Abstract
BackgroundSystemic Sclerosis (SSc) is a complex autoimmune disease characterized by vascular damage, immune activation and fibrosis of skin and internal organs (1,2). One of the most common and severe SSc manifestations is interstitial lung disease (ILD) (3).ObjectivesEvaluate tolerability and safety profile of Nintedanib in patients with SSc-related ILD.MethodsWe enrolled 11 consecutive patients (6 female, 5 male, Mean age 62.7 ± 8 SD, disease duration (from the first Non-Raynaud symptom) 8 years (± 7SD) who referred to our Scleroderma Units during the last twelve months. Patients fulfilled EULAR/ACR classification criteria (4) for SSc. Patient was assessed by means of clinical evaluation (baseline and every three months), High Resolution computed tomography (every six month, or sooner), respiratory function test (every three to six months), laboratory work up, nailfold videocapillaroscopy, echocardiogram, and clinical questionnaires (BORG and mMRC).ResultsNSIP was the most frequent HRCT pattern (5 pts, 45%), followed by UIP and UIP/NSIP pattern (respectively 3 pts & 3 pts, 27%). 9 patients showed more than 20% of HRCT pulmonary fibrosis involvement. Only 1 patient had a history of smoking. mRSS was 9.23 (±10SD) points with any significant improvement during the twelve months follow-up (10 ±10SD). 8 pts were on Micophenolate Mophetil (MMF) (7 of them on MMF + steroids), 8 patients were on steroids (mean dose 5 mg/day of Prednisone or equivalent), 3 on rituximab. Main FVC was 2347 ml [+/- 1051 ml] (61.3% predicted) remaining stable. The mmRC decrased from 2.36 at baseline to 2.27 at the end of the follow up and Borg ameliorated from 7.27 at baseline to 6. Two patients were on oxygen therapy (O2 3l/min) with any significant airflow adjustment. Three patients reported irrepressible diarrhea, one patient had a partial intestinal obstruction, one had pulmonary arterial hypertension worsening with an immediate drug withdraw, one patient presented nausea, one irritability. Three patients had a clinical irrelevant weight loss (less than 2 Kg).Conclusionwe report a preliminary real-life experience on the use of Nintedanib in SSc-related patients, focusing in particular to its tolerability and safety profile. Nintedanib is well tolerated with a low rate of definitive discontinuation due to SAE. Diarrhea is a very frequent adverse event (approximately 5 episodes a day) and had led to dose reduction and/or treatment re-challenge in the majority of patients. Diarrhea seems to ameliorate reducing daily dose of MMF (1 gram/day) or precribing loperamide along with diosmectite and probiotics. FVC, mRSS, HRCT and capilalroscopy pattern remained stable. Further studies are desirable to confirm the usefulness of Nintedanib in progressive ILD, but based on our experience we support the combined use of the anti-fibrotic therapy plus immunomodulatory drugs in early stages of SSc-related ILDReferences[1]LeRoy EC, Black C, Fleischmajer R, Jablonska S, Krieg T, Medsger TA, et al.

Abstract
BackgroundSystemic Sclerosis (SSc) is a complex autoimmune disease characterized by vascular damage, immune activation and fibrosis of skin and internal organs 1. Raynaud phenomenon (RP) is frequently the first symptom of the disease and growing evidences are supporting the hypothesis the SSc may be a vascular disease, with a pivotal role of endothelial cells, particularly in the very early phase2,3. Robust data support the use of vascular active drug to treat RP and to prevent vascular complication4–7.ObjectivesThe use of prostacyclin analog (PA) is evertything but standardized, with different regimen used all around the Country. We report data on the use of PA in a multicentric regional reality to understand which regimen are prevalent (and why) and if there is the opportunity to standardized them.MethodsWe collected data from an online survey exploring different items related to the use of PA.ResultsSurvey was fullfilled by 12 sites: 5 university hospital and 7 local hospitals, 7 driven by Rheumatologist and 5 from internal medicine specialists with/without concomitant rheumatologists. PA are ubiquitarly used for SSc-related digital ulcers (SSc-DU) and secondary RP but only a half of sites use it for primary RP. Seventy-five percent of sites (9/12) dispense PA at least once a month, but some other (1 each one respectively) on weekly basis, every other month or every 7 weeks. Drug administration may last from 2 to 5 consecutive days (mean 1.91+/- 1.5SD) with drug dose ranging from 0.5 to 2 ng/Kg/min with a minimum variability from site to site. Our regional hospitals may count on overall 68 spots, some available as beds (outpatient or inpatient), some as reclining chair or chair (outpatients only). University centers have usually more assigned personnel than local hospital (on average: 2 versus 1.5 physicians, 2 versus 1.2 nurse). Sites are able to offer meals (except one) and are able to accomodate from 1 to 12 patients at the same time (mean 3.45, +/- 3.2SD).ConclusionPA has known benefit in vascular involvement in SSc patients. Despite a multicenter palcebo-control study8 defining time and dose of this drugs and subsequent data based on the same regimen9, there is no homogeneity in treatment administration. The unequal treatment, based on our data, seems due to limited resources and personnel. High variability has been found in regimen duration and administration frequency.References[1]Ferri, C. et al.

