Atypical onset of antiphospholipid syndrome in pregnancy: a case report.

BACKGROUND: We present a case of an atypical onset of antiphospholipid syndrome (APS). CASE: A woman in her 15th week gestation had a thrombosis of an unknown cerebral cavernoma, which was successfully removed. Twenty-six days after, she was admitted for a severe pain in right hypochondrium and a second class HELLP syndrome was diagnosed. Two days after, she had a fetal loss. After 1 month, laboratory tests revealed high level of antiphospholipid antibodies. At the same time, she developed a spontaneous thrombosis at her right arm. After 6 weeks, antiphospholipid antibodies, tested again, result positive. CONCLUSION: Antiphospholipid antibodies often cause pregnancy complications, but, to our knowledge, this is the first report of an association of antiphospholipid antibodies, with cerebral cavernoma thrombosis and early onset HELLP syndrome.

Cross-sectional and longitudinal evaluation of uterine artery Doppler velocimetry for the prediction of pre-eclampsia in normotensive women with specific risk factors.

OBJECTIVE: To evaluate the performance, in the prediction of pre-eclampsia, of (1) an abnormal mean uterine artery resistance index (RI; cross-sectional index) at 24 weeks of gestation, (2) the individual longitudinal flow pattern of results observed at 16, 20 and 24 weeks of gestation and (3) a multiple logistic regression model including the individual longitudinal flow pattern and the mean RI at 24 weeks. METHODS: A total of 144 normotensive pregnant women with risk factors for pre-eclampsia were evaluated with uterine artery color Doppler at 16, 20 and 24 weeks' gestation. The following indices were obtained: (1) cross-sectional index: the mean RI of both uterine arteries at 24 weeks' gestation was calculated for each patient and considered abnormal when >/= 0.58; (2) longitudinal indices: the individual longitudinal flow pattern of mean RI of both the main uterine arteries at 16, 20 and 24 weeks' gestation was derived for each subject and defined as (a) the typical physiological flow pattern, with a trend of decrease in values or (b) the non-physiological flow pattern. The probability of having a pregnancy complicated by pre-eclampsia was also calculated by means of a multivariate logit model. The log-odds was modeled as a function of variables related to maternal characteristics, the individual longitudinal flow pattern indicator, and of the mean RI at 24 weeks' gestation as a continuous variable. RESULTS: Pregnancies had a physiological course in 108 (75%) women, while 36 (25%) women developed pre-eclampsia during the third trimester. For the prediction of pre-eclampsia, the use of an abnormal uterine artery RI index (> or = 0.58) at 24 weeks showed a sensitivity of 77.8%, a specificity of 67.6%, a positive predictive value (PPV) of 44.4% and a negative predictive value (NPV) of 90.1%, with a likelihood ratio (LR) for an abnormal test of 2.4; with the longitudinal flow pattern indicator, sensitivity was 88.9%, specificity 82.4%, PPV 62.7% and NPV 95.7%, with a LR for an abnormal test of 4.9; the use of a logit model yielded a sensitivity of 72.2%, a specificity of 90.7%, a PPV of 72.2% and a NPV of 90.7%, with a LR for an abnormal test of 8.0. CONCLUSIONS: In this study the use of an individual longitudinal flow pattern indicator resulted in improving accuracy in the prediction of pre-eclampsia as compared with the traditional cross-sectional mean RI at 24 weeks. A further increase in specificity and PPV was obtained using a logit model that includes the longitudinal flow pattern indicator and the cross-sectional RI at 24 weeks. Since both the longitudinal flow pattern indicator and the logit model showed a high performance in predicting pre-eclampsia in women with risk factors for impaired placentation, they might be used to identify a high-risk population in which preventive measures and/or therapeutic options might be tested.

Fetal subcutaneous tissue thickness (SCTT) in healthy and gestational diabetic pregnancies.

