Myxovirus resistance protein A (MxA) expression in myositides: Sarcoplasmic expression is common in both dermatomyositis and lupus myositis.

INTRODUCTION/AIMS: Myxovirus resistance protein A (MxA) is a type I interferon (IFN1) pathway activation marker and MxA sarcoplasmic expression is currently recognized as a highly specific marker for dermatomyositis (DM). However, we have frequently observed endothelial tubuloreticular inclusions (TRI), another surrogate IFN1 activation marker, in a variety of overlap myositides. The aim of this study was to examine MxA expression in those myositides. METHODS: We retrospectively performed MxA immunostaining on a wide range of myositides. RESULTS: MxA sarcoplasmic expression was present in DM (94.4%, 17/18), active lupus myositis (LM, 80%,16/20), inactive LM (36%, 4/11), antisynthetase syndrome (ASyS, 20%, 2/10), systemic sclerosis (13%, 2/15), Sjogren's syndrome (7.7%, 1/13), and human immunodeficiency virus (HIV) myositis (5.6%, 1/18) and was absent in immune-mediated necrotizing myopathy (IMNM, 0/16) and hydroxychloroquine myopathy (0/5). The sensitivity and specificity of MxA sarcoplasmic expression for LM and DM combined compared with all other myositides were 84.6% (95% CI: 69.5-94.1) and 92.1 (95% CI: 83.6-97.0), respectively, and superior to TRIs. MxA capillary expression was nonspecific. Histologically, 35% of LM cases demonstrated a unique panfascicular necrotizing myopathy pattern. The remainder of the LM cases had significant morphological overlap with DM/ASyS (20%), IMNM (20%), or polymyositis (15%). DISCUSSION: MxA sarcoplasmic expression is highly prevalent in LM and DM and is a useful marker in differentiating DM and LM from other myositides. LM can manifest in various pathology patterns that need to be differentiated from DM, IMNM, ASyS, and polymyositis.

Patient-Reported Outcomes Among Transition-Age Young Adults With Juvenile Idiopathic Arthritis in the Childhood Arthritis and Rheumatology Research Alliance Registry.

OBJECTIVE: To evaluate patient-reported care utilization and outcomes among young adults with juvenile idiopathic arthritis (JIA), including factors associated with complete transfer to adult rheumatology. METHODS: We included young adults with JIA enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from 2015 to 2019 with age ≥ 18 years at their last clinical site visit. We used data from the CARRA Registry Long-term Follow-up program, which follows inactive CARRA Registry patients and collects patient-reported information through phone surveys. We compared the characteristics of respondents with complete and incomplete transfer to adult rheumatology care at their first Long-term Follow-up phone survey. RESULTS: We identified 540 young adults with JIA; 187 (35%) responded to the Long-term Follow-up phone survey. The 54% of respondents with complete transfer to adult rheumatology were slightly older and reported more self-assessed disease activity, morning stiffness, and pain compared to those with incomplete transfer. Biologic use was high at both timepoints and did not differ by transfer status. Patients who completed the transfer were more likely to have private insurance and be actively pursuing postsecondary education compared to those with an incomplete transfer. Across the cohort, 65% reported problems with pain or discomfort and 45% with anxiety or depression. CONCLUSION: Young adult respondents with JIA in the CARRA Registry commonly report persistent medication use, but still report more problems with pain as compared to population norms. Additional work is needed to understand how best to address comorbid pain around the period of transition to adult care.

"You Just Have to Keep Going, You Can't Give Up": Coping mechanisms among young adults with lupus transferring to adult care.

