RESUMEN

A 66-year-old female presented to our hospital with diffuse abdominal pain and diarrhea. An abdominal CT showed a splenic abscess of 9.9 x 6.1 x 6.5 cm. A conservative approach with US-guided percutaneous drainage and antibiotic treatment was performed successfully. Splenic abscess is a rare complication of Salmonella spp infection. In selected cases, percutaneous drainage can be performed safely with good efficacy.

RESUMEN

Objetivos La incidencia de la esofagitis eosinofílica (EEo) está aumentando en algunas regiones del mundo. Estudios retrospectivos han encontrado asociación inversa con la infección por Helicobacter pylori (H. pylori). Un estudio prospectivo reciente ha cuestionado esta relación. Por lo que buscamos evaluar esta relación en pacientes mexicanos. Pacientes y métodos Evaluamos pacientes adultos sin erradicación previa de la infección por H. pylori. Los casos se definieron por la presencia de síntomas esofágicos y > 15 eosinófilos/campo de alto poder (CAP) en biopsias de esófago. Los controles, por la presencia de < 15 eosinófilos/CAP. La infección por H. pylori se estableció por histología. Los pacientes fueron pareados por edad y género, asignando cuatro controles por caso. Resultados Se incluyeron 190 pacientes: 38 casos y 152 controles. Los casos tuvieron mayor frecuencia de atopia, disfagia, impactación alimentaria, eosinofilia periférica y anormalidades endoscópicas de EEo. La prevalencia de la infección por H. pylori fue de 63,6%. Los casos tuvieron prevalencia significativamente menor que los controles (36,8 vs. 70,4%, odds ratio (OR) 0,21, intervalo de confianza (IC) 95% 0,08-0,69, p = 0,001). Los pacientes atópicos tuvieron menor prevalencia en comparación con aquellos sin atopia: 13,1 vs. 50,5% (OR 0,20, IC 95% 0,06-0,69, p < 0,001), particularmente con rinitis alérgica y alergia alimentaria. Conclusiones Observamos una relación inversa entre la infección por H. pylori y EEo así como con atopia. Se necesitan estudios en modelos experimentales de EEo que clarifiquen el papel del H. pylori en esta interacción, así como estudios robustos que incluyan otros factores que puedan influir en esta relación (socioeconómicos, culturales, microbiota, etc.) (AU)

Background The incidence of eosinophilic esophagitis (EoE) is increasing in some regions of the world. Retrospective studies have found an inverse association with Helicobacter pylori infection (H. pylori). A recent prospective study has questioned this relationship. We aimed to evaluate this relationship in Mexican patients. Patients and methods We evaluated adult patients without prior eradication of H. pylori. Cases were defined by the presence of esophageal symptoms and >15 eosinophils/high power field (HPF) in the esophageal biopsy. Controls were defined by the presence of <15 eosinophils/HPF in esophageal biopsy. H. pylori infection was defined by histology. Patients were matched by age and gender assigning four controls per case. Results We included 190 patients: 38 cases and 152 controls. Cases had higher frequency of atopy, dysphagia, food impaction, peripheral eosinophilia, and endoscopic EoE abnormalities. The overall prevalence of H. pylori was 63.6%. Cases had significantly lower prevalence of H. pylori than controls (36.8% vs. 70.4%, OR 0.21 95% CI 0.08–0.69, p = 0.001). Atopic patients had lower prevalence of H. pylori than non-atopic: 13.1% vs. 50.5% (OR 0.20, 95% CI 0.06–0.69, p < 0.001), particularly allergic rhinitis and food allergy. Conclusions We observed an inverse relationship between H. pylori and EoE as well as atopy. Studies in experimental models of EoE that clarify the role of H. pylori in this interaction are required, as well as robust studies that include other factors (socioeconomic, cultural, microbiota, etc.) in order to clarify this relationship (AU)

RESUMEN

Non-alcoholic fatty liver disease (NAFLD) affects one-third of the world's adult population and is linked to metabolic syndrome. It can progress to steatohepatitis, cirrhosis and hepatocellular carcinoma. During the last four decades, it has been the subject of exhaustive research in multiple aspects to define its epidemiology, pathophysiological mechanisms and therapy. In 2020, a group of international experts proposed the change of name to metabolic-associated fatty liver disease (MAFLD) with the main objective of making it an inclusive diagnosis prioritizing metabolic abnormalities. However, the change in terminology included the modification of the diagnostic criteria allowing the non-exclusion of other concomitant liver diseases such as alcohol liver disease, and chronic hepatitis B or C. The proposal precipitated a wave of debates among experts based on theoretical opinions on the desirability of the rapid adoption of the new terminology. But it also precipitated a wave of epidemiological and clinical studies which, two years later, have provided clinical evidence on the differences and similarities of the two entities, specially, those that could be considered for future refinements of the diagnostic criteria of MAFLD. Likewise, this evidence may contribute to deciding the time of adoption of this terminology. In this text, we discuss, in general terms, important aspects of the clinical evidence that has been generated to date in cross-sectional and longitudinal studies focusing on clinical characteristics and outcomes, mainly on all-cause and specific mortality of MAFLD.

RESUMEN

INTRODUCTION: Angiodysplasias are responsible of 50% of small bowel bleeding. An endoscopic method that allows measuring its severity is not available. AIMS: The aim of the study was to validate a new endoscopic score with VCE to measure the severity of small bowel angiodysplasias (SBAD). METHODS: Four endoscopists independently reviewed VCE videos of 22 patients with SBAD. The score graded 3 variables: A - extent of lesions: E1, located in one half of the intestine and E2, in both halves; B - number of lesions: N1, <5; N2, 5-10; and N3, >10 lesions; C - probability of bleeding: P1, pale red spots; P2, bright red spots; P3, bleeding stigmata; and P4, active bleeding. Capsule Endoscopy Small Bowel Angiodysplasia Activity Index (CESBAI) was calculated as follows: E × 1 + N × 2 + P × 3. Interobserver variability was analyzed by Spearman's correlation and agreement Kappa statistic tests. RESULTS: The mean CESBAI scores by observers were O1= 11.6 ± 4.1; O2 = 11.3 ± 4.8; O3 = 11.1 ± 4.9; and O4 = 11.8 ± 4.2 (p > 0.05). Spearman's correlation values of CESBAI between every 2 observers were from 0.61 to 0.94 (p < 0.001) with a global correlation of 0.73 among all observers. Kappa values of CESBAI between every 2 observers ranged from 0.42 to 0.87 (p < 0.001) with a global agreement of 0.57 among all observers. All evaluators stated that the method was easy to use. CONCLUSIONS: CESBAI is a reliable and reproducible score. Nevertheless, these results must be validated in other studies with larger population before assessing its power for predicting bleeding recurrence.

RESUMEN

Eosinophilic enteritis is a rare disease with nonspecific symptoms, often representing a diagnostic challenge. Video capsule endoscopy (VCE) has enabled examination of the full small bowel. However, capsule retention is an unfortunate complication. We present the case of a female patient admitted for abdominal pain. Appendectomy without resolution of symptoms was performed. A normal computed tomography and magnetic resonance imaging were obtained. The diagnosis was made by VCE and double balloon enteroscopy with biopsy. Asymptomatic capsule retention was resolved after corticosteroid therapy. The patient showed a favorable clinical and endoscopic response, confirmed through a second VCE after 3 months of treatment.
