RESUMO
OBJECTIVE: This study aimed to provide a comprehensive overview of the clinical features, laboratory and screening results, treatment options, and outcomes of patients with type 1 interferonopathy. Our secondary goal was to identify the predictors of long-term morbidities or fatalities. METHODS: We included children with genetically confirmed type 1 interferonopathies, with a follow-up duration of > 1 year. Data were obtained retrospectively from medical records. RESULTS: Of the 40 eligible patients for the study, 52.5% were female, with a median age of disease onset of 1.5 years (0.1-13.2). They were diagnosed at an average age of 6.8 ± 4.6 years. Aicardi-Goutières Syndrome was the most common diagnosis (n=15; 37.5%). The central nervous system was the most frequently affected system (n=27; 67.5%). Janus kinase inhibitors were administered to 17 (42.5%) patients. Twenty-five patients (62.5%) developed at least one permanent morbidity or died during follow-up; thus, they were included in the poor-outcome group. While younger age at disease onset, intracranial calcification (ICC), and lack of chilblains and elevated acute phase reactants (APRs) were significant in univariate logistic regression analysis, only ICC on MRI at admission (aOR, 19.69; 95% C.I.: 1.08-359.05, p=0.04) was found to be a significant predictor of poor outcomes in multivariate logistic regression analysis. CONCLUSION: For the first time, we evaluated the predictors of poor outcomes in patients with type 1 interferonopathy with a broad spectrum of subtypes. Furthermore, our study's unique patient characteristics can provide valuable insights into these extremely rare conditions.
RESUMO
Familial Mediterranean Fever (FMF) is the most common monogenic autoinflammatory disease worldwide. In this retrospective cohort study, we aimed to assess the effects of various MEFV genotypes on the clinical characteristics of the patients, with a special focus on the joint involvement. In total, 782 patients with FMF were categorized into 3 groups according to the MEFV mutation; Group 1: Patients homozygous for M694V; Group 2: Patients carrying other pathogenic MEFV variants in exon 10 in homozygous or compound heterozygous states; and Group 3: FMF patients with other variants or without mutations. Clinical and demographic findings were compared between groups. Among the 782 FMF patients, total frequency of arthritis was 237 (30.3%): 207 (26.4%) were acute monoarthritis and 67 (8.5%) were chronic arthritis. Both the frequency of arthritis (acute and/or chronic) (40.4% vs. 24.8% vs. 26.7%; p:0.001) and acute monoarthritis (35.4% vs. 20% vs. 23.7%; p:0.001) were significantly higher in Group 1 than in the other groups. FMF patients with chronic arthritis showed a distinct juvenile idiopathic arthritis (JIA) distribution pattern with a more frequent enthesitis-related arthritis (ERA) subtype (43.2%). HLA-B27 was positive in 24% of the ERA patients.Conclusion: Homozygous M694V mutation is associated with a more frequent and longer acute monoarthritis comparing to other MEFV genotypes. In addition, the risk of chronic arthritis seems not related to the MEFV mutations. However, FMF patients with chronic arthritis show a distinct ILAR JIA distribution pattern with a more frequent ERA and undifferentiated arthritis subtype. What is known: ⢠Homozygous M694V mutation is associated with a more frequent and longer acute monoarthritis What is new: ⢠FMF patients with chronic arthritis show a distinct ILAR JIA distribution pattern with a more frequent ERA subtype ⢠ERA patients with negative HLA-B27 antigen should also be assessed for polyserositis episodes of FMF, especially in countries with high FMF carrier frequency.
RESUMO
OBJECTIVE: Increased frequency of autoimmune thyroid disease, particularly Hashimoto's thyroiditis (HT) was reported several studies in the literature, in individuals with childhood-onset systemic lupus erythematosus (cSLE). Our study aimed to investigate the prevalence and contributing factors of thyroid dysfunction and HT among cSLE patients. METHODS: Thyroid function tests were obtained cross-sectionally from cSLE patients. Demographic, clinical, and laboratory characteristics and activity scores were collected from medical records. Patients diagnosed with cSLE were compared to the healthy control group for the frequency of thyroid dysfunction. The Mann-Whitney U, independent samples t test, and the Chi-square or Fisher's exact test were used to compare study groups. A p-value below 0.05 was considered statistically significant. RESULTS: Out of 73 cSLE patients, 14 (19.1%) had subclinical hypothyroidism, 9 (12.3%) had clinical hypothyroidism, 12 (16.4%) were diagnosed with HT, and 12 (16.4%) had a family history of HT. Thyroid USG was performed in 5 euthyroid patients and 1 borderline subclinical hypothyroid patient with positive thyroid autoantibody and reported as diffuse heterogeneous echogenicity enlargement in the thyroid gland. There were no significant differences in clinical and laboratory data or medication used between the groups with and without HT; however, patients with HT had a higher frequency of clinical hypothyroidism and family history of HT. Cumulative prednisolone dose was significantly lower in patients diagnosed with HT. The frequency of HT was considerably higher in patients with cSLE compared to the healthy control group. CONCLUSION: The results demonstrate an increased incidence of HT in cSLE patients, even if they are euthyroid, and recommend that cSLE patients be screened more frequently.
