The effect of intravenous (i.v.) essential amino acids (EAA) in the treatment of acute renal failure was evaluated in 50 patients. Thirty patients (Group A) received daily 13.4 g of i.v. EAA solution [Nephramine (Don Baxter, McGraw) 250 ml/d]+dopamine i.v. 2 micrograms/kg/min + 20% hypertonic glucose solution 500 ml/d as compared with twenty patients (Group B) who received dopamine i.v. 2 micrograms/kg/min + 20% hypertonic glucose solution 500 ml/d. In Group A patients showed lower daily increase in blood urea
nitrogen
(BUN) (p < 0.05), higher serum total protein and albumin levels on the 15th day of the posttherapy period (p < 0.001), lower complication rate (p < 0.005), lower mortality rate (p < 0.005) and a reverse relation between serum total protein concentration, duration of
oliguria
and age (p < 0.01, r2 = 0.26; p < 0.001, r2 = 0.32). These data suggest that treatment of such patients with i.v. EAA solutions significantly improves survival.

The relative abilities of a series of acyclic polyamine chelating agents containing only
nitrogen
donors (N-donors) to induce the urinary excretion of cadmium has been examined in the rat. The compounds examined include triethylenetetramine dihydrochloride (TRIEN), tris(2-aminoethyl)amine trihydrochloride (TREN), tetraethylenepentamine pentahydrochloride (TETRAEN), and pentaethylenehexamine hexahydrochloride (PENTAEN). Sodium N-methyl-D-glucamine-N-carbodithioate (NaG) was used as a positive control compound. The polyamines induced a significant increase in the urinary excretion of cadmium in rats that had been loaded with cadmium at least 4 d prior to the polyamine treatments. A comparison of these with similar data on macrocylic
nitrogen
donor systems, which form much more stable complexes with cadmium but are also ineffective in enhancing the excretion of cadmium from such aged deposits, suggests that the factors responsible for the relative inefficiency of these compounds may involve either a difficulty in penetrating cellular membranes or a slow rate of reaction with biologically bound cadmium. The occurrence of
oliguria
and anuria following the administration of the several of the polyamines indicates that their use is accompanied by significant renal damage in cadmium-exposed rats.

Aminophenols and halogenated anilines induce nephrotoxicity and mild hepatotoxicity in rats. In this study, the in vivo and in vitro nephrotoxic potential of 4-amino-2-chlorophenol and 2-amino-4-chlorophenol, monochlorinated aminophenols and potential metabolites of 3-chloroaniline, was evaluated. Hepatotoxicity of both compounds was also examined in vivo. Male Fischer 344 rats (four/group) were administered 4-amino-2-chlorophenol hydrochloride (0.4, 0.8 or 1.0 mmol/kg), 2-amino-4-chlorophenol hydrochloride (0.4, 0.8 or 1.2 mmol/kg) or vehicle intraperitoneally (i.p.) and renal and hepatic function monitored for 48 h. Administration of 4-amino-2-chlorophenol (0.8 mmol/kg) induced nephrotoxicity, while only minor changes in kidney function were observed following administration of 0.4 mmol/kg of 4-amino-2-chlorophenol or 0.8 mmol/kg of 2-amino-4-chlorophenol. Increasing the dose of 4-amino-2-chlorophenol to 1.0 mmol/kg or 2-amino-4-chlorophenol to 1.2 mmol/kg resulted in lethality. Nephrotoxicity induced by 4-amino-2-chlorophenol was characterized by diuresis, increased proteinuria, glucosuria, hematuria, elevated blood urea
nitrogen
(BUN) concentration and kidney weight, and marked proximal tubular damage, while 2-amino-4-chlorophenol induced milder effects on renal function and transient
oliguria
instead of diuresis. No hepatotoxicity was observed with either compound at any dose tested. In the in vitro studies, the direct effects of 4-amino-2-chlorophenol or 2-amino-4-chlorophenol on organic ion accumulation, pyruvate-stimulated gluconeogenesis and lactate dehydrogenase (LDH) leakage were determined using renal cortical slices. 4-Amino-2-chlorophenol and 2-amino-4-chlorophenol were almost equally effective in inhibiting organic anion or cation uptake and gluconeogenesis or increasing LDH leakage, although small differences in the minimum effective concentrations were present (minimum effective concentration, 0.01-0.5 mM range). These results demonstrate that 4-amino-2-chlorophenol is a more potent nephrotoxicant than 2-amino-4-chlorophenol in vivo. The results also indicate that the addition of a chloride group to aminophenols enhances renal toxicity.

