Condyloma acuminatum (CA) is a manifestation of Human Papillomavirus (HPV) infection which usually occurs in genital and perianal regions. We report a 46-year-old man with an ulcerative proctitis diagnosed four years earlier, asymptomatic for a long time under azathioprine but without any follow-up for three years. A colonoscopy was performed prior to potential immunosuppressive treatment discontinuation and showed a circumferential “laterally spreading tumour” in the rectum. Surprisingly biopsies revealed a CA with a very focally high-grade intra-epithelial lesion. Azathioprine was stopped and a transanal surgical resection was performed. At guided anamnesis, patient confirmed to be a former active “men who have sex with men”. No recurrence of proctitis occurred despite azathioprine discontinuation. A retrospective review of the histological sections suggests that it was, in fact, an intestinal spirochetosis misdiagnosed as inflammatory bowel disease. Involvement of the rectal mucosa by HPV is a rare condition and this may have been promoted by inappropriate immunosuppressive treatment. [less ▲]

Background and aims: Intestinal fibrosis is a common complication of Crohn’s disease (CD) characterized by an accumulation of fibroblasts differentiating into activated myofibroblasts secreting excessive extracellular matrix. In in-vitro experiments, this myofibroblastic differentiation is elicited by a whole series of factors among which transforming growth factor β1 (TGF-β1) seems to play a key role. The potential role of the intestinal epithelium in this fibrotic process remains poorly defined. Methods: We performed a pilot proteomic study comparing the proteome of surface epithelium isolated by laser-capture microdissection in normal and fibrotic zones of resected ileal CD strictures (13 zones collected in 5 patients). The pro-fibrotic role of selected epithelial proteins was investigated through in-vitro experiments using HT-29 epithelial cells and a CCD-18Co fibroblast to myofibroblast differentiation model. Results: Proteomic study revealed an endoplasmic reticulum (ER) stress proteins increase in the epithelium of CD ileal fibrotic strictures, including Anterior gradient protein 2 homolog (AGR2), Protein disulphide isomerase A6 (PDIA6) and Endoplasmic reticulum resident protein 44 (ERP44) which are 3 protein disulphide isomerases. In HT-29 cells, tunicamycin-induced ER stress triggered AGR2, PDIA6, ERP44 as well as TGF β1 intracellular expression and their secretion. Supernatant of these HT-29 cells, pre-conditioned by tunicamycin (Tm), led to a myofibroblastic differentiation when applied on CCD-18Co fibroblasts. The application of blocking agents for AGR2, PDIA6, ERP44 or TGF β1 in the supernatant of these Tm pre conditioned HT-29 cells, attenuated the myofibroblastic differentiation induced by this supernatant, suggesting a pro-fibrotic role of these secreted epithelial proteins. Conclusions: The development of CD fibrotic strictures may involve ER stress in epithelial cells, releasing a whole set of proteins into their environment, including AGR2, PDIA6, ERP44 as well as TGF-β1, which could exercise a pro-fibrotic role through a paracrine action.

Liver transplantation (LT) remains the only curative option for patients suffering from end-stage liver disease, acute liver failure and selected hepatocellular carcinomas and access to the LT-waiting list is limited to certain strict indications. However, LT has shown survival advantages for patients in certain indications such as acute alcoholic hepatitis, hepatocellular carcinoma outside Milan criteria and colorectal cancer metastases. These newer indications increase the pressure in an already difficult context of organ shortage. Strategies to increase the transplantable organ pool are therefore needed. We will discuss here the use of HCV positive grafts as the use of normothermic isolated liver perfusion. Belgian Liver Intestine Advisory Committee (BeLIAC) from the Belgian Transplant Society (BTS) aims to guarantee the balance between the new indications and the available resources. [less ▲]

Since January 2020, the Novel Coronavirus Disease 2019 (COVID-19) pandemic has dramatically impacted the world. In March 2020, the COVID-19 epidemic reached Belgium creating uncertainty towards all aspects of life. There has been an impressive capacity and solidarity of all healthcare professionals to acutely reconvert facilities to treat these patients. In the context of liver transplantation (LTx), concerns are raised about organ donation shortage and safety, the ethics of using limited healthcare resources for LTx, selection criteria for LTx during the epidemic and the risk of de novo COVID-19 infection on the waiting list and after LTx. BeLIAC makes several recommendations to try to mitigate the deleterious effect that this epidemic has/will have on donation and LTx, taking into account the available resources, and trying to maximize patients and healthcare professionals' safety.

Ever since the initial description of the Milan criteria, used for selecting patients with hepatocellular carcinoma (HCC) for liver transplantation (LT), there has been a clear need to go further than solely morphological criteria. Tumours exceeding the Milan criteria, but presenting favourable biological behaviour, might still allow for comparable overall- and disease-free survivals after LT. As it is well established that the presence of microvascular invasion is a major factor that influences HCC recurrence after LT, several serum and tissue biomarkers in addition to imaging studies are attracting wider attention as more refined tools for selecting HCC patients for LT. A thorough review of the recent literature on the subject was conducted. In the future a combination of systemic inflammation markers, biomarkers and morphological criteria may be key to more accurate prediction of HCC recurrence after LT. This may allow LT in patients whose HCC tumours exceed the Milan criteria but have favourable biological behaviour. Further prospective studies are required in order to improve patient selection for transplantation in HCC and these could help a move towards more transparent and improved management. [less ▲]

