Background:Acute renal failure is a common complication of cardiac surgery, with oxidants found to play an important role in renal injury. We therefore assessed whether the supplemental antioxidant vitamin E and the inhibitor of xanthine oxidase allopurinol could prevent renal dysfunction after coronary artery bypass graft (CABG) surgery.Methods:Of 60 patients with glomerular filtration rate (GFR) < 60 mL/min scheduled to undergo CABG surgery, 30 were randomized to treatment with vitamin E and allopurinol for 3–5 days before surgery and 30 to no treatment. Serum creatinine levels and potassium and creatinine clearances were measured preoperatively and daily until day 5 after surgery.Results:The patients consisted of 31 males and 29 females, with a mean age of 63 ± 9 years. After surgery, there were no significant differences in mean serum creatinine (1.2 ± 0.33 vs 1.2 ± 0.4 mg/dL; p = 0.43) concentrations, or creatinine clearance (52 ± 12.8 vs 52 ± 12.8 mL/min; p = 0.9). The frequency of acute renal failure did not differ in treatment group compared with control (16% vs 13%; p = 0.5). Length of stay in the intensive care unit (ICU) was significantly longer in the control than in the treated group (3.9 ± 1.5 vs 2.6 ± 0.7 days; p < 0.001).Conclusion:Prophylactic treatment with vitamin E and allopurinol had no renoprotective effects in patients with pre-existing renal failure undergoing CABG surgery. Treatment with these agents, however, reduces the duration of ICU stay.
Iran, a developing country with a population of approximately 71,000,000, is the most populous country in the Middle East and the 16th most populous in the world. Gross domestic product (GDP) per capita is US$8900 and total health expenditure is approximately 6% of GDP. The total number of end-stage renal disease (ESRD) patients reported by the Management Center for Transplantation and Special Diseases (MCTSD) was 32,686 in 2007, which denotes a prevalence of 466 per million population (pmp) in Iran. Considering the growth rate of 12%, the expected number of ESRD patients in 2010 is 40,000; incidence of ESRD is expected to be 63.8 pmp. These numbers are lower compared to developed countries, which may suggest poor referral and under-diagnosis of ESRD. In Iran at present, hemodialysis (HD) and renal transplantation are the most common renal replacement therapy (RRT) modalities, accounting for 47.7% and 48.8% of prevalent RRT patients respectively. Based on the Iran Dialysis Center report of 2001, approximately 1% of ESRD patients were being treated with continuous ambulatory peritoneal dialysis (CAPD); this number increased to approximately 3.5% (6.8% of total dialysis patients) in 2006. In the present article, reasons for underutilization of peritoneal dialysis (PD) and improvements in PD within the past 5 years will be reviewed.
IntroductionCutaneous mucormycosis is a rare entity related to kidney transplantation. It usually presents with ecthyma-like lesions and black necrotic cellulitis. We report an unusual case of primary cutaneous mucormycosis presenting as erythema-nodosum-like lesions in a woman who had received a renal transplant.Case presentationA 49-year-old woman with diabetes received a living-unrelated kidney transplant. Her clinical course was uneventful for the first six months after transplantation. She then developed multiple, painful, erythema-nodosum-like lesions on her right leg and thigh following an episode of minor trauma. Mucormycosis was diagnosed by skin biopsy. Microscopic examination also showed panniculitis. The patient was treated successfully with amphotericin B and surgical resection. To our knowledge, this is the first description of primary cutaneous mucormycosis with erythema-nodosum-like lesions and panniculitis after renal transplantation.ConclusionCutaneous mucormycosis should be considered in the differential diagnosis when a kidney transplant recipient develops erythema-nodosum-like lesions with panniculitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
