Background: Traumatic brain injury (TBI) in the elderly is a noteworthy pathology due to the exponential increase in population age, and the effects of antiplatelet and anticoagulation on patients' outcomes are still a matter of dispute. The aim of the present study was to evaluate the impact of various antithrombotic agents on patients with mild TBI, focusing on the risk of intracranial bleeding (ICH) and length of hospitalization (LOS)., Methods: A retrospective analysis was conducted, including patients with a diagnosis of TBI admitted to the Emergency Department between 2021 and 2022. Patients were classified according to the concurrent antithrombotic therapy as aspirin (ASA), antiplatelets, direct oral anticoagulants (DOACs), and low-molecular-weight heparin (LMWH). The primary outcome was the ICH occurrence, while the secondary outcome was the LOS. The statistical analysis was performed via logistic regression models in R and STATA 13.1 software. Fisher's exact test was used for the statistical significance., Results: 267 patients with mild TBI were included; 148 were not on antithrombotic agents, 43 were on aspirin, 33 on DOACs, 5 on LMWH, 22 on antiplatelets, and 16 on VKA. Out of the total, 9 patients experienced ICH, none of which were on DOACs, LMWH, or VKA, but 4-out of 65-were on antiplatelets, and 5-out of 148-were not on antithrombotic therapies. Patients not on antithrombotic therapy had the shortest LOS at 0.46 days, while those on VKA had the longest LOS at 1.19 days; similar trends were observed for patients on DOAC and LMWH., Conclusions: The results reveal that TBI patients on anticoagulants/antiplatelets had longer hospital stays compared with those on aspirin alone. Notably, VKA was the strongest predictor for an extended LOS. Regarding ICH, patients taking only aspirin were twice as likely to experience bleeding compared with those on anticoagulants/antiplatelets. However, to achieve statistically significant evidence, further research with a larger cohort of patients is needed.

Background: Intravenous iloprost has been widely used for the treatment of systemic sclerosis peripheral vasculopathy. No agreement has been found on the regimen and the dosage of intravenous iloprost in different scleroderma subset conditions. This study aimed to evaluate the modalities of intravenous iloprost administration within a large cohort of systemic sclerosis patients from the SPRING Registry and to identify any associated clinical-demographic, instrumental or therapeutic data., Patients and Methods: Data of systemic sclerosis patients treated with intravenous iloprost for at least 1 year (case group) were retrospectively analyzed, including different timing and duration of intravenous iloprost session, and compared with those of untreated patients (control group)., Results: Out of 1895 analyzed patients, 937 (49%) received intravenous iloprost treatment, while 958 (51%) were assigned to the control group. Among cases, about 70% were treated every 4 weeks, 24% with an interval of more than 4 weeks, and only 6% of less than 4 weeks. Most patients receiving the treatment every 4 weeks, or less, underwent infusion cycle for 1 day only, while if it was scheduled with an interval of more than 4 weeks, a total number of 5 consecutive days of infusions was the preferred regimen. The comparison between the two groups revealed that patients treated with intravenous iloprost had a higher frequency of DUs (p < 0.001), pitting scars (p < 0.001), diffuse cutaneous involvement (p < 0.001), interstitial lung disease (p < 0.002), as well as higher rates of anti-topoisomerase I, " late " scleroderma pattern at nailfold videocapillaroscopy. These findings were confirmed by multivariate analysis., Conclusion: Our data provide a picture on the Italian use of intravenous iloprost among systemic sclerosis patients and showed that it was usually employed in patients with a more aggressive spectrum of the disease. The disparity of intravenous iloprost treatment strategies in the different centers suggests the need of a rational therapeutical approach based on the clinical characteristics of different patients' subsets., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Objective: To describe demographic, clinical and laboratory features of systemic sclerosis sine scleroderma (ssSSc) in a large multicentre systemic sclerosis (SSc) cohort., Methods: Data involving 1808 SSc patients from Italian Systemic sclerosis PRogression INvestiGation registry were collected. The ssSSc was defined by the absence of any cutaneous sclerosis and/or puffy fingers. Clinical and serological features of ssSSc were compared with limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subsets., Results: Among patients with SSc, only 61 (3.4%) were classified as having ssSSc (F/M=19/1). Time from Raynaud's phenomenon (RP) onset to diagnosis was longer in ssSSc (3 years, IQR 1-16.5) than lcSSc (2 years, IQR 0-7), and dcSSc (1 year, IQR 0-3) (p<0.001). Clinical ssSSc phenotype was comparable to lcSSc, except for digital pitting scars (DPS) (19.7% vs 42%, p=0.01), but significantly milder than dcSSc, particularly for digital ulcers (DU) (6.6% vs 35.7%, p<0.001), oesophagus (46.2% vs 63.5%, p=0.009), lung (mean diffusion capacity for carbon monoxide 72.2±19.6 vs 62.4±22.8, p=0.009; mean forced vital capacity 105.6±21.7 vs 89.2±20.9, p<0.001) and major videocapillaroscopic alterations (late pattern 8.6% vs 47.6%, p<0.001). Moreover, in ssSSc the percentages of anticentromere and antitopoisomerase were comparable to lcSSc (40% and 18.3% vs 36.7% and 26.6%), but divergent respect to dcSSc (8.6% and 67.4%, p<0.001)., Conclusion: The ssSSc is a quite rare disease variant characterised by clinico-serological features comparable to lcSSc, but significantly different from dcSSc. Overall, longer RP duration, low percentages of DPS and peripheral microvascular abnormalities, and increased anti-centromere seropositivity distinguish ssSSc. Further investigations based on national registries might provide useful insights on the actual relevance of the ssSSc within the scleroderma spectrum., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: Systemic sclerosis (SSc) is characterized by a complex etiopathogenesis encompassing both host genetic and environmental -infectious/toxic- factors responsible for altered fibrogenesis and diffuse microangiopathy. A wide spectrum of clinical phenotypes may be observed in patients' populations from different geographical areas. We investigated the prevalence of specific clinical and serological phenotypes in patients with definite SSc enrolled at tertiary referral centres in different Italian geographical macro-areas. The observed findings were compared with those reported in the world literature., Materials and Methods: The clinical features of 1538 patients (161 M, 10.5%; mean age 59.8 ± 26.9 yrs.; mean disease duration 8.9 ± 7.7 yrs) with definite SSc recruited in 38 tertiary referral centres of the SPRING (Systemic sclerosis Progression INvestiGation Group) registry promoted by Italian Society of Rheumatology (SIR) were obtained and clustered according to Italian geographical macroareas., Results: Patients living in Southern Italy were characterized by more severe clinical and/or serological SSc phenotypes compared to those in Northern and Central Italy; namely, they show increased percentages of diffuse cutaneous SSc, digital ulcers, sicca syndrome, muscle involvement, arthritis, cardiopulmonary symptoms, interstitial lung involvement at HRCT, as well increased prevalence of serum anti-Scl70 autoantibodies. In the same SSc population immunusppressive drugs were frequently employed. The review of the literature underlined the geographical heterogeneity of SSc phenotypes, even if the observed findings are scarcely comparable due to the variability of methodological approaches., Conclusion: The phenotypical differences among SSc patients' subgroups from Italian macro-areas might be correlated to genetic/environmental co-factors, and possibly to a not equally distributed national network of information and healthcare facilities., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Anti-mitochondrial antibodies (AMA) are directed against the E2 subunits of the 2-oxo acid dehydrogenase complexes (PDC-E2) and are the typical biomarkers of primary biliary cholangitis (PBC), being present in 90-95% of patients, with increasing sensitivity at increasing titers. Albeit being highly specific for PBC diagnosis, AMA can be detected in less than 1% of healthy subjects, and thus the management subjects with no sign or symptom of liver disease is still a challenge and data concerning clinical risk of developing PBC in this subgroup of patients are controversial. Moreover, AMA can also be detected in patients affected by overlap syndrome, as well as hepatic diseases (i.e., NASH and viral hepatitis), while the association with autoimmune diseases, in particular Sjögren's syndrome, systemic sclerosis, and systemic lupus erythematosus, is well established. Furthermore, new associations are being identified with inflammatory myositis and heart disease. AMA are directed towards the pyruvate dehydrogenase multi enzyme complex (PDC-E2) subunit, which represents an epithelial specific autoantigen for PBC. This review focuses on the main characteristics of AMA, their association with autoimmune diseases and liver diseases., (© 2021.

