A patient with nephrotic syndrome and Q-fever endocarditis (confirmed serologically and ultrastructurally) was found to have mesangio-capillary glomerulonephritis with parietal deposits of C3 and IgM and some IgM in the mesangium. Elution studies showed that IgM antibodies reactive against insoluble Coxiella antigens were present in the kidney. Review of the literature suggests that this type of immune complex nephritis may be associated with Q-fever. Possible reasons for the variability of the nephritis associated with infective endocarditis are discussed.

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.

Membranous glomerulonephropathy (MGN) in South African black and mixed race children with the nephrotic syndrome is much commoner than in First-World countries. In this survey of 388 nephrotic children MGN was found in 51.9% of black and 20.9% of mixed race boys, and 25% of black and 5.6% of mixed race girls respectively, but was not present in 53 white and Asiatic nephrotic children. Aetiological or associated factors were documented in 84%: hepatitis B virus infection in 73%, congenital syphilis in 6% and systemic lupus erythematosus, D-penicillamine toxicity and Salmonella infective endocarditis in 1 case each. The prognosis depends on the cause and is much better than for adults with idiopathic MGN. After an average follow-up period of 4.5 years the overall remission rate was 78% and mean time to remission 30 months. One patient with syphilitic MGN died 15 years later; 3 patients are in mild renal failure. Corticosteroids and other immuno-suppressive therapy were ineffective and may do harm. The frequent occurrence of MGN is related to the high prevalence of predisposing infections in the affected population groups, and socio-economic rather than ethnic factors are important.

Nephrotic syndrome is a most unusual complication of infective endocarditis. We report a case of Streptococcus sanguis endocarditis of the tricuspid valve in a patient with a small congenital ventricular septal defect who developed this complication. Severe myocardial depression also occurred and the clinical behaviour and subsequent recovery of this closely paralleled that of the nephrotic syndrome. These unusual associations, their possible interactions and pathogeneses are discussed.

A case is described in which chronic gonococcemia probably resulted in endocarditis, nephrotic syndrome and diffuse immune-complex glomerulonephritis. This is the 11th case of gonococcal endocarditis reported since 1948 and the first report with accompanying immunofluorescence and electron microscopy of the kidney. These studies revealed immune-complex nephritis to be the likely cause of the patient's deteriorating renal function.

To identify the demographic, clinical, and pathologic features and the prognosis of renal disease in a series of patients with infectious or postinfectious proliferative glomerulonephritis (GN), data were collected from records of 76 adult patients admitted from 1976 to 1993 to 2 neighboring suburban hospital nephrology units, whose catchment population consists of patients living in a suburban borough of Paris with a below-average socioeconomic status. Thirty-four patients (45%) were alcoholics, diabetics, or intravenous illicit-drug users. Sixty-six patients presented with acute nephritic and/or nephrotic syndrome. Acute renal failure was present in 56 (76%) and required dialysis in 14. The diagnostic workup comprised at least 1 renal biopsy in each case. The patient's background, site of infection, clinical course, laboratory variables, and, when available, bacteriologic findings were analyzed in each case to interpret the evolution of the disease. Initial renal biopsy disclosed endocapillary GN in 44 patients, crescentic GN in 26, and membranoproliferative GN in 6. Ten patients had endocarditis. Staphylococci and Gram-negative strains, not streptococci, were the most common bacteria identified. The origin of sepsis was mainly the oropharynx (21), the skin (19) and the lung (14); 19 cases involved multiple sites of infection. Eight patients died (11%), and 20 (26%) recovered renal function, but GN followed a chronic course in 38 (50%), rapidly requiring maintenance dialysis in 6. Poor prognostic factors included age over 50 years, purpura, endocarditis, and glomerular extracapillary proliferation. Twenty-six patients underwent repeat renal biopsy 1 month to 11 years after the initial presentation. The main finding, irrespective of the interval since the first biopsy, was that ongoing or new iatrogenic infection acquired during hospitalization was almost invariably acquired during hospitalization was almost invariably associated with developing glomerular proliferative changes. This study shows that infectious proliferative GN remains common, but that its epidemiology has changed from what was observed until 2 decades ago. The responsible bacteria, when identified, now comprise a majority of staphylococci and Gram-negative strains, in contrast to the streptococci which predominated 3 decades ago. Infectious GN affects with increasing frequency patients with an underlying condition responsible for immunosuppression, especially alcoholism, even in the absence of cirrhosis. Destructive glomerular proliferation persists, especially but not exclusively until infection has been eradicated, and despite rescue treatment with corticosteroids and/or cytostatic drugs. Thus, the prognosis is poor, and infectious GN often ends in renal death. Infection continues in this decade to represent a frequent and probably often overlooked cause of end-stage renal failure.(ABSTRACT TRUNCATED AT 400 WORDS)

