Psoriatic disease, encompassing psoriasis (PsO) and psoriatic arthritis (PsA) is a chronic inflammatory condition influenced by genetic, immune, and environmental factors, particularly diet and gut microbiota. While biologics and DMARDs have improved disease management, treatment responses vary, and long-term remission remains difficult. Continuous inflammation control often requires pharmacological treatment, highlighting the need for adjunctive therapies.
Emerging research links gut microbiota imbalances (dysbiosis) to chronic inflammation, suggesting that dietary interventions could offer therapeutic benefits. Fasting and plant-based diets (PBD) may help regulate immune responses and gut microbiota composition. Fasting has been shown to reduce oxidative stress, promote autophagy, and alter immune cell dynamics, while PBD is associated with anti-inflammatory effects and enhanced microbial diversity.
The RiseFast Pilot Study aims to investigate whether a seven-day fasting period followed by a structured PBD can improve disease activity, quality of life, and gut microbiota in PsO and PsA patients. While prior studies suggest potential benefits, their specific effects on psoriatic disease remain unclear. By integrating clinical, microbiome, and immune profiling, the study aims to clarify dietary impacts on inflammation.
