PG - e50812 LID - 10.7759/cureus.50812 [doi] LID - e50812 AB - Cow's milk protein allergies (CMPAs) particularly occur in infancy and early childhood due to an immunological allergic reaction to milk proteins. This issue is increasing in Saudi Arabia and requires research to improve health status and provide alternatives. Our study aims to investigate the important aspects of immunoglobulin E (IgE) and IgG CMPA in Saudi Arabia regarding its prevalence and association with demographic and health-related factors in both adult and pediatric populations. A descriptive retrospective cross-sectional study was conducted on 376 patients, comprising 314 adults aged between 19 and 86 years, and 62 pediatric patients aged between one and 12 years. The study focused on individuals who attended a private medical center in Jeddah city over the past five years. Laboratory results for food allergy of IgE and IgG tests, including cow's milk proteins (CMPs), serum 25-hydroxyvitamin D (25OHD), specific IgE inhalant allergy results, and other health-related factors were collected from an electronic record system. Results have shown that casein was the most common sensitizing allergen of CMPs in adults, whereas alpha-lactalbumin was the most common sensitizing allergen in pediatrics. The most frequent sensitizing allergen in IgG CMP was cow's milk in 54/92 (58.7%) adults, followed by cow's sour milk products 41 (44.6%). Cow's milk was the most common sensitizing allergen in 20/20 (100%) children. The rate of CMPA was significantly higher in children younger than five years old (P =0.003), while children who interacted with pets had a marginal significantly reduced rate (P = 0.054). Thus, cow's milk is the most sensitizing allergen in IgG CMPs in adults and pediatrics. CI - Copyright (c) 2023, Baghlaf et al.
