During the years 1970-1977, 234 pregnant diabetics were treated in Oslo. A regimen of close metabolic and obstetric control was used. The total perinatal mortality was 4.3%, and 3.1% in 160 patients followed from before week 28. In 74% of patients mean blood glucose (determined 4 times daily) during the last 5-6 weeks of pregnancy was below 6 mmol/1 and in only one patient above 8 mmol/1. There was a low incidence of ketoacidosis (5 patients), pyelonephritis (3 patients), and severe preeclampsia (1 patient), although mild to moderate preeclampsia occurred in 28 patients. Preeclampsia was not associated with foetal loss. Macrosomia was rare. Respiratory distress occurred in 33 infants, in most cases light to moderate. Two foetal deaths were associated with respiratory distress. Progression of retinopathy was frequent, and appearance of or progression of proliferative changes occurred in 15 patients with retinopathy before pregnancy. Loss of visual acuity was rare, and reading vision was not lost by any patients. Induced vaginal delivery has been used in half the deliveries during the last years, whereas Caesarean section was preferred during the first years. Mean duration of pregnancy at delivery has been 260 days, 256 days during the first four years, and 262 days during the last four.

In order to study the complications and therapeutic outcome of twin pregnancies, a retrospective survey was carried out in the University Central Hospital of Oulu. Twin deliveries during 1965-1973 numbered altogether 335, and their relative frequency was 1.7 %. The deliveries took place in the 37.2th gestational week on an average. The mean weights of the infants were 2590 g (A) and 2562 g (B). Perinatal mortality in the total series was 9.3 % (A 9.0 % and B 9.6 %). Pregnancy terminated before the 37th week in 29.2% of the cases. Perinatal mortality in this group was 27.0 %, while the corresponding value in the full-term group was 1.7 %. The perinatal mortality of primigravidas (14.1 %) was about twofold compared with that of the multiparas (7.2 %). Twin pregnancies were complicated by hyperemesis gravidarum, pre-eclampsia, anaemia, pyelonephritis and hepatosis more often than were the single pregnancies. The complications which contributed towards an increase of perinatal mortality included uterine bleeding in early and late pregnancy, hydramnion and superimposed pre-eclampsia. The complications generally associated with twin pregnancies and the increased perinatal mortality involved require that mothers with twin pregnancy, particularly primigravidas, should be subjected to intensified follow-up and treatment.

To investigate the influence of asymptomatic bacteriuria in childhood on subsequent pregnancy, we reviewed the outcome of 139 pregnancies in 88 women who were first identified during a programme of screening schoolgirls for asymptomatic bacteriuria carried out between 1970-1972. Data were analysed for the following groups: 50 pregnancies in 28 women with known renal scars (group 1); 16 pregnancies in 14 women with normal kidneys and reflux (group 2); 73 pregnancies in 46 women with normal urinary tracts (group 3); 139 healthy controls. Women in group 1 had a 3.3-fold increased relative risk of hypertension (p < 0.01) and a 7.6-fold increased risk of pre-eclampsia (p < 0.05) compared to controls, and a higher rate of obstetric interventions, including emergency caesarean section. Women in groups 2 and 3 appeared to carry a slightly increased risk of hypertension during the last trimester (RR = 1.8) but there were no significant differences in this or the incidence of pre-eclampsia or mode of delivery. Bacteriuria was more prevalent in all index groups compared to controls (37 per cent vs. 8 per cent, p < 0.01) and included four cases of acute pyelonephritis in in the study group. Fetal outcome was satisfactory in all cases. These results suggest that women with renal scars are at risk of hypertension and pre-eclampsia during pregnancy but that modern obstetric care minimizes these risks.

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.

A radionuclide method with quickly disintegrating 99MTC labelled human albumin and DTPA in a volume of 0.3-0.5 ml and activity of 37 mVk with two consecutive examinations of central and renal hemodynamics was used in 91 pregnant women with preeclampsia and pyelonephritis. Marked hypovolemia was found in all groups of investigated women with preeclampsia with the exception of the group of women with pyelonephritis. There was also difference in arterial pressure in women with preeclampsia I degree and pyelonephritis, which was statistically significant with advancement of gravity and duration of the disease. The investigation of the functional state of kidneys and blood flow showed a tendency to slowing both in the arterial and venous circulation in women with pre-eclampsia of pregnancy. In the pregnant women of this group and the women with pyelonephritis there was asymmetry in the curves of the blood flow as well as in the temporary indices of renal filtration, which were increases two-folds in comparison with the normal values. They were mostly manifested on the side of the involvement in women with pyelonephritis. Irradiation loading was 0.212 mZv of both examinations and was ten times less than that of x-ray pelvimetry.

Asymptomatic bacteriuria in pregnant women has been linked to an increased incidence of pyelonephritis, preeclampsia, hypertension, intrauterine growth retardation and premature delivery. Pyelonephritis and cystitis require different antibiotics and dosages in pregnant patients. Renal calculi can be difficult to detect during pregnancy. Women with preexisting renal disease usually do well during pregnancy if renal function is preserved and hypertension is not present.

