RESUMO

Treatments that aid inflammation resolution, immune tolerance, and epithelial repair may improve outcomes beyond high-dose corticosteroids and other broad immunosuppressants for life-threatening acute graft-versus-host disease (aGVHD). We studied the addition of urinary-derived human chorionic gonadotropin/epidermal growth factor (uhCG/EGF; Pregnyl; Organon, Jersey City, NJ) to standard aGVHD therapy in a prospective Phase II clinical trial (ClinicalTrials.gov identifier NCT02525029). Twenty-two patients with Minnesota (MN) high-risk aGVHD received methylprednisolone 48 mg/m2/day plus 2000 units/m2 of uhCG/EGF s.c. every other day for 1 week. Patients requiring second-line aGVHD therapy received uhCG/EGF 2000 to 5000 units/m2 s.c. every other day for 2 weeks plus standard of care immunosuppression (physician's choice). Responding patients were eligible to receive maintenance doses twice weekly for 5 weeks. Immune cell subsets in peripheral blood were evaluated by mass cytometry and correlated with plasma amphiregulin (AREG) level and response to therapy. Most patients had stage 3-4 lower gastrointestinal tract GVHD (52%) and overall grade III-IV aGVHD (75%) at time of enrollment. The overall proportion of patients with a response at day 28 (primary endpoint) was 68% (57% with complete response, 11% with partial response). Nonresponders had higher baseline counts of KLRG1+ CD8 cells and T cell subsets expressing TIM-3. Plasma AREG levels remained persistently elevated in nonresponders and correlated with AREG expression on peripheral blood T cells and plasmablasts. The addition of uhCG/EGF to standard therapy is a feasible supportive care measure for patients with life-threatening aGVHD. As a commercially available, safe, and inexpensive drug, uhCG/EGF added to standard therapy may reduce morbidity and mortality from severe aGVHD and merits further study.

RESUMO

OBJECTIVES: To evaluate the effect of acupuncture at follicular phase of menstrual cycle on anti-mullerian hormone levels in patients with polycystic ovary syndrome undergoing in-vitro fertilisation and to see its impact on assisted reproduction outcome. METHODS: The prospective, randomised, controlled trial was conducted from March 2011 to July 2012 at the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. In the center, the patients randomly chose odd or pair number, the patients with odd numbers classified as an interventional group and the patients with paired numbers as non-interventional group. Infertile polycystic ovary syndrome patients aged 20-40 years were enrolled from the hospital's Assisted Reproduction Centre from March 2011 to July 2012. The patients were randomised into two groups, with one receiving follicular phase acupuncture for 30-40 minutes according to the principles of traditional Chinese medicine, and the other group not getting subjected to acupuncture. Serum and follicular anti-mullerian hormone concentration were determined. RESULTS: Of the 102 patients, 33(32.4%) were in the intervention group, while 69(67.6%) were in the control group. There was no significant effect of acupuncture on serum and follicular fluid anti-mullerian hormone levels in the intervention group compared to the control group (p>0.05). Serum progesterone and estradiol levels on the day of giving human chorionic gonadotrophin, as well as serum progesterone and estradiol levels on the day of oocytes pick-up were significantly lower in the intervention group (p<0.05). Number of embryos transferred, clinical and ongoing pregnancy rates were significantly higher in the intervention group (p<0.05) with a significant decrease of ovarian hyper-stimulation syndrome rate in the intervention group (p<0.05). CONCLUSIONS: Follicular phase acupuncture was found to have a positive effect for polycystic ovary syndrome patients undergoing in-vitro fertilisation, but it had no effect on anti mullerian hormone concentrations.

