Systemic sclerosis (SSc) is a heterogeneous chronic autoimmune disease that it is very difficult to diagnose in the early phase, resulting in a critical delay in therapy which is often begun when internal organ involvement is already irreversible. The ACR or LeRoy criteria have a low sensitivity for the early phases; these criteria were replaced by the ACR/EULAR 2013 criteria which improved the disease classification. Therefore, the SSc diagnosis may be delayed for several years after the onset of Raynaud’s phenomenon (RP) and even after the onset of the first non-RP symptom. RP, antinuclear antibodies (ANA) positivity, and puffy fingers were recently indicated as “red flags” (by the VEDOSS project) – that is, the main elements for suspicion of SSc in the very early phase of the disease. Confirming the diagnosis requires further tests, particularly nailfold videocapillaroscopy and evaluation of specific disease antibodies (anti-centromere and anti-topoisomerase I). In this way, the VEDOSS project identified patients in the very early phase of disease enabling a ‘‘window of opportunity’’ whereby the physician can act with effective drugs to block or at least slow the progression of the disease. The principal challenge in the fight against SSc is to detect valid predictors of disease evolution in order to treat patients in the early stage of disease. While waiting to find valid predictors, a close follow-up of the patients with the VEDOSS red flags is essential, as is a close collaboration between rheumatologists and general practitioners in order to identify all potential SSc patients as soon as possible.

Physical, mental and social well-being are important outcomes in patients with chronic rheumatic diseases, including systemic lupus erythematosus (SLE). The MOS SF-36 and the WHO QoL Bref are appropriate for assessing quality of life (QoL) in patients with SLE. The QoL of patients with SLE is impaired compared with that of controls. Fibromyalgia adversely affects the QoL of SLE patients. Women with SLE had significantly lower scores on subscales of the sense of coherence (SoC) compared with matched controls. This reduced SoC in SLE women represents impaired adaptive coping and is independently associated with reduced QoL in women with SLE. Depression and anxiety are common among SLE patients, and the frequency is similar to that in patients with rheumatoid arthritis. A reciprocal longitudinal relationship between depression and illness intrusiveness was found in patients with SLE. Disease activity and damage are not associated with depression. The subjective experience, not the illness per se, causes depression.

Background: Antiphospholipid antibodies (aPL) have been advocated as potential mediators of unexplained female infertility, but no evidence has yet been raised to support such an association.
Objectives: To test the hypothesis that aPL might interfere with uterine decidualization, a gene expression study was performed on decidual stromal cells treated with different aPL preparations.
Methods: Decidual stromal cells were isolated from first-trimester deciduas obtained from two women undergoing elective abortion, and treated with: (i) a β2GPI-dependent aPL monoclonal antibody (IS3); (ii) IS3 plus TIFI, a synthetic peptide mimicking PL-binding region of β2GPI; and (iii) IgG from healthy subjects (NHS). Gene expression data were acquired using human HT-12 v3 beadchip arrays (Illumina). Differential expression analysis was performed by fitting a gene-wise linear model using the treatment group and decidual source as covariates.
Results: In the comparison of IS3 versus IgG NHS-treated decidual cells, gene ontology (GO) enrichment was expressed in terms relating to well-characterized aPL-mediated cellular effects: “inflammatory response,” “immune response,” “response to stress,” “oxydoreductase activity,” “metalloendopeptidase activity,” and “cytokine/chemokine activity.” As expected, almost all genes were up-regulated by IS3 treatment. The same GO categories appeared to be differentially expressed when IS3 treatment was compared to IS3 + TIFI, but with most genes being down-regulated.
Conclusions: Given the inflammatory response evinced at gene expression analysis on decidual stromal cells treated with a β2GPI -dependent aPL monoclonal antibody, it is feasible that aPL might interfere with uterine decidualization, affecting the early stages of implantation and ultimately resulting in female infertility.

Sjögren’s syndrome (SS), a chronic systemic autoimmune inflammatory condition involving the exocrine glands, has been suggested to be part of the spectrum of the “Autoimmune/inflammatory Syndrome Induced by Adjuvants” (ASIA). ASIA incorporates an umbrella of clinical conditions including siliconosis, macrophage myofasciitis syndrome, and post-vaccination phenomena that occur after the exposure to a substance, namely the adjuvant. Interestingly, SS and ASIA share several common features. Firstly, a shared pathogenic mechanism involving a disruption of the immune system balance, with B cell proliferation, cytokine production and tissue infiltration, have been proposed. Patients with ASIA often present clinical features resembling those of SS; dry mouth and dry eyes have also been included in the proposed classification criteria for ASIA. Finally, several case reports have suggested that both vaccines and silicone may trigger the development of SS. Unveiling these common pathways will contribute considerably to our understanding and managing of both conditions.

