Comparative features of double-contrast barium studies in patients with isosporiasis and strongyloidiasis
1Second Department of Internal Medicine, Faculty of Medicine, Kyushu University, Fukuoka, Japan.
Objective:
To compare the gastrointestinal features of isosporiasis and strongyloidiasis.
Methods:
Two patients with isosporiasis and three patients with strongyloidiasis were assessed by double-contrast radiography of the duodenum and small intestine, with reference to histology of the duodenal biopsy specimens.
Results:
Both conditions affected the duodenum and the proximal jejunum, and showed similar radiographic changes as the diseases progressed. Thus, three patients with diarrhoea lasting 1 year or less showed only minimal or irregularly thickened mucosal folds, which seemed to result from mucosal inflammation. Two patients with long-standing disease periods (17 years and 30 years) presented a markedly granular mucosal appearance with effacement of the folds on radiography. These chronological differences in the radiographic features seemed to reflect the degree of villous atrophy.
Conclusion:
Isosporiasis has similar radiographic features of strongyloidiasis.
