Production of 11-Oxygenated Androgens by Testicular Adrenal Rest Tumors.

CONTEXT: Testicular adrenal rest tumors (TART) are a common complication in males with classic 21-hydroxylase deficiency (21OHD). TART are likely to contribute to the androgen excess in 21OHD patients, but a direct quantification of steroidogenesis from these tumors has not been yet done. OBJECTIVE: We aimed to define the production of 11-oxygenated 19-carbon (11oxC19) steroids by TART. METHODS: Using liquid chromatography-tandem mass spectrometry, steroids were measured in left (n = 7) and right (n = 4) spermatic vein and simultaneously drawn peripheral blood (n = 7) samples from 7 men with 21OHD and TART. For comparison, we also measured the peripheral steroid concentrations in 5 adrenalectomized patients and 12 age- and BMI-matched controls. Additionally, steroids were quantified in TART cell- and adrenal cell-conditioned medium, with and without adrenocorticotropic hormone (ACTH) stimulation. RESULTS: Compared with peripheral blood from 21OHD patients with TART, the spermatic vein samples displayed the highest gradient for 11ß-hydroxytestosterone (11OHT; 96-fold) of the 11oxC19 steroids, followed by 11-ketotestosterone (47-fold) and 11ß-hydroxyandrostenedione (11OHA4; 29-fold), suggesting production of these steroids in TART. TART cells produced higher levels of testosterone and lower levels of A4 and 11OHA4 after ACTH stimulation compared with adrenal cells, indicating ACTH-induced production of testosterone in TART. CONCLUSION: In patients with 21OHD, TART produce 11oxC19 steroids, but in different proportions than the adrenals. The very high ratio of 11OHT in spermatic vs peripheral vein blood suggests the 11-hydroxylation of testosterone by TART, and the in vitro results indicate that this metabolism is ACTH-sensitive.

Gonadal function in adult male patients with congenital adrenal hyperplasia.

CONTEXT: Current knowledge on gonadal function in congenital adrenal hyperplasia (CAH) is mostly limited to single-center/country studies enrolling small patient numbers. Overall data indicate that gonadal function can be compromised in men with CAH. OBJECTIVE: To determine gonadal function in men with CAH within the European 'dsd-LIFE' cohort. DESIGN: Cross-sectional clinical outcome study, including retrospective data from medical records. METHODS: Fourteen academic hospitals included 121 men with CAH aged 16-68 years. Main outcome measures were serum hormone concentrations, semen parameters and imaging data of the testes. RESULTS: At the time of assessment, 14/69 patients had a serum testosterone concentration below the reference range; 7 of those were hypogonadotropic, 6 normogonadotropic and 1 hypergonadotropic. In contrast, among the patients with normal serum testosterone (55/69), 4 were hypogonadotropic, 44 normogonadotropic and 7 hypergonadotropic. The association of decreased testosterone with reduced gonadotropin concentrations (odds ratio (OR) = 12.8 (2.9-57.3)) was weaker than the association between serum androstenedione/testosterone ratio ≥1 and reduced gonadotropin concentrations (OR = 39.3 (2.1-732.4)). Evaluation of sperm quality revealed decreased sperm concentrations (15/39), motility (13/37) and abnormal morphology (4/28). Testicular adrenal rest tumor (TART)s were present in 39/80 patients, with a higher prevalence in patients with the most severe genotype (14/18) and in patients with increased current 17-hydroxyprogesterone 20/35) or androstenedione (12/18) serum concentrations. Forty-three children were fathered by 26/113 patients. CONCLUSIONS: Men with CAH have a high risk of developing hypothalamic-pituitary-gonadal disturbances and spermatogenic abnormalities. Regular assessment of endocrine gonadal function and imaging for TART development are recommended, in addition to measures for fertility protection.

Profiles of 21-Carbon Steroids in 21-hydroxylase Deficiency.

