Cortical gyrification in women and men and the (missing) link to prenatal androgens.

Previous studies have reported sex differences in cortical gyrification. Since most cortical folding is principally defined in utero, sex chromosomes as well as gonadal hormones are likely to influence sex-specific aspects of local gyrification. Classic congenital adrenal hyperplasia (CAH) causes high levels of androgens during gestation in females, whereas levels in males are largely within the typical male range. Therefore, CAH provides an opportunity to study the possible effects of prenatal androgens on cortical gyrification. Here, we examined the vertex-wise absolute mean curvature-a common estimate for cortical gyrification-in individuals with CAH (33 women and 20 men) and pair-wise matched controls (33 women and 20 men). There was no significant main effect of CAH and no significant CAH-by-sex interaction. However, there was a significant main effect of sex in five cortical regions, where gyrification was increased in women compared to men. These regions were located on the lateral surface of the brain, specifically left middle frontal (rostral and caudal), right inferior frontal, left inferior parietal, and right occipital. There was no cortical region where gyrification was increased in men compared to women. Our findings do not only confirm prior reports of increased cortical gyrification in female brains but also suggest that cortical gyrification is not significantly affected by prenatal androgen exposure. Instead, cortical gyrification might be determined by sex chromosomes either directly or indirectly-the latter potentially by affecting the underlying architecture of the cortex or the size of the intracranial cavity, which is smaller in women.

CAHQL: A patient reported outcome instrument to assess health-related quality of life in congenital adrenal hyperplasia.

CONTEXT: Measuring health-related quality of life (HRQoL) is a crucial aspect of evaluating health care outcomes. Patients with congenital adrenal hyperplasia (CAH) often self-report deficiencies in HRQoL. OBJECTIVE: The aim of our study was to develop a disease-specific patient reported outcome (PRO) instrument to evaluate the HRQoL of patients >16 years old with classic congenital adrenal hyperplasia (CAH). DESIGN, SETTING AND OUTCOMES: Following the FDA guidelines for developing PRO instruments, we developed a conceptual framework for the instrument. A preliminary instrument was created after interviewing a representative sample of 12 patients with CAH between 16 to 68 years old and 3 parents, and obtaining expert feedback from 4 endocrinologists. The instrument was edited after cognitive interviews with 6 patients. Internal consistency of the instrument was evaluated using Cronbach's alpha. Validity was assessed by comparing the scores of our instrument with scores from widely used validated instruments for HRQoL and PRO not specific to CAH. RESULTS: Sixty-nine patients 16 to 75 years old participated in validating our preliminary instrument. The final questionnaire consists of 44 questions within 7 domains: General Health, Adrenal Insufficiency, Glucocorticoid Excess, Physical Functioning, Mental Health and Cognition, Social Functioning, and Sexual Functioning, with acceptable internal consistency (Chronbach's alpha≥0.6) and validity (r = -0.350 to 0.866). CONCLUSION: CAHQL is the first validated PRO instrument to capture disease specific HRQoL outcomes in CAH. In addition to its anticipated use in the clinical setting, the instrument could be used to assess the efficacy of novel treatments in development.

Case report: Development of central precocious puberty in a girl with late-diagnosed simple virilizing congenital adrenal hyperplasia complicated with Williams syndrome.

Congenital adrenal hyperplasia (CAH) and Williams Syndrome (WS; MIM # 194050) are distinct genetic conditions characterized by unique clinical features. 21-Hydroxylase deficiency (21-OHD; MIM #201910), the most common form of CAH, arises from mutations in the CYP21A2 gene, resulting in virilization of the external genitalia in affected females, early puberty in males, and short stature. Williams syndrome, caused by a microdeletion of 7q11.23, presents with distinctive facial features, intellectual disability, unique personality traits, early puberty, and short stature. This case report describe the clinical features of a 4-year-old girl referred due to progressive virilization and developmental delay. Genetic analysis confirmed concurrent CAH and WS, identifying a novel mutation in the CYP21A2 gene (c.1442T>C). Following corticosteroid therapy initiation, the patient developed central precocious puberty. This case report delves into the pubertal change patterns in a patient affected by overlapping genetic conditions, providing valuable insights in to the intricate clinical manifestation and management of these rare complex disorders.

