Biliary Dyskinesia in Stiff Person Syndrome: An Association Between Reduced GABA Production and Gastroenteric...

Stiff person syndrome (SPS) and biliary dyskinesia are two rare but potentially debilitating conditions that can significantly impact quality of life. SPS is a rare neurological disorder characterized by muscle stiffness, rigidity, and muscle spasms that primarily affect the trunk and limbs and is associated with extra-axial manifestations involving the gastrointestinal tract. Biliary dyskinesia is a gastrointestinal disorder characterized by abnormal gallbladder emptying, leading to symptoms of intense abdominal pain, nausea, and vomiting. Despite their distinct clinical presentations, studies have suggested a possible connection between the two disorders. This link may be due to involvement of similar neurotransmitters and autoantibodies in both conditions. In this report, we present a case of biliary dyskinesia in a 58-year-old male with prior history of chronic gastrointestinal symptoms, autoimmune disease, and SPS. Given the rarity of these conditions, there is a need for increased awareness and improved diagnostic modalities to facilitate early detection and management.
