[PMID: 37870706 DOI: 10.1007/s11845-023-03555-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 10/18/2023] [Indexed: 10/24/2023]
Abstract
BACKGROUND-AIM To evaluate the effect of vitamin D supplementation on the frequency and duration of attacks in patients of PFAPA syndrome with low vitamin D levels. METHODS This retrospective study comprised PFAPA patients with vitamin D deficiency/insufficiency between 2018 and 2023. The frequency and duration of PFAPA attacks before and after vitamin D supplementation were noted. RESULTS Seventy-one patients were included. Of the 71 patients, 24 (33.8%) had vitamin D insufficiency, and 47 (66.2%) had vitamin D deficiency. In patients with vitamin D insufficiency, mean attack frequency and mean attack duration before vitamin D supplementation were 4.3 ± 1.9/year and 2.2 ± 1.6 days, respectively, while mean attack frequency and mean attack duration after vitamin D supplementation were 3.5 ± 2.7/year per year and 1.3 ± 0.9 days respectively (p = 0.2, p = 0.2, respectively). In patients with vitamin D deficiency, mean attack frequency and mean attack duration before vitamin D supplementation were 7.4 ± 2.1/year and 2.2 ± 1.6 days, respectively, while mean attack frequency and mean attack duration after vitamin D supplementation were 3.3 ± 2.4/year and 1.3 ± 0.9 days respectively (p < 0.01, p = 0.04, respectively). When the vitamin D level and the frequency of attacks were compared, the cut-off value of vitamin D was found to be 29.7 nmol/L. CONCLUSIONS In PFAPA patients with low vitamin D levels, the frequency and duration of PFAPA attacks were reduced with vitamin D supplementation. Especially at vitamin D level cut-off > 29.7 nmol/L, the frequency of attacks reduced significantly.

When should the use of biological agents be considered in persistent oligoarticular juvenile idiopathic arthritis patients? Eur J Pediatr 2024:10.1007/s00431-024-05538-y. [PMID: 38554171 DOI: 10.1007/s00431-024-05538-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 03/19/2024] [Accepted: 03/21/2024] [Indexed: 04/01/2024]
Abstract
The purpose of this study was to compare the demographic and clinical characteristics of the groups with and without bDMARDs added to the treatment of persistent oligoarticular juvenile idiopathic arthritis (JIA) patients on methotrexate (MTX) and also to determine the predictors of adding bDMARDs to treatment. This study included 86 oligoarticular JIA patients on MTX. Patients were divided into two groups receiving MTX (n = 69) and MTX plus bDMARD (n = 17). Predictors of adding bDMARDs were investigated by comparing demographic, clinical features and laboratory findings. Gender, age at diagnosis, time elapsed from the onset of symptoms to diagnosis, and disease duration, the number and distribution of affected joint at the time of diagnosis were similar in both groups. The mean JADAS10 at the time of diagnosis were 18.8 ± 4.2 and 19.5 ± 6.4 in the MTX and MTX plus bDMARDs groups, respectively (p = 0.68). JADAS10 at 3rd and 6th month were significantly higher in patients on MTX plus bDMARDs (p = 0.001, p = 0.004, respectively). In multivariate analysis, the risk of adding bDMARD was shown to increase 1.24-fold (p = 0.004, 95% CI: 1.07-1.43) for each point increase on the JADAS 10 at 3rd months. The number (p = 0.64) or type (p = 0.18) of joint involvement at disease onset were not predictors of adding a bDMARD. CONCLUSION JADAS10 indicating ongoing severe disease activity at 3rd and 6th months rather than baseline JADAS10 is associated with the addition of bDMARDs. WHAT IS KNOWN • Oligoarticular JIA patients have the best outcomes among JIA categories and respond favorably to first-line therapies such as non-steroidal anti-inflammatory drugs and intraarticular corticosteroid injections. • Clinically inactive disease rates have increased with the widespread use of biological agents in oligoarticular JIA patients who have not responded to initial therapies. WHAT IS NEW • Approximately one-fifth of patients with persistent oligoarticular JIA on methotrexate may require the addition of a biological disease modifying anti-rheumatic drug during follow-up. • The JADAS10 calculated at 3 and 6 months is a valuable tool to identify patients who should be added biological disease modifying anti-rheumatic drugs in persistent oligoarticular JIA.

Assessment of quality of life, school performance, and physical activity in adolescents with Familial Mediterranean fever. Mod Rheumatol 2024; 34:405-409. [PMID: 36790108 DOI: 10.1093/mr/road022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/02/2023] [Accepted: 02/04/2023] [Indexed: 02/16/2023]
Abstract
OBJECTIVES The aim of this study is to evaluate differences in school performance, school attendance, quality of life, and physical activity in adolescents with Familial Mediterranean fever (FMF) compared to healthy controls. METHODS One hundred and twenty-nine patients with FMF and 154 healthy controls between 13 and 18 years were included in the study. Demographic, school performance (according to grade point average), school absenteeism, and type and frequency of exercise were recorded. Quality of life was evaluated with the Pediatric Quality of Life Inventory (PedsQL) 4.0. RESULTS The mean age of FMF patients was 15.1 ± 2.7 years, and 69 patients (53.5%) were female. School performance was significantly higher in the control group compared to FMF patients (P < 0.001). In the control group, there were significantly higher participants who engaged in professional sports (P < 0.001). Patients with FMF had significantly lower self-reported PedsQL scores in school functioning, physical, and psychosocial health domains compared to those in the control group (P = 0.001, P < 0.001, and P = 0.028, respectively). CONCLUSIONS FMF patients demonstrated lower school performance and quality-of-life scores compared to healthy controls. In addition to improving symptoms in chronic diseases, it is important to evaluate and improve the quality of life of patients in routine practice and to ensure psychosocial well-being.

