RESUMEN

There is a strong correlation between the severity of genotypes and 17OH-progesterone levels in patients with the nonclassical form of 21-hydroxylase deficiency (NC-CAH); however, there are few studies regarding the correlation with clinical signs. The aim of the study was to evaluate whether genotypes correlate with the severity of the hyperandrogenic phenotype. A cohort of 114 NC-CAH patients were diagnosed by stimulated-17OHP ≥10 ng/ml. CYP21A2 genotypes were divided into 2 groups according to the severity of enzymatic impairment; mild and severe. Clinical data and hormonal profiles were compared between the 2 groups. Age at onset of manifestations did not differ between children or adults carrying both mild and severe genotypes. Frequencies of precocious pubarche and hirsutism, with or without menstrual abnormalities, were similar between the 2 groups. There were no differences in basal testosterone levels of adult symptomatic females carrying both genotypes, but there were differences between adult females with (92.9±49.5 ng/dl) and without hirsutism (43.8±38 ng/dl) (p=0.0002). Similar frequencies of both genotypes were observed in asymptomatic females and in those with clitoromegaly. Nonclassical genotypes do not predict the severity of phenotype. Asymptomatic and virilized females carrying the same genotype suggest that there is a modulatory effect of genes involved in the androgen pathway on the phenotype.

RESUMEN

BACKGROUND: The presence of virilizing signs associated with high serum androgen levels in postmenopausal women is rare. Virilizing ovarian tumors (VOTs) and ovarian stromal hyperthecosis (OH) are the most common etiologies in virilized postmenopausal women. The differential diagnosis between these two conditions is often difficult. OBJECTIVE: To evaluate the contribution of clinical features, hormonal profiles and radiological studies to the differential diagnosis of VOT and OH. DESIGN: A retrospective study. SETTING: A tertiary center. MAIN OUTCOME MEASURES: Clinical data, hormonal status (T, E2, LH and FSH), pelvic images (transvaginal sonography and MRI) and anatomopathology were reviewed. PATIENTS: Thirty-four postmenopausal women with a diagnosis of VOT (13 women) and OH (21 women) were evaluated retrospectively. RESULTS: Clinical signs of hyperandrogenism were more prevalent in the VOT group than the OH group. Although the VOT group showed higher T and E2 levels and lower gonadotropin levels than the OH group, a great overlap occurred among the hormone levels. A pelvic MRI provided an accurate differentiation of these two conditions. CONCLUSION: In this group of patients, the main features contributing to the differential diagnosis of VOT and OH were serum levels of testosterone and gonadotropins and the presence of an ovarian nodule identified on the MRI. Although the association of clinical, hormonal and radiological features contributes to the differential diagnosis of these two conditions, histopathological analysis remains the gold standard for the diagnosis of ovarian hyperandrogenism in postmenopausal women.

RESUMEN

CONTEXT: Because many women with 21-hydroxylase (21-OH)-deficient nonclassic adrenal hyperplasia (NCAH) carry at least one allele affected by a severe mutation of CYP21, they are at risk for giving birth to infants with classic adrenal hyperplasia (CAH). OBJECTIVE: Our objective was to determine the frequency of CAH and NCAH infants born to mothers with 21-OH-deficient NCAH. DESIGN AND SETTING: We conducted an international multicenter retrospective/prospective study. PATIENTS AND METHODS: The outcome of 203 pregnancies among 101 women with 21-OH-deficient NCAH was reviewed. The diagnosis of 21-OH-deficient NCAH was established by a basal or post-ACTH-stimulation 17-hydroxyprogesterone level of more than 10 ng/ml (30.3 nmol/liter). When possible, genotype analyses were performed to confirm CAH or NCAH in the offspring. RESULTS: Of the 203 pregnancies, 138 (68%) occurred before the mother's diagnosis of NCAH and 65 (32%) after the diagnosis. Spontaneous miscarriages occurred in 35 of 138 pregnancies (25.4%) before the maternal diagnosis of NCAH, and in only four of 65 pregnancies (6.2%) after the diagnosis (P < 0.002). Four (2.5%; 95% confidence interval, 0.7-6.2%) of the 162 live births were diagnosed with CAH. To date, 24 (14.8%; 95% confidence interval, 9.0-20.6%) children, 13 girls and 11 boys, have been diagnosed with NCAH. The distribution of NCAH children and their mothers varied significantly by ethnicity (P < 0.0001, for both). CONCLUSIONS: The risk of a mother with 21-OH-deficient NCAH for giving birth to a child affected with CAH is 2.5%; at least 14.8% of children born to these mothers have NCAH.

RESUMEN

Onze pacientes portadores de deficiência de hormônio de crescimento (DHC) foram tratados por três anos com hormônio de crescimento recombinante autêntico (HCr), em doses de 0,35 a 0,5U/Kg/semana. A velocidade de crescimento pré-tratamento de 2,91 ñ 1,58cm/a elevou-se a 11,07 ñ 2,52cm/a no primeiro ano, 8,62 ñ 2,81cm/a no segundo e 7,63 ñ 1,84 no terceiro ano de terapêutica. Embora tenha ocorrido importante ganho na idade estatural (deltaIE = 4,9 ñ 1 anos), houve também aceleraçäo significante da idade óssea (deltaIO = 4,3 ñ 1,4 anos), com relaçäo deltaIE/deltaIO de 1,1 ñ 0,2. Como o ganho em altura foi acompanhado de proporcional avanço de IO, a possibilidade de obter altura final normal näo seria alcançada a näo ser que a terapêutica com HCr seja instituída mais precocemente, antes do déficit estatural ser demasiadamente severo, como foi na maioria dos pacientes
