Abstract
CONTEXT Prenatal treatment with dexamethasone (DEX) has been used to prevent virilization in females at risk of congenital adrenal hyperplasia (CAH). Both affected and unaffected girls, as well boys, are treated until the genotype and sex of the fetus is known (gestational weeks 10-12). After that, only affected girls are treated until term. Exposure to a high synthetic glucocorticoid dosage may alter the developmental trajectory of the brain, with alterations in resting-state functional connectivity of the brain at adult age. OBJECTIVE To investigate resting-state functional connectivity in subjects at risk of having CAH, exposed to DEX treatment during the first trimester of fetal life, both in the whole brain and in 3 regions of interest (amygdala, hippocampus, and superior frontal gyrus). DESIGN, SETTING, AND PARTICIPANTS Eighteen participants (8 females) at risk of having CAH, exposed to DEX treatment, and 38 controls (24 females), age range 16 to 26 years, from a single research institute, underwent functional magnetic resonance imaging of the brain during rest. We used 2 different approaches: an exploratory whole-brain analysis and seed-based analysis. For seed-based analysis, we chose 3 different brain regions (amygdala, hippocampus, and superior frontal gyrus) based on our previous findings and literature evidence. RESULTS We did not observe any differences in functional connectivity during rest, either in the whole brain nor in seed-based connectivity analyses at this adolescent and young adult age. CONCLUSIONS Our results are reassuring; however, future studies on larger samples and with more sensitive methodologies are needed to confirm these findings.

Abstract
CONTEXT The clinical use of dexamethasone (DEX) prenatally to reduce virilization of external genitalia in female fetuses with congenital adrenal hyperplasia (CAH) is efficient but still controversial. It remains challenging to prevent the excessive exposure of DEX in unborn healthy babies during the first trimester of pregnancy. OBJECTIVE Since endogenous glucocorticoids contribute to the maintenance of blood pressure (BP) and since events during fetal life may program the fetus and affect future metabolic health, the aim of this study was to analyze ambulatory BP measurements in CAH-unaffected children and adults that were prenatally exposed to DEX treatment. METHODS Ambulatory BP measurements were analyzed in 33 (16 female) DEX-treated participants aged 5.1 to 26.3 years (19 participants aged ≤ 18 years) and in 54 (28 female) age- and sex-matched apparently healthy controls aged 5.5 to 25.3 years (27 participants aged ≤ 18 years) with ambulatory normotension. RESULTS Participants' age, height, weight, and body mass index were similar between the DEX-treated group and the control group. Heart rate, 24-hour BP, pulse pressure, and nighttime dipping did not statistically significantly differ between DEX-treated participants and controls. CONCLUSION Our study suggests that prenatal DEX treatment in CAH-unaffected children and adults does not appear to adversely affect ambulatory BP later in life. Our observations need to be confirmed in larger studies.

Abstract
CONTEXT Prenatal treatment of human disease is rare. Dexamethasone (DEX) is used in pregnancies at risk for congenital adrenal hyperplasia (CAH) to prevent virilization in an affected female fetus. The safety and long-term consequences of prenatal DEX exposure on the brain are largely unknown. OBJECTIVE We investigate whether first-trimester prenatal DEX treatment is associated with alterations in brain structure at adult age, and if these alterations are associated with DNA methylation, mood, and cognitive abilities. DESIGN, SETTING, AND PARTICIPANTS T1-weighted and diffusion-weighted imaging scans, from a single research institute, are compared between 19 (9 women) first-trimester DEX-treated individuals, at risk of CAH but not having CAH, and 43 (26 women) controls (age range, 16.0-26.4 years). RESULTS DEX-treated participants showed bilateral enlargement of the amygdala, increased surface area and volume of the left superior frontal gyrus, and widespread increased radial, mean, and axial diffusivity of white matter, in particular in the superior longitudinal fasciculi and corticospinal tracts. In the DEX-treated group, increased mean and radial diffusivity correlated with increased methylation of the promotor region of the FKBP5 gene. There were no group differences in cognition or in scales assessing depression or anxiety, and the relationship between brain structure and cognition did not differ between DEX-treated and controls. CONCLUSIONS First-trimester prenatal DEX treatment is associated with structural alterations of the brain at adult age, with an accompanying change in gene methylation. The findings add to the safety concerns of prenatal DEX treatment in the context of CAH.

