RESUMO

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders requiring lifelong glucocorticoid replacement (GC) therapy. Lack of GC therapy leads to precocious puberty in boys, heterosexual development in girls, accelerated bone maturation and short final height in both sexes. In adolescence, the lack of GC therapy is the cause of menstrual disorders in girls and the development of TART in boys, as a result reducing the reproductive potential in both sexes. On the other hand, an overdose of GC leads to drug-induced Itsenko-Cushing's syndrome. In order to select adequate doses of GC in childhood and adolescence, multiple determinations of 17-hydroxyprogesterone, androstenedione, and testosterone in blood plasma, and thus multiple venous blood sampling are required. The blood sampling requires specially trained medical staff and can effect on the results due to stress reaction especially in young patients. Hence, the development and implementation of a non-invasive method for determining the steroid profile is extremely important in monitoring GC therapy in children. In addition, the currently used immunofluorescence assay cannot determine other adrenal steroids, has a high variation due to the «cross-reaction¼ of steroids that are similar in structure, which inflates the results. Unlike immunofluorescence assay, liquid chromatography and tandem mass spectrometry is more preferable method, since it is more specific and accurate. In this literature review, saliva presented as an alternative substrate and the non-invasive method for determining the steroid profile. This method can solve the above disadvantages, simplify and make more accurate the selection of GC therapy in patients with CAH, which is especially important in childhood.

RESUMO

PURPOSE: Disorders of sex development (DSD) have complex pathogenesis, and evidence suggests an association between MAMLD1 defects and DSD. MAMLD1 is expressed in gonadal tissues and affected males exhibit hypospadias, steroid hormone abnormalities, or gonadal underdevelopment. We performed genetic testing on a newborn patient with severe hypospadias and an elevation of 17-hydroxyprogesterone (17α-OH) for the diagnosis of DSD. METHODS: Genetic testing of the proband and parents was conducted using whole-exome and Sanger sequencing. The identified variant was transfected into HEK293T cells to assess mutant protein expression using western blot (WB) and into steroidogenic NCI-H295R cells to assess MAMLD1 and CYP17A1 transcript levels using qPCR. Molecular dynamics simulations were performed to construct a structural model and analyze potential biological implications. RESULTS: A novel heterozygous variant was identified in the proband's MAMLD1, NM_005491.5: c.1619_1637del (p.Gln540Alafs*72), inherited from the mother. In transfected cells, the wild-type and mutant proteins were 86.2 and 68.3 kDa, respectively, indicating the formation of a truncated protein. While MAMLD1 transcription was not affected, CYP17A1 transcription levels decreased with the variant compared to wild-type, suggesting an impact on the transactivation of CYP17A1. The truncated protein exhibited enhanced hydrophobicity, owing to the absence of the C-terminal structural portion, resulting in a looser protein structure. CONCLUSION: Severe hypospadias in the proband may be attributed to a novel MAMLD1 variant, whereas the 17α-OH elevation might be related to interference with CYP17A1 transcriptional activation. This study expands the spectrum of MAMLD1 variants and underscores the critical role of genetic testing in the diagnosis of DSD.

RESUMO

CONTEXT: Recent guidelines suggest that patients with nonclassic congenital adrenal hyperplasia (NCCAH) stop glucocorticoid therapy after achieving adult height. However, these guidelines do not differentiate between NCCAH genotype groups. OBJECTIVE: Compare ACTH-stimulated cortisol and 17-hydroxyprogesterone (17OHP) levels, and the rate of partial cortisol insufficiency in subjects with NCCAH carrying one mild and one severe (mild/severe) mutation vs subjects with biallelic mild (mild/mild) mutations. METHODS: Retrospective evaluation of the medical records of 122 patients who presented with postnatal virilization and were diagnosed with NCCAH. Patients underwent standard intravenous 0.25 mg/m2 ACTH stimulation testing. Those with stimulated 17OHP level ≥40 nmol/L were screened for the 9 most frequent CYP21A2 gene mutations followed by multiplex ligation-dependent probe amplification. A stimulated cortisol level below 500 nmol/L was defined as partial cortisol deficiency. RESULTS: Patients were subdivided into 3 genotype groups: 77 carried the mild/mild genotype, mainly homozygous for p.V281L mutation; 29 were compound heterozygous for mild/severe mutation, mainly p.V281L/p.I2Splice, and 16 were heterozygous for p.V281L, and were excluded from statistical evaluation. Stimulated cortisol levels were significantly lower in the mild/severe than in the mild/mild group (mean ± SD, 480 ± 90 vs 570 ± 125 nmol/L, P < .001). The mild/severe group exhibited a significantly higher rate of partial cortisol insufficiency (21/28, 75% vs 28/71, 39%, P = .004). Peak 17OHP was significantly higher in the mild/severe group (198 ± 92 vs 118 ± 50 nmol/L, P < .001). CONCLUSION: The high rate of partial adrenal insufficiency in the mild/severe group underscores the need to carefully consider the value of glucocorticoid therapy cessation and the importance of stress coverage in this group.

