Abstract
Antiendothelial cell antibodies (AECA) have been detected in 20 out of 30 patients (67%) with thrombosis associated with antiphospholipid antibodies. Seven patients had systemic lupus erythematosus and 13 had the "primary" antiphospholipid syndrome. Seven patients had both IgG and IgM AECA, 9 had IgG AECA only, and 4 had only IgM AECA. None of 30 control patients with thrombotic events not related to antiphospholipid antibodies had a positive titre of AECA (P less than 0.001). No correlation between AECA, antinuclear antibodies, anti-dsDNA antibodies, anti-neutrophil cytoplasm antibodies, precipitating antibodies to soluble nuclear and cytoplasmic antigens or complement components was found. The possible role of these AECA in the pathogenesis of thrombotic events is discussed.

Abstract
Twenty-three patients with the 'primary' antiphospholipid syndrome were studied over 2-6 years. Twenty-two (96%) had antiphospholipid antibodies detected by ELISA (87% had antibodies to thromboplastin and 70% to cardiolipin), and 18 out of the 21 tested patients (86%) had lupus anticoagulant activity by coagulative assays. Mean age of the cohort was 29.9 years and the sex ratio (female:male) 4.75:1. Eleven patients presented 18 venous and/or arterial thrombosis and 13 had 25 foetal losses (84% occurred during the second and third trimester). Other clinical features were migraine, livedo reticularis, and epilepsy. Three patients had relatives with systemic lupus erythematosus. Thrombocytopaenia was seen in 33%, antinuclear antibodies in low or moderate titre in 30%, and haemolytic anaemia in 13%. During the follow-up, two patients presented recurrent thrombosis despite anticoagulant therapy, one of them dying because of recurrent pulmonary thromboembolism. Four patients achieved successful term pregnancies after treatment with aspirin and a further patient after treatment with aspirin and low dose prednisolone. No patient developed systemic lupus erythematosus or any other definable connective tissue disease. The 'primary' antiphospholipid syndrome may exist as a distinct clinical entity and all younger patients presenting with thrombotic events, foetal losses and/or thrombocytopaenia, without any evidence of a well defined disease, should be tested for antiphospholipid antibodies in order to rule out this syndrome.

Abstract
A retrospective study of 25 patients with polymyositis-dermatomyositis (PM-DM) is analyzed with special attention to the effects of therapy and follow-up. All patients (100%) complained of muscle weakness and 68% of these demonstrated typical skin changes of DM. All patients, except 2, received corticosteroids at the onset of the disease, 23 were treated with azathioprine, 7 received cyclophosphamide, 4 methotrexate, and 1 had total body irradiation. Among the patients adequately treated with azathioprine, 75% had a good response, but 5 patients did not improve. Cyclophosphamide was used subsequently in 2, with a satisfactory response in 1. Another patient had a striking response to oral methotrexate, and total body irradiation helped to improve another patient. Although high dose corticosteroids were the preferred starting medication for the treatment of PM-DM, it is important to detect those patients who do not respond adequately and/or develop side effects. In these circumstances, the prompt use of immunosuppressive agents appears justified.

Abstract
A pure sensory neuropathy caused by lymphocytic infiltration of the dorsal root ganglia has been reported in a few patients with Sjögren's syndrome. The clinical, immunological, and electromyographic findings of five patients with this type of neuropathy and primary Sjögren's syndrome were reviewed. Typical clinical indications were the presence of a chronic asymmetrical sensory deficit, initial disease in the hands with a predominant loss of the vibratory and joint position senses, and an association with Adie's pupil syndrome or trigeminal sensory neuropathy. The simultaneous impairment of the central and peripheral evoked cortical potentials suggested that there was a lesion of the neuronal cell body. The neuropathy preceded the diagnosis of Sjögren's syndrome in four patients. Four patients were positive for Ro antibodies, but systemic vasculitis or malignancy was not found after a mean follow up of six years. These findings indicate that in patients with a sensory neuropathy the diagnosis of Sjögren's syndrome has to be considered, even if the patient denies the presence of sicca symptoms, and that appropriate tests must be carried out.

Abstract
IgG and IgM isotypes of anticardiolipin (aCL) antibodies were measured in a group of 40 patients with biopsy-proven temporal arteritis (TA), 13 of them with ischemic complications related to the disease. High levels of aCL antibodies were found in only 3 (7.5%) patients. Two had high titres of both IgG and IgM isotypes and the third had high titres of the IgM isotype. No relationship between aCL antibody positivity and the development of any of the classical early occlusive complications of TA was found. However, 2 out of the 3 patients with positive aCL antibody titres later developed ischemic phenomena on conventional corticosteroid treatment. This finding suggests that aCL antibodies could perhaps have a role in the development of the late ischemic complications that occasionally occur in adequately treated TA patients.

Abstract
A prospective echocardiographic study was carried out on 132 consecutive patients with systemic lupus erythematosus (SLE) derived from three European university medical centres. The prevalence of valvular lesions in patients with SLE was 22.7% compared with 2.9% in a control group of 68 healthy volunteers. 50 SLE patients had antibodies against phospholipids. The prevalence of valve vegetations (8/50 [16%]) and of mitral regurgitation (19/50 [38%]) was significantly higher among the SLE patients with antiphospholipids than among those without (1 and 10/82 [1.2% and 12%], respectively). During follow-up of the patients with valvular lesions, haemodynamically significant clinical valve disease developed in 6 but surgery was required in only 1; 9 had cerebrovascular occlusions; and 7 died, although no death was due directly to the cardiac involvement. Thus, valvular heart disease, particularly affecting the mitral valve, is common in patients with SLE, and the presence of antibodies against phospholipids is associated with a higher prevalence of valvular abnormalities in these patients.

