Scientists are investigating how eosinophilsEosinophils are a type of white blood cell primarily involved in fighting parasitic infections and allergic reactions. They are characterized by their ability to absorb eosin, a red dye. are formed and which genetic or environmental factors promote their overproduction. This research aims to identify the underlying genetic predispositions that could make certain dogs more susceptible to this disease.
Another area of research concerns the development of non-invasive diagnostic methods. Currently, the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of eosinophilic gastroenteritis is often associated with invasive procedures such as biopsies. Researchers are working to develop blood tests or other non-invasive methods that make it possible to detect the disease early and without major stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. for the animals.
Therapeutic approaches are also a focus of research. There are efforts to develop new drugs that specifically target the reduction of eosinophilic cell counts or otherwise modulate the body’s immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens.. These drugs could help alleviate the symptoms of the disease and improve the quality of life of affected dogs.
Furthermore, it is being investigated how dietary changes can contribute to the therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. of this disease. Some studies suggest that special diets that avoid certain proteins or contain hypoallergenic ingredients could help reduce the symptoms. These diets are often used as part of a more comprehensive therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life.
