Inflammatory Bowel Disease Patients' Perspectives during COVID-19 Pandemic: Results from a Portuguese Survey.

INTRODUCTION: Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients' perspectives and fears. We aimed to evaluate Portuguese IBD patients' perspectives on the clinical management of their disease during the SARS-CoV-2 pandemic as well as the impact on their professional life. METHODS: An anonymous electronic survey was created using REDCap and was distributed by the Portuguese Association of Inflammatory Bowel Disease (APDI) between May and August 2020. Patients' perspectives on immunosuppressive therapy, disease management, interaction with gastroenterology departments, and the impact of the pandemic in their professional life were assessed. Patients' proposals to improve medical care were also evaluated. Descriptive analysis and logistic regression were performed. RESULTS: A total of 137 participants answered the survey (79.6% females, mean age 41.7 ± 12.1 years). Although having IBD and receiving treatment with immunosuppressors (thiopurines, steroids, or biologics) were considered promotors of anxiety, most patients (85.4%) agreed that disease remission was a priority and only a minority of patients interrupted their treatment during the pandemic. In multivariate analysis, active disease, biologic treatment, and use of corticosteroids in the last 3 months were perceived by the patients as high-risk features for increased risk of SARS-Cov-2 infection and more severe disease. Fifty-nine patients (44%) believed that their follow-up was influenced by the pandemic and only 58.8% felt that they had the opportunity to discuss their therapeutic options with their doctor. Sixty-three patients (46.0%) were working from home during the pandemic, although this decision was related to IBD and immunosuppressive therapy in only 36.5 and 39.7% of the cases, respectively. Areas where care could have been improved during the pandemic were identified by patients, namely enhancement of the communication with IBD professionals, conciliation of telemedicine with face-to-face appointments, and facilitation of the interaction between patients and employers. CONCLUSION: Most patients agreed that maintaining IBD remission is crucial, and only a minority of the patients stopped their treatment as per their own initiative. IBD status only had a small influence on patients' professional activity during the COVID-19 outbreak, with most changes being related to the pandemic itself.

Fecal Microbiota Transplant in a Patient Infected with Multidrug-Resistant Bacteria: A Case Report.

INTRODUCTION: There has been a growing interest in fecal microbiota transplantation (FMT) as a way to manipulate gut microbiota, with potential benefit in patients infected with multidrug-resistant (MDR) bacteria. CASE PRESENTATION: We present the case of an 87-year-old male with recurrent ascending cholangitis due to biliary atony and impaired biliary drainage after multiple biliary sphincterotomies and two papillary balloon dilations. In this context, a choledochoduodenostomy was performed, but the patient kept on having repeated episodes of acute cholangitis, resulting in multiple hospitalizations, every other week, with need of multiple broad-spectrum antibiotic courses, which led to bacteremias with MDR microorganisms. Several therapeutic strategies such as prophylactic antibiotics (including rifaximin), pre- and probiotics, prokinetics, and ursodeoxycholic acid were unsuccessfully attempted. After multidisciplinary case discussion, an FMT was proposed, with the aim of manipulating gut microbiota and decreasing MDR bacteremias. We first performed FMT via colonoscopy in September 2018, after which the patient still had 3 more hospitalizations for acute cholangitis, but isolated bacteria in blood cultures were resistant only to amoxicillin and clavulanic acid. Considering this apparent change in the microbial resistance profile, we performed a second FMT in January 2019 via the upper gastrointestinal route. During the next 4 months, the patient remained well. In April 2019, the patient relapsed again with three more episodes of cholangitis, for which we repeated the FMT via upper gastrointestinal endoscopy. No readmissions were observed during the next 4 months. All three FMTs were performed without complications. DISCUSSION AND CONCLUSION: FMT seems to be a safe procedure and was effective in decreasing hospital admissions and changing the profile of MDR bacteria previously isolated from blood cultures.

