Spondyloarthropathies (SpA) are a group of inflammatory arthritis that can involve the spine and/or peripheral joints. Extra-articular manifestations, such as inflammatory bowel disease (IBD), are frequently observed within the clinical manifestations of SpA and are part of the SpA classification criteria. Evidence of IBD is observed in about 6–7% of SpA patients, and a silent, microscopic gut inflammation, could be present in up to 50% of patients. From a pathogenetic point of view, dysregulated microbiome and migration of T lymphocytes and other cells from gut to the joint ('gut-joint' axis) has been recognized, in the context of a common genetic background. The aim of this paper is to narratively review the recent evidences on the epidemiology, classification, clinical findings, pathogenesis, diagnosis, and treatment of IBD in patients with SpA and to provide advices for both rheumatologist and gastroenterologist in the management of IBD in SpA. IBD manifestations in SpA frequently increase the burden of the disease and represent a clinical challenge, especially for the diagnosis, assessment, and treatment of patients affected by those conditions. New treatment strategies targeting both articular and intestinal manifestations are now available and may lead to a better outcome. [ABSTRACT FROM AUTHOR]

Disproportionate systemic inflammation in chronic obstructive pulmonary disease (COPD) is associated with declining lung functions and comorbidities. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have emerged as valuable markers of the systemic inflammation in COPD. Adiponectin (Acpr30) circulates in serum as complexes of different molecular weight (HMW, MMW, LMW) with multifaceted metabolic and anti-inflammatory properties implicated in airway pathophysiology. We aimed to investigate the association between Acpr30 and its oligomers and the NLR and PLR in COPD patients. Seventy stable COPD patients were enrolled. Acrp30 serum levels and the HMW oligomers as well as hematological parameters and their ratio were evaluated. Both NLR and PLR are associated with lower BMI. Interestingly, total Acpr30 is negatively associated with NLR but not with PLR; after adjusting for age, BMI and FEV1, Acpr30 was independently associated with NLR. Conversely, HMW Acpr30 and HMW/Acpr30 ratio were positively correlated to NLR. The association of Acpr30, HMW Acpr30 and HMW/totalAcpr30 ratio with NLR but not with PLR in COPD patients indicates that Acrp30 oligomerization could represent a biological mechanism interfering with systemic inflammation in COPD. Further studies in larger cohorts of patients are required to confirm these results. [ABSTRACT FROM AUTHOR]

Psoriatic Arthritis (PsA) is a multifaceted disease in which various musculoskeletal and skin manifestations are involved. Beyond these features, PsA is associated with comorbidities that might increase the burden of the disease. In the last years a growing interest has come out for the concept of multimorbidity in rheumatology. Multimorbidity was defined as the 'co-existence of two or more chronic diseases in the same individual.' In the multimorbidity concept, the patient is of central concern and all coexisting diseases are of equal importance. Comorbidity was defined as the 'occurrence of any distinct additional entity during the clinical course of patient who has the index disease under study.' In PsA, comorbidity and multimorbidity have often been confusingly used interchangeably, showing that there is an unmet need on this topic. This perspective article dealt with these different visions of the co-existence of other diseases in PsA, providing a distinction between them, not only for the impact on the treatment decision but also in how this concept might be incorporated into clinical trials design, choosing the right outcome measures for the patient-centric concept of multimorbidity. For this perspective, the authors searched PubMed and the Cochrane library for articles published. [ABSTRACT FROM AUTHOR]

Introduction: Psoriatic Arthritis (PsA) is a chronic inflammatory disease characterized by psoriasis, synovitis, enthesitis, spondylitis, and association with extra-articular manifestations and comorbidities. Treatment of PsA dramatically changed since the introduction of anti-TNF drugs which have shown to reduce the symptoms and signs of the disease and slow the radiographic progression. Despite the introduction of new molecules with different mechanisms of action, the role of anti-TNF in the treatment of all disease manifestations of this intriguing disease is still central. Areas covered: The aim of this paper is to review the role of anti-TNF drugs in the treatment of different disease domains in PsA (peripheral and axial joints, skin, enthesis, patient's reported outcomes, extra-articular manifestations), reporting data from randomized clinical trials and observational studies. An extensive literature search was performed on PubMed, with no limits or filters. The following search terms were used: 'anti-TNF', 'Psoriatic Arthritis'. Expert opinion: Despite the emergence of different new treatments, anti-TNF therapy remains central in the management of all disease domains in PsA patients. [ABSTRACT FROM AUTHOR]

Introduction: Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by the presence of psoriasis, arthritis, and enthesitis, with the association of other musculoskeletal and extra-articular manifestations. Current treatment of PsA is based on the use of conventional, biological and targeted synthetic disease modifying anti-rheumatic drugs; however, patients may not respond or have a loss of response to these agents. Recently, a deeper understanding of the pathogenetic mechanisms has made possible the development of new drugs that actively interact with the activation of immune system, inhibiting the co-stimulation between antigen-presenting cells and lymphocytes. Areas covered: The aim of this paper is to review the role of the activation of the immune system in the pathogenesis and treatment of PsA, with a discussion on the emerging CTLA4Ig drugs (abatacept) for PsA. A search in PubMed and EMBASE was performed with the keywords: ‘abatacept’, ‘CTLA4,’ and ‘Psoriatic Arthritis.’ We considered preclinical studies, phase I, II and III clinical trials. Expert commentary: The inhibitors of co-stimulation may represent an effective treatment strategy by acting on the very early phase of the immunological process that brought about the development of inflammation and activation of the immune system, mainly for patients with peripheral joint involvement and mild psoriasis.

