A questionnaire survey and review of the literature show that pregnancy can be well tolerated in most women with renal transplants. Fifty-two per cent of the renal transplant recipients who became pregnant had full-term infants with no serious complications. With therapeutic abortions, excluded, 71% of the 308 pregnancies permitted to continue resulted in full-term infants. Rejection episodes were occasionally a serious problem, occurring in 9% of the pregnancies. Mechanical interference with renal excretion or preventing vaginal delivery occurred in 5.6% of the cases. Hypertension and proteinuria, often existing prior to pregnancy, became frequently increased during pregnancy. Infections not associated with rejection were common but easily controlled in most cases. Prematurity was frequent but related to renal function and the time interval from transplant to conception. The most serious infant complications were related to prematurity. Unknown is the future of these infants and their progeny because of their intrauterine exposure to immunosuppressive drugs.

A total of 99 patients with pre-eclampsia and proteinuria were managed conservatively between 30 and 37 weeks of gestation, based on serial urinary estriol, liquor amnii, and renal function studies. The over-all perinatal wastage was 14 per cent, but was 35 per cent in association with subnormal estriol excretion and oligohydramnios (less than 250 ml.). In severe pre-eclampsia (blood pressure greater than 170/110 mm. Hg with proteinuria greater than 5 Gm. per liter) the incidence of subnormal estriol was 73 per cent and, becuase of this and the associated maternal hazards, conservative treatment had little place. However, in less severe pre-eclampsia with proteinuria early in the third trimester, this prospective study, based on serial placental and renal function tests, showed that frequently the pregnancy could be prolonged and fetal losses due to prematurity avoided. It should be stressed that such conservative treatment should not be continued when there are strong clinical contraindications. Irrespective of the severity of the prior pre-eclampsia, it was unusual for patients to show residual hypertension, proteinuria, or abnormal pyelography at their postnatal examination. Postpartum renal biopsy showed either normal histology or regression of the classical glomerular lesion in 77 per cent of cases.

1. The blood pressures of pregnant patients with proteinuria seem to be no higher than the levels of blood pressure in patients with no proteinuria. The presence of proteinuria and pregnancy in the absence of blood pressure elevation increases perinatal mortality above the values where blood pressure elevation occurs alone. This relationship is most prominent among nulliparous median-age pregnant patients. Even though the number of patients is small, the highest rates occur in the young white nullipara from the sixteenth to twenty-third week of pregnancy. Attempts to compare black and white median-aged nulliparas are meaningless because of the tremendous variability of data. 2. The findings in all cohorts with proteinuria were essentially the same as those in Cohorts I, II and III. Proteinuria of 2+ or greater occurs more frequently in black than in white gravidas. 3. Our observations indicate that perinatal mortality rates in patients with proteinuria are, for the most part, at least twice the rates of patients without proteinuria. 4. The volume of data available is insufficient to determine whether proteinuria influences prematurity rates or mean birth weights. However, our data suggest that some vascular or renal lesion must be affecting perinatal mortality. 5. The small number of patients in the proteinuria study group does not permit meaningful comparisons with the patient group presenting no edema or proteinuria. 6. Adherence to suitable criteria for discovering and measuring proteinuria is necessary to make the diagnosis of preeclampsia. These criteria include careful collection of urine in the clinic or hospital, utilization of acceptable standard testing methods, and the application of uniform principles of medical practice to the overall care of obstetric patients. 7. The data are presented, not interpreted. However, we cannot discount the value of the present data in suggesting the urgent need to restudy more of the current data available. It also seems desirable to initiate another program to investigate a smaller group of patients made up of the same sequential cohorts where it may be possible and more practical to apply strict supervision of statistical design, patient care, personnel, laboratory testing, data recording, data processing and reporting and statistical analysis.

