Diagnosis and screening for anal intraepithelial neoplasia in Belgium: position statement.

Anal cancer is an uncommon malignancy, comprising only 2.5% of all gastrointestinal malignancies and similar to cervical cancer, the human papillomavirus (HPV) is responsible for the majority of anal cancers. Over the last decades there has been an up to 3-fold increased incidence seen in specific populations at risk such as persons living with HIV (PLWH), men who have sex with men (MSM), woman diagnosed with HPV-related gynaecological precancerous lesions or cancer, solid organ transplant recipients (SOTR) and patients with autoimmune diseases. Although international practice is evolving increasingly towards active screening for and treatment of anal cancer precursors in at-risk groups, currently no organised screening program is in effect in Belgium. Currently, differerent screening options as well as treatment modalities are available. Before commencing a nationwide organised screening program, essential decisions on screening strategies need to be made, based on both scientific as well as financial and logistical facts.

BSGIE survey on COVID-19 and gastrointestinal endoscopy in Belgium : results and recommendations.

BACKGROUND AND AIMS: With the first wave of the COVID-19 pandemic declining, activities in the gastrointestinal clinic are being recommenced after a period of stringent measures. Since a second COVID-19 wave is not entirely ruled out health care professionals might remain faced with the need to perform endoscopic procedures in patients with a confirmed positive or unknown COVID-19 status. With this report we aim to provide a practical relevant overview of preparation and protective measures for gastroenterologists based on the currently available guidelines and our local experience and results of a national Belgian survey, to guarantee a fast recall of an adequate infection prevention if COVID-19 reoccurs. METHODS: From the 23rd of March 2020 and the 13th of May 2020 we performed a Pubmed, Embase and Medline search, resulting in 37 papers on COVID-19 and endoscopy. Additionally, we combined these data with data acquired from the national BSGIE survey amongst Belgian gastroenterologists. RESULTS: Based on 72 completed surveys in both university and non-university hospitals, the results show (1) a dramatic (<20%) or substantial (<50%) decrease of normal daily endoscopy in 74% and 22% of the units respectively, (2) a difference in screening and protective measures between university and non-university hospitals. These findings were subsequently compared with the current guidelines. CONCLUSION: Based on new data from the BSGIE survey and current guidelines we tried to realistically represent the current COVID-19 trends in protective measures, screening and indications for endoscopy and to provide a practical overview as preparation for a possible second wave.

Spontaneous life-threatening hemobilia during acute liver failure successfully treated with transarterial embolization.

A 28-year-old patient admitted with jaundice, vomiting and deteriorating coagulopathy was diagnosed with acute liver failure. After listing for urgent transplantation, he developed Boerhaave's syndrome and massive hemobilia, two life-threatening complications. Massive hemobilia secondary to a fistula between the right hepatic artery and the right bile duct occurred several days after transjugular biopsy and was controlled with fluid resuscitation, transfusion and arterial embolization. Two days later he was transplanted successfully, and is currently doing well after more than 72 months. Aggressive treatment of potentially reversible complications during acute liver failure whilst awaiting transplantation is mandatory to allow survival of these patients.

Common variable immunodeficiency (CVID): case report and review of the literature.

Common variable immunodeficiency (CVID) is an immunodeficiency disease characterized by diminished ability to produce immunoglobulins. CVID has an estimated incidence of 1:10,000 to 1:200,000 (male:female 1:1) and usually presents in the second and third decade, although it also has a peak of incidence in childhood. The exact pathophysiology remains unclear. CVID can be associated with autoimmune, granulomatous and gastrointestinal diseases and patients have a predisposition to malignancies (especially non-Hodgkin lymphoma). Since different organ systems can be affected, all clinicians need to be aware of this entity, especially when confronted with patients with recurrent infections and/or multiple autoimmune diseases.
