Background: Sepsis typically results in enhanced coagulation system activation and microthrombus formation. Microparticle (MP) production promotes coagulation and enhances pro-coagulation. This study investigated how circulating MP levels and tissue factor-bearing MP (TF+-MP) activity caused coagulation in patients with septic disseminated intravascular coagulation (DIC).
Methods: Thirty patients with septic DIC and 30 healthy controls were studied from December 2017 to March 2019. Patient blood samples were collected at enrolment (day 1) and on days 3 and 5; DIC scores and Sequential Organ Failure Assessment (SOFA) scores were recorded. TF+-MP activity was measured using TF-dependent factor Xa generation experiments. Circulating MP concentrations were determined by MP capture assay. Clotting factor activity, antithrombin level, soluble thrombomodulin, and serum tissue factor pathway inhibitor (TFPI) concentrations were measured.
Results: Patients with septic DIC had lower circulating MP levels than healthy control patients. Circulating MP levels in patients with septic DIC were positively correlated with DIC scores and negatively correlated with coagulation factors, but TF+-MP activity did not correlate with clotting factor levels and TFPI.
Conclusions: In patients with septic DIC, circulating MP levels are important in promoting coagulation activation and increasing clotting factor consumption. TF+-MP activity may not be the main form of active TF.

Sepsis is a major cause of morbidity and mortality worldwide. Among the various types of end-organ damage associated with sepsis, hepatic injury is linked to significantly higher mortality rates compared to dysfunction in other organ systems. This study aimed to investigate potential biomarkers of hepatic injury in sepsis patients through a multi-center, case-control approach.

Introduction-Aim: Postpartum septic osteoarthritis is a rare but serious condition often misdiagnosed due to overlap with common postpartum symptoms like pelvic pain and joint stiffness. This case series aims to describe the clinical, bacteriological, and radiological characteristics of postpartum septic osteoarthritis, as well as the treatment approaches and patient outcomes. Methods: A retrospective case series was conducted at Farhat Hached University Hospital, from 2006 to 2022, involving patients with confirmed postpartum septic osteoarthritis.

Sepsis often leads to vasoplegia and a hyperdynamic cardiac state, with treatment focused on restoring vascular tone. However, sepsis can also cause reversible myocardial dysfunction, particularly in the elderly with pre-existing heart conditions. The Surviving Sepsis Campaign Guidelines recommend using dobutamine with norepinephrine or epinephrine alone for patients with septic shock with cardiac dysfunction and persistent hypoperfusion despite adequate fluid resuscitation and stable blood pressure.

This study aimed to investigate the clinical value of glucocorticoids in patients with neutropenic severe pneumonia at moderate to high risk according to the Pneumonia Severity Index (PSI) in patients with hematologic diseases. Clinical data were collected from 534 patients at the Fujian Medical University Union Hospital from October 2016 to December 2018. We evaluated the changes in inflammatory cytokines, treatment failure, in-hospital mortality, and other outcomes, adjusting for potential confounders through propensity score matching.
