Prognostic value of combined platelet and fibrinogen levels on mortality in pediatric patients with sepsis.

BACKGROUND: Sepsis causes high mortality in pediatric intensive care units (PICUs), often involving coagulation dysfunction. While platelets and fibrinogen are crucial, their combined prognostic value in pediatric sepsis remains unclear. We investigated their additive utility on in-PICU mortality. METHODS: This retrospective cohort study included 282 pediatric sepsis patients admitted to the Zhujiang Hospital PICU (June 2022-December 2024). Multivariable Cox regression evaluated biomarkers continuously and categorically based on admission levels: platelets (cutoff: 150×109/L) and fibrinogen (…

Defining a fibrinogen-to-factor XIII replacement ratio in an in-vitro model of dilutional coagulopathy.

BACKGROUND: Massive blood loss during surgery or trauma leads to dilutional coagulopathy. While fibrinogen is typically the first factor to reach critical levels, factor XIII (FXIII) also decreases proportionally, further impairing clot stability. Routine coagulation tests are insensitive to FXIII, leading to unrecognised deficiency during acute bleeding. This study aimed to define an optimal fibrinogen-to-FXIII replacement ratio to empirically restore adequate haemostasis. METHODS: In an in-vitro haemodilution model using blood from 20 healthy volunteers, we simulated a 70% loss of circulati…

The Fibrinogen-to-Albumin Ratio in Endometriosis: A Step Toward Personalized Non-Invasive Diagnostics.

Background/Objectives: Endometriosis is a chronic inflammatory disease affecting up to 10-15% of women of reproductive age and is frequently associated with pelvic pain and infertility. Non-invasive biomarkers remain insufficient for accurate diagnosis, often necessitating laparoscopic confirmation. The fibrinogen-to-albumin ratio (FAR), a composite marker of systemic inflammation, has been proposed in both oncological and cardiovascular disease but has not yet been evaluated in endometriosis. Methods: We conducted a retrospective monocentric study including 390 women who underwent laparoscopy…

The Association of Serum Fibrinogen Levels With the Severity of Primary Postpartum Hemorrhage: A Prospective Study.

INTRODUCTION: Postpartum hemorrhage (PPH) remains a major cause of maternal mortality and morbidity worldwide. Coagulation disorders are a major risk factor for PPH that have not been studied adequately. Fibrinogen, a plasma glycoprotein, is integral to hemostasis and is involved in the final process of the coagulation cascade. Fibrinogen levels increase with advancing pregnancy probably because of an increase in estrogen levels and reach a peak (~5g/L) in the third trimester of pregnancy. However, in the postpartum period, the fibrinogen concentration shows a decreasing trend. OBJECTIVE: The…

Abnormal fibrinogen with an Aα 16Arg → Cys substitution is associated with multiple cerebral infarctions.

We found a heterozygous dysfibrinogenemia caused by a substitution of AαArg16Cys. The proband suffered multiple cerebral infarctions. Routine coagulation tests revealed a prolonged thrombin time. The fibrinogen levels in the functional assays were considerably lower than the levels in the immunological assays. The polymerization of the purified fibrinogen was strongly impaired in the presence of calcium. As previously observed in other heterozygous Aα R16C variants, the release rate and amount of fibrinopeptide A (FPA) were lower in the proband than those in normal controls. Additionally, the …

Comparing efficacy and safety of fibrinogen concentrate to cryoprecipitate in bleeding patients: a systematic review.

BACKGROUND: Bleeding is associated with the depletion of fibrinogen, thus increasing the risk of coagulopathy, further bleeding and transfusion requirements. Both fibrinogen concentrate and cryoprecipitate replenish low plasma fibrinogen levels. This systematic review aims to identify and evaluate evidence of efficacy and safety of fibrinogen concentrate and cryoprecipitate in bleeding patients. METHOD: Cochrane Central Register of Controlled Trials (CENTRAL), Medline, EMBASE up to 2nd of March 2015 were among the electronic search strategies of randomized controlled trials and non-randomized…

Interaction of fibrinogen and muramidase-released protein promotes the development of Streptococcus suis meningitis.

Muramidase-released protein (MRP) is as an important virulence marker of Streptococcus suis (S. suis) serotype 2. Our previous works have shown that MRP can bind human fibrinogen (hFg); however, the function of this interaction in S. suis meningitis is not known. In this study, we found that the deletion of mrp significantly impairs the hFg-mediated adherence and traversal ability of S. suis across human cerebral microvascular endothelial cells (hCMEC/D3). Measurement of the permeability to Lucifer yellow in vitro and Evans blue extravasation in vivo show that the MRP-hFg interaction significa…

The role of fibrinogen and haemostatic assessment in postpartum haemorrhage: preparations for a randomised controlled trial.

Pregnancy is a state of hypercoagulobility that might be an evolutionary way of protecting parturients from exsanguination following child birth. Observational studies suggest an association between a low level of fibrinogen (coagulation factor I) at the start of postpartum haemorrhage (PPH) and subsequent severity of bleeding. Fibrinogen concentrate may be prescribed to correct acquired hypofibrinogenaemia, but evidence is lacking regarding the treatment efficacy. This thesis assesses the current evidence for the use of fibrinogen concentrate and haemostatic assessment in bleeding patients wi…

Introduction of an algorithm for ROTEM-guided fibrinogen concentrate administration in major obstetric haemorrhage.

We compared blood component requirements during major obstetric haemorrhage, following the introduction of fibrinogen concentrate. A prospective study of transfusion requirements and patient outcomes was performed for 12 months to evaluate the major obstetric haemorrhage pathway using shock packs (Shock Pack phase). The study was repeated after the pathway was amended to include fibrinogen concentrate (Fibrinogen phase). The median (IQR [range]) number of blood components given was 8.0 (3.0-14.5 [0-32]) during the Shock Pack phase, and 3.0 (2.0-5.0 [0-26]) during the Fibrinogen phase (p = 0.00…
