Context: DSD represent a wide range of conditions presenting at different ages to many health professionals with several backgrounds. Establishing a correct diagnosis is essential for appropriate management. Objective: To amplify the understanding of the first clinical presentation, prevalence, and gender change of Brazilian DSD subjects. Design: A retrospective, observational cohort study of all DSD subjects referred to a DSD multi-professional team over 41 years (from 1980 to 2021). Participants: 696 subjects.Outcome Measures: Data included DSD diagnosis, sex assignment, age at diagnosis, gender change, clinical presentation, and phenotypic features. Results: Subjects presented at prepubertal, post-pubertal, and adult age, usually with atypical genitalia, undescended testes, or primary amenorrhea. Amongst the three major DSD categories, sex chromosome DSD was diagnosed in 264 subjects (135 with 45,X karyotype); 101 are mosaics (45,X/46,Xi(Xq) and three chimerism (all ovotesticular DSD). Among the 4 ovotesticular DSD subjects, 3 were raised as females and 1 as male, no gender changes occurred in this group. Thirteen chromosome DSD patients with Y material were assigned as male and two female-assigned patients changed their gender. 258 subjects have 46,XY DSD (69 unknown DSD, 64 gonadal dysgenesis, 36 5-αRD2 deficiency, 18 17β-HSD3 deficiency, 11 17α-hydroxylase deficiency, 9 Leydig cell hypoplasia, 25 CAIS, 18 PAIS, 8 AMH defects). Among the 192 XY subjects with atypical genitalia, the sex of rearing was female in 89 (46%) and gender change from female to male occurred in 13%, most in 5 αRD2 (45%) followed by 17β-HSD3 (33%) deficiency. Among those reared as male, only 2.9% changed their gender. 46,XX DSD was diagnosed in 178 patients. Congenital adrenal hyperplasia-CAH (most 21-hydroxylase deficiency) was diagnosed in 123 (115 female-assigned). Among CAH, gender change from female to male occurred in 6 cases, of which most have VS form (5/6; p=.004), a late beginning of treatment ( & gt;2 ys old), and poor compliance. In the remaining 55 with 46,XX DSD, 24 have ovotesticular DSD (all with atypical genitalia), 16 have 46,XX testicular DSD (seven with atypical genitalia). Among the ovotesticular subjects, 14 were reared as male and ten as female, and gender change occurred in 4 cases (3 from female to male). The diagnosis was not established in twelve 46,XX DSD patients (all with atypical genitalia, three with syndromic features). One patient has aromatase deficiency, one POR deficiency, and one glucocorticoid resistance syndrome. Conclusion: gender change from female to male mainly occurred among subjects with 46,XY DSD, particularly in those with 5 αRD2 and 17β-HSD3 deficiency, suggesting that male sex assignment is desirable in patients with these diagnoses. Among 46,XX DSD, the VS form of CAH, a late start of treatment, and poor compliance were implicated in female-to-male gender change. Presentation: Thursday, June 15, 2023

Introduction: MEN-1 is a rare, autosomal dominant syndrome that occurs due to a pathogenic variant of MEN1. The incidence of insulinoma in MEN-1 is relatively rare. 4-6% of patients with insulinoma will develop MEN-1. Unlike sporadic insulinomas that usually develop after the age of 40, MEN-associated insulinoma usually occur before 40 years of age and even sometimes before 20. CASE REPORT: A 26-year-old male patient had a 3-year history of Whipple's triad associated with significant weight gain with a body mass index (BMI) of 33 kg/m² to 58 kg/m² during this period. His father has a metastatic carcinoid tumor, being treated with palliative chemotherapy. Laboratory tests at the time of hypoglycemia were: blood glucose 42mg/dL (RV 75-99), insulin 39 mU/L (RV & lt; 3) and C-peptide 11.6 ng/dL (RV & lt; 0.2). Magnetic resonance imaging (MRI) of pancreas showed 3 hypervascular nodules, the largest in the tail, measuring 3.3 cm, with neuroendocrine characteristics. Distal pancreatectomy, splenectomy and lymphadenectomy were indicated. After surgery, the episodes of hypoglycemia disappeared, with a weight loss of 25 kg. He required postoperative metformin, with satisfactory glycemic control. During the investigation, a prolactinoma was diagnosed (pituitary MRI, which showed a 4 mm adenoma, prolactin 56ng/mL (LR & lt; 25) and hypogonadotrophic hypogonadism), and cabergoline 0.25 mg/week was started. In addition, diagnosis of mild primary hyperparathyroidism (PTH 188 pg/mL and calcium 10.4mg/dL). Parathyroid scintigraphy with 99mTc-MIBI showed increased uptake in the right lower parathyroid. Genetic testing was performed by Next Generation Sequence (NGS) of the MEN1 gene, which was positive for the pathogenic variant c.825-2A & gt;G in heterozygosis in intron 5. A molecular study was performed on the patient's father and sister, which identified the same pathogenic allelic variant in both. Conclusion: We described a rare case of MEN-1 whose first manifestation was insulinoma. Presentation: Thursday, June 15, 2023

