Filter by:This study aims to explore the optimal dose of pegylated recombinant human growth hormone (PEG-rhGH) injection to treat children of Turner syndrome (TS), preliminarily evaluate its safety and efficacy and provide scientific and reliable evidence for the medication dosage in Phase 3 clinical trial.
There is a high incidence of women suffering from Primary Ovarian Insufficiency (POI). One of the most common treatments for POI is hormone replacement therapy (HRT), but HRT doesn't work well, and it has been shown to increase the risk of blood clots in the veins, ovarian cancer, and breast cancer. The ability of MSCs to differentiate into oocyte-like cells has been previously documented. Herein the purpose of this work is to evaluate the therapeutic potential of cell therapy in women suffering from POI.
The goal of this study is to determine safety and tolerability and of intra-ovarian injection of adipose derived stromal cell in women with premature ovarian failure and to study the preliminary efficacy ADSCs intra ovarian injection on ovarian function improvement.
In this study, the investigators used the newly developed technique i.e. in vitro activation of dormant follicles (IVA) to promote ovarian follicle growth much more efficiently than natural, in vivo process for women with Primary Ovarian Insufficiency (POI).Firstly, the investigators remove one ovary under laparoscopic surgery. Then, we dissect ovarian cortex from the ovarian medulla. The ovarian cortex is cut into small cubes and cultured with medium containing drugs to activate dormant follicles. After 2 days of culture, the ovarian cubes are transplanted mainly beneath the membrane of Fallopian tubes under laparoscopic surgery. The ovarian cortex could be cryopreserve for future re-transplantation and in some cases, for convenience to arrange second surgery. Once frozen, the ovary can be preserved semipermanently. After transplantation, patients receive ultrasound monitoring together with measurement of serum hormone levels for 10-12 months. If growing follicles are detected, follicle growth is stimulated by injection of hormones (gonadotropins). Using the same "ovum pick up" approach used in IVF (in vitro fertilization), we pick up oocytes from the follicles and fertilize them. Fertilized eggs are cultured and then cryopreserved for future embryo transfer. Currently, we recurit patients diagnosed with POI, or Ovarian resistance syndrome (ORS). The procedure can also be: Only superficial cut of the ovarian cortex by laparoscopy or laparotomy, without taking ovary outside or cultured with medium.
To collect data of clinical, biochemical and 3D-ultrasonographic parameters of a population of fertile women aged 18-55 in order to design a new algorithm able to predict ovarian age and to evaluate the reliability of a multimodal diagnostic evaluation of ovarian age in term of both reproductive prognosis and distance to menopause following the guidelines of the Standards for Reporting of Diagnostic Accuracy initiative (STARD)
This is an observational epidemiologic multicentric study of follow-up a cohort for described the situation of patients with primary ovarian insufficiency in public population with respect to the age of apparition the primary ovarian insufficiency . iPOI (Investigators in premature ovarian insufficiency): M. Guinot, B. Roca, J. Tomás, P. Escamilla, J. Hernández, P. Llaneza, N. Mendoza Ladrón de Guevara, B. Otero García, I. Ñiguez, A. Castro, L. Baquedano, P. Romero, S. Sánchez.
Stem cells (SC) are the foundation cells for every organ, tissue and cell in the body. They are undifferentiated "blank" cells that do not yet have a specific function. Under proper conditions, they begin to develop into specialized tissue and organs. They are self-sustaining and can replicate themselves for long periods of time. They have the remarkable potential to develop into many different cell types in the body. They serves as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the person is still alive. Premature ovarian failure (POF) is the loss of ovarian function in women less than 40 years. It is associated with sex steroid deficiency, amenorrhea, infertility and elevated serum gonadotropins. POF occurs in 1 % of women. In majority of cases the underlying cause is not identified. Management essentially involves hormone replacement and infertility treatment. This work aimed to evaluate the therapeutic potential of Autologous MSC transplantation in women suffering from Premature Ovarian Failure.
Premature ovarian failure (POF), also known as premature ovarian insufficiency, primary ovarian insufficiency (this is the most accurate term as some women may still conceive), premature menopause, hypergonadotropic hypogonadism is defined as failure of the ovary to function adequately in a woman younger than 40 years, in its role either as an endocrine organ or as a reproductive organ, a condition characterized by amenorrhea, hypoestrogenism, and elevated serum gonadotropin levels (which demonstrate that the ovaries are no longer responding to circulating FSH by producing estrogen and developing fertile eggs) in women younger than 40 years. This condition occurs in approximately 1% of women and it has important physical and psychological consequences/impact in those patients. The purpose of this study is to investigate the role of the transplantation of bone marrow derived stem cells into ovarian tissue for treatment of premature ovarian failure and to assess their ability to differentiate into germ cells.
Premature ovarian failure (POF) refers the occurrence of amenorrhoea, elevated serum gonadotrophins and hypoestrogenism levels in female before the age of 40. It has important physical and psychological consequences/impact in those patients. Premature ovarian failure (POF) is currently managed by non-physiological sex steroid regimens which are inadequate at optimizing uterine characteristics. Human umbilical cord mesenchymal stem cells (hUCMSCs) and human cord blood mononuclear cells (hCBMNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy for POF. In this study, the safety and efficacy of hUCMSCs and hCBMNCs transplantation combined with Hormone Replacement Therapy will be evaluated in patients with Premature Ovarian Failure. Participants will be followed for an expected average of 48 weeks.
The goal of this study is to compare the features of Turner syndrome in girls who are diagnosed before birth because of fetal concerns versus those who are diagnosed when their mother has an amniocentesis for another reason.
