[French register of lupus in pregnancy: the evaluation. Groupe d'étude sur la grossesse lupique].

A register of systemic lupus erythematosus has been open between 1st January 1987 and 31 December 1992 in France. One hundred and seventeen cases of pregnancy from more than 40 centers origin have been prospectively collected. One hundred and three were analyzed. Pregnancy outcome was as following: full term birth (n = 28), premature birth (n = 48), fetal wastage (n = 18 i.e. 13 early spontaneous abortions, two late spontaneous abortions and three stillbirths), therapeutic abortion (n = 5), elective abortion for unwanted pregnancy (n = 4). Four preterm babies died in neo-natal period. Lupus activity was present at pregnancy diagnosis in 28 cases (27%). Of 75 patients with inactive lupus at pregnancy beginning, 27 relapsed during pregnancy and seven in post-partum period. Two patients with nephrotic syndrome died of opportunistic infection. Fetal prognosis is mostly related to proteinuria and absence of anti-SSA antibodies. History of fetal losses, lupus activity at pregnancy beginning, hypertension, use of 20 mg/d or more prednisone dosage during pregnancy influence prematurity. The fetal hypotrophy factors are short duration of pregnancy, lupus activity at beginning of pregnancy, low serum levels of C3 or C4, hypertension, absence of anti-SSA antibodies. Three out of 22 newborns from mother with anti-SSA antibodies developed neonatal lupus: two with cutaneous lupus and one with complete congenital auriculo-ventricular block.

[Lupus bronchiolitis obliterans: diagnostic difficulties].

Bronchiolitis obliterans is exceptional in systemic lupus erythematosus (SLE). Its response to treatment is irregular and prognosis is bad. We report a case of a bronchiolitis obliterans in a 18 year-old woman with a SLE. Oral prednisone, plasmapheresis and cyclophosphamide were unsuccessful. However, only intravenous bolus of methylprednisolone effected improvement.

[Do neuromyosites exist?].

Neuromyositis defined as the association of dermatomyositis or polymyositis and a neuropathy without any found cause is a very controversial entity because of the possibility of, in one hand, muscular modifications caused by neurological involvement and, on the other hand, neurogenic type manifestations caused by polymyositis. The study of 4 cases seen in an Internal Medicine department and the review of the literature allowed us to show that the concept of neuromyositis corresponds to a clinico-pathological reality when the diagnosis is based on the association of definite criteria of both primary muscle and nerve involvement excluding muscular abnormalities that could be the consequence of nerve involvement and vice versa. The criteria, most relevant when associated are: a) for muscular involvement: high increase of muscular enzyme over 6 times the superior limit of the normal values, pseudomyotonic electrical discharges, perifascicular atrophy, intense inflammatory infiltrates and massive necrosis, b) for neurological involvement: early abolition of tendinous reflexes in a patient without notable muscular atrophy and with little or no myalgia, sensitive abnormalities in areas other than those of muscular involvement, especially when they are intense, early weakness of distal muscles, decrease of nerve conduction speed, target fibers and lesions of nerve trunks (and albuminocytological dissociation in the particular case of polyradiculoneuritis). Once the diagnosis of neuropathy settled, it is necessary to exclude an usual cause (alcoholism, diabetes...) before concluding to neuromyositis. When we apply these restrictive (but nevertheless necessary for the validity of diagnosis) criteria, only 6 cases of the literature respond to this entity. It is a peripheral neuropathy in 5 cases (like two of ours) and a polyradiculoneuritis in one case (like our two others). Among these 6 cases, there is a vasculitis in two, frequency much higher to what is observed in adult polymyositis, which suggest a possible causative role of vascular involvement in neuropathy arising. In the other cases we can just give pathogenic hypothesis making the neuropathy and the polymyositis the result of the same process (immunological disturbance, paraneoplastic origin, viral disease). In one of our four patients, who have shown an HTLV-I infection by polymerase chain reaction in situ hybridization was positive in muscle which suggest a direct pathogenic role of the virus. HTLV-I infection should be considered as a possible cause of neuromyositis especially in endemic areas.