RESUMO

In this study, we aimed to examine the impact of high endurance training on vascular health parameters and immune-endocrine responses against modified low-density lipoprotein (LDL) particles. This observational, cross-sectional study included high endurance-trained and healthy non-trained subjects. Vascular ultrasound was used to assess vascular health parameters based on carotid intima-media thickness and endothelial function (flow-mediated dilation). Enzyme-linked immunosorbent assays were used to measure interleukin (IL)-8 and IL-10, autoantibody isotypes anti-oxidized LDL (oxLDL) and anti-apolipoprotein B (ApoB-D) peptide. Plasma levels of the corticosterone and 17 α-hydroxyprogesterone hormones were analyzed by mass spectrometry. This study enrolled 96 subjects, of whom 44 were high endurance trained and 52 were healthy non-trained individuals. Smaller carotid intima-media thickness values were observed in the high-endurance trained than in the healthy non-trained males, while no differences were observed between female groups. Flow-mediated dilation measurements did not differ by training or sex. The humoral immune responses to IgG anti-oxLDL and IgM anti-ApoB-D autoantibodies showed an isotype imbalance between the high-endurance trained and the non-trained groups. Immunoendocrine parameters showed inverse correlations between 17 α-hydroxyprogesterone concentrations and carotid intima-media thickness measurements. Direct correlations were found between IL-10 concentrations and flow-mediated dilation measurements. Chronic high-endurance exercise modulates immune-endocrine and vascular health parameters, in a sex-dependent manner.

RESUMO

OBJECTIVES: To study the possible role of serum 17α-hydroxy-progesterone (17αOH-P) levels in predicting favorable responses to follicle-stimulating hormone (FSH) administration in patients with normal serum FSH levels and idiopathic abnormal sperm parameters. DESIGN: Prospective cohort study. SETTING: University-affiliated fertility center. PATIENTS: Fifty patients with oligozoospermia, asthenozoospermia, and/or teratozoospermia and normal serum levels of gonadotropins and total testosterone (TT). INTERVENTION: Treatment with exogenous FSH is administered subcutaneously at a dose of 150 IU 3 times a week for 3 consecutive months. MAIN OUTCOME MEASURE(S): Luteinizing hormone levels, FSH levels, TT levels, 17αOH-P levels, testicular volume, conventional sperm parameters, and seminal spermatid concentration were evaluated before and after therapy. To evaluate the predictive role of pretreatment serum 17αOH-P levels on FSH responsiveness, the doubling of sperm concentration at the end of the FSH administration was considered a positive outcome. RESULTS: After therapy, patients showed a significant increase in sperm concentration, total sperm count (TSC), progressive motility, percentage of normal forms, FSH levels, TT levels, and testicular volume. There was a negative correlation between pretreatment 17αOH-P levels and the posttreatment increase in sperm concentration, TSC, progressive motility, and normal morphology, and a positive correlation with the posttreatment increase in spermatids. Predictive analysis showed that 17αOH-P levels (<1.18 ng/mL) foretold a doubling of sperm concentration with a sensitivity of 90.0% and a specificity of 73.3%, and of TSC with a sensitivity of 91.3% and a specificity of 81.48%. CONCLUSION: The results of this study suggest that pretreatment serum levels of 17αOH-P, a marker of steroidogenic function, appear to be able to predict the success of subcutaneous administration of exogenous FSH in terms of spermatogenesis improvement. Receiver operating characteristic curves indicated that 17αOH-P levels (<1.18 ng/mL) predict a doubling of sperm concentration and TSC after exogenous FSH administration to patients with idiopathic abnormal sperm parameters and normal gonadotropin levels.

