Incidence and characterization of aerophagia in dogs using videofluoroscopic swallow studies.

BACKGROUND: Aerophagia (ingestion of air), is a functional aerodigestive disorder in people. Criteria for diagnosis of aerophagia in dogs are >1/3 of bolus volume containing air or ingested air resulting in gastric distention (>1/3 of end gastric volume). Aerophagia is highlighted during eating and drinking. Videofluoroscopic swallow studies (VFSS) document aerophagia in dogs, but the incidence, clinical signs (CS), and associated disorders are unknown. OBJECTIVES: Identify the incidence of aerophagia, compare CS between dogs with and without aerophagia, and identify associated and predisposing disorders using VFSS. ANIMALS: A total of 120 client-owned dogs. METHODS: Sequential VFSS and associated medical records from dogs presenting to veterinary teaching hospitals at Auburn University and the University of Missouri were retrospectively reviewed. Statistical comparisons were made using Mann-Whitney and chi-squared tests, odds ratios (OR), and multiple logistic regression (P < .05). RESULTS: The incidence (95% confidence interval [CI]) of aerophagia was 40% (31.7-48.9). Dogs with mixed CS (gastrointestinal [GI] and respiratory; P < .001, 58.3%) were more likely to have aerophagia than dogs with exclusively respiratory CS (25%). Aerophagia was significantly more common in brachycephalic dogs (P = .01; 45.8% vs 13.8%), dogs with nonbrachycephalic upper airway obstruction (P < .001; 33.3% vs 4.1%), pathologic penetration and aspiration (P-A) scores (P = .04; 41.6% vs 23.6%), and gagging (P < .001; 25% vs 11.7%). Mixed CS (P = .01), brachycephaly (P < .001), and upper airway obstruction (P < .001) were independent predictors of aerophagia. CONCLUSIONS AND CLINICAL IMPORTANCE: Aerophagia was common, particularly in dogs with mixed CS. Brachycephalic dogs and dogs with upper airway obstruction are predisposed. Aspiration risk was high, emphasizing overlapping upper aerodigestive pathways.

Roles of swallowing and belching in different phenotypes of gastroesophageal reflux disease.

BACKGROUND: The contributions of swallowing and belching to specific gastroesophageal reflux disease (GERD) phenotypes are unclear. METHODS: This study retrospectively analyzed esophageal pH/impedance studies, comparing reflux events preceded by gastric belching (GB), supragastric belching (SGB), air swallowing, and liquid/solid swallowing based on reflux position, lower esophageal sphincter (LES) pressure, and acid exposure time (AET). KEY RESULTS: 20 GERD patients and 10 controls were studied. Upright GERD patients and controls had a higher proportion of reflux events with a preceding swallow or belch (0.64, 0.64) than the supine group (0.38, p = 0.043). The upright group and controls trended toward a higher proportion of reflux events preceded by overall swallowing (0.61, 0.50) and air swallowing (0.55, 0.48) than the supine group (0.32, 0.31 p = 0.064, p = 0.11), but the three groups had similar rates of liquid/solid swallowing (0.032, 0.024, 0.017, p = 0.69). LES pressure did not correlate with reflux events preceded by swallowing (R2 = 0.021, p = 0.44). There was a higher rate of events preceded by gastric belching in the control group (0.14) than in the upright (0.032) and supine groups (0.066, p = 0.049). LES pressure did not correlate with the rate of events preceded by belching (R2 = 0.000093, p = 0.96). Normal AET patients had a higher rate of events preceded by GB (0.12) than those with increased acid exposure (0.030, p = 0.0083), but the two groups had similar rates of preceding air (0.43, 0.47, p = 0.68), liquid/solid (0.018, 0.032, p = 0.30), and overall swallowing (0.44, 0.53, p = 0.38). CONCLUSIONS AND INFERENCES: Swallowing more than belching is a dominant mechanism for reflux irrespective of GERD position, LES pressure, and AET.

Does severe and chronic esophageal distension by air (observed in SGB and GB) affect the esophageal mucosa integrity (MNBI).

