Hepatitis C virus micro-elimination in vulnerable populations before and during a global pandemic.

OBJECTIVE: to analyze a hepatitis C virus (HCV) microelimination strategy targeting vulnerable populations and the influence of the pandemic on its maintenance and outcomes. METHODS: in 2018, the Hepatology Unit implemented an HCV microelimination strategy for patients attending drug addiction care centers and Psychiatry Units such as the Alcoholism Treatment Unit. These centers reported suspected or confirmed cases of HCV infection directly to the hepatologists, who, after reviewing the clinical records, cite those patients if necessary. RESULTS: from June 2018 to February 2020, hepatologists were consulted on 37 anti-HCV positive patients, 31 of them were from Drug Addiction Care Centers, 5 from the Alcoholism Disorders Unit and 1 from the Department of Psychiatry. Fibrosis stage: F0-F1, 18 (50%); F2, 9 (25%); F3, 2 (4.2%); F4, 8 (20.8%). Female sex, 6 (16.7%). Required attending: Yes, 27 (73%). 25 (92.6%) went. Outpatient consultation: 10 (27%). Required treatment: 19 (51.3%). Sustained virological response: 19 (100%). Fibrosis stage of treated patients: F0-F1, 13 (68%); F2, 2 (11%); F3, 1 (5%); F4, 3 (16%). Patients from the Psychiatry Department during 2021: 11. 9 (82%) do not need to attend; 2 (18%): their situation is unknown. CONCLUSIONS: sustained communication with centers that care for populations at risk of active HCV infection is needed to detect cases, increase adherence to treatment, and rescue patients who require screening for hepatocarcinoma.

Predictive factors for post-ERCP bleeding. Influence of direct oral anticoagulants.

INTRODUCTION: there is a rising number of patients receiving antiplatelet and anticoagulation therapy who require endoscopic retrograde cholangiopancreatography (ERCP), probably due to the increased morbidity of older patients. Considering the increasing use of direct oral anticoagulants (DOACs), this study aimed to determine the influence of these factors on the possibility of hemorrhage after ERCP in our center. MATERIAL AND METHODS: data were collected from all the examinations carried out in 2017 and 2018, which included 797 examinations on 588 patients. Collected data included personal history of the patients, results of the test and follow-up. RESULTS: the percentage of post-ERCP bleeding was 4.6 % (n = 37). With regard to the severity, the bleeding was mild in 21.6 % (n = 8) of the cases, moderate in 59.5 % (n = 22) and severe in 18.9 % (n = 7). Previous cardiopathy antiplatelet therapy, anticoagulation therapy, treatment with DOACs, having a pancreatic stent and lithiasis removal doubled the risk of bleeding after ERCP. Having a sphincterotomy increased the risk by over five-fold. CONCLUSION: according to the multivariate analysis, a statistically significant increase of bleeding among patients treated with DOACs was observed compared to patients who received anticoagulation with acenocoumarol or low-molecular-weight heparins (LMWH).

Antecedentes: el síndrome de intestino irritable tipo estreñimiento (SII-E) es una patología prevalente, compleja y multifactorial que representa un desafío tanto desde el punto de vista diagnóstico como terapéutico. Objetivo: evaluar la efectividad, seguridad y satisfacción de linaclotida en pacientes con SII-E. Métodos: estudio prospectivo, unicéntrico y observacional realizado en pacientes con diagnóstico de SII-E. Los pacientes recibieron tratamiento con linaclotida (Constella(r), Allergan Inc., Irvine, CA), 290 microgramos/24 horas, una cápsula 30 minutos antes del desayuno. La variable primaria de efectividad fue el número de deposiciones por semana. Las variables secundarias incluían el grado de satisfacción y el registro de la frecuencia e intensidad de los síntomas (dolor e hinchazón), medidos mediante una escala visual analógica (EVA) de once niveles (0-10), y recogidas mediante un diario que se entregó al paciente. Resultados: treinta pacientes, todas mujeres, fueron incluidas consecutivamente. La mediana del tiempo de seguimiento fue de 18 meses. La media (deviación estándar [DE]) de deposiciones por semana aumentó desde 0,9 (0,6) al inicio del estudio hasta 4,7 (3,7) al final del mismo (p < 0,0001). Resultados similares fueron observados con el dolor (5,7 [2,3] frente a 3,1 [2,8] al inicio y al final del estudio, respectivamente, p < 0,0001) y con la hinchazón (6,8 [1,6] frente a 2,9 [2,5] al inicio y final del estudio, respectivamente, p < 0,0001). El grado medio (DE) de satisfacción al final del estudio fue 6,7 (3,0). Conclusiones: el tratamiento con linaclotida en pacientes con SII-E en el entorno de la práctica clínica se ha mostrado eficaz y seguro a largo plazo