Introduction: Remission or low disease activity should be the target of therapy in spondyloarthritis (SpA). Due to the complexity of the disease, several composite indices that assess all disease domains were proposed to define a status of low disease activity/remission in both axial and peripheral SpA. With the introduction, in the past years, of effective biologic and targeted synthetic treatments aimed at inhibiting key cytokines and intracellular pathways, the goal of clinical remission has become an achievable target in these conditions. However, residual disease activity may occur in some domains and the management of patients that achieve the target of remission is still an unmet need.Areas covered: This manuscript aimed to review the current evidence on clinical remission and residual disease activity in SpA (both axial SpA and psoriatic arthritis), and its potential treatment implications.Expert commentary: Progress in our understanding of the pathogenesis of SpA will lead to a rapid increase in the number of available treatments, with the possibility for patients to achieve a status of remission. However, the topic of residual disease activity should be taken into consideration. [ABSTRACT FROM AUTHOR]

Objective: The aim of the CAMPO-RHE study was to determine the incidence of rheumatoid arthritis (RA), psoriatic arthritis (PsA) and polymyalgia rheumatica (PMR) in patients attending a rheumatologic outpatient's clinic of a new institution in Campobasso, Italy.Methods: Campobasso is a small town of approximately 50,000 inhabitants located in the inland territory of central Italy (Molise), and Public Health is managed from a single health authority. In Italy, all citizens are registered with a National Health System of General Practitioner (GP) Physicians. Between the 1st of June 2014 and the 31st of May 2016, all consecutive adult patients, sent by a GP, of Campobasso with any diagnosis of musculoskeletal symptoms/signs/complaints were evaluated in a single rheumatology outpatient clinic of our Academic Unit. The clinic represents the first and unique reference for GPs about rheumatic diseases in the territory. Subjects were classified using the 2010 EULAR criteria for RA, the CASPAR criteria for PsA and the 2012 ACR classification criteria for PMR.Results: 1003 adult patients, sent by GPs, with articular or musculoskeletal complaints visited our clinic. Of these, 409 inhabitants of the municipality of Campobasso were evaluated for the study. During the 2-year study period we diagnosed 18, 19 and 12 new cases of RA, PsA and PMR respectively, with a new incident cases rate of 21.4, 22.59 and 27.43/100,000/year on the population at risk.Conclusion: The results of our study could contribute to better define the incidence of these rheumatic diseases classified with the new classification criteria.

Introduction: Psoriatic arthritis (PsA) is a chronic inflammatory articular disease characterized by psoriasis, synovitis and enthesitis. Current treatment of PsA is mainly based on the use of classical and biological DMARDs; however, 30–40% of patients could not respond to these or have a loss of response. Areas covered: Recently, the discovery of new pathogenic mechanisms have made possible the development of new drugs that target the IL-17 with the possibility to interfere with the Th17 cells that are considered the cell type mainly involved in the development of the inflammation in PsA. New molecules have shown efficacy and safety over the various components of the disease in randomized clinical trials. These drugs have been recently approved for the treatment of PsA and included in the newest treatment recommendations. Other molecules are currently being tested in phase III clinical trials and are potential new treatment options for PsA. Expert Commentary: The aim of this paper is to review the role of IL-17 in the pathogenesis and treatment of PsA, with a discussion on the emerging anti-IL-17 drugs for PsA. [ABSTRACT FROM AUTHOR]

Objective: The aim of the present study was to assess the rate of sustained Minimal Disease Activity (MDA) and remission in a group of psoriatic arthritis (PsA) patients treated with TNFα blockers.Methods: We perform a retrospective study on our database of PsA patients treated with adalimumab, etanercept and golimumab, with a minimum of 12 months of follow up. Patients were considered in sustained MDA when they met at least 5/7 of the criteria previously defined for at least 12 months of follow up. DAS28-CRP < 2.6, DAPSA score ≤ 4 and patient global assessment (PGA) ≤ 20 mm were also evaluated as remission criteria. Concordance between the remission criteria and MDA was also performed.Results: Of the 81 patients treated with TNFα blockers, at baseline no patients were in MDA or had a DAPSA score ≤ 4, while 17 (20.9%) had a DAS28-CRP score < 2.6. PGA ≤ 20 was recorded in 6 patients (7%). Sustained MDA was achieved in 35 (43.2%) patients while sustained DAPSA, DAS28-CRP and PGA remission were obtained respectively in 19.7%, 35.8% and 44.4% of patients. No difference was found between the three anti-TNFα in respect to the probability of achieve MDA.Conclusions: In this retrospective study, sustained MDA was achieved in 43.2% of patients treated with TNFα blockers. Moreover, sustained remission was achieved in a consistent number of patients, configuring this as an achievable target for PsA patients. [ABSTRACT FROM AUTHOR]