Can incorporating molecular testing improve the accuracy of newborn screening for congenital adrenal hyperplasia?

BACKGROUND: Single-tier newborn screening (NBS) for CAH using 17-hydroxyprogesterone (17OHP) measured by fluoroimmunoassay (FIA) in samples collected at 24-48 hours produces a high false-positive rate (FPR). 2nd tier steroid testing can reduce the FPR and has been widely implemented. We investigated the accuracy of an alternative multi-tier CAH NBS protocol that incorporates molecular testing of the CYP21A2 gene and reduces the 1st tier 17OHP cutoff to minimize missed cases. METHODS: Created a Minnesota-specific CYP21A2 pathogenic variants panel; develop a rapid, high-throughput multiplex, allele-specific-primer-extension assay; perform 1-year retrospective analysis of Minnesota NBS results comparing metrics between a conventional steroid-based two-tier protocol and a molecular-based multi-tier NBS protocol, applied post-hoc. RESULTS: CYP21A2 gene sequencing of 103 Minnesota families resulted in a Minnesota-specific panel of 21 pathogenic variants. Centers for Disease Control and Prevention (CDC) created a molecular assay with 100% accuracy and reproducibility. Two-tier steroid-based screening of 68,659 live births during 2015 resulted in 2 false negatives (FNs), 91 FPs, and 1 true positive (TP). A three-tier protocol with a lower 1st-tier steroid cutoff, 2nd-tier 21-variant CYP21A2 panel and 3rd-tier CYP21A2 sequencing would have resulted in 0 FNs, 52 FPs and 3 TPs. CONCLUSIONS: Incorporation of molecular testing could improve the accuracy of CAH NBS, although some distinct challenges of molecular testing may need to be considered before implementation by NBS programs.

Approaching fertility in congenital adrenal hyperplasia: exploring P30L mutation-induced 21-hydroxylase deficiency with a presentation between non-classical and simple virilizing phenotypes. A case report.

Congenital adrenal hyperplasia (CAH) is determined in the vast majority of cases by mutations in the CYP21A2 gene, which cause the deficiency of the 21 hydroxylase enzyme, which is involved in the synthesis of cortisol and aldosterone. Generally, CAH phenotype and disease severity can be predicted with the genotypes and is related to the residual activity of 21 hydroxylase enzyme. It is divided into classical CAH with salt wasting and simple virilizing forms and non-classical or late-onset CAH forms, respectively. Patients with 21 hydroxylase deficiency, including those with non-classic forms face immense challenges to their fertility. Glucocorticoid therapy has been shown to be useful in obtaining and maintaining a pregnancy among these patients, but it must be used with caution. Given the relevance of CAH in reproductive medicine as well as the diagnostic challenges posed by the phenotypic overlap with polycystic ovary syndrome and by overlap of its own phenotypes (classic CAH-nonclassic CAH), we present the case of a woman with CAH due to 21 hydroxylase deficiency caused by the P30L mutation with a clinical and biochemical presentation between the non-classical form and the classic simple virilizing form. Further, the successful fertility management in this patient and an overview of fertility management in CAH is depicted, as well.

AAV-delivered hepato-adrenal cooperativity in steroidogenesis: Implications for gene therapy for congenital adrenal hyperplasia.

Despite the availability of life-saving corticosteroids for 70 years, treatment for adrenal insufficiency is not able to recapitulate physiological diurnal cortisol secretion and results in numerous complications. Gene therapy is an attractive possibility for monogenic adrenocortical disorders such as congenital adrenal hyperplasia; however, requires further development of gene transfer/editing technologies and knowledge of the target progenitor cell populations. Vectors based on adeno-associated virus are the leading system for direct in vivo gene delivery but have limitations in targeting replicating cell populations such as in the adrenal cortex. One strategy to overcome this technological limitation is to deliver the relevant adrenocortical gene to a currently targetable organ outside of the adrenal cortex. To explore this possibility, we developed a vector encoding human 21-hydroxylase and directed expression to the liver in a mouse model of congenital adrenal hyperplasia. This extra-adrenal expression resulted in reconstitution of the steroidogenic pathway. Aldosterone and renin levels normalized, and corticosterone levels improved sufficiently to reduce adrenal hyperplasia. This strategy could provide an alternative treatment option for monogenic adrenal disorders, particularly for mineralocorticoid defects. These findings also demonstrate, when targeting the adrenal gland, that inadvertent liver transduction should be precluded as it may confound data interpretation.

