Background: Thrombotic events in congenital factor (F)XIII deficiency are extremely rare. To our knowledge, we describe the first case of severe congenital FXIII deficiency associated with recurrent venous thrombotic events.
Key Clinician Question: How to deal with anticoagulation treatment in patients with severe FXIII deficiency?
Clinical Approach: The patient was treated with rivaroxaban and plasma-derived FXIII substitution therapy as prophylaxis without bleeding complications. We aimed at FXIII trough levels of 50% during the loading doses of rivaroxaban, then 30% during the maintenance dose of rivaroxaban, and finally 20% during the long-term use of prophylactic dose of rivaroxaban.
Conclusion: Treatment of thrombotic events with rivaroxaban in patients with severe bleeding disorders seems to be safe, requiring an adaptation of the intensity of the replacement therapy.

Blood clots are complex structures composed of blood cells and proteins held together by the structural framework provided by an insoluble fibrin network. Factor (F)XIII is a protransglutaminase essential for stabilizing the fibrin network. Activated FXIII(a) introduces novel covalent crosslinks within and between fibrin and other plasma and cellular proteins, and thereby promotes fibrin biochemical and mechanical integrity.

Individual differences in environmental sensitivity are linked to stress-related psychiatric symptoms. In previous research, we found that high environmental sensitivity can be a risk factor for increased inflammation and gut permeability, particularly when gut microbiome diversity is low. However, the specific gut bacterial taxa involved in this interaction remain unclear.

Thrombin is the central mediator of hemostasis, where it converts fibrinogen to fibrin, activates upstream factors to promote coagulation, activates factor XIII and thrombin-activatable fibrinolysis inhibitor to stabilize fibrin, mediates anticoagulation, and modulates cellular activity via cell surface receptors. Thus, regulation of thrombin activity is essential to the hemostatic balance. Thrombin is regulated by positively charged surface domains that surround the active site.

Acquired factor XIII (FXIII) deficiency is a rare disorder that could be associated with autoimmune and malignant disorders with a high risk of bleeding. In acute leukemias, acquired FXIII deficiency has been reported and replacement of FXIII helped to control significant bleeding. Here, we report four cases of myeloid neoplasms to have acquired FXIII deficiency with interesting concomitant RUNX1 mutation in the molecular background of two patients.

The transglutaminase (TGMs) family plays a crucial role in regulating mammalian reproduction, yet its impact on poultry reproductive traits has not been extensively studied. In this study, we identified eight members of the TGMs family in chickens and examined the contributions of genetic variations of coagulation factor XIII A chain (F13A1), transglutaminase 4 (TGM4), and LOC101749664 to selective breeding in commercial layers through genetic variation response pattern analysis. Transcriptome data from various tissues of high- and low-egg-yielding Gushi chickens revealed significant positive correlations between the mRNA expression levels of TGM4 and F13A1 genes and egg production (P < 0.
