In some cases, a drug can cause the immune system to mistakenly think the body's own red blood cells are dangerous, foreign substances. Antibodies then develop against the red blood cells. The antibodies attach to red blood cells and cause them to break down too early. It is known that more than 150 drugs can cause this type of hemolytic anemia ...
Bacteremia can travel through the blood stream to distant sites in the body and cause infection (hematogenous spread). Hematogenous spread of bacteria is part of the pathophysiology of certain infections of the heart ( endocarditis ), structures around the brain ( meningitis ), and tuberculosis of the spine ( Pott's disease ).
The onset of symptoms can occasionally be gradual rather than sudden. [8] The cause of pericarditis often remains unknown but is believed to be most often due to a viral infection.
