Intranuclear inclusion bodies were found by light microscopy in epithelial cells in more than one-third of the specimens from children operated on for ileocecal
intussusception
. Electron microscopic examination done on hematoxylin and eosin-stained slides showed the intranuclear inclusion bodies to be composed of viral particles in large and small crystalline arrays.
Adenovirus
of serotypes 2, 3, and 5 were isolated from the five cases with inclusions in which isolation was attempted. These findings strongly suggest a pathogenetic role for adenovirus in those cases of
intussusception
in which intranuclear inclusion bodies are found in the epithelial cells of the appendix or the terminal ileum.

The vermiform appendix may react as part of a generalized viral infection, but histological documentation of appendiceal viral infection is rare.
Adenovirus
has been described in association with mesenteric adenitis and ileocecal
intussusception
, but to our knowledge there are no well-documented cases of adenoviral appendiceal infection presenting clinically as acute appendicitis without
intussusception
. We reviewed the pathology records of all appendectomies performed at our institution from 2001 through 2005. All incidental appendectomies and appendices with acute appendicitis or other pathological findings were excluded. We selected all negative appendices with lymphoid hyperplasia and reviewed hematoxylin and eosin-stained slides. Representative sections of each of these cases were immunostained with adenovirus antibody. Eight hundred seventy-seven appendectomies were performed during the study period. Of these, there were 94 cases that had a clinical diagnosis of acute appendicitis and that were pathologically negative. Sixty-three of the 94 cases had lymphoid hyperplasia and were stained for adenovirus. We identified 2 positive cases, which also showed epithelial proliferation and viral inclusions. One involved a 6-year-old male and the other involved a 5-year-old female, without
intussusception
.
Adenovirus
can infect the appendix and clinically mimic acute appendicitis without
intussusception
. We recommend that all negative appendices be evaluated for lymphoid hyperplasia and epithelial viral changes and possibly be stained with immunoperoxidase staining if indicated. We speculate that adenovirus may play a role in the pathogenesis of acute appendicitis.

We investigated the adenoviral etiology and seasonal epidemic trends in
intussusception
and each adenoviral subgroup. Also we confirmed whether we can use the adenovirus data of Acute Infectious Agents Laboratory Surveillance Report (AIALSR) as an epidemic predictor of
intussusception
. Patients with
intussusception
(n = 126), < 5 years old, were enrolled and matched by age and sex with controls suffering acute gastroenteritis without
intussusception
(n = 106), all recruited at 8 centers. All fecal specimens were assayed for adenovirus, including subgroups A, B, C, E, and F, with reverse transcriptase-polymerase chain reaction (RT-PCR).
Adenovirus
was detected in 53 cases and 13 controls (P < 0.001). Nonenteric adenoviruses (NEAds) were detected in 51 cases and four controls (P < 0.001). We used Spearman's correlation analysis to analyze the incidence of
intussusception
and adenoviral epidemic trends, and compared them with fecal and respiratory adenoviral epidemic trends in the AIALSR. The trend of
intussusception
correlated with total NEAds (r = 0.635; P = 0.011), as did the fecal AIALSR adenovirus trends (r = 0.572; P = 0.026). Among the NEAd subgroups, subgroup C was dominant (P < 0.001), but subgroups B (P = 0.007) and E (P = 0.013) were also significant to
intussusception
. However, only subgroup C showed a significant epidemic correlation (r = 0.776; P = 0.001) with
intussusception
. Not respiratory but fecal AIALSR adenovirus trends correlated with the incidence of NEAds and
intussusception
. We suggest the possibility of using fecal AIALSR adenovirus data as an approximate epidemic predictor of
intussusception
.