INTRODUÇÃO: Tem havido um crescente interesse no transplante de microbiota fecal (TMF) como forma de manipular a microbiota intestinal, com potencial benefício em doentes infetados com microorganismos resistentes aos antibióticos (MRA). CASO CLÍNICO: Apresentamos o caso de um homem de 87 anos de idade com colangite ascendente recorrente por atonia biliar e atraso na drenagem biliar após múltiplas esfincterotomias e duas esfincteroplastias com balão. Neste contexto, o doente foi submetido a uma coledocoduodenostomia, mantendo, no entanto, episódios recorrentes de colangite com elevada frequência (2 semanas), o que motivou hospitalizações múltiplas com necessidade de antibioterapia de largo-espectro, tendo como consequência bacteriémias por MRA. Várias estratégias terapêuticas, como antibioterapia profilática (incluindo rifaximina), pré e probióticos, procinéticos e ácido ursodesoxicólico, foram tentadas sem sucesso. Após discussão multidisciplinar do caso foi proposta a realização de um TMF, como forma de manipular a microbiota intestinal e diminuir as bacteriémias por MRA. Realizámos um TMF por via baixa (colonoscopia) em Setembro de 2018, após o qual o doente teve mais 3 hospitalizaçõesporcolangite, combacteriémiaa um microorganismo apenas resistente à amoxicilina e ácido clavulânico. Considerando a aparente mudança no perfil de resistência microbiana, realizamos um segundo TMF em Janeiro de 2019 por via alta (endoscopia), após o qual o doente permaneceu assintomático e sem novos internamentos durante 4 meses. Em Abril de 2019, o doente voltou a ter três episódios de bacteriémia com necessidade de internamento, pelo que repetimos a realização do TMF por via alta. O doente permaneceu sem novos internamentos durante 4 meses. Nenhum dos procedimentos teve complicações. DISCUSSÃO E CONCLUSÃO: O TMF parece ser um procedimento seguro e foi eficaz na redução de internamentos hospitalares e na mudança do perfil de resistência dos microorganismos isolados nas hemoculturas.

ARE CARIOGENIC BACTERIA THE MAJOR RISK FACTOR TO DENTAL CARIES IN PATIENTS WITH ULCERATIVE COLITIS?

BACKGROUND: High prevalence of dental caries in ulcerative colitis (UC) has been attributed to diet and changes in salivary environment. OBJECTIVE: We aimed to characterize the prevalence of dental caries, salivary flow rates, salivary buffering capacity and cariogenic bacteria counts of Mutans streptococci and Lactobacillus spp and to evaluate their relationship with drug therapy, disease activity and duration. METHODS: A cross-sectional study was performed with UC patients followed in a tertiary center. Participants were submitted to a questionnaire (including demographic data, oral hygiene, eating habits) and a clinical observation with assessment of plaque index and Decayed, Missing and Filled Teeth index. Unstimulated/stimulated saliva was collected. Medical records, disease activity (Partial Mayo Score) and disease duration were collected. Laboratory data included salivary flow rates, salivary buffering capacity (CRT® buffer) and cariogenic bacteria count (Mutans streptococci and Lactobacillus spp) in saliva using the CRT® bacteria test (results: high or low counts). RESULTS: Thirty UC patients were recruited. Oral hygiene routines were daily teeth brushing once or more (96.7%) and fluoride toothpaste (73.3%). Decayed, Missing and Filled Teeth index (mean 16.17±6.428) was not affected by the frequency of soft drinks, cakes, sweets and sugars between meals (P>0.2). Long-term disease showed a trend towards higher prevalence of caries (P=0.06). Most presented normal salivary flow rates, unstimulated (73.3%) and stimulated (60.0%), and high salivary buffering capacity (66.7%). Any association was found with age, gender, disease activity, disease duration and drug therapy. High Mutans streptococci and low Lactobacillus spp count were observed in 73.3% and 60% of patients, respectively. Patients with active disease (100%) and longer duration (88.9%) displayed higher Mutans streptococci count. CONCLUSION: The prevalence of dental caries observed in UC patients was significant and did not seem to be influenced by their eating habits. The high prevalence of Mutans streptococci count may be a major risk factor for dental caries and may be looked as part of the UC dysbiosis. Dental care of UC patients should be planned according with this microbiota variation.