Wegener's granulomatosis. Dermatological manifestations in 75 cases with clinicopathologic correlation.

BACKGROUND AND DESIGN: Mucosal and cutaneous manifestations of Wegener's granulomatosis (WG) are usually described separately. Both frequently occur at any time of the illness. The aim of this work was to analyze, retrospectively, dermatologic symptoms of 75 WG cases encountered from 1973 through 1992. All patients fulfilled the American College of Rheumatology criteria for WG. We compared clinical and histologic findings and looked for a relationship between these manifestations, disease activity, and other symptoms of WG. RESULTS: Thirty-five patients had skin or mucosa involvement. Clinical features were palpable purpura (26 cases), oral ulcers (15), skin nodules (six), skin ulcers (five), necrotic papules (five), gingival hyperplasia (three), pustules (two), palpebral xanthoma (two), genital ulcer (one), digital necrosis (one), and livedo reticularis (one). Pathologic findings depended on clinical aspects. Thirty-five involved skin or mucosa biopsy specimens were obtained from 24 patients. Nongranulomatous vasculitis was associated with purpuric lesions. Granulomatous inflammation was associated with nonpurpuric lesions. Dermatologic manifestations were associated with a higher frequency of articular and renal involvement (68% vs 25%; 80% vs 47%, respectively). Except for xanthoma, onset of skin or mucosa lesions indicated active systemic disease. These manifestations responded well to steroids and cyclophosphamide. CONCLUSIONS: Various dermatologic manifestations are frequently observed in WG. They have distinctive pathologic features and usually indicate the presence of active systemic disease, especially with kidney and joint involvement.

[Intra-alveolar hemorrhage in Wegener's granulomatosis. Retrospective study of 9 cases].

Among 66 patients with Wegener's granulomatosis, 9 had an intra-alveolar haemorrhage which revealed the disease. The diagnosis was based on dyspnoea (n = 9), haemoptysis (n = 9) and anaemia (n = 9) with a mean haemoglobin level of 8 +/- 1 g/dl. Radiology showed bilateral alveolar infiltrates (n = 9), and numerous siderophages were found either in the alveolar lavage fluid (n = 7/7) or in sputum (n = 2). In every case, the alveolar haemorrhage was accompanied by a rapidly progressive extracapillary glomerulonephritis and by lesions of the upper airways which preceded it by several months or years. All patients received corticosteroids combined, in 8 cases, with cyclophosphamide. The respiratory disease improved rapidly, in contrast with the renal disease which became worse (n = 5). Two patients died in the acute phase of the vasculitis: one of acute renal failure, the other of infectious shock.

[Changes in the diastolic left ventricular function in primary antiphospholipid antibody syndrome].

Previous studies have shown that left ventricular (LV) diastolic function is frequently impaired in patients with systemic lupus erythematosus. We prospectively studied echo-Doppler indices of LV diastolic function in 18 patients with primary antiphospholipid syndrome (PAPS), who where compared to a group of 18 healthy controls. Heretofore undescribed LV relaxation abnormalities were found in the PAPS group: this finding suggests the existence of a causal link.

[Long-term prognosis of arterial lesions of Behçet's disease].

We analyzed the charts of 25 patients with arterial lesion in Behçet's disease with mean follow-up 76 months. We conclude that prognosis is poor. Corticosteroids and surgery if possible is needed, anti-aggregant or anticoagulants and prosthetic rather than venous graft are suitable. This therapy does not exclude the risk of relapse. Immunosuppressive drugs in addition to corticosteroids seem to be more efficient than corticosteroids alone but the therapeutic modalities need to be define.

[Malacoplakia. Apropos of a case of retroperitoneal site].

