Abstract

Objectives: To investigate the application value of thromboelastography (TEG) in assessing coagulation function in children with severe hemophilia A (HA) after emicizumab (EMI) therapy.

Methods: A retrospective analysis was performed on the activated partial thromboplastin time (APTT) and TEG testing results of 17 children with severe HA before and after EMI treatment at Shenzhen Children's Hospital from January 2023 to July 2024. Correlation analysis was conducted between coagulation factor VIII (FVIII) equivalent activity and reaction time (R value) measured by TEG.

Results: After EMI treatment, the mean bleeding rate for children with severe HA was 1.6 events per year, with 15 children (88%) without spontaneous bleeding or joint bleeding. The children with severe HA showed a significant reduction in APTT after EMI treatment (P<0.05), with a significantly shorter APTT than the normal control group (P<0.05). There was no correlation between APTT and FVIII equivalent activity after treatment (P>0.05). After EMI treatment, TEG parameters, including R value, kinetic time, alpha angle (α), maximum amplitude, clot strength, and coagulation index, shifted from a hypocoagulable state before treatment to a nearly normal state after treatment (P<0.05). The R value demonstrated a strong negative correlation with FVIII equivalent activity (r=-0.758, P<0.05).

Conclusions: The bleeding condition of children with severe HA can be effectively controlled after EMI treatment. Routine APTT testing cannot reflect true coagulation function, whereas TEG testing is clinically valuable in assessing the coagulation function of children with severe HA undergoing EMI treatment.

期刊介绍： The Chinese Journal of Contemporary Pediatrics (CJCP) is a peer-reviewed open access periodical in the field of pediatrics that is sponsored by the Central South University/Xiangya Hospital of Central South University and under the auspices of the Ministry of Education of China. It is cited as a source in the scientific and technological papers of Chinese journals, the Chinese Science Citation Database (CSCD), and is one of the core Chinese periodicals in the Peking University Library. CJCP has been indexed by MEDLINE/PubMed/PMC of the American National Library, American Chemical Abstracts (CA), Holland Medical Abstracts (EM), Western Pacific Region Index Medicus (WPRIM), Scopus and EBSCO. It is a monthly periodical published on the 15th of every month, and is distributed both at home and overseas. The Chinese series publication number is CN 43-1301/R；ISSN 1008-8830. The tenet of CJCP is to “reflect the latest advances and be open to the world”. The periodical reports the most recent advances in the contemporary pediatric field. The majority of the readership is pediatric doctors and researchers.
