The Effect of Overweight/Obesity on Cutaneous Microvascular Reactivity as Measured by Laser-Doppler Fluxmetry: A Systematic Review

Introduction: We sought to determine by systematic review the independent effect of overweight/obesity on cutaneous microvascular reactivity in adults as measured by laser-Doppler fluxmetry. Methods: CINAHL Complete, SPORTSDiscus, Embase, Medline, and Cochrane Library were searched until March 2024...

description Introduction: We sought to determine by systematic review the independent effect of overweight/obesity on cutaneous microvascular reactivity in adults as measured by laser-Doppler fluxmetry. Methods: CINAHL Complete, SPORTSDiscus, Embase, Medline, and Cochrane Library were searched until March 2024 to identify studies investigating cutaneous microvascular reactivity in an overweight/obese but otherwise healthy group versus a lean/healthy weight. Reporting is consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Quality appraisal of included studies was performed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. Results: Nineteen eligible articles reported on 1847 participants. Most articles reported impaired cutaneous microvascular reactivity in cohorts with overweight/obesity compared to cohorts with lean/healthy weight. Investigating reactivity via post-occlusive reactive hyperaemia (PORH) and iontophoresis of acetylcholine (ACh) has shown significance. No significant differences were reported between groups in response to local heating or to iontophoresis of methacholine or insulin, while findings of the effect of obesity on iontophoresis of sodium nitroprusside (SNP) were mixed. Conclusions: The pathophysiology of impaired cutaneous microvascular reactivity in overweight/obesity requires further investigation; however, impaired function of vasoactive substances, endothelial dysfunction, sensory nerves, and calcium-activated potassium channels may be implicated. Identifying these impaired microvascular responses should inform possible therapy targets in overweight and obesity.activated potassium channels may be implicated. Identifying these impaired microvascular responses should inform possible therapy targets in overweight and obesity.
