摘要:

Prediction of outcome of acute renal failure (ARF), particularly inpatients with multisystem organ failure (MSOF), is a very important issue and a very difficult task. In patients with ARF as a consequence of severe polytrauma, frequent complications (e.g., sepsis, respiratory insufficiency, DIC, hepatic insufficiency, etc.) contribute to a hyperbolic state, and in the case of synergistic action, they start the mechanism of MSOF. In 33 patients (1 female, 32 male, 38.61±8.79 years) with severe polytrauma acquired in war combat, ARF developed requiring hemodialysis (HD) treatment. Seventeen out of 33 (51.4%) recovered renal function. In 12 out of 33 patients, MSOF occurred with less successful recovery results. The analysis of pathophysiologic mechanisms of MSOF appearance and ARF outcome has shown the importance of blast injuries, bowel injury, respiratory insufficiency requiring assisted ventilation, and sepsis. Although severe hemorrhage and shock are the common mechanism of ARF appearance in these patients, it seems that wounds by themselves can be of great importance, as abdominal wounds are more frequently associated with ARF and MSOF than in other types.

摘要:

During a 36-month period from 1992 to 1994, 33 patients with severe polytrauma acquired in war combat (1 female, 32 male, 38.61±8.79 years) developed acute renal failure (ARF) which required hemodialysis (HD) treatment. In 12 patients, multiple system organ failure (MSOF) occurred as a complication of either general conditions or septic complications. In 17 patients (51.4%), and in 3 patients with MSOF, recovery of renal function occurred. We compared the outcome of ARF and several predictive scores (APACHE II and ATNISS). The APACHE II score did not correlate with the outcome of ARF, and ATNISS significantly correlated with the outcome of ARF. The maximum value of ATNISS in the patients with lethal outcome was 1.004, and the minimal value with the same outcome was 0.182. Although ATNISS is a very good score of severity, it seems to underestimate very influential factors in patients with severe polytrauma with ARF (MSOF, mechanism of trauma).

摘要:

The records of 563 patients admitted to the hospital with diagnosis of acute pancreatitis have been studied retrospectively. The aim of the study was to investigate the prevalence of acute renal failure (ARF) in these patients, and to evaluate the most important risk factors for ARF development and mortality. The prevalence of ARF in studied population was 14%, but only 3.8% of ARF patients with acute pancreatitis had isolated renal failure. Other patients had additional failure of other organ systems, 68.4% of whom had multiorgan failure (MOF) before the onset of ARF. In only 8.9% of ARF patients was the renal system the first organ system to fail. Patients with ARF were significantly older, had more preexisting chronic diseases (including chronic renal failure), usually had MOF, and local pancreatic complications relative to these in the group with normal renal function. The development of ARF was directly influenced by severity of acute pancreatitis. The mortality rate in ARF patients was 74.7%, compared to an 7.4% mortality of patients with acute pancreatitis and normal renal function. Preexisting chronic disease, the presence of MOF and their number, local pancreatic complications, and older age of the patients increased mortality in ARF patients. The prognosis of patients with oliguric ARF requiring renal replacement therapy was extremely poor, indicating the importance of prevention of ARF in the patients with acute pancreatitis.

摘要:

To assess the prevalence of acute renal failure (ARF) inpatients with acute pancreatitis, as well as the factors predictive of a lethal outcome, we retrospectively studied the data of all patients admitted to our hospital over a 5-year period. Between 1989 and 1993, 554 patients presented with acute pancreatitis, of which 24 (4.4%) subsequently developed ARF. Death occurred in 14/24 (58%) of patients with ARF, and was associated with an increased incidence of multiorgan failure. There was no statistically significant difference in the age, admission blood pressure, or admission pulse rate of the patients who survived and those who died. In contrast, death was associated with a higher Ranson score, and the increased prevalence of multiorgan failure. The length of hospitalization of the nonsurviving group was significantly shorter. Acute renal failure is not a common finding in patients with acute pancreatitis. However, when it occurs, it is associated with a poor prognosis, and is predicted by a higher Ranson score and the presence of multiorgan failure.

摘要:

The aim of our study was to analyze the clinical course and outcome of acute renal failure (ARF) in patients with hemorrhagic fever with renal syndrome (HFRS). From 1983 to 1995, we treated 33 patients (27 males, 6females) aged from 16 to 71 years. Half of patients were connected with work at a farm or in a forest. The disease was confirmed serologically with indirect immunofluorescence test (IFT) and enzyme-linked immunosorbent assay (ELISA). In 18 patients percutaneous kidney needle biopsies were analyzed. In 85% of the cases, the disease broke out from June to October. The most frequently expressed clinical signs and symptoms were fever, nausea/vomiting, headache, backache, abdominal pain, myalgia, diarrhea, conjunctival injection, and hemorrhages. Four patients had concomitant pancreatitis. In 25 patients, oliguria was present, and transient hemodialysis treatment was needed in 19 patients. Infection with Hantaan virus was established in 20 patients and with Puumala virus in 13 patients. At renal biopsy, acute interstitial nephritis accompanied with hemorrhages and necrosis was found, and at a later biopsy there were also signs of interstitial fibrosis. All patients were cured, but renal function was not completely recovered in some. We conclude that ARF is a serious complication in patients with HFRS. Although not lethal in our group of patients, many of them showed severe signs and symptoms of illness. Transient hemodialysis was necessary in two-thirds of the patients. Some degree of functional defects and morphological changes might persist.

