Since it has been recognized as a separate disease during the Korean war, hemorrhagic fever with renal syndrome (HFRS) has often been discovered among the members of different armies in various countries, military personnel being the highest risk group for the disease. In the period from March to May 1999 we treated 6 soldiers coming from the military formation stationed at Kosovo and Metohia. The reaction of indirect hemagglutination test proved the presence of antibodies against Hantavira in each of them. They were infected during the stay in a dugout in the area with great population of field rodents. Only one patient was slightly ill, on the admission to the hospital. The others had severe clinical and laboratory findings: several days lasting fever, strong abdominal pain, as well as the pain in the loins, dyspeptical discomfort, manifold increased blood urea nitrogen and serum creatinine values, thrombocytopenia, etc. Oliguria occurred in 4 patients. Hemorrhagic manifestations were slight (epistaxis, petechial rash, conjunctival injection), or absent. Because of the aggravation of the acute renal failure, hemodialysis was performed in 3 patients, while other 3 underwent conservative treatment. Two of the patients had severe anemia because of which transfusions of erythrocytes and plasma were performed. Complications occurred in 2 patients (convulsive crises and lung infections). All patients recovered completely.

Acute renal failure is a common occurrence in sepsis, but is rarely reported in meningococcemia. We present a young child diagnosed with fulminant meningococcemia who had several poor prognostic factors, including hypotension, thrombocytopenia, purpura fulminans, seizures, the absence of meningitis with meningococcemia, and acute renal failure, which was successfully treated with peritoneal dialysis. Peritoneal dialysis was started on the 5th day because the patient had been anuric for 48 h. At that time, analysis showed that the child was both hypokalemic and hypophosphatemic. His serum blood urea nitrogen was 61 mg/dl, creatinine 2.75 mg/dl, potassium 2.8 mEq/l, and phosphorus 0.7 mg/dl. Urine output began on the 12th day post admission and normalization of serum creatinine was achieved on the 26th day. In conclusion, renal failure is an important complication of meningococcemia and, to be effective, sometimes long-term peritoneal dialysis is required. Profound metabolic abnormalities, such as hypokalemia and hypophosphatemia, may occur paradoxically in the presence of oliguria.

A 64-year-old man was admitted to our hospital because of general fatigue and drowsiness. On admission, a physical examination disclosed dehydration and a laboratory investigation revealed the following values: plasma glucose, 1309 mg/dl; serum sodium, 160 mmol/l; potassium, 3.0 mmol/l; urea nitrogen, 65 mg/dl; creatinine, 2.73 mg/dl; and plasma osmolarity, 403 mOsm/kg. Urine ketone bodies were negative. A diagnosis of hyperosmolar non-ketotic diabetic syndrome was made, and hydration with an infusion of hypotonic saline (0.45%) and insulin therapy were immediately started. However, despite adequate rehydration and correction of blood glucose, his serum creatinine level increased to 3.1 mg/dl, while oliguria and myoglobinuria developed on the 4th hospital day, with serum creatine kinase increasing up to a maximum level of 16,749 IU/l, suggesting rhabdomyolysis. A final diagnosis of hyperosmolar non-ketotic diabetic syndrome associated with rhabdomyolysis and acute renal failure was made. His renal function gradually improved without hemodialysis, though acute renal failure due to rhabdomyolysis with hyperosmolar non-ketotic diabetic syndrome can sometimes be fatal. This rare case is presented along with a review of literature.

Acute renal failure (ARF) is a common problem in the neonatal intensive care unit (NICU). In most cases, ARF is associated with a primary condition such as sepsis, metabolic diseases, perinatal asphyxia and/or prematurity. This retrospective study investigated the course of illness, therapeutic interventions, early prognosis and risk factors associated with development of ARF in the neonatal period. A total of 1311 neonates were treated in our NICU during the 42-month study period, and 45 of these babies had ARF. This condition was defined as serum creatinine level above 1.5 mg/dL despite normal maternal renal function. The data collected for each ARF case were contributing condition, cause and clinical course of ARF, gestational age and birth weight, age at the time of diagnosis, treatment, presence of perinatal risk factors and need for mechanical ventilation. The frequency of ARF in the NICU during the study period was 3.4%. Premature newborns constituted 31.1% of the cases. The mean birth weight in the group was 2863 +/- 1082 g, and the mean age at diagnosis was 6.2 +/- 7.4 days. The causes of ARF were categorized as prerenal in 29 patients (64.4%), renal in 14 patients (31.1%) and postrenal in 2 patients (4.4%). Forty-seven percent of the cases were nonoliguric ARF. Asphyxia was the most common condition that contributed to ARF (40.0%), followed by sepsis/metabolic disease (22.2%) and feeding problems (17.8%). Therapeutic interventions were supportive in 77.8% of the cases, and dialysis was required in the other 22.2%. The mortality rate in the 45 ARF cases was 24.4%. Acute renal failure of renal origin, need for dialysis, and need for mechanical ventilation were associated with significantly increased mortality (p<0.05). There were no statistical correlations between mortality rate and perinatal risk factors, oliguria, prematurity or blood urea nitrogen and creatinine levels. The study showed that, at our institution, ARF in the neonatal period is frequently associated with preventable conditions, specifically asphyxia, sepsis and feeding problems. Supportive therapy is effective in most cases of neonatal ARF. Acute renal failure of renal origin, need for dialysis, and need for mechanical ventilation were identified as indicators of poor prognosis in these infants. Early recognition of risk factors and rapid effective treatment of contributing conditions will reduce mortality in neonatal ARF.