OBJECTIVE: To determine reference values of fetal subcutaneous tissue thickness (SCTT) throughout gestation in a healthy population and to compare them with those from a population of pregnant women with gestational diabetes under standard therapy. METHODS: Three hundred and three women recruited from a high-risk pregnancy clinic were classified as being healthy (n = 218) or as having gestational diabetes (n = 85) on the basis of a negative or positive oral glucose tolerance test, respectively. They were enrolled into the cross-sectional study at 20 weeks' gestation. Ultrasound examinations were performed approximately every 3 weeks until delivery at term. The mid-arm fat mass and lean mass (MAFM, MALM), the mid-thigh fat mass and lean mass (MTFM, MTLM), the abdominal fat mass (AFM) and the subscapular fat mass (SSFM) were evaluated. Time-specific reference ranges were constructed from the 218 healthy women and a conventional Student's t-test was performed to compare SCTT values between the two study groups throughout gestation. RESULTS: Normal ranges, including 5th, 50th and 95th centiles of the distribution, were generated for each SCTT parameter obtained in each of the two groups of women. Significant differences were found between the two study groups at 37-40 weeks' gestation for MTFM, at 20-22 and 26-28 weeks for MTLM, at 31-34 and 35-37 weeks for MAFM, at 26-28 and 38-40 weeks for SSFM, and at 39-40 weeks for AFM, the mean residual values always being greater in gestational diabetic women than they were in the group of healthy pregnant women. CONCLUSIONS: We provide gestational age-specific reference values for fetal SCTT. Fetal fat mass values, particularly in late gestation, are greater in women with gestational diabetes compared with healthy women. The reference values may have a role in assessing the influence of maternal metabolic control on fetal state.

Individual longitudinal patterns in biochemical and hematological markers for the early prediction of pre-eclampsia.

OBJECTIVE: To analyze the individual longitudinal patterns of maternal biochemical and hematological tests performed throughout gestation in order to predict at the 20th week of pregnancy the later development of pre-eclampsia. STUDY DESIGN: A longitudinal study was conducted on 187 white normotensive pregnant women all with a history of pre-eclampsia. Blood samples were performed at the 8th week of gestation and then every 4 weeks until the 36th week. The longitudinal patterns of urea, creatinine, uric acid, total proteins, hematocrit, red blood cells, hemoglobin, mean red cell volume, ferritin and iron were derived. By means of regression analysis, for each woman and each significant marker, a 'theoretical physiological pattern', from the 8th to the 20th week, was constructed. By comparing the observed values of each marker for each woman with her 'theoretical physiological pattern', variables indicating the match or mismatch to it were derived. Such variables were used, together with other maternal characteristics, in a logit regression for the probability of developing pre-eclampsia later in pregnancy. RESULTS: In 140 cases, pregnancies followed a physiological course, while 47 women developed pre-eclampsia during the third trimester. In the physiological gestations, the weekly mean values of creatinine, hematocrit, total proteins, uric acid and urea showed patterns that were significantly different from those of the pathological group. The logit model was able to classify correctly 96% of the physiological and 87% of the pathological pregnancies, with a negative predictive value of 96% and a positive predictive value of 89% (area under the receiver operator characteristics (ROC) curve 0.98). The ability of the model to predict later complications at the 20th week was confirmed by a validation procedure. CONCLUSION: The simultaneous use of individual longitudinal patterns of parameters, achieved non-invasively as part of the standard methods of antenatal care that provide a global evaluation of plasma volume expansion, showed a high ability to predict, early in pregnancy, the later development of pre-eclampsia.

Time course of recovery and complications of HELLP syndrome with two different treatments: heparin or dexamethasone.

HELLP syndrome is a severe complication of pregnancy characterized by microangiopathic hemolytic anemia, hepatic dysfunction and thrombocytopenia. Though delivery is the ultimate therapeutic option, medical treatments, including the use of heparin or corticosteroids, have been employed in the attempt to improve maternal prognosis. The aim of this retrospective study was to compare the time course of recovery and the incidence of complications in women with HELLP syndrome receiving either heparin or dexamethasone. Between January 1990 and December 1998, 32 patients with HELLP syndrome were cared for at the Institute of Obstetrics and Gynecology of the University of Florence: 20 patients were treated with heparin, administered subcutaneously at a dose of 5000 IU every 12 h, whereas 12 women received dexamethasone, administered intravenously at a dose of 10 mg every 12 h. Categorical data were evaluated with chi-square and Fisher's exact test; continuous data were analyzed with Mann-Whitney U test; P < .05 was considered significant. In the subgroup treated with heparin the incidence of disseminated intravascular coagulation (DIC) (P < .02), the number of patients requiring blood transfusion (P < .05) and the length of stay at the Intensive Care Unit (ICU) (P < .04) were significantly increased as compared with the subgroup receiving dexamethasone; in this latter subgroup, significantly higher platelet count and hematocrit values, and significantly lower levels of lactate dehydrogenase (LDH) could be documented starting from day 2 after delivery. The results of our investigation suggest that the use of dexamethasone in patients with HELLP syndrome is associated with faster regression and lower incidence of complications in comparison to heparin.

