Resumen
Se presenta un paciente con enfermedad renal crónica e hipoparatiroidismo posquirúrgico tratado con calcitriol y carbonatocálcico, a quien se le practicó trasplante renal. Meses más tarde revela hipocalcemia severa con hiperfosfatemia refractariaa altas dosis de calcitriol y carbonato cálcico, optándose por utilizar teriparatida un fragmento aminoterminal (1-34) sintéticode la paratohormona, con mejoría transitoria. Luego desarrolla resistencia a la misma a pesar de su utilización a dosis noconvencionales (120 μgs/día), siendo necesaria su suspensión y el uso de nuevo de dosis muy altas de calcitriol y carbonatocálcico para lograr estabilización. La hiperfosfatemia desencadenada fue manejada posteriormente con quelantes de fosfatosvía oral.
