Methods: About 126 women who delivered in the Larissa University Hospital were divided in three groups: iron-deficiency anemia (n=39), β-thalassemia trait carriers (n=53) and control group (n=34). HIF-1α expression was assessed with immunochemical assays and statistical analysis was performed with chi-squared test and ANOVA. Results: HIF-1α immunostaining was intense in the two groups of anemia. A statistically significant association was found between HIF-1α immunoreactivity and hematocrit (p<0.001), hemoglobin (p<0.001), MCV (p<0.001), transferrin (p<0.001) and its receptors (p=0.040), whereas no significant correlations were observed between HIF-1α, iron serum levels (p=0.256) and ferritin (p=0.232). We found no association between HIF-1α and birthweight (p=0.256), placental weight (p=0.870) and Apgar score at 1′ (p=0.210) and 5′ (p=0.400). Conclusions: HIF-1α expression is affected by anemia, although this factor has no important direct effect on the perinatal outcome. © 2014 Informa UK Ltd.
