RESUMO
OBJECTIVE: Granulomatosis with polyangiitis (GPA) is an ANCA-associated vasculitis. The 2022 ACR/EULAR-endorsed classification criteria for GPA was derived using data only from adult patients. We aimed to assess the performance of the ACR/EULAR classification criteria for GPA in paediatric patients and compare it with the EULAR/Pediatric Rheumatology International Trials Organization (PRINTO)/Pediatric Rheumatology European Society (PReS)-endorsed Ankara 2008 criteria for GPA. METHODS: Retrospective data of paediatric patients with GPA in 20 centres from 9 countries were evaluated. The diagnosis of GPA was made according to the expert opinion. The sensitivity, specificity, positive predictive value, and negative predictive value of the criteria sets were evaluated. RESULTS: The study included 77 patients with GPA and 108 controls [IgA vasculitis (n = 44), Takayasu's arteritis (n = 20), microscopic polyangiitis (n = 16), polyarteritis nodosa (n = 14), Behçet's disease (n = 12), eosinophilic granulomatosis with polyangiitis (n = 1) and Cogan's syndrome (n = 1)] with a median age of 17.8 and 15.2 years, respectively. Among patients with GPA, constitutional symptoms (85.7%) and ENT involvement (79.2%) were the most common presentations. In the GPA group, 73 patients fulfilled the Ankara 2008 criteria and 69 the ACR/EULAR classification criteria. Sensitivities of the Ankara 2008 criteria and the ACR/EULAR classification criteria were 94.8% and 89.6%, while specificities were 95.3% and 96.3%, respectively. No significant difference was found between sensitivities and specificities of both classification criteria (P = 0.229 and P = 0.733, respectively). CONCLUSION: In children, both the ACR/EULAR and EULAR/PRINTO/PReS Ankara 2008 classification criteria for GPA perform well and similarly.

OBJECTIVES: To investigate the severe haematological involvement in children with SLE and assess its clinical associations, treatments, outcome and damage accrual. METHODS: The medical charts of children with SLE in whom haematological involvement was observed were reviewed. Severe haematological indices were defined as autoimmune haemolytic anaemia with a haemoglobin concentration < 8 g/dL, thrombocyte count < 30 000/µL, and neutrophil count < 500/µL. RESULTS: Among the 224 patients included, 102 (45.5%) displayed severe indices, predominantly at the initial involvement, and most frequently as severe anaemia in 54 (24.1%) and severe thrombocytopenia in 45 (20.1%). Disease activity did not differ according to the presence of severe disease indices. In addition, the presence of severe indices at initial involvement did not affect the damage accrual. However, a higher rate of damage (51.1% vs. 29.9%, p = 0.002) and steroid-induced damage (28.9% vs. 8.2%, p < 0.001) was evident in patients with flares of the haematological system. Regression analysis revealed that rituximab treatment during the initial episode (OR:4.5, p = 0.006) and the presence of anticardiolipin antibodies (OR:2.3, p = 0.014) significantly increases the odds for haematological system flare. However, severe indices at initial involvement did not increase the odds of a haematological flare. CONCLUSION: Severe haematological indices at onset are common but not related with disease outcomes. Prevention of flares is important to improve outcomes, and a more rigorous maintenance strategy would benefit most to children who display haematological indices refractory to conventional immunosuppressants and those with anti-cardiolipin antibodies.
RESUMO
To evaluate the sleep quality and fatigue levels in children with familial Mediterranean fever (FMF) in comparison to healthy children. The Pediatric Quality of Life Multidimensional Fatigue Scale (PedsQL-MFS) and the Pittsburgh Sleep Quality Index (PSQI) were the instruments utilized to assess fatigue and sleep quality in children with FMF and controls, respectively. Spearman's rank coefficient was decisive in determining the association between patient-reported outcome measures and disease-related features. Two hundred twenty-five (59.3% female) patients and 182 (51.6% female) healthy counterparts were enrolled in the study. In PSQI, where high scores indicate sleep disturbance, the median score was significantly higher in the patient group (5; 3-6) than the control group (3; 2-4) (p < 0.001). PEDsQL-MFS demonstrated significantly lower fatigue levels in the control group than patients (p = 0.01). The level of fatigue in the patient group was found to increase in correlation with sleep problems (r: - 0.750, p < 0.001). Additionally, a high correlation was present between the PSQI/PedsQL-MFS scores and the number of attacks in the last year (r: - 0.645, p < 0.001/r: 0.721, p < 0.001, respectively). There was no difference in terms of fatigue and sleep disorders between mutations (homozygous, heterozygous, or compound heterozygous) in the MEFV gene (p > 0.05). Conclusion: High disease activity has a significant negative impact on the sleep quality and fatigue levels of patients with FMF. This study emphasizes the importance of assessing fatigue and sleep quality with objective outcome tools periodically in FMF patients throughout the disease course. What is Known: ⢠Fatigue is a common matter that often accompanies rheumatic diseases and causes disability. ⢠Chronic rheumatic diseases often experience poor sleep quality. What is New: ⢠In high correlation with the disease severity of familial Mediterranean fever, sleep quality decreases and fatigue level increases significantly. ⢠In familial Mediterranean fever patients, a negative correlation is present between age and the general fatigue and sleep/rest related fatigue scores (low scores indicating greater fatigue) and sleep quality is poorer in the adolescent age group.