Abstract
OBJECTIVE High glucocorticoid levels in rodents inhibit development of beta cells during fetal life and lead to insulin deficiency in adulthood. To test whether similar phenomena occur in humans, we compared beta-cell function in adults who were exposed to glucocorticoids during the first part of fetal life with that of nonexposed subjects. RESEARCH DESIGN AND METHODS The study was conducted in 16 adult participants exposed to glucocorticoids during the first part of fetal life and in 16 nonexposed healthy participants with normal glucose tolerance who were matched for age, sex, and body mass index (BMI). Exposed participants had been born to mothers who were treated with dexamethasone 1 to 1.5 mg/day from the sixth gestational week (GW) to prevent genital virilization in children at risk of 21-hydroxylase deficiency. We selected offspring of mothers who stopped dexamethasone before the 18th GW following negative genotyping of the fetus. Insulin and glucagon secretion were measured during an oral glucose tolerance test (OGTT) and graded intravenous (IV) glucose and arginine tests. Insulin sensitivity was measured by hyperinsulinemic-euglycemic-clamp. RESULTS Age, BMI, and anthropometric characteristics were similar in the 2 groups. Insulinogenic index during OGTT and insulin sensitivity during the clamp were similar in the 2 groups. In exposed subjects, insulin secretion during graded IV glucose infusion and after arginine administration decreased by 17% (P = 0.02) and 22% (P = 0.002), respectively, while glucagon secretion after arginine increased. CONCLUSION Overexposure to glucocorticoids during the first part of fetal life is associated with lower insulin secretion at adult age, which may lead to abnormal glucose tolerance later in life.

Abstract
Prenatal dexamethasone (DEX) treatment in congenital adrenal hyperplasia (CAH) is effective in reducing virilization in affected girls, but potential long-term adverse effects are largely unknown. In this report we intended to explore potential side effects of DEX therapy to enhance the adequacy of future risk benefit analyses of DEX treatment. We investigated the long-term effects of first trimester prenatal DEX treatment on behavioral problems and temperament in children and adolescents aged 7-17 years. The study included 34 children and adolescents, without CAH, who had been exposed to DEX during the first trimester and 67 untreated controls. Standardized parent-completed questionnaires were used to evaluate adaptive functioning and behavioral/emotional problems (CBCL), social anxiety (SPAI-C-P), and temperament (EAS) in the child. Self-reports were used to assess the children's perception of social anxiety (SASC-R). No statistically significant differences were found between DEX-treated and control children and adolescents, suggesting that, in general, healthy children treated with DEX during early fetal life are well adjusted.

Abstract
Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is an autosomal recessive disorder caused by mutations in the CYP21A2 gene. Females affected with classical CAH are at risk for genital ambiguity, but can be treated in utero with dexamethasone before 9 gestational weeks to prevent virilization. Early genetic diagnosis is unavailable through current invasive methods of chorionic villus sampling and amniocentesis. New developments in prenatal genetic testing utilize fetal DNA extracted from maternal blood through noninvasive methods, which allow the determination of fetal gender and the diagnosis of CAH at an early gestational age (<9 weeks). Noninvasive prenatal diagnosis allows for the establishment of early and effective management plans in fetuses at risk for CAH and avoids unnecessary prenatal dexamethasone treatment.

Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the authors due to technical errors that have called into question the reliability of the data used to inform the author's conclusions. All data on cognitive and behavioral outcomes in CAH and non–CAH cases, treated or not treated with DEX prenatally, were put into a single Excel database. The authors had in total four different patient groups for each age group (5–6 y, 7–17 y and 18-35 y). The database consisted of 237 cases in total and there were multiple columns for the different outcome measures. When the behavioral data for the sub-cohort described in this paper (first trimester treated non-CAH cases and healthy population controls, age 7–17 y) were copied to another sheet and compressed/modified in preparation for statistical analysis in SPSS, an error occurred. This technological issue caused rows to shift and the data from the different groups got mixed up. In particular, the non–CAH group versus the control group were "contaminated" with cases from the wrong patient group. The authors discovered this mistake when they started to analyse the data from the other sub–groups of patients, the CAH cases and the adult cohort, which was after their original results had already been published in Hormones and Behavior in this manuscript "Evaluation of behavioral problems after prenatal dexamethasone treatment in Swedish adolescents at risk of CAH". It then became apparent that the entire data set was unreliable and needed to be re–analysed which is what has motivated the retraction of this article. The authors have recently completed this re–analysis and the results have been published here: https://www.sciencedirect.com/science/article/pii/S0018506X17300752

Abstract
Prenatal treatment of congenital adrenal hyperplasia by administering dexamethasone to a woman presumed to be carrying an at-risk fetus remains a controversial experimental treatment. Review of data from animal experimentation and human trials indicates that dexamethasone cannot be considered safe for the fetus. In animals, prenatal dexamethasone decreases birth weight, affects renal, pancreatic beta cell and brain development, increases anxiety and predisposes to adult hypertension and hyperglycemia. In human studies, prenatal dexamethasone is associated with orofacial clefts, decreased birth weight, poorer verbal working memory, and poorer self-perception of scholastic and social competence. Numerous medical societies have cautioned that prenatal treatment of adrenal hyperplasia with dexamethasone is not appropriate for routine clinical practice and should only be done in Institutional Review Board approved, prospective clinical research settings with written informed consent. The data indicate that this treatment is inconsistent with the classic medical ethical maxim to 'first do no harm'.

Abstract
CONTEXT Prenatal dexamethasone (DEX) treatment has been proposed since 1984 to prevent genital virilization in girls with congenital adrenal hyperplasia (CAH). DEX is effective in CAH females if initiated before the sixth week of gestation, but its safety in children treated in utero remains controversial regarding cognitive functions. OBJECTIVE To avoid prenatal DEX in males and initiate DEX in due time in CAH females, we proposed in 2002 a protocol for fetal sex determination in the maternal serum (SRY test). DESIGN AND SETTING We conducted a retrospective study of the management of 258 fetuses in the period 2002 through 2011 in pregnancies managed in referent medical centers with an institutional practice. PATIENTS A total of 258 fetuses at risk of CAH (134 males and 124 females) were included. INTERVENTION DEX was offered after informed consent to pregnant women. MAIN OUTCOME MEASURE The sensitivity of an early SRY test was evaluated after data collection. RESULTS The SRY test is sensitive from 4 weeks and 5 days of gestation. It avoided prenatal DEX in 68% of males, and this percentage increased over the years. DEX was maintained until prenatal diagnosis in non-CAH females. Virilization was prevented in 12 CAH girls treated at the latest at 6 weeks gestation and minimized in 3 girls treated between 6 and 7 weeks gestation. Maternal tolerance was correct. No fetal malformations were noted in the 154 children treated in utero. CONCLUSIONS The SRY test is reliable to avoid prenatal DEX in males, but its application must be improved. Prenatal DEX should be maintained to prevent virilization and traumatic surgery in CAH girls after informed consent and information provided to families about the benefit to risk ratio in limiting hyperandrogenism during fetal life. Our large multicentric French cohort has helped to better assess the risks previously reported.

