Abstract
The pregnancies of ten women, all with histories of at least two spontaneous abortions of unknown cause, were followed. All patients were positive for immunoglobulin (Ig) G anticardiolipin antibodies (aCL) and one also for IgM aCL, while none had lupus anticoagulant activity. During pregnancy, the patients were treated with calcium heparin in doses varying between 15,000 and 30,000 IU daily. IgG aCL were assayed on average at the 9th, 17th, 24th and 29th weeks of pregnancy and at the moment of delivery. Mean values of IgG aCL levels during the 10 pregnancies steadily fell as the pregnancies progressed, and this decrease was significant (r = 0.985, P = 0.002). All pregnancies terminated favourably, although delivery was brought forward in eight patients and six of the nine placentas examined showed signs of thrombotic events. We assume that a steady fall in IgG aCL levels during pregnancy may be considered as indicative of a favourable outcome.

Abstract
Using different monoclonal antibodies, we performed an immunofluorescent technique on labial salivary glands in order to investigate the immunological phenomena involved in Sjögren's syndrome (SS). An aberrant expression of HLA-DR molecules was detected on cytoplasm of epithelial labial salivary cells in 9 out of 19 (47%) patients, with SS. No such expression was found in 8 patients without SS or in 3 normal controls. HLA-DQ molecules were demonstrated also in two out of ten SS patients without HLA-DR. A lymphocytic infiltration was not correlated with the expression of class II molecules. T cells bearing gamma delta receptors were not detected. The intracellular adhesion molecules (ICAM-1) and lymphocyte function associated antigen-1 (LFA-1) were not found on epithelial glandular salivary cells of patients and controls. In conclusion, these data suggested that the absence of ICAM-1 and LFA-1 in salivary cells and the absence of infiltrating T cells bearing gamma delta receptors exclude their immunopathogenetic role in SS; moreover, these data demonstrated that the aberrant expression of HLA class II molecules on epithelial salivary cells of patients with SS is not a phenomenon correlated with the lymphocytic infiltration.

Abstract
Anticardiolipin antibodies (aCL) of immunoglobulin (Ig) G and M classes were determined in 28 patients affected with chronic discoid lupus erythematosus (CDLE), comparing their prevalence and levels to those in 60 healthy subjects matched for age and sex. A high and significant frequency of IgG (67.8%) and IgM (50.0%) aCL together with prevalence of high antibody levels was found in CDLE patients, while healthy controls had IgG and IgM aCL in 1.6% and 3.3% of cases respectively. Clinical features in keeping with the diagnosis of antiphospholipid syndrome were found in one patient (3.5%), which, as the first manifestation of the syndrome, showed a pulmonary thromboembolism which appeared some days after prolonged exposure to the sun. These results provide additional data on autoimmune phenomena in CDLE and suggest that aCL test should be considered as useful aids in immunological diagnosis of CDLE.

Abstract
Various sets of criteria have been suggested in order to establish a diagnosis of Sjögren's syndrome (SS) in as much as evaluation of the salivary component is highly controversial. Our study was aimed at investigating both sensitivity and specificity of labial salivary gland biopsy (LSGB), as well as at comparing this method with other diagnostic procedures commonly employed in SS. LSGB was performed in 182 patients (174 female and 8 male, mean age 51.2) with xerostomia, dry eyes, parotid swelling and/or serological abnormalities such as positive rheumatoid factors, antinuclear antibodies, leukopenia and hypergammaglobulinemia. Diagnosis of SS was made according to the criteria recently proposed by Vitali et al. (1993). Severity of histologic changes was graded according to the Chisholm and Mason scoring system. Bioptic samples were considered abnormal when at least one focus of mononuclear cells/4mm2 was observed. The following parameters were also assessed in each patient: questionnaire of symptoms, Saxon test, sialography, salivary dynamic scintiscan, Schirmer-I-test, rose Bengal score, ANA, anti-SSA/SSB antibodies and rheumatoid factors. According to the above diagnostic criteria, 108 out of 182 patients had SS, 90 primary and 18 secondary. For 74 there were not enough data for a definite diagnosis of SS. In 9 cases (4 with and 5 without SS) LSGB was excluded because no glandular tissue was found in the specimens. Among the remaining 173, Grades 3 or 4 were found in 74 patients (71.2%) with SS and only in 1 case (1.4%) without SS. LSGB showed a very high specificity (98.6%) and a rather good sensitivity (72.5%). However, biopsy was crucial for diagnosis in only 11 cases (14.6%).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We describe a 24 year old female patient affected with symptoms of severe xerostomia and keratoconjunctivitis sicca since her childhood. She also had several malformations involving face and digits as well as cup shaped ears, enamel dysplasia and absence of lacrimal puncta. Hence, the diagnosis of Lacrimo-Auricolo-Dento-Digital (LADD) syndrome was made. The main differences between this rare, inherited disease and primary juvenile Sjögren's syndrome are pointed out.

