Expert Opinion on Age-Related Sex Hormone Changes and Hypogonadism in People With Multiple Sclerosis: A Delphi Consensus Program.

Purpose of Review: As the life expectancy of people with multiple sclerosis (PwMS) increases, the importance of recognizing and addressing specific needs and challenges faced by those undergoing age-related sex hormone changes and hypogonadism is becoming increasingly evident. We present expert-led, practical recommendations from a consensus program that address gaps in age-related sex hormone changes and hypogonadism in PwMS not sufficiently addressed in current literature and guidelines. A multidisciplinary steering committee (SC) of 15 international experts identified 18 key clinical questions across 6 themes: climacteric symptoms in women with MS; impact of MS on the climacteric stage; impact of menopause on MS disease activity and progression; treatment and management of climacteric symptoms in women with MS; late-onset hypogonadism (LOH) in men with MS; and patient-centered care. After thorough review of the evidence from a systematic literature review, the SC formulated 18 clinical recommendations to address the questions. These recommendations were voted on by the SC and an extended faculty of 23 health care professionals from 16 countries, including 2 nurses and 1 patient association representative. Recent Findings: Consensus was reached when ≥75% of respondents expressed agreement, with a score of 7-9 on a 9-point scale. After a single voting round, all 18 recommendations reached consensus (14 reaching consensus at 90%-100% and 4 at 80%-90%). The clinical recommendations addressed the following: the potential overlap and exacerbation of MS symptoms during the climacteric stage; the need for preventive care and screening during the menopausal transition; the potential for, and a paucity of data on, differential efficacy and tolerability of MS medications in menopausal/postmenopausal women; the complex causal interplay between hormonal and/or immunologic changes and natural aging in PwMS switching to a more progressive phase of disease; consideration of behavioral/lifestyle interventions alongside pharmacologic treatments; effects of hormonal treatments on MS symptoms; and management of LOH in men with MS. Summary: These recommendations were based on a robust modified Delphi consensus approach and present a valuable framework for improved patient care. These results emphasize the need to address critical gaps in our understanding and management of PwMS undergoing age-related sex hormone changes and hypogonadism.
