Background: Multiple factors contribute to the pathogenesis of childhood vitiligo. The characteristics in a different population under modified environmental factors need further reevaluation. The present study aimed to reevaluate the clinical and laboratory features in consequent children vitiligo patients.
Materials And Methods: We retrospectively reviewed consequent children vitiligo patients who visited Children's Hospital of Fudan University (National Children's Medical Center of China). The prevalence rate of thyroid dysfunction, circulating autoantibodies, serum IgE, and associated factors were analyzed.
Results: A total of 244 consequent vitiligo patients were included, of which 20 children had personal autoimmune history. Two hundred and nineteen of the 244 patients took a thyroid function test, and the abnormal rate was only 3.7% (8/219). The elevated IgE rate was 31.7% (52/157), the antinuclear antibody (ANA) positive rate was 9.8% (12/123), and the extractable nuclear antigens (ENA) positive rate was 4.4% (4/91), respectively. The elevated IgE was significantly associated with atopic disease history and male gender. Of note, personal autoimmune history showed a significant inverse association with elevated IgE.
Conclusions: Thyroid dysfunction rate was low among the consequent children vitiligo patients. Personal autoimmune history was inversely associated with elevated IgE. Various clinical characteristics and pathogenesis might contribute to different long-term outcomes of vitiligo.

Objective: Prolidase deficiency is a metabolic and immunological disorder that is inherited in an autosomal recessive manner. In prolidase deficiency, a broad spectrum of differences is observed in patients, ranging from asymptomatic to multisystem involvement. There is scarce information in the literature on the atypical features and immunophenotypes of this disease.

Cow's milk allergy (CMA) is the most common food allergy among children. An oral food challenge (OFC) remains a mainstay of the diagnosis of CMA, especially for the non-IgE-mediated type; however, this test can be risky and time-consuming. Hence, there is a need to identify biomarkers.

This study aimed to investigate the factors influencing the complication of allergic rhinitis in children with bronchial asthma and to construct a nomogram model to predict the occurrence of allergic rhinitis. A total of 190 children with bronchial asthma admitted to our hospital from August 2020 to August 2024 were retrospectively analyzed. The children were randomly divided into the training cohort (133 cases) and validation cohort (57 cases) in a ratio of 7:3.

Background And Aims: Elevated total IgE levels are traditionally associated with allergic conditions; however, their potential role as biomarker for mortality risk beyond allergic diseases has not been extensively explored. Recent studies have suggested that IgE is associated with cardiovascular (CV) disease. We aimed to investigate the association between total IgE levels and the risk of all-cause and cause-specific mortality, as well as to explore the potential mediating role of vitamin status in these associations.

Objective: Retroperitoneal fibrosis (RPF) is a rare condition marked by inflammation and fibrosis affecting the peritoneal and retroperitoneal soft tissues. In recent years, the identification of IgG4-related diseases has brought to light a significant association with fibrous disorders, including RPF, which were once considered independent. In this comprehensive cohort study, we performed a comparative analysis of the demographic, clinical, laboratory, histopathological, and therapeutic characteristics between patients with IgG4-related RPF and those with idiopathic retroperitoneal fibrosis (iRPF).