Purpose: The objective of this systematic review was to critically assess the available literature on deep learning (DL) and radiomics applied to the Liver Imaging Reporting and Data System (LI-RADS) in terms of 1) automatic LI-RADS classification of liver nodules; 2) the contribution of DL and radiomics to human evaluation in the classification of liver nodules following LI-RADS protocol., Materials and Methods: A literature search was conducted to identify original research studies published up to April 2021. The inclusion criteria were: English language, focus on computed tomography (CT) and/or magnetic resonance (MR) with specified number of patients and lesions, adoption of LI-RADS classification for the detected hepatic lesions, and application of AI in the classification of liver nodules. Review articles, conference papers, editorials and commentaries, animal studies or studies with absence of AI and/or LI-RADS were excluded. After screening 221 articles, 11 studies were included in this review., Results: All the included studies proved that DL and radiomics have high performances in liver nodules classification, sometimes similar or better than human evaluation. The best performances of DL was an AUC of 0.95 on MR and the best performance of radiomics was AUC of 0.98 either on CT and MR, while the lower ones were respectively AUC of 0.63 either on CT and MR for DL and AUC of 0.70 on CT for radiomics., Conclusion: DL and radiomics could be a useful tool in assisting radiologists in the diagnosis and classification of liver nodules according to LI-RADS., (Copyright © 2022 Elsevier B.V.

The concern about the offspring's health is one of the reasons for a reduced family size of women with rheumatic diseases (RD). Increased risk of autoimmune diseases (AD) and neurodevelopmental disorders (ND) has been reported in children born to patients with RD. Within a nationwide survey about reproductive issues of women with RD, we aimed at exploring the long-term outcome of their children. By surveying 398 patients who received their diagnosis of RD during childbearing age (before the age of 45), information about the offspring were obtained from 230 women who declared to have had children. A total of 148 (64.3%) patients were affected by connective tissue diseases (CTD) and 82 (35.7%) by chronic arthritis. Data on 299 children (156 males, 52.1%; mean age at the time of interview 17.1 ± 9.7 years) were collected. Twelve children (4.0%), who were born to patients with CTD in 75% of the cases, were affected by AD (8 cases of celiac disease). Eleven children had a certified diagnosis of ND (3.6%; 6 cases of learning disabilities); 9 of them were born to mothers with CTD (5 after maternal diagnosis). No association was found between ND and prenatal exposure to either maternal autoantibodies or anti-rheumatic drugs. Absolute numbers of offspring affected by AD and ND were low in a multicentre cohort of Italian women with RD. This information can be helpful for the counselling about reproductive issues, as the health outcomes of the offspring might not be an issue which discourage women with RD from having children., (© 2021.

Objective: There is still a great deal to learn about the influence of sex in systemic sclerosis (SSc). In this respect, national registries provide large and homogeneous patient cohorts for analytical studies. We therefore investigated a wide-ranging and well-characterized SSc series with the aim of identifying sex differences in disease expression, with a special focus on demographic, clinical, and serological characteristics., Methods: A multicenter SSc cohort of 2281 patients, including 247 men, was recruited in the Italian Systemic sclerosis PRogression INvestiGation (SPRING) registry. Demographic data, disease manifestations, serological profile, and internal organ involvement were compared., Results: The overall female/male ratio was 8.2:1. Female/male ratios for limited cutaneous SSc, diffuse cutaneous SSc, and SSc sine scleroderma subsets were 8.7:1, 4.9:1, and 10.7:1, respectively. A shorter time from onset of Raynaud phenomenon to SSc diagnosis, an increased prevalence of the diffuse cutaneous subset, renal crisis, and digital ulcers were found in males, whereas a significantly higher percentage of sicca syndrome, serum antinuclear antibodies, antiextractable nuclear antigens, anti-La/SSB, and anticentromere protein B was detected in the female group. Males exhibited lower left ventricular ejection fraction, as well as higher prevalence of conduction blocks, arrhythmias, ground glass, and honeycombing. Moreover, forced vital capacity and total lung capacity were medially lower in men than in women. Finally, males were more frequently treated with immunosuppressive drugs., Conclusion: Our study further supports the presence of several sex-related differences in patients with SSc. These differences were pronounced in the severity of cutaneous, peripheral vascular, and cardiopulmonary involvement for male patients, whereas an increased prevalence of sicca syndrome and a specific autoantibody profile characterized the female sex., (© 2022 by the Journal of Rheumatology.)

Introduction: Identifying SARS-CoV-2 patients at higher risk of mortality is crucial in the management of a pandemic. Artificial intelligence techniques allow one to analyze large amounts of data to find hidden patterns. We aimed to develop and validate a mortality score at admission for COVID-19 based on high-level machine learning., Material and Methods: We conducted a retrospective cohort study on hospitalized adult COVID-19 patients between March and December 2020. The primary outcome was in-hospital mortality. A machine learning approach based on vital parameters, laboratory values and demographic features was applied to develop different models. Then, a feature importance analysis was performed to reduce the number of variables included in the model, to develop a risk score with good overall performance, that was finally evaluated in terms of discrimination and calibration capabilities. All results underwent cross-validation., Results: 1,135 consecutive patients (median age 70 years, 64% male) were enrolled, 48 patients were excluded, and the cohort was randomly divided into training (760) and test (327) groups. During hospitalization, 251 (22%) patients died. After feature selection, the best performing classifier was random forest (AUC 0.88 ±0.03). Based on the relative importance of each variable, a pragmatic score was developed, showing good performances (AUC 0.85 ±0.025), and three levels were defined that correlated well with in-hospital mortality., Conclusions: Machine learning techniques were applied in order to develop an accurate in-hospital mortality risk score for COVID-19 based on ten variables. The application of the proposed score has utility in clinical settings to guide the management and prognostication of COVID-19 patients., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia & Banach.)

