  • Irritable Bowel Syndrome is probably caused by fungi

    Patients with Irritable Bowel Syndrome (IBS) carry a different set of fungi in their gut compared to healthy people. This observed imbalance is related to abdominal pain complaints in IBS patients. This work was shown by researchers in The Netherlands which are based at Tytgat Institute (Academic Medical Center, Amsterdam), TNO (Zeist) and University of Maastricht.

    Until now IBS-related microbiome research almost exclusively focused on the bacterial composition of the gut. Recent investigations showed that the gut also harbors fungi, and this includes healthy people. New evidence now shows that the composition of gut fungi (the mycobiome) in IBS patients differs from healthy people. Fungal diversity as well as relative contribution of fungal species was altered. 

    A change in fungal composition was also observed in an often used IBS-like rat model, were stress induces abdominal pain. In this model, anti-fungals reversed abdominal pain and rat-to-rat poop transplantations showed that the fungal imbalance was relevant for abdominal pain. Earlier work showed that abdominal pain in IBS is induced by activation of mast cells, which are part of the immune system. The current investigations indicated that their activation is triggered by gut fungi. 

    ‘Obviously, this is not definitive proof for the role of fungi in IBS patients’ says René van den Wijngaard (Tytgat Institute) who headed the investigations. ‘But this study is an important reason to investigate further the possible role of fungi in IBS and search for new therapies that can modulate gut fungi or their interaction with the immune system’.

    IBS is a disorder where patients experience abdominal pain complaints with altered bowel habits (diarrhea or constipation) in the absence of structural or microscopic abnormalities. The worldwide prevalence of IBS is 10%. Since the exact triggers for abdominal pain complaints are unknown, there is no effective therapy at present time.

    More information can be found in the publication in Gastroenterology.

  • Relation between postoperative ileus and anastomotic leakage after colorectal resection

    After bowel surgery, anastomotic sites (where the wound is stitched together) can sometimes leak, with dangerous consequences. The reason for leakage is not always clear, so it is difficult for a surgeon to circumvent it. Together with the Catharina Hospital in Eindhoven, we have now shown what can be an important reason of this leakage in a large patient trial. Read it in the publication of Emmeline Peters et al.

  • RIP: Jeroen Oerlemans

    This weekend, we heard the sad news that fotographer Jeroen Oerlemans was killed in Syria. Jeroen was a freelance fotographer and covered several areas of conflict. In 2012, he was kidnapped for one week in Syria. His photographs are published in several well-known newspapers and Jeroen was awarded with the Silver Camera in 2008, 2010 and 2011.

    Besides the many photographs from abroad, he also made portrait photographs of individuals and groups. In 2013, Jeroen took pictures of our research group. His professional attitude was a joy to work with.

    We wish his wife, children, family and friends all the strength in these sad days.

  • A breakthrough collaboration of GSK and AMC on Bioelectronics for inflammation

    It is increasingly recognized that neuronal signals are critical players in shaping the immune response. Recent clinical trials have demonstrated therapeutic efficacy of electrical devices implanted to stimulate neuronal activity, to reduce inflammation.

    GSK Bioelectronics and AMC have now launched a 3-year collaborative program to establish the role of neuronal innervation in immune responses in chronic inflammatory disorders such as rheumatoid arthritis and inflammatory bowel disease. The project involves state of the art neuronal interfacing with the aim to establish the molecular mechanisms of neuro-immune interactions in the immune response, and enable clinical application of this technique.

    The 5FTE project team is funded by GSK Bioelectronics and closely collaborates with the Catharina Hospital in Eindhoven.
