During a 4-year period, acute renal failure was observed in 27 patients (mean age 65 years) treated by various angiotensin-converting-enzyme (ACE) inhibitors for hypertension, heart failure, or a combination of both. None had significant renal artery stenosis on angiography. Overt volume depletion was present in 21 and hypotension in 12 cases. All patients received diuretic therapy and/or a low-salt diet. Other facilitating factors included cardiac failure, pre-existing chronic renal insufficiency, combined therapy with non-steroidal anti-inflammatory drugs, and diabetes mellitus. Twenty-two patients had two or more of these factors at presentation. A renal biopsy performed in 10 cases showed severe arteriosclerosis of small renal arteries in eight and acute tubular necrosis in five instances. Therapy comprised volume expansion, and withdrawal of diuretics and, except in two patients, of ACE inhibitors. Twenty-one patients recovered normal renal function, two died, and permanent renal damage remained in four. These results suggest that sodium depletion has a critical role in inducing acute renal failure, whose outcome is not always benign. A combination of diuretics and ACE inhibitors should be prescribed with caution, especially in older patients with small as well as with large renal vessel disease.

The occurrence of rhabdomyolysis and acute renal failure associated with cytomegaloviral infection is rare. A 27-year-old housewife was admitted to our hospital with complaints of thirst, muscle weakness, abdominal pain and oliguria. There was no past history of diabetes, drinking, fever or drug habituation and a negative family history. Laboratory tests revealed myoglobinuria, hyper-pancreatic type amylaseuria, hyperglycemia, azotemia and highly increased creatine phosphokinase in the plasma. She was treated with hemodialysis and insulin therapy. Serological studies showed a 4-fold increase in cytomegalovirus antibody titers 4 weeks after admission. Muscle biopsy specimens showed hyaline degeneration and infiltration of T cell lymphocytes in the muscle. Renal biopsy specimens showed acute tubular necrosis and some myoglobin casts. No cytomegalovirus antigen was found in renal specimens by immunofluorescence study. From these results, it was determined that a systemic cytomegalovirus infection triggered pancreatitis which caused diabetic ketoacidosis, rhabdomyolysis and acute renal failure.

The oculo-cerebral-renal syndrome of Lowe is an X-linked recessive disorder characterized by severe mental retardation, congenital cataracts, renal tubular dysfunction, growth retardation, hypotonia, glaucoma, and rickets. Recently, it has been found that serum concentrations of the muscle enzymes are elevated, providing evidence that there is primary muscle involvement in this disorder. The renal functional abnormalities that occur have also been further delineated. Renal tubular dysfunction presents within the first year of life, followed by a serum creatinine level that increases with age. Renal failure generally occurs in the fourth decade of life. We report two patients with Lowe's syndrome who presented with new onset of acute renal failure (ARF). Workup of their ARF established the diagnosis of acute tubular necrosis with evidence of rhabdomyolysis in one case. These patients were treated aggressively with dialysis and had subsequent recovery of renal function to their baseline state. We suggest that patients with Lowe's syndrome who present with an acute change in their renal function should be treated early with vigorous hydration therapy. If dialysis is indicated, it should be initiated. Furthermore, these patients should be promptly evaluated for evidence of rhabdomyolysis with alkalinization of the urine if possible.

Acute renal failure (ARF) is a serious complication in clients who have undergone bone marrow transplantation (BMT). The majority of cases develop as a result of intrarenal damage. Renal ischemia or nephrotoxic drugs, free hemoglobin, and free myoglobin contribute to acute tubular necrosis (ATN), which is the most likely cause of ARF in BMT clients. Nursing care of hospitalized BMT clients is directed toward the prevention of ARF by identifying clients who are at risk, the early diagnosis of renal impairment, and the administration of comprehensive treatment. Nurses play a vital role in the early diagnosis of renal impairment by assessing the client's fluid status, serum and urine electrolyte levels, and daily weights. The nursing role in managing clients with ARF includes preventing drug nephrotoxicity, maintaining fluid and electrolyte balance, preventing infection, and providing emotional support.

