Review
Standardised interpretation of capillaroscopy in autoimmune idiopathic inflammatory myopathies: A structured review on behalf of the EULAR study group on microcirculation in Rheumatic Diseases.
OBJECTIVE
We conducted a systematic review, on behalf of the EULAR Study Group on Microcirculation in Rheumatic Diseases (EULAR SG MC/RD), to investigate the value of nailfold videocapillaroscopy (NVC) in idiopathic inflammatory myopathies (IIM).
METHODS
Three electronic databases were systematically searched to find all relevant manuscripts reporting NVC outcomes in IIM patients. Articles were assessed based on study design, population, NVC methodology and description of NVC results. To allow comparison between the articles, all NVC results were interpreted according to standardised capillaroscopic terminology, as previously consented by the EULAR SG MC/RD and the Scleroderma Clinical Trials Consortium (SCTC) Group on Capillaroscopy.
RESULTS
Of the 653 identified records; five were retained after critical appraisal on title, abstract and manuscript level. A marked difference in NVC was observed between (juvenile) dermatomyositis [(j)DM] versus polymyositis, healthy controls and systemic sclerosis patients. In addition, reduced capillary density and scleroderma pattern seem to be associated with active disease in (j)DM, while immunosuppressive treatment appears to reduce NVC abnormalities.
CONCLUSION
This is the first systematic review investigating NVC in IIM, interpreting the results according to an international consented standardised manner, as proposed by the EULAR SG MC/RD and SCTC Group on Capillaroscopy. We can conclude that NVC presents a promising asset in the diagnosis of (j)DM. Moreover, NVC could be a biomarker for organ involvement and follow-up. Large multicentre prospective standardised studies are further needed to definitely describe associations with clinical and laboratory parameters in the different IIM subtypes.

OBJECTIVES
Dermatomyositis (DM) and juvenile dermatomyositis (JDM) are idiopathic inflammatory myopathies, which can be resistant and unresponsive to initial treatments, leading to severe complications and impaired quality of life. There are few randomised trials in dermatomyositis and the outcomes reported may not be consistent, which can limit decision-making. The aim of this study is to assess the scope and consistency of outcomes reported in randomised trials in dermatomyositis.
METHODS
MEDLINE, Embase, PsycINFO and clinicaltrials.gov were searched from 1993-2020 for randomised trials in children and adults with dermatomyositis. The frequency and characteristics of the outcomes reported were analysed and classified.
RESULTS
20 trials were included. Across these trials, a total of 743 outcome measures were reported, which were grouped into 34 outcome domains; of which 17 were clinical, 13 were surrogate/biochemical, and 4 were patient-reported outcomes. The top five most frequently reported outcome domains were muscle inflammation (15 trials, 46 outcome measures), physical function (14 trials, 16 outcome measures), muscle strength (13 trials, 30 outcome measures), global health (12 trials, 33 outcome measures) and immunologic marker (11 trials, 91 outcomes).
CONCLUSIONS
The majority of outcomes reported in trials in people with dermatomyositis and JDM are clinical and surrogate outcomes rather than patient-reported outcomes. The outcomes reported are very inconsistent across trials, with wide heterogeneity in the measures used. Standardised reporting of critically important outcomes is needed to strengthen the value of trials for decision-making.

Meta-Analysis
OBJECTIVE
The effectiveness of rituximab in anti-melanoma differentiation-associated gene 5 (MDA5) dermatomyositis (DM) with interstitial lung disease (ILD) has been explored only in isolated case reports and small series. This paper aims to review the current evidence regarding rituximab (RTX) use in the treatment of ILD related to anti-MDA5 DM (anti-MDA5 DM-ILD).
METHODS
We conducted a review by searching PubMed, Web of Science, Embase, and Cochrane for articles with information on patients with anti-MDA5 DM and RTX treatment, published until August 2021, in English language. The selected studies listed variation in chest high-resolution computed tomography (HRCT) and/or pulmonary function test (PFT) as a primary outcome, in patients with anti-MDA5 DM-related ILD after using RTX.
RESULTS
Of the 145 potentially eligible articles, 17 were selected. The information gathered from a total of 35 patients with anti-MDA5 DM-ILD was reviewed, including 13 men and 22 women. Patient age at onset was 47.60 ± 13.72 years old. A total of 11.43% (4/35) of the patients were found to have chronic ILD (C-ILD) and 88.57% (31/30) exhibited rapidly progressive ILD (RP-ILD). Most patients (29/30) had typical DM rashes. Prior to RTX administration, the majority of patients (27/35) were treated with medium- or high-dose glucocorticoids and at least one additional immunotherapeutic agent. With regard to RTX efficacy for ILD in anti-MDA5 DM, 71.43% (25/35) of the patients responded to treatment. Skin rash also improved in more than half of the patients after RTX treatment. The most common side effects were infections, reported by 37.14% (13/35) of the patients after using RTX.
CONCLUSION
As a CD20 targeting drug, RTX is a promising therapeutic tool for anti-MDA5 DM-ILD, although the risk of infections should be considered before treatment. Further prospective controlled studies are required to evaluate the optimal RTX treatment regimen.