Assessment of quality of life and physical activity in patients with oligoarticular juvenile idiopathic arthritis in remission. Eur J Pediatr 2024; 183:955-964. [PMID: 38071637 DOI: 10.1007/s00431-023-05367-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/22/2023] [Accepted: 12/03/2023] [Indexed: 03/05/2024]
Abstract
The purpose of this study was to evaluate physical activity (PA) and health-related quality of life (HRQOL) in children with oligoarticular juvenile idiopathic arthritis (JIA) in remission in comparison with healthy peers and to determine the disease-related factors affecting PA levels. This study was conducted with 50 oligoarticular JIA patients in remission and 50 healthy peers between 9 and 14 years. Demographic and clinical characteristics, laboratory parameters, and treatments were noted from electronic medical records. HRQOL was assessed with the Pediatric Quality of Life Inventory (PedsQL). PA was evaluated with the Physical Activity Questionnaire for Children (PAQ-C). Oligoarticular JIA patients had significantly lower self-reported median PedsQL scores in the domains of school functioning and social functioning compared to the control group (67.5 (10) vs. 75 (25), p = 0.001 and 70 (15) vs. 85 (26.3), p < 0.001, respectively). The median PAQ-C score was 2.6 (1.1) in patients with JIA and 3 (0.9) in their healthy peers (p = 0.02). The PAQ-C score was 2.8 (1.2) in patients < 8 years at the disease onset and 2.3 (1) in those aged ≥ 8 years (p = 0.022). There was no significant difference in the number of affected joints, type of affected joint, MTX and biologic agent treatment, and remission with or without drugs with the total score of the PedsQL and PAQ-C. All PedsQL domains were positively correlated with the PAQ-C. Conclusion: Oligoarticular JIA patients demonstrated lower PA and HRQOL scores compared to healthy controls despite favorable disease control. What is Known: • Oligoarticular JIA has fewer functional limitations and disabilities compared to other JIA subtypes. • As JIA can affect all aspects of a child's life, there is a need to improve the quality of life related to the disease. What is New: • It should be considered that patients with oligoarticular JIA may show lower PA and HRQOL scores compared to healthy controls despite favorable disease control. • Since there may be a relationship between PA and HRQOL, factors that may affect PA should be investigated to provide a holistic approach to JIA treatment.

Age-related differences in the clinical phenotypes of Behçet's disease: The experience of two referral centres. Mod Rheumatol 2023; 34:194-200. [PMID: 36688579 DOI: 10.1093/mr/road012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 12/13/2022] [Accepted: 01/02/2023] [Indexed: 01/24/2023]
Abstract
OBJECTIVES Behçet's disease (BD) is a multisystem disease and frequently occurs during the second-fourth decades of life, although disease onset may be seen at any age. This study aimed to analyze the influence of the age of onset on clinical manifestations of BD. MATERIALS AND METHODS This retrospective study analyzed two cohorts (paediatric and adult) to determine the association between the age of onset and clinical features in BD. Patients were classified into four groups to analyze the clinical characteristics according to the age of fulfilling the BD diagnostic criteria as follows: childhood onset (<12 years), adolescent onset (13-17 years), adult onset (18-39 years), and late onset (>40 years). RESULTS The study included 801 patients with BD. Male predominance, pathergy test positivity, aphthosis (oral or genital), and skin and ocular involvements were higher among adult patients than paediatric patients. The presence of positive family history for BD, neuro-BD, and epididymitis were observed significantly common in the paediatric group. CONCLUSION There may be differences in clinical manifestations with regard to the age of disease onset. Disease presentations may differ from adult patients, and clinicians should be aware of the high familial aggregation rate of BD, especially in countries where the disease is endemic.

Does switching from coated colchicine to compressed colchicine improves treatment response in patients with familial Mediterranean fever? Croat Med J 2023; 64:354-361. [PMID: 37927190 PMCID: PMC10668039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 10/20/2023] [Indexed: 11/07/2023] Open
Abstract
AIM To evaluate the treatment response to compressed colchicine tablets in familial Mediterranean fever (FMF) patients with resistance or intolerance to coated colchicine. The secondary aim was to determine the demographic and clinical characteristics of responders to compressed colchicine. METHODS We retrospectively reviewed the medical records of 1574 pediatric patients with FMF treated at Ankara Bilkent City Hospital. Sixty-one patients did not respond to coated colchicine and were switched to compressed colchicine. In these patients, the number of attacks and the International Severity Score for FMF (ISSF) during the 6 months before and 3, 6, 9, 12, and 24 months after switching from coated colchicine to compressed colchicine were recorded. RESULTS Twelve of 61 patients (19.7%) who were switched to compressed colchicine due to intolerance responded to treatment. Of the 49/61 patients (80.3%) who were switched due to uncontrolled attacks and persistent subclinical inflammation, 25 responded to treatment. The frequency of attacks and ISSF decreased after switching. At the end of the two-year follow-up, 42 patients responded to compressed colchicine, and 19 patients received compressed colchicine plus interleukin-1-targeting drugs. CONCLUSIONS Compressed colchicine was shown to be a useful treatment option before initiating biological agents in non-responders to coated colchicine, especially those with side effects.

