We studied 11 patients who had visceral abscesses and in whom acute renal failure developed. All renal biopsies showed a diffuse proliferative and crescentig glomerulonephritis. In seven patients blood cultures were repeatedly negative. Endocarditis could be ruled out in six patients. Seven patients had circulating cryoglobulins; serum complement levels were normal in seven and decreased in four; circulating immune complexes were found in the three patients studied. The evolution of the glomerulonephritis, documented by serial biopsies, closely paralleled the course of the infection. A complete recovery of renal function occurred in four cases in which a rapid and complete cure of the infection was obtained. Of five patients in whom the infection was not cured, four died, and chronic renal failure developed in one. In two patients in whom therapy was delayed, chronic renal failure also developed. Deep suppuration, even in the absence of bacteremia, may be responsible for a severe but possibly reversible glomerulonephritis with circulating immune complexes.

We reported a 29-year-old man with active endocarditis complicating aortic and mitral valve regurgitation. The echocardiogram showed a mycotic aneurysm at aortic valvular annulus and a aneurysm of mitral valve. Heart failure was progressive and caused anuria. Prior to emergent double valve replacement, 2,500 ml of water was removed. Then hemodynamics became stationary. Urination was good during and after operation. In this case, complicating acute renal failure, dehydration with extracorporeal ultrafiltration method was very effective for improvement of hemodynamics.

There have been only a few investigations that have considered renal disease or any disturbance of renal function in the calculation of risk in cardiac surgery. Risks of cardiac surgery have to be considered for renal disease without direct connection to heart disease (e.g., infections of the kidney and of the urinary tract, primary and secondary glomerulonephritis, parenchymal renal disease, and impaired renal function of unknown origin), as well as in renal disease with concomitant influence on heart and kidney (e.g., infective endocarditis, arterial hypertension, systemic disease of heart and kidney such as with diabetes mellitus, disturbance of kidney function or electrolyte balance due to heart failure). In most cases, the problem is solved by therapeutic intervention and postponement of cardiac surgery. A limited or negative operative indication is found with untreatable infection of the kidney or urinary tract, with untreatable nephrotic syndrome, in advanced renal disease with heart transplantation, as well as in case of severe arterial hypertension with possible organ complications, and in advanced diabetes mellitus with ESRD and multiorgan involvement. After cardiac surgery, acute renal failure represents a critically important complication. Primary therapeutic procedures must include prophylaxis of hemodynamic unstable situations, as well as prophylaxis of infectious complications. Cardiac surgery in dialysis patients and post-transplant patients is basically possible and only has a slightly increased risk compared to patients with normal renal function. Seventy-seven dialysis patients were operated (49 aorto-coronary bypass operations, 19 single-valve and multiple-valve replacements, five patients with valve replacement and aorto-coronary bypass, and four other cardiac surgical operations). Only in valve replacement, was mortality significantly higher than in renal healthy persons, the main causes of death being cerebrovascular complications and septicemia.

The kidney diseases in patients with bacterial endocarditis and intravenous drug addicts (IVDA) tend to be of glomerular origin. Interstitial nephritis has been related to drug toxicity and only occasionally has it been described in other associations. We describe a 27-year-old patient IVDA with tricuspid endocarditis caused by S. Aureus whose first manifestations was acute renal failure. The renal biopsy showed an interstitial nephritis. It was treated with antibiotic and hemodialysis, obtaining the cure and normal levels of plasmatic creatinine.

A successfully treated case of fungal endocarditis for native aortic and mitral valves was reported. A 56-year-old male was admitted with high fever, dyspnea on exertion and oliguria. Infective endocarditis, urinary tract infection and acute renal failure were most suspected by findings of physical examination and urinalysis, but repeated blood cultures were sterile. In the course of treatment for urinary tract infection, high fever and leucocytosis recurred and then blood cultures were positive for Candida parapsilosis. Despite intensive antifungal therapy, blood cultures were consistently positive for Candida parapsilosis. Echocardiogram showed vegetation on the aortic and mitral valve. Aortic and mitral valve replacements with prosthetic heart valves were carried out on April, 1986. Cultures of the vegetation on the mitral valve revealed Candida parapsilosis. Intensive administration of antifungal drug was done postoperatively. Postoperative course was uneventful and he was discharged in excellent condition on the 84th postoperative day. During follow-up period of 1 year, the patient has been doing very well and there were no sign of recurrence of fungal infections.