Abstract
CONTEXT The 21-hydroxylase deficiency is the most common cause of congenital adrenal hyperplasia. Pregnant women presenting a risk of genetic transmission may be treated with synthetic glucocorticoids such as dexamethasone (DEX) to prevent female fetus virilization. OBJECTIVE The aim of this study was to assess the potential deleterious effects of DEX exposure on fetal ovarian development. SETTINGS Human fetal ovaries, ranging from 8-11 weeks after fertilization, were harvested from material available after legally induced abortions. They were cultured in the absence or presence of DEX (2, 10, or 50 μm) over 14 d, and histological analyses were performed. RESULTS The glucocorticoid receptor NR3C1 was present and the signaling pathway active in the fetal ovary as demonstrated by the expression of NR3C1 target genes, such as PLZF and FKBP5, in response to DEX exposure. DEX decreased germ cell density at the 10 and 50 μm doses. Exposure to DEX, even at the highest dose, did not change oogonial proliferation as monitored by 5-bromo-2'-deoxyuridine incorporation and significantly increased the apoptotic rate, detected with cleaved caspase 3 staining. Interestingly, the expression of the prosurvival gene KIT was significantly decreased in the presence of DEX during the course of the culture. CONCLUSION We have demonstrated for the first time that in vitro exposure to high doses of DEX impairs human fetal oogenesis through an increase in apoptosis. These data are of high importance, and additional epidemiological studies are required to investigate the female fertility of those women who have been exposed to DEX during fetal life.

Abstract
CONTEXT Prenatal treatment with dexamethasone to prevent virilization in pregnancies at risk for classical congenital adrenal hyperplasia (CAH) remains controversial. OBJECTIVE To conduct a systematic review and meta-analyses of studies that evaluated the effects of dexamethasone administration during pregnancies at risk for classical CAH because of 21-hydroxylase deficiency (CYP21A2). DATA SOURCES We searched MEDLINE, EMBASE, and Cochrane CENTRAL from inception through August 2009. Review of reference lists and contact with CAH experts further identified candidate studies. STUDY SELECTION Reviewers working independently and in duplicate determined trial eligibility. Eligible studies reported the effects on either foetal or maternal outcomes of dexamethasone administered during pregnancy compared to a control group that did not receive any treatment. DATA EXTRACTION Reviewers working independently and in duplicate determined the methodological quality of studies and collected data on patient characteristics, interventions, and outcomes. DATA SYNTHESIS We identified only four eligible observational studies (325 pregnancies treated with dexamethasone). The methodological quality of the included studies was overall low. Meta-analysis demonstrates a reduction in foetus virilization measured by Prader score in female foetuses treated with dexamethasone initiated early during pregnancy (weighted mean difference, -2.33, 95% CI, -3.38, -1.27). No deleterious effects of dexamethasone on stillbirths, spontaneous abortions, foetal malformations, neuropsychological or developmental outcomes were found although these data are quite sparse. There was increased oedema and striae in the mothers treated with dexamethasone. There were no data on long-term follow-up of physical and metabolic outcomes in children exposed to dexamethasone. CONCLUSIONS The observational nature of the available evidence and the overall small sample size of the whole body of the literature significantly weaken inferences about the benefits and harms of dexamethasone in this setting. Dexamethasone seems to be associated with reduction in foetus virilization without significant maternal or foetal adverse effects. However, this review underscores the current uncertainty and further investigation is clearly needed. The decision about initiating treatment should be based on patients' values and preferences and requires fully informed and consenting parents.

Abstract
On February 3, 2010, a "Letter of Concern from Bioethicists," organized by fetaldex.org, was sent to report suspected violations of the ethics of human subjects research in the off-label use of dexamethasone during pregnancy by Dr. Maria New. Copies of this letter were submitted to the FDA Office of Pediatric Therapeutics, the Department of Health and Human Services (DHHS) Office for Human Research Protections, and three universities where Dr. New has held or holds appointments. We provide a critical appraisal of the Letter of Concern and show that it makes false claims, misrepresents scientific publications and websites, fails to meet standards of evidence-based reasoning, makes undocumented claims, treats as settled matters what are, instead, ongoing controversies, offers "mere opinion" as a substitute for argument, and makes contradictory claims. The Letter of Concern is a case study in unethical transgressive bioethics. We call on fetaldex.org to withdraw the letter and for co-signatories to withdraw their approval of it.