RESUMO CONTEXTO: Uma elevada prevalência de cáries dentárias em doentes com retocolite ulcerativa (RCU) tem sido atribuída à dieta e alterações no ambiente salivar. OBJETIVO: Este estudo pretende caracterizar a prevalência de cáries dentárias, taxas de fluxo salivar, capacidade de tamponamento da saliva e contagem de bactérias cariogénicas, Streptococcus mutans e Lactobacillus spp e avaliar a sua relação com a terapêutica farmacológica e a atividade e duração da doença. MÉTODOS: Estudo transversal com doentes com RCU seguidos num centro terciário. Os participantes foram submetidos a um questionário (incluindo questões sobre dados sociodemográficos, higiene oral e hábitos alimentares), e a uma observação clínica com avaliação do índice de placa e índice Decayed, Missing and Filled Teeth. Amostras de saliva não estimulada e estimulada foram colhidas. Os registos clínicos, a atividade da doença (score parcial de Mayo) e a sua duração foram avaliados. Os dados laboratoriais incluíram taxas de fluxo salivar, capacidade de tamponamento da saliva (CRT® buffer) e a contagem de bactérias cariogénicas (Streptococcus mutans e Lactobacillus spp) utilizando o teste CRT® (resultado: contagem elevada ou reduzida). RESULTADOS: Foram recrutados 30 doentes com RCU. As rotinas de higiene oral incluíram a escovagem dos dentes uma ou mais vezes por dia (96,7%) e o uso de pasta com flúor (73,3%). O índice Decayed, Missing and Filled Teeth (média 16,17±6,428) não foi afetado pela frequência de ingestão de refrigerantes, bolos, doces e açucares entre as refeições (P>0,2). Doentes com doença de longa duração apresentaram uma tendência para maior prevalência de cáries dentárias (P=0,06). A maioria possuía taxas de fluxo salivar normais, quer de saliva estimulada (60%) quer de saliva não estimulada (73,3%), assim como taxas de tamponamento salivar elevadas (66,7%). Não foi encontrada associação entre estas características com a idade, género, atividade/duração da doença e tipo de terapêutica farmacológica. Contagens elevadas de Streptococcus mutans e reduzidas de Lactobacillus spp foram observadas em 73,3% e 60% dos doentes, respectivamente. Doentes com doença ativa e maior tempo de evolução apresentaram contagens superiores de Streptococcus mutans. CONCLUSÃO: A prevalência de cárie dentária observada em doentes com RCU foi significativa e não parece ser influenciada pelos hábitos alimentares. A prevalência aumentada de Streptococcus mutans foi o fator de risco maior para a cárie dentária e provavelmente constitui parte da conhecida disbiose oral associada à RCU. Os cuidados dentários a estes doentes deverão ter em consideração esta variação da microbiota.

Mid upper arm circumference and Powell-Tuck and Hennessy's equation correlate with body mass index and can be used sequentially in gastrostomy fed patients.

