Diagnostic accuracy of spot albumin creatinine ratio and its association with fetomaternal outcome in preeclampsia and eclampsia.

Introduction: Hypertensive disorders in pregnancy are one of the leading causes of maternal and perinatal mortality. Proteinuria is one of the common and important features of preeclampsia. To evaluate the diagnostic accuracy of albumin-creatinine ratio (ACR) in woman with preeclampsia and eclampsia and examine the association between ACR and fetomaternal outcome.

Materials And Methods: Prospective study carried out over a period of 1 year in the Department of Obstetrics and Gynaecology, after informed consent and ethical clearance total ninety pregnant women from gestational age 20 to 40 weeks were enrolled, including, thirty preeclampsia, thirty antepartum eclampsia, considered as cases and thirty normotensive pregnant women as controls. Preeclampsia was defined as per National High Blood Pressure Education Program 2000 working group. All patients were asked for a spot midstream urine sample, followed by 24 h urine collection. Urinary protein was estimated by the sulfosalicylic acid method and creatinine by the Jaffe's method. The urinary ACR was determined by automated analyzer.

Results: Mean value of urinary ACR of controls was significantly lower (0.103 ± 0.037) as compared to both groups. On comparing between groups the difference was significant (<0.001), a strong correlation between urinary ACR levels and 24 h urinary proteins was observed.

Conclusion: In our study, an association of raised ACR values with severity of disease as well as with adverse fetomaternal outcome was observed.
