RESUMEN

BACKGROUND: Undiagnosed cases of hepatitis C virus (HCV) infection result in significant morbidity and mortality, further transmission, and increased public health costs. Testing in emergency departments (EDs) is an opportunity to expand HCV screening. The goal of this project was to increase the proportion of eligible patients screened for HCV in urban areas. METHODS: An opportunistic automated HCV screening program was implemented in the EDs of 4 public hospitals in Spain and Portugal at different periods between 2018 and 2023. HCV prevalence was prospectively evaluated, and single-step or reflex testing was used for confirmation in the same sample. RESULTS: More than 90% of the population eligible for testing were screened in the participating centers. We found HCV antibody seroprevalence rates ranging from 0.6 to 3.9%, with between 19 and 53% of viremic individuals. CONCLUSIONS: Opportunistic HCV screening in EDs is feasible, does not disrupt ED activities, is highly effective in increasing diagnosis, and contributes to WHO's HCV elimination goals.

RESUMEN

Background: Around 57,000 people in Spain and Portugal currently living with HIV or chronic hepatitis C are unaware of their infection. The COVID-19 pandemic severely disrupted screening efforts for these infections. We designed an intervention to increase and sustain opportunistic blood-borne virus (BBV) screening and linkage to care (SLTC) by implementing the TEST model. Methods: The Plan Do Study Act (PDSA) method of quality improvement (QI) was implemented in 8 healthcare organizations (HCOs), including four hospitals, two clusters of community health centers, and two community-based organizations (CBOs). Baseline assessment included a review of BBV SLTC practices, testing volume, and results 12 months before the intervention. Changes in BBV testing rates over time were measured before, during, and after the COVID-19 lockdowns in 2020. A mixed ANOVA model was used to analyze the possible effect on testing volumes among HCOs over the three study periods. Intervention: BBV testing was integrated into normal clinical flow in all HCOs using existing clinical infrastructure and staff. Electronic health record (EHR) systems were modified whenever possible to streamline screening processes, implement systemic institutional policy changes, and promote QI. Results: Two years after the launch of the intervention in screening practices, testing volumes increased by 116%, with formal healthcare settings recording larger increases than CBOs. The start of the COVID-19 lockdowns was accompanied by a global 60% decrease in testing in all HCOs. Screening emergency department patients or using EHR systems to automate screening showed the highest resilience and lowest reduction in testing. HCOs recovered 77% of their testing volume once the lockdowns were lifted, with CBOs making the fullest recovery. Globally, enhanced screening techniques enabled HCOs to diagnose a total of 1,860 individuals over the research period. Conclusions: Implementation of the TEST model enabled HCOs to increase and sustain BBV screening, even during COVID-19 lockdowns. Although improvement in screening was noted in all HCOs, additional work is needed to develop strong patient linkage to care models in challenging times, such as global pandemics.

RESUMEN

The authors describe a case of a 76-year-old male with a medical history of Merkel cell carcinoma (MCC) of the right lower eyelid. He was admitted to the emergency department due to abdominal pain in the right hypochondrium, nauseas, asthenia, and choluria with 3 days of evolution. Biochemical liver workup revealed a cytocholestase pattern as well as a prolonged prothrombin time. After admission, the patient developed hepatic encephalopathy, and a clinical and analytical worsening was observed. Abdominal ultrasound showed a reduction in the caliber of the hepatic veins, in apparent relation to a parenchymal compression. Liver biopsy was performed and showed an extensive infiltration of the hepatic parenchyma by a solid neoplasm, which, upon immunohistochemical study, was compatible with a diffuse metastization of a MCC. We report this clinical case due to its rarity of presentation and to show the important role of liver biopsy in cases of acute hepatitis.


Os autores descrevem o caso de um homem de 76 anos, com carcinoma de células de Merkel (CCM) da pálpebra direita, admitido no Serviço de Urgência por dor abdominal no hipocôndrio direito, náuseas, astenia e colúria com 3 dias de evolução. Analiticamente, apresentava um padrão citocolestático e coagulopatia com prolongamento do tempo de protrombina. Durante o internamento, desenvolveu encefalopatia hepática, com agravamento clínico e analítico. Ecograficamente, verificou-se redução do calibre das veias heapticas, em aparente relação com compressão parenquimatosa. Foi realizada biópsia hepática que relevou infiltração extensa do parênquima hepático por uma neoplasia sólida compatível, imunohis-toquimicamente, com metastização pelo CCM. Os autores reportam este caso clínico devido à raridade da sua apresentado, bem como para salientar o papel da biópsia hepática na abordagem dos casos de hepatite aguda.