Abstract
OBJECTIVES Our study aimed to evaluate the relationship of small joint involvement with demographic, clinical, and laboratory findings and to determine its possible effects on prognosis. METHODS This retrospective observational study was conducted in patients diagnosed with oJIA in the pediatric rheumatology department of our hospital between April 2009-September 2022. The relationship between small joint involvement and demographic, clinical, laboratory findings and prognosis were investigated by statistical methods with the data recorded from the medical records of oJIA patients. RESULTS Of the 198 patients diagnosed with oJIA, small joint involvement was observed in a total of 20 (10%) patients, 11 (5.5%) at the time of diagnosis, and 9 (4.5%) during the follow-up period. The frequency of small joint involvement in extended oJIA was significantly higher than in persistent oJIA (p=0.001). Patients with small joint involvement had significantly higher ESR and CRP values at admission (p=0.047, p=0.038) and the JADAS at 3, 6, and 12 months (p=0.001, p=0.001, p=0.018). The need for cDMARDs and bDMARDs was significantly higher in patients with small joint involvement (p=0.001, p=0.001). CONCLUSIONS oJIA patients with small joint involvement may have higher acute phase reactants at diagnosis, a more extended course and active disease in follow-up, and the need for treatment escalation.

Abstract
BACKGROUND The Eurofever/the Pediatric Rheumatology International Trials Organization (PRINTO) classification criteria for familial Mediterranean fever (FMF) include a combination of clinical symptoms and genotype. The pathogenicity of gene variants associated with FMF is categorized by the International Study Group for Systemic Autoinflammatory Diseases (INSAID) classification criteria. OBJECTIVE The aim of this study was to evaluate the real-life impact and usefulness of the Eurofever/PRINTO classification criteria and the INSAID classification criteria in patients with FMF and their impact on treatment management. METHODS In this medical records review study, the files of FMF patients who met the Eurofever/PRINTO classification criteria were reviewed. The MEFV (MEditerranean FeVer) variants were grouped according to the INSAID classification criteria. RESULTS Of the 1062 patients, the female-to-male ratio was 1:1.01. In group 1, there were 150 patients (14.1%) who met the clinical criteria. Group 2 consisted of 912 patients (85.9%) who met the criteria according to genetic variants. The mean ages at symptom onset in groups 1 and 2 were 5.6 ± 3.8 and 1.5 ± 1.2 years, respectively ( p = 0.024). Whereas the mean annual attack frequency was 2.7 ± 3.1/year in group 1, it was 4.1 ± 2.3/year in group 2 ( p = 0.04). The pathogenic variant was higher in the colchicine-resistant group compared with the responders ( p = 0.12). CONCLUSIONS The Eurofever/PRINTO classification criteria may provide a new perspective on the diagnosis and clinical follow-up of FMF patients. Patients with a pathogenic variant who meet the Eurofever/PRINTO classification criteria including genetic variables have earlier onset of disease and more frequent attacks than those who meet the criteria including clinical variables. These patients need regular and closer follow-ups in terms of attack frequency, colchicine dose adjustment, and colchicine resistance.

Abstract
OBJECTIVE To compare enthesitis-related arthritis (ERA) patients with active and inactive disease at 6 months and define baseline predictors for disease inactivity. In addition, to evaluate the demographic, clinical, and laboratory characteristics of ERA patients and to identify the real-life impact of the Juvenile Spondyloarthritis Disease Activity Index (JSpADA) in predicting active disease in ERA. METHODS This medical record review study was conducted with 56 patients who were diagnosed with ERA at our clinic between June 2009 and June 2022. Demographic and clinical characteristics, laboratory parameters, treatment, and JSpADA were recorded. RESULTS The patients were divided into 2 groups as active (n = 34) and inactive (n = 22) according to their disease activity at month six. Sex, age at diagnosis, number and type of affected joints, and presence of sacroiliitis were similar in both groups. There was no difference in baseline erythrocyte sedimentation rate, but there was a significant difference in erythrocyte sedimentation rate at the third month ( p = 0.52 and p = 0.018, respectively). The median JSpADA values at disease onset were 3.5 (interquartile range [IQR], 3.0-4.5) and 3.3 (IQR, 2.5-4.0) in the active and inactive groups, respectively ( p = 0.27). At the third month, the median JSpADA values were 1.5 (IQR, 0.5-2.1) in the active group and 0.5 (IQR, 0.5-1.5) in the inactive group ( p = 0.037). The cutoff value for JSpADA at the third month for active disease persisting at the month six was determined as 1 point (area under the curve, 0.662 ± 0.06; p = 0.042; 95% confidence interval, 0.51-0.80) by receiver operating characteristic curve analysis. CONCLUSION In ERA patients, a persistently high JSpADA value at follow-up is a predictive factor for active disease at the sixth month.

Predictors of relapse in patients with oligoarticular juvenile idiopathic arthritis in remission off medication. Eur J Pediatr 2023; 182:4557-4564. [PMID: 37526705 DOI: 10.1007/s00431-023-05123-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 07/12/2023] [Accepted: 07/17/2023] [Indexed: 08/02/2023]
Abstract
The aim of this study was to evaluate the predictors of relapse in patients with oligoarticular juvenile idiopathic arthritis (oJIA) who achieved clinical remission off medication. This retrospective observational study was conducted between June 2009 and July 2022 in 126 patients with oJIA who achieved remission off medication. The relationships between relapse status and demographic, clinical and laboratory findings, and treatment details were evaluated using electronic medical records. Of the 126 oJIA patients who achieved remission off medication, 85 (67.5%) were female. Relapse occurred in 31 patients (24.6%) with remission off medication after a median of 18 months (IQR 7-26). No statistically significant relationship was found between gender, age at diagnosis, oJIA subtype, number of joints, ANA, ESR, CRP level, initial Juvenile Arthritis Disease Activity Score and relapse in oJIA patients who achieved remission off medication (p = 0.66, p = 0.25, p = 1, p = 0.54, p = 0.29, p = 0.59, p = 0.95 and p = 0.52, respectively). There was a statistically significant relationship between the number of intraarticular corticosteroid injections (IACIs) and relapse (p = 0.01). Patients who underwent IACI 2-3 times had more relapses than those who never underwent IACI and those who underwent IACI only once (p = 0.01, p = 0.02, respectively). A relationship was found between the length of follow-up and relapse in patients with oJIA who achieved remission off medication (p = 0.035). Conclusion: In oJIA patients who achieve remission off medication, the probability of relapse increases in patients who need ≥ 2 IACI during the period until remission. The length of follow-up period is associated with the probability of relapse. What is Known: • Approximately one-fourth of oJIA patients who are in remission off medication have relapse. • There is a need for markers that can predict the risk of relapse in oJIA patients who achieve remission on or off medication. What is New: • The possibility of relapse should be considered in patients with oJIA who need ≥ 2 IACIs until achieving remission off medication. • The relapse rate may increase as the follow-up period prolongs in patients who achieve remission off medication.

