Obstetric complications recorded prospectively were assessed retrospectively in 150 women with gestational diabetes mellitus (GDM) and 305 control subjects matched for age, parity, and ethnicity. Intensive diet therapy and self-monitoring of capillary blood glucose were used to obtain postprandial euglycemia; 22% of GDM subjects required insulin. GDM and control subjects were grouped by body mass index to detect any influence of maternal prepregnancy weight on outcome. Polyhydramnios, preterm labor, and pyelonephritis were not more frequent in GDM, but hypertension without proteinuria (7.3 vs. 3.3%) and preeclampsia (8 vs. 3.9%) were more frequent in GDM. The frequency of hypertensive complications in GDM was not totally attributable to being overweight. Abnormalities of labor, birth trauma, and fetal macrosomia were not more common in GDM; 6.7% of the infants of mothers with GDM weighed greater than 4200 g at birth compared with 3.6% of control infants (NS), and 10% were large for gestational age and sex compared with 6.6% of control infants (NS). Despite this, cesarean delivery was more common in GDM (35.3 vs. 22%, P less than 0.01), mostly due to significantly more cesarean births without labor.

The 50 g oral glucose challenge test (50gGCT) was performed on 622 pregnant women, and 75 g oral glucose tolerance test (75gGTT) was further done on subjects with screening tests value of > or = 7.78 mmol/L. The results showed that there were 16.56% (103/622) women with screening value of > or = 7.78 mmol/L, among whom, 32 were identified as having gestational impaired glucose tolerance (GIGT) and 12, gestational diabetes mellitus (GDM) by confirmatory test of 75gGTT. The sensitivity of 50gGCT was 42.72%(44/103). The incidences of edema-proteinuria-hypertension syndrome (EPH-syndrome), premature rupture of membranes, fetal macrosomia, operative deliveries and perinatal morbidity were higher in women with GIGT/GDM than in women without GIGT/GDM. It suggests that 50gGCT is an ideal method of screening for GDM and should be performed on all pregnant women.

The object of this study was to investigate the relationship of thrombomodulin (TM) and glycosylated hemoglobin (HbA1C) in pregnant diabetics and to determine clinical correlates. We performed a prospective cohort study of 53 patients: 25 women with insulin-dependent diabetes (group 1) and 28 with gestational diabetes (group 2). Group 1 underwent monthly determinations of HbA1C and TM. Group 2 underwent determination at 36 weeks of gestation. There was a significant difference in HbA1C between groups 1 and 2 (p=0.0005), but there was no difference in TM. There was no correlation between TM and HbA1C. TM levels correlated positively with serum creatinine (r=0.46, p=0.002), proteinuria (r=0.48, p=0.007), and duration of diabetes (r=0.41, p=0.042). TM was significantly higher in diabetics of advanced White Classification (p=0.008). With good control, TM does not appear to be elevated in a diabetic pregnancy. TM may be a marker of endothelial damage that correlates more with duration of diabetes and renal disease than with HbA1C, which reflects short-term control.

This study sought to quantify the familial risk of preeclampsia (proteinuric hypertension) in Newfoundland and to identify characteristics in probands that predict increased familial risk. Reviewed were 5173 obstetric charts from 10 hospitals, representing 99% of deliveries on the island of Newfoundland for a 1-yr period from April 1996 to March 1997; pregnancy-induced hypertension was diagnosed according to strict criteria. Family obstetric histories were obtained from identified probands with preeclampsia, and sisters and mothers of probands were interviewed. In addition, the obstetric charts from sisters and mothers were reviewed to identify preeclampsia. The incidence of preeclampsia in the population was 5.6% (n = 292), and in primiparous women it was 7.9%. Factors independently associated with increased risk of preeclampsia included primiparous delivery, multiple gestation, pregestational and gestational diabetes, maternal age of more than 35 yr, and region of the province. Of 330 sisters identified, 217 had 445 pregnancies, with 331 charts located for review. The incidence of preeclampsia (based on chart review) in 163 primiparous sisters was 20.2%. The relative risk of preeclampsia in primiparous sisters of probands with preeclampsia compared with primiparous women in the population was 2.6 (95% confidence interval, 1.8 to 3.6). Factors in probands independently associated with a higher risk of preeclampsia in sisters included at least 2+ proteinuria and region of the province. This population-based study, which used unbiased ascertainment and strict diagnostic criteria, demonstrated a significantly higher risk of preeclampsia in sisters of probands with preeclampsia, particularly when probands were defined by severity of preeclampsia and by geographic region.

