OBJECTIVE: The objective of this study was to analyze the incidence and significance of hepatic dysfunction after cardiac surgery in children. DESIGN: Prospective, observational study. SETTING: Pediatric intensive care unit of a university hospital. PATIENTS: The study consisted of 232 children ranging in age from newborn to 17 years with no history of liver disease. MEASUREMENTS AND MAIN RESULTS: Aspartate aminotransferase (AST), alanine aminotransferase (ALT), gammaglutamyltranspeptidase (GGT), alkaline phosphatase, total and conjugated bilirubin, blood glucose, urea,
creatinine
, and coagulation studies were determined at admission, at 24 and 48 hrs, and at 7 days. Hepatic dysfunction was taken as an ALT of > 100 IU/L or a moderate or high hepatic score. The statistical study included bivariate analysis and multivariate logistic regression to study the risk factors for hepatic dysfunction. Twenty-one patients (9%) showed an ALT > 100 IU/L, and 29.3% had a moderate or high hepatic score. A relationship was found between hepatic dysfunction and the type of cardiopathy (D-transposition of the great arteries and coarctation of the aorta), shock, the administration of dopamine or epinephrine, renal insufficiency, the presence of pulmonary changes (
pulmonary edema
, atelectasis, pulmonary hypertension, hypoxemia), hematologic disturbances (prothrombin time, kaolin-cephalin time, fibrinogen, and platelets), and the need for a greater number of transfusions of packed cells, plasma, and platelets. Compared with 7.6% of the rest of the patients (p <.001), 38% of patients with an ALT > 100 IU/L died. The hepatic score of those patients who died was 4.2 (2.3)-higher than that of the survivors at 1.5 (1.8), (p <.001). Shock and renal insufficiency were the factors most significantly related to the development of hepatic dysfunction. CONCLUSIONS: Hepatic dysfunction is an uncommon complication in children after cardiac surgery. This complication is related mainly to hemodynamic disturbances and renal insufficiency and is an indicator of poor prognosis.

Acute renal failure (ARF) occasionally occurs after intravenous injection of contrast medium, but complications are rare after retrograde pyelography. After reviewing the reports in the English-language literature, the authors found very few on those complications after retrograde pyelography. The authors present a patient who had ARF after the technique. The patient had a history of hypopharyngeal cancer with underlying serum
creatinine
level at the high end of the normal limits. Bilateral flank pain and decreased urine amount were noted soon after the procedure of retrograde pyelography. Subsequently, blood urea nitrogen and
creatinine
levels both elevated, and hemodialysis was needed. Several days later, diuretic phase took place. Thereafter, the symptoms subsided gradually. Pyelorenal extravasation of contrast medium was remarkable during the procedure. There was no evidence of hydronephrosis during the course of ARF. Early awareness and management may prevent the complications of ARF such as acute
lung edema
and hyperkalemia. Therefore, clinical physicians should be aware of the occurrence of ARF and its clinical presentation after performing retrograde pyelography.

A retrospective analysis of all cases when cyclosporine (CyA) was replaced with sirolimus (SIR) to avoid the renal toxicity of CyA late after heart transplant (OHT) was discontinued due to advanced renal impairment in all five heart transplant recipients (four men, 1 women; age 41 years, range 38-45; time after OHT 5 years, range 4-14). The serum
creatinine
level at the time of SIR introduction, which was 298 micromol/L (range 217-676), had remained stable for the 6 months prior to conversion. Target SIR trough levels were 12-20 ng/mL. In four patients the last dose of CyA was immediately followed by the first dose of SIR, whereas in one patient CyA was tapered gradually in the presence of low-dose SIR. Deterioration of renal function with signs of fluid overload and increased serum
creatinine
levels (Delta: 77, 33-150 micromol/L) was observed in all patients. Two patients required dialysis during SIR treatment including one case of
pulmonary edema
requiring emergency hemodialysis. None of four biopsies showed significant rejection. Four patients were converted back to low-dose CyA (including the two patients requiring dialysis during SIR therapy); one was maintained on mycophenolate mofetil. The
creatinine
level at the time of SIR discontinuation was (range 250-753) micromol/L, 448. Eventually, all patients required dialysis. In conclusion, replacement of cyclosporine with sirolimus in heart transplant recipients with severe renal impairment late after transplantation may accelerate renal failure.

