Fatal sepsis following intravesical bacillus Calmette-Guerin administration for bladder cancer

Intravesical administration of bacillus Calmette-Guerin has been shown to be highly effective treatment of superficial bladder cancer. Complications from bacillus Calmette-Guerin therapy are usually minor but serious and even fatal reactions can occur. Five recent cases illustrate the gravity of bacillus Calmette-Guerin sepsis. One man with severe debility and the organic brain syndrome died acutely with a fever of 40 C. Two men had frank sepsis that progressed to multiorgan failure and death. Sepsis progressed despite the use of isoniazid, rifampin and streptomycin. Two men who had equally progressive sepsis with intravesical bacillus Calmette-Guerin survived with the use of cycloserine for the first 72 hours of treatment. Triple antituberculous antibiotics, including cycloserine, may be lifesaving. Sepsis resulted from intravenous absorption through inflamed or disrupted urothelium. Bacillus Calmette-Guerin treatment should not be administered in the presence of severe cystitis or after grossly traumatic catheterization.
