Acute renal failure after thrombotic agent therapy due to excessive bleeding after cosmetic liposuction

Suction lipoplasty is practiced popularly for obesity control and cosmetic purposes and severe complications are rare. We report the first documented case of acute renal failure, with anuric period, that developed after excessive bleeding following cosmetic liposuction. The use of homocoagulase and the presence of rhabdomyolysis might have contributed to the acute renal failure and disseminated intravascular coagulation observed in this case.     

Acute renal failure after nonmyeloablative hematopoietic cell transplantation

Acute renal failure (ARF) is a common life-threatening complication after myeloablative allogeneic hematopoietic cell transplantation (HCT). Nonmyeloablative HCT aims to eradicate the malignancy with graft-versus-tumor effect, rather than with high doses of chemoradiotherapy. It may be anticipated that a lower risk of ARF exists in nonmyeloablative HCT as a result of the milder preconditioning regimen. However, the patients who receive the nonmyeloablative HCT are older individuals who are not eligible for the more toxic allogeneic myeloablative procedure. The goal of this study was to evaluate ARF in a large group of patients who received nonmyeloablative HCT. This cohort study enrolled patients who were undergoing nonmyeloablative HCT at four major centers from 1998 to 2001. Conditioning therapy involved total body irradiation 2 Gy +/- fludarabine 30 mg/m2. Posttransplantation immunosuppression consisted of cyclosporine or tacrolimus and mycophenolate mofetil. ARF was classified into four grades, similar to previous studies in the literature. Collectively, 253 patients were recruited into this study. ARF (>50% decrease in GFR) occurred in 40.4% of patients over a 3-mo period, with 4.4% of patients requiring dialysis. The overall mortality in the study population was 34% at 1 yr. The mortality increased with worsening grade of ARF. The combined need for dialysis and artificial ventilation was associated with a mortality exceeding 80%. Although the number of patients who develop ARF is significant, the risk of developing ARF that requires dialysis after nonmyeloablative HCT is infrequent despite the older age of the patients. The data are also suggestive that ARF may contribute to mortality after nonmyeloablative HCT.     

Acute hyperuricemic nephropathy and renal failure after transplantation

This report describes a patient who was treated for rejection of a cadaveric renal allograft with a variety of drugs, including the continuous administration of ciclosporin over a period of 16 months. The patient developed hyperuricemia, attacks of gout and finally a rapidly progressing renal failure 17 months after transplantation. The removed transplanted kidney showed extensive tubular dilatation, intratubular deposits of uric acid crystals and characteristic granulomas. There was also morphologic evidence of transplant glomerulopathy, as well as scattered linear parenchymal (cortical?) scars of the type seen in mild chronic ciclosporin toxicity. Both of these changes undoubtedly contributed to the reduction of renal reserve. However, we propose that prolonged continuous use of ciclosporin was the main factor in the development of hyperuricemia and obstructive hyperuricemic nephropathy and renal failure in this patient. To our knowledge cases of this nature have not been previously reported.     

Acute intratubular obstructive renal failure after ampicillin treatment

Sir, Hospital acquired renal insufficiency has been increasing infrequency in recent years and now accounts for 7.2% of patientsadmitted to the hospital for renal failure [1]. Its most commoncause is a decrease in renal perfusion. Medications (mainlyantibiotics) that variously produce nephrotoxicity also frequentlycause renal failure during hospitalization [1]. We present apatient with Listeria monocytogenes meningitis treated withhigh     

