Abstract: Takayasu arteritis (TA) is the third most common vasculitis of childhood and is extreme-ly rare. It is mainly characterized by chronic, autoimmune, and granulomatous inflammation of the aorta and its major branches. Women under 40 years of age are mostly affected. It occurs for the first time in childhood in about 30% of affected individuals. Initially, it presents nonspecific consti-tutional findings. Since there is no specific laboratory finding, diagnosis is challenging. The gold standard imaging method for diagnosis is conventional angiography. Delay in diagnosis can cause devastating consequences. Therefore, in cases presenting with nonspecific findings, with hyperten-sion and high acute phase reactants, the diagnosis should be suspected and confirmed with appro-priate imaging method, and treatment should be started immediately. Immunosuppressive agents are the mainstay of the treatment. Biological agents are successful in refractory cases, and endovascular revascularization methods are used in the treatment of complications.

Our aim was to investigate the possible relationship between the serum S100A12 and Toll-like receptor 4 (TLR4) levels, and the activity of familial Mediterranean fever (FMF) and juvenile idiopathic arthritis (JIA) in accordance with the routine biochemical parameters. Furthermore, the effectiveness of these 2 biomarkers in distinguishing FMF from JIA has been evaluated.Sixty-nine children with FMF, 68 children with JIA, and 35 healthy children were included in this study. S100A12 and TLR4 levels were measured by the sandwich enzyme-linked immunosorbent assay technique.In the FMF patient group, serum S100A12 level was found to be significantly higher than in both the JIA and control groups (P = .000 and P = .000, respectively). Although S100A12 levels were higher in the attack period compared to the attack-free period, this increase was not statistically significant (P .05). TLR4 levels were statistically significantly higher in the attack period compared to the attack-free period in children with FMF (P .05). Although there was no relationship between S100A12 levels and disease activity, there is a clear correlation between S100A12 and the Auto-Inflammatory Disease Activity Index in attack-free FMF patients (r = 0.612 P = .000).Serum S100A12 levels were not found to be a potentially valuable biomarker for assessing disease activity in either FMF or JIA. However, TLR4 levels were found to be a valuable biomarker for assessing disease activity in children with FMF. Further research which includes serial monitoring of S100A12 and TLR4 levels in a large cohort will provide detailed information about accuracy of these 2 potential biomarkers in both patients group.

Periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome is one of the most common autoinflammatory fever disorders in the childhood which may co-exists with familial Mediterranean fever (FMF) causing treatment complexity. As the role of surgery in PFAPA syndrome is still controversial, in this paper, our aim is to present our results of tonsillectomy/adenotonsillectomy in the treatment of PFAPA syndrome. Archives of a tertiary care hospital were investigated for patients who underwent tonsillectomy or adenotonsillectomy due to PFAPA Syndrome between 2010 and 2020. 344 patients were found but only 281 of them were accessible. Through phone call interview and chart review methods, preoperative and postoperative the number and severity of the attacks and general satisfaction after the operation were recorded and analyzed. Also, patients with concomitant FMF were analyzed separately. A total of 281 patients were included in the study. There was no improvement in 10 (3.55%) patients. Eight (2.84%) patients showed mild improvement, 29 (10.32%) patients had moderate improvement and 234 (83.27%) patients had full recovery after tonsillectomy. There were 266 PFAPA patients without FMF. No improvement, mild improvement, moderate improvement, and full recovery in this patient group were 5 (1.9%), 6 (2.3%), 25 (9.4%) and 230 (86.5%), respectively. FMF was present in 5.33% (15/281) of the patients. In PFAPA + FMF group 5 patients had no improvement (33.3%), 2 had mild improvement (13.3%), 4 had moderate improvement (26.7%) and 4 had full recovery (26.7%). Benefit of tonsillectomy was significantly lower in the patients with concomitant FMF when compared to the patients who did not have FMF (p 0.001). Age of diagnosis, age of operation, severity of the disease, type of operation, and gender were found to have no significant relationship with the benefit from surgery (p 0.05). According to the findings of this study, tonsillectomy is an effective long-term treatment for PFAPA syndrome with success rate of 83.27%. Also, preoperatively FMF should be considered in these patients, which dramatically reduces surgical efficacy.

ObjectiveIn this study, we aimed to screen 31 genes (C1QA, C1QB, C1QC, C1R, C1S, C2, C3, TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR, DNASE1, DNASE1L3, PRKCD, ACP5, SLC7A7, IFIH1, TMEM173, ISG15, CYBB, FAS, FASLG, KRAS, NRAS, MAN2B1, PEPD, PTPN11, RAG2, and SHOC2), that we have categorized under the umbrella term “monogenic lupus” using a targeted next-generation sequencing (NGS) panel in 24 individuals with early-onset (≤10 years of age) systemic lupus erythematosus (SLE) and in 24 patients with late-onset (>10 years of age) disease.MethodsA total of 48 SLE patients (24 with disease onset ≤10 years of age and 24 with disease onset >10 years of age) were included. Patients with late-onset disease have been used as patient controls. Sequencing was carried out using 400 bp kit on the Ion S5 system.ResultsAmong the 48 patients, three had one pathogenic variant and 45 patients had at least one rare variant classified as benign, likely benign or variant of unknown significance (VUS). In all three patients with a pathogenic variant, the onset of disease was before 10 years of age. Two patients (they were siblings) carried C1QA homozygote pathogenic allele (p.Gln208Ter, rs121909581), and one patient carried PEPD heterozygote pathogenic allele (p.Arg184Gln, rs121917722).ConclusionWe demonstrated a pathogenic variant in our target gene panel with a frequency of 9.52% in patients with a disease onset ≤10 years of age. All patients with early-onset SLE phenotype, irrespective of a positive family history for SLE or parental consanguinity, should be scanned for a single-gene defect by a targeted gene panel sequencing. With the discovery of many single-gene defects and ongoing efforts to identify novel genes in SLE, similar gene panels including even more genes will possibly become more necessary and practical in the future.

