Neopterin is one of the immunologic biomarkers of several diseases related to activation of the cellular immune system. RSA is associated with immune system related abnormalities. Objectives: We aimed to investigate the effectiveness of neopterin levels in the early diagnosis of RSA. Methods: Eighty RSA patients and forty-three healthy controls were included in the study. The neopterin concentrations were determined by the enzyme-linked immunosorbent assay (ELISA) method. For the statistical analysis, Mann-Whitney U test and Pearson correlation test were used the; p<0.05 was considered statistically significant. Results: Serum mean neopterin levels were 16.47 +/- 0.095 nmol/L in RSA group and 6.14 +/- 0.041 nmol/L in control group, respectively. Compared to the control group, a statistically significant increase (p=0.0183) in the serum neopterin levels of the patients was observed. There was a negative correlation between serum neopterin level and age in both the control (R=0.0774, p=0.6236) and RSA groups (R=0.1415, p=0.2089). However, this correlation was not statistically significant (p>0.05). Conclusions: With overstimulation of interferon-gamma (INF-gamma) during pregnancy, the production of neopterin increases by monocytes/macrophages. The measurement of neopterin levels in the serum contributes to the early diagnosis of pregnancy losses.eninfo:eu-repo/semantics/openAccessPregnancyneopterinINF-gammaConference Object51028103110.12955/cbup.v5.1065WOS:000439408200179N/A
