Close microbiological monitoring versus daily ceftriaxone to prevent infections after stem cell transplant

Comparison of Enhanced Molecular-Level Microbiological Surveillance and Ceftriaxone Prophylaxis in Patients Undergoing Hematopoietic Cell Transplantation: A Randomized, Prospective Medical Experiment

Not applicable Interventional Pomeranian Medical University Szczecin · NCT07308457

This project tests whether careful microbiological monitoring without preventive antibiotics works as well as daily ceftriaxone to prevent infections in adults receiving hematopoietic stem cell transplants.

What this trial studies

Adults undergoing autologous or allogeneic hematopoietic stem cell transplantation are randomly assigned to receive either daily ceftriaxone prophylaxis or no preventive antibiotics with intensified monitoring. The monitoring arm uses continuous temperature sensors and frequent microbiological testing, including genetic methods to identify bacteria and resistance markers, with standard antibiotics started if infection signs appear. Researchers will compare rates of infections, bloodstream infections, pneumonia, severe sepsis, antibiotic resistance patterns, blood count recovery, and length of hospital stay. The trial is conducted at a single transplant center and follows participants through the peri-transplant neutropenic period.

Who should consider this trial

Good fit: Adults (≥18 years) receiving autologous or allogeneic hematopoietic stem cell transplants who have been free of active infection for at least two weeks and can provide informed consent.

Not a fit: Patients with ongoing antibiotic therapy (except cotrimoxazole), fever of unknown origin, recent active infection, or other exclusion criteria are not likely to be eligible or to benefit from the monitoring-only strategy.

Why it matters

Potential benefit: If successful, this approach could let patients avoid routine preventive antibiotics while keeping infection rates low and reducing the development of antibiotic resistance.

How similar studies have performed: Previous trials have shown that antibiotic prophylaxis can reduce some infections during neutropenia but often increases resistance, while intensive microbiological surveillance without routine prophylaxis has been less well studied.
