Which of the following can be a systemic complication of UTIs in high-risk patients?

• A. Prostatitis
• B. Epididymitis
• C. Gram-negative bacteremia
• D. Pyelonephritis

Answer: (C)

Systemic infection happens when urinary pathogens break into the bloodstream, leading to bacteremia and the possibility of sepsis. In high-risk patients—elderly, catheter users, diabetics, immunocompromised—the organisms that most often do this are Gram-negative bacteria such as E. coli. Once they’re circulating, their endotoxins can trigger a widespread inflammatory response, causing fever, rapid heart rate, low blood pressure, and potential organ dysfunction. The other conditions are localized problems: prostatitis and epididymitis affect specific organs and don’t inherently imply bacteria in the blood, and while pyelonephritis is a kidney infection and can be severe, it is typically described as a localized upper urinary tract infection rather than a systemic complication. Thus, bacteremia caused by Gram-negative bacteria best represents a systemic complication of UTIs in high-risk individuals.
