[Allergic pollen-induced myocarditis]
Abstract:
The paper concerns two cases of allergic pollen myocarditis. The diagnosis was confirmed by an evident relationship of myocardial lesion to the period of pollen production by allergenic plants or parenteral injection of an allergen and with the respiratory manifestations of pollenosis. In addition to the clinical picture of myocarditis (heart pain, dyspnea, abnormal rhythm), there were also alterations in blood serum enzymes (AsG, ASL-O). Roentgenologically, there was an enlargement of the boundaries mainly on the part of the left ventricle. Flaccid pulsation, ECG abnormalities of the rhythm, conduction and repolarization common to myocarditis were established. Both patients received therapy in an allergen-free ward and completely recovered. It is believed that specific immunotherapy is contraindicated in such patients. The treatment should be carried out in an allergological or cardiological hospital and should consist in the exclusion of allergenic food, administration of glucocorticosteroids, antihistaminic drugs, cardiac glycosides and potassium drugs until full disappearance of the clinical manifestations, normalization of the ECG and laboratory characteristics.
Insights
Allergic pollen myocarditis, a rare heart condition, can occur due to pollen exposure. Prompt diagnosis and allergen avoidance are key for recovery, with immunotherapy being contraindicated.
Area of Science:
- Cardiology
- Allergology
- Immunology
Background:
- Allergic reactions can manifest in various organs, including the heart.
- Pollen-induced allergic reactions, or pollenosis, are common respiratory conditions.
Observation:
- Two cases of allergic pollen myocarditis are presented.
- Diagnosis was confirmed by the temporal relationship between myocardial damage and pollen seasons or allergen exposure, alongside respiratory symptoms.
- Clinical signs included myocarditis symptoms (chest pain, dyspnea, arrhythmias), elevated serum enzymes (AST, ALT), left ventricular enlargement, and ECG abnormalities.
Findings:
- Allergic pollen myocarditis is linked to pollen exposure and pollenosis.
- Patients recovered fully after treatment in an allergen-free environment.
- Specific immunotherapy is contraindicated for this condition.
Implications:
- This study highlights allergic pollen myocarditis as a distinct clinical entity.
- Management requires allergen avoidance, anti-inflammatory, and supportive cardiac therapies.
- Care should be managed in specialized allergological or cardiology settings.