Acute renal failure (ARF) occurs in 10 per cent to 23 per cent of intensive care unit patients with mortality ranging from 50 per cent to 90 per cent. ARF is characterized by an acute decline in renal function as measured by urine output (UOP), serum creatinine, and blood urea nitrogen (BUN). Causes may be prerenal, intrarenal, or postrenal. Treatment consists of renal replacement therapy (RRT), either intermittent (ID) or continuous (CRRT). Indications for initiation of dialysis include oliguria, acidemia, azotemia, hyperkalemia, uremic complications, or significant edema. Overall, the literature comparing CRRT to ID is poor. No studies of only surgical/trauma patients have been published. We hypothesize that renal function and hemodynamic stability in trauma/ surgical critical care patients are better preserved by CRRT than by ID. We performed a retrospective review of trauma/surgical critical care patients requiring renal supportive therapy. Thirty patients received CRRT and 27 patients received ID. The study was controlled for severity of illness and demographics. Outcomes assessed were survival, renal function, acid-base balance, hemodynamic stability, and oxygenation/ventilation parameters. Populations were similar across demographics and severity of illness. Renal function, measured by creatinine clearance, was statistically greater with CRRT (P = 0.035). There was better control of azotemia with CRRT: BUN was lower (P = 0.000) and creatinine was lower (P = 0.000). Mean arterial blood pressure was greater (P = 0.021) with CRRT. No difference in oxygenation/ventilation parameters or pH was found between groups. CRRT results in an enhancement of renal function with improved creatinine clearance at the time of dialysis discontinuation. CRRT provides better control of azotemia while preserving hemodynamic stability in patients undergoing renal replacement therapy. Prospective randomized controlled studies and larger sample sizes are needed to further evaluate these modalities.

Diuretic therapy in ARF (acute renal failure) is mainly done with loop diuretics, first of all furosemide. Torsemide has a longer duration of action and does not accumulate in renal failure. In chronic and acute renal failure, both diuretics have been effectively applied, with a more pronounced diuretic effect for torsemide. In this study, the effects of torsemide versus furosemide on renal function in cardiac surgery patients recovering from ARF after continuous renal replacement therapy (CRRT) were studied. Twenty-nine critically ill patients admitted to an intensive care unit at a university teaching hospital after cardiac surgery recovering from ARF after CRRT were included in this prospective, controlled, single-center, open-labeled, randomized clinical trial. Inclusion criteria were urine output >0.5 mL/kg/h over 6 h under CRRT. Torsemide and furosemide dosages were adjusted with the target urine output being 0.8-1.5 mL/kg/h. Hemodynamic data, urine output, volume balance, serum creatinine clearance, electrolytes, blood urea nitrogen, serum creatinine, renin, and aldosterone concentrations were measured. Fourteen patients were included in the furosemide group and 15 patients in the torsemide group. Dosages of 29 (0-160) mg torsemide and a dosage of 60 (0-240) mg furosemide were given every 6 h in each group, respectively. The dosage given at the end of the study decreased significantly in furosemide and torsemide treated patients. Urine output, 24 h balance, and serum creatinine clearance did not differ significantly between groups. Urine output decreased in both groups, mostly dose-dependent in the torsemide group. The intragroup comparison of the first time-interval after inclusion with the last time-interval showed a significant increase in serum creatinine and blood urea nitrogen in the furosemide group. Renin and aldosterone concentrations did not show significant differences. In conclusion, torsemide and furosemide were effective in increasing urine output. Torsemide might show a better dose-dependent diuretic effect in ARF patients after CRRT treatment. Serum creatinine and blood urea nitrogen elimination were less pronounced in the furosemide group.

A review of records from the AnTox database of the American Society for the Prevention of Cruelty to Animals Animal Poison Control Center identified 43 dogs that developed increased blood urea nitrogen concentration, serum creatinine concentration, or both as well as clinical signs after ingesting grapes, raisins, or both. Clinical findings, laboratory findings, histopathological findings, treatments performed, and outcome were evaluated. All dogs vomited, and lethargy, anorexia, and diarrhea were other common clinical signs. Decreased urine output, ataxia, or weakness were associated with a negative outcome. High calcium x phosphorus product (Ca x P), hyperphosphatemia, and hypercalcemia were present in 95%, 90%, and 62% of the dogs in which these variables were evaluated. Extremely high initial total calcium concentration, peak total calcium concentration, initial Ca x P, and peak Ca x P were negative prognostic indicators. Proximal renal tubular necrosis was the most consistent finding in dogs for which histopathology was evaluated. Fifty-three percent of the 43 dogs survived, with 15 of these 23 having a complete resolution of clinical signs and azotemia. Although the mechanism of renal injury from grapes and raisins remains unclear, the findings of this study contribute to an understanding of the clinical course of acute renal failure that can occur after ingestion of grapes or raisins in dogs.

