A recent case study published in NeoReviews described a female patient who had a prior pregnancy possibly complicated by gestational alloimmune liver disease (GALD) became pregnant again, prompting close medical monitoring during pregnancy and after delivery.

Like fetal and neonatal alloimmune thrombocytopenia (FNAITFetal and neonatal alloimmune thrombocytopenia A rare condition in which a mother’s immune system attacks fetal platelets, leading to dangerously low platelet levels before and/or after birth.), GALD is an alloimmune condition. This case report was published in Maternal-Fetal Case Studies.
A 33-year-old pregnant patient had a previous pregnancy that ended in fetal death. This was identified at 20 weeks of gestation. Following a fetal autopsy, doctors discovered that there was hemosoderin deposition in the fetal liver and pancreas, findings that were suggestive of GALD.
Because GALD has a very high recurrence rate (90% to 95%), the patient’s current pregnancy was closely monitored. As a precautionary measure, the patient was administered intravenous immunoglobulinIntravenous immunoglobulin A treatment given to pregnant women with a history of FNAIT or known alloantibodies. IVIG reduces the immune reaction against fetal platelets. (IVIGIntravenous immunoglobulin A treatment given to pregnant women with a history of FNAIT or known alloantibodies.

These showed a consistent growth of the fetus, with a normal-looking liver.
From 32 weeks of gestation onwards, the patient underwent detailed weekly monitoring. At 38 weeks of gestation, induction of labor resulted in a successful vaginal delivery. The patient had postpartum hemorrhageFetal hemorrhage Any bleeding that occurs before birth. In FNAIT, this usually results from extremely low platelet counts. but recovered well.

Laboratory tests were not indicative of the presence of GALD. Nevertheless, the child received nirsevimab therapy prior to discharge. After discharge, the child was followed up with the gastroenterology medical team as an added precautionary measure.
GALD is a rare fetal condition that can result in fetal/newborn death. Unfortunately, it is rarely diagnosed during pregnancy because findings tend to be non-specific. In the event that a pregnancy is suspected to be affected by GALD, subsequent pregnancies are always closely monitored, given the high disease recurrence rate and the availability of effective preventative therapies.
“For pregnant patients at risk of recurrent GALD, treatment with weekly antenatal IVIG leads to a high likelihood of successful outcomes, as described in this case,” the authors of the report wrote.
