RESUMO
Background: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disease involving several articular and extra-articular structures. Despite the important progresses recently made in all of the aspects of this disease, its management is still burdened by unresolved issues. The aim of this exercise was to provide a set of statements that may be helpful for the management of PsA. Methods: A group of 38 Italian rheumatologists with recognized expertise in PsA selected and addressed the following four topics: "early PsA," "axial-PsA," "extra-articular manifestations and comorbidities," "therapeutic goals." Relevant articles from the literature (2016-2022) were selected by the experts based on a PubMed search. A number of statements for each topic were elaborated. Results: Ninety-four articles were selected and evaluated, 68 out of the 1,114 yielded by the literature search and 26 added by the Authors. Each of the four topic was subdivided in themes as follows: transition from psoriasis to PsA, imaging vs. CASPAR criteria in early diagnosis, early treatment for "early PsA"; axial-PsA vs. axialspondyloarthritis, diagnosis, clinical evaluation, treatment, standard radiography vs. magnetic resonance imaging for "axial PsA"; influence of inflammatory bowel disease on the therapeutic choice, cardiovascular comorbidity, bone damage, risk of infection for "comorbidities and extra-articular manifestations"; target and tools, treat-to-target strategy, role of imaging for "therapeutic goals." The final document consisted of 49 statements. Discussion: The final product of this exercise is a set of statements concerning the main issues of PsA management offering an expert opinion for some unmet needs of this complex disease.
RESUMO
Objective: To assess the kinetics of the humoral and cell-mediated responses after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in rheumatoid arthritis (RA) patients treated with different immunosuppressive therapies. Methods: Following vaccine completed schedule, health care workers (HCWs, n = 49) and RA patients (n = 35) were enrolled at 5 weeks (T1) and 6 months (T6) after the first dose of BNT162b2-mRNA vaccination. Serological response was assessed by quantifying anti-receptor-binding domain (RBD)-specific immunoglobulin G (IgG) and SARS-CoV-2 neutralizing antibodies, while cell-mediated response was assessed by a whole-blood test quantifying the interferon (IFN)-γ response to spike peptides. B-cell phenotype and IFN-γ-specific T-cell responses were evaluated by flow cytometry. Results: After 6 months, anti-RBD antibodies were still detectable in 91.4% of RA patients, although we observed a significant reduction of the titer in patients under Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4)-Ig [median: 16.4 binding antibody units (BAU)/ml, interquartile range (IQR): 11.3-44.3, p < 0.0001] or tumor necrosis factor (TNF)-α inhibitors (median: 26.5 BAU/ml, IQR: 14.9-108.8, p = 0.0034) compared to controls (median: 152.7 BAU/ml, IQR: 89.3-260.3). All peripheral memory B-cell (MBC) subpopulations, in particular, the switched IgG+ MBCs (CD19+CD27+IgD-IgM-IgG+), were significantly reduced in RA subjects under CTLA-4-Ig compared to those in HCWs (p = 0.0012). In RA patients, a significantly reduced anti-RBD IgG titer was observed at T6 vs. T1, mainly in those treated with CTLA-4-Ig (p = 0.002), interleukin (IL)-6 inhibitors (p = 0.015), and disease-modifying antirheumatic drugs (DMARDs) ± corticosteroids (CCSs) (p = 0.015). In contrast, a weak nonsignificant reduction of the T-cell response was reported at T6 vs. T1. T-cell response was found in 65.7% of the RA patients at T6, with lower significant magnitude in patients under CTLA-4-Ig compared to HCWs (p < 0.0001). The SARS-CoV-2 IFN-γ-S-specific T-cell response was mainly detected in the CD4+ T-cell compartment. Conclusions: In this study, in RA patients after 6 months from COVID-19 vaccination, we show the kinetics, waning, and impairment of the humoral and, to a less extent, of the T-cell response. Similarly, a reduction of the specific response was also observed in the controls. Therefore, based on these results, a booster dose of the vaccine is crucial to increase the specific immune response regardless of the immunosuppressive therapy.

