Final answer:
HIV infected patients are at greatest risk for Stevens-Johnson Syndrome compared to the other options listed. SJS is a severe reaction, often to medications or infections, and those with compromised immune systems, like individuals with HIV, face a higher risk.
Step-by-step explanation:
Among the options listed, c. HIV infected patients are at greatest risk for Stevens-Johnson Syndrome (SJS). SJS is a rare, serious disorder of the skin and mucous membranes, and it is often a reaction to a medication or an infection. Individuals with compromised immune systems, such as those with HIV, are at higher risk for complications from infections or adverse drug reactions, potentially leading to SJS.
To clarify, while lupus is an autoimmune disease that can affect any part of the body including the heart, it is not specifically an autoimmune disease of the heart. That would be rheumatic fever, which can develop after an infection and can lead to a condition known as rheumatic heart disease. However, this information is tangential to the main question regarding SJS risk.
