<b><i>Introduction:</i></b> The aim of this study was to examine whether biomarkers are predictive of the adalimumab (ADA) trough level and antidrug antibody development in patients with Crohn’s disease (CD) and ulcerative colitis (UC). <b><i>Methods:</i></b> Using data obtained in a prospective, multicenter, observational study (PLANET), we assessed serial changes in a novel biomarker – leucine-rich alpha-2 glycoprotein (LRG) – during ADA treatment for patients with active CD and UC. We measured serum LRG, C-reactive protein (CRP), and fecal calprotectin (fCAL) at weeks 0, 12, 24, and 52. The ADA trough level and anti-ADA antibody (AAA) were also measured at weeks 12 and 52. Correlations between the ADA trough level, AAA, and biomarkers were examined. <b><i>Results:</i></b> In all, 34 patients with CD and 47 patients with UC were enrolled. The ADA trough level at week 12 or at the time of ADA withdrawal was 8.5 ± 3.9 in the AAA-negative group (<i>n</i> = 70) and 2.9 ± 2.7 μg/mL in the AAA-positive group (<i>n</i> = 8) (<i>p</i> &#x3c; 0.0001). The ADA trough level at week 12 or at the time of ADA withdrawal was associated with pretreatment LRG (<i>p</i> = 0.0437 and <i>r</i> = −0.23). <b><i>Conclusion:</i></b> LRG, rather than CRP or fCAL, may be a marker for predicting the trough level of ADA for patients with CD and UC treated with ADA.

AbstractPatients with inflammatory bowel disease (IBD) report fatigue more frequently than healthy population, but the precise mechanisms underlying its presence are unknown. This study aimed to evaluate the prevalence of fatigue in IBD and its relation with potential causative factors. A survey on fatigue, depression, anxiety, sleep disorders, and the presence of sarcopenia and malnutrition, was sent by email to 244 IBD outpatients of the Gastroenterology Unit of Academic Hospital of Padua. Demographics and clinical data, including the levels of fecal calprotectin (FC) and C-reactive protein (CRP), and current pharmacological treatments were obtained from patients’ medical records. Ninety-nine (40.5%) subjects answered the survey. Ninety-two (92.9%) patients reported fatigue, with sixty-six having mild to moderate fatigue and twenty-six severe fatigue. Multivariate analysis showed that abnormal values of CRP (OR 5.1), severe anxiety (OR 3.7) and sarcopenia (OR 4.4) were the factors independently associated with severe fatigue. Fatigue has a high prevalence in subject affected by IBD. Subjects with altered CRP, sarcopenia and severe anxiety appear more at risk of severe fatigue.

Abstract Background This study aimed to compare fecal calprotectin (FC) levels with other commonly used parameters as part of patient care during evaluation for inflammatory bowel disease (IBD). Methods We recruited adult IBD patients with ulcerative colitis (UC) and Crohn’s disease (CD) and compared the results of the patient’s biopsy results (i.e., inflamed versus noninflamed) for six sites (i.e., ileum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum) with concentrations of C-reactive protein (CRP), total leucocytes and fecal calprotectin (FC). Results We found that FC was significantly elevated in a concentration-dependent manner that correlated with the number of active inflammation sites reported in biopsy. Although CRP and leucocyte measurements trended upwards in line with inflammation reported from biopsy, the results were highly variable and highlighted poor reliability of these biomarkers for indicating IBD inflammation. Conclusions These results strongly suggest that FC correlates best with biopsy reports and is a superior marker than CRP and leucocytes.

AbstractLeucine-rich alpha-2 glycoprotein (LRG) may be a novel serum biomarker for patients with inflammatory bowel disease. The association of LRG with the endoscopic activity and predictability of mucosal healing (MH) was determined and compared with those of C-reactive protein (CRP) and fecal markers (fecal immunochemical test [FIT] and fecal calprotectin [Fcal]) in 166 ulcerative colitis (UC) and 56 Crohn’s disease (CD) patients. In UC, LRG was correlated with the endoscopic activity and could predict MH, but the performance was not superior to that of fecal markers (areas under the curve [AUCs] for predicting MH: LRG: 0.61, CRP: 0.59, FIT: 0.75, and Fcal: 0.72). In CD, the performance of LRG was equivalent to that of CRP and Fcal (AUCs for predicting MH: LRG: 0.82, CRP: 0.82, FIT: 0.70, and Fcal: 0.88). LRG was able to discriminate patients with MH from those with endoscopic activity among UC and CD patients with normal CRP levels. LRG was associated with endoscopic activity and could predict MH in both UC and CD patients. It may be particularly useful in CD.