BACKGROUND: [68Ga]Ga-DOTA-NOC binds to somatostatin receptor (SSTR) subtypes 2 and 5, also expressed on lymphocytes and macrophages, but no information is available about uptake in tissues that might be affected by a chronic inflammatory process. Our aim was to obtain normal reference values for: [68Ga]Ga-DOTA-NOC uptake in tissues prone to chronic inflammation. METHODS: Retrospective study in 81 patients who performed the scan for a suspicion of neuroendocrine tumor (NET). We analyzed major joints, salivary glands, thyroid, aortic wall from images acquired after injection of 173.9±1 Mbq of: [68Ga]Ga-DOTA-NOC. We calculated the SUV

OBJECTIVES: Long-term quality of life (QoL) is significantly compromised in patients with psoriatic arthritis (PsA) and only partially improves achieving remission or low disease activity. The main aim of this study is to evaluate the QoL in PsA patients and to investigate their possible relationship with clinical remission and low disease activity, and with its duration over time. METHODS: A multicentre cross-sectional observational study has been performed. QoL domains considered were analysed through PROs. Chi2 test was used for analysis of contingency tables, while Mann-Whitney test and Kruskal-Wallis test with Holm's pairwise comparison corrections were used to compare ranks. To evaluate variables associated to the different QoL domains, univariate and multiple linear regressions were used. RESULTS: 143 participants were included in this study. The physical component of the Short Form-36 or Functional Assessment of Chronic Illness Therapy-Fatigue tends to improve with short duration of low or minimal disease activity. However, this is not confirmed for the mental component of SF-36 (MCS), which improved only with longer duration of low/minimal disease activity. CONCLUSIONS: This study proves the existence of an inverse relation between disease activity and QoL domains. Apart from low or minimal disease activity, also its persistence over time has a great influence on the patient's perception of their clinical condition; therefore, persistence over time of clinical remission/low disease activity should be added to the latest definition of treat-to-target in PsA.

INTRODUCTION AND AIM: Biologic treatment - particularly with the anti-TNF molecules - is frequently used in clinical practice to treat the severe form for both chronic rheumatic diseases and inflammatory bowel diseases. The immunosuppression induced by biologic therapies increases the risk of infections, including tuberculosis, as well as hepatitis B virus (HBV) reactivation may occur in inactive carriers or occult HBV infection (OBI) subjects during biologic therapy. This study aimed to update data on HBV prevalence and reactivation in patients receiving biologic therapy for either chronic rheumatic diseases or IBD, and to describe their management in clinical practice. MATERIALS AND METHODS: This study was performed in 6 Italian centers (3 Rheumatology Units and 3 Gastroenterology Units). Clinical, biochemical and virological data, as well as follow up information, were recorded and analyzed. RESULTS: 984 patients were considered, including 817 with rheumatic disease and 167 with IBD. A total of 43 showed HBV infection (38 OBI and 5 carriers) accounting for a prevalence of 4%. Among OBI patients, 1 (2.6%) case of HBV reactivation occurred in a male patient with Crohn disease. Among the 5 HBV carriers, two patients (1 with spondyloarthritis and 1 with rheumatoid arthritis) did not received HBV antiviral therapy, and both experienced flare of hepatitis at 47 and 49 months following biologic therapy starting. DISCUSSION: Data of our study highlight that guidelines on management of HBV patients treated with biologic therapies should be still implemented in clinical practice when considering that, although infrequent, HBV reactivation could be potentially life-threatening.

