Reversal of premature ovarian failure in a patient with Sjögren syndrome using an elimination diet protocol.

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.

Maternal supplementation differentially affects the mother and newborn.

Although studying the effect of supplementation on maternal health or the outcome of pregnancy was not a primary goal of the Institute of Nutrition of Central America and Panama Oriente Longitudinal Study, many important findings in these areas were produced. As part of the study, a food supplementation program was implemented. Two villages received Atole, a gruel containing protein and energy, and 2 matched villages received a refreshing, low-energy drink containing no protein. Both drinks contained micronutrients. Some women did not choose to consume the supplements and those who did consumed widely varying amounts. More volume of Fresco was consumed than Atole. The energy in the supplements improved birthweight, with no apparent additional benefit from protein or micronutrients. Researchers identified several groups of women who benefited from supplementation more than others by having babies with higher birthweights, including those with poorer current nutritional status and those who consumed high amounts of the supplement continuously from one pregnancy to the next. Results from the study provided an early indication that supplementation might increase the duration of gestation and, thus, reduce preterm birth. On the other hand, maternal supplementation did not substantially alter the duration of postpartum amenorrhea once concurrent infant supplementation was taken into account. Finally, findings from this study provided evidence of a biological trade-off between maintenance of maternal nutritional status and increasing fetal size that was responsive to both current maternal nutritional status and supplement intake but not to the mother's nutritional status earlier in life.

Predictors of recovery of ovarian function after weight gain in subjects with amenorrhea related to restrictive eating disorders.

OBJECTIVE: The aim of the present study was to investigate the anthropometric and endocrine characteristics of subjects with amenorrhea related to eating disorders after weight recovery, in order to identify factors connected with the resumption of menses. METHODS: Clinical data, body composition parameters and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, cortisol, leptin and insulin were assessed in two groups of young women classified according to menstrual status after weight rehabilitation: 43 subjects who displayed persistent amenorrhea and 34 who resumed menses. Univariate and multivariate logistic regression analyses were used to examine the relationships between the different parameters and menstrual recovery. RESULTS: The patients who resumed menses had low initial weight and BMI, and a greater difference between current and initial BMI (DeltaBMI), than those with amenorrhea. No differences were observed in lean mass, body fat or bone density between the two groups. Moreover, the reduction in FSH and the increase in LH, insulin and leptin emerged as significant predictors of menstrual recovery. Increased DeltaBMI and insulin continued to be positive predictors in the multivariate analysis. CONCLUSION: Following weight rehabilitation, the individual's metabolic set point before weight loss and the current insulin levels appear significant in predicting the reactivation of reproductive function.

Maintained malnutrition produces a progressive decrease in (OPG)/RANKL ratio and leptin levels in patients with anorexia nervosa.

OBJECTIVE: Osteoprotegerin (OPG) and receptor activator of nuclear factor-kappaB ligand (RANKL) are key factors in bone remodeling in patients with anorexia nervosa (AN) and osteopenia. The purpose of this study was to investigate basal serum levels of OPG, RANKL and leptin, as well as bone mineral density (BMD) measured by DEXA at lumbar vertebrae L1-L4, and their evolution during one year in two groups of patients with AN. MATERIAL AND METHODS: Group I included 10 adolescent girls suffering from malnutrition and secondary amenorrhea with an evolution of more than one year at the beginning of the study who received oral estrogen treatment throughout the follow-up period. Group II comprised 10 girls with malnutrition and secondary amenorrhea with an evolution of less than one year who received nutritional treatment only. All parameters were compared with those of a control group of 19 healthy, age-matched girls with normal BMI and regular menstrual cycles. RESULTS: The OPG/RANKL ratio was significantly decreased (p<0.05) after 1 year in group I, a fact that was due to an increase (p<0.05) in serum RANKL values. A correlation between OPG/RANKL and BMD was found in group I at the beginning of the study (r = 0.95; p<0.001). Patients in this group showed lower BMD values (p<0.01), both at diagnosis and at the end of the study, than those of group II patients, who showed normal BMD values. CONCLUSION: The decrease in the OPG/RANKL ratio in girls with AN could partly explain the increase in bone loss that occurs in these patients.

