Comparison of personality traits among patients with psoriasis, atopic dermatitis, and stress: a pilot study

Background: Psoriasis and atopic dermatitis are chronic skin diseases that greatly affect the quality of life. Both diseases can be triggered or exacerbated by stress. Objective: We aimed to differentiate personality traits between patients with chronic skin conditions and people treated for stress in a pilot study. Methods: Patients participating voluntarily in educational programs in Belgium and Switzerland were recruited to complete personality trait questionnaires, including the Temperament and Character Inventory (TCI) and the Tridimensional Personality Questionnaire (TPQ). A comparison was made with patients treated for work-related stress. Results: A total of 48 and 91 patients suffering from skin diseases and work-related stress, respectively, were included in the study. Based on the questionnaires, we found that dermatology patients were less persistent and impulsive than those with work-related stress. Dermatology patients also exhibited more rigidness and less focus on performance. Finally, patients with work-related stress seem more likely to change in response to health-promoting programs than patients with chronic dermatoses. Conclusion: Patients with chronic skin diseases may perceive and cope with stress differently in comparison to patients with work-related stress due to inherent personality traits. Therefore, stress coping mechanisms may differ among different diseases. More research is needed into the design of educational interventions and the impact of personality traits in disease-specific groups

The effects of Modified Intermittent Fasting in Psoriasis (MANGO) trial : a two-arm pilot randomized controlled open cross-over study

Background: Psoriasis is a complex disease associated with multiple comorbidities, including metabolic syndrome and leaky gut syndrome. Dietary lifestyle interventions have been reported to affect the disease in terms of lesional severity. It remains unclear how diets affect these comorbidities and the general health in psoriasis patients. Modified Intermittent Fasting (MIF) on 2 non-consecutive days has shown beneficial effects on metabolic parameters. A significant advantage of MIF over the currently investigated dietary changes is its feasibility. Objective: Here, we aim to study the effects of MIF on skin, gut and metabolic health in psoriasis patients. Methods: A two-arm pilot prospective cross-over randomized control trial (RCT) will be performed in 20 patients with psoriasis as a pilot study. Patients will be randomized 1:1 to either start with MIF and subsequent regular diet for 12 weeks each or to start with regular diet and subsequent MIF for 12 weeks each. The following parameters will be assessed: demographics, disease phenotype, medical and familial history, psoriasis severity, dermatology-specific and general quality of life, nutritional and physical habits, mental and intestinal health, intestinal and cutaneous integrity, inflammatory and metabolic markers, and satisfaction. Results: The aim is to uncover the effects of MIF on psoriasis severity and gut health integrity through clinical and molecular investigation. More precisely, we want to map the evolution of the different markers in response to MIF as compared to the regular diet, such as psoriasis severity, permeability and inflammation. Conclusions: Understanding how dietary lifestyles can affect epithelial lineages such as the skin and gut, will greatly improve our understanding on the development of psoriasis and may pose a non-pharmacological venue for treatments.

Gut-skin axis : current knowledge of the interrelationship between microbial dysbiosis and skin conditions

The microbiome plays an important role in a wide variety of skin disorders. Not only is the skin microbiome altered, but also surprisingly many skin diseases are accompanied by an altered gut microbiome. The microbiome is a key regulator for the immune system, as it aims to maintain homeostasis by communicating with tissues and organs in a bidirectional manner. Hence, dysbiosis in the skin and/or gut microbiome is associated with an altered immune response, promoting the development of skin diseases, such as atopic dermatitis, psoriasis, acne vulgaris, dandruff, and even skin cancer. Here, we focus on the associations between the microbiome, diet, metabolites, and immune responses in skin pathologies. This review describes an exhaustive list of common skin conditions with associated dysbiosis in the skin microbiome as well as the current body of evidence on gut microbiome dysbiosis, dietary links, and their interplay with skin conditions. An enhanced understanding of the local skin and gut microbiome including the underlying mechanisms is necessary to shed light on the microbial involvement in human skin diseases and to develop new therapeutic approaches

Improving patient involvement in the lifecycle of medicines : insights from the EUPATI BE survey