CONTEXT: Marked elevations of 17-hydroxyprogesterone (17OHP) are characteristic of classic 21-hydroxylase deficiency (21OHD). Testing of 17OHP provides the basis for 21OHD diagnosis, although it suffers from several pitfalls. False-positive or false-negative results and poor discrimination of nonclassic 21OHD from carriers limit the utility of serum 17OHP and necessitate dynamic testing after cosyntropin stimulation when values are indeterminate. OBJECTIVE: The objective was to provide a detailed characterization of 21-carbon (C21) steroids in classic 21OHD, which might identify other candidate steroids that could be employed for the diagnosis of 21OHD. SETTING AND PARTICIPANTS: Patients (11 women, 10 men) with classic 21OHD and 21 sex- and age-matched controls seen in a tertiary referral center were studied. METHODS: C21 steroids in the peripheral sera from all subjects, as well as in media from cultured testicular adrenal rest tumor (TART) cells and normal adrenal (NA) cells, were analyzed using liquid chromatography/tandem mass spectrometry (10 steroids). Additionally, the dynamics of C21 steroid metabolism in TART and NA cells were assessed with radiotracer studies. RESULTS: Five C21 steroids were significantly higher in 21OHD patients: 17OHP (67-fold; P < .01), 21-deoxycortisol (21dF; 35-fold; P < .01), 16α-hydroxyprogesterone (16OHP; 28-fold; P < .01), progesterone (2-fold; P < .01), and 11ß-hydroxyprogesterone (11OHP; not detected in controls; P < .01). The same steroids were the highest in media from TART cells relative to the NA cells: 11OHP, 58- to 65-fold; 21dF, 30- to 41-fold; 17OHP, 9-fold; progesterone, 9- to 12-fold; and 16OHP, 7-fold. CONCLUSION: Measurement of 16OHP and 11OHP along with 17OHP and 21dF by liquid chromatography/tandem mass spectrometry might comprise a biomarker panel to accurately diagnose all forms of 21OHD.

[Testicular adrenal rest tumors in adolescents]. / Testikuläre adrenale Resttumoren im Hoden bei Adoleszenten.

BACKGROUND: Testicular adrenal rest tumors (TART) frequently occur in patients with congenital adrenal hyperplasia (CAH) and can be detected and treated in childhood as well as in adolescence. Due to the intricate dilimitation to other testicular masses the correct diagnosis of TART can be problematic. An extensive endocrinologic evaluation and ultrasound examination are mandatory. Even though TART are benign lesions a high-dose therapy with glucocorticoid and/or mineralocorticoid suppletion is necessary for protecion or regain of fertility. METHODS: A surgical approach can be considered, depending on stage of disease and response on drug therapy. Consequent treatment and constant therapy monitoring might significantly improve long-term outcome. RESULTS: Currently there is no validated standard therapy concept, which can be explained by the heterogenity of disease patterns progression and the limited data available, respectively. Therefore treatment should be subject to specialized centres.

Testicular adrenal rest tumors develop independently of long-term disease control: a longitudinal analysis of 50 adult men with congenital adrenal hyperplasia due to classic 21-hydroxylase deficiency.

CONTEXT: Testicular adrenal rest tumors (TARTs) and hypogonadotropic hypogonadism are the two most common causes for male infertility in classic 21-hydroxylase deficiency. Current hypotheses suggest the quality of disease control to be one of the main pathogenic factors for TART development. OBJECTIVE: The aim was to study long-term predictors for TART development in a retrospective longitudinal study. DESIGN: Fifty men with classic 21-hydroxylase deficiency (31 salt wasting, 19 simple virilizing) were investigated. Testicular ultrasound at a median age at investigation of 27 years detected TARTs in 28 of 50 subjects (19 salt wasting, 9 simple virilizing). TART presence was correlated with long-term parameters of disease control during childhood and adolescence obtained from patients' charts: 24-hour urine pregnanetriol, serum 17-hydroxyprogesterone, onset and stage of pubic hair development, testicular growth, and bone age in relation to chronological age. RESULTS: There was no difference in pregnanetriol excretion over lifetime between patients with and without TARTs. Similarly, neither development of pubic hair and testicular volume (Tanner) nor bone age in relation to chronological age differed between the two groups. Furthermore, the two groups had the same body mass index and the same impairment of final height in relation to midparental target height. CONCLUSION: Our longitudinal analysis demonstrates no association between TART presence and parameters of disease control. These data, therefore, argue for other mechanisms more relevant for TART induction including those occurring during fetal development.