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
OBJECTIVES: The purpose of this study is to evaluate the performances of recently proposed Pediatric Rheumatology International Trials Organization criteria versus current International League of Associations for Rheumatology criteria for systemic juvenile idiopathic arthritis (sJIA). METHODS: The study was performed at the Department of Pediatric Rheumatology in Istanbul Faculty of Medicine with a retrospective design, covering the date range 2010-2021. Patients diagnosed with sJIA, Kawasaki disease and common autoinflammatory diseases were included. Both the International League of Associations for Rheumatology and Pediatric Rheumatology International Trials Organization classification criteria were applied to each patient and cross-checked with expert rheumatologist diagnosis. RESULTS: Eighty-two patients with sJIA were compared against 189 (74 Kawasaki disease, 83 familial Mediterranean fever, 16 mevalonate kinase deficiency, 10 cryopyrin-associated periodic syndromes, and 6 tumour necrosis factor receptor-associated periodic syndrome) patients. The Pediatric Rheumatology International Trials Organization criteria demonstrated higher sensitivity (62.2% vs 80.5%, P =.003) but comparable specificity (90.5% vs 91%) as regards the International League of Associations for Rheumatology criteria. CONCLUSIONS: The revised criteria appear to enhance the ability to provide early recognition and pertinent classification of sJIA. No superiority was observed in segregating sJIA from common autoinflammatory diseases and Kawasaki disease, namely in terms of specificity.

BACKGROUND/OBJECTIVE: Juvenile spondyloarthropathies (JSpAs) are a group of inflammatory diseases characterized by asymmetric peripheral arthritis (especially in lower extremities), axial skeleton involvement, and enthesitis. Although cardiovascular findings of inflammatory diseases such as juvenile systemic lupus erythematosus (SLE) and juvenile scleroderma (SD) are well documented, there are only a few studies assessing the cardiovascular consequences of JSpA in the literature. METHODS: Forty patients with JSpA and 20 healthy controls were included into this cross-sectional study. Cardiac functions of the participants were evaluated by conventional echocardiography and pulse-wave (PW) tissue Doppler. RESULTS: The patients with JSpA had higher mitral lateral S (p = 0.005) and E' wave (p < 0.001), tricuspid A' wave (p = 0.03), ejection fraction (p = 0.03) and shortening fraction (p = 0.01) than the control patients. In contrast, the patients with JSpA had lower left ventricle MPI (p = 0.01) and the ratio of tricuspid E'/A' waves (p = 0.05). Patients with enthesitis detected on magnetic resonance imaging had lower ejection fraction (p = 0.05), the ratio of E/A waves (p = 0.03) and had higher Mitral lateral A' wave (p = 0.01) than those without. There was a significant inverse correlation between the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and PW transmitral A velocity (r = -0.256, p = 0.03), the BASDAI score and tricuspid annular plane systolic excursion (r = -0.301, p = 0.04), the BASDAI score and the ratio of E/E' waves (r = -0.276, p = 0.02), and the Juvenile Spondyloarthritis Disease Activity Index and PW transmitral A velocity (r = -0.246, p = 0.04). CONCLUSIONS: In this study, we report the possible early signs of RV diastolic dysfunction and possible association between magnetic resonance imaging-confirmed enthesitis and lower LV systolic functions. Early identification of cardiac dysfunctions can help with prevention of long-term cardiovascular complications.

