ABSTRACT

Introduction: Gastrointestinal symptoms such as heartburn, indigestion/dyspepsia, constipation and bloating are very common in every community. Our group applied a questionnaire in order to identify the presence of gastrointestinal symptoms. Methodology: In 2012, during the World Digestive Health Day a survey of 13 questions given by the World Gastroenterology Organization (WGO) was administered to a group of people (E) at the Clinical Hospital of the University of Chile (HCUCH); the questions were based on the presence and frequency of digestive symptoms. The results were compared with two other groups, one rural (R) and another comprised of people that were accompanying the patients attending HCUCH (group A) for examinations. A χ2 test was used to compare variables by group. Results: Total E = 270, A = 100, R = 69. Women: E = 212 (79 percent), A = 66 (66 percent), R = 43 (62.4 percent). Age E = 48, A = 44, R = 53 (p = 0.0003). Digestive discomfort: E = 94.8 percent (256), A = 81 percent (81), R = 85.5 percent (59) p = 0.000. Distension/bloating E = 94.44 percent (255), A = 84 percent (84), R = 81.2 percent (56) p = NS. Abdominal pain/discomfort E = 89.6 percent (242), A = 75 percent (75), R = 82.6 percent (57) p = 0.000. Constipation: E = 80 percent (216), A = 71 percent (71), R = 63.7 percent (44) p = 0.01, with significant differences in sensation of incomplete evacuation in the 3 groups p = 0.001. Heartburn E = 75.2 percent (203), A = 67 percent(67), R = 68.1 percent (47) p = NS. Reflux E = 74 percent (200), A = 69 percent (69), R = 68.1 percent (47) p = NS. Interference with sleep: E = 62.2 percent (168), A = 45 percent (45), R = 56.5 percent (39) p = 0.012. Problems with soft/mushy/liquid stools = 65.92 percent (178), A = 61 percent (61), R = 68.11 percent (47) p = NS. Conclusions: Over 80 percent of respondents provided an upset stomach. The control group had the highest prevalence of digestive symptoms...


Introducción: Síntomas digestivos como pirosis, indigestión/dispepsia, constipación y distensión son muy frecuentes en cada comunidad. Nuestro grupo aplicó un cuestionario con el objetivo de identificar la presencia de sintomatología digestiva. Metodología: En el año 2012, durante el día mundial de la salud digestiva (DMSD) se realizó en el Hospital Clínico de la Universidad de Chile (HCUCH), una encuesta propuesta por la Organización Mundial de Gastroenterología (OMGE) que incluía 13 preguntas basadas en la presencia y frecuencia de síntomas digestivos. La encuesta se hizo a un grupo de personas (E). Los resultados fueron comparados con otros dos grupos, uno rural (R) y otro conformado por acompañantes (A) de pacientes que acudieron a exámenes al HCUCH. Se realizó una prueba χ² para comparar variables por grupo. Resultados: Total E = 270; A = 100; R = 69. Mujeres: E = 212 (79 por ciento), A = 66 (66 por ciento), R = 43 (62,4 por ciento). Edad E = 48, A = 44, R = 53 (p = 0,0003). Molestias digestivas: E = 94,8 por ciento (256), A = 81 por ciento (81); R = 85,5 por ciento (59) p = 0,000. Distensión/hinchazón E = 94,44 por ciento (255), A = 84 por ciento (84), R = 81,2 por ciento (56) p = NS. Dolor/molestia abdominal E = 89,6 por ciento (242), A = 75 por ciento (75), R = 82,6 por ciento (57) p = 0,000. Constipación: E = 80 por ciento (216), A = 71 por ciento (71), R = 63,7 por ciento (44) p = 0,01, existiendo diferencias significativas en sensación de evacuación incompleta en los 3 grupos p = 0,001. Pirosis E = 75,2 por ciento (203), A = 67 por ciento (67), R = 68,1 por ciento (47) p = NS. Reflujo E = 74 por ciento (200), A = 69 por ciento (69), R = 68,1 por ciento (47) p = NS. Interferencia con el sueño: E = 62,2 por ciento (168), A = 45 por ciento(45), R = 56,5 por ciento (39) p = 0,012. Problemas de heces blandas/ pastosas/líquidas E = 65,92 por ciento (178), A = 61 por ciento (61), R = 68,11 por ciento (47) p = NS...

