Complete restoration of fertility in a patient treated for androgen-secreting granulosa cell tumor - Case report.

CASE REPORT: A 35-yr-old patient suffering from secondary amenorrhea for two years before she was diagnosed. Secondary amenorrhea occurred after the first normal vaginal delivery, and it was initially associated with breastfeeding and a formerly diagnosed thyroid disease. Transvaginal ultrasound confirmed a tumorous mass of the right ovary. Blood hormone tests detected high serum inhibin B and Anti-Müllerian hormone levels and high androgen level with no signs of virilization. Surgical treatment was indicated for a definitive diagnosis of suspected sex cord-stromal tumor. Right-sided laparoscopic salpingo-oophorectomy was performed, and the histopathological analysis confirmed the diagnosis of granulosa cell tumor adult type. The oncological team recommended adjuvant chemotherapy after the operation, but the patient did not give an informed consent. One month after surgical treatment, spontaneous menstrual bleeding occurred with normalization of sex hormone levels and the menstrual cycle. Nine months after surgical treatment, the patient was examined again due to secondary amenorrhea. Ultrasound confirmed a vital intrauterine pregnancy. The pregnancy course was normal, and the patient had a full-term spontaneous vaginal delivery of her second child. CONCLUSION: Restoration of fertility after a temporary loss due to hormone-secreting granulosa cell tumor is possible after sparing surgical treatment. The role of adjuvant chemotherapy is controversial, particularly in patients with stage I-II disease because of the rarity of this tumor and the absence of prospective randomized studies.

Mass spectrometry-based glycomic profiling of the total IgG and total proteome N-glycomes isolated from follicular fluid.

Couples with infertility issues have been assisted by in vitro fertilization reproduction technologies with high success rates of 50-80%. However, complications associated with ovarian stimulation remain, such as ovarian hyperstimulation. Oocyte quality is a significant factor impacting the outcome of in vitro fertilization procedures, but other processes are also critical for fertilization success. Increasing evidence points to aberrant inflammation as one of these critical processes reflected in molecular changes, including glycosylation of proteins. Here we report results from a MALDI-TOF-MS-based glycomic profiling of the total IgG and total proteome N-glycomes isolated from the follicular fluid obtained from patients undergoing fertilization through either (1) assisted reproduction by modified natural cycle or (2) controlled ovarian stimulation (GnRH antagonist, GnRH Ant) protocols. Significant inflammatory-related differences between analyzed N-glycomes were observed from samples and correlated with the ovarian stimulation protocol used in patients.

Epidemiology and clinical characteristics of thyroid dysfunction in children and adolescents with type 1 diabetes.

The aim of the study was to evaluate the natural course and potential risk factors of autoimmune thyroiditis (AIT) and thyroid dysfunction, and their influences on growth and glycemic control in children and adolescents with type 1 diabetes mellitus (T1D). The study comprised 148 subjects (age range 1-21 years; males 51%) with T1D. During the interval of 12 years serum levels of thyroid peroxidase (anti-TPO) and thyroglobulin (anti-TG) autoantibodies, thyroid-stimulating hormone (TSH) and tyroksine (T4), were screened annually. Height, weight, body mass index (BMI), glycosylated hemoglobin (HbA1c), insulin dose and the number of severe hypoglycemic episodes, were recorded every 3 months. The mean follow-up was 7 +/- 4.1 years. Prevalence of AIT in subjects with T1D was 15.5%. It was significantly higher in girls (21.9% vs. 9.3%; p = 0.03). The mean age at AIT onset was 11.5 +/- 5.2 years. The mean interval between negative and positive AIT screening was 2.5 +/- 2.3 years. Cumulative incidence of AIT after 6 years of T1D duration was significantly higher in girls (30% vs. 15%; p = 0.03). Prevalence of hypothyroidism was 8.1% with no significant differences in sex distribution. Prevalence of hypothyroidism among subjects with elevated serum thyroid antibodies was 52.2% with significant male preponderance (85.7% vs. 37.5%; p = 0.005). There were no subjects who developed hypothyroidism in absence of thyroid antibodies. Cumulative incidence of hypothyroidism after 3 years from the moment of thyroid antibodies appearance was 55% with significant male preponderance (85% vs. 40%; p = 0.005). The mean interval between T1D onset and hypothyroidism development was 3.3 +/- 2.5 years, and between thyroid antibodies appearance and hypothyreoidism development was 1.7 +/- 1.2 years. The mean age at hypothyroidism onset was 12.7 +/- 5.3 years. There were no differences in growth and metabolic control between patients with and without AIT. The results of the present study confirmed frequent occurrence of AIT and thyroid dysfunction in subjects with T1D. The number of newly diagnosed subjects with AIT reached the peak at the age of puberty. Girls were significantly more predisposed to AIT at any age while amongst subjects with elevated thyroid antibodies boys developed hypothyroidism more frequently. Annual screening of thyroid antibodies in all patients with T1D is recommended, while serum TSH level should be measured in patients with detected thyroid antibodies.