A case-control study on preterm delivery was conducted in Jianan and Jianhan District, Wuhan City in 1988. 130 singleton preterm infants were included with 260 term infants as control. The results showed that the risk factors in prematurity were edema-proteinuria-hypertension syndrome (OR 1.8), maternal diseases in pregnancy (OR 1.6), hyperemesis gravidarum (OR 5.1), vaginal bleeding during pregnancy (OR 2.4), premature rupture of membranes (OR 3.6), low weight gain and low average weight gain per week during pregnancy, psychosocial stress during pregnancy, inadequate prenatal care, maternal stature less than 158 cm (OR 1.7), menarche before age 12 (OR 4.3), multi-gravida (OR 2.1), previous induced abortion (OR 2.1) and passive cigarette smoking during pregnancy. The author suggests that early treatment of complications of pregnancy and forcing prenatal care should be emphasized in order to reduce the incidence of preterm births.

During a 12-year period, 254 cases of eclampsia were managed at this center. Eighty patients (32%) did not have edema, 58 (23%) had "relative hypertension," and 49 (19%) did not have proteinuria at the time of convulsions. Eclampsia developed at less than or equal to 20 weeks in 6 patients and beyond 48 hours post partum in 40 (16%). Convulsions developed in 33 while they were receiving standard doses of magnesium sulfate for preeclampsia during or after birth, and subsequent seizures developed in 36 (14%) after magnesium sulfate therapy was started. There was one maternal death (0.4%) and morbidity was frequent (acute renal failure, 4.7%; pulmonary edema, 4.3%; cardiorespiratory arrest, 3.1%; and aspiration, 2%. The use of multiple drug therapy was associated with significant maternal and neonatal complications. The total perinatal mortality was 11.8%, with the majority of them related to either abruptio placentae or extreme prematurity. These findings emphasize the need for intensive monitoring of women with preeclampsia throughout hospitalization and underscore the importance of maternal stabilization before and during transfer.

Three hundred and ninety-five pregnancies undertaken by 238 women with primary glomerulonephritis between 1962 and 1987 were analysed to record fetal and maternal outcome and identify risk factors for a poor outcome. Of 398 fetuses, 26 per cent were lost (including therapeutic abortions), 24 per cent surviving infants were premature (less than or equal to 36 weeks gestation) and 51 per cent were term. Excluding therapeutic abortions, 20 per cent of fetuses were lost, 15 per cent after 20 weeks gestation. Fifteen per cent of 237 fetuses whose birth weight was recorded were small for gestational age: Deterioration in maternal renal function was seen in 15 per cent of pregnancies and in 5 per cent of women failed to resolve post partum. Only four women had impaired renal function recorded in the first-trimester and two of these were known to have renal impairment before pregnancy. Hypertension was recorded in 52 per cent of pregnancies, developed early (less than or equal to 32 weeks gestation) in 26 per cent and was severe in 18 per cent. Treated hypertension pre-dated 12 per cent of pregnancies and in 7 per cent (included in the overall incidence of hypertension) exacerbation occurred during pregnancy despite continued antihypertensive medication. Forty-four women (18 per cent) who developed de novo hypertension in pregnancy had permanent hypertension postpartum. Increased proteinuria was recorded in 59 per cent of pregnancies and was irreversible in 15 per cent of women. Comparison of pregnancies which occurred before or after renal biopsy revealed a significantly higher fetal loss rate after 20 weeks gestation in those pregnancies undertaken before the diagnosis of renal disease, and a significantly higher incidence of hypertension and increased proteinuria. Impaired renal function, early or severe hypertension or nephrotic range proteinuria was significantly associated with increased fetal loss, prematurity and fewer full-term infants. There was no significant difference in fetal outcome or maternal complications in pregnancy in patients with treated hypertension before pregnancy and those who were normotensive in the first-trimester. The highest incidence of fetal and maternal complications occurred in patients with primary focal and segmental hyalinosis and sclerosis and the lowest in non-IgA diffuse mesangial proliferative glomerulonephritis. The presence of severe vessel lesions on renal biopsy was associated with a significantly higher total fetal loss and fetal loss after 20 weeks gestation.

