Early experience of COVID-19 vaccine-related adverse events among adolescents and young adults with rheumatic diseases: A single-center study

Objective 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. Methods 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. Results 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. Conclusion 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

An overview of the relationship between juvenile idiopathic arthritis and potential environmental risk factors: Do early childhood habits or habitat play a role in the affair?

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

Genetic screening of early-onset patients with systemic lupus erythematosus by a targeted next-generation sequencing gene panel

Objective In 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) disease. Methods A total of 48 SLE patients (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. Results Among 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). Conclusion We 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

An evaluation of sleep habits and childhood-onset systemic lupus erythematosus

Objectives Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, known for its heterogeneous clinical presentation. Although it is rarer in children, a more severe clinical course can be seen than in adults. It is known that sleep has physiological and developmental importance in children, and there are many studies on sleep quality in adult SLE patients. The aims of this study are to evaluate the sleep habits of children and adolescents with SLE and to compare them with their healthy peers

The efficacy of a single-dose anakinra injection during disease attack in pediatric familial Mediterranean fever

The aim of this retrospective study is to evaluate the efficacy of a single-dose anakinra during familial Mediterranean fever (FMF) attacks and its effect on the duration, severity, and frequency of attacks. The patients with FMF who had disease episode and received a single-dose anakinra during disease episode between December 2020 and May 2022 were included. Demographic characteristics, MEFV gene variants detected, concomitant medical conditions, demographics of recent and previous episodes, laboratory findings and length of hospital stay were recorded. A retrospective analysis of medical records revealed 79 attacks from 68 patients who met inclusion criteria. The patients had a median age of 13 (2.5-25) years. All patients reported that the average duration of their previous episodes lasted longer than 24 h. When the recovery time of attacks after subcutaneous anakinra application at the disease attack was examined, it was observed that 4 attacks (5.1%) ended in 10 min; 10 attacks (12.7%) in 10-30 min; 29 attacks (36.7%) in 30-60 min; 28 attacks (35.4%) in 1-4 h; 4 attacks (5.1%) in 24 h; and 4 attacks (5.1%) ended in more than 24 h. There was no patient who did not recover from their attack after a single dose of anakinra. Although the efficacy of a single-dose anakinra administration during FMF attacks in children needs to be confirmed by prospective studies, our results suggest that use of a single-dose anakinra during FMF attacks is effective in reduction of severity and duration of disease attacks

Non-Rheumatic Chronic Comorbidities in Children with Juvenile Idiopathic Arthritis

Objective: Juvenile idiopathic arthritis is a heterogeneous group of disorders and is the most common rheumatic condition in childhood. There are scarce data regarding all comorbidities in juvenile idiopathic arthritis patients. Materials and Methods: We aimed to identify the non-rheumatic comorbidities in our juvenile idiopathic arthritis patients. Data were obtained cross-sectionally from the medical records and the face-to-face interviews for 6 consecutive months. Those with more than 1 rheumatic disease were excluded, and conditions that were highly related to the disease, such as uveitis, were not taken into account. Results: The study included 459 patients with female dominance (62.1%, n = 285). The median age of the patients was 12.87 (1.53-20.95) years. One hundred fifty patients (32.7%) had at least 1 comorbidity (5 patients had 3 comorbidities, and 24 patients had 2 comorbidities). The most common 3 non-rheumatic accompanying medical conditions in our patients were allergic rhinitis (n = 37, 8.1%), attention-deficit hyperactivity disorder (n = 35, 7.6%), and atopic dermatitis (n = 28, 6.1%). None of our patients with systemic JIA had any autoimmune disease. All the patients with primary immune deficiencies had anti-nuclear antibody positivity. Conclusion: Almost one-third of our patients had at least one comorbidity. This finding might be very helpful to us in planning our multi-disciplinary approach to our patients

Comparisons of Clinical Features and Outcomes of COVID-19 between Patients with Pediatric Onset Inflammatory Rheumatic Diseases and Healthy Children

(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
