Abstract
Raynaud's phenomenon (RP) is a clinical disorder characterized by recurrent, reversible episodes of digital vasospasm. RP can be classified as primary (pRP) or secondary, depending on whether it occurs as a benign condition (not disease-associated) or is associated with other diseases, mainly of the connective tissues. In both cases, it can be triggered by environmental factors, as indicated by the increased incidence of pRP episodes following exposure to cold, vibration injury or chemicals. The purpose of this prospective case-control study was to assess, in an Italian cohort of 132 pRP patients, the association of the phenomenon with demographic, lifestyle habits, environmental and work-related factors. Compared to healthy controls, pRP was found to be inversely associated with the use of contact lenses (OR = 0.4; p = 0.004) and of chlorous-based disinfectants (OR = 0.3; p < 0.001) and directly associated with the presence of prosthesis implants (OR = 5.3; p = 0.001) and the use of hydrogen peroxide-based compounds (OR = 2.6; p = 0.002), suggesting that the latter should be avoided in RP affected patients. Multivariate and multivariable analysis confirmed the associations. Further investigations are needed to understand the mechanism(s) underlying these findings.

Abstract
Salivary gland (SG) biopsy is a technique broadly applied for the diagnosis of primary Sjögren's syndrome (pSS), lymphoma accompanying SS, sarcoidosis, amyloidosis, and IgG4-related disease The most peculiar feature of pSS on biopsy is focal lymphocytic sialadenitis. In the past, several histological scores have been reported in the literature to describe glandular involvement during pSS. However, the variability among centres in reporting glandular scores is one of the rationales behind the development of standardised consensus guidance. SGs as well as lacrimal glands are involved in up to 50% of patients with IgG4-related disease with 3 histopathological hallmarks such as dense lymphoplasmacytic infiltration, storiform fibrosis and obliterative phlebitis. SGs can be also affected by amyloidosis with MSG biopsy being more sensitive than that of rectal mucosa or subcutaneous fat. SG involvement is a rare manifestation during sarcoidosis, and the presence of non-caseating granulomas needs to be differentiated from granulomas of other etiology. This review article provides an overview of normal and pathological SGs in the context of rheumatic diseases, identifying key elements in the tissue as diagnostic and prognostic biomarkers, useful in the current clinical practice.

Abstract
Macrophage activation syndrome (MAS) is hyperinflammatory life-threatening syndrome, associated typically with high levels of serum ferritin. This is an iron storage protein including heavy (H) and light (L) subunits, categorized on their molecular weight. The H-/L subunits ratio may be different in tissues, depending on the specific tissue and pathophysiological status. In this study, we analysed the bone marrow (BM) biopsies of adult MAS patients to assess the presence of: (i) H-ferritin and L-ferritin; (ii) CD68+ /H-ferritin+ and CD68+ /L-ferritin+ ; and (iii) interleukin (IL)-1β, tumour necrosis factor (TNF) and interferon (IFN)-γ. We also explored possible correlations of these results with clinical data. H-ferritin, IL-1β, TNF and IFN-γ were increased significantly in MAS. Furthermore, an increased number of CD68+ /H-ferritin+ cells and an infiltrate of cells co-expressing H-ferritin and IL-12, suggesting an infiltrate of M1 macrophages, were observed. H-ferritin levels and CD68+ /H-ferritin+ cells were correlated with haematological involvement of the disease, serum ferritin and C-reactive protein. L-ferritin and CD68+ /L-ferritin+ cells did not correlate with these parameters. In conclusion, during MAS, H-ferritin, CD68+ /H-ferritin+ cells and proinflammatory cytokines were increased significantly in the BM inflammatory infiltrate, pointing out a possible vicious pathogenic loop. To date, H-ferritin and CD68+ /H-ferritin+ were associated significantly with haematological involvement of the disease, suggesting biomarkers assessing severity of clinical picture.

Abstract
T helper 9 (Th9) cells and interleukin (IL)-9 are involved in the pathogenesis of several autoimmune diseases. The exact role of IL-9 and Th9 cells in patients with systemic sclerosis (SSc) have not yet been studied adequately. IL-9, IL-9R, transcription factor PU.1 (PU.1), IL-4, thymic stromal lymphopoietin (TSLP) and transforming growth factor (TGF)-β expression were assessed in skin and kidney biopsies of SSc patients and healthy controls (HC) by immunohistochemistry (IHC). The cellular source of IL-9 was also analysed by confocal microscopy analysis. Peripheral IL-9-producing cells were also studied by flow cytometry. The functional relevance of IL-9 increased expression in SSc was also investigated. Our results demonstrated a strong expression of IL-9, IL-9R, IL-4, TSLP and TGF-β in skin tissues of patients with both limited and diffuse SSc. IL-9 expression was observed mainly in the context of skin infiltrating mononuclear cells and keratinizing squamous epithelium. IL-9 over-expression was also observed in renal biopsies of patients with SSc. IL-9 producing cells in the skin were identified as Th9 cells. Similarly, Th9 cells were expanded and were the major source of IL-9 among SSc peripheral blood mononuclear cells (PBMC), their percentage being correlated directly with the modified Rodnan skin score. Infiltrating mononuclear cells, mast cells and neutrophils expressed IL-9R. In in-vitro studies stimulation with rIL-9 significantly induced NET (neutrophil extracellular traps) release by dying cells (NETosis) in neutrophils, expansion of mast cells and increase of anti-systemic scleroderma 70 (Scl70) production by B cells. Our findings suggest that Th9 cells and IL-9 could be implicated in the pathogenesis of SSc.