Abstract
CONTEXT AND OBJECTIVE In Sweden, from 1985 through 1995, 40 fetuses at risk for congenital adrenal hyperplasia (CAH) were treated with dexamethasone (DEX) to prevent virilization of affected females. We report long-term effects on neuropsychological functions and scholastic performance of this controversial treatment. DESIGN AND PATIENTS Prenatally treated children, 7 to 17 yr old, were assessed with standardized neuropsychological tests (A Developmental Neuropsychological Assessment and Wechsler Intelligence Scales for Children) and child-completed questionnaires measuring self-perceived scholastic competence (Self-Perception Profile for Children). A parent-completed questionnaire (Child Behavior Checklist/4-18 School Scale) was used to evaluate whether the treatment had any impact on the children's school performance. In addition, a child-completed questionnaire measuring social anxiety (The Social Anxiety Scale for Children-Revised) was completed by the prenatally treated children aged 8 to 17 yr (n = 21) and age- and sex-matched controls (n = 26). RESULTS Of 40 DEX-treated children, 26 (median age, 11 yr) participated in the study. Thirty-five sex- and age-matched healthy children were controls. There were no between-group differences concerning psychometric intelligence, measures of cerebral lateralization, memory encoding, and long-term memory. Short-term treated, CAH-unaffected children performed poorer than the control group on a test assessing verbal working memory (P = 0.003), and they rated lower on a questionnaire assessing self-perception of scholastic competence (P = 0.003). This group also showed increased self-rated social anxiety assessed by The Social Anxiety Scale for Children-Revised (P = 0.026). Prenatally treated, CAH-affected children performed poorer than controls on tests measuring verbal processing speed, although this difference disappeared when controlling for the child's full-scale IQ. CONCLUSIONS This study indicates that prenatal DEX treatment is associated with previously not described long-term effects on verbal working memory and on certain aspects of self-perception that could be related to poorer verbal working memory. These findings may thus question future DEX treatment of congenital adrenal hyperplasia. Therefore, we encourage additional retrospective studies of larger cohorts to either confirm or challenge the present findings.

Abstract
11beta-Hydroxylase deficiency is a common form of congenital adrenal hyperplasia causing virilization of the female fetus and hypertension. DNA analysis of the gene (CYP11B1) encoding 11beta-hydroxylase has been reported previously to be effective in the prenatal diagnosis of one affected female fetus. In that case, prenatal treatment with dexamethasone resulted in normal female genitalia. We now report five new pregnancies that underwent prenatal diagnosis for 11beta-hydroxylase deficiency. In the first family, the proband is homozygous for a T318M mutation and all fetuses from four subsequent pregnancies are carriers. In a second family, the mother is homozygous for a A331V mutation and was started on dexamethasone, but identification of a homozygous normal fetus led to the discontinuation of treatment. In another family, the fetus was a male homozygous for R384Q and treatment was discontinued. Lastly, a novel G444D mutation in exon 8 was identified and proven to reduce 11beta-hydroxylase activity.

Abstract
In foetuses at risk of virilising congenital adrenal hyperplasia (CAH), prenatal treatment can be offered by administration of dexamethasone (DEX) via the mother, in order to suppress foetal adrenal androgen oversecretion and prevent genital malformations. The first treated cases were described 20 years ago, and several hundred pregnancies have been reported since. There is a consensus that the treatment effectively prevents or reduces virilisation, but opinions regarding its safety differ. Rare adverse events have been reported in treated children, but no harmful effect has been documented that can be clearly attributed to the treatment. However, few treated foetuses have been followed until adolescence. Animal studies and epidemiological data point to various adverse effects of excess glucocorticoids on the developing foetus. In order to prevent virilisation effectively in females affected with CAH, the prenatal treatment needs to be instituted in the early first trimester, before prenatal diagnosis is possible. Thus, a majority of treated foetuses will receive DEX unnecessarily. The PREDEX study was initiated in Stockholm in 1999 as an open, controlled, non-randomised, multicentre trial. Participating centres are Stockholm, Bergen, Kuopio, Warsaw, London, Lyon and Barcelona. The study has been approved by the ethics committees in each country. The purpose of PREDEX is to evaluate prospectively the prenatal treatment regarding efficacy in preventing virilisation as well as to study its safety for both mothers and treated children. Children are followed until 18 years of age and a wide range of physiological, metabolic and developmental parameters are considered. In Sweden, treatment is not offered outside the frames of the trial.

