RESUMEN
BACKGROUND AND AIM: Dedicated studies evaluating the impact of COVID-19 on outcomes of pancreatobiliary IgG4 related disease (IgG4-RD) patients are scarce. Whether COVID-19 infection or vaccination would trigger IgG4-RD exacerbation remains unknown. METHODS: Pancreatobiliary IgG4-RD patients ≥ 18 years old with active follow-up since January 2020 from nine referral centers in Asia, Europe, and North America were included in this multicenter retrospective study. Outcome measures include incidence and severity of COVID-19 infection, IgG4-RD disease activity and treatment status, interruption of indicated IgG4-RD treatment. Prospective data on COVID-19 vaccination status and new COVID-19 infection during the Omicron outbreak were also retrieved in the Hong Kong cohort. RESULTS: Of the 124 pancreatobiliary IgG4-RD patients, 25.0% had active IgG4-RD, 71.0% were on immunosuppressive therapies and 80.6% had ≥ 1 risk factor for severe COVID. In 2020 (pre-vaccination period), two patients (1.6%) had COVID-19 infection (one requiring ICU admission), and 7.2% of patients had interruptions in indicated immunosuppressive treatment for IgG4-RD. Despite a high vaccination rate (85.0%), COVID-19 infection rate has increased to 20.0% during Omicron outbreak in the Hong Kong cohort. A trend towards higher COVID-19 infection rate was noted in the non-fully vaccinated/unvaccinated group (17.6% vs 33.3%, P = 0.376). No IgG4-RD exacerbation following COVID-19 vaccination or infection was observed. CONCLUSION: While a low COVID-19 infection rate with no mortality was observed in pancreatobiliary IgG4-RD patients in the pre-vaccination period of COVID-19, infection rate has increased during the Omicron outbreak despite a high vaccination rate. No IgG4-RD exacerbation after COVID-19 infection or vaccination was observed.

Introduction: We aimed to describe the extrapulmonary manifestations of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, including their frequency, onset with respect to respiratory symptoms, pathogenesis and association with disease severity. Methods: We searched the MEDLINE and Embase databases for SARS-CoV-2-related studies. Meta-analysis, observational studies, case series and case reports published in English or Chinese between 1 January 2020 and 1 May 2020 were included. Reports with only paediatric or obstetric cases were excluded. Results: 169 articles were included. Early manifestations (preceding respiratory symptoms until Day 6 of onset) included olfactory and gustatory disturbance (self-reported in up to 68% and 85% of cases, respectively), gastrointestinal symptoms (up to 65.9%) and rash (up to 20.4%). From Day 7 onwards, hypercytokinaemia, paralleled multi-organ complications including acute cardiac injury (pooled incidence of 17.7% in 1,412 patients, mostly with severe disease and 17.4% mortality), kidney and liver injury (up to 17% and 33%, respectively) and thrombocytopenia (up to 30%). Hypercoagulability resulted in venous thromboembolic events in up to 31% of all patients. Uncommon disease presentation and complications comprised Guillain-Barré syndrome, rhabdomyolysis, otitis media, meningoencephalitis and spontaneous pneumomediastinum. Conclusion: Although the systemic manifestations of SARS-CoV-2 infection are variegated, they are deeply interwoven by shared mechanisms. Two phases of extrapulmonary disease were identified: (a) an early phase with possible gastrointestinal, ocular and cutaneous involvement; and (b) a late phase characterised by multiorgan dysfunction and clinical deterioration. A clear, multidisciplinary consensus to define and approach thromboinflammation and cytokine release syndrome in SARS-CoV-2 is needed.

Training of endoscopic ultrasound (EUS) in Asia faces challenges of the ever-increasing demand for skills to handle a growing range of both diagnostic and interventional EUS procedures, and a continual shortage of EUS training programs. To keep up with the pace of development in EUS, more short-term EUS programs have been conducted across Asia in recent years. In this aspect, the Asian EUS Group (AEG) has taken the lead to fast-track the dissemination of EUS knowledge and skills across Asia through its multinational network of training centers. AEG's programs are brought to wherever there is demand. Its versatile modular structure allows the program to be easily customized and scaled up or down to align to local needs, making it highly adaptable to the changing and varying needs in different countries. Even with the current pandemic situation, it has been able to continue its training efforts through the use of technology, including webinars, and live case demonstration.

The COVID-19 pandemic is a unique challenge that has disrupted endoscopy training. Initial infection control measures aimed at protecting patients and staff meant nonessential endoscopic activity was suspended in many countries. The decrease in elective caseload from the pandemic also reduced training numbers during this period. While hands-on training took a backseat, more efforts were directed to didactic training of cognitive competencies. We review the literature describing the impact of COVID-19 on endoscopy training and summarize key measures aimed at mitigating this effect. These include leveraging on web-based didactic material and video-conferences, increased use of simulation and models to hone technical competencies, and a shift in focus from numbers-based accreditation to competency-based accreditation. While COVID-19 was hoped to be short-lived, it is clear the impact is long-lasting. Hence, it is crucial for training programs to take stock of how endoscopy training is evolving and use this opportunity to implement new paradigms into their endoscopic training curricula. COVID-19 might just be the catalyst that transforms endoscopy training into a new digital era.

BACKGROUND: Hepatocellular carcinoma with biliary ductal invasion is rare and associated with a significantly lower survival rate. CASE PRESENTATION: We present an unusual case of a patient with hepatocellular carcinoma and biliary invasion, who had his diagnosis confirmed by histological analysis from tissue extracted by endoscopic retrograde cholangiopancreatography. An 87-year-old male presented with a 1-day history of right upper quadrant pain and jaundice. His past medical history included recurrent gallstone cholangitis and a previous cholecystectomy. An abdominal CT demonstrated a dilated intrahepatic biliary tree with left proximal intrahepatic hyperdensities, as well as a 3 cm hepatocellular carcinoma. He was initially suspected to have concurrent gallstone cholangitis and a newly diagnosed hepatocellular carcinoma. Endoscopic retrograde cholangiopancreatography and balloon trawling of the intraductal lesions extracted necrotic tumour-like tissue which was histologically consistent with hepatocellular carcinoma. The extraction of the intra-biliary portion of HCC resulted in complete resolution of his jaundice, enabling further treatment with nivolumab, which would not have been possible if the obstruction was not cleared. The patient is currently well and has completed his 6th cycle of nivolumab. CONCLUSION: Obstructive jaundice is an uncommon presentation for patients with HCC. it is key for clinicians to be aware of the possibility of intrabiliary invasion in order obtain an early diagnosis and to reduce any delay in treatment.