Hypoalbuminemia frequently occurs in Hemorrhagic Fever with Renal Syndrome (HFRS), but clinical significance of hypoalbuminemia is not well known. This study was designed to evaluate hypoalbuminemia as a marker of severity of disease in patients with HFRS. We evaluated the relationship between the level of serum albumin and clinical parameters representing the severity of disease in 144 patients with HFRS. The patients were divided into three groups based on the level of serum albumin; Group I (normal serum albumin), Group II (serum albumin <3.5 g/dL and >/=3.0 g/dL), and Group III (serum albumin <3.0 g/dL). Of the total of 144 patients, 42 patients (29.2%) were categorized as Group I, 39 patients (27.1%) as Group II, and 63 patients (43.8%) as Group III. Group III had a higher rate of incidence in episode of hypotension,
pulmonary edema
than did Group I and Group II. The lowest level of serum albumin was positively correlated with platelet count (r=0.505, p<0.001) and was negatively correlated with leukocyte count (r=-0.329, p<0.001), BUN (r=-0.484, p<0.001), serum
creatinine
(r=-0.394, p<0.001), and AST (r=-0.251, p=0.002). Our data suggest that hypoalbuminemia frequently occurs in the acute stage of HFRS, and level of serum albumin is associated with the disease severity of HFRS.

A 33 years old woman was admitted to the hospital after four days with cough, dyspnea, orthopnea and hemoptysis. Blood pressure was 170/90 mmHg, pulse was 112 and temperature was normal. She had cyanosis and a left ventricular gallop, without heart murmurs. A chest radiograph revealed
pulmonary edema
and echocardiogram showed a global left ventricular systolic disfunction. Oxygen and furosemide were started, but cardiopulmonary collapse ensued. The patient was supported with mechanical ventilation and treated with inotropic drugs. A right sided cardiac catheterization showed pulmonary wedge pressure of 18 mmHg and a cardiac index of 3 l/min/m2. The levels of
creatinine
and urea nitrogen were elevated and a urine protein was 97 mg/dl. Coagulation tests were normal except by a positive lupic anticoagulant. Markers of connective tissue diseases or vasculitis were negatives. The clinical evolution suggested that a catastrophic antiphospholipid syndrome was ongoing. Intravenous corticoids, gammaglobulin and cyclophosphamide were administered with transient improvement. On her fourth day of treatment, the patient presented sudden pulmonary bleeding and embolism. A plasmapheresis was performed with improvement of renal, cardiac and pulmonary function. After this episode, the patient has been treated with prednisone and oral anticoagulants treatment for the last two years, without further clinical events.

Atherosclerotic renal artery stenosis (RAS) is an increasingly important cause of end-stage kidney disease, and may cause hypertension, progressive renal failure, and recurrent
pulmonary edema
. Herein, we report two episodes of anuria and acute pulmonary edema associated with losartan treatment in a hypertensive patient with preexisting severe renal artery stenosis in a solitary kidney. After successful percutaneous renal balloon angioplasty procedure, urine flow was started immediately, despite 10 days of anuria. Blood pressure measurements were still at acceptable levels with a low dose Beta blocker, and serum
creatinine
levels were normal even after eight months. PTRA should be done in such patients, even with prolonged anuria. Physicians who recommend angiotensin receptor blockers in patients with RAS, especially in patients wih hypovolemia or a solitary kidney, should be careful about this complication.

Atherosclerotic renal artery stenosis (ARAS) may cause hypertension, progressive renal failure, and recurrent
pulmonary edema
. It typically occurs in high risk patients with coexistent vascular disease elsewhere. Most patients with ARAS are likely to die from coronary heart disease or stroke before end-stage renal failure occurs. Recent controlled trials have shown that most patients undergoing angioplasty to treat renovascular hypertension still need antihypertensive agents 6 or 12 months after the procedure. Nevertheless, the number of antihypertensive agents required to control blood pressure adequately is lower following angioplasty than for medication alone. Trials assessing the value of revascularization for preserving renal function or preventing clinical events are only in the early recruitment phase. Revascularization should be undertaken in patients with ARAS and resistant hypertension or heart failure, and probably in those with rapidly deteriorating renal function or with an increase in plasma
creatinine
levels during angiotensin-converting enzyme inhibition. With or without revascularization, medical therapy using antihypertensive, hypolipidemic and antiplatelet agents is necessary in almost all cases.