Objective: Autoimmune systemic diseases (ASD) represent a predisposing condition to COVID-19. Our prospective, observational multicenter telephone survey study aimed to investigate the prevalence, prognostic factors, and outcomes of COVID-19 in Italian ASD patients., Methods: The study included 3,918 ASD pts (815 M, 3103 F; mean age 59±12SD years) consecutively recruited between March 2020 and May 2021 at the 36 referral centers of COVID-19 and ASD Italian Study Group. The possible development of COVID-19 was recorded by means of a telephone survey using a standardized symptom assessment questionnaire., Results: ASD patients showed a significantly higher prevalence of COVID-19 (8.37% vs. 6.49%; p<0.0001) but a death rate statistically comparable to the Italian general population (3.65% vs. 2.95%). Among the 328 ASD patients developing COVID-19, 17% needed hospitalization, while mild-moderate manifestations were observed in 83% of cases. Moreover, 12/57 hospitalized patients died due to severe interstitial pneumonia and/or cardiovascular events; systemic sclerosis (SSc) patients showed a significantly higher COVID-19-related death rate compared to the general population (6.29% vs. 2.95%; p=0.018). Major adverse prognostic factors to develop COVID-19 were: older age, male gender, SSc, pre-existing ASD-related interstitial lung involvement, and long-term steroid treatment. Of note, patients treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) showed a significantly lower prevalence of COVID-19 compared to those without (3.58% vs. 46.99%; p=0.000), as well as the SSc patients treated with low dose aspirin (with 5.57% vs. without 27.84%; p=0.000)., Conclusion: During the first three pandemic waves, ASD patients showed a death rate comparable to the general population despite the significantly higher prevalence of COVID-19. A significantly increased COVID-19- related mortality was recorded in only SSc patients' subgroup, possibly favored by preexisting lung fibrosis. Moreover, ongoing long-term treatment with csDMARDs in ASD might usefully contribute to the generally positive outcomes of this frail patients' population., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background and Aims: Treatment options for PsA, following non-steroidal anti-inflammatory drugs (NSAIDs), include conventional synthetic disease modifying anti-rheumatic drugs (csDMARDS), particularly methotrexate (MTX). The present study was performed to determine the non-adherence and discontinuation rates of different methotrexate (MTX) formulations in psoriatic arthritis (PsA)., Approach and Results: We performed a retrospective-cohort study on patients with PsA identified by disease-specific code in the administrative-health-databases of a Northern Italian region (Lombardy) between 2004 and 2015. Subjects were defined as non-adherent if less than 80% of the prescribed MTX dose was taken based on the time between each prescription. Discontinuation rates were calculated using the time between the first and the last MTX prescription over an observation period of 120 months. Among 8952 patients with PsA, 33% were treated with MTX (mean dosage 10 mg/week ± 2.5 mg standard deviation), more frequently (59%) in its parenteral formulation at a 10 mg weekly dosage (35%). Oral glucocorticoids were prescribed to 21% of patients, while non-steroidal anti-inflammatory drugs to 45%. Approximately 37% of patients with PsA were defined as non-adherent to MTX, with the oral formulation associated with an increased risk of non-adherence (hazard ratio 2.08, 95% confidence interval 1.84-2.35, p < 0.001) compared with parenteral 10-15 mg weekly doses. Oral MTX was discontinued in 52% of cases without a significantly increased risk of discontinuation compared to parenteral formulations which, at higher dosages, had a more favorable retention rate., Conclusion: Oral MTX formulation is associated with a 2-fold risk of non-adherence compared to MTX parenteral route in PsA., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 The Authors.)

Background: The Covid-19 pandemic may have a deleterious impact on patients with autoimmune systemic diseases (ASD) due to their deep immune-system alterations., Objective: This study aims to investigate the prevalence of symptomatic Covid-19 and its correlations with both organ involvement and ongoing treatments in a large series of Italian ASD patients during the first wave of pandemic., Methods: Our multicenter telephone 6-week survey included 3,029 unselected ASD patients enrolled at 36 tertiary referral centers of northern, central, and southern Italian macro-areas with different diffusion of the pandemic. Symptomatic SARS-CoV-2 infection was classified as definite Covid-19 (presence of symptoms plus positive oral/nasopharyngeal swabs) or highly suspected Covid-19 (highly suggestive symptoms, in the absence of a swab testing)., Results: A significantly higher prevalence of definite plus highly suspected Covid-19 compared to the Italian general population was detected in the whole ASD series (p=.000), as well as in patients from the three macro-areas (p=.000 in all). Statistically higher prevalence of Covid-19 was also found in connective tissue diseases compared to chronic arthritis subgroup (p=.000) and in ASD patients with pre-existing interstitial lung involvement (p=.000). Patients treated with either conventional disease-modifying anti-rheumatic drugs (DMARDs) and/or biological DMARDs showed a significantly lower prevalence of Covid-19 (p=.000 in both). Finally, scleroderma patients undergoing low-dose aspirin showed a significantly lower rate of Covid-19 compared to those without (p=0.003)., Conclusion: The higher prevalence of Covid-19 in ASD patients, along with the significant correlations with important clinical features and therapeutic regimens, suggests the need to develop targeted prevention/management strategies during the current pandemic wave., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Objectives: The study aimed to determine the prevalence of rheumatoid factor (RF) and anti-citrullinated peptides (ACPA), to estimate the association with hepatitis B (HBV) or C (HCV) virus infections and the 15-year risk of developing RA in a large cohort from a Northern Italian region., Methods: In 1998, 15,907 subjects between the ages of 18 and 75 were randomly selected 1:4 for HBV and HCV testing; more recently, we tested a subgroup of sera for RF (n=2196) and ACPA (n=2525). Administrative databases were searched after 15 years for incident RA diagnoses occurring between 1998 and 2013., Results: RF was positive in 8.1% of cases with 10% of RF-positive subjects having HBsAg (p=0.004) and 9% anti-HCV. ACPA were detected in 4.8% of subjects with 5% of the ACPA-positive subjects having HBsAg and 5.9% anti-HCV. Older subjects had higher positivity rates for both RF and ACPA. HBsAg and anti-HCV were detected in 5.5% and 4.3% of sera, respectively. Over 15 years, 10 RA cases were recorded (9 women, median age at diagnosis 52 years) with RF previously positive in 2/10 and ACPA in 5/10 cases. RF and ACPA were associated with relative risks for developing RA of 5.7 (adjusted for HBsAg status; 95% CI 1.2-26.3) and 13.2 (95% CI 3.8-46.3), respectively., Conclusions: Our data in a large cohort from an unselected general population confirm a higher risk of RA development associated with ACPA compared to RF. HBV exposure correlates with RF but not with ACPA positivity.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected 189 000 people in Italy, with more than 25 000 deaths. Several predictive factors of mortality have been identified; however, none has been validated in patients presenting with mild disease., Methods: Patients with a diagnosis of interstitial pneumonia caused by SARS-CoV-2, presenting with mild symptoms, and requiring hospitalization in a non-intensive care unit with known discharge status were prospectively collected and retrospectively analysed. Demographical, clinical and biochemical parameters were recorded, as need for non-invasive mechanical ventilation and admission in intensive care unit. Univariate and multivariate logistic regression analyses were used to identify independent predictors of death., Results: Between 28 February and 10 April 2020, 229 consecutive patients were included in the study cohort; the majority were males with a mean age of 60 years. 54% of patients had at least one comorbidity, with hypertension being the most commonly represented, followed by diabetes mellitus. 196 patients were discharged after a mean of 9 days, while 14.4% died during hospitalization because of respiratory failure. Age higher than 75 years, low platelet count (<150 × 10 3 /mm 3 ) and higher ferritin levels (>750 ng/mL) were independent predictors of death. Comorbidities were not independently associated with in-hospital mortality., Conclusions: In-hospital mortality of patients with COVID-19 presenting with mild symptoms is high and is associated with older age, platelet count and ferritin levels. Identifying early predictors of outcome can be useful in the clinical practice to better stratify and manage patients with COVID-19., (© 2020 Stichting European Society for Clinical Investigation Journal Foundation.)