Abstract
Background:Fibromyalgia (FM) patients report chronic widespread pain, fatigue, cognitive difficulties and sleep disturbances, often associated with anxiety and/or depression (1). FM syndrome more frequently affects women and many papers describe gender-related differences in the perception, description and expression of pain (2), but up to now, the impact of gender on the clinical severity of FM is still a controversial topic.Objectives:The aim of this study was to analyse the data from a web-based registry of FM patients in order to detect a relationship between gender and disease severity.Methods:Adult patients with FM, diagnosed on the basis of the 2010/2011 American College of Rheumatology (ACR) diagnostic criteria (3), were recruited at 19 Italian rheumatology centres between November 2018 and April 2019. Those affected by other conditions that could interfere with the assessment of FM, e.g. psychiatric disorders, were excluded from the study. The severity of the disease was evaluated by validated FM-specific questionnaires: the revised Fibromyalgia Impact Questionnaire (FIQR) (4), the modified Fibromyalgia Assessment Status (ModFAS) questionnaire (5), and the Polysymptomatic Distress Scale (PDS) (6). The data obtained were collected in the Italian Fibromyalgia Registry, an online registry created with the support of the Italian Society of Rheumatology (SIR).Results:We analyse data from 2.381 patients affected by FM, 2.184 females (91.7%) and 197 males. No significant differences in mean age, disease duration, or BMI between the two genders were reported. The women expressed greater disease burden as indicated by higher scores for each completed test: higher mean ModFAS score (25.23 ± 8.83 Vs 23.37 ± 9.22; p = 0.005), mean FIQR score (58.62 ± 23.22 Vs 51.68 ± 23.06; p <0.001), and mean PDS score (18.77 ± 7.34 Vs 17.19 ± 7.25; p = 0.004). Figure 1 shows the mean scores of each item of the FIQR divided by gender. Women reported significantly higher values on all the items of FIQR except three (feeling overwhelmed, FIQR-11; depression, FIQR-16; and anxiety, FIQR-18). It is interesting to note that men self-reported higher levels of depression (FIQR-16).Figure 1.Mean scores for each FIQR item by gender.Conclusion:Our findings demonstrate that women with FM are globally more impaired than men (even if some psychological aspects of the disease are comparable), thus reinforcing the idea that gender plays a role in symptoms and functional impairments associated with the disease.References:[1]Clauw DJ.

Abstract
Background:Fibromyalgia syndrome (FM) is characterised by a complex symptom spectrum, dominated by the presence of chronic widespread pain, fatigue and unrefreshing sleep. FM affects between 2 and 3% of the general population. It is a condition that mainly involves middle-aged women, although it is increasingly being diagnosed in younger people. The severity of symptoms can vary greatly between individual patients, and is influenced by many factors (e.g. sex, body mass index) [1]. To date, there is little information about changes in severity in accordance with patient age.Objectives:The aim of this study was to investigate variations in symptom severity in FM patients according to age categories.Methods:A cross-sectional study of adult FM patients diagnosed according to the American College of Rheumatology 2010/2011 criteria was performed. The case series was included from an Italian national registry [2]. Patients were grouped according to five age categories: 18-40 years, 41-50 years, 51-60 years, 61-70 years, over 71 years. Symptom severity was assessed through the revised Fibromyalgia Impact Questionnaire (FIQR) and domains, including FIQR physical function (items 1-9), FIQR health status (items 10-11), and FIQR symptoms (items 12-21). Between-group characteristics were analysed using one-way analysis of variance (ANOVA).Results:This study included a total of 2889 patients, 403 aged 18-40 years, 756 aged 40-50 years, 1035 aged 50-60 years, 528 aged 60-70 years, and 167 over 70 years, respectively. The mean (standard deviation [SD]) score of the total FIQR was 52.68 (11.82). Total FIQR and individual domains all showed a normal distribution. Analysing the data by age category, there were statistically significant differences between the categories for the total FIQR (p = 0.030). The age categories with the highest disease severity were those above 71 years (FIQR 62.14, SD 22.45), and between 51-60 years (FIQR 60.31, SD 22.89) (Table 1). Significant differences between age categories were also found for the domains physical function (p = 0.006) and health status (p = 0.012), but not for the domain symptoms (p = 0.164).Table 1.Mean values of FIQR total score and domains according to age categories.FIQR and domains18-40 years41-50 years51-60 years61-70 years≥71 yearsp*FIQR total, mean (SD)57.90 (21.76)59.25 (23.30)60.31 (22.89)57.13 (23.59)62.14 (22.45)0.030FIQR physical function, mean (SD)15.51 (7.56)16.44 (7.77)16.77 (7.51)15.96 (7.82)17.68 (7.26)0.006FIQR health status, mean (SD)11.19 (5.85)11.24 (5.99)11.49 (5.93)10.57 (6.11)12.21 (5.97)0.012FIQR symptoms, mean (SD)31.32 (10.48)31.56 (11.32)32.10 (11.01)30.68 (11.47)32.24 (11.34)0.164Abbreviations and legend. FIQR = revised Fibromyalgia Impact Questionnaire; SD = standard deviation; * = one-way analysis of variance (ANOVA).Conclusion:Distinguishing the disease severity in FM patients according to age categories, a bimodal distribution emerges, with the disease severity being greatest in patients over 71 years and in the 51-60 years decade. The main differences in severity, according to what can be detected through the FIQR, are attributable to the domains physical function and health status, which show higher scores in the two classes with higher severity.References:[1]Sarzi-Puttini P et al., Fibromyalgia: an update on clinical characteristics, aetiopathogenesis and treatment.

