Bile acid malabsorption investigated by selenium-75-homocholic acid taurine (75SeHCAT) scans, a retrospective single-centre experience.
Background: Bile acid malabsorption (BAM) is a common entity in patients experiencing chronic watery diarrhea. However, literature suggests that BAM is underdiagnosed and undertreated. In many countries 75SeHCAT is the gold standard for diagnosing BAM (1-5). The aim of this retrospective study was to investigate the frequency of BAM using 75SeHCAT scintigraphy and the response to treatment with bile acid sequestrants.
Methods: We retrospectively evaluated the clinical data of 420 patients who had a 75SeHCAT scan from January 2016 to January 2023. Electronic medical records were investigated for risk factors of BAM. BAM was defined as a 75SeHCAT retention of less than 15%. Response to bile acid sequestrants was evaluated based on outpatient clinical reports.
Results: Median age at the time of 75SeHCAT test was 47 years (range 14-87). Out of 420 patients, 192 (46%) had a positive result for BAM. Cholecystectomy and ileal resection were significant predictors for BAM (p<0.001). BAM type 1 is statistically more likely to be more severe compared to type 2 (p<0.0001) and compared to type 3 (p=0.0021). In patients who fulfilled Rome IV criteria for IBS-D or functional diarrhea, 75 out of 121 (38%) tested positive for BAM. Overall, treatment with bile acid binders was effective in 76%.
Conclusions: This retrospective study of patients who underwent SeHCAT scanning confirms that about 1/3 patients presenting with therapy-resistant chronic diarrhea in secondary care suffer from BAM. Including the test in clinical management protocols of chronic diarrhea allows early and quantitative diagnosis and treatment of BAM.
期刊介绍:
The Journal Acta Gastro-Enterologica Belgica principally publishes peer-reviewed original manuscripts, reviews, letters to editors, book reviews and guidelines in the field of clinical Gastroenterology and Hepatology, including digestive oncology, digestive pathology, as well as nutrition. Pure animal or in vitro work will not be considered for publication in the Journal. Translational research papers (including sections of animal or in vitro work) are considered by the Journal if they have a clear relationship to or relevance for clinical hepato-gastroenterology (screening, disease mechanisms and/or new therapies). Case reports and clinical images will be accepted if they represent an important contribution to the description, the pathogenesis or the treatment of a specific gastroenterology or liver problem. The language of the Journal is English. Papers from any country will be considered for publication. Manuscripts submitted to the Journal should not have been published previously (in English or any other language), nor should they be under consideration for publication elsewhere. Unsolicited papers are peer-reviewed before it is decided whether they should be accepted, rejected, or returned for revision. Manuscripts that do not meet the presentation criteria (as indicated below) will be returned to the authors. Papers that go too far beyond the scope of the journal will be also returned to the authors by the editorial board generally within 2 weeks. The Journal reserves the right to edit the language of papers accepted for publication for clarity and correctness, and to make formal changes to ensure compliance with AGEB’s style. Authors have the opportunity to review such changes in the proofs.