Introduction: Children classified as idiopathic short stature (ISS) may have a monogenic cause that can explain their growth disorder. In this context, genetic tests emerge as a new diagnostic tool. Objectives: To determine the usefulness of WES for the genetic investigation of children with ISS. Patients and Methods: We sequentially enrolled 95 children with ISS without previous genetic testing, except for karyotyping for girls. In WES analysis, we prioritized rare variants (MAF & lt;0.001), classified as loss-of-function (LoF) or missense predicted to be deleterious on in silico predictions. All variants were categorized according to ACMG/AMP criteria. We analyzed genes previously associated with growth disorders. CNV analysis was performed based on WES data; additionally, MLPA for SHOX was performed to assess deletion in regulatory regions. In positive cases, we carry out segregation in the family. Results: Our cohort was characterized by male preponderance (67%), markedly short stature (height SDS -2.6±0.7, 20% with height SDS & lt;-3), and in 48% of cases, at least one of the parents have short stature. We identified 12 pathogenic or likely pathogenic (P/LP) variants by WES, including two gene deletions (SHOX and PTHLH) and 10 point mutations in ACAN (2x), IHH, PRKG2, LTBP3, ERF, THRA, GHR, PTPN11, and NF1. Additionally, two deletions involving the regulatory region of the SHOX gene were identified by MLPA. One patient had two P/LP alterations, totaling a diagnostic yield of 13.7% (12.6% if only WES results were considered). It is noteworthy that in addition to genes already associated with ISS (ACAN, SHOX, IHH, GHR, PTPN11, NF1), we observed a greater diversity of genes, including resistance to thyroid hormones (THRA) and milder forms of skeletal dysplasia (LTBP3, PTHLH, PRKG2). All but one of the variants were in the heterozygous state, including two de novo variants and four inherited from a parent with short stature. Fifteen patients have variants of uncertain significance (VUS) in genes already associated with growth disorder: IHH (3x), FGFR3 (2x), NPR2 (2x), LZTR1 (2x), MMP13, COL11A1, COL11A2, EXT2, IGF1R, and WNT5. Furthermore, four patients have variants of interest in new candidate genes (MAU2, MAP3K4, NR2E1, C6ORF136). Conclusion: The diagnostic yield was similar to other studies in children with ISS, but a greater diversity of genetic causes was observed, with those involving growth-plate genes and the RAS-MAPK pathway being more frequent. The large number of VUS highlights the need for further studies and new tools to classify these variants definitively. Presentation: Thursday, June 15, 2023

    Abstract: Sporadic Adrenal Medullary hyperplasia (AMH) has been little described in the literature, being most often diagnosed during a genetic syndrome screening or the evaluation of an adrenal incidentaloma. Case report A 51-year-old female patient presented with progressive attacks of tachycardia, headache, nausea and mild paroxysmal hypertension, which started in December 2020. She had a history of smoking and she also presented Takotsubo syndrome in 2018. She denied other comorbidities. In March 2021, she was submitted to laboratorial testing which demonstrated indeterminate plasma fractionated metanephrines by HPLC/MS: metanephrines 0.3 nmol/L (n & lt; 0.5) and normetanephrines 1.2 nmol/L (n & lt; 0.9) and normal serum chromogranin A level: 82 ng/mL (n & lt;93) by Directed Proteomic. Urinary metanephrines were collected in a spot sample after an adrenergic crisis episode, confirming the biochemical diagnosis: metanephrines 255 mcg/g creatinine (n 30-165), normetanephrine 824 mcg/g creatinine (n 105-375), total 1119 mcg/g creatinine (n 150- 510) by HPLC. She was submitted to an abdominal MRI, which showed bilateral adrenal thickening with medullary predominance with hyperintense sign on T2-weighted images. It was also performed a mIBG I 131 spect and a PET-CT DOTATATO-Galium 68 without abnormal uptakes. A genetic panel by NextGeneration Sequence (NGS) was also carried