Abstract
The number of pregnancies in women with pregestational diabetes has been steadily increasing worldwide. These pregnancies are associated with an increased risk of a variety of complications, including miscarriages, congenital malformations, macrosomia, fetal growth restriction, preeclampsia, preterm delivery and stillbirth. In pregnant women with diabetic nephropathy it is important to evaluate both the effect of pregnancy on kidney function and the effect of kidney disease on pregnancy outcomes. Pregnant women with normal renal function and microalbuminuria have a low risk of loss of kidney function during pregnancy, while women with GFR < 60 ml/min and/or proteinuria ≥ 3 g/24 h at the beginning of pregnancy are at risk of permanent kidney damage. The risk of fetal and maternal complications is associated with the severity of chronic kidney disease and glycemic control. Advances in prenatal care have improved fetal and maternal outcomes and preconception counseling has become key for a successful pregnancy in all women with diabetes and especially in those with diabetes and chronic kidney disease.

Abstract
Long-standing hyperglycemia frequently leads to vasculopathy. Microvascular disease is characterized by retinopathy and nephropathy, while macrovascular involvement can affect coronary arteries. Diabetic autonomic neuropathy, when present, is generally associated with retinal and/or renal involvement. Early identification of these diabetic complications allows appropriate counseling and early treatment. Among women with diabetic vasculopathy, nephropathy, chronic hypertension, preeclampsia, preterm delivery, and fetal growth restriction are frequently observed. Furthermore, women with impaired renal function in early pregnancy have increased risk of long-term deterioration of glomerular filtration rate. Proliferative retinopathy can progress during pregnancy and 1 year after delivery, but long-term effects are not likely to occur. When coronary artery disease or gastroparesis diabeticorum are present, excessive maternal and fetal morbidity is observed. When modern management is synchronized with early medical care, favorable maternal and perinatal outcomes can be expected.

Abstract
INTRODUCTION Pregestational and gestational diabetes mellitus (PGDM; GDM) are significant health concerns because they are associated with an increased rate of malformations and maternal health complications. METHODS We reviewed the data that help us to understand the effects of diabetes in pregnancy. RESULTS Diabetic embryopathy can affect any developing organ system, but cardiovascular and neural tube defects are among the most frequent anomalies. Other complications include preeclampsia, preterm delivery, fetal growth abnormalities, and perinatal mortality. Neurodevelopmental studies on offspring of mothers with diabetes demonstrated increased rate of Gross and Fine motor abnormalities, of Attention Deficit Hyperactivity Disorder, learning difficulties, and possibly also Autism Spectrum Disorder. The mechanisms underlying the effects of maternal hyperglycemia on the developing fetus may involve increased oxidative stress, hypoxia, apoptosis, and epigenetic changes. Evidence for epigenetic changes are the following: not all progeny are affected and not to the same extent; maternal diet may influence pregnancy outcomes; and maternal diabetes alters embryonic transcriptional profiles and increases the variation between transcriptomic profiles as a result of altered gene regulation. Research in animal models has revealed that maternal hyperglycemia is a teratogen, and has helped uncover potential therapeutic targets which, when blocked, can mitigate or ameliorate the negative effects of diabetes on the developing fetus. CONCLUSIONS Tight metabolic control, surveillance, and labor management remain the cornerstone of care for pregnant women with diabetes, but advances in the field indicate that new treatments to protect the mother and baby are not far from becoming clinical realities.

