenolate sodium in patients with active lupus nephritis.

Background: The ideal treatment of lupus nephritis has yet to be defined. Both cyclophosphamide and mycophenolate mofetil have been used with encouraging results, but adverse events are frequently seen. There are no data on the use of enteric-coated mycophenolate sodium.

Treatment of fungal peritonitis with a combination of intravenous amphotericin B and oral flucytosine, and delayed catheter replacement in continuous ambulatory peritoneal dialysis.

Background: Fungal peritonitis (FP) is associated with significant mortality and high risk of peritoneal failure. The optimum treatment for peritoneal dialysis (PD)-associated FP remains unclear. Since January 2000 we have been treating FP with a combination of intravenous amphotericin B and oral flucytosine, together with deferred catheter replacement.

Diagnosis of primary hyperoxaluria type 1 by determination of peritoneal dialysate glycolic acid using standard organic-acids analysis method.

Objective: Hyperglycolic hyperoxaluria is an important biochemical diagnostic hallmark for primary hyperoxaluria type 1 (PH1). Biochemical work-up on urinary specimens becomes impossible after the development end-stage renal failure and anuria. We studied the diagnostic value of determining glycolic acid content in peritoneal dialysate effluent in PH1.

Adverse prognostic indicators in continuous ambulatory peritoneal dialysis patients without obvious vascular or nutritional comorbidities.

Objectives: Factors that predict the occurrence of vascular events and poor patient survival in continuous ambulatory peritoneal dialysis (CAPD) patients have not been clearly defined. Previous studies have focused on nonselective CAPD patients, in whom pre-existing comorbidity or poor health might complicate interpretation of the significance of individual factors. The present study was conducted with CAPD patients without severe vascular and nutritional comorbidity.

Prevention of fungal peritonitis with nystatin prophylaxis in patients receiving CAPD.

Objective: Fungal peritonitis (FP) is a serious complication of continuous ambulatory peritoneal dialysis (CAPD), being associated with significant morbidity and mortality. The role of nystatin prophylaxis during antibiotic therapy in the prevention of FP remains controversial, especially in programs with a modest or low baseline FP rate. The aim of the present study was to evaluate the effect of nystatin prophylaxis on the occurrence of FP in programs with a relatively modest baseline FP rate.

Treatment with cyclophosphamide in elderly-onset nephrotic syndrome.

Background: The best treatment of elderly-onset nephrotic syndrome has not been well defined. The use of corticosteroids or combination immunosuppressants may be associated with a significant incidence of side effects in the elderly. There is little data on the use of cyclophosphamide alone.

Clinical presentation and outcome of severe acute respiratory syndrome in dialysis patients.

There was a major outbreak of severe acute respiratory syndrome (SARS) affecting more than 300 patients occurring in a private housing estate in Hong Kong, in which an infected renal patient was suspected to be the primary source. It is unknown whether renal patients would represent a distinct group of patients who share some characteristics that could predispose them to have higher infectivity. In this context, we have encountered 4 dialysis patients contracting SARS in a minor outbreak, which involved 11 patients and 4 health care workers, in a medical ward of a regional hospital.

Efficacy of a 1-week course of proton-pump inhibitor-based triple therapy for eradicating Helicobacter pylori in patients with and without chronic renal failure.

Background: The efficacy of short-course triple therapy for the eradication of Helicobacter pylori has been documented in patients with normal renal function. We evaluated the efficacy and safety of a 1-week proton-pump inhibitor-based triple therapy for H pylori eradication in a prospective study of patients with chronic renal failure (CRF).

Methods: Forty-two patients with a creatinine clearance (CrCl) less than 30 mL/min/1.

Tumoral calcinosis after an injection of recombinant human erythropoietin in a dialysis patient.

Tumoral calcinosis is a rare form of soft tissue calcifications, initially described as an idiopathic condition, which could occur in uremic patients. Despite its distinct clinical and morphologic presentations, the underlying pathogenesis is unknown. We present a dialysis patient who developed tumoral calcinosis over the right shoulder after receiving a misplaced injection of human recombinant erythropoietin probably into the periarticular tissue.

Long-term follow-up of thoracoscopic pleurodesis for hydrothorax complicating peritoneal dialysis.

Background: Massive hydrothorax is a significant complication of continuous ambulatory peritoneal dialysis (CAPD) and its ideal management remains undefined. Conservative management in the form of intermittent peritoneal dialysis had limited success. The use of conventional pleurodesis and open thoracotomy were associated with morbidities and limitations.
