Abstract
The EULAR Sjögren's syndrome (SS) disease activity index (ESSDAI) is a systemic disease activity index that was designed to measure disease activity in patients with primary SS. With the growing use of the ESSDAI, some domains appear to be more challenging to rate than others. The ESSDAI is now in use as a gold standard to measure disease activity in clinical studies, and as an outcome measure, even a primary outcome measure, in current randomised clinical trials. Therefore, ensuring an accurate and reproducible rating of each domain, by providing a more detailed definition of each domain, has emerged as an urgent need. The purpose of the present article is to provide a user guide for the ESSDAI. This guide provides definitions and precisions on the rating of each domain. It also includes some minor improvement of the score to integrate advance in knowledge of disease manifestations. This user guide may help clinicians to use the ESSDAI, and increase the reliability of rating and consequently of the ability to detect true changes over time. This better appraisal of ESSDAI items, along with the recent definition of disease activity levels and minimal clinically important change, will improve the assessment of patients with primary SS and facilitate the demonstration of effectiveness of treatment for patients with primary SS.

Abstract
INTRODUCTION Nailfold videocapillaroscopy (NVC) in systemic sclerosis (SSc) is a procedure commonly used for patient classification and subsetting, but not to define disease activity (DA). This study aimed to evaluate whether the number of micro-haemorrhages (MHE), micro-thrombosis (MT), giant capillaries (GC), and normal/dilated capillaries (Cs) in NVC could predict DA in SSc. METHODS Eight-finger NVC was performed in 107 patients with SSc, and the total number of MHE/MT, GC, and the mean number of Cs were counted and defined as number of micro-haemorrhages (NEMO), GC and Cs scores, respectively. The European Scleroderma Study Group (ESSG) index constituted the gold standard for DA assessment, and scores ≥ 3.5 and = 3 were considered indicative of high and moderate activity, respectively. RESULTS NEMO and GC scores were positively correlated with ESSG index (R = 0.65, P < 0.0001, and R = 0.47, P <0.0001, respectively), whilst Cs score showed a negative correlation with that DA index (R = -0.30, P <0.001). The area under the curve (AUC) of receiver operating characteristic plots, obtained by NEMO score sensitivity and specificity values in classifying patients with ESSG index ≥ 3.5, was significantly higher than the corresponding AUC derived from either GC or Cs scores (P <0.03 and P <0.0006, respectively). A modified score, defined by the presence of a given number of MHE/MT and GC, had a good performance in classifying active patients (ESSG index ≥ 3, sensitivity 95.1%, specificity 84.8%, accuracy 88.7%). CONCLUSIONS MHE/MT and GC appear to be good indicators of DA in SSc, and enhances the role of NVC as an easy technique to identify active patients.

Abstract
A new approach for the classification of patients with Sjögren's syndrome (SS) has been recently proposed. Although these new criteria substantially differ from the American European Consensus Group criteria, which have represented the gold standard for the last decade, when compared with each other the two sets show a high statistical degree of agreement. However, the fact that two different criteria to classify patient with SS could be available may introduce some additional difficulties in the scientific communication, making cohorts of patients selected by using different methods less than completely equivalent, and the results of epidemiological studies and therapeutic trials not entirely comparable. Consequently, to reach a consensus agreement on universally accepted classification criteria for SS seems to be a very desirable objective.

Abstract
OBJECTIVES The minor salivary gland biopsy (MSGB) is widely considered an important component of the diagnostic algorithm of primary Sjögren's syndrome (pSS) and is mentioned in all the classification criteria sets for the disease. The aim of this study, coordinated by the Italian Society of Rheumatology, was to verify the inter-observer agreement on the evaluation of MSGB among different experienced Italian rheumatologic centres, in order to better standardise the diagnostic methodology. METHODS Seven centres participated in the study, providing a total of 50 MSGB samples. Each center blindly classified all the samples according to the Chisholm and Mason (CM) grading. The results were collected and analysed. RESULTS The inter-observer agreement was satisfactory when the samples were stratified as consistent and non-consistent with the final diagnosis of pSS (median κ =0.75; mean κ =0.70). Nonetheless, significant discrepancies in the histopathologic evaluation of MSGB emerged when the agreement was assessed on the single scores. Considering the modal CM grading for each sample as the correct grading, upon re-examination, a potential bias in the final clinical diagnosis was detected in 7 out of 50 samples. CONCLUSIONS This study has shown significant discrepancies in the evaluation of MSGB among different rheumatologic centres in the same country. Greater standardisation of the procedure is clearly necessary, both to improve the diagnostic performance and scientific communication.

