Abstract: | BACKGROUND: Marmosets in captivity are highly susceptible to wasting marmoset syndrome (WMS), the aetiology of which is still not fully determined. METHODS: The level of IgA-gliadin antibodies (IgA-AGA), of IgA-containing circulating immune complexes (IgA-CIC), and the degree of glomerular IgA deposits were compared between marmosets suffering from WMS and animals not affected by the disorder. RESULTS: Both IgA-AGA and IgA-CIC were demonstrable in all groups of monkeys investigated. IgA-AGA and IgA-CIC were significantly higher in monkeys with WMS than in non-affected animals. There was a significant correlation between the glomerular IgA-deposition and titre of IgA-AGA. The group of marmosets strongly positive for glomerular IgA deposits comprised significantly more animals suffering from WMS than the group without deposits. In the diet of the animals a considerable amount of gliadin-like cereal proteins was assayed. CONCLUSIONS: There are several parallels between the human disorders (coeliac disease and IgA-nephropathy/Berger's disease) and the changes observed in WMS. It should be further investigated if WMS in marmosets is a suitable animal model for both human diseases. |
