Intrauterine growth restriction in pregnant women after kidney transplantation as a marker of preeclampsia
open access
Abstract
Objectives: Delayed motherhood is associated with an increasing number of comorbidities such as glomerulonephritis, systemic lupus erythematosus, and diabetic nephropathy. Women after renal transplant belong to the group of patients who require a highly individualized approach to treatment and diagnosis. The aim of the study was to validate the commonly used diagnostic criteria for preeclampsia which seem to be irrelevant in patients with chronic renal insufficiency.
Material and methods: The course of pregnancy and delivery were retrospectively analyzed in 48 renal transplant patients. Two patients were excluded. Group I included 23 patients with eutrophic neonates, while Group II consisted of 23 patients with fetal hypotrophy (birth weight of < 10th percentile).
Results: The duration of pregnancy was 34.5 and 35 weeks in Groups I and II, respectively. Mean birth weight in Groups I and II was 2608.64 g and 2046.30 g, respectively (p = 0.002). Mean weight percentile in Groups I and II was 36.57 and 2.91, respectively (p < 0.000). Proteinuria in the first half of pregnancy occurred in 16 and 14 patients from Groups I and II, respectively, and increased in the second half of pregnancy in 6 and 6 patients from Groups I and II, respectively. Patients from Group II were more prone to urinary tract infections (0.43 vs. 0.79; p = 0.02).
Conclusions: Current diagnostic criteria for preeclampsia are insufficient in case of pregnant women after kidney transplant. General criteria should be applied with special care in women with chronic kidney disease or in patients with systemic lupus erythematosus. As a predictive factor of neonatal morbidity, intrauterine growth restriction seems to be more valuable than typical markers of kidney function.
