From 30 to 70% of patients with Crohn's disease (CD) may develop perianal fistulas during their lifetime. The medical and surgical management of this complication is challenging, and its treatment ...still gives unsatisfactory results. However, recent studies on adipose-derived mesenchymal stem cells have proven their anti-inflammatory and immuno-modulatory potential, representing a new promising tool in the treatment of such stubborn disease. We report our initial experience with three patients who had recurrent perianal CD treated with local infiltration of stem cell darvadstrocel (Alofisel). All the patients had a long history of perianal disease refractory to multiple medical and surgical treatments. The preoperative workup included transperineal ultrasound (TP-US), pelvic MRI, and colonoscopy that ruled out active proctitis in all the patients. The post-treatment follow-up included clinical assessment at 1, 3, and 6 months with repeated MRI and TP-US at 6 months. At 6 months, 2 patients had a clinical response despite radiological persistence of fistula tracts, while one patient presented perianal fistula recurrence complicated by perianal abscess. Although our experience is limited to 3 patients and a short follow-up, our results confirm that darvadstrocel injection is a safe procedure, with a good clinical response in most of the patients, but that it apparently had no effect on the anatomical modification of the fistula tracts. Long-term results, with a rigorous assessment of anatomical lesions, are still needed to support the promising data of the literature.
Crohn's disease (CD) is an inflammatory chronic bowel disorder; it can involve the whole gastrointestinal tract, but its localization in the ileum or colon is most common. The reference standard for ...the diagnosis of CD is ileocolonoscopy with histologic assessment. The reference standard for the detection of any complications is surgery. However, imaging techniques have an important role both in the detection/localization of CD and in the follow-up of CD patients. In the last few years, the technical development of ultrasound equipment, the advent of new technologies such as elastography and mostly the increased expertise of sonographers have boosted the role of bowel ultrasound in assessment of the gastrointestinal tract. In fact, bowel ultrasound is particularly attractive thanks to its widespread availability, non-invasiveness, low cost and good reproducibility, as it can be easily repeated during follow-up. The aim of this article is to provide an extensive overview of the actual role of bowel ultrasound in the detection and follow-up of patients with CD.
Transmural healing is a long-term target for patients with Crohn's disease. Factors contributing to its promotion are poorly understood. This study assessed factors correlating with transmural ...healing based on intestinal ultrasound, in patients in long-term clinical remission on anti-TNF.
68 consecutive Crohn's patients on adalimumab (50) or infliximab (18) therapy with clinical remission ≥1 year were recruited and assessed for clinical features, trough serum levels of anti-TNF and intestinal ultrasound findings. Univariate analysis and multivariate binary logistic regression analysis identified variables independently associated with bowel wall thickening behavior.
Sixty eight patients were in remission for a mean of 4.1 years. Thirty-six patients (52.9 %) showed anti-TNF trough levels below the normal threshold. Twenty-two patients (38.4 %) showed transmural healing, 32 (47.1 %) transmural response, and 26 (38.2 %) no treatment response. Transmural healing correlated with higher BMI and lower baseline bowel wall thickening; transmural response correlated with short Crohn's disease duration, high drug levels, and with non-stricturing phenotype. Treatment non-response correlated with lower BMI, lower drug levels, higher baseline bowel wall thickening, and stricturing phenotype.
Lack of transmural healing in stable remission Crohn's patients on anti-TNF therapy is multifactorial, mainly due to low anti-TNFs trough levels, development of strictures, and higher baseline bowel wall thickening at treatment initiation.

