Alternaria alternata 12X
Also known as: Alternaria alternata, Mold
Overview
Alternaria alternata is a common species of fungus found in soil, plants, and various organic materials. It is a well-known allergen, particularly through its Alt a 1 protein, and is primarily used in allergen-specific immunotherapy (ASIT) to treat mold allergies. Unlike typical dietary supplements, Alternaria alternata is utilized in a clinical setting to desensitize individuals to its allergenic effects. The immunotherapy involves administering gradually increasing doses of Alternaria alternata extracts to reduce the immune system's response over time. While research on its use in immunotherapy is ongoing, studies suggest potential benefits in alleviating respiratory symptoms and improving the quality of life for those with mold allergies. The quality of evidence varies, with some studies showing promising results but often limited by small sample sizes and methodological variations. It is administered via subcutaneous injections or other routes to induce immune tolerance.
Benefits
Allergen-specific immunotherapy (ASIT) with Alternaria alternata extracts has demonstrated significant improvements in respiratory symptoms and overall quality of life for individuals suffering from mold allergies. Studies indicate that immunotherapy can effectively reduce symptoms and decrease the need for medication by desensitizing patients to the Alt a 1 allergen. Furthermore, there is evidence suggesting improvements in peak expiratory flow (PEF) and a reduction in the severity of asthma and rhinitis symptoms. These benefits are primarily observed in individuals diagnosed with allergies to Alternaria alternata, particularly those experiencing rhinitis and asthma. Clinical improvements are typically noticeable after several months of consistent treatment, highlighting the potential for long-term relief from mold-related allergic reactions.
How it works
Immunotherapy with Alternaria alternata works by gradually increasing a patient's tolerance to the allergen, thereby reducing the immune system's hypersensitive response over time. This process primarily interacts with the immune system, specifically targeting IgE-mediated responses that cause allergic reactions. The main molecular target is the Alt a 1 allergen, a major allergenic protein of Alternaria alternata. By repeatedly exposing the body to small, controlled doses of the allergen, the immune system becomes less reactive, leading to a decrease in allergic symptoms. This desensitization process helps to re-educate the immune system, shifting its response from an allergic one to a more tolerant state.
Side effects
Allergen-specific immunotherapy (ASIT) with Alternaria alternata extracts is generally considered safe, with most adverse reactions being mild and localized. Common side effects include mild local reactions at the injection site, such as redness, swelling, or itching. Uncommon side effects may involve systemic reactions, though these are rare. Severe systemic reactions, including anaphylaxis, are very rare but require immediate medical attention. Contraindications for ASIT include severe uncontrolled asthma and certain autoimmune conditions. Caution is advised when considering ASIT for pediatric populations and during pregnancy. While drug interactions specific to Alternaria alternata extracts are not well-documented, it is essential to inform healthcare providers of all medications being taken. Patients should be closely monitored during and after treatment to ensure prompt management of any adverse reactions.
Dosage
The dosing of Alternaria alternata in allergen-specific immunotherapy (ASIT) typically follows a conventional immunotherapy schedule. Treatment begins with low doses, which are gradually increased to a maintenance dose over time. Specific optimal dosage ranges are not well-defined and may vary based on individual patient responses and tolerance. The maximum safe dose is generally determined by the absence of severe adverse reactions. Treatment is usually administered over several months to a year to achieve optimal results. Subcutaneous injections are the most common form of administration. As this is immunotherapy, absorption factors and required cofactors are not applicable in the same way as with dietary supplements. Patients should be closely monitored by healthcare professionals throughout the treatment process.
FAQs
How is Alternaria alternata used?
It is used in allergen-specific immunotherapy (ASIT) to treat mold allergies by gradually increasing tolerance to the allergen.
Is ASIT with Alternaria alternata safe?

Improvements in allergy symptoms are typically observed after several months of consistent treatment.
Who should administer the treatment?
Treatment should be administered by a healthcare professional trained in allergy management and immunotherapy.
Is Alternaria alternata a dietary supplement?
No, it is not a dietary supplement but a form of immunotherapy used to treat mold allergies.