Objective We aimed to find out the asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence among pediatric patients with rheumatic diseases and healthy children and to compare them with each other. Methods Patients with familial Mediterranean fever (FMF), juvenile idiopathic arthritis (JIA), and juvenile systemic lupus erythematosus (jSLE) and healthy children as healthy control (HC) group who remained asymptomatic during the pandemic are examined by ELISA immunoglobulin (Ig) A and IgG tests in this cross-sectional study. Results Overall, 149 subjects (90 females) were included in the study. While IgA was positive in 15 subjects (10%) (HC: 8, jSLE: 3, FMF: 2, JIA: 2; p = 0.196), IgG was positive in 14 subjects (9.4%) (HC: 7, JIA: 5, FMF: 1, jSLE: 1; p = 0.156). Nineteen subjects (12.75%) were IgA or IgG positive (HC: 8, JIA: 5, jSLE: 3, FMF: 3; p = 0.644). Although not significant, seropositivity was more often in HC group. Both IgA and IgG positivity were not found to be related to age, sex, underlying rheumatic diseases, and received treatments of the patients. Conclusion We revealed that patients with childhood-onset rheumatic diseases, even if they receive immunosuppressive medication such as biologic or conventional disease-modifying anti-rheumatic drugs, might have an asymptomatic SARS-CoV-2 infection, similarly to their healthy peers. Key points• Although it has been already known that children are most likely to have asymptomatic SARS-CoV-2 infection, there is a lack of data on the disease course of children with rheumatic disease.• There was no significant difference regarding the asymptomatic SARS-CoV-2 seropositivity rates between healthy children and the patients with childhood-onset rheumatic diseases.• Patients with childhood-onset rheumatic diseases, even if they receive immunosuppressive medication, might have asymptomatic SARS-CoV-2 infection, similarly to their healthy peers.

Possible interactions of the neuropeptide oxytocin and the sex hormone estradiol may contribute to previously observed sex-specific effects of oxytocin on resting-state functional connectivity (rsFC) of the amygdala and hippocampus. Therefore, we used a placebo-controlled, randomized, parallel-group functional magnetic resonance imaging study design and measured amygdala and hippocampus rsFC in healthy men (n = 116) and free-cycling women (n = 111), who received estradiol gel (2 mg) or placebo before the intranasal administration of oxytocin (24 IU) or placebo. Our results reveal significant interaction effects of sex and treatments on rsFC of the amygdala and hippocampus in a seed-to-voxel analysis. In men, both oxytocin and estradiol significantly decreased rsFC between the left amygdala and the right and left lingual gyrus, the right calcarine fissure, and the right superior parietal gyrus compared to placebo, while the combined treatment produced a significant increase in rsFC. In women, the single treatments significantly increased the rsFC between the right hippocampus and the left anterior cingulate gyrus, whereas the combined treatment had the opposite effect. Collectively, our study indicates that exogenous oxytocin and estradiol have different region-specific effects on rsFC in women and men and that the combined treatment may produce antagonistic effects.

Introduction: Neuropsychiatric (NP) involvement is a restricted area in juvenile-onset systemic lupus erythematosus (jSLE). Aim: To investigate the prevalence, demographic and clinical features, and outcomes of the neurological involvement in the Turkish jSLE population. Methods: This study was based upon 24 referral centers' SLE cohorts, multicenter and multidisciplinary network in Turkey. Patient data were collected by a case report form which was standardized for NP definitions according to American Collage of Rheumatology (ACR). Systemic Lupus International Collab-orating Clinics/American College of Rheumatology Damage Index (SDI) neuropsychiatric part was used to determine NP damage. Variables were evaluated Ward's hierarchical clustering analyses, univariate, and multivariate logistic regression analyses. Results: A hundred forty-nine of 1107 jSLE patients had NP involvement (13.5%). The most common NPSLE findings were headache (50.3%), seizure (38.3%), and acute confusional state (33.6%). Five clusters were identified with all clinical and laboratory findings. The first two clusters involved neuropathies, demyelinating diseases, aseptic meningitis, and movement disorder. Cluster 3 involved headache, activ-ity markers and other SLE involvements. Idiopathic intracranial hypertension, cerebrovascular disease, cognitive dysfunction, psychiatric disorders and SLE antibodies were in the fourth, and acute confusional state was in the fifth cluster. In multivariate analysis, APA positivity; OR: 2.820, (%95CI: 1.002-7.939), P: 0,050, plasmapheresis; OR: 13.804 (%95CI: 2.785-68.432), P: 0,001, SLEDAI scores; OR: 1.115 (%95CI: (1.049-1.186), P: 0,001 were associated with increased risk for neurologic sequelae. Conclusion: We detected the prevalence of juvenile NPSLE manifestations in Turkey. We have identified five clusters that may shed light pathogenesis, treatment and prognosis of NP involvements. We also determined risk factors of neurological sequelae. Our study showed that new definitions NP involvements and sequelae for childhood period are needed.

Aim The current study was undertaken to evaluate the influence of breastfeeding on the development and outcome measures of juvenile idiopathic arthritis (JIA). The second aim was to determine the consequences of particular sociodemographic and sociocultural characteristics and nutritional behavior of early childhood on JIA. Methods The study includes the patients diagnosed with JIA and regularly followed up at the Department of Pediatric Rheumatology in Istanbul University-Cerrahpasa. The comparison group consisted of healthy subjects and patients with juvenile systemic lupus erythematosus (jSLE). A face-to-face survey method was conducted with the parents of the participants between February 1, 2021, and September 1, 2021. Results The mean age of the JIA cohort (n = 324) was 12.2 +/- 4.7 years, with a female ratio of 64.8%. The breastfeeding rate differed from the control groups (253 healthy subjects and 88 patients with jSLE) but was higher with a value of 94.8%. There was no difference between the groups (P = .097, P = .064) or within the subgroups of JIA (P = .12) regarding breastfeeding duration. Cow\"s milk introduction time (P = .02, P = .0001), household pet-keeping (P = .001), income level (P = .0001), maternal literacy (P = 0.013) made a statistical difference vs the control groups. Conclusion No relationship was established between the rate or duration of breastfeeding and the development or severity of JIA. The early introduction of cow\"s milk was found to be higher in the patient cohorts. The income level and maternal literacy appeared to be relevant with the high disability and damage scores, and frequent relapse rates. Secondhand smoking, higher in JIA, may prompt the basis of primary preventable strategies in JIA.