RESUMO

AIM: To reveal the peculiarities of steroidogenesis and arterial hypertension in «physiological¼ hyperandrogenism in men. MATERIALS AND METHODS: One-stage simultaneous study. The groups of men with hyperandrogenism caused by increased total testosterone (n=34) and those with hyperandrogenism caused by increased dihydrotestosterone (DHT) (n=66) were compared. In determining the type of hyperandrogenism and allocating patients to groups, DHT and total testosterone levels were determined by enhanced chemiluminescence. Subgroups of men with and without arterial hypertension were compared in the group of patients with hyperandrogenism due to an increase in total testosterone. Body mass index, waist circumference, systolic and diastolic blood pressure, pulse, and LH, SBHG, estradiol, blood multisteroid levels by isotope dilution liquid chromatography/tandem mass spectrometry, glucose, blood lipid spectrum, uric acid, creatinine, renin, potassium, sodium, and blood chloride were assessed in all patients. Patients with arterial hypertension additionally underwent daily BP monitoring, albuminuria assessment, electrocardiography, ocular fundus examination. The baseline threshold level of significance was p<0.05. For multiple comparisons, the p significance level was calculated using the Bonferroni correction. RESULTS: Statistically significant differences were found in the levels of 17-hydroxypregnenolone, 17-hydroxyprogesterone, and androstenedione, which were higher in men with elevated levels of total testosterone. No statistically significant differences in other laboratory parameters were found. No cases of increased blood pressure were detected in the group of men with elevated DHT. In the group of men with elevated total testosterone, 23,5% of men with arterial hypertension without targetorgan lesions were identified, while hyperandrogenism was associated with 17,6% of cases. Arterial hypertension associated with hyperandrogenism was characterized by a rise in blood pressure in the early morning hours. Estradiol levels, while remaining within normal limits, were statistically significantly lower in patients with arterial hypertension compared with men with elevated testosterone but without hypertension. CONCLUSION: No cases of arterial hypertension were observed in «physiological¼ hyperandrogenism due to elevated DHT levels, whereas its incidence in «physiological¼ hyperandrogenism due to elevated total testosterone was 23,5%. The features of steroidogenesis were increased production of 17-hydroxypregnenolone, 17-hydroxyprogesterone, and androstenedione in men with testosterone hyperandrogenism and decreased estradiol production in patients with arterial hypertension compared with patients without testosterone hyperandrogenism.

RESUMO

CONTEXT: Nonclassic congenital adrenal hyperplasia (NCCAH) requires exclusion before diagnosing polycystic ovary syndrome (PCOS). Increasing use of liquid chromatography and tandem mass spectrometry (LC-MS/MS) necessitates revision of immunoassay-based criteria for NCCAH. Measurement of 21-deoxycortisol (21DF) may simplify the diagnosis of heterozygosity (HTZ), the presence of 1 affected CYP21A2 allele, which currently relies on complex molecular studies. OBJECTIVE: We aimed to determine LC-MS/MS-specific criteria for NCCAH and HTZ and compare the diagnostic accuracy of 21DF and 17-hydroxyprogesterone (17OHP). METHODS: A cross-sectional study involving 99 hyperandrogenic females was performed. We identified females who had undergone both a synacthen stimulation test (SST) and CYP21A2 genotyping from 2010 to 2017, and prospectively recruited females referred for an SST to investigate hyperandrogenic symptoms from 2017 to 2021. Steroids were compared between genetically confirmed NCCAH, HTZ, and PCOS. Optimal 17OHP and 21DF thresholds for HTZ and NCCAH were determined by receiver operating characteristic analysis. RESULTS: Basal 17OHP, stimulated 17OHP, and 21DF were measured in 99, 85, and 42 participants, respectively. Optimal thresholds for NCCAH were 3.0 nmol/L and 20.7 nmol/L for basal and stimulated 17OHP, respectively. Basal and stimulated 21DF thresholds of 0.31 nmol/L and 13.3 nmol/L provided 100% sensitivity with specificities of 96.8% and 100% for NCCAH, respectively. Diagnostic thresholds for HTZ of 8.0 nmol/L, 1.0 nmol/L, and 13.6 for stimulated 17OHP, 21DF, and the ratio (21DF + 17OHP)/cortisol each provided 100% sensitivity with specificities of 80.4%, 90.5%, and 85.0%, respectively. CONCLUSION: LC-MS/MS-specific 17OHP thresholds for NCCAH are lower than those based on immunoassay. LC-MS/MS-quantified 17OHP and 21DF accurately discriminate HTZ and NCCAH from PCOS.