Lung involvement is a well-recognized extra-articular manifestation of ankylosing spondylitis (AS). Anecdotal reports suggest that the use of anti-TNF drugs may be related to lung disease and pulmonary fibrosis. To examine the association between anti-TNF drugs and the development of lung disease in patients with AS or psoriatic arthritis (PsA) we conducted a systematic review. Of the 670 papers identified by means of key word and hand search, only one full-text paper was considered potentially relevant but had to be discarded as it did not meet the eligibility criteria. Although no conclusion was reached, this is the first systematic review to examine this problem which is becoming increasingly important as these drugs are widely prescribed in patients with spondyloarthritis.

Long-term extension studies and observational drug registers have revealed an increased risk of serious infections in patients treated with anti-tumor necrosis factor agents, particularly infliximab, etanercept and adalimumab. The same may be true for the newer biological drugs rituximab, tocilizumab and abatacept, although this has yet to be confirmed by long-term observational studies. We review the risk of tuberculosis, herpes zoster and other opportunistic infections, and the recommendations for screening for tuberculosis and hepatitis B and C infections in patients affected by rheumatoid arthritis, with the aim of informing patients and encouraging greater awareness among physicians.

Behçet’s disease (BD) is a systemic inflammatory disorder characterized by a protean clinical spectrum and an enigmatic pathogenesis. After being classified as an autoimmune disorder, spondyloarthritis and vasculitis, today BD is considered at the crossroad between autoimmune and auto-inflammatory syndromes. Many pathogenetic, clinical and therapeutic clues support this recent interpretation, enabling novel treatment choices such as interleukin (IL)-1 inhibition. Thus, in the last decade the IL-1 receptor antagonist anakinra and the anti-IL-1β monoclonal antibody canakinumab were increasingly administered in BD patients resistant to standard therapies, leading to interesting results and new intriguing pathogenetic implications. However, further studies are essential to both establish how the innate and acquired immune systems interact in BD patients and identify the best way of administering anti-IL-1 agents with regard to dosage, interval of administration and organ response.

There is growing interest in the contribution of vitamin D deficiency to autoimmunity. Several studies have shown an association between low levels of vitamin D and autoimmune disorders, including multiple sclerosis, rheumatoid arthritis, type 1 diabetes, autoimmune thyroid diseases, celiac disease, and systemic lupus erythematosus (SLE). Vitamin D receptor ligands can mediate immunosuppressive effects. It has been suggested that low levels of this hormone contribute to the immune activation in lupus and other autoimmune diseases. This review updates and summarizes the literature on the association between vitamin D and SLE, and discusses the various correlations between vitamin D and SLE activity, clinical expressions, serology, and gene polymorphisms of vitamin D receptors.

Autoimmune rheumatic diseases (ARD) affect mainly young women during their reproductive years. Fertility is usually not diminished but the time it takes to conceive is usually longer. Factors related to an ARD or to its treatment are responsible for this effect. In addition, contraception counseling is required to prevent negative fetal outcome and exacerbation of disease symptoms. In recent years, advances in therapies, clarification of risk factors for adverse pregnancy outcomes, and a multidisciplinary approach have vastly improved obstetric management, increasing the possibility of successful pregnancy with a high likelihood of favorable outcome.

Background: Radiation-induced dermatitis is commonly seen during radiotherapy for breast cancer. Melatonin-based creams have shown a protective effect against ultraviolet-induced erythema and a radioprotective effect in rats.
Objectives: To evaluate the efficacy of melatonin-containing cream in minimizing acute radiation dermatitis.
Methods: In this phase II, prospective, randomized, placebo-controlled double-blind study, patients who underwent breast-conserving surgery for stage 0-2 breast cancer were randomly allocated to melatonin emulsion (26 women) or placebo (21 women) for twice daily use during radiation treatment and 2 weeks following the end of radiotherapy. All women received 50 Gy whole breast radiation therapy with 2 Gy/fx using computed tomography-based 3D planning. Patients were examined and completed a detailed questionnaire weekly and 2 weeks following the end of treatment.
Results: The occurrence of grade 1/2 acute radiation dermatitis was significantly lower (59% vs. 90%, P = 0.038) in the melatonin group. Women older than 50 had significantly less dermatitis than younger patients (56% vs. 100%, P = 0.021). The maximal radiation dermatitis in the study group was grade 2 in 15% of the treated patients.
Conclusions: Patients treated with melatonin-containing emulsion experienced significantly reduced radiation dermatitis compared to patients receiving placebo.
