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.

Review
BACKGROUND
The idiopathic inflammatory myopathies (IIM) are a collection of autoimmune diseases that have a substantial impact on the entire body and include conditions such as dermatomyositis (DM), polymyositis (PM), sporadic inclusion body myositis, and immune-mediated necrotizing myopathy. These disorders are characterized by symptoms such as muscular weakness, pain, and dermal rash. This systematic review is intended to explore the potential link between bladder cancer and DM/PM.
METHODS
We performed a comprehensive systematic search on PubMed and Scopus until August 2022 to identify relevant research studies. The studies that met our inclusion criteria focused on patients with urinary bladder cancer and dermatomyositis, and/or polymyositis.
RESULTS
The patients' median age was 65.5 years (47-79), with the majority being male (15, 39.47%). Bladder cancer manifested before PM/DM in 5 (13.15%) patients, while in the majority of cases occurred after the cancer diagnosis. The stage of cancer at the time of the initial PM/DM diagnosis were mostly locally (11/20, 50%).During the first presentation, the patients had a median creatine kinase level of 2227 U/L, ranging between 44 and 10471. In one case, anti-TIF-1γ antibodies were found to be present. Among the cases with reported medical history (20/38), treatment immediately improved DM symptoms in 16 patients(53.8%) and in 3 patients(15%), symptoms of DM resurfaced during the period after the operation. Death was reported in 14 (36.8%) patients.
CONCLUSION
In conclusion, our study provides knowledge and understanding for identifying specific risk factors in patients with the coexistence of bladder cancer and DM/PM and their management. During the initial and follow-up screening, age, gender, and the clinicopathological subgroup of myositis should be considered to ensure proper management of the condition.

Review
Dermatomyositis is a rare, type I interferon-driven autoimmune disease, which can affect muscle, skin and internal organs (especially the pulmonary system). In 2021, we have noted an increase in new-onset dermatomyositis compared to the years before the SARS-CoV-2 pandemic in our center. We present four cases of new-onset NXP2 and/or MDA5 positive dermatomyositis shortly after SARS-CoV-2 infection or vaccination. Three cases occurred within days after vaccination with Comirnaty and one case after SARS-CoV-2 infection. All patients required intensive immunosuppressive treatment. MDA5 antibodies could be detected in three patients and NXP2 antibodies were found in two patients (one patient was positive for both antibodies). In this case-based systematic review, we further analyze and discuss the literature on SARS-CoV-2 and associated dermatomyositis. In the literature, sixteen reports (with a total of seventeen patients) of new-onset dermatomyositis in association with a SARS-CoV-2 infection or vaccination were identified. Ten cases occurred after infection and seven after vaccination. All vaccination-associated cases were seen in mRNA vaccines. The reported antibodies included for instance MDA5, NXP2, Mi-2 and TIF1γ. The reviewed literature and our cases suggest that SARS-CoV-2 infection and vaccination may be considered as a potential trigger of interferon-pathway. Consequently, this might serve as a stimulus for the production of dermatomyositis-specific autoantibodies like MDA5 and NXP2 which are closely related to viral defense or viral RNA interaction supporting the concept of infection and vaccination associated dermatomyositis.

OBJECTIVES
To perform a systematic literature review (SLR) on the association of common variable immunodeficiency (CVID) and rare and complex connective tissue and musculoskeletal diseases, namely systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), idiopathic inflammatory myopathies (IIM), systemic sclerosis (SSc), relapsing polychondritis, antiphospholipid syndrome, immunoglobulin (Ig) G4-related disease, as well as undifferentiated and mixed connective tissue disease.
METHODS
An SLR on studies and cases about the association of CVID and rare and complex connective tissue and musculoskeletal diseases was performed. Animal studies were excluded.
RESULTS
170 publications fulfilled the inclusion criteria. Sjögren's syndrome was the most frequent connective tissue disease in CVID-patients. Most case reports exist on SLE and CVID with SLE mostly preceding the manifestation of CVID. Multiple cases were published reporting the concurrence of CVID and inclusion body myositis and single cases were found on CVID and antisynthetase syndrome, polymyositis, limited SSc and relapsing polychondritis, respectively. There are no cases of CVID and antiphospholipid syndrome, IgG4-related disease, as well as undifferentiated and mixed connective tissue disease.
CONCLUSIONS
The concurrence of CVID and complex connective tissue and musculoskeletal diseases, especially SS, IIM, SSc and relapsing polychondritis is rare but relevant. The measurements of Ig-levels should be performed before the initiation of immunosuppressive therapy to allow for the differentiation of primary and secondary Ig-deficiency and substitute IG if necessary.

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.