RESUMO
Artificial intelligence algorithms, with roots extending into the past but experiencing a resurgence and evolution in recent years due to their superiority over traditional methods and contributions to human capabilities, have begun to make their presence felt in the field of pediatric rheumatology. In the ever-evolving realm of pediatric rheumatology, there have been incremental advancements supported by artificial intelligence in understanding and stratifying diseases, developing biomarkers, refining visual analyses, and facilitating individualized treatment approaches. However, like in many other domains, these strides have yet to gain clinical applicability and validation, and ethical issues remain unresolved. Furthermore, mastering different and novel terminologies appears challenging for clinicians. This review aims to provide a comprehensive overview of the current literature, categorizing algorithms and their applications, thus offering a fresh perspective on the nascent relationship between pediatric rheumatology and artificial intelligence, highlighting both its advancements and constraints.
RESUMO
BACKGROUND: To demonstrate the long-term safety profile of canakinumab over a nine-year period by documenting adverse events in patients with various pediatric rheumatic diseases. RESEARCH DESIGN AND METHODS: This retrospective observational study was conducted at the Pediatric Rheumatology Department of Istanbul University Cerrahpasa between 2015 and 2023. The analysis concerned individuals who had been administered canakinumab treatment for at least six months. The exposure-adjusted event rates were calculated as adverse events per 100 patient days and were compared among three groups based on the cumulative canakinumab dose of <35 mg/kg, 35-70 mg/kg, and >70 mg/kg. RESULTS: Among 189 patients, the median exposure time to canakinumab was 2.9 (1.5-4.1) years, corresponding to 573.4 patient years. The median cumulative dose of canakinumab was 2205 (1312-3600) mg. The most common adverse event was upper respiratory tract infection (0.76), followed by urinary tract infection (0.02), pneumonia (0.009), latent tuberculosis (0.009) and lymphadenitis (0.004). A total of 55 serious adverse events (0.025) were reported, 12 (0.006) of which led to drug discontinuation. The event rate of macrophage activation syndrome and disease exacerbation was statistically higher in patients receiving <35 mg/kg cumulative canakinumab dose (p < 0.05). CONCLUSIONS: An increase in side effect was not observed with the increasing cumulative doses of canakinumab. Canakinumab demonstrated long-term safety with appropriate indication and monitoring.
RESUMO
Rituximab (RTX) is a chimeric monoclonal antibody that targets the CD20 antigen on B cells and is used in various autoimmune disorders. In this study, we aimed to measure the awareness of pediatric rheumatologists about the use of RTX through a survey. Between February and March 2023, a 42-question survey was sent via email to pediatric rheumatology specialists in Turkey. The participants were questioned for which diagnoses and system involvement they preferred to use RTX, which routine tests they performed, vaccination policy, and adverse events that occurred during or after infusion. Forty-one pediatric rheumatologists answered the survey. They prescribed RTX most frequently for systemic lupus erythematosus (87.8%) and ANCA-associated vasculitis (9.8%). Prior to the administration of RTX, 95% of clinicians checked renal and liver function tests, as well as immunoglobulin levels. The most frequently tested hepatitis markers before treatment were HBsAg and anti-HBs antibody (97.6%), while 85.4% of rheumatologists checked for anti-HCV. Clinicians (31.4%) reported that they postpone RTX infusion 2 weeks following an inactivated vaccine. Sixty-one percent of rheumatologists reported starting RTX treatment 1 month after live vaccines, while 26.8% waited 6 months. The most frequent adverse events were an allergic reaction during RTX infusion (65.9%), hypogammaglobulinemia (46.3%), and rash (36.6%). In the event of hypogammaglobulinemia after RTX treatment, physicians reported that they frequently (58.5%) continued RTX after intravenous immunoglobulin administration. CONCLUSIONS: RTX has become a common treatment option in pediatric rheumatology in recent years. Treatment management may vary between clinician such as vaccination and routine tests. WHAT IS KNOWN: ⢠During the course of rituximab therapy, clinicians should be attentive to specific considerations in pre-treatment, during administration, and in post-treatment patient monitoring. WHAT IS NEW: ⢠There are differences in practice among clinicians in the management of RTX therapy. These practice disparities have the potential to impact the optimal course of treatment. ⢠This study highlights that standardized guidelines are needed for RTX treatment in pediatric rheumatology, particularly for vaccination policies and routine tests.

