Sex differences in the time trends of sepsis biomarkers following polytrauma.
Sci Rep
January 2025
Department of Trauma Surgery, University Hospital Zurich, 8091, Zurich, Switzerland.
Sepsis is a major cause of death in polytrauma patients, with delayed antibiotics increasing mortality. Although biological sex influences immune function and disease outcomes, gender-specific differences in inflammatory response and sepsis progression remain underexplored. This study examined the time-dependent behavior of C-reactive protein (CRP), procalcitonin (PCT), and white blood cell count (WBC) in male and female polytrauma patients to evaluate their predictive value for sepsis.

Objectives: To evaluate the role of serum procalcitonin (PCT) as a diagnostic tool to differentiate bacterial sepsis from flare-ups during febrile episodes in children with known rheumatic disorders compared to other inflammatory markers like C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR).
Methods: Previously diagnosed patients with known rheumatic disorders presenting in emergency or outpatient departments with febrile episodes were included in the study. Blood samples were collected upon admission to test for signs of infection, including serum PCT levels with routine laboratory and radiological tests.
Advances of immunosensors based on noble metal composite materials for detecting procalcitonin.

Procalcitonin (PCT) is a reliable biomarker for diagnosing and monitoring bacterial infections and sepsis. PCT exhibits good stability both in vivo and in vitro, and its levels drastically increase in response to bacterial infection or inflammatory reactions in the human body, making it a dependable indicator for sepsis diagnosis and monitoring with significant implications for clinical diagnosis and treatment guidance. Currently, immunosensors are widely utilized in PCT detection due to their high sensitivity and low detection limits.

Antibiotics (Basel)

Department of Microbiology, "Cantacuzino" Institute, "Carol Davila" University of Medicine and Pharmacy, 020021 Bucharest, Romania.
Antimicrobial resistance is one of the main threats to public health, with multidrug-resistant (MDR) pathogens on the rise across continents. Although treatment guidelines generally recommend antimicrobial therapy for acute complicated diverticulitis, they do not specify treatment pathways according to local or national resistance profiles. There is sparse data regarding specific pathogens involved in Hinchey II-IV patients who undergo surgery.

Department of Gastroenterology, Christian Medical College, Vellore, Tamil Nadu, India.
Background: Differentiating infections from sterile inflammation is crucial in early AP management.
Aim: This study aimed to assess the capability of Neutrophil-to-Lymphocyte Ratio (NLR) and procalcitonin to differentiate between sterile inflammation and infections in the first week of AP and to analyze the source, microbiological profile, and impact of infections in AP.
Methods: Consecutive patients presenting within 5 days of symptom onset were included.