Cardiovascular function in pregnancy: effects of posture.

OBJECTIVE: To evaluate the cardiovascular response to active postural changes in pregnancy. DESIGN: Prospective study. SETTING: Outpatient Clinic, Fetal Maternity Unit. PARTICIPANTS: Sixteen healthy women referred prior to pregnancy. METHODS: Heart rate, arterial pressure, echocardiographic end-diastolic and end-systolic left ventricular volumes (Teichholz' s formula) were measured in the three months before pregnancy, at the end of the first and second trimester, at mid third trimester, and six months after delivery in the supine and standing position, in thirteen women (mean age 33, range 25-38 years). RESULTS: Cardiac output (supine position) significantly increased (28%): it reached its maximum at the second trimester, remained steadily elevated in the mid third trimester, and returned to baseline after delivery. Cardiac output increased during pregnancy also in the active orthostatic position, the percentage increase being greater (70%) since the standing pre-conception value was lower. The postural stress induced similar changes in heart rate, arterial pressure and left ventricular ejection fraction before, during and after pregnancy. However, the reduction in cardiac output associated with early standing attenuated significantly at the second trimester and it was absent at mid third trimester (F = 3.13, P = 0.021). This was due to the interplay between the significantly lesser increase in systemic vascular resistance, occurring since the first trimester, and the significantly lesser decrease in left ventricular end-diastolic volume which was observed in the mid third trimester. CONCLUSION: These data indicate that the elevated cardiac output is adequately maintained in pregnancy during the postural challenge, due to optimisation of the responses of preload and afterload.

Prediction of the development of pregnancy-induced hypertensive disorders in high-risk pregnant women by artificial neural networks.

Pregnancy-induced hypertensive disorders (PIHD) are common complications of pregnancy and are associated with increased maternal and fetal morbidity. In this study, artificial neural networks (aNN) and multivariate logistic regression (MLR) were applied to a set of clinical and laboratory data (urea, creatinine, uric acid, total proteins, hematocrit, iron and ferritin) collected at 16 and 20 weeks of gestation. The efficacy of the two approaches in predicting the development of PIHD in 303 consecutive normotensive pregnant women at high risk of pre-eclampsia and intrauterine fetal growth retardation was then compared. The aNN were trained with a randomly selected set of 187 patient records and evaluated on the remainder (n=116). MLR analysis was done with the same 116 patients. The performance of each model was assessed using receiver operator characteristic (ROC) curves. Pregnancies had a normal physiological course in 227 cases, whereas 76 (25.1%) women developed PIHD during the third trimester. The best aNN at 20 weeks yielded an area under the ROC curve of 0.952, the sensitivity of 86.2%, the specificity of 95.4%, the positive predictive value of 86.2% and the negative predictive value of 95.5% for PIHD. The corresponding values for the MLR at 20 weeks were 0.962, 79.3%, 97.7%, 92% and 93.4%, respectively. The computer-aided integrated use of these conventional tests seems to provide a useful means for and early prediction of PIHD development.

Third-trimester maternal glucose levels from diurnal profiles in nondiabetic pregnancies: correlation with sonographic parameters of fetal growth.

