Gastrointestinal pathological changes in stem cell transplant patients

Area of Science:

• Gastroenterology
• Hematology
• Oncology

Background:

• Hematopoietic stem cell transplantation (HSCT) is a complex procedure with potential gastrointestinal complications.
• The landscape of gastrointestinal diseases in HSCT recipients has evolved significantly in recent years.

Purpose of the Study:

• To review current knowledge on gastrointestinal diseases in HSCT patients.
• To highlight newly described gastrointestinal conditions and their management.

Main Methods:

• Literature review of recent opinions and findings.
• Synthesis of information on graft-versus-host disease, infections, and novel entities.

Main Results:

• Gastrointestinal graft-versus-host disease remains a significant concern.
• Opportunistic infections and newly described conditions like mycophenolate-mofetil-related injury and cord colitis syndrome are increasingly recognized.
• Specific treatments are available for several of these rare gastrointestinal diseases.

Conclusions:

• Comprehensive clinical information is vital for interpreting gastrointestinal endoscopic biopsies in HSCT patients.
• Clinicians and histopathologists must be aware of rare gastrointestinal diseases specific to this population.
• Early recognition and awareness of these conditions can lead to improved patient outcomes.