We investigated the relationship between gestational glucose intolerance and the development of pregnancy-induced hypertension including gestational hypertension (GH) and preeclampsia. Consecutive Japanese women with singleton pregnancies underwent a standard 1h, 50g oral glucose challenge test (GCT) at 24-27 weeks of gestation, followed by a 75g, 2h oral glucose tolerance test (OGTT) if the GCT result exceeded 130mg/dl. Using criteria of the Japan Society of Obstetrics and Gynecology, gestational diabetes mellitus (GDM) was defined by two or more abnormal OGTT values and mild glucose intolerance by one abnormal value. The normal glucose tolerance group included women with GCT results below 130mg/dl or normal OGTT values. GH was defined as blood pressure of at least 140/90mmHg occurring for the first time after mid-pregnancy, without proteinuria. Preeclampsia was determined as GH with proteinuria. Of 2651 consecutive patients, 49 women were found to have GDM, and 139 showed mild glucose intolerance. Sixty patients showed GH, and 58 developed preeclampsia. The frequency of GH in mild glucose intolerance or GDM was 5.8% or 8.2%, respectively, significantly greater than in normal glucose tolerance (P<0.01). Incidence of preeclampsia was not significantly increased in women with mild glucose intolerance or GDM (2.2% or 4.1%, respectively, compared to those with normal glucose tolerance). Japanese women with gestational glucose intolerance therefore have an increased risk of developing GH.

This prospective study was carried out to determine the prevalence of gestational diabetes mellitus (GDM) in Kashmiri women and to assess the effect of various demographic factors. Two thousand pregnant women (divided into groups A and B, being the first and last 1000 consecutive women) attending various antenatal clinics in six districts of Kashmir valley were screened for GDM by 1 h 50 g oral glucose challenge test. Four hundred and fourteen (20.8%) women (216 from group A and 198 from group B) had an abnormal screening test and proceeded to oral glucose tolerance testing. Women from group A had a 3 h 100 gram oral glucose tolerance test (OGTT) and GDM was as classified by Carpenter and Coustan. A 2 h 75 g OGTT was performed on group B subjects and WHO criteria applied for diagnosis of GDM. The overall prevalence of GDM was 3.8% (3.1% in group A versus 4.4% in group B-P-value 0.071). GDM prevalence steadily increased with age (from 1.7% in women below 25 years to 18% in women 35 years or older). GDM occurred more frequently in women who were residing in urban areas, had borne three or more children, had history of abortion(s) or GDM during previous pregnancies, had given birth to a macrosomic baby, or had a family history of diabetes mellitus. Women with obesity, hypertension, osmotic symptoms, proteinuria or hydramnios had a higher prevalence of GDM.

Beside prevention routine antenatal care involves screening examinations for early diagnosis and therapy of pregnancy associated complications. Antenatal care guidelines recommend physical and especially vaginal examination, ultrasonographic evaluation, laboratory examinations, but also urine analysis. The commonly used urine analysis by dipstick can provide information on urinary tract infections, glucosuria and proteinuria. While the estimation of glucosuria has been found to be of no use for the detection of gestational diabetes and therefore is not recommended as a screening method for this disorder, urine analysis by dipstick or culture for bacteriuria or urinary tract infection followed by an antibiotic treatment is able to reduce maternal and neonatal complications. The most important role for urine analysis is the detection of proteinuria by routine dipstick examination and the quantification of proteinuria by 24 hour urin sampling in women with hypertensive disorders in pregnancy, especially in preeclampsia.

