Active clinical trials for "Hyperprolactinemia"

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.

The overall goal of this study will be to assess and monitor the adherence to and effectiveness of the new prescribing guidelines for cabergoline. Specific objectives will be to assess: 1. The indication for use of cabergoline (Parkinson, hyperprolactinemia, other) 2. Prior treatment strategies in patients who start cabergoline treatment for Parkinson's Disease 3. The percentage of cabergoline users who are prescribed doses above 3 mg per day 4. Whether cabergoline users are monitored by echocardiography prior and during treatment. 5. The incidence and prevalence of valvular fibrosis

Hyperprolactinaemia is a common side effect of some antipsychotics (APS), including some atypicals. Clinical consequences of hyperprolactinaemia are broad including amenorrhea, galactorrhea, tender breasts, gynecomastia and sexual dysfunction. Less known but also present is the increased cardiovascular risk, specially in women, disorders of osteoporotic type and a potential increased risk of breast and prostate cancer. Despite this growing evidence, there are no consistent published data in order to adopt evidence-based decisions that may be beneficial for the patient. This naturalistic observational 6 months follow-up study on patients with APS-induced hyperprolactinemia aims to obtain more information about the switching approach in cases of hyperprolactinemia secondary to APS and to better establish the role of switching to quetiapine (APS not related with the increase prolactin levels) in this problem.

The aim of the present cohort retrospective study is to explore the effect of antipsychotics on periodontal health and the possible effect of antipsychotic-induced hyperprolactinemia as a risk factor for periodontal disease progression in schizophrenic patients. The study population consisted of three groups: Group A (n = 21): schizophrenic patients who have been taking "prolactin inducing" antipsychotics for at least 1 year, Group B (n = 21): schizophrenic patients who have been taking "prolactin sparing" antipsychotics for at least 1 year and Group C (n = 22): newly diagnosed schizophrenic patients and/or patients who did not receive any psychiatric treatment for at least 1 year. The study groups underwent an assessment of periodontal condition in terms of pocket depth (PD), clinical attachment loss (CAL), gingival recession, tooth mobility, and bleeding on probing (BOP). Also, bone mineral density was evaluated using DEXA scans and the serum prolactin level was measured by automated immunoassay.

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of reproductive-age women. According to Rotterdam 2003 criteria: at least two of three criteria are met, hyperandrogenism, chronic anovulation, and polycystic ovary. PCOS will cause irregular menstrual cycle, infertility, acne, hirsutism, obesity, or/and metabolic syndrome, diabetes that may increase risk of cardiovascular disease. Hyperprolactinaemia is also a common problem in reproductive aged women. Both hyperprolactinaemia and PCOS had endocrine disorder and irregular menstrual cycle. Investigators hope to collect clinical data from PCOS and prolactinemia patients followed in Wang Fang hospital for many years in endocrinological and metabolical aspects for comparison. Investigators at the same time would like to understand more about other similarities and differences between these two endocrinological dysfunction for future study.

Hyperprolactinaemia and thyroid disorders can significantly reduce fertility by causing ovulatory dysfunction. There is no evidence to suggest treatment of hyperprolactinaemia in the presence of regular ovulatory menstruation will improve fertility. However, anecdotal observation of practice at UHCW NHS Trust suggested that dopamine agonists are often prescribed irrespective of whether symptoms of hyperprolactinaemia are present. The aim of the study was to establish the prevalence of hyperprolactinaemia and incidence of subclinical hypothyroidism in patients undergoing subfertility investigations at UHCW NHS Trust. Also, to examine management of patients with hyperprolactinaemia and a normal pituitary MRI scan, and explore the trends in treatment; and finally, to explore how this could improve reproductive services. 107 patients were identified as having a high prolactin reading between January 2014 and January 2017. Hospital records were examined for patient demographics, relevant blood and scan results, medical history, any treatment, and treatment outcomes. The prevalence of hyperprolactinaemia was 23%. 20.6% of patients had suboptimal thyroid function and were started on levothyroxine. Prolactin levels, and presence of relevant symptoms, only had a partial bearing on whether dopamine agonists were used in those with normal pituitary MRI results (or where no scan was performed). The use of dopamine agonists appeared to correlate with assisted conception and a lower incidence of birth complications (inc. miscarriage, prematurity), though the significance of this was limited by the size of the dataset. Dopamine agonists often appeared to be used in more complex patients, rather than exclusively those with a higher prolactin reading and/or the presence of related symptomatology. Patients frequently underwent a pituitary MRI scan in the absence of symptoms, contrary to evidence. The findings suggest that less patients should be scanned and less treated with dopamine agonists. A health economics evaluation study would be useful to elucidate the potential cost saving this could represent. It may be better to prioritise optimisation of thyroid function, particularly when noting the similarities in the prevalence of suboptimal thyroid function and that of hyperprolactinaemia.

The purpose of this study is to investigate the effects of chronic elevated levels of Prolactin on metabolism and insulin sensitivity by studying patients with hyperprolactinemia before and after treatment.

To assess the association between cabergoline and other dopamine agonists (DAs), and symptomatic, diagnosed serious cardiopulmonary disorders, including: Cardiac valve regurgitation Diffuse Pleural/pulmonary thickening and pericardial and retroperitoneal fibrosis Heart failure Total, cardiac and respiratory mortality

The purpose of this study is to clarify the nature of macroprolactin which has recently been highlighted because of the high prevalence and a diagnostic pitfall of hyperprolactinemia. The results of this study are beneficial for the patients to whom unnecessary medications and unnecessary radiological examinations have been performed. We used the remained serum samples taken for routine prolactin determination during the past several years. Since the blood was basically taken to examine the causes of hyperprolactinemia and only remained serum samples were used for this study, the Ethics Committee of Kobe City General Hospital judged that it was not required to obtain approval number.