The reference standard for assessing transjugular intrahepatic portosystemic shunt (TIPS) function is venography with portosystemic pressure gradient (PPG) measurement. This procedure is invasive and ...expensive; thus, we assessed the feasibility, reproducibility and diagnostic accuracy of color-Doppler ultrasound (CDUS) and spleen and liver stiffness (LS) measurements for identifying TIPS dysfunction. Twenty-four patients (15 undergoing TIPS placement and nine undergoing TIPS revision) consecutively underwent CDUS examination and LS and spleen stiffness (SS) determination by transient elastography (TE) and point shear-wave elastography (pSWE). All parameters were taken before TIPS placement/revision (1–15 d before) and 24 h after, just before revision by venography. pSWE inter-observer agreement was assessed by intra-class correlation coefficient (ICC). CDUS and elastographic data were correlated (Pearson coefficient) with pressure gradients (hepatic venous pressure gradient HVPG, PPG). Main determinants of TIPS dysfunction were investigated by linear regression. Forty-nine paired examinations were performed in total: 49 (100%) SS reliable measurements by pSWE and 38 (88%) by TE. The ICC for pSWE values was 0.90 (95% confidence interval CI 0.81‒0.94). SS values significantly correlated with HVPG and PPG (R = 0.51, p = 0.01). The area under the Receiver-Operating Characteristic (AUROC) curve of SS for diagnosing TIPS dysfunction was 0.86 (95% CI 0.70‒0.96) using a 25 kPa cutoff. At multivariate analysis, the flow direction of the intrahepatic portal vein branches and SS values were independently associated to TIPS dysfunction. The intrahepatic portal vein branches flow direction and SS value are two simple, highly sensitive parameters accurately excluding TIPS dysfunction. SS measurement by pSWE is feasible, reproducible and both positively and significantly correlates with HVPG and PPG values.
It is unclear whether patients with inflammatory bowel disease (IBD) are at increased risk of COVID-19.
This observational study compared the prevalence of COVID-19 symptoms, diagnosis and ...hospitalization in IBD patients with a control population with non-inflammatory bowel disorders.
This multicentre study, included 2733 outpatients (1397 IBD patients and 1336 controls), from eight major gastrointestinal centres in Lombardy, Italy. Patients were invited to complete a web-based questionnaire regarding demographic, historical and clinical features over the previous 6 weeks. The prevalence of COVID-19 symptoms, diagnosis and hospitalization for COVID-19 was assessed.
1810 patients (64%) responded to the questionnaire (941 IBD patients and 869 controls). IBD patients were significantly younger and of male sex than controls. NSAID use and smoking were more frequent in controls. IBD patients were more likely treated with vitamin-D and vaccinated for influenza. Highly probable COVID-19 on the basis of symptoms and signs was less frequent in the IBD group (3.8% vs 6.3%; OR:0.45, 95%CI:0.28–0.75). IBD patients had a lower rate of nasopharyngeal swab-PCR confirmed diagnosis (0.2% vs 1.2%; OR:0.14, 95%CI:0.03–0.67). There was no difference in hospitalization between the groups (0.1% vs 0.6%; OR:0.14, 95%CI:0.02–1.17).
IBD patients do not have an increased risk of COVID-19 specific symptoms or more severe disease compared with a control group of gastroenterology patients.

Objectives: ElastPQ®-pSWE is an ultrasound technique developed to stage disease severity in patients with chronic liver diseases. Little data is available about its application to the pancreas.
We ...aimed to assess the feasibility and reproducibility of pancreatic stiffness (PS) measurements in patients with chronic pancreatitis and their relationship with clinical and laboratory data.
52 consecutive patients with chronic pancreatitis (CP) (40 males; median age 60 years) underwent hepatic and pancreatic pSWE. Liver stiffness was measured by transient elastography, 42 healthy subjects being controls (25 males; median age 54 years). Pancreatic pSWE inter-observer agreement was analyzed by intraclass correlation coefficient (ICC). The effects of clinical, laboratory and US data on PS measurements were evaluated by linear regression.
pSWE was feasible in all the CP patients, but one. Pancreatic stiffness was significantly higher in CP patients than healthy controls (4.3 ± SD 2.4 vs. 2.8 ± SD 1.1 kPa, respectively, p = 0.001). Significantly higher values in the CP group were observed in patients with longer disease duration (>10 vs. ≤10 years) (5.8 ± SD 4 vs. 3.9 ± SD 1.5 kPa, respectively, p = 0.01), on chronic analgesic drugs (6.0 vs. 3.5 kPa, p < 0.05) and with lower body weight (p < 0.05, r = −0.38). At multivariate analysis all the three variables resulted independently associated to the pancreatic stiffness value. The ICC for PS was 0.77.