INTRODUCTION: Coping mechanisms and emotional regulation are important contributors to psychosocial health during stressful life events. We sought to describe the coping and emotional responses of persons with childhood-onset systemic lupus erythematosus during the transfer from pediatric to adult healthcare. METHODS: Semi-structured in-depth one-on-one interviews were conducted with 13 young women aged 18-24 of minority background who had transferred to adult care in a public hospital system. Thematic analysis was used to identify themes motifs from the data. RESULTS: Participants described the use of (1) problem-focused coping such as the use of clear communication and self-education, (2) adaptive emotion-focused coping such as cognitive reframing and acceptance, (3) social coping including support-seeking, (4) meaning-making coping including positive religious framing and viewing events as learning opportunities for growth, and (5) disengaged coping including denial and social isolation. A range of emotional responses associated with the transfer were described including fear, anger, loss, and feelings of empowerment and excitement. CONCLUSION: Effective coping and emotional regulation are modifiable factors that may impact transfer-related outcomes and psychosocial health. Addressing coping mechanisms is relevant to the optimized transfer to adult care.

Inflammatory myositis in systemic lupus erythematosus.

BACKGROUND: The coexistence of inflammatory myositis in systemic lupus erythematosus (SLE) has not been extensively studied. In this study, we describe the incidence, distinct types of inflammatory myositis, and risk factors for this finding in a cohort of pediatric and adult SLE patients. METHODS: We identified SLE patients with coexisting myositis followed between 2010 and 2019 at two pediatric hospitals and one adult hospital. Demographic, clinical, laboratory, and pathological features of myositis were collected, and descriptive statistics were applied. RESULTS: A total of 1718 individuals were identified as having SLE (451 pediatric and 1267 adult patients). Of these, 108 were also diagnosed with inflammatory myositis (6.3%). People of black race had a significantly higher prevalence of inflammatory myositis, as did those with childhood-onset SLE compared to adult-onset disease. In the majority of patients (68%), SLE and inflammatory myositis presented concurrently. Overlapping features of systemic sclerosis occurred in 48%, while dermatomyositis-specific rashes were present in a third. Arthralgias and inflammatory arthritis were seen in >90%. Thrombotic events and significant pregnancy-related morbidity were present in more than a third of patients. Lymphopenia, hypocomplementemia, and a positive RNP were the most common laboratory features noted. Myositis-specific antibodies (MSA) and myositis-associated antibodies (MAA) were present in >40% of patients. A review of 28 muscle biopsy reports revealed a wide array of pathological features, including nonspecific changes, dermatomyositis, polymyositis, and necrotizing auto-immune myopathy. CONCLUSION: In our SLE patient population, 6.3% presented with concurrent inflammatory myositis. Dermatomyositis-specific rashes, clinical features of systemic sclerosis, arthralgias and arthritis, and cytopenias were common coexisting clinical manifestations. A high frequency of RNP, MSA, and MAA were found. People of black race and with childhood-onset disease had a higher prevalence of myositis. Our findings suggest that SLE patients of black race, with childhood-onset SLE, and who possess MSA or MAA should be routinely screened for myositis.

Successful use of rituximab in granulomatosis with polyangiitis with aortic inflammation.

Large-vessel inflammation, although rare, has been increasingly recognised as a complication of granulomatosis with polyangiitis (GPA) in recent years. The presentation is highly variable, ranging from an incidental finding to aortic dissection and rupture. Treatment has predominately consisted of a combination of cyclophosphamide and high dose corticosteroids with surgical intervention when indicated. We present the case of a 34-year-old male diagnosed with GPA after presenting with sinus and eye inflammation and the ensuing investigation revealed large vessel involvement that remarkably improved after 6 months of treatment with the combination of rituximab infusions, methotrexate and corticosteroids.

Transition Guide Dissemination to Foster Patient-Care Team Conversations: A Childhood Arthritis Rheumatology Research Alliance Transition Learning Collaborative Pilot Implementation Study.