Development of a medical nutrition therapy protocol for female collegiate athletes.

Nutrition intervention can improve athletic performance and reduce the risk of nutrition related problems in women athletes. The current healthcare environment demands that dietitians document the outcomes of the medical nutrition therapy (MNT) they provide. This requires the development and validation of MNT protocols so that outcomes can be documented and compared in similar populations across multiple settings. The purpose of this project was to develop a sports nutrition management MNT protocol for collegiate women athletes. A registered dietitian currently working with collegiate women athletes collaborated with four dietitians from the community to develop an MNT protocol. Further testing and validation using this MNT protocol will help dietitians document the outcomes of their interventions in this population.

Metformin to restore normal menses in oligo-amenorrheic teenage girls with polycystic ovary syndrome (PCOS).

PURPOSE: To describe our clinical experience in using Metformin combined with a high protein-low carbohydrate diet to restore normal menstrual cycles in teenaged females with polycystic ovary syndrome (PCOS). METHODS: To enter the study, patients had to have well-documented PCOS, be oligo- (six cycles or less in the preceding year) or amenorrheic (absence of menstrual cycles for 1 year), and not have exclusionary diseases or drugs. Accompanying a high protein-low carbohydrate diet, Metformin (1.5-2.55 g/day) was given for 10.5 +/- 6.4 months (range, 4.5-26.5 months). Follow-up every 8-10 weeks for > or =6 months was scheduled with interval history, review of menstrual status, assessment of any Metformin-related side effects, brief physical examination, and determination of weight and blood pressure. RESULTS: All 11 girls had normal fasting blood glucose and glycohemoglobin. Pre-Metformin, five girls were amenorrheic, three had only one menstrual cycle in the previous year, and three had > or =6 cycles/year. With Metformin, 10 of 11 girls (91%) resumed regular normal menses; 39% of 38 follow-up visits with regular normal menstrual cycles were ovulatory with normal luteal-phase serum progesterone (> or =2.3 ng/mL). Of the 11 girls, nine (82%) lost weight; five girls lost > or =11 lb and seven lost > or =5 lb. After adjusting for weight reduction, with Metformin, estradiol and progesterone rose (p =.0014,.027, respectively) (changes consistent with resumption of regular normal menses), total plasma cholesterol fell (p =.026), and there was a downward trend in testosterone (p =.068). CONCLUSION: Metformin safely ameliorates the endocrinopathy of PCOS in previously oligo-amenorrheic teenage females with PCOS, facilitating resumption of normal menses in most girls.

Functional hypothalamic amenorrhoea: a partial and reversible gonadotrophin deficiency of nutritional origin.