Isotretinoin-unresponsive acne as a sign of a congenital disorder: a case of 21-hydroxylase deficiency.

Acne is a multifactorial and common disorder among young people and a frequent reason for dermatology consultation. When moderate-to-severe acne is not responsive to conventional treatments, oral isotretinoin is a very effective solution. However, there are cases in which this treatment fails to produce the expected results. In this case, an 18-year-old male patient with acne, unresponsive to traditional acne therapies, experienced only a partial benefit from oral isotretinoin. Endocrinology consultation and hormonal work-up revealed androgen metabolism anomalies suggestive of a non-classical form of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. In this case report, the authors discuss when to suspect, how to diagnose, and how to manage similar cases.

Premature Pubarche: A Pragmatic Approach.

Premature pubarche (PP) is a common and usually benign variant of normal puberty most often seen in 5-year-old to 9-year-old children. Some providers routinely order laboratory testing and a bone age to try to rule out other diagnoses including nonclassic congenital adrenal hyperplasia and gonadal or adrenal tumors. I review the natural history of PP and studies which suggest that without clinical features such as rapid growth and progression or genital enlargement, it is unlikely that a treatable condition will be found. Therefore it is recommended that patients with PP not undergo testing unless there are red flags at the time of the initial visit.

Recommendations for 46,XX Congenital Adrenal Hyperplasia Across Two Decades: Insights from the North American Differences of Sex Development Clinician Survey.

Several aspects of clinical management of 46,XX congenital adrenal hyperplasia (CAH) remain unsettled and controversial. The North American Disorders/Differences of Sex Development (DSD) Clinician Survey investigated changes, over the last two decades, in clinical recommendations by specialists involved in the management of newborns with DSD. Members of the (Lawson Wilkins) Pediatric Endocrine Society and the Societies for Pediatric Urology participated in a web-based survey at three timepoints: 2003-2004 (T1, n = 432), 2010-2011 (T2, n = 441), and 2020 (T3, n = 272). Participants were presented with two clinical case scenarios-newborns with 46,XX CAH and either mild-to-moderate or severe genital masculinization-and asked for clinical recommendations. Across timepoints, most participants recommended rearing the newborn as a girl, that parents (in consultation with physicians) should make surgical decisions, performing early genitoplasty, and disclosing surgical history at younger ages. Several trends were identified: a small, but significant shift toward recommending a gender other than girl; recommending that adolescent patients serve as the genital surgery decision maker; performing genital surgery at later ages; and disclosing surgical details at younger ages. This is the first study assessing physician recommendations across two decades. Despite variability in the recommendations, most experts followed CAH clinical practice guidelines. The observation that some of the emerging trends do not align with expert opinion or empirical evidence should serve as both a cautionary note and a call for prospective studies examining patient outcomes associated with these changes.

A Rare Case of Giant Bilateral Adrenal Myelolipomas in a Patient With Classical Congenital Hyperplasia.

Congenital adrenal hyperplasia (CAH) is caused by genetic defects in the enzymes involved in cortisol biosynthesis in the adrenal gland and, in more than 90% of cases, due to a deficiency in the 21-hydroxylase enzyme. Classical CAH due to 21-hydroxylase deficiency is a severe form of the disease that presents with cortisol deficiency and is further categorized into salt-wasting or simple-virilizing types. Appropriate steroid replacement has been shown to effectively treat patients with classical CAH and prevent complications. Individuals who receive inadequate treatment or fail to comply with their prescribed steroid hormone regimen are susceptible to the development of adrenal myelolipomas. Myelolipomas are benign tumors composed of both adipose and hematopoietic tissues. While documented cases of adrenal myelolipomas exist in medical literature, instances of large bilateral myelolipomas remain exceedingly rare. This case report highlights a 40-year-old female patient with a known history of classical congenital adrenal hyperplasia who presented with unusually large bilateral adrenal myelolipomas. A diagnostic CT scan of the abdomen and pelvis revealed a 13.4 x 10.8 cm myelolipoma on the left adrenal gland and a 10 x 8.6 cm myelolipoma on the right adrenal gland. Prior to her presentation, the patient experienced recurrent nausea and vomiting, along with left upper quadrant pain, over five months. Hormonal assessments indicated significantly elevated serum androgen levels, suggesting inadequate management of her CAH. In this report, we present a rare case of symptomatic bilateral large adrenal myelolipomas, underscoring the significance of adhering to treatment regimens, diagnostic assessments, and management for adrenal myelolipomas in individuals diagnosed with CAH.

