Immune-mediated inflammatory diseases and nutrition: results from an online survey on patients' practices and perceptions

Anxiety and Work Disability in Patients With Immune-Mediated Inflammatory Diseases: A Cross-Sectional Study From a Single Center

Immune-mediated inflammatory diseases (IMIDs) are chronic diseases that are associated with an inflammatory process with unclear etiology and occur in genetically predisposed individuals. In this study, inflammatory bowel disease (IBD) and rheumatic disease (RD) were examined. The aim of the research is to evaluate the relationship between IMID and state anxiety and work impairment in patients. A cross-sectional study was conducted in an outpatient clinic for rheumatology and gastroenterology at an Italian university hospital. A total of 476 patients (261 IBD and 215 RD) were considered. Patients diagnosed with IBD demonstrated significantly higher levels of anxiety, encompassing both trait and state anxiety, compared to those with RD (p < .001). While trait anxiety exhibited a modest positive correlation with work productivity loss (r = .163; p = .046), activity impairment showed a positive correlation with both state anxiety (r = .243; p < .001) and trait anxiety (r = .206; p = .002). The impact of anxiety on job performance and daily activities should not be underestimated, as it may elevate the risk of unemployment and absenteeism and lead to increased societal costs.

Immune-Mediated Inflammatory Diseases Awareness and Management among Physicians Treating Patients with Inflammatory Bowel Disease: An IG-IBD Survey

(1) Background: Inflammatory bowel disease (IBD) is frequently associated to other immune-mediated inflammatory diseases (IMIDs). This study aims at assessing physicians' awareness of the issue and the current status of IMID management. (2) Methods: A web-based survey was distributed to all 567 physicians affiliated to IG-IBD. (3) Results: A total of 249 (43.9%) physicians completed the survey. Over 90% of the responding physicians were gastroenterology specialists, primarily working in public hospitals. About 51.0% of the physicians had access to an integrated outpatient clinic, where gastroenterologists collaborated with rheumatologists and 28.5% with dermatologists. However, for 36.5% of physicians, integrated ambulatory care was not feasible. Designated appointment slots for rheumatologists and dermatologists were accessible to 72.2% and 58.2% of physicians, respectively, while 20.1% had no access to designated slots. About 5.2% of physicians report investigating signs or symptoms of IMIDs only during the initial patient assessment. However, 87.9% inquired about the presence of concomitant IMIDs at the initial assessment and actively investigated any signs or symptoms during subsequent clinical examination. (4) Conclusions: While Italian physicians recognize the importance of IMIDs associated with IBD, organizational challenges impede the attainment of optimal multidisciplinary collaboration. Efforts should be directed toward enhancing practical frameworks to improve the overall management of these complex conditions.

The impact of dietary interventions in psoriatic arthritis

PURPOSE OF REVIEW

Psoriatic arthritis (PsA) is a common form of inflammatory arthritis that affects people with psoriasis. Both psoriasis and PsA are associated with metabolic diseases including obesity, hypertension, hyperlipidaemia, diabetes mellitus, fatty liver disease, and cardiovascular disease including myocardial infarction. Dietary interventions for psoriatic disease have been of great interest, particularly among patients with PsA.

RECENT FINDINGS

Herein, we review the evidence for dietary intervention in psoriatic arthritis. To date, weight loss among patients who are obese has the greatest evidence for benefit. We also examine the evidence for fasting, nutrient supplementation, and specific diets as adjunct therapeutic strategies.

SUMMARY

While the data do not clearly support a single dietary intervention across the disease, weight loss among those who are obese results in improved PsA disease activity and physical function. Additional studies are needed to better understand the impact of diet on psoriatic arthritis.

Beliefs, Experiences, and Openness Regarding Dietary Interventions: Data From an Urban Hispanic Population With Rheumatic Disease in the US

OBJECTIVE

To obtain descriptive data on the beliefs, behaviors, and openness regarding dietary changes for rheumatic diseases in an urban US Hispanic patient population with rheumatic disease as foundational data for future intervention design.

METHODS

We distributed a voluntary survey to our primarily Hispanic population at an outpatient rheumatology clinic for 19 weeks. This survey queried individuals' behaviors as they related to dietary intake used for the treatment of rheumatic disease, perceptions of the effect of food groups on rheumatic disease activity, barriers to physician-recommended diets, and willingness to try future interventions. We used descriptive statistics and Pearson's chi-square test to evaluate associations.

RESULTS

More than 40% of survey respondents from our primarily (88%) Hispanic population noted a link between what they ate and their underlying rheumatic disease activity. More than one-third of patients had, at some point, modified dietary intake to affect their rheumatic disease. Vegetables, fruit, and white meats were commonly reported to improve disease, while red meat and processed foods were reported to worsen disease. Barriers to following a prespecified diet included cost and lack of knowledge. More than 70% of respondents indicated willingness to attempt certain eating patterns should it help their underlying rheumatic disease.

CONCLUSION

In this primarily Hispanic rheumatic disease patient population, many have not only noted a correlation between dietary intake and rheumatic disease activity but are also open to future nutrition-related interventions. As this population experiences poor rheumatic disease outcomes and a high rate of lifestyle-related comorbidities, an intervention to optimize healthy eating patterns would likely be beneficial as well as acceptable.

Orthorexia Nervosa Practices in Rheumatoid Arthritis: The DORA Study

Medical nutrition therapy (MNT) is an indisputable component of the multidisciplinary therapeutic approach in rheumatoid arthritis (RA). Previous research has suggested that in chronic disease where nutrition is an important effector of prognosis, healthy dietary choices might take an unhealthy turn, with patients developing disordered eating in the form of orthorexia nervosa (ON). ON is characterized by a pathological preoccupation with "healthy", "pure" eating, associated with restrictive dietary patterns, nutrient deficiencies and worsening disease outcomes. The aim of the present cross-sectional study was to evaluate ON tendencies in a sample of adult patients with RA. A total of 133 patients with RA were recruited, and completed the ORTO-15 questionnaire for the assessment of ON tendencies. Most of the patients were overweight/obese (53.4%). The results revealed ON tendencies in the sample, with the median ORTO-15 score reaching 36 (IQR: 33-39). Greater ON tendencies were associated with the female gender, and lowered ON tendencies with increasing age and body mass index. The present findings highlight the need for health professional awareness regarding the problem of ON in patients with RA and the importance of screening patients.

The Role of the Gut Microbiome in Psoriasis: From Pathogens to Pathology

OBJECTIVE

The objective of this article is to bring awareness to the emerging frontier of the correlation of the gut microbiome and its impact on psoriasis.

METHODS

A Google Scholar and PubMed literature search was conducted utilizing key words "gut microbiome," "psoriasis," "diet," and "inflammation," yielding several articles for review and classification.

RESULTS

Randomized, controlled trials have revealed that gut microbial imbalances contribute to inflammatory cytokines as well as to the progression and development of psoriasis. Perhaps more importantly, perturbations in the gut microbiome have been correlated to elevated plasma levels of claudin-3, zonulin, and intestinal fatty acid-binding protein, contributing to intestinal barrier dysfunction and permeability. This translocation results in systemic immune activation leading to phenotypic expression of psoriasis in genetically susceptible individuals.

LIMITATIONS

Numerous limitations were found during the research on this topic, including lack of standardization of diets, coverage of stool testing by insurance, and personalized interactions of microbes on the host. Further studies are needed with longer follow-up and increased number of patients.

CONCLUSION

A healthy diet positively impacts the gut microbiome, which can dampen inflammatory cytokines and lessen the severity of psoriasis. The use of probiotics can also influence this dynamic.