OBJECTIVE: Functional hypothalamic amenorrhoea (FHA) is a consequence of low dietary intake as observed in two major pathophysiological conditions, anorexia nervosa and/or intensive physical exercise. The aim of the present study was to assess in women with FHA and normal body mass index (BMI) and apparently normal daily activities, the degree of impairment of GnRH secretion, its nutritional origin and its reversibility. PATIENTS: Twelve women (22-35 years) with FHA not related with exercise and 12 age and BMI matched menstruating controls (NC) were studied. Six women with congenital hypothalamic hypogonadism (CHH), representative of complete gonadotrophin deficiency, were also enrolled for comparison. DESIGN: Plasma oestradiol (E2) and androstenedione (A) levels were measured and the pulsatile profile of LH was studied. A GnRH agonist test, using 100 micrograms S/C of DTrp6 GnRH (Triptorelin) was performed (sampling every 2 h for 24 h). Dietary intake, body composition and nutritional markers (FT3, ferritin, retinol binding protein (RBP), SHBG, IGF-1 and leptin) were measured. All the women with FHA were advised to normalize their diet during four months. The same studies were performed if nutritional markers and body composition were normalized. RESULTS: In FHA, mean plasma E2 and A levels were low. LH pulse frequency and amplitude were significantly reduced compared to NC (P < 0.005). FSH/LH ratio increased rapidly after triptorelin with a significant increase in plasma E2 levels between 18 and 24 h. In contrast, no response to triptorelin was observed in women with CHH. The fat body mass was lower and the lean body mass higher in FHA than in NC. Marked differences in nutritional intake were identified, with altered dietary composition. FHA consumed significantly less fat (P < 0.001) and less carbohydrate (P = NS) than the BMI-matched controls. Mean plasma levels of SHBG were increased whereas mean plasma levels of FT3, ferritin, RBP, IGF-1, and leptin were significantly decreased. Only three patients with FHA kept a balanced diet and improved their body composition after 4 months. LH pulsatile profile and response to triptorelin challenge were normalized in these patients. CONCLUSION: Mild dieting, close to normal but prolonged and characterized by an important fat restriction, is able to interfere with gonadotrophin secretion. Assessment of nutritional markers allows recognition of mild nutritional insufficiency as a common cause of FHAs. The gonadotrophin deficiency is partial and may be reversible after improvement of nutritional intake and body composition.

Energy and nutrient status of amenorrheic athletes participating in a diet and exercise training intervention program.

Chronic energy deficit is one of the strongest factors contributors to exercise-induced menstrual dysfunction. In such cases, macro- and micronutrient intakes may also be low. This study presents the results of a diet and exercise training intervention program. designed to reverse athletic amenorrhea, on improving energy balance and nutritional status in 4 amenorrheic athletes. The 20-week program provided a daily sport nutrition supplement and 1 day of rest/week. The program increased protein intakes for the 3 athletes with a protein deficit to within the recommended levels for active individuals. Micronutrient intakes increased, as did serum concentrations of vitamin B12, folate, zinc, iron, and ferritin. These results indicate that some amenorrheic athletes have poor nutritional status due to restricted EIs and poor food selections. A sport nutrition supplement may improve energy balance and nutritional status in active amenorrheic women.

Treatment of athletic amenorrhea with a diet and training intervention program.

The purpose of this study was to determine the effect of a 15-week diet and exercise intervention program on energy balance, hormonal profiles, body composition, and menstrual function of an amenorrheic endurance athlete. The intervention program reduced training 1 day/week and included the use of a sport nutrition beverage providing 360 kcal/day. Three eumenorrheic athletes served as a comparison group and were monitored over the same 15-week period. The amenorrheic athlete experienced a transition from negative to positive energy balance, increased body fat from 8.2 to 14.4%, increased fasting luteinizing hormone (LH) from 3.9 to 7.3 mIU/ml, and decreased fasting cortisol from 41.2 to 33.2 micrograms/dl. The eumenorrheic subjects showed a 0.4% reduction in body fat, a decrease in follicular phase levels of LH from 7.9 to 6.5 mIU/ml, and no change in cortisol. These results suggest that nonpharmacological treatment can contribute to reestablishing normal hormonal profiles and menstrual cyclicity in amenorrheic athletes.

Effects of maternal nutritional status and maternal energy supplementation on length of postpartum amenorrhea among Guatemalan women.

To investigate the extent to which better maternal nutrition leads to reduction in length of postpartum amenorrhea, multivariate-logistic and linear-regression analyses were applied to data on 339 mother-infant pairs from the longitudinal Guatemalan Four Village Study, 1969-1977. Maternal triceps skinfold thickness was negatively associated with length of amenorrhea when infant supplementation (a proxy for reduced suckling) was accounted for. However, its effect was small: amenorrhea was only 0.5 mo shorter among women at the 75th percentile than among those at the 25th, equivalent to less than even one additional child during the women's reproductive years. Maternal supplementation was not associated with length of amenorrhea when infant supplementation was controlled. This is in contrast to previous studies in which breast-feeding or infant supplementation was not controlled. These results suggest that infant, not maternal, supplementation influences length of postpartum amenorrhea, and that maternal nutritional status has minimal influence.

