(1) Background: The CDED + PEN (partial enteral nutrition) is a promising method of nutritional treatment in active Crohn’s disease (CD). An increase in fecal calprotectin (FCP) level—a marker of mucosal inflammation—happens to be the first evidence of Crohn’s disease exacerbation that appears ahead of clinical symptoms and usually co-exists with them. In this study, we present our own experience with using the CDED + PEN in the treatment of children with CD and an increased FCP level. (2) Methods: In total, 48 children (male/female: 27/21) aged 4–17 years (median value = 13.43; IQR = 4.00) were treated with CDED + PEN between June 2019 and July 2021. The main inclusion criteria for the study was active CD defined as an FCP level ≥ 250.00 µg/g. Patients with severe clinical manifestation of CD (PCDAI >40.00), as well as ones who started any new concomitant CD treatment later than at least 4 weeks before the start of dietary intervention, were excluded from the analysis. The PCDAI and fecal calprotectin level were assessed at weeks 0 and 12. The primary endpoint was ITT normalization of FCP level, i.e., a result < 250.00 µg/g at week 12. The Wilcoxon Matched Pairs Test was used for statistical analysis. (3) Results: The normalization of the FCP level was obtained in 17 children (35.42%) and an FCP level decrease of at least 50% occurred in 26 patients (54.17%). The reduction in fecal calprotectin level between week 0 and week 12 was statistically significant with a median value of 1045.00 µg/g; IQR = 1188.00, and 363.00 µg/g; IQR = 665.00, respectively (p < 0.05). Among 29 patients who were not in clinical remission at baseline, 16 (55.17%) achieved clinical remission (PCDAI < 10.00) at week 12 and 20 (68.97%) obtained a clinical response defined as at least a 12.50 point drop in PCDAI or remission. In this group, the reduction in PCDAI between baseline and week 12 was statistically significant (median value = 20.00 points; IQR = 7.50 and 5.00 points; IQR = 5.00, respectively (p < 0.05)). All patients with a normal FCP level at week 12 were in clinical remission and 16 (94.13%) of them had a normal CRP (C-reactive protein) value. In 10 children (20.83%) the full course of 12 weeks with CDED + PEN was not completed or the concomitant therapy had been started before week 12 due to the lack of efficacy/intolerance of nutritional treatment. (4) Conclusions: The 12-week course of treatment with the CDED + PEN has a beneficial effect on the fecal calprotectin level in children with active CD. The dietary intervention led to a significant decrease in the FCP level in the studied group and to the normalization of this parameter in every third patient.
Background: Vedolizumab (vedo) is effective for induction and maintenance of remission in adults with inflammatory bowel disease (IBD). Pediatric data are still limited, especially for the youngest children with very early onset disease (VEO-IBD). The aim of this study was to assess the safety and efficacy of vedo in VEO-IBD. Methods: We performed a retrospective review of pediatric IBD patients with VEO-IBD (defined as aged <6 years) receiving vedo. Data on demographics, disease behavior, activity, and previous treatments/surgeries were collected. Disease activity was assessed using the pediatric Crohn’s disease (CD) activity index (PCDAI) for CD or pediatric ulcerative colitis (UC) activity index (PUCAI) for UC. Primary outcome was clinical response after induction therapy with vedolizumab (4th dose week). It was defined as a decrease in PCDAI of at least 12.5 points between baseline and 4th dose week for CD, and a decrease in PUCAI of at least 20 points between baseline and this time for UC. Descriptive statistics were performed to analyze the data. Results: The study included 16 patients with VEO-IBD who have received vedo: 4/16 (25%) with CD, and 12/16 (75%) with UC at the median age of diagnosis 33.7 months (6.6 months–4.5 years). Median age at vedo initiation was 6.5 years (2.2–16.5 years). Among the analyzed individuals, 56.25% had failed more than one anti-tumor necrosis factor (TNF) alfa agent. Clinical response at 4th dose week was observed in 9/16 (56.3%) patients: mean baseline PCDAI score was 34.4 ± 1.9 and 10.6 ± 1.8 after induction therapy with vedo, while PUCAI score was 26 ± 6 vs. 18 ± 8, respectively. There was improvement in patients’ nutritional state: at baseline 2/16 (12.5%) children had body mass index (BMI) below 1 percentile and no child had such BMI after induction therapy with vedo. No infusion reactions or serious adverse events/infections were reported. Conclusion: Vedolizumab is safe and effective in the medical management of pediatric patients with VEO-IBD.
