abstract = {Parvovirus B19 is a known cause of erythema infectiosum,
aplastic crises and severe anemia, especially in patients
with hemolytic anemia. The aim of this study was to
investigate the clinical and diagnostic parameters of
parvovirus B19 infection in children with and without
hemolytic anemia and to record the course of case numbers in
recent years.We retrospectively included all patients
diagnosed with acute parvovirus B19 infection at the
Department of Pediatrics, Jena University Hospital, Jena,
Germany between 2016 and 2024. Diagnosis was confirmed by
positive parvovirus B19 IgM serology and/or PCR testing.
Both demographic and clinical data as well as diagnostic
parameters were collected and analyzed, focusing on
differences between children with and without underlying
hemolytic anemia.Among the 40 pediatric patients included in
this study, 14 patients were diagnosed with hemolytic
anemia. Children with hemolytic anemia suffered from a
significantly greater hemoglobin drop and a significantly
higher need for transfusion compared to children without
hemolytic anemia. A Poisson regression model, adjusted for
observation time, was used to compare case rates between
2016 and 2022 and 2023-2024.The model demonstrated a more
than fivefold increase in parvovirus B19 cases in 2023-2024
compared to 2016-2022.Children with hemolytic anemia, such
as spherocytosis, are at higher risk of severe anemia and
require more frequently transfusions during acute parvovirus
B19 infection. The observed increase in cases after 2022
suggests changing epidemiological patterns and highlights
the need for careful surveillance and early diagnostic and
therapeutic interventions in affected children.},
