Article Abstract

In order to reveal the possible physiological role of the kallikrein during the stress of birth, the prekallikrein and kallikrein inhibitor were evaluated in 15 pregnant women and in 15 newborns from terminated pregnancies. The results show a very low level of prekallikrein in the funiculus blood at the moment of birth and a still lower level in venous blood 24 hours after birth. No important changes resulted in the mother's blood either in pregnancy, nor at the end of the labour.

The plaques associated with Alzheimer's disease are formed as a result of the aggregation of Aβ peptides, which vary in length from 38 to 43 amino acids. The 1-40 peptide is the most abundant, while the 1-42 peptide appears to be the most destructive to neurons and/or glial cells in a variety of assays. We have demonstrated that aggregated Aβ, a state prior to plaque formation, will activate the plasma bradykinin-forming pathway when tested in vitro.

Lipopolysaccharide (LPS) is the primary pathogenic factor in Gram-negative sepsis. While the presence of LPS in the bloodstream during infection is associated with disseminated intravascular coagulation, the mechanistic link between LPS and blood coagulation activation remains ill-defined. The contact pathway of coagulation-a series of biochemical reactions that initiates blood clotting when plasma factors XII (FXII) and XI (FXI), prekallikrein (PK), and high molecular weight kininogen interact with anionic surfaces-has been shown to be activated in Gram-negative septic patients.

Hereditary angioedema with C1 inhibitor deficiency (HAE-C1-INH) is a rare disorder characterized by recurrent, potentially life-threatening swelling in various parts of the body, including the limbs, face, and airways Current treatments focus primarily on symptomatic relief and the management of acute attacks, without targeting the underlying genetic cause or the dysregulated bradykinin production. Donidalorsen, a novel antisense oligonucleotide, addresses a key driver of HAE-C1-INH by targeting prekallikrein (PKK) to reduce bradykinin levels. This meta-analysis evaluates the efficacy and safety of Donidalorsen versus placebo, focusing on two dosing regimens: 4-week and 8-week intervals.

The contact system in chronic kidney disease and hemodialysis - A cross-sectional study.

Thromb Res

January 2025

Department of Cancer and Inflammation Research, Institute for Molecular Medicine, University of Southern Denmark, Odense, Denmark; Department of Nephrology, Odense University Hospital, Odense, Denmark. Electronic address:

Background And Hypothesis: The contact system (CAS) is a part of both the immune system and the coagulation system. The involvement of the CAS in chronic kidney disease (CKD) and hemodialysis (HD) has been documented, yet conflicting findings have hindered a comprehensive understanding. This study aimed to investigate whether CAS activation occurs in patients with chronic kidney failure undergoing HD compared with those undergoing peritoneal dialysis (PD), patients with CKD not receiving replacement therapy, or healthy controls and to assess the impact of HD on CAS from pre- to post-dialysis during a single session of HD.

Background And Objectives: Patients with rare diseases like hereditary angioedema (HAE) are usually referred to an angioedema center to ensure guideline-compliant and experience-based therapy. Even though there are established guidelines and several approved therapeutics, there are still open questions and situations in the daily care of HAE patients, where an exchange between centers is needed.

Materials And Methods: A survey was conducted among physicians from German angioedema centers regarding challenges and issues in everyday HAE treatment.
