Toxicosis was induced in pregnant Holstein-Friesian heifers by giving polybrominated biphenyls a in gelatin capsules at the rate of 25 g/day. Initially, this dosage was approximately 67 mg/kg of body weight. Clinical signs were anorexia, excessive lacrimation and salivation, diarrhea, emaciation, dehydration, depression, and abortion. Fever was not evident during the experiment. Values for serum glutamic-oxalacetic transaminase, lactic dehydrogenase, blood urea nitrogen, and bilirubin were increased. Changes in packed cell volume, hemoglobin content, total erythrocyte and leukocyte counts, and differential leukocyte counts were minimal and reflected dehydration and secondary infection. The principal urine changes were decreased specific gravity and moderate proteinuria. Gross necropsy findings included dehydration; subcutaneous emphysema and hemorrhage; atrophy of the thymus; fetal death with concomitant necrosis of cotyledons; kidneys that were enlarged, pale tan to gray; thickened wall of the gallbladder; inspissated bile; edema of abomasal folds; mucoid enteritis; linear hemorrhage and edema of the rectal mucosa; and secondary pneumonia. Microscopic changes were most marked in the kidneys, gallbladder, and eyelid. In the kidney, the principal changes were extreme dilatation of collecting ducts and convoluted tubules, with epithelial degenerative changes of cloudy swelling, hydropic degeneration, and separation from the basement membrane. Common changes in the gallbladder were moderate to marked hyperplasia and cystic dilatation of the mucous glands in the lamina propria. The changes in the eyelids were characterized by hyperkeratosis, with accumulations of keratin in hair follicles of the epidermis and squamous metaplasia with keratin cysts in the tarsal glands. Clinical signs and lesions of toxicosis did not develop in heifers given the polybrominated biphenyls at the rate of 0.25 mg and 250 mg/day for 60 days. Initially these rates were approximately 0.00065 mg/kg and 0.65 mg/kg of body weight, respectively.

Toxicosis was induced in pregnant heifers by feeding 25,000 mg/head/day of FireMaster BP-6, a commercial blend of polybrominated biphenyls (PBB). The PBB feeding decreased dry matter intake approximately 50% by 4 days exposure. Emaciated animals became anorexic a few days prior to death at 33 to 66 days. Weight losses of heifers average 80 kg. Other clinical signs observed were dehydration, diarrhea, excessive salivation and lacrimation, fetal death, abortion, and general depression as evidenced by depressed heart and respiratory rates. Clinical signs were apparent after 10 days exposure and progressively intensified along with loss of condition until death. Clinicopathologic changes included significantly increased serum glutamic-oxaloacetic transaminase and decreased serum calcium by 30 days exposure. Lactate dehydrogenase, urea nitrogen, and bilirubin were elevated, and serum albumin decreased by 36 to 40 days. Principal urine changes were decreased specific gravity and moderate proteinuria. Pregnant heifers fed 0.25 or 250 mg/head/day for 60 days and nonpregnant heifers fed 250 mg/head/day for 180 days displayed neither clinical signs nor clinicopathologic changes indicating adverse effects from PBB exposure. Post-exposure, all heifers exposed to PBB for 60 days calved normally with zero calf mortality and were successfully rebred. Milk production was not different from control animals. Birth weights of calves from dams exposed to 250 mg PBB/head/day were significantly greater than calves of dams exposed to 0 mg or 0.25 mg/head/day. PBB exposure of dams produced no detrimental effects on calves as indicated by clinical signs, clinicopathologic changes, or performance.

A case of acute renal failure subsequent to hypertonic saline abortion is reported. A 26-year-old woman who had received a kidney allograft 7 months earlier was admitted to hospital for midtrimester abortion. Shortly after saline installation she developed a fever. Fetus and placenta were passed the following day but her temperature continued to rise. Urine output rose sharply; urinalysis showed a specific gravity of 1.005, 1+ proteinuria, moderate hemoglobinuria, 5-10 leukocytes, and a few granular casts. Her medications were 125 mg/day azathioprine, 25 mg/day prednisone, aluminum hydroxide gel, calcium carbonate, dihydrotachysterol and multivitamins. Her condition improved to the point of discharge 1 week postabortion. It is hypothesized that a combination of hemoglobinuria and mild intravascular coagulation contributed to the condition. Caution is advised when considering saline abortion for patients with transplanted kidneys.

