Background:
With the widespread use of hemocoagulase in patients with gastrointestinal bleeding, clinicians have become increasingly concerned about coagulation disorders associated with this medication. Risk factors for hypofibrinogenemia associated with hemocoagulase are poorly understood.
Aim:
To determine risk factors for hemocoagulase-associated hypofibrinogenemia in patients with gastrointestinal bleeding.
Methods:
We performed a retrospective analysis of the medical documentation of hospitalized patients treated with hemocoagulase for gastrointestinal bleeding. Hypofibrinogenemia was defined as a decrease in plasma fibrinogen concentration to less than 2.0 g/L. The included patients were divided into two groups: acquired hypofibrinogenemia group and non-hypofibrinogenemia group. We used logistic regression analysis to identify potential risk factors and established risk assessment criteria by employing a receiver operating characteristic curve.
Results:
There were 36 patients in the acquired hypofibrinogenemia group and 73 patients in the non-hypofibrinogenemia group. The hypofibrinogenemia group showed higher rates of intensive care unit admissions (P = 0.021), more female patients (P = 0.005), higher in-hospital mortality (P = 0.027), larger hemocoagulase doses (P = 0.026), more Packed Red Cells transfusions (P = 0.024), and lower baseline fibrinogen levels (P < 0.000). Binary logistic regression was employed to examine the risk factors associated with acquired hypofibrinogenemia. The analysis revealed that baseline fibrinogen [odds ratio (OR) 0.252, 95%CI: 0.137-0.464, P < 0.000], total hemocoagulase doses (OR 1.074, 95%CI: 1.015-1.137, P = 0.014), and female gender (OR 2.856, 95%CI: 1.015-8.037, P = 0.047) were statistically significant risk factors.
Conclusion:
Higher doses of total hemocoagulase, female gender, and a lower baseline fibrinogen level were risk factors for hemocoagulase-associated hypofibrinogenemia in patients with gastrointestinal bleeding.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