Insulin resistance (IR) has been described in adults with systemic lupus erythematosus (SLE), though its mechanism has not been fully clarified. In this study, it was aimed to investigate insulin sensitivity for the first time in children with juvenile SLE (jSLE) by considering the effect of the already known contributing factors of IR.This is a cross-sectional study including 43 patients with jSLE and the same number of healthy controls matched for age, gender, pubertal stage, body mass index, and physical activity level. IR, as calculated by both homeostatic model assessment for insulin resistance (HOMA-IR) and a relatively new method, triglyceride glucose (TyG) index, was compared between the patients and their matched controls, also among the patients stratified by disease duration, corticosteroid use, and disease activity.Insulin resistance in the patient group was higher than the controls according to both HOMA-IR and TyG index (p 0.001 for both). In the patient group, no significant effect of disease duration, corticosteroid use, disease activity, and levels of anti-dsDNA, anti-cardiolipin IgM, anti-cardiolipin IgG, C3, and C4 on IR was demonstrated.Children with jSLE were found to have higher IR even after neutralizing the effects of the contributing factors which are expected to aggravate IR. This elevation in IR in jSLE seems not to be associated with corticosteroid use, disease duration, disease activity, or autoantibody levels. Thus, the presence of IR in jSLE cannot be explained solely with neither the already known contributing factors nor the increased inflammation of the disease. Key Points • In this study, insulin sensitivity was investigated for the first time in children with jSLE. • Children with jSLE have higher insulin resistance than healthy ones. • Insulin resistance in children with jSLE is independent of corticosteroid use, disease duration, disease activity or autoantibody, and complement levels.

The effects of biological disease-modifying antirheumatic drugs (bDMARDs) in the clinical course of COVID-19 on children with underlying rheumatologic diseases have not been fully demonstrated. To evaluate the course of COVID-19 infection in patients with rheumatic disease receiving bDMARD treatment. This was a retrospective, multicenter study conducted in pediatric patients infected by SARS-CoV-2 and under bDMARDs therapy. The study population consisted of 113 patients (72 female/41 male). The mean age of the patients was 12.87 ± 4.69 years. The primary diagnosis of the cohort was as follows: 63 juvenile idiopathic arthritis, 35 systemic autoinflammatory diseases, 10 vasculitides, and five cases of connective tissue diseases. The mean duration of the primary disease was 4.62 ± 3.65 years. A total of 19 patients had additional comorbid diseases. Thirty-five patients were treated with canakinumab, 25 with adalimumab, 18 with etanercept, 10 with infliximab, nine with tocilizumab, six with rituximab, four with anakinra, three with tofacitinib, and one with abatacept. The median exposure time of the biological drug was 13.5 months. Seventy-one patients had symptomatic COVID-19, while 42 were asymptomatic. Twenty-four patients required hospitalization. Five patients presented with MIS-C. The hospitalized patients were younger and had a shorter duration of rheumatic disease compared to ambulatory patients, although the difference was not statistically significant. Steroid usage, presence of fever, and dyspnea were more common among the hospitalized patients. A worsening in the course of both COVID-19 and current disease was not noticed under bDMARDs, however, to end with a strong conclusion multicentric international studies are required. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

Having a child with a chronic illness is a source of stress for the whole family, especially the primary caregiver. The aim of this study was to evaluate the associations between caregiver burden and both the caregiver's and child's psychological symptoms in a cohort of children with systemic lupus erythematosus (SLE).Thirty-four patients (aged 9-18 years) with childhood-onset SLE and their caregivers participated in this study. The control group was composed of healthy children and their caregivers. Questionnaires were used to evaluate caregiver burden and the psychological status of parents and children and adolescents with and without SLE.No significant difference was found between the study and control groups for caregiver burden, anxiety and depression in parents, and psychological status in children. Caregiver burden was positively correlated with parent's depression, anxiety, and behavioral and peer problems of the children, and it was negatively correlated with the children's prosocial behaviors. According to regression analyses, the parents' depression and children's peer relationship had a positive effect on caregiver burden scores.Physicians should be aware of the presence of psychological symptoms in patients with childhood-onset SLE and their caregivers because it can affect caregiver burden and the caregiver's psychological state. Key points •Caregiver burden was positively correlated with parent's depression and anxiety. •Caregiver burden was positively correlated with children's behavioral and peer problems. •Caregiver burden was negatively correlated with child's prosocial behaviors.

Our aim in this study is to reveal the frequency of febrile seizures in patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome and to compare it to normal population.Patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome, who were diagnosed accord- ing to Turkish pediatric Familial Mediterranean Fever diagnostic criteria and Marshall criteria, were enrolled to the study. A form containing questions about febrile seizures history was pre- pared for Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome patients. Demographic data and febrile seizures history of Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis patients were obtained by calling the parents by phone. Familial Mediterranean Fever patients were randomly selected during their routine follow-up. The frequency of febrile seizures in both disease groups was compared with the prevalence of previous febrile seizures studies in the general population in Turkey.A total of 417 Familial Mediterranean Fever and 152 Periodic Fever, Aphthous stomati- tis, Pharyngitis, cervical Adenitis subjects were recruited to the study. The frequency of febrile seizures in Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome was similar (8.4% vs. 8.6%; P.05). The frequency of febrile seizures in Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome patients was found to be significantly higher than the frequency in general population (8.4% vs. 4.4%) [P.0001, OR: 1.99 (CI: 1.4-2.8)]; (8.6% vs. 4.4%) [P.01, OR: 2.03 (CI: 1.1-3.6)], respectively.The frequency of febrile seizures in patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome was found to be significantly higher than in the general population. This increased frequency of febrile seizures in both periodic syndromes seems to be a result of recurrent fever.

Although most of the autoinfammatory disorders have a confirmed genetic cause, periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome still has an unknown genetic background. However, familial cases of PFAPA syndrome have been reported suggesting a genetic its basis. PFAPA syndrome may also be considered an infammasome disorder as variants in infammasome-associated genes such as CARD8, NLRP3, and MEFV have been reported to contribute to the disease.Polymerase chain reaction (PCR)/Sanger sequencing analysis was performed for the detection of the variations in 71 PFAPA patients and 71 healthy controls. NLRP3 concentrations in serum were measured in 71 PFAPA patients and 71 healthy controls.No statistically significant differences were observed in the allele or genotype frequencies of the NLRP3 polymorphisms between the controls and patients (P 0.05). We found no significant differences for NLRP3 serum levels between PFAPA patients and controls (p 0.05). Mutations in the MEFV gene were detected in 32.5% of our patients (13/40).It seems that the synergistic effect of different genes plays a role in the formation of PFAPA syndrome. For this reason, it may be useful to examine the presence of mutations in genes such as NLRP3, MEFV, and CARD8 together while investigating the genetics of PFAPA syndrome. Key points • Familial cases of PFAPA syndrome have been reported suggesting a genetic basis for this syndrome. • Elevated serum or plasma levels of IL-1β, IL-6, and IL-18 have been demonstrated during PFAPA flares in several studies. • It seems that the synergistic effect of different genes plays a role in the formation of PFAPA syndrome.