Objectives: Systemic sclerosis (SSc) is a severe multiple-organ disease characterised by unpredictable clinical course, inadequate response to treatment, and poor prognosis. National SSc registries may provide large and representative patients cohorts required for descriptive and prognostic studies. Therefore, the Italian Society for Rheumatology promoted the registry SPRING (Systemic sclerosis Progression INvestiGation)., Methods: The SPRING is a multi-centre rheumatological cohort study encompassing the wide scleroderma spectrum, namely the primary Raynaud's phenomenon (pRP), suspected secondary RP, Very Early Diagnosis of Systemic Sclerosis (VEDOSS), and definite SSc. Here we describe the demographic and clinical characteristics of a population of 2,028 Italian patients at the initial phase of enrolment, mainly focusing on the cohort of 1,538 patients with definite SSc., Results: Definite SSc showed a significantly higher prevalence of digital ulcers, capillaroscopic 'late' pattern, oesophageal and cardio-pulmonary involvement compared to VEDOSS, as expected on the basis of the followed classification criteria. The in-depth analysis of definite SSc revealed that male gender, diffuse cutaneous subset, and anti-Scl70 seropositivity were significantly associated with increased prevalence of the most harmful disease manifestations. Similarly, patients with very short RP duration (≤1 year) at SSc diagnosis showed a statistically increased prevalence of unfavourable clinico-serological features., Conclusions: Nationwide registries with suitable subsetting of patients and follow-up studies since the prodromal phase of the disease may give us valuable insights into the SSc natural history and main prognostic factors.

Background: There is no agreement on the prevalence of anti-phospholipid antibodies (aPLs) and the correlation with atherosclerosis and cardiovascular (CV) events in the general population., Methods: We performed a cross-sectional study on 1712 randomly enrolled subjects from a Northern Italian city to investigate the presence of aPLs and the association with subclinical atherosclerosis (using the carotid artery intima media thickness measured as inter-adventitia common carotid artery diameters - ICCAD) and retrospectively collected CV factors and events (i.e. acute myocardial infarction, stroke, and peripheral obliterans arterial vasculopathy) using physician-assisted questionnaires. We tested serum IgG, IgM, and IgA anti-cardiolipin, anti-beta2glycoprotein I (aGPI), and anti-phosphatidylserine-prothrombin antibodies., Results: Positive aPLs were found in 15.1% of the subjects, with no differences between sex but with higher rates in older subjects. Carotid subclinical atherosclerosis was more frequent in aPL positive subjects; more specifically, aGPI IgA were associated with higher ICCAD average (adjusted beta 0.51, 95% confidence interval (CI)0.17-0.84; p = 0.003). A positive history of CV events was also more frequent in aPL positive subjects (odds ratio (OR) 1.67, 95%CI 1.08-2.54; p = 0.012), particularly peripheral obliterans arterial vasculopathy (OR 2.02; 95%CI 1.14-3.57; p = 0.015). Among subjects with a Framingham risk score >20, and/or diabetes, and/or body mass index >35 kg/m 2 , aPL positivity was associated to the highest risk of CV events (OR 2.52, 95%CI 1.24-5.11; p = 0.011)., Conclusions: APL prevalence in the general population is higher than previously reported. CV events and subclinical atherosclerosis are more frequent in the presence of aPL, particularly when a high CV risk coexists., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Objective: The reproductive choices of women affected by rheumatic diseases (RD) can be influenced by several factors, including the quality of physician-patient communication. We conducted a survey on reproductive issues aiming at exploring the unmet needs of women with RD during childbearing age., Methods: We administered 65 multiple-choice and 12 open-answer questions about pregnancy counselling, contraception, use of drugs during pregnancy and other women reproductive issues to 477 consecutive women with RD aged 18-55 years followed-up in 24 rheumatology centres in Italy. Analysis was restricted to 398 patients who received their diagnosis of RD before the age of 45. According to the RD diagnosis, patients were subdivided into 2 groups: connective tissue diseases (n = 249) and chronic arthritis (n = 149)., Results: At the time of interview, women in both groups had a mean age of 40 years. Nearly one third of patients in each group declared not to have received any counselling about either pregnancy desire nor contraception. A smaller family size than desired was reported by nearly 37% of patients, because of concerns related to maternal disease in one fourth of the cases. A "Disease Knowledge Index" (DKI) was created to investigate the degree of patients' information about the implications of their RD on reproductive issues. Having received counselling was associated with higher DKI values and with a positive impact on family planning., Conclusion: Italian women of childbearing age affected by RD reported several unmet needs in their knowledge about reproductive issues. Strategies are needed to implement and facilitate physician-patient communication., (Copyright © 2018. Published by Elsevier Masson SAS.)

