OBJECTIVE: To investigate the clinical characteristics, steroid hormone profiles, and genetic variants in two female patients with Non-classic adrenal hyperplasia (NCAH). METHODS: Clinical data and samples were collected from two patients who had visited Huaian Maternal and Child Health Care Hospital Affiliated to Medical College of Yangzhou University on September 27, 2022 and June 25, 2023, respectively, with an initial diagnosis of Polycystic ovary syndrome (PCOS) and suspected NCAH. Seven steroid hormones in dried blood spots were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Single base variants and repeat/deletions in the CYP21A2 gene were analyzed by using a classic congenital adrenal hyperplasia (CAH) gene assay, and 10 related genes were analyzed by third-generation sequencing (TGS) should the variants be unclear. This study has been approved by the Medical Ethics Committee of the hospital (Ethics No.: 2025003). RESULTS: Patient 1 was a 14-year-old girl, and patient 2 was a 23-year-old woman with insulin resistance. Both patients had hirsutism, acne, bilateral polycystic ovarian morphology, in addition with significantly elevated serum testosterone by chemiluminescence. The steroid hormone profiles of both patients suggested a significant increase in 17-hydroxyproesterone, normal cortisol and 11-deoxycortisol. Patient 2 additionally showed a significant rise in 21-deoxycortisol. The presentation of both patients was indicative of NCAH, which was also evidenced by their respective medical histories. Sanger sequencing of long fragment PCR amplification combined with multiplex ligation-dependent probe amplification (MLPA) revealed that patient 1 harbored a mild c.92C>T (p.P31L) variant and a severe variant with a large segmental deletion in CYP21A2. Patient 2 was finally confirmed by TGS to carry mild CYP21A2 variants in the 5' untranslated region (5' UTR) promotor region (c.-126C>T, c.-113G>A, c.-110T>C) and a severe c.293-13C/A>G variant. The promotor region variants had resulted in decompression of the long fragment P1X/P2 amplification, leading to homozygous result of Sanger sequencing for c.293-13C/A>G, which in turn halved the amplification signal for the wt-113 SNP probe. In addition, the wtI2G-A probe was enhanced by interference in the MLPA assay. CONCLUSION This study demonstrated that NCAH should be excluded when PCOS is accompanied by a significant increase in serum testosterone, that mass spectrometry of steroid hormone profiles containing 17-hydroxyprogesterone is useful for the detection of NCAH, and that TGS is advantageous in confirming the diagnosis of NCAH when compared with conventional genetic testing methods.

Introduction: Steroid cell tumors are rare sex cord-stromal tumors, accounting for <0.1% of ovarian neoplasms. Extraovarian steroid cell tumors are exceptionally rare, often androgensecreting, and pose significant diagnostic challenges. Early recognition is essential to prevent prolonged morbidity from hyperandrogenism. Case: A 60-year-old female, 15 years after total hysterectomy and bilateral salpingo-oophorectomy for a large ovarian mass with massive ascites, presented with deranged liver function tests on routine follow-up. Ultrasonography and computed tomography imaging revealed multiple hypervascular lesions in the liver, retroperitoneum, and peritoneum, suggestive of metastatic disease, with normal-appearing adrenal glands. Biopsy of a liver lesion demonstrated a metastatic neoplasm with morphology and immunoprofile favoring a steroid cell tumor. However, metastasis from the adrenal cortex or an ovarian primary could not be excluded. Given the prior bilateral oophorectomy, metastatic adrenocortical carcinoma was initially suspected, prompting endocrine evaluation. Further history revealed a 1-year history of progressive virilization, including increased facial hair and frontal balding. Hormonal studies demonstrated elevated testosterone (12.2 mmol/L and reference range 0.1–1.42) and dehydroepiandrosterone sulfate (15.9 µmol/L and reference range 0.510–5.560) and the adrenocorticotropic hormone level of 11.7 pmol/L (reference range 1.60–13.9) with suppressed gonadotrophins. Additional workup for catecholamine, cortisol, and aldosterone excess was unremarkable. The discordance between androgen excess and normal adrenal imaging, despite absent ovarian tissue, suggested an extraadrenal androgen-secreting steroid cell tumor. A second histopathology review and multidisciplinary discussion with radiology, gynecologic oncology, and pathology teams were undertaken. As the disease was deemed inoperable, repeat retroperitoneal lesion biopsy confirmed metastatic steroid cell tumor and guided palliative chemotherapy. She was subsequently referred to gynecologic oncology for systemic chemotherapy. Conclusion Extra-adrenal steroid cell tumors, though rare, should be considered in patients with hyperandrogenism long after bilateral oophorectomy, especially when adrenal imaging is normal. Multidisciplinary evaluation and repeat biopsy are often crucial for establishing the diagnosis and guiding treatment.

