Identifying the symptom and functional domains in patients with fibromyalgia: results of a cross-sectional Internet-based survey in Italy.

Objective: The aims of this cross-sectional study were to investigate the usefulness of using an Internet survey of patients with fibromyalgia in order to obtain information concerning symptoms and functionality and identify clusters of clinical features that can distinguish patient subsets.

Methods: An Internet website has been used to collect data. Fibromyalgia Impact Questionnaire Revised version, self-administered Fibromyalgia Activity Score, and Self-Administered Pain Scale were used as questionnaires.

Infections and Biological Therapy in Patients with Rheumatic Diseases.

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 with rheumatoid arthritis, with the aim of informing patients and encouraging greater awareness among physicians.

Do Anti-TNF Blockers Increase the Risk of Lung Involvement in Patients with Ankylosing Spondylitis or Psoriatic Arthritis? A Systematic Review.

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.

One year in review 2016: fibromyalgia.

Fibromyalgia (FM) syndrome is a chronic disease with unknown aetiology, characterised by widespread pain, fatigue and other functional symptoms. We reviewed the literature of the past year to underline the recent progress in the etiopathogenesis, assessment and therapies of this syndrome, evaluating the articles published between January 2015 and January 2016.

Impaired lung transfer factor in fibromyalgia syndrome.

Objectives: The aim of this study was to evaluate whether pulmonary diffusing capacity is impaired in patients with fibromyalgia (FM) as it is in those with other diseases characterised by autonomic nerve system (ANS) dysfunction such as type 1 diabetes.

Methods: Forty-five consecutive anti-nuclear antibody (ANA)-negative female Caucasian patients aged 50.1± 5.

Is panic disorder associated with clinical severity of fibromyalgia? A preliminary study in a tertiary-care centre.

Objectives: To investigate the influence of panic disorder (PD) with/without agoraphobia on the clinical severity of fibromyalgia (FM).

Methods: Eighty-one patients with FM, among those consecutively referring to a tertiary-care setting, were included in this cross-sectional study. Psychiatric diagnoses were made by the structured clinical interview in accordance with the 4th-TR version of the diagnostic and statistical manual of mental disorders.

Reactivation of occult hepatitis B virus infection under treatment with abatacept: a case report.

Background: Abatacept (ABA) is a fusion receptor protein containing the CTLA-4 domain that prevents the activation of naïve T cells by binding the CD80 and CD86 molecules expressed on the surface of dendritic cells, indicated for the treatment of moderate to severe rheumatoid arthritis (RA). There is still little evidence concerning the safety of ABA in RA patients with positive serology for hepatitis virus B (HBV) infection.

Case Presentation: We report the case of a HBV infection reactivation in an ABA-treated male RA patient.

Correlations between immunogenicity, drug levels, and disease activity in an Italian cohort of rheumatoid arthritis patients treated with tocilizumab.

The aim of this study was to evaluate the real-life immunogenicity of anti-drug antibodies, drug levels, and disease activity in an Italian cohort of rheumatoid arthritis patients treated with tocilizumab (TCZ). We evaluated 126 TCZ-treated patients with rheumatoid arthritis (16 males and 110 females; mean age 59±12 years, range 26-83; mean disease duration 11±5 years) with inadequate 12-week response to any synthetic and biological disease-modifying anti-rheumatic drugs, in a retrospective analysis. One-hundred and seven patients were treated with methotrexate mean dose 12.

Costs associated with rheumatoid arthritis in Italy: past, present, and future.

This literature review examines available evidence on the current and past costs associated with rheumatoid arthritis (RA) in Italy, together with the future health-economic prospects for the disease. Studies have been conducted to date on the prevalence, or the associated costs, of RA in Italy. Although future changes in the incidence of RA are a matter of debate, the impact of RA on health care costs is expected to grow in coming decades in line with projected increases in life expectancy and in the proportion of elderly people in Italy.

Diffusing Pulmonary Capacity Measured During Effort: A Possible Early Marker of Pulmonary Involvement In Systemic Sclerosis.

Background: Interstitial lung involvement is common and potentially limits the quality of life in patients with systemic limited sclerosis (SScl).

Objectives: To study the lung carbon monoxide diffusion (DLCO) measured during effort in order to identify a possible subclinical impairment.

Methods: We enrolled 20 SScl patients without interstitial lung involement and 20 healthy controls.

