Abstract (2. Language):
Objective: Cytokines appear to contribute to the maintenance of normal pregnancy and development of pathological
conditions. The aim of this study was to evaluate plasma cytokine pattern in preeclampsia and whether there is
any relationship with disease severity or not.
Materials and methods: Plasma samples of 65 women (25 healthy nonpregnant (NP), 20 normotensive pregnant
(NTP) and 20 preeclamptic pregnant (PEP) women) were investigated by means of TNFα, IL-1β, IL-12, IL-4 and
IL-10 concentrations. Statistical significance was analysed by Student’s t-, Kruskal- Wallis, Mann-Whitney U- and
Spearman correlation tests.
Results: In PEP in comparison with NP women, together with elevation of pro-inflammatory TNFα, IL-1β and
IL-12 (Th1 cytokines), there is an increase of anti-inflammatory IL-4 and IL-10 (Th2 cytokines). In addition, there
is an increase of anti-inflammatory IL-4 and IL-10 levels in PEP in comparison with NTP. Among the preeclamptic
group there is a significant positive correlation between IL-1β/IL-10 and TNFα/IL-12; also, a significant negative
correlation between IL-4/systolic blood pressure, IL-4/LDH.
Conclusions: The rise of anti-inflammatory cytokines probably is a compensatory mechanism by which IL-4 and
IL-10 counteract to pro-inflammatory cytokines, and thus balance their endothelium destroying effects. The presence
of negative correlation between anti-inflammatory cytokines and blood pressure or some liver enzymes suggests
that there is probably a relationship between plasma cytokines and disease severity. On the other hand, elevated maternal
plasma IL-4 and IL-10 concentrations in preeclampsia may be a response to improve altered Th1/Th2 balance
and to protect from maternal immunorejection

Amaç: Sitokinler normal gebeli¤in sürdürülmesi ve patolojik durumlar›n ortaya ç›kmas›nda önemli rol oynar. Bu
çal›flmada preeklampside plazma sitokin paternini incelemek ve hastal›¤›n seyri ile bir iliflkisi olup olmad›¤›n› de-
¤erlendirmek hedeflenmifltir.
Gereç ve yöntem: 25’i sa¤l›kl› ve gebe olmayan (NP), 20’si normotensif gebe (NTP), ve 20’si preeklamptik gebe
(PEP) olmak üzere toplam 65 kad›n›n plazma örneklerinde TNFα, IL-1β, IL-12, IL-4 ve IL-10 konsantrasyonlar›
tayin edildi. ‹statistiksel de¤erlendirme Student’s t-, Kruskal-Wallis, Mann-Whitney U- ve Spearman korelasyon
testleri ile gerçeklefltirildi.
Bulgular: NP kad›nlara k›yasla, PEP’de pro-inflamatuar ve Th1 sitokinleri olan TNFα, IL-1β, IL-12 art›fl› ile birlikte
anti-inflamatuar ve Th2 sitokinleri olan IL-4 ve IL-10 de artmaktad›r. Bununla birlikte, NTP’ye k›yasla PEP’de
anti-inflamatuar IL-4 ve IL-10 düzeyleri artmaktad›r. Preeklampsi grubunda IL-1β/ IL-10; TNFα/IL-12 aras›nda
pozitif; IL-4/sistolik kan bas›nc› ve IL-4/LDH aras›nda ise negatif korelasyon bulundu. Sonuçlar: Anti-inflamatuar sitokin art›fl› pro-inflamatuar sitokinlerin neden oldu¤u endotel disfonksiyonuna karfl›
koyan bir kompensatuar mekanizma olabilir. Anti-inflamatuar sitokinler ile kan bas›nc› veya baz› karaci¤er enzimleri
aras›nda bulunan negatif korelasyon, plazma sitokin düzeyleri ve hastal›¤›n seyri aras›nda bir iliflki olabilece¤ini
ortaya koymaktad›r. Bununla birlikte, preeklampside anne plazmas›nda IL-4 ve IL-10 konsantrasyonlar›n›n art›-
fl›n›n, Th1/Th2 sitokin dengesini etkileyerek, maternal imünorejeksiyondan korumaya çal›flan bir cevap oldu¤unu
söyleyebiliriz.