Abstract
Background:contrast-enhanced ultrasonography (CEUS) has been proposed as a tool to assess myositis, but data in the literature are still scarce (Radiologe 2018;58:579).Objectives:to evaluate CEUS as a tool to assess myositis patients and its accuracy in differentiating myositis from common mimickers.Methods:16 patients with myositis (4 polymyositis, 6 dermatomyositis, 2 immune-mediated necrotizing myopathy, 1 inclusion body myositis, 2 overlaps Sjøgren’s syndrome - myositis and 1 Enterovirus-reactive myositis) and 4 controls (2 peripheral neuropathy, 1 limb girdle muscle dystrophy, and 1 metabolic myopathy) underwent after rest CEUS (Esaote MyLab, linear probe 13-5 MHz, Sonovue®) at a room temperature of 20° of the vastus lateralis and medialis muscles. CEUS was performed by 2 ultrasonographists with an expertise in muscle US blinded to the clinical data of the patients. CEUS muscle signal was expressed on a 0-4 scale as described in J Rheumatol 2001; 28:1271 per each muscle group and the global score was divided by four. Creatine kinase (CK), manual muscle test (MTT) and MRI of the thigh muscles were performed within maximum one month from the CEUS. MMT was expressed using the 0-5 Medical Research Council scale; intermediate points were converted into decimals as detailed in Kendall FP et al, Muscle Testing & Function: Testing and Function with Posture and Pain. 5th ed., Lippincott Williams & Wilkins, 2005. MRI of the thigh muscles was considered positive if it showed muscle edema. Myositis was defined active if CK was raised above the reference range and/or MMT showed progressive worsening. Results were expressed as median (range). Between-group comparison was performed with Mann-Whitney test. Statistical analysis was performed with SPSS version 20. The study was approved by the Ethics Committee and all patients provided their written consent.Results:Median (range) age was 38 (69) years in the myositis and 41 (45) years in the control group (p=0.89). Disease duration in the myositis group was 60 (334) months. CEUS muscle score was 0.5 (3) in the myositis group and 2 (3) in the control group (p=0.99). In the myositis group, CEUS score did not differ between treated and untreated patients (p=0.84). CK values were 361 (6442) in the myositis group and 363 (799) in the control group (p=0.68). MMT was significantly lower in the myositis group [4.33 (2)] than in the control group [4.94 (0)] (p=0.038). CEUS was 77% (47-05 95% confidence interval) sensitive and 67% (9-99% 95% confidence interval) specific for a diagnosis of myositis. CEUS was positive in 10/13 patients and negative in 3/13 with active myositis, while was negative in 2/3 patients and positive in 1/3 with inactive myositis. Statistically, CEUS did not discriminate between active and inactive myositis (Fisher’s exact test p= 0.21). All controls had a positive CEUS. No association was found between MRI edema and a positive CEUS (intraclass correlation coefficient p=0.5). No correlation was found between CEUS score, on the one hand, and CK levels or MMT, on the other (Spearman’s rho p>0.05).Conclusion:CEUS has moderate sensitivity for a diagnosis of myositis, but does not discriminate between myositis and some of its common mimickers. Larger studies are required to better evaluate the role of CEUS in patients with myositis.Disclosure of Interests:Nicolo Pipitone Consultant of: Received royalties from Uptodate.comInvestigator for the gevokizumab in myositis Servier study (2014), the sirukumab in GCA GSK study (2016), PI for the ToReMy AIFA funded (2017) study and for the FOREUM funded (2018) GCA study, Speakers bureau: Guest speaker at UCB-sponsored meetings: (Immunology Summits, Prague, 2012, 2013 & 2014, MACRO Meet the expert at the ACademy of RheumatOlogy, Bologna 13 - 14 April 2012, GRAPPA Workshop, Milan 29 January 2016 and Rome 30 November 2017), Fininvest (Catania 2016), Aim Group (Reggio Emilia 2018), I&C (Cologna, 2018), Alfa-Wassermann sponsored meeting (Rhewind, Bologna, February 2016 and 2019), Pierluigi Macchioni: None declared, Gianluigi Bajocchi: None declared, Carlo Salvarani Grant/research support from: consulting and investigator fees from Abbvie, Pfizer, MSD, Roche, Celgene, Novartis, Consultant of: consulting and investigator fees from Abbvie, Pfizer, MSD, Roche, Celgene, Novartis

Abstract
The range of pathologies that are related to primitive vasculitis is broad, complex and not as typical as we would expect. Clinicians should be aware that several forms of primitive and systemic vasculitis, regardless of the size of the affected vessel, may exhibit identical histological alterations. This observation has important clinical implications as it means that cases of vasculitis do not correspond clinically and histologically. Thus, while histology remains the diagnostic gold standard, it can be used only as part of the most complete clinical assessment possible. Another point worth of the clinician's attention is that vasculitis histology changes over time, as do disease evolution and activity, even without considering the masking effects of treatment and the possibility of sampling error due to the patchy occurrence of vasculitis. The purpose of this review is to identify the most common forms of vasculitis in clinical practice, and to provide guidance to the clinician on the pathology of the vessels.