RESUMO

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)


Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

RESUMO

PURPOSE: Our primary aim was to compare changes in hematocrit in testosterone-deficient men treated with intranasal testosterone gel vs intramuscular testosterone cypionate. MATERIALS AND METHODS: This 2-arm, open-label, randomized trial recruited men with testosterone deficiency at the University of Miami between August 2020 and October 2022. Men with 2 total testosterone levels <350 ng/dL and hypogonadal symptoms, aged 18-75 years were randomly assigned to receive either intranasal testosterone gel 11 mg 3 times daily or intramuscular testosterone cypionate 200 mg every 2 weeks. The primary outcome was change in hematocrit after 4 months of treatment. Secondary outcomes were changes in serum testosterone, estradiol, prostate-specific antigen, 17-hydroxyprogesterone, and the 6-item International Index of Erectile Function. RESULTS: Of the 81 men randomized, 54 completed treatment (intranasal n=23; intramuscular n=31). The mean age was 47.5 vs 49.5 years, with mean baseline testosterone of 244.6 vs 240.7 ng/dL and mean hematocrit of 44.4% vs 42.7% in intranasal vs intramuscular groups, respectively. Men who received intramuscular injections had a significant increase after 4 months of treatment in mean hematocrit from 42.7% to 46.6% (P < .0001), but there was no significant change in men who received intranasal gel (P = .233). Men in both groups experienced significantly increased serum testosterone levels throughout the study period, though a larger increase was seen in men treated with intramuscular injections (mean change 511 vs 283, P = .025). Men who received injections also experienced an increase in estradiol (mean change 22.9, P < .001), decrease in 17-hydroxyprogesterone (mean change -39.8, P < .0001), and increase in the 6-item International Index of Erectile Function score (mean change 4.8, P = .015); men treated with intranasal gel experienced no such changes. Prostate-specific antigen levels were stable in both groups. CONCLUSIONS: Intranasal testosterone gel does not appear to significantly affect hematocrit levels. Men who wish to avoid polycythemia or changes in estradiol or 17-hydroxyprogesterone levels may benefit from short-acting testosterone therapy formulations such as intranasal gel.

RESUMO

BACKGROUND: We present an intriguing case of primary adrenal lymphoma, with associated primary adrenal insufficiency (PAI), in a patient presenting a transitory partial 21-hydroxylase deficiency during the active phase of the adrenal disease. CASE PRESENTATION: An 85-years old woman was referred because of worsening asthenia, lumbar pain, generalized myalgia and arthralgia. During investigations a computed tomography (CT) scan evidenced two large bilateral adrenal masses, highly suspicious for primary adrenal tumor. The hormonal assessment revealed very low levels of morning plasma cortisol and 24-h urinary cortisol, elevated ACTH levels with low plasma concentration of aldosterone, pointing to the diagnosis of PAI. After diagnosis of PAI our patient started glucocorticoid and mineralcorticoid replacement therapy with clinical benefit. In order to further characterize the adrenal lesions, adrenal biopsy, was performed. The histology revealed a high grade non-Hodgkin lymphoma with an immunophenotype consistent with intermediate aspects between diffuse large B-cell and Burkitt lymphoma, with a high proliferation index (KI-67 > 90%). The patient received chemotherapy with epirubicin, vincristine, cyclophosphamide, and rituximab, associated with methylprednisolone that resulted in a complete clinical and radiological remission within one year. After 2 years from the diagnosis and a total of 6 cycles of rituximab, the patient was in good clinical condition and was taking only the replacement therapy for PAI. The patient initially presented also a slight increase of 17-hydroxyprogesterone (17-OHP) for age that normalize after resolution of lymphoproliferative disease. CONCLUSIONS: In the presence of bilateral adrenal disease and/or in the presence of signs and symptoms of PAI clinicians must exclude the presence of PAL. The evidence of elevated ACTH-stimulated 17-OHP levels also in patients with other adrenal masses, together with the detection of elevated basal 17-OHP levels in our patient make it more plausible, in our view, an effect of the lesion on the "healthy" adrenal tissue residue than a direct secretory activity by the adrenal tumor.