Low Risk of Hepatitis B Virus Reactivation in HBsAg-negative/Anti-HBc-positive Carriers Receiving Rituximab for Rheumatoid Arthritis: A Retrospective Multicenter Italian Study.

Objective: Patients with resolved hepatitis B virus (HBV) infection, i.e., hepatitis B surface antigen (HBsAg)-negative/antihepatitis B core antigen (anti-HBc)-positive, undergoing rituximab (RTX)-based chemotherapy for hematological malignancies without anti-HBV prophylaxis are at risk of HBV reactivation, but the risk in such patients receiving RTX for rheumatological disorders is not clear.

Novel pharmaceutical options for treating fibromyalgia.

Fibromyalgia is a chronic disorder whose symptoms have a devastating effect on patients' lives as they limit their ability to engage in everyday working and social activities, and make it difficult to maintain normal relationships with family, friends and employers. None of the currently available drugs are fully effective against the whole spectrum of symptoms of pain, fatigue, sleep disturbances and depression, but increasing efforts by the pharmaceutical industry have led to the introduction of new investigational drugs and new formulations of older drugs, as well as studies of the possibility of applying drugs currently used for other diseases. The aim of this review is to summarise the data relating to the new therapeutic options that have become available over the last few years.

Serological epitope profile of anti-Ro52-positive patients with systemic autoimmune rheumatic diseases.

Background: Ro52 is an interferon-inducible protein of the tripartite motif family. Antibodies against Ro52 have been described in patients with different autoimmune diseases, such as systemic lupus erythematosus and Sjögren's syndrome, that are often associated with anti-Ro60 antibodies. The Ro52 autoantigen is extraordinarily immunogenic, and its autoantibodies are directed against both linear and conformational epitopes.

Safety of Abatacept in Rheumatoid Arthritis With Serologic Evidence of Past or Present Hepatitis B Virus Infection.

Objective: Rheumatoid arthritis (RA) with concomitant hepatitis B virus (HBV) infection represents a therapeutic challenge due to the risk of HBV reactivation under immunosuppressive treatment. To date there are few data coming from anecdotal case reports that concern HBV reactivation following treatment with abatacept. This observational retrospective study was aimed to assess the safety profile of abatacept in this particular clinical setting.

Role of Agents other than Tumor Necrosis Factor Blockers in the Treatment of Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a systemic inflammatory disease characterized by possible peripheral and axial joint involvement, enthesitis, dactylitis, and skin and nail disease. It affects up to one-third of psoriatic patients, and may be associated with comorbidities such as cardiovascular and metabolic diseases. The usually prescribed initial treatment of moderate-severe PsA is methotrexate, which may be accompanied or replaced by a tumor necrosis factor (TNF) inhibitor such as etanercept, infliximab, or adalimumab.

Psoriatic Arthritis Registries.

The introduction of new biological drugs for the treatment of rheumatoid arthritis and spondyloarthritis has led to the creation of a number of registries in Europe and the United States. Most of them are sponsored by national rheumatology societies, and provide information that is useful in clinical practice concerning the clinical characteristics, efficacy, and safety of all licensed biological drugs. Their findings also help to improve our understanding of the quality of life and working ability of patients receiving biological drugs, and suggest methods for allocating resources.

Significance of serum Il-9 levels in inflammatory bowel disease.

IL-9, which may be an inflammatory or regulatory cytokine, can be experimentally produced in a Th17 or modified Th2 context in the presence of T cell receptor (TCR) stimulation. The primary aim of this study was to measure serum IL-9 levels in patients with inflammatory bowel disease (IBD), and evaluate their relationships with the patients' clinical characteristics. The secondary aim was to determine the levels of interferon-γ (IFN (interferon)-γ), Th2 cytokines (IL-4, IL-5 and IL-13), and IL-6 in order to clarify the context of detectable peripheral cytokines in which IL-9 is produced.

Liver Regeneration Induced By Extracorporeal Portal Vein Arterialization in a Swine Model of Carbon Tetrachloride Intoxication.

Introduction: This study aimed to determine whether a controlled portal blood arterialization by a liver extracorporeal device (L.E.O2 NARDO) is effective in treating acute hepatic failure (AHF) induced in swine by carbon tetrachloride (CCl4) administration.