To estimate biologic influence on heart failure (HF) risk in rheumatoid arthritis. Retrospective cohort (RECORD Study of Italian Society for Rheumatology) study on administrative healthcare databases. We identified 2527 patients treated with either etanercept (n = 1690) or abatacept (n = 837). HF incidence rate was higher in the abatacept cohort than in the etanercept cohort with a 2.38 (95% CI 1.08-5.27) crude competing risk HR (SHR) for abatacept of developing HF, not confirmed after adjustment for prespecified confounders (SHR 1.43; 95% CI 0.51-3.98). Abatacept, compared to etanercept, is prescribed to patients with a worse cardiovascular profile but does not increase the risk of developing HF, when confounding factors are accounted for.

Type II mixed cryoglobulinemia without evidence of HCV infection but rather with renal involvement has been occasionally described. The pathogenesis of cryoglobulinemic kidney disease is most likely related to immune complex deposition including cryoglobulins, and cryoaggregation after cold exposure could play a pivotal role in clinical expression of cryoglobulinemia. In these cases, acute kidney injury and proteinuria remain the most frequent clinical expression of a cryoglobulinemic glomerulonephritis. Type II cryoglobulinemia with the laboratory finding of both monoclonal and polyclonal cryoglobulins is the most prevalent bio-humoral pattern among HCV-negative phenotypes with renal involvement, while type III cryoglobulinemia with polyclonal Ig is rare. Histological data in renal biopsies support the hypothesis that regardless of the HCV status cryoglobulinemia vasculitis share the same frequent pathological finding of membranoproliferative glomerulonephritides, but other histological patterns have also been observed in a minority of cases. In HCV-negative mixed cryoglobulinaemia, the paraneoplastic origin of the immune dysfunction should be ruled out and sporadic cases have been reported, while there is no cumulative evidence on the prevalence of these tumour-associated manifestations. Moving from the classification criteria and the etiopathogenesis of mixed cryoglobulinaemia, we provide a comprehensive review of the literature on the appearance of the disease with kidney injury in association with malignancies or autoimmune disorders without HCV coexistence.

Spondyloarthritides (SpA) include inflammatory joint diseases with various clinical phenotypes that may also include the axial skeleton and/or entheses. SpA include psoriatic arthritis, reactive arthritis, enteropathic arthritis and ankylosing spondylitis; the latter is frequently associated with extra-articular manifestations, such as uveitis, psoriasis, and inflammatory bowel disease. SpA are associated with the HLA-B27 allele and recognize T cells as key pathogenetic players. In contrast to other rheumatic diseases, SpA affect women and men equally and are not associated with detectable serum autoantibodies. In addition, but opposite to rheumatoid arthritis, SpA are responsive to treatment regimens including IL-23 or IL-17-targeting biologics, yet are virtually unresponsive to steroid treatment. Based on these differences with prototypical autoimmune diseases, such as rheumatoid arthritis or connective tissue diseases, SpA may be better classified among autoinflammatory diseases, with a predominant innate immunity involvement. This would rank SpA closer to gouty arthritis and periodic fevers in the spectrum of rheumatic diseases, as opposed to autoimmune-predominant diseases. We herein provide available literature on risk factors associated with SpA in support of this hypothesis with a specific focus on genetic and environmental factors., (Copyright © 2018 The Authors.

The current approach to treatment of rheumatoid arthritis (RA) includes early and aggressive intervention aiming to reach early and persistent low disease activity and remission. New drugs have improved the therapeutic armamentarium of rheumatologists, providing new options for patients. Beyond these innovations, new evidence has improved the safety of therapies and provided tools for the optimisation of long-term management of RA. This paper reviews the most relevant studies published over the last year in the field of treatment of RA.

Objectives: To verify if tocilizumab (TCZ) is associated with an increased risk of cardiovascular (CV) events compared with etanercept (ETN) in rheumatoid arthritis (RA)., Methods: This is a retrospective cohort study on administrative healthcare databases (AHD) in Italy. Patients were identified using a validated algorithm based on AHD. Exposure to specific drugs was estimated by the drug prescription recorded in the AHD. The occurrence of acute CV events (myocardial infarction, stroke, other CV events) was derived from the hospital discharge forms. The association between TCZ or ETN and CV events was estimated using competing risk models, adjusting for pre-specified confounders., Results: We identified 1,752 subjects with RA, 1,086 treated with ETN and 666 with TCZ. TCZ did not increase the overall risk of acute CV events, even when adjusted for pre-specified confounders (hazard ratio HR 0.95, 95% confidence interval 95%CI 0.54-1.66), specifically of acute myocardial infarction (HR 0.39, 95%CI 0.15-1.06), stroke (HR 1.44, 95%CI 0.24-8.68) or other CV event (1.07, 95%CI 0.59-1.92)., Conclusions: RA patients with TCZ do not have a medium-term excess of CV risk in patients compared with ETN.

Autoimmune liver diseases coexist with rheumatic disorders in approximately 30% of cases and may also share pathogenic mechanisms. Autoimmune liver diseases result from an immune-mediated injury of different tissues, with autoimmune hepatitis (AIH) targeting hepatocytes, and primary biliary cholangitis (PBC) and primary sclerosing cholangitis targeting cholangiocytes. Sjogren syndrome is diagnosed in 7% of AIH cases and serologic autoimmunity profiles are a common laboratory abnormality, particularly in the case of serum antimitochondrial (PBC) or anti-liver kidney microsomal antibodies (AIH). Therapeutic strategies may overlap between rheumatic and autoimmune liver diseases and practitioners should be vigilant in managing bone loss., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Objective: To describe a new immunoprecipitation pattern identified in Italian patients affected by systemic sclerosis (SSc), corresponding to the pyruvate dehydrogenase antigen complex recognized by anti-mitochondrial antibodies (AMA) in primary biliary cholangitis (PBC)., Methods: Autoantibodies in sera from 85 patients with SSc were tested by protein- and RNA-immunoprecipitation. Immunoprecipitation-Western blot was used to determine the identified proteins, and medical records re-evaluated for liver function tests and PBC., Results: In 13/85 (15%) SSc sera, a unique set of 75-50-40-34kD proteins that had not been previously reported, was noted. The four proteins were identified as the proteins X/E3BP, E1α, E1β, and E2/E3 of the pyruvate dehydrogenase antigen complex by immunoprecipitation-Western blot. From clinical record evaluation, 9/13 (69%) SSc patients with this new pattern were positive for AMA by routine indirect immunofluorescence, and 7/13 (54%) had a diagnosis of PBC, while 4/13 (31%) manifested no biochemical signs of cholestasis. Twelve of 13 patients with SSc and AMA by immunoprecipitation have a limited cutaneous form of SSc and anti-centromere antibodies., Conclusions: We describe a pattern of 4 proteins in 15% of SSc patients, identified for the first time by protein-immunoprecipitation. This pattern corresponds to serum AMA against the pyruvate dehydrogenase antigen complex and it must be considered in the interpretation of protein-immunoprecipitation results., (Copyright © 2017 Elsevier B.V.