RESUMO

CONTEXT: Crinecerfont, a corticotropin-releasing factor type 1 receptor antagonist, has been shown to reduce elevated adrenal androgens and precursors in adults with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD), a rare autosomal recessive disorder characterized by cortisol deficiency and androgen excess due to elevated adrenocorticotropin. OBJECTIVE: To evaluate the safety, tolerability, and efficacy of crinecerfont in adolescents with 21OHD CAH. METHODS: This was an open-label, phase 2 study (NCT04045145) at 4 centers in the United States. Participants were males and females, 14 to 17 years of age, with classic 21OHD CAH. Crinecerfont was administered orally (50 mg twice daily) for 14 consecutive days with morning and evening meals. The main outcomes were change from baseline to day 14 in circulating concentrations of ACTH, 17-hydroxyprogesterone (17OHP), androstenedione, and testosterone. RESULTS: 8 participants (3 males, 5 females) were enrolled; median age was 15 years and 88% were Caucasian/White. After 14 days of crinecerfont, median percent reductions from baseline to day 14 were as follows: ACTH, -57%; 17OHP, -69%; and androstenedione, -58%. In female participants, 60% (3/5) had ≥50% reduction from baseline in testosterone. CONCLUSION: Adolescents with classic 21OHD CAH had substantial reductions in adrenal androgens and androgen precursors after 14 days of oral crinecerfont administration. These results are consistent with a study of crinecerfont in adults with classic 21OHD CAH.

RESUMO

Weekly intramuscular (250 mg/week) or subcutaneous (275 mg/week) injections of 17-hydroxyprogesterone caproate (17-OHPC) is the only treatment option for the prevention of preterm birth in women with a prior history of preterm delivery.The objective of the current study was to determine the relative distribution of 17-OHPC in selected tissues in adult female SD rats after IM (oily formulation or solution), IV (solution), PO (solution), or intravaginal (suppository) administration.Plasma, uterus, adipose, and liver samples were collected at various times and analysed by LC-MS-MS.The highest concentrations of 17-OHPC were observed in the adipose tissue, after IM (oily formulation), and intravaginal administration.Substantial concentrations of 17-OHPC were also observed in the uterus after IM, intravaginal and IV administration.17-OHPC was not detected in the liver and in any of the tissues tested after PO administration.17-OHPC levels in plasma after intravaginal suppository administration were low despite substantial concentrations in the adipose and the uterus.The distribution of 17-OHPC depends on the formulation, the route of administration, and the sampling time.Low systemic concentrations and substantial distribution in the tissues of interest after intravaginal administration warrants future studies to evaluate the potential of the daily intravaginal route of administration of 17-OHPC.

RESUMO

The study aimed to evaluate the effect of 17 hydroxy progesterone (17-OHPC) on interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in expectantly managed early-onset preeclampsia (PE). A randomized open-label controlled study included women who were diagnosed as early-onset PE if they assigned to expectant management according to the American College of Obstetricians and Gynecologists (ACOG) 2013 criteria for diagnosis of severity of PE. Patients were randomized into Group A (40 patients) received 17-OHPC 250 mg intra-muscular at admission and every 7 days thereafter and Group B (40 patients) was given the usual conservative measures of early-onset PE as a control group. Blood samples were obtained from all participants for measurements of TNF-α and IL-6 levels at admission and repeated at termination of pregnancy. The primary outcome was the mean difference between TNF-α and IL-6 levels before and after treatment in both groups. TNF-α and IL-6 levels at admission were not different between the two groups. However, there was a significant difference concerning these inflammatory biomarkers within the same group at admission and at termination (p < 0.001), with significant decline of IL-6 and TNF-α level in the 17-OHPC treated group and significant rise of IL-6 and TNF-α in the control group. There was a strong positive correlation between systolic blood pressure (SBP) at admission and TNF-α level (r= 0.867, p=0.017), and moderately positive significant correlation between diastolic blood pressure (DBP) at admission and TNF-α (r=0.610, p < 0.001). There was a mild positive significant correlation between IL-6 levels and SBP (r= 0.231, p=0.039), and DBP (r= 0.203, p= 0.041) at admission. In conclusion, 17-OHPC has no effect in improving maternal or neonatal outcomes in conservatively managed early onset PE, although it alters the inflammatory markers levels (IL-6 and TNF-α) that could improve the pathogenesis of PE.