ABSTRACT

This is a short review related with the current concepts and controversies in the diagnosis of intestinal bacterial overgrowth. This is a relatively complex entity present in diverse pathologies. Its adequate diagnosis has impact in the therapy and management of the patients with this condition. (AU)

ABSTRACT

Hydrogen breath test (HBT) for diagnosis of lactose malabsorption (LM), is usually performed over a 180 min standard period. However, studies have suggested that extending the observation time, the sensibility of the test is improved. Aims: To determine if the time extension of the lactose hydrogen breath test, can improve sensibility of the test. Patients and method: One thousand and two hundred and ninety three patients were included, mean age 33.1 years (range: 3-90 years), 73.3 percent women, 26.8 percent were younger than 15years. Lactose HBT was performed for a standard period, which was prolonged to 240 min when patients presented a flat curve at 180 min. Results: Seven hundred and thirty one patients (56.5 percent) had a positive breath test for LM during 180 min. The extension of the HBT to 240 min showed an increase of 13.3 percent (p < 0.05) of patients with LM diagnosis. Conclusion: This study shows that an additional hour increases sensibility of the test, and decreases the false negative results.


El test de hidrógeno en aire espirado (TH2) para el diagnóstico de malabsorción de lactosa (ML) se realiza por un período estándar de 180 min. Sin embargo, se ha sugerido que estudios de mayor duración podrían mejorar la sensibilidad del test. Objetivos: Determinar si la prolongación del TH2 con lactosa, puede mejorar la sensibilidad del diagnóstico de ML. Pacientes y Métodos: Se estudiaron 1293pacientes, edad promedio 33,1 años (rango 3 a 90 años), 73.3 por ciento mujeres, 26,8 por ciento menores de15 años. Para determinar la presencia de ML se realizó el TH2 con lactosa estándar, extendiéndolo a 240 min en pacientes con una curva plana a los 180 min. Resultados: Setecientos treinta y un pacientes (56,5 por ciento) tuvieron un TH2 concordante con ML durante el período de 180 min. En aquellos que se extendió el examen a 240 min se observó un aumento de 13,3 por ciento de ML (p< 0,05). Conclusión: Este estudio demuestra que la prolongación del TH2 en una hora mejora la sensibilidad del examen y disminuye el número de falsos negativos.

ABSTRACT

El test de hidrógeno (H2) en aire espirado es ampliamente utilizado en el estudio de malabsorción de hidratos de carbono, sobrecrecimiento bacteriano intestinal (SBI) y tiempo de tránsito orocecal (TTOC). Objetivo: Comparar los resultados obtenidos por dos equiposde detección de H2, uno de ellos de introducción reciente en nuestro medio. Material y Métodos: 50 pacientes, edad promedio 38,5 +/- 5,2 años (rango 7-77 años), 40 mujeres, se les realizó el test de H2 en aire espirado en paralelo con ambos equipos bajo métodos estandarizados. En 25 de ellos se investigó la presencia de malabsorción de lactosa, y en los otros 25, la presencia de SBI con lactulosa. Se evaluaron los valores de H2 obtenidos con ambos equipos. Resultados: Las lecturas de H2 con ambos equipos no mostraron diferencias significativas tanto para lactosa (p > 0,1), como para lactulosa (p > 0,5). Tampoco hubo diferencias en el TTOC de los pacientes (90 +/- 33,75 min v/s 90.8 +/- 32,42 min) (p > 1). Se obtuvo un índice de concordancia Kappa de 0,92 entre ambos equipos con el test con lactosa y con lactulosa. Conclusión: El equipo portátil es altamente confiable, entregando resultados con una excelente concordancia con respectoal equipo de referencia.


The hydrogen (H2) breath test (BT) is widely used to investigate carbohydrates malabsorption, small intestinal bacterial overgrowth (SIBO) and orocaecal transit time (OTT). Aim: To compare the results of two hydrogen breath devices, one of them, of recent introduction in our country. Methods: Fifty patients were included, mean age 38.5 +/- 5.2years (range 7-77 yrs), 40 women, H2 BT was performed in parallel with both analyzers under standardized methods. Lactose malabsorption was investigated in 25 patients with lactose, and the presence of SIBO in the resting 25 patients, with lactulose, hydrogen values obtained with both devices were evaluated. Results: No differences were observed between the H2 concentrations for lactose BT (p > 0.1) as well as lactulose BT (p > 0.5)and also between the OTT measured by the two devices (90 +/- 33.75 min. v/s 90.8 +/- 32.42 min) (p > 1). We detected a Kappa concordance index of 0.92 for both equipments. Conclusion: The portable device is highly reliable to detect the presence of breath hydrogen, giving results with an excellent concordance to the reference device.