We describe a case of peripheral T cell lymphoma that is remarkable for its fulminate course and selective targeting of both kidneys. The patient was a 6-year-old girl who was in her usual state of good health until the onset of abdominal pain and fever. She was treated for acute oliguric renal failure and visual disturbances. A renal biopsy was performed. Biopsy findings were interpreted as suggestive of a vasculitic process, and treatment was initiated for a presumptive diagnosis of Wegener's granulomatosis. The patient died 3 days following admission, and autopsy revealed extensive bilateral kidney infiltration by a peripheral T cell lymphoma. The remainder of the body was spared with the exception of mild infiltration of the pulmonary parenchyma and choroid plexus by neoplastic lymphocytes. The neoplastic nature of the disease was confirmed utilizing immunoperoxidase stains and T cell receptor gene rearrangement. Primary renal lymphoma and renal failure attributable to involvement by lymphoma are rare findings that should be considered when other more common causes of renal insufficiency have been excluded. The presenting clinical complaints are generally of short duration, nonspecific, and atypical. Most patients exhibit
oliguria
. Physical examination may reveal hepatosplenomegaly, lymphadenopathy, and flank and/or abdominal mass(es). Laboratory findings frequently include an elevated serum creatinine, blood urea
nitrogen
, lactate dehydrogenase, and a mild proteinuria. Electrolyte abnormalities are variably present. Possible radiographic findings include hypodense or hypoechoic renal lesions and diffuse bilateral renal enlargement. Although the prognosis is dismal, survival may be prolonged utilizing current treatment modalities, and rare patients may be "cured" of disease. The clinical presentation, radiological findings, and prognosis of patients with clinically evident renal involvement by non-Hodgkin's lymphoma are discussed.

Acute renal failure (ARF) is a serious complication following cardiac surgery. This first controlled study was undertaken to verify, if Urodilatin (URO) infusion can revert incipient oliguric ARF after cardiac surgery. We conducted a randomized, double blind trial comparing 7 URO (20 ng/kg/min) with 7 placebo patients. Inclusion criterion was
oliguria
/anuria (< 0.5 ml/kg/hour) refractory to conventional treatment including administration of dopamine and furosemide. No patient in the URO treated group, but 6 patients in the placebo group had to be hemofiltered or hemodialyzed (p < 0.005) during the 7 day treatment period. In the URO group all 7 patients demonstrated a rapid recovery of diuresis after 2 - 8 hours of treatment that persisted throughout the treatment period. In contrast, placebo treated patients remained oliguric. Serum creatinine (SC) decreased in URO treated patients. No adverse effects were observed during URO administration. After termination of URO, 2 patients underwent hemodialysis for elevated blood urea
nitrogen
(BUN) values. In the postoperative follow-up period of 60 days, 4 out of 7 placebo treated patients died while still on hemodialysis. In contrast, all URO patients survived. URO is an effective drug to reverse oliguric ARF following cardiac surgery. Prolonged renal failure and renal replacement therapy can be avoided.