Objectives: Juvenile systemic sclerosis is a rare childhood disease. Three disease activity indices have been published for adult patients with systemic sclerosis: the European Scleroderma Study Group Index, a modified version of the European Scleroderma Study Group Index and the revised European Scleroderma Trials and Research index. The objective of this study was to determine the feasibility and performance of the three disease activity indices in a prospectively followed cohort of patients with juvenile systemic sclerosis. Methods: The analysis cohort was selected from the prospective international inception cohort enrolling juvenile systemic sclerosis patients. The correlation of the disease activity indices with the physicians’ and the patients’ global assessment of disease activity was determined. The disease activity indices were compared between patients with active and inactive disease. Sensitivity to change between 6- and 12-month follow-up was investigated by mixed models. Results: Eighty percent of the 70 patients had a diffuse cutaneous subtype. The revised European Scleroderma Trials and Research index was highly correlated with the physician-reported global disease activity/parents-reported global disease activity (r = 0.74/0.64), followed by the European Scleroderma Study Group activity index (r = 0.61/0.55) and the modified version of the European Scleroderma Study Group activity index (r = 0.51/0.43). The disease activity indices significantly differed between active and inactive patients. The disease activity indices showed sensitivity to change between 6- and 12-month follow-up among patients who improved or worsened according to the physician-reported global disease activity and the parents-reported global disease activity. Conclusion: Overall, no disease activity score is superior to the other, and all three scores have limitations in the application in juvenile systemic sclerosis patients. Furthermore, research on the concept of disease activity and suitable scores to measure disease activity in patients with juvenile systemic sclerosis is necessary in future.

Aim To compare childhood-onset (c-TAK) versus adult-onset Takayasu arteritis (a-TAK) patients for vascular involvement, disease activity, damage, and treatment. Methods Patient charts from two tertiary-care centers of a pediatric and adult rheumatology clinic were reviewed. Adult patients diagnosed before the age of 18 years were included in the childhood-onset group. The activity was assessed with the physician's global assessment (PGA) and Indian Takayasu Clinical Activity Score (ITAS). The damage was evaluated with Takayasu Arteritis Damage Score (TADS) and Vasculitis Damage Index (VDI). Results Twenty-four c-TAK (follow-up duration: 53 months) and 117 a-TAK patients (follow-up duration: 68 months) were analyzed. Aorta involvement was more prevalent (79% vs. 33%), and the median PGA score was higher in the c-TAK group (9 vs. 7), whereas the mean Indian Takayasu Arteritis Score was similar (14 vs. 13) among both groups. Median VDI score was lower for c-TAK patients (4 vs. 5), whereas TADS was similar for children and adults (8 vs. 8). Higher incidence of glucocorticoid related side-effects, a longer time to diagnosis and upper extremity claudication seemed to account for higher VDI scores in adults. Conclusion Aorta involvement was more common among children with TAK, whereas upper extremities were relatively spared. Biologic agents were used more commonly among children which may be explained by higher rates of aortic involvement. However, c-TAK patients did not have greater cumulative damage.

This study aimed to evaluate the psychological symptoms of children and adolescents with rheumatological diseases (RD) and their parents during the outbreak. A web-based questionnaire survey was conducted in a cross-sectional design in RD patients and healthy controls. The Hospital Anxiety and Depression Scale was used to evaluate parental psychiatric status; while the State-Trait Anxiety Inventory for Child was used for children. Four hundred and fifty-nine patients with RD and their parents completed the present study, as well as 336 healthy peers. The age and gender of the children were similar across groups. Under 12 years of age, the trait anxiety of the children and the psychological symptoms of parents were similar across groups; while over 13 years of age, anxiety and depression scores of the parents, as well as trait anxiety of the children were higher than the control groups' (7.3 +/- 3.4 vs 6.3 +/- 3.8, p = 0.006 for parental anxiety; 6.6 +/- 3.8 vs. 5.3 +/- 3.9, p < 0.001 for parental depression; 36.1 +/- 8.7 vs. 33.3 +/- 7.9, p = 0.002 for child trait anxiety). In patient group, there were no differences in scale scores according to variables such as rheumatological disease diagnosis, the consulting of doctor for treatment, thinking that RD increases the risk of COVID-19, the history of rheumatic disease attack during the pandemic process, and the use of biological agents. The children's trait anxiety was positively correlated with their parents' anxiety (r = 0.414, p < 0.001) and depression (r = 0.300, p < 0.001) scores. These findings suggest that clinicians should pay attention to the psychiatric symptoms of both children with RD and their parents during the pandemic.

Systemic lupus erythematosus (SLE) is a chronic inflammatory disease characterised by the presence of various autoantibodies. Mild cognitive impairment developing in patients without significant neuropsychiatric (NP) symptoms was thought to be the result of immune-mediated myelinopathy. We aimed to determine the role of myelin oligodendrocyte glycoprotein antibody (MOG-Ab) in the neurological manifestations of childhood-onset SLE (cSLE) and if there is a correlation between various metabolite peaks in magnetic resonance spectroscopy (MRS) and myelinopathy.MOG-Ab levels were studied in all healthy subjects (n=28) and in all patients with (NPSLE=9) and without (non-NPSLE=36) overt neuropsychiatric manifestations. Twenty patients (all had a normal-appearing brain on plain magnetic resonance) in non-NPSLE and 20 subjects in healthy group met the MRS imaging standards for evaluation in which normal appearing brain on plain MR.A total of 45 cSLE (36 non-NPSLE and 9 NPSLE) subjects and 28 healthy children were recruited to the study. The mean age of the SLE patients at study time was 16.22±3.22 years. MOG-Ab was not detected in cSLE or in healthy group. There was no significant difference between the non-NPSLE group and healthy subjects in terms of choline, N-acetyl aspartate (NAA), creatine, NAA/creatine, and choline/creatine.There was no association of MOG-Ab with cSLE, whether NP manifestations were present or not. A causal relationship between immune-mediated myelinopathy and cognitive impairment could not be suggested, since there has been no patient with positive MOG-Ab and there has been no difference in choline, choline/creatine between groups.