RESUMO

BACKGROUND: The effectiveness of 17-hydroxyprogesterone caproate is unclear as trials have provided conflicting results. With the absence of fundamental pharmacologic studies addressing dosing or the relationship between drug concentration and gestational age at delivery, the effectiveness of the medication cannot be evaluated. OBJECTIVE: This study aimed to evaluate the relationship between plasma concentrations of 17-hydroxyprogesterone caproate and preterm birth rates and gestational age at preterm delivery and to assess the safety of the 500-mg dose. STUDY DESIGN: This study recruited 2 cohorts with previous spontaneous preterm birth; 1 cohort (n=143) was randomly assigned to either 250-mg or 500-mg 17-hydroxyprogesterone caproate, and the other cohort (n=16) was receiving the 250-mg dose for routine care. Steady-state trough plasma concentrations of 17-hydroxyprogesterone caproate obtained at 26 to 30 weeks of gestation were correlated to dose, spontaneous preterm birth rates, and measures of gestational length. Furthermore, maternal and neonatal safety outcomes were evaluated according to dose. RESULTS: There was a dose proportional increase in trough plasma concentrations with the 250-mg (median, 8.6 ng/m; n=66) and 500-mg (median, 16.2 ng/mL; n=55) doses. In 116 compliant participants with blood samples, drug concentration was not related to the spontaneous preterm birth rate (odds ratio, 1.00; 95% confidence interval, 0.93-1.08). However, there was a significant relationship between drug concentration and both the interval from the first administration to delivery (interval A: coefficient, 1.11; 95% confidence interval, 0.00-2.23; P=.05) and the interval from the 26- to 30-week blood draw to delivery (interval B: coefficient, 1.56; 95% confidence interval, 0.25-2.87; P=.02). The spontaneous preterm birth rate or measures of gestational length were not related to dose. Postenrollment cerclage adversely affected all pharmacodynamic assessments because it was a powerful predictor of spontaneous preterm birth (odds ratio, 4.03; 95% confidence interval, 1.24-13.19; P=.021) and both measures of gestational length (interval A [coefficient, -14.9; 95% confidence interval, -26.3 to -3.4; P=.011] and interval B [coefficient, -15.9; 95% confidence interval, -25.8 to -5.9; P=.002]). Initial cervical length was significantly related to the risk of postenrollment cerclage (odds ratio, 0.80; 95% confidence interval, 0.70-0.92; P=.001). Maternal and neonatal safety outcomes were similar in both dosing groups. CONCLUSION: In this pharmacodynamic study, trough plasma 17-hydroxyprogesterone caproate concentrations were significantly associated with gestational age at preterm birth but not with the preterm birth rate. Postenrollment cerclage was a powerful predictor of spontaneous preterm birth rate and gestational length. Initial cervical length predicted the risk of postenrollment cerclage. Adverse events were similar with the 500-mg and 250-mg doses of 17-hydroxyprogesterone caproate.