OBJECTIVE: Uptake of evidence-informed health care transition processes among pediatric rheumatologists is low despite poor outcomes of transition from pediatric to adult care. We piloted a learning collaborative model to implement transition guides. We dually assessed implementation outcomes and changes in reported patient-care team discussions about transition. METHODS: This was a type II hybrid effectiveness-implementation pilot study of transition guide dissemination to patients at least 14 years old with rheumatic conditions across nine pediatric rheumatology centers in the Childhood Arthritis Rheumatology Research Alliance Transition Learning Collaborative. We evaluated implementation outcomes (feasibility, adaptations, and fidelity) and the proportion of patients surveyed that reported having discussions with their care team regarding transfer planning. RESULTS: Six sites were retained through the COVID-19 pandemic (below 70% target). Five out of six sites contributed outcome data (met 80% target) but with substantial heterogeneity in how transition guides were shared (eg, in-person, electronic messages, and posted flyers), and data were collected. The pooled proportion of respondents having discussed transfer planning with their care team was 39% preimplementation (n = 239; 95% confidence interval [CI] 32%-46%) and 55% postimplementation (n = 864; 95% CI 36%-73%). After implementation, there were significant increases in the likelihood of respondents recalling receiving a transition guide (odds ratio [OR] 2.58, 95% CI 1.35-4.92) and discussing transfer planning (OR 2.14, 95% CI 1.30-3.52), adjusted for age and site of care. CONCLUSION: Transition guide dissemination is a simple intervention associated with increased awareness among young people with rheumatic conditions and discussions with their care team about transition preparation. The learning collaborative model facilitated identification of several dissemination strategies adaptable to site-specific resources.

Implementation of Rheumatology Health Care Transition Processes and Adaptations to Systems Under Stress: A Mixed-Methods Study.

OBJECTIVES: Despite poor health care transition outcomes among young adults with pediatric rheumatic diseases, adoption of transition best practices is low. We sought to understand how structured transition processes were operationalized within pediatric rheumatology practices and what factors were perceived to enable adaptations during a global pandemic. METHODS: We conducted a mixed methods study of team leaders' experiences during an interim analysis of a pilot project to implement transition policy discussions at sites in the Childhood Arthritis and Rheumatology Research Alliance Transition Learning Collaborative. We combined quantitative assessments of organizational readiness for change (9 sites) and semistructured interviews of team leaders (8 sites) using determinants in the Exploration, Preparation, Implementation, Sustainment Framework. RESULTS: Engagement of nursing and institutional improvement efforts facilitated decisions to implement transition policies. Workflows incorporating educational processes by nonphysicians were perceived to be critical for success. When the pandemic disrupted contact with nonphysicians, capacity for automation using electronic medical record (EMR)-based tools was an important facilitator, but few sites could access these tools. Sites without EMR-based tools did not progress despite reporting high organizational readiness to implement change at the clinic level. Lastly, educational processes were often superseded by acute issues, such that youth with greater medical/psychosocial complexity may not receive the intervention. CONCLUSION: We generated several considerations to guide implementation of transition processes within pediatric rheumatology from the perspectives of team leaders. Careful assessment of institutional and nursing support is advisable before conducting complex transition interventions. Ideally, new strategies would ensure interventions reach youth with high complexity.

Health Literacy and Patient Activation in the Pediatric to Adult Transition in Systemic Lupus Erythematosus: Patient and Health Care Team Perspectives.

OBJECTIVE: To identify perceived health literacy (HL) and patient activation (PA) needs during the transition from pediatric to adult rheumatology among patients with childhood-onset systemic lupus erythematosus (cSLE). METHODS: Semistructured interviews of patients and health care professionals were conducted from November 2019 through May 2020, until thematic saturation was achieved. Interviews were audio-recorded, transcribed, coded, and analyzed using thematic analysis. RESULTS: Thirteen post-transition adult female participants with cSLE were recruited from a public safety-net hospital system or from private practice. Thirteen health care team members were recruited from two pediatric and four adult rheumatology clinical sites serving patients in the same metropolitan area. Patients and health care team members acknowledged numerous HL components as important to transition, including language fluency, education, SLE-specific knowledge, self-efficacy, and accurate knowledge of personal medical history. Our interviews found PA to be an important component of the transition process, driven by internalization of the implications of cSLE diagnosis, self-education, autonomy, introspection, and trustworthy doctor-patient relationships. Patients valued access to their online electronic medical record, recommended multimodal SLE-specific education materials, and desired increased access to social workers. Health care team members stressed the importance of early preparation for transition and use of mobile medical applications and endorsed interventions such as lupus camp and increased partnership with psychologists and social workers. CONCLUSION: HL and PA are perceived by patients and health care team members as substantially influencing transition success. Further research is needed to evaluate whether interventions to improve HL and PA positively influence cSLE transition outcomes.