Abstract
Interleukin (IL)-9 is a 28-30 kDa monomeric glycosylated polypeptide belonging to the IL-7/IL-9 family of proteins that bind to a composite receptor consisting of the private receptor IL-9R and the IL-2 receptor, gamma (IL-2RG), a common gamma subunit shared by the receptors of many different cytokines. The IL-9R is expressed widely and IL-9 impacts a number of effector cells, such as effector T cells, B cells, innate lymphoid cells, mast cells, polymorphonuclear cells, epithelial cells and smooth muscle cells, playing an important role in regulating inflammatory immunity. The critical role of IL-9 in promoting cellular and humoral immune responses makes it an important focus of potential therapeutic interventions. Recently, a defined subset of T helper type cells, Th9 cells, has been identified by the potent production of IL-9. The involvement of the Th9 cell subset has been described in many types of inflammatory diseases, namely atopic diseases, helminth infections, experimental autoimmune encephalomyelitis and ulcerative colitis. In this review, we summarize the IL-9 biological activities, highlighting roles for IL-9 and Th9 cells in rheumatoid and psoriatic arthritis, systemic vasculitis, systemic lupus erythematosus and systemic sclerosis.

Abstract
Cytokines such as tumour necrosis factor (TNF)-α, interleukin (IL)-12, interferon (IFN)-γ, IL-23 and, more recently, IL-9, have been implicated in the initiation/maintenance of inflammation in psoriasis and psoriatic arthritis (PsA). In the present study we aimed to characterize the role of γδ T cells in peripheral blood and synovial fluid of PsA patients and to investigate their response to in-vitro stimulation with antigen or cytokines (IL-9 and IL-23). γδ T cells isolated from peripheral blood mononuclear cells and synovial fluid were analysed by flow cytometry to evaluate the phenotype and cytokine production. IL-23R and IL-9R gene expression were also evaluated by reverse transcription-polymerase chain reaction (RT-PCR). Peripheral blood mononuclear cells (PBMC), sorted γδ T cells and γδ cell lines were also stimulated in vitro with isopentenyl pyrophosphate (IPP), recombinant IL-9 or recombinant IL-23. Our results show an expansion of γδ T cells with a predominant effector memory phenotype in peripheral blood and synovium of untreated PsA patients, which reverses significantly after treatment with anti-TNF-α or anti-IL-12/IL-23R monoclonal antibodies (mAbs). Moreover, in PsA patients γδ T cells activation is driven prevalently by IL-9/IL-9R interaction, and not only by IL-23/IL-23R. Together these findings indicate γδ T cells and IL-9 as new players in the pathogenesis of PsA.

Abstract
Adult-onset Still's disease (AOSD) patients may show an evanescent salmon-pink erythema appearing during febrile attacks and reducing without fever. Some patients may experience this eruption for many weeks. During AOSD, exceptionally high serum levels of ferritin may be observed; it is an iron storage protein composed of 24 subunits, heavy (H) subunits and light (L) subunits. The ferritin enriched in L subunits (L-ferritin) and the ferritin enriched in H subunits (H-ferritin) may be observed in different tissues. In this work, we aimed to investigate the skin expression of both H-and L-ferritin and the number of macrophages expressing these molecules from AOSD patients with persistent cutaneous lesions. We observed an increased expression of H-ferritin in the skin, associated with an infiltrate in the biopsies obtained from persistent cutaneous lesions of AOSD patients. Furthermore, a positive correlation between H-ferritin skin levels as well as the number of CD68(+) /H-ferritin(+) cells and the multi-visceral involvement of the disease was observed. Our data showed an increased expression of H-ferritin in the skin of AOSD patients, associated with a strong infiltrate of CD68(+) /H-ferritin(+) cells. Furthermore, a correlation between the levels of H-ferritin as well as of the number of CD68(+) /H-ferritin(+) cells and the multi-visceral involvement of the disease was observed.