Abstract
We present the case of a 48-year-old male with an acute respiratory distress syndrome which later proved to be an unexpected and initial manifestation of antisynthetase syndrome. Recognising this as a rare combination of an acute respiratory failure and a connective tissue disease in a previously asymptomatic subject is possible only by means of diagnostic exclusion. Based on similar case reports, the only way to reverse the disease and minimise the sequelae is to begin long-term immunosuppressive therapy as soon as possible once the diagnosis has been made. A review of similar cases with antibody anti-Jo-1 is presented with the aim of providing clinicians with useful indications for promptly recognising this poorly-defined and life-threatening emergency.

Abstract
Disease activity assessment in large vessel vasculitis (LVV) is often challenging for physicians. In this study, we compared the assessment of disease activity based on inflammatory markers, clinical indices (Indian Takayasu Activity Score [ITAS] and the Kerr/National Institute of Health indices [Kerr/NIH]), and 18F-Fluorodesossiglucose (FGD) vascular uptake at positron emission tomography (Pet). We found that Pet results did not statistically correlate with the clinical indices ITAS and Kerr/NIH, because FDG uptake was increased (grade>2 on a 0-3 scale in at least one evaluated vascular segment) in many patients with inactive disease according to clinical and laboratory parameters (i.e., negative ITAS and Kerr/NIH indices as well as normal erythrocyte sedimentation rate (ESR) and C-reactive protein (PCR)). Similarly, interleukin- 6 and its soluble receptor did not statistically correlate with disease activity. In contrast, clinical indices showed a significant correlation between each other and with inflammatory markers (VES and PCR). These data suggest that while clinical indices and inflammatory markers may be useful to assess disease activity, Pet may be more sensitive.

Abstract
OBJECTIVE To determine the prevalence of and independent factors associated with joint involvement in a large population of patients with systemic sclerosis (SSc). METHODS This study was cross-sectional, based on data collected on patients included in the European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) registry. We queried this database to extract data regarding global evaluation of patients with SSc and the presence of any clinical articular involvement: synovitis (tender and swollen joints), tendon friction rubs (rubbing sensation detected as the tendon was moved), and joint contracture (stiffness of the joints that decreased their range of motion). Overall joint involvement was defined by the occurrence of synovitis and/or joint contracture and/or tendon friction rubs. RESULTS We recruited 7286 patients with SSc; their mean age was 56 +/- 14 years, disease duration 10 +/- 9 years, and 4210 (58%) had a limited cutaneous disease subset. Frequencies of synovitis, tendon friction rubs, and joint contractures were 16%, 11%, and 31%, respectively. Synovitis, tendon friction rubs, and joint contracture were more prevalent in patients with the diffuse cutaneous subset and were associated together and with severe vascular, muscular, renal, and interstitial lung involvement. Moreover, synovitis had the highest strength of association with elevated acute-phase reactants taken as the dependent variable. CONCLUSION Our results highlight the striking level of articular involvement in SSc, as evaluated by systematic examination in a large cohort of patients with SSc. Our data also show that synovitis, joint contracture, and tendon friction rubs are associated with a more severe disease and with systemic inflammation.

Abstract
The knowledge about the risk of pregnancy in vasculitides mostly derives from single case reports or at best from retrospective studies with all the caveats that these observations include. Primary systemic vasculitides are uncommon, encompassing a broad spectrum of severity, from mild to life-threatening manifestations and with different natural histories, from self-limiting to relapsing or chronic active disease. The treatments require a cautious use of immunosuppressants tailored to each specific condition. Furthermore, most of the cytotoxic drugs necessary to treat vasculitis act by modifying the cell cycle and cell differentiation, biological effects that are particularly hazardous for the foetus. In order to have an uncomplicated pregnancy, conception should be planned when the disease is inactive. Moreover, organ failure or damage, due to previous disease activity, must also be taken into account since it can lead to adverse obstetrical and fetal outcomes.

Abstract
OBJECTIVE To test for the autonomic neuropathy in systemic sclerosis (SSc) using cardiovascular reflex evaluation including the "cold face test", which elicits forehead cold receptors (C-fibres). These tests examine the induced bradycardia-hypertensive response and the integrity of nociceptive afferent and parasympathetic-sympathetic efferent pathways. METHODS Twelve SSc patients were studied; including 5 with the limited cutaneous (lcSSc) involvement, and 7 with diffuse cutaneous involvement (dcSSc). All patients were matched with healthy controls. We performed cardiovascular autonomic tests (tilt-test, Valsalva manoeuver, deep breathing, sustained handgrip and cold face) with continuous monitoring of beat-to-beat blood pressure (BP) and heart rate (HR). Baroreceptor sensitivity index (BRSI) and power spectral analysis (PSA) of heart rate variability (HRV) were also evaluated. RESULTS SSc patients showed a statistically significant higher HR at rest (p<0.01), a lower increase of diastolic BP during tilt test (p<0.01). They had suboptimal hypertensive and bradycardic response to the cold face test (Systolic BP: p<0.05; Diastolic BP: p<0.01; HR: p=0.08). The Valsalva manoeuver, deep breathing, isometric handgrip, BRSI and PSA of HRV results were within normal limits in the majority of SSc patients. CONCLUSION In this group of SSc patients cardiovascular reflexes were normal, whereas the cold face test which acts through cutaneous nociceptive sensory fibres was abnormal in almost all patients. These results suggest that insufficiency of epidermal small fibres (C-fibres) is involved in SSc.