(1) Background: We aimed to describe the clinical features and outcomes of coronavirus disease-2019 (COVID-19) in children and late adolescents with inflammatory rheumatic diseases (IRD) and to measure their severity risks by comparing them with healthy children. (2) Methods: Among children and late adolescents found to be severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) positive via polymerase chain reaction (PCR) test, IRD patients with an at least six-months follow-up duration, and healthy children were included in the study. Data were obtained retrospectively. (3) Results: A total of 658 (339 (51.5%) females) (healthy children: 506, IRD patients: 152) subjects were included in the study. While 570 of 658 (86.6%) experienced COVID-19-related symptoms, only 21 (3.19%) required hospitalization with a median duration of 5 (1–30) days. Fever, dry cough, and fatigue were the most common symptoms. None of evaluated subjects died, and all recovered without any significant sequelae. The presence of any IRD was found to increase the risk of both hospitalization (OR: 5.205; 95% CI: 2.003–13.524) and symptomatic infection (OR: 2.579; 95% CI: 1.068–6.228). Furthermore, increasing age was significantly associated with symptomatic infection (OR: 1.051; 95% CI: 1.009–1.095). (4) Conclusions: Our study emphasizes that pediatric rheumatologists should monitor their patients closely for relatively poor COVID-19 outcomes.

Humanity has recently gained a novel foe named coronavirus disease 2019. Although data so far mostly suggest that children are more likely to have a favorable disease course, new concerns have been raised because of recently reported pediatric cases with hyperinflammatory conditions resembling Kawasaki disease, toxic shock syndrome, and macrophage activation syndrome/hemophagocytic lymphohistiocytosis. Because the increasing evidence suggests that this recent hyperinflammatory condition emerged in the coronavirus disease 2019 era is a distinct clinical picture, the Centers for Disease Control and Prevention named this novel disease multisystem inflammatory syndrome in children. Even if this novel disease is rare, it seems to be highly fatal. Therefore, it is urgent to understand the pathogenesis of the disease to be able to establish the appropriate treatment regimes. Concerns regarding the diagnostic process and the management of the disease have been raised even among pediatricians. Therefore, we aimed to clarify this newly occurring enigma based on the current literature and our clinical insights.

To evaluate the efficacy and safety of anti-interleukin (IL)-6 receptor antibody tocilizumab (TCZ) as a treatment option of juvenile systemic sclerosis (JSS). Nine JSS patients were assigned to a TCZ, additionally to conventional treatment (steroids, methotrexate, mycophenolate-mofetil). The modified Rodnan skin score (mRSS), carbon-monoxide diffusion capacity (DLCO), thorax high-resolution tomography (HRCT), patient global assessment (PGA) and Juvenile Systemic Sclerosis Severity (J4S) score were used to explore the efficacy of treatment. Nine JSS patients were treated with TCZ with a median treatment duration of 10 (1-21) months. Nine patients (77.8%) had radiologically confirmed improvement on thorax HRCT, 7 (77.8%) had decreased PGA (mean pre-treatment PGA 3.7 vs. 2.3 post-treatment PGA 2), 6 (66.7%) had increased DLCO (mean pre-treatment DLCO 69.14% vs. post-treatment DLCO 79.50%) after the TCZ treatment. In all patients mRSS and the J4S decreased: 26.1 vs. 19.7 and 8.2 vs. 4.7, respectively. Changes in mRSS, DLCO, PGA and J4S were statistically significant: p = 0.012, 0.04, 0.026 and 0.007, respectively. All patients tolerated well TCZ treatment. JSS is a rare condition characterized with skin fibrosis and internal organ involvement. Tocilizumab represents a potential treatment option for patients unresponsive to conventional treatment. Long-term prospective studies with higher number of patients are needed to provide more relevant data.

Juvenile spondyloarthropathy is an umbrella term for a group of childhood rheumatic diseases that can cause chronic arthritis extending to the axial skeleton before the age of 16. Although ankylosing spondylitis has aortic involvement as one of its most important effects, this relationship has not been extensively studied in children with juvenile spondyloarthropathy. Here, a cross-sectional study of the elastic properties of the aorta of 43 patients with juvenile spondyloarthropathy and 19 healthy controls is reported. Aortic stiffness assessed by echocardiography was used to predict the presence of aortitis, supplemented by pulsed-wave tissue Doppler indices. The right ventricular fractional area change was found to be significantly lower in the patients with juvenile spondyloarthropathy than in the healthy controls; aortic strain and distensibility were also significantly lower, and aortic stiffness index β was significantly higher; and the aortic root diameter change was significantly lower. According to HLA-B27 positivity, there was no difference in the stiffness parameters between the two groups. There was a significant correlation between juvenile Ankylosing Spondylitis Disease Activity Index and aortic diameter change, between juvenile Ankylosing Spondylitis Disease Activity Index and aortic stiffness. Thus, juvenile spondyloarthropathy is linked to high aortic stiffness parameters.

To determine the frequency of Th2-mediated allergic diseases (AD) in mainly Th1-driven juvenile idiopathic arthritis (JIA) subtypes.Ninety-nine JIA patients and 128 control subjects were enrolled in a prospective case-control study. All subjects were assessed with standard allergy questionnaire, complete blood cell count, and total serum immunoglobulin (sIg) E. sIgs G, A, M, Juvenile Arthritis Disease Activity Score-27 (JADAS27), and serum acute phase reactants (sAPR) were obtained in JIA. In the presence of allergic symptoms, skin prick (SPT) and pulmonary function tests (PFT) were performed.Despite similar allergy risk factors, the frequencies of asthma and allergic rhinitis were lower in JIA group (allThe frequencies of AD, asthma, and allergic rhinitis may decrease in Th1-mediated JIA subtypes although the coexistence does not appear to affect the severity of arthritis whereas allergic symptoms may resolve after immunosuppressive treatment. PFTs should be obtained periodically in JIA. JIA patients may have an underlying primary immunodeficiency (ID) or immunosuppressive drugs may cause secondary ID.KEY POINTSCompared to the population, the frequency of Th2-mediated allergic diseases is lower in oligoarthritis and RF-negative polyarthritis that are primarily driven by a Th1 activity.The coexistence of allergic diseases in juvenile idiopathic arthritis does not affect the severity of arthritis.Pulmonary function tests can be thought to be obtained periodically in juvenile idiopathic arthritis.Immunological workup should be considered in atypically or severely presented patients with juvenile idiopathic arthritis before the initiation of immunosuppressive therapy to differentiate primary and secondary immunodeficiency.