Abstract
Sjögren's syndrome (SS) is a systemic autoimmune disease that affects the exocrine glands, mainly the salivary and lachrymal glands, with consequent persistent dryness of the mouth and eyes. In addition to the clinical manifestations related to the exocrine gland involvement, a consistent prevalence of patients may present systemic manifestations. Some of these can be ascribed to the periepithelial extension of lymphocytic infiltration whilst others are determined by an immunomediated process affecting small- or medium-size vessels. While the use of tear and saliva substitutes and local or systemic stimulation of residual secretions represent the mainstays of the therapy of sicca component, different immunomodulating or immunosuppressive agents are usually required to treat extraglandular features, similarly to what happens in other connective tissue diseases. In the last few years, the advancement in the understanding the pathogenetic mechanisms of this disorder and the availability of new biologic target therapies seem to offer completely new therapeutic options. The use of B cell depleting or modulating therapies has achieved promising results.

Abstract
A clinical picture of dry eye and dry mouth with the histological counterpart of focal lymphocytic sialoadenitis, usually detected in minor salivary glands, is considered the hallmark of Sjögren's syndrome. The association of sicca complaints and focal sialoadenitis can be also found in a number of other diseases, including some systemic viral infections. Among these conditions, chronic hepatitis C virus infection, associated with mixed cryoglobulinaemia and extra-hepatic manifestations, and HIV infection, particularly in the phase of diffuse interstitial lymphocytic infiltration, may mimic the clinical and histological aspects of Sjögren's syndrome. However, each disorder is characterised by specific, disease-related immunopathological aspects. Besides sicca complaints, the various disorders may also share a number of systemic extra-glandular features and the possible development of mucosa-associated lymphoid tissue lymphomas. This latter event represents in all of these diseases the final result of an antigen-driven chronic stimulation of B lymphocytes.

Abstract
OBJECTIVES To develop a score for assessment of patients' symptoms in primary Sjögren's syndrome (SS): the EULAR SS Patient Reported Index (ESSPRI). METHODS Dryness, pain, somatic and mental fatigue were identified as the main symptoms of patients with primary SS, in studies developing the Profile of Fatigue and Discomfort (PROFAD) and Sicca Symptoms Inventory (SSI). It was suspected that a single 0-10 numerical scale for each domain was sufficient to assess these symptoms. These four scales were gathered to form the ESSPRI. 230 patients, from 12 countries completed the ESSPRI, SSI and PROFAD questionnaires and a 0-10 patient global assessment (PGA). Correlations between each symptom and PGA were obtained. Multiple regression modelling, using PGA as 'gold standard' was used to select domains and estimate their weights. RESULTS PGA had good correlation with dryness, limb pain, fatigue and mental fatigue (r=0.49-0.59, all p<0.0001), but correlated less well with individual dryness features. In multivariate analysis, dryness, limb pain and fatigue, but not mental fatigue, were significantly associated with PGA; weights derived from the regression were identical for these three domains. Thus, ESSPRI was redefined as the mean of the three scales: dryness, limb pain and fatigue. Lastly, ESSPRI significantly correlated with PGA (r=0.70), PROFAD (r=0.73) and SSI (r=0.66). CONCLUSION ESSPRI is a very simple index designed to measure patients' symptoms in primary SS. It has good construct validity and is well correlated with SSI and PROFAD. ESSPRI should now be validated for use as an outcome measure in clinical trials.

Abstract
OBJECTIVE Patients with systemic sclerosis (SSc) have significantly fewer and functionally impaired endothelial progenitor cells (EPC) in peripheral blood and bone marrow; further, endothelial apoptosis seems to play a primary role in the pathogenesis of vascular damage. We investigated whether the failure of bone marrow EPC is related to their apoptotic phenotype and analyzed the possible mechanisms inducing apoptosis. METHODS The presence of apoptotic cells was investigated in bone marrow aspirates taken from patients with SSc; microvessel density (MVD) and the immunohistochemical expression of vascular endothelial growth factor (VEGF) were also measured in bone marrow biopsies. A correlation between EPC apoptosis and the presence of antiendothelial cell antibodies (AECA) was also investigated. RESULTS We confirmed the presence of bone marrow EPC dysfunction in SSc, while hematopoiesis was not impaired. Bone marrow studies showed a high percentage of apoptotic progenitors, no signs of fibrosis or an altered MVD, and an increased VEGF index. The patients' bone marrow plasma showed significant titers of AECA, and their presence correlated with that of apoptotic progenitors. These findings were further confirmed by an in vitro assay in which the apoptosis of normal progenitors was induced by the addition of AECA+ purified IgG. CONCLUSION Our results showed that apoptosis in patients with SSc involves the source compartment of endothelial progenitors and correlates with AECA activity. These findings support the hypothesis that AECA may play a pathogenetic role by affecting the bone marrow EPC machinery that should repair the peripheral vascular lesions.