RESUMEN

Background and study aims Previous studies have suggested a high prevalence of musculoskeletal injuries (MI) in endoscopists. Little evidence has come from European countries. Our main aim was to evaluate the prevalence, type, and impact of MI among Portuguese endoscopists. We also sought to identify risk factors for the development, severity and number of endoscopy-related MI. Material and methods A 48-question electronic survey was developed by a multidisciplinary group. The electronic survey was sent to all members of Portuguese Society of Gastroenterology (n = 705) during May 2019. Study data were collected and managed using REDCap electronic data capture tools hosted at SPG - CEREGA. Results The survey was completed by 171 endoscopists (response rate of 24.3 %), 55.0 % female with a median age of 36 years (range 26-78). The prevalence of at least one MI related to endoscopy was 69.6 % (n = 119), the most frequent being neck pain (30.4 %) and thumb pain (29.2 %). The median time for MI development was 6 years (range 2 months-30 years). Severe pain was reported by 19.3 %. Change in endoscopic technique was undertaken by 61.3 % and reduction in endoscopic caseload was undertaken by 22.7 %. Missing work was reported by 10.1 %, with the median time off from work being 30 days (range 1-90). Female gender and ≥ 15 years in practice were independently associated with MI and severe pain. Years in practice, weekly-time performing endoscopy, and gender were significant predictors of the number of MI. Conclusions Prevalence of MI was significant among Portuguese endoscopists and had a relevant impact on regular and professional activities.

RESUMEN

Chronic pancreatitis (CP) is a complex disease that should be treated by experienced teams of gastroenterologists, radiologists, surgeons, and nutritionists in a multidisciplinary environment. Medical treatment includes lifestyle modification, nutrition, exocrine and endocrine pancreatic insufficiency correction, and pain management. Up to 60% of patients will ultimately require some type of endoscopic or surgical intervention for treatment. However, regardless of the modality, they are often ineffective unless smoking and alcohol cessation is achieved. Surgery retains a major role in the treatment of CP patients with intractable chronic pain or suspected pancreatic mass. For other complications like biliary or gastroduodenal obstruction, pseudocyst drainage can be performed endoscopically. The recommendations for CP were developed by Clube Português do Pâncreas (CPP), based on literature review to answer predefined topics, subsequently discussed and approved by all members of CPP. Recommendations are separated in two parts: "chronic pancreatitis etiology, natural history, and diagnosis," and "chronic pancreatitis medical, endoscopic, and surgical treatment." This abstract pertains to part II.

RESUMEN

Chronic pancreatitis (CP) is a heterogeneous disease, with different causes and often a long delay between onset and full classic presentation. Clinical presentation depends on the stage of the disease. In earlier stages, recurrent episodes of acute pancreatitis are the major signs dominating clinical presentation. As the inflammatory process goes on, less acute episodes occur, and pain adopts different aspects or may even disappear. After 10-15 years from onset, functional insufficiency occurs. Then, a classic presentation with pain and pancreatic exocrine and endocrine insufficiency appears. Diagnosis remains challenging in the early stages of the disease, as its initial presentation is usually ill-defined and overlaps with other digestive disorders. Computed tomography and magnetic resonance cholangiopancreatography should be the first choice in patients with suspected CP. If the results are normal or equivocal but still there is a high suspicion of CP, the next option should be endoscopic ultrasound. Endoscopic retrograde cholangiopancreatography is mainly a therapeutic technique, and for the diagnostic purpose should only be used when all other imaging modalities and pancreatic function tests have been exhausted. Indirect tests are used to quantify the degree of insufficiency in already-established late CP. Recommendations on CP were developed by Clube Português do Pâncreas (CPP), based on literature review to answer predefined topics, subsequently discussed and approved by all members of CPP. Recommendations are separated in two parts: "chronic pancreatitis etiology, natural history, and diagnosis," and "chronic pancreatitis medical, endoscopic, and surgical treatment." This abstract pertains to part I.


A pancreatite crónica (PC) é uma doença heterogénea, com diferentes etiologias, muitas vezes, com um longo período entre o início de sintomatologia e a apresentação clínica clássica. A clínica depende do estadio da doença, sendo que nos estadios iniciais, predominam episódios recorrentes de pancreatite aguda; com a progressão da doença, os episódios agudos tornam-se menos frequentes, e a dor adota padrões diferentes, podendo inclusive desaparecer; a insuficiência funcional desenvolve-se 10 a 15 anos após o início, assumindo-se então, a apresentação clássica com dor, insuficiência pancreática exócrina e endócrina. O diagnóstico pode ser desafiador nos estadios iniciais da doença, já que a apresentação inicial é geralmente mal definida e se sobrepõe a outros patologias gastrointestinais. A TAC e CPRM devem ser os primeiros métodos de imagem em doentes com suspeita de PC. Se os resultados forem normais ou ambíguos, a próxima opção deve ser a ecoendoscopia. A CPRE é uma técnica principalmente terapêutica, sendo que para fins de diagnóstico, deve ser reservada para quando todas os outros exames de imagem/testes de função pancreática forem inconclusivos. Testes indiretos de função pancreática devem ser usados para quantificação do grau de insuficiência pancreática em doentes com PC já estabelecida. As recomendações sobre PC foram desenvolvidas pelo Clube Português do Pâncreas (CPP), com base numa revisão da literatura para responder a questões predefinidas, posteriormente discutidos e aprovados por todos os membros do CPP. As recomendações encontram-se separadas em duas partes: "etiologia da pancreatite crónica, história natural e diagnóstico" e "tratamento médico, endoscópico e cirúrgico da pancreatite crónica." Este resumo corresponde à parte I.