RESUMO

Biochemical monitoring of treatment in infants with classic congenital adrenal hyperplasia (CAH) is not yet well defined. The aim of this study was to perform a cluster analysis of the urinary steroid metabolome for treatment monitoring of infants with classic salt-wasting CAH. We analyzed spot urine samples obtained from 60 young children ≤ 4 years of age (29 females) with classic CAH due to 21-hydroxylase deficiency treated with hydrocortisone and fludrocortisone by targeted gas chromatography-mass spectrometry (GC-MS). Patients were classified into different groups according to their metabolic patterns (metabotypes) using unsupervised k-means clustering algorithms. Three metabotypes could be discovered. Metabotype #1 (N = 15 (25%)) showed high concentrations of androgen and 17-hydroxyprogesterone (17OHP) precursor steroids, metabotype #2 (N = 28 (47%)) revealed balanced metabolic control, and metabotype #3 (N = 17; 28%) demonstrated severe adrenal suppression with low concentrations of androgen and 17OHP precursor steroids. Daily hydrocortisone doses and urinary concentrations of cortisol and cortisone metabolites did not differ between all three metabotypes. Metabotype #2 had highest daily dose of fludrocortisone (p = 0.006). Receiver operating characteristic curve analysis showed that 11-ketopregnanetriol (area under the curve [AUC] 0.967) and pregnanetriol (AUC 0.936) were most suitable of separating metabotype #1 from #2. For separation between metabotypes #2 vs. #3, the 11-oxygenated androgen metabolite 11-hydroxyandrosterone (AUC 0.983) and the ratio of 11-hydroxyandrosterone to tetrahydrocortisone (AUC 0.970) were most suitable. In conclusion, GC-MS-based urinary steroid metabotyping is a new method to help monitor the treatment of infants with CAH. This method allows classification of under-, over- and adequately treated young children.

RESUMO

BACKGROUND: A rapid and accurate measurement approach for 17α-hydroxyprogesterone (17-OHP) and related steroids in amount/volume-limited clinic samples is of importance for precise newborn diagnosis of congenital adrenal hyperplasia (CAH) and its subtypes in clinic. METHODS: Sixteen steroids (17-OHP, androstenedione, cortisol, tetrahydro-11-deoxycortisol, pregnenolone, progesterone, 11-deoxycorticosterone, corticosterone, 21-deoxycortisol, 11-deoxycortisol, dehydroepiandrosterone, testosterone, aldosterone, 17α-hydroxypregnenolone, dihydrotestosterone and 18-hydroxycorticosterone) were included in the panel of high-throughput microbore ultra-performance liquid chromatography-tandem mass spectrometry. Samples were collected from 126 normal subjects and 65 patients including different subtypes of CAH. RESULTS: The method was validated with satisfactory analytical performance in linearity, repeatability, recovery and limit of detection. Reference intervals for 16 steroids were established by quantifying the level of steroids detected in normal infants. The applicability of the method was tested by differentiating steroid metabolic characteristics between normal infants and infants with CAH, as well as between infants with different CAH subtypes. The relevance of 17-OHP, 21-deoxycortisol, and 17-OHP/11-deoxycortisol for 21-hydroxylase deficiency screening was demonstrated. The level of 11-deoxycorticosterone, 11-deoxycortisol, progesterone and androstenedione can be used for the diagnosis of different rare subtypes of CAH. CONCLUSION: This study provides a strategy for highly efficient steroid analysis of amount/volume-limited clinic samples and holds great potential for clinical diagnosis of CAH.

RESUMO

Steroid cell tumors not otherwise specified are rare sex cord-stromal tumors of the ovary that may produce various steroids and are associated with hirsutism and virilization. We report a rare case of ovarian steroid cell tumor with subsequent spontaneous pregnancy after tumor removal. A 31-year-old woman presented with secondary amenorrhea, hirsutism, and inability to conceive. Clinical and diagnostic evaluations revealed a left adnexal mass and elevated serum total testosterone and 17α-hydroxyprogesterone levels. She underwent a left salpingo-oophorectomy, and histopathological examination confirmed the diagnosis of a steroid cell tumor not otherwise specified. Her serum total testosterone and 17α-hydroxyprogesterone normalized one month after surgery. Her menses resumed spontaneously one month after the operation. She spontaneously conceived 12 months after the surgery. The patient had an uncomplicated pregnancy and delivered a healthy male infant. In addition, we reviewed the literature on steroid cell tumors not otherwise specified with subsequent spontaneous pregnancies after surgery and data regarding pregnancy outcomes.

