Overview
Chronic infective pericarditis is a persistent condition characterized by recurrent pericardial inflammation of unknown etiology, often potentially linked to viral infections and autoimmune mechanisms 1.Diagnosis
Clinical presentation includes recurrent chest pain, pericardial friction rub, and possibly pericardial effusion
Diagnostic imaging: Echocardiography to assess pericardial effusion and cardiac function
Laboratory tests: Elevated inflammatory markers, presence of antimyocardial antibodies
Pericardiocentesis: Fluid analysis for culture, cytology, and viral markers 1Management
First-line treatments: Corticosteroids for immunosuppression; specific dosing not detailed beyond discontinuation in cases 1
Adjunctive therapies: Intravenous immunoglobulin (IVIG) at 0.4 g/kg daily for 5 consecutive days, repeated monthly initially then every 2 months, shown to help in some refractory cases 1Special Populations
No specific data provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1Key Recommendations
Consider high-dose intravenous immunoglobulin (IVIG) as an adjunctive therapy in patients with chronic idiopathic pericarditis who are refractory to conventional immunosuppressive treatments (Evidence: Weak) 1
Monitor response closely with clinical follow-up and imaging to assess efficacy and manage recurrence (Evidence: Expert opinion) 1
Evaluate for and manage underlying autoimmune markers, such as antimyocardial antibodies, alongside immunosuppressive therapy (Evidence: Moderate) 1References