RESUMO

Controlled ovarian hyperstimulation (COH) impairs the synchronized development of endometrium and embryo, resulting in the failure of embryo implantation. Here, we investigated what effects electroacupuncture had on embryo implantation in COH rats. Female rats were randomly assigned to four groups: normal (N), model (M), electroacupuncture (EA), and electroacupuncture pretreatment (PEA). Rats in groups M, EA, PEA were injected with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin to establish the COH model. Rats in group EA received electroacupuncture treatment from the PMSG injection day to the 3rd day of pregnancy (D3), while those in group PEA received electroacupuncture treatment for 3 days before the PMSG day and continuing to D3. Furthermore, another 30 female rats who received the same treatment as the rats in group PEA were injected with siVEGFR2 into uterine lumen. The endometrial microvascular density (MVD) and the expression levels of vascular endothelial growth factor-A, angiopoietin-1, and fibroblast growth factor-2 were significantly lower in groups M than in groups N and PEA. The percentage of dolichos biflorus agglutinin positive uterine natural killer cells in groups N, EA and PEA was higher than that in group M. After the siVEGFR2 injection, the protein expression levels of vascular endothelial growth factor receptor 2 (VEGFR2), PI3K, p-AKT and p-ERK, the embryo number and the MVD were significantly reduced. In conclusion, electroacupuncture can facilitate embryo implantation in COH rats by activating the VEGFR2/PI3K/AKT and VEGFR2/ERK signaling pathways which have a positive relationship with endometrial angiogenesis.

RESUMO

Painful bladder syndrome/interstitial cystitis is a debilitating chronic bladder disease that primarily affects women. The disease is due to a damage of urothelial cell lining. As a result, potassium particles and other toxic substances in urine can leak into bladder mucosa, causing the symptoms of lower abdominal/pelvic discomfort, pain, increased urination frequency, urgency, nocturia, and so on, all of which can substantially reduce the quality of daily life. There are multiple symptom reliving therapies. Among them, only pentosan polysulfate sodium, sold under the brand name of Elmiron, has been approved for oral use by US Food and Drug Administration. It provides the relief after several months of use. Based on the scientific leads presented in this article, we propose that human chorionic gonadotropin has a therapeutic potential that is worth investigating for the treatment of this disease.

RESUMO

Our previous studies have shown that treatment of pregnant rats with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD; 1 µg/kg) at gestational day (GD) 15 reduces the pituitary synthesis of luteinizing hormone (LH) during the late fetal and early postnatal period, leading to the imprinting of defects in sexual behaviors at adulthood. However, it remains unclear how the attenuation of pituitary LH is linked to sexual immaturity. To address this issue, we performed a DNA microarray analysis to identify the gene(s) responsible for dioxin-induced sexual immaturity on the pituitary and hypothalamus of male pups, born of TCDD-treated dams, at the age of postnatal day (PND) 70. Among the reduced genes, we focused on gonadotropin-releasing hormone (GnRH) in the hypothalamus because of published evidence that it has a role in sexual behaviors. An attenuation by TCDD of GnRH expression emerged at PND4, and no subsequent return to the control level was seen. A change in neither DNA methylation nor histone acetylation accounted for the reduced expression of GnRH. Intracerebroventricular infusion of GnRH to the TCDD-exposed pups after reaching maturity restored the impairment of sexual behaviors. Supplying equine chorionic gonadotropin, an LH-mimicking hormone, to the TCDD-exposed fetuses at GD15 resulted in a recovery from the reduced expression of GnRH, as well as from the defects in sexual behavior. These results strongly suggest that maternal exposure to TCDD fixes the status of the lowered expression of GnRH in the offspring by reducing the LH-assisted steroidogenesis at the perinatal stage, and this mechanism imprints defects in sexual behaviors at adulthood.

RESUMO

CONTEXT: The role of human chorionic gonadotropin (hCG) supplementation on the intrafollicular steroid milieu has been studied. OBJECTIVE: The objective of the study was to assess the impact on steroid levels in follicular fluids (FFs) after different doses of hCG supplementation to recombinant FSH for controlled ovarian stimulation. SETTING: This was a prospective randomized dose-response study conducted at Copenhagen University Hospital, Rigshospitalet, Denmark. PATIENTS: From 62 in vitro fertilization patients, 334 FFs were selected for analyses. INTERVENTIONS: Patients were treated using a GnRH agonist protocol with recombinant FSH 150 IU/d and randomized from stimulation day 1 to supplementation with hCG: D0, 0 IU/d; D50, 50 IU/d; D100, 100 IU/d; and D150, 150 IU/d. MAIN OUTCOME MEASURE: Intrafollicular hormone concentrations in relation to treatment groups, follicular sizes, and embryo quality were measured. RESULTS: In large follicles, hCG supplementation induced a nearly 3-fold increase of estradiol (nanomoles per liter) [D0: 1496; D50: 3138; D100: 4338; D150: 4009 (P < .001)], a significant 3-fold increase of androstenedione, and a 5-fold increase of T (nanomoles per liter) [D0: 15; D50: 38; D100: 72; D150: 56 (P < .001)]. The estradiol to T ratio decreased significantly, with the lowest ratio in D100 and the highest in D0. Large follicles giving rise to good-quality embryos had significantly higher estradiol and progesterone levels and estradiol to T, estradiol to androstenedione, and progesterone to estradiol ratios, compared with small follicles, leading to poor-quality embryos. CONCLUSIONS: Increasing doses of hCG supplementation markedly stimulated the intrafollicular concentration of both estradiol and androgens, with a shift toward a more androgenic milieu. In large follicles with oocytes giving rise to good-quality embryos, the FFs were significantly more estrogenic than in small follicles with oocytes developing into poor quality embryos.