Abstract
Controversy exists regarding the effect of pregnancy on the development and course of diabetic nephropathy. This study followed 43 pregnant women with previous diabetes mellitus, 32 without nephropathy (Group I) and 11 with nephropathy (Group II). Urinary albumin excretion (UAE), serum creatinine (Cr) and creatinine clearance (CCr) in the pre-pregnancy (Pre-P), first trimester (1T), third trimester (3T) and 1 year postpartum (PP) were evaluated. In both groups there were an increase in 3T compared to Pre-P of CCr (137 vs. 98 ml/min and 110 vs. 81 ml/min, p=0.0001, respectively) and UAE (7.78 vs. 3.15 mg/24 h and 592 vs. 119 mg/24 h, p=0.0001, respectively). Increase of Cr in the PP compared to 1T in Group II (0.88 vs. 0.70 mg/dL, p=0.031) was observed. There were no difference in UAE, CCr and Cr in the PP when compared to pre-P as well variance over time between groups. Group II showed higher prevalence of chronic hypertension (72.7 vs. 21.9%, p=0.004), preeclampsia (63.6 vs. 6.3%, p=0.0003) and lower gestational age at birth (36 vs. 38 weeks, p=0.003). We conclude that pregnancy was not associated with development and progression of diabetic nephropathy in women with or without mild renal dysfunction. The presence of diabetic nephropathy was associated with increased risk of perinatal complications.

Abstract
Pregestational diabetes is a common complication of pregnancy that can be associated with severe maternal and fetal morbidity. In addition, some women could have progression of diabetic complications secondary to pregnancy. Preconception care can significantly reduce pregnancy complications with a dramatic impact on the diabetic mother and her infant. For those women whose condition could be hastened by conception education, better understanding and an improved decision should be available to them and their families. Because unplanned pregnancy is common among diabetic women, they should be counseled early for the importance of preconception care in the progression of this disease.

Abstract
Chronic kidney disease complicates an increasing number of pregnancies, and at least 4% of childbearing-aged women are afflicted by this condition. Although diabetic nephropathy is the most common type of chronic kidney disease found in pregnant women, a variety of other primary and systemic kidney diseases also commonly occur. In the setting of mild maternal primary chronic kidney disease (serum creatinine <1.3 mg/dL) without poorly controlled hypertension, most pregnancies result in live births and maternal kidney function is unaffected. In cases of more moderate and severe maternal primary chronic kidney disease, the incidence of fetal prematurity, low birth weight, and death increase substantially, and the risk of accelerated irreversible decline in maternal kidney function, proteinuria, and hypertensive complications rise dramatically. In addition to kidney function, maternal hypertension and proteinuria portend negative outcomes and are important factors to consider when risk stratifying for fetal and maternal complications. In the setting of diabetic nephropathy and lupus nephropathy, other systemic disease features such as disease activity, the presence of antiphospholipid antibodies, and glycemic control play important roles in determining pregnancy outcomes. Concomitant with advances in obstetrical management and kidney disease treatments, it appears that the historically dismal maternal and fetal outcomes have greatly improved.

Abstract
OBJECTIVES The first objective was to assess the association of renal function with maternal and fetal pregnancy outcome in women with diabetic nephropathy. The second objective was to examine the feasibility of a multicenter surveillance program to determine the rates of maternal and fetal pregnancy complications in women with diabetic nephropathy, and to study the effect of pregnancy on the natural history of diabetic renal disease. METHODS In order to address the first objective, we analyzed data from women with type 1 diabetes and nephropathy enrolled in the Diabetes in Pregnancy Program at our institution. Women were assigned to one of three groups according to enrolment serum creatinine concentration: < or = 1.0 mg/dl, > 1.0 to 1.5 mg/dl and > 1.5 mg/dl. A pilot surveillance program at six centers included women experiencing pregnancy complicated by diabetic nephropathy. In both studies, medical and obstetric history, and maternal and neonatal outcomes, were recorded. Statistical analysis included chi2, logistic regression and analysis of variance. RESULTS There were 72 pregnancies in 58 women with diabetic nephropathy who enrolled in the pregnancy program. High serum creatinine concentration at enrolment was associated with delivery before 32 weeks' gestation, very low birth weight and increased incidence of neonatal hypoglycemia, independent of quantity of total urinary protein excretion and glycemic control in any trimester. To date, pilot surveillance data have been obtained from six centers on 16 women. Serum creatinine concentrations ranged from 0.4 to 1.1 mg/dl and creatinine clearance from 32 to 317 m/min. Gestational age at delivery ranged from 22 to 39 weeks. CONCLUSIONS High serum creatinine concentration at enrolment is a risk factor for adverse maternal and neonatal outcome, independent of quantity of total urinary protein excretion and glycemic control during any trimester. A multicenter surveillance program is needed, in order to study less frequent maternal and neonatal outcomes as well as the long-term effects of pregnancy on the natural course of diabetic renal disease.

