A clinical overview of paediatric sarcoidosis: Multicentre experience from Turkey.

OBJECTIVES: We aimed to outline the demographic data, clinical spectrum, and treatment approach of sarcoidosis in a large group of patients and sought to figure out the variations of early-onset (EOS) and late-onset paediatric sarcoidosis (LOS). METHODS: The study followed a retrospective-descriptive design, with the analysis of medical records of cases diagnosed as paediatric sarcoidosis. RESULTS: Fifty-two patients were included in the study. The median age at disease onset and follow-up duration were 83 (28.2-119) and 24 (6-48) months, respectively. Ten (19.2%) cases had EOS (before 5th birthday) and 42 (80.7%) cases had LOS. The most common clinical findings at the time of the disease onset were ocular symptoms (40.4%) followed by joint manifestation (25%), dermatological symptoms (13.5%), and features related to multi-organ involvement (11.5%). Anterior uveitis was the most common (55%) one among ocular manifestations. Patients with EOS displayed joint, eye, and dermatological findings more commonly than patients with LOS. The recurrence rate of disease in patients with EOS (5.7%) and LOS (21.1%) were not statistically different (P = .7). CONCLUSIONS: Patients with EOS and LOS may present with variable clinical features and studies addressing paediatric sarcoidosis cases in collaboration between disciplines will enhance the awareness of this rare disease among physicians and assist early diagnosis with lesser complications.

Clinical features and outcomes of 76 patients with COVID-19-related multi-system inflammatory syndrome in children.

OBJECTIVES: Multi-system inflammatory syndrome in children (MIS-C) is a less understood and a rare complication of coronavirus disease-2019 (COVID-19). Given the scarce data regarding this novel disease, we aimed to describe the clinical features and outcomes of our patients with MIS-C and to evaluate the associated factors for the pediatric intensive care unit (PICU) admission. METHODS: The MIS-C patients under 18 years old diagnosed and treated in three referral centers between July 2020 and March 2021 were included. Data of the patients were retrospectively obtained from their medical records. RESULTS: Overall, 76 subjects (24 females) with a mean age of 8.17 ± 4.42 years were enrolled. Twenty-seven (35.5%) patients were admitted to the PICUs. The two most common systemic involvement patterns were cardiac and gastrointestinal. There was only one lethal outcome in a patient with underlying acute lymphoblastic leukemia. Those with higher procalcitonin levels at admission were found to stay longer in the hospital (r = 0.254, p = 0.027). The risk of PICU admission increased with age (aOR: 1.277; 95% CI: 1.089-1.498; p = 0.003) and with decreased initial serum albumin levels (aOR: 0.105; 95% CI: 0.029-0.378; p = 0.001). CONCLUSION: Although there is a wide clinical variability among the patients with MIS-C, we suggest that those with older age and lower initial serum albumin levels merit close monitoring due to their higher risk for PICU admission. Key Points • Although there is a wide variability regarding the management process among clinicians, MIS-C is a rare, severe, less understood complication of COVID-19 that may cause rapid clinical deterioration in the patients. • Clinicians should be aware of this condition in children with persistent fever and a family history of COVID-19. • Older age and low serum albumin levels are the independent predictors for the pediatric intensive care unit admission among MIS-C patients.
