Insights
The THROMKIDplus study establishes a patient registry and biomaterial bank for inherited platelet disorders (IPDs) in children across Germany, Austria, and Switzerland. This initiative aims to improve diagnosis, treatment, and research for these rare conditions.
Area of Science:
- Pediatric Hematology
- Genetics
- Clinical Research
Background:
- Inherited platelet disorders (IPDs) encompass a range of quantitative and qualitative defects affecting platelet function.
- Understanding IPDs is crucial for improving patient diagnosis, treatment, and advancing translational research.
- A need exists for comprehensive data and biomaterial collection in pediatric IPD patients.
Purpose of the Study:
- To establish a multicenter patient registry and biomaterial bank for children with inherited platelet disorders.
- To facilitate translational research by collecting blood samples (smears, plasma, pellets, DNA) for future genetic and molecular studies.
- To enhance knowledge regarding the prevalence, pathogenesis, and clinical outcomes of IPDs in pediatric populations.
Main Methods:
- A retrospective-prospective, multicenter observational study design.
- Enrollment of patients aged 0-17 years diagnosed with or suspected of having IPDs.
- Data collection via the MARVIN platform, adhering to good clinical practice and data protection regulations.
Main Results:
- The THROMKIDplus registry is set to launch in late 2023, involving 24 centers in Germany, Austria, and Switzerland.
- The study aims to retrospectively enroll approximately 200 patients and prospectively enroll about 50 patients annually.
- Collected data includes patient history, laboratory results, bleeding tendencies, and congenital defects, alongside stored biomaterials.
Conclusions:
- The THROMKIDplus initiative represents a significant step towards a centralized resource for pediatric IPD research.
- This registry and biobanking effort will support in-depth genetic, molecular, and physiological investigations.
- The project is expected to significantly improve the understanding and management of inherited platelet disorders in children.
Abstract:
Inherited platelet disorders (IPDs) represent a heterogeneous group of disorders that include both quantitative (thrombocytopenia or thrombocytosis) and qualitative (thrombocytopathy) defects. To gain better knowledge about the prevalence, pathogenesis, and clinical consequences of specific diseases, to improve diagnosis and treatment of patients with IPD, and to support translational research on a genetic, molecular, and physiological basis, the THROMKIDplus study group currently comprising 24 sites in Germany, Austria, and Switzerland decided to establish a patient registry with associated biomaterial banking for children. This registry is designed as a retrospective-prospective, multicenter observational study and supposed to launch in the second half of 2023. Blood smears, plasma, platelet pellets, and DNA of patients will be stored in certified biomaterial banks for future translational research projects. The main inclusion criteria are (1) diagnosis of or highly suspected IPD after assessment of a THROMKIDplus competence center and (2) patients aged 0 to 17 years. Initial and follow-up data on patient history, laboratory parameters, standardized documentation of bleeding tendency, and congenital defects are collected according to good clinical practice and current data protection acts by using the MARVIN platform, a broadly used data management system supported by the German Society for Pediatric Oncology Hematology (GPOH). The THROMKIDplus study group intends to enroll ∼200 patients retrospectively and an annual amount of ∼50 patients prospectively.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