Review
UNLABELLED
The immunogenicity of vaccines in children with juvenile autoimmune rheumatic diseases (JARDs) can be reduced, there are additional safety concerns around vaccination, and there is a potential for worsening in disease activity. In this systematic review, we summarise studies that investigated the immunogenicity and safety of routine vaccines in children and adolescents with JARD on immunosuppressive treatment. We identified 37 studies investigating 2571 children and adolescents with JARD on immunosuppressive treatment and 4895 control children. Of the 56 geometric mean antibody titres measured, 19 (34%) were lower, six (11%) higher, and 31 (55%) similar; of the 39 seroprotection rates measured, 10 (26%) were lower, two (5%) higher, and 27 (69%) similar; and of the 27 seroconversion rates measured, nine (33%) were lower, two (8%) higher, and 16 (59%) similar in children with JARD on immunosuppressive treatment compared with control children. However, many of the studies were underpowered, and not designed to show non-inferiority between children with JARD and controls. Subgroup analysis for different types of immunosuppressive treatments was not feasible, as most studies did not report results by treatment. Severe adverse events were reported in 38 children (33 with juvenile idiopathic arthritis, four with systemic lupus erythematosus, and one in a healthy child); most of them were likely not related to the vaccination (e.g. elective hospitalisation or surgery). A worsening in disease activity was reported in 44 (2%) children with JARD; again, many of them were likely not related to the vaccination. There were no safety concerns with live attenuated vaccines; however, only few studies reported results for this.
CONCLUSION
Vaccination in children with JARD on immunosuppressive treatment is safe and should be promoted, especially since these children are at increased risk for infection. The importance for the completion of vaccination schedules should be stressed. Strategies to compensate for the lower vaccine responses, which are found in approximately one-third of these children, include measuring antibody levels to determine the optimal timing for the administration of additional booster doses.
WHAT IS KNOWN
• Children with juvenile autoimmune rheumatic diseases (JARDs) are at higher risk for infections, due to their underlying disease and their immunosuppressive treatment. • In children with JARD, the immunogenicity of vaccines might be reduced, and concerns about safety or the potential for worsening in disease activity after vaccination exist.
WHAT IS NEW
• Our systematic review shows that vaccines in children with JARDs on immunosuppressive treatment are safe and immunogenic. • There are several limitations of the currently published studies, including random timing of measuring vaccine responses and age differences between children with JARD and control groups. Many of the studies were underpowered, and not designed to show non-inferiority between children with JARD and controls.

OBJECTIVES
Juvenile idiopathic inflammatory myopathies (JIIMs) are a heterogeneous group of systemic autoimmune diseases. Juvenile dermatomyositis (JDM) is the predominant form of JIIMs, and is a rare, chronic autoimmune illness characterised by symmetric, proximal muscle damages and involvement of the skin. In the last two decades, the use of monoclonal antibodies has also been expanded to JIIMs; however, there is limited evidence on use of these treatments. We assessed the efficacy/effectiveness and safety of biologic agents in JIIMs.
METHODS
A systematic literature review was conducted using Embase®, MEDLINE®, MEDLINE®-In Process and Cochrane library to identify studies on biologics agents in JIIMs published in English language as full-text articles (1975 to December 2020) or conference abstracts (2000 to December 2020). Databases were searched with the key words regarding chronic myositis crossed with "biologic agents OR tocilizumab OR rituximab OR adalimumab OR infliximab OR anti-TNF OR etanercept". Of note, we did not include children, age, or age limits in the search as medical subject headings terms because we may have been able to extract a sub cohort of children from studies including both children and adults.
RESULTS
Of the 1633 retrieved publications, 18 articles were identified for a total of 165 patients. In real-world studies, definition of complete (CR) or partial response (PR) varied. JIIMs patients were most often treated with anti-TNF (88 pts); patients received etanercept (ETA), 48 patients infliximab (IFX), 4 patients received adalimumab (ADA). In other 15 patients IFX was followed by ADA. Rituximab (RTX) was used in 73 children. A single case series reported the use of abatacept (ABA) in 4 patients. Despite the reduced number of treated patients, complete response on myositis was reported in 29.6% (8/26) patients treated with at least one anti-TNF and in 38% (10/26) treated by RTX. Complete response of skin vasculitis has been reached in 33% (4/12) children on anti-TNF and in 36% on RTX (21/58). Anti-TNF agents might be efficient in treating calcinosis lesions.
CONCLUSIONS
Currently, the available evidence regarding the use of biologic treatment in JIIMs results quite limited but suggest a promising the use of anti-TNF agents and RTX in treating active JIIMs. Anti-TNF treatment might have a role in treating calcinosis. However, an overall very low quality of the available studies and multiple confounding factors hamper to suggest a treatment over another. Thus, randomised clinical trials are urgently required to attempt the optimal treatment in real-world setting.

