Abstract

Using an ultrasensitive assay, prostate-specific antigen (PSA) has been detected in female serum and has been proposed as a potential marker of androgen excess in hirsute women. Measurement of PSA levels in serum may play a role in monitoring hirsutism during antiandrogen therapy. We investigated the role of PSA as a marker of androgen activity in hirsute patients taking spironolactone together with oral contraceptive pills containing ethinyl estradiol and gestodene. Twenty-eight hirsute patients were included in the study. Clinical and biochemical variables including serum levels of PSA (using an ultrasensitive chemiluminscent immunoassay), dehydroepiandrosterone sulfate, total testosterone, free testosterone and 17-hydroxyprogesterone concentrations were recorded at baseline and after six cycles of treatment. Fifteen healthy women were included in the study as controls. Serum PSA levels in hirsute women were clearly higher than in the control group (0.023 +/- 0.004 vs. 0.006 +/- 0.003 ng/ml, p < 0.001) and correlated with baseline serum free testosterone concentrations (r = 0.518, p = 0.005). After 6 months, serum PSA concentrations as compared with baseline values did not change significantly in patients who were given spironolactone plus contraceptive pills (p = 0.4) despite a marked decrease in total testosterone, free testosterone, 17-hydroxyprogesterone, dehydroepiandrosterone sulfate and hirsutism score (p < 0.05). Thus, serum PSA levels in hirsute women were higher than in non-hirsute healthy controls. A 6-month course of treatment with spironolactone combined with contraceptive pills containing ethinylestradiol and gestodene did not reduce high serum PSA levels in these subjects. In conclusion, the serum PSA level is not a convenient biochemical marker with the available assays for the management of hirsute women treated with the combination of spironolactone and oral contraceptives.

Linkage between I172N mutation, a marker of 21-hydroxylase deficiency, and a single nucleotide polymorphism in Int6 of CYP21B gene: a genetic study of Sardinian family.

Congenital adrenal hyperplasia (CAH) is a genetic disorder due to 21-hydroxylase deficiency. More than 90% of CAH cases are caused by mutations of CYP21B gene, most of which are the result of microconversion events between the functional gene and its pseudogene. Using a combination of RFLP and direct sequencing analysis, in this paper we describe the genetic study of a Sardinian family carrying I172N mutation in linkage with a SNP namely 1636 Int6. The characterization of new polymorphisms in CYP21B can improve the analysis of segregation of CYP21B mutated alleles especially in genetic familial studies. The analysis of linkage between specific mutations and this SNPs, especially if focused on genetic familial studies, may improve the quality of genetic analysis of 21-hydroxylase deficiency.

Adrenal and gonadal hormone variations during a febrile attack in a woman with tumor necrosis factor receptor-associated periodic syndrome.

CONTEXT: TNF-receptor-associated periodic syndrome (TRAPS) is a hereditary fever syndrome that results from mutations in the TNF-receptor superfamily 1A gene (TNFRSF1A). It is characterized by periodic fever, arthralgia, abdominal pain, myalgia, headache, and skin lesions. OBJECTIVE: Because adrenal and gonadal hormone cascades are modulated by TNF, this study aimed to investigate specific hormones and enzyme steps during an attack phase in a woman with TRAPS. DESIGN: Morning blood samples were taken from a 38-yr-old woman before, during, and after the febrile episode in the late luteal, menstrual, and early follicular phase of the menstrual cycle, respectively. RESULTS: Serum cortisol levels were markedly increased throughout the entire observation period and demonstrated a dip during the attack phase. In contrast, serum levels of dehydroepiandrosterone and 17-hydroxyprogesterone demonstrated a sharp rise during the febrile episode. Dehydroepiandrosterone in relation to androstenedione or cortisol was increased. Indicative of aromatase activation, estrone and 17beta-estradiol demonstrated a marked increase during the attack phase. CONCLUSION: This study suggests that some important steroid hormone-conversion steps are activated (aromatase) and inhibited (second step of the P450c17 and the 3beta-hydroxysteroid dehydrogenase) during the inflammatory attack phase in a TRAPS patient. These changes of enzyme pathways are typical on the basis of increased TNF signaling.

Adrenal insufficiency in meningococcal sepsis: bioavailable cortisol levels and impact of interleukin-6 levels and intubation with etomidate on adrenal function and mortality.

CONTEXT: Adequate adrenal function is pivotal to survive meningococcal sepsis. OBJECTIVES: The objective of the study was to evaluate adrenocortical function in meningococcal disease. DESIGN: This was an observational cohort study. SETTING: The study was conducted at a university-affiliated pediatric intensive care unit. PATIENTS: Sixty children with meningococcal sepsis or septic shock participated in the study. MAIN OUTCOME MEASURES: The differences in adrenal function between nonsurvivors (n = 8), shock survivors (n = 43), and sepsis survivors (n = 9) on pediatric intensive care unit admission were measured. RESULTS: Nonsurvivors had significantly lower median cortisol to ACTH ratio than shock survivors and sepsis survivors. Because cortisol binding globulin and albumin levels did not significantly differ among the groups, bioavailable cortisol levels were also significantly lower in nonsurvivors than sepsis survivors. Nonsurvivors had significantly lower cortisol to 11-deoxycortisol ratios but not lower 11-deoxycortisol to 17-hydroxyprogesterone ratios than survivors. Using multiple regression analysis, decreased cortisol to ACTH ratio was significantly related to higher IL-6 levels and intubation with etomidate (one single bolus), whereas decreased cortisol to 11-deoxycortisol ratio was significantly related only to intubation with etomidate. Aldosterone levels tended to be higher in nonsurvivors than shock survivors, whereas plasma renin activity did not significantly differ. CONCLUSIONS: Our study shows that the most severely ill children with septic shock had signs of adrenal insufficiency. Bioavailable cortisol levels were not more informative on adrenal function than total cortisol levels. Besides disease severity, one single bolus of etomidate during intubation was related to decreased adrenal function and 11beta-hydroxylase activity. Decreased adrenal function was not related to decreased 21-hydroxylase activity. Based on our results, it seems of vital importance to take considerable caution using etomidate and consider combining its administration with glucocorticoids during intubation of children with septic shock.
