Echocardiographic findings of congenital cardiopathies among fetuses of diabetic pregnant women and their relationship with plasma fructosamine levels.

Abstract

OBJECTIVE:

To study the occurrence of congenital cardiopathies at echocardiography (CCE) in fetuses whose mothers had preexisting diabetes mellitus (PGDM) and to study the potential of using fructosamine level as a late marker (beyond the first trimester) for CCE.

METHODS:

A register study covering 91 pregnant women that underwent routine fetal echocardiography ordered due to PGDM. The first dosage of plasma fructosamine found in 65 medical records was analyzed during prenatal care (20.4 ± 8.0 weeks of gestation). The presence or absence of structural or functional CCE was associated with fructosamine levels by logistic regression. We assessed the effect modification odds ratio by maternal age and insulin usage.

RESULTS:

Thirty-four fetuses (52.3% of 65 fetuses) presented CCE. Twenty of them had functional CCE and 14 presented structural CCE. The mean maternal plasma fructosamine level was higher among pregnant women whose fetuses presented CCE than in those whose fetuses did not (2.86 ± 0.73 mmol/l, 2.22 ± 0.54 mmol/l, respectively, p < 0.0001). Crude OR for CCE and abnormal plasma fructosamine (>2.68 mmol/l) was 9.6 (2.8-33.7, 95% CI, p < 0.0001). Adjusted OR by maternal age and insulin usage was 10.9 (2.7-45.2, 95% CI p < 0.0001).

CONCLUSIONS:

An abnormal plasma fructosamine level increases the chances of CCE occurring among referral pregnant women with PGDM.
