ABSTRACT
Background. The frequency of bacterial infections (BI) in intestinal transplant (IT)
patients is high with sepsis being the leading cause of death after this procedure. We herein
report our experience with major BI to ascertain the incidence, microbiological and clinical
factors, risk factors and outcome.
Materials and methods. 124 patients (72 children and 52 adults) received 135 grafts:
namely, 39 isolated intestine, 33 liver–intestine and 63 multivisceral. Only major BI were
considered, namely, those associated with serious morbidity/mortality requiring specific
therapy. Patient data were retrieved from computerized databases, flow-charts, and
medical records.
Results. 92.7% patients showed BI. There were 327 episodes, representing 2.6 episodes/
patient (2.8/patients with infection): 193 episodes of bacteremia (1.7/patient with BI)
including 29.5% due to catheter related sepsis, 16.5% from abdominal source, 5.7% from
respiratory origin and 4.1% from the wound. The organ locations includes 46 respiratory
infections, 33 intraabdominal abscesses or infected fluid collections, 8 diffuse peritonitis, 34
wound infections and other miscellaneous sites: empyema, soft tissue infections, cholan-
gitis. . .etc. Median time of infection was nine days after surgery (mean 22 3 days), with
67.7% patients having at least one BI before the end of the first month. Infection was
present in 76.2% of the 63 deceased patients. An infectious episode during month 1, a
clinically manifest abdominal infection and a positive intraabdominal culture had negative
impacts on patient survival.
Conclusions. BI are common and early complications after IT. The high rate of
bacteremia, line sepsis and abdominal and respiratory infections reflect the recipient’s
condition, with chronic deterioration superimposed with the effects of prolonged abdom-
inal visceral surgery.
B
ACTERIAL infections (BI) are frequent among intes-
tinal transplant (IT) patients, and sepsis is the main
cause of death. IT recipients need prolonged abdominal
operations (usually with multiple anastomoses), heavy im-
munosuppression and frequent access to the bloodstream
for medication and nutrition. These conditions explain the
high incidence of bacterial infections. We reviewed the
major bacterial infections in intestinal transplantation (isolat-
ed and combined with other organs) at the University of
Miami/Jackson Memorial Hospital. We studied the incidence,
microbiological and clinical factors related to these infections.
MATERIALS AND METHODS
All the IT performed at our institution from 1994 to the end of
2001 were included namely, 124 patients who received 135 grafts:
39 were isolated intestine, 33 liver–intestine, and 63 multivisceral.
There were 72 children and 52 adults mean ages 3.41 0.46 years
and 35.79 1.42 year, respectively. Mean follow-up was 535.3
58.12 days.
Only major bacterial infections are considered namely, those
associated with serious morbidity and mortality that required
