A case of 77-year-old female patient with the left atrial ball thrombus without organic mitral valve lesion is reported. She had a history of SLE for one year and experienced pericarditis 2 months before this admission. A 2-D echo examination at that time did not show any abnormal shadow in the left atrium. The repeated 2-D echo on this admission demonstrated peduncular left atrial thrombus of 2 x 1.5 cm in size. Surgical removal of the thrombus was performed successfully. Her cardiac rhythm was atrial fibrillation, but other possible factors related to the intracardiac thrombus formation such as bradycardia, left atrial dilatation or low cardiac output were not noted. Although lupus anticoagulant and anticardiolipin antibody were negative before the operation, participation of SLE in formation of the left atrial thrombus was highly suspected.

Indium-111-antimyosin Fab imaging has been used to indicate myocardial injury. This report describes antimyosin accumulation in two patients with myocardial involvement in systemic lupus erythematosus. Both patients complained of chest pain, and significant stenoses of extramural coronary arteries were ruled out by angiography. The first patient, a 64-yr-old woman, had immunopathologic findings suggestive of systemic lupus. Indium-111-antimyosin Fab imaging showed myocardial tracer uptake. This prompted endomyocardial biopsy providing evidence of systemic lupus. The patient improved under immunosuppressive therapy. The second patient, a 47-yr-old man, had systemic lupus diagnosed by immunopathologic findings and skin biopsy. He had evidence of pericarditis on electrocardiography and echocardiography. Indium-111-antimyosin Fab imaging demonstrated additional myocardial involvement, which supported the initiation of immunosuppressive therapy. Our results suggest that 111In-antimyosin Fab imaging may provide valuable diagnostic information and influence patient management in systemic lupus erythematosus with suspected myocardial involvement.

To assess the cardiological status of patients with long-term lupus nephritis we evaluated 30 patients (mean age 43 +/- 11 years) with lupus nephritis lasting from at least 10 years (mean 15 +/- 5 years). At the time of cardiological evaluation the mean plasma creatinine was 132.6 +/- 11.1 mumol/l and in 28 patients lupus had been quiescent for at least 3 years. Fourteen patients (46.6%) showed one or more cardiac abnormalities: 10 had valvular lesions (1 verrucous endocarditis, 9 thickening and stiffness of one or more valves)--4 patients had regional myocardial akinesis as a consequence of a previous cardiac infarct (one had valvular abnormalities too). One patient had pulmonary hypertension probably secondary to pulmonary vasculitis. No patient had pericarditis. These cardiac abnormalities proved to be statistically correlated with the number of ARA criteria (p = 0.045), the number of lupus flares (p = 0.004), the serum levels of cholesterol (p = 0.04) and of triglycerides (p = 0.025) as well as the duration of hypercholesterolemia (p = 0.005) and of hypertriglyceridemia (p = 0.007). In conclusion, in patients with long-term lupus nephritis cardiac lesions are frequent. The main lesions are non-verrucous valvulopathy (probably a consequence of healing verrucous endocarditis) and cardiac infarct (caused by an accelerated atherosclerosis). On the contrary cardiac lesions caused by active lupus as pericarditis, myocarditis and verrucous endocarditis are rare.

We reported a case of malignant rheumatoid arthritis (MRA) with cerebral infarction associated with a possible cause of lupus anticoagulant. The patient was a 68-year-old woman who had received treatment for rheumatoid arthritis (RA) from 15 to 16 years ago. She consulted to our hospital with a major complaint of right hemiplegia. Brain CT revealed a low density area in the left hemisphere. She was diagnosed as cerebral infarction and hospitalized. Since she was noted to have hypocomplementemia, interstitial pneumonia and pericarditis, she was diagnosed as MRA. Coagulation test disclosed positive lupus anticoagulant (LA). Generally, CNS disorders in MRA are uncommon. Cerebral infarction was complicated in the present case, suggesting the involvement of antiphospholipid antibodies as its pathogenesis.

The occurrence of cardiac manifestations and their relationship with the lupus anticoagulant (LA) in SLE was studied in 74 patients who were followed up for 22 years (median), of which 16 years were after the initial LA testing. Pericarditis was the most common cardiac event occurring in 16 (22%) patients but it did not correlate with LA. Valvular heart disease, coronary artery disease, left ventricular failure and/or cor pulmonale were observed in 16 (22%) patients. Taken together, their occurrence was associated with a history of leg ulcers (odds 3.8, P = 0.028) but not with LA or other common clinical manifestations of the antiphospholipid syndrome. Valvular heart disease in five patients was significantly associated with LA (P = 0.05). Cor pulmonale due to chronic pulmonary embolism was present in two patients with LA. Myocardial infarctions in five patients occurred late in the course of disease but in relatively young patients (mean 43 years). Fatal myocardial infarction in the absence of atherosclerosis in two LA-positive patients supports a pathogenetic role for LA in these cases. In conclusion, of the various cardiac complications in SLE, valvular heart disease and cor pulmonale appear to be connected with the antiphospholipid syndrome. Both conditions should be actively sought in patients with LA to decrease possible adverse events (arterial emboli and right ventricular failure) affecting the patients' prognosis.