Abstract
Congenital adrenal hyperplasia (CAH) refers to a family of monogenic inherited disorders of adrenal steroidogenesis most often caused by enzyme 21-hydroxylase deficiency (21-OHD). In the classic forms of CAH (simple virilizing and salt wasting), androgen excess causes external genital ambiguity in newborn females and progressive postnatal virilization in males and females. Prenatal treatment of CAH with dexamethasone has been successfully used for over a decade. This article serves as an update on 532 pregnancies prenatally diagnosed using amniocentesis or chorionic villus sampling between 1978 and 2001 at New York Presbyterian Hospital-Weill Medical College of Cornell University. Of the 532 pregnancies, 281 were prenatally treated for CAH due to the risk of 21-hydroxylase deficiency. Follow-up telephone interviews with mothers, genetic counselors, endocrinologists, pediatricians, and obstetricians were performed in all cases. Of the pregnancies evaluated, 116 babies were affected with classic 21-OHD. Of these, 61 were female, 49 of whom were treated prenatally with dexamethasone. Dexamethasone administered at or before 9 wk gestation (in proper doses) was effective in reducing virilization. There were no statistical differences in the symptoms during pregnancy between mothers treated with dexamethasone and those not treated with dexamethasone, except for weight gain, edema, and striae, which were greater in the treated group. No significant or enduring side-effects were noted in the fetuses, indicating that dexamethasone treatment is safe. Prenatally treated newborns did not differ in weight from untreated, unaffected newborns. Based on our experience, prenatal diagnosis and proper prenatal treatment of 21-OHD are effective in significantly reducing or eliminating virilization in the newborn female. This spares the affected female the consequences of genital ambiguity, genital surgery, and possible sex misassignment.

Abstract
Congenital adrenal hyperplasia (CAH) consists of autosomal recessive disorders of cortisol biosynthesis, which in the majority of cases result from 21-hydroxylase deficiency. Another enzymatic defect causing CAH is 11beta-hydroxylase deficiency. In both forms, the resulting excessive androgen secretion causes genital virilization of the female fetus. For over 10 yr female fetuses affected with 21-hydroxylase deficiency have been safely and successfully prenatally treated with dexamethasone. We report here the first successful prenatal treatment with dexamethasone of an affected female with 11beta-hydroxylase deficiency CAH. The family had two girls affected with 1beta-hydroxylase deficiency born with severe ambiguous genitalia who were both homozygous for the T318M mutation in the CYP11B1 gene, which codes for the 11beta-hydroxylase enzyme. In the third pregnancy in this family, the female fetus was treated in utero by administering dexamethasone to the mother, starting at 5 weeks gestation. The treatment was successful, as the newborn was not virilized and had normal female external genitalia. A second family with two affected sons was also studied in preparation for a future pregnancy. We report a novel 1-bp deletion in codon 394 (R394delta1) in the CYP11B1 gene in this family.

Abstract
Women with congenital adrenal hyperplasia due to 21-hydroxylase deficiency, especially those patients with the salt-losing form, have decreased fertility rates. Pregnancy experience in this population is limited. We report the pregnancy outcomes and serial measurements of maternal serum steroid levels in four women with classic 21-hydroxylase deficiency, three of whom were female pseudohermaphrodites with the salt-losing form. These glucocorticoid-treated women gave birth to four healthy female newborns with normal female external genitalia, none of whom were affected with 21-hydroxylase deficiency. In three women, circulating androgen levels increased during gestation, but remained within the normal range for pregnancy during glucocorticoid therapy. In the fourth patient, androgen levels were strikingly elevated during gestation despite increasing the dose of oral prednisone from 5 to 15 mg/day (two divided doses). Notwithstanding the high maternal serum concentration of androgens, however, placental aromatase activity was sufficient to prevent masculinization of the external genitalia of the female fetus and quite likely the fetal brain, consistent with the idea that placental aromatization of androgens to estrogens is the principal mechanism that protects the female fetus from the masculinizing effects of maternal hyperandrogenism. These four patients highlight key issues in the management of pregnancy in women with 21-hydroxylase deficiency, particularly the use of endocrine monitoring to assess adrenal androgen suppression in the mother, especially when the fetus is female. Recommendations for the management of pregnancy and delivery in these patients are discussed.

