[Changes on platelet adhesion, aggregation and production in course of mumps and mumps meningitis (author's transl)]
Insights
Mumps infection in children temporarily impacts platelet production and function. Platelet adhesion and aggregation increase during illness, correlating with antibody development.
Area of Science:
- Hematology
- Virology
- Immunology
Context:
- Mumps, a viral illness, can lead to complications like mumps meningitis.
- Thrombocyte (platelet) function and production are crucial for hemostasis.
Purpose:
- To investigate thrombocyte function, thrombopoiesis, and platelet count in children with mumps and mumps meningitis.
- To explore the relationship between platelet parameters and the immune response during mumps infection.
Summary:
- In 20 children with mumps, platelet adhesion and aggregation significantly increased from day 5 to 15.
- A decrease in megathrombocytes was observed in the first four days, followed by increased thrombopoiesis and platelet counts from day 5.
- Enhanced thrombopoiesis subsided by the third week, while platelet adhesion and aggregation remained elevated, correlating with specific antibody development.
Impact:
- This study highlights the dynamic changes in platelet function and production during mumps infection.
- Findings suggest a link between the immune response to mumps virus and altered platelet activity.
- Understanding these mechanisms may inform clinical management of mumps-related complications.
Abstract:
In 20 children with mumps and mumps meningitis thrombocyte functions, the thrombopoiesis and the platelet count were examinated over a four week period. The spontaneous, standardized platelet adhesion and aggregation on silikonized glass surface showed a statistically significant increase from the 5th to the 15th day of the illness. Within the first four days a decrease of the megathrombocyte portion respectively of the youngest platelet forms was noted as revealed by the platelet spreading preparations. Then the thrombopoiesis index as well as the platelet count arised from the 5th day of the illness parallel to the other platelet functions. The enhanced thrombopoiesis diminished at the end of the 3rd week of the illness but the platelet adhesion and aggregation continued to be further increased. A distinct correlation could be established between the development of the specific antibodies and increased platelet adhesion, aggregation and thrombopoiesis in epidemic parotitis. The influence of the immune complexes and of the virus itself, furthermore the occurrence of the regenerating phase as well as the effects of the possible thromboplastic activity following a tissue damage or an inflammatory reaction were discussed.