RESUMO

BACKGROUND: Traditional Chinese medicine has been widely used for the treatment of recurrent miscarriage in China and other Asian countries for long time. We conducted this review to systematically summarize the evidences of Chinese herbal medicine (CHM) for the prevention and treatment of recurrent miscarriage in randomized trials, and evaluate the effectiveness and safety of CHM compared with placebo or conventional medicine. METHODS: We searched studies in PubMed, ClinicalTrials, the Cochrane Library, CNKI, SinoMed and VIP databases until December, 2012. Randomized trials on CHM alone or in combination with conventional medicine for recurrent miscarriage compared with placebo or conventional medicine were included. We evaluated the methodological quality of each included trials using the Cochrane risk of bias tool. RESULTS: A total of 41 RCTs (3660 participants) were included. The majority of trials had a high or unclear risk of bias. CHM used alone or plus progesterone-based treatment showed superior effect over progesterone-based treatment in improving live birth rate and embryonic developmental state (measured by B ultrasound). However, there is substantial heterogeneity within each subgroup analysis (I2 ranging from 35% to 71%). CHM plus progesterone and hCG-based treatment was superior to progesterone and hCG-based treatment in improving the embryonic developmental state, but not live birth rate. No severe adverse events were reported in relation to CHM. CONCLUSIONS: Some Chinese herbal medicines or in combination with progesterone-based treatment demonstrated potentially beneficial effect in improving live birth rate and embryonic developmental state for women with recurrent miscarriage. However, due to the substantial heterogeneity among the herbal interventions and limitations of methodological quality of the included trials, it is not possible to recommend any specific CHMs for recurrent miscarriage. Further rigorous clinical trials are warranted to evaluate the efficacy and safety of CHM.

RESUMO

Infertility is generally defined as a couple's inability to conceive after 1 year of unprotected intercourse. When infertile couples seek assistance, a male factor will be identified half of the time. Once the male has been evaluated, there are four main categories to describe his infertility: (1) idiopathic, (2) post-testicular/obstructive, (3) primary-where the Sertoli and/or Leydig cells of the testis fail, and (4) secondary-where there is a problem with the hypothalamus and/or pituitary. The last, hypogonadotropic hypogonadism (HH), accounts for up to 2% of infertile men. HH is either congenital or acquired and usually can be successfully treated by medical intervention. This review will focus on the hypothalamus-pituitary-gonadal axis, specific defects of this coordination center, and potential interventions for improving male-factor fertility.

