The effect of orally administered immunoglobulin (IgAbulin((R))) on ch
ronic non-specific diarrhoea of infancy was studied in seven children,
median age 26 (21-36) months and duration of diarrhoea 32 (18-84) wee
ks. Routine laboratory tests for malabsorption and small bowel biopsie
s were taken in all children before and after 3 weeks of IgAbulin((R))
treatment. The biopsy specimens were analysed with regard to histopat
hology, electronmicroscopy, immunohistochemistry and microbiology. The
number of stools decreased from a median of 4.0 (3.0-5.0) to 1.5 (1.0
-3.5) (p < 0.05) stools per day over the study period.