Meta-Analysis
BACKGROUND
Gastric cancer is one of the most common cancers worldwide, with a high mortality rate. The potential etiological role of autoimmune (AI) disorders has been described in gastric cancer; however, the literature is controversial. This study aims to provide a comprehensive summary of the association between autoimmune disorders and the incidence of gastric cancer.
METHODS
This study was registered on PROSPERO under registration number CRD42021262875. The systematic literature search was conducted in four scientific databases up to May 17, 2021. Studies that reported standardized incidence rate (SIR) of gastric cancer in autoimmune disorders were eligible. We calculated pooled SIRs with 95% confidence intervals (CIs) in this meta-analysis.
RESULTS
We included 43 articles describing 36 AI disorders with data of 499,427 patients from four continents in our systematic review and meta-analysis. Significantly increased incidence of gastric cancer was observed in dermatomyositis (SIR = 3.71; CI: 2.04, 6.75), pernicious anemia (SIR = 3.28; CI: 2.71, 3.96), inflammatory myopathies (SIR = 2.68; CI:1.40; 5.12), systemic lupus erythematosus (SIR = 1.48; CI: 1.09, 2.01), diabetes mellitus type I (SIR = 1.29; CI:1.14, 1,47), and Graves' disease (SIR = 1.28; CI: 1.16, 1.41). No significant associations could be found regarding other AI disorders.
CONCLUSIONS
Pernicious anemia, Graves' disease, dermatomyositis, diabetes mellitus type I, inflammatory myopathies, and systemic lupus erythematosus are associated with higher incidence rates of gastric cancer. Therefore, close gastroenterological follow-up or routinely performed gastroscopy and application of other diagnostic measures may be cost-effective and clinically helpful for patients diagnosed with these autoimmune diseases.

Review
BACKGROUND
The common inflammatory scalp diseases, such as psoriasis, seborrheic dermatitis, lichen planopilaris, discoid lupus erythematosus, contact dermatitis, or pemphigus may share similar clinical features.
OBJECTIVE
To identify and systematically review the available evidence on the accuracy of trichoscopy in inflammatory scalp disorders.
METHODS
A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 58 articles were included in the analysis.
RESULTS
The following trichoscopy features were found to show the highest specificity for the respective diseases: in psoriasis: diffuse scaling, simple and twisted red loops, red dots and globules, and glomerular vessels; in seborrheic dermatitis: atypical vessels, thin arborizing vessels, and structureless red areas; in discoid lupus erythematosus: follicular plugs and erythema encircling follicles; in lichen planopilaris: milky red areas or fibrotic patches; in contact dermatitis: twisted red loops; in pemphigus foliaceus: white polygonal structures and serpentine vessels; in pemphigus vulgaris: red dots with whitish halo and lace-like vessels; and in dermatomyositis: lake-like vascular structures.
LIMITATIONS
Different nomenclature and variability in parameters, which were analyzed in different studies.
CONCLUSION
This systemic analysis indicates that trichoscopy may be used with high accuracy in the differential diagnosis of inflammatory scalp diseases.

