“…Patients often ask for dietary interventions, because they are simple, cost-effective, and may benefit some patients with refractory CSU, but there are no precise tools to detect them. 8 Several promising biomarkers are under focus to predict the efficacy of dietary intervention for the treatment of CSU. 9 A study of 240 children with CSU has shown that food sensitization could predict inadequate treatment response.…”

Background: While the link between foods and chronic spontaneous urticaria (CSU) is controversial, many immunological mechanisms have been proposed to establish a causal relationship. Objective: To explore the potential benefit of avoiding immunoglobulin G (IgG)-mediated food hypersensitivity as a triggering factor in a case with CSU.History: The patient is a 50-year-old woman who complained of CSU for 1 and half year, which responded partially and temporarily to antihistamine medications. Of interest, it started 6 months after she followed an oat-rich diet. Her Urticaria Activity Score 7 was 23 out of 40. Results: Specific immunoglobulin E responses to common food and inhalant allergens were negative. A food-specific IgG antibody test was conducted, and it was mainly elevated for chicken eggs, rye, sweet pepper, gluten, garlic, wheat, and pineapple. Avoiding these foods had a curative effect on the CSU over a 2-month period. Conclusion: To the best of our knowledge, this is the first case report of symptoms of CSU that resolved after identifying and avoiding food items with IgG antibodies. Furthermore, well-controlled studies are advocated to verify the potential role of IgG food hypersensitivity in the pathogenesis of CSU.

“…While CSU patients often consider dietary modifications, the etiopathogenic role of food is uncertain, leading to controversy over dietary strategies. Elimination diets lack strong evidence, with food additives and personalized diets recommended cautiously [ 31 ]. Allergenic substances may be eliminated in proven food allergies.…”

“…The health of the gut microbiota is thought to influence skin health and the development of acne through its effects on the immune system and the level of inflammation it is programmed to create (Figure 8 ). Studies reveal associations between acne and dairy consumption, particularly with skim milk due to its growth hormones and steroids [ 31 ]. The Western diet, high in glycemic load foods such as sugar and refined grains, has been implicated in acne pathogenesis.…”

The role of diet in the development of skin disorders is well-established, with nutritional deficiency often identified as a risk factor for skin diseases. Imbalances in the skin can be caused by nutritional deficiencies, excessive intake, insufficient nutrients, and hazardous ingredients. Patients frequently inquire about the impact of dietary patterns on skin health when consulting dermatologists in clinical settings. Simultaneously, the popularity of using nutritional supplements containing vitamins, minerals, and nutraceutical blends has been on the rise. It is crucial for dermatologists, primary care physicians, and other healthcare providers to be acquainted with evidence-based dietary interventions, distinguishing them from those that are more market-driven than truly efficacious. This review explores the modification of diet, encompassing both dietary exclusion and supplementation, as a therapeutic approach for conditions such as psoriasis, atopic dermatitis, bullous disease, vitiligo, and alopecia areata. A comprehensive literature search, utilizing the PubMed/Medline, Google Scholar, and Medscape databases, was conducted to investigate the relationship between each nutrient and various inflammatory skin diseases. The findings emphasize the significance of a well-balanced and thoughtfully planned diet in supplying adequate amounts of proteins, vitamins, and minerals to support optimal skin health. Additionally, this comprehensive review navigates through various dietary recommendations, offering insights into their multifaceted impacts on the immune system, gut microbiome, and skin health. The goal is to pave the way for informed and targeted dietary interventions for individuals dealing with food allergies and associated skin conditions.

“…Since first-line CSU therapy (antihistamines) may not achieve satisfactory disease control for these patients, there is an unmet need for more effective therapy options, including possible dietary strategies and supplementation [ 80 ]. Probiotics are viable microorganisms with beneficial effects on the body and are generally safe when consumed in appropriate quantities [ 81 ].…”

Recent studies have linked gut microorganism composition and chronic urticaria (CU); however, the underlying mechanisms responsible for this connection are unknown. Since the human immune system is in homeostasis with microbiota, and the composition of the microbiome regulates the development and function of the immune system, it is likely that an alteration of microbiota components (a dysbiosis) could influence the course of chronic spontaneous urticaria (CSU), including disease severity, patient quality of life and treatment outcome. To date, several studies have identified changes in the gut microbiota composition of patients with CSU, though only a few have exhibited metabolic abnormalities associated with gut dysbiosis. The studies on CSU patients predominantly showed that the relative abundance of beneficial bacteria was decreased (Firmicutes and Bacteroides), while that of opportunistic bacteria was increased (Enterobacteria and Proteobacteria). In addition, serum metabolome analysis revealed that gut microbiota-associated alterations in unsaturated fatty acids and the butanoate metabolism pathway may play a role in CSU. These findings are potentially associated with inflammation mediated by the imbalance of Th1/Th2/Th17 cytokines, which might contribute to CSU pathogenesis. Further research in this field could improve clinical, diagnostic, and therapeutic approaches to patients with CSU. By applying new knowledge on gut microbial communities and metabolomics, future CSU therapies could modify the microbiota composition using agents such as probiotics or other similar agents, which, in combination with current standard therapies, could hopefully lead to a reduction in symptoms and an improved quality of life for CSU patients.