Therapeutic recreation camps for youth with childhood-onset systemic lupus erythematosus: perceived psychosocial benefits.

BACKGROUND: The psychosocial burden of having a chronic disease can be substantial for adolescents with childhood-onset systemic lupus erythematosus (cSLE). Current literature is scarce on interventions that can improve psychosocial outcomes for this population. Therapeutic recreation camps have been proposed as a beneficial experience for chronically ill pediatric populations. However, their effective components have not been well characterized in patients with cSLE. In this study, we sought to understand the various components of the camp experience for adolescents with cSLE from both the patient and parent perspective. METHODS: We recruited patients with cSLE who had participated in one or more annual, weekend-long recreational lupus camp(s) near Dallas, Texas. Semi-structured in-depth telephone interviews were conducted from March-June 2020 with both the patients and parents. Questions focused on overall patient experience, psychosocial impact of camp participation, coping skills gained, and opportunities to prepare for the transition from pediatric to adult care. Interviews were coded and analyzed using inductive thematic analysis. RESULTS: We interviewed 9 current and former campers (ages 16-24), including a current camp counselor, and 3 of their parents separately. Reported benefits included a positive impact on social support through peer bonding, opportunities to develop coping mechanisms through structured activities and peer/medical staff interactions, opportunities for education about the cSLE disease experience, improved adherence through peer modeling, overall increase in self-efficacy, and better parental insight into the patient experience. Participants also provided suggestions for expansion and improvement in program development to optimize educational opportunities for both campers and parents. In addition, they advocated for longitudinal social support and community building. CONCLUSIONS: In this qualitative study, in which cSLE patients and their parents reflected on their experiences with therapeutic recreation camps, we found several perceived benefits impacting the patient and parent experience. Participants expressed a desire for more educational opportunities that could contribute to their successful transition from pediatric to adult care. Further studies are needed to demonstrate the effects of therapeutic recreation camps on the psychosocial health of this population.

Pediatric to Adult Transition Literature: Scoping Review and Rheumatology Research Prioritization Survey Results.

The transition from pediatric to adult care is the focus of growing research. It is important to identify how to direct future research efforts for maximum effect. Our goals were to perform a scoping review of the transition literature, highlight gaps in transition research, and offer stakeholder guidance on the importance and feasibility of research questions designed to fill identified gaps. The transition literature on rheumatic diseases and other common pediatric-onset chronic diseases was grouped and summarized. Based on the findings, a survey was developed and disseminated to pediatric rheumatologists and young adults with rheumatic diseases as well as their caregivers. The transitional care needs of patients, healthcare teams, and caregivers is well described in the literature. While various transition readiness scales exist, no longitudinal posttransfer study confirms their predictive validity. Multiple outcome measures are used alone or in combination to define a successful transition or intervention. Multimodal interventions are most effective at improving transition-related outcomes. How broader health policy affects transition is poorly studied. Research questions that ranked highest for importance and feasibility included those related to identifying and tracking persons with psychosocial vulnerabilities or other risk factors for poor outcomes. Interventions surrounding improving self-efficacy and health literacy were also ranked highly. In contrast to healthcare teams (n = 107), young adults/caregivers (n = 23) prioritized research surrounding improved work, school, or social function. The relevant transition literature is summarized and future research questions prioritized, including the creation of processes to identify and support young adults vulnerable to poor outcomes.

Clinical Team Perspectives on the Psychosocial Aspects of Transition to Adult Care for Patients With Childhood-Onset Systemic Lupus Erythematosus.