Abstract
OBJECTIVE To evaluate the impact of traditional cardiovascular risk factors, carotid atherosclerosis and the effect of anti-platelet/anti-coagulant therapy on the occurrence of severe cranial ischaemic events (CIEs) in GCA. METHODS We identified 180 Reggio Emilia (Italy) residents with biopsy-proven GCA diagnosed between 1986 and 2005. We evaluated data on demographics, clinical features, laboratory investigations, cardiovascular risk factors, anti-platelet/anti-coagulant use and carotid atherosclerosis. RESULTS Systemic signs/symptoms were significantly less frequent (P = 0.004) and ESR and C-reactive protein (CRP) values at diagnosis were significantly lower (P = 0.03 and P = 0.04, respectively) in patients with CIEs. The prevalence of hypertension and ischaemic heart disease was significantly higher in patients with CIEs than in those without (P = 0.01 and P = 0.006, respectively). Patients treated with anti-platelet/anti-coagulant therapy were significantly more likely to suffer CIEs than those without (P = 0.03), while CIEs were significantly associated with ischaemic heart disease in this subset of patients (P = 0.02). By multivariate logistic regression, we found that the best predictors for the development of severe CIEs included the absence of high (>5.38 mg/dl) CRP levels at diagnosis (OR = 0.31, 95% CI 0.08, 1.20), the absence of systemic manifestations (OR = 0.30, 95% CI 0.08, 1.08), the presence of hypertension (OR = 7.77, 95% CI 0.83, 72.76), and a past history of ischaemic heart disease (OR = 8.65, 95% CI 0.92, 80.95). CONCLUSIONS In GCA, hypertension, a past history of ischaemic heart disease and a low inflammatory response are associated with a higher risk of developing severe CIEs.

Abstract
We describe a case of giant cell arteritis (GCA) of the female genital tract. Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET) and CT-scan showed evidence of large-vessel vasculitis involving the thoracic aorta and its branches, while temporal artery biopsy showed arteritis despite the absence of clinical manifestations suggestive of GCA. We review the literature and discuss the relationship between "cranial" GCA, large-vessel GCA and female genital GCA.

Abstract
Giant cell arteritis is usually a self-limiting disease with a variable duration of months to years. However, in a subset of patients the disease may follow a protracted course, requiring long-term treatment with glucocorticoids. To date, glucocorticoids are the only agents whose efficacy has been unquestionably proven. More specifically, they can both improve the clinical symptoms of giant cell arteritis and also prevent its complications, including visual loss. Glucocorticoids therapy is notoriously fraught with numerous side effects, therefore it is sensible to taper glucocorticoids as quickly as possible. Flares are not uncommon and tend often to occur upon tapering of glucocorticoids dosage or on withdrawal of glucocorticoids therapy. However, in most cases flares are mild and appear to respond favorably to an increase in glucocorticoids dosage or reintroduction of glucocorticoids therapy, respectively. Mortality rates of giant cell arteritis patients are comparable to those of the general population, but there is evidence for an increased frequency of potentially life-threatening ischemic events, such as myocardial infarction and cerebro-vascular accidents, especially early on in the disease course. The risk conferred by the disease appears to decrease with time, presumably as a consequence of glucocorticoids treatment, whereas it can remain significantly elevated in patients whose disease activity is not sufficiently controlled by the treatment. By contrast, there is no evidence that giant cell arteritis is associated with an increased prevalence of malignancies or that it may represent a paraneoplastic syndrome.

Abstract
The presentation, severity and prognosis of rheumatoid arthritis (RA) differ depending on the age of disease onset. Elderly onset RA (EORA: age of onset > 60 years) has been reported to differ from younger-onset RA (YORA) by a more balanced gender distribution, a higher frequency of acute onset often associated with systemic features, more frequent involvement of the shoulder girdle and higher disease activity. To add to our knowledge of this disease, 101 EORA and 88 YORA patients, not previously treated with DMDARs or steroids, were studied and compared, paying particular attention to the onset. The female to male ratio was higher in the YORA group (4.4:1 vs 1.6:1; p < 0.05). The disease duration was similar: 5.6 +/- 3.3 months in EORA and 7.9 +/- 3.8 months in YORA. EORA presented a more frequent acute onset (33.6% vs 13.6%; p < 0.05) especially if rheumatoid factor was absent. This subset also showed more frequent polymyalgic onset. Constitutional symptoms (fever, weight loss, fatigue) were more frequent in EORA patients without differences between seropositive and seronegative patients. The distribution of involved joints showed a significantly higher frequency of shoulder involvement in EORA (64% vs 38%; p < 0.05) and of feet involvement in YORA (25% vs 52%; p < 0.05). Hands and wrists were the most frequently involved joints in all patients.

