Background: Kidney transplantation is associated with fertility restoration in more than 50% of women with chronic kidney disease. Pregnancy after transplantation may affect women’s health and fetal development, with higher rates of abortion, fetal growth restriction, and neonatal deaths. Twin pregnancy is a condition of high-risk for adverse maternal and perinatal outcomes, and its occurrence in women with previous kidney transplantation is rare. Case: 32-year-old woman, recipient of living donor kidney transplantation, with a history of one pregnancy prior to transplantation, with current normal allograft function and no use of contraceptive method. At ten weeks of amenorrhea, ultrasound investigation showed a dichorionic diamniotic twin pregnancy. The following evaluation showed Chiari type II features in one fetus, and no detectable abnormality in the other one. There was appropriate blood pressure control with no need for an antihypertensive drug, and renal function remained normal without proteinuria. Calcium and a low dose of acetylsalicylic acid were used as preeclampsia prophylaxis. At 33 weeks of gestation, she presented premature rupture of membranes with spontaneous preterm labor. A cesarean section was performed due to the breech presentation of the first fetus. The patient persisted with normal graft function and without graft rejection during follow-up. Discussion and conclusion: Twin pregnancies after kidney transplantation are rare, and it is most frequently associated with preterm birth. We reported a successful twin pregnancy after kidney transplantation, with good perinatal and maternal outcomes, and without graft rejection or dysfunction.
Background:The kidney transplant is a foreign body in the patient's organism, thus constituting a procedure that triggers an intense inflammatory reaction. Objective: To assess the clinical characteristics of people undergoing kidney transplantation with immune sensitization. Methodology: A descriptive, documentary, and retrospective study with a quantitative approach to data treatment and analysis was carried out between June and August 2019. Results: The association between donor-specific antibodies (DSA) and graft dysfunction (p < 0.03) and pregnancy (p < 0.04) was statistically significant. The occurrence of complications was also associated with the length of hospital stay (p < 0.00) and serum creatinine levels in the first week after transplant (p < 0.006). Conclusion:The clinical characterization showed that most patients had graft dysfunction, DSA, and complications, meaning that transplanted patients require a critical and individualized follow-up.
Costa do Nascimento. ResumoO armazenamento de tecido placentário, com coleta sistemática, poderá ampliar a possibilidade de pesquisa translacional na área. Uma complicação que tem chamado a atenção mundialmente é a epidemia por zika vírus (ZIKV) e associação com microcefalia e malformações fetais. Ainda não se sabe os mecanismos de transmissão transplacentária e a coleta destas placentas é uma necessidade, para colaborar com a investigação clínica e diagnóstico de casos suspeitos e também, para possibilitar estudos visando a compreensão da fisiopatologia da doença. Outra prioridade em obstetrícia, com papel central da placenta e etiologia ainda pouco esclarecida é a Préeclâmpsia, doença que acomete até 10% de todas as gestações, sendo uma das principais causas de morbidade e mortalidade materna no Brasil. Para possibilitar a investigação da fisiopatologia destas condições e futuramente de demais doenças, a criação de um biobanco de placenta no CAISM representa um passo importante.