We report on a case of C9 deficiency followed by the onset of systemic lupus erythematosus (SLE). A 51-year-old female patient had suffered from repeated urinary tract infections since 1977. In 1980, at 41 years of age, she had proteinuria and facial erythema along with low level of CH50 less than 12.0 U/ml. She was diagnosed as C9 deficiency (C9D) because of C9 protein less than 0.5 mg/dl, C9 activity 0.03% and C8 activity 94% and also SLE was strongly suspicious. Subsequently, she suffered from repeated urinary tract infections. In 1990, she was diagnosed as SLE because of pleuritis, pericarditis and positive anti-nuclear (1:640) and positive anti-DNA antibody (28.0 U/ml) in addition to proteinuria and facial erythema. From the family study, her two sisters showed homozygous C9D (less than 0.5 mg/dl) with hypergammaglobulinemia (2290 and 2230 mg/dl, respectively) and positive anti-nuclear antibody (1:80) in both. Her father also showed heteropygous C9D (1.7 mg/dl) with anti-nuclear antibody (1:640). These results suggest that healthy carriers of C9D may have some abnormalities in humoral or cell-mediated immunity. The possibility was thought that other unrecognized disease associated loci exist in linkage with the C9 allele like that of C4D was speculated. And repeated infections due to C9D may possibly induce B cell activation followed by the occurrence of SLE or related disorders. This case seems to be very valuable with respect to the onset of SLE under a long-term observation of C9D.

The role of laparoscopy in the diagnostic evaluation of ascites of unknown origin was studied in 129 patients. Laparoscopic results were as follows: (1) Carcinomatosis peritonei in 78 (60.5%). Peritoneal biopsies in 76 of these cases revealed malignancy in 67 (adenocarcinoma 62, lymphoma 4, mesothelioma 1) and tuberculosis in 5; specimens were inadequate for diagnosis in 4. (2) Tuberculous peritonitis in 26 (20.2%). Peritoneal biopsies in 24 of these cases revealed tuberculosis in 22 and non-specific chronic peritonitis in 2. (3) Cirrhosis in 7 (5.4%). (4) No gross abnormality in 18 (14.0%). Of the latter, causes of ascites had already been identified in 13 (72.2%), including chronic renal failure in 7, systemic lupus erythematosus in 2, constrictive pericarditis in 2, chronic pancreatitis with chylous ascites in 1, and retroperitoneal lymph node metastasis with chylous ascites in 1. Thus, laparoscopic observation in combination with biopsy established the cause of ascites of unknown origin in 111 (86.0%) of 129 patients. Most of the 18 patients without gross laparoscopic abnormality had underlying disease identified as a cause of ascites; laparoscopy was indicated in these cases to exclude other processes that may also cause ascites.

The clinical manifestations of pediatric systemic lupus erythematosus (SLE) are similar to those seen in adults with SLE with increased frequency of the following features: hepatosplenomegaly, chorea, nephritis, and avascular necrosis. Similarly, pediatric SLE patients are now showing the same improvement in survival as adult SLE patients, and it is no longer felt that the course of childhood-onset SLE is more severe than that seen in adult-onset SLE. Children of mothers with SLE can develop both transient and persistent features of SLE in the neonatal period. Transient features include photosensitive discoid rash, cytopenia, hepatosplenomegaly, myocarditis, and pericarditis; the permanent features include congenital complete heart block, endomyocardial fibroelastosis, and other structural cardiac defects.

Pericardial disorders occurring in connective tissue diseases are not uncommon and may present as acute or chronic pericarditis with or without an effusion. In many instances, a diagnosis of pericardial involvement is not found until autopsy. Echocardiography and other currently employed radiographic techniques have enhanced the ability to make a diagnosis. Approximate frequencies of common connective tissue disorders with pericardial involvement include scleroderma (59%), systemic lupus erythematosus (44%), mixed connective tissue disease (30%), rheumatoid arthritis (24%), and polymyositis/dermatomyositis (11%). Cardiac tamponade or constriction is rare. This article describes a patient with clinical features consistent with mixed connective tissue disease that presented with a pericardial effusion and cardiac tamponade. In addition, a review of pericardial involvement in connective tissue diseases and the occurrence of cardiac tamponade or constriction is included.

Our study ellucidates the utility of endomyocardial biopsy (EMB) in various cardiac-muscle disorders seen in a tropical country like India. The procedure has been successfully performed in 501 patients (572 procedures) at our centre from April 1985 to December 1992. This included 60 infants and children. The indications were dilated cardiomyopathy (DCM) in 214, non-specific aortoarteritis in 91, rheumatic heart disease in 75, restrictive cardiomyopathy in 45, constrictive pericarditis in 14 and miscellaneous in 62 patients. There was no mortality, however, one patient developed cardiac tamponade and another sustained ventricular tachycardia requiring cardioversion. There was transient atrial fibrillation in six patients and all these had acute rheumatic heart disease. Transient complete heart block occurred in six patients with underlying left-bundle branch-block. Histological examination of EMB revealed myocarditis in 34/214 (15.4%) patients in DCM group and helped in following up these cases on immunosuppressive treatment. In the presence of restrictive haemodynamics it could identify amyloidosis in four patients. It was also helpful in differentiating between endomyocardial fibrosis and chronic constrictive pericarditis. In patients with non-specific aorto-arteritis significant histological changes of inflammatory myocarditis were observed in patients especially in congestive heart failure. Furthermore, it was helpful in identifying the nature of cardiac tumour in one patient. Its utility has also been evaluated in disorders, including rheumatic heart disease, peripartum cardiomyopathy and systemic disorders like systemic lupus erythematosis. Even in the absence of cardiac-transplant programmes at national level we have found EMB to be a useful investigation in a tropical country like India.
