RESUMO
OBJECTIVES: Familial Mediterranean fever (FMF) is characterized by febrile polyserositis attacks. Menstruation could be a trigger for attacks. We aimed to analyze the features of adolescent FMF patients with menstruation-associated attacks and propose a management algorithm. METHODS: All female FMF patients who had menarche and visited the Pediatric Rheumatology Unit between January-December 2022, were included into this study. Demographics, general characteristics, and the features of menstrual cycle and FMF attacks were noted. RESULTS: A total of 151 female FMF patients were included. Thirty-five (23.2%) had menstruation-associated attacks. Fever and arthritis were less frequent during the menstruation-associated attacks than the attacks not associated with menstruation in these patients (65.7% vs 88.6%, p= 0.01 and 2.9% vs 20%, p= 0.04; respectively). Patients with menstruation-associated FMF attacks were younger at symptom onset and diagnosis (2.5 vs 5 years, p= 0.004 and 4 vs 7 years, p= 0.01; respectively), had a higher rate of dysmenorrhea (74.3% vs 38.8%, p< 0.001, respectively) and higher pre- and post-menarche attack frequency (4 vs 2 and 10 vs 0, respectively; p< 0.001 for both) than patients whose attacks were not associated with menstruation. The interventions for menstruation-associated attacks included initiating colchicine, increasing the dose of colchicine, switching from coated to compressed colchicine tablets or anti-interleukin 1 drugs, and on-demand non-steroidal anti-inflammatory drugs, on-demand glucocorticoids, and on-demand anakinra. On-demand therapies were beneficial in controlling menstruation-associated attacks. CONCLUSIONS: This is the largest cohort of adolescent FMF patients with menstruation-associated attacks. Severe FMF may cause tendency to this association. On-demand therapies could be preferred in the management.
RESUMO
OBJECTIVES: The transition of adolescents and young adults (AYAs) from pediatric to adult-oriented healthcare may be affected by many factors, including the personal and cultural settings. We aimed to analyze the transition readiness and the factors affecting the transition success in rheumatology. METHODS: Patients older than 12 years were included in this prospective study. All filled out the Transition Readiness Assessment Questionnaire (TRAQ) 5.0. AYAs were phone-interviewed after their transfer to adult-oriented healthcare. Drug adherence was evaluated with 4-item Morisky Medication Adherence Scale (MMAS-4). AYAs rated their transitional care experience with visual analogue scale (VAS 0-10; 0, the worst; 10, the best). RESULTS: A total of 504 TRAQs were filled out by 406 patients (F/M = 1.5). The total TRAQ score was positively correlated with age and higher in the forms filled out by girls than boys (4.2 vs 4.0, respectively; p= 0.005). The transition was successful for 78 (83.9%) out of 93 patients transferred to adult-oriented healthcare. The VAS for the transition process was lower and the post-transfer MMAS-4 score was worse (8 vs 9, p= 0.030 and 3 vs 4, p= 0.020; respectively) in patients whose transition was not successful when compared with the successfully-transitioned ones. The best-performing TRAQ cut-off value was >4.0 for predicting transfer readiness in rheumatology. CONCLUSION: A TRAQ score of > 4 could be used while deciding about the transfer readiness of AYAs in rheumatology. Improving the AYAs' experience of the transition process and closely monitoring medication adherence during transition are essential for a successful transition.
