[Lupus disease with antinuclear antibodies of the nucleolar type. Apropos of a series of 13 cases].

An exclusive or predominant nucleolar location of antinuclear antibodies is rare in the course of lupus disease: less than 1 p. cent of our patients. Thirteen cases of lupus disease with exclusive or predominant antinucleolar antibodies are analyzed: clinically, the only difference from other lupus diseases is the absence of pleurisy (p less than 0.03) and the frequent thrombopenia (p = 0.05). A proliferative glomerular lesion was found 4 times on renal biopsy. No patient presented any indications of overlapping sign with sclerodermia, polymyositis or Gougerot-Sjögren syndrome which are usually associated to a nuclear fluorescence of nucleolar type. 11 out of 13 patients have natural anti-DNA antibodies, including 9 with a very weak titer. Six patients present cytoplasmic anti-organic antibodies. Four patients have antibodies which precipitates on gelose, identifying nuclear or cytoplasmic antibodies: in 1 instance anti-SS-B et SS-A (Ro), in 1 instance anti-ribosomes associated with anti-ADN, in one instance anti-DNA. No serum contained anti-histones antibodies. The study of the sensitivity of nucleolar antigens to digestion by various enzymes (DNAse, RNAse and trypsin) showed that antinucleolar sera could be placed into three groups: 8/10 recognize a ribonucleic antigen, 1/10 a ribonucleoproteic antigen and 1/10 an antigen resisting to various enzymatic digestions. Therefore, in spite of its rarity, an exclusively nucleolar fluorescence should not rule out the diagnosis of lupus disease.

[Clinical and developmental aspects of Horton's disease. Retrospective study of 100 cases].

100 patients, from three internal medicine departments, were the subject of a retrospective study concerning the clinical manifestations and the evolution of Horton's disease. The mean age is 71 years, with a 2/1 female predominance. A temporal artery biopsy was obtained in all cases. Besides the prevalence of clinical symptoms (headaches: 80 p. cent; weight loss: 78 p. cent; fever: 65 p. cent; local inflammation: 52 p. cent, frequent pseudo-polyarthritis: 40 p. cent and sometimes severe ocular localizations (11 p. cent blindness), other signs should be emphasized: muscular pain (49%), skin hyperesthesias (37%), painful jaw (33%), etc. The inflammatory syndrome dominates the biological picture (96%); the alkaline phosphatases are increased in 37 p. cent of cases. Temporal artery biopsy was positive in 82 p. cent of cases, which confirms the excellent sensitivity of this test, preceded by a Doppler study in only 28 cases. Extension of the inflammatory process to the large vessels was demonstrated 8 times, on clinical data. Finally, the mean length of the steroid treatment was two years with 14 relapses and 8 deaths.

[Visceral lesions in hypereosinophilia].

The hypereosinophilic syndrome is an ill-defined nosological entity with predominant risks of cardiac and/or neurological lesions. In the light of new data on the effector cytotoxic effects of eosinophils, we have tried to establish new criteria of severity by purifying the circulating eosinophils of 14 patients with hypereosinophilic syndrome and testing their toxicity. This study has revealed the existence of low density ("hypodense") eosinophils with potential cytotoxicity in vitro. The worst clinical forms of the syndrome were observed in the group of patients with positive eosinophil toxicity tests. The significance of these cellular changes (hypodensity, eosinotoxicity) and their relationship with the clinical manifestations are discussed.

[Deep venous thrombosis in Behçet's disease. 106 localizations in a series of 177 patients].