BACKGROUND: Given the strong genetic background of familial Mediterranean fever (FMF), the frequently reported co-existing diseases in children with FMF should also be investigated in other family members. Therefore, we aimed to examine the medical conditions of first-degree relatives (FDRs) of our pediatric patients with FMF in the present study. METHODS: Chronic diseases of FDRs of pediatric 449 FMF, 147 juvenile idiopathic arthritis (JIA) patients and 93 healthy controls (HC) were questioned during their routine clinical visits for 9 consecutive months. RESULTS: A total of 1975 FDRs of 449 FMF, 690 FDRs of 147 JIA patients, and 406 FDRs of 93 HC were included into the study. The most common medical conditions were non-atopic asthma (n=71, 3.6%), type 2 DM (n=14, 2%), and tonsillectomy history (n=12, 2.95%) in the FMF, JIA, and HC groups, respectively. Atopic diseases (FMF vs. JIA: p=0.013; FMF vs. HC: p=0.014), rheumatic diseases (FMF vs. JIA: p=0.030; FMF vs. HC: p=0.017), and surgical histories (FMF vs. JIA: p<0.01; FMF vs. HC: p=0.026), including adenoidectomy, tonsillectomy, and appendectomy, were significantly more common in the FMF group than in other groups. CONCLUSIONS: Our novel findings may contribute to understanding the hereditary burden of co-existing diseases in children with FMF and encourage further studies involving genetic screenings.

BACKGROUND: Nailfold videocapillaroscopy (NVC) is the primary diagnostic tool for the assessment of microcirculation in the pediatric population. OBJECTIVE: To define and standardize age-specific normal NVC patterns in healthy children and adolescents. METHODS: A cross-sectional observational multicentric study was conducted in 564 participants aged 5-17 years. Dino-Lite CapillaryScope 200 Pro Model MEDL4N Pro was performed at 200× magnification. Quantitative and qualitative NVC parameters were analyzed separately for each age group and divided into 4 groups based on age categories. RESULTS: Of the 564 healthy participants, 54.9% were female. A total of 1184 images and 3384 capillaries were analysed. Positive correlations were observed between age and capillary density (p < 0.001, R = 0.450, CI95% 0.398-0.503). There was also a positive correlation between age and arterial/venous, loop diameter and capillary length, whereas there was a weak negative correlation between intercapillary distance. However, no correlation was found between age and capillary width. In addition, capillary density was significantly lower in 5-7 age group compared to the other patient groups. Arterial limb diameter was lower in 5-7 age group, while venous limb diameter was significantly wider in 15-17 age group compared to the other patient groups. Dilated capillaries (8.7%), capillary tortuosity (14.4%), crossed capillaries (43.1%), micro-haemorrhages (2.7%), avascular area (4.8%) were present in all age groups. Excellent intra- and interobserver ICC values were obtained for all parameters. CONCLUSION: These findings hold potential significance for future studies, aiding in the analysis and differentiation of children suspected of rheumatological diseases with potential microangiopathy.