RESUMO
OBJECTIVES: The aim of this study is to investigate the effect of anti-interleukin (IL)-1/-6 biologics on systemic juvenile idiopathic arthritis (sJIA)-associated macrophage activation syndrome (MAS). METHODS: Demographic, clinical, and laboratory data of patients followed up with a diagnosis of sJIA-associated MAS assessed from sixteen pediatric rheumatology centers across the country. The clinical and laboratory features of MAS developing while on biological drugs were compared with those without this treatment. RESULTS: One hundred and sixty-two patients were included in the study. 45 of the MAS events were detected under the effect of anti-IL-1/-6 biologics, while the patients experiencing the remaining 155 events have not received biological treatment in the last three months. Platelet count [128 (72-232) vs 199 (130-371) 109/l], ferritin level on admission [1107 (676-2050) vs 2863 (1193-9562) ng/ml], C-reactive protein level [15.4 (2.9-56) vs 90 (32-160) mg/l], erythrocyte sedimentation rate [13 (3-36) vs 43.5 (13-77) mm/h] and fever duration [5 (4-7.5) vs 10 (7-14.3) days] were found lower in the group under the impact of anti-IL-1/-6 biologics. Among patients treated with biologics, 26.6% did not meet the published 2016 MAS classification criteria at presentation. The rates of hepatomegaly and splenomegaly were relatively lower in the canakinumab-treated group when compared with those receiving other biologicals or to patients, not on biologicals. CONCLUSION: Anti-IL-1/-6 therapies can mask the clinical and laboratory features of MAS, and proposed guidelines for MAS classification criteria may not be met.
RESUMO
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
BACKGROUND: Drug-induced lupus erythematosus (DILE) is the development of lupus-like syndrome following a drug exposure. DILE has been reported less frequently among children than adults. METHODS: In this study, we present four children with DILE and similar published cases through a systematic literature review. RESULTS: We report four children (three girls and one boy) who developed DILE associated with the use of topiramate, doxycycline, etanercept, and ethosuximide. Three of them were positive for anti-histone antibodies. In all patients, the drug was discontinued and symptoms resolved completely. The literature review revealed 48 articles describing 61 children with DILE. In the evaluation of 65 patients (our 4 patients and 61 patients from the literature), the most frequently reported drugs associated with DILE were ethosuximide (n = 13) and minocycline (n = 12). Fever (n = 33), arthralgia (n = 31), rash (n = 30), and arthritis (n = 29) were the most common clinical manifestations. Antinuclear antibody (ANA) was positive in 93.5% of patients and anti-histone antibodies were detected in 72.2% of the patients. As for treatment, the responsible drug was discontinued in all patients, and corticosteroids were initiated in 53.3%. Improvement was achieved in 92.0% of patients. CONCLUSION: For children presenting with SLE features, proper drug history is crucial since DILE may be more frequent than anticipated. An association of the relevant drug with the symptoms, and resolution of symptoms on drug withdrawal provides evidence for the diagnosis of DILE.

OBJECTIVE: In this study, we aimed to evaluate the characteristics of pediatric rhupus patients including all the related series in the literature. METHODS: Thirty pediatric patients with rhupus syndrome from 12 different centers in Turkey were included in this study. The literature was also reviewed for pediatric patients with rhupus syndrome. RESULTS: The most prominent phenotype of these 30 patients was juvenile idiopathic arthritis (JIA) (60%) at the disease onset and SLE (73.3%) at the last visit. Major SLE-related organ involvements were skin (80%), hematological system (53.3%), and kidney (23.3%). Arthritis was polyarticular (73.3%), asymmetric (66.7%), and erosive (53.3%) in most patients. Hydroxychloroquine (100%), glucocorticoids (86.7%), and mycophenolate mofetil (46.7%) were mostly used for SLE, while glucocorticoids (76.6%), methotrexate (73.3%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (57.6%) were mainly preferred for JIA. Our literature search revealed 20 pediatric patients with rhupus syndrome (75% were RF positive). The most prominent phenotype was JIA (91.7%) at the disease onset and SLE (63.6%) at the last visit. Major SLE-related organ involvements were skin (66.7%), hematological system (58.3%), and kidney (58.3%). Arthritis was polyarticular (77.8%), asymmetric (63.6%), and erosive (83.3%) in most patients. Glucocorticoid (100%), hydroxychloroquine (76.9%), and azathioprine (46.2%) were mostly used for SLE, while methotrexate (76.9%) and NSAIDs (46.2%) were mainly preferred for the JIA phenotype. CONCLUSION: Our study is the largest cohort in the literature evaluating pediatric rhupus cases. Most of the pediatric patients had polyarticular, asymmetric, and erosive arthritis, as well as organ involvements associated with SLE, including the skin, hematological system, and kidney.

