Lupus nephritis in pregnancy requires differentiation from preeclampsia and HELLP because they all have which features?

• A. Proteinuria, hypertension, and elevated urea
• B. Hypotension and hypoglycemia
• C. Hyperlipidemia and edema only
• D. Thrombocytopenia only

Answer: (A)

The key idea is that lupus nephritis, preeclampsia, and HELLP can all involve the kidneys and raise blood pressure during pregnancy. The best answer reflects the common features these conditions share: protein in the urine, high blood pressure, and signs of reduced kidney function (elevated urea/creatinine). Proteinuria shows glomerular injury, hypertension arises from endothelial dysfunction and vasospasm or volume changes, and elevated urea indicates impaired renal clearance. While HELLP adds hemolysis and low platelets and preeclampsia can present with additional systemic features, the overlapping trio of proteinuria, hypertension, and elevated urea is what ties them together. The other options describe findings that aren’t present in all three conditions.
