NCCAH patients who are diagnosed during childhood with signs of PP may be treated with hydrocortisone with the aim of suppressing the adrenal hormones and preventing rapid advancement of bone age that could affect final height. The decision about initiating treatment should be undertaken only in large centers with an experienced team and protocols approved by Institutional Review Boards and based on the family's values and preferences and with their written informed consent as a prerequisite (19, 63). Hydrocortisone is typically used in children, as it most closely resembles the natural hormone (cortisol), but it is not considered a suitable approach in adolescents and young females due to the need for multiple daily dosing. Treatment includes carefully monitored hormone replacement therapy. Int J Pediatr Endocrinol. A single copy of these materials may be reprinted for noncommercial personal use only. Treatment should be initiated not only to address the main cause of the patient's visit but additionally to decrease abnormally elevated hormone concentrations. Horm Res. Bonfig W, Bechtold S, Schmidt H, Knorr D, Schwarz HP. The Hospital Anxiety and Depression Scale (HADS) questionnaire also revealed increased anxiety scores (41). Both classic and nonclassic forms of the disease are caused by deficiencies in the adrenal enzymes that are used to synthesize glucocorticoids. have pointed out, if the sum of basal and post-stimulation 17 OHP values exceeds 1.5 nmol/L, then the possibility of heterozygosity is exceptionally high (20). Working in this direction, novel studies point to the use of cell-free fetal DNA obtained from maternal plasma as a promising method that will allow the determination of fetal gender and the diagnosis of CAH at an early gestational age (<9 weeks). In children who have nonclassic CAH, signs and symptoms of early puberty may appear. When mild congenital adrenal hyperplasia is suspected, elevated serum levels of 17-hydroxyprogesterone suggest 21-hydroxylase deficiency, and elevated deoxycorticosterone/11-deoxycortisol levels suggest 11- hydroxylase deficiency (Table 1; Figures 4 and 5). Clin Endocrinol. At the other end of the spectrum is the issue of alopecia. Regular growth pattern, a bone age compatible to chronological age, and absence of central obesity may also serve as clinical indices for appropriate management.

Glucocorticoid treatment regimen and health outcomes in adults with congenital adrenal hyperplasia. The adrenal glands produce important hormones, including: In people who have CAH, a gene change (mutation) results in a lack of one of the enzymes needed to make these hormones. Voutilainen R, Jskelinen J. Lastly, given that many therapeutic issues related to the appropriate management of these patients have not as yet been elucidated, it is very important for the attending physician to keep up to date with all developments in this field and to integrate the new data into his clinical practice. Hence all patients with NCCAH should be offered genetic counseling and molecular assessment of reproductive partners. OMIM Entry - * 613815 - CYTOCHROME P450 FAMILY 21 SUBFAMILY A POLYPEPTIDE 2; CYP21A2. Bearing in mind these findings, psychological parameters to guide therapy should be considered in women with NCCAH and, in the context of the patient-oriented approach, a psychological diagnosis and support need to be offered. Non-classical congenital adrenal hyperplasia (NCCAH) is considered to be a common monogenic inherited disease, with an incidence range from 1:500 to 1:100 births worldwide. Additionally, many individuals remain asymptomatic during childhood and adolescence, have normal reproductive function, and only become aware of NCCAH due to the diagnosis of another family member and consequent testing (11). Retrospective clinical-qualitative interviews with these women revealed a history of discomfort and social stress related to their pre-treatment experiences with androgen-dependent signs, such as acne, hirsutism, and conception difficulties (59, 77, 78). Hoepffner W, Kaufhold A, Willgerodt H, Keller E. Patients with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency can achieve their target height: the Leipzig experience. BMJ Case Rep. (2013) 2013:bcr2013010123. doi: 10.1159/000369901, 26. Marnach ML (expert opinion). Moran C, Azziz R, Weintrob N, Witchel SF, Rohmer V, Dewailly D, et al. However, most women with NCCAH seek medical assistance when they experience symptoms of androgen excess and, when clinical suspicion prompts testing, elevated basal 17 OHP levels will more likely than not point to a diagnosis of NCCAH. According to other studies, a baseline value of 17 OHP between 5.1 and 9 nmol/L is sufficient for the diagnosis of NCCAH (13, 16, 17). (1985) 37:65067. Gastaud F, Bouvattier C, Duranteau L, Brauner R, Thibaud E, Kutten F, et al. They must also know that the probability that their child will suffer from the classical form of the disease is high, despite treatment. J Clin Endocrinol Metab. doi: 10.1530/EJE-11-0019, 76. (1982) 55:81727. In those patients in whom hydrocortisone treatment was initiated 1 year before the onset of puberty and who