Abstract
OBJECTIVE To develop a disease activity index for patients with primary Sjögren's syndrome (SS): the European League Against Rheumatism (EULAR) Sjögren's syndrome disease activity index (ESSDAI). METHODS Thirty-nine SS experts participated in an international collaboration, promoted by EULAR, to develop the ESSDAI. Experts identified 12 organ-specific 'domains' contributing to disease activity. For each domain, features of disease activity were classified in three or four levels according to their severity. Data abstracted from 96 patients with systemic complications of primary SS were used to generate 702 realistic vignettes for which all possible systemic complications were represented. Using the 0-10 physician global assessment (PhGA) scale, each expert scored the disease activity of five patient profiles and 20 realistic vignettes. Multiple regression modelling, with PhGA used as the dependent variable, was used to estimate the weight of each domain. RESULTS All 12 domains were significantly associated with disease activity in the multivariate model, domain weights ranged from 1 to 6. The ESSDAI scores varied from 2 to 47 and were significantly correlated with PhGA for both real patient profiles and realistic vignettes (r=0.61 and r=0.58, respectively, p<0.001). Compared with 57 (59.4%) of the real patient profiles, 468 (66.7%) of the realistic vignettes were considered likely or very likely to be true. CONCLUSIONS The ESSDAI is a clinical index designed to measure disease activity in patients with primary SS. Once validated, such a standardised evaluation of primary SS should facilitate clinical research and be helpful as an outcome measure in clinical trials.

Abstract
OBJECTIVE To assess and compare the sensitivity to change of the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI) with that of other primary Sjögren's syndrome (SS) disease activity indexes. METHODS We abstracted 96 patient profiles, including data on 3 successive visits (visits 1-3), from the medical charts of patients with primary SS. Patient profiles were scored with the ESSDAI, SS Disease Activity Index (SSDAI), and Sjögren's Systemic Clinical Activity Index (SCAI). Thirty-nine experts assessed 5 profiles for whether disease activity had improved, worsened, or remained stable at visits 2 and 3. RESULTS For improved patients, the standardized response means (SRMs) for all scores did not differ, and ranged from -1.08 to -1.38 between visits 1 and 2 and from -0.50 to -0.76 between visits 2 and 3. For patients with worsened activity, the SRMs between visits 1 and 2 and between visits 2 and 3 were +0.46 and +1.10 for the ESSDAI, -0.03 and +0.79 for the SSDAI, and +0.17 and +1.02 for the SCAI, respectively. For patients with stable activity, the SRMs between visits 1 and 2 and between visits 2 and 3 were 0.00 and -0.13 for the ESSDAI, -0.44 and -0.11 for the SSDAI, and -0.36 and +0.34 for the SCAI, respectively. CONCLUSION For patients with improved activity, the 3 disease activity indexes showed similar, large sensitivity to change. However, the ESSDAI seemed to detect changes in activity more accurately than other disease activity indexes. Notably, for patients with stable activity, the ESSDAI did not show erroneous improvement.

Abstract
Sjögren's syndrome (SS) is a systemic autoimmune disease that is characterized by an aggressive autoimmune response to epithelia, with consequent reduction of their secretions accompanied by sicca complaints. Systemic features may also be present in a subset of patients and may require more aggressive therapies. Improvements in knowledge concerning disease pathophysiology, combined with the availability of specifically targeted therapies able to modulate or block some of the most important pathologic mechanisms of the disease, may open totally new perspectives in the therapeutic approach to SS. The absence of reliable and validated outcome measures for SS is a major obstacle in performing clinical trials of new therapies in SS but studies devoted to defining outcome measurement instruments for this disorder have been performed or are in an advanced phases of completion.

Abstract
OBJECTIVE To investigate whether statins may improve endothelial function in systemic sclerosis (SSc) by evaluating the effects of simvastatin on vasculogenesis [indicated by the expansion of circulating endothelial progenitor cells (EPC)] and the markers of vascular injury in the peripheral blood of patients with SSc. METHODS Twenty SSc patients with normal cholesterol concentrations and 20 hypercholesterolemic subjects were allocated to receive 20 mg/day simvastatin for 12 weeks. Peripheral blood samples were collected before and 12 weeks after initiation of treatment, and 4 weeks after discontinuation. Five-parameter, 3-color flow cytometry was performed with a FacScan to enumerate EPC and mature circulating endothelial cells (CEC). Levels of soluble E-selectin, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, interleukin 6, and endothelin-1 were assessed by commercial ELISA. RESULTS Simvastatin treatment significantly increased EPC in the hypercholesterolemic group, but failed to improve the EPC levels in the SSc patients, mainly in patients with late disease. Baseline levels of CEC were significantly higher in SSc patients compared with controls and at the end of the treatment they were significantly decreased. Regarding other markers of endothelial activation, we found that all the cytokine levels decreased in a statistically significant manner in the treated patients. CONCLUSION Treatment with simvastatin results in rapid and significant improvement of measures of endothelial activation, suggesting a potential role of statins in the treatment of peripheral vascular disease in SSc. The lack of effect on increase of EPC confirms our previous findings of a defective endothelial stem cell recruitment in the bone marrow of SSc patients. This could indicate that the potential effectiveness of statins in SSc could mainly be ascribed to their effectiveness in modulating endothelial activation mechanisms.

