Evaluation of Maternal Serum 25-Hydroxyvitamin D, Paraoxonase 1 Levels, and Neutrophil-to-Lymphocyte Ratio in Spontaneous Preterm Birth.

BACKGROUND The aim of this study was to evaluate the association of maternal serum 25-hydroxyvitamin D, paraoxonase 1, and neutrophil-to-lymphocyte ratio in women having early spontaneous preterm birth without clinical chorioamnionitis. MATERIAL AND METHODS This study was prospectively administered in women referred to our obstetrics service with preterm labor that resulted in preterm birth (n=35) and term labor that ended in term birth (n=44). The maternal serum levels of 25-hydroxyvitamin D and paraoxonase 1 were measured and neutrophil-to-lymphocyte ratio was calculated.

Evaluation of cytokines as Th1/Th2 markers in pathogenesis of children with Crimean-Congo hemorrhagic fever.

Cytokine networks play a key role in the pathogenesis of the disease in Crimean-Congo Hemorrhagic Fever (CCHF) patients. Therefore, our aim was to study the effects of cytokine levels on the pathogenesis and severity of the disease in children with CCHF. Fifty-two patients diagnosed with CCHF and 34 healthy controls (HC) were included in the study.
