Abstract

OBJECTIVE:

To review our experience with typhlitis among children treated for acute leukemia.

MATERIAL AND METHODS:

The medical records of children with acute leukemia and typhlitis between 2006 and 2009 were reviewed for demographics and symptoms, and for microbiological and imaging findings.

RESULTS:

In the 75 children with acute leukemia--54 with acute lymphoblastic leukemia (ALL) and 21 with acute myeloid leukemia (AML)--there were 10 episodes of typhlitis (4.5%) that developed during 221 periods of severe neutropenia. The cumulative risk of typhlitis was 7.4% in patients with ALL and 28.5% in patients with AML. Frequent symptoms were: abdominal pain and tenderness (100% each); fever and nausea (90% each); emesis (80%); diarrhea (50%), and hypotension, peritonitis and abdominal distension (10% each). The median duration of symptoms was 6 days (range: 2-11 days), and that of neutropenia 14 days (range: 3-25 days). All patients were treated medically and none surgically. Two patients died because of typhlitis and sepsis.

CONCLUSIONS:

In our study, the rate of typhlitis among leukemic children was 4.5%; however, the mortality rate was 20%. Thus, rapid identification and timely, aggressive medical intervention are necessary to reduce the morbidity and mortality from typhlitis.
