Objective:
This study aimed to evaluate maternal serum Netrin-1 and Netrin-4 levels in pregnancies complicated with placenta accreta spectrum.
Patients And Methods:
This cross-sectional study enrolled 49 pregnant women with the diagnosis of placenta accreta spectrum as the study group. Gestational age-matched 30 uncomplicated pregnant women with prior cesarean delivery and normal placentation were randomly selected as the control group. Maternal serum Netrin-1 and Netrin-4 levels were measured between weeks 34 and 36 of gestation.
Results:
There was no significant difference between the groups in terms of demographic characteristics. Maternal serum Netrin-1 levels were significantly lower in placenta accreta spectrum cases compared with those in the control group (p=0.038). There was no significant difference between the groups in terms of maternal serum Netrin-4 levels (p>0.05). There was a significant negative correlation between maternal serum Netrin-1 levels and the number of prior cesarean deliveries (r=-0.313, p=0.005).
Conclusions:
The observed decrease in maternal serum Netrin-1 levels in placenta accreta spectrum cases associated with increased angiogenesis might be one of the factors involved in the pathophysiology of this disease.
