Study Summary

This trial is testing different ways to treat people who have lost their spleen in an accident. The different ways are: nonoperative management, embolization, or removal of the spleen. The study is also investigating the antibody response to pneumococcal vaccine in patients undergoing these modes of therapy.

Who is the study for?
This trial is for adult trauma patients aged 18 to 65 who have sustained a splenic injury. It's not open to those under 18 or over 65, and if someone initially managed without surgery needs embolization or spleen removal later, they'll be taken out of the study.Check my eligibility
What is being tested?
The study is examining how well patients with splenic injuries respond to the Pneumovax-23 vaccine. This response will be compared across three different treatments: nonoperative management, embolization, and spleen removal.See study design
What are the potential side effects?
While specific side effects are not listed here, vaccines like Pneumovax-23 can typically cause soreness at the injection site, mild fever, muscle pain, and in rare cases more serious allergic reactions.

Trial Design

3Treatment groups
Active Control
Group I: NonoperativeActive Control1 Intervention
Pneumococcal vaccine (Pneumovax-23) will be administered within 72 hours of injury. Baseline antibody levels will be drawn at the time of vaccine administration, with response levels being drawn 4 weeks later.
Group II: AngioembolizationActive Control1 Intervention
Pneumococcal vaccine (Pneumovax-23) will be administered 14 days after embolization. Baseline antibody levels will be drawn at the time of vaccine administration, with response levels being drawn 4 weeks later.
Group III: SplenectomyActive Control1 Intervention
Pneumococcal vaccine (Pneumovax-23) will be administered 14 days after splenectomy. Baseline antibody levels will be drawn at the time of vaccine administration, with response levels being drawn 4 weeks later.
