RESUMEN

PURPOSE: Almost every female classic galactosemia patient develops primary ovarian insufficiency (POI). The unique pathophysiology of classic galactosemia, with a severely reduced follicle pool at an early age, requires a new therapeutic approach. This study evaluated the effect of dehydroepiandrosterone (DHEA) on ovarian tissue in a galactose-induced POI rat model. METHODS: Pregnant rats were fed with either a normal or a 35% galactose-containing diet from day 3 of conception continuing through weaning of the litters. Galactose-exposed female offspring were further divided into 5 groups on PND21. The first group received no application. Treatment groups were fed orally by gavage once daily with sesame oil (group 2), or DHEA at doses of 0.1 mg/kg (group 3), 1 mg/kg (group 4) or 10 mg/kg (group 5) until PND70. Fertility rates of mothers with galactosemia, body weights (BWs), and ovarian weights of the litters from PND21 to PND70 were recorded. Ovarian follicle count, immunohistochemistry for proliferation and apoptosis marker expressions and TUNEL for cell death assessment were performed in offspring ovaries. RESULTS: Decreased fertility, ovarian/body weights were observed under galactosemic conditions, together with decreased follicle number and increased atresia. Improved postnatal development, primordial follicle recruitment and follicular growth were observed after DHEA treatment. After DHEA treatment, the expression of Ki67 protein was found to be increased; elevated expression of cleaved-caspase-3 under galactosemia was found to be reduced. CONCLUSIONS: Our data suggests that DHEA treatment may be a potentially useful clinical therapy to improve ovarian ageing in women with POI-induced by galactosemia.

RESUMEN

BACKGROUND: For decades androgens have been considered detrimental to follicle maturation. Animal studies now suggest that they are essential for normal folliculogenesis. Especially in women with premature ovarian aging (POA), recent IVF data in humans are supportive. The literature also suggests an association between recently reported ovarian genotypes of the FMR1 gene and ovarian aging patterns. We, therefore, attempted to determine a potential difference in androgen concentrations and androgen interactions in women with POA who do or do not become pregnant while undergoing androgen supplementation, and whether androgen concentrations and pregnancy chances are affected by FMR1 genotypes. METHODS: We longitudinally assessed androgen metabolism in 91 women with POA, following pre-supplementation with micronized dehydroepiandrosterone (DHEA) prior to IVF. IVF outcomes were assessed based on androgen levels and ovarian FMR1 genotypes. RESULTS: The mean age of the women was 39.8 ± 4.4 years; the clinical pregnancy rate was 25.3%. Total androgen concentrations were not associated with pregnancy; however, in women with abnormal FMR1 genotypes, but not those with the normal genotype, free testosterone significantly affected clinical pregnancy potential (ß = 1.101, SE ± 0.508, P = 0.03). At the start of the IVF cycle, interactions of DHEA with total and free testosterone also significantly affected subsequent pregnancy rates (ß = -0.058, SE ± 0.023, P = 0.01 and ß = -0.496, SE ± 0.197, P = 0.012). CONCLUSIONS: Androgen interactions significantly influence IVF pregnancy rates in women with POA, with the impact of total androgens on cycle outcomes varying according to FMR1 genotypes. These observations suggest that the effectiveness of androgen supplementation in women with POA varies based on FMR1 genotypes, and defines androgen deficiency as a subset of diminished ovarian reserve.

RESUMEN

BACKGROUND: Premature ovarian failure is diagnosed with a picture of amenorrhea, elevated follicle-stimulating hormone (FSH), and age under 40 years. Twenty percent (20%) of patients with premature ovarian failure have a concomitant autoimmune disease. Cases of premature ovarian failure associated with Sjögren syndrome have been reported in the literature. PATIENT AND METHOD: We report a case of a 42-year-old white woman with Sjögren syndrome and premature ovarian failure who underwent a reversal of her premature ovarian failure and restoration of normal menses using an elimination diet protocol. The patient was diagnosed with her rheumatological condition in 2005 and started on disease-modifying antirheumatoid drugs, which were taken intermittently due to a concern over medication side-effects. Her menses became irregular at the time of initial diagnosis and finally ceased in 2006, with a dramatic elevation in her FSH, indicative of autoimmune-induced premature ovarian failure. In March 2009, she commenced an elimination diet protocol, eliminating gluten, beef, eggs, dairy products, nightshade vegetables, refined sugars, and citrus fruit for 4 months. RESULTS: Her repeat laboratory tests after 4 months showed a drop in FSH from 88 to 6.5 and a drop in erythrocyte sedimentation rate from 40 to 16. Her menses also resumed and her rheumatological symptoms significantly improved. CONCLUSIONS: It is hypothesized that the restoration of normal menses was caused by reduced inflammation in the ovarian tissue and supports the hypothesis that the gut immune system can influence autoimmune disease and inflammation.
