Exploring the attitudes, concerns, and knowledge regarding COVID-19 vaccine by the parents of children with rheumatic disease: Cross-sectional online survey.

Background: Vaccination programs are effective strategies in preventing infectious diseases and controlling epidemics. Vaccination against SARS-CoV-2 in children has not yet been approved globally, and it is unclear what attitude families will take when it is approved in children. We aimed to investigate the underlying causes of vaccine acceptance, hesitation, and refusal, as well as concerns about the acceptability of the COVID-19 vaccine by parents of children with rheumatic diseases. Methods: Parents of children followed up with a diagnosis of rheumatic disease in the pediatric rheumatology outpatient clinic of a university hospital were included in the study. We applied a closed web based online survey conducted cross-sectionally and sent to the participants via mobile smartphones. Results: For fathers, mothers, and their children, acceptance rates for a COVID-19 vaccine were 64.2%, 57.7%, and 41.8%, respectively. In the multivariate analysis, factors affecting parents' acceptance of vaccines for their children were as follows: "Receiving antirheumatic medications regularly (AOR 5.40, 95% CI 1.10-26.33, p = 0.03), the previous history of getting special recommended vaccines (AOR 4.12, 95% CI 1.12-27.85, p = 0.03), relying on vaccines for ending pandemic (AOR 8.84, 95% CI 2.80-27.85, p = 0.001), complying with the pandemic measures entirely (AOR 5.24, 95% CI 1.46-18.74, p = 0.01)". The two most common reasons for vaccine rejection were fear of the side effects of the vaccine and its possible interaction with rheumatic drugs used by children. Conclusion: According to our survey, parents were more likely to accept a COVID-19 vaccine for themselves than their children. The success of COVID-19 vaccination programs sources highly on people's willingness to accept the vaccine. It is crucial to vaccinate children for achieving herd immunity and in terms of avoiding vaccine hesitancy. Larger data examining the causes of concerns in parents of both healthy children and children with chronic diseases should be delineated. (c) 2022 Elsevier Ltd. All rights reserved

Does immunosuppressive treatment entail an additional risk for children with rheumatic diseases? A survey-based study in the era of COVID-19

© 2020, Springer-Verlag GmbH Germany, part of Springer Nature.The aim of the research was to further extend current knowledge of whether severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) disease 2019 (COVID-19) entails a risk for children with various rheumatic diseases under immunosuppressive treatment. Telephone survey was administered by conducting interviews with the parents from May 1, 2020 to May 20, 2020. A message containing a link to the actual questionnaire was sent to their phones simultaneously. The medical records of the patients were reviewed for gathering information about demographic data, clinical follow-up, and treatments. Patients who were followed-up under immunosuppressive treatment (n = 439) were attempted to be contacted. The diagnostic distribution of patients (n = 414) eligible for the study was as follows: juvenile idiopathic arthritis (JIA) (n = 243, 58.7%), autoinflammatory diseases (n = 109, 26.3%), connective tissue diseases (n = 51, 12.3%), and vasculitis (n = 11, 2.7%). In the entire cohort, the mean age was 12 ± 4.7 years, and 54.1% (n = 224) were female. Nine patients have attended the hospital for COVID-19 evaluation, 6 of whom were in close contact with confirmed cases. One patient with seronegative polyarticular JIA, previously prescribed methotrexate and receiving leflunomide during pandemic was identified to be diagnosed with COVID-19. None, including the confirmed case, had any severe symptoms. More than half of the patients with household exposure did not require hospitalization as they were asymptomatic. Although circumstances such as compliance in social distancing policy, transmission patterns, attitude following contact may have influenced the results, immunosuppressive treatment does not seem to pose an additional risk in terms of COVID-19

Low disease activity state in juvenile-onset systemic lupus erythematosus

Objectives To determine the rate of achieving The Lupus Low Disease Activity State (LLDAS) in children with systemic lupus erythematosus (SLE) for tracing pertinent treatment modalities. Methods A total of 122 juvenile-onset SLE (jSLE) patients from six pediatric rheumatology centers in Turkey were enrolled in the study. LLDAS-50 was defined as encountering LLDAS for at least 50% of the observation time. According to the achievement of LLDAS-50, clinical features, immunological profiles, and treatments of patients with jSLE have been revealed. Results LLDAS of any duration was achieved by 82% of the cohort. Although only 10.8% of the patients achieved remission, 68.9% reached LLDAS-50. A significant difference was found between patients who reached LLDAS-50 and those who did not, in terms of the time to reach low-dose corticosteroid treatment (p = 0.002), the presence of subacute cutaneous findings (p = 0.007), and the presence of proteinuria (p = 0.002). Both of the groups were under similar treatment approaches. However, the number of patients being treated with corticosteroids at the last visit was found to be significantly higher in patients who achieved LLDAS-50 (p<0.001). Conclusion Targeting LLDAS in jSLE, even with long-term, low-dose corticosteroid use, seems to be an achievable goal in clinical practice