A 41-year-old woman took an overdose of sedatives on the 13th of January, 1994 and remained a sleep in the straight sitting position until she was woken up on the 15th. The next day she consulted our hospital complaining of pain and swelling of her right leg. X-ray examination with contrast medium revealed obstruction of the deep vein of her right leg by a thrombus. On the 17th, her serum urea
nitrogen
was 75.9 mg/dl and creatinine was 5.4 mg/dl accompanied by
oliguria
. The myoglobin value was 27,000 ng/ml in serum and 88,000 ng/ml in urine. She was diagnosed as acute renal failure caused by rhabdomyolysis and hemodialysis therapy was started. She was released from hemodialysis on the 31th of January. The swelling of her right leg disappeared at the end of February. However, her right foot was affected paralysis of the fibular nerve. Electromyogram of her right anterotibial muscle and the test of conduction velocity of right tibial nerve revealed that the neurological disturbance of her right leg was caused by thrombosis of the deep vein. Generally speaking, the swelling of the extremities resulting from rhabdomyolysis caused by crush syndrome is due to a massive shift of body-fluid into the crushed muscles. We believe that when the extremities are compressed (and/or crushed) for a long time, venous thrombosis of the extremities occurs due to compression, there by causing swelling of the compressed extremities, as in this case.

The prevalence of amphetamine abuse and the frequency of emergency department visits for amphetamine intoxication have increased dramatically worldwide. In this study, we retrospectively investigated the relationship between the prognostic features and clinical manifestations among patients admitted to the emergency department of a university hospital for acute methamphetamine intoxication during a 6-year period. Data collected included gender, age, route of abuse, time between drug exposure and arrival at the emergency department, estimated dose, signs and symptoms, laboratory values, and complications. Emergency therapy and cooling procedures were also recorded. After excluding 26 patients with multiple-drug intoxication, 18 patients (male-to-female ratio, 11:7) were include in the analysis. The mean age was 25.6 years. Thirteen patients survived and five died. Patients who died often presented with coma (80% vs 0%, p = 0.002), shock (60% vs 8%, p = 0.044), convulsions (100% vs 23%, p = 0.007),
oliguria
(80% vs 0%, p = 0.002), and high body temperature (41.4 +/- 0.5 degrees C vs 39.4 +/- 2.1 degrees C, p = 0.005). Furthermore, patients who died had significantly higher concentrations of blood urea
nitrogen
(8.7 +/- 2.1 vs 5.6 +/- 2.0 mmol/L, p = 0.01) and serum creatinine (212 +/- 71 vs 115 +/- 27 mumol/L, p = 0.033), and lower values of arterial pH (7.12 +/- 0.12 vs 7.34 +/- 0.10, p = 0.03), than those who survived. In the fatality group, the most common complication was rhabdomyolysis with acute renal failure (5 of 5); multiple organ failure resembling that from heatstroke was the leading cause of death from acute methamphetamine intoxication. In conclusion, the adverse prognostic features in patients with acute methamphetamine intoxication include coma, shock, convulsion,
oliguria
, and high core temperature. Acidosis, volume depletion, and ischemic renal damage were potential risk factors for development of acute renal failure in these patients.

Pneumoperitoneum (PP) is associated with
oliguria
and increased plasma arginine vasopressin (AVP) levels. This study investigated the role of AVP in the pathogenesis of
oliguria
due to PP. Anesthetized and ventilated rats (n = 12) were subjected for 1 h to carbon dioxide PP with an intra-abdominal pressure of 8 mmHg or, as control, at 0 mmHg, before the determination of plasma AVP level. Another group of rats (n = 48) subjected to PP or control conditions was pretreated with the AVP V2 receptor antagonist, OPC-31260 (5 mg/kg), or vehicle, and their renal parameters were measured. Glomerular filtration rate (GFR) was determined by inulin clearance in an additional group of rats (n = 12) subjected to PP with or without pretreatment with OPC-31260. Rats subjected to PP had higher plasma AVP levels than did controls (17.3 +/- 8.1 pg/ml vs 1.5 +/- 0. 6 pg/ml, P < 0.05). In rats pretreated with vehicle, PP decreased urine output, excretion of water, and urea
nitrogen
, leading to reduced serum osmolality and serum sodium levels as well as elevated blood urea
nitrogen
levels. OPC-31260 pretreatment improved urine output, excretion of water, and urea
nitrogen
, thereby preventing changes in serum osmolality, serum sodium levels, and blood urea
nitrogen
levels. OPC-31260 pretreatment did not affect GFR. Results suggest that plasma AVP contributes to the
oliguria
due to PP. OPC-31260 may be useful in treating the water retention associated with PP.

