The first known post-transplant pregnancy occurred in 1958 in a recipient who had received a kidney from her identical twin sister. Successful post-transplant pregnancies have since been reported among recipients of all types of solid organ transplants.
In 1991, a resource for transplant recipients and their healthcare providers was established by Drs. Vincent Armenti and Michael Moritz at Thomas Jefferson University in Philadelphia, through the creation of the National Transplantation Pregnancy Registry.
NTPR Reported Pregnancy Outcome Data
**Mycophenolic acid and mycophenolate mofetil, two commonly prescribed immunosuppressive medications, should be avoided whenever possible during pregnancy.**
- Recent studies show that prednisone, azathioprine, cyclosporine and tacrolimus use by recipients need not discourage breastfeeding.
- There are only limited data on breastfeeding safety for recipients taking mycophenolic acid products, sirolimus, everolimus and belatacept.
- Testing serum and breast milk can be undertaken to address concerns about infant exposure through breast milk to immunosuppression medications.
Factors to consider in the timing of pregnancy (AST, 2005):
- No rejection in the past year
- Adequate and stable graft function
- No acute infections that impact fetus
- Maintenance immunosuppression at stable dosing
