Selective Mediterranean Diet in Immune Thrombocytopenia
The Effect of a Selective Mediterranean Diet Regimen on Platelet Count and Clinical Outcomes in Patients With Primary Immune Thrombocytopenia: A Randomized Controlled Trial

Description détaillée
Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by immune-mediated platelet destruction and impaired platelet production. Emerging evidence suggests that dietary patterns, particularly the Mediterranean diet, may influence immune regulation, systemic inflammation, and gut microbiota, which could affect the course of autoimmune diseases including ITP.
This randomized controlled trial will assess the effect of a selective Mediterranean diet-based regimen as an adjunct to standard pharmacological treatment on clinical and hematological outcomes in patients with primary ITP. Participants will continue their usual ITP medications throughout the study. The primary focus will be on changes in platelet count and bleeding severity over 12 weeks.

Intervention / Traitement |
|---|---|
|
Expérimental: Mediterranean Diet + Standard Therapy
Participants will follow a selective Mediterranean diet regimen in addition to their usual standard treatment for immune thrombocytopenia.
|
A selective Mediterranean diet regimen based on Mediterranean diet principles with stepwise elimination and reintroduction of certain foods, as an adjunct to standard pharmacological treatment for immune thrombocytopenia (ITP).
Standard pharmacological treatment for primary immune thrombocytopenia as prescribed by the treating physician, including corticosteroids (e.g., dexamethasone, prednisone) or intravenous immunoglobulin (IVIg), according to standard clinical guidelines.
|
|
Comparateur actif: Standard Therapy Only
Participants will continue their usual standard pharmacological treatment for immune thrombocytopenia without dietary intervention.
|
Standard pharmacological treatment for primary immune thrombocytopenia as prescribed by the treating physician, including corticosteroids (e.g., dexamethasone, prednisone) or intravenous immunoglobulin (IVIg), according to standard clinical guidelines.
