Long-term renal function after HELLP syndrome.

Area of Science:

• Obstetrics and Gynecology
• Nephrology
• Cardiology

Background:

• HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) is a severe pregnancy complication.
• Potential long-term effects of HELLP syndrome on maternal renal function remain a concern.
• The necessity of continued renal follow-up post-HELLP syndrome requires clarification.

Purpose of the Study:

• To evaluate long-term renal function (≥5 years) in women with a history of HELLP syndrome.
• To compare renal function markers between women with and without prior HELLP syndrome.
• To determine if long-term renal follow-up is indicated after HELLP syndrome.

Main Methods:

• Prospective cohort study comparing women with and without HELLP syndrome.
• Assessment of renal function via serum creatinine, urinary creatinine, creatinine clearance, and protein/albumin-to-creatinine ratios.
• Long-term follow-up of at least 5 years post-delivery.
• Comparison of blood pressure measurements between groups.

Main Results:

• No significant differences were observed in body mass index, serum/urinary creatinine, creatinine clearance, or urinary protein/albumin-to-creatinine ratios between groups.
• Women with a history of HELLP syndrome exhibited significantly higher diastolic and systolic blood pressures.
• These blood pressure differences persisted even 5 years after the HELLP syndrome event.

Conclusions:

• Long-term renal function appears preserved in women who have experienced HELLP syndrome.
• Continued renal follow-up is likely unnecessary for women with a history of HELLP syndrome.
• Women with prior HELLP syndrome require monitoring for sustained hypertension, suggesting a cardiovascular risk.
