In clinical practice, it is the most frequently encountered anterior pituitary disorder. However, its real prevalence is little known in Africa. The purpose of this study is to list all cases of hyperprolactinemia over the past four years and to make an inventory of the various etiologies found and their management. Methodology. This is a cross-sectional descriptive study on the files of patients who came for consultation in the internal medicine and endocrinology department with hyperprolactinemia retrospectively collected from January 2017 to December 2020. Included were patients followed or whose the diagnosis of hyperprolactinemia was established in endocrinological consultation during the study period. Results. This study recorded 26 cases of hyperprolactinemia. The female sex represented 73.08% (sex ratio M/F 0.37) and the average age was 33.92 years. The 40 - 50 age group was the most represented with 30.77%. In women, galactorrhea accounted for 73.07%, amenorrhea 57.69% of clinical pictures and infertility 23.08%. In men, infertility accounted for 7.69% of presentations, gynecomastia 11.54% and erectile dysfunction 15.38%. The duration of evolution of the signs was 4 months in 23.08% of the patients. The mean prolactinemia was 702.58 ng/ml. CT was performed in 80.85% of patients. The main etiologies were pituitary adenomas (77%). All our patients were treated with dopaminergic agonists. Cabergoline was prescribed in 77% of patients. The evolution was favorable in 96.25% of patients. Conclusion. Hyperprolactinemia is a pathology that exists in our regions. The main etiology remains pituitary adenomas and treatment with cabergoline.展开更多

Hyperprolactinemia is a major cause of infertility, and herbal remedies have been employed locally for treatment. This study was designed to investigate the effects of hydroethanolic extract of Solenostemon monostachyus on the reproductive hormones and metabolic parameters of haloperidol-induced hyperprolactinemic rats. Thirty six female albino rats were divided into 6 groups of 6 in each group. Groups A, B, C, D and E were given increasing doses （2, 3 and 4 mg/kg body weight in five-daily increments） of haloperidol by intramuscular injection for 15 days after which they were treated for another 15 days with either 2.5mg/kg body weight ofbromocriptine （group D only） or 75, 112.5 or 225mg/kg body weight of the extract （groups A, B and C, respectively）. Group F was given distilled water only. After treatment, the animals were sacrificed and blood was taken from each group for plasma analysis of the reproductive hormones and metabolic parameters. The total protein and the lipid profile （total cholesterol and HDL （high-density lipoprotein） and triglycerides were also determined. Phytochemical investigation revealed the presence of saponins, phenols, alkaloids, fiavonoids, and tannins. The result of endocrine investigation showed a dose-dependent, statistically significant reduction in prolactin and testosterone （P 〈 0.05） level by the extract with statistical significant increase （P 〈 0.05） in the levels of the follicle stimulating hormone, LH （luteinizing hormone） and estrogen. There was also a decrease in the levels of the triglycerides and total cholesterol while HDL was increased （P 〉 0.05）. It can be concluded from this study, that hydroethanolic extract has a prolactin reducing activity compared with Bromocriptine and exhibited a corresponding statistical significant difference in other reproductive hormones, with no detectable alteration on metabolic parameters such as＂ albumin, total cholesterol, and high density lipoprotein.展开更多

The old pattern of simply using bromocryptine to treat the disease has been changed. Most of the cases reported in this paper were primary hyperprolactinemia, with other primary diseases excluded. As TCM treatment produces definite therapeutic effects with few side-effects, the methods above reported are worth recommending.展开更多
