What is the management plan for a pregnant patient with significant proteinuria, mild anemia, and elevated uric acid levels?

Management of Severe Preeclampsia with Nephrotic-Range Proteinuria

This patient requires immediate delivery planning given the massive proteinuria (P/C ratio 10.5 g/g, equivalent to >10 g/24h), which far exceeds nephrotic range and is strongly associated with severe maternal and neonatal complications. 1

Immediate Clinical Assessment

Confirm Preeclampsia Diagnosis and Severity

• Blood pressure measurement is critical but not provided - measure immediately and confirm if ≥140/90 mmHg (or ≥160/110 mmHg for severe hypertension) 1
• Gestational age determination is essential - if ≥37 weeks, proceed directly to delivery; if <37 weeks, assess for severe features requiring expedited delivery 2
• The urine P/C ratio of 10.5 g/g represents massive proteinuria (>5 g/24h), which is independently associated with worse maternal outcomes and earlier delivery 1

Assess for Severe Features Requiring Urgent Intervention

• Platelets 161 K/μL - borderline low but not yet indicating HELLP syndrome (threshold <100 K/μL) 2
• AST 36 U/L - normal, no hepatocellular injury currently 1
• Serum creatinine 0.7 mg/dL - normal renal function despite massive proteinuria 1
• Uric acid 9 mg/dL - significantly elevated; combined with massive proteinuria (P/C >4.9), this creates a striking association with eclamptic crisis risk 3, 4
• Hemoglobin 10.1 g/dL - mild anemia, monitor for hemolysis 1
• Evaluate immediately for: severe headache, visual disturbances, right upper quadrant pain, or hyperreflexia 1

Immediate Management Steps

Blood Pressure Control

• If BP ≥140/90 mmHg: initiate oral methyldopa, labetalol, or nifedipine targeting diastolic 85 mmHg and systolic 110-140 mmHg 2
• If BP ≥160/110 mmHg: urgent treatment with oral nifedipine or IV labetalol/hydralazine in monitored setting, confirm within 15 minutes 1, 2

Seizure Prophylaxis Decision

• Strongly consider magnesium sulfate given the combination of uric acid >5.9 mg/dL and P/C ratio >4.9, which dramatically increases eclampsia risk 2, 4
• Administer if any neurological symptoms, severe hypertension, or other severe features present 2

Thromboprophylaxis Consideration

• Confirm nephrotic syndrome with 24-hour urine collection - the P/C ratio of 10.5 suggests >10 g/24h proteinuria, which has specific implications for thromboprophylaxis 1, 5
• Consider prophylactic anticoagulation given nephrotic-range proteinuria 1

Delivery Planning

Timing of Delivery

• If ≥37 weeks: deliver now after maternal stabilization 2
• If <37 weeks with severe features: deliver within 24-48 hours after maternal stabilization 2
• Do not delay delivery based on proteinuria quantification alone - the massive proteinuria itself indicates high-risk disease 1, 2

Mode of Delivery

• Vaginal delivery preferred unless standard obstetric indications for cesarean exist 2
• Initiate induction after maternal stabilization 2

Fetal Assessment

• Perform biophysical profile and continuous electronic fetal monitoring 2
• Do not delay delivery for non-reactive testing alone 2

Monitoring for Deterioration

Laboratory Surveillance

• Repeat CBC immediately - watch for progressive thrombocytopenia (<100 K/μL indicates HELLP) 2
• Comprehensive metabolic panel - monitor for rising creatinine or transaminases 2
• Expedite delivery immediately if: platelets drop below 100 K/μL, transaminases rise significantly, or severe hypertension develops 2

Critical Pitfalls to Avoid

• Do not assume this is benign gestational hypertension - the combination of massive proteinuria and elevated uric acid indicates high-risk preeclampsia with significant eclampsia risk 3, 4
• Do not wait for symptoms to develop - massive proteinuria (>5 g/24h) is associated with worse neonatal outcomes independent of other features 1
• Do not continue pregnancy beyond term - delivery at 37 weeks is recommended for preeclampsia without severe features, and earlier if severe features present 2
• Do not overlook the uric acid level - at 9 mg/dL combined with P/C >4.9, this patient has markedly increased eclampsia risk requiring heightened vigilance 3, 4

Postpartum Management

• Close monitoring for 48-72 hours postpartum - 20% of HELLP cases occur within 48 hours of delivery 2
• Reassess proteinuria at 3 months postpartum - if persistent, this indicates underlying primary renal disease requiring nephrology referral 6, 5
• Continue antihypertensive therapy as needed with pregnancy-safe agents if breastfeeding 5