Background: constipation-predominant irritable bowel syndrome (C-IBS) is a prevalent, complex and multifactorial disorder that represents a challenge in terms of diagnosis and therapeutic management. Objective: to evaluate the effectiveness, safety and treatment satisfaction of linaclotide in C-IBS patients. Methods: prospective, single-center and observational study conducted in patients diagnosed with C-IBS. The patients were treated with linaclotide (Constella(r), Allergan Inc., Irvine, CA), once-daily via an oral capsule of 290-µg, 30 minutes before breakfast. The primary effectiveness endpoint was the number of bowel movements per week. The secondary endpoints included treatment satisfaction and changes from baseline in frequency and severity of symptoms (abdominal pain and bloating). This was assessed via an 11-point visual analog scale (VAS) reported by the patients in a daily register. Results: thirty female patients were consecutively included. The median follow-up time was 18 months. The mean (standard deviation [SD]) number of weekly bowel movements significantly increased from 0.9 (0.6) at baseline to 4.7 (3.9) at the end of follow-up, p < 0.0001. Abdominal pain significantly decreased from 5.7 (2.3) at baseline to 3.1 (2.8) at the end of the follow-up period, p < 0.0001. Similarly, bloating significantly decreased from 6.8 (1.6) to 2.9 (2.5) at the beginning and end of the treatment period, respectively, p < 0.0001. The mean (SD) degree of satisfaction at the end of the study was 6.7 (3.0). Conclusions: long-term linaclotide treatment in patients with C-IBS is effective and safe in the clinical setting

Prognostic factors for recurrence of gastrointestinal bleeding due to Dieulafoy's lesion.

AIM: To analyze the effectiveness of the endoscopic therapy and to identify prognostic factors for recurrent bleeding. METHODS: Retrospective study of patients with gastrointestinal bleeding secondary to Dieulafoy's lesion (DL) from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastrointestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding. We included cases in which endoscopy described a lesion compatible with Dieulafoy. We excluded patients who had potentially bleeding lesions such as angiodysplasia in other areas or had undergone other gastrointestinal endoscopic procedures. RESULTS: Twenty-nine patients with DL were identified. Most of them were men with an average age of 71.5 years. Fifty-five percent of the patients received antiaggregatory or anticoagulant therapy. The most common location for DL was the stomach (51.7%). The main type of bleeding was oozing in 65.5% of cases. In 27.6% of cases, there was arterial (spurting) bleeding, and 6.9% of the patients presented with an adherent clot. A single endoscopic treatment was applied to nine patients (31%); eight of them with adrenaline and one with argon, while 69% of the patients received combined treatment. Six patients (20.7%) presented with recurrent bleeding at a median of 4 d after endoscopy (interquartile range = 97.75). Within these six patients, the new endoscopic treatment obtained a therapeutic success of 100%. The presence of arterial bleeding at endoscopy was associated with a higher recurrence rate for bleeding (50% vs 33.3% for other type of bleeding) [P = 0.024, odds ratio (OR) = 8.5, 95% CI = 1.13-63.87]. The use of combined endoscopic treatment prevented the recurrence of bleeding (10% vs 44.4% of single treatment) (P = 0.034, OR = 0.14, 95% CI = 0.19-0.99). CONCLUSION: Endoscopic treatment of DL is safe and effective. Adrenaline monotherapy and arterial (spurting) bleeding are associated with a high rate of bleeding recurrence.

Endoscopic evaluation and histological findings in graft-versus-host disease.

BACKGROUND: the gastrointestinal (GI) tract is the major target site of the graft-versus-host disease (GVHD). Diagnosis is based on endoscopic and histological findings. MATERIAL AND METHODS: we performed a retrospective study from January 1st, 1990 to December 31st, 2008 on 338 upper gastrointestinal endoscopies (gastroscopies) performed to 197 patients that underwent an allogeneic transplant with clinical suspicion of GI-GVHD. RESULTS: endoscopic findings to the diagnosis of GVHD have a sensitivity (S) of 34%, specificity levels (SP) of 65%, a positive predictive value (PPV) of 73% and a negative predictive value (NPV) of 48%. The histological study of the endoscopic biopsies has a global sensibility of 85.6% SP = 34.6% PPV = 64.2% and NPV = 63.7%. Histological grade was correlated with the clinical grade of acute GVHD (p = 0.018). CONCLUSION: upper gastrointestinal endoscopy is useful for the diagnosis of GVHD, as it allows biopsies that can ultimately lead to the diagnosis, but with limited accuracy because the histological findings have low sensitivity and specificity, while the endoscopic findings are generally nonspecific.