Abstract
Congenital adrenal hyperplasia (CAH) is the common name of a constellation of diseases that impair cortisol synthesis in the adrenal cortex. As defects in each of three steroidogenic enzymes, 21-hydroxylase, 11 beta-hydroxylase, and 3 beta-hydroxysteroid dehydrogenase, promote overproduction of adrenal androgens, affected female fetuses may be virilised. The major cause of CAH is 21-hydroxylase deficiency, the incidence of which is 1:10,000 live births in the Swedish population. Of the 10-15 children born in Sweden each year with 21-hydroxylase deficiency, 3-5 will be virilised girls who must undergo traumatic surgery of the external genitalia. This can be prevented by administration of dexamethasone to the gravida during pregnancy. Prenatal treatment was introduced in Sweden in 1985, prenatal diagnosis being based in most cases on direct mutational analysis using allele-specific PCR on DNA from chorionic villus samples. In our experience, genotype corresponds well to phenotype, and we recommend that all children with 21-hydroxylase deficiency be genotyped in order to prepare the family for rapid and reliable prenatal diagnosis and possible treatment when the next child is awaited. Since 1985, 35 women have received prenatal treatment in Sweden, six of the 35 fetuses being found to be affected females and treated until term. As compared with their older sisters, all of these six girls were characterised by no signs, or only minor signs, of virilisation, and only one required surgery because of labial fusion and recurrent urinary tract infections. As a group, the 35 infants were characterised by normal birth weight and length, and normal growth during the first year of life. Passage of developmental milestones was normal though several adverse events, both in treated mothers and infants, have been reported. Approximately one fourth of the women treated throughout pregnancy reported some side-effect (e.g., excessive weight gain, severe cutaneous striae, mood fluctuations and irritability, acne and hirsutism, or oedema). One unaffected boy, treated for seven weeks, was born with severe hydrocephalus and agenesis of the corpus callosum; two affected sisters and one unaffected girl were characterised by failure to thrive during the first year of life, but later recovered (one of the affected sisters was later diagnosed as suffering from mitochondrial disease). Although in our experience prenatal treatment with dexamethasone is effective in preventing virilisation of girls with 21-hydroxylase deficiency, some adverse events have been noted in treated infants. As it remains unknown whether these events were attributable to the treatment, it must still be regarded as experimental, and its use should be centralised and meticulously monitored until more experience has been gained.

Abstract
We report two cases of congenital adrenal hyperplasia (CAH) in which administration of chlormadinone acetate (CMA), a substituted progestational agent for prostatic disease, suppressed ACTH hypersecretion and lowered plasma testosterone levels. Case 1 was 83-year-old male with advanced prostatic carcinoma and CAH due to 21-hydroxylase deficiency. His plasma testosterone did not decrease in spite of a bilateral orchiectomy. Case 2 was 40-year-old female with CAH due to 21-hydroxylase deficiency suffering from virilization after the cessation of cortisol supplement therapy because of her breast carcinoma. In these two cases, oral administration of CMA at a daily dose of 75-100 mg suppressed ACTH and cortisol to subnormal levels and reduced testosterone levels. With the suppressive effect on ACTH excess and antiandrogenic action, CMA may be suitable for patients with CAH suffering from symptoms due to overproduced ACTH or adrenal androgen.

Abstract
Advances in technology have made possible the prenatal diagnosis and treatment of female fetuses with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Hormonal measurement of 17-hydroxyprogesterone, androstenedione, testosterone and 21-deoxycortisol and HLA typing and DNA analysis for 21-OH/C4/HLA class I and II genes in chorionic villus cells and amniocytes are utilized for prenatal diagnosis. Maternal dexamethasone administration begun in the first trimester has prevented or ameliorated virilization in approximately three-fourths of infants. Maternal estriol levels appear to be the most accurate measure of fetal adrenal suppression. Maternal side effects are not infrequent and include excess weight gain, edema, glucose intolerance, hypertension and gastrointestinal problems. Severe permanent striae have been reported. Although no complications of prenatal treatment in the treated fetus or child have been reported long-term follow-up with careful neuropsychologic evaluation is not yet available and is necessary to fully evaluate possible long-term side-effects of prenatal dexamethasone treatment.

