Transplantation
-
Survival rates after lung transplantation are the lowest among solid organ transplantations. Long-term survival is limited by the development of chronic rejection, known as bronchiolitis obliterans syndrome (BOS). Risk factors, such as acute rejection and cytomegalovirus infection, contribute to the development of BOS. ⋯ This review shows that there may be involvement of genetic polymorphisms in the development of BOS. Genetic risk profiling of lung transplant recipients could be a promising approach for the future, enabling individualized risk stratification and personalized immunosuppressive treatment after transplantation. Further studies are needed to define risk alleles.
