Parasites and Skin: Complex Interactions and Innovative Solutions

Abstract

Parasitic skin infections, caused by organisms such as lice, scabies mites, and helminths, represent a significant clinical and research challenge due to their diverse clinical manifestations and potential to cause severe health complications. The skin, as the body’s primary barrier, provides an ideal environment for these parasites, which exploit its immune interactions and surrounding microbial ecosystem. This review synthesizes recent advances in understanding the epidemiology, pathogenesis, and management of these infections, while introducing novel hypotheses to guide future investigations. Current diagnostic tools include microscopic examination and molecular testing, while treatments range from topical agents like permethrin to oral medications such as ivermectin. However, these approaches often fall short in addressing issues such as drug resistance, recurrent infections, and the complex life cycles of parasites. Three hypotheses are proposed: The skin microbiome may modulate parasite virulence through microbial competition, epigenetic changes induced by parasitic infections could influence chronic inflammation and immune evasion, and skin-specific immune memory might be harnessed to prevent reinfection. Looking ahead, the integration of advanced technologies such as artificial intelligence, clustered regularly interspaced short palindromic repeats-based interventions, and multi-omics approaches holds transformative potential for improving diagnostics, treatment, and prevention. Drawing on recent studies to bridge current knowledge with innovative, evidence-based ideas, this article emphasizes the need for interdisciplinary strategies to overcome existing limitations. By exploring these emerging insights and future directions, the review aims to inspire researchers and clinicians to address the persistent burden of parasitic skin infections with renewed focus and creativity.
