  • Inborn Errors of Bile Acid Metabolism
    Reprinted with permission from Thieme Medical Publishers (Seminars Liver Dis. 2007 Aug;27(3):282-294) Homepage at www.thieme.com Inborn Errors of Bile Acid Metabolism James E. Heubi, M.D.,1 Kenneth D.R. Setchell, Ph.D.,1 and Kevin E. Bove, M.D.1 ABSTRACT Bile acids are synthesized by the liver from cholesterol through a complex series of reactions involving at least 14 enzymatic steps. A failure to perform any of these reactions will block bile acid production with failure to produce ‘‘normal bile acids’’ and, instead, result in the accumulation of unusual bile acids and intermediary metabolites. Failure to synthesize bile acids leads to reduced bile flow and decreased intraluminal solubilization of fat and fat-soluble vitamins. In some circumstances, the intermediates created because of blockade in the bile acid biosynthetic pathway may be toxic to hepatocytes. Nine recognized inborn errors of bile acid metabolism have been identified that lead to enzyme deficiencies and impaired bile acid synthesis in infants, children, and adults. Patients may present with neonatal cholestasis, neurologic disease, or fat and fat-soluble vitamin malabsorption. If untreated, progressive liver disease may develop or reduced intestinal bile acid concentrations may lead to serious morbidity or mortality. This review focuses on a description of the disorders of bile acid synthesis that are directly related to single defects in the metabolic pathway, their proposed pathogenesis, treatment, and prognosis.

    pat hways Bile acid malabsorption: colesevelam Evidence summary Published: 29 October 2013 nice.org.uk/guidance/esuom22 Key points from the evidence The content of this evidence summary was up-to-date in October 2013. See summaries of product characteristics (SPCs), British national formulary (BNF) or the MHRA or NICE websites for up-to-date information. Summary The use of colesevelam for bile acid malabsorption is reported in 2 small case series (n=45 and n=5), which found that colesevelam improved diarrhoea and gastrointestinal symptoms in people with this condition. A randomised controlled trial (RCT) found no improvement in outcomes with colesevelam in 24 women with diarrhoea-predominant irritable bowel syndrome, 4 of whom had evidence of bile acid malabsorption. However, the study may have been underpowered to detect any differences between the groups. Colesevelam appears to be well tolerated; the most frequent adverse effects are flatulence and constipation. Regulatory status: off-label © NICE 2018. All rights reserved.

  • Irritable Bowel Syndrome (IBS): Introduction
    Irritable Bowel Syndrome (IBS): Introduction Irritable Bowel Syndrome (IBS), which is classified as a functional gastrointestinal disorder, is a chronic condition of the lower gastrointestinal tract (Figure 1) that affects as many as 15% of adults in the United States. Not easily characterized by structural abnormalities, infection, or metabolic disturbances, the underlying mechanisms of IBS have for many years remained unclear. Recent research, however, has lead to an increased understanding of IBS. As a result, IBS is now considered an organic and, most likely, neurologic bowel disorder. IBS is often referred to as spastic , nervous or irritable colon . Its hallmark is abdominal pain or discomfort associated with a change in the consistency and/or frequency of bowel movements. Although the causes of IBS have not to date been fully elucidated, it is believed that symptoms can occur as a result of a combination of factors, including visceral hypersensitivity, altered bowel motility , neurotransmitters imbalance, infection and psychosocial factors (Figure 2). Figure 1. Location of the colon in the body. Figure 2. Possible causes of Irritable Bowel Syndrome . The frequency of IBS in any given population depends, in part, on the ethnic and cultural background of the population being studied, and the criteria used to diagnose the disease. Eight to 20% of adults in the Western world report symptoms consistent with IBS (60-70% of these are women). In the United States, as many as 15% of adults (about 35 million people) report IBS symptoms (note: the frequency of IBS among Caucasian, African American and Hispanic populations is relatively consistent). Asia and Africa have similar rates to those in the United States, and the Western world in general.

Orsola-Malpighi Polyclinic and University of Bologna, *Corresponding Author: Prof. Mauro Bortolotti, Postal address: via Massarenti 48, 40138 Bologna, Italy. Abstract Purpose: The idiopathic bile acid diarrhoea(BAD) is a rather frequent finding in diarrhoea-predominant irritable bowel syndrome(IBS-D) patients and is responsive to cholestiramine.The purpose is to investigate a possible pathophysiological role of gallbladder motor activity in patients with idiopathic BAD. Methods: We examined the gallbladder volume before and 15’,30’,45’ and 60’ after a 300 Kcal meal with a D3 sonographic technique in 52 IBS-D patients with postprandial diarrhoea responsive to cholestyramine(group R).The ejection fraction at various times was calculated and compared by means of Student t test with the corresponding values of 32 healthy subjects(group C)and of 14 IBS-D patients not responsive to cholestiramine(group NR).The ejection fraction at various times of each patient of group R was examined whether fell in the 99% confidence interval(CI) of the corresponding means of group C. Results: The gallbladder ejection fractions of the group R were significantly higher than those of the group C,at 30’,45’ and 60’, and than those of group NR, at 15’, 30’ and 60’.During all time periods nearly 50% of group R patients were above the CI upper limit and about 10% below the lower limit,whereas at 15’ about 44% was above the upper CI limit and at 60’about 17% remained below the CI lower limit.