BACKGROUND & AIMS: Body Mass Index (BMI) is a simple and widespread method to assess undernutrition. However its use may be limited in bedridden patients. AIMS: 1) compare BMI, Mid Upper Arm Circumference (MUAC) and Powell-Tuck and Hennessy's regression equation for BMI (BMIPTH) in gastrostomy fed patients, 2) validate its correlation for sequential use and 3) select the best cut-off of MUAC and BMIPTH to predict risk of undernutrition. METHODS: Prospective study including adult patients who underwent endoscopic gastrostomy (PEG). BMI, MUAC and BMIPTH adjusted for sex and age were determined at the day of gastrostomy (0), first (1) and third (3) months of follow up. Correlations between BMI and MUAC and BMIPTH were calculated at all time-points using Spearman's test. MUAC's Area Under ROC (AUROC) to predict risk of undernutrition (BMI ≤ 18,5 kg/m2 in non-elderly (<65 years) and BMI ≤ 22,5 kg/m2 in elderly (≥65 years)) was calculated with DeLong method and Youden Index was used to select the best cut-off for this outcome. RESULTS: 405 PEG patients were included (69,9% males, median age 62,9 ± 15,3 years). Head and neck cancer and neurological disorders were the main indications for gastrostomy. BMI correlated moderately with BMIPTH0 (ρ = 0.646-0.694), MUAC0 (ρ = 0.669) and MUAC1 (ρ = 0.699). BMI correlated strongly with BMIPTH1 (ρ = 0.764-0.794), BMIPTH3 (ρ = 0.714-0.732) and MUAC3 (ρ = 0.725). MUAC and BMIPTH's accuracy was not significantly different to predict undernutrition neither in elderly (AUROC 0.835 ± 0.033 Vs. 0.836 ± 0.033 respectively, p = 0.319) nor in non-elderly patients (AUROC 0.857 ± 0.027 Vs. 0.888 ± 0.053 respectively, p = 0.256). MUAC <26 cm (positive predictive value (PPV) 83.5%) or BMIPTH <22 kg/m2 (PPV 83.5%) in elderly and MUAC <25 cm (PPV 90.7%) or BMIPTH <21 kg/m2 (PPV 91.7%) in non-elderly can accurately predict risk of undernutrition in PEG patients. CONCLUSIONS: MUAC and BMIPTH correlated with BMI not only at the day of PEG placement but also at the 1st and 3rd month of follow up and were equivalent to predict risk of undernutrition according to the new cut-offs defined for this population.

Pancreatoblastoma: an unusual diagnosis in an adult patient.

The authors describe a 31-year-old man admitted due to progressive weight loss, diarrhea and massive hepatomegaly. Laboratory data showed anemia (haemoglobin 11.7 g/dl), abnormal liver tests (total bilirubin 1.4 g/dl, aspartate aminotransferase 70 U/l, alanine aminotransferase 37 U/l and alkaline phosphatase 520 U/l). Abdominal ultrasound (US) displayed a large heterogeneous liver with a segment IV 25 mm nodule. Magnetic resonance revealed a 4 cm pancreatic tail mass and several liver nodules consistent with metastasis. The patient underwent an endoscopic ultrasound (EUS) with fine needle aspiration (FNA) from the pancreatic mass and liver metastasis with cytological evaluation consistent with a pancreatoblastoma, later confirmed through a percutaneous US-guided liver biopsy. During the inpatient period, liver function deteriorated and acute kidney injury developed. Severe progressive cachexia was observed. The patient was discharged on renal replacement therapy and palliative care. Death occurred 3 months after diagnosis. Pancreatoblastoma is an uncommon pancreatic malignant epithelial cancer of the pancreas, typically occurring in the paediatric population. Adult pancreatoblastoma is extremely rare, with about 40 cases reported in the literature and generally presenting a more aggressive biologic and clinical behaviour. Surgical resection is the treatment of choice, but most cases are detected in advanced stages. This case underlines the ability to establish a pancreatoblastoma cytology-based diagnosis with EUS-FNA, and confirms the associated poor outcome.

