8 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the use of the non-ergoline dopamine agonist ropinirole for the treatment of hyperprolactinemia in patients with idiopathic hyperprolactinemia and prolactinomas.
The goal of this study is to learn more about how kisspeptin, a naturally occurring hormone, affects women with high levels of prolactin (also called hyperprolactinemia). Subjects in one group will undergo blood sampling every 10 minutes over two 12-hour periods (one 12-hour period without any intervention and one 12-hour period with intravenous (IV) kisspeptin administration). Subjects in the second group will receive subcutaneous (SC) kisspeptin every 90 minutes for eight days.
Prolactin is a hormone that naturally occurs in the body. Some women taking antipsychotic medications may have high levels of prolactin in their bodies. High levels of prolactin may cause women to have problems with sex or satisfaction from sex. It may also cause women to have fewer or no menstrual periods. It may also cause the production of breast milk and may contribute to long term bone loss. In this study, the investigators are testing whether taking adding a low dose of an antipsychotic medication called aripiprazole may help improve high prolactin levels and help with sexual dysfunction or problems with menstrual periods. The investigators are also looking to see if it may slow the loss of bones. This medication has been shown to be helpful for improving symptoms of schizophrenia.
The purpose of this study is to determine whether calcium and vitamin D supplementation, over a nine-month period, optimizes bone mineralization in boys with risperidone-induced hyperprolactinemia. We hypothesize that, by the end of the stuy, children in the supplementation group will have higher bone mineral density compared to those in the placebo group.
Previous research has identified spontaneous cerebral spinal fluid leakage as a cause for spontaneous intracranial hypotension, leading to positional headache patterns. Typical magnetic resonance imaging findings include subdural fluid collections, enhancement of pachymenginges, engorgement of venous structures, pituitary hyperemia, and sagging of the brain (SEEPS). Because pituitary hyperemia has been documented in cases of spontaneous cerebral spinal fluid leakage and is known to mimic a pituitary tumor or hyperplasia, the investigators would like to like to assess the clinical manifestations and neuroimaging abnormalities of SIH patients with regard to the pituitary gland. Specifically, the investigators are looking to analyze the compression of the pituitary stalk and conduct a systemic evaluation of pituitary function in SIH patients.
The goal of this study is to learn about the role of kisspeptin in the reproductive system. Kisspeptin is a naturally occurring hormone in humans that causes the release of other hormones, including gonadotropin-releasing hormone (GnRH) in the body.
The purpose of this study is to develop a new protocol using two different types of fertility drugs that is more similar to the way the hormones act in a normal menstrual cycle (period). We are recruiting women who are trying to get pregnant through In Vitro Fertilization (IVF) who either have a high prolactin level (a hormone normally found in your blood that is produced in the brain) or have a condition known as hypothalamic amenorrhea in which one does not get regular periods due to low hormone levels. The ovaries can be stimulated with Follicle Stimulating Hormone (FSH) alone and with FSH and Luteinizing Hormone (LH). FSH causes eggs to be made while LH causes estrogen (hormone) production. The women in this study have low hormone levels and need both FSH and LH. Luveris® (LH hormone) is a new drug approved for egg production and is used in IVF. There is no set amount of LH nor a set protocol for LH use. Therefore, we are testing this new regimen. One group of women will receive a fixed dose of LH throughout their cycle while the other will decrease the dose of FSH while at the same time increasing the LH dose which is what happens in the natural menstrual cycle.
The purpose of this study is to show that amantadine might help to reduce the side effect of the medications which are prescribed to treat schizophrenia or schizoaffective disorder. High level of hormone prolactin, or hyperprolactinemia, is one of the side effects which might be developed in patients treated with the paliperidone ER or risperidone Consta. High level of prolactin might stimulate breast development, might decrease sexual desire (libido). The goals of this study are to demonstrate that amantadine lowers prolactin levels, decreases side effects, and improves psychiatric symptoms.