Abstract
OBJECTIVE To develop valid instruments for the assessment of disease-related damage and disease activity in Sjögren's syndrome (SS). METHODS Data on 206 patients with primary SS were collected in 12 Italian centers. Each patient was scored by 1 investigator, on the basis of a global assessment of the degree of disease damage and disease activity. Patients judged to have active disease at the time of enrollment underwent a second evaluation after 3 months. Univariate and multivariate analyses were performed to select the clinical and serologic variables that were the best predictors of damage and of disease activity, and these variables were used to construct the Sjögren's Syndrome Disease Damage Index (SSDDI) and the Sjögren's Syndrome Disease Activity Index (SSDAI). The weight of each variable in the index was determined by the beta coefficients in multivariate regression models. Scores obtained using the SSDDI and the SSDAI were compared with scores initially given by the investigators. Finally, a receiver operating characteristic (ROC) curve was used to determine the cutoff value in the SSDAI with the highest level of accuracy in identifying patients with a significant level of disease activity. RESULTS A multivariate model with 9 variables was the best predictor of investigator scores of damage. The scores obtained using the SSDDI were closely correlated with investigator ratings (R = 0.760, P < 0.0001). A model composed of 11 variables was the best predictor of investigator scores of disease activity. The scores obtained using the SSDAI were strongly correlated with the investigator ratings both at the time of enrollment and 3 months after enrollment (R = 0.872, P < 0.0001, and R = 0.817, P < 0.0001, respectively). The differences between scores given by investigators at study enrollment and after 3 months, a measure of variation of disease activity over time, were also closely correlated with the differences calculated using the SSDAI (R = 0.683, P < 0.0001). The ROC curve analysis showed that patients with the highest level of disease activity could be identified on the basis of an SSDAI score of >or=5. CONCLUSION Our findings indicate that the SSDDI is an adequate instrument to objectively measure damage in patients with SS, and that the SSDAI is a valid tool to measure disease activity when used either as a single-state index or as a transition index.

Abstract
OBJECTIVE Vascular abnormalities represent the main component of the pathobiology of systemic sclerosis (SSc), progressing from structural derangements of the microcirculation with abortive neoangiogenesis to final vessel loss. Since circulating endothelial progenitor cells (EPCs) are important in the vascular repair process, we undertook this study to examine their numbers in the peripheral blood (PB) of SSc patients and to evaluate whether their status is related to impaired quantitative and/or qualitative aspects of the bone marrow (BM) microenvironment. METHODS Circulating EPCs from 62 SSc patients were evaluated by flow cytometry and characterized as CD45 negative and CD133 positive. BM EPCs, identified as CD133 positive, were isolated from 14 SSc patients and grown to induce endothelial differentiation. In addition, progenitor numbers and functional properties of hematopoietic and stromal compartments were analyzed by various assays. RESULTS We found that EPCs were detectable in the PB of patients with SSc, and their number was significantly increased in patients with early-stage disease but not in those with late-stage disease. All of the examined BM samples contained reduced numbers of EPCs and stromal cells, both of which were functionally impaired. Both endothelial and stromal progenitors expressed vascular endothelial growth factor receptor, indicating that BM is strongly induced to differentiate into the endothelial lineage; furthermore, only BM EPCs from patients with early disease led to endothelial differentiation in vitro. CONCLUSION This study provides the first demonstration that in SSc, there is a complex impairment in the BM microenvironment involving both the endothelial and mesenchymal stem cell compartments and that this impairment might play a role in defective vasculogenesis in scleroderma.