Acute renal failure after cadaveric related liver transplantation

Acute renal failure (ARF) is a frequent medical complication after liver transplantation (LT). We analyzed cadaveric related liver transplant recipients who had developed ARF early in the postoperative course. Between January 1982 and August 2003, a total of 67 patients underwent cadaveric related LT. Their mean age was 28.64 years at LT. The 67 recipients had the following indications: biliary atresia (n = 17), Wilson's disease (n = 15), hepatitis B-related liver cirrhosis (n = 14), hepatitis C-related liver cirrhosis (n = 4), primary biliary cirrhosis (n = 4), hepatitis B-related liver cirrhosis with hepatoma (n = 3), hepatitis C-related liver cirrhosis with hepatoma (n = 2), Budd-Chiari syndrome (n = 2), neonatal hepatitis (n = 1), choledochus cyst (n = 1), autoimmune cirrhosis (n = 1), neuroendocrine tumor (n = 1), and hemangioendothelioma (n = 1). Forty-nine patients received cyclosporine (CsA), azathioprine, and steroids and 18, a combination with tacrolimus (FK506). Eight (11.94%) patients developed ARF at a mean time of 17.25 days after LT. The mean peak serum creatinine was 2.24 mg%. Four of these patients had a diagnosis of hepatitis B-related liver cirrhosis; two, hepatitis C-related liver cirrhosis; one, primary biliary cirrhosis; and one, hepatitis B-related liver cirrhosis with hepatoma. The ARF etiology was multifactorial for the majority of patients. Eight ARF patients had a history of liver cirrhosis, which may be a risk factor for intraoperative ARF. ARF treatment included fluid replacement, decreased or altered immunosuppressive agents, avoiding exposure to nephrotoxic drugs, and adjusting antibiotic dosages. The majority of patients returned to normal renal function at 1 to 3 weeks after the diagnosis of ARF. No patient required dialysis and/or experienced a mortality. We conclude that the incidence of ARF is relatively low and with good outcomes. ARF etiology was multifactorial for the majority of patients, but eight patients had a history of liver cirrhosis, which may be a risk factor for intraoperative ARF. We suggest that in the early postoperative period of LT cases diagnosis and treatment of ARF are important.     

Acute renal failure after total hip replacement.

Eight of forty-one patients undergoing total hip replacement experienced acute but not fatal renal failure postoperatively. All forty-one patients received transfusions of frozen blood and albumin and their wounds were irrigated with a bacitracin-neomycin-polymyxin solution. All subsequently had some relative hypotension. None of a second, prospective group of fifty-five patients who received the transfusion of albumin, but not frozen blood or the bacitracin-neomycin-polymyxin irrigant, had renal failure. The incidence of hypotension in this group was comparable to that in the first group, yet no cases of renal failure were seen. We therefore recommend that the combination of frozen blood and potentially nephrotoxic drugs be avoided in patients undergoing total hip replacement.     

Acute renal failure requiring renal replacement therapy after orthotopic liver transplantation

OBJECTIVES: Acute renal failure (ARF) is a severe complication in patients undergoing orthotopic liver transplantation (OLT), which predicts a poor outcome. The aim of this study was to analyze risk factors for the development of ARF, including severity of illness, onset time of ARF prognostic factors of outcome, and mortality in a group of critically patients requiring renal replacement therapy (RRT). METHODS: Retrospective analysis of 240 consecutive liver transplant cases from 1999 to 2001 admitted to the intensive care unit (ICU) was performed to identify risk factors for ARF development after OLT. The analyzed factors were: age, sex, CrS, BUN, diuresis, sepsis, hypovolemia, cardiac failure, nephrotoxic drugs (cyclosporine or FK506, antibiotics), hyperbilirubinemia, associated diseases (DM, CRF), onset time of renal failure and progressiveness, timing of RRT, number of days of RRT, and mortality. We examined variables upon admission to the ICU, before the first RRT, and on the last ICU day before resignation or death. We used Students' t test. Quantitative parameters were expressed as mean values +/- SD. RESULTS: Of the 240 patients, 20 (8.3%) experienced ARF needing renal replacement therapy during the postoperative period. The results of our study suggested that ARF among patients undergoing RRT conferred an excessive risk of in-hospital death: eight patients died (40%). This increased risk cannot be explained solely by a more pronounced severity of illness. CONCLUSION: Our results provide strong evidence that ARF presents a specific, independent risk factor for a poor prognosis.     

Acute renal failure after exercise in a patient with renal hypouricemia

A 22-year-old man had recurrent exercise-induced acute renal failure (ARF). He was found to have isolated renal hypouricemia: serum uric acid level was 0.7–1.0 mg/dl and fractional excretion of uric acid (FE_UA) was 37%–43%. He showed no suppression of FE_UA following the the administration of pyrazinamide, and no increase of FE_UA after benzbromarone, suggesting a subtotal defect. We investigated renal function, FE_UA, and serum nitric oxide after a treadmill exercise test in our patient and two control subjects. On the day after the exercise test, plain and enhanced abdominal computed tomography (CT) scans were performed in our patient. During the arterial phase, early equilibration phase, equilibration phase, and 2, 6, and 24 h after the injection of contrast medium, renal CT scans were performed at the same slice level. Although ARF was not induced by this level of exercise, the CT scans showed patchy contrast enhancement 2, 6, and 24 h after contrast medium administration. This finding suggests that patchy renal vasoconstriction may occur in patients with renal hypouricemia after strenuous exercise, even in the setting of normal creatinine clearance.
