Abstract
OBJECTIVE There is compelling evidence that insulin resistance may play a pivotal role in the development of pregnancy complications including pre-eclampsia and intrauterine growth restriction (IUGR). As dysregulation of visfatin and adiponectin is found in insulin resistance, both adipokines might contribute to pregnancy disorders. PATIENTS AND METHODS Plasma levels of visfatin and adiponectin were quantified in second-trimester pregnancies with abnormal uterine perfusion and in third-trimester pregnancies with IUGR as compared to healthy controls. RESULTS Mean plasma adiponectin levels were significantly increased in women with pathological perfusion (7078 +/- 789 ng/ml) as compared to normal uterine perfusion (4481 +/- 1183 ng/ml) (P < 0.05) whereas visfatin plasma concentrations were not different between these groups. Visfatin levels were significantly elevated in women with IUGR (140.1 +/- 10 ng/ml) as compared to patients with normal outcome (65.5 +/- 11 ng/ml) (P < 0.05). By contrast, adiponectin plasma concentrations were not significantly altered in women with IUGR. CONCLUSIONS Our data support the view that the adipokines visfatin and adiponectin are differentially regulated in pregnancy complications.

Abstract
Pre-eclampsia (PE) is a serious disorder with high morbidity and mortality occurring during pregnancy; 3%-5% of all pregnant women are affected. Early prediction is still insufficient in clinical practice. Although most pre-eclamptic patients show pathological uterine perfusion in the second trimester, this parameter has a positive predictive accuracy of only 30%, which makes it unsuitable for early, reliable prediction. The study is based on the hypothesis that alterations in cardiovascular regulatory behavior can be used to predict PE. Ninety-six pregnant women in whom Doppler investigation detected perfusion disorders of the uterine arteries were included in the study. Twenty-four of these pregnant women developed PE after the 30th week of gestation. During pregnancy, additional several noninvasive continuous blood pressure recordings were made over 30 min under resting conditions by means of a finger cuff. The time series extracted of systolic as well as diastolic beat-to-beat pressures and the heart rate were studied by variability and coupling analysis to find predictive factors preceding genesis of the disease. In the period between the 18th and 26th weeks of pregnancy, three special variability and baroreflex parameters were able to predict PE several weeks before clinical manifestation. Discriminant function analysis of these parameters was able to predict PE with a sensitivity and specificity of 87.5% and a positive predictive value of 70%. The combined clinical assessment of uterine perfusion and cardiovascular variability demonstrates the best current prediction several weeks before clinical manifestation of PE.