Abstract
OBJECTIVE Systemic lupus erythematosus and rheumatoid arthritis represent independent risk factors for atherosclerosis (ATS), although this may be confounded by continuous pharmacologic treatment. Primary Sjögren's syndrome (SS) shares several features of these diseases and may therefore represent an interesting model for verifying the presence of accelerated ATS in the absence of pharmacologic interference. The present study therefore used this model to describe the presence of accelerated ATS in a group of young women. METHODS Thirty-seven untreated white women with primary SS were evaluated clinically and serologically. Carotid and femoral artery intima-media thickness (IMT) was evaluated in the patients and in 35 age-matched healthy women who served as controls. RESULTS The patients had a higher IMT than did the controls at both the carotid (mean +/- SD 0.82 +/- 0.24 mm versus 0.63 +/- 0.20 mm; P < or = 0.001) and the femoral (0.81 +/- 0.26 mm versus 0.67 +/- 0.23 mm; P < or = 0.019) levels, and had a higher prevalence of carotid intima-media thickening (49% versus 11% of controls; P < or = 0.001). The patient subset with high carotid IMT showed an increased prevalence of leukopenia and circulating anti-SSA antibodies; interestingly, the number of leukocytes was inversely correlated with the level of arterial IMT in patients with SS. Multivariate analysis demonstrated that anti-SSA antibodies were independent predictors of carotid artery thickening, while leukopenia was a predictor of both carotid and femoral artery thickening. CONCLUSION Subclinical ATS was evident in about one-half of the patients with SS. Its association with some features typical of connective tissue diseases, such as the presence of anti-SSA and leukopenia, suggests that the immune dysregulation characterizing this autoimmune disorder may play a key role in inducing early ATS.

Abstract
BACKGROUND The pathogenesis of chronic periaortitis (CP) has not been clarified. The histologic features and the association with autoimmune diseases suggest an immune-mediated disorder with marked inflammatory vascular and perivascular lesions. To clarify the role of vascular damage we looked for the presence and the surface phenotype of circulating endothelial cells (CECs) in the peripheral blood of patients with chronic periaortitis. METHODS Eleven patients with CP were evaluated for the presence of CECs; 9 patients had active and 2 inactive disease. Three patients with active disease were also evaluated 3 months after therapy. Ten atherosclerotic patients, 10 patients with renal insufficiency of variable degree and etiology, and 40 healthy subjects were evaluated as controls. Five-parameter, 3-color flow cytometry was performed with a FACScan. CECs were defined as CD45 negative, CD31, P1H12, and CD36 positive, and activated CECs as CD45 negative and P1H12, CD62 positive. RESULTS The median number of CECs in patients with CP (10(6) cells/mL) was significantly higher than in healthy controls (16 cells/mL, P= 0.0004) and atherosclerotic patients (25 cells/mL, P= 0.0005) Two patients with inactive disease had a CEC count comparable to that of normal subjects. In 2 of the 3 patients reevaluated, 3 months after therapy CEC numbers normalized. Almost all CECs were microvascular in origin and showed an activated phenotype. CONCLUSION The presence of a high number of CECs in the active phase of chronic periaortitis and their normalization during inactive disease suggest that endothelial damage may play a role in the pathogenesis of the disease.

Abstract
In an effort to carry out a more in-depth investigation on the antimicrobial properties of H. perforatum, we have assayed different extracts (MeOH; petroleum ether; CHCl(3) and EtOAc) from the aerial parts of the plant against selected microorganisms. Growth inhibition was observed only for Gram-positive bacteria, B. subtilis and B. cereus being the most susceptible to the tested drugs. The Hypericum extract obtained with EtOAc was the most active. The main constituents of this extract, as determined by HPLC analysis, were flavonoids, hypericins and hyperforins. Incubation of the selected microorganisms with the pure chemicals resulted in a significant inhibition of their growth by hypericin, hyperforin and its stable dicyclohexilammonium salt. Flavonoids appeared inactive at all.

Abstract
OBJECTIVE Circulating endothelial cells (CECs) have been described in different conditions involving vascular injury. Vascular abnormalities play a key role in the pathogenesis of systemic sclerosis (SSc). The aim of this study was to search for the presence of CECs in patients with SSc and to evaluate their clinical associations and possible pathogenic role. METHODS The study cohort included 46 patients with SSc and 40 healthy controls. Five-parameter, 3-color flow cytometry was performed with a FACScan. CECs were defined as CD45 negative, CD34 positive, and P1H12 positive, and activated CECs were defined as CD45 negative and P1H12 positive, CD62 positive, or CD106 positive. Progenitors were identified as CD34 positive and CD133 positive. RESULTS Total and activated CEC counts were significantly higher in SSc patients compared with healthy controls and were positively correlated with the disease activity score. With respect to visceral involvement, significant correlation was observed between the CEC number and the severity of pulmonary hypertension. High levels of endothelial progenitors were observed in patients with SSc, and the counts were higher in the early stages of disease. CONCLUSION The presence of CECs in patients with SSc may represent direct evidence of endothelial disease and may be a promising new clinical marker for active SSc. Notably, the association between CECs and pulmonary hypertension and impaired carbon monoxide diffusing capacity was evident in patients with limited cutaneous SSc only, suggesting an important role for CECs in this disease subset with prominent vascular changes. Detection of circulating endothelial progenitors may represent a response to vascular ischemia in early SSc, as an attempt at revascularization.