OBJECTIVE: To assess the 24-h glucose levels in a group of nondiabetic, nonobese pregnant women and to verify the presence of correlations between maternal glucose levels and sonographic parameters of fetal growth. RESEARCH DESIGN AND METHODS: A total of 66 Caucasian nonobese pregnant women with normal glucose challenge tests (GCT) enrolled in the study; from this population, we selected 51 women who delivered term (from 37 to 42 weeks completed) live-born infants without evidence of congenital malformations. The women were requested to have three main meals and to perform daily glucose profiles fortnightly from 28-38 weeks without modifying their lifestyle or following any dietary restriction. All subjects were taught how to monitor their blood glucose by using a reflectance meter. Fetal biometry was evaluated by ultrasound scan according to standard methodology at 22, 28, 32, and 36 weeks of pregnancy. RESULTS: The overall daily mean glucose level during the third trimester was 74.7 +/- 5.2 mg/dl. Daily mean glucose values increased between 28 (71.9 +/- 5.7 mg/dl) and 38 (78.3 +/- 5.4 mg/dl) weeks of pregnancy. We found a significant positive correlation at 28 weeks between 1-h postprandial glucose values and fetal abdominal circumference (AC). At 32 weeks, we documented positive correlations between fetal AC and maternal blood glucose levels 1 h after breakfast, 1 and 2 h after lunch, and 1 and 2 h after dinner. At 36 weeks, there was a positive correlation between fetal AC and 1- and 2-h postprandial blood glucose levels. In addition, there was a negative correlation between head-abdominal circumference ratio and 1-h postprandial blood glucose values. CONCLUSIONS: This longitudinal study first provides a contribution toward the definition of normoglycemia in nondiabetic, nonobese pregnant women; moreover, it reveals significant correlations of postprandial blood glucose levels with the growth of insulin-sensitive fetal tissues and, in particular, between 1-h postprandial blood glucose values and fetal AC.

Thyroid autoimmunity and its association with non-organ-specific antibodies and subclinical alterations of thyroid function in women with a history of pregnancy loss or preeclampsia.

Following the observation that non-organ-specific antibodies are related with pregnancy loss and preeclampsia, the role of organ-specific antibodies is currently being extensively investigated. The aim of this study was on the one hand to evaluate the incidence of antithyroid antibodies in a study group of 69 women with a history of early pregnancy loss (subgroup 1), foetal death (subgroup 2) or preeclampsia (subgroup 3) and in a control group, on the other hand to assess the possible association of these autoantibodies with non-organ-specific antibodies and subclinical alterations of thyroid function in the study group. Antithyroid antibodies were present in 26/69 (37.7%) women of the study group (37.9% in subgroup 1; 40.9% in subgroup 2; 33.3% in subgroup 3) and in 10/69 (14.5%) of controls, the difference being statistically significant. A significant difference in the distribution of antibodies to thyroglobulin and thyroid peroxidase was found in subgroup 2. In the study group, the incidence of antiphospholipid antibodies was not significantly different in women positive (26.9%) and negative (34.9%) for antithyroid antibodies. Also, the overall incidence of subclinical alterations of thyroid function in the study group was significantly different in women positive (53.8%) and negative (16.2%) for thyroid autoimmunity (P<0.02). The results of this study seem to confirm the association between thyroid autoimmunity and obstetric complications and suggest the usefulness of undertaking prospective studies in order to evaluate the reproductive outcome of women with a history of recurrent abortion, foetal death or preeclampsia and positivity for antithyroid antibodies.

Angiotensin-converting enzyme DD genotype, angiotensin type 1 receptor CC genotype, and hyperhomocysteinemia increase first-trimester fetal-loss susceptibility.

Complications of pregnancy have been found to be related with thrombophilic polymorphisms that explain about 30% of obstetric complications. We evaluated the angiotensin converting enzyme (ACE) and the angiotensin type 1 receptor (AT1R) gene polymorphisms in the renin-angiotensin system (RAS) as possible risk factors for fetal loss. Fifty-nine women with a history of three or more first-trimester fetal losses and 70 healthy women with a history of normal pregnancies were enrolled in this study. Thrombophilic factors, ACE insertion/deletion (I/D) and AT1R A1166C polymorphisms, prothrombin G20210A and factor V Leiden mutations were analyzed. At univariate and multivariate analysis, a significant association between ACE DD and AT1R CC genotype and fetal loss was observed. The effect of the ACE DD genotype on the risk of fetal loss was higher in AT1R C allele carriers. The prevalence of hyperhomocysteinemia (Hcy) (defined as baseline plasma levels higher than the 95% percentile; cut-off, 10.5 micromol/l per l) was significantly higher in women with fetal loss, and an association between Hcy and fetal loss was detected. All patients showed normal antithrombin, protein C, protein S, and plasminogen activator inhibitor-1 (PAI-1) values. The presence of one risk factor not associated with others was found in 33 out of 59 patients (56%); ACE DD genotype was the most prevalent risk factor. Our results identify new possible predictive markers for fetal loss in RAS polymorphisms and Hcy. Large-scale studies are warranted to attribute clinical relevance to these polymorphisms as risk factors for complicated pregnancies.

