Although exact cause of this condition is still a matter of debate, contribution of oxidative stress to pathogenesis of HEG was demonstrated in some studies. The aim of this study was to investigate the diagnostic value of ischemia-modified albumin (IMA) concentration and IMA/albumin ratio (IMAR) in HEG patients. Methods: One patient group and two control groups were constituted. Pregnant subjects with HEG were included in HEG group (n=31) and age-, gestational age-, and body mass index (BMI)-matched healthy pregnant women in control group (n=30). The second control group was constituted from age- and BMI-matched non-pregnant women (n=30). Serum IMA, IMAR blood glucose, albumin, urea, creatinine, alanine aminotransferase and aspartate aminotransferase levels were measured in all subjects. Results: Serum median IMA levels [0.55 (0.43-0.68)] was found to be elevated in HEG patients compared with pregnant [0.52 (0.34-0.61)] and non-pregnant controls [0.48 (0.27-0.57)] (p=<0.001). IMAR levels were also found to be significantly elevated in HEG patients compared to both control groups. According to correlation analysis, IMA and IMAR levels were only correlated with C-reactive protein levels. Conclusion: Elevated levels of IMA and IMAR in HEG patients might be due to ischemic intrauterine environment.trinfo:eu-repo/semantics/openAccessHyperemesis gravidarumischemia-modified albuminischemia-modified albumin/albumin ratiooxidative stressArticle56429229810.4274/haseki.4019N/AWOS:0004549619000062-s2.0-85059580550297297Q3