Abstract
Acquired deficiency of clotting factor VIII (FVIII) is a rare bleeding diathesis seldom encountered in systemic lupus erythematosus (SLE). Reduction of FVIII activity by autoantibodies can cause potentially life-threatening situations. Herein, an SLE patient with a positive lupus anticoagulant (LAC) test who abruptly developed metrorrhagia 4 yr after diagnosis is reported. Coagulation tests revealed FVIII activity reduced to 3% and a prolonged aPTT. FVIII inhibitor(s) were found to be as high as 3.0 Bethesda Units. Plasmapheresis, immunoglobulins, prednisolone and FVIII plasma concentrates induced the cessation of metrorrhagia, but the clotting tests were barely improved. One month later, extensive ecchymosis appeared and worsened, despite re-administration of the previous therapy. Pulse cyclophosphamide followed by oral administration was then started with normalization of coagulation parameters and long-lasting disease remission.

Abstract
To evaluate nervous system involvement in a cohort of Italian patients with primary Sjögren's syndrome (pSS), 87 unselected patients (83 female, and four male) observed consecutively at our institution over a period of 5 years were screened by clinical and instrumental (MRI, SPECT, electrophysiological testing, CSF analysis) investigations for peripheral and central neurological abnormalities. Seroimmunological parameters and extraglandular features other than neurological manifestations were also evaluated. Seven patients had central nervous system (CNS) disease (8%), mostly non-focal dysfunction, and 12 had peripheral nervous system (PNS) disease (13.8%), mostly mild or severe sensory or sensory-motor polyneuropathies. One patient had concomitant CNS and PNS involvement. Compared with CNS disease, PNS involvement occurred in older patients (> 50 years), independent of the disease duration. Patients with and without neurological abnormalities did not differ for seroimmunological parameters (including antiphospholipid antibodies) or extraglandular manifestations. From a statistical point of view, the only relevant finding was the detection of a slight increase in serum IgA and IgM levels (p < 0.05) in patients with an intact nervous system. Neurological involvement in pSS, be it central or peripheral, is not a rare finding. A careful clinical neurological evaluation, combined with a multiplicity of instrumental investigations, is recommended in the global assessment of pSS patients.

Abstract
A significant percentage of patients taking nonsteroidal anti-inflammatory drugs (NSAIDs) experience some type of adverse gastrointestinal symptoms, lesions of the gastroduodenal tract being clinically the most relevant. NSAIDs cause gastrointestinal damage by 2 independent mechanisms: a topical effect, which is pH and pKa related, and a systemic effect mediated by cyclooxygenase (COX) inhibition with a reduction in prostaglandin synthesis. Using endoscopy, gastroduodenal lesions identified include subepithelial haemorrhages, erosions and ulcers. The prevalence of ulceration in NSAID users has been reported as being between 14 and 31% with a 2-fold higher frequency of gastric ulcers compared with duodenal ulcers. Among the strategies used to decrease the risk of ulcer development are: (i) the use of analgesics other than NSAIDs; (ii) use of the lowest possible dosage of NSAID; (iii) the use of a COX-2 selective NSAID; (iv) the use of low doses of corticosteroids instead of NSAIDs; (v) avoidance of concomitant use of NSAIDs and corticosteroids; and (vi) use of preventive therapy. In an attempt to reduce the incidence of NSAID-induced gastrointestinal lesions, the following approaches have been proposed: (i) use of the prostaglandin analogue misoprostol, which is an antiulcer drug which has been proven to be as effective in the prevention of NSAID-induced gastric and duodenal ulcers as in the reduction of serious upper gastrointestinal complications; (ii) histamine H2 receptor antagonists (H2 antagonists), e.g. ranitidine, cimetidine and famotidine, which are useful in the prevention of NSAID-induced duodenal ulcers during long term treatment, but not in the prevention of NSAID-induced gastric ulcers; (iii) proton pump inhibitors, e.g omeprazole, and pantoprazole, whose efficacy in preventing NSAID-associated ulcers has been recently demonstrated; and (iv) barrier agents, e.g. sucralfate, which cannot be recommended as prophylactic agents to prevent NSAID-induced gastropathy. The first step in the treatment of NSAID-associated ulcers lies in a reduction in the dosage of the NSAID or discontinuation of the drug. If NSAID treatment cannot be withdrawn, a proton pump inhibitor appears to be the most effective treatment in healing ulcers, accelerating the slow healing observed with H2 antagonists.

Abstract
In the period 1987-1997 6 patients with Hürthle cell carcinomas and 4 patients with Hürthle cell adenomas underwent primary surgical treatment (8.1% of all thyroid carcinomas). The diagnosis of Hürthle cell tumor was based on the presence of more then 75% Hürthle cells and the malignity on capsular or/and vascular invasion. All the patients with Hürthle cell cancer underwent total thyroidectomy, in three cases with Hürthle cell adenoma thyroid lobectomy was performed and in one case total thyroidectomy. Follow-up time ranged from 1 to 8 years after surgery (mean 4.5 years). There was no death and no recurrence. The Authors have studied the nuclear DNA content in Hürthle cell tumors: 3 adenomas were euploid and 1 was aneuploid, 4 carcinomas were aneuploid and 2 were euploid. The results in Authors' study of the DNA content and nuclear DNA ploidy are not uniformly consistent enough to allow a distinction between benign and malignant neoplasms and to evaluate the prognosis, but the number of patients and the follow up are still too limited.