The sequencing of the human genome is now well recognized as the starting point of personalized medicine. Nonetheless, everyone is unique and can develop different phenotypes of the same disease, despite identical genotypes, as well illustrated by discordant monozygotic twins. To recognize these differences, one of the easiest and most familiar examples of biomarkers capable of identifying and predicting the outcome of patients is represented by serum autoantibodies. In this review, we will describe the concept of personalized medicine and discuss the predictive, prognostic and preventive role of antinuclear antibodies (ANA), anti-citrullinated peptide antibodies (ACPA), rare autoantibodies and anti-drug antibodies (ADA), to evaluate how these can help to identify different disease immune phenotypes and to choose the best option for treating and monitoring rheumatic patients in everyday practice. The importance of ANA resides in the prediction of clinical manifestations in systemic sclerosis and systemic lupus erythematosus and their association with malignancies. ACPA have a predictive role in rheumatoid arthritis, they are associated with the development of a more aggressive disease, extra-articular manifestations and premature mortality in RA patients; moreover, they are capable of predicting therapeutic response. Rare autoantibodies are associated with different disease manifestations and also with a greater incidence of cancer. The determination of ADA levels may be useful in patients where the clinical efficacy of TNF-α inhibitor has dropped, for the assessment of a right management. The resulting scenario supports serum autoantibodies as the cornerstone of personalized medicine in autoimmune diseases.

Sjögren's syndrome is currently considered an "autoimmune epithelitis," as exocrine glands, especially salivary and lacrimal, are progressively destructed by an immune-mediated process associated with specific serum autoantibodies and local lymphocyte infiltrate. Xerostomia remains a key complain in patients with Sjögren's syndrome but should be evaluated also for other causes such as xerogenic medications, followed by radiation and chemotherapy for head and neck cancers, hormone disorders, infections, or other connective tissue diseases. Further, xerophtalmia (also known as dry eye) frequently associated with keratoconjunctivitis sicca cumulatively affects approximately 10-30% of the general population with increasing incidence with age and is more frequently secondary to non-autoimmune diseases. On the other hand, numerous patients with Sjögren's syndrome manifest signs of systemic dryness involving the nose, the trachea, the vagina, and the skin, suggesting that other glands are also affected beyond the exocrine epithelia. Skin involvement in Sjögren's syndrome is relatively common, and various manifestations may be present, in particular xeroderma, eyelid dermatitis, annular erythema, and cutaneous vasculitis. Additional skin non-vasculitic manifestations include livedo reticularis which may occur in the absence of vasculitis, and localized nodular cutaneous amyloidosis possibly representing lymphoproliferative diseases related to Sjögren's syndrome. The treatment of skin and mucosal manifestations in Sjögren's syndrome is similar regardless of the cause, starting from patient education to avoid alcohol and tobacco smoking and to pursue dental hygiene. In conclusion, a strict collaboration between the dermatologist and the rheumatologist is essential in the adequate management of Sjögren's syndrome skin and mucosal manifestations.

Objectives: Inflammatory arthritis needs infectious disease screening before starting a biologic agent, however, few data are known about migrant patients, who represent a peculiar population which requires a multidisciplinary approach among international health specialists and should also be considered by health authorities. For this reason, the Italian and Spanish Societies of Rheumatology (SIR and SER) and Tropical Medicine (SIMET and SEMTSI) promoted a multidisciplinary task force in order to produce specific recommendations about screening and advices to be considered in migrant patients with inflammatory arthritis candidate to receive biological therapy, according to their geographical origin., Methods: The experts provided a prioritised list of research questions and the eligible spectrum of inflammatory arthritis, biologic drugs and infectious disease were defined in order to perform a systematic literature review. A search was made in Medline, Embase and Cochrane library, updated to March 2015. Ubiquitous infections and HBV, HCV, HIV and tuberculosis that are already considered in national and international recommendations, were not included. The strength of each recommendation was determined., Results: The task force members agreed on 7 overarching principles. The risk of reactivation of selected potentially latent infectious disease was addressed in migrants with inflammatory arthritis candidates for biologics was considered and 15 potentially relevant infections were identified., Conclusions: Fifteen disease-specific recommendations were formulated on the basis of high level of agreement among the experts panel.

Autoimmunity and chronic inflammation recognize numerous shared factors and, as a result, the resulting diseases frequently coexist in the same patients or respond to the same treatments. Among the convenient truths of autoimmune and chronic inflammatory diseases, there is now agreement that these are complex conditions in which the individual genetic predisposition provides a rate of heritability. The concordance rates in monozygotic and dizygotic twins allows to estimate the weight of the environment in determining disease susceptibility, despite recent data supporting that only a minority of immune markers depend on hereditary factors. Concordance rates in monozygotic and dizygotic twins should be evaluated over an observation period to minimize the risk of false negatives and this is well represented by type I diabetes mellitus. Further, concordance rates in monozygotic twins should be compared to those in dizygotic twins, which share 50% of their genes, as in regular siblings, but also young-age environmental factors. Twin studies have been extensively performed in several autoimmune conditions and cumulatively suggest that some diseases, i.e. celiac disease and psoriasis, are highly genetically determined, while rheumatoid arthritis or systemic sclerosis have a limited role for genetics. These observations are necessary to interpret data gathered by genome-wide association studies of polymorphisms and DNA methylation in MZ twins. New high-throughput technological platforms are awaited to provide new insights into the mechanisms of disease discordance in twins beyond strong associations such as those with HLA alleles., (Copyright © 2017 Elsevier Ltd.

This study aims to characterize myositis-specific antibodies in a well-defined cohort of patients with idiopathic inflammatory myopathy and to determine their association with cancer. Sera from 40 patients with polymyositis, dermatomyositis, and controls were tested by protein and RNA immunoprecipitation to detect autoantibodies, and immunoprecipitation-Western blot was used for anti-MJ/NXP-2, anti-MDA5, and anti-TIF1γ/α identification. Medical records were re-evaluated with specific focus on cancer. Anti-MJ/NXP-2 and anti-TIF1γ/α were the most common antibodies in dermatomyositis. In six dermatomyositis cases, we found five solid forms of cancer and one Hodgkin's lymphoma in long-term remission. Among patients with cancer-associated dermatomyositis, three were positive for anti-TIF1γ/α, two for anti-Mi-2, and one for anti-MJ/NXP-2. The strongest positivity of anti-TIF1γ was seen in two active forms of cancer, and this antibody was either negative or positive at low titers in the absence of cancer or in the 7-year remission Hodgkin's lymphoma. Four out of twenty (20 %) patients with polymyositis had solid cancer, but no specific association with autoantibodies was identified; further, none of the four cases of antisynthetase syndrome had a history of cancer. No serum myositis-associated autoantibody was observed in control sera, resulting in positive predictive value 75 %, negative predictive value 78.5 %, sensitivity 50 %, specificity 92 %, and area under the ROC curve 0.7083 for the risk of paraneoplastic DM in anti-TIF1γ/α (+) patients. Myositis-specific autoantibodies can be identified thanks to the use of immunoprecipitation, and their association with cancer is particularly clear for anti-TIF1γ/α in dermatomyositis. This association should be evaluated in a prospective study by immunoprecipitation in clinical practice.

