[The behaviour of platelets in some viral infectious diseases in childhood (author's transl)]
Insights
Viral infections in children can cause subclinical thrombocytopenia, a decrease in platelet count not visible externally. This study found low platelet counts in over half of children with measles and infectious mononucleosis, with spontaneous recovery.
Area of Science:
- Pediatric infectious diseases
- Hematology
- Virology
Context:
- Viral infections are common in children.
- Platelets play a crucial role in hemostasis.
- Subclinical changes in platelet count during viral infections are not well-understood.
Purpose:
- To investigate the prevalence of subclinical thrombocytopenia in children with common viral infections.
- To document platelet counts during the course of illness in pediatric patients.
Summary:
- A study of 207 children (7 months to 12 years) revealed subclinical thrombocytopenia in 55% with measles, 25% with mumps, 45% with varicella, 30% with German measles, and 55% with infectious mononucleosis.
- No hemorrhagic manifestations were observed in any cases.
- Platelet counts normalized spontaneously in all affected children.
Impact:
- Highlights the frequent occurrence of asymptomatic low platelet counts during childhood viral illnesses.
- Suggests that viral infections can transiently impact platelet production or increase consumption without clinical bleeding.
- Provides data for understanding the hematological response to viral pathogens in pediatric populations.
Abstract:
To evidentiate a participation clinically not evident of thrombocytes during viral infections, the Authors performed platelets count in 207 children of age varying 7 months to 12 years from the diagnosis and during the course of the illness. A subclinical thrombocytopenia was revealed in 55% of children affected by measles, in 25% of mumps, in 45% of varicella, in 30% of german measles and in 55% of infectious mononucleosis. In all the cases we didn't observe hemorrhagic manifestations and platelets count has come back to normal and higher levels spontaneously. Previously the Authors discuss pathogenetic ways which may have a role in subclinically thrombocytopenia during viral infectious diseases.
