Management of Parkinson's Disease During Pregnancy: Literature Review and Multidisciplinary Input

Background

There are no standardized clinical guidelines for the management of Parkinson's disease (PD) during pregnancy. Increasing maternal age would suggest that the incidence of pregnancy in women diagnosed with PD is likely to increase.

Objective

To evaluate the evidence for the treatment of PD during pregnancy and to canvass opinion from patients and clinical teams as to the optimum clinical management in this setting.

Methods

This involved (1) a literature review of available evidence for the use of oral medical therapy for the management of PD during pregnancy and (2) an anonymized survey of patients and clinical teams relating to previous clinical experiences.

Results

A literature review identified 31 publications (148 pregnancies, 49 PD, 2 parkinsonism, 21 dopa-responsive dystonia, 32 restless leg syndrome, 1 schizophrenia, and 43 unknown indication) detailing treatment with levodopa, and 12 publications with dopamine agonists. Adverse outcomes included seizures and congenital malformations. Survey participation included patients (n = 7), neurologists (n = 35), PD nurse specialists (n = 50), obstetricians (n = 15), and midwives (n = 20) and identified a further 34 cases of pregnancy in women with PD. Common themes for suggested management included optimization of motor symptoms, preference for levodopa monotherapy, and normal delivery unless indicated by obstetric causes.

Conclusions

This study demonstrates the paucity of evidence for decision-making in the medical management of PD during pregnancy. Collaboration is needed to develop a prospective registry, with longitudinal maternal and child health outcome measures to facilitate consensus management guidelines.

Parkinson's disease and pregnancy: An updated review

Pregnancy does not often occur in the setting of Parkinson's disease (PD) as the most common age of onset is beyond the childbearing years, yet management of these two conditions is crucial for the health of both mother and child. Here we review treatment data of PD during pregnancy, primarily from case reports and drug registries, and focus on available evidence regarding the pregnancy risks for patient and fetus. Historically, it was reported that many women had worsening of symptoms during pregnancy but this may be because anti-parkinsonian medications were not recommended or were under dosed. Levodopa has the best safety data for use in pregnancy and amantadine should be avoided in women who are pregnant or trying to become pregnant. The data for other pharmacological and surgical treatments is less clear. There is no evidence that women with PD have higher rates of birth or fetal complications.

Pregnancy outcome following use of levodopa, pramipexole, ropinirole, and rotigotine for restless legs syndrome during pregnancy: a case series

BACKGROUND

Restless legs syndrome (RLS) is related to parity, and its symptoms may worsen during pregnancy. Treatment with levodopa or dopamine agonists is the first-line therapy for RLS; however, there are limited data on treatment in pregnancy. We therefore assessed the safety of levodopa, pramipexole, rotigotine, and ropinirole in pregnancy.

METHODS

Prospective documentation of pregnancies exposed to levodopa, pramipexole, rotigotine, and ropinirole between 1998 and 2011 was evaluated as to their outcome (teratogenicity or fetotoxicity) by the Berlin Institute for Clinical Teratology and Drug Risk Assessment in Pregnancy.

RESULTS

We were able to complete 59 pregnancy outcomes exposed to RLS pharmacotherapy. For specific treatments, the numbers of exposed pregnancies/live born children/spontaneous abortions/induced abortions/malformations were as follows: levodopa only: 38/29 (one pair of twins)/3/7/3; pramipexole only: 12/9/3/0/0; rotigotine only: 2/2/0/0/0; ropinirole only: 3/2/0/1/0; levodopa combined with pramipexole: 3/3/0/0/0; levodopa combined with ropinirole: 1/1/0/0/0. No major birth defects were found with any RLS treatment, and three infants exposed to levodopa had minor anomalies.

CONCLUSIONS

In our small prospective case series, there was no increased risk above baseline for major malformations or other adverse outcomes for levodopa and pramipexole. If necessary, levodopa treatment may be considered as an alternative to cabergoline, for which safety has been well documented in pregnancy.

Successful birth of an IVF baby in a patient with Parkinson's disease

Parkinson's disease, although rare in young patients, may be encountered in the reproductive age group. We report a rare combination of this disease with infertility, which has not been previously reported. The case record of a 29-year-old woman with infertility and Parkinson's disease are retrospectively reviewed. An IVF indicated for tubal factor infertility resulted in a successful singleton pregnancy. She delivered a healthy male baby without experiencing any worsening of her Parkinsonism. The course of pregnancy remained unaffected by the Parkinson's disease and anti-Parkinsonian drugs. The details of the infertility management, antenatal and postnatal course, and medications are described. With careful evaluation, counseling, and monitoring, IVF may be safely used in women with Parkinson's disease.