Autoinflammatory diseases are characterized by recurrent fevers and clinical findings of impaired natural immunity and can involve various organ systems. The concept of autoinflammatory disease emerged after the definition of familial Mediterranean fever and tumor necrosis factor receptor-associated periodic syndrome. This new disease group was considered to differ from the standard concept of autoimmune diseases, which is relatively better known in terms of basic features, such as defects in innate immunity and the absence of antibodies. A better understanding has been achieved regarding the genetic and pathogenetic mechanisms of this relatively new disease group over the past 20 years since they were first diagnosed, which have led to some changes in the concept of autoinflammatory diseases. The recent definition classifies autoinflammatory disease to be a wide range of diseases with different clinical features, mainly accompanied by changes in innate immune and rarely in humoral immunity. The spectrum of autoinflammatory diseases is rapidly expanding owing to recent developments in molecular sciences and genetics. This review article discusses the clinical features, classification criteria, treatment options, and long-term prognosis of periodic fever, aphthous stomatitis, pharyngitis, adenitis syndrome, and other common autoinflammatory diseases in the light of current literature.

Objectives Clinical and laboratory investigations have revealed that Epstein–Barr virus (EBV) is involved in altered immunological response of systemic lupus erythematosus (SLE). Higher seroprevalence rates of anti-EBV antibodies and increased viral load are demonstrated in adult SLE patients. The prevalence of BK polyomavirus (BKV) reactivation is also suggested to be higher in SLE. Herein, we aimed to evaluate the immune response of children with SLE to EBV antigens in addition to EBV and BKV DNA. We also tried to evaluate whether these serological results differ from another connective tissue disease – juvenile systemic sclerosis (jSS) – and healthy individuals. Methods Serum levels of EBV early antigen diffuse (EA-D) IgG, EBV nuclear antigen-1 IgG, EBV viral capsid antigen (VCA), cytomegalovirus (CMV) IgG, EBV DNA, CMV DNA and urinary BKV DNA were evaluated in healthy controls and in patients with a diagnosis of juvenile SLE (jSLE) and jSS. Results A total of 70 jSLE patients, 14 jSS patients and 44 sex-matched healthy individuals were involved in the study. EBV VCA was positive in 84.2% of jSLE patients, 85.7% of jSS patients and 36.3% of healthy controls. EBV EA-D IgG positivity was significantly higher in jSLE patients compared to jSS patients and healthy controls (20% vs. 7.1% and 0%, p = 0.005). EBV VCA positivity was associated with malar rash and immunological disorder, but there was no statistical significance in other antibody positivity in terms of clinical and haemogram findings and autoantibody positivity. CMV DNA positivity was present in only 2.8% of jSLE patients. None of the jSS patients or the healthy controls had CMV DNA positivity. EBV DNA and BKV DNA were also negative in all three groups. Conclusion The results of our study assume a relationship between SLE and EBV, but we could not demonstrate an association between CMV and BKV. The negative DNA results in contrast to serological positivity can be interpreted as an altered and impaired immune system and increased viral susceptibility. These results suggest that EBV contributes to disease continuity, even if it does not directly cause development.

As it is known, we are all in a pandemic situation due to a novel coronavirus, officially named “Severe Acute Respiratory Syndrome Coronavirus 2” and the disease caused by the virus named “Coronavirus disease-2019”. The virus seems to has propensity to infect older male individuals with underlying disease. The clinical features were on a large scale that varies from being an asymptomatic carrier to acute respiratory distress syndrome and multiorgan dysfunction. Fever, dry cough and fatigue are the most common symptoms. Not only, the disease seems to be rare and have a milder course in pediatric age but also respiratory failure, multiorgan dysfunction, and death are extremely rare. Although several comorbidities such as hypertension, diabetes and cardiovascular diseases are defined as a risk factor for developing the acute respiratory syndrome and need for intensive care; immune-compromised situations such as rheumatic disease which require immunosuppressive treatment strikingly are not found to be a risk factor for more severe disease course. However, there is a lack of data regarding the effects of “Coronavirus disease-2019” on pediatric patients with rheumatic diseases. Additionally, there are three controversial circumstances that patients with rheumatic diseases are believed to be more likely to have viral infections like “Severe Acute Respiratory Syndrome Coronavirus 2”, on the other hand, antirheumatic drugs may have a protective and therapeutic role in Coronavirus disease-2019 and children are more unlikely to have serious disease course. Therefore, we aimed to have a contributor role for explaining this conundrum and present a bird’s eye view regarding this equivocal issue in this review. In December 2019, a cluster of acute viral pneumoniae cases with unknown origin emerged in Wuhan, Hubei province, China (1). Most of the cases had a common exposure to the Huanan wholesale seafood market (2). Several days later, causative viral agent was analyzed with deep sequencing and indicated as a novel coronavirus, officially named 2019 novel coronavirus (2019 nCoV) (3). Coronavirus Study Group (CSG) of the International Commission on Virus Classification named this novel coronavirus “Severe Acute Respiratory syndrome Coronavirus 2 (SARS-CoV-2)” on February 11, 2020 and on the same day, the World Health Organization (WHO) named the disease caused by SARS-CoV-2, “Coronavirus disease-2019 (COVID-19)” (4). In a couple of weeks, severe COVID-19 cases were all over the world, and on the basis of disease severity and spread, finally WHO characterized the COVID-19 situation as a pandemic on March 11th, 2020 (5). In the past two decades, addition to this current pandemic, we experienced two different coronavirus outbreaks, and previous two were named “Severe Acute Respiratory Syndrome Coronavirus” (SARS-CoV) and “Middle East Respiratory Syndrome Coronavirus” (MERS-CoV) (6). Bats are known to be reservoir hosts for SARS-CoV and MERS-CoV (7). Given the findings of genomic analyze of SARS-CoV-2, bats are assumed to be origin of also COVID-19 pandemic (8). Although intermediary animals between bats and humans are uncertain, pangolin and snakes seem to be leading suspects (2).

