AI Article Synopsis

  • This study investigates the links between certain cytokines and genetic variations in patients undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass, particularly focusing on how these factors relate to postoperative complications.
  • Researchers analyzed specific gene polymorphisms and measured cytokine levels at various times, finding significant associations between certain genetic markers and adverse clinical outcomes.
  • The findings suggest that testing for IL6 and IL10 gene variations could help identify patients at higher risk of complications and guide strategies for better management of inflammation during and after surgery.

Article Abstract

Objective: Cardiopulmonary bypass remains associated with significant morbidity and mortality, in part caused by a systemic inflammatory response that is unpredictable and variable among patients. Several limited studies have suggested associations of cytokine plasma levels or gene polymorphisms with outcome after cardiopulmonary bypass. The present study was to determine the relationships between several circulating cytokines and their polymorphisms (single nucleotide polymorphisms), and the occurrence of postoperative clinical events in patients who underwent coronary artery bypass grafting under cardiopulmonary bypass.

Methods: Patients were genotyped for single nucleotide polymorphisms of LTA (Cys13Arg, +252A>G), TNF (-308G>A), IL6 (-597G>A, -572G>C, -174G>C), IL10 (-592C>A, c.∗117C>T), and APOE (Cys112Arg, Arg158Cys). Serum samples were collected preoperatively, immediately after cardiopulmonary bypass, and at different postoperative time points to measure cytokine serum levels by enzyme-linked immunosorbent assay. The clinical end point was the composite of postoperative death, low cardiac output syndrome, myocardial infarction, sepsis, and acute renal insufficiency.

Results: Single nucleotide polymorphisms IL6-572GC+CC/IL10-592CC were associated with the clinical end point (P=.032 and P=.009, respectively). In addition to preoperative clinical conditions, the other factor associated with the clinical end point was interleukin-10 plasma levels 24 hours after surgery (P=.017). On the basis of these results, a predictive model of postoperative complications after coronary artery bypass grafting was created.

Conclusions: Our data suggest that focused genetic testing of the IL6-572G>C and IL10-592C>A single nucleotide polymorphisms might be a tool for identifying patients at the highest risk of poor tolerance to the inflammatory response to cardiopulmonary bypass and for implementing strategies to mitigate it, provided the generalization of these tests makes them reasonably affordable and thus favorably shifts their cost-to-benefit ratio.

Background: ASD is a relatively rare subset among patients with situs inversus dextrocardia with concordant AV connection and a minimally invasive approach in dextrocardia has yet to be standardized. The present case describes a case surgical closure of ostium secundum ASD by left mini-thoracotomy approach in patient with dextrocardia and situs inversus.

Case Presentation: The present case describes a 44-year female patient of ostium secundum ASD in dextrocardia with situs inversus.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

Introduction: The effects of remimazolam (Re) in combination with andrographolide (AP) on learning, memory, and motor abilities in rats following cardiopulmonary bypass (CPB) surgery were studied.

Methods: We hypothesized that the combination of Re and AP could improve postoperative cognitive dysfunction (POCD) in rats after CPB by modulating nervous system inflammation. Cognitive function was assessed using the Morris Water Maze test, and the concentrations of tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) in serum were measured by enzyme-linked immunosorbent assay (ELISA).