It has long been known or suspected that phenytoin and probably phenobarbitone prescribed in pregnancy may lead to fetal malformations. The use of troxidone for epileptic women during pregnancy was reported in 1970 to lead to malformations. Over 50 instances of pregnancy in women taking troxidone have since been reported. In 8 of these the drug was used alone. 13 pregnancies resulted in abortion and 33 of the 40 survivors had a minor congenital anomaly, leading to death in 14. Complex congenital heart lesions with patent ductus, septal defects and aortic hypoplasia were apparent in half the survivors. Malformed or low-set ears were seen in nearly half the cases, palatal deformities were less common and evidence intrauterine growth retardation was frequently present. A 29-year-old mother taking troxidon and carbamazepine, and with a history of hypertension and proteinuria dating back to adolescence, delivered her first child prematurely. The child was small, showed deformed ears, displayed feeding problems and was found to be in cardiac failure with a systolic murmur and absent femoral pulses. Postnatal growth was retarded and after further cyanotic attacks a cardiac catheter study was performed. This showed a hypoplastic aortic arch with an anomolous origin of the left subclavian artery and patent ductus arteriosus, findings similar to those previously reported in neonates following maternal use of troxidone.

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.

The authors report a case of lupus showed in labour by the presence of generalised convulsions and coma after the crisis. This was followed by labile transitory hypertension, by massive proteinuria which cleared in 15 days, by major hyperthermia (higher than 39.5 degrees) and transitory agranulocytosis. The infant had a purely biological neonatal lupus. Pregnancy in a lupus patient has two risks: the mother's relapses of lupus, it is usual that renal failure is the worst of the prognostic features, but in this patient cerebral complications were much more serious. In the fetus there is a risk of spontaneous abortion linked to the anticardiolipin antibody level, and the risk of disease in the heart due to the anti-SSA (or anti-Ro) factor giving rise to congenital auriculo-ventricular blocks. The therapeutic possibilities are classically treated with immunosuppressants, mainly corticoids, which is added to low doses of aspirin. Plasmaphoresis and immunoglobulin treatments are being tried out.

The impacts of IgA nephropathy and pregnancy on each other were evaluated in 118 women who conceived 168 times between 1970 and 1988. Rates of spontaneous abortion, normal delivery, live birth and perinatal death were 9, 66, 87 and 4%, respectively. Infants born to women with glomerular filtration rates (GFR) lower than 70 ml/min prior to conception had a higher perinatal mortality rate (14% vs. 3%, P less than 0.001). This was also true if pre-pregnancy blood pressures were consistently higher than 140/90 mm Hg (33% vs. 1%, P less than 0.001). These were the figures for the whole 18 year period, but stratification of the data revealed that most adverse results occurred in the 1970's, during which the perinatal death rate was 9%, while it was 0% in the 1980's. Eighty-five women were followed for three years or more. At final follow-up, the rates of decrease in GFR, and increases in blood pressure and proteinuria were 19, 11 and 7%, respectively. In most patients the natural history of IgA nephropathy was similar to that of women who had not experienced pregnancy, but there were five instances where gestation seemed to accelerate functional loss, with rapid development of end-stage or near end-stage renal failure. Most women with IgA nephropathy should anticipate few problems with pregnancy, if they are normotensive and their preconception GFR exceeds 70 ml/min. The gestation in such instances should have little influence on the natural history of their nephropathy.

