Objective:
We examined serum ischaemia-modified albumin (IMA) levels in normal pregnant and preeclamptic women. The primary aim of our study was to assess IMA in women with mild and severe preeclampsia.
Methods:
Serum ischaemia-modified albumin levels were measured in 18 normotensive and 36 preeclamptic pregnant women by enzyme linked immuno-sorbent assay. Patients were subdivided as having either mild (n=18) or severe preeclampsia (n=18). Receiver operating characteristic curve was constructed, and sensitivity and specificity were calculated based on the best cut-off.
Results:
IMA levels were significantly higher in the mild and severe preeclamptic groups than in the control group. IMA with a cut-off point of 0.31 identified women with preeclampsia with sensitivity 80% and specificity 77.8%.
Conclusion:
Our study demonstrates that serum levels of IMA correlate with severity of preeclampsia.
