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. AD patients were further divided by age and disease severity (mild, moderate-to-severe AD). We created a decision tree to predict moderate-severe AD. Results: A total of 13,928 patients with AD were included in this study: 6,828 adults and 7,100 children, with 13,548 controls. NLR, PLR, and ELR were lower in children compared to adults (p values <0.001). NLR, PLR, ELR, and ENR were increased in moderate-severe AD patients compared to mild AD patients (p values <0.001). PLR, ELR, and ENR were increased in AD patients versus controls (p values <0.001), with an additional increase in the NLR of moderate-to-severe AD patients. Patients with an ELR <0.21, a PLR >161, and ENR ≤0.016 should be considered high risk for developing severe AD, as well as patients with an ELR >0.21 and age at diagnosis <30 or age >30 years and mean platelet volume ≤9. Conclusion: Hematological ratios were significantly higher in moderate-to-severe AD patients, compared to mild AD patients. Hematological markers were lower in children with AD compared to adults, except for ENR, likely reflecting age-related changes in blood count parameters. These markers can assist in the management and follow-up of AD patients. [ABSTRACT FROM AUTHOR]

Background: Hematological markers such as eosinophil-to-lymphocyte (ELR), eosinophil-to-neutrophil (ENR), and eosinophil-to-monocyte (EMR) ratios may be used in the assessment of skin diseases. However, the relationship with vitiligo remains unclear. Objectives: We investigated ELR, ENR, and EMR in vitiligo patients and the association with severe vitiligo. Methods: This study included patients of all ages diagnosed with vitiligo between 2005–2020. ELR, EMR, and ENR were calculated from complete blood counts within 30 days of the first recorded vitiligo diagnosis and 12–18 months before the vitiligo diagnosis. We evaluated the associations between ELR, ENR, and EMR and vitiligo. Results: 9,826 vitiligo patients (8,398 adults and 1,428 children) and 8,951 age and sex-matched controls were included in this study. We found that ELR, EMR, and ENR were higher in children than in adults. Patients with vitiligo had higher ENR and EMR than their matched controls. Patients with severe vitiligo had higher ELR, ENR, and EMR compared to patients with mild vitiligo. Patients with increased ENR and EMR 12–18 months before the vitiligo diagnosis had a higher chance of having severe vitiligo (ENR: OR = 7.40, p<0.001, EMR: OR = 3.17, p<0.001). Conclusion: ELR, ENR, and EMR may be used in the assessment and prognosis of vitiligo, especially in severe cases. [ABSTRACT FROM AUTHOR]

Background: One‐third of psoriasis cases occur in the pediatric population. Pediatric psoriasis has a negative long‐term impact on the quality of life of children and their families. However, data regarding the impact of pediatric psoriasis on parental sleep quality are scarce. Objectives: This study examined the effects of pediatric psoriasis on the quality of parents' sleep compared to parents of healthy, non‐psoriatic children. Methods: A cross‐sectional questionnaire study was conducted from September 2020 to November 2021, using the validated Pittsburgh Sleep Quality Index (PSQI). The study population included parents of patients aged 2–18 years diagnosed with psoriasis and parents of healthy children of the same gender and ethnicity. We further compared sleep quality between parents of children with mild and moderate‐to‐severe psoriasis, and fathers to mothers. Results: A total of 301 parents were enrolled; 151 parents of 83 children diagnosed with psoriasis and 150 parents of 124 healthy controls. Parents of children with psoriasis had significantly longer sleep latency (p = 0.031), worse subjective sleep quality (p = 0.043), and greater use of sleep medications (p < 0.001). The comparison between parents of moderate–severe with mild psoriatic children as well as mothers with fathers showed no statistical significance. Conclusion: Poor sleep quality was demonstrated among parents of children diagnosed with psoriasis compared to parents of healthy children. This finding is crucial for the direction of treatment efforts regarding parental well‐being and functioning. [ABSTRACT FROM AUTHOR]