The outcome of 52 pregnancies in 34 women who had had bacteriuria in childhood was compared with that of normal control pregnancies. The prevalence of bacteriuria at the first antenatal visit was significantly higher (p less than 0.001) in previously bacteriuric women (35%) than in controls (5%), and acute pyelonephritis developed in 10% compared with 4% of controls. Pre-eclampsia (arterial pressure above 140/90 mm Hg with proteinuria above ++) developed in 4 of 12 previously bacteriuric women known to have renal scarring (5 of 16 pregnancies), in only 1 of 22 previously bacteriuric women without scars (1 of 36 pregnancies), and in 1 of 52 controls (p less than 0.001). Women with renal scars were also more likely to undergo induction of labour (44% of pregnancies) and operative delivery (57% of pregnancies) than previously bacteriuric mothers without scars (17%, 22%) or control mothers (16%, 20%). The infants of previously bacteriuric mothers were not significantly smaller than those of healthy control mothers, but Apgar scores were lower among offspring of previously bacteriuric mothers with scarred or normal kidneys (p less than 0.001). Fetal outcome was, however, satisfactory in all cases.

Acute renal failure is a most challenging clinical problem when it occurs in pregnancy. It requires an understanding of the normal physiology of the kidney in pregnancy and the natural history of different underlying renal diseases when pregnancy occurs. Because patients with chronic renal disease may present with worsening proteinuria, hypertension, and renal function, these disorders must be excluded from those conditions that cause acute deterioration of renal failure in otherwise normal women during pregnancy. As in all patients who develop acute renal failure, prerenal and obstructive causes must be excluded. Particularly important causes of prerenal azotemia in pregnancy include hyperemesis gravidarum and uterine hemorrhage, especially if it is unsuspected as in abruptio placentae. Infectious causes of acute renal failure in the pregnant woman include acute pyelonephritis and septic abortion. The clinical presentation of both these conditions should be apparent, and appropriate diagnosis and treatment can then be promptly instituted. Renal cortical necrosis is another cause of renal failure that occurs more frequently in pregnancy, and it must be differentiated from the many causes of acute tubular necrosis that may be associated with pregnancy. Those conditions that cause renal failure unique to pregnancy must always be considered when renal function deteriorates in the last trimester or the postpartum period. Severe preeclampsia, acute fatty liver of pregnancy, and idiopathic postpartum acute renal failure may all present similar complications, but the approach to each of these clinical disorders must be individualized. By understanding the causes of renal functional deterioration in pregnancy, a logical differential diagnosis can be established, allowing appropriate therapeutic decisions to preserve both maternal and fetal well-being.

Acute renal failure has become a very rare complication of pregnancy. This results from the virtual disappearance of septic abortion ARF and from the improvement of prenatal care, including the prevention of volume contraction which is mainly due to uterine haemorrhage, early diagnosis, and treatment of other classic maternal complications such as pre-eclampsia and acute pyelonephritis. The incidence of BRCN has also been declining during the last decade. Acute fatty liver, a potentially fatal disease, is often complicated by ARF. Early recognition of this disorder with prompt termination of pregnancy and intensive supportive therapy can reduce fetal and maternal mortality rate. The syndrome of idiopathic postpartum renal failure is also associated with a high morbidity and mortality. Beyond supportive treatment including haemo- or peritoneal dialysis, the use of potent antihypertensive drugs to control blood pressure and blood transfusion if necessary, specific therapy as plasma infusion, plasma exchange and antiplatelet drugs may be of value. Both peritoneal dialysis and haemodialysis may be used in gravidas with ARF. Early 'prophylactic' dialysis should be applied to pregnant women. Careful monitoring of fluid balance and anticoagulation is necessary during dialysis.

Urinary excretion of the low molecular weight protein beta 2-microglobulin and tubular enzymes--alanine aminopeptidase (AAP), gamma-glutamyl transpeptidase (gamma-GT) and alkaline phosphatase (AP)--are very sensitive parameters for proximal tubular lesions. In patients with preeclampsia the renal excretion of beta 2-microglobulin allows to differentiate between a primary preeclampsia and a preeclampsia superimposed upon chronic pyelonephritis. In the first group the increase is 3- to 4-fold and in the second group up to 300-fold. In patients with kidney transplantation the urinary excretion of beta 2-microglobulin, AAP, gamma-GT and AP are several times higher than in normals. In case of a rejection episode a further increase of these proteins occur in more than 80% several days before clinical symptoms are present. The application of analgetics (paracetamol, acetylsalicylic acid) in healthy individuals in therapeutical dosages on 3 consecutive days does not show any tubular alteration by the measurement of urinary beta 2-microglobulin. Aminoglycosides (tobramycin, UK 18,892) lead to a cumulative increase of the renal excretion of beta 2-microglobulin and AAP while cephalosporins induce an increase of total proteins in the final urine under the same conditions.