The heart involvement in systemic autoimmune diseases represents a growing burden for patients and health systems. Cardiac function can be impaired as a consequence of systemic conditions and manifests with threatening clinical pictures or chronic myocardial damage. Direct injuries are mediated by the presence of inflammatory infiltrate which, even though unusual, is one of the most danger manifestations requiring prompt recognition and treatment. On the other hand, a not well-managed inflammatory status leads to accelerated atherosclerosis that precipitates ischemic disease. All cardiac structures may be damaged with different grades of intensity; moreover, lesions can appear simultaneously or more frequently at a short distance from each other leading to the onset of varied clinical pictures. The pathogenesis of heart damages in systemic autoimmune conditions is not yet completely understood for the great part of situations, even if several mechanisms have been investigated. The principal biochemical circuits refer to the damaging role of autoantibodies on cardiac tissues and the precipitation of immune complexes on endocardium. These events are finally responsible of inflammatory infiltration which leads to subsequent worsening of the previous damage. For these reasons, it appears of paramount importance a regular and deepened cardiovascular assessment to prevent a progressive evolution toward heart failure in patient affected by autoimmune diseases.

Aim: The primary aim of this study was to explore the safety profile of biologic treatments in Behçet's disease (BD), based on their mechanism of action; the secondary aim was to study any potential variation in terms of retention rate according to each single drug., Method: We studied a total of 85 treatment regimens with biologic agents from 64 patients. The total follow-up was calculated as 8640 patient-years (anti-tumor necrosis factor [TNF]-alpha 7.020, anti-interleukin [IL]-beta 1.368). Cumulative rates of drug retention were studied using the Kaplan-Meier plot and covariates in the regression model included the mechanism of action of the biologic agent, other concomitant therapies, disease duration, sex, age at start of drug therapy; for each confounding factor hazard ratios (HR) were calculated., Results: The most frequently prescribed biologic treatments were anti-TNF-alpha agents (79%), while anti-IL1-beta was used in the remaining regimens. Concomitant disease-modifying antirheumatic drugs were prescribed in 36% of patients, mainly cyclosporine and methotrexate, while in 35/85 regimens low-dose glucocorticoids were associated. During the follow-up, in all but one regimen the safety profile was free of any adverse events or serious adverse events; we observed only one case of endocarditis, reported during the 10th month of etanercept., Conclusion: Data from a large multicenter cohort suggest that anti-TNF-alpha and anti-IL1-beta agents are characterized by an excellent safety profile in BD., (© 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.)

Purpose: Nailfold videocapillaroscopy (NVC) identifies the microvascular hallmarks of systemic sclerosis (SSc) and vascular endothelial growth factor (VEGF) and may play a pivotal role in the associated vasculopathy. The aim of the present study was to compare NVC alterations with clinical subsets, internal organ involvement, and serum VEGF levels in a cohort of selected SSc cases., Methods: We studied 44 patients with SSc who were evaluated within 3 months from enrollment by NVC, skin score, severity index, pulmonary function tests, carbon monoxide diffusing capacity (DLCO), echocardiography, pulmonary high-resolution computed tomography (HRCT), gastroesophageal (GE) endoscopy or manometry or X-ray, and serum autoantibodies. Serum VEGF-A levels were determined by ELISA in 72 SSc patients and 31 healthy controls., Results: Giant capillaries were inversely correlated with age (p = 0.034, r = -0.34) and to the extent of reticular pattern at HRCT (p = 0.04, r = -0.5). Avascular areas were directly correlated with capillaroscopy skin ulcer risk index (CSURI) (p = 0.006, r = +0.4) and severity index (p = 0.004, r = +0.5). The mean capillary density was directly correlated to the ulcer number (p = 0.02, r = +0.4) and to DLCO/alveolar volume (p = 0.02, r = +0.4) and inversely correlated with severity index (p = 0.01, r = -0.4) and skin score (p = 0.02, r = -0.4). Serum VEGF levels were higher in the SSc population vs controls (p = 0.03) and inversely correlated with DLCO (p = 0.01, r =-0.4) and directly with ground-glass and reticular pattern at HRCT (p = 0.04, r = +0.4 for both)., Conclusions: Our data suggest the importance of NVC not only for the diagnosis, but also for the global evaluation of SSc patients. Of note, serum VEGF levels may act as a biomarker of interstitial lung involvement., Competing Interests: MDS and AC received travel support from Actelion. The other authors declare that they have no conflict of interest. Ethical approval All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards. Informed consent All subjects enrolled signed a written informed consent for serum samples and data analysis after approval from the local ethical committee.

Psoriatic arthritis (PsA) is characterized by chronic inflammation of peripheral joints and axial skeleton, associated with a strong genetic background. Clinics include enthesitis or dactylitis and extra-articular involvement as uveitis or inflammatory bowel disease, while treatment options range from nonsteroidal anti-inflammatory drugs (NSAIDs) to biologics, targeting TNF α or Th17. No serum autoantibody is associated with PsA, while other biomarkers have been proposed for early diagnosis or to predict treatment response. To better discuss this area of growing interest we performed a systematic review of the literature on biomarkers in PsA. Our research retrieved 408 papers, and 38 were included in the analysis. Based on the available literature, we draw some recommendations for the use of biomarkers in the management of patients with PsA.

At the 2015 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) in Stockholm, Sweden, rheumatology and dermatology trainees engaged in psoriasis or psoriatic arthritis research presented their work to meeting attendees in a trainees symposium. This report briefly reviews 6 oral presentations and 20 posters presented at the meeting.

Tattoos are defined as the introduction of exogenous pigments into the dermis in order to produce a permanent design. This process may occur unintentional or may be deliberately administered for cosmetic or medical reasons. Tattoos have been around for over 5000 years and over time have evolved to represent a common cosmetic practice worldwide. Currently, adverse reactions are relatively rare and generally unpredictable and predominantly include immune-mediated reactions and skin infections. Along with better healthcare standards and more stringent public health mandates such as the provision of disposable needles, major infectious complications related to hepatitis and human retroviral infections have decreased significantly. When they do occur, skin infections are most frequently associated with Staphylococcus aureus or Streptococcus pyogenes. The aim of this study is to review the types and rates of medical complications of permanent tattoos. PubMed search and search dates were open ended. Acute local inflammation is the most common complication, but infections, allergic contact dermatitis, and other inflammatory or immune responses that are not well-characterized may occur. As many patients with immune reactions to tattoos do not react on skin or patch testing, it is postulated that the antigens contained in dyes or pigments are such small molecules that they need to be haptenized in order to become immunogenic. Red ink is associated more frequently with long-term reactions, including granulomatous and pseudolymphomatous phenomena or morphea-like lesions and vasculitis. Exacerbation of preexisting psoriasis, atopic dermatitis, and pyoderma gangrenosum may occur after tattooing. There is no well-defined association between cancer and tattoos. The treatment of tattoo-related complications may include local destructive measures (cryotherapy, electro-surgery, dermabrasion, chemical destruction, ablative laser destruction), surgical excision, and thermolysis of the pigment using Q-switched laser therapy.