Introduction: Polycystic ovary syndrome (PCOS) is the most common cause of hyperandrogenism in women of reproductive age. However, several endocrine disorders, particularly Cushing disease (CD), can closely mimic the clinical, biochemical, and radiological features of PCOS. This overlap may lead to misdiagnosis and delayed recognition of hypercortisolism, with significant metabolic and reproductive consequences. Case: We report a 24-year-old female with young-onset diabetes mellitus who was referred for endocrine co-management during admission for recurrent mons pubis and labial abscesses with poorly controlled glycemia. She had a 5-year history of progressive hirsutism, oligomenorrhoea, scalp hair loss, significant weight gain, and insulin resistance, and had previously been labelled as having PCOS during adolescence, with subsequent default of follow-up. On examination, she was obese (body mass index 33 kg/ m²) with plethoric facies, acanthosis nigricans, proximal myopathy, and hirsutism (Ferriman–Gallwey score 10), without overt virilization or acromegalic features. Biochemical evaluation demonstrated severe hyperandrogenism with markedly elevated total testosterone (7.05 nmol/L), suppressed gonadotropins, and adrenocorticotropic hormone (ACTH)-dependent hypercortisolism. Cortisol failed to suppress on low-dose dexamethasone testing, and 24-hour urinary free cortisol was markedly elevated (>4,900 nmol/24 h). Pelvic ultrasonography and computed tomography imaging showed polycystic ovarian morphology without evidence of an ovarian mass. Pituitary magnetic resonance imaging revealed a small right-sided pituitary microadenoma measuring 2.6 × 3.7 mm. Inferior petrosal sinus sampling demonstrated a central-to-peripheral ACTH gradient with adequate prolactin ratios, confirming pituitary CD. Conclusion This case highlights how Cushing disease can closely mimic PCOS, including polycystic ovarian morphology and hyperandrogenism. Progressive symptoms, severe biochemical androgen excess, and marked insulin resistance should prompt evaluation for secondary causes of hyperandrogenism, particularly hypercortisolism, to avoid delayed diagnosis and prolonged morbidity.

OBJECTIVE: To investigate the clinical therapeutic effect of Rendu Tongtiao acupuncture (acupuncture for regulating and improving the circulation of the conception and governor vessels) on hyperandrogenism (HA) in polycystic ovary syndrome (PCOS) with kidney-yin deficiency induced fire hyperactivity. METHODS: A total of 80 PCOS-HA patients were selected and randomly divided into an observation group and a control group, 40 cases in each group. In the control group, ethinylestradiol and cyproterone acetate tablets were administered orally,2 mg each time, once daily and for 21 consecutive days as one menstrual cycle. In the observation group, Rendu Tongtiao acupuncture was delivered at Qihai (CV6), Zhongwan (CV12), Guanyuan (CV4), Zhongji (CV3), Mingmen (GV4), Yaoyangguan (GV3), etc. once daily till ovulation, which was taken as the treatment session of one menstrual cycle. The treatment was completed after 3 menstrual cycles in each group. Before and after treatment, the serum levels of testosterone (T), dihydrotestosterone (DHT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), sex hormone-binding globulin (SHBG), and the scores of acne and hirsutism were compared in the two groups; besides, menstrual recovery rate, ovulation recovery rate, basic body temperature (BBT) biphasic rate and clinical effect were compared between the two groups. RESULTS: Compared with those before treatment, the levels of T, DHT, LH and PRL, as well as the scores of acne and hirsutism were reduced in the two groups after treatment (P<0.05), and the levels of FSH and SHBG were increased (P<0.05). After treatment, the levels of T, DHT, LH and PRL, as well as the scores of acne and hirsutism in the observation group were lower than those in the control group (P<0.05); and FSH and SHBG were higher (P<0.05). After treatment, the menstrual recovery rate and ovulation recovery rate, as well as BBT biphasic rate in the observation group increased in comparison with the control group (P<0.05). The total effective rate was 97.5% (39/40) in the observation group, which was higher than 82.4% (33/40) of the control group (P<0.05). CONCLUSION Rendu Tongtiao acupuncture can effectively regulate the secretion of hormones, alleviate the clinical symptoms of HA, and accelerate the recovery of menstruation and natural ovulation in patients with PCOS-HA of kidney-yin deficiency induced fire hyperactivity .

