Objective:

To report the case of pregnant woman with Guillain-Barré syndrome (GBS) presenting as the Miller Fisher variant, and to review the literature on the diagnosis, treatment and prognosis of this GBS variant during gestation.

Materials and Methods:

Pregnant woman presenting at 27 weeks of gestation with Miller Fisher syndrome (MFS), treated in a military referral hospital with a satisfactory course after 15 days, continuation of normal pregnancy and delivery of a healthy neonate at 38 weeks. A search of the literature was conducted in the Medline via PubMed, Lilacs, SciELO, ScienceDirect and Ovid databases using the terms “Pregnancy,” “Miller Fisher syndrome,” “Guillain-Barré syndrome”. Cohorts, case series and case reports of pregnant women with MFS were included. Data on diagnostic methods, treatment and maternal and perinatal prognosis were extracted. The search was made on June 2020, with no restriction by date, but restriction by language (Spanish and English).

Results:

Overall, 423 titles were identified, three studies met the inclusion criteria, the three of them corresponding to case reports. All cases were found to be seropositive for anti-GQ1b ganglioside antibodies. No imaging abnormalities were found in any of the cases. Two patients received IV immunoglobulin and the third patient was kept under observation. No obstetric complications have be documented so far.

Conclusion:

There are few cases of MFS reported during pregnancy. Intravenous immunoglobulin is the most frequently used treatment option. Plasmapheresis was used in the case presented here. The impact of the Miller Fisher variant on the normal course of gestation and on long-term perinatal outcomes is unknown. Further studies that look into the diagnosis, treatment and prognosis of this condition are required.
