“…The pituitary-thyroid axis hormones, including thyroid-stimulating hormone (TSH) and the thyroid hormones, control the function of the thyroid and are essential for metabolic homeostasis [10]. For example, the pituitary can increase or reduce the TSH level according to the feedback of the thyroid hormones [11]. Pituitary-gonadal axis hormones, including follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T), control the gonadal function and are essential for reproduction [12].…”

Analysis of the correlation between lipotoxicity and pituitary-thyroid axis hormone levels in men and male rats

Lipotoxicity seriously harms human health, but it is unclear whether lipotoxicity is detrimental to the pituitary. We investigated the correlation between serum triglyceride and pituitary axis hormone levels in epidemiological and animal studies. In the epidemiological study, serum thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were greater in male patients with isolated hypertriglyceridemia than in controls, whereas adrenocorticotropin (ACTH) levels were lower in the patients with hypertriglyceridemia. Pituitary hormone levels correlated with triglyceride levels, even after adjustment for potential confounders. In the animal study, male rats were fed a high-fat or control diet for 28 weeks. As the duration of high-fat feeding increased, the serum and pituitary triglyceride concentrations increased. At early times, the high-fat diet elevated serum TSH and triiodothyronine. At later times, much higher serum TSH levels coupled with reduced thyroxine were observed in the high-fat group. Serum levels of pituitary-gonadal and pituitary-adrenal axis hormones were not affected by the diet. The mRNA and protein expression of Tshβ were greater in the high-fat group than in the control group, whereas expression of Fshβ, Lhβ and Acth had no difference between the groups. Overall, serum triglyceride levels were associated with pituitary-thyroid axis hormone levels.

“…Le pan hypopituitarisme se définit par le déficit de la plupart des hormones de l'hypophyse antérieur y compris LH, FSH, ACTH, TSH et GH. Ainsi le pan hypopituitarisme entraine une hypothyroïdie, fonction corticosurrénalienne réduite et hypogonadisme et être accompagnée par la perte de poids, perte de l'appétit, faiblesse, hypotension artérielle, la fatigue, perte de mémoire, et la dépression [5, 6]. Le diagnostic différentiel d'une masse hypophysaire comprend un cancer métastatique, des hémopathies malignes, granulomatoses et infections [7].…”

L'hypotension artérielle per dialytique est une complication fréquente chez l'hémodialysé chronique. Elle est occasionnée par des facteurs liés à la séance d'hémodialyse et/ou au patient. Nous rapportons le cas d'un patient âgé de 42 ans, hémodialysé chronique sur néphropathie lithiasique depuis 5 ans. Il a rapporté des céphalées chroniques atypiques, compliquées d'une baisse progressive de l'acuité visuelle, une asthénie, une hypertrophie mammaire, et une baisse de libido. Il est référé pour une hypotension artérielle per dialytique non expliquée par les causes habituelles, dont la recherche étiologique a objectivé une insuffisance anté hypophysaire et une masse hypophysaire à l'IRM. A travers cette observation, nous montrons qu'après avoir éliminé les causes classiques d'hypotension artérielle chez l'hémodialysé, une cause endocrinienne doit être recherchée.

“…Prolactinomas are the most common hormone-secreting tumors of the pituitary gland, representing up to 40% of all pituitary tumors [14]. They present as microadenomas in 90% of cases and appear most frequently in females aged between 20 and 50 years; the sex ratio is (10 -20):1 [1] and for macroadenomas the gender ratio is roughly equivalent [1,15].…”
