Decreased Neutrophil-to-lymphocyte Ratio in Patients with Vitiligo: National Data Analysis.

Vitiligo is characterized by depigmented skin lesions involving melanocyte defects and immune dysregulation. Haematological markers like neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been explored in various skin disorders. Given vitiligo's proposed pathogenesis, we hypothesized differences in NLR and PLR in vitiligo patients compared to controls.

Hematological Markers in Children and Adults with Atopic Dermatitis: A Retrospective Cohort Study.

Introduction: Atopic dermatitis (AD) is a common chronic skin disease with an inflammatory pathophysiology that includes the activation of the innate and adaptive immune systems. We aimed to investigate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), eosinophil-to-lymphocyte ratio (ELR), and eosinophil-to-neutrophil ratio (ENR) in AD patients, according to age and disease severity.

Methods: This is a retrospective, population-based cohort study conducted between the years 2005 and 2020, comparing hematological markers of AD patients and sex-age-ethnicity-matched controls.

Association of hematological ratios with psoriasis: a nationwide retrospective cohort study.

Background: Psoriasis is a common skin disorder linked to systemic inflammation and immune dysregulation. It is believed to involve activated T cells and neutrophils. Recent research has highlighted the potential role of hematological ratios, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), eosinophil-to-lymphocyte ratio (ELR), eosinophil-to-neutrophil ratio (ENR), and eosinophil-to-monocyte ratio (EMR), as markers for inflammatory skin diseases, including psoriasis.
