Risk factors for functional dyspepsia, erosive and non-erosive gastroesophageal reflux disease: A cross-sectional study / Factores de riesgo en dispepsia funcional y enfermedad por reflujo gastroesofágico: un estudio transversal

Background: Conflicting data exists regarding risk factors associated with Gastroesophageal Reflux Disease (GERD) and Functional Dyspepsia (FD). Few studies examine anxiety/depression in relation to GERD phenotypes (Esophagitis/EE, and Non-Erosive Reflux Disease/NERD), FD, and Rome-IV syndromes. Our aim was to evaluate the association between epidemiological factors and comorbidities with GERD phenotypes, FD, and Rome-IV syndromes, as well as their relationship with anxiety/depression. Methods: 338 subjects were selected from 357 patients referred to three tertiary-centers for endoscopic evaluation. Every subject was interviewed individually to administer three validated questionnaires: GERD-Q, Rome-IV and HADS. Results: 45/338 patients were controls, 198/58.6% classified as GERD, 81/24.0% EE (49/14.5% symptomatic, and 32/9.5% asymptomatic), 117/34.6% NERD, 176/52.1% FD (43/12.7% epigastric pain syndrome, 36/10.7% postprandial distress syndrome, and 97/28.7% overlapping syndrome). 81 patients were mixed GERD-FD. Multivariate analysis found significant independent associations: age in NERD and FD; sex in EE, asymptomatic EE and FD; body mass index in NERD and FD; alcohol in EE; anxiety/depression in FD; use of calcium channel antagonists in EE; and inhalers in FD. We compared controls vs different groups/subgroups finding significantly more anxiety in NERD, FD, all Rome-IV syndromes, and mixed GERD-FD; more depression in FD, overlapping syndrome, and mixed GERD-FD; and higher levels of anxiety+depression in NERD, FD, overlapping syndrome, and mixed GERD-FD. Conclusions: NERD and FD share demographic and psychopathological risk factors which suggests that they may form part of the same pathophysiological spectrum. Regarding NERD anxiety was predominant, and in FD anxiety+depression, suggesting that both processes may require complementary psychological therapy.(AU)

Antecedentes: Existen datos controvertidos sobre los factores de riesgo asociados a la enfermedad por reflujo gastroesofágico (ERGE) y la dispepsia funcional (DF). Pocos estudios han evaluado la relación entre ansiedad/depresión y los diferentes fenotipos de la DF (criterios Roma IV) y de la ERGE (erosiva [EE] y no erosiva [NERD]). Nuestro objetivo fue valorar la asociación entre diferentes factores epidemiológicos y comorbilidades y los fenotipos de la ERGE, la DF y sus síndromes, y su relación con la ansiedad/depresión. Métodos: Se seleccionaron 338 pacientes entre 357 remitidos para estudio endoscópico en 3 hospitales terciarios. Cada uno fue entrevistado individualmente y completó 3 cuestionarios validados: GERD-Q, Roma IV y HADS. Resultados: Cuarenta y cinco de los 338 pacientes fueron controles. Se clasificaron 198/58,6% como ERGE, 81/24,0% como EE (49/14,5% sintomática y 32/9,5% asintomática), 117/34,6% como NERD y 176/52,1% como DF (43/12,7% síndrome de dolor epigástrico, 36/10,7% síndrome de molestias posprandiales y 97/28,7% solapamiento epigastralgia-molestias posprandiales). Ochenta y uno solapaban ERGE-DF. El análisis multivariante encontró las siguientes asociaciones significativas: edad en NERD y DF; sexo en EE, EE asintomática y DF; IMC en NERD y DF; alcohol en EE; ansiedad/depresión en DF; toma de antagonistas del calcio en EE e inhaladores en DF. Al comparar el grupo control vs. diferentes grupos/subgrupos encontramos significativamente más ansiedad en NERD, solapamiento DF-ERGE, DF y todos sus síndromes Roma IV; más depresión en DF, solapamientos epigastralgia-molestias posprandiales y ERGE-DF; y más ansiedad+depresión en NERD, DF y solapamientos epigastralgia-molestias posprandiales y ERGE-DF. Conclusiones: La DF y la NERD comparten factores de riesgo demográficos y psicopatológicos, lo que evidencia que forman parte de un mismo espectro fisiopatológico...(AU)

Preventive effect of zaprinast and 3-isobutyl, 1-methylxanthine (phosphodiesterase inhibitors) on gastric injury induced by nonsteroidal antiinflammatory drugs in rats.

Cyclic GMP plays an important role in maintaining homeostasis in the gastric mucosa. NSAIDs damage the mucosa by mechanisms that may be mediated by alterations in the intragastric concentration of cyclic GMP. To test this hypothesis we studied the effects of the oral administration of acetylsalicylic acid (100, 300, and 500 mg/kg), piroxicam (5, 10, and 20 mg/kg) and sodium diclofenac (10, 25, 50, and 100 mg/kg), and of their interaction with zaprinast (5 mg/kg) and IBMX (10 mg/kg), on intragastric concentrations of cyclic GMP and the gastric erosive index in rats. All determinations were done 3 hr after the NSAID was given. All NSAIDs induced dose-dependent decreases in mucosal concentrations of cyclic GMP, which correlated inversely with the surface area showing mucosal injury. In contrast, cyclic GMP concentrations remained normal, and no intragastric damage was seen in rats given zaprinast (cyclic GMP-specific phosphodiesterase inhibitor) or IBMX (non-specific phosphodiesterase inhibitor) or in combination with NSAIDs. These findings are in line with the hypothesis that cyclic GMP is involved in the biochemical mechanisms of NSAID-induced gastric injury.
