The aim of this study is to elucidate the relationship between 2 different types of severity-indicating parameters (i.e. between subjective and objective severity-indicating parameters in patients with atopic dermatitis. The disease severity of 55 patients with atopic dermatitis was assessed using 7 subjective parameters indicating severity, including visual analogue scale for itch, Patient-Oriented Eczema Measure, 5-D itch scale, Dermatology Life Quality Index, Eczema Area and Severity Index, body surface area, and Investigator Global Assessment, and 8 objective parameters indicating severity, including eosinophil relative count, neutrophil-to-lymphocyte ratio, lactate dehydrogenase, and thymus and activation-regulated chemokine. Five subjective parameters reflecting itch correlated significantly with eosinophil relative count, but not with neutrophil-to-lymphocyte ratio. In contrast, 2 subjective parameters, mainly reflecting the degree of inflammation and area of affected regions, correlated significantly with neutrophil-to-lymphocyte ratio. The eosinophil relative count may correlate with the degree of itch, while the neutrophil-to-lymphocyte ratio may correlate with the degree of inflammation and the area of the affected region. The eosinophil relative count and neutrophil-to-lymphocyte ratio may thus be stand-alone parameters from each other in the assessment of the severity of atopic dermatitis.

Introduction: Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disease characterized by eczema and pruritus, and frequently impairs sleep quality. Although cyclosporine improves symptoms of AD, objective evaluation of sleep in patients with AD treated with cyclosporine has not been reported. This study was conducted to elucidate the effects of cyclosporine on sleep quality for patients with AD. Methods: Twelve patients with moderate-tosevere AD were recruited. Nocturnal sleep quality was evaluated for 7 days using a sleep analyzer, which patients wore at the waist before and after cyclosporine was administered at 2.0-4.0 mg/kg per day. Seven parameters of sleep quality were measured before and after cyclosporine administration for a period of 7 days for each patient. Results: The administration of cyclosporine significantly improved total sleep time in four cases, sleep latency in two cases, wake after sleep onset in six cases, number of awakenings in two cases, sleep efficiency in seven cases, number of awakenings for more than 8 min in three cases, and number of position changes recorded every 2 min in three cases. The mean values of sleep latency significantly decreased after cyclosporine administration (P = 0.023). The mean value of sleep efficiency significantly increased after the administration (P = 0.002). Conclusion: Cyclosporine improves sleep quality in patients with moderate-to-severe AD.

Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is an autosomal dominant disease characterized by neurofibromas with infiltration of mast cells. Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR) and basophil-to-lymphocyte ratio (BLR) are examined as markers for various diseases. However, these parameters have not yet been assessed for NF1. This study therefore examined these parameters in NF1 patients. We recruited 153 NF patients (78 males, 75 females) and 51 control patients (31 males, 20 females). Complete blood counts were performed, then NLR, LMR, PLR and BLR were calculated. Neutrophil count was significantly higher in male NF1 patients than in male controls. Lymphocyte count was significantly lower in NF1 patients than in controls for both sexes. Monocyte count was significantly higher in male NF1 patients than in male controls. Basophil count was significantly higher in male NF1 patients than in male controls. NLR, PLR and BLR were significantly higher in NF1 patients than in controls for both sexes. LMR was significantly lower in NF1 patients than in controls for both sexes. NF1 shows high NLR, PLR and BLR and low lymphocyte count and LMR.
