Soluble Factors and Renal Outcome in Preeclampsia

This is prospective observational study.Study subjects are pregnant women aged more than 18 years more than 24 weeks of gestation who were diagnosed and classified as preeclampsia or gestational hypertension by the criteria recommends by the American College of Obstetricians and Gynecologists (ACOG).14

Severe preeclampsia will be diagnosed by:

• A systolic/diastolic blood pressure ≥ 140 mmHg occurring on two occasions at least 4 hours apart after 20 weeks of gestation a women whose blood pressure has previously been normal
• Proteinuria with excretion of 0.3 gm or more of protein in a 24 hour urine specimen or urine dipstick results of at least 1+(30 mg per deciliter) on two occasions The exclusion criteria were chronic hypertension before pregnancy ,chronic kidney disease according to KDIGO criteria15 ,twin pregnancies,underlying diabetes mellitus .Of the 42 women enrolled in this trial,we excluded 2 patients who had twin pregnancies and history of diabetes mellitus. Eight women were lost to follow up. The remaining 32 patients completed the study.

Data collection and Laboratory Measurements Baseline demographic and clinical data will be recorded as follows: age, gestational age, blood pressure, medication history, parity. Laboratory data included complete blood count, blood urea nitrogen (BUN), creatinine, aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, alkaline phosphate, lactate dehydrogenase (LDH), 24 -hour urine protein excretion and random urine protein-creatinine ratio. Enzyme-linked immunosorbent assay (ELISAs) for human soluble endoglin, SFlt1, and free PIGF will be conducted in duplicate with the use of commercial kits (R§D Systems).

The ratio of SFlt1:PIGF will be calculated. All the participants will be followed up at 3 months and 1 year in which blood pressure, UACR and serum creatinine will be recorded at each visit.