Mercury is the only metal that remains in liquid form at the room temperature. It is a very toxic metal and even short-term exposure can lead to poisoning. Mercury intoxication can affect many systems such as skin, cardiovascular, genitourinary, central and peripheral nervous, respiratory, and musculoskeletal system. Consequently, the diagnosis of mercury intoxication can be challenging due to its non-specific and multisystemic presentation. Herein, we report five pediatric cases with mercury intoxication from two families that were initially misdiagnosed as rheumatic disorders. We also performed a literature review about pediatric cases with mercury intoxication to investigate the clinical findings in children, the source of intoxication, and the current treatment preferences. As in our cases, reported patients were previously misdiagnosed as various infectious and/or rheumatic diseases before the diagnosis of mercury intoxication was established. A delay in diagnosis and treatment can cause serious morbidities and even mortality. We report this case series to emphasize the multisystemic presentation of mercury intoxication, and to remind and provide clues for physicians to recognize this rare toxicologic syndrome.

Although Familial Mediterranean Fever (FMF) progresses with attacks, its subclinical inflammation may continue in attack-free periods. To date, increased inflammatory cytokines have been reported in many psychiatric diseases. In this study, we aimed to evaluate the psychological symptoms, especially inattention/hyperactivity, in patients with FMF. The study included 272 children and adolescents with FMF and 250 healthy peers as a control group. The Strengths and Difficulties Questionnaire-Parent Form was used to assess emotion, behavior and peer related problems, as well as inattention/hyperactivity and prosocial behavior in participants. The age and gender of the children were similar across groups. The emotional and behavioral problem subscale scores of patients with FMF were significantly higher than those of healthy controls. The inattention/hyperactivity scores of patients with FMF were also significantly higher than those of the control group (3.99 ± 2.34 vs 2.93 ± 2.26, p 0.001). When patients with FMF were compared according to the presence of attacks in the last year, presence of exertional leg pain, no differences were found in terms of inattention/hyperactivity scores. However, patients whose FMF symptoms started before 6 years of age had significantly higher inattention/hyperactivity scores than those whose symptoms begun after 6 years of age. This research demonstrated that FMF patients had increased inattention/hyperactivity, which was unaffected by FMF-related variables, except for age of onset. The FMF-inattention/hyperactivity relationship may be due to a common etiology in which proinflammatory cytokines play a role.

OBJECTIVE: Utilizing data obtained from a prospective, international, juvenile systemic sclerosis (SSc) cohort, the present study was undertaken to determine if pulmonary screening with forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLco) is sufficient to assess the presence of interstitial lung disease (ILD) in comparison to high-resolution computed tomography (HRCT) in juvenile SSc. METHODS: The juvenile SSc cohort database was queried for patients enrolled from January 2008 to January 2020 with recorded pulmonary function tests (PFTs) parameters and HRCT to determine the discriminatory properties of PFT parameters, FVC, and DLco in detecting ILD. RESULTS: Eighty-six juvenile SSc patients had both computed tomography imaging and FVC values for direct comparison. Using findings on HRCT as the standard measure of ILD presence, the sensitivity of FVC in detecting ILD in juvenile SSc was only 40%, the specificity was 77%, and area under the curve (AUC) was 0.58. Fifty-eight juvenile SSc patients had both CT imaging and DLco values for comparison. The sensitivity of DLco in detecting ILD was 76%, the specificity was 70%, and AUC was 0.73. CONCLUSION: The performance of PFTs in juvenile SSc to detect underlying ILD was quite limited. Specifically, the FVC, which is one of the main clinical parameters in adult SSc to detect and monitor ILD, would miss ~60% of children who had ILD changes on their accompanying HRCT. The DLco was more sensitive in detecting potential abnormalities on HRCT, but with less specificity than the FVC. These results support the use of HRCT in tandem with PFTs for the screening of ILD in juvenile SSc.

The purpose of this study is to share our experience about clinical findings, natural course, and treatment response rates of a large cohort of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome.Medical records of patients who were diagnosed with PFAPA syndrome between January 2010 and May 2021 at Istanbul University-Cerrahpasa Cerrahpasa Medical Faculty pediatric rheumatology department were reviewed retrospectively.A total of 607 patients (females: 277, males: 330) with PFAPA syndrome were included. The median duration of episodes was 3 (1-15; interquartile range (IQR) 3-5) days, and the median interval between episodes was 20 days (5-120; IQR 15-30). The median age at the last attack and median disease duration were 66 (24-168; IQR 48-84) months and 40 (4-132; IQR 27.5-60) months, respectively. Fever (100%) was the most common clinical finding, followed by pharyngitis/exudative tonsillitis in 594 (97.9%), aphthous stomatitis in 308 (50.7%), cervical lymphadenopathy in 278 (45.8%), abdominal pain in 249 (41%), and arthralgia in 228 (37.6%) of the patients. Among the clinical findings, there was no statistical difference according to gender, except for cervical lymphadenitis being higher in males (P.001). Of the patients who were given steroids during attacks, 94.6% were responsive. Colchicine was effective in 93 (63.7%) patients. The disease episodes ceased in 313 (95.4%) of patients who had tonsillectomy/adenoidectomy.Clinicians should be alert for additional symptoms such as abdominal pain, arthralgia, and headache apart from the cardinal signs. Although tonsillectomy is highly effective, its use is controversial. Colchicine may be a good alternative for prophylaxis.

