SPS is thought to be an autoimmune disease with a prominent feature of antibodies against glutamic acid decarboxylase (GAD). GAD is responsible for the enzymatic conversion of glutamic acid (glutamate) into the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). Reduced GABA activity leads to increased excitability in the central nervous system, resulting in muscle rigidity and spasms characteristic of SPS. While SPS is rare, anti-GAD antibodies seen in SPS are also seen in the much more common autoimmune disease, type 1 diabetes (T1D). There is evolving research showing that the anti-GAD antibodies of T1D are produced in response to the presence of mycobacterial heat shock protein 65 (mHSP65), and the mHSP65 is produced in response to an occult infection by a bacterium, Mycobacterium avium subspecies Paratuberculosis (MAP). Humans are broadly exposed to MAP in food, water, and air. There are linear and conformational similarities between the epitopes of GAD and mHSP65. This article proposes that MAP is also an infectious trigger for SPS. Dehydroepiandrosterone (DHEA) is a principal component of the steroid metabolome; it plateaus in young adults and then steadily declines. Bromo-epi-androsterone (BEA) is a potent synthetic analog of DHEA; unlike DHEA, it is non-androgenic, non-anabolic, and an effective modulator of immune dysregulation. BEA is also an anti-infective agent and has been shown to benefit mycobacterial infections, including tuberculosis and leprosy. With the immune stabilizing capacity of BEA as well as its anti-mycobacterial properties, there is reason to believe that a randomized clinical trial with BEA may be beneficial for SPS.<\/jats:p>","DOI":"10.3390\/microorganisms13040824","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T10:47:41Z","timestamp":1744282061000},"page":"824","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Proposing Bromo-Epi-Androsterone (BEA) for Stiff Person Syndrome (SPS)"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4301-6101","authenticated-orcid":false,"given":"Coad Thomas","family":"Dow","sequence":"first","affiliation":[{"name":"McPherson Eye Research Institute, University of Wisconsin-Madison, Madison, WI 53705, USA"},{"name":"Protibea Therapeutics, LLC., Naples, FL 34105, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"300","DOI":"10.1016\/S0025-6196(12)61012-X","article-title":"Stiff-man syndrome","volume":"66","author":"McEvoy","year":"1991","journal-title":"Mayo Clin.