Abstract
A prospective study of IgG and IgM isotypes of anticardiolipin antibodies (aCL) in a series of 100 patients with systemic lupus erythematosus was carried out. To determine the normal range of both isotype titres a group of 100 normal control serum samples was studied and a log-normal distribution of IgG and IgM isotypes was found. The IgG anticardiolipin antibody serum was regarded as positive if a binding index greater than 2.85 (SD 3.77) was detected and a binding index greater than 4.07 (3.90) was defined as positive for IgM anticardiolipin antibody. Twenty four patients were positive for IgG aCL, 20 for IgM aCL, and 36 for IgG or IgM aCL, or both. IgG aCL were found to have a significant association with thrombosis and thrombocytopenia, and IgM aCL with haemolytic anaemia and neutropenia. Specificity and predictive value for these clinical manifestations increased at moderate and high anticardiolipin antibody titres. In addition, a significant association was found between aCL and the presence of lupus anticoagulant. Identification of these differences in the anticardiolipin antibody isotype associations may improve the clinical usefulness of these tests, and this study confirms the good specificity and predictive value of the anticardiolipin antibody titre for these clinical manifestations.

Abstract
Systemic lupus erythematosus developed in a 35-year-old woman who had partial lipodystrophy since she was 7 years old. To our knowledge, this association has been reported only once. She also had hypocomplementemia, mesangiocapillary glomerulonephritis type II, and a serum assay with positive results for C3 nephritic factor. The association of partial lipodystrophy with other autoimmune disorders suggests an immunologic pathogenesis for this disease.

Abstract
We have studied, prospectively, the incidence of several antiphospholipid antibodies (lupus anticoagulant, anticardiolipin, anti-phosphatidylserine, anti-phosphatidic acid, anti-phosphatidylinositol and anti-thromboplastin antibodies) in 65 consecutive patients with two or more (range 2-8, mean 3.1) abortions. Lupus anticoagulant activity was detected in seven (10.7%) patients and all of them exhibited other antiphospholipid antibodies. Of the previous pregnancies in these seven women, 88% had ended in spontaneous abortion. Four of them achieved pregnancy after low-dose aspirin therapy was started, and carried successfully to term. It is concluded that antiphospholipid antibodies, namely lupus anticoagulant, should be routinely screened in the recurrent spontaneous aborter.

Abstract
A prospective study of IgG and IgM isotypes of anticardiolipin antibodies (aCL) was performed in a series of 167 patients with various autoimmune diseases, including rheumatic and nonrheumatic disorders, and in a group of 100 healthy blood donors. The IgG aCL serum was regarded as positive if a binding index (BI) greater than 2.85 (3.77 SD) was detected and a BI greater than 4.07 (3.90 SD) was defined as positive for IgM aCL. Forty patients (24%) were found to be positive for IgG and/or IgM aCL. IgG aCL were detected in 23% of patients with systemic lupus erythematosus (SLE), in 9% with idiopathic thrombocytopenic purpura, in 7% with progressive systemic sclerosis, and in 6% with dermatomyositis-polymyositis. IgM aCL were present in 43% patients with primary biliary cirrhosis, in 33% with rheumatoid arthritis, in 22% with SLE, and in 8% with giant-cell arteritis. IgG aCL were found to have a significant association with thrombosis and thrombocytopenia, and IgM and aCL with haemolytic anaemia and neutropenia, in SLE but not in the other autoimmune diseases. The identification of these differences in the aCL isotype associations, depending on the autoimmune disorder, may improve the clinical usefulness of these tests.

Abstract
In February and March 1989 a community-acquired outbreak of legionnaires' disease developed in Barcelona, involving at least 56 patients (48 males and 8 females) with a mean age of 60 years (range 22-87). 70% were smokers, 20% alcohol abusers, 50% had chronic bronchitis and 20% were immunologically depressed. The most common signs and symptoms were: fever (100%), features of lung condensation (77%), cough (51%), stupor (27%), diarrhea (18%), thoracic pain (18%, hyponatremia (53%), increased serum level of hepatic enzymes (44%) or CK (37%), and renal failure (21%). Radiological involvement was bilateral in 30% of cases. In most patients the diagnosis was made by seroconversion (70%). Late seroconversion (between 4 and 14 weeks) was seen in 20 patients, whose age was significantly higher than that of patients with early seroconversion (p less than 0.02). All cases were caused by Legionella pneumophila serogroup 1. Forty-six patients (81%) were admitted to the hospital and 10 (18%) required tracheal intubation. Although all received erythromycin, seven patients died. Hypoxemia, leukopenia, hyponatremia and renal failure were associated with a higher mortality rate. However, after multivariate analysis renal failure appeared as the only independent prognostic variable. Finally, it was concluded that in the community-acquired outbreaks of pneumonia Legionella pneumophila infection should be ruled out.