Ovarian adrenal rest tumor in a congenital adrenal hyperplasia patient with adrenocorticotropin hypersecretion following adrenalectomy.

OBJECTIVE: Ovarian adrenal rest tumors (OARTs) are rare in contrast to testicular adrenal rest tumors. We report a case of OART in a patient with congenital adrenal hyperplasia who developed Nelson's syndrome after bilateral adrenalectomy. METHODS: We describe the clinical, imaging, and laboratory findings of the patient and review the relevant literature regarding OART and the possible interaction between ACTH and brown adipose tissue. RESULTS: An 18-year-old female with congenital adrenal hyperplasia, who had undergone bilateral adrenalectomy at the age of 10 years, presented with severe hyperpigmentation and hirsutism. Rectal ultrasonography showed a mass in the right ovary. (18)F-fluorodeoxyglucose PET/CT revealed intense uptake both in this mass and in brown adipose tissue located in typical supradiaphragmatic sites. Laparoscopic removal of the ovarian mass confirmed the diagnosis of OART. A systematic review revealed 9 documented cases of OART. As in our case, all presented with elevated ACTH levels. CONCLUSIONS: Common to all documented cases of OART are sustained high ACTH levels that activate the adrenal anlagen tissue in the ovaries.

High prevalence of reduced fecundity in men with congenital adrenal hyperplasia.

CONTEXT: Testicular adrenal rest tumors (TARTs) are regarded to contribute to the high prevalence of subfertility in males with congenital adrenal hyperplasia (CAH). OBJECTIVES: Our objectives were to evaluate reduced fecundity and its possible causes in well-controlled adult males with CAH, and to investigate diagnostic tools for improved treatment monitoring with respect to fertility outcomes. DESIGN: In a cross-sectional study at the Department of Endocrinology at the University Hospital München, Germany, 22 adult male CAH patients (15 salt wasting and seven simple virilizing, age 19-48 yr) were clinically assessed according to their hormonal control. We performed testicular ultrasound (22 of 22), magnetic resonance imaging (18 of 22), and a semen analysis (19 of 22) in the participants. RESULTS: All patients had a pathological semen analysis. TART prevalence was 10 of 22 (eight salt wasting, two simple virilizing). Poor therapy control was present in five patients, and all five had TARTs. Of the other 17 well-controlled patients with normal or suppressed adrenal androgens and 17-hydroxyprogesterone levels, five presented with TARTs. There was a significant correlation between sperm concentration and functional testicular volume (r = 0.70; P = 0.002), TART volume (r = -0.70; P = 0.036), as well as inhibin B levels (r = 0.75; P < 0.0001), respectively. In several men, hormonal control parameters suggested hypogonadism, with glucocorticoid overtreatment as a relevant factor for poor semen quality. CONCLUSIONS: Poor semen parameters are common in male CAH patients. TARTs, most likely reflecting undertreatment, as well as inhibin B are important indicators of fecundity. On the other hand, long-term glucocorticoid overtreatment also seems to contribute to low semen quality.

Asymptomatic testicular adrenal rest tumours in adolescent and adult males with congenital adrenal hyperplasia: basal and follow-up investigation after 2.6 years.

AIM: To study the course of asymptomatic testicular adrenal rest tumours in patients with congenital adrenal hyperplasia (CAH) and the association between tumour changes and glucocorticoid therapy adjustments. PATIENTS AND METHODS: Fifteen male patients with CAH (21-hydroxylase deficiency), in whom asymptomatic testicular adrenal rest tumours had been found at a baseline investigation, underwent scrotal ultrasonography and venous blood sampling (for LH, FSH and testosterone) on average 2.6 years later. The level of hormonal control was assessed by measurement of androstenedione in three diurnal saliva samples. Data on changes in glucocorticoid therapy since baseline were obtained from the patients' records. RESULTS: Tumour decrease, defined as > or =30% decrease in the sum of the longest diameter(s) of the lesion(s), was found in six patients; tumour increase, defined as > or =20% increase, in six and stable tumours in three patients. All three patients with overtreatment showed tumour decrease and of the six patients with undertreatment only one showed tumour decrease. Tumour increase was not only observed in undertreated patients but also in patients with adequate treatment. Changing the night dose of hydrocortisone into dexamethasone, to obtain prolonged ACTH suppression, had resulted in better adrenal suppression in only one patient. CONCLUSIONS: Tumour decrease could be achieved by aiming at adrenal oversuppression, but the required high glucocorticoid doses may induce side effects. In asymptomatic tumours in young male patients with CAH, a practical guideline could be to optimise adrenal suppression to a maximal tolerable glucocorticoid dose and to offer analysis and cryopreservation of semen as soon as the patient can be motivated.

