Abstract

Objective: Abnormal changes in immune-mediated inflammation contribute to the pathogenesis of preeclampsia (PE). In our study, we aimed to investigate systemic inflammatory indexes [neutrophil/lymphocyte rate (NLR), platelet/lymphocyte rate (PLR), monocyte/ lymphocyte rate (MLR), platelet/neutrophil rate (PNR)] as disease markers as well as a theoretical basis for early diagnosis opportunity, evaluation of disease severity and prognosis of PE. Methods: The records of 573 pregnant women were evaluated in this retrospective case-controlled study. Twenty-eight patients were excluded from the study as they suffered eclamptic seizure while 50 patients were excluded from the study due to HELLP syndrome (hemolysis, thrombocytopenia and elevated liver transaminases), 20 patients due to superimposed preeclampsia, 19 patients due to chronic hypertension and 25 patients due to gestational hypertension. Three groups were established where 190 patients were included in PE group, 119 patients in severe PE group and 122 healthy singleton pregnant women in the control group. Platelet numbers, neutrophil, monocyte and lymphocyte values as well as NLR, PLR, MLR and PNR values which are systemic inflammatory response markers of all groups were recorded and compared with each other. Results: While no significant difference was found between PE and severe PE group, there was statistically significant difference in terms of the numbers of platelet, neutrophil, monocyte and lymphocyte numbers and NLR, PLR, MLR and PNR values when both PE groups were compared to the control group. When NLR is considered >3.497 for the control and PE groups, sensitivity is 51.5%, specificity is 50.8%, positive predictive value is 71.9%, and negative predictive value is 71.4%. Conclusion: Secondary analyses of complete blood count parameters evaluate systemic inflammation and immunity effectively. According to the absolute leukocyte counts, NLR and PLR provide more effective markers in terms of clinical evaluation, and evaluation of PE severity and PE prognosis. However, with current findings, systemic inflammatory indexes are insufficient to establish preeclampsia diagnosis and to predict its severity.

Özet

Amaç: İmmün aracılı inşamasyondaki anormal değişiklikler preeklampsinin (PE) patogenezine katkıda bulunur. Bu çalışmada amacımız sistemik inşamatuar indekslerini [nötrofil/lenfosit oranı (NLO), trombosit/lenfosit oranı (TLO), monosit/lenfosit oranı (MLO), trombosit /nötrofil oranı (TNO)] hastalık göstergeleri olarak ve aynı zamanda erken tanı imkânı, hastalığın şiddetinin de- ğerlendirilmesi ve PE’nin prognozu için teorik bir temel olarak araştırmaktır. Yöntem: Retrospektif olgu kontrollü olarak planlanan bu çalışmada 573 gebenin klinik kayıtları tarandı. Yirmi sekiz hasta eklamptik nöbet geçirmesi, 50 hasta HELLP sendromu (hemoliz, trombositopeni ve yüksek karaciğer transaminaz), 20 hasta süperempoze preeklampsi, 19 hasta kronik hipertansiyon, 25 hasta gestasyonel hipertansiyonu olması nedeniyle çalışma dışına alındı. Yüz doksan hasta PE, 119 hasta şiddetli PE ve 122 sağlıklı tekil gebe kontrol grubuna alınarak 3 grup oluşturuldu. Tüm grupların hemoglobin, trombosit sayısı, nötrofil, monosit, lenfosit değerleri ile birlikte sistemik inşamatuar yanıt belirteçleri olan NLO, TLO, MLO, TNO oranları kayıt altına alındı ve birbirleriyle karşılaştı- rıldı. Bulgular: PE ve şiddetli PE grupları arasında anlamlı farklılık tespit edilmezken, her iki PE grubu kontrol grubuyla ayrı ayrı karşı- laştırıldığında, trombosit, nötrofil, lenfosit ve monosit sayıları ile NLO, TLO, MLO ve TNO değerleri istatistiksel olarak anlamlı farklılık gösterdi. Kontrol ve PE grupları için NLO>3.497 olarak alındığında %51.5 sensitivite, %50.8 spesifisite, %71.9 pozitif prediktif değer, %71.4 negatif prediktif değer elde edilmektedir. Sonuç: Tam kan sayımı parametrelerinin sekonder analizleri sistemik inşamasyon ve bağışıklık durumunu etkin bir şekilde değerlendirmektedir. NLO ve TLO mutlak beyaz kan hücresi sayımları na göre klinik değerlendirme, PE şiddetinin değerlendirilmesi ve PE’nin prognozunun değerlendirilmesi açısından daha etkili göstergeler sunar. Ancak hâlihazırdaki bulgularla sistemik inşamatuar indeksler preeklampsi tanısı koymada ve şiddetini öngörmede yeterli değildirler.
