Hyperemesis gravidarum is associated with increased maternal serum ischemia-modified albumin.

AIM: Our objective was to measure the circulating levels of ischemia-modified albumin (IMA) among pregnant with hyperemesis gravidarum (HEG) and to compare their levels with age- and body mass index (BMI)-matched control pregnant women.

METHOD: The pregnant subjects were classified into the HEG group diagnosed with HEG (n=45) and age- and BMI-matched control group without a diagnosis of HEG (n=45) during their pregnancies. Serum IMA, hemoglobin, hematocrit, white blood cells, platelet, fasting blood glucose, creatinine, lipid profile, aspartate aminotransferase (AST) urea, alanine aminotransferase (ALT), sodium, potassium and thyroid-stimulating hormone (TSH) levels of the groups were measured.

RESULT: Serum hemoglobin, hematocrit, white blood cells, platelet, fasting blood glucose, creatinine, lipid profile, AST, urea, ALT, sodium, potassium and TSH levels of the groups were statistically similar. Serum IMA values were significantly higher in subjects with HEG compared to the subjects without HEG.

CONCLUSIONS: We found that HEG was related to increased maternal serum IMA levels. HEG might be due to an ischemic intrauterine environment leading to elevated serum IMA concentrations.
