[Comment on the article: "Neutrophil-lymphocyte ratio as predictor of mortality in patients with necrotizing fasciitis"].

The neutrophil-to-lymphocyte ratio (NLR) is a tool used to assess the balance between the inflammatory state and the immune response, as it is associated with levels of proinflammatory cytokines. It is widely employed as a prognostic and mortality biomarker in various diseases, both infectious and oncological, such as necrotizing fasciitis, one of the leading severe infections of soft tissues and skin, whose significance lies in timely diagnosis and effective treatment.