Malacoplakia is a granulomatous inflammatory disease caused by a disorder of macrophage bactericidal function. The disease, histologically characterized by the presence of Michaelis-Gutmann bodies, has a preference for the urogenital tract and less frequently affects the gastrointestinal tract and the retroperitoneal region. We report the unusual case of a male patient who presented with retroperitoneal pseudotumoral malacoplakia associated with vesical malacoplakia. The main pathophysiological, diagnostic and therapeutic aspects of this rare disease are described.

[What criteria for the diagnosis of antiphospholipid syndrome?].

The "historical" definition of the antiphospholipid syndrome is the most widely used: history of at least one venous and/or arterial thrombosis and/or two miscarriages, and positive tests for lupus anticoagulant and/or anticardiolipin antibodies, on two occasions more than 8 weeks apart. More recently, a Mexican group proposed another definition taking into account the number of clinical manifestations and the titer of anticardiolipin antibodies to categorize patients as definite, probable or doubtful antiphospholipid syndrome. The respective merits and limitations of both definitions are discussed.

[Sarcoidosis in a cicatrix: apropos of 5 cases].

The authors report 5 cases of sarcoidosis developed on scars. Sarcoidosis may be isolated (1 case); it may precede (1 case) or accompany systemic sarcoidosis, or occur during a relapse (3 cases). Dermatologists who observe cicatricial changes always suspect sarcoidosis. It is therefore important that physicians should examine the scars of their patients with suspected sarcoidosis, since biopsy of these scars is easily performed, confirms the diagnosis and avoids more invasive explorations.

[Relapsing polychondritis and mesenteric panniculitis: apropos of 2 cases].

We report two cases of polychondritis associated with mesenteric panniculitis. Case 1. In February 1989, a woman born in 1949 presented with 40 degrees C fever accompanied by pain in the abdomen and pelvis. Eight days later, nodular skin lesions appeared on her lower limbs. The abdomen was swollen with gas and undepressible. An abdominal CT scan revealed partitioned peritoneal collections, and a guided needle aspiration produced a chylous fluid. Direct and indirect bacteriological examinations gave negative results. Histology showed intense inflammatory reaction with giant cells and lipophages, thereby confirming the presence of mesenteric panniculitis. Six months later, the development of chondritic lesions on the nose and the helix of the ear clinched the diagnosis of polychondritis. The patient was put on corticosteroid therapy for a few months, and in January this year (1993) she is durably asymptomatic. Case 2. In October 1977, a woman born in 1937 presented with polychondritis with prolonged fever, inflammatory syndrome and chondritic lesions of the nose, larynx and helix of the ear. In December 1978, she developed signs of abdominal obstruction. Laparotomy revealed infiltration by multiple nodular formations of the entire posterior line of attachment of the mesentery. Biopsies withdrew a puriform fluid. Histology showed a partly necrotic adipose tissue with giant cells and lipophages. High-dose corticosteroid therapy partially controlled the chondritic and abdominal manifestations. The occurrence of abdominal pain in patients with polychondritis may result from several disorders, such as iatrogenic complications, digestive tract vasculitis or ulcerative colitis, but also associated mesenteric panniculitis.

MRI in 31 patients with Behçet's disease and neurological involvement: prospective study with clinical correlation.

Thirty one patients with Behçet's disease and neurological manifestations were prospectively studied with MRI. Cerebral venous thrombosis was diagnosed in 10 patients. MRI performed during the acute illness in eight patients showed an abnormally high signal on the T2 weighted sequences in the occluded sinus. MRI showed minor flow abnormalities suggestive of partial recanalisation of the sinus in two cases at a later clinical stage. MRI can be an alternative, non-invasive, investigation to intravenous cerebral angiography. In 13 patients with central nervous system involvement, MRI performed during the acute illness showed multiple hyperintense lesions on T2 weighted sequences. They were usually less than 5 mm, scattered and confluent, mainly in the white matter, distributed in the hemispheric white matter in nine cases, brainstem in eight, basal ganglia and thalamus in five, and cortex in two. MRI abnormalities were usually associated with appropriate clinical deficits, but were larger and more disseminated than expected.