Frontiers in Immunology 2024We performed a single-arm meta-analysis to evaluate the efficacy and safety of JAK inhibitors in the treatment of dermatomyositis (DM)/ polymyositis (PM). (Meta-Analysis)
Meta-Analysis
INTRODUCTION
We performed a single-arm meta-analysis to evaluate the efficacy and safety of JAK inhibitors in the treatment of dermatomyositis (DM)/ polymyositis (PM).
METHODS
Relevant studies from four databases were systematically searched until April 25, 2023. The primary endpoint was Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) and other outcomes were Manual Muscle Testing (MMT) and Creatine Kinase (CK). According to the type of JAK and medication regimen, we conducted subgroup analyses. The registration number in PROSPERO was CRD42023416493.
RESULTS
According to the selection criteria, we identified 7 publications with a total of 91 patients. Regarding skin lesions, the CDASI decreased by 17.67 (95% CI: -20.94 ~ -14.41). The CK increased by 8.64 U (95% CI: -28.25 ~ 45.53). About muscle lesions, MMT increased by 10.31 (95% CI: -2.83 ~ 23.46). Subgroup analysis revealed that different types of JAK inhibitors had various degrees of reduction. CDASI in patients treated with RUX had the lowest one [-20.00 (95% CI: -34.9 ~ -5.1)], followed by TOF [-18.29 (95% CI: -21.8 ~ -14.78)] and BAR [-11.2 (95% CI: -21.51 ~ -0.89)]. Additionally, the mean reduction in CDASI in patients treated with TOF alone was 16.16 (95% CI: -21.21 ~ -11.11), in combination with other immunosuppressants was 18.59 (95% CI: -22.74 ~ -14.45). For safety evaluation, one patient developed Orolabial HSV, and two patients developed thromboembolism events.
DISCUSSION
In summary, this meta-analysis demonstrated that JAK inhibitors can potentially treat DM/PM without severe adverse reactions.

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
Drug-induced dermatomyositis (DIDM) is a rare and underestimated variant of dermatomyositis (DM) characterized by muscle damage and skin rash and related to certain drug exposure. The spectrum of drugs causing DIDM has evolved over time, originally implicating hydroxyurea, penicillamine, and statins as causative agents. Tumor necrosis factor α inhibitors and immune checkpoint inhibitors have also been associated with such conditions. To bridge the gap between current literature and clinical practice, and therefore guide clinicians, we conducted a comprehensive review of English literature from Pubmed, EMBASE, and MEDLINE. Our analysis included demographic data, clinical features, laboratory findings, therapeutic outcomes, and extant research pertaining to the probable pathogenesis of DIDM induced by various drugs. Furthermore, we categorized the drugs involved in DIDM cases into biologics and traditional agents for subsequent statistical analysis. Over time, there has been a gradual accumulation of reported DIDM cases. A total of 69 published DIDM cases were documented in our study, among which 33 should be attributed to biologics and the remaining 36 to traditional drugs. Interestingly, 41 of all DIDM cases had a previous history of malignancies. Additionally, DIDM cases exhibited similar cutaneous and muscular manifestations to classic DM, with the exception of cases induced by hydroxyurea, which did not entail muscle damage. Positive antinuclear antibodies and anti-TIF1-γ autoantibodies have been predominantly observed in biologics-induced cases, while positive anti-TIF1-γ antibodies were merely reported in the cases that were primarily diagnosed with malignant diseases and exposed to ICIs afterwards. Anti-TIF1-γ antibodies may potentially serve as a red flag in the identification of co-existing malignant diseases in DM patients. We also provided a comprehensive summary and exploration of potential mechanisms lying behind drug-induced dermatomyositis. In conclusion, our review consolidates the current literature on DIDM, highlighting the evolving spectrum of medications and elucidating the differences in clinical manifestations, laboratory findings, and underlying mechanisms.

RATIONALE
Chronic graft versus host disease (cGVHD) is a systemic immune-mediated complication that occurs in approximately half of patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HCT), and remains the leading cause of late morbidity and mortality. cGVHD involves a heterogeneous group of organic manifestations, many of which mimic autoimmune diseases such as scleroderma, primary biliary cholangitis, Sjögren syndrome and polymyositis.
PATIENT CONCERNS
A 60-years-old female with a history of allo-HCT developed de novo cGVHD 11 months after allo-HCT with isolated liver involvement. The patient presented with jaundice, cytolysis, cholestasis and concomitant acute digital ischemia. Liver biopsy and autoimmunity tests were performed and were found to be compatible with immune-mediated liver damage. Nailfold capillaroscopy revealed microangiopathy, characterized by avascular areas and some enlarged capillaries resembled an early systemic sclerosis pattern.
DIAGNOSIS
Biliary cholangitis-like and digital ischemia related to cGVHD.
INTERVENTIONS
The patient was treated with high-dose prednisone and ursodeoxycholic acid, and extracorporeal photopheresis. The patient required hospital admission for administration of intravenous prostacyclin due to refractory Raynaud syndrome.
OUTCOMES
After 6 to 8 weeks, the patient achieved a good response, with evident clinical improvement and progressive normalization of liver function.
LESSONS
cGVHD is a multiorgan pathological condition, and this case emphasizes that a multidisciplinary team, including rheumatologists, should be involved in the follow-up of allo-transplant patients to ensure that the clinical complications are adequately addressed. Early intervention is critical for improving patient' prognosis.In addition, we performed a systemic literature review based on published case articles on hepatic cGVHD and digital ischemia published up to August 2022. To the best of our knowledge, this is the first reported case of such an association.

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.
