Study Notes
Definition and Incidence
- HELLP syndrome: a pregnancy complication characterized by Hemolysis (H), Elevated Liver enzymes (EL), and Low Platelets (LP)
- Incidence: 0.2-0.8% of pregnancies, 10-20% of severe preeclampsia cases
Causes and Risk Factors
- Preeclampsia: the primary underlying condition leading to HELLP syndrome
- Genetic predisposition: familial history of preeclampsia and HELLP syndrome
- Multiple pregnancy: increased risk due to excessive placental mass
- Advanced maternal age: increased risk with increasing age
- Pre-existing medical conditions: hypertension, diabetes, and kidney disease
Clinical Features
- Non-specific symptoms: nausea, vomiting, headache, and right upper quadrant pain
- Abdominal tenderness and guarding
- Elevated blood pressure and proteinuria (in preeclamptic cases)
- Laboratory findings:
- Hemolysis: schistocytes, high lactate dehydrogenase (LDH), and bilirubin
- Elevated liver enzymes: aspartate aminotransferase (AST) and alanine aminotransferase (ALT)
- Thrombocytopenia: low platelet count
Diagnosis
- Clinical suspicion: based on symptoms and laboratory results
- Laboratory tests:
- Complete Blood Count (CBC): platelet count, hemoglobin, and white blood cell count
- Liver Function Tests (LFTs): AST, ALT, and bilirubin
- Coagulation studies: prothrombin time (PT), partial thromboplastin time (PTT), and fibrinogen
- Urinalysis: proteinuria and hematuria
Management and Treatment
- Stabilization: maternal and fetal monitoring, fluid management, and pain control
- Delivery: expedited delivery, preferably via cesarean section, to prevent maternal and fetal complications
- Supportive care: platelet transfusions, antihypertensive medications, and corticosteroids (for fetal lung maturity)
- Intensive care unit (ICU) admission: for close monitoring and management of complications
Complications and Prognosis
- Maternal complications: acute kidney injury, pulmonary edema, and disseminated intravascular coagulation (DIC)
- Fetal complications: growth restriction, prematurity, and perinatal mortality
- Recurrence risk: 5-20% in subsequent pregnancies
- Prognosis: dependent on prompt diagnosis, management, and fetal outcome
Definition and Incidence
- HELLP syndrome is a pregnancy complication characterized by Hemolysis, Elevated Liver enzymes, and Low Platelets
- Occurs in 0.2-0.8% of pregnancies, and 10-20% of severe preeclampsia cases
Causes and Risk Factors
- Preeclampsia is the primary underlying condition leading to HELLP syndrome
- Familial history of preeclampsia and HELLP syndrome increases risk
- Multiple pregnancy increases risk due to excessive placental mass
- Advanced maternal age increases risk
- Pre-existing medical conditions like hypertension, diabetes, and kidney disease increase risk
Clinical Features
- Symptoms include nausea, vomiting, headache, and right upper quadrant pain
- Abdominal tenderness and guarding are present
- Elevated blood pressure and proteinuria are present in preeclamptic cases
- Laboratory findings include hemolysis, elevated liver enzymes, and thrombocytopenia
Diagnosis
- Based on clinical suspicion and laboratory results
- Laboratory tests include Complete Blood Count, Liver Function Tests, Coagulation studies, and Urinalysis
Management and Treatment
- Stabilization involves maternal and fetal monitoring, fluid management, and pain control
- Expedited delivery via cesarean section is preferred to prevent complications
- Supportive care includes platelet transfusions, antihypertensive medications, and corticosteroids
- Intensive care unit admission is necessary for close monitoring and management of complications
Complications and Prognosis
- Maternal complications include acute kidney injury, pulmonary edema, and disseminated intravascular coagulation
- Fetal complications include growth restriction, prematurity, and perinatal mortality
- Recurrence risk is 5-20% in subsequent pregnancies
- Prognosis depends on prompt diagnosis, management, and fetal outcome