OBJECTIVE: The transition from pediatric to adult care for youth with childhood-onset systemic lupus erythematosus (SLE) is a vulnerable period. Adverse outcomes during this transition include gaps in care, unscheduled health care utilization, loss of insurance, and high disease activity. The objective of this study was to examine the clinical care teams' perspective on the psychosocial factors associated with transition outcomes, which are poorly understood in this population. METHODS: We conducted in-depth interviews with clinical care team members who interact with childhood-onset SLE patients during transfer from pediatric to adult rheumatology. A semistructured interview guide was used to prompt participants' perspectives about the psychosocial factors associated with the transition process for patients with childhood-onset SLE. Audio recordings were transcribed and analyzed using the constant comparative method. We stopped conducting interviews once thematic saturation was achieved. RESULTS: Thirteen in-depth interviews were conducted. Participants included pediatric rheumatologists (n = 4), adult rheumatologists from both academic and private practice settings (n = 4), nurses (n = 2), a nurse practitioner, a social worker, and a psychologist. We identified several themes deemed by clinical care teams as important during the transition, including the impact of the family, patient resilience and coping mechanisms, the role of mental health and emotional support, and the need for education, peer support, and social connectedness. CONCLUSION: We identified several psychosocial themes that clinical team members believe impact the transition of patients with childhood-onset SLE into adult care. The role of parental modeling, youth resilience, mental health and emotional care, improved childhood-onset SLE education, and structured peer support and social connectedness are highlighted, which may be amenable to interventions.

Time to First Completed Visit and Health Care Utilization Among Young Adults Transferring From Pediatric to Adult Rheumatologic Care in a Safety-Net Hospital.

OBJECTIVE: The transfer from pediatric to adult care for young adults is a vulnerable period. Our objectives were to quantify the time between the final pediatric and the first adult visit and to evaluate unscheduled utilization in care and progression to end-stage renal disease (ESRD) or death. METHODS: We conducted a retrospective analysis of pediatric patients transferring to a large adult rheumatology clinic. Outcomes included time to first completed adult visit, unscheduled health care utilization (hospitalizations and emergency department [ED] visits), and progression to ESRD or death. Multivariable regression models assessed variables predictive of outcomes of interest. RESULTS: A total of 141 pediatric patients who transferred care were identified: 77% female, 65% Hispanic, and 60% with connective tissue diseases (CTDs). The mean time between final pediatric and first completed adult rheumatology visit was 221 days (range 0-1,207 days). In regression modeling, we found that continued insurance coverage, younger age at referral, and referral from a pediatric rheumatologist were predictive of shorter time to completed adult visit (P < 0.005). Factors associated with hospitalizations and ED visits included CTD diagnosis and Black race (odds ratio [OR] 8.54 [95% confidence interval (95% CI) 1.84-39.58] and 3.04 [95% CI 1.02-9.12] for hospitalizations and OR 3.6 [95% CI 1.59-8.14] and 6.0 [95% CI 1.60-22.69] for ED visits, respectively). ESRD or death occurred among 15% of patients with a CTD. CONCLUSION: In pediatric patients transferring to an adult rheumatology clinic, continued insurance coverage and referral from a pediatric rheumatologist decreased delays in attending an adult visit; CTD and Black race were associated with high rates of unscheduled health care utilization.

Predictors of Adverse outcomes in patients with systemic lupus erythematosus transitioning to adult care.

