All of the following are common cause of post splenectomy infections except: September 2009
Correct Answer: Klebsiella
Description: Ans. C: Klebsiella The first description of overwhelming post-splenectomy infection was published by King and Schumaker in 1952. The disease may begin as a minor flu-like illness that rapidly escalates into a fulminant infection. It is most common in the first two years after splenectomy but may occur decades later. Splenectomy may be followed by severe systemic infection because such surgery removes the splenic macrophages that filter and phagocytose bacteria and other bloodborne pathogens. Overwhelming post-splenectomy infection (OPSI) is uncommon but has high moality. Overwhelming post-splenectomy infection is usually caused by the encapsulated bacteria Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis and more than half of those infected die. Other pathogens in such infection may include bacteria such as Escherichia coli and Pseudomonas aeruginosa, Capnocytophagia canimorsus, group B streptococci, Enterococcus spp, Ehrlichia spp, and protozoa such as the Plasmodium spp. leading to malaria.