OBJECTIVE: We aimed to delineate the distinctive characteristics that aid in distinguishing between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) with KD-like manifestations during the pandemic. MATERIALS AND METHODS: We evaluated KD patients and MIS-C patients with KD-like symptoms admitted during the pandemic (between January 2021 and December 2022). RESULTS: Thirty-three MIS-C patients and 15 KD patients were included. Kawasaki disease patients were younger than MIS-C patients (3.4 vs. 7.6 years). Rash (P = .044, 100% vs. 75.7%), oral mucosal changes (P = .044, 100% vs. 75.7%), and cervical lymphadenopathy (P = .001, 93.3% vs. 42.4%) were more common in KD. Multisystem inflammatory syndrome in children: patients had more hypotension (P = .002, 45.4% vs. 0), gastrointestinal (P .001, 72.7% vs. 13.3%), and respiratory symptoms (P = .044, 24.2% vs. 0). Multisystem inflammatory syndrome in children patients also had low lymphocyte and thrombocyte counts and elevated levels of d-dimer, ferritin, and cardiac parameters, unlike KD patients. Multisystem inflammatory syndrome in children patients exhibited a notable reduction in left ventricular systolic function in echocardiography. Another significant difference with regard to management was the anakinra treatment, which was prescribed for MIS-C patients. CONCLUSION: Although MIS-C patients might display a clinical resemblance to KD, several features could help differentiate between MIS-C and classical KD. Specific clinical (hypotension, gastrointestinal, and respiratory symptoms) and laboratory (low lymphocyte and thrombocyte counts with higher C-reactive protein, ferritin, d-dimer, and cardiac parameters) features are characteristic of MIS-C. In addition, divergence in management strategies is evident between the 2 diseases, as biologic drugs were more prevalently employed in MIS-C patients than in classical KD patients.
RESUMO
OBJECTIVE: Our study was designed to investigate the reasons for starting the conventional disease-modifying anti-rheumatic drugs (DMARDs) and the variables that impact the response to DMARD treatment in oligoarticular juvenile idiopathic arthritis (JIA) patients. METHODS: Oligoarticular JIA patients (n = 187) were categorized into two groups: Group A consisted of patients who achieved remission with DMARD, and Group B comprised those who did not respond to DMARD therapy. RESULTS: DMARDs were initiated for various reasons: 68 (36.4%) due to active disease despite nonsteroidal anti-inflammatory drugs (± intra-articular corticosteroid) treatment, 59 (31.6%) due to uveitis, 49 (26.2%) due to extended oligoarticular JIA, and 11 (5.9%) due to inflammatory bowel disease. One hundred twenty-three patients (65.8%) achieved remission with DMARDs (Group A), while 64 patients (34.2%) did not respond to DMARD therapy (Group B). In Group B, patients had higher C-reactive protein (CRP) levels as well as higher Juvenile Idiopathic Arthritis Disease Activity Scores-71 (JADAS-71) at diagnosis (both p < 0.001). Moreover, extended oligoarticular JIA subtype (p = 0.017) and involvement of small joints at diagnosis (p = 0.043) were more prevalent among these patients. Group A exhibited a higher frequency of antinuclear antibody positivity (p = 0.014). Elevated CRP levels (> 1.1 mg/dL) (OR 1.308, 95% CI 1.203-3.574; p < 0.001) and high JADAS-71 at diagnosis (> 15.8) (OR 1.659, 95% CI 1.179-2.941; p < 0.001) were associated with DMARD resistance. CONCLUSION: Elevated CRP and high JADAS-71 at diagnosis were the main factors associated with DMARD resistance in oligoarticular JIA. Prospective long-term studies may help verify the role of these factors associated with DMARD resistance in oligoarticular JIA. Key Points ⢠Conventional DMARDs were most commonly started due to active disease despite NSAID (± intra-articular corticosteroids). ⢠Remission was achieved with DMARD in 65.8% of oligoarticular JIA patients. ⢠Elevated CRP and high JADAS-71 at diagnosis were associated with DMARD resistance.