Evaluación endoscópica y hallazgos histológicos en la enfermedad de injerto contra huésped / Endoscopic evaluation and histological findings in graft-versus-host disease

Introducción: el tracto gastrointestinal es la diana principal de afectación en la enfermedad de injerto contra huésped (EICH). Su diagnóstico se basa en los hallazgos endoscópicos e histológicos. Material y métodos: hemos realizado un estudio retrospectivo, desde el 1 de enero de 1990 hasta el 30 de diciembre de 2008, de 338 endoscopias digestivas altas realizadas a 197 pacientes sometidos a trasplante alogénico de células hematopoyéticas con sospecha de EICH gastrointestinal. Resultados: los hallazgos endoscópicos tienen una sensibilidad (S) del 34%, especificidad (E) del 65%, valor predictivo positivo (VPP) del 73% y valor predictivo negativo (VPN) del 48% para el diagnóstico de EICH. El estudio histológico de las biopsias tiene una S del 85,6%, E del 34,6%, VPP del 64,2% y VPN del 63,7%. El grado histológico se correlacionó con el grado clínico en la EICH aguda (p = 0,0018). Conclusión: la endoscopia digestiva alta es útil para el diagnóstico de EICH, ya que permite la toma de biopsias que finalmente pueden llevar al diagnóstico, pero con una rentabilidad limitada ya que los hallazgos histológicos tienen una sensibilidad y especificidad bajas, mientras que los endoscópicos son generalmente inespecíficos(AU)

[Autoimmune enteropathy in an adult patient]. / Enteropatía autoinmune en un paciente adulto.

Autoimmune enteropathy (AIE) is an infrequent cause of malabsorption that is usually associated with the presence of circulating autoantibodies and a predisposition to autoimmune disorders. This disease is more frequent in children. The diagnosis of this disorder is based on five criteria: chronic diarrhea (>6 weeks), malabsorption, specific histological findings, exclusion of similar disorders, and the presence of specific antibodies such as anti-enterocyte and anti-goblet cell antibodies. We present the case of a 63-year-old patient with chronic diarrhea, weight loss and significant deterioration of nutritional status.

[Emphysematous pancreatitis: Conservative or surgical treatment?]. / Pancreatitis enfisematosa. ¿Tratamiento conservador o quirúrgico?

Emphysematous pancreatitis is a severe and rare complication of acute pancreatitis. This entity is diagnosed on clinical grounds and on the basis of the radiologic finding of gas in the retroperitoneum. Infected pancreatic necrosis is potentially lethal, with mortality rates of more than 35%. Surgery is associated with significant morbidity and mortality in these critically ill patients. Endoscopic ultrasonography techniques, laparoscopic surgery and percutaneous drainage have the potential to offer a safe and effective alternative treatment modality. However, the precise role of these procedures requires further investigation. The treatment of these patients should be individualized, dynamic and multidisciplinary. We present two cases of emphysematous pancreatitis with distinct therapeutic management.

Pancreatitis enfisematosa. ¿Tratamiento conservador o quirúrgico? / Emphysematous pancreatitis: Conservative or surgical treatment?

La pancreatitis enfisematosa (PE) es una complicación grave y rara de la pancreatitis aguda. El diagnóstico se basa en los datos clínicos y en el hallazgo radiológico de gas en el retroperitoneo. La necrosis pancreática infectada es potencialmente letal, con una tasa de mortalidad superior al 35%. La cirugía en estos pacientes asocia una alta morbimortalidad. La ultrasonografía endoscópica, el tratamiento quirúrgico laparoscópico y el drenaje percutáneo ofrecen una modalidad de tratamiento alternativo a la cirugía, seguro y eficaz. Sin embargo, se requieren más estudios para definir el lugar que ocupan estas técnicas en el tratamiento de estos pacientes, que debe ser individualizado, dinámico y multidisciplinario.