[Hyperandrogenism in hirsute and obese women. Effects of a low calorie diet]. / Hyperandrogénie de la femme hirsute et obèse. Effets d'un régime hypocalorique.

To investigate the relationship between overweight and hyperandrogenism, a 1500 kcal/day diet was prescribed for 4 months to 23 hirsute and obese patients. This diet decreased body mass index from 29.9 +/- 4.9 to 27.2 +/- 4.4 kg/m2 (P < 0.008), but had no significant effect on fasting insulin levels (18.9 +/- 14.2 vs. 21.1 +/- 9.6 mlU/l). Weight lost increased significantly (P < 0.008) the plasma concentration of sex-hormone binding-globulin (SHBG) from 21.2 +/- 10.6 to 26.2 +/- 13.5 nmol/l and decreased significantly (P < 0.04) the SHBG-unbound testosterone concentration from 9.3 +/- 6.2 to 7.2 +/- 4.8 ng/dl, without changing the concentrations of the main androgens measured in this study. Moreover, during diet 5 patients in amenorrhea and 8 among 13 patients with irregular menstrual cycle recovered regular menses. We concluded that the control of excess body weight in hirsute women is effective but not sufficient to improve hyperandrogenism.

[Hypercarotenemia, amenorrhea and a vegetarian diet]. / Hypercarotinémie, aménorrhée et régime végétarien.

In order to analyse the role of hypercarotenemia in amenorrhoea, we have studied the ovarian function of 20 patients presenting with hypercarotenemia (serum carotene greater than 5 mumol/l). 12 of these were complaining of secondary amenorrhoea (group I), 7 with a normal weight (group I A) and 5 with a weight below 85% of ideal weight (group I B). Another group of 8 patients had normal menstrual cycles and a body weight within normal limits (group II). Group I presented an ovarian insufficiency of hypothalamic origin with an increase in the FSH/LH ratio. The patients in group I A although of normal weight differed from group II by a history of important weight variations, strenuous sports activity and an essentially vegetarian diet, the most likely reason for their hypercarotenemia. The high carotene levels however do not seem to be directly responsible for the amenorrhoea, in view of the normal menstrual cycles of the patients in group II. Hypercarotenemia can be considered as a biologic marker of weight loss with fat mobilisation and low T3 levels. It can also be due to a vegetarian diet. The latter may be an aetiological factor in anovulation by increasing faecal excretion of oestrogens and thus decreasing blood levels of oestradiol particularly when associated with other compounding factors such as excessive physical activity, loss of weight or affective problems.

Amenorrhea associated with carotenemia.

Data are presented for ten women with anovulation, nine of them with amenorrhea, who have associated carotenemia. Classic explanations for carotenemia in amenorrheic patients have been weight loss or anorexia nervosa, yet carotenemia in our patients appeared to be diet induced. All patients consumed a pure or predominantly vegetarian diet; there was no intake of red meats. Clinical and laboratory data of the patients are presented. The amenorrhea of the patient is consistent with hypothalamic hypogonadotropic anovulation (HHA). It appeared that diet modification not only led to reduction in carotene levels, but also improved the menstrual status. The association of carotenemia and menstrual disorders is reviewed. The possibility that carotenemia is related to the development of HHA is discussed.

Dietary amenorrhoea and subclinical hypothyroidism with elevated TSH responsive to weight gain.

A case of dietary amenorrhoea associated with the biochemical picture of subclinical hypothyroidism is described. Both the amenorrhoea and the abnormal thyroid function tests reverted to normal on gaining weight.