RESUMEN

Hepatosplenic T-cell lymphoma (HSTCL) is an extremely rare and aggressive form of non-Hodgkin lymphoma associated with poor response to treatment and high mortality. There is an increased incidence among patients with inflammatory bowel disease, especially young male patients under 35 years old and on combination therapy (thiopurine and anti-TNF-α). We describe a case of HSTCL in a young male patient with stenosing ileal Crohn's disease on azathioprine monotherapy for 4.8 years admitted to our hospital with intra- abdominal sepsis. Despite chemotherapy, the patient eventually died 1 month after the diagnosis. Through a literature review, we identified 18 additional cases of HSTCL in Crohn's disease patients that had only been treated with thiopurine monotherapy. The authors intend to highlight the rarity of this diagnosis especially with azathioprine monotherapy and the diagnostic challenge in a case that presented with intra-abdominal sepsis.


O linfoma de células T hepatoesplénico é um tipo raro e agressivo de linfoma não Hodgkin associado a fraca reposta à terapêutica e elevada mortalidade. A sua incidência está aumentada em doentes com doença inflamatória intestinal, particularmente jovens com menos de 35 anos, do sexo masculino e em terapêutica combinada com tiopurinas e inibidores TNF-α. Apresentamos o caso de um linfoma T hepatoesplénico num homem jovem com doença de Crohn ileal estenosante sob monoterapia com azatioprina há 4,8 anos, admitido no nosso hospital num contexto de sépsis de ponto de partida intraabdominal. Apesar da quimioterapia o doente acabou por falecer 1 mês após o diagnóstico. Numa revisão da literatura, os autores identificaram 18 casos adicionais de linfoma T hepatosplénico em doentes com doença de Crohn tratados apenas com tiopurinas em monoterapia. Os autores pretendem destacar a raridade do diagnóstico, especialmente no contexto de azatioprina em monoterapia e o desafio diagnóstico num caso que se apresentou com sépsis intra-abdominal.

RESUMEN

Esophageal and gastroduodenal necrosis are rare conditions with poor prognosis. We describe a case that was diagnosed with upper endoscopy in the setting of severe septic shock. To our knowledge, this is the first case in which esophageal and gastroduodenal necrosis occurred simultaneously in this setting. We discuss the pathophysiology, diagnostic approach, and treatment options of this rare entity.

RESUMEN

We report the case of a 48-year-old, leukodermic female diagnosed with ulcerative proctitis for 4 years and latent tuberculosis. She was allergic to salicylates and had a minor allergic reaction to infliximab (rash, vertigo, and headache). Thereafter, she started azathioprine (2.5 mg/kg/day). She maintained intravenous infliximab, together with prophylaxis with clemastine and hydrocortisone, due to the steroid-dependent proctitis. The therapy was continued every 8 weeks with anti-tumor necrosis factor for about 3 years. The analytical evaluation when she was diagnosed with ulcerative proctitis (February 2011) showed negative antinuclear antibodies (ANA), double-stranded-DNA antibodies (anti-dsDNA), antineutrophil cytoplasmic antibodies and anti-Saccharomyces cerevisiae antibodies, and a positive outer membrane protein antibody. About 2 years and 6 months after starting infliximab (November 2013), the patient complained of inflammatory symmetrical polyarthralgia (knee, shoulder, elbow, and wrist) without synovitis, which started every week before the administration of infliximab. Resolution of symptoms was observed after each infliximab infusion. In July 2014, the autoantibody re-evaluation showed positive ANA with a homogeneous pattern with a titer of 1:640, weak positive anti-dsDNA (30.2), and positive anti-histone with C3 decreased (80.3). She was then diagnosed with lupus induced by infliximab and initiated hydroxychloroquine 400 mg. Infliximab was suspended. On re-evaluation, the erythrocyte sedimentation rate was 25 mm/h (1st hour), C-reactive protein 0.5 mg/dL (previously erythrocyte sedimentation rate 15 mm/h and C-reactive protein 1.2 mg/dL), and endoscopically, the mucosa was scarred, with some atrophy and scarce mucus in the lower rectum. About 10 months after discontinuation of infliximab, repeated autoantibodies proved all negative, keeping only low C3 (87). The patient also reported complete resolution of the arthralgia.