When cyclophosphamide (CY) (100-120 mg kg(-1)) was administered intravenously (i.v.) to normal F-344 rats,
oliguria
occurred over the 5-day observation period. Conversely, in rats bearing matrix metalloproteinase-9 (MMP-9) producing 13762NF mammary adenocarcinoma (MTLn3 clone), polyuria occurred chiefly during the first 24 h after CY treatment. In parallel with urine volume, a decrease in the urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG) was observed during the first 5 days after CY treatment in normal rats, but it increased in MTLn3-bearing rats. No elevation in blood urea
nitrogen
(BUN) or serum creatinine (Cr) values was observed for either group. Both urine volume and urinary excretion of NAG after CY treatment were lower in rats bearing the MTC clone (lower production of MMP-9) than for those bearing the MTLn3 clone. In the case of treatment with cisplatin (CDDP, 4-6 mg kg(-1)), urine volume, urinary NAG excretion and BUN and serum Cr values all increased in normal rats and were all found to be higher in MTLn3-bearing rats than in normal rats. The diuretic response to these drugs in tumour-bearing (TB) rats may be associated with MMP-9 produced by the tumour cells. This report suggests that the nephrotoxicity due to anti-cancer drugs may change when the drugs are used for the treatment of patients bearing a MMP-9-producing tumour.

Prophylactic hemodialysis has been employed in the treatment of 15 patients with acute renal failure due to acute tubular necrosis (12), bilateral renal cortical necrosis (two), and poststreptococcal glomerulonephritis (one). Dialyses, usually lasting six hours each, were begun before clinical evidence of uremia developed in each patient and/or before the nonprotein
nitrogen
reached 200 mg.%, and were repeated daily or often enough to maintain the nonprotein
nitrogen
below 150 mg.%. The hypothesis underlying this technic postulates (1) that wasting, sepsis and impaired wound healing in these patients may reflect tissue injury by the same dialyzable toxic agents which produce the uremic symptoms that are readily reversible by dialysis, and (2) that repeated dialyses should therefore prevent both clinical uremia and the later, often lethal sequelae. The results contrast dramatically with our own past experience in treating patients with acute renal failure with a carefully executed medical regimen together with hemodialysis on conventional indications. Except in one instance of crush injury with progressive intracerebral damage, and one brief occasion in another individual, these patients experienced a stable, convalescent clinical course, remained free of uremic symptoms or chemical imbalances, ate at least three meals daily which were unrestricted in amount and composition, and were ambulatory between dialyses unless confined to bed by associated disease. Wounds healed well. Infection either did not occur, or subsided after appropriate therapy. Fluid restriction was liberalized by means of ultrafiltration with dialysis. Regional heparinization of only the extracorporeal circuit eliminated actual or impending bleeding as a contraindication to dialysis. Chronic vessel cannulation made the frequent dialyses possible, but may have provided the route for repeated, transient bacterial contamination of the blood stream in the first hour of many dialyses. Marked anemia, despite reticulocytosis, moderate to mild weight loss and some mental deficit persisted in spite of the general clinical improvement and well-being. Three patients with tubular necrosis died after seven, 11 and 26 days of
oliguria
; both patients with bilateral renal cortical necrosis also succumbed, on the seventy-third and ninety-second days of renal failure, and after 29 and 40 dialyses, respectively. At autopsy, evidence of sepsis was conspicuously absent. The remaining 10 patients survived. Thus some, but not all, clinical manifestations of acute renal failure appear to be favorably influenced by prophylactic dialysis treatment. Our initial experience in this group of 15 patients does not of course prove that freedom from complications and a significantly better outlook for survival can be assured to patients with acute renal failure by these methods. However, it seems to offer a reasonable hope of this possibility which we cannot attach to management by medical measures alone, or by dialysis on conventional indications. If this hope is realized in greatly extended, subsequent series, then it seems inevitable that some form of prophylactic dialysis, or some equally effective alternative, should be adopted in treating the majority of patients with acute renal failure.
