Abstract Objectives Pneumocystis jirovecii pneumonia (PJP) is associated with significant morbidity and mortality in adult myositis patients; however, there are few studies examining PJP in juvenile myositis [juvenile idiopathic inflammatory myopathy (JIIM)]. The purpose of this study was to determine the risk factors and clinical phenotypes associated with PJP in JIIM. Methods An research electronic data capture (REDCap) questionnaire regarding myositis features, disease course, medications and PJP infection characteristics was completed by treating physicians for 13 JIIM patients who developed PJP (PJP+) from the USA and Canada. Myositis features and medications were compared with 147 JIIM patients without PJP (PJP–) from similar geographic regions who enrolled in National Institutes of Health natural history studies. Results PJP+ patients were more often of Asian ancestry than PJP– patients [odds ratio (OR) 8.7; 95% CI 1.3, 57.9]. Anti- melanoma differentiation associated protein 5 (MDA5) autoantibodies (OR 12.5; 95% CI 3.0, 52.4), digital infarcts (OR 43.8; 95% CI 4.2, 460.2), skin ulcerations (OR 12.0; 95% CI 3.5, 41.2) and interstitial lung disease (OR 10.6; 95% CI 2.1, 53.9) were more frequent in PJP+ patients. Before PJP diagnosis, patients more frequently received pulse steroids, rituximab and more immunosuppressive therapy compared with PJP– patients. Seven PJP+ patients were admitted to the intensive care unit and four patients died due to PJP or its complications. Conclusions PJP is a severe infection in JIIM that can be associated with mortality. Having PJP was associated with more immunosuppressive therapy, anti-MDA5 autoantibodies, Asian race and certain clinical features, including digital infarcts, cutaneous ulcerations and interstitial lung disease. Prophylaxis for PJP should be considered in juvenile myositis patients with these features.

Interstitial lung disease (ILD) is a common and severe complication of idiopathic inflammatory myopathies (IIM). The aim of our study was to identify risk factors for ILD by evaluating both clinical and biochemical features in IIM patients with or without ILD. From January 2008 to December 2011, medical records of 134 IIM patients in our rheumatology unit were reviewed. The patients were divided into ILD group (83 patients) and non-ILD group (51 patients). The clinical features and laboratory findings were compared. The univariable analyses indicated that arthritis/arthralgia (54.2% versus 17.6%,P<0.05), Mechanic’s hand (16.9% versus 2.0%,P<0.05), Raynaud’s phenomenon (36.1% versus 2.0%,P<0.05), heliotrope rash (44.6% versus 19.6%,P<0.05), fever (43.4% versus 21.6%,P<0.05), elevated ESR (60.2% versus 35.3%,P<0.05), elevated CRP (55.4% versus 31.4%,P<0.05), or anti-Jo-1 antibody (20.5% versus 5.9%,P<0.05) were risk factors for developing ILD in IIM. Multivariable unconditional logistic regression analysis that showed arthritis/arthralgia (OR 7.1, 95% CI 2.8–18.1), Raynaud’s phenomenon (OR 29.1, 95% CI 3.6–233.7), and amyopathic dermatomyositis (ADM) (OR 20.2, 95% CI 2.4–171.2) were the independent risk factors for developing ILD in IIM.

Background. The risk factors for the mortality rate of Pneumocystis jirovecii pneumonia (PCP) who required mechanical ventilation (MV) remained unknown. Methods. A retrospective chart review was performed of all PCP patients admitted to our intensive care unit and treated for acute hypoxemic respiratory failure to assess the risk factors for the high mortality. Results. Twenty patients without human immunodeficiency virus infection required mechanical ventilation; 19 received noninvasive ventilation; and 11 were intubated. PEEP was incrementally increased and titrated to maintain FIO2 as low as possible. No mandatory ventilation was used. Sixteen patients (80%) survived. Pneumothorax developed in one patient with rheumatoid arthritis (RA). Median PEEP level in the first 5 days was 10.0 cmH2O and not associated with death. Multivariate analysis showed the association of incidence of interstitial lung disease and increase in serum KL-6 with 90-day mortality. Conclusions. We found MV strategies to prevent pneumothorax including liberal use of noninvasive ventilation, and PEEP titration and disuse of mandatory ventilation may improve mortality in this setting. Underlying disease of interstitial lung disease was a risk factor and KL-6 may be a useful predictor associated with mortality in patients with RA. These findings will need to be validated in larger studies.