This study was conducted to investigate the relationship between clinic features and Mediterranean fever gene (MEFV) variants in patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome. In total, 167 patients with PFAPA syndrome were included in the study. Female:male ratio of the patients was 0.75 (72 females, 95 males). In total 59.9% of patients with PFAPA had at least one MEFV variant and the most common heterozygous variants were M694V in 29.3% of the patients (40/167), E148Q in 8.3% (14/167), and V726A in 7.1% (12/167). The median age at the disease onset was significantly higher and the median duration of the episodes was significantly lower in patient with variants in exon 10 comparing to the others (both p = 0.01). Similarly, the median age at the disease onset was significantly higher (p = 0.01) and the median duration of the episodes was significantly lower (p = 0.04) in patient with MEFV variants than in the remaining patients. There were no significant differences according to the genotypes of the patients in terms of both treatment response and the frequency of clinical findings.Conclusion: In PFAPA syndrome, MEFV variants may be a modifier for disease onset and attack duration. What is Known: ⢠Due to periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome having clinical findings resembling familial Mediterranean fever (FMF), it can be difficult to distinguish PFAPA syndrome and FMF especially in endemic regions for FMF. ⢠Underlying MEFV mutations could affect the periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome's clinical presentation and response to treatment. What is New: ⢠Having one of the underlying MEFV variants is related to later disease onset and shorter episode duration in patients with PFAPA syndrome.

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.

BACKGROUND: Anti-nuclear antibody (ANA) testing is most commonly ordered by general pediatricians to evaluate children with musculoskeletal system complaints. Given the limited utility of the test, we aimed to estimate the effectiveness of ordering ANA testing in childhood. METHODS: Children referred to our department to be examined due to positive ANA findings between 2008 and 2020 were included in the study. Those with less than one-year follow-up period, those with previously known rheumatic or autoimmune disease, and those diagnosed as an autoimmune and/or rheumatic disease at the first visit were excluded. Data were obtained from their medical records, retrospectively. The parents of all of the patients were called via phone, data were verified, and missing information was collected. RESULTS: Three hundred and fifty-eight patients (230 females) were eligible for the study. The median age of positive ANA findings was 9.31 (1.3-17.86) years and the median follow-up duration was 4.85 (1-11.91) years. Most of the patients had no underlying disease (n = 337, 94.1%). The most common reason for ordering ANA testing was to evaluate musculoskeletal system symptoms (n = 225, 62.8%). None of our patients referred to us due to positive ANA findings developed any autoimmune conditions or ANA associated rheumatic disease. Hypermobility syndrome is the most common final diagnosis among our ANA-positive patients. CONCLUSION: We suggest that instead of using it as a screening tool, ANA testing should be performed only if there is a strong suspicion of autoimmune diseases or certain rheumatic conditions, such as systemic lupus erythematosus.

OBJECTIVES: To determine and compare the effectiveness of history, physical examination, conventional radiography and magnetic resonance imaging (MRI) in the detection of sacroiliitis in juvenile spondyloarthropathies. METHODS: One hundred and one patients with JSpA, 33 patients with other diseases and 24 children without rheumatologic complaints were included in the study. Subjects were evaluated using physical examination, laboratory findings, pelvic radiography and MRI. Abdominal or pelvic MRIs of 24 control patients who were obtained in the last 6 months were reevaluated and multivariate logistic regression analyses were used to calculate probability ratios of variables. RESULTS: In our study, the rate of active sacroiliitis was 52.4% and in most of them, erosive and sclerotic changes indicating destruction of the sacroiliac joints were recorded. The presence of sacroiliitis on direct x-ray, high JSPADAI score, and hip involvement on MRI were independent risk factors with high predictive potential for active sacroiliitis. Inflammatory lumbar pain, sacroiliac tenderness, modified Schober's limitation, acute phase elevation, HLA-B27 positivity and presence of uveitis failed to predict sacroiliitis. The best specificity was 100% with a high BASFI score (>5), then 94% with a high JSPADAI score (>4). None of the patients in the control group showed active sacroiliitis. CONCLUSIONS: All patients with possible JSpA should undergo sacroiliac MRI whether HLA-B27 positive or not. In this way, early diagnosis and treatment of axial joint involvement could be possible and it prevents unnecessary examination and loss of time.