Performance capacity evaluated using the 6-minute walk test: 5-year results in patients with diffuse systemic sclerosis and initial interstitial lung disease.

Objectives: To identify factors indicating exercise-induced oxygen desaturation during the 6-minute walk test (6MWT) in patients with diffuse systemic sclerosis (SSc) and initial interstitial lung disease (ILD).

Methods: The study involved 121 consecutive adult anti-Scl 70 autoantibody-positive SSc patients with initial ILD, 93 of whom were followed up for five years. Before enrolment and then annually, the patients underwent high-resolution computed tomography (HRCT), functional lung tests, with carbon monoxide diffusion capacity of the lung (DLCO) and its components (alveolar-capillary membrane [Dm] and pulmonary blood volume [Vc]), the evaluation of dyspnea before and after the 6MWT using the Borg scale, and transthoracic echocardiography.

Paradoxical Expansion of Th1 and Th17 Lymphocytes in Rheumatoid Arthritis Following Infliximab Treatment: a Possible Explanation for a Lack of Clinical Response.

Purpose: The immunogenicity of anti-TNF-α drugs may affect their safety and efficacy. Infliximab (IFX), a chimeric monoclonal antibody, induces antibody formation in up to 60% of cases. Some studies have suggested the involvement of a Th1 response to TNFα blockers following immunization, but the triggering of Th17 responses has never been reported.

How to measure chronic pain: New concepts.

The assessment of chronic pain and its impact on physical, emotional and social functions requires the use of multidimensional qualitative and health-related quality of life instruments, but there is still little agreement concerning what these may be or which approach to adopt. Increasing focus on patient-reported outcomes in medicine has had the positive effect of giving prominence to the views and experiences of patients with chronic pain, and the ecological momentary assessment (EMA) approach allows patients' symptoms to be assessed in their natural environment in real time without the need for recall. Computerised EMA symptom diaries are now generally regarded as the 'gold standard' in the field of pain medicine, and they have recently attracted increasing attention as an essential component of health-care monitoring systems based on the information and communication technology.

Pain management in cryoglobulinaemic syndrome.

Cryoglobulinaemic syndrome (CS) includes clinical signs and symptoms that range from the classic triad of Meltzer and Franklin (purpura, weakness and arthralgias) to multiple organ involvement, and it may be characterised by nociceptive or neuropathic pain. Both types of pain use the same pathways and neurotransmitters, but nociceptive pain has an adaptive system and biological function whereas neuropathic pain does not. Managing CS means dealing with often very different clinical patterns, activity and severity with the aim of preventing irreversible organ damage, reducing pain, improving the patients' quality of life and reducing social costs.

The words of pain in complex regional pain syndrome.

Complex regional pain syndrome (CRPS) encompasses a wide range of painful conditions, but it is characterised by continuing (spontaneous and/or evoked) limb pain that is seemingly disproportionate in time or degree to the usual course of any known trauma or other lesion. The pain is regional, with distal predominance usually but not related to a specific nerve territory or dermatome, and it is usually associated with abnormal sensory, motor, sudomotor, vasomotor and/or trophic findings. The complexity of the aetiopathogenetic factors making up the clinical picture of CRPS is mirrored by the inconsistency of almost all of the monotherapies used to treat it so far.

Pain in systemic connective tissue diseases.

Pain is frequent in patients with connective tissue diseases (CTDs), particularly those affected by systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) in which it is virtually ubiquitous and can have different causes. The SLE classification criteria include pain associated with musculoskeletal involvement, which are frequently the initial symptom of SLE and can include arthralgia, arthritis and/or myalgia. Chronic widespread pain, the cornerstone of fibromyalgia (FM), is also frequently associated with CTDs.

Pain in systemic inflammatory rheumatic diseases.

The sometimes intense, persistent and disabling pain associated with rheumatoid arthritis (RA) and spondyloarthritis frequently has a multifactorial, simultaneously central and peripheral origin, and it may be due to currently active inflammation or joint damage and tissue destruction caused by a previous inflammatory condition. The symptoms of inflammatory pain symptoms can be partially relieved by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in central pain regulation mechanisms, as in the case of the chronic widespread pain (CWP) characterising fibromyalgia. The importance of distinguishing CWP from inflammatory pain is underlined by the fact that drugs such as tumour necrosis factor inhibitors are expensive, and direct costs are higher in patients with concomitant CWP than in those without.