Chronic spontaneous urticaria (CSU) is a disturbing skin condition often severely detrimental to quality of life. Haematological markers of inflammation such as neutrophil-to-lymphocyte and platelet-to-lymphocyte may be used in the assessment of inflammatory skin diseases. Their usefulness in urticaria is unknown. Neutrophil- to-lymphocyte, platelet-to-lymphocyte, and total serum IgE were investigated in urticaria patients: acute spontaneous urticaria (ASU) versus CSU, children versus adults with CSU, and patients with mild-to-moderate versus severe CSU. This retrospective cohort study included patients of all ages diagnosed with urticaria between 2005 and 2020 and blood counts within 30 days of diagnosis. Patients with comorbidities influencing blood cells (infection, surgery, malignancy) were excluded. Neutrophil-to-lymphocyte and platelet-to-lymphocyte were evaluated in patients with ASU vs CSU and mild-to-moderate CSU vs severe CSU (defined by the use of systemic medications or hospitalizations). A total of 13,541 urticaria patients were included in the study. CSU patients (n = 5,021) had higher neutrophil-to-lymphocyte and platelet-to-lymphocyte, as well as serum IgE levels compared with ASU patients (n = 8,520). Adults had higher neutrophil-to-lymphocyte and platelet-to-lymphocyte than children. Severely affected patients (n = 53) had higher neutrophil-to-lymphocyte and platelet-to-lymphocyte compared with mild-to-moderately affected patients (n = 4,968). Patients with higher neutrophil-to-lymphocyte and platelet-to-lymphocyte had higher odds of having CSU rather than ASU and severe urticaria rather mild-to-moderate. In conclusion, neutrophil-to-lymphocyte and platelet-to-lymphocyte are simple and available markers that can be used to predict and assess severe and chronic urticaria.

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., Objectives: We aimed to investigate hematological ratios between children and adults, patients and controls, and patients with moderate-to-severe and mild psoriasis., Materials and Methods: This national retrospective cohort study included over 16,000 psoriasis patients in Israel. Patients with comorbidities influencing blood counts were excluded. Ratios were calculated from blood counts taken within 30 days of diagnosis. Multivariable logistic regression, including age, gender, ethnicity, smoking status, and socioeconomic status, was performed., Results: Findings revealed age-specific variations in blood counts, hematological ratios, and differences between mild and moderate-severe patients and patients versus controls. Moderate-severe psoriasis patients had elevated neutrophil and eosinophil counts (4.57 vs. 4.25, P < 0.001, and 0.24 vs. 0.22, P = 0.047, respectively), as well as increased NLR (2.46 vs. 2.29, P < 0.001). Multivariable logistic regression analysis confirmed the significance of neutrophil and platelet counts as well as NLR and PLR in predicting psoriasis severity., Limitations: This was a retrospective study without subjective data on disease severity., Conclusion: This study highlights hematologic ratios' diagnostic and prognostic potential in psoriasis., (© 2024 the International Society of Dermatology.)

Background: Colorectal cancer (CRC) is a feared complication of inflammatory bowel disease (IBD). We aimed to investigate the prevalence and risk factors of CRC among a large cohort of IBD patients., Methods: Data on IBD patients free of CRC at baseline was extracted using the MDClone platform of the Clalit health maintenance organization in Israel. We investigated the frequency rate of CRC among IBD patients compared to a control group without IBD. Possible risk factors, including comorbidities and IBD-related medications, were investigated in a multivariate analysis., Results: During a follow-up of 139,448 years among Crohn's disease (CD) patients and 139,533 years among ulcerative colitis (UC) patients, a frequency rate of CRC was 1.5% (191) among 12,888 CD patients and 2.1% (261) among 12,381 UC patients compared to 1.2% among 57,334 controls. In a multivariate analysis of UC patients, age at diagnosis (OR 1.030, p  < 0.001), primary sclerosing cholangitis (OR 2.487, p  = 0.005), diabetes mellitus (OR 2.01, p  < 0.001), and glucocorticoids treatment (OR 1.465, p  = 0.008) were found to be predictors of CRC. For CD patients, age at diagnosis (OR 1.035, p  < 0.001), primary sclerosing cholangitis (OR 2.25, p  = 0.029), and glucocorticoids treatment (OR 2.07, p  < 0.001) were found to be predictors for CRC, but not diabetes mellitus., Conclusion: Despite the continuously decreasing rates of CRC among IBD patients, these are still higher in IBD patients compared to the general population. IBD patients, particularly those with risk factors, require special consideration in follow-up for CRC., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Abu-Freha, Cohen, Gordon, Weissmann, Kestenbaum, Vosko, Abu-Tailakh, Ben-Shoshan, Cohen and Shirin.)