Abstract
We describe a 41-year-old woman, in whom antiphospholipid antibody syndrome (APS) occurred at presentation, before the detection of an ovarian endometrial adenocarcinoma. This syndrome was characterized by widespread and worsening thromboembolism and it did not respond to conventional anticoagulant treatment. The paraneoplastic nature of this APS was strongly suggested by the disappearance of both thromboembolism and antiphospholipid antibodies only after surgical removal of the cancer.

Abstract
The objective of this study was to verify the accuracy of ultrasonography in assessing the topography, morphology, and extent of synovial proliferation in rheumatoid and psoriatic knee joint synovitis. Findings were compared to those obtained using prospective arthroscopy as the gold standard; in addition, topographically defined sonographic findings before and after arthroscopic synovectomy were compared. Sonographic examination was performed in 12 patients with rheumatoid arthritis (13 knees) and 13 patients with psoriatic arthritis (14 knees) who had synovitis of the knee using an electronic linear transducer (7.5 MHz) or a mechanical sector transducer (10 MHz). This examination was followed within 1 week by arthroscopy, to compare the topography (intra-articular localization) and the morphology (sonographic patterns) of synovial proliferation. In 15 knees undergoing arthroscopic synovectomy, preoperative sonographic measurement of synovial thickness in the suprapatellar, medial parapatellar, and lateral parapatellar recesses was compared with arthroscopic visualization of synovial proliferation; 13 knees were reevaluated 2 months after arthroscopic synovectomy by sonography at the same sites. Three distinct sonographic patterns of synovial proliferation were confirmed by arthroscopic examination: a villonodular aspect in 12 knees; uniform thickening in eight knees, and overlapping layers in seven knees. About 50% of the knees showed more than one sonographic pattern, with no differences in pattern distribution between rheumatoid arthritis and psoriatic arthritis patients. A significant correlation was found between sonographic and arthroscopic evaluations of synovial thickness in the suprapatellar (P < 0.02) and medial parapateoffr recesses (P < 0.02), the sites of maximal synovial proliferation in our patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case of scapular Paget's disease of bone with concurrent autoimmune thyroiditis and articular chondrocalcinosis is reported. Although infrequent, this combination suggests the involvement of common pathogenic mechanisms: thyroiditis and Paget's disease may stem from the same viral infection and/or autoimmune disorder, whereas chondrocalcinosis may be the consequence of thyroiditis-related hypothyroidism. In contrast, the association of Paget's disease and chondrocalcinosis may be fortuitous, since both disorders are common.

Abstract
High levels of many cytokines, including interleukin (IL)-1, IL-6 and IL-8, were found in various arthropathies suggesting that they play a role in the pathogenesis of disease, although their relationship with the type and activity of disease is still not clear. The synovial fluid (SF) of 24 patients with rheumatoid arthritis (RA), 19 with psoriatic arthritis (PA) and 33 with osteoarthritis (OA) was analyzed for IL-1 beta, IL-6 and IL-8. The highest concentration of the three cytokines was found in the SF of RA. IL-beta detectable levels (> or = 20 pg/ml) were observed in 8/24 (33.3%) patients with RA, in one patient with PA but in no patient with OA. IL-6 (mean +/- SD) (1610.37 +/- 1781.65 pg/ml) was higher in RA than in PA (672.47 +/- 867.40 pg/ml, p = 0.043) and OA (89.45 +/- 120.52 pg/ml, p = 0.0001). IL-8 (1042.72 +/- 698.64 pg/ml) was higher in RA than in PA (660.36 +/- 625.11 pg/ml, p = 0.03) and OA (89.9 +/- 45.88 pg/ml, p = 0.0001). A correlation between IL-1 beta, IL-6 and IL-8 was found in RA. In all patients a correlation between IL-6 and IL-8 levels was found; moreover, these two cytokines were associated with SF indices of inflammation, such as white blood cells (WBC) count and total protein (TP) concentration. Our findings suggest that these interrelationships play a role in the evolution of more severe erosive arthropathy such as RA.