Abstract
OBJECTIVE The purpose of this study is to investigate the causes and outcomes of switching biological agents in juvenile idiopathic arthritis (JIA) patients using biological agents and compare the characteristics of patients whose biological agents are switched and those whose are not. METHODS This medical records review study was conducted with 128 patients who were diagnosed with JIA at our clinic between January 2009 and January 2022 and were receiving biologic agents. Factors affecting the biologic agent switching were investigated. RESULTS The JIA subtype with the most frequent switching in biological agents was systemic JIA (n = 13, 40.6%). Systemic JIA was followed by rheumatoid factor-negative polyarticular JIA and persistent oligoarticular JIA with 5 patients (15.6%), extended oligoarticular JIA and enthesitis-related JIA with 3 patients (9.3%), rheumatoid factor-positive polyarticular JIA with 2 patients (6.2%), and undifferentiated JIA with 1 patient (3.1%). Among the patients, 32 (25%) patients had their biological agent switched once, and 5 (3.9%) had theirs switched twice. The most frequently used biological agent was etanercept (n = 76, 59.3%), whereas the most frequently observed cases of biological agent switching were from an anti-TNF agent to another anti-TNF agent (40.6%). The reason for switching was unresponsiveness to the agent in 22 patients (68.8%), adverse effects in 6 patients (18.7%), drug intolerance in 1 patient (3.1%), and other reasons in 3 patients (9.3%). CONCLUSIONS The most frequently used biological agent was etanercept; the most frequent cases of biological agents switching were from an anti-TNF agent to another anti-TNF agent.

Abstract
OBJECTIVE The present study aimed to compare the demographic, clinical, and laboratory characteristics of patients with pediatric Behçet disease (BD) with and without thrombosis to elucidate the factors that may contribute to the development of thrombosis. METHODS This observational, descriptive, medical records review study included patients with BD (n = 85) who were diagnosed at age younger than 16 years at our clinic between 2010 and 2022. The demographic, clinical, and available laboratory data of patients with and without thrombosis were compared. The potential risk factors for the development of thrombosis were evaluated with multivariable logistic regression analysis. RESULTS Central venous sinus thrombosis was the most common type of thrombosis. Thrombosis was significantly more common in male patients ( p = 0.002), and regression analysis revealed that being male was a risk factor for developing thrombosis. Genital ulcers were less common in patients with thromboses. Patients with thrombosis had higher erythrocyte sedimentation rates, C-reactive protein, leukocyte, and neutrophil counts, as well as antinuclear antibody positivity. In contrast, mean platelet volume and lymphocyte counts were significantly lower in patients with thrombosis. According to the logistic regression analysis, erythrocyte sedimentation rate value >17 mm/h was a risk factor for developing thrombosis (odds ratio, 1; confidence interval, 1.1-1.8; p = 0.012). CONCLUSIONS Male sex has been associated with an increased risk of thrombosis in children with BD. Inflammatory parameters may serve as predictive factors for thrombosis in pediatric BD.

Abstract
BACKGROUND Immunoglobulin A vasculitis with nephritis (IgAVN) is the most serious complication affecting long-term prognosis. Understanding the risk factors and markers for the development of IgAVN is essential. The aim of this study is to identify IgAVN-associated factors and to evaluate the usability of Pediatric Vasculitis Activity Score (PVAS) at diagnosis as an early marker for the development of IgAVN. METHODS We conducted a retrospective case-control study of 314 patients divided into two groups: those with nephritis (IgAVN) and without nephritis (non-IgAVN). The groups were compared in terms of clinical symptoms, laboratory values, and PVAS values. RESULTS In total, 18.5% of the patients had IgAVN; they were older than the non-IgAVN patients (median age was 8.8, p < 0.05). Arthritis/arthralgia, abdominal pain, and intestinal bleeding were more common, systolic and diastolic BP were higher in IgAVN (p < 0.05). CRP, serum creatinine, and urine protein/Cr, PVAS were higher, while serum albumin was lower in IgAVN (p < 0.05). The receiver operator characteristic curve (ROC) analysis showed that IgAV patients with a determined cut-off PVAS value greater than 3 had 70.7% sensitivity in predicting whether or not they would develop IgAVN. Logistic regression analysis found that PVAS > 3 and low serum albumin at the time of diagnosis were independent risk factors for IgAVN. CONCLUSION Our study revealed that PVAS > 3 at diagnosis is an independent predictor of IgAVN. Patients with PVAS > 3 should be followed more closely to ensure early diagnosis and management of IgAVN. A higher resolution version of the Graphical abstract is available as Supplementary information.

