This syndrome is characterized by a hyper-triglyceridemia associated with a deficiency of the plasma lipolytic activity induced by heparin infusion. All signes ascribed to familial lymphohistocytosis were found in this patient. When a diagnosis of acute reticulosis in children is made, such biological characteristics should be searched for. Since in systemic lupus erythematosus an acquired and analogous type of hyperlipidemia has been described, the hypothesis of an immunological pathogenesis in familial lymphohistiocytosis may be plausible.

Patients with systemic lupus erythematosus may develop premature atherosclerosis, notably coronary artery disease. A group of 10 patients with peripheral vascular disease presenting with intermittent claudication or gangrene were studied from a group of 563 patients followed prospectively at the Wellesley Hospital Lupus Clinic. These 10 patients were compared with the next lupus clinic patient matched for age and sex, with respect to demographic characteristics and risk factors. The patients and controls did not differ significantly in lupus activity criteria count, partial thromboplastin time, the number with antibody to cardiolipin, number receiving steroids or mean steroid dose, family history of atherosclerosis, hyperlipidaemia, smoking, hypertension or use of oral contraceptives. The risk factors for developing peripheral vascular disease were a longer duration of systemic lupus erythematosus and a longer duration of use of steroids. Eight of the 10 patients had coexistent coronary artery disease or transient ischaemic attack.

Lid tumors appear to invite the physician to make a diagnosis at first glance. This poster displays examples of lid tumors that occur in the context of malignancies, inflammatory and metabolic diseases and phacomatoses. The most frequent primary sites in metastatic eyelid tumors are the breast, the lung and cutaneous melanoma. Because of their comparatively low incidence and variable appearance these lid tumors are, at least in the beginning, often misinterpreted. Careful differential diagnosis may help in avoiding the diagnostic pitfalls of the masquerade syndromes. Lid tumors associated with sarcoidosis, lupus erythematosus discoides, lupus vulgaris, syphilis are briefly mentioned. Xanthelasmas occur more frequently in diabetics than in the normal population. About 5% of patients with xanthelasma suffer from hyperlipidemia. Neurofibromas and cavernous hemangiomas of the lid may accompany von Recklinghausen's and Sturge-Weber's diseases.

We investigated the anticardiolipin antibody (ACA) in a series of patients with cerebral infarction without systemic lupus erythematosus (SLA). Clinical and laboratory data were assessed from a series of 250 non-SLE patients with cerebral infarction who visited our clinic from 1988 to 1990. The concentration of anticardiolipin IgG antibody was measured by an enzyme-linked immunosorbent assay technique. An elevated ACA level was defined as one which was greater than 3 standard deviations above the mean level for normal controls. We examined the CT findings and risk factors for stroke such as hypertension, diabetes mellitus, hyperlipidemia and cardiac disease. Laboratory data such as the platelet count, the presence of lupus anticoagulant and a biologic false-positive test for syphilis were also investigated. Among the 250 patients with infarction, IgG ACA was detected in 22 (8.8%). There was no significant difference in incidence of ACA between the patients with cerebral thrombosis and those with cerebral embolism. On CT scan, multiple cerebral infarcts were noted in 18 of the 22 patients. As regards the location of the infarct, the cerebral cortex together with the basal ganglia was more common than isolated lesions of the cortex or basal ganglia. Concerning the risk factors for stroke, hypertension was noted in 12, diabetes mellitus in 2, hyperlipidemia in 2 and cardiac disease in 2. Lupus anticoagulant and thrombocytopenia were not detected in any of the cases. A biologic false-positive test for syphilis was observed in one case. Dementia was present in 12 of the 22 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

In order to establish the association between mitral valve prolapse (MVP) and the incidence of thromboembolic disease of the brain we reassessed 36 patients (less than or equal to 50 years old) who were hospitalized during 1983-85 because of cerebrovascular accidents. The patients underwent complete physical and neurological examinations, blood tests including coagulogram and two-dimensional echocardiogram. The control group comprised 117 patients without cerebrovascular events. In the study group, 4 patients (11.1%) had MVP compared with 10 (8.5%) in the control group. Of these four, only one male did not have any risk factor for thromboembolic event; among the other three the risk factors were systemic lupus erythematosus, hyperlipidemia, diabetes, hypertension and pregnancy. We conclude that our results are in accordance with most of the literature that MVP is not a risk factor for thromboembolic disease except in Greek and Italian populations, which are ethnically more homogeneous than other Western societies studied.

The majority (about 75%) of patients who suffer from acute pancreatitis do so as a consequence of gallstones or alcohol abuse. The other 25% of patients often present difficult diagnostic problems. Over several years the author has accumulated a series of patients with remedial causes of pancreatitis. They include a group of congenital conditions such as pancreas divisum, choledochal cysts and congenital abnormalities of the pancreatic ductal system. Patients who have had pancreatitis and who have an intact gallbladder often have stones that are difficult to identify. Repeated attacks of pancreatitis in the absence of any other apparent cause justifies cholecystectomy, which will often identify the cause so that recurrence can be prevented. A group of nonanatomic causes are also known. They include hyperlipidemia, drugs and toxins, certain systemic illnesses such as systemic lupus erythematosus, pregnancy, hypercalcemia, hereditary causes and occasionally cancer. In his lecture the author reviews the various etiologies of acute pancreatitis and describes an algorithm that can be used when the diagnosis is difficult.

