Available accessReview articleFirst published June, 2015pp. 61-67An increasing number of women with rare inherited disorders of metabolism are becoming pregnant. Whilst, in general, outcomes for women and their children are good, there are issues that need to be considered. Due to the rarity of many conditions, there is limited specific guidance available on best management. Prepregnancy counselling with information on inheritance, options for reproduction, teratogenicity risk, potential impact on maternal health and long-term health of children should be offered. With appropriate specialist management, the teratogenic risk of conditions such as maternal phenylketonuria (PKU) can be eliminated, and the risk of metabolic decompensation in other disorders of intoxication or energy metabolism significantly reduced. Newer therapies, such as enzyme replacement therapy, appear to be safe in pregnancy, but specific advice should be sought. Multidisciplinary management, and close liaison between obstetricians and other specialists is required for women in whom there is cardiac, renal, respiratory, joint or other organ involvement.
Available accessResearch articleFirst published June, 2015pp. 68-85Gestational diabetes mellitus can be defined as ‘glucose intolerance or hyperglycaemia with onset or first recognition during pregnancy.’
The objective of our systematic review was to see if there was any intervention that could be used for primary prevention of gestational diabetes mellitus in women with risk factors for gestational diabetes mellitus.
Major databases were searched from 1966 to Aug 2012 without language restriction.
Randomised trials comparing intervention with standard care in women with risk factors for gestational diabetes were included. Meta-analysis was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. The primary outcome assessed was the incidence of gestational diabetes.
Data from included trials were extracted independently by two authors and analysed using Rev-Man 5.
A total of 2422 women from 14 randomised trials were included; which compared diet (four randomised trials), exercise (three randomised trials), lifestyle changes (five randomised trials) and metformin (two randomised trials) with standard care in women with risk factors for gestational diabetes mellitus. Dietary intervention was associated with a statistically significantly lower incidence of gestational diabetes (Odds ratio 0.33, 95% CI 0.14 to 0.76) and gestational hypertension (Odds ratio 0.28, 95% CI 0.09, 0.86) compared to standard care. There was no statistically significant difference in the incidence of gestational diabetes mellitus or in the secondary outcomes with exercise, lifestyle changes or metformin use compared to standard care.
The use of dietary intervention has shown a statistically significantly lower incidence of gestational diabetes mellitus and gestational hypertension compared to standard care in women with risk factors for gestational diabetes mellitus.

We undertook a retrospective cohort study at a tertiary institution to examine the impact of renal disease on pregnancy outcomes and the effect of pregnancy on disease progression.
A total of 55 pregnancies of patients with renal disease admitted from 2003 to 2010 to the Royal Brisbane and Women’s Hospital were analysed. Pre-conception variables, fetal/delivery and maternal outcomes were analysed in this group and in a control group of women with normal kidney function pre-pregnancy.
Of the 55 pregnancies, 71% experienced pre-term delivery, 38% had intra-uterine growth restriction and 62% required caesarean section. Of all, 60% of neonates required neonatal intensive care unit (NICU) admission and six perinatal deaths occurred. Of all, 67% of women suffered preeclampsia, 47% anaemia and 3 patients required dialysis in pregnancy. Postpartum deterioration of renal function occurred in patients with pre-conception chronic kidney disease stage 3–5.
Chronic kidney disease of all stages is a risk factor for adverse pregnancy outcomes. In a tertiary institution however, there is a high rate of successful pregnancy (84%).
Available accessResearch articleFirst published June, 2015pp. 99-101Cystic fibrosis manifests as a multisystem disease, despite this female fertility is relatively preserved with levels approaching that of the non-cystic fibrosis population. We reviewed pregnancies in cystic fibrosis patients over a 10-year period from a UK adult cystic fibrosis centre by considering maternal and fetal outcomes.
We conducted a retrospective case-note review of pregnancies during 2003–2013 using respiratory and obstetric records.
We observed moderate falls in lung function immediately after delivery, which persisted at 12 months postpartum. We found that a decline in lung function at delivery was a marker for further decline in function during the subsequent postpartum period. We found baseline lung function was predictive of gestational age at delivery. We observed a high incidence of haemoptysis.
Consistent with current guidance we found pregnancy is feasible and well tolerated in the majority of patients with cystic fibrosis. There was a high incidence of haemoptysis, which warrants further study.
Available accessCase reportFirst published June, 2015pp. 102-104Infective endocarditis in pregnancy is associated with high maternal and fetal morbidity and mortality and is estimated to complicate approximately 1 in 100,000 pregnancies. We report the case of a 33-year-old patient who presented at 30 weeks and 3 days gestation in her third pregnancy. The patient described a 3 week history of feeling generally unwell, an episode of temporary speech disturbance, right shoulder tip pain, left subscapular pain on inspiration and chest discomfort. Investigations included an echocardiogram, which revealed a large mobile mass on the aortic coronary cusp and a small mass on the non-coronary cusp. There was significant aortic regurgitation. Blood cultures were positive for staphylococcus lugdunensis. A diagnosis of infective endocarditis was made. The patient deteriorated, with worsening cardiac function, and proceeded to have a caesarean section on day 7 of admission. Her baby had multiple limb abnormalities, subsequently diagnosed as arthrogryposis multiplex congenita. Aortic valve replacement with a mechanical valve was then performed on day 3 post partum. The patient recovered well post operatively and was discharged home with her baby on day 45 post partum. The commonest complications of IE are congestive cardiac failure, perivalvular extension and systemic embolization. The management of infective endocarditis in pregnancy is similar to that of the non-pregnant however there is high foetal mortality associated with cardiopulmonary by-pass for cardiac surgery. The patient described here developed staphylococcus lugdunensis infective endocarditis, which is a rare but aggressive causative organism in infective endocarditis. Infective endocarditis in pregnancy is a rare but serious condition with significant fetal and maternal morbidity and mortality. Early diagnosis with a multidisciplinary team approach is essential to improve outcomes.
