Abstract

Existen controversias sobre la prevalencia del síndrome de intestino irritable (SII)-postinfeccioso (PI), sobrepoblación bacteriana (SPB), alteraciones en la microbiota, inflamación de bajo grado y antibioticoterapia en SII. Realizar una revisión basada en evidencia de estos factores. Se realizó una revisión de la literatura hasta julio del 2012 y se incluyeron artículos adicionales hasta agosto del 2013, los cuales fueron analizados mediante el sistema del Centro para Medicina Basada en Evidencia de la Universidad de Oxford (OCEBM). 1. Existe mayor probabilidad de SPB mediante pruebas de aliento pero la prevalencia es muy variable (2-84%). 2. La microbiota intestinal es diferente en SII que en sujetos sanos, pero no se ha establecido una característica común presente en todos los pacientes. 3. La incidencia y prevalencia del SII-PI varía del 9-10% y 3-17%, respectivamente; esta última disminuye con el tiempo. La etiología bacteriana es la más frecuente, pero se han reportado casos posvirales y parasitarios. 4. Existe un subgrupo de pacientes con incremento de células enterocromafines, linfocitos intraepiteliales y mastocitos en la mucosa intestinal, pero no se han determinado diferencias entre SII-PI y SII-No PI. 5. La microbiota metanogénica se asocia con el SII con estreñimiento. 6. La rifaximina en dosis de 400 mg TID/10 días o 550 mg TID/14 días es efectiva en la mejoría de síntomas globales y distensión abdominal en SII. La efectividad del retratamiento parece ser similar a la del primer ciclo. Se requieren más estudios para determinar la microbiota intestinal propia del SII y las diferencias en inflamación de bajo grado entre SII-PI y SII-No PI. La rifaximina ha demostrado efectividad en el tratamiento del SII independientemente de los factores anteriores. Post-infectious irritable bowel syndrome (PI-IBS) prevalence, small intestinal bacterial overgrowth (SIBO), altered microbiota, low-grade inflammation, and antibiotic therapy in IBS are all controversial issues. To conduct an evidence-based review of these factors. A review of the literature was carried out up to July 2012, with the inclusion of additional articles as far as August 2013, all of which were analyzed through the Oxford Centre for Evidence-Based Medicine (OCEBM) system. 1. There is greater SIBO probability in IBS when breath tests are performed, but prevalence varies widely (2-84%). 2. The gut microbiota in individuals with IBS is different from that in healthy subjects, but a common characteristic present in all the patients has not been established. 3. The incidence and prevalence of PI-IBS varies from 9-10% and 3-17%, respectively, and the latter decreases over time. Bacterial etiology is the most frequent but post-viral and parasitic cases have been reported. 4. A sub-group of patients has increased enterochromaffin cells, intraepithelial lymphocytes, and mast cells in the intestinal mucosa, but no differences between PI-IBS and non-PI-IBS have been determined. 5. Methanogenic microbiota has been associated with IBS with constipation. 6. Rifaximin at doses of 400 mg TID/10 days or 550 mg TID/14 days is effective treatment for the majority of overall symptoms and abdominal bloating in IBS. Retreatment effectiveness appears to be similar to that of the first cycle. Further studies are required to determine the nature of the gut microbiota in IBS and the differences in low-grade inflammation between PI-IBS and non-PI-IBS. Rifaximin has shown itself to be effective treatment for IBS, regardless of prior factors.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • These broad-spectrum antibiotics are absorbable, causing local and systemic side effects.

    “however, these drugs are absorbable causing local and systemic side effects”
  • Other broad-spectrum antibiotics reducing bacterial overgrowth have been challenged in the treatment of IBS, including tetracycline, amoxicillin clavulanate, metronidazole and fluoroquinolones such as norfloxacin.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