Bullous pemphigoid (BP) is an autoimmune blistering skin disease, mainly observed in the elderly. Infections have been suggested as possible disease triggers. However, infections may even heavily influence the disease clinical course and mortality. A 75-year-old woman was admitted to hospital for severe erythematosus blistering disease, accompanied by hyper-eosinophilia and hyper-IgE. The culture of bullous fluid was positive for Enterococcus faecalis, the blood culture was positive for Staphylococcus aureus, and the urine culture was positive for Proteus mirabilis and Escherichia coli. Moreover, circulating anti-BP180 IgG was present and the histopathological/ultrastructural examination of a lesional skin biopsy was compatible with BP. High eosinophil levels (up to 3170/µL) were found throughout the clinical course, while values below 1000/µL were associated with clinical improvement. The total IgE was 1273 IU/mL, and specific anti-G/V-penicillin/ampicillin IgE antibodies were positive. The patient had a complete clinical recovery in two months with methyl-prednisolone (40 then 20 mg/day) and low-dose azathioprine (50 mg/day) as a steroid-sparing agent. The steroid treatment was tapered until interruption during a one-year period and intravenous immunoglobulins have been administered for three years in order for azathioprine to also be interrupted. The patient stopped any treatment five years ago and, in this period, has always been in good health. In this case, the contemporaneous onset of different bacterial infections and BP is suggestive of bacterial infections acting as BP trigger(s), with allergic and autoimmune pathways contributing to the disease pathogenesis.
RESUMO
Phosphodiesterases (PDEs) are a heterogeneous superfamily of enzymes which catalyze the degradation of the intracellular second messengers cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Among PDEs, PDE4 is the most widely studied and characterized isoenzyme. PDE4 blocking can lead to increased levels of intracellular cAMP, which results in down-regulation of inflammatory responses by reducing the expression of tumor necrosis factor (TNF), interleukin (IL)-23, IL-17, interferon-γ, while increasing regulatory cytokines, such as IL-10. Therefore, PDE4 has been explored as a therapeutic target for the treatment of different chronic inflammatory conditions such as psoriatic arthritis (PsA) and inflammatory bowel disease (IBD). PsA shares clinical, genetic, and pathogenic features with IBD such as ulcerative colitis (UC) and Crohn's disease (CD), and enteropathic spondyloarthritis (eSpA) represent a frequent clinical evidence of the overlap between gut and joint diseases. Current therapeutic options in PsA patients and underlying UC are limited to synthetic immunosuppressants and anti-TNF. Apremilast is an oral PDE4 inhibitor approved for the treatment of active PsA patients with inadequate response to synthetic immunosuppressants. The efficacy and a good safety profile observed in randomized clinical trials with apremilast in PsA patients have been confirmed by few studies in a real-life scenario. In addition, apremilast led to significant improvement in clinical and endoscopic features in UC patients in a phase II RCT. By now there are no available data regarding its role in eSpA patients. In view of the above, the use of apremilast in eSpA patients is a route that deserves to be deepened.

BACKGROUND: The aim of this study was to report the first case of acute facial allograft transplantation (facial allograft transplantation) failure with allograft removal and autologous free-flap reconstruction. METHODS: A 49-year-old female patient affected by neurofibromatosis type 1 with a massive neurofibroma infiltrating the whole left hemiface was planned for FAT for the left hemiface including the auricle, all skin and soft tissues from the temporal region, periorbital and nasal region, and up to the perioral area. The maxillary process of the zygomatic bone, left hemimaxilla, and hemimandible from contralateral parasyphysis to the incisura mandibulae were also included. RESULTS: Total surgical time was 26 hours. There were 2 intraoperative arterial thromboses that were solved with new anastomoses and sufficient flap perfusion. On postoperative day 2, the allograft became pale with suspected arterial occlusion and the patient returned to the operative room for exploration no flow into the FAT was found. The allograft was removed and the recipient site reconstructed with a skin-grafted composite left latissimus dorsi-serratus anterior flap. CONCLUSIONS: Hyperacute loss of FAT is a very dramatic event, and the activation of a backup surgical plan is crucial to save patient's life, give a reasonable temporary reconstruction, and return on the waiting-list for a second face transplantation.

OBJECTIVE: Spondyloarthritis (SpA) is among the most frequent extraintestinal manifestations of inflammatory bowel diseases (IBD). In this study, we aimed to validate the DETection of Arthritis in Inflammatory boweL diseases (DETAIL) questionnaire in a multicenter cohort of patients with IBD enrolled at 11 gastroenterology units. METHODS: From October 2018 to March 2019, consecutive adult patients with IBD, either Crohn disease or ulcerative colitis, independently filled out the DETAIL questionnaire in the outpatient waiting room. Within 2 weeks a blinded rheumatologist assessed all the patients, irrespective of the DETAIL results, and classified them to be affected or not by SpA. The performance of the questions was evaluated through Bayesian analysis. RESULTS: Overall, 418 patients with IBD filled out the DETAIL questionnaire. Upon rheumatological evaluation, 102 (24.4%) patients received a diagnosis of SpA. Of the 6 questions, the best performances were found in question 6 [positive likelihood ratio (LR)+ 3.77], reporting inflammatory back pain at night, and in question 3 (LR+ 3.31), exploring Achilles enthesitis. The presence of back pain lasting > 3 months (LR+ 2.91), back pain with inflammatory features (LR+ 2.55), and a history of dactylitis (LR+ 2.55), also showed a fairly good performance, whereas a history of peripheral synovitis was slightly worse (LR+ 2.16). The combination of at least 3 questions answered affirmatively yielded a posttest probability of SpA of 80% or more. The presence of alternative diagnoses, such as osteoarthritis or fibromyalgia, represented a minor confounder. CONCLUSION: The DETAIL questionnaire is a useful tool for the early detection of SpA in IBD.