Abstract
The objective of the study was to evaluate differences in the perinatal complications and in the 3-year follow up of infants of diabetic mothers with and without diabetic nephropathy stage IV. We compared the fetal and maternal complications and the early postpartal development until 3 years after delivery in 10 children of nephropathic diabetic mothers and 30 children of diabetic mothers without nephropathy. The mean (+/-SD) birthweight of the infants of nephropathic women was 2,250 +/- 496 g versus 3,544 +/- 435 g in the women without nephoropathy (p < 0.01). Births were premature in six pregnancies (60%) of the nephrotic women but in none of the women without nephropathy (p < 0.01). Three infants (30%) of the women with nephropathy showed respiratory distress syndrome in contrast to two babies (6%) of the women without nephropathy. Pre-eclampsia or eclampsia occurred in 6 (60%) pregnant women with and in two women (6%) without diabetic nephropathy (p < 0.01). Nephrotic syndrome was observed in 7 nephrotic women (70%) in contrast to none women without nephropathy. Three years postpartum, six of the children (60%) of nephropathic women had a body weight < the 50th percentile but none of the children of the women without nephropathy did so (p < 0.01). In addition, the children of nephropathic mothers started to speak significantly later (15 +/- 3 versus 12 +/- 13 months postpartum, p < 0.05) and had infectious diseases more commonly (60% versus 6%, p < 0.01) than the children of women without nephropathy. It can be concluded that in pregnancies of diabetic women the birth weights of the infants are significantly smaller and the fetal as well as maternal complication-rates significantly higher than in those of women without nephropathy. Also 3 years after delivery, the body weight of the children of nephropathic diabetic women is significantly lower than that of children of diabetic women without nephropathy. Additionally, children of nephropathic women are retarded in terms of linguistic development and their resistance to infections is reduced.

Abstract
Many women with diabetes develop complications of their chronic disease that may have a tremendous impact on their quality of life and their ultimate prognosis. Because Type 1 diabetes often begins at a very early age, it is quite common for women in their child-bearing years to be affected by these complications. As described in this article, diabetic complications and pregnancy may significantly affect each other, but it is not always easy to predict the course of either and to counsel these patients accordingly. Nevertheless, it appears that only in rare occasions should women with diabetes be advised against pregnancy, and that in most situations, with careful and knowledgeable management, a favorable outcome of pregnancy can be expected both for the mother and her infant.

Abstract
Nephropathy is a complication of diabetes mellitus that can affect women in their reproductive years. This article reviews the effects on treatment on the main factors associated with short- and long-term complications in pregnant women with diabetic nephropathy. Tight glycemic control, adequate treatment of elevated blood pressure, and renal function in early pregnancy are the most significant predictors of maternal and perinatal outcomes. Contemporary methods of perinatal care and adequate treatment of blood pressure allow fetal survival rates of 95%. Furthermore, pregnancy per se does not appear to worsen the natural progression to end-stage renal disease for most women with renal insufficiency. However, patients with moderate to severe renal impairment may experience acceleration of renal disease.

