Diagnosis and Management of Factor XIII Deficiency in Childhood: A 12-Year Retrospective Study (ASPHO 2026) - "Prophylactic therapy with recombinant FXIII-A2 (NovoThirteen) significantly increased mean FXIII activity from 1.54 ± 1.12% to 13.57 ± 2.72% (p < 0.001)... Congenital FXIIID should be suspected in neonates with unexplained umbilical bleeding, particularly in populations with high consanguinity. Early diagnosis, family screening, and regular prophylaxis with recombinant FXIII concentrate effectively prevent severe bleeding and improve outcomes. Greater clinician awareness is essential to reduce diagnostic delays and related morbidity."

A multicenter, real-world experience with recombinant FXIII for the treatment of patients with FXIII deficiency: from pharmacokinetics to clinical practice. The Italian FXIII Study. (PubMed, Blood Transfus) - "Efficacy and safety of rFXIII were proven in all patients. The dosage and infusion timing for the treated patients sometimes differed to those reported in the MENTOR pivotal studies, thus underlying the importance of tailored management in a real-world scenario."

The pharmacokinetics of recombinant FXIII (catridecacog) from the MENTOR2 trial to a real-world study: a head-to-head comparison. (PubMed, J Thromb Thrombolysis) - "In the RW 55.6% of patients were females, 26.2% in the MENTOR2 (p < 0.05). The mean dosage of drug used for the PK assessment was 35 IU/kg in the MENTOR2, and 33.9 IU/kg in the RW study."

Catridecacog in the treatment of an Italian population of patients with FXIII deficiency from pharmacokinetics to clinical outcomes (the Italian rFXIII study) (BIC 2021) - "Efficacy and safety of prophylaxis with catridecacog was proven in all patients, also in preventing severe bleeding. The cumulative PK profile was similar to that reported in the MENTOR studies, but dosage and infusion timing for each patient were in some cases very different."

[VIRTUAL] A Novel Assay Using Enzyme Capture – ELISA for Accurate Determination of Factor XIII Activity (ASH 2020) - "Methods : A standard curve was established by diluting known concentrations of recombinant factor XIII-A (rFXIII-A; Tretten) into (1) fXIII-A congenitally deficient and (2) fXIII immunodepleted plasma to determine if our assay is able to detect variable fXIII concentrations from 1 to 200% (0.01 - 2 IU/mL)... We conclude that Enzyme Capture-ELISA is a promising novel method for accurate detection of FXIII activity and is expected to improve sensitivity at low levels (<20%; <0.02 IU/mL), which are most clinically relevant. Further experiments are needed to refine the upper limit of assay linearity and thereby refine the dynamic range of the assay. With further optimization and validation, the EC-ELISA method may provide an improved diagnostic assay."