BACKGROUND: Secukinumab (SEC) is effective for ankylosing spondylitis (AS) and psoriatic arthritis (PsA) in randomized trials, but real-life data are lacking. RESEARCH DESIGN AND METHODS: Real-life, prospective observational study on 169 consecutive outpatients at baseline (T0) and at 6 (T6) and 12 months (T12) after starting SEC (39 AS, 23%; 130 PsA, 77%). RESULTS: Significant improvement was seen at T6 and T12 for all clinical variables, including TJC, SJC, ESR, CRP, DAPSA, ASDAS-CRP, and BASDAI, as well as in patient-reported outcomes like VAS-pain. By multivariable regression analysis, in AS patients high BASDAI at T0 correlated with diagnostic delay (R2 = 0.4; p = 0.009) and peripheral joint involvement (R2 = 0.4; p = 0.04). During follow-up, reduction of BASDAI positively correlated with high ESR (R2 = 0.65; p = 0.04). ASDAS-CRP at T0 positively correlated with high ESR (R2 = 0.34; p = 0.004). Reduction of ASDAS-CRP from T0 to T6 correlated with current smoking status (R2 = 0.42; p = 0.003). In PsA patients, reduction of DAPSA score from T0 to T12 is negatively correlated with the presence of metabolic syndrome (R2 = 0.41; p = 0.0025). SEC was well tolerated; 10 patients discontinued treatment for non-severe adverse events. CONCLUSIONS: Secukinumab is effective and safe in patients with AS and PsA in a real-life setting.

BACKGROUND: Polypharmacy exposes patients with comorbidities (particularly elderly patients) to an increased risk of drug-specific adverse events and drug-drug interactions. These adverse events could be avoided with the use of a computerized prescription support system in the primary care setting. The INTERCheck® software is a prescription support system developed with the aim of balancing the risks and benefits of polytherapy and examining drug-drug interactions. OBJECTIVES: This observational study used the INTERCheck® software to evaluate the incidence of adverse events and of drug-drug interactions in outpatients and inpatients receiving multiple medications. METHODS: Patients were randomly enrolled from the outpatient department (n = 98) and internal medicine ward (n = 46) of S. Andrea Hospital of Rome. Polypharmacological treatment was analyzed using INTERCheck® software, and the prevalence of risk indicators and adverse events was compared between the two groups. RESULTS: Polypharmacy (use of five or more drugs) applied to all except three cases among outpatients and one case among inpatients. A significant positive correlation was found between the number of medications and the INTERCheck® score (ρ = 0.67; p < 0.000001), and a significant negative correlation was found between the drug-related anticholinergic burden and cognitive impairment (r = - 0.30 p = 0.01). Based on the INTERCheck® analysis, inpatients had a higher score for class D (contraindicated drug combination should be avoided) than did outpatients (p = 0.01). The potential class D drug-drug interactions were associated with adverse events that caused hospitalization (χ2 = 7.428, p = 0.01). CONCLUSIONS: INTERCheck® analysis indicated that inpatients had a high risk of drug-drug interactions and a high percentage of related adverse drug events. Further prospective studies are necessary to evaluate whether the INTERCheck® software may help reduce polypharmacy-related adverse events when used in a primary care setting and thus potentially avoid related hospitalization and severe complications such as physical and cognitive decline.
RESUMO
INTRODUCTION: Spondyloarthrits (SpA) share clinical, genetic and immunological features with Inflammatory Bowel Diseases (IBD), and enteropathic SpA (eSpA) represent the clinical evidence of the association between gut and joint diseases. This cross-sectional study aimed to report data of eSpA patients collected from the first Italian database. PATIENTS AND METHODS: A specific web-based interface has been created to insert and collect the main clinical, serologic and imaging data from patients with eSpA, as well as disease activity, comorbidities and treatment, in a real-life scenario. RESULTS: Data were collected in 14 Italian centers (7 rheumatology and 7 gastroenterology units). A total of 347 eSpA patients were enrolled in the study. Type 1 peripheral eSpA was the most frequent form. Crohn' Disease (CD) was the most represented IBD. CD activity was similar among eSpA, whereas UC activity was slightly higher in the axial and mixed form than in the peripheral eSpA. The disease was active in less than half of axial eSpA patients and in only 18% of patients with peripheral eSpA. Furthermore, most of the patients had an inactive IBD. Nineteen percent of the total eSpA patients were free of therapy at the time of the enrollment and 61% of the patients were receiving biotechnological agents. CONCLUSIONS: The multidisciplinary management of eSpA patients, favored by this ad hoc created web-based platform, allowed to obtain data from the largest eSpA cohort. The information coming of this database might advance knowledge of eSpA and improve their standard of care.

