Fibrinogen is a complex protein playing a major role in coagulation. Congenital afibrinogenemia, characterized by the complete absence of fibrinogen, is associated with major hemostatic defects. Even though the clinical course is unpredictable and can be completely different among patients, severe bleeding is the prominent symptom. Patients are also at increased risk of thrombosis and sometimes suffer from spontaneous spleen rupture, bone cysts and defective wound healing. Due to the relative rarity of afibrinogenemia, there are no evidence-based strategies for helping physicians in care of these patients. Fibrinogen supplementation is the keystone to prevent or treat bleeding events. In addition, fibrinogen, a pleiotropic protein with numerous physiological roles in immunity, angiogenesis and tissue repair, is involved in many diseases. Indeed, depletion of fibrinogen in animal models of infections, tumors and neurological diseases has an effect on the clinical course. The consequences for patients with afibrinogenemia still need to be investigated.

Objective To investigate the classification, clinical manifestations, laboratory findings, and genetic mutations associated with hereditary fibrinogen disorders in Chinese population. Methods Between February 2015 and February 2022, 65 patients with congenital fibrinogen disorders (CFD) were identified at Wuhan Union Hospital. Comprehensive data were available for 51 patients, allowing for a retrospective analysis.

Objective: The occurrence of hypofibrinogenemia after tocilizumab treatment has attracted increasing attention, which may cause bleeding and even life-threatening. This study aims to explore the risk factors for tocilizumab-induced hypofibrinogenemia (T-HFIB) and construct a risk prediction model.
Methods: A total of 221 inpatients that received tocilizumab from 2015 to 2023 were retrospectively collected and divided into T-HFIB group or control group.

Quantitative fibrinogen disorders, including afibrinogenemia and hypofibrinogenemia, are defined by the complete absence or reduction of fibrinogen, respectively. The diagnosis is based on the measurement of fibrinogen activity and antigen levels, which define the severity of this monogenic disorder. Afibrinogenemia is the result of homozygosity or combined heterozygosity for the causative mutations, whereas monoallelic mutations lead to hypofibrinogenemia.

Background: Congenital hypofibrinogenemia, a quantitative fibrinogen disorder, is characterized by abnormally low levels of both functional and antigen fibrinogen. We identified a heterozygous nonsense mutation, p.Arg17Stop, in the fibrinogen Bβ chain of a three-month-old female infant.

Congenital dysfibrinogenemia (CDF) is the most common type of congenital fibrinogen disorders, characterized by dysfunctional fibrinogen. Its prevalence is significantly underestimated due to the absence of obvious clinical symptoms in most patients. In addition to bleeding manifestations, patients with CDF may experience thrombotic events or pregnancy-related complications.
