Acceptability and Feasibility of a Tai Chi/Qigong Intervention for Older People Living With HIV.

Tai chi/qigong (TCQ) is a low impact, meditative movement with breathwork that may benefit people with HIV (PWH) over 50 years old. This study is a feasibility clinical trial of a remote TCQ intervention for older PWH. Participants (n = 48) were recruited via clinic sites and social media and randomized to a TCQ, sham qigong, or wait-list control group. The 12-week intervention included fourteen 45-60-minute sessions. Acceptability (satisfaction, attitudes, practice, attendance) and feasibility (retention rate, adverse events, remote delivery) data were surveyed. Overall retention rate was 72.9%, but 81.2% for the TCQ group. Most TCQ participants attended at least 10 sessions (62.5%) and were practicing TCQ after 2 weeks (72.7%). Over 92% of TCQ participants reported satisfaction and positive attitudes and preferred remote versus in person delivery (63.6%). Two mild intervention related adverse events occurred. Findings suggest that a remote TCQ intervention is acceptable, feasible, and safe among older PWH.

RESUMEN: Tai chi/qigong (TCQ) es un movimiento meditativo de bajo impacto con ejercicios de respiración que puede beneficiar personas que viven con VIH (PVV) mayores de 50 años. Este estudio es un ensayo clínico de viabilidad que evalúa una intervención de TCQ administrada remotamente para personas mayores que viven con VIH. Participaron personas (n = 48) reclutadas en clínicas y redes sociales, asignadas aleatoriamente a un grupo de TCQ, qigong falso, o control en lista de espera. La intervención duró 12 semanas con catorce sesiones de 45 a 60 minutos. Se encuestaron datos sobre aceptabilidad (satisfacción, actitudes, práctica, asistencia) y viabilidad (retención, eventos adversos, entrega remota). La tasa de retención general fue del 72,9%, pero del 81,2% para el grupo de TCQ. La mayoría de los participantes de TCQ asistieron a al menos 10 sesiones (62,5%) y continuaron practicando después de 2 semanas (72,7%). La satisfacción y las actitudes positivas hacia la intervención fueron reportadas por más del 92% de los participantes de TCQ quienes prefirieron la participación remota contra clases en persona (63,6%). Dos eventos adversos leves relacionados con la intervención ocurrieron. Los resultados sugieren que una intervención de TCQ administrada de forma remota es aceptable, viable y seguro para personas mayores que viven con VIH.

IL-33 and IL-10 Serum Levels Increase in MCI Patients Following Homotaurine Treatment.

Homotaurine is a potential therapeutic compound for treatment of Alzheimer's disease (AD), but its efficacy is still under investigation. Emerging data have shown that other than neuroprotective, homotaurine is endowed with anti-inflammatory activities, though with still unclear underlying mechanisms. Inflammation plays a critical role in the pathogenesis of AD and we previously suggested that homotaurine supplementation in patients with amnestic mild cognitive impairment (MCI) plays beneficial effects associated to a decrease in the circulating levels of the pro-inflammatory cytokine IL-18. Here we report that MCI patients supplemented with homotaurine for 12 months show elevated serum levels of IL-10 and IL-33, as compared to baseline, in addition to the described IL-18 decrease. Furthermore, we observed a significant positive correlation between IL-10 and IL-33 levels after treatment but not at the baseline, underlining the effectiveness of the compound in modulating both cytokines in an inter-related fashion and in regulating the pro/anti-inflammation balance. Furthermore, the elevation of both IL-10 and IL-33 is significantly associated with an improvement of episodic memory of treated patients, as measured by the Delayed Verbal Ray Test. In conclusion, our results confirm that homotaurine treatment exerts an overall anti-inflammatory action in MCI patients, based not only on the down-regulation of pro-inflammatory IL-18, but also on up-regulation of the anti-inflammatory IL-33 and IL-10 cytokines, which in turn are associated with an amelioration of patient's cognitive functions. Future studies should be addressed to investigate the molecular mechanisms of homotaurine anti-inflammatory activity and its therapeutic exploitation in early AD.