CLIF-C ACLF score is a better mortality predictor than MELD, MELD-Na and CTP in patients with Acute on chronic liver failure admitted to the ward.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is a frequent syndrome associated with high mortality. The aims of the present study are: a) comparing the Chronic Liver Failure Consortium (CLIF-C) ACLF Model for End-Stage Liver Disease (MELD), MELD Sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores for prediction of short/medium term mortality; b) identifying ACLF prevalence in patients admitted to the ward; and c) comparing mortality between non-ACLF/ACLF. METHODS: Retrospective cohort study of 177 patients admitted to the Gastroenterology ward for acute decompensation of cirrhosis. RESULTS: We included 132 males. Alcohol was the cirrhosis cause/co-factor in 79.7% of cases. Infection was present in 40.7%. At admission, 19.8% of patients presented ACLF and 7.9% developed it during hospitalization (overall prevalence was 27.7%). ACLF grade 1 was diagnosed in 55.1% of the ACLF patients; grade 2, in 42.8%, and grade 3, in 2.0%. Infection (p < 0.001) and hepatic encephalopathy (p = 0.004) were more prevalent and C-reactive protein and leukocyte counts were higher in ACLF patients. ACLF 28 and 90-day mortality was 45.8% and 60.4%, respectively. The CLIF-C ACLF score was significantly superior to CTP, MELD, MELD-Na in predicting 28-day (AUROC 0.799 ± 0.078, 95% CI 0.637-0.891) and 90-day mortality (AUROC 0.828 ± 0.063, 95% CI 0.705-0.952). CONCLUSION: ACLF is highly prevalent in the ward. The new CLIF scores identify high mortality cirrhotic patients admitted to the ward and are better than their predecessors to predict ACLF patients' short/medium term mortality.

Autoimmune pancreatitis and inflammatory bowel disease: Case series and review of the literature.

BACKGROUND: An association between autoimmune pancreatitis (AIP) and inflammatory bowel disease (IBD) has been documented, but its clinical significance remains unclear. AIMS: Characterize the particular phenotypes of IBD and AIP in patients with both diseases (IBD-AIP). METHODS: Retrospective study of patients with IBD-AIP followed at our IBD referral centre and literature search to identify previous reports of IBD-AIP patients. RESULTS: We found 5 cases of IBD-AIP in our records and 5 prior studies reporting 47 additional IBD-AIP patients. A combined analysis showed that most IBD-AIP patients were young males with ulcerative colitis, usually extensive, and that in all Crohn's disease cases, the colon was involved. IBD severity was heterogeneous across studies, ranging from mild disease to severe disease requiring colectomy. The most frequent type of AIP was idiopathic duct-centric pancreatitis (type 2) and it most often occurred after the diagnosis of IBD. AIP presentation and treatment were similar to those in the general population. CONCLUSIONS: AIP occurs rarely with IBD; in the other way around, up to 1/3 of AIP patients, especially type 2, may have concomitant IBD. IBD-AIP patients are usually males presenting extensive colitis. More data are needed on the impact of AIP, if any, in IBD course.

Pelvic inflammatory myofibroblastic tumor mimicking a rectal cancer.

We report a case of a 50-year-old woman who presented to the emergency department with large bowel obstruction and anemia. The initial imaging study suggested an inoperable rectal tumor with involvement of surrounding structures. In this paper we discuss the diagnostic work-up of this patient with a diagnosis of pelvic/perirectal inflammatory myofibroblastic tumor (IMT). IMT is a rare tumor with intermediate malignant potential that frequently mimics clinical and imaging features of malignancy. Additionally, to the best of our knowledge, this is the first case of a pelvic IMT that regressed without surgical excision.

Hepatic haemangiomatosis: multinodular liver in an asymptomatic elderly man.

A 66-year-old man, overweight and a heavy drinker, was sent to our clinic to investigate multiple liver nodules detected on ultrasound. The patient had no symptoms, and physical examination was unremarkable. Laboratory evaluation disclosed an isolated two-fold increase of γ-glutamyltransferase. The MRI revealed multiple millimetric hypervascular nodules suggestive of liver haemangiomatosis, though malignancy could not be ruled out. Liver biopsy was consistent with hepatic haemangiomatosis. We discuss the differential diagnosis and therapeutical approach of a patient with hepatic haemangiomatosis involving the entire liver without associated symptoms or liver dysfunction.