Abstract
Classification criteria for Sjögren's syndrome (SS) were developed and validated between 1989 and 1996 by the European Study Group on Classification Criteria for SS, and broadly accepted. These have been re-examined by consensus group members, who have introduced some modifications, more clearly defined the rules for classifying patients with primary or secondary SS, and provided more precise exclusion criteria.

Abstract
OBJECTIVES To investigate the clinical and immunogenetic aspects of antibody formation against Ro/SSA and La/SSB as well as their linear B cell epitopes in patients with primary Sjögren's syndrome (pSS) from different European countries. PATIENTS AND METHODS Ninety patients with pSS from six European centres were studied. Serum samples from all patients were tested in a control laboratory for anti-Ro/SSA and anti-La/SSB autoantibodies by RNA precipitation assay and autoantibodies to the previously reported B cell linear epitopes of Ro 60 kDa (p169-190aa and p211-232aa) and La/SSB (p147-154aa, p291-302aa, p301-318aa, and p349-364aa). DNA from 88 patients was used for the determination of HLA-DRB1, -DQA1, and -DQB1 genotypes. Analysis of the results was performed in the 88 patients who were genotyped and tested also for antipeptide antibodies. RESULTS Antibodies to B cell epitopes of Ro 60 kDa were detected at a low frequency (range 10-37%). In contrast, B cell epitopes of La/SSB were detected frequently (range 58-86%) among the anti-La/SSB positive sera. Autoantibodies to the La/SSB epitope, p349-364aa, were significantly positively associated with longer disease duration (p<0.05), recurrent or permanent parotid gland enlargement (p<0.005), and a higher proportion of non-exocrine manifestations (p<0.005), compared with patients without autoantibodies. The presence of anti-Ro/SSA and anti-La/SSB autoantibodies was significantly associated with the presence of HLA-DRB1*03 and DQB1*02 (p=0.038 and p=0.034, respectively). This association was even more prominent and extended to HLA-DQA1*0501 when patients were stratified according the presence of autoantibodies to discrete La/SSB B cell epitopes in comparison with autoantibody negative patients (p<0.01). They were found also to be highly associated with the alleles HLA-DQB1*02 and HLA-DQA1*0501 as well as the presence of a shared amino acid motif in the region 59-69aa of DQB1 first domain (p<0.01, respectively). CONCLUSIONS Autoantibodies against La/SSB, binding to four synthetic peptides, derived from the sequence of the La protein were identified with increased frequency in sera of patients with pSS. The formation of autoantibodies against B cell epitope analogues of La/SSB in European patients with pSS may be dependent on the presence of a permissive HLA-DQ heterodimer, most prominently represented by the HLA-DQA1*0501/DQB1*0201 heterodimer, suggesting that a model of HLA restricted presentation of La/SSB peptide determinants is crucial for the autoimmune response against La/SSB.

Abstract
The aim of this study is to outline the mechanisms leading cochlear cells to die. We utilized an immortalized cell line (OC-k3 cells) derived from the organ of Corti of transgenic mice in order to perform in-depth biochemical studies with no limitations on sample size and number. We probed these cells with cisplatin and gentamicin, two drugs which display in vivo undesired ototoxic side-effects. We investigated cell viability, reactive oxygen species (ROS) production and glutathione (GSH) levels and tested the effects of different concentrations of cisplatin and gentamicin from 0 to 48 h. Results show that cells undergo a dose- and treatment-time-dependent apoptosis characterized by nuclear fragmentation, integrity of the cell membrane and mitochondria, and absence of DNA endonuclease activity. During the early part of treatment, ROS production increases and intracellular GSH decreases, probably due to the activation of protein kinase C alpha. Use of antioxidants such as N-acetylcysteine, GSH and vitamin C rescues cells from apoptosis almost completely. Overall, these data indicate that ROS generation might play a central role in inducing inner ear cell apoptosis and may have an additive role in the ageing process.

Abstract
AIM To determine whether the European Consensus Lupus Activity Measurement Index (ECLAM) can be used to evaluate disease activity in patients retrospectively from the data provided in their clinical charts. METHODS The ECLAM score was calculated twice in a series of 64 consecutive SLE patients: first for each patient during the course of a standard clinical evaluation (direct-ECLAM), and then one to two weeks later solely on the basis of the data provided in the patient's clinical chart (chartECLAM). The scorings for each patient were performed by two different assessors. RESULTS The direct-ECLAM and chart-ECLAM scores were highly correlated (Spearman's rank correlation coefficient = 0.86). The regression line was not significantly different from the identity line (t-test). The Pearson's coefficient was 0.88. The interobserver variability of the chart-ECLAM showed a low inter-rater variability. CONCLUSION ECLAM could represent a valid and reliable instrument for the retrospective analysis of disease activity in SLE patients.