Inflammatory bowel disease (IBD) is a chronic, relapsing disease of unknown etiology involving gastrointestinal tract. IBD comprises two main entities: ulcerative colitis and Crohn’s disease. Several studies showed increased risk of cardiovascular complications in chronic inflammatory disorders, especially during IBD relapses. Endothelium plays a role in physiologic regulation of vascular tone, cell adhesion, migration and resistance to thrombosis. Also, its dysfunction is associated with increased risk of atherosclerosis development. There are several potential links between chronic IBD-related inflammatory processes and the risk of cardiovascular disease, but insight into pathogenetic pathways remains unclear. We present the current concepts and review of adult and pediatric studies on the risk of CVD in IBD.
The human leukocyte antigen (HLA) allele group HLA-DQA1*05 predisposes to ulcerative colitis (UC) and is associated with the development of antibodies against infliximab in patients with inflammatory bowel disease (IBD). Therefore, we hypothesized that the presence of HLA-DQA1*05 correlates with characteristics of pediatric IBD. Within a multi-center cohort in Poland, the phenotype at diagnosis and worst flare was established and HLA-DQA1*05 status was assessed enabling genotype-phenotype analyses. HLA-DQA1*05 was present in 221 (55.1%) out of 401 children with IBD (UC n = 188, Crohn’s disease n = 213). In UC, the presence of HLA-DQA1*05 was moderately associated with a large extent of colonic inflammation at diagnosis (E4 55% more frequent in HLA-DQA1*05-positive patients, p = 0.012). PUCAI at diagnosis (p = 0.078) and the time from UC diagnosis to the first administration of biologic treatment (p = 0.054) did not differ depending on HLA-DQA1*05 status. The number of days of hospitalization for exacerbation was analyzed in 98 patients for whom sufficient follow-up was available and did not differ depending on HLA-DQA1*05 carriership (p = 0.066). HLA-DQA1*05 carriers with CD were less likely to present with both stenosing and penetrating disease (B2B3, p = 0.048) and to have active disease proximal to the ligament of Treitz (L4a) at the worst flare (p = 0.046). Future research focusing on explaining and preventing anti-TNF immunogenicity should take into account that ADA may develop not only as an isolated reaction to anti-TNF exposure but also as a consequence of intrinsic differences in the early course of UC.
Background This study aimed to evaluate the C-reactive protein-to-albumin (CRP/albumin) ratio at diagnosis of pediatric inflammatory bowel disease (IBD). Material/Methods Serum CRP/albumin ratio was calculated for patients with Crohn’s disease (CD; n=186) and ulcerative colitis (UC; n=159) aged 3–18 years. Results Patients with CD differed in CRP/albumin ratio at diagnosis in groups with quiescent, mild, moderate, and severe disease ( P =0.011). CRP/albumin ratio at diagnosis was significant in differentiating patients with severe CD from quiescent disease at diagnosis (area under the curve (AUC)=0.94, odds ratio (OR)=63.4, 95% confidence interval (CI) 7.1–569.1, P <0.0001). CRP/albumin ratio at diagnosis could moderately differentiate penetrating from non-penetrating disease behavior in CD at diagnosis (AUC=0.73, OR=6.3, 95% CI 2.0–19.3, P <0.001). Furthermore, CRP/albumin ratio at diagnosis weakly differentiated IBD patients in need of biological treatment in a step-up procedure (AUC=0.58, OR=2.1, 95% CI 1.3–3.4, P =0.022) and in need of surgery (AUC=0.63, OR=3.1, 95% CI 1.4–7.2, P =0.006). For the IBD, CRP/albumin ratio at diagnosis was weakly correlated with age at first immunosuppressive treatment (rho=0.20, P =0.018), time from diagnosis to first biological treatment (rho=−0.37, P <0.001), days spent in hospital (rho=0.26, P =0.007), number of severe relapses (rho=0.31, P =0.001), and Pediatric Crohn’s Disease Activity Index (rho=0.38, P =0.002). Conclusions The present findings add to previous studies carried out in adult patients and show that the CRP/albumin ratio at diagnosis was not significantly associated with the course of either CD or UC in children. However, CRP/albumin ratio could differentiate patients with severe CD from those with quiescent disease.