A Case of 17α-hydroxylase/17,20-lyase Deficiency Diagnosed at 45 Years of Age with Hyperaldosteronism.

17α-hydroxylase deficiency is a type of congenital adrenocortical hyperplasia that is typically diagnosed in childhood or adolescence. It manifests as hypertension with gonadal dysfunction as the primary symptom. We herein report 17α-hydroxylase/17,20-lyase deficiency (17OHD) diagnosed at the age of 45 years. The patient presented with hypertension, irregular menstruation, and hyperaldosteronism. The clinical manifestations of 17OHD vary based on the specific variant pattern of CYP17A1. In this case, the variant was c.157_159 TCC del p. Phe53del, which has been frequently reported in Japan. The enzymatic deficiency due to this variant is partial, leading to a delay in making a correct diagnosis.

Landscape of congenital adrenal hyperplasia cases in adult endocrinology clinics of Türkiye-a nation-wide multicentre study.

BACKGROUND AND AIMS: Congenital adrenal hyperplasia (CAH) is a group of disorders that affect the production of steroids in the adrenal gland and are inherited in an autosomal recessive pattern. The clinical and biochemical manifestations of the disorder are diverse, ranging from varying degrees of anomalies of the external genitalia to life-threatening adrenal insufficiency. This multicenter study aimed to determine the demographics, biochemical, clinical, and genetic characteristics besides the current status of adult patients with CAH nationwide. METHODS: The medical records of 223 patients with all forms of CAH were evaluated in the study, which included 19 adult endocrinology clinics. A form inquiring about demographical, etiological, and genetic (where available) data of all forms of CAH patients was filled out and returned by the centers. RESULTS: Among 223 cases 181 (81.16%) patients had 21-hydroxylase deficiency (21OHD), 27 (12.10%) had 11-beta-hydroxylase deficiency (110HD), 13 (5.82%) had 17-hydroxylase deficiency (17OHD) and 2 (0.89%) had 3-beta-hydroxysteroid-dehydrogenase deficiency. 21OHD was the most prevalent CAH form in our national series. There were 102 (56.4%) classical and 79 (43.6%) non-classical 210HD cases in our cohort. The age of the patients was 24.9 ± 6.1 (minimum-maximum: 17-44) for classical CAH patients and 30.2 ± 11.2 (minimum-maximum: 17-67). More patients in the nonclassical CAH group were married and had children. Reconstructive genital surgery was performed in 54 (78.3%) of classical CAH females and 42 (77.8%) of them had no children. Thirty-two (50.8%) NCAH cases had homogenous and 31 (49.2%) had heterogeneous CYP21A2 gene mutations. V281L pathological variation was the most prevalent mutation, it was detected in 35 (55.6%) of 21OHD NCAH patients. CONCLUSION: Our findings are compatible with the current literature except for the higher frequency of 110HD and 17OHD, which may be attributed to unidentified genetic causes. A new classification for CAH cases rather than classical and non-classical may be helpful as the disease exhibits a large clinical and biochemical continuum. Affected cases should be informed of the possible complications they may face. The study concludes that a better understanding of the clinical characteristics of patients with CAH can improve the management of the disorder in daily practice.

Diurnal 11-ketotestosterone and 17-hydroxyprogesterone saliva profiles in paediatric classical congenital adrenal hyperplasia.