Abstract
The preconception and intrapregnancy parameters that are relevant to outcome in women with insulin dependent diabetes mellitus (IDDM) and diabetic nephropathy remain controversial. We analyzed the types and frequencies of maternal and neonatal complications in 24 IDDM patients with diabetic nephropathy (24 pregnancies), all with preserved to mildly impaired renal function. All patients received treatment with captopril for at least six months prior to planned pregnancy and were maintained under strict glycemic control from at least three months before pregnancy to delivery. A successful pregnancy outcome (live, healthy infant without severe handicaps two years after delivery) was observed in 87.5% of the patients. Preexisting hypertension was the only parameter found to be significantly predictive of an unsuccessful outcome (p = 0.0004). We conclude that in patients with IDDM complicated by diabetic nephropathy, pre-pregnancy captopril treatment combined with strict glycemic control offers a prolonged protective effect against possible renal deterioration and probably improves pregnancy outcome.

Abstract
OBJECTIVE This study was designed to determine whether pregnancy and increasing parity in women with insulin-dependent diabetes mellitus (1) increases the risk for diabetic nephropathy and (2) accelerates the progression of diabetic nephropathy. STUDY DESIGN The study included women with insulin-dependent diabetes mellitus who enrolled in our diabetes-in-pregnancy trial with a pregnancy that continued beyond 20 weeks' gestation and who were delivered between 1978 and December 31, 1991, to allow for a minimum of 3 years' follow-up. Pregnancy and follow-up information was obtained from the medical records and from our computerized database. For patients followed up elsewhere, information was obtained from their current physicians. Life-table analysis was used to determine (1) the risk for nephropathy developing de novo as a function of duration of disease and the association of this risk with parity and (2) the risk of renal failure developing in women with preexisting nephropathy and its association with parity. RESULTS The study population included 182 pregnant women with insulin-dependent diabetes mellitus: 46 with overt nephropathy (group F) and 136 without nephropathy (group NF). Pregnancy and increasing parity did not increase the overall risk for nephropathy (44% after 27 years of diabetes). In group NF 10% had nephropathy within 10.1 +/- 4.2 years of the pregnancy. Proteinuria appearing during pregnancy and glycemic control during pregnancy were significantly associated with the subsequent development of nephropathy. In group F 26% had end-stage renal disease after a median period of 6 years from the pregnancy. Pregnancy or increasing parity did not increase the risk for renal failure in women with nephropathy. CONCLUSIONS Our data support the premise that pregnancy in women with insulin-dependent diabetes mellitus does not increase the risk of subsequent nephropathy and does not accelerate progression of renal disease in women with preexisting nephropathy.

Abstract
Knowledge of the pathogenic mechanisms of diabetic nephropathy (by which hyperglycemia, hyperfiltration, and hypertension cause the gradual development of microproteinuria, mesangial expansion, and eventual glomerular closure) provides the basis for effective treatment. Intensified glycemic control and antihypertensive therapy that is safe for the fetus are crucial for success during pregnancy. Considered outcome measures include perinatal survival, size at birth, child development, and long-term maternal renal function.

Abstract
Since the metabolic changes in normal pregnancy are diabetogenic, pregnancy imposes a severe stress on the metabolic milieu of diabetic patients. Moreover, many patients with long-standing diabetes have vascular complications, including retinopathy, renal insufficiency, nephrotic syndrome and hypertension, all representing separate risk factors for optimal fetal development. Recent experience has suggested that maternal hyperglycaemia, and associated fetal hyperinsulinaemia, may represent an important factor in the development of fetal complications. During the past two to three decades the incidence of perinatal deaths in all categories of diabetics has been reduced to a level that approaches the rate in healthy gravidas when severe congenital anomalies are excluded. Fetal and neonatal morbidity have also been reduced, although rates of congenital anomalies, hydramnios and respiratory distress syndrome remain high. Although the morbidity associated with oedema formation and hypertension is elevated, with meticulous management of patients with diabetic nephropathy, especially in the absence of severe renal insufficiency and/or severe hypertension, pregnancy performance and outcome can be similar to that of other insulin-dependent diabetic patients.