Diet is a modifiable factor implicated in chronic systemic inflammation, and the mediterranean dietary pattern is considered to be a healthy model in terms of morbidity and mortality. The main aim of this study was to evaluate the adherence to the mediterranean diet in patients with Psoriatic Arthritis (PsA) and its impact on disease activity. A cross-sectional observational study was conducted in a cohort of 211 consecutive PsA patients. We evaluated PsA activity by disease activity index for PSoriatic Arthritis (DAPSA) and composite psoriatic disease activity index (CPDAI). The NCEP-ACT III criteria were used to identify subjects with MetS, and in each subject, we evaluated body mass index (BMI). A validated 14-item questionnaire for the assessment of adherence to the mediterranean diet (PREDIMED) was recorded for all the enrolled subjects. Patients showed a median age of 55 (48-62) and diseaseâ¯duration was 76 (36-120) months. 27.01% of patients were classified as having MetS. The median of the mediterranean diet score (MDS) was 7 (6-9). A moderate adherence to mediterranean diet was found in 66.35% of the entire cohort; 15.64% and 18.01% of the patients showed low- and high adherence to the dietary pattern, respectively. We found a negative association between DAPSA and adherence to mediterranean diet (B = - 3.291; 95% CI - 5.884 toâ¯- 0.698). DAPSA was positively associated with BMI (B = 0.332; 95% CI 0.047-0.618) and HAQ ( B = 2.176; 95% CI 0.984-3.368). Results from our study evidenced that in PsA patients, higher levels of disease activity as measured by DAPSA correlated with low adherence to mediterranean diet, suggesting potential benefit of antinflammatory properties of this dietary pattern.

A certain number of studies were carried out to address the question of how dysbiosis could affect the onset and development of rheumatoid arthritis (RA), but little is known about the reciprocal influence between microbiota composition and immunosuppressive drugs, and how this interaction may have an impact on the clinical outcome. The aim of this study was to characterize the intestinal microbiota in a groups of RA patients treatment-naïve, under methotrexate, and/or etanercept (ETN). Correlations between the gut microbiota composition and validated immunological and clinical parameters of disease activity were also evaluated. In the current study, a 16S analysis was employed to explore the gut microbiota of 42 patients affected by RA and 10 healthy controls. Disease activity score on 28 joints (DAS-28), erythrocyte sedimentation rate, C-reactive protein, rheumatoid factor, anti-cyclic citrullinated peptides, and dietary and smoking habits were assessed. The composition of the gut microbiota in RA patients free of therapy is characterized by several abnormalities compared to healthy controls. Gut dysbiosis in RA patients is associated with different serological and clinical parameters; in particular, the phylum of Euryarchaeota was directly correlated to DAS and emerged as an independent risk factor. Patients under treatment with ETN present a partial restoration of a beneficial microbiota. The results of our study confirm that gut dysbiosis is a hallmark of the disease, and shows, for the first time, that the anti-tumor necrosis factor alpha (TNF-α) ETN is able to modify microbial communities, at least partially restoring a beneficial microbiota.

