Daily fluctuation of cortisol in the saliva and serum of healthy persons.

UNLABELLED: The objective of this study was to evaluate cortisol in the saliva and serum of healthy persons and its daily fluctuations by using immunochemical method on a autoanalyzer. Biological samples: Serum from 14 healthy persons and saliva from 18 healthy persons were taken two times at 8 a.m. and at 4 p.m. Immunochemical assay: The principle of this method is the competitive binding of cortisol present in the analyzed sample and cortisol marked with peroxides on binding parts with specific antibodies. STATISTICAL ANALYSIS: Student t-test. Cortisol in saliva in the morning: 21,2 +/- 16,2 nmol/l and in the afternoon 12,7 +/- 8,1 nmol/l. Cortisol in serum in the morning: 459, 6 +/- 235,2 nmol/l , and in the afternoon 340,5 +/- 207,5 nmol/l. The concentrations of cortisol in saliva are lower than in serum. Cortisol in the serum in the morning is about twenty times higher than cortisol in the saliva at the same time. Cortisol in the serum at afternoon is about twenty-seven times higher than cortisol in the saliva. Individual variabilities of cortisol in the saliva and serum were found during the day.

Clinical outcome and hormone profiles before and after laparoscopic electroincision of the ovaries in women with polycystic ovary syndrome.

The aim of study was to evaluate clinical outcome and hormone profiles of laparoscopic electroincision of the ovaries in women with polycystic ovary syndrome (PCOS) before and after treatment. Forty five clomiphene-citrate resistant women with polycystic ovary syndrome underwent laparoscopic electroincision of the ovaries. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), androstenedione, 17 OH progesterone and beta endorphins were recorded before and 24 hours after the treatment. Clinical and reproductive outcome and hormone profiles were analyzed. Patients were observed during 12 months period. Laparoscopic electroincision of the ovaries was successfully performed without complications in all patients. LH/FSH ratio was 1,66 24 hours after treatment. Serum levels of T, androstenedione, 17 OH progesterone, and beta endorphins were significantly reduced 24 hours after laparoscopic electroincision of the ovaries. In follow-up period 87% of patients were recorded to have regular menstrual cycles and 61% pregnancy rate was achieved spontaneously. Laparoscopic electroincision of the ovaries is an effective treatment in clomiphene-citrate resistant women with polycystic ovary syndrome. The high pregnancy rate of the procedure offers a promising management for patients with polycystic ovary syndrome.

[Effect of erythropoietin on gonadotropic hormones and sexual function in patients on hemodialysis]. / Uticaj eritropoetina na gonadotropne hormone i seksualnu funkciju u pacijenata na hemodijalizi.

INTRODUCTION: Correction of anemia in haemodialysed patients by recombinant human erythropoetin (R-Hu Epo) has been reported to improve sexual functions and hormonal disturbances. The purpose of this study was to evaluate how levels of sexual hormones and sexual function differ before and during a 12 month R-Hu Epo therapy. MATERIALS AND METHODS: Thirty six male patients, mean age 47.5 +/- 12.78 and thirty six female patients, mean age 53.0 +/- 10.14, were included in this study. All patients were dialyzed 3 times per week with haemodialysis mean duration of 4.56 +/- 3.84 years. In order to evaluate sexual activities, the questionnaire was presented to all patients. The levels of prolactin, testosterone, FSH, LH were measured at the beginning of the study and every forth month during the study. RESULTS: During twelve month therapy with Epo, serum hemoglobin significantly increased from 96.0 +/- 13.3 g/dl to 104.0 +/- 17.2 g/dl (p < 0.005), and hematocrit value rose from 0.284 +/- 0.046% to 0.308 +/- 0.052% (p < 0.05). Prolactin was not significantly decreased: at the beginning of the study was 540.3 +/- 302.2 and at the end 537.4 +/- 297.1 microIU/ml. Testosterone concentrations were in normal range in male patients (18.26 +/- 8.61 microIU/ml). There was significant difference in value of LH in female patients which increased from 57.68 +/- 62.58 to 73.79 +/- 68.52 IU/L. Improvement of sexual function was remarkable in female patients. In male patients sexual desire, frequency of sexual intercourse was strengthen after R-Hu epo therapy. CONCLUSION: Better sexual functions in our patients after treatment with R-Hu Epo did not correlate with hormonal disturbances except changes of LH that increased at the end of the therapy.