Rhupus syndrome in children: A multi-center retrospective cohort study and literature review

Objective: In this study, we aimed to evaluate the characteristics of pediatric rhupus patients including all the related series in the literature. Methods: Thirty pediatric patients with rhupus syndrome from 12 different centers in Turkey were included in this study. The literature was also reviewed for pediatric patients with rhupus syndrome. Results: The most prominent phenotype of these 30 patients was juvenile idiopathic arthritis (JIA) (60%) at the disease onset and SLE (73.3%) at the last visit. Major SLE-related organ involvements were skin (80%), hematological system (53.3%), and kidney (23.3%). Arthritis was polyarticular (73.3%), asymmetric (66.7%), and erosive (53.3%) in most patients. Hydroxychloroquine (100%), glucocorticoids (86.7%), and mycophenolate mofetil (46.7%) were mostly used for SLE, while glucocorticoids (76.6%), methotrexate (73.3%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (57.6%) were mainly preferred for JIA. Our literature search revealed 20 pediatric patients with rhupus syndrome (75% were RF positive). The most prominent phenotype was JIA (91.7%) at the disease onset and SLE (63.6%) at the last visit. Major SLE-related organ involvements were skin (66.7%), hematological system (58.3%), and kidney (58.3%). Arthritis was polyarticular (77.8%), asymmetric (63.6%), and erosive (83.3%) in most patients. Glucocorticoid (100%), hydroxychloroquine (76.9%), and azathioprine (46.2%) were mostly used for SLE, while methotrexate (76.9%) and NSAIDs (46.2%) were mainly preferred for the JIA phenotype. Conclusion: Our study is the largest cohort in the literature evaluating pediatric rhupus cases. Most of the pediatric patients had polyarticular, asymmetric, and erosive arthritis, as well as organ involvements associated with SLE, including the skin, hematological system, and kidney

Differences and similarities of multisystem inflammatory syndrome in children, Kawasaki disease and macrophage activating syndrome due to systemic juvenile idiopathic arthritis: a comparative study

To compare the clinical and laboratory findings of multisystem inflammatory syndrome in children (MIS-C), patients with Kawasaki disease (KD) and with macrophage activating syndrome due to systemic juvenile idiopathic arthritis (sJIA-MAS) on real-life data. Patients diagnosed with MIS-C, KD, and sJIA-MAS from 12 different centers in Turkey who were followed for at least 6 months were included in the study. Demographic, clinical, and laboratory findings of all patients were analyzed. A total of 154 MIS-C, 59 KD, and 31 sJIA-MAS patients were included. The median age of patients with MIS-C were higher than those with KD while lower than those with sJIA-MAS (8.2, 3, 12 years, respectively). Myalgia (39.6%), cardiac (50.6%), gastrointestinal (72.7%), and neurological (22.1%) involvements were more common in patients with MIS-C compared to others. MIS-C patients had lower levels of lymphocyte (950 vs 1700 cells/mu l) and thrombocyte (173,000 vs 355,000 cells/mu l) counts and higher pro-BNP (1108 vs 55 pg/ml) levels than KD. Ferritin levels were higher in patients with MIS-C compared to patients with KD while they were lower than patients with sJIA-MAS (440, 170, 10,442 ng/ml, respectively). Patients with MIS-C had a shorter duration of hospitalization than sJIA-MAS (p = 0.02) while they required intensive care unit admission more frequently (55 vs 8 patients, p < 0.001). The median MAS/sJIA score of MIS-C patients was - 1.64 (- 5.23 to 9.68) and the median MAS/sJIA score of sJIA-MAS patients was -2.81 ([- 3.79] to [- 1.27]). MIS-C patients displayed certain differences in clinical and laboratory features when compared to KD and sJIA-MAS. Definition of the differences and similarities between MIS-C and the other intense inflammatory syndromes of childhood such as KD and MAS will help the clinicians while making timely diagnosis
