Insights
In pediatric Coronavirus Disease 2019 patients, leukopenia and thrombocytopenia indicate increased disease severity. Elevated D-dimer and prolonged prothrombin time were not associated with severe complications in this age group.
Area of Science:
- Hematology
- Infectious Diseases
- Pediatrics
Background:
- Hematologic and hemostatic abnormalities are linked to poor outcomes in adult COVID-19.
- The prognostic value of these markers in pediatric COVID-19 is not well-established.
Purpose of the Study:
- To investigate the prognostic significance of hematologic and hemostatic derangements in pediatric patients with acute Coronavirus Disease 2019.
Main Methods:
- Retrospective cohort study.
- Inclusion of patients younger than 22 years admitted for acute COVID-19.
- Analysis of hematologic (leukopenia, thrombocytopenia) and hemostatic (D-dimer, prothrombin time) markers.
Main Results:
- Leukopenia and thrombocytopenia were identified as independent predictors of disease severity.
- Most pediatric patients presented with elevated D-dimer or prolonged prothrombin time.
- These hemostatic markers did not correlate with severe clinical complications.
Conclusions:
- Leukopenia and thrombocytopenia are significant indicators of severity in pediatric COVID-19.
- Elevated D-dimer and prolonged prothrombin time may not predict severe outcomes in this population.
Abstract:
Leukopenia, thrombocytopenia, elevated D-dimer, and prolonged prothrombin time are considered poor prognostic factors in adults with acute Coronavirus Disease 2019. The prognostic significance of these abnormalities among pediatric patients remains underreported in the literature. This retrospective cohort study evaluates the prognostic implications of hematologic and hemostatic derangements in patients younger than 22-years-of-age who were admitted to a tertiary-care referral institution for management of acute Coronavirus Disease 2019 infection. Leukopenia and thrombocytopenia were identified as independent prognostic factors of disease severity. Although the majority of children, with available results, had elevated D-dimer or prolonged prothrombin time upon initial presentation, these markers were not found to be associated with the development of severe clinical complications.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
