Clinical features and laboratory findings of multisystem inflammatory syndrome in children (MIS-C)

Introduction: Children mostly have mild or asymptomatic forms of SARS-CoV-2 infection, but during pandemic a higher incidence of Kawasaki disease, Kawasaki-like syndrome and the emergence of a new clinical entity, multisystem inflammatory post-covid syndrome (MIS-C) has also been observed. Objectives: The aim of this study is to determine clinical features and laboratory findings in patients with MIS-C. Methods: Retrospective analysis of clinical features and laboratory findings of MIS-C patients treated at our tertiary referal center (Clinic of Pediatric, University Clinical Centre Nis, Serbia). Results: From 18th of March 2020 till 30st of April 2021 there were 10 patients diagnosed as MIS-C according to CDC criteria. Eight patients were male and two were female. Patients age was 2 to 13 years (average 7.9 years, median 7 years). All patients had SARS -CoV-2 N-protein IgG antibodies but without history of disease symptoms and had positive contact four weeks prior to the onset of MIS-C symptoms. First symptom of MIS-C was fever (over 38C) which lasted in average for 4.4 days (3-7 days). Muco-cutaneous and gastrointestinal manifestations were most common. All patients had bulbar conjuctivitis, rash was present in 8 patients (80%), hand/foot oedema in 6 cases (60%), anterior cervical lymphadenopathy and cheliitis in 4 cases (40%) and periobital oedema in one case (details presented in Table 1. Clinical features of MIS-C patients). Nine patients (90%) presented with gastrointestinal symptoms while nervous system was affected in 5 patients. Three patients developed heart insuffitiency and one patient developed early signs of right coronary arthery aneurism. All patients had elevated inflammatory markers. Complete blood count showed elevated levels of white blood cells in 9 patients. Hypoalbuminemia and hypoproteinemia, low levels of serum potassium and sodium were present during ten days after the onset of symptoms. Troponines were elevated in 4 cases, proBNP in 5 cases. Abdominal ultrasound was performed and 6 patients presented with hepatoplenomegaly, 3 with enlarged spleen, one with enlagred liver and 4 had ascites. All patients were treated with combination of two antibiotics till cultures were proven negative, corticosteroid therapy and antiaggregation therapy. Three patients received a IVIG in a single dose (2gr/kg). All patients had good response to corticosteroid therapy (2mg/kg). Corticosteroid therapy was continued for four weeks (tapering). Conclusion: MIS-C can be a life-threatening condition in children. Early diagnosis and timely adequate treatment are of paramount importance. In children less than 5 years of age, the distinction between Kawasaki (Kawasaki shock) syndrome and MIS-C might be difficult, influencing the decision to use IVIG or steroids alone.

Attitudes of primary and secondary students towards online lessons during Covid-19

The spread of the coronavirus (COVID-19) forced the closure of schools nationwide at the outset of the pandemic. The aim of this paper is to examine the attitudes of primary/secondary school students in Novi Sad, Serbia towards online lessons during pandemic. However, the online course on geography was open to non-Serbian students i.e. students from other countries who used Preply platform. The research was conducted based on the online survey regarding the attitudes of students. Main results of data analysis indicate that students prefer face to face lessons. Around 15.8% of students recommend using only online lessons in the future. Live lesson e.g. Google Meet, Zoom was mostly given to respondents. © 2021 ACM.
