MedicalResearch.com: What is the background for this study?
Response: Eczema (also known as atopic dermatitis) has become increasingly common over recent decades, especially in industrialized countries, suggesting that environmental or lifestyle factors like diet could impact rates of disease. It is well established that sodium, consumed primarily in the form of salt, increases the risk of hypertension and heart disease through pro-inflammatory mechanisms. The role of sodium on other chronic inflammatory conditions like eczema has been less well-studied.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The background for this study are studies that show that OX40 is a pathway that is upregulated in patients with atopic dermatitis (or eczema). OX40 is involved in activation of immune molecules associated with allergy and atopy, and also with formation of memory immune cells that are required for disease recurrence. The hypothesis to the study was that giving an OX40 antagonist will not only ameliorate the disease but perhaps have a remittive effect in that the disease will not come back.
Indeed all drug doses were significantly effective at week 16, the primary endpoint compared to placebo and continued to improve towards week 36, the secondary endpoint. In addition, the responders to treatment maintained their responses for an additional 20 weeks, which is unusual, suggesting a potential for disease modification.
