[Successful pregnancy in a patient with systemic lupus erythematosus on hemodialysis]. / Gestación con éxito en una paciente con lupus eritematoso sistémico en hemodiálisis.

We report a twenty-nine-year-old patient, on renal replacement treatment (including 2 kidney transplants) since she was 11 years old, because of systemic lupus erythematosus. The patient became pregnant on hemodialysis, concluding the pregnancy successfully. The evolution and management of pregnancy were described and the related literature was revised. We concluded that, although pregnancy on hemodialysis and/or systemic lupus erythematosus patients involves a high risk for the mother and the fetus that makes advisable contraception, an increase in success in pregnancies in systemic lupus erythematosus patients on remission during the previous months, has been recently observed. Moreover, the increase of frequency and duration of hemodialysis sessions, has improved the neonatal survival around the 50% in pregnancies on dialysis. We emphasize the difficulty to maintain the mother's hemoglobin at an adequate target, as well as the high frequency of fetal prematury.