Abstract Background: Interstitial lung disease (ILD) and its rapid progression (RP) were main contributors to unfavorable outcome of idiopathic inflammatory myopathy (IIM) patients. This study aimed at identifying the clinical value of PET/CT scan in IIM-ILD patients as well as constructing a predicting model for RP-ILD.Methods: Adult IIM-ILD patients who were hospitalized at four divisions of the First Affiliated Hospital, Zhejiang University School of Medicine (FAHZJU) from Jannuary 1st 2017 to December 31st 2020 were reviewed. PET/CT scan as well as other factors of patients who met the inclusion and exclusion criteria were collected and analyzed.Results: A total of 61 IIM-ILD patients were finally enrolled into this study. Twenty-one patients (34.4%) developed RP-ILD and 24 patients (39.3%) died in follow-up. After false discovery rate (FDR) correction, percent-predicted diffusing capacity of the lung for carbon monoxide (DLCO%, P=0.014), bilateral lung mean standard uptake value (SUVmean, P=0.014) and abnormal mediastinal lymph node (P=0.045) were significantly different in comparison between RP-ILD and non-RP-ILD groups. A “DLM” model was hereby established by including the above three values to predict RP-ILD with a cutoff value of ≥2 and an area under the curve (AUC) of 0.905. Higher bilateral lung SUVmean (P=0.019) and spleen SUVmean (P=0.011) were observed in IIM-ILD patients who died within three months, and a moderate correlation was recognized between the two values. Conclusions: Elevated bilateral lung SUVmean and abnormal mediastinal lymph node were associated with RP-ILD in IIM-ILD patients. The “DLM” model was valuable in predicting RP-ILD and demanded further evaluation.

Abstract Objectives Few studies have investigated the prognostic factors for idiopathic inflammatory myopathy-associated interstitial lung disease (IIM-ILD) across different clinical/serological phenotypes. Methods We conducted a retrospective analysis of patients diagnosed with IIM between January 2012 and December 2017. Results Of the 760 IIM cases registered, 679 adult cases were included in this study. ILD was present in 508 cases, and the presence of ILD in the clinically amyopathic DM, DM and PM groups was 92.7, 73.6 and 55.1%, respectively (P &lt; 0.01). The prevalence of ILD in the anti-synthetase antibody (ASA)+-IIM group was higher than that in ASA–-IIM group (95.2 vs 72.4%, P &lt; 0.01); no such difference was found between the anti-histidyl-tRNA synthetase (Jo-1)+-IIM and Jo-1–ASA+-IIM groups (93.0 vs 98.5%, P &gt; 0.05). The prevalence of ILD in the melanoma differentiation-associated protein-5 (MDA-5)+-IIM group was higher than that in MDA-5–-IIM group (97.8 vs 72.1%, P &lt; 0.01). Among adults with IIM, men with concurrent ILD, who were older than 50 years, were most likely to die. No significant difference was found in the all-cause mortality rates between DM-ILD and clinically amyopathic DM-ILD groups (33.3 vs 23%, P &gt; 0.05), although both were higher than that in PM group (13.2%, P = 0.01 and P &lt; 0.05, respectively). No difference was found in the all-cause mortality rates between MDA5–ASA–-IM-ILD and MDA5–ASA+-IM-ILD groups (17.2 vs 12.8%, P &gt; 0.05), and both were lower than that in MDA5+ASA–-IM-ILD group (33.7%, P &lt; 0.05). Conclusion The prevalence of ILD in IIM and the prognosis of IIM-ILD patients may vary depending on the statuses of the ASA and MDA-5 antibodies.

Abstract Objectives JDM and juvenile overlap myositis represent heterogeneous subtypes of juvenile idiopathic inflammatory myopathy (JIIM). Chronic evolution can occur in up to 60% of cases, and morbidity/mortality is substantial. We aimed to describe the clinical, biological, histological and type I IFN status in JIIM associated with anti-melanoma differentiation-associated protein 5 (anti-MDA5) autoantibodies at presentation (group 1) in comparison with other JIIM (group 2). Methods This was a retrospective and prospective study of patients with JIIM ascertained from three French paediatric rheumatology reference centres between 2013 and 2019. Muscle biopsies were reviewed. Type I interferon pathway activity was assessed by dosage of IFNα serum protein and the expression of IFN-stimulated genes. Results Sixty-four patients were included, 13 in group 1 (54% JDM and 46% juvenile overlap myositis) and 51 in group 2 (76% JDM and 24% juvenile overlap myositis). Group 1 patients demonstrated more arthritis, skin ulcerations, lupus features and interstitial lung disease, and a milder muscular involvement. Serum IFNα levels were higher in group 1 than 2, and decreased after treatment or improvement in both groups. Outcome was similar in both groups. Unconventional treatment (more than two lines) was required in order to achieve remission, especially when skin ulceration was reported. Conclusion This study indicates a higher frequency of arthritis, skin ulcerations and interstitial lung disease, but milder muscular involvement, in JIIM with positive anti-MDA5 autoantibodies compared with other JIIM. Our data support an important role of systemic IFNα in disease pathology, particularly in the anti-MDA5 auto-antibody-positive subgroup. In severe and refractory forms of JIIM, IFNα may represent a therapeutic target.

Multicenter Randomized Controlled Trial

In patients with idiopathic inflammatory myopathy, the presence of the melanoma differentiation-associated gene 5 (MDA5) antibody carries an extremely poor prognosis as a result of the associated interstitial lung disease (ILD) that is often rapidly progressive and refractory to therapies. Management of anti-MDA5 associated ILD is a challenging task as there is a paucity of clinical data and treatment guidelines in the literature. We hereby describe a proposed protocol for a multicenter randomized controlled trial to compare the efficacy of intravenous cyclophosphamide and obinutuzumab in combination with high-dose glucocorticoids and tacrolimus in terms of mortality at six months (primary outcome). The epidemiology, pathogenesis and treatment options of anti-MDA5 associated ILD are briefly reviewed.