Abstract
Six different mixtures of garlic distilled oils containing diallyl disulfide (DDS) and diallyl trisulfide (DTS), ranging from 1 to 51% and 88 to 38% respectively, have been assayed against a number of yeasts (C. albicans, C. tropicalis and B. capitatus), gram-positive bacteria (S. aureus and B. subtilis) and gram-negative bacteria (P. aeruginosa and E. coli). Results obtained support a specific antifungal more than an antibacterial activity and implicate DDS as the active constituent. Incubation of garlic extracts made up of 1% DDS and 88% DTS resulted, in fact, in the absence of growth inhibition against all the tested microorganisms, whereas garlic oils with higher quantities of DDS showed significant inhibitory activity, increasing with the increase of DDS amount.

Abstract
OBJECTIVE Helicobacter pylori infection elicits a local and systemic immune response against bacterial antigens, including a heat-shock protein of 60 kDa (HSP60). The homology between microbial and human HSP suggests that the immune response to bacterial HSP may play a role in the pathogenesis of autoimmune disorders. Since gastric involvement and H. pylori have been reported in Sjögren's syndrome (SS), we investigated the prevalence of antibodies against H. pylori and its specific HSP60 in sera from patients with SS. METHODS Four groups of patients were studied. Group 1, 34 patients with primary SS (pSS); Group 2.19 patients with secondary SS; Group 3, 22 patients with various autoimmune diseases and Group 4, 43 healthy controls. Serum IgG levels against HSP60 were determined by an ELISA using recombinant full length HSP60 expressed in Escherichia coli, as the antigen. To confirm the H. pylori infection, a commercial ELISA was used. RESULTS Out of 34 patients in Group 1, 27 (79.4%) and 30 (88.2%) had antibodies against H. pylori and its HSP60, respectively. The prevalence was significantly higher than that found in Group 3 (18.2%, p < 0.0001 and 27.3%, p < 0.0001) and in Group 4 (48.8%, p < 0.005 and 37.2%, p < 0.0001) but not than that of Group 2 (48.8% and 37.2%). If the prevalence of patients either positive or negative for both antibodies was considered, a statistically significant difference was found between Group I and respectively Groups 3 and 4. CONCLUSION The hypothetical role of HSP60 in the development of the immune response both in pSS and secondary SS seems strictly linked to the prevalence rate of H. pylori infection.

Abstract
Between 1990 and 1995 a European Consensus Group carried out a multicenter study to reach agreement of the definition of disease activity in systemic lupus erythematosus (SLE). A new index, the European Consensus Lupus Activity Measurement (ECLAM) index, was developed. In a second phase of the study, a prospective survey aimed at validating ECLAM and 4 other scales as steady-state and transition indices for disease activity in SLE was completed. We present the results of this survey. A standardized clinical chart was developed, together with a computer program that could automatically calculate the ECLAM score, as well as the scores for some of the disease activity scales most widely used at present, i.e., the British Isles Lupus Assessment Group, Systemic Lupus Activity Measure, SLE Disease Activity Index, and the SLE Index Score (SIS). With the participation of 28 centers in 15 different European countries, data from 121 prospectively selected new lupus patients were collected. The validity of the 5 activity scales was assessed by comparing the computed scores for each patient to a gold standard, i.e., the physician's subjective judgment on disease activity measured using a semiquantitative scale. All the indices were found to be valid instruments for measuring disease activity in SLE in both the steady-state and transition phases. The results for the various indices closely correlated with one another. Thus, the computerized chart developed by the European Consensus Group offers a simple and reliable instrument to assess disease activity and could be used to monitor lupus patients both in clinical practice and in clinical trials.

Abstract
Classification criteria currently exist for most of the rheumatic diseases. Different criteria sets have also been proposed in the past for Sjögren's syndrome (SS), but none of these has been validated and no single one is in general use by the entire scientific community. Between 1988 and 1996 the European Study Group for the Classification Criteria for SS performed a multicenter study in which a new classification criteria set for this disease was defined and then validated. This European set of classification criteria for SS is rapidly becoming the most widely accepted procedure to classify patients with the primary and secondary variants of the syndrome.

