[Pathogenicity of fungi in the intestines--current status of the discussion].
The hypothesis that colonization of the intestinal tract by yeasts (e.g. Candida albicans) can lead to disease in immunocompromised individuals is currently being discussed controversially. Proponents assume that toxins produced by the fungi can trigger such complaints as irritable bowel syndrome of the chronic fatigue syndrome, and that such chronic or recurrent infections may be caused by an intestinal reservoir of yeasts. Opponents of the hypothesis, however, point out that no hard data on the pathogenetic significance of an intestinal reservoir of yeasts are available, controlled studies have failed to demonstrate the effectiveness of antifungal treatment. Discussions are however, hampered by a lack of objective data. The postulated pathomechanisms therefore need to be clarified, diagnostic criteria developed, and the efficacy of the proposed therapeutic measures shown by controlled studies. Until this has been done, assumption about the pathogenicity of yeasts in the bowel, cannot be taken as a basis for binding therapeutic recommendations.
