OBJECTIVES: The aim of our study was to investigate cause-specific mortality in rheumatoid arthritis (RA) subjects living in Italy. METHODS: We identified in the electronic archive of the Veneto Region patients aged 20-89 years who were exempt from co-payment for RA in January 2010, and linked them with the archive of causes of deaths of the period 2010-2015. Causes of death were coded according to the International Classification of Diseases, 10th Edition. Standardised mortality ratios (SMRs) with 95% confidence intervals were computed as the ratios between deaths observed in the cohort, and those expected according to age- and gender-specific regional mortality rates...

Chikungunya virus (CHIKV) is an arthropod-borne alphavirus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes. It is responsible for a febrile illness, typically accompanied by maculopapular rash and severe, incapacitating arthralgia. The disease, although generally self-limiting, frequently evolves into a long-lasting, debilitating rheumatic disorder, which shares many clinical features with rheumatoid arthritis (RA). The underlying mechanism by which CHIKV induces persistent arthritis remains under investigation, however, currently, attention is drawn to the fact, that chronic chikungunya (CHIK) and RA have many common cellular and cytokine pathways involved in their pathogenesis...

OBJECTIVES: To explore the association of TLR7 gene copy number variations (CNVs) with the susceptibility of ankylosing spondylitis (AS). METHODS: The case control study was performed in 649 Chinese Han patients with AS and 628 healthy controls. The copy numbers of TLR7 gene (2 fragments) were measured by AccuCopyTM methods. Chi-square and logistic regression models were performed to investigate the association of TLR7 gene CNVs with AS. Odds ratio (ORs) and 95% confidence intervals (CIs) was calculated to estimate AS risk and the Bonferroni correction was applied owing to multiple testing...

OBJECTIVES: Early arthritis clinics (EAC) aim to improve rheumatoid arthritis (RA) outcomes by tailoring treatment targeting to remission. Our aim was to analyse disease course and relevant predictors over 2 years in early arthritis; we also assessed the applicability of the "treat-to-target approach" in a real-life EAC. METHODS: Patients with early arthritis recruited at the EAC of the University Hospital of Heraklion were followed prospectively according to a follow-up protocol for two years, without implementing a pre-specified treatment protocol, to capture real-life practices...

OBJECTIVES: B cells play an important role in the initiation and progression of systemic lupus erythematosus (SLE). Accordingly, B cell-targeted therapy has been suggested as a new rational approach for treating lupus. Belimumab, a human monoclonal antibody directed against B lymphocyte stimulator (BLyS), was reported as the first biological treatment effective in reducing mild-to-moderate SLE disease activity by using different scoring systems and endpoints. Conversely clinical trials with rituximab, a chimeric monoclonal antibody directed against the CD20 expressed by B cells, have failed to achieve primary endpoints in spite of a number of reports showing its beneficial effects...

OBJECTIVES: To compare the long-term morbidity of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome treated by tonsillectomy (TE) in childhood to that of matched controls. METHODS: We identified 132 PFAPA patients from the medical records treated by TE in 1987-2007 in Oulu University Hospital, Finland. Altogether 119 patients participated the follow-up study and 94 were clinically examined on average 9.0 years after TE...

OBJECTIVES: In 2011 an ACR/EULAR collaboration developed new remission definitions for RA. In the present study, we evaluated the prevalence and predictive validity of these new ACR/EULAR remission criteria in 4 different European early rheumatoid arthritis cohorts. METHODS: Data from a tot al of 722 patients with early RA were analysed. Presence of remission at 6 months, as defined by one of the 4 proposed ACR/EULAR remission definitions was used to predict good functional and radiological outcome between 1 and 2 years of follow-up...

OBJECTIVES: Guidelines for preventing Pneumocystis pneumonia (PCP) in HIV patients are based on CD4 below 200/mm3. Such cut-off value is suggested to guide prophylaxis in non-HIV conditions (NHIV) especially in autoimmune and inflammatory diseases (AD). We aimed to determine if CD4 could be used to guide PCP prophylaxis in AD. METHODS: CD4 and lymphocyte-count were retrospectively studied in patients diagnosed with PCP between January 2013 and February 2016. RESULTS: 129 patients were included...

OBJECTIVES: The proprotein convertase enzyme FURIN is a critical regulator of the anti-inflammatory TGFβ-1 cytokine and peripheral immune tolerance. In T cells, FURIN is co-regulated with IFN-γ and thus highly expressed in T helper 1 type cells. Previous studies have demonstrated that FURIN is upregulated in inflammatory conditions, including atherosclerosis, rheumatoid arthritis and systemic lupus erythematosus. Here, we evaluated the levels of FURIN in the plasma and peripheral blood mononuclear cells (PBMCs) of patients with primary Sjögren's syndrome (pSS) and in healthy controls...

Polyarteritis nodosa (PAN) is a rare form of primary systemic vasculitis with heterogeneous presentations, treatments and disease course. Historical approaches to classification and diagnostic terminology are reviewed. Since differentiation of PAN from microscopic polyangiitis (MPA) and other ANCA vasculitides by the Chapel Hill conference statements, and with hepatitis associated PAN defined as a secondary vasculitis, the phenotyping and subclassification of PAN has received little attention. Monogenic disorders similar to PAN have been described (familial Mediterranean fever, Adenosine Deaminase-2 deficiency), and cutaneous PAN and single organ vasculitis, discussed...

OBJECTIVES: Systemic sclerosis (SSc) is a chronic, autoimmune connective tissue disease with a female predominance. The reason for the female predilection in SSc may relate to the difference in hormones between the genders. There are no current data on the influence male-to-female sex transition may have in the development of SSc. We report three patients who developed SSc after initiating the transgender process, and review current literature in regards to transgender patients with connective tissue disease (CTD)...

OBJECTIVES: To identify biomarkers for disease activity in IgG4-related disease (IgG4-RD) and primary Sjögren's syndrome (pSS). METHODS: Forty-three consecutive treatment-naïve patients with IgG4-RD, 62 patients with pSS, and 5 patients with sicca syndrome were enrolled. IgG4-RD and pSS disease activity was assessed based on the IgG4-RD responder index (IgG4-RD RI) and EULAR Sjögren's Syndrome Disease Activity Index (ES- SDAI), respectively. The associations of biomarkers with disease activity were examined...

OBJECTIVES: Psychological stress is thought to play a major role in the development and exacerbation of autoimmune diseases in general, as well as in rheumatoid arthritis (RA) in particular. The aims of the current study are to compare retrospective self-reports of childhood maltreatment and lifetime major life/traumatic experiences of American and Israeli RA patients, using standardised instruments, while adjusting for concomitant mental disorders and psychological distress, in order to rule out their part in the subjective reports, thus addressing the trans-cultural robustness of the association between childhood maltreatment, traumatic experiences and RA...

OBJECTIVES: Retroperitoneal fibrosis (RPF) is a rare disease, with unknown aetiology (idiopathic RPF: iRPF) in two-thirds of cases. A subset of iRPF may be a manifestation of IgG4-related disease (IgG4-RD). Thus, recognition of IgG4-RD-RPF is crucial to optimise patient's care with iRPF. The current study aimed to examine imaging specific patterns, which could help differentiate between IgG4-RD-RPF and iRPF, and thus skip performing biopsies. METHODS: This analysis included patients with iRPF and a retroperitoneal biopsy at the Lille University Hospital, France...