out for pheochromocytoma/paraganglioma (PHEO/PGL) without pathological findings. The patient underwent laparoscopic left adrenalectomy after the use of alpha and beta blockade for one month, with pathological findings suggestive of adrenal medullary hyperplasia. However, she remained symptomatic after surgery. Once again, new urinary metanephrines in a spot sample were collected after an adrenergic crisis: metanephrines 188 mcg/g creatinine (n 30-165), normetanephrines 1229 mcg/g creatinine (n 105-375), total 1417 mcg/g creatinine (n 150-510) by HPLC, which demonstrated remaining cathecolamine excess. She underwent a contralateral laparoscopic adrenalectomy without surgical complications. An anatomopathological analysis was performed in both adrenals, which confirmed bilateral adrenal medullary hyperplasia without associated PHEO. The patient showed improvement in adrenergic symptoms and normalization of plasma fractionated metanephrines levels postoperatively, currently using hydrocortisone and fludrocortisone for the treatment of adrenal insufficiency. Conclusion Adrenal Medullary hyperplasia is a rare condition, which usually presents in a milder form and is often associated with pheochromocytoma or genetic syndromes. However it should be considered in symptomatic patients without a personal or family history of PHEO/PGL, allowing an early diagnosis and treatment. Presentation: No date and time listed

    Abstract: Carney's complex (CNC) is a rare genetic multiple neoplasia syndrome, with involvement in several systems, among them, acromegaly is a possible condition, according to the literature, seen in about 10% of cases. PPRKAR1A is the most known gene evolved. The genetic origin of 59% of patients with CNC has not yet been elucidated. ClinicalCases A 17-year-old malewithtall stature, withstigmaofgigantism, GH 9.89 ng/ml and IGF-1 1.5 times higher reference value, MRI with pituitary adenoma of 0.7cm. After resection transfenoidal endoscopic (TSE) thepathology of the tumor revealed a pure GH pituitary adenoma. Echocardiogram showed cardiac myxomas. For that reason, a Carney complex was established. In the search for other alterations present in the syndrome, a nodule was found in the right testicle, which after nodulectomy shown a Leydig Cell Tumor. After these findings, we invited all family members to perform screening to identify possible involvement of the CNC. Two brothers, including a twin, and their mother also had stigma of acromegaly, all with pituitary adenoma and laboratorial diagnostic. The two menunderwentTSE surgery reassuring GH secretion by the tumor. The elderly brother had aggressive microcalcilfications in bilateral testicles. After bilateral orchiectomy was diagnosed witha large cell calcifying sertoli cell tumor. The twin brother also had cardiac mixomas and macrocalcifications in testicle but without signs of malignancy. The mother had athyroid ultrasound showing a multinodular goiter and breast lesions also with no signs of malignancy. She also had a pituitary microadenoma,butrefused the surgery and is currently using thesomatostatinanalog. CNC is a multiple neoplasia syndromeusually characteriszed by lentiginosis, multiple neoplasias and signs of endocrine overactivity, particularly Primary Pigmented Nodular Adrenal Disease (PPNAD) and myxomas. It is a rare condition and its prevalence remains unknown. A patogenic allelic variant (PAV) of PRKAR1A is found in 37% of patients with sporadic CNC and more than 70% of patients with familial CNC. To this date, at least 130 different mutations have been described in more than 400 families around the world, distributed across the ten coding exons (PRKAR1A has 11 exons, but exon 1 is non-coding and rarely mutated) and in the adjacent intronic sequences. In 2014, a germline triplication of the exon of PRKACB gene has been identified in pacient who did not harbour a PRKAR1A mutation. In our case, a search of PAV was realized by exome NGS and CG-Array but we found no evidence of variant that can explain the occurence of CNC. Conclusion We describe the follow-up of a family with CNC without PAV identified so far. Presentation: No date and time listed