RESUMO

OBJECTIVE: To analyse the endocrine response in relation to the Δ-4 and Δ-5 pathways of ovarian steroidogenesis after different doses of human chorionic gonadotrophin (hCG) supplementation to recombinant FSH from Day 1 of controlled ovarian stimulation for IVF. DESIGN: A randomized dose-response pilot study. PATIENTS: A total of 62 IVF patients aged 25-37 years with regular cycles and FSH <12 IU/l were treated with a fixed dose of rFSH 150 IU/day and randomized to four hCG dose groups: Dose 0: 0 IU/day, Dose 50: 50 IU/day, Dose 100: 100 IU/day and Dose 150: 150 IU/day. RESULTS: A significant hCG dose-dependent incremental increase was found for progesterone (49-160%), 17-OH-progesterone (223-614%), androstenedione (91-340%) and testosterone (95-338%) from Dose 0 to Dose 150, respectively. Dehydroepiandrosterone (DHEA) showed minor changes during stimulation and no differences between the groups. The highest oestradiol concentrations were observed in Dose 100 and Dose 150. Sex hormone-binding globulin (SHBG) increased similarly in all groups at the end of stimulation. No difference was observed for anti-müllerian hormone (AMH) concentration between the groups, but a 50% decline from the start to the end of the stimulation was found. CONCLUSION: Supplementation with hCG resulted in a clear dose-related response for androgens, progesterone and 17-OH-progesterone. Oestradiol concentration reached maximum levels with an hCG dose of 100 IU/day, suggesting saturation of aromatase function. No difference between the groups was observed for DHEA, supporting that the stimulatory effects of hCG doses on androgens and oestrogen production were mainly induced via the Δ-5 pathway. SHBG, being a biomarker of oestrogen/androgen balance, was not changed by increasing hCG.

RESUMO

STUDY QUESTION: Is it possible to define an optimal dose of hCG in combination with rFSH from the first day of stimulation in the GnRH agonist protocol applied to IVF? SUMMARY ANSWER: Supplementation with hCG from the first day of stimulation may increase the number of top-quality embryos per patient. Daily doses of hCG up to 150 IU are compatible with good live birth rates. A ceiling level of estradiol (E(2)) was reached with hCG doses above 100 IU/day. A positive dose-response was seen for pre-ovulatory progesterone, but concentrations remained below values for which an impairment of endometrial receptivity has been previously reported. We suggest a large clinical trial to be proceeded with a group given 100 IU hCG daily versus a control group. WHAT IS KNOWN AND WHAT THIS PAPER ADDS: Prospective multicentre studies have indicated increased live birth rates and increased number of top-quality embryos when low doses of hCG were associated with FSH. We analysed the clinical, embryological and endocrine aspects of adding increasing doses of hCG to rFSH from the first day of stimulation for IVF. DESIGN: A prospective randomized, controlled, open-label dose-response pilot study was conducted between February 2009 and June 2010 at Copenhagen University Hospital, Rigshospitalet, Denmark. Adequate allocation concealment was assured from sequentially numbered, opaque, sealed envelopes prepared from a computer-generated list. Scoring of the embryos was done in an assessor-blinded way. PARTICIPANTS AND SETTING: Endocrinologically normal IVF patients aged 25-37 years, BMI 18-30 kg/m(2), regular cycles and FSH <12 IU/l, were treated with a fixed dose of rFSH 150 IU/day and randomized to daily hCG dose of 0, 50, 100 or 150 IU from Day 1 of stimulation. Primary end-point was the total number of top-quality embryos on Day 3. DATA ANALYSIS METHOD: Data were analysed by analysis of variance, Kruskal-Wallis test, chi-squared test or Poisson distribution count. MAIN FINDINGS: A total of 62 patients were randomized into four hCG dose groups: Dose 0 (D0; n= 16), Dose 50 (D50; n= 15), Dose 100 (D100; n= 16) and Dose 150 (D150; n= 15). Two patients in D150 were withdrawn after randomization because of major (10- to 30-fold) hCG dosing errors, leaving 13 patients in this group. Thus, the results are based on the per protocol population. The mean numbers of top-quality embryos per patient were D0: 0.8 ± 1.2, D50: 0.5 ± 0.7, D100: 1.2 ± 1.7 and D150: 1.5 ± 1.7 (P= 0.04). All pregnancies were singleton gestations, and the live birth rates per started cycle were D0: 25%, D50: 27%, D100: 25% and D150: 31% (P= 0.98). Steady state level of serum (s)-hCG was reached on Day 6 of stimulation. S-hCG levels (IU/l) on the day of hCG administration were D0: <0.1, D50: 3.1 (2.6-3.6), D100: 5.5 (4.1-7.4) and D150: 11.0 (8.9-13.6) (P< 0.01). The patients receiving hCG supplementation were stratified by 33 and 66% percentiles into three groups according to the concentration of s-hCG on Day 6 of stimulation: 0.5-3.5 IU/l (n= 16), 3.5-8.0 IU/l (n= 14) and 8.0-21.1 IU/l (n= 14). The mean numbers of top-quality embryos in the three groups were 0.5 ± 0.9, 1.1 ± 1.8 and 1.5 ± 1.5, respectively (P= 0.03). The progesterone increments from stimulation Day 1 to the day of hCG triggering were D0 = 49%, D50 = 79%, D100 = 110% and D150 = 160% (P= 0.02). S-androstenedione level was highest in D150 (P< 0.01). S-E(2) was 2-fold higher in the D100 and D 150 compared with D0 (P= 0.09). BIAS, LIMITATION, GENERALISABILITY: Our study has a limited sample size. Supplementation with daily hCG dose up to 150 IU throughout stimulation has never been used before. Hence, this had to be tested in a small study before conducting a larger trial. STUDY FUNDING/COMPETING INTERESTS: Ferring Pharmaceuticals, Research and Development, provided funds for the endocrine measurements. CLINICALTRIAL.GOV REGISTRATION: NCT00844311.

