AEMCA Practice Exam

Which of the following is NOT a common cause of pericarditis?

1. HIV

2. Diabetes Mellitus

3. Systemic lupus erythematosus

4. Kidney failure

The correct answer is: Diabetes Mellitus

Pericarditis is an inflammation of the pericardium, the protective sac surrounding the heart. It can be caused by a variety of factors, including infections, autoimmune diseases, and other health conditions. HIV, systemic lupus erythematosus, and kidney failure are all associated with increased risks of developing pericarditis. HIV can lead to opportunistic infections that may result in pericardial inflammation. Systemic lupus erythematosus is an autoimmune disease known to affect the heart and can lead to pericarditis due to autoimmune-mediated inflammation. In cases of kidney failure, the accumulation of waste products and electrolytic imbalances can contribute to the development of pericarditis, particularly in the context of uremia. Diabetes mellitus, while it is a significant health condition that can lead to various cardiovascular issues, is not commonly cited as a direct cause of pericarditis. The relationship between diabetes and pericarditis does not share the same direct inflammatory mechanisms or associations as the other conditions listed. Thus, diabetes mellitus is less frequently linked to the inflammatory processes that lead to pericarditis, making it the option that is not considered a common cause.