Abstract
Our objective was to identify nuclear calreticulin-binding protein(s) and investigate whether there is a correlation between presence of autoantibodies against calreticulin and calreticulin-binding protein(s) in the sera of patients suffering from systemic lupus erythematosus (SLE). The ligand overlay procedure using digoxigenin-labelled calreticulin was used to identify a calreticulin-binding protein in the nuclear fraction of bovine brain. Fractionation of the nuclear components was used to localize the major positive calreticulin-binding protein. The protein was partially purified using hydroxylapatitie chromatography and subjected to NH2-amino acid sequence analysis. Immunoblots using the sera of SLE patients were then carried out on calreticulin and the calreticulin-binding protein. The calreticulin-binding protein present in the nucleoplasm was identified as histone H1. Approximately 62% (26/42) patients with SLE had IgG antibodies directed against H1 whereas the sera of healthy individuals did not react with the antigen; 36% of patients with SLE had both anti-calreticulin and anti-histone H1 antibodies. Phosphorylation of the latter protein did not alter its immunoreactivity. These findings demonstrate that the concomitant presence of autoantibodies directed against both calreticulin and histone H1 occurs frequently in patients with SLE and may help shed some light on the mechanisms which bring about the autoimmune response.

Abstract
We used brain single-photon emission tomography (SPET) to detect hypoperfused areas in 15 consecutive Behçet syndrome patients. Five were suspected of having neuro-Behçet syndrome, having at least one neurological symptom. For these patients, SPET was performed within 1 month of the onset of nervous system involvement. The 15 patients fulfilled the criteria of the International Study Group for Behçet syndrome. Neurological assessment and SPET were complemented by EEG in all five patients with suspected neuro-Behçet syndrome and by magnetic resonance imaging in three. Brain SPET detected hypoperfused regions in all five neurological patients; EEG showed abnormalities in three. Magnetic resonance imaging was normal in the three patients in whom it was performed. SPET was negative in all patients without neurological involvement and 20 healthy controls. SPET detected a reduction in brain blood flow in early neuro-Behçet syndrome, but there was no definitive correlation between the hypoperfused brain regions and the clinical features. Further studies are required to evaluate the significance of brain hypoperfusion and the value of SPET in the early diagnosis of neuro-Behçet syndrome.

Abstract
Glucocorticosteroids (GCS) are potent anti-inflammatory and immunosuppressive agents widely used in the treatment of many medical conditions, but their mechanism of action is not yet fully understood. Some of the anti-inflammatory effects of GCS have been attributed to the synthesis of lipocortins, whereas the immunosuppressive effects are thought to be mediated through the inhibition of several immune functions through a down-regulation of cytokine gene expression. Another important mechanism of action of GCS may relate to their ability to interfere with the phenomena of adhesion and migration of inflammatory cells. In this study, the direct effects of GCS on lymphocyte adhesion capacity in vitro were investigated. We demonstrate that GCS inhibit lymphocyte adhesion to endothelium through the down-modulation of lymphocyte adhesion molecules. We also provide evidence that GCS inhibit cell aggregate formation induced by TCR ligation, which directly correlates with the down-modulation of LFA-1 and CD2, but not LFA-3 or ICAM-1. Such down-modulation was paralleled by a decrease in the steady state mRNA level of LFA-1 and CD2 gene products, which suggests a direct GCS control of the expression of these genes. Finally, we show that GCS effects are mediated through the GCS receptor, since they can be completely reversed by the GCS-R antagonist RU-486. This study supports the concept that some of the immunosuppressive and anti-inflammatory effects of GCS are likely to be exerted by the inhibition of adhesion-dependent lymphocyte functions.

Abstract
The diagnosis of central nervous system (CNS) involvement appears to be a major problem in systemic lupus erythematosus (SLE), especially when the clinical signs are non-specific or neuroimaging is unremarkable. Two SLE patients with mild neuropsychiatric manifestations were studied with magnetic resonance imaging (MRI), single photon emission tomography (SPET) and localized proton magnetic resonance spectroscopy (H-1 MRS). MRI was normal in both patients. SPET revealed areas of hypoperfusion in both patients. H-1 MRS demonstrated metabolic abnormalities in the regions corresponding to the hypoperfused areas. A correlation between H-1 MRS and SPET was noted: patients with mild neuropsychiatric SLE may have disturbances evident on SPET and H-1 MRS in the presence of normal anatomy on MRI, suggesting that CNS involvement in SLE has very strong physiological and neurometabolic components in individual patients.

