What this trial studies

This research project aims to investigate the early immune responses to bacterial and viral infections using human spleen tissue samples obtained from patients undergoing elective surgery. By utilizing a spleen perfusion model developed from pig organs, the study will analyze how bacteria replicate in spleen cells and how these cells respond to infections. The project will involve ex vivo organ perfusion and infection experiments, with the resulting tissue and cell cultures being preserved for future research on therapeutic interventions. The goal is to enhance understanding of the immune response in humans, which could inform treatment strategies for severe infections.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients aged 18-80 undergoing elective surgery for pancreatic lesions who have spleen tissue available for research.

Not a fit: Patients with acute invasive bacterial or viral infections will not benefit from this study as they are excluded from the surgical procedures involved.

Why it matters

Potential benefit: If successful, this research could lead to improved prevention and treatment strategies for severe bacterial and viral diseases.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in understanding immune responses, suggesting potential for success.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* The samples included in this project will be from patients undergoing elective surgery in the HPB Unit of the Leicester General Hospital.
* Spleen samples from radical surgery are adult age (18-80 years)
* Presence of splenic tissue in the discarded material after hepato-pancreato-biliary surgery.

Exclusion Criteria:

* The main exclusion criterion is acute invasive bacterial and viral infection, but these patients are automatically excluded from major surgery.
* Samples from patients treated with antibiotics prior to explant or surgery will not be excluded, but samples will have to be tested for residual antibiotic activity.
