Takayasu arteritis with an initial presentation of chronic monoarthritis mimicking oligoarticular juvenile idiopathic arthritis

Patients with Takayasu arteritis (TA) generally present with non-specific symptoms that, if unrecognized and untreated, may develop vessel stenosis and/or aneurysm. There is limited data regarding chronic monoarthritis as the initial presentation in children with TA. We report a 6-yearold girl diagnosed and treated as oligoarticular juvenile idiopathic arthritis (JIA). She later developed stroke with malignant hypertension and was definitively diagnosed with TA. She additionally developed proteinuria secondary to focal segmental glomerulosclerosis. This is the report of a patient with chronic monoarthritis mimicking oligoarticular JIA which chronic monoarthritis was the presentation of TA. Since JIA is a diagnosis of exclusion, any atypical features of oligoarticular JIA should illuminate the possibility of an alternative diagnosis. Our literature review focused on musculoskeletal presentations of children with TA

Outcomes in children with rheumatic diseases following COVID-19 vaccination and infection: data from a large two-center cohort study in Thailand

IntroductionVaccination against coronavirus disease 2019 (COVID-19) is effective in protecting patients from severe COVID-19 infection. Disease flare-up following immunization in children with rheumatic disorders may result in patient reluctance to receive the vaccine. Underlying rheumatic diseases or the use of immunosuppressive drugs may influence the outcomes of COVID-19 vaccination and infection. We aimed to describe outcomes in children with rheumatic diseases following COVID-19 immunization and infection.MethodsThis retrospective study was performed at two large academic centers in Thailand. During the COVID-19 pandemic, all patients were routinely queried about COVID-19-related conditions. We included patients with rheumatic diseases aged <18 years who received at least one dose of a COVID-19 vaccine or had a history of COVID-19 infection with more than 6 months of recorded follow-up after the last vaccine dose or COVID-19 illness. Demographic information and data on clinical symptoms, disease activity, treatment, outcomes, and COVID-19 vaccination and infection were collected.ResultsA total of 479 patients were included. Most (229; 47.81%) patients had juvenile idiopathic arthritis, followed by connective tissue diseases (189; 39.46%), vasculitis syndromes (42; 8.76%), and other rheumatic diseases (19; 3.97%). Approximately 90% of patients received at least one dose of COVID-19 vaccination, and half of the patients had COVID-19 infection. Among patients, 10.72% and 3.27% developed a flare after COVID-19 vaccination and COVID-19 illness, respectively. Flare severity after COVID immunization and infection was mainly mild to moderate. The predictor of flare after COVID-19 vaccination was the use of prednisolone ≥10 mg/day before vaccination (hazard ratio: 2.04, 95% confidence interval: 1.05–3.97, p = 0.037). Inactive disease before receiving the COVID-19 vaccination was a predictor of inactive status after a flare (hazard ratio: 2.95, 95% confidence interval: 1.04–8.40; p = 0.043). Overall, 3.36% and 1.61% of patients experienced a new onset of rheumatic disease after receiving the COVID-19 vaccine and after COVID-19 infection, respectively.ConclusionThe COVID-19 vaccine is recommended for children with rheumatic disease, particularly those who are in stable condition. After COVID-19 vaccination, patients—especially those with active disease before vaccination or those receiving concurrent prednisolone doses of ≥10 mg/day—should be closely monitored

Acute epiglottitis as the initial presentation of pediatric Systemic Lupus Erythematosus

We report a case of a 5-year old girl, who initially presented with acute epiglottitis, sepsis and multi-organ failure. She was subsequently diagnosed as having Systemic Lupus Erythematosus. To the best of our knowledge, this article describes the first case of Haemophilus influenzae type f epiglottitis as the initial presentation of SLE in childhood

Implementation and assessment of a structured curriculum for a 4-week pediatric rheumatology rotation for pediatric residents