Bilateral testicular adrenal rests after bilateral adrenalectomies in a cushingoid patient with von Hippel-Lindau disease.

We report a case of bilateral testicular masses in a 25-year-old man with von Hippel-Lindau disease presenting with cushingoid symptoms. His medical history was significant for bilateral adrenalectomies secondary to pheochromocytomas, and he began steroid therapy at that time. After exhaustive endocrinologic, radiographic, and physical examinations, the testicular masses were postulated to be active adrenal rest tissue. Bilateral testicular venous sampling found elevated glucocorticoids that were responsive to dexamethasone suppression, which confirmed the testicular masses as testicular adrenal rests without the need for surgical intervention. Successful conservative management consisted of appropriate steroid manipulation and radiographic evaluation and resulted in the resolution of presenting symptoms, a decrease in size of the bilateral testicular masses, and testicular conservation in this young man.

Hyperandrogenism due to 3 beta-hydroxysteroid dehydrogenase deficiency with accessory adrenocortical tissue: a hormonal and metabolic evaluation.

1. Adrenal ectopic tissue has been detected in the paragonadal region of normal women. In patients with congenital adrenal hyperplasia due to 21-hydroxylase (21-OH) deficiency, the manifestation of hyperplasia of paragonadal accessory adrenal tissue has been usually reported to occur in males. Probably, this is the first report of a female with 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) deficiency with ectopic adrenal tissue in ovaries. However, the occurrence of hyperplasia of adrenal rests among women with classical congenital adrenal hyperplasia may not be rare, especially among patients with a late diagnosis. 2. We report a woman with 3 beta-HSD deficiency whose definitive diagnosis was made late at 41 years of age immediately before surgery for the removal of a uterine myoma. During surgery, exploration of the abdominal cavity revealed the presence of bilateral accessory adrenal tissue in the ovaries and in the para-aortic region. The patient had extremely high levels of ACTH (137 pmol/l), DHEA (901.0 nmol/l), DHEA-S (55.9 mumol/l), androstenedione (70.2 nmol/l), testosterone (23.0 nmol/l) and 17 alpha-hydroxypregnenolone (234.4 nmol/l) suggesting 3 beta-HSD deficiency. 3. In view of these elevated androgen levels, with an absolute predominance of DHEA and DHEA-S, we evaluated the effect of this hormonal profile on carbohydrate tolerance and insulin response to glucose ingestion. 4. The patient presented normal glucose tolerance but her insulin response was lower than that of 14 normal women (area under the curve, 3 beta-HSD = 17,680 vs 50,034 pmol/l for the control group over a period of 3 h after glucose ingestion).(ABSTRACT TRUNCATED AT 250 WORDS)

[Virilizing tumor in a woman. Management]. / Tumeur masculinisante chez la femme. Conduite a tenir.

Androgen secreting ovarian or adrenal neoplasms represent a rare cause of hirsutism in women. Because of their small volume and episodic secretion, a number of these tumors may be difficult to diagnose and treat. The authors report a case of lipoid cell tumor of the ovary, which was only detected, because of its small volume, by catheterization of adrenal and ovarian veins. This latter procedure should be performed when strong clinical and biological suspicion is faced by the negativity of other imaging techniques.

Lipoid cell tumor of the ovary.

An androgen-secreting tumor of the left ovary was preoperatively localized in a 55-year-old virilized woman by radioimmunoassay of blood androgens. The blood sample was obtained by bilateral catheterization of the ovarian and adrenal veins using a percutaneous retrograde femoral approach. A total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed, and revealed a lipoid cell tumor of the left ovary and right ovarian stromal hyperplasia. Despite early postoperative return of plasma adrogens to the normal range, virilizing signs persisted almost unchanged 1 year after surgery.
