TOG CPD. These are open access. They are ‘True/False’.

With regard to renal transplant,

1.     most recipients have a successful pregnancy outcome.

2.     pregnancy is associated with a 10% reduction in GFR in recipients with prepregnancy eGFR >90 ml/ min/1.73m2 .

3.     hypertension complicates pregnancy in over 50% of recipients who did not require antihypertensive treatment prior to pregnancy.

4.     proteinuria is a predictor of poor pregnancy outcome in recipients.

5.     the risk of damage to the allograft at caesarean delivery is about 1%.

6.     a positive serological screening test for aneuploidy in recipients is a recognised consequence of impaired renal function.

7.     superimposed pre-eclampsia in recipients has defined diagnostic criteria.

8.     erythropoietin requirements in recipients fall in pregnancy.

9.     breastfeeding is safe in recipients on angiotensin converting enzyme inhibitors.

10.   conception is not advised in recipients within the first year following transplantation.

11.   continuous electronic fetal monitoring is recommended during labour in recipients.

12.   the progesterone implant is a safe form of postpartum contraception in recipients.

Women who have donated a kidney,

13.   are at increased risk of gestational hypertension.

Combined kidney-pancreas transplant recipients,

14.   have a higher risk of gestational diabetes than kidney transplant recipients.

Liver transplant recipients,

15.   have a lower risk of pregnancy complications than renal transplant recipients.

With regard to pregnancy in cardiothoracic transplant recipients,

16.   lung transplant recipients have the highest risk of adverse outcome of all solid organ transplants.

17.   due to denervation, the transplanted heart responds poorly to the physiological changes of pregnancy.

18.   cardiothoracic transplant recipients should be delivered by caesarean section.

Regarding medications prescribed in patients with solid organ transplants,

19.   tacrolimus levels require monitoring during pregnancy.

20.   warfarin is safe for breastfeeding mothers.