Between 1974 and 1988, 7 myocardial infarctions occurred in 6 (4 men, 2 women) out of 400 systemic lupus erythematosus patients. Their ages at the onset of lupus ranged from 13 to 44 years (m = 26). Four had renal involvement. Control of lupus in all 6 patients required high-dose steroids (at least 1 mg/kg/d of prednisone). Myocardial infarction occurred 4 to 19 years after the onset of lupus (m = 13). One patient died of cardiogenic shock. When the infarction occurred, only one patient was undergoing a lupus flare, while the disease was quiescent or slightly active in the 5 others. One patient had no risk factors for atheroma but had been taking steroids for 10 years. Among the other 4, one had hypertension, another had hyperlipidemia and 3 were smokers; they had been on steroids for 2, 4, 11 and 13 years. Coronary angiogram showed occlusion in all 4, but atheroma in only 2 patients. Lupus anticoagulant was present in 3 of these 4 patients. The mechanisms responsible for coronary occlusion in lupus patients are probably complex and interwoven. In addition to "classical" factors (i.e., vasculitis or steroid-induced atheroma), other factors, such as antiphospholipid antibodies and/or smoking, may play an important thrombogenic role.

Lupus anticoagulants and anticardiolipin antibodies are antiphospholipid antibodies (APLAb) with related antigenic specificities and are newly recognized markers for an increased risk of thrombosis. We studied 48 patients who presented with cerebral or visual dysfunction associated with APLAb to help clarify the diagnostic, clinical, laboratory, radiologic, and pathologic features in these patients. Most patients presented with transient cerebral ischemia or cerebral infarction. Recurrent and stereotypic events were frequent. Visual disturbances resulted from amaurosis fugax, retinal arterial or venous occlusion, occipital ischemia, diplopia, and migraine-like disturbances. Three patients presented with severe atypical classic migraine. Recurrent infarcts of brain and eye were significantly associated with the presence of cigarette smoking, hyperlipidemia, and a positive antinuclear antibody. During 44.4 patient-years of prospective follow-up, the combined stroke and systemic thrombotic event rate was 0.27 events per patient-year and was 0.54 events per patient-year if TIA and death were included. Forty (83%) of the patients did not have systemic lupus erythematosus (SLE). Thrombocytopenia was present in 15 (31%) and a false-positive VDRL in 11 (23%) of the patients. Cerebral angiography was normal or revealed large-vessel occlusion or stenosis without changes suggestive of vasculitis. Patients with only transient dysfunction generally had normal radiologic studies, including angiography. Organs and arterial vessels studied pathologically revealed thrombotic occlusive disease without vasculitis. APLAb are strongly associated with an immune-mediated thrombotic tendency, generally in the absence of SLE. Other stroke risk factors may add to the risk of recurrent ischemic events in patients with APLAb.

The pathogenesis of avascular necrosis of bone (ANB) was investigated in 111 patients with systemic lupus erythematosus (SLE) (24 with ANB, 87 without ANB); patients' ages, corticosteroid treatment, clinical and laboratory features associated with SLE, and haemostatic profiles were all taken into account. The mean ages of patients with and without ANB at the time of diagnosis of SLE was 24.1 and 31.2 years respectively. The mean maximal daily dose of prednisolone in the group with ANB was 50.8 mg, which was significantly higher than the dose (41.8 mg) in the group without ANB. Disease features of SLE, such as Raynaud's phenomenon, hyperlipidaemia, nephrotic syndrome, hypertension, and disease activity, were not found to be related to ANB. The percentage of patients who had lupus anticoagulant as well as a shorter activated partial thromboplastin time was greater in those with ANB than in those without. Multiple factors may be involved in the pathogenesis of ANB in SLE, and it is suggested that haemostatic abnormalities, which could be influenced by corticosteroids and young ages, play some part in the development of ANB.

Cardiovascular manifestations develop in the majority of SLE patients at some time during the course of their illness, the most common being acute fibrinous pericarditis and pericardial effusion. Echocardiography has demonstrated an increased incidence of pericardial effusion, even in those who have minimal symptoms. Chronic adhesive pericarditis, pericardial tamponade, and constrictive pericarditis occur rarely. While myocarditis is commonly noted at autopsy, it is often silent clinically. Diagnosis during life can be confirmed only by endomyocardial biopsy. Electrocardiographic changes are often nonspecific. Endocarditis with superimposed nonbacterial verrucous vegetations (Libman-Sacks) is noted in more than 40% of hearts at autopsy, but is rarely diagnosed during life. Valve dysfunctions, such as aortic stenosis, aortic insufficiency, mitral stenosis, and mitral insufficiency, occasionally manifest during life and rarely may necessitate surgery. Atrial and ventricular arrhythmias, first degree AV block, and acquired CHB occur in association with pericarditis, myocarditis, vasculitis, and myocardial fibrosis, respectively. CCHB developing in newborns of mothers with SLE, particularly those who have an antibody to soluble tissue ribonuclear protein RO(SS-A), is increasingly being appreciated by both pediatric cardiologists and rheumatologists. Recently, severe coronary atherosclerosis resulting in angina pectoris and/or myocardial infarction in young adults has been noted, particularly in those who had developed risk factors such as hypertension and hyperlipidemia while receiving prolonged corticosteroid therapy. Rarely, coronary arteritis may produce similar symptoms. Congestive heart failure of either single or multiple etiologies carries an ominous prognosis. It remains a cause of high morbidity and mortality unless recognized early and treated properly. Extracardiac vascular manifestations of SLE include telangiectasia, vasculitis, livedo reticularis, Raynaud's phenomena, and thrombophlebitis, all of which may occur either alone or in different combinations. Evidence is now slowly accumulating that substantiates that immune complex deposition, complement activation and subsequent inflammatory reaction is responsible for the majority of the cardiovascular manifestations of SLE, for example, pericarditis, myocarditis, endocarditis, coronary arteritis, coronary atherosclerosis, and systemic and pulmonary vasculitis.(ABSTRACT TRUNCATED AT 400 WORDS)