had a bone age below 9 years, final height remained within the genetic potential (47). One hundred years of congenital adrenal hyperplasia in Sweden: a retrospective, population-based cohort study. Often there are no symptoms of nonclassic CAH when a baby is born. doi: 10.1007/s12020-015-0656-0, 33. (2011) 96:161022. Accessed Dec. 8, 2021. Heterozygotes carrying one CYP21A2 mutation exhibit slightly elevated 17 OHP levels post ACTH stimulation, though there is overlap in unaffected subjects (9). Furthermore, women with NCCAH commonly experience subfertility, therefore, there will be analysis of the appropriate approach for these patients, including during pregnancy, based mainly on genotype. Planning of suggested procedures during pregnancy based on prospective parents genotype. can lead full lives. Congenital adrenal hyperplasia (CAH) encompasses a family of autosomal recessive disorders characterized by mild to acutely impaired cortisol synthesis due to a deficiency in one of the five adrenal steroidogenic enzymes required for cortisol production (1, 2). doi: 10.1210/jc.2009-1383. In such a case, a parallel course with GnRH analog may be prescribed if bone age is significantly higher than chronological age and/or projected final height is disproportionate to target height. NCCAH is much more frequent, occurring in approximately 1 out of 1,000 Caucasians and more commonly in certain ethnic groups, such as Ashkenazi Jews (1:27), Hispanics (1:53), Yugoslavs (1:62), and Italians (1:300) (5, 6). The aim of prenatal treatment of CAH is the prevention of genital virilization of the fetus, but also alleviation of the stress felt by the parents who are likely to have a child with ambiguous genitalia (70). Fertil Steril. Of course, further studies are needed to verify or reject this finding. J Clin Endocrinol Metab. doi: 10.1530/eje.0.1360188, 48. doi: 10.1210/jc.2018-01865, 61. This time interval suggests that all pregnancies at risk for virilizing CAH should be treated, even though only 1 out of 8 fetuses is affected and female (19, 34, 70). doi: 10.1210/jc.2006-1645, 60. Nebesio TD, Renbarger JL, Nabhan ZM, Ross SE, Slaven JE, Li L, et al. Since cortisol affects almost 20% of the human genome, diverse responses of different GCs are expected in various tissues. 17 OHP levels are measured by a variety of immunoassay methods, but as has recently been shown, the most accurate and reliable results were achieved by the implementation of the combination of liquid chromatography with mass spectrometry (LC-MS/MS). The urinary opening (urethra) and the vagina may be only one opening instead of two separate openings. The uterus, fallopian tubes and ovaries usually develop typically. Miller WL, Witchel SF. Birnbaum MD, Rose LI. Miller WL. Mayo Clinic. Clin Chim Acta. Acne is reported in almost 33% of NCCAH subjects (36). The clinical expression of NCCAH is characterized by a high level of polymorphism as concerns not only age of onset but also the different signs and symptoms. (2006) 118:224550. Besides, we should keep in mind that since the same patient will have changing requirements through the years, the attending physician should undertake a tailor-made approach in order to cover her specific needs at different stages of life. This is known as the autosomal recessive inheritance pattern. Ludwig E. Classification of the types of androgenetic alopecia (common baldness) occurring in the female sex. (2013) 78:74750. (2010) 49:1395400. Speiser PW, Dupont J, Zhu D, Serrat J, Buegeleisen M, Tusie-Luna MT, et al. Perched on top of each of your kidneys, your adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure and other essential functions. (2012) 25:101721. Wilson RC, Nimkarn S, Dumic M, Obeid J, Azar MR, Azar M, et al. Recognition of the problem and timely replacement therapy can reduce morbidity and enhance quality of life in patients that are affected by congenital adrenal hyperplasia. In a multicenter study, the most common symptoms among adolescent and adult women were hirsutism (59%), oligomenorrhea (54%), and acne (33%). A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. doi: 10.1038/nrendo.2009.148, 11. The use of flutamide (Eulexin), an androgen inhibitor, in a dosage of approximately 10 mg per kg per day in three divided doses, in patients with all types of congenital adrenal hyperplasia may permit hydrocortisone to be given at lower dosages.8,9 Aromatase inhibitors that prevent conversion of androgens to estrogen (such as testolactone [Teslac], in a dosage of 40 mg per kg per day), may help children with mild congenital adrenal hyperplasia to achieve their height potential.1,8,9. N Engl J Med. Neonatal screening for congenital adrenal hyperplasia. An excess of the male sex hormone androgen can result in short height and early puberty for both males and females. Ann Intern Med. This enzyme is required by the body to make proper amounts of hormones. All authors listed have made a substantial, direct and intellectual contribution to the work, and approved it for publication. Congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency: an endocrine society clinical practice guideline. (2004) 112:34355.