ElastPQ®-pSWE is promising and reproducible in assessing pancreatic stiffness, which mainly reflects disease length and severity. Accordingly, its use is of potential value in stratifying CP patients by identifying those with a more serious degree of disease.

Background and aim
Crohn’s disease is a life-long inflammatory disease which can impair quality of life, in particular in patients with psychiatric co-morbidities such as depression and anxiety. The ...aim of this prospective cohort study was to assess the prevalence of depression and anxiety and related risk factors in patients with quiescent Crohn’s disease.
Methods
A consecutive series of adult patients with confirmed diagnosis of Crohn’s disease, in clinical remission, were included and investigated during ambulatory visits using a standard questionnaire assessing demographic and clinical features of the disease. Within 1 month after the ambulatory visit, all patients were interviewed by phone to assess the presence of psychiatric disorders using standardized questionnaires. The questionnaire assessed the development of psychiatric disorders after the diagnosis of Crohn’s disease, the use of antidepressant or antianxiety therapy and current anxiety or depression by means of the Hospital Anxiety and Depression Scale.
Results
One hundred and ninety-five patients were included. Seventy-two (36.9 %) patients showed anxiety and/or depression symptoms, 46 (23.6 %) patients showed anxiety symptoms, 6 (3.1 %) patients showed depression symptoms and 20 (10.3 %) patients showed both symptoms. Forty-eight of these patients (58 %) were without any antidepressive or antianxiety treatment. Anxiety with or without depression was significantly correlated with female sex (
p
= 0.017), history of perianal disease (
p
= 0.003) and perianal surgery (
p
= 0.042).
Conclusion
Anxiety is a frequent, often untreated, condition in patient affected by Crohn’s disease in clinical remission. Female sex, history of perianal disease and perianal surgery are major risk factors for anxiety.

Summary
Background and aims
To assess the feasibility and reproducibility of the spleen stiffness (SS) measurement by point shear‐wave elastography (pSWE) in a cohort of compensated chronic liver ...disease (CLD) patients Cohort 1 and to investigate pSWE accuracy to predict clinically relevant portal hypertension (PH) in a consecutive cohort of cirrhotics with endoscopic signs of portal hypertension Cohort 2.
Methods
Cohort 1: 186 consecutive CLD patients underwent abdominal ultrasound (US), liver stiffness (LS) and SS measurement by pSWE and transient elastography (TE) and liver biopsy. Inter‐rater agreement of SS (pSWE) was evaluated by intra‐class correlation coefficient (ICC). Cohort 2: 80 cirrhotics underwent US, LS and SS (by pSWE and TE), hepatic venous pressure gradient (HVPG) measurement and upper endoscopy. Linear correlations between LS or SS and HVPG and linear regression analysis were performed to establish determinants of HVPG > 16.
Results
Cohort 1 SS measurement failure was 3.4% for pSWE and 13.8% for TE. For pSWE the ICC between two independent examiners was 0.74 (95% CI, 0.66‐0.80). Cohort 2: SS measurement failure was 2.5% for pSWE and 48% for TE.
HVPG and LS did not correlate. Significant correlation was observed between HVPG and SS (r = 0.36, P = .001). At multivariate analysis only the presence of ascites and SS values significantly correlated with HVPG > 16, a threshold of high mortality risk cirrhosis.
Conclusions
Measuring SS by pSWE is feasible and reproducible in CLD and is applicable in most cirrhosis cases as a promising tool of prognosis and a surrogate marker of the HVPG threshold related to survival‐ and liver‐related outcomes.
