RESUMEN
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.
RESUMEN
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.
RESUMEN
OBJECTIVES: Juvenile Idiopathic Arthritis (JIA) is the most common rheumatic disease of childhood; the pathogenesis is associated with T cell activation. T cell activation can be counter-balanced by signals generated by inhibitory receptors (IRs) such as CTLA-4, PD-1, LAG-3, and TIM-3. Here, we identify the role of IRs in the pathogenesis of different JIA subtypes. METHODS: In total, we included 67 oligoarticular JIA, 12 IgM-RF negative polyarticular JIA, 17 enthesitis related arthritis, 11 systemic JIA patients and 10 healthy controls. We collected plasma (and synovial fluid) samples from the patients either at the onset or during a flare of their disease. We measured the soluble levels of co-IRs (IL-2Rα, 4-1BB, CD86, TGF-ß1, CTLA-4, PD-L1, PD-1, TIM-3, LAG- 3, Galectin-9) by cytometric bead array kits and their cellular expression (PD-1, CTLA-4, TIM-3, LAG-3) by flow cytometry. We compared the plasma levels and cellular expressions of different co-IRs within different JIA subgroups. RESULTS: The polyarticular-JIA group was different from the three other examined JIA subgroups, having higher levels of plasma sCTLA-4(p< 0.001), sPD-1(p< 0.05), and s4-1BB(p< 0.05) when compared with the other JIA subgroups and healthy controls. We analyzed the cellular surface expression of different co-IRs on the PBMCs of different JIA subtypes. Similar to plasma levels, both the percentage(p< 0.05) and the MFI (mean fluorescence intensity) (p< 0.01) of CTLA4 expression were higher in the poly-JIA subgroup. CONCLUSION: This is the first report studying the expression profile of different co-IRs in different subtypes of JIA. Polyarticular JIA patients had a different co-IR profile, having more CTLA-4, PD-1 and 4-1BB in their plasma than the other subtypes of JIA.
RESUMEN
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.