RESUMO
Early detection of cardiac involvement in Juvenile Dermatomyositis (JDM) is difficult due to the absence of clinical signs and symptoms, with systolic dysfunction often emerging in late stages and associated with a poor prognosis. This study aimed to employ two-dimensional speckle-tracking echocardiography (STE) for subclinical assessment of left ventricular (LV) systolic failure in JDM and explore potential associations between impaired LV systolic function (LV-GLS) and disease activity. A prospective study enrolled 20 healthy volunteers and 26 JDM patients (< 18 years old) without cardiac symptoms. Clinical data were collected from medical records, and echocardiograms were conducted by a pediatric cardiologist. Our study cohort demonstrated similar age to controls (13.5 ± .6 vs. 13.8 ± 4.7; p = 0.465). Median illness duration at echocardiography was 5 (1.5-17.5) years, and conventional echocardiography indicated normal LV ejection fraction (> 55%) in all participants. However, STE revealed lowered LV GLS in JDM patients (- 22.2 ± 4.1% vs. - 26.5 ± 5.3% p = 0.022). Pulse steroid users displayed lower GLS average values compared to non-users (ß = 4.99, 95% CI 1.34-8.64, p = 0.009). Negative correlations existed between LV-GLS and age at diagnosis (r = - 0.499; p = 0.011), diastolic parameters (E/E' ratio) and age at diagnosis (r = - 0.469; p = 0.018), as well as RV global strain and age at diagnosis (r = - 0.443; p = 0.024). Employing STE in JDM patients facilitated the identification of preclinical cardiac dysfunction. Given JDM patients' younger age, early myocardial damage detection through STE may impact treatment decisions and long-term cardiovascular prognosis.

OBJECTIVES: Biological drugs are one of the most effective treatment methods for systemic juvenile idiopathic arthritis (SJIA) and can significantly prevent morbidity and mortality. This study aimed to evaluate the efficacy and safety of biologics in patients with SJIA and provide real-life data that might help improve the outcomes. METHODS: TURSIS was a retrospective multicentre study carried out in patients with SJIA for whom a biological treatment had been initiated between 1st March 2013 and 30th December 2018. Data include patients' characteristics, laboratory-clinical results, outcomes, and safety-related variables. The 24-month follow-up data of the patients and the efficacy and safety of biological drugs were evaluated. RESULTS: 147 patients were enrolled. The clinical course of the disease was as follows; it was monocyclic in 38.1%, polycyclic in 49%, and persistent in 12.9% of patients. First-choice biologics were interleukin (IL)-1 blockers in the majority of patients (56.5%), followed by the anti-IL-6 (25.2%) and anti-TNF-alpha drugs (18.4%). Anakinra was the most preferred biologic agent in patients with macrophage activation syndrome (MAS), and tocilizumab was used more frequently in patients with persistent type (p=0.000 and p=0.003). The most frequent switch rate was seen in patients receiving anakinra (n=40/68, 58.8%), and it was most frequently switched to canakinumab (n=32/40, 80%). Better physician's global assessment scores were achieved in patients treated with anakinra in Month 3, compared to other treatments (p=0.04). CONCLUSIONS: The results of our study support the efficacy of biological drugs in particular anti-IL-1 and anti-IL-6 drugs, in the treatment of SJIA. These treatments resulted in improvement in activity of disease and provide a considerable decrease in the frequency of MAS.

BACKGROUND/OBJECTIVES: The aim of the study is to assess the effect of juvenile idiopathic arthritis (JIA) and biologic disease-modifying anti-rheumatic drugs (bDMARDs) on ovarian reserve in children. MATERIALS AND METHODS: A cross-sectional study was performed from March 2021 to March 2022 and included 81 patients with JIA and 49 healthy children. Serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol levels were analyzed using electrochemiluminescence methods. RESULTS: The mean of current age (13.5 ± 3.2 vs. 14.4 ± 2.4 years), height standard deviation score (SDS) (- 0.35 ± 1.18 vs. - 0.44 ± 0.94), body mass index SDS (0.12 ± 1.33 vs. 0.25 ± 1.28), and the median weight SDS (- 0.13 (- 2.27-3.23) vs. - 0.52 (- 3.4-3.3)) were similar in JIA patients and controls (p > 0.05). Patients with JIA were divided into two groups according to their treatment regimens: treated with methotrexate (MTX) (biologic naive) (n = 32) and treated with MTX plus bDMARDs (n = 49). No significant differences were detected between the 3 groups regarding menarche age, menstrual cycle length, and flow duration (for all p > 0.05). The median serum concentration of AMH was 2.94 (1.12-7.88) ng/ml in the control group, 3.02 (0.36-8.54) ng/ml in the biologic naïve group, and 3.01 (0.99-8.26) ng/ml in the MTX plus bDMARD group. There were no significant differences between 3 groups according to serum AMH, FSH, LH, and estradiol levels (p > 0.05). CONCLUSION: Biologic DMARDs are reassuring in terms of ovarian reserve in girls with JIA and demonstrate that AMH is unaffected by treatment. Prospective studies with larger sample sizes are needed to confirm our findings and to evaluate the impact on the future fertility of patients. Key Points ⢠Although biologic disease-modifying anti-rheumatic drugs (bDMARDs) are being game-changing treatment options in juvenile idiopathic arthritis, their effect on fertility and ovarian reserve is one of the most discussed issues. ⢠In addition to treatment used, autoimmune diseases might also have a negative effect on fertility. ⢠In this cross-sectional study, we found that anti-Mullerian hormone level of patients who were on bDMARDs, patients who were on methotrexate, and healthy controls were similar. ⢠Our results suggest that bDMARDs are reassuring in terms of ovarian reserve in girls with JIA and demonstrate that AMH is unaffected by treatment.