Abstract
The objective of this multicentric case-control study was to investigate if a history of autoimmune disease (AD) in first-degree relatives (FDR) is a risk factor for systemic lupus erythematosus (SLE) and to evaluate the risk of AD among FDR of SLE patients. Cases were Italian SLE patients consecutively enrolled. Controls were orthopaedic inpatients without any autoimmune diseases.The strength of the association between family history of AD and SLE was measured as an odds ratio (OR) calculated from the coefficient of an unconditional regression model. To calculate the risk of AD among FDR of SLE patients, the extended generalized estimating equation technique was used. In total, 154 SLE cases and 140 controls were enrolled. A family history of AD was reported by 22.7% of SLE patients and by 5.7% of the controls. The risk of SLE increased with the number of FDR with AD (one FDR affected, OR 4.1; two or more, OR 11.3). The probability of having AD was higher among FDR of SLE cases in comparison to FDR of controls (RR 4.6; 95%CI 1.9-11.1). A female SLE patient conferred an increased risk of AD to her FDR; this risk is doubled in females (OR 10.3; 95% CI 3.1-34.4).

Abstract
In a previous study, we showed an imbalance in the cytotoxic phenotype of circulating PBMC of IBD patients, possibly related to an alteration in the cytotoxic activity, which might play a role in the immunopathogenesis of IBD. γ/δ T cells, which are increased in the PBMC of IBD patients, represent a minor population of peripheral lymphocytes displaying cytolytic potential and showing both MHC and non-MHC cytotoxicity. This study was performed in order to verify their role in the cytotoxic activity of PBMC from IBD patients and correlate this activity to UC and CD, respectively. We observed a decreased NK cytotoxicity of PBMC in both UC and CD patients and this findings was unrelated to γ/δ T lymphocytes. In fact, both total and γ/δ-depleted PBMC of IBD patients, showed comparable lytic activity. On the contrary, the ADCC lytic activity was within normal range in our patients, ad was not modified by removal of γ/δ cells. The increase of Vδ1+ T cells, previously observed in our patients, seems to be unrelated to this functional impairment, because of a low cytotoxic activity displayed by this subset. Alternatively, the expanded Vδ1+ T cells could be involved in the pathogenesis of the autoimmune phenomena observed in IBD, by a mechanism different from cytotoxicity, such as autoantibodies production and/or loss of tolerance.

Abstract
Compelling evidence suggests that interleukin (IL)-17 and IL-17-producing cells play a pivotal role in the pathogenesis of primary Sjögren's syndrome (pSS). We investigated phenotypical and functional effects of the anti-CD20 antibody rituximab (RTX) on circulating and glandular IL-17-producing T cells in pSS. RTX is able to deplete glandular IL-17(+) CD3(+) CD4(-) CD8(-) double-negative (DN) and CD4(+) Th17 cells as well as circulating IL-17(+) DN T cells. A fraction of glandular and circulating IL-17(+) DN cells and CD4(+) T helper type 17 (Th17) cells co-expresses CD20 on the cell surface explaining, at least in part, such depletive capacity of RTX. The exposure to RTX does not rescue the in-vitro corticosteroid resistance of IL-17(+) DN T cells. Our results support further the therapeutic role in pSS of RTX that, despite its B cell specificity, appears able to also hamper IL-17-producing T cells in this disease.

Abstract
In this work, we aimed to evaluate the levels of ferritin enriched in H subunits (H-ferritin) and ferritin enriched in L subunits (L-ferritin) and the cells expressing these two molecules in the lymph node (LN) biopsies obtained from adult-onset Still's disease (AOSD) patients, and the possible correlation among these data and the severity of the disease. Ten patients with AOSD underwent LN biopsy. All the samples were stained by immunofluorescence. A statistical analysis was performed to estimate the possible correlation among both H-ferritin and L-ferritin tissue expression and the clinical picture of the disease. Furthermore, the same analysis was performed to evaluate the possible correlation among the number of CD68(+)/H-ferritin(+) or CD68(+)/L-ferritin(+) cells and the clinical picture. Immunofluorescence analysis demonstrated an increased tissue H-ferritin expression in the LNs of AOSD patients. This increased expression correlated with the severity of the disease. An increased number of CD68 macrophages expressing H-ferritin was observed in the LN samples of our patients. Furthermore, we observed that the number of CD68(+)/H-ferritin(+) cells correlated significantly with the severity of the clinical picture. Our data showed an imbalance between the levels of H- and L-ferritin in LNs of AOSD patients and the evidence of an increased number of CD68(+)/H-ferritin(+) cells in the same organs. Furthermore, a correlation among both the tissue H-ferritin levels and the CD68(+)/H-ferritin(+) cells and the clinical picture was observed.