From 1976 to 1987 on our Nephrological Unit, 57 patients with IgA nephropathy (IgAN) proven by renal biopsies were found. Three of those presented with acute tubular necrosis (ATN) and glomerulitis, without extrarenal predisposing cause in two; and showed, as prominent manifestation, a severe acute renal failure syndrome (ARFS), needing dialytic treatment. All three had hematuria, which was macroscopic in two and microscopic in one. Thus the prevalence of the association of glomerulitis and ATN was about 5.2%. There was complete recovery of renal functions in all three patients, but the usual symptomatology of IgAN. Two patients presented polymorphonuclear neutrophils infiltration of glomerular capillaries and in one of them, electron-dense deposits on the epithelial side of glomerular basement membrane ("humps") were observed, as well as those identified in the mesangial area. The glomerular polymorphonuclear neutrophils infiltration and endothelial cells proliferation (cases 1 and 3), the presence of "humps" (case 1), high antistreptolysin O (ASO) titers (cases 1 and 2), and low serum complement levels (case 1), suggest the possibility that antigens able to cause postinfectious glomerulonephritis (streptococcal or not) could induce in some individuals, by another immunopathogenetic route, mixed histopathological and clinical features of IgAN and postinfectious glomerulonephritis.

This report is a 17-year-old man with an acute renal failure who complained of nausea, vomiting, bilateral loin pain and abdominal pain after scuffle. Renal biopsy specimen obtained from the left kidney revealed acute tubular necrosis. After recovering renal function he showed extreme hypouricemia (serum uric acid, 0.6 mg/dl) and elevated uric acid clearance (62-78 ml/min). The fractional excretion of uric acid (CUA/Ccr) could not be influenced by either oral pyrazinamide or probenecid. As no other renal tubular or metabolic abnormalities were detected, it is suggested that presecretory reabsorption defect or subtotal defect in uric acid transportation was responsible for the hypouricemia in this patient.

A 21-year-old man developed acute renal failure early in the course of hepatitis A infection and recovered after 17 days. There was no evidence of pre-renal azotemia, the hepato-renal syndrome, ischemic acute tubular necrosis, rhabdomyolysis, or thrombotic microangiopathy. There was, however, transient proteinuria and hypocomplementemia. It would appear that the renal failure resulted from viral-induced injury, either direct or mediated by immune complexes.

Sepsis and aminoglycoside administration remain leading causes of clinical acute renal failure (ARF). In recent years, a number of experimental studies from different laboratories have indicated that specific components of the septic state, most notably fever, endotoxemia, and renal hypoperfusion, can interact to induce synergistic renal damage, acting in concert to produce acute tubular necrosis and ARF. If sepsis-associated ARF has a multifactorial basis, then a number of interventions directed at one or more of its etiologic components could confer protection. In this brief review, evidence to support these pathophysiological and therapeutic considerations are presented.

Two college students who developed reversible acute deterioration in renal function following binge drinking of beer and the use of nonsteroidal antiinflammatory drugs (NSAIDs) are reported. Both patients presented with back and flank pain with muscle tenderness, but showed no evidence of overt rhabdomyolysis. The first case had marked renal failure, with a peak serum creatinine reaching 575 mumol/L (6.5 mg/dL), and acute tubular necrosis was documented by renal biopsy. The second case had only modest elevation in serum creatinine, and renal function rapidly improved on rehydration. The contribution of the potential muscle damage associated with alcohol ingestion to the changes in renal function in these two cases is not clear. However, the major mechanism for the acute renal failure was thought to be related to inhibition of renal prostaglandin synthesis in the face of compromised renal hemodynamics secondary to alcohol-induced volume depletion.

Acute tubular necrosis (ATN) is the most common cause of acute renal failure. Early recognition of patients who are at risk for ATN can prevent or improve the course of ATN. Acute renal failure is classified as prerenal, intrinsic, or postrenal disease. ATN is classified as a type of intrinsic renal disease. The clinical course of ATN is divided into the renal failure phase, diuretic phase, and recovery phase, with each phase having distinct symptoms and laboratory findings. Diagnosis of ATN often is complicated and confusing; understanding of laboratory findings can facilitate the critical care nurse's ability to assess those at risk for ATN. The care and treatment of the patient with ATN is complicated, and specific treatments are discussed in detail. The critical care nurse can play a vital role in identifying the patient at risk, preventing the development of ATN in those at risk, and providing appropriate care for those who develop ATN.