BACKGROUND: In this study, we aimed to evaluate choices and changes of biologic drugs in juvenile idiopathic arthritis (JIA) patients according to disease subtypes. METHODS: We retrospectively analyzed JIA patients who received biologic treatment between January 2004 and July 2022. RESULTS: Of 294 JIA patients, 80 (27.2%) had systemic JIA, 68 (23.1%) had oligoarticular JIA, 61 (20.7%) had polyarticular JIA, 79 (26.9%) had enthesitis-associated arthritis (ERA), and six (2.1%) had psoriatic arthritis (PsA). Anakinra (n=66, 82.5%) was the most commonly preferred first line biologic in systemic JIA. Etanercept was the most frequently used biologic drug in patients with ERA (n=69, 87.3%), oligoarticular (n=37, 54.4%) and polyarticular JIA (n=43, 70.5%). Adalimumab was used as a first-line biologic drug in all PsA patients (n=6, 100%). One hundred-fourteen patients (38.8%) were switched to second-line and 29 (9.9%) to third-line biologic drugs. While the most common reason for switching to a second-line biologic was difficulty in usage of daily injections (n=37, 60.6%) in systemic JIA patients, it was an inadequate response to first biologics in non-systemic JIA patients (n=42, 79.2%). Side effects were detected in only seven patients (2.4%) during the follow-up. CONCLUSION: In this study, we revealed the biologic drug usage and switch strategies in our JIA patients. Good responses were obtained in most of our patients with a reliable profile. However, studies on larger patient groups are needed to clarify these results.

The activation of the pyrin inflammasome represents a highly intriguing mechanism employed by the innate immune system to effectively counteract pathogenic agents. Despite its key role in innate immunity, pyrin has also garnered significant attention due to its association with a range of autoinflammatory diseases (AIDs) including familial Mediterranean fever caused by disruption of the MEFV gene, or in other genes involved in its complex regulation mechanisms. Pyrin activation is strictly dependent on homeostasis-altering molecular processes, mostly consisting of the disruption of the small Ras Homolog Family Member A (RhoA) GTPases by pathogen toxins. The downstream pathways are regulated by the phosphorylation of specific pyrin residues by the kinases PKN1/2 and the binding of the chaperone 14-3-3. Furthermore, a key role in pyrin activation is played by the cytoskeleton and gasdermin D, which is responsible for membrane pores in the context of pyroptosis. In addition, recent evidence has highlighted the role of steroid hormone catabolites and alarmins S100A8/A9 and S100A12 in pyrin-dependent inflammation. The aim of this article is to offer a comprehensive overview of the most recent evidence on the pyrin inflammasome and its molecular pathways to better understand the pathogenesis behind the significant group of pyrin-related AIDs.

La púrpura de Schonlein-Henoch (PSH) es la vasculitis más frecuente en los niños. Los procesos vasculíticos pueden afectar el pulmón. Si bien la hemorragia alveolar difusa puede considerarse una de las manifestaciones de la PSH, no es un cuadro frecuente. En este artículo presentamos el caso de una niña de 10 años con nefritis por PSH que sufrió hemorragia pulmonar. La paciente recibió un tratamiento satisfactorio con metilprednisolona intravenosa. La revisión de las publicaciones reveló que la edad temprana puede influir de manera positiva en el pronóstico, y que los inmunosupresores y el tratamiento complementario son fundamentales.
Henoch-Schonlein purpura (HSP) is the most common vasculitis in children. Vasculitic processes can involve the lung. Although diffuse alveolar hemorrhage may be seen as one of the manifestation of HSP, it is not a frequent presentation. Here we reported the case of a 10-year-old girl with HSP nephritis who developed pulmonary hemorrhage. The patient was treated successfully with intravenous methylprednisolone. A review of the literature revealed that young age may be a good prognostic sign and that immunosuppressive drugs and supportive management are essential in the treatment.