Although previous reports have attributed acute renal failure (ARF) following cardiovascular surgery to acute tubular necrosis (ATN), little emphasis has been placed on renal failure due to congestive heart failure (CARF). Of 100 cases of ARF studied prospectively over an 18-month period, 36 occurred after open-heart surgery. Nineteen of these cases were associated with heart failure. The remaining 17 had ATN as manifested by high urinary sodium, low urine/plasma
creatinine
, and abnormal urinary sediment. At the onset of CARF, intravascular volume expansion was universally present, and oliguria with
pulmonary edema
was common. Urinary chemistries were (mean +/- SD): sodium (mEq/L) 8 +/- 7, U/P
creatinine
72 +/- 45, and FENa (%) 0.1 +/- 0.1. Therapy consisted of digoxin, furosemide (F), vasopressors (V), and, when indicated, intraaortic balloon counterpulsation. Survivors of CARF responded more frequently to F and required less V. Ultimately, survival depended upon improvement in cardiac performance. All oliguric ATN patients failed to respond to F. Mortality for the CARF group was 52%. In contrast, 82% of the oliguric ATN group expired, whereas overall ATN mortality was 60%. Cardiogenic acute renal failure is a frequent cause of ARF after open-heart surgery in our institution. It is characterized by prerenal urinary chemistries, has a high mortality, and may be reversible.

We previously found that contrast-induced nephropathy (CIN) complicating percutaneous coronary intervention adversely affects patients with chronic kidney disease (CKD). Therefore, we further investigated whether the predictors and outcome of CIN after percutaneous coronary intervention differ among patients with versus without CKD. Among 7,230 consecutive patients, CIN (>or=25% or >or=0.5 mg/dl increase in preprocedure serum
creatinine
48 hours after the procedure) developed in 381 of 1,980 patients (19.2%) with baseline CKD (estimated glomerular filtration rate [eGFR] <60 ml/min/1.73 m(2)) and in 688 of 5,250 patients (13.1%) without CKD. Decreased eGFRs, periprocedural hypotension, higher contrast media volumes, lower baseline hematocrit, diabetes,
pulmonary edema
at presentation, intra-aortic balloon pump use, and ejection fraction <40% were the most significant predictors of CIN in patients with CKD. Apart from intra-aortic balloon pump use, predictors of CIN in patients without CKD were the same as mentioned, plus older age and type of contrast media. Regardless of baseline renal function, CIN correlated with longer in-hospital stay and higher rates of in-hospital complications and 1-year mortality compared with patients without CIN. By multivariate analysis, CIN was 1 of the most powerful predictors of 1-year mortality in patients with preexisting CKD (odds ratio 2.37, 95% confidence interval 1.63 to 3.44) or preserved eGFR (odds ratio 1.78; 95% confidence interval 1.22 to 2.60). Thus, regardless of the presence of CKD, baseline characteristics and periprocedural hemodynamic parameters predict CIN, and this complication is associated with worse in-hospital and 1-year outcomes.

Metabolic fingerprints, in the form of patterns of high-concentration endogenous metabolites, of 1-nitronaphthalene (NN)-induced lung toxicity have been elucidated in bronchoalveolar lavage fluid (BALF), urine, blood plasma, and intact lung and liver tissue using NMR spectroscopy-based metabolic profiling. A single dose of NN (75 mg kg(-1)) was administered orally to Sprague-Dawley rats. BALF and lung tissue were obtained 24 h after dosing from these animals and matched control rats post-mortem. High-resolution (1)H-NMR spectroscopy of BALF samples indicated that NN caused increases in concentrations of choline, amino acids (leucine, isoleucine and alanine) and lactate together with decreased concentrations of succinate, citrate, creatine,
creatinine
and glucose. In addition, the intact lung weights were higher in the NN-treated group (p<0.01), consistent with
pulmonary oedema
. The NMR-detected perturbations indicated that NN induces a perturbation in energy metabolism in both lung and liver tissue, as well as surfactant production and osmolyte levels in the lungs. As well as reporting the first NMR spectroscopic combined examination of BALF and intact lung, this study indicates that such holistic approaches to investigating mechanisms of lung toxicity may be of value in evaluating disease progression or the effects of therapeutic intervention in pulmonary conditions such as surfactant disorders or asthma.
