What is the inflammatory bowel disease?
Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory gastrointestinal disorders commonly thought to predispose to vitamin B 12 (cobalamin, Cbl) deficiency. The most important clinical manifestations of Cbl deficiency include nervous system dysfunction and megaloblastic anemia. 1,–3 Dietary Cbl must bind gastric-derived intrinsic factor (IF) for its absorption in the distal ileum. 3 CD can affect any segment of the gastrointestinal tract, whereas UC is confined to colon. One third to half of the patients with CD have isolated ileal disease and 30% to 55% have ileocolonic disease. 3,–5 Because ileal disease or resection may mediate Cbl malabsorption, patients with CD are assumed to be at greater risk for deficiency.
What is a CBL deficiency?
Biochemical Cbl deficiency is defined as low serum Cbl levels with confirmatory biomarker elevations (methylmalonic acid [MMA] and homocysteine [Hcy]). 11 These biomarker elevations confirm intracellular Cbl deficiency because they are substrates of reactions catalyzed by Cbl. Clinical deficiency is defined as a biochemical deficiency with megaloblastic anemia or neurological symptoms . 11,–14 The majority of Cbl deficiency is found in asymptomatic individuals without megaloblastic anemia. 11 This has been termed subclinical Cbl deficiency but is referred to as isolated biochemical deficiency here.
What is systematic review of CBL deficiency in CD and UC?
This systematic review of Cbl deficiency in CD and UC included studies analyzing both serum Cbl levels and absorption tests.
What is the purpose of a systematic review of CBL deficiency?
This systematic review aims to determine the risk of Cbl deficiency in both CD and UC, the specific disease-related risk factors for Cbl deficiency and the optimal management strategy. Definitions of Cbl deficiency employed in current literature were analyzed. Based on current literature, we have suggested an algorithm for evaluation and management of Cbl deficiency in IBD.
What biomarkers are used to diagnose CBL deficiency?
11,14,18 These stipulate that the diagnosis of Cbl deficiency in asymptomatic individuals should include 1 biomarker of circulating Cbl (serum Cbl or holotranscobalamin II) and 1 functional biomarker (MMA or Hcy) to confirm intracellular Cbl depletion. 11,14 Despite this, serum Cbl alone is still commonly used to screen for deficiency. 1,8,19 The sensitivity and specificity of serum Cbl are poor for isolated biochemical deficiency. 11,16,20,–24 A recent article in the New England Journal of Medicine outlined that false positive and negative rates may approach 50%. 25 When measuring serum Cbl, tests and cutoffs vary over time and between centers. 11 Furthermore, methodology is frequently suboptimal, leading to diagnostic misclassifications. 11 The Schilling's test helps to elucidate whether malabsorption occurs but does not help quantify the effect of this malabsorption on body stores. However, this test has largely disappeared for various reasons and is rarely available. 17, Table 1 outlines the NHANES diagnostic criteria and standard cutoff values for Cbl deficiency. The standard lower limit cutoff for serum Cbl is 148 pmol/L. 1,11,16 Normal upper limit cutoffs for MMA and Hcy are 270 nM/L 11,16 and 15 μmol/L, 26,27 respectively. Using these cutoffs, multiple population-based studies demonstrate deficiency rates ranging from 5% to 12%. 11
How to treat CBL malabsorption?
25 To achieve this, injected Cbl has traditionally been used with 10% of injected doses being retained in the body. 25 However, high-dose oral treatment has also been shown to be effective. 25 Oral Cbl can be absorbed by passive diffusion, even in patients with malabsorption. Oral doses of 1000 μg typically deliver 5 to 40 μg to the body. 25,28 Multiple randomized trials compared oral doses of 1000 to 2000 μg daily with parenteral therapy in patients with pernicious anemia, atrophic gastritis, or a history of ileal resection. At 3 to 4 months, both groups had symptom resolution, but oral therapy yielded higher Cbl levels and lower MMA levels than parenteral Cbl. 25,29,–31
Is CBL deficiency in CD a risk?
The risk of Cbl deficiency in CD is uncertain, making management decisions difficult. Screening for Cbl deficiency as part of routine follow-up visits for CD is often suggested. 6,32,–36 Furthermore, suggestions to follow and treat Cbl deficiency in IBD as in autoimmune gastritis have been made. 25 These measures may not be justified in all patients. Rather than using NHANES guidelines for diagnosis, gastroenterologists often manage patients with CD with isolated asymptomatic low serum Cbl with prolonged and frequently unjustified parenteral therapy associated with increased time and cost expenditures. 37,38
