Insights
Severe preeclampsia with hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome in early pregnancy poses risks. Eculizumab treatment improved maternal health and prolonged pregnancy, potentially reducing neonatal complications.
Area of Science:
- Obstetrics and Gynecology
- Immunology
- Neonatal Medicine
Background:
- Severe preeclampsia with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome presents a critical management dilemma at extremely premature gestations.
- The dilemma involves balancing the need for delivery for maternal well-being against prolonging pregnancy to mitigate prematurity-related morbidities.
Observation:
- A case of severe preeclampsia/HELLP syndrome at 26 weeks gestation is presented.
- The patient was treated with Eculizumab, a C5 complement protein inhibitor.
Findings:
- Eculizumab treatment led to significant clinical improvement and normalization of laboratory parameters.
- Pregnancy was successfully prolonged by 17 days following Eculizumab administration.
Implications:
- This case suggests complement inhibition with Eculizumab may be a viable therapeutic strategy for severe preeclampsia/HELLP syndrome.
- Prolonging pregnancy in such cases may reduce neonatal morbidity and associated long-term healthcare costs.
- Further research into complement inhibition for managing severe preeclampsia/HELLP syndrome is warranted.
Abstract:
Severe preeclampsia with hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a leading cause of maternal and neonatal morbidity and mortality worldwide. Occurrence at an extremely premature gestational age is most challenging as there are dichotomous imperatives: delivery as definitive therapy for maternal health vs. prolongation of pregnancy to avoid prematurity and associated morbidities. We describe a patient presenting with severe preeclampsia/HELLP syndrome at 26 weeks gestation that was treated with Eculizumab, a targeted inhibitor of complement protein C5, which resulted in marked clinical improvement and complete normalization of lab parameters. Pregnancy was prolonged 17 days, likely resulting in a reduction of neonatal morbidity with its associated short and long-term health care costs. Successful use of Eculizumab in this case suggests that complement inhibition may be an effective treatment strategy for severe preeclampsia/HELLP syndrome.
