Contraception in women after organ transplantation

INTRODUCTION

Organ transplantation has improved the quality and length of life for many people suffering from end-stage diseases, among them women of reproductive age. Therefore, it has made pregnancy possible for those previously unable to conceive. Nevertheless, conception itself should be desired and properly timed in these specific patients to ensure the best possible perinatal outcome.

OBJECTIVE

The objective of the study was to assess whether female graft recipients apply proper family planning methods and use effective contraception.

METHODS

In a single-center, observational study, information was collected using a self-administered questionnaire distributed among 100 female graft recipients (post-transplant group [TG]) and 67 healthy female volunteers (control group [CG]). The survey covered data regarding present menstrual patterns, sexual activity, gynecological counseling, and contraceptive methods used.

RESULTS

Female graft recipients were more sexually active after than before transplantation (87% vs 64%, P = .0001) and equally active as controls. Sexually active post-transplantation patients used contraception less frequently than sexually active controls (51.72% vs 82.76%, P < .0001). Condoms were the most frequently used method in TG, and oral contraception in CG. Oral contraception was used more rarely by counseled graft recipients than by counseled controls (3.9% vs 60.7%, P < .0001). After counseling, intrauterine device usage increased and oral contraception usage decreased in TG. Among women with chronic diseases, intrauterine device was used more often in TG (4% vs 0%), whereas oral contraception was used more often in CG (8.3% vs 50%, P < .0001).

CONCLUSIONS

Despite the fact that post-transplantation women of reproductive age have many indications for highly effective contraception, only few of them actually use it. Contraceptive counseling has to be included as part of routine post-transplantation care by all health professionals involved in the management of female graft recipients of reproductive age.

Intrauterine hypotrophy and premature births in neonates delivered by female renal and liver transplant recipients

BACKGROUND

Neonates born to mothers, who underwent organ transplantation require close medical monitoring. It is unknown how chronically diseased mother's organs or immunosuppressive drugs affect fetal growth and development; some immunosuppressants are teratogenic and contraindicated during pregnancy. The aim of this study was to determine the prevalence of prematurity and intrauterine growth restriction in neonates born to women who have undergone renal or liver transplantation.

METHODS

Our retrospective analysis identified 53 (25 renal and 28 liver) cases of neonates delivered by female graft recipients between January 2005 and December 2009. Hypotrophy was defined as a birth weight<10th percentile for gestational age. We excluded newborns diagnosed with severe hypotrophy (<5th percentile).

RESULTS

Neonates born prematurely were predominate in the renal (16/25, 64%), but less than half of the liver cohort (13/28, 46%). Hypotrophy less than the 10th percentile was noted significantly more often among renal than liver recipients; 36% versus 14% (P<.05). Severe hypotrophy was also observed significantly more often among renal than liver transplant neonates: 28% versus 3.6% (P<.001).

CONCLUSIONS

Compared with liver insufficiency, chronic kidney diseases have stronger effects on the fetus, leading to adverse neonatal complications. A greater prevalence of preterm births, as well as hypotrophic newborns, especially less than the 5th percentile, was observed among neonates delivered by mothers after kidney transplantation.

Pregnancy outcomes among female recipients after liver transplantation: further experience

INTRODUCTION

Liver transplantations give female recipients an ability to carry pregnancies successfully. However, solid organ transplantations exacerbate the pregnancy including maternal and neonatal outcomes. The aim of our study was to evaluate and identify the obstetric outcomes in women with a prior liver transplantation.

METHODS

We analyzed all pregnant woman who had undergone a prior liver transplantation and afterward delivered from 2001 to 2011. Complete data were assessed in 39 deliveries and 40 live births. Three women were pregnant twice after liver transplantation.

RESULTS

The mean gestational age at birth measured 37.2±2.2 weeks. The most common obstetric complications were premature labor (12/39,30.8%), hypertension (10/39, 25.6%), and symptomatic urinary tract infections (7/39, 18%). Other complications were pregestational diabetes (n=1), cholestasis (n=3), and of severe anemia treated with blood transfusions (n=2). The mean time from organ transplantation to delivery was 67.6±47.2 months. Acute graft rejections occurred among pregnant women 7.7% (3/39) of studied. Only 8 (20.5%) deliveries were finished vaginally. Infants small for gestational age were diagnosed in 20% (8/40). One case displayed a congenital urinary tract malformation. None of the neonates died neonatally.

CONCLUSIONS

Pregnancies are possible after liver transplantation and likely end with successful maternal and newborn outcomes. Some cases experience an increased risk of obstetric complications. Therefore, posttransplant pregnancies must be regularly monitored with a multidisciplinary approach.
