Rh(D) Alloimmunization Risk after Rh(D)-incompatible Solid Organ Transplantations in Rh(D)-Negative Recipients

Pdf Summary

This brief report discusses the risk of Rh(D) alloimmunization after Rh(D)-incompatible solid organ transplantations in Rh(D)-negative recipients. The study reviewed 35 patients who underwent such transplants, where the patients were divided into groups based on RhIG administration. It was found that anti-D was not detected in the nonadministered group, suggesting RhIG prophylaxis may not offer clinical benefits. The study highlights the lower rates of alloimmunization in immunosuppressed patients and questions the necessity of routine RhIG administration, especially for male and menopausal female patients. The report also touches on the risks of RhIG administration, such as potential immune complex formation. The authors recommend further studies to solidify these findings and establish optimal RhIG prophylaxis strategies in Rh(D)-incompatible transplantations. The paper suggests a shift in practice to reconsider routine RhIG administration in these cases. Additional research is needed to explore the impact of immune complexes on patient outcomes and rejection-free survival rates. Despite the need for more extensive studies, the current findings indicate a low risk of Rh(D) alloimmunization in Rh(D)-incompatible transplant recipients and question the standard practice of RhIG administration in these cases.
