Abstract

Aim: Risk factors that cause severe clinical outcomes caused by COVID-19 are better defined in adult patients than in the pediatric patient group. In this study, it was aimed to evaluate the relationship between socio-demographic characteristics, clinical findings and cycle threshold (Ct) value in pediatric patients who applied to our hospital with the suspicion of COVID-19 and were found to have a positive SARS-CoV-2 test. Method: In the study, 2971 pediatric patients with positive SARS-CoV-2 RT-qPCR test in Mersin University Hospital COVID-19 laboratory between 1 May 2020 and 31 October 2021 were included in the study. The SARS-CoV-2 RT-qPCR test was performed on nasopharyngeal and oropharyngeal swab samples. Ct values obtained from the RT-qPCR result were classified as low, moderate, and high. Results: The most common symptoms in pediatric patients with positive SARS-CoV-2 infection were fever 41.5%, cough 28.6% and sore throat 24.4%, respectively. Ct values of SARS-CoV-2 positive asymptomatic and symptomatic pediatric patients are low (<24) and the patients are in the high risk group. When the relationship between symptoms and Ct groups in SARS-CoV-2 positive children was evaluated, it was determined that patients with fever (43.1%), fatigue (18.8%) and headache (16.3%) were in the high viral load group. Conclusion: Most of the contact patients in our study were thought to have low Ct value because they were exposed to a family member with COVID-19. Therefore, monitoring, control and isolation of this contact group with high potential contagion is an important point in terms of public health.

Özet

Amaç: COVID-19’un yol açtığı şiddetli klinik sonuçlara neden olan risk faktörleri yetişkin hastalarda çocuk hasta grubuna göre daha iyi tanımlanmıştır. Bu çalışmada hastanemize COVID-19 şüphesi ile başvuran ve SARS-CoV-2 testi pozitif saptanan çocuk hastalarda sosyo-demogrofik özellikler, klinik bulgular ve eşik değeri “cycle threshold” (Ct) değeri arasındaki ilişkinin değerlendirilmesi amaçlanmıştır. Yöntem: Çalışmada 1 Mayıs 2020-31 Ekim 2021 tarihleri arasında Mersin Üniversitesi Hastanesi COVID-19 laboratuvarında SARS-CoV-2 RT-qPCR testi pozitif saptanan 2971 çocuk hasta çalışmaya dahil edilmiştir. SARS-CoV-2 RT-qPCR testi, nazofarengeal ve orofarengeal sürüntü örneklerinden yapılmıştır. RT-qPCR sonucundan elde edilen Ct değerleri düşük, orta, yüksek şeklinde sınıflandırılmıştır. Bulgular: SARS-CoV-2 enfeksiyonu pozitif olan çocuk hastalarda en sık görülen semptomlar sırasıyla ateş %41.5, öksürük %28.6 ve boğaz ağrısı %24.4 olarak belirlenmiştir. SARS-CoV-2 pozitif asemptomatik ve semptomatik çocuk hastaların Ct değerleri düşüktür (<24) ve hastalar yüksek risk grubunda yer almaktadır. SARS-CoV-2 pozitif çocuklarda semptomlar ve Ct grupları arasındaki ilişki değerlendirildiğinde özellikle ateş (%43.1), halsizlik (%18.8) ve baş ağrısı (%16.3) semptomu gösteren hastaların yüksek viral yük grubunda olduğu saptanmıştır. Sonuç: Çalışmamızda yer alan temaslı hastaların çoğunun COVID-19’lu aile üyelerinden birine maruz kalması nedeniyle Ct değerinin düşük olduğu düşünülmektedir. Bundan dolayı potansiyel bulaştırıcılıkları yüksek olan bu temaslı grubunun takibi, kontrolü ve izolasyonu halk sağlığı açısından önemli bir noktadır.