RESUMO

Being overweight or obese is associated with an increased risk for the development of non-insulin-dependent diabetes mellitus, hypertension, and cardiovascular disease. Dyslipidemia of obesity is characterized by elevated fasting triglycerides and decreased high-density lipoprotein-cholesterol concentrations. Endothelial damage and dysfunction is considered to be a major underlying mechanism for the elevated cardiovascular risk associated with increased adiposity. Alterations in endothelial cells and stem/endothelial progenitor cell function associated with overweight and obesity predispose to atherosclerosis and thrombosis. In our study, we analyzed the effect of a low calorie diet in combination with oral supplementation by vitamins, minerals, probiotics and human chorionic gonadotropin (hCG, 125-180 IUs) on the body composition, lipid profile and CD34-positive cells in circulation. During this dieting program, the following parameters were assessed weekly for all participants: fat free mass, body fat, BMI, extracellular/intracellular water, total body water and basal metabolic rate. For part of participants blood chemistry parameters and circulating CD34-positive cells were determined before and after dieting. The data indicated that the treatments not only reduced body fat mass and total mass but also improved the lipid profile. The changes in body composition correlated with the level of lipoproteins responsible for the increased cardiovascular risk factors. These changes in body composition and lipid profile parameters coincided with the improvement of circulatory progenitor cell numbers. As the result of our study, we concluded that the improvement of body composition affects the number of stem/progenitor cells in circulation.

RESUMO

BACKGROUND: The aim of this study was to evaluate the effect of dehydroepiandrosterone (DHEA) supplementation on in vitro fertilization (IVF) data and outcomes among poor-responder patients. METHODS: A randomized, prospective, controlled study was conducted. All patients received the long-protocol IVF. Those in the study group received 75 mg of DHEA once a day before starting the next IVF cycle and during treatment. RESULTS: Thirty-three women with significantly diminished ovarian reserves were enrolled, 17 in the DHEA group and 16 in the control group. The 33 patients underwent 51 IVF cycles. The DHEA group demonstrated a non-significant improvement in estradiol levels on day of hCG (P = 0.09) and improved embryo quality during treatment (P = 0.04) between first and second cycles. Patients in the DHEA group also had a significantly higher live birth rate compared with controls (23.1% versus 4.0%; P = 0.05), respectively. Six of seven deliveries were among patients with secondary infertility (P = 0.006). CONCLUSION: Dehydroepiandrosterone supplementation can have a beneficial effect on ovarian reserves for poor-responder patients on IVF treatment. Clinicaltrials.gov: NCT01145144.

RESUMO

To investigate the effects of silymarin on follicular development, we enrolled 40 healthy women undergoingin vitro fertilization (IVF) due to male factor infertility in this trial. They underwent ovulation induction and on a random and blind basis, patients were assigned to receive silymarin (70 mg x 3/day) or placebo from the beginning of the induction cycle. The number and quality of oocytes retrieved were evaluated and apoptosis of > or = granolusa cells was studied. There was no significant difference between the groups for mean number of follicles 18 mm (P = 0.131), mean number of oocytes retrieved (P = 0.209) or endometrial thickness (P = 0.673). However, the proportion of total apoptosis in the study group was significantly lower than in the placebo group (P = 0.032). These data suggest that administration of silymarin in IVF patients concomitantly with gonadotropin results in reduction of granolusa cell apoptosis but does not have any effect in promotion of follicular development, oocyte retrieval or endometrial thickness.

