Circulating Autoantibodies Against Vasoactive Biomarkers Related to Orthostatic Intolerance in Long COVID Patients Compared to No-Long-COVID Populations: A Case-Control Study [PDF]

Biomolecules
Endothelial dysfunction mediated by elevated levels of autoantibodies against vasoactive peptides occurring after COVID-19 infection is proposed as a possible pathomechanism for orthostatic intolerance in long COVID patients.

Postoperative orthostatic intolerance following fast-track unicompartmental knee arthroplasty: incidence and hemodynamics—a prospective observational cohort study [PDF]

Journal of Orthopaedic Surgery and Research
Background Early postoperative mobilization is essential for early functional recovery but can be inhibited by postoperative orthostatic intolerance (OI). Postoperative OI is common after major surgery, such as total knee arthroplasty (TKA).

Children and adolescents with disorders of gut-brain interaction with comorbid hypermobility and orthostatic intolerance have worse outcomes. [PDF]

J Pediatr Gastroenterol Nutr
Abstract Objectives Disorders of gut–brain interaction (DGBI) affect about 40% of children and are often comorbid with hypermobility spectrum disorders (HSDs) and orthostatic intolerance (OI). However, how these comorbidities impact outcomes in pediatric DGBI is not well understood.