OBJECTIVE: To investigate the clinical phenotype and genetic diagnosis process of fetuses with 21 hydroxylase deficiency (21-OHD) caused by compound heterozygous variant of the CYP21A2 gene . METHODS: A fetus who was diagnosed at Taizhou Hospital in Zhejiang Province on December 4, 2020 due to unclear characteristics of external genitalia on ultrasound was selected as the study subject. Chromosome copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) were performed on amniotic fluid samples. Candidate variants were validated by Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA), and short tandem repeat (STR) analysis was used to exclude maternal blood contamination. The pathogenic mechanism of the variants was further explored. The procedure followed by this study was approved by the Medical Ethics Committee of Taizhou Hospital (Ethics No.: K20201009). RESULTS: The MRI examination of the fetal external genitalia showed thickening of labia minora and enlargement of the clitoris. The CNV-seq results of the fetus showed no significant abnormality. The WES results showed that the fetus had a homozygous c.293-13C>G variant in the CYP21A2 gene (NM-000500.9). STR testing excluded maternal blood contamination. Sanger sequencing verified the presence of heterozygous c.293-13C>G variant of the CYP21A2 gene in the fetus and its mother, while its father did not detect this mutation. Further MLPA testing results showed that the fetus and its father had heterozygous deletion (I2G-C locus) mutations in exon 1~7 of the CYP21A2 gene. Based on the "Standards and Guidelines for Interpretation of Sequence Variants" jointly developed by the American College of Medical Genetics and Genomics (ACMG) and the Association for Molecular Pathology (AMP), both variants of the CYP21A2 gene carried by the fetus were predicted to be pathogenic. According to the imaging and genetic testing results of the external genitalia of the fetus, the fetus was prenatally diagnosed as 21-OHD caused by the CYP21A2 gene variant. Follow-up after prenatal diagnosis showed that the couple had opted to terminate the pregnancy at a local hospital at 31⁺ weeks of gestation, and the clinical phenotype of the abortion fetus was consistent with the imaging and molecular genetic diagnosis. CONCLUSION The imaging features of this fetus are suspected to be congenital adrenal hyperplasia (CAH). Combined with WES, Sanger sequencing, and MLPA testing results, the fetus was diagnosed with 21-OHD caused by compound heterozygous variants of the CYP21A2 gene, which provided a basis for prenatal diagnosis.

BACKGROUND

Polycystic ovarian syndrome (PCOS) is a common gynecologic endocrine disorder affecting between 2.2% and 26% of the population. It is typically characterized by hirsutism and signs of ovulatory dysfunction. Hirsutism is defined as the presence of excess body or facial terminal hair growth in females, following a male-like pattern. It is diagnosed using visual assessment methods, such as the modified Ferriman–Gallwey (mFG) scoring system, and biochemical tests, including measurements of total testosterone (tT) and the free androgen index (FAI).

The general objective of the study is to identify the correlation of visual scoring with the biochemical evaluation of hirsutism. Specific objectives include (1) to describe the visual and biochemical scores of hirsutism in PCOS patients and (2) to determine a cutoff score for the visual scoring of hirsutism among Filipinos.

This is a cross-sectional study done in a tertiary hospital. Ethical approval was obtained for this study. Patients who satisfied the inclusion criteria were included in the study. Age, height, weight, body mass index (BMI), and OB score were noted. Visual scoring for hirsutism using the mFG scoring system was performed. Blood extraction was done for testosterone and sex hormone-binding globulin tests. FAI was then computed and correlated with the mFG scores.

A total of 52 patients were identified. A positive correlation is noted between the mFG with testosterone and FAI. A positive correlation was also noted between the BMI with testosterone and FAI. An mFG value of >4 is an acceptable cutoff for Filipinos.

The study showed as the mFG score increases, FAI and tT levels also increase. It was also noted that as BMI increases, the FAI and tT levels are also expected to increase. It can also be concluded that a lower mFG cutoff value, >4, is applicable for Filipinos.

