HELLP syndrome stands for Hemolysis with a microangiopathic blood smear, Elevated Liver enzymes, and Low Platelet count. It is common in pregnant and postpartum patients as complications.
0.5% to 0.9% of women have HELLP syndrome. 70% of instances occur in the third trimester and 30% within 48 hours following delivery. HELLP syndrome causes 0 to 24% maternal mortality and up to 37% perinatal mortality.
Although its cause has yet to be pinpointed, HELLP syndrome is believed to be a complement-mediated (enhanced activity of our immune cells to destroy pathogens) inflammatory illness that manifests itself systemically. It is thought that there may be a similar pathogenesis between HELLP syndrome and preeclampsia with poor placentation. However, for unknown reasons, this can cause the complement system to be activated too much and cause more inflammation in the liver in people with HELLP syndrome. A subtype of HELLP syndrome is characterized by complement dysregulation linked with thrombotic microangiopathy and can manifest with pregnancy-related hemolytic uremic syndrome (HUS).
Women may have signs of HELLP syndrome during pregnancy or soon after giving birth. Some of them are the following:
In rare cases, women may also experience:
The following laboratory tests are required to establish the diagnosis of HELLP syndrome in a pregnant patient in the third trimester of pregnancy or immediate postpartum 7 days after birth who presents with the above symptoms, including new-onset hypertension or proteinuria:
Drugs that reduce blood pressure and prevent seizures may be part of the treatment plan for HELLP syndrome. A transfusion is necessary for some pregnant women. Donated whole blood or blood plasma is used in this therapy.
HELLP syndrome is ultimately treated through delivery. Preterm delivery is a possible outcome if you have HELLP syndrome. The doctor may prescribe corticosteroids to aid with your infant's lung maturation.
Your doctor may prescribe medication to help bring on labor. Another option is having a cesarean section to accomplish the birth (C-section).
Preventing HELLP syndrome is currently impossible. Ensure that you are receiving routine prenatal care. If you are at a high risk for HELLP syndrome, your doctor may recommend that you begin taking low-dose aspirin after the first trimester.