Abstract
We report the clinical observation of a 23-year-old woman affected by the so-called 'catastrophic antiphospholipid syndrome'. Within a 3-month period she suffered a number of thrombotic events and haemolytic anaemia with thrombocytopenia and had high levels of immunoglobulins G and M and anticardiolipin antibodies associated with lupus anticoagulant activity. The severity of the clinical and laboratory changes is described and diagnostic and therapeutic difficulties are discussed. The apparent control of thrombotic events only with high levels of warfarin anticoagulation is stressed.

Abstract
OBJECTIVES The differential expression of several accessory/activation molecules (CD26, CD29, CD45RA, CD25, MLR4, HLA-DR) on peripheral blood CD4+ and CD8+ T lymphocytes in patients with scleroderma was compared with that in controls and patients with other connective systemic diseases to look for evidence of the involvement of T cells in the disease process of scleroderma. METHODS The two colour expression of surface molecules by circulating T cells was analysed with a panel of monoclonal antibodies and flow cytometry in 17 patients with scleroderma, 10 patients with systemic lupus erythematosus, and five patients with rheumatoid arthritis, and the results compared with those for 10 normal controls. The two colour T CD4+ phenotype was further compared between patients with active and quiescent disease in these patients with scleroderma. The coexpression of surface molecules by CD4+ T cells was also analysed by three colour flow cytometry in eight patients with scleroderma. RESULTS Patients with scleroderma showed increased CD4+CD26+ and CD4+CD25+ percentages and absolute numbers and decreased CD8+CD29+ percentages compared with controls. Moreover, a significant correlation between the higher CD4+CD26+ T cell percentage and absolute cell numbers with disease activity was observed. Most of the CD4+ peripheral blood T cells from patients with scleroderma showed the CD26+CD45RA- phenotype by three colour flow cytometry analysis. CONCLUSIONS The distinctive pattern of early helper memory T cell activation in these patients with rapidly evolving scleroderma supports the role of a T cell mediated mechanism in the progression of scleroderma.

Abstract
OBJECTIVE To test synovial fluid (SF) for the presence of soluble fragments originating from distinct tumor necrosis factor receptors (TNF-sR55 and TNF-sR75) which bind to TNF and inhibit its biologic activity. METHODS TNF-sR55 and TNF-sR75 were measured in 62 SF samples by specific immunoassays using monoclonal antibodies. RESULTS Both TNF-sR were present in all of the SF tested. Their concentrations were higher in SF from patients with seropositive rheumatoid arthritis than in patients with other inflammatory arthritides. The relative amount of TNF-sR75, as compared with TNF-sR55, was higher in seropositive RA SF than in other SF. CONCLUSION The balance between TNF and its specific inhibitors may be critical to the biologic outcome mediated by this cytokine.

Abstract
To investigate the possible immunomodulatory mechanism of D-penicillamine in Scleroderma (Scl), we analysed the surface phenotype of circulating T lymphocytes in 17 Scl patients, 6 of these studied before and after D-penicillamine treatment, 8 only before and 3 only after treatment. The drug was administered for 6 to 24 consecutive months with a median daily dose of 500 mg. The study of peripheral blood purified T cells was carried out using single-colour immunofluorescence and flow cytometry analysis (Ortho Diagnostic System) with monoclonal antibodies such as OKT4 (CD4, helper/inducer), OKT8 (CD8, cytotoxic/suppressor), OKDR and MLR4 (activated T cells), and Tec-5/9 (CD26, activated T cells with specific helper function for B cell differentiation). All of the patients showed lower CD8+ and higher MLR4+ and DR+ T cells than the controls, while CD26+ and CD4+ circulating T lymphocytes were lower in all of the treated in comparison with all of the untreated patients. A decrease in CD26+, CD4+ and total T cells was also observed after treatment in the 6 patients studied pre- and post-therapy. These results support the hypothesis that D-penicillamine selectively impairs the helper T cell subset in Scl patients.

