In the management of rheumatic musculoskeletal disorders (RMDs), regular physical activity (PA) is an important recognized non-pharmacological intervention. This systematic review and meta-analysis aims to evaluate how the use of wearable devices (WDs) impacts physical activity in patients with noninflammatory and inflammatory rheumatic diseases.

Chronic nonbacterial osteomyelitis (CNO) is a rare inflammatory bone disease. The distinct CNO subtype that affects the anterior chest wall is descriptively named sternocostoclavicular hyperostosis (SCCH) and mainly occurs in adults. Literature on CNO/SCCH is scattered and lacks diagnostic and therapeutic consensus.

In women with systemic autoimmune rheumatic diseases (SARDs), female sexual dysfunction (SD) remains underestimated. We aimed to explore the prevalence and correlates of SD in females with SARDs.

An increased risk of adverse maternal and foetal pregnancy complications (including pre-eclampsia, intrauterine growth restriction, and small for gestational age) is well described in women with autoimmune rheumatic disease (ARD) compared with the general population (GenPop). It is less clear, however, whether this risk of adverse pregnancy outcome (APO) also exists in women with 'preclinical ARD' (pre-ARD) before they are diagnosed with an ARD many years post-partum. Therefore, we have undertaken a systematic review of the available evidence on APO in patients who subsequently were diagnosed with a rheumatic disease to identify whether there is an increased risk in pre-ARD.

A decline in the frequency of AA amyloidosis secondary to RA and infectious diseases has been reported. We aimed to determine the change in the frequency of AA amyloidosis in our Behçet's syndrome (BS) patients and to summarize the clinical characteristics of and outcomes for our patients, and also those identified by a systematic review.

Statins are a class of lipid-lowering medications used worldwide by millions of people and are safe for frequent use in most patients. However, they cause necrotizing autoimmune myopathy in some patients. We reviewed case reports of 80 patients from 2010 to present diagnosed with statin-induced necrotizing autoimmune myopathy (SINAM), aiming to analyze the clinical, physiological, serologic characteristics and outcomes of SINAM. The mean age of these patients was 66 ±9.4, the majority being male (61.3%). All patients reported proximal muscle weakness, and a few had myalgias, extra muscular symptoms such as dysphagia, and pulmonary complications. Most of the patients were on atorvastatin, simvastatin, or rosuvastatin. The mean creatine kinase was 10,094.2 ±7,351.7 U/l, and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase enzyme was positive for 93.8% of patients. The majority of patients were started on steroids; other treatments were also used. Prompt cessation of statins and initiation of immunosuppressants reduced morbidity and mortality.

Small ubiquitin-like modifier (SUMO) proteins can reversibly attach covalently or non-covalently to lysine residues of various substrates. The processes are named SUMOylation and de-SUMOylation, which maintain a dynamic balance in the physiological state, and are regulated by SUMO components. However, the dysregulation of components disturbs the balance and alters the functions of target proteins, which causes the occurrence of diseases. To date, certain SUMO components, including SUMO-1, SUMO-2/3, SAE1/Uba2, Ubc9, PIASs (protein inhibitors of activated signal transducer and activator of transcription) and SENPs (SUMO-specific proteases), have been found to participate in the pathogenesis of RA and their potential value as therapeutic targets also have been highlighted. In addition, single nucleotide polymorphisms (SNPs) in the SUMO components have been reported to be associated with disease susceptibility. Until now, only the SNP site of SUMO-4 has been reported in RA. Here we provided a systematic overview of the general characteristics of SUMO components and highlighted a summary of their impact on RA.

Pain is the major complication of osteoarthritis (OA) patients and is a decisive symptom for medical intervention. Gamma-aminobutyric acid (GABA) derivatives are optional painkillers but not widely used in pain management of OA patients. We synthesized the efficacy and safety of GABA derivatives for OA pain management.

We aimed to systematically review the literature to retrieve evidence on the diagnostic and prognostic value of musculoskeletal ultrasound for a treat to target (T2T) approach in RA.

To systematically review the psychometric properties of outcome measurement instruments used in ANCA-associated vasculitis (AAV).

The use of systemic glucocorticoids (SGCs) is traditionally discouraged in the treatment of PsA and psoriasis due to the risk of psoriatic flares. However, despite this recommendation, SGCs are frequently prescribed for these patients. In this study we reappraise the old paradigm that SGCs are contra-indicated in the treatment of PsA and psoriasis.

Cryopyrin-associated periodic syndrome (CAPS) is a rare but treatable inherited autoinflammatory condition including familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and chronic infantile neurologic cutaneous articular syndrome (CINCA). Our objective was to describe the main features of CAPS AA amyloidosis (AA-CAPS) associated and the efficacy of IL-1 inhibitors in this indication.

Transplacental passage of certain biologic and targeted synthetic DMARDs leads to detectable levels in the neonate, which may impact on the safety of live vaccines. Guidelines advise delaying live vaccine administration in biologic-exposed infants until they are 7 months old.

To examine how residents are trained and assessed in musculoskeletal US (MSUS), MSUS-guided and landmark-guided joint aspiration and injection. Additionally, to present the available assessment tools and examine their supporting validity evidence.

Several pharmacological treatments have been proposed for the treatment of complex regional pain syndrome type-I (CRPS-I) in adults, but data regarding the efficacy of various agents for this disease is scarce. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to analyse the efficacy of the various pharmacological approaches in adults with CRPS-I.

Infections including tuberculosis (TB) are a leading cause of morbidity and mortality in idiopathic inflammatory myopathies (IIM). We systematically reviewed the prevalence of mycobacterial infections in patients with IIM.

Consensus-based recommendations guide standards of care for clinical practice. Pharmaceutical industry involvement in producing such recommendations might undermine their objectivity. We did a systematic review of rheumatology consensus-based recommendations that were published in English from 2000 to 2020. We compared those that were endorsed by major professional societies to those that were sponsored by industry using the validated Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Of 234 consensus-based recommendation projects, 51 (22%) were endorsed by major societies and 74 (32%) were sponsored by the pharmaceutical industry. Among industry-sponsored projects, the sponsor was involved in the consensus-based process in 21 (28%), provided a medical writer in 12 (16%), offered honoraria for participation in five (7%), and was allowed to approve the final draft of one project. When compared with projects endorsed by major societies, industry-sponsored projects were less likely to have a high quality assessment on the AGREE II instrument. These results suggest that industry sponsorship of consensus-based recommendations is common in projects that do not receive endorsement by major societies. Such projects are often of lower quality than guidelines endorsed by major professional societies. Medical journals should consider steps to encourage greater rigour of development and to limit undue influence by industry sponsors.

To evaluate flare risk when tapering or withdrawing biologic or targeted synthetic DMARDs (bDMARDs or tsDMARDs) compared with continuation in patients with inflammatory arthritis in sustained remission or with low disease activity.

Systemic sclerosis (SSc) is characterized by vasculopathy, fibrosis of skin and internal organs, and autoimmunity with complications including interstitial lung disease, pulmonary hypertension, and digital ulcers with substantial morbidity and disability. Patients with SSc may require considerable healthcare resources with economic impact. The purpose of this systematic review was to provide a narrative synthesis of the economic impact and healthcare resource utilization associated with SSc.