Abstract
NSAID-induced gastropathy is the most frequent side effect due to NSAID use. The resulting clinical event is usually of little significance and only in a small percentage of cases results in serious side effects. Nevertheless, the large worldwide use of NSAIDs makes, even a rare side effect, numerically consistent. The pathogenesis of NSAID-induced gastropathy is related to two main mechanisms: an initial topical effect which is pH dependent and a systemic effect which is, more slowly developing, and mainly correlated to the inhibition of prostaglandin synthesis. The therapy of NSAID-gastropathy is almost completely identified with the therapy of NSAID ulceration because of its frequent relation to the development of potentially serious complications. In the case of symptomatic ulcer development the first therapeutic step is NSAID suspension and, in such a case all "antiulcer" drugs are efficient. When the NSAID can not be discontinued, omeprazole seems to be the most efficient drug; H2 blockers can promote ulcer healing but at a slower rate; sucralfate shows an efficacy similar to H2 blockers; misoprostol is useful in the prevention of NSAID-gastropathy. However, it is not so efficient in the treatment of established lesions and shows poor efficacy in the reduction of dyspeptic symptoms. For each one of these drugs it is necessary to obtain further data.

Abstract
OBJECTIVE To determine the frequency and relative risk of bronchial hyperreactivity to methacholine in systemic sclerosis patients with or without associated Sjögren's syndrome. METHODS A prospective study of 56 patients with systemic sclerosis (42 with the diffuse and 14 with the limited variant; 24 with associated Sjögren's syndrome), 57 with primary Sjögren's syndrome, and 61 healthy controls. RESULTS Bronchial hyperreactivity (BH) was present in 6.5% of the healthy controls, 25% of the systemic sclerosis patients without associated Sjögren's syndrome, 42.2% of those with primary Sjögren's syndrome, and in 50% of those with systemic sclerosis with associated Sjögren's syndrome. The presence of BH did not correlate with age, disease duration, chest radiograph abnormalities, respiratory, and immunological data. The subgroup of subjects with the limited variant of systemic sclerosis more frequently had associated BH than did those with the diffuse variant of the disease; coexisting Sjögren's syndrome further increased this frequency. CONCLUSIONS In agreement with previous studies, we have confirmed the high prevalence of bronchial hyperreactivity in primary Sjögren's syndrome; systemic sclerosis likewise appears to be associated with an increased frequency of bronchial hyperreactivity compared with healthy control subjects. There is evidence also that the coexistence of Sjögren's syndrome and systemic sclerosis further increases the frequency and the calculated relative risk of developing bronchial hyperreactivity.

Abstract
To evaluate the potential for adenovirus-mediated central nervous system (CNS) gene transfer, the replication deficient recombinant adenovirus vectors Ad.RSV beta gal (coding for beta-galactosidase) and Ad-alpha 1AT (coding for human alpha 1-antitrypsin) were administered to the lateral ventricle of rats. Ad.RSV beta gal transferred beta-galactosidase to ependymal cells lining the ventricles whereas Ad-alpha 1AT mediated alpha 1-antitrypsin secretion into the cerebral spinal fluid for 1 week. These observations, together with beta-galactosidase activity in the globus pallidus and substantia nigra following stereotactic administration of Ad.RSV beta gal to the globus pallidus, suggest that adenovirus vectors will be useful for CNS gene therapy.

Abstract
Based on the knowledge that expression of the cystic fibrosis transmembrane conductance regulator (CFTR) gene can be modulated at the transcriptional level, and that the CFTR gene promoter contains sequences homologous to elements in other promoters that respond to tumor necrosis factor-alpha (TNF), we evaluated the hypothesis that TNF might modulate CFTR gene expression in epithelial cells. Studies with HT-29 cells, a colon epithelium-derived tumor cell line known to express the CFTR gene, demonstrated that TNF downregulated CFTR mRNA transcript levels in a dose- and time-dependent fashion. Interestingly, nuclear run-on analyses demonstrated that TNF did not affect the rate of transcription of CFTR gene, but exposure of the cells to TNF did modify the stability of CFTR mRNA transcripts, resulting in a mRNA half-life that was reduced to 65% of the resting level. These observations suggest that CFTR gene expression can be modulated by TNF, at least in part, at the posttranscriptional level.

Abstract
Thirty-six patients with primary Sjögren's syndrome (pSS) and 60 healthy volunteers underwent provocative bronchial testing with aerosolized dosed methacholine. On the average, pulmonary functions tests performed before bronchial testing were normal. However, 18/36 patients (50%) had bronchial hyper-responsiveness (BH), an incidence higher that that found in our control population (6.6%). No difference between BH and normally responsive patients was found in the duration of disease, immunological abnormalities or symptoms, and only the FEF50 was significantly lower in the BH group. It is therefore hypothesized that in pSS bronchial hyper-responsiveness may be due to lymphocytic inflammation and an alteration in secretion secondary to gland damage.

Abstract
SAPHO has recently been proposed as an acronym to identify a syndrome characterized by synovitis, acne, pustulosis, hyperostosis and osteomyelitis. Several authors have, however, found that this rare condition may even occur without cutaneous manifestations. The work reported here presents the case of a 43-year-old male with skeletal involvement alone. An in-depth study of the patient revealed the arthro-osteitic pattern typical of the SAPHO syndrome. In agreement with previous reports, these data confirm that the present clinical picture of hyperostosis and osteitis, even without cutaneous involvement, is nonetheless related to the SAPHO syndrome.