Abstract
The aim of this study was to investigate the expression of the interleukin (IL)-36 axis in patients with primary Sjögren's syndrome (pSS). Blood and minor labial salivary glands (MSG) biopsies were obtained from 35 pSS and 20 non-Sjögren's syndrome patients (nSS) patients. Serum IL-36α was assayed by enzyme-linked immunosorbent assay (ELISA). IL-36α, IL-36R, IL-36RA, IL-38, IL-22, IL-17, IL-23p19 and expression in MSGs was assessed by reverse transcription-polymerase chain reaction (RT-PCR), and tissue IL-36α and IL-38 expression was also investigated by immunohistochemistry (IHC). αβ and γδ T cells and CD68(+) cells isolated from MSGs were also studied by flow cytometry and confocal microscopy analysis. IL-36α was over-expressed significantly in the serum and in the salivary glands of pSS. Salivary gland IL-36α expression was correlated with the expression levels of IL-17, IL-22 and IL-23p19. IL-38, that acts as inhibitor of IL-36α, was also up-regulated in pSS. αβ(+) CD3(+) T cells and CD68(+) cells were the major source of IL-36α in minor salivary glands of pSS. γδ T cells were not significantly expanded in the salivary glands of pSS but produced more IL-17, as their percentage correlated with the focus score. Higher expression of IL-36α and IL-36R was also demonstrated in γδ T cells isolated from pSS compared to controls. In this study we demonstrate that a significant increase in circulating and tissue levels of IL-36α occurs in pSS patients.

Abstract
OBJECTIVE Systemic autoimmune diseases, in particular systemic lupus erythematosus and rheumatoid arthritis, are characterized by a high risk of premature cardiovascular (CV) events. Disease-related characteristics and traditional CV disease risk factors may contribute to atherosclerotic damage. However, there are limited data on the risk of overt CV events in primary Sjögren's syndrome (pSS). METHODS We retrospectively analysed a cohort of patients with 1343 pSS. Disease-related clinical and laboratory data, traditional CV disease risk factors and overt CV events were recorded. Prevalence of traditional CV disease risk factors and of major CV events was compared between a subgroup of 788 female patients with pSS aged from 35 to 74 years and 4774 age-matched healthy women. RESULTS Hypertension and hypercholesterolaemia were more prevalent, whereas smoking, obesity and diabetes mellitus were less prevalent, in women with pSS than in control subjects. Cerebrovascular events (2.5% vs. 1.4%, P = 0.005) and myocardial infarction (MI) (1.0% vs. 0.4%, P = 0.002) were more common in patients with pSS. In the whole population, central nervous system involvement (odds ratio (OR) 5.6, 95% confidence interval (CI) 1.35-23.7, P = 0.02) and use of immunosuppressive therapy (OR 1.9, 95% CI 1.04-3.70, P = 0.04) were associated with a higher risk of CV events. Patients with leucopenia had a higher risk of angina (P = 0.01). CONCLUSIONS pSS is associated with an increased risk of cerebrovascular events and MI. Disease-related clinical and immunological markers may have a role in promoting CV events.

Abstract
The aim of this study was to elucidate more clearly the role of interleukin (IL)-18 in modulating the IL-22 pathway in primary Sjögren's syndrome (pSS) patients and in pSS-associated lymphomas. Minor salivary glands (MSGs) from patients with pSS and non-specific chronic sialoadenitis (nSCS), parotid glands biopsies from non-Hodgkin lymphomas (NHL) developed in pSS patients, were evaluated for IL-18, IL-22, IL-22 receptor 1 (IL-22R1), IL-22 binding protein (IL-22BP) and signal transducer and activator of transcription-3 (STAT-3) expression. MSGs IL-22R1-expressing cells were characterized by confocal microscopy and flow cytometry in pSS, nSCS and healthy controls . The effect of recombinant IL-18 and IL-22 on peripheral blood mononuclear cells (PBMCs) from pSS and nSCS was studied by flow cytometry and reverse transcription-polymerase chain reaction (RT-PCR). MSGs of pSS and NHL were characterized by an imbalance between IL-22 and IL-22BP protein expression, with IL-18 and IL-22BP being expressed in a mutually exclusive manner and IL-18 and IL-22R1 being correlated directly. Aberrant expression of IL-22R1, induced by IL-18, was observed only among tissue and circulating myeloid cells of pSS patients and macrophages of NHL tissues of pSS patients, but not nSCS. IL-22R1 expression on PBMC of pSS was functional, as its stimulation with recombinant IL-22 significantly up-regulated the expression of STAT-3, IL-17 and IL-22. An IL-18-dependent aberrant expression of IL-22R1 on cells of haematopoietic origin seems to be a specific immunological signature of patients with pSS and pSS-associated lymphomas.