RESUMO

PURPOSE: Retrospectively analyze the clinical characteristics of patients with nonclassical 21-hydroxylase deficiency (NC21OHD) as well as the relationship between the gene mutations and endocrine hormones. In addition, the relationship between different basal 17-hydroxyprogesterone (17OHP) levels and patients' glucolipid metabolism, hormone levels, pregnancy, and treatment outcomes were examined. METHODS: Clinical data of 78 females with NC21OHD from January 2012 to July 2022 in the Department of Endocrinology and Metabolism of the Third Affiliated Hospital of Guangzhou Medical University were retrospectively analyzed. Diagnosis was based on the 17OHP level combined with clinical manifestations, imaging, and other endocrine hormones and the cytochrome P450 c21, steroid 21-hydroxylase (CYP21A2) gene. RESULTS: The age at diagnosis of the 78 patients was 29.1 ± 4.2 years; 83.3% (65/78) of the patients had menstrual abnormalities, 70 patients were of childbearing age, and 97.1% (68/70) had a history of infertility with a median time of infertility of 3.6 years. Moreover, 71.8% (56/78) of the patients had polycystic ovaries, 26.9% (21/78) had hyperandrogenemia manifestations on physical examination, 66.7% (52/78) had adrenal hyperplasia, 32.1% (25/78) had combined dyslipidemia, and 41.0% (32/78) had combined insulin resistance. Pathogenic mutations were detected in 78.2% (61/78) of the patients with both CYP21A2 alleles; 14.1% (11/78) of the patients had only one allele and 7.7% (6/78) had no pathogenic mutations. The levels of total testosterone (TT), progesterone (P) (0 min, 30 min), and 17-OHP (0 min, 30 min, 60 min) in the adrenocorticotropic hormone (ACTH) stimulation test varied between the groups. Furthermore, patients with NC21OHD were divided into 17OHP < 2 ng/ml, 2 ng/ml < 17OHP < 10 ng/ml, and 17OHP ≥ 10 ng/ml groups according to their different basal 17OHP levels. The 17OHP ≥ 10 ng/ml group had significantly higher TT, FT4, basal and post-stimulation progesterone, and 17OHP, net value added of 17-hydroxyprogesterone (△17OHP), net value added of 17-hydroxyprogesterone/net value added of cortisol ratio (△17OHP/△F), the incidence of adrenal hyperplasia, and number of gene mutations compared to those of the 17OHP < 2 ng/ml group (P < 0.05). NC21OHD infertile patients who received low-dose glucocorticoids showed a significant increase in pregnancy and live birth rates, and a significant decrease in miscarriage rate (all P < 0.05). CONCLUSION: Comprehensive analysis is important as NCCAH diagnoses may be false positive or false negative based on clinical characteristics, hormone levels, and gene detection. Females with NC21OHD showed varying degrees of fertility decline; thus, low doses of glucocorticoid treatment for infertile females with NC21OHD can improve fertility and fertility outcomes.

RESUMO

BACKGROUND: Newborn screening for congenital adrenal hyperplasia (CAH) has benefits with a high adoption rate worldwide. It also has problems of high false positives, which can cause stress to the patient's family with economic losses and unnecessary visits of newborns to hospitals. Therefore, we investigated the influence of birth weight (BW), gestational age (GA), and GA with sampling time on 17-hydroxyprogesterone (17-OHP) concentration and attempted to establish the 17-OHP cutoff values in preterm, low birth weight (LBW), and sick newborns. METHODS: Newborns (n=1,071) born between October 2020 and January 2022 were screened for CAH. Samples from neonates were collected on filter paper with the heel prick method. 17-OHP concentration was measured by time-resolved immunofluorescence with an AutoDELFIA Neonatal 17-hydroxyprogesteron kit and grouped in relation to BW, GA, and GA with sampling time. RESULTS: The median age of newborns at neonatal sample collection was 6 days. 17-OHP concentration showed a statistically significant negative correlation with BW (r=-0.488, p<0.001) and GA (r=-0.560, p<0.001). Full-term and preterm subgroups had a similar decreasing tendency of 17-OHP concentration with increasing sampling time. Application of newly establishing cutoff criteria significantly reduced recall rates to 1.16%, 0.9%, and 1.75% according to each criterion of BW, GA, and GA with sampling time, respectively. CONCLUSIONS: This study presents new 17-OHP cutoff values for preterm, LBW, and sick newborns. These data in our laboratory can be used as a reference by other laboratories for establishing new cutoff criteria to help lower the high recall rate and reduce unnecessary follow-up tests.
