What is the cause of post-delivery complications characterized by elevated liver enzymes, acute kidney injury, hypoalbuminemia, thrombocytopenia, and severe anemia?

Post-Delivery HELLP Syndrome with Multi-Organ Involvement

This clinical presentation is diagnostic of HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) with severe multi-organ complications including acute kidney injury and acute liver failure. 1, 2

Diagnostic Confirmation

The constellation of findings confirms active HELLP syndrome:

• Elevated liver enzymes (GGT, LDH, ALP) indicate hepatocellular injury and cholestasis characteristic of HELLP 3
• Platelet count of 100,000/mm³ meets the diagnostic threshold for severe thrombocytopenia in HELLP syndrome, indicating active disease and significant maternal risk 2, 4
• Hemoglobin 7.1 g/dL reflects microangiopathic hemolytic anemia, a core component of the HELLP triad 3, 5
• Acute kidney injury occurs in 25% of severe HELLP cases and indicates disease severity 6, 7
• Hypoalbuminemia results from hepatic synthetic dysfunction and capillary leak 3, 8

The American College of Obstetricians and Gynecologists confirms that this triad with these laboratory values represents complete HELLP syndrome requiring urgent intervention 1, 2.

Critical Immediate Actions Required

Life-Threatening Complications to Rule Out

Perform urgent abdominal ultrasound immediately to exclude subcapsular liver hematoma or hepatic rupture, which are life-threatening complications more likely with severe thrombocytopenia and persistent epigastric pain 1, 2. Hepatic complications require surgical intervention and represent a major cause of maternal mortality 1, 5.

ICU-Level Monitoring

• Transfer to ICU or high-dependency unit for continuous monitoring of blood pressure, central venous pressure, urinary output, ECG, and oxygen saturation 2, 4
• Insert urinary catheter for hourly output monitoring; oliguria <400 mL/24h indicates severe disease 4
• Consider central venous catheter as these patients are often relatively hypovolemic despite appearing edematous 3, 4

Laboratory Surveillance

Monitor CBC with platelets, comprehensive metabolic panel, LDH, peripheral smear, and coagulation studies every 6-12 hours for at least 24-48 hours postpartum, as 30% of HELLP cases occur or worsen after delivery 1, 4.

Specific Management Interventions

Blood Product Support

• Platelet transfusion is mandatory given platelet count of 100,000/mm³ in the postoperative period, as this level indicates severe thrombocytopenia with increased risk of abnormal coagulation and bleeding complications 2, 4
• Transfuse packed red blood cells to correct severe anemia (Hb 7.1 g/dL) 6, 8
• Administer fresh frozen plasma if coagulopathy is present (check INR, PTT, fibrinogen) 3, 6

Seizure Prophylaxis

Initiate magnesium sulfate immediately for seizure prevention in all women with HELLP syndrome and severe hypertension, following American College of Obstetricians and Gynecologists dosing protocols 2, 4.

Hypertension Management

Escalate antihypertensive therapy if blood pressure remains elevated, using labetalol, nifedipine, or hydralazine for severe hypertension 2. For severe hypertension, hydralazine dosing is 5 mg IV bolus, then 10 mg every 20-30 minutes to maximum 25 mg 2.

Renal Support

Prepare for possible renal replacement therapy given the acute kidney injury. Renal histopathology in persistent AKI from HELLP shows acute tubular necrosis (most common), thrombotic microangiopathy, or acute renal cortical necrosis 7. Patients with acute renal cortical necrosis or thrombotic microangiopathy with acute tubular necrosis may develop chronic renal dysfunction 7.

Disease Trajectory and Prognosis

Liver function and platelet counts typically normalize within days to weeks after delivery 2. However, the degree of thrombocytopenia correlates directly with severity of liver dysfunction and predicts adverse maternal outcomes 4, 6.

Poor Prognostic Indicators Present

This patient has multiple markers associated with high mortality risk in HELLP syndrome requiring intensive care 6:

• Low platelet count (100,000/mm³)
• Elevated AST, ALT, LDH
• Acute kidney injury
• Severe anemia

Maternal mortality rate for HELLP syndrome requiring ICU admission is 14%, with disseminated intravascular coagulation (29%), acute renal failure (25%), and postpartum hemorrhage (21%) being the most common complications 6.

Critical Pitfalls to Avoid

• Do not delay intervention waiting for laboratory values to normalize - HELLP syndrome only resolves after delivery, and maternal mortality is 3.4% with delayed intervention 4
• Do not use regional anesthesia if repeat procedures are needed with platelets <100,000/mm³ due to risk of epidural hematoma 4
• Do not administer corticosteroids to improve maternal HELLP outcomes - they are ineffective for maternal disease (only indicated for fetal lung maturity if delivery anticipated before 35 weeks) 2, 4

Differential Considerations

While HELLP syndrome is the primary diagnosis, consider overlapping conditions:

• Acute fatty liver of pregnancy (AFLP) can present similarly but typically shows hypoglycemia, elevated ammonia, prolonged PT, and DIC in >75% of cases 3
• Thrombotic thrombocytopenic purpura (TTP) may occur secondary to HELLP-induced acute liver failure with severely diminished ADAMTS13 activity (<5%), potentially requiring therapeutic plasma exchange 9