OBJECTIVES: The most suitable biochemical markers for therapy adjustment in patients with congenital adrenal hyperplasia are controversial. 11-Oxygenated androgens are a promising new approach. The objective of this study was to investigate the diurnal rhythm of 11-ketotestosterone in children and adolescents in saliva and to correlate it with salivary 17-hydroxyprogesterone. METHODS: Fifty-one samples of steroid day-profiles from 17 patients were additionally analysed for 11-ketotestosterone, retrospectively. All patients were treated in our university outpatient clinic for paediatric endocrinology between 2020 and 2022. Steroid day-profiles of 17 patients could be examined. The cohort showed a balanced sex ratio. The median age was 13 years. The measurements for 17-hydroxyprogesterone were carried out during routine care by immunoassay. The measurements of 11-ketotestosterone were performed from frozen saliva samples using an implemented in-house protocol for liquid chromatography-tandem mass spectrometry (LC-MS/MS). The most important outcome were the absolute values for 11-ketotestosterone, their diurnal rhythmicity and the correlation with 17-hydroxyprogesterone. RESULTS: Both steroids show a circadian diurnal rhythm. 17-hydroxyprogesterone and 11-ketotestosterone correlate significantly. 11-Ketotestosterone showed a positive correlation with BMI at all times of the day. CONCLUSIONS: 11-Ketotestosterone shows circadian rhythmicity in our cohort and correlates with 17-hydroxyprogesterone. These findings serve as an important basis for prospective research into 11-oxygenated androgens as therapeutic markers in paediatrics. However, 11-ketotestosterone appears to be very dependent on BMI.

Endocrine, cardiac and neuropsychological aspects of adult congenital adrenal hyperplasia.

OBJECTIVE: To investigate the metabolic, cardiovascular, and neuropsychological phenotype, quality of life (QoL), and hormonal regulation in individuals with congenital adrenal hyperplasia (CAH), a group of autosomal recessive disorders characterized by impaired synthesis of cortisol in the adrenal cortex and, if untreated compensatory hyperandrogenism. CAH is associated with an increased cardiovascular and metabolic morbidity, possibly due to overtreatment with glucocorticoids, leading to weight gain, insulin resistance, and metabolic syndrome. DESIGN, PARTICIPANTS, MEASUREMENTS: Thirty-seven individuals with CAH and 33 age- and sex-matched controls were evaluated at a single centre at Aarhus University Hospital with echocardiography, electrocardiogram, 24-h blood pressure, biochemistry, anthropometrics, and autism spectrum, anxiety, depression, personality, cognitive failures, and QoL were assessed using questionnaires. RESULTS: CAH individuals had lower height than controls (170.5 vs. 182.9 cm in males and 160.2 vs. 170.1 cm in females, p < 0.01). Compared with female controls, females with CAH had higher haemoglobin (8.8 vs. 8.2 mmol/L, p = 0.003) and BMI (29.7 vs. 25.5 kg/m2, p = 0.006), reduced insulin sensitivity (HOMA-IR): 2.7 vs. 1.9, p = 0.018), prolonged E-wave deceleration time (193 vs. 174 cm, p = 0.015), and E/é ratios (5.4 vs. 4.5, p = 0.017), and lower self-reported QoL. Males with CAH had more cognitive complaints (p = 0.034) and higher autistic scores (19.9 vs. 14.9; p = 0.068) compared with male controls. More individuals with CAH than controls reported writing problems. CONCLUSION: A sex-specific comorbidity profile is evident in CAH, with females presenting with decreased metabolic and overall self-reported health, whereas males with CAH presented with increased cognitive complaints and autistic traits.

Presentation and Care for Children with Peripheral Precocious Puberty.

Peripheral precocious puberty (PPP) refers to the early onset of sexual maturation that is independent of central nervous system control. The extensive differential diagnosis includes congenital and acquired causes. Presenting features depend on which class of sex steroids is involved, and diagnosis rests on hormonal and, if indicated, imaging and/or genetic studies. Effective treatment exists for nearly all causes of PPP. Ongoing research will advance our therapeutic armamentarium and understanding of the pathophysiologic basis of these conditions.

Ovarian reserve and fertility parameters in post-pubertal females with congenital adrenal hyperplasia: a case-control study.