[PMID: 36780151 DOI: 10.1111/ped.15504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 01/21/2023] [Accepted: 02/05/2023] [Indexed: 02/14/2023]
Abstract
BACKGROUND The purpose of this study was to compare the demographic, clinical and laboratory characteristics of patients with enthesitis-related arthritis (ERA), familial Mediterranean fever (FMF) and inflammatory bowel disease (IBD), which are inflammatory diseases that may develop sacroiliitis. Thus, it was aimed to reveal various findings that may indicate primary disease in patients with sacroiliitis. METHODS Pediatric patients aged 6-18 years, who were being followed with a diagnosis of ERA (n=62), FMF (n=590), and IBD (n=56) over the period 2013-2021 were included in the study. Sacroiliitis (n=55) was diagnosed by magnetic resonance imaging (MRI) of the sacroiliac joint, obtained from clinically suspected patients. RESULTS Sacroiliitis was detected in 54.8% of ERA patients, 2.3% of FMF patients, and 12.5% of IBD patients. The mean follow-up period was 4.1±2.8 years (10months-8 years) for the entire study group. The most common MRI findings for sacroiliitis was bone marrow edema. Peripheral joint involvement (73.5%) and HLA B27 positivity (64.7%) was significantly higher in ERA patients, and ERA was diagnosed more frequently in patients presenting with sacroiliitis. Non-steroidal anti-inflammatory drugs (NSAIDs) were the first choice of treatment agent when sacroillitis developed in all three patient groups. CONCLUSIONS The clinical and laboratory findings of ERA, FMF and IBD can sometimes be intertwined or can even coexist. Treatment may differ depending on the disease associated with sacroiliitis, although NSAIDs may be used in the first-line treatment of all 3 diseases. Sacroiliitis patients with HLA B27 positivity and peripheral arthritis may need to be addressed as ERA.

Intussusception as a rare manifestation of immunoglobulin A vasculitis: Risk factors and treatment. J Paediatr Child Health 2023; 59:505-511. [PMID: 36692146 DOI: 10.1111/jpc.16335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/10/2023] [Accepted: 01/11/2023] [Indexed: 01/25/2023]
Abstract
AIM To identify the risk factors associated with intussusception in children with immunoglobulin A vasculitis (IgAV)-gastrointestinal (GI) tract involvement and to evaluate the outcomes of medical treatment and surgical intervention and the course of patients with intussusception. METHODS This retrospective study was conducted in 157 patients under 18 years of age who were followed up with the diagnosis of IgAV-GI tract involvement between January 2015 and September 2022. The characteristics of the patients who developed intussusception were evaluated in detail. RESULTS One hundred and fifty-seven patients with GI tract involvement were included in the study. The mean age of patients with IgAV-GI tract involvement was 8.7 ± 3.7 years. The female-to-male ratio was 1:1.5. Intussusception was detected in 14 patients (8.9%). Two patients (14.3%) underwent surgery, and the remaining 12 patients (85.7%) had their medical therapy intensified. Patients with GI tract involvement were divided into two groups as with (n = 14) and without (n = 143) intussusception. There was a statistically significant difference between the groups in the time from the onset of the first symptom of IgAV to the onset of steroids (P = 0.001). There were no statistically significant differences between the groups in age at onset of IgAV, gender distribution, erythrocyte sedimentation rate and C-reactive protein levels. CONCLUSIONS The time from the onset of the first symptom of IgAV to the start of steroids is a risk factor for the development of intussusception in patients with IgAV-GI tract involvement. In these patients, medical treatment usually reduces intussusception without the need for surgical intervention.

Preadolescent-versus adolescent-onset immunoglobulin A vasculitis: The impact of age on prognosis. Pediatr Int 2023; 65:e15426. [PMID: 36416667 DOI: 10.1111/ped.15426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 11/15/2022] [Accepted: 11/22/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND This study aimed to investigate the characteristics of patients with preadolescent- and adolescent-onset immunoglobulin A vasculitis (IgAV) and to determine whether age affects IgAV outcomes in adolescents. METHODS Demographic, clinical, and laboratory data of 333 patients diagnosed with IgAV at the Department of Pediatric Rheumatology, University of Health Sciences, Ankara City Hospital, were evaluated retrospectively. The patients were classified into two groups: preadolescents (<10 years) and adolescents (10-19 years). Subgroup analyses were also performed by grouping the adolescent patients into early, middle, and late adolescent groups. RESULTS Of the 333 patients, 219 (65.8%) and 114 (34.2%) were preadolescents and adolescents. Palpable purpura, renal, joint, and gastrointestinal (GI) tract involvement were detected in 333 (100%), 78 (23.4%), 79 (23.7%), and 124 (37.2%) patients, respectively; testicular involvement was observed in 25 (13.3%) of 187 male patients. The frequency of renal involvement was significantly higher in the adolescent group than in the preadolescent group at the time of diagnosis (p = 0.030). Notably, joint involvement was significantly higher in the adolescent group (p = 0.001). The need for aggressive therapy was significantly higher in the adolescent group than in the preadolescent group (p = 0.003). There was no significant difference in clinical data, demographic characteristics, and laboratory findings between the adolescent subgroups (p > 0.05). CONCLUSIONS Immunoglobulin A vasculitis can occur at any age but the disease prognosis appears to worsen with age. The present study reported that joint involvement, kidney involvement, and the need for more aggressive treatment were higher in the adolescent group than in the preadolescent group.

