To establish the incidence of the disseminated intravascular coagulation (DIC) syndrome, 76 patients who had died from acute myocardial infarction were clinically and anatomically analysed. The studies indicated that microcirculatory thrombosis in myocardial infarction occurred in the first to early second weeks of its development and localized in minor veins of one organ and only in 21.4% of cases it involved three organs or more. The DIC-syndrome was morphologically evidenced only in 19.1% of the patients having a history of cardiogenic shock. Microcirculatory thrombosis more frequently occurred in females. Old age, persistent hypertension, diabetes mellitus were found to predispose to its development.

Infection type and short-term mortality in patients with infection-associated disseminated intravascular coagulation: a cohort study.

Background: Severe infection is the most frequent disease underlying disseminated intravascular coagulation (DIC). To improve understanding of the clinical course, we examined the association between infection type and short-term mortality in patients with infection-associated DIC.
Methods: Patients with infection-associated DIC registered in the Danish Disseminated Intravascular Coagulation (DANDIC) cohort were categorised by infection type: pulmonary, intra-abdominal, urogenital, others, multiple infection sites and unknown foci.
While key for pathogen immobilization, neutrophil extracellular traps (NETs) often cause severe bystander cell/tissue damage. This was hypothesized to depend on their prolonged presence in the vasculature, leading to cytotoxicity. Imaging of NETs (histones, neutrophil elastase, extracellular DNA) with intravital microscopy in blood vessels of mouse livers in a pathogen-replicative-free environment (endotoxemia) led to detection of NET proteins attached to the endothelium for months despite the early disappearance of extracellular DNA.

Toxic shock syndrome secondary to Group A infection is a rare but serious cause of women's morbidity and mortality which can easily be misdiagnosed. A 37-year-old woman presented to the emergency department in a state of shock after a two-day history of abdominal pain, fever, diarrhoea and green vaginal discharge. Following extensive investigations, she was proved to have septic shock secondary to Group A Despite receiving intravenous antibiotics, she required explorative laparotomy, which proceeded to subtotal hysterectomy and bilateral salpingectomy.

Microangiopathic hemolytic anemia (MAHA) is a condition characterized by intravascular fragmentation of red blood cells, leading to the characteristic finding of schistocytes on a peripheral blood smear. The differential diagnoses of MAHA include thrombotic thrombocytopenic purpura (TTP), hemolytic-uremic syndrome (HUS), disseminated intravascular coagulation (DIC), idiopathic thrombocytopenic purpura (ITP), infections, malignancies, and solid organ transplantation. The commonly associated malignancies with MAHA are gastric, breast, prostate, lung, and lymphoma.

Background: Platelet adhesion to collagen, a critical initial step in thrombus formation, remains an underexplored therapeutic target in thrombosis. Current disease treatment strategies primarily focus on platelet activation and aggregation, often overlooking the crucial initial adhesion phase. Reynoutria japonica (Huzhang, HZ), utilized in traditional Chinese medicine to enhance blood circulation and resolve blood stasis, lacks comprehensive insights into its active components and their anti-thrombotic mechanisms.