What degree of maternal metabolic control in women with type 1 diabetes is associated with normal body size and proportions in full-term infants?

OBJECTIVE: To assess what degree of maternal metabolic control in women with type 1 diabetes is associated with normal fetal growth and results in normal neonatal body proportions in a group of full-term infants. RESEARCH DESIGN AND METHODS: We investigated the anthropometric characteristics of 98 full-term singleton infants born to 98 Caucasian women with type 1 diabetes enrolled within 12 weeks of gestation. The type 1 diabetic mother-infant pairs were divided into three groups on the basis of the daily glucose levels reached during the second and third trimesters of pregnancy (group 1: 37 mother-infant pairs with an average daily glucose level during the second and third trimesters of < or =95 mg/dl; group 2: 37 mother-infant pairs with an average daily glucose level during the second trimester of >95 mg/dl and during the third trimester of < or =95 mg/dl; group 3: 24 mother-infant pairs with an average daily glucose level during the second and third trimesters of >95 mg/dl; control group: 1,415 Caucasian mother-infant pairs with full-term singleton pregnancies and normal glucose challenge test screened for gestational diabetes. RESULTS: Infants of diabetic mothers in group 1 were similar to those of the control group in birth weight and in other anthropometric parameters. In contrast, offspring of diabetic mothers of groups 2 and 3 showed an increased incidence of large-for-gestational-age infants, significantly greater means of ponderal index and thoracic circumferences, and significantly smaller cranial/thoracic circumference ratios with respect to the control group. CONCLUSIONS: The results of our study suggest that, in diabetic pregnancies, only overall daily glucose values < or =95 mg/dl throughout the second and third trimesters can avoid alterations in fetal growth.

[Acute pericarditis in pregnancy. Report of a case].

In this study the authors describe a case of acute pericarditis occurring at 26 weeks' gestation in a woman affected by Wolff-Parkinson-White Syndrome and with a history of Hodgkin's Lymphoma and autoimmune hypothyroidism. The patient was first admitted to the 4th Medical Pathology Unit of the University of Florence, where moderate pericardic effusion with no evidence of heart tamponade was documented by ultrasound scan. Subsequently the patient was cared for on outpatient basis at the Centre of Perinatal Medicine of the Department of Obstetrics and Gynaecology of the University of Florence. Since all examinations and tests aimed at defining the etiology of pericardial effusion were negative, an idiopathic acute pericarditis was diagnosed. The patient was given prednisone at a dose of 75 mg per day; owing to episodes of paroxystic atrial fibrillation, propaphenon was also administered intravenously to treat acute episodes and orally as prophylaxis. The patient underwent close control of both heart function (by means of ultrasound scans of the heart and dynamic EKG) and pregnancy (blood tests, ultrasound scans and Doppler velocimetry). At 36.5 weeks' gestation a healthy fetus was spontaneously delivered. Three months after delivery, the patient underwent an ultrasound scan that demonstrated the complete reabsorption of the effusion.

Usefulness of screening for congenital or acquired hemostatic abnormalities in women with previous complicated pregnancies.

Activated protein C resistance (APCR) is a common cause of familial thrombophilia and venous thrombosis. The aim of the study was to investigate the prevalence of APCR associated with factor V Leiden mutation and its relevance in comparison to other risk factors for thromboembolic disorders in women with a history of previous complicated pregnancies (history of fetal loss in the second and third trimester n = 34, preeclampsia n = 46). The frequency of APCR was significantly higher in women with a history of fetal loss and preeclampsia (23.5 and 26.1%, respectively) compared with a control group (3.8%). The prevalence of antithrombin, protein C and protein S deficiencies and the presence of antiphospholipid antibodies were also investigated: the prevalence of at least one disorder was 41.2% in the group with previous fetal loss, 37.0% in the group with previous preeclampsia and 7.5% in the control group.