Abstract
Rheumatoid arthritis presents with different clinical manifestations according to the age of onset. The authors have studied the involvement of the lacrimal function in two different cohorts of patients, 70 adult-onset (onset of the disease between 15 and 60 years of age) and 30 old-onset (60-79 years), as compared to two groups of normal controls of the same age. Schirmer I, Break-Up Time (BUT), and Bengal rose were tested. Senile rheumatoid arthritis (SRA) not only did not show more severe lacrimal changes when compared to adult rheumatoid arthritis (ARA) of the same duration, but failed to show statistical differences in tear secretion when compared to a healthy population of the same age. ARA patients showed a significant tear deficiency when compared to a healthy population of the same age. Within this cohort of patients, 'long-lasting' ARA showed more severe changes when compared to 'short-lasting' ARA. These results would suggest that the involvement of the lacrimal system is more important when rheumatoid arthritis develops in adult rather than in old age, being a function of the duration rather than of the severity of the disease.

Abstract
Two cases of recurrent monoarthritis are described in which antithyroid microsomal (antiMi) autoantibody (Ab) was found in synovial fluid (SF) before any clinical or serological evidence of thyroid disease. Subsequently, the follow-up of the two patients showed the appearance of thyroiditis within 2-5 years. The presence of anti-Mi Ab in SF might anticipate the appearance of autoimmune thyroiditis even in the absence of serum detectable antithyroid Ab, as was later observed in these two cases.

Abstract
A study of esophageal symptoms and function was performed in 21 patients with mixed connective tissue disease (MCTD). Esophageal involvement was found in 18 cases (85%), in 14 (66%) with typical symptoms, in 15 (71%) with manometric abnormalities and in 11 (57%) with both. The manometric pattern was characterized by reduction of amplitude and coordination of peristaltic waves throughout the esophageal body and reduction of lower esophageal sphincter (LES) competency. In comparison, 38 patients with systemic sclerosis showed a similar but more severe pattern, particularly at the level of the distal esophagus and LES. Thus, although similar, the esophageal involvement in MCTD was not exactly the same as that of systemic sclerosis. Furthermore, in MCTD a correlation between manometric abnormalities and cutaneous involvement was lacking, and this suggests that esophageal disorders are not always linked with clinically evident scleroderma-like features of this disease. Since the diagnosis of MCTD is made in the presence of the clinical picture of more than one connective tissue disease, the detection of esophageal involvement by a sensitive technique such as esophageal manometry in a patient with suspected MCTD may be a useful diagnostic aid.

Using unfixed rat liver sections as substrate for the detection of antinuclear antibodies, distinct nuclear staining was observed in the sera of patients with systemic sclerosis. Its reaction differed from previously described fluorescence patterns and was characterized by numerous fine speckles throughout the nucleus associated with one or more coarse lines. These lines were more evident in diluted sera, when fine speckled fluorescence faded. This picture "fine speckles with lines" (FLS) was defined. The FLS pattern was present in 35% of 91 patients with systemic sclerosis, while it was absent in 517 patients with rheumatic and non-rheumatic disorders and in 100 matched healthy subjects. Moreover, the FSL pattern was significantly associated with the diffuse subset of systemic sclerosis (50% of cases) and was related to the presence of anti-Scl-70 antibody. These results indicate that this fluorescent pattern of antinuclear antibodies may be considered a simple and very useful aid in the diagnosis and prognosis of systemic sclerosis.

Abstract
In 6 healthy subjects submitted to fango therapy in the Euganean thermal baths (Italy), the plasma concentrations of beta-endorphin and ACTH increased transitorily but significantly. These results correlate with the release of these peptides by the pituitary in response to thermal stressing. The analgesic and hypothermic action responsible for good toleration of thermal stress induced by fango therapy, can be explained by this increase in plasma beta-endorphin. The repeated brief increases in plasma beta-endorphin during thermal treatment result in progressive improvement in articular and muscular symptomatology. The results of our study on plasma levels of ACTH confirm that the thermal stress associated with fango therapy activates the pituitary gland. Immunomodulatory effects are discussed.