Multisystem inflammatory syndrome in children: clinical presentation, management, and short- and long-term outcomes. Clin Rheumatol 2022; 41:3807-3816. [PMID: 36018446 PMCID: PMC9411826 DOI: 10.1007/s10067-022-06350-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 08/16/2022] [Accepted: 08/22/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVE In this study, it was aimed to evaluate the demographic, clinical and laboratory characteristics of MIS-C patients in our hospital, to share our treatment approach, and to assess the outcomes of short- and long-term follow-up. METHODS MIS-C patients who were admitted and treated in our hospital between July 2020 and July 2021 were evaluated. Demographic, clinical, laboratory, and follow-up data were collected from patient records retrospectively. RESULTS A total of 123 patients with MIS-C (median age, 9.6 years) were included the study. Nineteen (15.4%) were mild, 56 (45.6%) were moderate, and 48 (39%) were severe MIS-C. High CRP, ferritin, pro-BNP, troponin, IL-6, and D-dimer values were found in proportion to the severity of the disease (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.005, p < 0.001), respectively. Two (1.6%) patients died. The mean follow-up period was 7.8 months. Valve failure, left ventricular dysfunction/hypertrophy, coronary involvement, and pericardial effusion were the most common cardiac pathologies in the short- and long-term follow-up of the patients. In the long-term follow-up, the most common reasons for admission to the hospital were recurrent abdominal pain (14.2%), cardiac findings (14.2%), pulmonary symptoms (8%), fever (7.1%), neuropsychiatric findings (6.2%) and hypertension (3.5%). Neuropsychiatric abnormalities were observed significantly more common in severe MIS-C patients at follow-up (p = 0.016). In the follow-up, 6.2% of the patients required recurrent hospitalization. CONCLUSION MIS-C is a serious and life-threatening disease, according to short-term outcomes. In addition to the cardiac findings of patients with MIS-C, long-term outcomes such as neuropsychiatric findings, persistent gastrointestinal symptoms, fever and pulmonary symptoms should be monitored. Key Points • In MIS-C patients, attention should be paid not only to cardiac findings, but also to symptoms related to other systems. • Patients should be followed up in terms of neuropsychiatric findings, persistent gastrointestinal symptoms, fever and pulmonary symptoms that may occur during follow-up.

Abstract
BACKGROUND To determine the interval between disease onset and admission to pediatric rheumatology clinic of patients with juvenile idiopathic arthritis (JIA) and, to identify the factors that affect the admission time (AT) to rheumatology center. METHODS We designed a retrospective observational study in children with JIA. The study variables were age, gender, JIA subtype, acute phase reactants (APR), disease activity scales, presence of a pediatric rheumatologist, and distance to a pediatric rheumatology center. Outcome parameter was the duration between onset of symptoms and first visit of rheumatologist. The parameters were evaluated with variance analysis and regression models. RESULTS 198 patients (female:120 (60.6%)) were included. There were 112 (56.5%) patients in oligo-articular JIA, 27 (13.6%) in rheumatoid factor negative poly-articular JIA, 22 (11.1%) in enthesitis related arthritis (ERA), 29 (14.6%) in systemic-JIA, 4 (2%) in rheumatoid factor positive poly-JIA, two patients each in undifferentiated and psoriatic arthritis. The median AT in the systemic-JIA and other groups was 16 (IQR 10.5-27.5) and 71 (IQR 33.5-211) days, respectively. There was a significantly longer AT in the ERA group than others (p=0.005). We found a correlation between longer AT and older age, low back pain, enthesitis, and low erythrocyte sedimentation rate (ESR). In the multivariate analysis, only low ESR and enthesitis contributed an increase in AT [OR 2.05 (1.07-3.93), 6.22 (1.29-29.99)]. CONCLUSIONS The older age, low back pain, enthesitis and low ESR contribute to the late AT. JIA requires high suspicion in children with poorly defined findings and low APR.

Abstract
A 16-year-old girl was admitted to the hospital for the absence of a menstrual bleeding over 10 mounts. She has had regular menstrual periods since she was 13 years old and no history of systemic disease. Laboratory tests showed low estrogen (<11.8 ng/L, range 16–238 ng/L), elevated FSH (follicle stimulating hormone) (138.3 U/L), low AMH (anti-Mullerian hormone) (<0.01 µg/L), normal prolactin (7 μg/L), and thyroid hormone levels (TSH: 1.5 mU/L). The ovaries were prepubertal in size and diagnosed with primer ovarian failure. ANA titers, antiphospholipid antibody, and direct coombs were positive. Microscopic hematuria and nephritic proteinuria (34 mg/m2/hour) were also detected and renal biopsy was revealed stage 3–5 lupus nephritis. Premature ovarian failure is an extremely rare disease in childhood. When POF is detected in the adolescent, it is important to investigate the etiology. In this way, it may be possible to diagnose diseases with high morbidity and mortality that may cause POF.

Abstract
OBJECTIVES The aims of this study were to evaluate the role of biological agents in the treatment of severe multisystem inflammatory syndrome in children (MIS-C) and to assess the current application, outcomes, and adverse effects in patients who are followed up in a pediatric intensive care unit (PICU). PATIENTS AND METHODS This observational, descriptive, medical records review study was performed on patients with MIS-C admitted to the PICU between September 1 and November 1, 2020. Through medical records review, we confirmed that patients were positive for current or recent SARS-CoV-2 infection or for COVID-19 exposure history within the 4 weeks before the onset of symptoms. RESULTS A total of 33 patients with severe MIS-C were included (21 male) with a median age of 9 years. The most common signs and symptoms during disease course were fever (100%) and abdominal pain (75.5%). Clinical features of 63.6% patients were consistent with Kawasaki disease/Kawasaki disease shock syndrome, and 36.4% were consistent with secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome. Myocardial dysfunction and/or coronary artery abnormalities were detected in 18 patients during the PICU stay. Intravenous immunoglobulin and corticosteroids were given to 33 patients. Anakinra was administered to 23 patients (69.6%). There was a significant increase in lymphocyte and platelet counts and a significant decrease in ferritin, B-type natriuretic peptide, and troponin levels at the end of the first week of treatment in patients who were given biological therapy. Two patients were switched to tocilizumab because of an insufficient response to anakinra. The mortality rate of MIS-C patients admitted in PICU was 6.0%. CONCLUSIONS Management of systemic inflammation and shock is important to decrease mortality and the development of persistent cardiac dysfunction in MIS-C. The aggressive treatment approach, including biological agents, may be required in patients with severe symptoms and cardiac dysfunction.