Abstract
The chemical investigation of the essential oils from the aerial organs of Bellis perennis L., the common daisy, showed that polyacetylenes were one of the dominant class of compounds. The major constituents, methyl deca-4,6-diynoate and deca-4,6-diynoic acid, and their structural analogues, deca-4,6-diyne, dimethyl octa-3,5-diyne-1,8-dioate and deca-4,6-diyne-1,10-dioic acid, were synthesised and their antimicrobial activity evaluated. Only deca-4,6-diynoic acid and deca-4,6-diyne-1,10-dioic acid showed antimicrobial activity, being the two compounds mainly effective against Gram-positive and Gram-negative bacteria, respectively. Structure-activity relationships of the tested polyacetylenes are discussed.

Abstract
The aim of this study was to investigate the possible relationship between the degree of inflammatory infiltration of salivary glands in Sjögren's syndrome (SS) and the different demographic, clinical and serological features of the disease. A quantitative assessment of the extension of the infiltrates was performed on histology samples from the labial salivary glands (LSG) of 82 patients with primary SS, by calculating the ratio of the infiltrated area to the total area of glandular tissue in the samples. The correlations between the amount of inflammatory infiltrate and the main features of the disorder were then analysed. A significant negative correlation between the degree of LSG infiltration and the patient's age at disease onset was observed (P < 0.05). In contrast, the percentage of infiltrate did not correlate with the disease duration. A significant correlation was found between the degree of infiltration of the salivary tissue and (i) the total number of extraglandular features (P < 0.01) and (ii) the presence of specific extraglandular features such as Raynaud's phenomenon (P < 0.05), vasculitis (P < 0.0001), lymph node or spleen enlargement (P < 0.05) and leucopenia (P < 0.02). Finally, patients with antinuclear antibodies, anti-SSA/Ro antibodies, or anti-SSA/Ro plus anti-SSB/La antibodies showed a more widespread inflammatory infiltration in the LSG tissue than patients without these autoantibodies (P < 0.01). The degree of infiltration in the salivary tissue was significantly greater in those patients with anti-SSA/Ro plus anti-SSB/La antibodies in their sera than in patients with anti-SSA/Ro antibodies alone (P < 0.05). In conclusion, patients with SS and active inflammatory infiltration of the salivary glands usually experience an earlier disease onset and a larger number of systemic extraglandular manifestations. In addition, the antibodies directed against certain nuclear/cytoplasmic specificities, and particularly those which react with the SSB/La antigen, seem to play a key role in enhancing the autoimmune process in the salivary glands.

Abstract
OBJECTIVE To assess the practice patterns in the management of lupus nephritis (LN) of physicians dealing with systemic lupus erythematosus. METHODS A multiple choice questionnaire was sent to 135 lupus centers, mainly in Europe. It was divided into 4 sections, one of which regarded LN. Sixty-one centers (40%) sent the questionnaire back before the meeting; however two of them did not fill out the LN section. Therefore, 59 valid LN questionnaires were collected and analyzed. Statistical evaluation was performed using frequency analysis and the chi-square test. RESULTS In 50 centers (85%), renal biopsy is performed in all patients with clinically evident renal involvement, and in most of them it is repeated in cases of relapse and/or ineffectiveness of treatment. Oral steroid alone is the therapy preferred by 67% of responding physicians in patients with WHO class II LN. Multi-drug therapy is favoured by 57% in patients with class III LN, by 79% for mild-to-moderate forms of class IV LN (IVm), by 84% for moderate-to-severe forms of class IV LN (IVs), by 47% for mild-to-moderate forms of class V LN (Vm), and by 65% for moderate-to-severe forms of class V LN (Vs). Steroids plus cyclophosphamide (CYPH) is the association most commonly used for class III, IVm and IVs LN, having been indicated by 70%, 80% and 88% of the centers, respectively. Furthermore, pulse CYPH is largely preferred to oral CYPH by the majority of centers. It is worth noting that 41 centers (70%, p < 0.01) utilise the same drugs in the treatment of both WHO class IVm and IVs LN. No clear trends in the use of multi-drug associations were identifiable in the treatment of class V LN. Moreover, most of the centers (64%) said that they rely on histologic parameters in order to define renal prognosis and that they consider the chronicity index to be the best predictor of poor renal outcome (74% of the centers). CONCLUSIONS It was possible to identify some clear trends in the behaviour of physicians who are "expert" in lupus patients: (i) they perform a renal biopsy in order to charaterize the LN and repeat it when they are faced with relapse or ineffective therapy; (ii) they treat WHO class II LN with oral steroids alone and class III and IV LN with steroids associated with CYPH (CYPH, generally in a pulse regimen); and (iii) they define renal prognosis by means of histologic predictors, especially the chronicity index. However, no trend seemed to exist for the treatment of class V LN, particularly Vm.
