Abstract

Abstract Aim: The aim of this study is to compare NLR and PLR ratios between pregnant women diagnosed with intrauterine fetal death after 20 weeks and a healthy control group of pregnant women. Materials and Methods: This was a retrospective, single-center study that included 180 patients, comprising 90 pregnant women diagnosed with intrauterine death after 20 weeks and an equal number of healthy controls. NLR (NLR = neutrophil/lymphocyte) and PLR (PLR = platelet/lymphocyte) were calculated. Data distribution was compared using the Mann–Whitney U test when not normally distributed. ROC analysis was used to calculate cutoff points for NLR and PLR predicting IUEX. Results: Both NLR and PLR were significantly lower in the IUEX group compared with controls (NLR: p=0.020; PLR: p<0.001). ROC analysis identified PLR cutoff of 47.31 with 100% sensitivity and 100% specificity (AUC=0.983; p<0.001). For NLR, the best cutoff was 3.95 with 63% sensitivity and 32% specificity (AUC=0.603; p=0.019). Conclusion: Our findings suggest that PLR may serve as a stronger biomarker for predicting intrauterine death after 20 weeks compared with NLR, though prospective multicenter validation is required to standardize thresholds and assess clinical utility.

Özet

Giriş: Bu çalışmanın amacı, 20 haftadan sonra intrauterin fetal ölüm tanısı konulan hamile kadınlar ile sağlıklı kontrol grubu hamile kadınlar arasında NLR ve PLR oranlarını karşılaştırmaktır. Materyal ve Yöntemler: Retrospektif, tek merkezli bir çalışma olup, 20 haftadan sonra intrauterin ölüm tanısı konulan 90 gebe ile eşit sayıda sağlıklı kontrol içeren 180 hasta dahil edildi. NLR (NLR = nötrofil/lenfosit) ve PLR (PLR = trombosit/lenfosit) hesaplandı. Verilerin dağılımı normal olmama durumunda Mann–Whitney U testi ile karşılaştırıldı. ROC analizi ile NLR ve PLR için IUEX öngörüsü belirleyen kesim noktaları hesaplandı. Sonuçlar: NLR ve PLR, kontrol grubuna kıyasla IUEX grubunda anlamlı olarak daha düşüktü (NLR: p=0,020; PLR: p<0,001). ROC analizi, %100 duyarlılık ve %100 özgüllük ile 47,31 PLR kesme değerini belirledi (AUC=0,983; p<0,001). NLR için en iyi kesme değeri %63 duyarlılık ve %32 özgüllük ile 3,95 idi (AUC=0,603; p=0,019). Sonuç: Bulgularımız, PLR'nin NLR'ye kıyasla 20 haftadan sonra intrauterin ölümü öngörmede daha güçlü bir biyomarker olabileceğini göstermektedir, ancak eşik değerleri standartlaştırmak ve klinik yararını değerlendirmek için prospektif çok merkezli bir doğrulama gereklidir.