Delta neutrophil index and C-reactive protein: a potential diagnostic marker of multisystem inflammatory syndrome in children (MIS-C) with COVID-19. Eur J Pediatr 2022; 181:775-781. [PMID: 34647164 PMCID: PMC8514280 DOI: 10.1007/s00431-021-04281-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 09/02/2021] [Accepted: 10/03/2021] [Indexed: 12/19/2022]
Abstract
Multisystem inflammatory syndrome in children (MIS-C) is a life-threatening hyperinflammation syndrome emerging after COVID-19. The serum delta neutrophil index (DNI) reflects the fraction of circulating immature granulocytes and is evaluated in infection and inflammation. The aim of this study is to evaluate the usefulness of DNI as a diagnostic marker in patients with MIS-C and to assess its role in determining the severity of MIS-C. This retrospective, observational study included 83 patients with MIS-C and 113 patients with COVID-19, and 102 healthy controls. C-reactive protein (CRP), the absolute neutrophil count (ANC), absolute lymphocyte count (ALC), DNI, and the platelet count were recorded. The DNI levels were 4.60 ± 5.70% in the MIS C group, 0.30 ± 0.99% in the COVID group, and 0.20 ± 0.56% in the control group (p < 0.001). According to the severity of MIS-C, the DNI level was found to be 1.22% in mild MIS-C, 4.3% in moderate MIS-C, and 5.7% in severe MIS-C. There was a statistically significant correlation between DNI levels and the severity of MIS-C. The cutoff value of DNI for predicting MIS-C was 0.45%. In the analysis of the diagnostic performance of DNI compared with CRP, ANC, ALC and platelet counts, sensitivity, specificity, positive predictive value, and negative predictive value were found to be 79.5%, 97.1%, 95.7%, and 85.3%, respectively.Conclusions: The delta neutrophil index was identified as a diagnostic marker for MIS-C such as ANC, ALC, platelet count, and CRP. DNI levels in hemogram analysis may guide clinicians in determining the diagnosis and severity of MIS-C. What is Known: • Although CRP, sedimentation, ALC, ANC, platelet count, sodium, and albumin are used as first step tests, there is no specific laboratory marker used in the diagnosis of MIS C. • The serum delta neutrophil index (DNI) reflects the fraction of circulating immature granulocytes and is elevated in infection and inflammation. What is New: • DNI is a promising and easily accessible marker that can be used with other markers in the diagnosis and determines the severity of MIS C. • DNI is an easily accessible, inexpensive, and dynamic marker and its levels in simple hemogram analysis will guide pediatricians in determining the diagnosis and severity in MIS C.

Abstract
BACKGROUND Chronic non-bacterial osteomyelitis is a chronic sterile inflammatory bone condition. We aimed to describe patients' clinical and radiographic findings and to evaluate their response to therapy and their quality of life. METHODS This cross-sectional study included 18 patients from a single center in Turkey whose clinical, radiological features, and outcomes were reviewed retrospectively. The quality of the patients' lives after treatment was compared with healthy controls using the Pediatric Quality of Life Inventory 4.0. RESULTS The median age of disease onset was 12 years (IQR 10-14 years) and 11 (61.1%) patients were male. The median follow-up duration was 15 months (IQR 12-22 months). The persistent form of chronic non-bacterial osteomyelitis was the most common pattern in 15 (83.3%) patients and a recurrent pattern was defined in three (16.7%) patients. The lesions were multifocal in all patients and 15 (83.3%) patients had symmetric distribution in whole-body magnetic resonance imaging. The most common sites of arthritis were the knee and sacroiliac joints. Methotrexate was used in 16 (88.9%) patients as first-line therapy. However, some patients were unresponsive to the first-line therapy and needed tumor necrosis factor-α inhibitors (55.6%) and bisphosphonates (16.7%). We observed remission in only four (22.2%) patients, and three (16.7%) patients were unresponsive. The patients had a significantly poorer quality of life than controls (P = 0.005). CONCLUSIONS Chronic non-bacterial osteomyelitis is an insidious disease that requires detailed analysis for diagnosis and whole-body magnetic resonance imaging is an effective tool for its diagnosis. Despite the advanced treatment, patients with chronic non-bacterial osteomyelitis have a poor quality of life.

Abstract
OBJECTIVES Juvenile Behçet's disease is a rare and severe disease of childhood characterized by a chronic inflammatory vasculitis. The aim of the present study is reporting demographic, clinical and therapeutic outcomes of juvenile Behçet's disease in a tertiary center. METHODS The retrospective study included patients who were diagnosed Behçet's disease before 16 years. The demographic and clinical features, and diagnostic and therapeutic strategies of patients were recorded. RESULTS Seventy-two patients with jBD were included in this study; 32 were male (44.4%). Thirty (41.7%) patients had BD cases in their family. We observed oral ulceration (100%), genital ulceration (68.1%), joint involvement (36.1%) and cutaneous manifestations (34.7%) as the most common clinical findings, respectively. As severe organ involvements, 20.8% ocular, 18.1% vascular and 15.3% neurologic pathologies were seen. All patients had colchicine. Corticosteroid (20.8%) was used to treat severe cases and acute attacks. Azathioprine (23.6%) was the main immunosuppressive agent and cyclophosphamide (8.3%) was applied initially for life-threatening conditions with pulse methylprednisolone. CONCLUSION In this cohort, the prevalence of genital ulceration and family history was high, and we observed less ocular involvement, a few permanent neurological morbidities and no death. Key Points • In the present study, there were acceptable permanent neurological involvements as morbidity and no mortality. • It is important noticing and managing jBD in early phase in order to prevent the devastating results. • The awareness of jBD provides timely treatment of patients. • The positivity of family history and HLA B51 should alert the clinician about the incomplete cases.