Immunogenicity of 13-valent pneumococcal polysaccharide (PnPS) conjugate vaccine (PCV13) was evaluated in 38 rheumatoid arthritis patients under immunosuppressive treatment and 20 healthy controls (HC). Antibodies to all PnPS and diphtheria-toxin analogue conjugate protein were measured pre- (T0), 1 (T1), 6 (T2), 12 (T3) months post-immunization. Patients and HC had similar response to individual PnPS. Mean antibody levels to all PnPS but one doubled at T1 compared with T0, with T3 persistence for only 8-7/13 PnPS. Baseline antibody levels was inversely associated with the rate of responders at T1 (T1/T0≥2) to 11/13 PnPS. Few subjects reached protective IgG levels against some serotypes frequently isolated in Italian patients with invasive pneumococcal disease. Antibody response was not influenced by therapy, except the one to PS7F, which was reduced by tumor necrosis factor-α-inhibitors. Vaccination increased also anti-diphtheria IgG. Despite this study substantially confirmed the PCV13 immunogenicity in immunocompromised patients, it also revealed some limitations.

BACKGROUND: Lymphocyte expansion and true lymphocytosis are commonly observed in the everyday clinical practice. The meaning of such phenomenon is often poorly understood so that discrimination between benign and malignant lymphocytosis remains difficult to establish. This is mainly true when lymphocytosis rises in patients affected by immune-mediated chronic inflammatory diseases under immunosuppressive treatment, conditions potentially associated with lymphomagenesis. In this brief report the development of mild T CD4pos lymphocytosis in a group of patients with chronic arthritis under anti-TNF-α treatment is described. METHODS: Two hundred eight rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients have been evaluated longitudinally for at least 1-year before and 2-years after anti-TNF-α therapy introduction for the possible appearance of a lymphocyte expansion. In patients who developed lymphocyte expansion, T, B and NK cells were analysed. RESULTS: Twenty-five out of 208 (12%) subjects developed a mild T CD4pos lymphocytosis, during anti-TNF-α therapy, which reverted after its interruption. Higher lymphocyte count, more frequent use of steroids and shorter disease duration, before biological therapy start, have emerged as risk factors for lymphocytosis development. CONCLUSIONS: This is the first longitudinal cohort study evaluating the onset of lymphocytosis in RA and PsA patients under anti-TNF-α treatment and its possible clinical relevance. A mild T CD4pos lymphocytosis has been observed in 12% of RA and PsA patients probably related to anti-TNF-α treatment as previously reported by anecdotal cases. Patients with higher baseline lymphocyte count, use of steroids and shorter disease duration before the introduction of biologic therapy, seem to be prone to develop this laboratory reversible abnormality.

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that can present different extrarticular manifestations involving heart, lungs and kidneys. In recent years there has been a growing awareness of the central role played by the lungs in the onset and progression of RA. In particular interstitial lung disease (ILD) is a common pulmonary manifestation that may be related to the inflammatory process itself, infectious complications and to the treatments used. Management of patients with ILD/RA is still a challenge for clinicians, both synthetic [mainly methotrexate (MTX), leflunomide] and biologic immunosuppressors [mainly anti-tumor necrosis factor (TNF)α] have in fact been related to the onset or worsening of lung diseases with conflicting data. Here we report the case of a 61-year-old male patient with severely active early RA, previously treated with MTX, who developed subacute ILD, along with a review of ILD/RA topic. Tocilizumab (humanized monoclonal antibody against the interleukin-6 receptor) was introduced on the basis of its effectiveness in RA without concomitant MTX and the ability to overcome the profibrotic effects of interleukin (IL)-6. After 3 months of treatment the clinical condition of the patient strongly improved until it reached low disease activity. He no longer complained of cough and dyspnea and bilateral basal crackles were no more present. Considering its distinctive features, tocilizumab, in such a challenging clinical condition, appears to be a safe and effective therapy, thus it enables RA remission without deteriorating ILD, at 1-year follow up, as confirmed by ultrasonography of the affected joints and chest high-resolution computed tomography (HRCT).

BACKGROUND: Primary immunodeficiencies (PIDs) are generally characterized by recurrent infections; however they may be complicated by other clinical disorders such as allergy, autoimmunity, and lymphoproliferation. In particular, autoimmunity may be the first manifestation of the disease in patients with low serum immunoglobulins (Ig) levels. Here we describe a group of patients that share features of immunodeficiency and autoimmunity. MATERIALS AND METHODS: All patients went through a complete T and B cell subset characterization and a B cell function analysis in the peripheral blood by flow-cytometry. B cell proliferation and plasma cell differentiation was measured, in vitro, after CpG stimulation for 7 days as previously described. Semi-quantitative PCR analysis for AID and UNG expression as well as serum levels of BAFF were carried out in order to better define the diagnosis. RESULTS: Immunological and molecular analysis did not lead to the identification of known molecular defect typical of Hyper IgM syndrome. A comparative study of the peripheral blood B cell subsets between patients and healthy donors showed that in patients with autoimmune manifestations all circulating B cells expressed high amounts of surface IgM. CONCLUSIONS: These results suggest that the increased IgM expression on circulating B cells, reflecting B cell activation, might identify a clinical condition characterized by hyper IgM serum levels of unknown molecular defects, associated with susceptibility to infections and autoimmunity.