A retrospective study of 177 patients (137 male, 40 female) with a disease that fulfilled the criteria of complete or incomplete Behçet's disease showed 106 thrombotic lesions of a venous trunk in 62 (35%) of these patients, superficial phlebitis and retinal vein thrombosis excluded. The incidence of thrombosis was unrelated to race and sex. The venous lesions were single in 38 cases and multiple in 24 cases, including 4 with more than 4 territories involved. Arterial lesions were also present in 7 cases. The lesions were located in the sural (n = 63), iliofemoral (n = 14), inferior vena cava (n = 13), superior vena cava (n = 3), axillary (n = 2) and cerebral (n = 13) veins or territories. Thrombosis developed during the first 4 years of Behçet's disease in one half of the patients. It preceded the aphthosis by 1 to 10 years in 11 cases, was concomitant with it in 15 cases and appeared more than 10 years after the diagnosis in 8 cases. Pulmonary embolism occurred in 11 patients, requiring clipping of the vena cava in 2, but it was never lethal. However, 2 of the 5 patients who died had venous thrombosis (Hughes Stovin syndrome). Thirty-eight patients could be followed up for 12 to 192 months (mean 43) under anticoagulant or antiplatelet therapy. Five vascular recurrences (13%) were observed, 2 of them (1 arterial graft thrombosis, 1 cerebral thrombosis) under anti-vitamin K agents. Cerebral thrombosis (9 men, 4 women) accounted for 27% of the neurological lesions; its prognosis was favourable in the 7 patients successfully treated with anticoagulants. Thrombosis could not be explained. Haemostasis studies showed a decrease of fibrinolytic activity compared to a group of normal subjects and an increase in fibrinogen, factor VIII and Willebrand's factor levels; these abnormalities did not seem to be specific. Thus, phlebitis truly is an element of Behçet's disease. Until its mechanism is better understood, effective anticoagulant therapy in cases with proven thrombosis and preventive antiplatelet therapy in the other cases seem to be rational measures.

Systemic necrotizing angiitis with asthma: causes and precipitating factors in 43 cases.

Causes and precipitating factors for systemic necrotizing angiitis (NA) with asthma were sought in 43 patients, focusing on a history of vaccination and desensitization. Mean age of patients was 43.2 years. Diagnosis was based on histopathologic findings in 25 patients, arteriography in 2, and clinical criteria in 16. History of allergic manifestations (asthma, rhinitis, eczema, urticaria) was present in the family of 19 patients. Forty-two patients presented with asthma before development of NA and 23 of them were treated with steroids. Nineteen subjects gave a history of desensitization and 5 of vaccination in the 4 weeks preceding the disease. The main symptoms of NA were asthma in 43, fever in 25, weight loss in 31, peripheral neuropathy in 29, cutaneous signs in 25, digestive signs in 16 (abdominal pain, digestive bleeding, bowel perforation), noninfectious pneumopathy with pulmonary infiltrates in 33. Eosinophilia was 8,212 +/- 6,214/mm3. Antigen HBs was found in 2 of 30 patients. Prognosis of NA with asthma was good in 15 patients who recovered completely from the disease. Seven patients died and the other patients improved but remained under treatment. The survival curve showed that 75% of patients were alive after 60 months. Our findings suggest that different causes can be considered responsible for NA, and that, in cases of NA with asthma, there is reason to consider vaccination and desensitization as precipitating factors.

Systemic polyarteritis nodosa diagnosed at hysterectomy.

A 61-year-woman was referred because of declining general health. A diagnosis of uterine malignancy was suspected on the basis of uterine enlargement and an elevated erythrocyte sedimentation rate. Hysterectomy was performed, and histologic examination revealed necrotizing vasculitis affecting the ovaries, fallopian tube, and uterus. Muscle biopsy showed typical periarteritis nodosa lesions. Despite the scarcity of such cases, the incidental finding of necrotizing arteritis in a surgical uterine specimen warrants further investigation to determine if the vasculitic process is localized.

Emergency percutaneous coronary dilatation for acute myocardial infarction in Behçet's disease.

We describe a young man with Behçet's disease who presented with acute coronary insufficiency: emergency coronary arteriography revealed 2 coronary aneurysms and a left anterior descending (LAD) artery stenosis which was successfully dilated. The reduction of the coronary stenosis by balloon angioplasty induced immediate relief of chest pain and decrease of ST segment elevation, and was probably responsible for the satisfactory evolution, with limited myocardial infarction on the ECG and no akinetic segment on the left ventricular angiogram 3 weeks after the acute event. Cardiac surgery was performed to avoid possible relapse or aneurysmal rupture with hemopericardium. Surgery confirmed the destructive arterial lesion of Behçet's disease with false aneurysms of the LAD and left circumflex arteries.
