Immunosuppressive therapy is necessary to prevent transplant rejection, also in the case of pregnant transplant recipients, which means that the medications may influence foetal development. An ideal immunosuppressive regimen should provide for excellent immunosuppression with minimal or no side effects. Yet, current immunosuppressive therapy regimens commonly used in clinical applications fail to meet this criterion. One of the complications caused by immunosuppressive drugs are mineralisation disorders in hard tissues. Therefore, in this study, we evaluated the impact of three regimens of immunosuppressive therapy used after renal transplantation, containing medications which are indicated (prednisone, cyclosporine A (CsA), tacrolimus (Tc)) and contraindicated (mycophenolate mofetil (MMF), everolimus) during pregnancy on the concentrations of essential minerals, calcium (Ca), phosphorus (P) and magnesium (Mg), affecting normal bone formation. The samples were analysed using inductively coupled plasma optical emission spectrometry (ICP-OES, ICAP 7400 Duo, Thermo Scientific) equipped with a concentric nebuliser and a cyclonic spray chamber. The immunosuppressive regimens under study had no effect on the levels of Mg and P, but they did contribute to increased bone Ca levels in the mothers in the group receiving Tc, MMF and prednisone and group receiving CsA, everolimus and prednisone. In the offspring of tested mother rats, immunosuppressive therapies may affect Mg levels in hard tissues. The immunosuppressive regimens administered at therapeutic doses are harmful to rat foetuses as evidenced by the small number or lack of offspring in the tested groups.