Abstract Background General pediatricians often initially address children’s musculoskeletal (MSK) issues and play a crucial role in triaging and managing patients’ rheumatologic conditions. This study assessed the effectiveness of a structured curriculum in enhancing pediatric residents’ knowledge, MSK examination skills, and confidence during a 4-week pediatric rheumatology rotation. Methods Pediatric residents in their either second or third year who participated in the 4-week rheumatology rotation once across three academic years (July 2020–June 2023) were enrolled. Residents’ knowledge, MSK examination skills, and confidence were assessed at pre- and post-rotation by using 25 multiple-choice questions, the Thai pediatric Gait Arms Legs Spine examination, and a questionnaire, respectively. The curriculum comprised instruction on MSK examinations, interactive lectures, case-based discussion, topic reviews, MSK radiology conference, clinical experience in rheumatology clinic and consultations, with self-guided learning with educational resources. Results Fifty-eight pediatric residents (48 females, 10 males) with a mean age of 28.9 ± 0.8 years participated. Significant improvements were noted postrotation. Knowledge scores rose from 63.0 ± 12.2 to 79.7 ± 9.1 (mean difference 16.7 ± 10.3, p < 0.001). Similarly, MSK examination scores increased from 67.5 ± 14.4 to 93.6 ± 8.7 (mean difference 26.1 ± 14.6, p < 0.001). Residents also reported a marked increase in confidence across all evaluated areas, including history taking, MSK examination, arthrocentesis, and diagnosing and treating rheumatologic conditions (p < 0.001). Conclusions The 4-week structured curriculum in the pediatric rheumatology rotation significantly enhanced pediatric residents’ knowledge, MSK examination skills, and confidence. These findings support the integration of pediatric rheumatology rotations into pediatric residency training programs

Neonatal Multisystem Inflammatory Syndrome (MIS-N): The First Case Report in Thailand

Cases of multisystem inflammatory syndrome in children (MIS-C-like disease), have rarely been reported in neonates. A 33-week gestational age twin B female neonate presented with respiratory distress, tachycardia, and abdominal distention at 15 days of age. Echocardiogram found reduced left ventricular ejection fraction to 33%. Cardiac enzyme levels were all elevated: creatine kinase-MB 6.1 ng/mL (normal 0&ndash;4.5 ng/mL), troponin-T 170 ng/L (normal &lt; 14 ng/L) and NT-proBNP &gt; 35,000 pg/mL (normal 250.0 to 3987.0 pg/mL). Multiplex PCR of nasopharyngeal swab material was negative for respiratory pathogens. Serological tests revealed negative anti-spike SARS-CoV-2 IgM but positive anti-nucleocapsid SARS-CoV-2 IgG in both the mother and the patient. The mother provided a history of COVID-19 during pregnancy at 19 weeks gestation. The patient was diagnosed with neonatal multisystem inflammatory syndrome (MIS-N) and successfully treated with intravenous immunoglobulin (two doses of 1 gm/kg/dose) and methylprednisolone (2 mg/kg/day for 5 days then tapered off). She later developed coronary vessel (LMCA and RCA) dilation. The non-identical twin A did not develop MIS-N, suggesting a role of host genetic background. Newborn infants born to SARS-CoV-2-infected mothers at any time during pregnancy should be closely monitored for MIS-N. The optimal treatment approaches to this syndrome and the prognosis require further study

Cost–utility and budget impact analysis of tocilizumab for the treatment of refractory systemic juvenile idiopathic arthritis in Thailand

Objectives This study aimed to analyse the cost–utility and budget impact of adding tocilizumab to the standard treatment for patients with refractory systemic juvenile idiopathic arthritis (sJIA) in Thailand.Design Economic evaluation using a decision-analytical model.Setting Thailand.Participants Patients with refractory sJIA who were ≥2 years old.Methods The use of tocilizumab as an add-on therapy to standard treatment was compared with standard treatment alone. A simulated health state transition model was used to estimate the lifetime costs and health outcomes from a societal perspective. Direct medical costs were collected from tertiary hospital databases while direct non-medical costs were derived from interviews. Health-related quality of life (QoL) was measured using the proxy version of three-level EuroQol five-dimensional questionnaire (EQ-5D-3L). Future costs and outcomes were discounted at an annual rate of 3%. The base case population was patients aged 9.41 years old at refractory disease onset. The results were reported as incremental cost-effectiveness ratios (ICER) in US dollar (USD). One-way and probabilistic sensitivity analysis were conducted to investigate parameter uncertainty. The 5-year budget impact was estimated from a governmental perspective.Results The ICER of standard treatment plus tocilizumab was US$35 799 per quality-adjusted life-year (QALY) gained compared with standard treatment alone, which was not cost-effective at the threshold of US$5128 per QALY gained. The estimated 5 years budget impact was approximately US$4.8 million.Conclusions The use of standard treatment plus tocilizumab was not cost-effective in the Thai context, which has limited data. However, there is currently no second-line treatment for refractory sJIA in the Thai National List of Essential Medicines; thus, patients must receive higher doses of standard treatment which can cause many side effects. In contrast, tocilizumab showed obvious efficacy in clinical trials in improving treatment response and QoL. Therefore, the price of tocilizumab should be negotiated to reduce the financial impact on the healthcare system
