ABSTRACT

The COVID-19 pandemic has forced the establishment of preventive measures against contagion during the performance of diagnostic and therapeutic tests in gastroenterology. Digestive tract motility tests involve an intermediate and elevated risk for the transmission of COVID-19 infection. Given their elective or non-urgent indication in the majority of cases, we recommend postponing those tests until significant control of the infection rate in each Latin American country has been achieved during the pandemic. When the health authorities allow the return to normality, and in the absence of an effective treatment for or preventive vaccine against COVID-19 infection, we recommend a strict protocol for classifying patients according to their infectious-contagious status through the appropriate use of tests for the detection of the virus and the immune response to it, and the following of protective measures by the healthcare personnel to prevent contagion during the performance of a gastrointestinal motility test.

ABSTRACT

BACKGROUND: Irritable Bowel Syndrome (IBS) is characterized by the worsening of symptoms with a high fiber diet. This intolerance could be related to an increase in colonic bacterial fermentation. The hydrogen breath test (HBT) is a marker of the intestinal micro flora fermentative capacity. AIM: To assess if there is an association between hydrogen (H2) levels and clinical changes between diets with and without bran. PATIENTS AND METHODS: 10 women with predominantly constipated irritable bowel syndrome (Rome II criteria) received a lowfiber diet during one week. This phase was followed by a second 7 day period with the same diet but supplemented with 12 g of crude dietary fiber. At the end of both periods, patients completed a symptom scale (Lickert type) and performed a HBT. RESULTS: Comparing both periods with a different diet the median difference in the clinical scale score (-2.5) shows a tendency favorable to the diet without bran, p = 0.048. In the fiber period the median increase of 2 ppm in H2 values was not significant deferent. Neither was possible to establish an association between breath H2 and the clinical response to a fiber diet. CONCLUSIONS: In this pilot study we could not detect ary association between breath H2 levels and the clinical response to dietary fiber.(AU)


Introducción: Los pacientes con síndrome del intestino irritable (SII) frecuentemente agravan sus síntomas cuando incorporan fibra insoluble en su dieta. Esta intolerancia podría estar relacionada con una incrementada fermentación colónica. El nivel de hidrógeno en el aire espirado es una variable dependiente de la capacidad fermentativa del contenido bacteriano del intestino por lo que podría representar un recurso capaz de predecir el grado de intolerancia a la fibra dietética. Objetivo: El objetivo de este estudio piloto fue investigar si existe una asociación entre los niveles de hidrógeno (H2) en el aire espirado y la respuesta clínica a las dietas con y sin fibra. Pacientes y métodos: En este estudio piloto se incluyeron diez mujeres afectadas de síndrome de intestino irritable con constipación (Criterios Roma II). Siguieron una dieta poco fermentable durante 14 días. En la primera semana las pacientes se sujetaron a la dieta sin ningún agregado, en la segunda semana incorporaron 12 gr diarios de fibra dietaria cruda. Al finalizar ambos períodos las pacientes completaron una escala de Lickert de 7 ítems donde se valoró la respuesta clínica a la dieta administrada y se midió la excreción de H2 en el aire espirado. Resultados: Comparando ambas dietas, se observó que la mediana de las diferencias de los puntajes clínicos (-2,5) indicaba una tendencia favorable a la dieta poco fermentable sin fibra, p=0,048. El incremento de la mediana de la concentración de H2 en el aire espirado fue de 2 ppm para la dieta con fibra, pero el mismo no fue significativo. Tampoco se pudo demostrar una tendencia que permitiera relacionar los valores de H2 con la respuesta clínica a la fibra dietética. Conclusión: Los resultados de este estudio no lograron demostrar una asociación entre los niveles de hidrógeno en el aire espirado y la respuesta clínica a la dieta con fibra.(AU)

ABSTRACT

Solitary gastric plasmacitomas are infrequent tumors. They account for 5% of the extramedullary plasmacitomas. We report an unusual case in a 14 years old boy. The patient has had gastric symptoms for 2 years prior to an endoscopic examination. A fungating, ulcerated lesion was observed in the antrum. The biopsies showed a monoclonal, Lambda positive, diffuse, plasmocitic proliferation infiltrating the mucosa. Also a moderate number of Helicobacter pylori were identified in the gastric pits and numerous lymphoid follicules were observed in the deep portion of the mucosa. In view of the presence of HP infection the patient was treated with Orneprazole and Clarithromycin. Endoscopic examination and biopsies performed 3 and 5 months later showed a complete remission of the gastric lesion. At the time of this report the patient is in good physical condition, has recovered his weight and has grown 5 cm. Differential diagnosis with plasmo limpho in chronic gastritis and with lympheicitic lymphoma with plasmocitoid features had to be done. The macroscopic appearance of the gastric lesion, the absence of other inflammatory cells and monoclonality of the plasmocitic infiltration ruled out chronic gastritis. The negative staining for CD 20 as well as the abscence of lymphoid cells in the mucosal infiltrate give support: to the diagnosis of plasmocitoma. The close association between gastric MALT lymphoma and HP infection has been reported as well as its regression after antibiotic treatment for its erradication. In our review of the literature we failed to find any references to the association of HP with gastric plasmocitoma nor to its regression after antibiotic therapy.
