Background: S100A12 is related to acute brain injury and inflammation. We investigated the clinical prognostic value of serum S100A12 in patients with severe traumatic brain injury (sTBI).
Methods: Serum S100A12, S100B, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) concentrations were measured in 102 healthy controls and 102 sTBI patients. We recorded 30-day mortality and in-hospital major adverse events (IMAEs) including acute lung injury, acute traumatic coagulopathy, progressive hemorrhagic injury and posttraumatic cerebral infarction. Trauma severity was assessed by admission Glasgow Coma Scale scores.
Results: When compared to the controls, serum S100A12, S100B, CRP, IL-6 and TNF-α concentrations were significantly increased in the patients. Serum concentrations of S100A12 significantly correlated with admission Glasgow Coma Scale scores and serum concentrations of S100B, CRP, IL-6 and TNF-α. Patients with any IMAEs or non-survivors within 30 days had obviously higher serum concentrations of S100A12, S100B, CRP, IL-6 and TNF-α than other remaining ones. Serum S100A2 was independently associated with IMAEs and 30-day mortality and overall survival. Receiver operating characteristic curve analysis showed that S100A12 concentrations had significant discriminatory ability for patients at risk of any IMAEs and death within 30 days.
Conclusion: S100A12 might be associated with brain inflammation and evaluation of serum concentrations of S100A12 could be helpful in the early prognostic prediction in sTBI patients.

Inflammatory biomarker analysis confirms reduced disease severity in heterozygous patients with familial Mediterranean fever.
RMD Open
November 2024
Pediatric Rheumatology and Immunology, University Medicine, Albert-Schweitzer-Campus 1, Munster, Germany.
Article Synopsis
- Familial Mediterranean fever (FMF) is a genetic condition marked by inflammation episodes, usually treated with colchicine to prevent complications like amyloid A amyloidosis, but its necessity for heterozygous patients is debated.* -
- A study analyzed 747 FMF patients' demographic and inflammatory biomarker data, revealing that heterozygous patients generally exhibited lower inflammatory markers compared to those with more severe genetic variants.* -
- The findings suggest that certain biomarkers (S100A8/A9 and S100A12) can indicate disease activity, and some heterozygous patients may be eligible to safely stop colchicine treatment.*
Neutrophil and mononuclear leukocyte pathways and upstream regulators revealed by serum proteomics of adult and juvenile dermatomyositis.
Arthritis Res Ther

Article Synopsis
- The study aimed to identify differences in serum protein levels between adult and juvenile dermatomyositis (DM and JDM) patients compared to healthy controls to find potential biomarkers for disease activity.
- A multiplex immunoassay was used to analyze serum protein expression from 17 active DM and JDM patients, revealing 78 out of 172 proteins were differentially expressed, with specific proteins highlighted for each patient group.
- The analysis showed activated signaling pathways in both DM and JDM, with several proteins correlating with disease activity, suggesting potential candidates for monitoring the condition's severity.
Amlexanox reduces new-onset atrial fibrillation risk in sepsis by downregulating S100A12: a Mendelian randomization study.
Front Cardiovasc Med
October 2024
Department of Anesthesiology, The First Affiliated Hospital of Fujian Medical University, Fuzhou, China.
Background: Sepsis is characterized by high morbidity and mortality rates, alongside limited therapeutic efficacy. Atrial fibrillation (AF), the most common arrhythmia, has been closely linked to sepsis in prior research. However, the specific mechanisms through which sepsis leads to new-onset AF remain poorly understood.

Article Synopsis
- Atopic dermatitis (AD) is a widespread chronic skin condition, but the link between metabolites and its development hasn't been fully understood yet.
- * This study investigates the genetic connections between metabolites and AD, focusing on how amino acid metabolites like N6-methyllysine influence the disease through the inflammatory protein S100A12.
- * Results showed that S100A12 is associated with various immune cells in AD-affected skin and is a key mediator between certain metabolites and the onset of AD.

Objective: We sought to identify differentially expressed proteins in serum, plasma, and plaque samples of patients with carotid atherosclerotic lesions.
Methods: We performed a systematic review of the proteomic profile of serum, plasma, and plaque samples of patients with carotid artery disease. We included full-length peer-reviewed studies of adult humans and reported them using PRISMA guidelines.