BACKGROUND: The aim of our study was to evaluate the long-term impacts of Kawasaki disease on our patients regarding coronary involvement demographic characteristics, treatment regimens, and clinical course. METHODS: Our study included 104 patients diagnosed and hospitalized with Kawasaki disease in our center, from January 2004 to January 2019. In our study, patients were divided into three groups according to coronary artery involvement. Patients in group 1 had no echocardiographic findings, while the ones in group 2 had coronary artery dilatation and ones in group 3 had coronary artery aneurysm (CAA). RESULTS: Among 104 patients, the median age was 9.15 (3.0-22.0) years, and 61 of the patients were male while 43 of the patients were female. With a wide range of 1.50-16.50 years of follow-up time, the median diagnosis age of our patients was 31 months (3.0-164.0). Fever duration (median day 10 (5-21), p = 0.025) was statistically significantly higher in group 3. Blood C-reactive protein (CRP) levels, white blood cell (WBC) counts, and neutrophil counts were significantly higher in group 3. There was a statistically significant difference between patients in group 3 and group 2 in which the lowest strain deformation values were in the patients of group 3. In contrast to group 1, the time for initiation of IVIG therapy is significantly prolonged both in group 2 (median: 9.5 days, p = 0.028) and group 3 (median: 10 days, p = 0.036). DISCUSSION: In our study, serum CRP levels, WBC count, and neutrophil count were higher in patients with coronary artery abnormalities, in agreement with the previous studies. In the light of our results, we consider that the most important determining factor for the development of coronary artery aneurysm is the time of intravenous immunoglobulin (IVIG) administration.

OBJECTIVE: Mercury poisoning is a condition with multiple-organ dysfunction that has effects on the central nervous system, gastrointestinal system, cardiovascular system, skin, lungs, and kidneys. It can be fatal or may result in sequelae such as neurological disturbances, if treated late or left untreated. The endocrinological effects of mercury exposure are not well-known. We aimed to evaluate patients with mercury poisoning. MATERIALS AND METHODS: A total of 6 cases of mercury poisoning from 3 families were included in the study. Clinical, laboratory, and follow-up data were recorded. RESULTS: Thyroid dysfunction was presented as high thyroid hormones and normal thyrotropin level (unsuppressed) in 5 cases (83.3%). On the other hand, pheochromocytoma-like syndrome was detected in 5 cases (83.3%) with hypertension. The 4 cases were the first to use methimazole for mercury poisoning due to tachycardia and hypertension despite antihypertensive treatment due to catecholamine excess and thyroid dysfunction. Hyponatremia was detected in 3 cases (50%). CONCLUSION: Mercury poisoning is difficult to diagnose because it is rare and presents with nonspecific physical and laboratory findings. Early diagnosis and providing appropriate treatment are essential in order to prevent sequelae. Mercury poisoning should be considered in patients with unexplained hypertension and tachycardia suggesting the involvement of thyroid hormones and catecholamines.
RESUMO
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.
RESUMO
Objectives: This study aimed to explore the influence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic among patients with juvenile systemic sclerosis (JSS). Patients and methods: Twenty-seven patients (22 females, 5 males; mean age: 20 years; range, 17 to 22 years) diagnosed with JSS and followed up at the department of pediatric rheumatology were included in the cross-sectional study. A web-based survey was performed by focusing on patients' complaints, accessibility to health care, and compliance with routine treatment from January 1, 2021, to January 10, 2021. Results: Five (18.5%) patients had deterioration of the disease, while six (22.2%) patients reported irregular usage of their routine scleroderma treatment during the last six months. Nine (33.3%) patients had missed their routine clinic control since the proclamation of the SARS-CoV-2 pandemic. Seven (25.9%) patients had household contact with coronavirus disease 2019 (COVID-19). Four (14.8%) patients were diagnosed with COVID-19, and only one (3.7%) was hospitalized. Nine patients were under biological treatment (tocilizumab); however, only one of them was diagnosed with COVID-19. Conclusion: The COVID-19 pandemic has not significantly disrupted the medical care of JSS patients. Telemedicine could be an acceptable option for JSS patients disenabled to come to the hospital.
