[Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases].

Beijing Da Xue Xue Bao Yi Xue Ban 2022 Apr;54(2):369-375

Department of Medical Oncolo1. Department of Medical Oncology and Radiation Sickness, Peking University Third Hospital, Beijing 100191, China.

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases SUMMARY Programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) have been widely used in lung cancer treatment, but their immune-related adverse events (irAEs) require intensive attention. Pituitary irAEs, including hypophysitis and hypopituitarism, are commonly induced by cytotoxic T lymphocyte antigen 4 inhibitors, but rarely by PD-1/PD-L1 inhibitors. Isolated adrenocorticotropic hormone(ACTH) deficiency (IAD) is a special subtype of pituitary irAEs, without any other pituitary hormone dysfunction, and with no enlargement of pituitary gland, either.

Maternal prolactin levels during late pregnancy and nurturing behavior of offspring in mice.

Dev Psychobiol 2022 03;64(3):e22264

Department of Integrative Physiology, Gunma University Graduate School of Medicine, Maebashi, Japan.

Elucidating the mechanisms underlying nurturing and neglect behaviors is meaningful but challenging. Recently, we found that CIN85-deficient mice had reduced pituitary hormone prolactin secretion during late pregnancy, and their pups later showed an inhibited nurturing behavior. To examine whether this phenomenon could be reproduced in normal mice and not just CIN85-deficient mice, we investigated the nurturing behavior of offspring born to mothers whose blood prolactin levels had been reduced by bromocriptine administration during late pregnancy.

The aberrant expression of CD45 isoforms and levels of sex hormones in systemic lupus erythematosus.

Clin Rheumatol 2022 Apr 22;41(4):1087-1093. Epub 2022 Jan 22.

Department of Histology and Embryology, Shantou University Medical College, Shantou, 515041, Guangdong Province, China.

Introduction: Systemic lupus erythematosus (SLE) is a common autoimmune disease with significant gender bias in women, and sex hormones are considered to play an important role in the regulation of immune activity. The CD45 isoforms generated through alternative splicing of mRNA identify different functional status of lymphocytes and also are suggested as a biomarker for assessing the progression of SLE, while the modulation of CD45 expression in SLE patients is not clear.

Methods: In this study, the peripheral blood sera of 46 SLE patients and 15 health individuals were collected for detecting the levels of sex hormones and immune associated factors. Read More

Unique Transcriptomic Changes Underlie Hormonal Interactions During Mammary Histomorphogenesis in Female Pigs.

Endocrinology 2022 03;163(3)

Department of Animal Science, University of California, Davis, Davis, California 95616, USA.

Successful lactation and the risk for developing breast cancer depend on growth and differentiation of the mammary gland (MG) epithelium that is regulated by ovarian steroids (17β-estradiol [E] and progesterone [P]) and pituitary-derived prolactin (PRL). Given that the MG of pigs share histomorphogenic features present in the normal human breast, we sought to define the transcriptional responses within the MG of pigs following exposure to all combinations of these hormones. Hormone-ablated female pigs were administered combinations of E, medroxyprogesterone 17-acetate (source of P), and either haloperidol (to induce PRL) or 2-bromo-α-ergocryptine. Read More

Lipidized Prolactin-Releasing Peptide as a New Potential Tool to Treat Obesity and Type 2 Diabetes Mellitus: Preclinical Studies in Rodent Models.

Front Pharmacol 2021 18;12:779962. Epub 2021 Nov 18.

Institute of Organic Chemistry and Biochemistry, Czech Academy of Sciences, Prague, Czech.

Obesity and type 2 diabetes mellitus (T2DM) are preconditions for the development of metabolic syndrome, which is reaching pandemic levels worldwide, but there are still only a few anti-obesity drugs available. One of the promising tools for the treatment of obesity and related metabolic complications is anorexigenic peptides, such as prolactin-releasing peptide (PrRP).

Department of Internal Medicine, Institute of Endocrine Research, Yonsei University College of Medicine, Seoul 03722, Korea.

Predicting dopamine agonist resistance in patients with macroprolactinoma is essential for clinicians to prevent treatment failure and subsequent complications such as medication-induced cerebrospinal fluid (CSF) rhinorrhea. We evaluated the features of patients with cabergoline resistance and CSF rhinorrhea in patients with prolactinomas with prolactin levels ≥1000 ng/mL. A total of 140 patients who were newly diagnosed with prolactinoma secreting only prolactin ≥1000 ng/mL and treated with cabergoline for the first time were included in this study. Read More

High prolactin levels in dihydropteridine reductase deficiency: A sign of therapy failure or additional pathology?

JIMD Rep 2021 Sep 29;61(1):48-51. Epub 2021 Jun 29.

Division of Metabolic Diseases, Department of Medicine-DIMED, University Hospital University of Padova Padova Italy.

We report the case of a 22-year-old man with a diagnosis of dihydropteridine reductase (DHPR) deficiency who progressively developed movement disorders and epilepsy. Despite L-Dopa supplementation the patient continued to show high prolactin levels, with a discrepancy between the neurological clinical picture and the hormonal biochemical levels. For this reason, other potential causes were ruled out by performing a cerebral magnetic resonance imaging, which demonstrated a solid lesion in the pituitary gland strongly suggestive of a prolactinoma.