OBJECTIVES: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder characterized by impaired activity of the enzyme required for cortisol and aldosterone production, resulting in increased adrenal androgen synthesis. Factors affecting fertility in CAH patients include ambiguous genitalia and their complications, excessive androgen secretion, adrenal progesterone hypersecretion, and various psychosocial factors. Serum anti-Müllerian hormone (AMH) level is used to assess ovarian reserve in women. A few data on serum AMH levels in CAH patients are available in the literature. The aim of the study was to evaluate ovarian reserve in a group of post-menarche females diagnosed with CAH by measuring serum AMH level and assessing the number of antral follicles sonographically. METHODS: A case-control study was conducted on 17 post-pubertal CAH females and 17 age-matched healthy female controls; the mean age of the patient group was 15.09 ± 3.55 years ranging from 11 to 24 years, while the mean age of the control group was 16.04 ± 3.72 years ranging from 12 to 25 years, the mean post-menarchal age of the patients group was 3.29 ± 1.37 years ranging from 1 to 6 years while the mean post-menarchal age of the control group was 4.13 ± 1.62 years ranging from 1 to 9 years. The degree of hirsutism was compared between the two groups according to the modified Ferriman-Gallwey score, clitoral length was assessed using a digital caliber. Serum levels of adrenal androgens in addition to basal levels of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and serum AMH were measured in both groups. RESULTS: Patients had smaller uterine volumes, and smaller ovarian volumes but a comparable number of antral follicles and comparable serum AMH levels relative to controls. CONCLUSIONS: Good compliance with treatment in patients with CAH results in good hormonal control, low risk of PCOS, good fertility parameters, and a good ovarian reserve.

Increased risk of nephrolithiasis: an emerging issue in children with congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

PURPOSE: To investigate the incidence of nephrolithiasis in a cohort of children with congenital adrenal hyperplasia (CAH), and to study if there is an association with the metabolic control of the disease. METHODS: This study was designed as a multicenter 1 year-prospective study involving 52 subjects (35 males) with confirmed molecular diagnosis of CAH due to 21-hydroxylase deficiency (21-OHD). Each patient was evaluated at three different time-points: T0, T1 (+6 months of follow-up), T2 (+12 months of follow up). At each follow up visit, auxological data were collected, and adrenocorticotrophic hormone (ACTH), 17-hydroxyprogesterone (17-OHP), Δ4-androstenedione, dehydroepiandrosterone sulfate (DHEAS) serum levels, and urinary excretion of creatinine, calcium, oxalate and citrate were assayed. Moreover, a renal ultrasound was performed. RESULTS: The incidence of nephrolithiasis, assessed by ultrasound was 17.3% at T0, 13.5% at T1 and 11.5% at T2. At T0, one subject showed nephrocalcinosis. In the study population, a statistically significant difference was found for 17-OHP [T0: 11.1 (3.0-25.1) ng/mL; T1: 7.1 (1.8-19.9) ng/mL; T2: 5.9 (2.0-20.0) ng/mL, p < 0.005], and Δ4-androstenedione [T0: 0.9 (0.3-2.5) ng/mL; T1: 0.3 (0.3-1.1) ng/mL; T2: 0.5 (0.3-1.5) ng/mL, p < 0.005] which both decreased over the follow up time. No statistically significant difference among metabolic markers was found in the group of the subjects with nephrolithiasis, even if 17-OHP, DHEAS and Δ4-androstenedione levels showed a tendency towards a reduction from T0 to T2. Principal component analysis (PCA) was performed to study possible hidden patterns of associations/correlations between variables, and to assess the trend of them during the time. PCA revealed a decrease in the amount of the variables 17-OHP, Δ4-androstenedione, and ACTH that occurred during follow-up, which was also observed in subjects showing nephrolithiasis. CONCLUSIONS: our data demonstrated that children affected with 21-OHD can be at risk of developing nephrolithiasis. Additional studies are needed to clarify the pathogenesis and other possible risk factors for this condition, and to establish if regular screening of kidney ultrasound in these patients can be indicated.

Outcomes of one-stage feminizing genitoplasty in children with congenital adrenal hyperplasia and severe virilization.

