Inmune-mediated inflammatory rheumatic diseases in transgender people: A scoping review

[Sex-specific aspects in rheumatology]

Women and men differ in terms of the development and manifestation of inflammatory rheumatic diseases and outcomes as well as with respect to disease perception, health behavior and response to antirheumatic treatment. Sex-specific aspects are increasingly being researched in nearly all medical disciplines to optimize treatment strategies with the aim to improve individual treatment success. This article describes sex differences that can even now be taken into account in rheumatological care.

Pain mechanisms in the transgender individual: a review

Specific Aim

Provide an overview of the literature addressing major areas pertinent to pain in transgender persons and to identify areas of primary relevance for future research.

Methods

A team of scholars that have previously published on different areas of related research met periodically though zoom conferencing between April 2021 and February 2023 to discuss relevant literature with the goal of providing an overview on the incidence, phenotype, and mechanisms of pain in transgender patients. Review sections were written after gathering information from systematic literature searches of published or publicly available electronic literature to be compiled for publication as part of a topical series on gender and pain in the Frontiers in Pain Research.

Results

While transgender individuals represent a significant and increasingly visible component of the population, many researchers and clinicians are not well informed about the diversity in gender identity, physiology, hormonal status, and gender-affirming medical procedures utilized by transgender and other gender diverse patients. Transgender and cisgender people present with many of the same medical concerns, but research and treatment of these medical needs must reflect an appreciation of how differences in sex, gender, gender-affirming medical procedures, and minoritized status impact pain.

Conclusions

While significant advances have occurred in our appreciation of pain, the review indicates the need to support more targeted research on treatment and prevention of pain in transgender individuals. This is particularly relevant both for gender-affirming medical interventions and related medical care. Of particular importance is the need for large long-term follow-up studies to ascertain best practices for such procedures. A multi-disciplinary approach with personalized interventions is of particular importance to move forward.

Hormonal Therapies in Multiple Sclerosis: a Review of Clinical Data

PURPOSE OF REVIEW

Given the potential for exogenous hormones to influence risk and course of MS, this narrative review aims to summarize current knowledge from observational and interventional studies of exogenous hormones in humans with MS.

RECENT FINDINGS

Large randomized clinical trials for combined oral contraceptives and estriol both show modest effect on inflammatory activity, with the latter showing potential neuroprotective effect. After fertility treatment, large actively treated cohorts have not confirmed any elevated risk of relapse. Preclinical data suggest that androgens, selective estrogen receptor modulators (SERMs), and selective androgen receptor modulators (SARMs) may be neuroprotective but clinical data are lacking. Gender affirming treatment, particularly estrogen in trans-women, could possibly be associated with elevated risk of inflammation. For women with MS entering menopause, hormone therapy appears safe during the appropriate menopausal window, but its long-term effects on neuroprotection are unknown. Exogenous hormones, used in varied doses and for diverse indications, have variable effects on MS risk, inflammatory activity, and neuroprotection. Large randomized trials are needed before it is possible to determine the true effect of exogenous hormones in a condition as complex as MS.

Challenges of caring for transgender and gender diverse patients with rheumatic disease: presentation of seven patients and review of the literature

PURPOSE OF REVIEW

As perspectives on sex and gender identity have evolved, there has been an increase in the practice of transgender medicine. Within rheumatology, however, there is a dearth of information about rheumatic disease in transgender and gender diverse (TGGD) individuals. This is important, as sex hormones affect the etiopathogenesis and expression of autoimmune diseases. We therefore sought to identify TGGD patients with rheumatic disease, review their clinical courses, and appraise existing literature about this population.

RECENT FINDINGS

Of 1053 patients seen at the Los Angeles County and University of Southern California Medical Center from 2019 through 2021, five transgender men and two transgender women with rheumatic disease were identified. Most patients' disease courses were not overtly impacted by gender affirming hormone therapy (GAHT). Six of seven patients had psychosocial barriers to care. Our systematic review found 11 studies with 11 transgender women and two transgender men. In 12 of 13 patients, GAHT possibly modulated the patients' rheumatic disease.

SUMMARY

Our observations suggest GAHT need not be a strict contraindication in TGGD patients with rheumatic disease. TGGD patients often face significant psychosocial barriers. Additional information about this population and empathy toward their health disparities are needed.

Rheumatoid arthritis in a transman: A new case

It concerns a transman with a mastectomy, hysterectomy and bilateral adnexectomy and in monthly treatment with testosterone, who shows a rheumatoid arthritis now in remission with low weekly doses of methotrexate orally.

Sex-Based Medicine Meets Psoriatic Arthritis: Lessons Learned and to Learn

Humorally associated autoimmune diseases generally show a female predominance whereas ankylosing spondylitis, a disease that overlaps with psoriatic arthritis (PsA), shows a male predominance. The present review ascertains the current knowledge of sex-specific differences related to psoriatic arthritis (PsA), a chronic, inflammatory condition associated with psoriasis. Sex differences may have important implications for clinical research in PsA and in terms of epidemiology (incidence, prevalence, lifetime risk, survival, and mortality), clinical, radiological, and laboratory features, and response to treatment. While nationwide surveys and large-scale databases and registries show no sex-specific differences, varying male/female ratios have been reported, ranging from 0.42 to 2.75 (comparable with those reported for psoriasis vulgaris: ranging from 0.28 to 2.38). This may reflect subtle, complex, nonlinear interactions between the biological make-up of the individual (genetic and epigenetic differences), hormonal components including menopausal status, environmental exposures including skeletal physical stressing, and psychological variables. There exists methodological heterogeneity and paucity of data concerning sex-specific differences, in terms of the specific population studied, study design, and the diagnostic criteria utilized. Harmonizing and reconciling these discrepancies would be of crucial importance in achieving the ambitious goals of personalized/individualized medicine and further standardized meta-data and Big Data could help disentangle and elucidate the precise mechanisms of underlying potential PsA sex-specific differences.