Renal failure secondary to effort rhabdomyolysis is uncommon. We report three males age 28, 37 (military sportsmen) and 44 years (sedentary obese), with this condition. Episodes occurred after a training session to run a triathlon, during the course of a mini marathon and during a rescue attempt of a drowning person. All three subjects experienced intense muscle symptoms, hemoglubinuria, oliguria, rise of blood urea nitrogen and a significant rise in muscle enzymes. Creatinekinase reached a maximum of 41 times normal, aspartate aminotransferase a maximum 35 times normal and lactacte dehydrogenase a maximum of 11 times normal. There was a rapid elevation of serum creatinine, reaching values of 6.6 and 9.8 mg/dl on the third day after the physical effort. This parameter had a disproportionate elevation in relation to urea nitrogen, in two subjects. All subjects were managed with saline hydration, sodium bicarbonate and furosemide. Only one required hemodialysis for two days. All normalized their renal function 18 to 48 days after the physical exertion. No subject had other predisposing conditions for acute renal failure.

To adjust adequately for comorbidity and severity of illness in quality improvement efforts and prospective clinical trials, predictors of death after acute renal failure (ARF) must be accurately identified. Most epidemiological studies of ARF in the critically ill have been based at single centers, or have examined exposures at single time points using discrete outcomes (e.g., in-hospital mortality). We analyzed data from the Program to Improve Care in Acute Renal Disease (PICARD), a multi-center observational study of ARF. We determined correlates of mortality in 618 patients with ARF in intensive care units using three distinct analytic approaches. The predictive power of models using information obtained on the day of ARF diagnosis was extremely low. At the time of consultation, advanced age, oliguria, hepatic failure, respiratory failure, sepsis, and thrombocytopenia were associated with mortality. Upon initiation of dialysis for ARF, advanced age, hepatic failure, respiratory failure, sepsis, and thrombocytopenia were associated with mortality; higher blood urea nitrogen and lower serum creatinine were also associated with mortality in logistic regression models. Models incorporating time-varying covariates enhanced predictive power by reducing misclassification and incorporating day-to-day changes in extra-renal organ system failure and the provision of dialysis during the course of ARF. Using data from the PICARD multi-center cohort study of ARF in critically ill patients, we developed several predictive models for prognostic stratification and risk-adjustment. By incorporating exposures over time, the discriminatory power of predictive models in ARF can be significantly improved.

Retinoic acid syndrome (RAS) is the clinical syndrome that occurs after treatment of acute promyelocytic leukemia with all-trans-retinoic acid (ATRA). The patients experience fever, dyspnea, hypotension, respiratory distress, edema and weight gain. Chest x-ray will show pulmonary infiltrates and pleuropericardial effusion. The onset of this syndrome is usually 5-21 days after ATRA treatment when white blood cell counts are rising more than 10,000/cu.mm. The authors have reported a case of RAS. The patient was a 29-year-old man who had been working in a battery manufacturing factory for 7 years. He presented with easily bruising for one month. The initial blood test showed hematocrit of 36.2%, white blood cells count of 3,200/cu.mm with 28% neutrophils, 20% lymphocytes, 2% eosinophils and 50% promyelocytes and platelet of 20,000/cu.mm. Peripheral blood smear revealed numerous fragmented red blood cells. Bone marrow examination showed hypercellularity with abnormal promyelocytes of 95% and bone marrow cytogenetics was translocation of chromosome 15 and 17 [t (15;17)(q22;q12)]. The diagnosis was acute promyelocytic leukemia and the patient was treated with ATRA 45 mg/m2/day per oral starting on day 1 and intravenous idarubicin 10 mg/n2 on day 4, 5 and 6. On day 13, he had a body temperature of 39 degrees C and a dry cough. The white blood cells were rising to 7,400/cu.mm with 16% neutrophils. On day 18, he had oliguria, high grade fever, hypotension, cough with chest pain and white blood cells rose to 21,300/cu.mm with 65% neutrophils and rising of blood urea nitrogen and creatinine. Chest x-ray showed enlarged cardiac shadow with pleural effusion. Echocardiogram revealed moderate amount of pericardial effusion. The diagnosis of RAS was made and ATRA was withdrawn. Intravenous dexamethasone 4 mg every 6 hours and hemodialysis was started. The patient's symptoms improved dramatically and bone marrow examination was in complete remission. He was subsequently given cytarabine and idarubicin as consolidation. This patient had clinical manifestation consistent with RAS, which improved after prompt treatment.
