In short
This article discusses clinical trials investigating the use of Arrhenatherum Elatius, a grass pollen extract, as part of a mixture for treating allergic rhinitis and rhinoconjunctivitis caused by house dust mite allergies. The trials aim to assess the effectiveness and safety of subcutaneous immunotherapy using this grass pollen mixture in adults with moderate to severe symptoms.

What is ARRHENATHERUM ELATIUS?
ARRHENATHERUM ELATIUS is a type of grass pollen that is used in allergy testing and treatment. It is one of several grass pollens included in a mixture used for diagnosing and treating grass pollen allergies. This grass is also known as tall oatgrass or false oat-grass.
Medical Use
ARRHENATHERUM ELATIUS is primarily used in the context of allergy diagnosis and treatment. It is part of a solution used for skin-prick tests, which help doctors identify specific allergens that cause allergic reactions in patients. The product containing this grass pollen is called "HAL Allergy Prick Test Gräserpollen-Mischung," which is a mixture of various grass pollens used for diagnostic purposes.
Clinical Trial Information
While the provided clinical trial information doesn't specifically focus on ARRHENATHERUM ELATIUS alone, it does involve a treatment for grass pollen allergies, which likely includes this particular grass species. The trial is studying a treatment called PURETHAL Mites Mixture, which is used for subcutaneous immunotherapy (SCIT) in adults with moderate to severe allergic rhinitis or rhinoconjunctivitis caused by house dust mite allergy.
This study aims to assess the effectiveness of the treatment in reducing allergy symptoms and improving quality of life for patients. While it's not directly about ARRHENATHERUM ELATIUS, the trial provides insight into how similar allergen-based treatments are evaluated.
Administration
In the context of allergy testing, ARRHENATHERUM ELATIUS is administered as part of a skin-prick test. This involves placing a small drop of the allergen solution on the skin, usually on the forearm or back, and then lightly pricking the skin through the drop. The maximum dose for the skin-prick test is typically 1 drop, applied cutaneously (on the skin).
Potential Benefits
The primary benefit of using ARRHENATHERUM ELATIUS in allergy testing is to accurately diagnose grass pollen allergies. By identifying specific allergens, doctors can develop more targeted treatment plans for patients suffering from allergic rhinitis or rhinoconjunctivitis (inflammation of the nose and eyes due to allergies).
Safety and Side Effects
As ARRHENATHERUM ELATIUS is used in a diagnostic capacity, the risks associated with its use in skin-prick tests are generally low. However, as with any allergy test, there is a small risk of an allergic reaction. This is why these tests are always performed under medical supervision.
Who Can Use This Treatment?
The skin-prick test containing ARRHENATHERUM ELATIUS can be used on patients suspected of having grass pollen allergies. However, there are some conditions under which this test should not be performed:
- Patients with severe immune disorders or diseases requiring immunosuppressive medication
- Those with active malignancies or any malignant disease in the last 5 years
- Individuals with severe skin diseases that might affect the test results
- Pregnant or breastfeeding women (as a precautionary measure)
- People who have taken antihistamines or other medications that could interfere with the test results (these medications typically need to be stopped for a certain period before the test)
It's important to note that the decision to perform an allergy test should always be made by a healthcare professional based on the individual patient's medical history and current health status.