Introduction: Liver transplantation (LT) is a major surgical procedure with large dissections and sutures of large vessels in patients with high portal hypertension and low levels of platelets and coagulation factors. In consequence, LT often requires large amounts of blood products. For religious reasons, most Jehovah's witnesses (JW) refuse infusions of any blood product, including autologous or homologous pre-donated blood, platelets, fresh frozen plasma, coagulation factor concentrates, or human albumin. However, they may accept solid organ transplantation, including LT. Aim: The authors developed experience in abdominal and oncological surgery in JW and present here their results with LT in JW patients. Methods: Over a 20-year period, 22 LT (16 DBD, 2DCD, and 4 LRLT with JW living donors) were performed in 21 JW patients and were analyzed retrospectively. All patients received perioperative iron supplementation and erythropoietin. Two patients had percutaneous spleen embolization to increase platelet level. Anti-fibrinolytic (aprotinin or tranexamic acid) was administrated during LT and meticulous surgical hemostasis was achieved, helped by argon beam coagulation. Continuous circuit cell salvage and reinfusion whereby scavenged blood was maintained in continuity with the patient's circulation, was used in all patients. Veno-venous bypass was avoided during LT to minimize the coagulation disorders. Results: There were 10 male and 11 female patients whose mean age was 48 years (ranges: 6-70). Indications for LT were HCV with (3) or without (1) HCC, PBC (2), PSC (1), HBV (2), autoimmune hepatitis (1), antitrypsin deficiency (1), sarcoidosis (2), amyloidosis (3), polycystic liver disease (1), alcoholic cirrhosis with HCC (1), cryptogenic (3), hepatic artery thrombosis (1). At transplant, mean pre-operative hematocrit was 41% (ranges: 22-50), mean platelet level was 140x103/mm3 (ranges: 33-355), and mean INR was 1.25 (ranges: 0.84- 2.18).One LRLT recipient died at day 11 from aspergillosis and anemia, and another DBD recipient at day 28 due to complications after hepatic artery thrombosis. One patient finally accepted to be transfused for severe anemia. The mean hospital stay was 31 days (10-137). Kaplan-Maier patient survival was 85%, 72%, 72% at 5, 10 and 15 years, respectively Conclusions: According to the authors' experience, LT may be successful in selected and prepared JW patients who should not be a priori excluded from this life saving procedure. The indications for LT in JW were quite different from the common indications for LT, with a low rate of alcoholic cirrhosis. The experience with this particular group of patients helped the team to reduce transfusion needs in the non-JW patients. [less ▲]

Introduction: Until now, Belgium has been considered as a low-risk country for alveolar echinococcosis (AE). However it was recently demonstrated by necropsy series that up to 51% of the red foxes (Vulpes vulpes) may be infected by E. multilocaris in some parts of Southern Belgium. The first local Belgian human AE cases were described in the early 2000's. Aim: The aim of this study was to report the experience of a tertiary university hospital of Southern Belgium with AE management. Methods: The authors retrospectively collected data from the parasitology laboratory (serologies), the hospital pharmacy in charge of supplying albendazole, and by searching through patient’s files with medico-economic information service of a tertiary university hospital. The medical files were retrospectively reviewed. Results: Twenty-one cases (66% male) of local AE have been recorded from 1999 to 2016. All patients were Belgian citizens with more than 30 years of life in Southern Belgium (Liege province: 10 cases (47.4%), Luxembourg province: 8 cases (36.8%), Namur Province: 3 cases (15.8 %)). Mean age of diagnosis was 66 years (ranges: (35-85y). Eighteen patients had hepatic involvement: 14 underwent surgical resection and 5 had unresectable liver lesions and underwent albendazole palliative therapy until death. During the same period, the faculty of veterinary medicine observed an increased rate of lethal hepatic AE in dogs, another indication of high AE incidence. Conclusions: AE appears to be spreading in Belgium and has actually an uneven geographical distribution with endemicity in areas of Southern and Eastern Belgium. However, it is probable that local AE cases will be diagnosed in the whole country, considering that there is no reason that infected foxes remain in Southern Belgium and also the fact that some people from Northern Belgium might spend long period in Southern Belgium, with or without their dogs. The liver is the most frequently involved organ and the only cure can be achieved by complete R0 resection of all AE lesions. In reaction to this experience, the authors created a multidisciplinary group for AE diagnosis and management, including hepatologists, infectiologists, microbiologists, pathologists, radiologists, nuclear medicine specialists, surgeons and veterinarians. The authorities should be aware of this medical issue and should facilitate the access to Albendazole for AE patients. A complete national survey should be encouraged, and BASL might have an important role in this study. [less ▲]

BACKGROUND AND STUDY AIMS: Anti-TNF monoclonal antibodies are a cornerstone in the treatment of Crohn's disease. Prospective data on switching from the subcutaneous and human adalimumab (ADM) to the intravenous and chimeric infliximab (IFX) are scarce. PATIENTS AND METHODS: In this prospective, observational, multicentre cohort study we included 21 patients with loss of response to ADM despite at least 4 consecutive weekly injections. Clinical response (CDAI drop>/=70 points) and remission (CDAI</=150) were assessed after switching from ADM to IFX after 10 weeks, 6 and 12 months. Predictive factors of response/remission, the need for therapy intensification, discontinuation and safety were investigated. RESULTS: Short-term response and remission (10 weeks) were seen in 57% and 48% respectively. Mid- and long-term clinical response and remission were achieved in 40% and 25% after 6 months and in 45% and 20% after 12 months respectively. At 12 months, 81% still were on IFX. IFX therapy intensification was needed in half of the patients at 6 months and three quarter of patients at 12 months. Undetectable ADM trough levels (despite weekly injections) were a predictive factor for short-term response and remission to IFX. About half of the patients with response at week 10 maintained response at 6 and 12 months. CONCLUSIONS: Switching from ADM to IFX can be efficacious in patients with loss of response, in particular in case of undetectable ADM trough levels. The majority of patients however will need IFX therapy intensification during their first year of treatment. [less ▲]
