Sex-Related Differences in Pharmacological Response to CNS Drugs: A Narrative Review.

J Pers Med 2022 May 31;12(6). Epub 2022 May 31.

Faculty of Medicine, "Victor Babeş" University of Medicine and Pharmacy, 2 Eftimie Murgu Street, 300041 Timisoara, Romania.

In the last decades, both animal and human studies have neglected female subjects with the aim of evading a theorized intricacy of feminine hormonal status. However, clinical experience proves that pharmacological response may vary between the two sexes since pathophysiological dissimilarities between men and women significantly influence the pharmacokinetics and pharmacodynamics of drugs. Sex-related differences in central nervous system (CNS) medication are particularly challenging to assess due to the complexity of disease manifestation, drugs' intricate mechanisms of action, and lack of trustworthy means of evaluating the clinical response to medication.

Cross-reactivity in assays for prolactin and optimum screening policy for macroprolactinaemia.

Clin Chem Lab Med 2022 Jun 17. Epub 2022 Jun 17.

Clinical Biochemist, retired, Chiltern House, Bury St Edmonds, Suffolk, UK.

Objectives: Macroprolactin cross-reacts in immunoassays for prolactin causing apparent hyperprolactinaemia (macroprolactinaemia) and consequent misdiagnosis and mismanagement of patients.

Methods: We determined the prevalence of macroprolactinaemia using prolactin immunoassays with reported "high" (Tosoh) or "low" cross-reactivity (Roche) with macroprolactin. We additionally modelled the effects of increasing the screening threshold on workload and sensitivity in the detection of macroprolactinaemia. Read More

Interference by macroprolactin in assays for prolactin: will the Diagnostics Regulation lead to a solution at last?

Clin Chem Lab Med 2022 Jun 15. Epub 2022 Jun 15.

Department of Investigative Endocrinology, St. Vincent's University Hospital, Elm Park 4, Dublin, Ireland.

Cross reactivity with high molecular weight complexes of prolactin known as macroprolactin is a common cause of positive interference in assays for serum prolactin. All prolactin assays currently available are affected with 5-25% of results indicating hyperprolactinaemia falsely elevated due to macroprolactinaemia - hyperprolactinaemia due to macroprolactin with normal concentrations of bioactive monomeric prolactin. Macroprolactinaemia has no pathological significance but, if it is not recognised as the cause, the apparent hyperprolactinaemia can lead to clinical confusion, unnecessary further investigations, inappropriate treatment and waste of healthcare resources.

Etiology and management of amenorrhea in adolescent and young adult women.

Curr Probl Pediatr Adolesc Health Care 2022 05 4;52(5):101184. Epub 2022 May 4.

Division of Adolescent Medicine, Cohen Children's Medical Center, Northwell Health, 410 Lakeville Road, Suite 108, New Hyde Park, NY 11042, United States; Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hempstead, NY, United States.

In this article, we will review the etiology and management of amenorrhea in adolescent and young adult women, beginning with the diagnostic work-up and followed by etiologies organized by system. Most cases of amenorrhea are caused by dysfunction of the hypothalamic-pituitary-ovarian (HPO) axis, which is the major regulator of the female reproductive hormones: estrogen and progesterone.  We begin by reviewing hypothalamic etiologies, including eating disorders and relative energy deficiency in sport.

Dominique Maiter

Ann Endocrinol (Paris) 2022 Jun 5;83(3):164-167. Epub 2022 May 5.

Service d'Endocrinologie et Nutrition, UCLouvain Cliniques Universitaires Saint-Luc, avenue Hippocrate 10, 1200 Bruxelles, Belgium. Electronic address:

Mild-to-moderate hyperprolactinemia is a frequent finding in young women presenting with infertility. Prolactin (PRL) concentration should be determined accurately, whether or not the patient has other symptoms suggestive of excess PRL such as galactorrhea or menstrual cycle disorder. After confirmation of persistent hyperprolactinemia on a second blood sample (avoiding conditions known to raise prolactin) and exclusion of macroprolactinemia, prolactinoma and other identifiable non-tumoral causes of hyperprolactinemia must be ruled out.

Med J Islam Repub Iran 2021 15;35:167. Epub 2021 Dec 15.

Department of Endocrinology and Metabolism, Zahedan University of Medical Sciences, Zahedan, Iran.

Prevalence and clinical significance of hyperprolactinemia in subclinical hypothyroidism have been reported in few studies. The upper limit of the normal range for TSH used to diagnose subclinical hypothyroidism is a matter of controversy. Some experts believe that the upper limit of the normal TSH range should be reduced from 4. Read More

Antipsychotic polypharmacy and adverse drug reactions among adults in a London mental health service, 2008-2018.

Psychol Med 2022 Apr 29:1-8. Epub 2022 Apr 29.

Division of Psychiatry, University College London, London, UK.

Background: Antipsychotic polypharmacy (APP) occurs commonly but it is unclear whether it is associated with an increased risk of adverse drug reactions (ADRs).

A diversity outbred F1 mouse model identifies host-intrinsic genetic regulators of response to immune checkpoint inhibitors.

Oncoimmunology 2022 20;11(1):2064958. Epub 2022 Apr 20.

Department of Oncology, Karmanos Cancer Institute, Wayne State University, Detroit, MI, USA.

Immune checkpoint inhibitors (ICI) have improved outcomes for a variety of malignancies; however, many patients fail to benefit. While tumor-intrinsic mechanisms are likely involved in therapy resistance, it is unclear to what extent host genetic background influences response. To investigate this, we utilized the Diversity Outbred (DO) and Collaborative Cross (CC) mouse models. Read More

In this study, we designed and synthesized a novel series of multi-receptor ligands as polypharmacological antipsychotic agents by using a multi-receptor affinity strategy. Among them, 3w combines a multi-receptor mechanism with high mixed affinities for D, 5-HT, 5-HT and H receptors, and low efficacy at the off-target receptors (5-HT, H and α receptor) and human ether-à-go-go-related gene (hERG) channel. In addition, compound 3w exhibits favorable antipsychotic drug-like activities in assessment. Read More