Gestational diabetes (GD, characterized by abnormal D-glucose metabolism), intrauterine growth restriction (IUGR, a disease associated with reduced oxygen delivery (hypoxia) to the foetus), and preeclampsia (PE, a pregnancy complication characterized by high blood pressure, proteinuria and increased vascular resistance), induce foetal endothelial dysfunction with implications in adult life and increase the risk of vascular diseases. Synthesis of nitric oxide (NO) and uptake of L-arginine (the NO synthase (NOS) substrate) and adenosine (a vasoactive endogenous nucleoside) by the umbilical vein endothelium is altered in pregnancies with GD, IUGR or PE. Mechanisms underlying these alterations include differential expression of equilibrative nucleoside transporters (ENTs), cationic amino acid transporters (CATs), and NOS. Modulation of ENTs, CATs, and NOS expression and activity in endothelium involves protein kinase C (PKC), mitogen-activated protein kinases p42 and p44 (p42/44(mapk)), calcium, and phosphatidyl inositol 3 kinase (PI3k), among others. Elevated extracellular D-glucose and hypoxia alter human endothelial function. However, information regarding the transcriptional modulation of ENTs, CATs, and NOS is limited. This review focuses on the effect of transcriptional and post-transcriptional regulatory mechanisms involved in the modulation of ENTs and CATs, and NOS expression and activity, and the consequences for foetal endothelial function in GD, IUGR and PE. The available information will contribute to a better understanding of the cell and molecular basis of the altered vascular endothelial function in these pregnancy diseases and will emphasize the key role of this type of epithelium in placental function and the normal foetal development and growth.

The outcome of pregnancy in kidney donors has generally been viewed to be favorable. We determined fetal and maternal outcomes in a large cohort of kidney donors. A total of 2102 women have donated a kidney at our institution; 1589 donors responded to our pregnancy surveys; 1085 reported 3213 pregnancies and 504 reported none. Fetal and maternal outcomes in postdonation pregnancies were comparable to published rates in the general population. Postdonation (vs. predonation) pregnancies were associated with a lower likelihood of full-term deliveries (73.7% vs. 84.6%, p = 0.0004) and a higher likelihood of fetal loss (19.2% vs. 11.3%, p < 0.0001). Postdonation pregnancies were also associated with a higher risk of gestational diabetes (2.7% vs. 0.7%, p = 0.0001), gestational hypertension (5.7% vs. 0.6%, p < 0.0001), proteinuria (4.3% vs. 1.1%, p < 0.0001) and preeclampsia (5.5% vs. 0.8%, p < 0.0001). Women who had both pre- and post-donation pregnancies were also more likely to have these adverse maternal outcomes in their postdonation pregnancies. In this large survey of previous living donors in a single center, fetal and maternal outcomes and pregnancy outcomes after kidney donation were similar to those reported in the general population, but inferior to predonation pregnancy outcomes.

The prevalence of diabetes in pregnant women is increasing, with 4% of deliveries in the United States occurring in women with pregestational or gestational diabetes. The proteinuria of late pregnancy is exaggerated in women with diabetes. However, diabetic women with preserved renal function before pregnancy appear to have little risk of deterioration of kidney function during pregnancy. Women with impaired renal function before pregnancy may be at risk for permanent decline of renal function during pregnancy, although it is unclear whether this represents the effect of pregnancy or the natural history of their diabetic renal disease. Preeclampsia, which is more common in women with diabetes, may be difficult to diagnose in this group of women. From the currently available literature, there appears to be no negative effect of pregnancy on the long-term progression of diabetic renal disease if renal function is normal and marked proteinuria is absent, but in light of recent findings in which preeclampsia appears to be associated with an increased risk of end-stage renal disease, large cohort studies will be necessary before this question can be definitively answered.