Abstract
OBJECTIVES The aims of this study were to describe the clinical features, comorbidities and outcome of systemic childhood polyarteritis nodosa (PAN) and to evaluate PAN-like diseases in differential diagnosis. METHODS The study group consisted of patients who were diagnosed as PAN in a referral center in Turkey. The files of all patients were reviewed retrospectively. Disease activity was evaluated with pediatric vasculitis activity score (PVAS). RESULTS A total of 19 (13 boys/six girls) patients were enrolled in the study. The mean age of patients was 10.37 ± 3.6 years. The mean duration of follow-up was 5.73 ± 3.74 years. Eight patients (42.1%) were also diagnosed with familial Mediterranean fever (FMF). The cutaneous involvement was higher in patients with PAN than those with FMF-associated PAN (p = .03). The median (min-max) PVAS at diagnosis was 5 (3-7). There was no correlation between PVAS scores at the time of diagnosis and age, clinical findings and relapse. CECR1 mutation was detected in one patient leading to deficiency of adenosine deaminase 2. CONCLUSION The clinical presentation is variable in children with PAN. PAN-like diseases characterized by necrotizing vasculitis should be considered. The possibility of FMF should be kept in mind if inflammation cannot be controlled.

Abstract
AIMS Recently, multisystem inflammatory syndrome in children (MIS-C) has been recognized in association with coronavirus disease 2019 as a cytokine storm syndrome. MIS-C presents with symptoms similar to Kawasaki disease and macrophage activation syndrome (MAS). We aimed to better understand this cytokine storm syndrome by comparing the initial laboratory findings of MIS-C and MAS. METHODS Patients who were diagnosed with MAS due to systemic juvenile idiopathic arthritis in our clinic between March 2002 and November 2020 and with MIS-C between 20 September and 20 October 2020 were enrolled into the study. The medical files of all patients were reviewed retrospectively. RESULTS A total of 13 MAS (9 boys, 4 girls) and 26 MIS-C (16 boys,10 girls) patients were included in the study. Hemoglobin, absolute neutrophil and lymphocyte counts, C-reactive protein (CRP), ferritin, fibrinogen and lactate dehydrogenase (LDH) levels showed significant differences between the two groups (P < 0.05). Patients with MAS had lower hemoglobin (10.10 g/dL) and fibrinogen (2.72 g/dL), but higher ferritin (17 863 mg/dL) and LDH (890.61 U/L) at the time of diagnosis. Patients with MIS-C had higher absolute neutrophil count (12 180/mm3 ) and CRP (194.23 mg/dL) values, but lower absolute lymphocyte count (1140/mm3 ) at the time of diagnosis. Left ventricle ejection fraction was significantly lower in the MIS-C group in echocardiographic evaluation (P < 0.001). CONCLUSION Ferritin, hemoglobin, LDH, and fibrinogen levels were significantly changed in MAS compared with MIS-C. However, patients with MIS-C have more severe signs than MAS, such as cardiac involvement.

Abstract
OBJECTIVE The aim of this study is to describe clinical features of patients with oligoarticular juvenile idiopathic arthritis (JIA) who achieved inactive disease at 3rd month and also to determine the predictors of relapse and extended course. METHODS In the cohort study, 88 patients with oligoarticular JIA were retrospectively analyzed. The demographic data, clinical features, medications, relapse rates were recorded. Juvenile Arthritis Disease Activity Score (JADAS) and American College of Rheumatology Pediatric criteria were used to measure disease activity and treatment response at 3, 6 and 12 months. RESULTS Fifty-nine (67%) patients were females and the mean age at diagnosis was 7.9 ± 4.3 years. The odds of achieving inactive disease (JADAS ≤1) at 3rd month were increased by a lower JADAS27 score at admission. Forty-one (48.8%) of 84 patients relapsed. Ankle involvement at onset, high JADAS27 score at admission, increased ESR at admission and presence of synovial hypertrophy in imaging were risk factors for occurrence of relapse. CONCLUSION Our results show that a significant proportion of oligoarticular JIA patients relapse after inactive period. JADAS is a useful tool to guide the treatment decisions of patients who may be at risk of high disease activity and relapse.

Performance of the new Eurofever/PRINTO classification criteria in Familial Mediterranean fever patients with a single exon 10 mutation in childhood. Rheumatol Int 2020; 41:95-101. [PMID: 33006008 DOI: 10.1007/s00296-020-04709-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 09/18/2020] [Indexed: 10/23/2022]
Abstract
The diagnosis of Familial Mediterranean fever (FMF) based on clinical findings supported by genetic mutation. Recently, the new Eurofever/PRINTO classification criteria including genetic analysis were established. The aim of this study is to evaluate the performance of the new criteria in FMF patients with a single exon 10 mutation in childhood. The study group consisted of FMF patients who had a single exon 10 mutation in a referral center in Turkey. Patients with periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome were included as a control group. The medical charts of all patients were reviewed retrospectively. A total of 106 FMF patients (59 boys) were enrolled in the study group. The median age at first symptom was 5; the median age at diagnosis was 7 years. The mean follow-up was 33 ± 35.4 months. Majority of the patients (n = 58, 54.7%) had heterozygous M694V, 16 (15%) patients had M694V/E148Q and 13 (13.8%) patients had heterozygous M680I mutation. The sensitivity of the Yalcinkaya-Ozen criteria was 98.1% and it was 97.1% for the Eurofever/PRINTO classification criteria. The specificity of the new Eurofever/PRINTO classification criteria was 96.7% and it was 74.1% for the Yalcinkaya-Ozen criteria. The new Eurofever/PRINTO classification criteria have a good sensitivity as the Yalcinkaya-Ozen criteria in patients with a single exon 10 mutation. Additionaly, the new criteria have better specificity. It should be useful to apply the clinical only criteria where the carrier rate is high.
