Solid organ transplant-associated acute graft-versus-host disease

Area of Science:

• Immunology
• Transplantation Medicine
• Oncology

Background:

• Graft-versus-host disease (GVHD) post-solid organ transplant (SOT) is a rare, life-threatening complication.
• Incidence varies by transplant type, notably higher in liver and small bowel recipients.
• Multisystemic involvement and high mortality rates underscore the severity of this condition.

Purpose of the Study:

• To review the current understanding of pathogenesis, diagnosis, and treatment of SOT-associated GVHD.
• To highlight the diagnostic criteria and clinical presentation.
• To discuss current management strategies, including prophylaxis and treatment.

Main Methods:

• Literature review of pathogenesis, clinical presentation, diagnosis, and treatment of SOT-associated GVHD.
• Analysis of incidence rates based on organ transplant type.
• Summary of diagnostic methods including clinical symptoms, pathology, and lymphoid chimerism.

Main Results:

• SOT-associated GVHD presents with fever and rash, rapidly progressing to multisystemic disease.
• Liver transplant recipients face over 75% mortality, often due to bone marrow failure complications like infections and hemorrhage.
• No standard treatment exists; management focuses on prophylaxis and prompt intervention.

Conclusions:

• SOT-associated GVHD requires timely diagnosis and management due to its high lethality.
• Further research into standardized treatment protocols is warranted.
• Understanding pathogenesis is key to improving patient outcomes.