In 2711 patients with heart valve replacement performed between 1965 and 1986 the cumulative incidence of prosthetic valve endocarditis (PVE) was 1.19 +/- 0.24% (n = 61). In patients operated on before 1976 (group A; n = 583) early PVE was observed in 3.43%, and in patients operated on between 1976 and 1986 (group B; n = 2128) in only 0.42%. PVE after the 60th postoperative day occurred with a linear incidence of 0.21 events per 100 patient-years (A: 0.11%; B: 0.27%). In 54% of PVE cases the aortic, and in 34% the mitral was involved; in 12% both left-sided prostheses were involved after double valve replacement. In the four weeks before the manifestation of initial symptoms of PVE, bacterial infections and diagnostic or therapeutic interventions had occurred in 74.2%. All interventions had been performed without endocarditis prophylaxis. Diagnosis of PVE was established in 57% by history and clinical examination, in 20% by microbiologic examinations and in 12% by echocardiography. Due to improved diagnostic methods and earlier surgical intervention, mortality declined during the follow-up period from 81% (1965-1970) to 18% (1981-1986). The prognosis was worse in patients who developed therapy-resistant heart failure due to hemodynamically significant prosthetic valve malfunction, or who had sepsis that persisted for more than 72 hours despite antibiotic therapy, major septic embolism or acute renal failure. The retrospective prognosis was more favourable for patients with early valve re-replacement than for patients who had been treated medically alone.

Five patients with chronic bacterial infections (two with osteomyelitis, two with infected vascular prostheses, one with soft tissue abscess), but without endocarditis, developed signs of glomerulonephritis and renal failure. Histological examination in three revealed mainly proliferative glomerular alterations. The outcome of glomerulonephritis paralleled the course of infection. Recovery or marked improvement occurred in three patients in whom the infection was cured, one case with smoldering infection eventually developed endstage renal failure, and one with persistent infection died from severe complications with acute renal failure. If renal failure occurs in the setting of suppurative infection, so-called infection-associated glomerulonephritis must be considered. Prompt and effective eradication of infection has an important bearing on the course of renal function.

Splenic and renal tissues from a 61-year-old man with subacute bacterial endocarditis and acute renal failure were studied. Immune complex deposits were found both within glomeruli and splenic venous sinus basement membranes, substantiating the systemic nature of the immune injury in this disorder. The splenic deposits may, in part, be responsible for the splenomegaly often present in endocarditis.

The effects and toxicity of tobramycin were assessed in 26 patients receiving high-dose (approximately 8 mg/kg/d) therapy for pseudomonal endocarditis or conventional-dose (approximately 3 mg/kg/d) therapy for various systemic Gram-negative infections. Patients in the high-dose group received an average of 29.5 g of drug over 49 days and the dosage was adjusted to maintain peak serum concentrations of 15-20 mg/l. In the conventional-dose group, patients received an average of 8.6 g of tobramycin over 26.7 days and the dosage was adjusted to achieve peak concentrations of 4-10 mg/l. Clinical evidence of acute renal failure was not apparent in any patient. Five of seven patients in the high-dose group, for whom audiologic data was available, exhibited loss of hearing sensitivity in the high frequency range, but no patients sustained significant reduction in hearing in the conversational frequency range. Patients receiving high-dose tobramycin do not appear to be at greater risk for development of nephrotoxicity than do patients receiving conventional-dose therapy.

Acute renal failure developed in a diabetic with staphylococcal arthritis and septicaemia in the absence of endocarditis. Renal biopsy showed proliferative glomerulonephritis and there was evidence of alternative pathway of complement activation. Renal function recovered following haemodialysis for 2 months. The association of glomerulonephritis with staphylococcal infection is reviewed.