Reproducibility of ambulatory blood pressure monitoring results in pregnancy.

Blood pressure (BP) differences between two consecutive 24-h monitoring periods (P1, P2) were analyzed in 159 hospitalized pregnant women. Reproducibility index, or twice the standard deviation of differences between individual systolic and diastolic means, was better for 24-h (7.8 and 5.8) and daytime (8.7 and 6.3) than for nighttime (12.2 and 9.7) BP means. It did not depend on BP level or gestation week. Alert reaction to monitoring procedure increased BP only in the first 2 h of P1. The high overall reproducibility of ambulatory BP in pregnancy supports the expanding use of the technique also in this condition.

[Kidney transplantation and pregnancy. Report of a case].

The aim of this study was to evaluate the extent to which the presence of a transplanted kidney conditions the physiological renal and maternal cardiocirculatory adaptation to pregnancy. For this purpose, we compared the trend of cardiocirculatory and renal hematochemical parameters in a kidney-transplant patient to a group of 100 physiological pregnant women followed longitudinally. M. G., aged 36, primigravida, who underwent renal transplantation ten years before, was carefully monitored throughout gestation. Pregnancy was free of complications and ended at 38 weeks with an elective caesarian section. The trend of the parameters mirrored the physiological pattern, even if the values for some renal parameters were completely different. This type of comparison enabled us to evaluate the adaptation of the transplanted organ and the body to pregnancy and to formulate a prognostic judgement halfway through pregnancy regarding the outcome.

D-dimer plasma levels during normal pregnancy measured by specific ELISA.

A progressive increase in D-dimer plasma levels together with an increase in fibrinogen has been previously reported during normal pregnancy. However, significantly different D-dimer levels have been observed in different assays, due to different specificity of the antibodies employed. The aim of this study was to verify the increase in fibrin degradation product levels during normal pregnancy, using a recently introduced specific D-dimer ELISA. We determined D-dimer (ELISA) and fibrinogen (clotting method) plasma levels in 63 normal pregnant women, during three different periods of pregnancy (A, 7-20 weeks; B, 21-30 weeks; C, > 30 weeks). During period A, D-dimer plasma levels (range 2-103 ng/ml) showed an insignificant increase compared with a control group of non-pregnant women (range 2-73 ng/ml). During periods B and C, we observed an increase in D-dimer level (P < 0.0001) compared with period A, with a significant correlation between D-dimer levels and gestational age (P < 0.0001). Period A fibrinogen levels (range 3.24-6.43 g/l) were significantly higher (P < 0.0001) than in controls (range 2.31-4.71 g/l), with a further increase in periods B and C. In conclusion, we confirmed a progressive increase in plasma concentrations of fibrin degradation product during normal pregnancy, but D-dimer levels were significantly lower than those reported in the literature for other ELISAs.

Anthropometric features in infants of mothers with gestational diabetes: relationship with treatment modalities.

We compared the effects of two treatment strategies (diet alone versus a combination of insulin and diet) on neonatal anthropometric measurements and the outcome of a full-term white infant sample born to mothers with gestational diabetes mellitus (GDM). Study subjects included 217 consecutive nonrandomized women with GDM with term singleton pregnancies. Insulin therapy was administered on the basis of anamnestic and maternal-fetal criteria. One hundred and twenty-one patients (group 1) received a combination of insulin and diet, and 96 (group 2) underwent diet alone. All 1,052 white patients with term singleton pregnancies without GDM, screened at the same time as the study group, formed the control group. The incidence of large-for-gestational-age (LGA) infants was significantly higher in group 2 (18.8%) compared with group 1 (9.9%) and the control group (8.3%). Male and female infants born to diabetic mothers of group 2 had significantly greater mean birth weights, ponderal indices, thoracic circumferences, weight/length ratios and significantly smaller mean cranial/thoracic circumference ratios than male and female infants in group 1 and the control group (p < 0.05, Scheffe test). Treatment of GDM mothers with insulin and diet has been shown to be able not only to normalize the incidence of LGA infants but also to influence the anthropometric characteristics of the infants born to these mothers to such an extent that they showed no significant differences compared to infants born to non-diabetic mothers.
