B58.81

Clinical Causes: Infection with the Toxoplasma gondii parasite, which is commonly transmitted through undercooked contaminated meat, contaminated water, or exposure to infected cat feces. Acquisition of infection during pregnancy, which can lead to congenital toxoplasmosis in the fetus. Reactivation of latent infection in immunocompromised individuals, such as those with HIV/AIDS or undergoing immunosuppressive therapy.

Key Symptoms: Chest pain or discomfort Shortness of breath, especially with exertion Fatigue and weakness Palpitations or irregular heartbeat Swelling in the legs, ankles, or abdomen Fever and fatigue in some cases Possibly no symptoms in early stages or mild cases

Diagnosis Path: Diagnosis of toxoplasma myocarditis involves a combination of medical history, physical examination, and laboratory assessments. Tests may include blood analysis to detect antibodies against Toxoplasma gondii, imaging studies such as echocardiograms to evaluate heart function, and sometimes cardiac MRI. In certain cases, endomyocardial biopsy might be performed to directly identify the parasite or associated inflammation. Differential diagnosis is essential to distinguish this condition from other causes of myocarditis.

Treatment Protocols: Management typically involves antiparasitic medications such as pyrimethamine combined with sulfadiazine and folinic acid to eliminate the infection. Supportive treatments may include medications to manage heart failure symptoms, such as diuretics, ACE inhibitors, or beta-blockers. In severe cases, hospitalization might be necessary to monitor and support cardiac function. Prevention strategies include avoiding undercooked meat and practicing good hygiene, especially for pregnant women and immunocompromised individuals.