Twenty-nine hydropic infants were born in the Kandang Kerbau Hospital between 1980 and 1985, during which there were 131,658 deliveries, giving an incidence of 1 in 4,540 total births. Twenty-five of these cases were confirmed to be due to homozygous alpha thalassaemia. No case of fetal hydrops due to Rh isoimmunization was detected. The mean age of the mothers was 28.86 +/- 4.05 years (+/- SD). Eight patients had delivered 1 hydropic baby previously while 1 had a history of 2 babies with hydrops fetalis; 92% of the patients had been followed antenatally while 8% were first seen when they were admitted in labour; 25% of the patients had anaemia, 52% had polyhydramnios, 20% developed hypertension and 64% had bilateral lower limb oedema. None of the patients had concomitant hypertension, generalized oedema and proteinuria. In 4 cases of recurrent hydrops, serial ultrasound scans were performed from early pregnancy but ultrasonic features of hydrops fetalis were only seen from 27 weeks' gestation. Spontaneous labour occurred in 75% of patients at a mean of 32.3 +/- 3.3 weeks (+/- SD). All delivered vaginally and only 1 patient required abdominal decompression. Four patients required Caesarean section, 2 for failure to progress after induction of labour, 1 for major placenta praevia and the fourth for fetal distress; in the last case, diagnosis of hydrops fetalis was only made after delivery of the baby. All the babies in the series died within one hour of delivery. Homozygous alpha thalassaemia is the commonest cause of hydrops fetalis in Singapore and is an invariably fatal condition. It is associated with an increased incidence of maternal anaemia, polyhydramnios and prematurity.

A prospective ultrasound study was undertaken to investigate the prevalence of pleural effusion in patients with moderate or severe pre-eclampsia. The costophrenic angles of 34 consecutive patients were scanned postpartum with a real-time sector scanner. Six patients had pleural effusions. These patients did not have a greater degree of hypertension or proteinuria than the group without pleural effusion but had early severe disease requiring early delivery. The prematurity of these infants resulted in tenfold increase in perinatal death.

Hepatic dysfunction is one of the frequent manifestations of multisystemic involvement in preeclampsia. This study was conducted to establish the impact of liver dysfunction on maternal and neonatal outcome in women with pregnancy-induced hypertension (PIH). The prevalence of liver dysfunction as determined by an elevated serum glutamic oxalacetic transaminase (SGOT) concentration was 21% in a population of 355 patients with PIH. Liver dysfunction was associated with the presence of severe hypertension, proteinuria, a lower platelet count, and renal compromise (elevated blood urea nitrogen, creatinine, and uric acid serum concentrations). Abdominal pain was also associated with an SGOT elevation. Liver dysfunction was associated with intrauterine growth retardation and prematurity. Furthermore, the association with these neonatal complications was independent from the severity of the hypertension and the presence of proteinuria. Thus, we conclude that liver dysfunction is a frequent complication of PIH and that it is an independent risk factor for maternal and perinatal complications.

The clinical course of 168 pregnancies in 91 women with non-IgA diffuse mesangial proliferative glomerulonephritis has been analyzed. Twenty percent (33) of pregnancies resulted in fetal loss, 18% (31) in premature delivery and 62% (105) in a term infant. Maternal renal function declined, reversibly, in 3% (5) of pregnancies and in 48% (80) hypertension developed. In 53% (89) a significant increase in proteinuria occurred in pregnancy. Fetal and maternal complications of pregnancy occurred more frequently in patients with pre-existing hypertension although differences failed to reach statistical significance (p greater than 0.01). The presence of severe vessel lesions on the diagnostic renal biopsy was associated with a significantly higher fetal loss and prematurity rate (p less than 0.0005 and p less than 0.005, respectively).