RESUMO

The aims of the present study were to examine the variability of testosterone secretion in the Virginia Opossum over a 24 h period and to develop a testosterone stimulation test that would provide an index of the prevailing testosterone biosynthetic capacity of the testes; the latter was used to clinically evaluate the efficacy of a gonadotrophin-releasing hormone agonist contraceptive. Sexually-mature captive opossums (n = 12) located in Africam Safari (Mexico) sampled every 12 h over 24 h consistently showed basal (<0.21 ng mL(-1)) blood testosterone concentrations. Intra-muscular injection of buserelin (2 microg mL(-1)) and human chorionic gonadotrophin (hCG; 1000 IU) resulted in an increase (P < 0.05) of plasma testosterone concentrations with maximal concentrations (3.9 ng mL(-1) and 5.8 ng mL(-1) respectively) occurring 120 min after injection. Plasma testosterone declined relatively rapidly to basal concentrations after 240 min with hCG but remained elevated after the same period of time with buserelin. Male opossums treated with (n = 6) and without (n = 6) a controlled-release deslorelin implant (Suprelorin; 4.7 mg deslorelin) were evaluated over a 10-week period for changes in testosterone secretion (hCG stimulation test) and sperm production (spermatorrhea). At the end of this period, the animals were hemi-castrated and their relative testicular quantitative histology compared. Testosterone concentration decreased over the course of the study in both treated and control animals (P < 0.0001) but there was no apparent effect of deslorelin on testosterone secretion, testicular histology (relative proportions of testicular cell types and seminiferous tubule diameter), or sperm production (presence of sperm in the cauda epididymis or urine).

RESUMO

The treatment of 126 patients with male sterility was analyzed. The low efficiency of therapy with hormonal and nonhormonal drugs in patients with testicular form of sterility was observed. The same patients clinically underwent general (intravenous) ozonotherapy. After one course (10 intravenous injections) stable positive clinicolaboratorial effect (increase of sperm density and qualitative characteristics of gametes) was detected in 28% patients. After 2-3 courses (with intervals of 3 months) positive dynamics was observed in almost 70% cases. Thus, general ozonotherapy should be considered as one of effective technologies of treatment in patients with male sterility.

RESUMO

The author present a few years opinion for treatment of patients with vaginal bleeding in first trimester of pregnancy and obstetrical complications with Pregnyl(Organon). The basics factors for inclusion in examination group are pregnant women in early pregnancy complicated with vaginal bleeding, with or not a pain. Overall 34 patients whose be treatment, 31 delivered lived and health child, one patient delivered baby with osteogenesis imperfecta and 2 patients the pregnancy is bracked with spontaneous abortion. The treatment with Pregnyl is very good method in patients with infertilitas, polycystosis ovarii and vaginal bleeding in early pregnancy. The doses of Pregnyl is 10,000 E i.m. (bolus dose), 5,000 E i.m. two times weekly between the first dose and 10 weeks of pregnancy, 5,000 E i.m. weekly between 10 and 14 weeks of pregnancy.

RESUMO

OBJECTIVE: To find a method without corticosteroids, aspirin or heparin for treatment of anticardiolipin antibody-positive early recurrent spontaneous abortion (AARSA). METHODS: Twenty-three patients of AARSA in the treated group were treated with Chinese herbal medicine (CHM) plus human chorionic gonadotropin and progesterone, and 18 patiens in the control group were treated with multi-vitamin only. The change of anticardiolipin antibody was determined by enzyme linked immunoabsorbent assay (ELISA). RESULTS: After treatment, anticardiolipin antibody negative converted in 20 cases (86.9%) of the treated group. The cure rate of abortion in the treated group was 82.6% (19/23), which was raised to 95% (19/20) in those patients with antibody negative conversion, while in the control group, it was 16.7% (3/18) merely, comparison between the two groups in cure rate showed significant difference (P < 0.01). CONCLUSION: CHM plus human chorionic gonadotropin and progesterone could cure AARSA effectively.