BACKGROUND
Although fatigue is a prevalent distressing symptom in children and adolescents with Pediatric Rheumatic Conditions (PRCs), intervention studies designed for reducing fatigue in PRCs are limited.
AIM
To systematically review evidence regarding the efficacy of interventions intended to reduce fatigue in patients with PRCs.
METHODS
Comprehensive electronic searches were performed in PubMed/ MEDLINE, Embase, Web of Science and Cinahl. The risk of bias was assessed using the 'Revised Cochrane risk-of-bias tool for randomized trials' and 'Quality Assessment Tool for Before-After Studies With No Control Group' for respectively studies with and without a control group.
RESULTS
Ten out of 418 studies were included with a total of 240 participants (age range 5-23 years). Interventions included land-based and aquatic-based exercise therapy, prednisolone, vitamin-D and creatine supplementation, psychological therapy and a transition program into an adult rheumatology program. Fatigue was assessed with self-reported questionnaires in all included studies. Land-based exercise therapy was effective in one pre-post intervention study, whereas not effective in two randomized controlled trials. Aquatic-based exercise therapy was found more effective than land-based exercise therapy. Two placebo-controlled studies showed a significant positive effect in reducing subjective fatigue with prednisolone and vitamin-D. Creatine was not found effective. Cognitive therapy was effective in one pre-post intervention study, while one RCT did not show an effect in reducing fatigue. A transition program based on health education showed a small reducing effect, however, it was not clear if this was a significant effect. Six studies showed a high risk of bias, three studies a moderate risk, and one study had a low risk of bias.
CONCLUSIONS
Insufficient evidence is provided to substantiate the efficacy of current interventions to reduce fatigue in PRCs. The low number of studies, non-comparable interventions, risk of bias, and inconclusive outcomes of the included studies denote future research should focus on intervention studies aimed at the treatment of fatigue in children and adolescents with PRCs. Identification of possible underlying biological and psychosocial mechanisms as possible treatment targets to reduce complaints of fatigue in children and adolescents with PRCs is warranted.

Review
Childhood rheumatic diseases are a group of diseases that can affect many organs and systems, resulting in pain, joint stiffness, muscle atrophy and weakness. Physical inactivity has been reported in many childhood rheumatic diseases. There are many studies in the literature comparing the effectiveness of exercise programs in children with juvenile idiopathic arthritis. Exercise and physical activity are considered major parts of the treatment of children with rheumatic disease. The aim of this review is to systematically present studies on physical activity and exercise programs in children with rheumatism from the last 5 years. An internet-based search of three databases-PubMed, PEDro and Medline- was conducted to find relevant studies. Two reviewers individually identified studies on the basis of their title, abstract or full text-as necessary-to determine their eligibility. Differences of opinion between the two examiners were resolved by discussion. Scientific studies of children with different rheumatic diagnoses have shown that physical activity and exercise have a significant effect on reducing the symptoms of the disease. However, the duration, frequency, method and evaluation of the exercises are still being discussed in the literature.

Meta-Analysis
INTRODUCTION
Acute exacerbation (AE) is a devastating phenomenon and reported to be complicated with systemic autoimmune disease-associated interstitial lung disease (ILD). The aim of this study was to investigate the incidence and prognosis of AE of systemic autoimmune disease-ILD and clarify relevant clinical information predictive of these outcomes.
METHOD
This study was designed as a systematic review and meta-analysis. A primary study except for a case report, which reported the incidence and/or prognosis of AE of systemic autoimmune disease-ILD, was eligible for the review. Electronic databases such as Medline and EMBASE were searched from 2002 through 23 February 2020. Two reviewers independently selected eligible reports and extracted relevant data. Risk of bias of individual studies was assessed similarly. The incidence and prognosis of the disease were analysed qualitatively. Univariate results of risk and prognostic factors were combined if feasible.
RESULTS
Out of a total of 2662 records, 24 studies were eligible. A total of 420 subjects with 45.7% of men developed AE of systemic autoimmune disease-ILD and the two major underlying systemic autoimmune diseases were rheumatoid arthritis (34.2%) and polymyositis/dermatomyositis (31.9%). The frequency ranged from 4.3 to 32.9% with the incident rate being 3.19 and 5.77 per 100 patient-years and all-cause mortality was between 30.0 and 58.3% at 90 days. Age at initial presentation was significantly associated with the development of AE of systemic autoimmune disease-ILD with an HR of 1.22 (95%CI 1.05-1.50) while a percentage of predicted diffusing capacity of the lung for carbon monoxide (%DLCO) was also significantly associated with the development of the disease with an HR of 0.95 (95%CI 0.90-1.00) and an OR of 0.97 (95%CI 0.95-0.99). Partial pressure of arterial oxygen/fraction of inspired oxygen ratio (PaO/FiO) at AE was significantly associated with all-cause mortality of AE of systemic autoimmune disease-ILD with an HR of 0.99 (95%CI 0.98-0.99).
CONCLUSION
AE of systemic autoimmune disease-ILD was not uncommon and demonstrated dismal prognosis. Age at initial presentation and %DLCO were deemed as risk factors while PaO/FiO at AE was considered as a prognostic factor of the disease. Registration CRD42019138941.
