Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry

Background

Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF.

Objectives

To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients.

Design

Retrospective observational study.

Methods

Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially).

Results

Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission.

Conclusion

The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy.

Serological response and breakthrough infection after COVID-19 vaccination in patients with cirrhosis and post-liver transplant

BACKGROUND

Vaccine hesitancy and lack of access remain major issues in disseminating COVID-19 vaccination to liver patients globally. Factors predicting poor response to vaccination and risk of breakthrough infection are important data to target booster vaccine programs. The primary aim of the current study was to measure humoral responses to 2 doses of COVID-19 vaccine. Secondary aims included the determination of factors predicting breakthrough infection.

METHODS

COVID-19 vaccination and Biomarkers in cirrhosis And post-Liver Transplantation is a prospective, multicenter, observational case-control study. Participants were recruited at 4-10 weeks following first and second vaccine doses in cirrhosis [n = 325; 94% messenger RNA (mRNA) and 6% viral vaccine], autoimmune liver disease (AILD) (n = 120; 77% mRNA and 23% viral vaccine), post-liver transplant (LT) (n = 146; 96% mRNA and 3% viral vaccine), and healthy controls (n = 51; 72% mRNA, 24% viral and 4% heterologous combination). Serological end points were measured, and data regarding breakthrough SARS-CoV-2 infection were collected.

RESULTS

After adjusting by age, sex, and time of sample collection, anti-Spike IgG levels were the lowest in post-LT patients compared to cirrhosis (p < 0.0001), AILD (p < 0.0001), and control (p = 0.002). Factors predicting reduced responses included older age, Child-Turcotte-Pugh B/C, and elevated IL-6 in cirrhosis; non-mRNA vaccine in AILD; and coronary artery disease, use of mycophenolate and dysregulated B-call activating factor, and lymphotoxin-α levels in LT. Incident infection occurred in 6.6%, 10.6%, 7.4%, and 15.6% of cirrhosis, AILD, post-LT, and control, respectively. The only independent factor predicting infection in cirrhosis was low albumin level.

CONCLUSIONS

LT patients present the lowest response to the SARS-CoV-2 vaccine. In cirrhosis, the reduced response is associated with older age, stage of liver disease and systemic inflammation, and breakthrough infection with low albumin level.

EUS-guided gastroenterostomy versus duodenal self-expandable metal stent for malignant gastric outlet obstruction: results from a nationwide multicenter retrospective study (with video)

BACKGROUND AND AIMS

Traditionally, palliative treatment of malignant gastric outlet obstruction (GOO) has been surgical, but surgical treatment carries significant morbidity and mortality rates. Endoscopic placement of a duodenal self-expandable metal stent (D-SEMS) has been proven to be successful for this indication in the short term. However, D-SEMSs are likely to malfunction over time. EUS-guided gastroenterostomy (EUS-GE) may help overcome these limitations. We aimed to evaluate stent failure-free survival at 3 months.

METHODS

A nationwide multicenter, observational study of D-SEMS and EUS-GE procedures for patients with malignant GOO was conducted at 7 academic centers from January 2015 to June 2020. Stent failure-free survival at 1, 3, and 6 months; technical and clinical success; adverse events (AEs); and patient survival were evaluated in both groups and compared.

RESULTS

Ninety-seven patients were included in the D-SEMS group and 79 in the EUS-GE group. Pancreatic cancer was the main underlying malignancy in 53.4%. No statistically significant differences regarding technical (92.8% vs 93.7%) or clinical success (83.5% vs 92.4%) were found. AE rates did not differ between groups (10.3% vs 10.1%), although 2 events in the EUS-GE group required surgical management. Patients in the EUS-GE group had improved stent patency when compared with those patients in the D-SEMS group at 3 months (92.23% vs 80.6%; adjusted hazard ratio, .37; P = .033).

CONCLUSIONS

EUS-GE seems to have improved patency outcomes when compared with D-SEMS placement for palliative treatment of malignant GOO. Prospective trials are needed to fully compare their efficacy and AE profile.

Outcomes of drug-induced acute pancreatitis: a ten-year experience of an academic center

BACKGROUND

drug-induced pancreatitis is an unexplored entity.

METHODS

a retrospective cohort study was performed at a referral center. Patients with drug-induced acute pancreatitis between 2008 and 2018 were included. Baseline patient characteristics, involved drugs, clinical course and recurrence were analyzed.

RESULTS

drug-induced pancreatitis represented 2.8 % of acute pancreatitis (47/1,665) and 18 different drugs were involved (thiopurines 61.8 %). The latency period was less than one month in 87.2 % of cases. Pancreatitis was mild in 89.3 % and recurrence risk was 2.3 %.

CONCLUSION

drugs are a rare cause of pancreatitis, which mostly occurs within the first month of treatment, is usually mild and is associated with a low risk of recurrence.

[Anisakiasis as differential diagnosis of acute abdominal pain at the emergencydepartment]

Anisakiasis is a zoonosis with an increasing prevalence, especially in European countries, caused by the ingestion of the nematode of the genre Anisakis in its third larvae stage after consuming undercooked or raw fish. It may produce gastrointestinal symptoms and hypersensitivity reactions to the proteins of the worm. We present a case of gastric anisakiasis accompanied by hypersensitivity symptoms (gastroallergic form) after the ingestion of raw fish.