Psoriatic arthritis (PsA) is a chronic inflammatory condition associated with skin psoriasis and manifests a wide clinical phenotype, with proposed differences between sexes. Current treatments are based on traditional disease-modifying anti-rheumatic drugs (DMARD), and biologic agents and studies have reported different clinical response patterns depending on sex factors. We aimed to identify sex differences in drug retention rate in patients with PsA and performed a systematic research on MEDLINE, EMBASE and Cochrane databases (1979 to June 2015) for studies regarding effectiveness (measured as drug retention rate) in PsA in both traditional DMARDs and biologics. Demographic data as well as retention rates between sexes were extracted. From a total 709 retrieved references, we included 9 articles for the final analysis. Only one study reported data regarding DMARDs, while eight studies reported retention rate for anti-tumor necrosis factor (TNF) biologics, mainly infliximab, adalimumab and etanercept. No differences were reported in retention rates between sexes for methotrexate, while women manifested lower retention rates compared to men with regard to anti-TNF. We highlight the need to include sex differences in the management flow chart of patients with PsA.

The prevalence of ANA and anti-ENA in the general population is not well established, especially their clinical significance in healthy subjects. We herein determined the prevalence and predictive value of serum ANA and anti-ENA for connective tissue diseases (CTD), cancer, and mortality. We took advantage of a randomly selected sample of the 1998 general population (Isola I) consisting of 2828 subjects (53% women, age 43±13 years) from a well-defined Northern Italian area. Serum ANA and anti-ENA were tested on the 2690 samples available in 2012 (Isola II, 50% women, age 58±13 years). Administrative databases were searched for CTD, cancer diagnosis, and death cases occurring between enrollment and December 31, 2013. The hazard ratio (HR) was calculated for incident cases. Serum ANA is positive in 18.1% for any titer and 6.1% for titers ≥1:160, 23% in subjects over 50 years and 13.1% and 6.1% for any titer and titers ≥1:160, respectively, in women. The HR for CTD development was significantly high for all ANA titers, with the highest for ANA ≥1:160 (HR 14.19, 95% CI 3.07-65.68). ANA positivity was not associated with cancer (HR 1.03; 95% CI 0.75-1.43), or with mortality (HR adjusted for age and sex 1.40; 95% CI 0.94-2.09). Serum anti-ENA is positive in a minority of subjects with highest figures for anti-nucleosome (1.9%), -histone (1.6%) and -PM/Scl (1.5%). In conclusion, serum ANA prevalence in the general population is highest in senior subjects and in women, while the female predominance is significantly lower compared to overt CTD. Serum ANA is associated with an increased probability of CTD development over time, but does not influence survival or cancer risk., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Eye involvement represents a common finding in patients with systemic autoimmune diseases, particularly rheumatoid arthritis, Sjogren syndrome, seronegative spondyloarthropathy, and antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. The eye is a privileged immune site but commensal bacteria are found on the ocular surface. The eye injury may be inflammatory, vascular or infectious, as well as iatrogenic, as in the case of hydroxychloroquine, chloroquine, corticosteroids, and bisphosphonates. Manifestations may affect different components of the eye, with episcleritis involving the episclera, a thin layer of tissue covering the sclera; scleritis being an inflammation of the sclera potentially leading to blindness; keratitis, referring to corneal inflammation frequently associated with scleritis; and uveitis as the inflammation of the uvea, including the iris, ciliary body, and choroid, subdivided into anterior, posterior, or panuveitis. As blindness may result from the eye involvement, clinicians should be aware of the possible manifestations and their management also independent of the ophthalmologist opinion as the therapeutic approach generally points to the underlying diseases. In some cases, the eye involvement may have a diagnostic implication, as for episcleritis in rheumatoid arthritis, or acute anterior uveitis in seronegative spondyloarthritis. Nonetheless, some conditions lack specificity, as in the case of dry eye which affects nearly 30 % of the general population. The aim of this review is to elucidate to non-ophthalmologists the major ocular complications of rheumatic diseases and their specific management and treatment options.

Spondyloarthritidies represent a group of conditions affecting the axial and peripheral muscoloskeletal apparatus and are often associated with psoriasis, infections, and inflammatory bowel diseases. Other diseases included in this category are psoriatic arthritis, ankylosing spondylitis, and enteropathic arthritis. Reactive arthritis is an elusive spondyloarthritis, commonly occurring 1 to 3 weeks after a digestive or a genitourinary tract infection, in which microorganisms do not infect the joint directly. Reactive arthritis is classically characterized by large-joint arthritis, urethritis in men and cervicitis in women, and eye inflammation (usually conjunctivitis or uveitis) but encompasses numerous other symptoms and signs, including manifestations of dermatologic interest such as keratoderma blenorrhagicum and circinate balanitis. The diagnosis of reactive arthritis is clinical, and the infectious agent cannot always be identified due to disease latency after the infection. Most cases are self-limiting, but reactive arthritis may become chronic in 30% of cases. Treatment options include anti-inflammatory drugs, steroids, and sulfasalazine; biologic agents, such as tumor necrosis factor α (TNF-α) blockers, have been recently used, but there are only a few randomized clinical trials on the treatment of reactive arthritis. The effectiveness of antimicrobials needs further evaluation., (Copyright © 2015 Elsevier Inc. All rights reserved.)

As our understanding of the pathogenesis of autoimmune diseases is growing, new therapies are being developed to target disease-specific pathways. Since the introduction of etanercept in 1998, several biotechnological agents have been developed, most of them indicated in the treatment of rheumatoid arthritis, but also psoriatic arthritis. Most currently available molecules target TNF-alfa with different strategies (i.e., etanercept, infliximab, adalimumab, golimumab, and certolizumab pegol), IL-6 (tocilizumab), CTLA-4 (abatacept), and B cells (rituximab, belimumab) as they are key mediators in the cascade of inflammation. Further, small molecules have been recently developed to target intracellular signaling, such as Janus Kinases for tofacitinib, the first FDA-approved small molecule for rheumatoid arthritis. Most novel treatments are being developed for arthritis with specific differences between rheumatoid and psoriatic arthritis, as well as for systemic lupus erythematosus, following the approval of belimumab. Finally, biologic therapies are effective also in gout, mainly targeting interleukin-1 to block the inflammasome. This review article describes the new and upcoming treatment options for rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, and gout to dissect what we should be aware of when discussing these new and promising molecules.
