“…Bacterial infections are the most common complication of corticosteroid use (3). However, long-term treatment induces a significant defect in cell-mediated immunity that results in infections with opportunistic pathogens, including Pneumocystis (4,5), mycobacteria (6) (including Mycobacterium tuberculosis septic shock (7)), Candida (8), Aspergillus (9), Cryptococcus (10), Legionella (11), Nocardia (12), and Strongyloides (13). Corticosteroids are associated with increased infection, even in previously immunocompetent hosts (14), and they increase the risk of infection of any baseline immunocompromised state (15,16).…”
