Outcomes of gram-positive peritonitis and gram-negative
peritonitis

In order to determine differences in prognosis of peritonitis
based on causative organism, the outcomes of Gram-positive
peritonitis (GPP) and Gram-negative peritonitis (GNP) in 375
patients were retrospectively compared. There were 250 episodes
of GPP and 57 episodes of GNP. Of the episodes of GPP, 17%
required hospital admission, 5% required catheter removal and 27%
were followed by a recurrent episode of peritonitis within 6 mo.
For GNP, the respective percentages were 74%, 18%, and 9%. Thus
although the morbidity of GNP is greater, recurrent peritonitis
is more likely with GPP.
Comment: It is not clear what the authors mean by
"recurrent"
peritonitis. Does this mean relapsing peritonitis (i.e.,
infection with the same organism after cessation of therapy)?
The latter generally is due to catheter infection, and is much
more common with Gram-positive organisms.
