Skin Response to Delayed Hypersensitivity Testing in Persons With Unilateral Stroke-related Paresis: Implications for People With Spinal Cord Injury

Abstract

Background: Vaccination rates among individuals with spinal cord injury (SCI) could be improved if it can be shown that vaccination performed on insensate areas is effective. This would eliminate the the risk of discomfort and soreness at the injection site.Objective: To determine whether immune responsiveness varies between areas with intact and impaired innervation in patients with stroke-related paresis.Design: Prospective trial in which each subject served as his or her own control. Setting: Rehabilitation wards and long-term care units at a Veterans Affairs Medical Center.Patients: Individuals with a history of cerebrovascular accident (CVA) affecting 1 side of the body.Methods: The Multitest cell-mediated immunity (CMI) and purified protein derivative (PPD) of tuberculin were administered intradermally to each arm of each subject. Main Outcome Measures:Total millimeters of induration in response to either test and positive vs negative responses to either test were compared between the 2 arms of each subject.Results: Response to delayed hypersensitivity testing did not differ between the arms affected and unaffected by CVA in each subject, and the time since CVA also did not affect the magnitude of the skin response.Conclusions: Skin testing for delayed hypersensitivity can be effectively administered in the paretic arms of persons who have experienced CVA. Although this study was performed in patients with stroke-related impairment, it has implications for vaccine administration in individuals with SCI-related neurologic deficits.J Spinal Cord Med. 2007;30:362-365

“…A resposta de hipersensibilidade do tipo tardia (HTT) é induzida por injeções intradérmicas de antígenos e representam um protocolo padrão para avaliar a resposta imune mediada por célula (Lopez et al, 2009;Rosenstreich, 1993;Thongngarm et al, 2006;Trautner et al, 2007;Tsicopoulos et al, 1999;Vukmanovic-Stejic et al, 2006). Em humanos, a reação de HTT foi inicialmente (Rosenstreich, 1993;Thongngarm et al, 2006;Vukmanovic-Stejic et al, 2006).…”