In an attempt to clarify the influence of pregnancy on the natural course of the chronic glomerulonephritis with impaired renal function (glomerular filtration rate: GFR less than or equal to 70 ml/min), the courses of 14 pregnancies occurring in 10 patients (seven with IgA nephropathy, one with membranoproliferative glomerulonephritis, one with membranous nephropathy and one with hereditary nephropathy) were studied. In 8 patients GFR measured before pregnancies ranged from 46 to 70 ml/min and in the other two creatinine clearance estimated in the first trimester of pregnancies was 62 and 49 ml/min, respectively. The pregnancies resulted in 10 live births, one spontaneous abortion, one artificial abortion and 2 neonatal deaths. In 2 out of 10 live births fetal weight was less than 2500 g. In 3 of 11 pregnancies there was neither increase in urinary protein nor elevation of blood pressure during pregnancies, while seven (64%) had increased proteinuria during the third trimester, and 4 of them were also complicated with hypertension. In 6 of 10 patients, there was no decrease in GFR during pregnancies. In three patients GFR was decreased from 70 to 36 ml/min, 70 to 58 ml/min and 62 to 48 ml/min, respectively. However, these reductions were considered to go with the natural course of respective patients because the reduction slopes were almost the same or rather mild in comparison with those estimated before or after pregnancies. The other patient also had a transient increase in serum creatinine level during two pregnancies, but the reciprocals of serum creatinine concentration before and after the pregnanciesdeclined linearly with time. These data suggest that pregnancy might have little influence on the natural course of the chronic glomerulonephritis even if complicated with renal functional impairment defined as GFR of 70 ml/min or less.

Between 1975 and 1988 authors encountered 44 pregnancies in 26 women who had had chronic renal disease and unimpaired renal function before the conception. Complications during pregnancy and the outcome of pregnancy were studied. There were 5 spontaneous abortions between the 11th and 20th weeks of gestation, 1 therapeutic abortion, 3 still births at weeks 28, 32 and 33, 6 neonatal deaths at age of 26 to 35 weeks, 11 preterm newborns, 35 live births, 9 infants with intrauterine growth retardation including 4 preterm newborns and 1 fetal malformation and 2 cases with premature rupture of the fetal membranes. The pregnancies were complicated with anaemia in 23 cases, with urinary tract infection in 19, with hypertension in 16, with proteinuria in 12 and with edema in 11 cases. Increase in the serum creatinine value during pregnancy was found in 6 cases. These data indicate that the pregnancy in patients with chronic renal disease who had normal renal function before the planned conception, is accompanied with increased risk for both the mother and child.

We analysed the outcome of pregnancy in patients with pre-existing lupus nephritis, seen in a tertiary referral centre for nephrology. Fifty-three pregnancies in 25 patients who already had clinical and histological evidence of lupus nephritis were recorded between January 1970 and June 1989, and data were analysed retrospectively. All 53 pregnancies occurred in patients with more or less stable disease, while three pregnancies during which lupus first presented were excluded. Six pregnancies were ended by therapeutic abortions (four for social reasons), and in eight spontaneous abortion occurred. Thus, 39 deliveries occurred, 28 at 36 weeks or more, while 11 were delivered prematurely, of which one was a stillbirth. After allowance was made for therapeutic abortions, the fetal loss rate (9/47) was 19%. Seventeen Caesarian sections were performed in the 39 completed pregnancies (44%), 11 as emergencies. Although the overall fetal loss, incidence of premature births and Caesarian section rate were all higher than expected for a population of normal women, neither initial histology, treated hypertension, the presence of proteinuria or a nephrotic syndrome showed statistically significant relationships with the outcome of completed pregnancies. In no case was maternal renal function affected irreversibly, although proteinuria increased substantially during pregnancy in six patients, and creatinine clearance fell during pregnancy, also in six patients. No 'flares' in systemic disease were seen, but all patients save five were treated with a brief period of high-dose oral corticosteroids or intravenous methylprednisolone in the postpartum period. No case of neonatal lupus or congenital heart block was observed.(ABSTRACT TRUNCATED AT 250 WORDS)