BACKGROUND: The transition from pediatric to adult care is a vulnerable period for individuals with chronic diseases. We sought to identify risk factors associated with poor outcomes in patients with childhood-onset systemic lupus erythematosus (cSLE) who have transitioned to adult care. METHODS: A retrospective analysis of cSLE patients was performed. Outcomes of interest were development of end-stage renal disease (ESRD) or death and time to first hospitalization following final pediatric rheumatology visit. Multivariable logistic and Cox regression models were used. RESULTS: Of 190 patients with cSLE, 21 (11%) developed ESRD and 9 (5%) died following the final pediatric rheumatology visit. In logistic regression, public insurance, history of Child Protective Services involvement, and an unscheduled hospitalization during the final year in pediatric care were predictive of ESRD or death (odds ratio (95% confidence intervals (CI)) 6.7 (1.5-30.7), 6.6 (2.3-19.1), and 3.2 (1.3-8.3), respectively). Among 114 patients with healthcare utilization data, 53% had a hospitalization in adult care. In Cox regression analysis, a pediatric outpatient opioid prescription was associated with shorter time to adult hospitalization and White or Asian race was associated with longer time to adult hospitalization (hazard ratio (CI) 3.5 (1.7-7.0) and 0.1 (0.03-0.4), respectively). CONCLUSIONS: Risks factors associated with poor outcomes in adult care amongst patients with cSLE include public insurance, history of Child Protective Services involvement, unscheduled care utilization in pediatric care, pediatric outpatient opioid prescription, Black race and Hispanic ethnicity. Efforts to improve long-term outcomes among patients with cSLE should focus on these populations.

Advocacy 101: Engaging Rheumatology Fellows in Health Policy and Advocacy.

OBJECTIVE: Rheumatology fellowship programs lack formal curricular content to educate trainees about legislative and regulatory health care policies that have a profound impact on academic and community practices. Advocacy 101 was created as a program to address this gap and engage fellows-in-training (FIT) in health advocacy efforts. METHODS: A web-based survey was sent via the American College of Rheumatology (ACR) FIT listserve in July 2015 and April 2016. The survey queried respondents about their knowledge of and participation in health policy and advocacy. Survey results guided the design of an educational program called Advocacy 101 for FIT and program directors in conjunction with the ACR Advocates for Arthritis fly-in meeting. RESULTS: The survey response rate increased from 19% in 2015 (95 of 500 FIT) to 39% in 2016 (231 of 595 FIT). In 2015, the top reason for nonparticipation in health policy and advocacy efforts (64% of respondents) was lack of knowledge on how to get involved. This reason decreased to 39% of respondents in 2016. Other barriers to participation included lack of time and familiarity with the issues. Over the 2 years, FIT identified patient access to medication and insurance, and physician reimbursement as important advocacy issues. All participants of Advocacy 101 reported an increase in knowledge of health policy and the intent to stay involved. CONCLUSION: FIT regard health policy issues as important, but many are uncertain of how to participate in advocacy. Advocacy 101 is the first program designed to educate and engage rheumatology FIT in health policy and advocacy endeavors.

Pharmacological Approach to Managing Childhood-Onset Systemic Lupus Erythematosus During Conception, Pregnancy and Breastfeeding.

Pediatric patients often have poor pregnancy outcomes. Systemic lupus erythematosus predominantly impacts women in their second to fourth decade of life, with childhood-onset disease being particularly aggressive. Reproductive issues are an important clinical consideration for pediatric patients with systemic lupus erythematosus (SLE), as maintaining good disease control and planning a pregnancy are important for maternal and fetal outcomes. In this clinical review, we will consider the safety of medications in managing childhood-onset SLE during conception, pregnancy, and breastfeeding. The developing fetus is at highest risk for teratogenicity from maternal medications during the period of critical organogenesis, which occurs between the first 3-8 weeks following conception. Medications known to be teratogenic, leading to a specific pattern of malformations, include mycophenolic acid, methotrexate, and cyclophosphamide. These should be discontinued prior to a planned pregnancy or as soon as pregnancy is suspected. Hydroxychloroquine is safe and should be continued throughout pregnancy and breastfeeding in those without contraindications to it. Azathioprine and calcineurin inhibitors are felt to be compatible with pregnancy in usual doses and may be used prior to and throughout pregnancy and lactation. Non-fluorinated corticosteroids including methylprednisolone and prednisone are inactivated by the placenta and can be used if needed for maternal indication during gestation. Addition of aspirin may be considered around the 12th week of gestation for prevention of pre-eclampsia. Illustrative cases are presented that demonstrate management of adolescents with childhood-onset SLE through conception, pregnancy, and breastfeeding.
