Brief Summary

Zeolite clinoptilolite is a volcanic mineral from the group of zeolites. The porous structure is associated with a large inner surface. Due to the anionic framework charge, ions (e.g., Pb\^2+) can be absorbed or exchanged. The specific Panaceo PMA zeolite is approved as a class IIa medical device for the repair of the intestine inner lining. It is CE certified and complies with the relevant European Union regulations in terms of safety and effectiveness. Zeolite is known for its absorbing properties. Because of these properties and the results of several human studies, it warrants the investigation of possible effects on specific indications in human medicine, e.g. irritable bowel syndrome. The diagnosis "irritable bowel syndrome (IBS)" is according to the ROME Foundation, an US medical society. IBS is a disorder with dysfunction of the bowels, a latent inflammation is discussed. The present study aims to evaluate the following effects in patients with IBS:

  • Primary endpoint: effect on the symptoms of IBS.
  • Secondary endpoint: intestinal wall permeability, integrity of the tight junctions as measured by the change in zonulin concentration in the stool.
  • Further endpoints:
  • Inflammation parameters and anti-inflammatory laboratory parameters.
  • Biodiversity of the gastrointestinal microbiome.
  • histamine-associated parameters.
  • Constipation as a possible side effect. For this purpose, a double-blind randomized controlled trial (RCT) is realized prospectively in a monocentric outpatient-controlled study. The subjects take the test compound daily (verum, reference substance) for 12 weeks and document the intake of the study-substance, intake of medications, stool-frequency and consistency. They receive "before" and "after" the intervention phase a blood and stool analysis for the determination of parameters for intestinal wall integrity (zonulin) inflammation (hsCRP, interleukin-10, calprotectin), histamine metabolism, microbiome diversity. The pilot study is realized ahead of the detailed planning of a later main study.

Interventions

ZeoliteOTHER

The natural zeolite clinoptilolite is of volcanic origin. The mineral belongs to the group of zeolite minerals. Zeolites are silicates with a microporous structure. This results in a stable structure with nanometer-sized cavities that pass through the natural zeolite clinoptilolite - comparable to a mineral sponge. Due to the numerous pores and channels, the mineral has a large internal surface and it can absorb molecules that are smaller in diameter than the pore openings. Since zeolite clinoptilolite has an anionic charge, there are cations such as Na +, K +, Ca 2+, Mg 2+ which can be exchanged for other ions (e.g., Pb\^2+) in the cavities for electrical charge balance. In particular, the ion exchange capacity is essential for the effect and is used in many areas.