Concerns regarding the comorbidity as a significant risk factor for Coronavirus Disease-2019 (COVID-19), gave rise to an urgent need for studies evaluating patients with chronic conditions such as autoinflammatory diseases (AIDs). We prepared a web-based survey investigating the clinical findings and contact histories among pediatric patients with AIDs. Confirmed COVID-19 cases, patients with contact history and those with symptoms which were highly suggestive of COVID-19 were called via phone or recruited to a video or face to face appointment. Data of AIDs were obtained from their medical records, retrospectively. Laboratory and screening findings were confirmed by our national health registry website. There were 404 patients (217 female) eligible for the enrollment. During pandemic, 375 (93%) were on colchicine treatment and 48 (11.8%) were receiving biologic treatment. Twenty-four out of 404 patients were admitted to hospital due to COVID-19 suspicion. Severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) was identified through rhinopharyngeal swabs in seven patients, six of whom were only on colchicine treatment. Only one patient with no finding of any severe respiratory complications was hospitalized. All of seven patients recovered completely. Among patients on biologic drugs, neither a symptom nor a positive polymerase chain reaction test for COVID 19 was detected. In conclusion, pediatric patients with AIDs, those receiving biologic treatment and/or colchicine, may not be at increased risk for neither being infected nor the severe disease course.

Familial Mediterranean fever (FMF) is A common periodic fever syndrome. The causative gene of the FMF is named Mediterranean Fever gene (MEFV). Increased inflammation in FMF may play a role as a trigger for the development of some diseases. The objective of the study is to evaluate the frequency of comorbid disorders in children followed up with diagnosis of FMF. Additionally, we aimed to assess the association between FMF and other inflammatory conditions in a large pediatric FMF cohort. A total of 686 FMF patients were included in the cross-sectional study. A questionnaire including questions about characteristics of fever episodes, presence of arthralgia, arthritis, abdominal pain, chest pain during and co-existence of any other disease diagnosed by a physician was filled out by face-to-face interviews with patients or their parents. Female-male ratio was 0.85. Median age at the time of study, age at disease onset and at the time of diagnosis were 12.9 (1.7-22.3), 3 (0.08-17), and 6 (0.75-17) years, respectively. In 130 (18.9%) FMF patients we detected co-existing inflammatory condition. The most common co-existing diseases were: juvenile idiopathic arthritis 42 (6.1%), asthma/reactive airway disease 29 (4.2%), Henoch-Schönlein purpura 20 (2.9%), uveitis 12 (1.7%) and inflammatory bowel disease 10 (1.4%). Except for asthma/reactive airway disease and inflammatory bowel disease, there was no significant difference regarding the type of MEFV gene mutation. We have reported increased frequencies of various inflammatory conditions and decreased frequency of asthma in patients with FMF.

The periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is an auto-inflammatory condition characterized by recurrent episodes of fever accompanied by aphthosis, cervical adenitis, and pharyngitis. Diagnosis of PFAPA could be challenging due to clinic overlap with familial Mediterranean fever (FMF). An international consensus has been established recently, to define a new set of classification criteria for PFAPA syndrome. We aimed to evaluate the performance of recently proposed PFAPA criteria, to assess their utility in FMF regions. Patients diagnosed with PFAPA syndrome, FMF, and juvenile idiopathic arthritis (JIA) were included. Two investigators blindly evaluated all of patients for the newly proposed PFAPA criteria. A total of 542 patients (322 with PFAPA syndrome, 118 FMF and 102 JIA) were evaluated. Mean age of patients was 6.6 ± 2.81, 12.75 ± 3.9, and 12.42 ± 4.8 years for PFAPA, FMF, and JIA, respectively. We found quite high sensitivity (89.7%) but insufficient specificity of newly proposed PFAPA criteria (69.5%). When applied to control patients separately, specificity was found to be 61% and 79.4% for FMF and JIA patients, respectively. Positive predictive value was 81%, while negative predictive value was 82%. Recently proposed PFAPA criteria have satisfactory sensitivity, but its specificity is still under expectation. There is a need for a distinctive criterion between PFAPA syndrome and FMF, in FMF endemic regions, e.g., cryptic tonsillitis rapidly responsive to single dose of glucocorticoids. Further studies with higher patients' number in different regions are needed.

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.

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

The objective is to evaluate the walking distance and oxygen desaturation during the six-minute walk test and to establish correlations between the test results and other clinical findings so to assess the reliability of the test for evaluation of children with juvenile systemic sclerosis (jSSc). A total of 25 jSSc, 27 juvenile systemic lupus erythematosus (jSLE), and 30 healthy controls were included. The test is conducted according to the guidelines recommended by the American Thoracic Society, standardized in 2002. Median values of walking distances were 470 (415-580) m in jSSc; 518 (376-618) m in jSLE; and 562 (493.5-618) m in healthy controls. jSSc patients walked significantly less distance comparing to controls (p < 0.001). jSSc patients with lung involvement walked less than those without lung involvement [463.2 (418-565) m vs. 491.5 (415-580) m], but without a significant difference (p = 0.82). The frequency of lower extremity pain during and after the test was significantly higher in the jSSc cohort compared to both control groups (p = 0.001). Patients with myalgia were found to walk less than those without myalgia [446.5 (415-538) m vs. 493.5 (428-580) m] (p = 0.04). Patients with jSSc have limited walking distances. Despite the decreased walking distance among jSSc patients with ILD and/or PAH, the limited number of patients makes the results inappropriate for interpretation. Low extremity pain influences the walking capacity of jSSc patients.

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.

In our study, in which the relationship between juvenile idiopathic arthritis (JIA) and particular environmental factors was evaluated, a correlation could not be established between the rate or duration of breastfeeding and the development or severity of the disease. Int J Rheum Dis, 25, 2022, 1376. It was determined that the time of introduction to cow's milk differed in JIA and juvenile-onset systemic lupus erythematosus patient groups compared to healthy controls. On the other hand, the fact that income level and maternal literacy were associated with high disability and damage scores and frequent recurrence rates stood as one of the remarkable results of our study. Kao et al drew attention to the relationship between socioeconomic status and chronic arthritis and quoted an adult study. The role of the parent factor has been stressed and the effect of maternal stress on disease development has been discussed. Although JIA is a heterogeneous disease and the tribulation of measuring the direct impact of environmental elements are limiting factors, it is essential to determine the parts that can be controlled to some extent and the precautions to be taken.

The presence of mucocutaneous manifestations has clinical significance, as it may be a part of the initial presentation or activation stage of both autoimmune and autoinflammatory rheumatic diseases. The cutaneous signs may display a particular morphological and topographic distribution according to taxonomy, whereas heterogeneity is likely observed among the individuals. The review aims to cluster and systematically approach the mucocutaneous manifestations met in autoimmune and autoinflammatory rheumatic diseases of childhood. The search strategy involved a comprehensive inquiry on Web of Science, PubMed, MEDLINE, and Embase databases using relevant search terms such as "dermatologic, cutaneous, mucocutaneous, skin, rash" for each disease and category. The awareness of the distinctive mucocutaneous manifestations and their correlation with rheumatic diseases provides a convenient definition, well-timed control of the underlying condition, and prevention of cosmetic issues. In the management of rheumatic diseases, planning the pertinent differential diagnosis and determining the requirement of histopathological assessment are essential with a multidisciplinary approach to rheumatology, dermatology, and allergy-immunology specialties.

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.