摘要:

Previous studies have reported a 4%-50% incidence of acute renal failure (ARF) following the use of radiocontrast media in patients with preexisting chronic renal insufficiency. In these studies, ARF was defined as a rise of the serum creatinine of at least 1 mg/dl above baseline. Using the same criteria, we studied 214 patients undergoing various intravascular radiocontrast media procedures. Patients were infused with a specially prepared cocktail solution (NSMF) containing 1000 ml half-normal saline, 12.5 g of mannitol (M), 1 ampule NaHCO3, and 200 mg offurosemide (F) at 100 ml/h from one hour prior to two hours after the procedure. Urinary output was replaced with normal saline for at least 6 h after the procedure. Seven percent of the patients developed acute renal insufficiency. Only 3% of the patients had a rise in serum creatinine greater than 2 mg/dl. No patient required dialysis therapy after the procedure. There was one unrelated death caused by acute myocardial infarction postangioplasty. Risk factors for development of ARF despite cocktail administration included the presence of diabetes mellitus and angiotensin converting enzyme (ACE) inhibitor therapy. We concluded that the properly administered NSMF solution protects against radiocontrast dye induced renal failure. In select patients with chronic renal insufficiency, consideration should be given to withholding ACE inhibitor therapy for 24-48 h prior to administration of intravenous radiocontrast dye. A large controlled trial will be required to establish whether the NSMF solution offers benefit beyond that of saline hydration alone.

摘要:

The aim of this study is to evaluate the effects of contrast media on both tubular and glomerular function. Different parameters of tubular and glomerular function were determined before and at 1, 3, and 5 days after the intravascular administration of contrast media in 100 adult renal patients (plasma creatinine 0.6-10.8 mg/dL, mean: 1.3). Urinary activities of five tubular enzymes (alanine aminopeptidase,γ-glutamyltransferase, alkaline phosphatase, lactate dehydrogenase, N-acetyl-β-D-glucosaminidase) increased significantly on the first day after the administration of contrast media, indicating a tubular damage. Glomerular filtration rate and the conventional tests of glomerular function (plasma creatinine, creatinine clearance, and urinary proteins) presented only slight variations after the administration of contrast media. In conclusion, contrast media principally affected the renal tubule (as demonstrated by enzymuria), while their effects on glomerular function were very mild.

摘要:

The aim of this study is to evaluate the nephrotoxicity of two contrast media (CM), with different physicochemical characteristics: diatrizoate (ionic high-osmolar), iopromide (nonionic low-osmolar). Intravenous urography was performed in 34 patients: 17 were examined with diatrizoate and 17 with iopromide, randomly assigned. Different parameters of glomerular and tubular function were measured before and at 6, 24, and 48 h after urography. Both contrast media induced a reversible increase of urine enzymes, which was significantly higher after diatrizoate. In particular, diatrizoate determined a relevant increase of brush border enzymes -γ-glutamyltransferase (GGT) and alkaline phosphatase (ALP) and of cytosolic enzyme lactate dehydrogenase (LDH), while, after iopromide increases of urinary enzymes were less evident and were significant only for GGT and ALP. In addition, diatrizoate affected other tubular functions (clearances of phosphorus and uric acid) and slightly decreased glomerular function in a few patients. In no case did these glomerular and tubular effects have a clinical relevance. In conclusion, the nonionic low-osmolar contrast medium iopromide appeared less nephrotoxic than diatrizoate. The cost-benefit ratio needs further examination.

摘要:

The objective of this study was to compare the evolution of patients with acute renal failure (ARF) treated conservatively or with different dialytic techniques in an intensive care unit (ICU). From June 1992 to November 1994, 1087 consecutive patients were admitted in our ICU. Two hundred and twenty of these presented with ARF, and were divided into three groups: group I (control group): 156 patients with ARF who did not receive substitutive techniques; group II: 21 patients under intermittent hemodialysis (IHD) or peritoneal dialysis (PD); group III: 43 patients under continuous hemodiafiltration (CHDF). The studied variables were age, etiology of renal failure, requirement of dialysis, type of dialysis, length of ICU and hospital stay, and renal function outcome. APACHE II and SAPS scores were recorded on admission and analyzed for hospital mortality. Chi-square test and the analysis of variance were used for the statistical analysis. Results are presented as mean±SD. A p value below 0.05 was considered statistically significant. Although etiology of ARF was multifactorial, we found a high frequency of ARF due to sepsis (56.8%), hypoperfusion (58.7%), and acute tubular necrosis (62.5%). Sepsis and heart failure were clinical conditions associated to a greater mortality. We did not find any statistical difference between the two dialyzed groups for all the studied variables, nor between the three groups regarding APACHE II and hospital stay. Significant differences were found between dialyzed and non-dialyzedpatients respect to age, group I: 64.1±13.6, group II: 56.4±19.7, and group III: 56.0±14.1 fp<0.001), creatinine peak serum levels, group I: 260±130, group II: 494±209, and group III: 441±170μmol/L (p<0.0001), and mortality, group 1:46.9%, group II: 66.7%, and group III: 76.2% (p<0.002). SAPS score showed differences between the control group and the CHDF group 13.9±4.8 and 16.4±5.4 (p<0.007), respectively. The use of dialytic techniques in critically ill ARF patients is associated with greater mortality. Prognostic indexes on admission did not correctly classify our patients with ARF. Continuous hemodiafiltration does not involve greater mortality or length of stay as compared to conventional dialysis.

摘要:

Between 1990 and 1993, we studied 14 cases of acute renal failure due to prolonged muscular exercise (e.g., squat jumping, sit-ups) and blunt trauma inflicted by law enforcement personnel using sticks or leather belts. None of the patients had a prior history of myopathy, neuropathy, or renal disease. All were critically ill and required renal support in the form of dialysis. Although the morbidity was high, 13 of the patients recovered normal renal function. One patient expired due to sepsis.
