PG - 357-64 AB - In this study we looked for the occurrence of immunoglobulin E (IgE) in feces from healthy individuals and determined the total daily excretion and day-to-day variation in IgE in feces from patients with allergy, as well as the correlation between concentrations of IgE in small samples of feces and the total amounts of IgE in feces collected over a longer period. Concentrations of IgE in extracts of small samples of dry feces correlated well with the total daily amounts of IgE in feces collected over a 3-day period. Thus, single small samples of feces can be used to measure the excretion of IgE with feces at that time. In 3 children, studied over a 5-week period, the IgE excretion varied somewhat from one day to another, but was largely within a certain range of concentrations. Addition of trypsin inhibitor to fresh feces had no influence on the IgE concentrations of the resulting fecal extracts. Less than 10% of 88 presumably healthy infants, children, and adults had detectable IgE in their feces, while 21 of 40 children with various kinds of allergy had measurable fecal IgE. Only 3 of 13 individuals who were suffering from infectious acute gastroenteritis had IgE-positive fecal extracts. This was also the case for 6 of 25 adult patients in clinical remission of ulcerative colitis or Crohn's disease. Seven of 14 adult patients with chronic pancreatitis had measurable IgE in feces, and the concentrations were up to ten times the upper limit of IgE found in healthy individuals.(ABSTRACT TRUNCATED AT 250 WORDS) FAU - Kolmannskog, S AU - Kolmannskog S FAU - Florholmen, J AU - Florholmen J FAU - Flaegstad, T AU - Flaegstad T FAU - Kildebo, S AU - Kildebo S FAU - Haneberg, B AU - Haneberg B LA - eng PT - Journal Article PT - Research Support, Non-U.S. Gov't PL - Switzerland TA - Int Arch Allergy Appl Immunol JT - International archives of allergy and applied immunology JID - 0404561 RN - 37341-29-0 (Immunoglobulin E) SB - IM MH - Adolescent MH - Child MH - Child, Preschool MH - Chronic Disease MH - Colitis, Ulcerative/*immunology MH - Crohn Disease/*immunology MH - Feces/*immunology MH - Gastroenteritis/immunology MH - Humans MH - Hypersensitivity/*immunology MH - Immunoglobulin E/*analysis MH - Infant MH - Pancreatitis/*immunology MH - Temperature EDAT- 1986/01/01 00:00 MHDA- 1986/01/01 00:01 CRDT- 1986/01/01 00:00 PHST- 1986/01/01 00:00 [pubmed] PHST- 1986/01/01 00:01 [medline] PHST- 1986/01/01 00:00 [entrez] AID - 10.1159/000234002 [doi] PST - ppublish SO - Int Arch Allergy Appl Immunol. 1986;79(4):357-64. doi: 10.1159/000234002.