RESUMO
Despite the advanced knowledge concerning autoinflammatory diseases (AID), more data regarding the optimal treatment options and outcomes of the children who met the criteria of more than one AID are required. This study aimed to describe the demographic and clinical characteristics of children from familial Mediterranean fever (FMF)-endemic countries who meet both the FMF and the periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome criteria. Moreover, we aimed to measure the response rates to colchicine and tonsillectomy and evaluate the factors affecting the colchicine response in these patients. The study was conducted at pediatric rheumatology tertiary centre. A total of 131 patients (58 females; 73 males) who met both the modified Marshall and pediatric FMF criteria were included. The median age at onset was 18 months (1-77 months), and the mean age at diagnosis was 47 ± 21.88 months. The median interval between episodes was 21 (7-90) days. The median disease duration was 46 (6-128) months. Consanguineous marriage was detected in 17 (13%) of the patients. The most common clinical finding was fever (100%), followed by exudative pharyngitis (88.5%), abdominal pain (86.3%), arthralgia (61.8%), stomatitis (51.1%), adenitis (42%), myalgia (28.7%), chest pain (16%), maculopapular rash (12.2%), arthritis (8.4%), and erysipelas-like rash (4.6%). MEFV gene variants were identified in 106 (80.9%) patients. The most common variants were M694V heterozygous (29%). We found that patients with tonsillopharyngitis, aphthous stomatitis, and PFAPA family history were more likely to be colchicine-resistant and tonsillectomy responsive, while those with exon 10 MEFV gene mutations were more prone to have a favorable response to colchicine. Conclusion: PFAPA syndrome patients with exon 10 MEFV gene mutation, showing typical FMF symptoms, should be treated with colchicine, even after tonsillectomy. In multivariate analysis, PFAPA family history and lack of exon 10 MEFV gene mutations were independent risk factors for colchicine resistance. Thus, tonsillectomy may be recommended as a possible treatment option for these patients. It has yet to be clarified when colchicine treatment will be discontinued in patients whose attacks ceased after tonsillectomy that was performed due to colchicine unresponsiveness. What is Known: ⢠A certain number of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome concomitantly fulfill the familial Mediterranean fever (FMF) criteria. ⢠While colchicine is proposed as a first treatment choice in familial Mediterranean fever (FMF), corticosteroids are recommended as a first-line treatment in PFAPA syndrome patients. What is New: ⢠In patients with concomitant PFAPA syndrome and FMF, PFAPA family history and lack of exon 10 MEFV gene mutation are predictive factors of colchicine resistance. ⢠The presence of exon 10 MEFV gene mutations in patients with concomitant FMF and PFAPA syndrome has a favourable effect on response to colchicine treatment.

Objective: To compare organ involvement and disease severity between male and female patients with juvenile onset systemic sclerosis. Methods: Demographics, organ involvement, laboratory evaluation, patient-reported outcomes and physician assessment variables were compared between male and female juvenile onset systemic sclerosis patients enrolled in the prospective international juvenile systemic sclerosis cohort at their baseline visit and after 12 months. Results: One hundred and seventy-five juvenile onset systemic sclerosis patients were evaluated, 142 females and 33 males. Race, age of onset, disease duration, and disease subtypes (70% diffuse cutaneous) were similar between males and females. Active digital ulceration, very low body mass index, and tendon friction rubs were significantly more frequent in males. Physician global assessment of disease severity and digital ulcer activity was significantly higher in males. Composite pulmonary involvement was also more frequent in males, though not statistically significantly. After 12 months, they are the pattern of differences changed female patients had significantly more frequent pulmonary involvement. Conclusion: In this cohort, juvenile onset systemic sclerosis had a more severe course in males at baseline and but the pattern changed after 12 months. Some differences from adult findings persisted, there is no increased signal of pulmonary arterial hypertension or heart failure in male pediatric patients. While monitoring protocols of organ involvement in juvenile onset systemic sclerosis need to be identical for males and females.
RESUMO
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.
RESUMO
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 Collaborating 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, activity 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.

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.