BACKGROUND AND OBJECTIVE: There are four efficacious subcutaneous anti-tumor necrosis factor alpha (TNF-alpha) agents used for the therapy of ankylosing spondilitis (AS), but apparently little or no differences in their effectiveness was proven. By this study, we aimed to compare Assessment in Ankylosing Spondylitis Response Criteria 20 response patterns (ASAS20) between subcutaneous approved biological agents in patients affected by ankylosing spondylitis by means of a mixed treatment comparison of different randomized controlled trials (RCTs) on the efficacy of biological therapies. METHODS: A search in scientific literature was performed to identify the most complete collection of RCTs available on the selected topic. Similarly designed double-blind, randomized, placebo-controlled trials investigating the efficacy of the subcutaneous and approved TNF-alpha inhibitors such as etanercept, certolizumab pegol, golimumab and adalimumab in the treatment of ankylosing spondylitis patients were identified. The endpoint of interest was ASAS20 response criterium at 12 weeks. Results were analysed simultaneously using Bayesian mixed treatment comparison techniques. Results were expressed as odds ratio (OR) of positive ASAS20 response and associated 95 % credible intervals (CrIs). The probability of being the best treatment was also reported. RESULTS: Only five RCTs matched the inclusion criteria for consequent data extraction and analysis. Mixed treatment comparison of data from such RCTs demonstrated that all subcutaneous anti-TNF-alpha agents are more effective in inducing an ASAS20 response than placebo. Data from 24 weeks' follow-up were not taken into account as early escape granted in some of the studies made results at 24 weeks unmatchable. In our analysis, golimumab proved to be the drug that more probably represents the best choice for achieving ASAS20 response at 12 weeks, although no differences were observed when comparing directly every single subcutaneous anti-TNF-alpha agent against another. CONCLUSIONS: Even if the mixed treatment comparisons between adalimumab, golimumab, certolizumab pegol and etanercept did not show a statistically significant difference, this analysis, based on data from only five RCTs, suggests that golimumab, compared to placebo, may be the drug that provides the highest probability of achieving ASAS20 response in AS patients naive to biologic treatments at 12 weeks.

OBJECTIVE: Treatment with tumour necrosis factor antagonists (anti-TNF) has been recognized as a risk factor for tuberculosis (TB) reactivation. Our aim was to evaluate risk of TB reactivation in rheumatologic and non-rheumatologic diseases treated with the same anti-TNF agents with and without concomitant therapies. METHODS: We searched for randomized controlled trials (RCTs) evaluating infliximab, adalimumab, and certolizumab in both rheumatologic and non-rheumatologic diseases until 2012. Results were calculated as pooled rates and/or pooled odd ratios (OR). RESULTS: Overall, 40 RCTs with a total of 14,683 patients (anti-TNF: 10,010; placebo: 4673) were included. TB reactivation was 0.26% (26/10,010) in the anti-TNF group and 0% (0/4673) in the control group, corresponding to an OR of 24.8 (95% CI 2.4-133). TB risk was higher when anti-TNF agents were combined with methotrexate or azathioprine as compared with either controls (24/4241 versus 0/4673; OR 54; 95% CI 5.3-88) or anti-TNF monotherapy (24/4241 versus 2/5769; OR 13.3; 95% CI 3.7-100). When anti-TNF was used as monotherapy, TB risk tended to be higher than placebo (2/5769 versus 0/4673; OR 4; 95% CI 0.2-15.7). CONCLUSIONS: TB risk with anti-TNF agents appeared to be increased when these agents were used in combination with methotrexate or azathioprine as compared with monotherapy regimen. TB risk seemed to be higher than placebo, even when monotherapy is prescribed.
