Clinical profile of 93 cases of 46, XY disorders of sexual development in a referral center.

The term DSD refers to disorders that affect the normal process of sexual development causing disagreement between chromosomal, gonadal and phenotypic sex, and this study aimed to describe the clinical profile of a group with DSD 46, XY joined on DSD Clinic of Hospital of Salvador, Bahia Clinics. It was a retrospective study of medical records of survey data of 93 patients with DSD 46, XY. Among the patients studied 50.5% had no defined etiology and 20.4% had androgen insensitivity syndrome (AIS), 63.4% had been initially recorded in males, 31 (33.3%) in females, being that in two it was necessary to reassignment. All patients with complete AIS pure gonadal dysgenesis and had female genitalia. Others have been diagnosed with genital ambiguity or severe hypospadias and cryptorchidism. The gonads were palpable at the first consultation in 75.3% of patients. It is important to establish an active surveillance program for these patients. The first assessment took place before the age of ten in more than 50% of cases, which shows that much needs to be done for medical education and community about the DSD. Because the phenotypic variability of sexual development disorders was noted that the clinical profile of patients studied ranged between different etiologies, including hindering the diagnostic conclusion of these individuals.

Is there an association between prostate-specific antigen and androgen levels in 46, XX patients with congenital adrenal hyperplasia?

INTRODUCTION: Congenital adrenal hyperplasia (CAH), a genetic disease characterized by defective cortisol synthesis and excessive levels of sex hormones, can cause precocious puberty in both sexes in untreated individuals and virilization in female patients with a 46, XX karyotype. The female paraurethral (Skene's) gland has been reported as prostate analogous. Growth of prostate tissue is associated with androgen production; therefore, prostate-specific antigen (PSA) levels may represent a marker of virilization in 46, XX patients with CAH. OBJECTIVES: To describe PSA levels in 46, XX patients and evaluate whether higher PSA levels are associated with androgenization and the severity of the disease. STUDY DESIGN: Sixty-six patients with CAH and a 46, XX karyotype were included, irrespective of age. Serum PSA, testosterone, 17-hydroxyprogesterone (17-OHP) and androstenedione levels were measured. Patients' age, age at diagnosis, forms of the disease, Prader classification, bone age assessment, sex of rearing, surgery, and the presence of clinical complications were obtained from their medical records. RESULTS: The mean age of patients was 11.45 ± 10.74 years. Forty-three patients (65%) were diagnosed neonatally at a median of 0.08 years (mean 1.47 ± 2.34 years), with registers of 17-OHP measurements (Guthrie test) being available in 51%. Testosterone, 17-OHP and androstenedione were significantly high. PSA was detectable in 25% of cases (levels >0.01 ng/ml), with a mean of 0.03 ± 0.09 ng/ml, and only in patients over five years of age. A correlation was found between PSA and age (p < 0.001), age at diagnosis (p = 0.002), testosterone (p = 0.001) and androstenedione (p = 0.023). There was no correlation between PSA and the forms of CAH or Prader classification. A sub-analysis of the patients over five years of age in whom PSA was detectable also showed that there was a correlation between PSA (p < 0.05) and age at analysis, age at diagnosis, testosterone and androstenedione levels. DISCUSSION: Limitations of this study include the small sample size due to the rareness of the disease, its retrospective nature, the absence of a control group, the fact that the sample was selected at two referral centers, which could have resulted in a selection bias, and the use of different reference values in the different laboratories conducting the PSA tests. CONCLUSIONS: PSA is detectable in 25% of 46, XX patients with CAH, only after five years of age. PSA level increases significantly with age, age at diagnosis, and testosterone and androstenedione levels, confirming a correlation between PSA levels and elevated androgen levels.

[Elevated levels of leptin and LDL-cholesterol in patients with well controlled congenital adrenal hyperplasia]. / Valores elevados de leptina e LDL-colesterol em pacientes com hiperplasia adrenal congênita bem controlados.

OBJECTIVE: The objective of this study was to evaluate patients with classic CAH before and after treatment with glucocorticoids/mineralocorticoid and compare the metabolic profile of the well controlled (WC) and poorly controlled (PC) group. SUBJECTS AND METHODS: We selected newly diagnosed patients and patients monitored for CAH, classical form, regularly using or not glucocorticoids/mineralocorticoid in the Genetics Service Hupes-UFBA, seen from March/2004 to May/2006. All patients underwent detailed clinical evaluation and laboratory tests (glucose, sodium and potassium; total cholesterol, HDL, LDL, triglycerides and uric acid; leptin, 17-hydroxyprogesterone, total testosterone, C peptide, and insulin). Patients with normal androgens were classified as well controlled (WC), and those with high levels of androgens either using or not glucocorticoids/mineralocorticoids were classified as poorly controlled (PC). RESULTS: We studied 41 patients with CAH: 11 in the WC group and 30 in PC group. Leptin and LDL cholesterol levels were higher in WC than in the PC group (p < 0.05). Uric acid values were lower in WC compared with the PC group (p < 0.05). CONCLUSION: Adequate control of CAH with steroids seems safe, as it is associated with only mild changes in lipid profile and leptin values. No other metabolic abnormality was associated with glucocorticoid use. The reason for lower uric acid levels found in WC CAH patients is unknown and should be further studied.

Valores elevados de leptina e LDL-colesterol em pacientes com hiperplasia adrenal congênita bem controlados / Elevated levels of leptin and LDL-cholesterol in patients with well controlled congenital adrenal hyperplasia

OBJETIVO: O objetivo deste estudo foi avaliar pacientes com HAC clássica antes e após tratamento com glicocorticoides e/ou mineralocorticoides e comparar o perfil metabólico entre o grupo bem controlado (BC) e mal controlado (MC). SUJEITOS E MÉTODOS: Foram selecionados pacientes recém-diagnosticados e pacientes em acompanhamento por HAC, forma clássica, em uso regular ou não de glicocorticoides/mineralocorticoides do Serviço de Genética do Hupes-UFBA, atendidos de março/2004 a maio/2006. Todos os pacientes foram submetidos a avaliação clínica detalhada e exames laboratoriais (glicemia, sódio e potássio, colesterol total, HDL, LDL, triglicerídeos, ácido úrico, leptina, 17-hidroxiprogesterona, testosterona total, peptídeo C e insulina). Os pacientes com valores normais de andrógenos foram classificados como bem controlados (BC) e os com valores elevados de andrógenos em uso ou não de glicocorticoides/mineralocorticoides foram classificados como mal controlados (MC). RESULTADOS: Foram estudados 41 pacientes com HAC: 11 no grupo BC e 30 no grupo MC. Leptina e LDL colesterol estavam mais elevados no grupo BC que no MC (p < 0,05). Valores de ácido úrico eram menores no grupo BC quando comparados com MC (p < 0,05). CONCLUSÃO: O controle adequado da HAC com glicocorticoides parece seguro, pois está associado a alterações discretas no perfil lipídico e da leptina. Não observamos outras alterações metabólicas associadas ao uso de glicocorticoides. O motivo para o menor valor de ácido úrico encontrado nos pacientes com HAC bem controlada não é conhecido e deve ser mais bem estudado.