EUPATI Belgium (EUPATI.be) is an informal gathering of local partners who are interested in improving patient involvement in healthcare innovation and medicines research and development. EUPATI.be brings together various stakeholders from different areas related to healthcare including patients, academia and industry. In doing so, we create an innovative collaborative approach where actors from different backgrounds work toward improving patient involvement in medical research, and putting the patient at the center of the Belgian healthcare system. Previously, we performed in-depth interviews with a small group of stakeholders on patient involvement. Here, we elaborate on our previous findings by using a nation-wide survey to inquire into Belgian stakeholders' perception on patient involvement. To this end, an electronic survey was available in French, Dutch and English, and accessible for 11 months. Twelve questions were asked, including 11 multiple choice questions and 1 open question. The latter was thematically analyzed according to the framework method. A total of 117 responses were registered and descriptive statistics were performed. The majority of respondents could be categorized into patient, academia and industry, whereas policy makers, payers, and healthcare professionals were underrepresented. We identified several barriers that hamper patient involvement, which were sometimes more reported by specific stakeholder groups. Next, we found that various stakeholders still consider patient involvement as a passive role, i.e., medical subject in a clinical trial. Respondents also reported that the role of the various stakeholders needed more clarification; this was also confirmed by the level of trust amongst the various stakeholders. Existing and the wish for more collaboration with the various stakeholders was reported by almost all respondents. Based on this survey, we can define the potential of involving patients in the medical research and development in the Belgian landscape. Our results will help to understand and tackle the various barriers that currently hamper patient involvement, whilst highlighting the need for a collaborative landscape from the multi-stakeholder perspective

The implementation of a structured specialized consultation for psoriasis management

Objectives: Psoriasis is a chronic skin disease requiring a multidimensional approach, given its varying appearance, presence of comorbidities and complex treatment regimens. Psoriasis care is however often performed fragmented and, in case of flares, reactive with little integrated information on and for the patient. Literature suggests a multileveled approach of psoriasis, but the effects of its implementation have not yet been validated. The aim of this study is to analyze the impact of a multileveled psoriasis consultation format, named PsoPlus, which has been implemented since 2012 in the Department of Dermatology at Ghent University Hospital in Belgium. Methods: The patient population was divided into two groups: one following the regular consultation and one following the PsoPlus format. Demographic data, clinical outcome and treatment approach of psoriasis patients were compared. Results: Patients who opted for the specialized PsoPlus consultation were younger and had longer disease duration. Decision parameters such as disease severity and quality of life were reported more often in the PsoPlus group. In the latter, a higher rate of patients were started on systemic therapy compared to the regular consultation group, and reporting on adverse events was done more frequently. Conclusion: The implementation of a specialized consultation with comprehensive guidance facilitates documentation on disease-relevant parameters such as disease severity and quality of life. This format can be seen as a guidance for capturing data in a structured manner, with evidence showing that it significantly impacts treatment decision, treating not only psoriasis but the patient as a whole

Validation of a Patient Global Assessment for extent, severity and impact to define the severity strata for the Self Assessment Vitiligo Extent Score (SA-VES)

Background: The Self Assessment Vitiligo Extent Score (SA‐VES) is a validated, patient‐reported outcome measure to assess the body surface area affected with vitiligo. Information on how to translate the obtained score into extent, severity and impact strata (mild–moderate–severe) is still lacking. Stratification is helpful to define inclusion criteria for trials, enables comparison and pooling of trial results and can be used for epidemiological research. Objectives: The aim was to develop extent, severity and impact strata for the SA‐VES based on validated anchor‐based questions. Methods: In total, 315 patients with vitiligo (non‐segmental; age ≥ 16) recruited at the Ghent University Hospital (Belgium) completed a questionnaire that was conducted in cooperation with the Dutch Society for vitiligo patients to ensure content validity. First three anchor questions included in the questionnaire [Patient Global Assessment (PtGA) for vitiligo extent, severity and impact] were assessed for content validity, construct validity and intrarater reliability. Subsequently, the PtGAs were used to stratify the SA‐VES based on ROC analysis. Results: For all PtGAs (PtGA extent, PtGA severity, PtGA impact), at least 75% of hypotheses evaluated for construct validity were confirmed. Intrarater reliability of all PtGAs was good to excellent (ICCs PtGA extent: 0.623; PtGA severity: 0.828; PtGA impact: 0.851). The optimal cut‐off values of the SA‐VES between the three global categories (mild/limited – moderate – severe/extensive) were 1.05% and 6.45% based on PtGA extent, 2.07% and 4.8% based on PtGA severity and 2% and 3.35% based on PtGA impact. Conclusion: This study provides the first guide for the interpretation of the numerical output obtained by the SA‐VES (vitiligo extent) and enables the translation into a global vitiligo grading for extent, severity and impact. As patients’ interpretation of vitiligo extent, severity and impact may vary amongst patients worldwide, future international studies will be required
