Bleeding in the neonates may be a result of thrombocytopenia, sepsis or vitamin K deficiency. Congenital bleeding disorders are a rare cause of bleeding. The umbilical cord bleed is an important clue to underlying bleeding disorders especially factor XIII deficiency and afibrinogenemia. In some laboratories, the routine workup for the bleeding neonate may not always include fibrinogen assays, which may then delay this diagnosis. We report a case of congenital afibrinogenemia in a neonate who presented with umbilical stump bleeding for its rarity and to re-emphasize the need for including fibrinogen assays while assessing a bleeding neonate.

Background: Spontaneous splenic rupture is a rare life-threatening finding with a challenging diagnosis which is largely ignored in the literature. Hematological disorders such as afibrinogenemia are reported to cause bleeding disorders mostly cerebral hemorrhage. Despite being a life-threatening condition, data about spontaneous splenic rupture in patients with Afibrinogenemia remain scarce.

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.
