BACKGROUND & AIMS:Bowel ultrasonography (BUS) is a noninvasive tool for evaluating bowel activity in Crohn's disease (CD) patients. Aim of our multicenter study was to assess whether BUS helps to monitor intestinal activity improvement/resolution following different biological therapies. METHODS:Adult CD patients were prospectively enrolled at 16 sites in Italy. Changes in BUS parameters [i.e. bowel wall thickening (BWT), lesion length, echo pattern, blood flow changes and transmural healing (TH: normalization of all BUS parameters)] were analyzed at baseline and after 3, 6 and 12 months of different biological therapies. RESULTS:One hundred eighty-eight out of 201 CD patients were enrolled and analyzed (116 males [62%]; median age 36 years). Fifty-five percent of patients were treated with adalimumab, 16% with infliximab, 13% with vedolizumab and 16% with ustekinumab. TH rates at 12 months were 27.5% with an NNT of 3.6. TH at 12 months after adalimumab was 26.8%, 37% after infliximab, 27.2% after vedolizumab and 20% after ustekinumab. Mean BWT improvement from baseline was statistically significant at 3 and 12 months (P < .0001). Median Harvey-Bradshaw index, C-reactive protein and fecal calprotectin decreased after 12 months from baseline (P < .0001). Logistic regression analysis showed colonic lesion was associated with a higher risk of TH at 3 months and a greater BWT at baseline was associated with a lower risk of TH at 3 months [P [ .03 (OR 0.70, 95% CI 0.50-0.97)] and 12 months [P [ .01 (OR 0.58, 95% CI 0.38-0.89)]. At 3 months therapy optimization during the study was the only independent factor associated with a higher risk of no ultrasonographic response [P [ .02 (OR 3.34, 95% CI 1.18-9.47)] and at 12 months disease duration [P [ .02 (OR 3.03, 95% CI 1.15-7.94)]. CONCLUSIONS:Data indicate that BUS is useful to monitor biologics-induced bowel activity improvement/ resolution in CD.

Background In a 6-year, multicenter, prospective nested case–control study, we aimed to evaluate risk factors for incident cancer in inflammatory bowel disease (IBD), when considering clinical characteristics of IBD and immunomodulator use. The secondary end point was to provide characterization of incident cancer types. Methods All incident cases of cancer occurring in IBD patients from December 2011–2017 were prospectively recorded in 16 Italian Group for the Study of Inflammatory Bowel Disease units. Each of the IBD patients with a new diagnosis of cancer was matched with 2 IBD patients without cancer, according to IBD phenotype (ulcerative colitis [UC] vs Crohn’s disease [CD]), age (±5 years), sex. Risk factors were assessed by multivariate logistic regression analysis. Results Cancer occurred in 403 IBD patients: 204 CD (CD cases), 199 UC (UC cases). The study population included 1209 patients (403 IBD cases, 806 IBD controls). Cancer (n = 403) more frequently involved the digestive system (DS; 32%), followed by skin (14.9%), urinary tract (9.7%), lung (6.9%), genital tract (6.5%), breast (5.5%), thyroid (1.9%), lymphoma (2.7%, only in CD), adenocarcinoma of the small bowel (SBA; 3.9%, 15 CD, 1 pouch in UC), other cancers (15.9%). Among cancers of the DS, colorectal cancer (CRC) more frequently occurred in UC (29% vs 17%; P < 0.005), whereas SBA more frequently occurred in CD (13% vs 6.3% P = 0.039). In CD, perforating (B3) vs non-stricturing non-perforating (B1) behavior represented the only risk factor for any cancer (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.33–4.11). In CD, risk factors for extracolonic cancer (ECC) were a B3 vs B1 and a stricturing (B2) vs B1 behavior (OR, 2.95; 95% CI, 1.62–5.43; OR, 1.79; 95% CI, 1.09–2.98). In UC, risk factors for ECC and for overall cancer were abdominal surgery for UC (OR, 4.63; 95% CI, 2.62–8.42; OR, 3.34; 95% CI, 1.88–5.92) and extensive vs distal UC (OR, 1.73; 95% CI, 1.10–2.75; OR, 1.99; 95% CI, 1.16–3.47). Another risk factor for ECC was left-sided vs distal UC (OR, 1.68; 95% CI, 1.00–2.86). Inflammatory bowel disease duration was a risk factor for skin and urinary tract cancers. Conclusions Perforating CD, extensive UC, and abdominal surgery for UC were identified as risk factors for overall incident cancer and for ECC. The clinical characteristics associated with severe IBD may increase cancer risk.

Objective:The clinical significance of increased serum pancreatic enzymes (PEs) in coronavirus disease 2019 (COVID-19) patients has not yet been fully understood. We aimed to investigate the frequency and the impact on clinical outcome of PE elevation and acute pancreatitis in such patients.Methods: Clinical data, laboratory tests, and cross-sectional images were analyzed from COVID-19 patients admitted to the Tor Vergata Hospital in Rome. Variables associated with PE abnormalities, intensive care unit (ICU) admission, or death were investigated through univariate and multivariate analyses and Cox proportional hazard model.Results: Pancreatic enzymes were available in 254 of 282 COVID-19 patients. Among these, 66 patients (26%) showed mild elevation of PE, and 11 patients (4.3%) had severe elevation (>3 times of the upper limit of normal). Overall, 2 patients met the diagnostic criteria for acute pancreatitis. Hepatic and renal involvements were associated with PE elevation. Multivariate analysis showed that mild and severe PE elevations were significantly associated with ICU admission (odds ratios, 5.51 [95% confidence interval, 2.36-12.89; P < 0.0001] and 26.2 [95% confidence interval, 4.82-142.39; P < 0.0001]).Conclusions: Increase in serum PE, but not acute pancreatitis, is frequent in hospitalized COVID-19 patients and associates with ICU admission.

Background Recent retrospective studies have shown that frailty is common in hospitalized patients with inflammatory bowel disease (IBD) and enhances the risk of drug-related infections, postsurgery complications, hospital readmissions, and mortality, independently of age and comorbidities. We carried out a descriptive cohort study to evaluate the frequency of frail phenotype in IBD and analyzed the risk factors associated with this condition. Methods Frail phenotype was assessed in IBD patients by using the Fried frailty phenotype. Univariate and multivariate analyses were conducted to assess the risk factors for frail phenotype. Serum levels of interleukin (IL)-6 were quantified in patients with a frail or a fit phenotype by ELISA. Results Three hundred eighty-six IBD outpatients (198 Crohn’s disease and 188 ulcerative colitis) were prospectively enrolled from December 2021 to April 2022. Frail phenotype was diagnosed in 64 of 386 (17%) IBD patients and was significantly associated with female gender, active disease, and current use of steroids. Multivariate analysis showed that active disease was a risk factor for frail phenotype (odds ratio, 11.5; 95% confidence interval, 3.9-33.9). No difference in IL-6 serum levels was seen between patients with a frail phenotype and those who were fit. Conclusions This is the first prospective study showing that frail phenotype occurs in nearly one-fifth of IBD patients. Data indicate that active IBD is an independent risk factor for frail phenotype in IBD.
