Median Serum Creatinine (median + serum_creatinine)
Selected AbstractsPlasmapheresis as rescue therapy in accelerated acute humoral rejection,JOURNAL OF CLINICAL APHERESIS, Issue 3 2003Kottarathil A. Abraham Abstract Accelerated acute humoral rejection (AHR) continues to occur in renal transplantation despite improved crossmatching, with potentially devastating consequences. Between 1 June 1998 and 31 December 2000, 440 renal transplants were performed in our center. AHR was diagnosed by the demonstration of typical pathological features on renal histology and positive direct immunofluorescence or detection of anti-HLA antibodies in serum. AHR developed in 20 (4.5%) of our renal transplant recipients, nine male and eleven female at an average of 16.3 days post transplantation. All of these patients had a negative current cytotoxic crossmatch prior to transplantation. The median serum creatinine at diagnosis was 5.96 mg/dL, and 83% of these individuals developed oliguric renal failure requiring dialysis after having initially attained good graft function (median of best serum creatinine before AHR was 2.64 mg/dL). The 18 recipients who had not infarcted their grafts at the time of diagnosis of AHR received plasmapheresis in conjunction with intensification of their immunosuppressive regimen. This regimen was successful in reversing AHR in 78% of those treated with apheresis. In the 14 responders, graft survival at 6 months was 100% and at 12 months was 91%. Median serum creatinine at 6 and 12 months was 1.26 and 1.33 mg/dL, respectively. Patients received an average of 8.1 plasma exchanges. However, responders received a significantly higher frequency of plasmapheresis (P = .0053), despite undergoing a similar number of exchanges overall. Plasmapheresis appears to be an effective modality for reversing AHR and maintaining graft function. J. Clin. Apheresis 18:103,110, 2003. © 2003 Wiley-Liss, Inc.

All patients received steroids with or without azathioprine. At 12 months, 85% of CsA-ME patients and 86% of tacrolimus patients survived with a functioning graft (P not significant). Efficacy was similar in deceased- and living-donor recipients. Significantly fewer hepatitis C,positive patients died or lost their graft by 12 months with CsA-ME (5/88, 6%) than with tacrolimus (14/85, 16%) (P < 0.03). Recurrence of hepatitis C virus in liver grafts was similar in each group. Based on biopsies driven by clinical events, the mean time to histological diagnosis of hepatitis C virus recurrence was significantly longer with CsA-ME (100 ± 50 days) than with tacrolimus (70 ± 40 days) (P < 0.05). Median serum creatinine at 12 months was 106 ,mol/L with CsA-ME and with tacrolimus. More patients who were nondiabetic at baseline received antihyperglycemic therapy in the tacrolimus group at 12 months (13% vs. 5%, P < 0.01). Of patients who were diabetic at baseline, more tacrolimus-treated individuals required anti-diabetic treatment at 12 months (70% vs. 49%, P = 0.02). Treatment for de novo or preexisting hypertension or hyperlipidemia was similar in both groups. In conclusion, the efficacy of CsA-ME monitored by blood concentration at 2 hours postdose and tacrolimus in liver transplant patients is equivalent to 12 months, and renal function is similar. More patients required antidiabetic therapy with tacrolimus regardless of diabetic status at baseline. Liver Transpl 12:1464,1472, 2006. © 2006 AASLD. [source] Experiences with acute kidney injury complicating non-fulminant hepatitis ANEPHROLOGY, Issue 6 2008HYUN W KIM SUMMARY: Aim: To describe the clinical features and to identify factors related to development of acute kidney injury in acute hepatitis A patients. Methods: The study and control groups consisted of 21 and 425 patients who did or did not develop acute kidney injury, respectively, after acute hepatitis A from January 1997 to May 2007. Results: There were 13 men and eight women; their mean age at diagnosis was 28.8 ± 8.2 years in the study group. Peak values for renal and liver function impairment consisted of a median serum creatinine of 4.6 mg/dL (range, 1.5,15.3 mg/dL) on day 6 (range, days 1,20) and a median total bilirubin of 10.7 mg/dL (range, 2.6,57.5 mg/dL) on day 8 (range, day 1,19). Serum creatinine concentrations returned to baseline level by a median of 16 days and total bilirubin levels returned to normal by a median of 62 days. Six of 21 (29%) patient underwent haemodialysis. Renal biopsies performed in two patients showed acute tubular necrosis and interstitial nephritis, respectively. Logistic regression analysis showed that a lower haematocrit, the presence of coagulopathy and high C-reactive protein concentration on admission, and higher peak bilirubin value during the illness were associated with development of acute kidney injury. Conclusion: Acute hepatitis A should be considered in the differential diagnosis of patients with acute kidney injury, even without fulminant hepatic failure. A lower haematocrit, the presence of coagulopathy and high C-reactive protein level at presentation, and higher peak bilirubin level during the illness were associated with development of acute kidney injury in acute hepatitis A patients. [source] The Outcome of Patients with Nephrogenic Systemic Fibrosis after Successful Kidney TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2010N. Leung Nephrogenic systemic fibrosis (NSF) is a debilitating disease in patients with severely diminished kidney function. Currently, no standard treatment exists but improvement has been reported after restoration of kidney function. We retrospectively studied 17 NSF patients with and without successful kidney transplantation (KTx) to evaluate the effects of KTx on NSF. Nine of the 11 KTx developed NSF pretransplant whereas two developed NSF immediately after KTx with delayed graft function. Two of the six dialysis patients had previous failed kidney transplants. Age and sex were well matched. All but one patient was dialysis dependent at the time of NSF. Median follow-up was 35 months for KTx patients and 9 months for dialysis patients. Kidney transplants achieved adequate renal function with median serum creatinine of 1.4 (0.9,2.8) mg/dL and a glomerular filtration rate of 42 (19,60) mL/min/1.73 m2. NSF improved in 54.6% of the transplanted patients and 50% of the nontransplanted patients (p = 0.86). Two KTx patients had complete resolution of their symptoms whereas four had partial improvement. Improvement in the dialysis patients was all partial. Successful KTx did not insure improvement in NSF and in fact appeared to have no significant benefit over dialysis. [source] | ||||||||||
