Randomized Controlled Trial Multicenter Study
Hemoperfusion using the LPS-selective mesoporous polymeric adsorbent in septic shock: a multicenter randomized clinical trial.
Extracorporeal hemoperfusion (EHP) may improve the course and outcomes of patients with septic shock by targeting cytokines or bacterial endotoxins (lipopolysaccharide [LPS]). Here, we present the results of a multicenter randomized controlled trial ( clinicaltrials.gov/ct2/show/NCT04827407 ) to assess the efficiency and safety of Efferon LPS hemoperfusion cartridges engineered for multimodal targeting LPS, host-derived cytokine, and damage-associated molecule pattern molecules. Patients with intra-abdominal sepsis (IAS) and septic shock (Sepsis-3) were subjected to EHP procedures (n = 38). ⋯ Early 3-day mortality was significantly reduced in the Efferon LPS versus control group; however, no significant improvements in survival in 14 and 28 days were revealed. Laboratory tests showed rapidly decreased levels of LPS, procalcitonin, C-reactive protein, IL-6, creatinine, leukocytes, and neutrophils only in the Efferon LPS group. Results demonstrate that EHP with Efferon LPS is a safe procedure to abrogate septic shock and normalize clinical and pathogenically relevant biomarkers in patients with IAS.

Comparative Study
Persistent pulmonary hypertension of the newborn and smoking and aspirin and nonsteroidal antiinflammatory drug consumption during pregnancy.
Prenatal causation of persistent pulmonary hypertension of the newborn (PPHB) is suggested by a specific pattern of pulmonary vascular remodeling observed immediately after birth in some infants with fatal PPHN. The goal of this study was to determine whether PPHN is associated with fetal exposure to: (1) tobacco and marijuana smoking (ie, contributors to fetal hypoxemia), (2) consumption of aspirin and other nonsteroidal antiinflammatory drugs (ie, inhibitors of prostaglandin synthesis), and (3) cocaine use (ie, a contributor to vasospasm). ⋯ Maternal consumption of nonsteroidal antiinflammatory drugs and aspirin during pregnancy or the reasons these drugs were ingested seem to contribute to an increased risk of PPHN.