Abstract
Prenatal treatment based on administration of dexamethasone to the mother during pregnancy was initiated early during nine pregnancies with a high risk of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. The purpose of this treatment was to prevent fetal virilization by reducing production of androgens by the adrenal glands. Prenatal diagnosis was achieved by comparing amniotic fluid cell HLA genotypes and more recently by subjecting trophoblasts to molecular genetic studies. Together with prenatal determination of fetal sex, this allowed to determine that only two female fetuses were affected. Efficacy of continued prenatal treatment in these two cases was good in one case and mediocre in the other. The treatment was well tolerated by the mothers and fetuses.

Abstract
Prenatal diagnosis of 21-hydroxylase deficiency, the most common cause of congenital adrenal hyperplasia (CAH), has benefited from the advances in endocrinologic and molecular genetic studies. In 1976, prenatal diagnosis of the disease was first attempted by measuring 17-hydroxyprogesterone in the amniotic fluid in the second trimester of pregnancy. Discovery of a close linkage between HLA and the disease gave a second approach for prenatal diagnosis, the latter being made by linkage study of the haplotypes of the index case in a given family. Diagnosis was later made directly by molecular biology. Currently, the studies of the C4-CYP21B gene locus by Southern blotting and the CYP21B gene mutations by PCR methods simplify the diagnostic procedure of an early and accurate prenatal diagnosis in the first trimester. In these conditions all families are now informative. Moreover, using a direct genetic analysis associated with the possibility of detecting the heterozygotes in a non-related CAH population, a prenatal diagnosis can be done in a family without a previously CAH affected child. From our results in a series of 274 pregnancies at risk for CAH in whom prenatal diagnosis has been made by these different approaches, it can be concluded that steroid analysis in the amniotic fluid is an accurate method but provides only a late (second trimester) diagnosis, while an early and accurate diagnosis now relies on adequate molecular genetic studies on chorion villus biopsies. In the aim to prevent the virilization of the external genitalia in CAH female fetuses, prenatal treatment was instituted in our group in 1979 by giving dexamethasone to the mother. This prenatal treatment appears safe for the fetus and the child and is effective in preventing virilization of CAH affected females. Although the degree of prevention is not always complete in all cases, the advantages of prenatal treatment are prevailing over the complications observed in a few mothers.

Abstract
A retrospective study of all Swedish patients with congenital adrenal hyperplasia (CAH) born 1969-1986, was conducted to elucidate possible benefits of neonatal screening for CAH. Information was obtained about 150 patients (67 male, 83 female). One hundred and forty-three cases were regarded as classical and seven as non-classical (symptoms after 5 years of age or cryptic). All but two (one girl with 11-hydroxylase deficiency and one boy with beta-hydroxysteroid-dehydrogenase deficiency) had 21-hydroxylase deficiency. The prevalence was 1:11,500. Ninety-three patients (48 male, 45 female) displayed salt loss, all before the age of 3 months. Two boys had died and many children had been critically ill during the first weeks of life. The median age at diagnosis for boys in this group was 21 days. Gender assignment was a major problem in 38 of 57 girls with ambiguous genitalia noticed during the first day. Fifteen of these girls were considered to be male for their first 40 days (median), before the CAH diagnosis was established. Patients in whom the first symptom was manifested after the age of one year often showed growth acceleration, which frequently was overlooked. Median diagnostic delay in this group was 17 months. Possible benefits of neonatal screening are: avoidance of a serious salt-loss crisis; earlier diagnosis and correct gender assignment in virilized girls; decreased virilization, growth acceleration and premature pubarche in prepubertal children; and reduced negative consequences for psycho-social development and final height.