Menstruation in girls and adolescents: using the menstrual cycle as a vital sign. Regarding biochemical/ hormonal profile, androstenedione and testosterone levels in the mid to upper ranges for bone age are considered better markers of adequate GC replacement therapy in children with NCCAH. Menstrual irregularities including oligomenorrhea or secondary amenorrhea can often be the presenting sign of NCCAH in post menarche individuals. compared the hormonal effects and pharmacokinetics of hydrocortisone, prednisolone, and dexamethasone in 9 prepubertal patients with CCAH. One may suggest the use of a Synacthen test, and if it is not compatible with heterozygosity (sum of basal and peak stimulated 17 OHP values < 1.5 nmol/L), then DNA testing could be avoided. doi: 10.1136/bcr-2013-010123, 32. (1994) 62:73843. (2007) 92:13916. Hydrocortisone supplementation, though not dexamethasone administration, could, as a general rule, be helpful, however, at minimum doses, and also for a short period of time and, most likely, not lifelong. An alternative indication for starting hydrocortisone treatment is an inadequate cortisol response post ACTH stimulation (36). Deneux C, Tardy V, Anne D, Mornet E, Billaud L, Charron D, et al. Steroid 21-hydroxylase deficiency: genotype may not predict phenotype. Overdosing should be avoided, considering it that can result in poor growth as well as Cushingoid features. Some of these abnormalities result in severe dysfunction of the enzyme while others result in only partial impairment.35, Classic 11- hydroxylase deficiency occurs in approximately one per 100,000 births and occurs more frequently in Moroccan Jews.

This content does not have an Arabic version. The nonclassic form of CAH doesn't cause adrenal crisis. Weintrob N, Dickerman Z, Sprecher E, Galatzer A, Pertzelan A. Non-classical 21-hydroxylase deficiency in infancy and childhood: the effect of time of initiation of therapy on puberty and final height. Late onset adrenocortical hydroxylase deficiencies associated with menstrual dysfunction. However, adolescent patients frequently do not show sufficient compliance with chronic administration of drugs and often omit doses. Available studies indicate that adult height approached the expected target height in patients that were closely monitored and who strictly complied with medication plans (4850). doi: 10.1111/cen.12045, 45. Whether this constitutes a realistic approach and how much the administered dose should be remain to be elucidated (51). Speiser PW, Azziz R, Baskin LS, Ghizzoni L, Hensle TW, Merke DP, et al. In any case, a diagnosis of NCCAH should be considered during the evaluation of any young woman who is referred for hyperandrogenic symptoms. By contrast to childhood, in adolescence, longer-acting steroids are often used and regimens of 5 mg of prednisolone or 0.25 mg of dexamethasone are recommended (53). Congenital adrenal hyperplasia. Consultation with an endocrinologist is recommended for patients who require complex hormone regimens. Nevertheless, the same couple experienced two miscarriages and reported subfertility after this first pregnancy (66). To sum up, for the NCCAH woman, the ideal approach is a tailor-made one, incorporating a smooth transition of her management once she is referred from the pediatric to the adult endocrinologist, along with symptom-oriented treatment that will accompany her throughout her life.