    Abstract: Primary aldosteronism (PA) is a leading cause of secondary hypertension and harness a much higher cardiovascular risk than essential hypertension. About 30% of PA cases are due the existence of an aldosterone-producing adenoma (APA). Although the current guidelines recommend unilateral laparoscopic adrenalectomy as the standard treatment of APA, some patients might no be suited for the procedure. Clinical Case A 66-year man was referred to our institution following a 14-year history of resistant hypertension. His past history included a stage III chronic kidney disease, type 2 diabetes mellitus, dyslipidemia, obstructive sleep apnea (OSA), hypothyroidism, grade I obesity, and rheumatoid arthritis. Initial tests were consistent with PA: elevated serum aldosterone (26 ng/dL), suppressed plasma renin activity (PRA: 0. 07 ng/ml/H) and a high aldosterone/renin ratio (RAR: 65) with concomitant hypokalemia (3,4 mEq/L). Abdominal CT-scan demonstrated a 11×8 mm left adrenal nodule with an absolute washout of 60%. A diagnosis of an APA was confirmed by an adrenal vein sampling. Since the patient had multiple comorbidities and an unequivocal high surgical risk, laparoscopic adrenalectomy was contraindicated, and pharmacologic treatment was started with spironolactone. Despite the use of high doses of spironolactone, blood pressure (BP) control was not achieved. Moreover, severe side effects were experienced, notably sexual dysfunction and painful gynecomastia. In this setting, a decision for a CT-guided radiofrequency ablation was made. The procedure underwent under general anesthesia and had no adverse events. Three days after the ablation, biochemical analysis demonstrated a significant reduction of aldosterone (10 ng/dL) and RAR (10), whereas the PRA was notably higher (1,45 ng/mL/h). He transitioned from 6 different classes of anti-hypertensives drugs to only one and his blood pressure was well controlled in an appointment 30 days after the procedure. On the other hand, his glomerular filtration rate had decayed from 44 mL/min to 31 mL/h due to a rapid blood pressure control. Despite no changes in anthropometric measures and OSA related symptoms were observed, an expressive reduction in microalbuminuria (191 mg/dL to 28,6 mg/dL) was noticed. Conclusion The CT-guided radiofrequency ablation is a suitable minimally invasive treatment for PA in high surgical risk patients. For patients with high surgical risk and intolerance to clinical treatment, radiofrequency should be offered as an option for treatment in a specialized center. Presentation: No date and time listed

    Abstract: Background: Short stature is the most frequent clinical manifestation in Turner syndrome (TS), occurring in 98% of these patients. Growth hormone was shown to improve adult height in TS patients from diverse genetic backgrounds. However, there are few studies on adult height in TS patients from developing countries, where the diagnosis is frequently delayed. Objective: To compare adult height between GH-treated and untreated TS patients. Patients and methods: 120 GH-treated and 109 GH-untreated TS patients from 3 referral hospitals in Brazil were evaluated. The most common reasons for not treating TS patients with GH were late diagnosis or GH unavailability. Data on karyotype, parents’ height, puberty development and GH treatment were obtained from their medical records. Adult height was determined when growth velocity was inferior to 1cm/year during a minimum follow-up period of 12 months. Results: The frequency of 45,X karyotype was similar between the groups (48.7% vs. 41.9% in GH-treated vs. GH-untreated TS patients, respectively, P= 0.639). GH-treated TS patients started GH therapy at a chronological age (CA) of 11.2 ± 3.7 yr, bone age of 9.3 ± 3.1 yr, height SDS (British 1965 standards) -3.1 ± 1.1. GH mean dose was 48µg/kg.d and GH treatment duration was 5.4 ± 3.0 yr. Estrogen replacement was started late, at CA of 14.3 ± 2.0 yr in GH-treated and at 14.9 ± 1.9 yr in GH-untreated patients, and the rate of spontaneous puberty was similar between the groups (GH-treated 16.8% vs. GH-untreated 22,8%, P=0.304). Adult height was significantly higher after GH treatment (150.1 ± 5.8 cm vs. 143.3 ± 7.2 cm in GH-treated vs. untreated TS patients, respectively, P & lt; 0.001), even with a small but significant difference in target height between the groups (158.2 ± 4.8 vs. 159.8± 4.5 cm in GH-treated vs. untreated TS patients, respectively, P= 0.015). More than half of the TS GH-treated patients reached normal adult height (equal or higher than 150.2 cm), whereas only 15.6% of GH-untreated patients reached it. Conclusion: Despite the delayed diagnosis of TS patients in our cohort, GH treatment was associated with a significant height gain, and the TS GH-treated group was around 7 cm taller than the GH-untreated group.