OBJECTIVES: To study the clinical and genetic characteristics of children with congenital adrenal hyperplasia (CAH). METHODS: Clinical data, laboratory findings, and genetic test results of 63 children diagnosed with CAH at Henan Children's Hospital from January 2017 to December 2024 were retrospectively reviewed. RESULTS: Of the 63 patients, the mean age at the first visit was (21 ± 14) days; 29 (46%) were of male sex and 34 (54%) were of female sex. The predominant clinical manifestations were poor weight gain or weight loss (92%, 58/63), poor feeding (84%, 53/63), skin hyperpigmentation (83%, 52/63), and female external genital anomalies (100%, 34/34). Laboratory abnormalities included hyponatremia (87%, 55/63), hyperkalemia (68%, 43/63), metabolic acidosis (68%, 43/63), and markedly elevated 17-hydroxyprogesterone (92%, 58/63), testosterone (89%, 56/63), and adrenocorticotropic hormone (81%, 51/63). Among 49 patients who underwent genetic testing, CYP21A2 variants were identified in 90% (44/49), with c.293-13A/C>G (33%, 30/91) and large deletions/gene conversions (29%, 26/91) being the most frequent; STAR (8%, 4/49) and HSD3B2 (2%, 1/49) variants were also detected. Following hormone replacement therapy, electrolyte disturbances were corrected in 57 cases, with significant reductions in 17-hydroxyprogesterone, adrenocorticotropic hormone, and testosterone levels (P<0.001). CONCLUSIONS CAH presenting in neonates or young infants is characterized by electrolyte imbalance, external genital anomalies, and abnormal hormone levels. Genetic testing enables definitive subtype classification; in CYP21A2-related CAH, c.293-13A/C>G is a hotspot variant. These findings underscore the clinical value of genetic testing for early diagnosis and genetic counseling in CAH. Citation:Chinese Journal of Contemporary Pediatrics, 2025, 27(11): 1367-1372.

OBJECTIVE: To assess the diagnostic efficiency of long-read sequencing (LRS) for the determination of CYP21A1P/CYP21A2 and TNXA/TNXB fusion genotypes among children with 21-hydroxylase deficiency (21-OHD) and explore their clinical characteristics. METHODS: LRS sequencing was carried out on 30 children diagnosed with 21-OHD at the Department of Endocrinology, Fujian Children's Hospital between November 2022 and September 2023 by clinical symptoms or conventional Sanger sequencing combined with multiple ligation-dependent probe amplification (MLPA). The results of the two methods were compared. Clinical data of the children were collected and analyzed. This study has been approved by the Medical Ethics Committee of the Fujian Children's Hospital (Ethic No. 2022ETKLR10024). RESULTS: Of the 30 children with 21-OHD, 11 (36.7%) were found to carry CYP21A1P/CYP21A2 and TNXA/TNXB fusion genes by LRS. The most common type of fused CYP21A1P/CYP21A2 gene was CH-1 (72.7%), and 1 (3.3%) was found to harbor TNXA/TNXB CH-1. Eleven cases (36.7%) were found to carry large deletions by Sanger sequencing combined with MLPA, with the most common one being CYP21A2 exons 1-3 del (72.7%), which was followed by CYP21A2 exons 1-7 del (18.2%). Follow up of 11 patients carrying a fusion gene revealed that 6 were sale wasting (SW) types, 5 were simple virilizing (SV) types, whilst no non-classical (NC) type was found. Four girls had presented with central precocious puberty (CPP). One child carrying TNXA/TNXB CH-1 had presented with CAH-X syndrome. CONCLUSION Compared with Sanger sequencing combined with MLPA detection method, LRS sequencing was able to differentiate the subtypes of CYP21A1P/CYP21A2 and TNXA/TNXB fusion genes, pinpoint the breakpoints of the deletions, and directly determine the cis-trans position without the need to analyze the genotype of the pedigree members, which has provided a reliable method for the typing of 21-OHD. As some fusion genes may retain 21-hydroxylase activity, female carriers may have a higher incidence of CPP.

Congenital Adrenal Hyperplasia and Turner Syndrome are not very rare diseases. However, their combination may be confounding. Presented here is a case of a 54 year old nulligravid, with primary amenorrhea, short stature, absent breast development, hirsutism, signs of virilization, and clitoromegaly who came in due to hypogastric pain and an enlarging palpable hypogastric mass. Diagnostic procedures and surgical management are discussed.

The majority of patients with congenital adrenal hyperplasia (CAH) present with a deficiency of 21-hydroxylase or 11-beta-hydroxylase, which account for 90% and 7% of cases, respectively. However, CAH due to 17α-hydroxylase deficiency (17OHD) is an extremely rare form of CAH (<1% of all CAH cases) that leads to a deficiency of cortisol and sex steroids, along with features of aldosterone excess. This is a case of a 51-year-old single female who was referred to us for the evaluation of new-onset hypertension and hypokalaemia of one-year duration. She was born out of a second-degree consanguineous marriage and reared as a female. She was diagnosed to have testicular feminization syndrome when she presented with a history of primary amenorrhea, absence of secondary sexual characteristics, and bilateral labial swellings at pubertal age. Subsequently, she underwent gonadectomy at the age of 16. Due to the presence of hypertension, metabolic alkalosis and bilaterally enlarged adrenals on CT scan, 46, XY disorders of sexual development (DSD) was considered. A karyotype confirmed the presence of 46, XY chromosomal sex, and genetic analysis revealed a mutation in the CYP17A1 gene, thus confirming the diagnosis of 17a-hydroxylase deficiency.