PURPOSE: To present our surgical experience and outcomes in congenital adrenal hyperplasia (CAH) patients with severe virilization using a combined technique of total urogenital mobilization (TUM) and a modified pull-through vaginoplasty to perform a safe and effective one-stage feminizing genital reconstruction for these children. METHODS: Fourteen CAH patients with severe virilization, defined by a Prader IV and V rating of the external genitalia, underwent TUM followed by a limited vaginal pull-through procedure from June 2016 to December 2020. Postoperative anatomical and cosmetic outcomes, and urinary continence, were evaluated. RESULTS: Out of the 14 cases in this study, 8 were classified as prader IV and 6 as Prader V. The median age at surgery was 11 months (range 6-36 months), and the mean urethral length was 1.4 cm (range 1.2-1.8 cm). The median follow-up period was 4 years. Our cosmetic outcomes were good in 11 (78.5%), satisfactory in 2, and poor in one case. All patients achieved age-appropriate toilet training without urinary incontinence. CONCLUSION: Adopting our surgical approach of TUM with modified pull-through vaginoplasty has simplified feminizing surgical reconstruction in CAH cases with severe genital atypia and a very high vaginal confluence with short urethral length, yielding adequate introitus with good anatomical and cosmetic appearance and adequate urinary continence outcomes.

Unveiling the spectrum: A cross-sectional exploration of hirsutism causes in women.

Background and Objective: Hirsutism is a common endocrine disorder and its etiology varies from benign and idiopathic disorders to serious malignant diseases. Hirsutism creates negative impact on quality of life and considerable effects on fertility. Our objective was to determine the various causes of hirsutism in women presenting at two endocrine clinics. Method: This cross-sectional study was conducted at Baqai Institute of Diabetology and Endocrinology, Karachi and at Jinnah hospital, Lahore from August 2020 to December 2021 women between 12-45 years of age with complains of hirsutism were included in the study. Severity of Hirsutism was evaluated using modified Ferriman-Gallwey score (FG). Patients with modified FG score of 8 or more were considered having hirsutism. Results: The study had 113 patients with a mean age of 15.50+7.29 years with 89% having moderate hirsutism (FG score 16-25). Polycystic ovaries was the most common cause of hirsutism. Common sites for hirsutism included back (83%), arms (74%), buttocks (70%), and upper abdomen (47%). High BMI (p-value <0.01) and high Dehydroepiandrosterone levels were positively associated with the severity of hirsutism (p-value of 0.006.). Conclusion: The various causes of hirsutism identified were polycystic ovaries, followed by idiopathic, thyroid dysfunction, congenital adrenal hyperplasia, and hyperprolactinemia; therefore, all women presenting with hirsutism should be evaluated for potential serious and curable etiologies, before embarking on a treatment plan.

High carrier frequency of CYP21A2 gene mutations in Southern India - underscoring the need for genetic testing in Congenital Adrenal Hyperplasia.

PURPOSE: Congenital Adrenal Hyperplasia (CAH) is one of the highly prevalent autosomal recessive endocrine disorders. The majority of CAH cases result from mutations in the CYP21A2 gene, leading to 21-hydroxylase deficiency. However, with the pseudogene-associated challenges in CYP21A2 gene analysis, routine genetic diagnostics and carrier screening in CAH are not a part of the first-tier investigations in a clinical setting. Furthermore, there is a lack of data on the carrier frequency for 21-OH deficiency. Therefore, this study is aimed at investigating the carrier frequency of common pseudogene derived CYP21A2 mutations in Southern India. METHODS: Recently, a cost-effective Allele-specific PCR based genotyping for CYP21A2 hotspot mutations has been demonstrated to be a highly specific and sensitive assay at the authors' center. Leveraging this approach, a total of 1034 healthy individuals from South India underwent screening to identify the carrier frequency of nine hotspot mutations in the CYP21A2 gene. RESULTS: In this study, it was observed that 9.76% of the subjects were carriers for one or more of the nine different CYP21A2 mutations. Among the carriers, the most common was the large 30 kb deletion, followed by II72N, E6 CLUS, and I2G mutations. CONCLUSION: We have identified a high prevalence of CYP21A2 mutation carriers in Southern India. These findings emphasize the importance of implementing and expanding cost-effective genetic diagnostics and carrier screening throughout India. Such initiatives would play a crucial role in managing the disease burden, enabling early intervention, and establishing guidelines for CAH newborn genetic screening in the country. This study represents the first carrier screening data on CYP21A2 hotspot mutations from India and is the largest study conducted till date in this context.
