Rare occurrence of fatal Candida haemulonii peritonitis in a diabetic CAPD patient

A 68-year-old diabetic chronic kidney disease patient on continuous ambulatory peritoneal dialysis for two years developed Candida haemulonii peritonitis without any predisposing factors. There is no effective treatment for this fungus. A peritoneal biopsy showed morphological changes of acute inflammation and chronicity.     

Routine Determination of GFR in Renal Transplant Recipients by HPLC Quantification of Plasma Iohexol Concentrations and Comparison With Estimated GFR

Estimated glomerular filtration rate (eGFR) methods are not sufficiently reliable in renal transplant recipients (RTR) and should be replaced by iohexol plasma clearance measurement. However, this method has poor availability in health centers. The aim of our study was to develop a high‐performance liquid chromatography (HPLC) method for plasma iohexol measurement in routine practice and to evaluate its plasma clearance as a reference of GFR. We developed an HPLC method using UV detection. We evaluated sample storage conditions to provide recommendations for routine practice. Then, we compared GFRbased on plasma iohexol clearance (GFR‐iohexol) to eGFR using modification of diet in renal disease, Cockcroft and Gault, and CDK‐EPIequations in 40 RTR. The method was validated over a concentration range of 15–300 μg/l. Excellent linearity (r > 0.998), inter‐ and intraday precision (CV < 3.3%), and accuracy (>96.8%) were complied with ICH guidelines. We also demonstrated excellent samples stability (9 days). Although eGFR methods are not references in RTR, we found a correct concordance between eGFR and GFR‐iohexol in our population. To conclude, our method is simple, rapid, accurate, and reliable for routine clinical and research use especially in RTR. J. Clin. Lab. Anal. 26:376‐383, 2012. © 2012 Wiley Periodicals, Inc.     

Treatment of Late Class II Antibody-Mediated Rejection Status Postkidney Transplantation: Two Case Reports

We are describing the successful treatment of two cases of late Class II antibody mediated rejection status postkidney transplantation. The first patient was treated with a combination of plasmapheresis, intravenous immunoglobulin (IVIG), and stenting of the transplanted renal artery. The second was treated with IVIG and pulse steroids.     

Osmotic nephrosis with mannitol: review article

Mannitol is commonly used to lower intracranial and intraocular pressures. Large doses/massive infusions of mannitol have been found to be associated with acute renal failure (MI-ARF), that is, osmotic nephrosis. While many researchers have reported individual experiences with this pathology, we felt that there is need of an updated comprehensive review of all reported cases with elaboration of etiology, pathogenesis, diagnosis and management plan for MI-ARF. The purpose of the present communication is to share our own experience with MI-ARF, to review the effect of mannitol on kidney function and to highlight the dynamics of MI-ARF with considerations for the cautious use of mannitol in patients with risk factors for kidney diseases.     

Use of Cortisone and Antibiotics in Resistant Pelvic Infections

Although the incidence of resistant pelvic infections has been decreased, they are still a problem in spite of adequate antibiotic therapy. A new approach to such cases, in the subacute stage, is described, and the method, rationale and dangers outlined. Results obtained in the cases described, as well as in others treated subsequently, have been excellent.     

Unexpected Fabry Disease in a Renal Allograft Kidney: An Underrecognized Cause of Poor Allograft Function

Fabry disease is an X-linked recessive lysosomal storage disease caused by a deficiency of α-galactosidase A, with characteristic ultrastructural cytoplasmic myelin-like inclusions. Renal lesions are seen in male and variably in heterozygous female patients. One previous report has described Fabry disease involving a renal allograft from a deceased female donor with no history of Fabry disease. The authors describe another case, in which suspicion for Fabry disease was raised ultrastructurally. This serves as a reminder that proteinuria after renal transplantation may be due to donor-derived disease. Fabry disease is probably an underrecognized cause of graft dysfunction. This case provides further justification for ultrastructural examination of renal allograft biopsies.     

Torsemide Versus Furosemide After Continuous Renal Replacement Therapy Due to Acute Renal Failure in Cardiac Surgery Patients

Acute renal failure (ARF) usually develops in 5% to 30% of patients undergoing heart surgery and is associated with a more complicated clinical evolution course and with an excessive mortality of up to 80%. The objective of this study was to verify the frequency of ARF in postoperative coronary artery bypass surgery with and without cardiopulmonary bypass, by the evaluation of renal function markers' performance [ plasma creatinine, plasma urea, urinalysis, fractional excretion of sodium, creatinine clearance and Alpha‐glutathione S‐transferase (α‐GST)], besides to verify possible relations between clinical variables involved in postoperative heart surgery and the occurrence of renal insufficiency.
