“…These include low-energy, vegan, and vegetarian diets, as well as weight loss programs incorporating modified dietary strategies. Additionally, gluten-free, Mediterranean, and very-low-calorie diets devoid of carbohydrates have shown promise in supporting individuals with psoriasis [15]. Furthermore, the results of the meta-analysis studies demonstrated a significant association between obesity and vitamin D levels, with an increased prevalence of vitamin D deficiency among obese and overweight populations (defined by BMI index) in comparison to lean subjects, irrespective of age or ethnicity [16].…”

Background and Objectives: Psoriasis is a common, chronic, and immune-mediated inflammatory skin disease recognized to lead to a wide range of comorbid disorders, mainly obesity. The study aimed to evaluate the problem of overweightness and obesity among psoriasis patients in the context of their prevalence and influence on the disease course. Materials and Methods: The study group encompassed 147 adult patients with plaque psoriasis. Results: The prevalences of overweightness (39.46%) and obesity (37.41%) demonstrated in the study showed the strong predisposition of psoriatic patients for abnormal body mass. The vast majority (77%) of subjects with psoriatic arthritis were overweight or obese. The results of the correlation analysis revealed the significant impacts of overweightness and obesity, as defined by the BMI index, on modifying the severity of psoriasis (as assessed by the PASI with a correlation coefficient of R = 0.23, p = 0.016; and BSA values with a correlation coefficient of R = 0.21, p = 0.023), particularly in contrast to patients with a normal body mass. Conclusions: Overweightness and obesity constitute a major health burden among psoriatic patients, influencing the disease course and severity. Enhanced understanding of the phenomenon may directly translate into improving disease management and overall patient care.

Human skin is colonized with skin microbiota that includes commensal bacteria, fungi, arthropods, archaea and viruses. The composition of the microbiota varies at different anatomical locations according to changes in body temperature, pH, humidity/hydration or sebum content. A homeostatic skin microbiota is crucial to maintain epithelial barrier functions, to protect from invading pathogens and to interact with the immune system. Therefore, maintaining homeostasis holds promise to be an achievable goal for microbiome‐directed treatment strategies as well as a prophylactic strategy to prevent the development of skin diseases, as dysbiosis or disruption of homeostatic skin microbiota is associated with skin inflammation. A healthy skin microbiome is likely modulated by genetic as well as environmental and lifestyle factors. In this review, we aim to provide a complete overview of the lifestyle and environmental factors that can contribute to maintaining the skin microbiome healthy. Awareness of these factors could be the basis for a prophylactic strategy to prevent the development of skin diseases or to be used as a therapeutic approach.

Psoriasis is a chronic inflammatory skin disease with complex pathogenesis and variable severity. Performed studies have indicated the impact of vitamin D3 deficiency on the pathogenesis of psoriasis and its severity. However, there is no clear evidence of the influence of the mucosal microbiome on the onset and progression of psoriasis. This review aims to present the current evidence on the role of vitamin D3 and colonization of the oral mucosa by Candida yeast-like fungi in the pathogenesis of psoriasis. Candida albicans is a common yeast that can colonize the skin and mucosal surfaces, particularly in individuals with weakened immune systems or compromised skin barriers. In psoriasis, the skin’s barrier function is disrupted, potentially making patients more susceptible to fungal infections such as Candida. Since patients with psoriasis are at increased risk of metabolic syndrome, they may experience the vicious circle effect in which chronic inflammation leads to obesity. Vitamin D3 deficiency is also associated with microbiological imbalance, which may promote excessive growth of Candida fungi. Under normal conditions, the intestinal and oral microflora support the immune system. Vitamin D3 deficiency, however, leads to disruption of this balance, which allows Candida to overgrow and develop infections.