Einleitung: Schlafdeprivation bei kritisch Erkrankten auf der Intensivstation (ICU) ist häufig auf die Umgebung der Intensivstation zurückzuführen. Dabei ist ein erholsamer Schlaf für die Genesung dieser Patient*innen wesentlich. Nicht-pharmakologische Interventionen sind nicht invasiv, gut verträglich und leicht umsetzbar und können als Alternative zu pharmakologischen Interventionen eingesetzt werden, um die Schlafqualität zu verbessern und somit Schlafdeprivation bei kritisch Erkrankten zu vermeiden. Methodik: Die Forschungsfragen wurden mittels einer systematischen Literaturrecherche in vier Online-Datenbanken beantwortet. Nach der Bewertung der Studien sowie unter Berücksichtigung der Ein- und Ausschlusskriterien wurden insgesamt 15 Studien zur Beantwortung der Forschungsfragen für diese Bachelorarbeit herangezogen. Ergebnisse: Die Ergebnisse der Studien zeigen deutlich, dass der Geräuschpegel, die Beleuchtung, die pflegerischen Tätigkeiten sowie das Angstgefühl und die Sorgen, um das eigene Leben die Schlafqualität der Patient*innen beeinflussen. Der Geräuschpegel kann durch die Verwendung von Ohrstöpsel, Musik sowie durch Mehrkomponentenbündel reduziert werden. Um das künstliche Licht zu maskieren, können Augenmasken eingesetzt werden. Zur Entspannung hat sich der Einsatz von Aromatherapie als wirksam erwiesen. Schlussfolgerung: Die Umgebungsfaktoren, die den Schlaf von kritisch Erkrankten auf der Intensivstation beeinflussen sind unterschiedlich. Daher ist es unerlässlich, dass diese vom gehobenen Dienst der Gesundheits- und Krankenpflege erkannt und nicht pharmakologische Interventionen gesetzt werden, um den Schlaf zu verbessern und Auswirkungen auf Herz-Kreislaufsystem, Immunsystem und die Entwicklung von Delirium zu reduzieren. Es bedarf weitere Forschung, um langfristige Folgeschäden zu untersuchen. Schlüsselbegriffe: Schlafdeprivation, kritisch Erkrankte, Intensivstation, nicht-pharmakologische Interventionen Introduction: Sleep deprivation in critically ill patients in the intensive care unit is often due to the environment of the intensive care unit. A restful sleep is important for the recovery of these patients. Non-pharmacological interventions form a basis for non-invasive, well-tolerated and usually easy-to-implement methods that can be used as an alternative to pharmacological interventions. In order to avoid sleep deprivation, it is necessary to improve the sleep quality of critically ill patients in the intensive care unit. Methodology: The research questions were answered by means of a systematic literature search in four online databases. After evaluating the studies and taking into account the inclusion and exclusion criteria, a total of 15 studies were used to answer the research questions for this bachelor thesis. Results: The results of the study clearly show that the noise level, the lighting, the nursing activities as well as the feeling of anxiety and worries about one's own life influence the sleep quality of the patients. Noise levels can be reduced by using earplugs, music as well as multi-component bundles. To mask the artificial light, eye masks can be used. For relaxation, the use of aromatherapy has proven to be effective. Conclusion: The environmental factors that affect the sleep of critically ill patients in the intensive care unit are different. Therefore, it is imperative that these are recognized by nurses and set non pharmacological interventions to improve sleep and reduce the effects on the cardiovascular system, immune system and delirium risk. Keywords: Sleep deprivation, critically ill patients, intensive care unit, non-pharmacological interventions

Supplemental material, sj-pdf-1-jso-10.1177_23971983221143244 for Gender differences in juvenile systemic sclerosis patients: Results from the international juvenile scleroderma inception cohort by Ivan Foeldvari, Jens Klotsche, Ozgur Kasapcopur, Amra Adrovic, Maria Teresa Terreri, Ana Paula Sakamoto, Valda Stanevicha, Jordi Anton, Brian M Feldman, Flavio Sztajnbok, Raju Khubchandani, Ekaterina Alexeeva, Maria Katsicas, Sujata Sawhney, Vanessa Smith, Simone Appenzeller, Tadej Avcin, Mikhail Kostik, Thomas Lehman, Edoardo Marrani, Dieneke Schonenberg-Meinema, Walter-Alberto Sifuentes-Giraldo, Natalia Vasquez-Canizares, Mahesh Janarthanan, Monika Moll, Dana Nemcova, Anjali Patwardhan, Maria Jose Santos, Cristina Battagliotti, Lillemor Berntson, Blanca Bica, Jürgen Brunner, Rolando Cimaz, Patricia Costa-Reis, Despina Eleftheriou, Liora Harel, Gerd Horneff, Sindhu R Johnson, Daniela Kaiser, Tilmann Kallinich, Dragana Lazarevic, Kirsten Minden, Susan Nielsen, Farzana Nuruzzaman, Siri Opsahl Hetlevik, Yosef Uziel, Nicola Helmus and Kathryn S Torok in Journal of Scleroderma and Related Disorders

Considering the concerns regarding the coronavirus disease-2019 (COVID-19) vaccine safety among pediatric patients with inflammatory rheumatic diseases (IRD) due to a lack of data, an urgent need for studies evaluating safety profiles of vaccines emerged.Among participants vaccinated by CoronaVac inactive SARS-CoV-2 or BNT162b2 messenger RNA (mRNA) COVID-19 (Pfizer-BioNTech) vaccine, healthy children under 18 and patients under 21 with an at least 1-year follow-up period in our department for a childhood-onset rheumatic disease were included into this cross-sectional study.Overall, 246 subjects (141 [57.3%] females) (biologic group: 43, non-biologic group: 180, healthy control group: 23) were eligible for the study. The median age was 15.34 (12.02-20.92) years. The most common adverse events were fatigue (n = 68, 27.6%), headache (n = 44, 17.9%), myalgia (n = 38, 15.4%), arthralgia (n = 38, 15.4%), and fever (n = 35, 14.2%). Only 3 subjects (2 patients with familial Mediterranean fever, and one healthy child) were considered to experienced serious adverse events, since they required hospitalization. Local reactions were seen in 20 (8.13%), and 27 patients (12.1%) had disease flares within 1 month after the vaccines. Although it was significantly higher in those who received the BNT162b2 mRNA vaccine (P .001), there was no significant relationship between adverse event frequency and age, gender, the existing diseases, ongoing treatment regimens and pre-vaccination COVID-19 histories.Although immunogenicity studies for efficacy of the vaccines and long-term follow-up studies for adverse events monitoring are required, our study indicates an acceptable safety profile of COVID-19 vaccines and encourages children with IRD to be vaccinated.