RESUMEN

BACKGROUND: For many years, ERCP was avoided in pregnancy given the concerns regarding the adverse effects that, with special focus on radiation, could occur in the developing fetus. However, the postponement or rejection of ERCP in pregnant women, may lead to a higher risk for mother and fetus, especially when the indication is unequivocal, namely cholangitis, biliary pancreatitis and symptomatic choledocholithiasis. SUMMARY AND KEY MESSAGES: This review aims to summarize the scarce literature on the subject in order to plan ERCP in pregnancy with the highest safety. The use of techniques that reduce radiation and increase the protection of pregnant women allow radiation levels far below the safety limits. We also discuss the various alternatives of ERCP without radiation. EUS can eliminate the need for ERCP with doubtful choledocholithiasis and plan the best approach in those with previous evidence. The possibility of performing "ERCP" with a linear echoendoscope uniquely under ultrasound control has been described. Conversely, the two-step strategy (initial sphincterotomy with stent placement without fluoroscopy and after delivery, ERCP with lithiasis extraction) proved to be safe obviating fluoroscopy. In conclusion, ERCP can be performed in pregnancy safely and effectively with minimal radiation or even no-radiation at all.

RESUMEN

The posterior reversible encephalopathy syndrome is a neurological syndrome characterized by headache, confusion, visual disturbances and seizures associated with identifiable areas of cerebral edema on imaging studies. The authors report the case of a man, 33 years-old, leukodermic with a history of chronic alcohol and tobacco consumption, who is admitted to the emergency department for epigastric pain radiating to the back and vomiting with about six hours of evolution and an intense holocranial headache for two hours. His physical examination was remarkable for a blood pressure of 190/100 mmHg and tenderness in epigastrium. His analytical results revealed emphasis on amylase 193 U/L and lipase 934 U/L. During the observation in the emergency department,he presented a generalized tonic-clonic seizure. Abdominal ultrasonography was performed and suggestive of pancreatitis withoutgallstones signals. Head computed tomography showed subarachnoid haemorrhage and a small right frontal cortical haemorrhage. The brain magnetic resonance imaging done one week after admission showed areas of a bilateral and symmetrical T2 / FLAIR hyperintensities in the subcortical white matter of the parietal and superior frontal regions, suggesting a diagnosis of posterior reversible encephalopathy syndrome. Abdominal computed tomography (10 days after admission) demonstrated a thickened pancreas in connection with inflammation and two small hypodense foci in the anterior part of the pancreas body, translating small foci of necrosis. The investigation of a thrombophilic defect revealed a heterozygous G20210A prothrombin gene mutation. The patient was discharged without neurological sequelae and asymptomatic. The follow-up brain magnetic resonance imaging confirmed the reversal of the lesions, confirming the diagnosis.


A síndrome de enfalopatia posterior reversível é uma síndrome neurológica caracterizada por cefaleias, confusão, alterações visuais e convulsões associada a áreas de edema cerebral identificável em exames de neuroimagem. Os autores relatam o caso de um homem, 33 anos, leucodérmico, com história de alcoolismo e tabagismo crónico, que recorre ao serviço de urgência por epigastralgia em cinturão e vómitos com cerca de seis horas de evolução e cefaleia holocraneana intensa há duas horas. Ao exame objectivo, apresentava tensão arterial de 190/100 mmHg e empastamento no epigastro. Analiticamente, amilase 193 U/L e lipase 934 U/L. Durante a observação no serviço de urgência, apresentou uma crise tónico-clónica generalizada. A ecografia abdominal realizada foi sugestiva de pancreatite, sem sinais de litíase biliar. A tomografia computorizada crânio-encefálica demonstrou hemorragia subaracnoideia e pequena hemorragia cortical frontal direita. A ressonância magnética nuclear crânio-encefálica realizada uma semana após a admissão revelou áreas de hipersinal T2/FLAIR bilaterais e simétricas na substância branca subcortical das regiões parietais e frontais superiores, sugerindo o diagnóstico de síndrome de enfalopatia posterior reversível. Na tomografia computorizada abdominal (10 dias após a admissão) visualizou-se pâncreas espessado, em relação com processo inflamatório e dois pequenos focos hipodensos na parte anterior do corpo, traduzindo pequenos focos de necrose. A investigação de defeitos trombofílicos revelou uma mutação do gene G20210A da protrombina em heterozigotia. O doente teve alta sem sequelas neurológicas, e assintomático. A ressonância magnética nuclear crânio-encefálica de controlo confirmou a reversão das lesões, confirmando o diagnóstico.