Abstract Background and Aims Accelerated infliximab (IFX) induction is often based on clinical parameters as opposed to pharmacokinetics (PK). We aimed to investigate the impact of dashboard-guided optimized induction dosing on IFX durability and immunogenicity in a real-world inflammatory bowel disease (IBD) setting. Methods Pediatric and adult IBD patients were enrolled in a prospective single arm intervention trial. Cumulative data from each infusion (INF), weight, albumin, C-reactive protein, IFX dose, IFX trough level, and antidrug antibody presence were used to inform subsequent INF dosing. Forecasts driven by adaptive Bayesian modeling were generated to maintain trough levels for the third (INF3) and fourth (INF4) infusions of 17 μg/mL and 10 μg/mL, respectively. The primary outcome was proportion of patients prescribed accelerated dosing (AD) intervals by INF3 (&lt;22 days) or INF4 (&lt;49 days). Secondary outcomes included week 52 clinical and PK outcomes. Multivariate analyses and Kaplan-Meier curves compared outcomes based on adherence to dashboard forecasts. Results Of the 180 per-protocol population, AD was forecast for 41% (INF3) and 69% (INF4) of patients with median intervals of 17 (INF3) and 39 (INF4) days. Baseline age &gt;18 years, albumin &gt;3.5 g/L, and 10-mg/kg dose were independently associated with lower rates of AD by INF4. Nonadherence with the INF4 forecast (n = 39) was an independent predictor of antidrug antibody (P &lt; .0001) and IFX discontinuation (P = .0006). A total of 119 of 123 patients on IFX at week 52 were in steroid-free remission. Conclusions The application of a PK dashboard during induction can optimize dosing early to improve IFX durability and immunogenicity.

Background & Aims: Golimumab (GOL) has been recently approved in Italy for the treatment of ulcerative colitis (UC) unresponsive to standard treatments. Our aims were to assess the real-life efficacy and safety of GOL in managing UC outpatients in Italian primary Inflammatory Bowel Diseases (IBD) centres.Methods: Consecutive UC outpatients with at least 3-months follow-up were enrolled. Primary end-point was the induction and maintenance of remission in UC, defined as Mayo score ≤2, at 6-month follow-up.Results: Ninety-three patients were enrolled. At 6-month follow-up, remission was obtained in 34 (36.5%) patients. Shorter duration of disease was the only significant predictive factor of remission. Clinical response was achieved in 60 (64.5%) patients, while mucosal healing (MH) was obtained in 18 (19.3%) patients. Sixteen (47.0%) patients under remission were still under therapy with steroids. C-reactive protein and fecal calprotectin significantly dropped during the follow-up (p<0.001 for both proteins). Adverse events occurred in 4 (4.3%) patients and 3 of them stopped treatment. Colectomy was performed in only one patient (1.1%).Conclusions: Golimumab seems to be safe and effective in inducing and maintaining remission in real life UC outpatients.Abbreviations: ADA: Adalimumab; CRP: C-reactive Protein; GOL: Golimumab; FC: Fecal calprotectin; IBD: Inflammatory Bowel Diseases; IFX: Infliximab; IQR: Interquartile range; MH: Mucosal Healing; SC: Subcutaneously; TBC: Tuberculosis; TNFα: Tumor necrosis factor α; UC: Ulcerative Colitis.

Abstract Background: Fatigue is defined as an overwhelming sense of tiredness not responsive to rest or sleep, and it affects every day occupations, social functioning, and work. Patients with inflammatory bowel disease (IBD) report fatigue more frequently than healthy population, but the precise mechanisms underlying its presence are unknown. This study aimed to evaluate the prevalence of fatigue in IBD and its relation with potential causative factors. Methods: A survey consisting of different questionnaires that aimed to evaluate fatigue, depression, anxiety, sleep disorders, and the presence of sarcopenia and malnutrition, was sent by email to 244 IBD outpatients of the Gastroenterology Unit of Academic Hospital of Padua . Demographics and clinical data, including the levels of fecal calprotectin (FC) and C-reactive protein (CRP), and current pharmacological treatments were obtained from patients’ medical records. Results: Ninety-nine (40.5%) subjects answered the survey. Ninety-two (92.9%) patients reported fatigue, with sixty-six having mild to moderate fatigue and twenty-six severe fatigue. After univariate analysis, subjects reporting severe fatigue were more likely to have abnormal values of CRP (OR 3.6) and to demonstrate scores suggesting the presence of sarcopenia, malnutrition, anxiety, depression, compromised sleep quality, and lower quality of life scores. Multivariate analysis showed that abnormal values of CRP (OR 5.1), severe anxiety (OR 3.7) and sarcopenia (OR 4.4) were the factors independently associated with severe fatigue. Conclusion: Fatigue has a high prevalence in subject affected by IBD. Subjects with altered CRP, sarcopenia and severe anxiety appear more at risk of severe fatigue.