Streptococcus adjacens has never previously been reported as an etiologic organism of infective endocarditis in Taiwan. We describe a case of severe native valve endocarditis caused by S. adjacens, involving the mitral valve, the aortic valve, and the left atrium, in a 29-year-old woman with nephrotic syndrome on steroid therapy. Blood cultures yielded gram-positive cocci that grew poorly on blood agar but strongly on chocolate agar. Despite aggressive antibiotic treatment, the patients continued to have high fever and progressive congestive heart failure, which necessitated surgical intervention. Symptoms were alleviated after surgery; teicoplanin was continued for 4 weeks and the patient remained symptom-free at the 6 month follow up. To our knowledge, this is the first reported case of bacterial endocarditis involving the left atrium without preexisting myxoma.

Immunological complications of staphylococcal endocarditis are rare but represent a serious event in this condition. The authors report the case of acute tricuspid valve endocarditis in a 38 year old drug addict. The diagnosis was suggested by the presentation of bilateral bacterial lung abscesses with a murmur of tricuspid regurgitation, and confirmed by transthoracic and transoesophageal echocardiography. Bacteriological cultures isolated a methicillin-sensitive staphylococcal aureus. The outcome was complicated by a nephrotic syndrome associated with a glomerulonephritis by deposition of immune complexes and an autoimmune thrombocytopaenic purpura due to acquired anti-glycoprotein IIb IIIa antibodies. Antibiotic therapy led to cure without sequellae of the endocarditis, the nephrotic syndrome and the thrombocytopaenia. This case illustrates the risk of immunological complications during acute staphylococcal tricuspid valve endocarditis and also illustrates the possibility of a favourable outcome with antibiotic therapy alone. However, the potential severity of these complications indicates the need for early diagnosis and strict surveillance of this condition.

Two cases of culture negative endocarditis are presented. In both, Bartonella species could be identified as the causative agent and in one of them Bartonella henselae was very likely. Both cases were accompanied by glomerulonephritis, in one case proven by a kidney biopsy. A nephrotic syndrome may be the first presentation of an endocarditis caused by Bartonella species.

Out of 242 patients treated for systemic lupus erythematosus (SLE) in Novosibirsk for 15 years, valvular lesions and endocarditis were diagnosed in 41(16.9%) patients. Combination of Libman-Sax endocarditis (LSE) with infectious endocarditis (IE) was observed in three patients (two women, one man, age 18-40 year). SLE ran a subacute course in one woman, an acute one--in the other. LSE emerged early in SLE in two patients. All the patients had polyorganic lupus pathology, lupus nephritis with nephrotic syndrome (morphological class IV). Two patients had mitral valve disease, one patient--mitral-aortic disease. The rise of secondary IE was seen after massive immunosuppressive therapy. The diagnosis of secondary IE was made after SLE duration for 10-36 months. At IE diagnosis, all the patients had high titers of blood antiphospholipid antibodies. IE was of staphylococcal origin in two patients and candidosis-induced in one patient. In SLE with IE there was thromboembolic syndrome. LSE and IE have related aspects which should be regarded in clinical practice: possible "IE mask" in LSE, risk of secondary IE in about 10% of LSE patients, prophylactic measures necessary to prevent IE in hemodynamically prominent forms of LSE.
