The aim of the study was analysis of clinical and laboratory markers of non-infectious thrombotic endocarditis (NITE) to facilitate differential diagnosis with infectious endocarditis (IE). 20 NITE patients (8 males and 12 females, mean age 32.3 years) were included in the trial. They had primary antiphospholipid syndrome, secondary antiphospholipid syndrome in systemic lupus erythematosus, nodular polyarteritis, nonspecific aortic arteritis, paraneoplastic NITE in lung and stomach cancer. NITE was also diagnosed in patients with gout and ankylosing spondylarthritis. Clinical and laboratory findings allow to differentiate IE with NITE. The former is characterized by destructive valvular lesions registered at echo-CG, positive hemoculture and arterial embolism. As a rule, NITE is associated with antiphospholipid syndrome and manifests with arterial and venous thrombosis, thrombocytopenia, livedo and presence of antibodies to cardiolipins.

We report an unusual case in which infectious endocarditis presented systemic vasculitis and glomerulonephritis as the initial manifestation of the disease. The patient was a 16-year-old girl with congenital cyanotic heart disease who presented with skin purpura, proteinuria, and hematuria. She had hypergammaglobulinemia, cryoglobulinemia, and positive circulating immune complexes. Renal biopsy revealed crescentic glomerulonephritis. Her serum C3 level, which was initially normal, became decreased, and prednisolone and azathioprine were administered with a tentative diagnosis of systemic lupus erythematosus (SLE). Soon after, she developed fever and renal failure. Blood culture grew Streptococcus pyogenes, and the diagnosis of infectious endocarditis was made. Eight cases of systemic vasculitis and glomerulonephritis associated with infectious endocarditis have been described in the literature. Infectious endocarditis should be included in the differential diagnosis of systemic vasculitis and glomerulonephritis.

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.

Over the last 10 years we have seen 31 children with systemic lupus: 10 (32%) of these have died. The commonest primary determinant of mortality was uncontrolled disease activity (60%), possibly contributed to by late referrals leading to delays in diagnosis and the institution of therapy. Thromboembolic disease was responsible for two deaths and tuberculosis for one. The major contributory factors were nephritis in two patients and myocarditis, endocarditis, lupus pneumonia and CNS disease in one patient each. Concomitant infections, predominantly nosocomial, occurred in a significant proportion of patients (40%) but were only cofactors in mortality. Autopsies were done in three cases. These patterns of death are significantly different from those seen in the developed world, where disease activity has ceased to be an important factor owing to early recognition of cases. Avoiding late referrals and delays in diagnosis can reduce mortality in childhood-onset lupus.

The case of a 27-year-old Japanese woman with type A acute aortic dissection who had been diagnosed with systemic lupus erythematosus (SLE) is presented. The patient also had aortic regurgitation due to non-infective endocarditis and systemic hypertension, and had been maintained on steroid therapy for 15 years. Her twin sister was also diagnosed with SLE. The patient was admitted to emergency due to severe back pain. A chest x-ray showed enlargement of the upper mediastinum. Echocardiography revealed a thickened and deformed aortic valve with aortic regurgitation and dissection of the ascending aorta, but pericardial effusion was not found. Computed tomography demonstrated aortic dissection extending from the ascending aorta to the abdominal aorta. Graft replacement of the ascending aorta and proximal aortic arch was performed under hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully. Aortic dissection complicated with SLE is extremely rare, and this is only the 15th case reported in the English or Japanese literature.

Systemic lupus erythematosus (SLE) is a multisystem disorder with cardiac involvement in about 50% of cases, yet clinically significant lesions are less common. SLE with pancarditis at initial presentation has so far not been reported. We present a rare case of SLE with culture negative endocarditis, reversible left ventricular (LV) dysfunction and mild pericardial effusion. Treatment with steroids showed improvement in cardiac contractile function and mitral valve vegetations disappeared over 3 months. In a case of pancarditis with culture negative endocarditis, SLE as a possibility must be explored. After excluding infective endocarditis, a short trial of high dose corticosteroids effects overall improvement in carditis of SLE.

We describe two female patients with classic systemic lupus erythematosus (SLE) and secondary sicca syndrome associated with topoisomerase I (topo-I, Scl-70) antibody, a specific marker for scleroderma (SSc), which is rarely found in other collagen diseases. During the course of the disease, the sera of these two patients were repeatedly found to be positive for topo-I antibody following a positive screening by ANA-EIA. Neither patient had clinical evidence of scleroderma. One patient remains well nearly 4 years from the first positive serological test. The progression to sicca syndrome in that patient occurred 2 years after having tested positive for antitopo-I antibody. Her frozen serum also tested positive for anti-Scl-70 by the Western blot technique. The other patient, however, died after developing renal and cardiopulmonary complications of lupus, including Libman Sachs endocarditis and pulmonary hypertension. Contrary to the previous patient, the onset of sicca syndrome in this case had preceded the expression of positive antitopo-I antibody. The present cases and other similar previously reported ones are therefore unique in the sense of being a serological challenge to the high specificity of antitopo-I to scleroderma. In addition, they may also represent a new subset of SLE with or without sicca syndrome, which is characterised by the absence of features of scleroderma despite the presence of antitopo-I antibody.

A non-neutropenic patient receiving corticosteroids for systemic lupus erythematosus presented with fever, headache, and seizures. Ring enhancing lesions were found on computed tomography of the brain, and biopsy demonstrated Aspergillus fumigatis. Despite treatment, the patient died, and necropsy revealed Aspergillus endocarditis of the mitral and tricuspid valves.

Cardiac abnormalities has been receiving increased attention in patients with systemic lupus erythematosus (SLE). Cardiovascular system involvement has been found to have a substantial effect on mortality and morbidity in patients with SLE [1]. Recent diagnostic methods using echocardiography examination have allowed the delineation of cardiac manifestations such as myocarditis and myocardial dysfunction, valvular disease, pericardial disease or pulmonary hypertension. A report of two cases is presented: 23-year-old man with acute myocarditis with left ventricular failure and pulmonary oedema as a initial presentation of active SLE, and 51-year-old woman with SLE, antiphospholipid antibodies, with history of cerebral embolic infarction, TIA and venous thrombosis and with mitral valvular dysfunction in course of nonbacterial thrombotic endocarditis. Pulmonary hypertension has been recognised in both patients probably as a result of vasculaopathy and intimal proliferation, vasculitis, thromboembolic disease or parenchymal lung disease in SLE. Recent advances in diagnosis and treatment have substantially improved the prognosis of patients with systemic lupus erythematosus and cardiovascular system involvement [2].

Valvular involvement is the most encountered form of heart disease in systemic lupus erythematosus (SLE). Immunoglobulin and complement deposition in the valvular structure will subsequently lead to Libman-Sacks vegetations, valve thickening, and valve regurgitation. Valvular stenosis is rarely seen. Involvement of the mitral valve is most frequently encountered. Valve disease for most patients is mild and asymptomatic, but patients in whom severe mitral regurgitation develops will present with symptoms of congestive heart failure. A heart murmur will be heard in almost all patients with moderate or severe regurgitation. Transesophageal echocardiography is the most sensitive method to detect the valvular involvement. The valvular changes, the hemodynamic status, or the symptomatology have been shown to progress, remain stable, or sometimes improve. Severe regurgitation, infective endocarditis, and thromboembolic events (mostly stroke or transitory ischemic attacks) are complications of valvular involvement in SLE. In treatment of these patients, prophylaxis of infectious endocarditis, selective antiaggregant and anticoagulant medication, and valve replacement are currently offered. The role of corticosteroid treatment is still unclear in the outcome of SLE valvulopathy.