BACKGROUND: Supragastric belching (SGB) and aerophagia are behavioral disorders characterized by air induced esophageal distension. SGB is known to be associated with Gastro Esophageal Reflux Disease (GERD). Low Mean Nocturnal Baseline Impedance (MNBI) values support GERD diagnosis. We aimed to assess if chronic esophageal distension by air affects the esophageal mucosa integrity by assessing changes in MNBI. METHODS: In a single-center database study, we searched retrospectively for patients with a diagnosis of pathological SGB (n = 146) or aerophagia (n = 34) based on impedance-pH reflux monitoring. During the examined period, patients with a conclusive negative diagnosis of SGB and no evidence of aerophagia were used as a control cohort (n = 191). MNBI at 3, 5, and 17 cm over Lower Esophageal Sphincter (LES) was evaluated. GERD was diagnosed if acid exposure time (AET) >6%. All impedance studies of included patients were prospectively reevaluated. RESULTS: GERD was diagnosed in 31.7% patients with SGB, a rate not different in comparison to patients without SGB (30.8%, p = 0.906). MNBI at 3 and 5 cm above the LES was significantly decreased among patients with SGB. SGB was not correlated with MNBI at 3 cm over the LES, (p: 0.086 OR: 1.000 95% CI: 0.999-1.001) when using multivariate analysis. Moreover no difference was spotted as far as MNBI at 3, 5, and 17 cm over the LES is concerned among patients with or without aerophagia. CONCLUSION: Even if patients with SGB do show lower MNBI values, esophageal distention due to excessive air movement does not directly lead to impairment of esophageal mucosa integrity.

INTRODUCTION. The difficulty to swallow or dysphagia is included within the problems of swallowing, which represent all the alterations of the physiological process in charge of carrying the food from the mouth to the esophagus, and then to the stomach, always taking into account the protection of the airways. OBJECTIVE. To define the optimal management, both clinical and surgical, for the adequate treatment of dysphagia produced as a consequence of severe SARS-CoV-2 infection. METHODOLOGY. A review of the scientific literature was carried out using both PubMed and Elsevier databases, which relate the management of dysphagia and patients with a history of severe SARS-CoV-2 infection. RESULTS. The incidence of dysphagia following severe SARS-CoV-2 infection was of 23,14%, with mild dysphagia being the most frequent 48,00%. The most frequently used clinical treatments for dysphagia management were oral rehabilitation and change in dietary texture in 77,23% of cases, while tracheotomy was the only surgical treatment used 37,31%. A total of 12,68% of patients recovered their swallowing function without specific treatment. The efficacy of clinical and surgical treatments in survivors of severe SARS-CoV-2 infection was 80,68%, with a mean resolution time of 58 days. CONCLUSION. An adequate medical history is key to the diagnosis of post-COVID-19 dysphagia. Treatment can range from conservative management such as changes in diet texture to more invasive treatments such as tracheotomy to improve swallowing function.

Anxiety correlates with excessive air swallowing and PPI refractoriness in patients with concomitant symptoms of GERD and functional dyspepsia.

BACKGROUND: Anxiety may exacerbate GERD and FD symptoms perception and reduce quality of life. As many as 50% of patients with GERD symptoms have incomplete relief with PPI therapy, and psychological factors may influence PPI responsiveness. AIM: The potential relationship between anxiety, excessive air swallowing, and PPI responsiveness was evaluated. METHODS: GERD patients with concomitant FD were prospectively evaluated. Validated structured questionnaires were used to evaluate anxiety, GERD, and FD symptoms. All patients were treated, within the previous year, with at least 8 weeks of standard dose PPI therapy. RESULTS: One hundred sixty-one patients were included. Frequency of non-responders in patients with moderate/severe anxiety was significantly higher compared to patients with mild anxiety (62.7% vs. 37.3%, p < 0.01). Patients with moderate/severe anxiety displayed a significantly higher mean FD symptoms score value compared to patients with mild anxiety. A significantly higher mean number of air swallows were observed in patients with moderate/severe anxiety. At ROC analysis, air swallows and mixed reflux episodes were significantly associated with the presence of PPI refractoriness (AUC: 0.725, 95% CI: 0.645-0.805 and 0.768, 0.692-0.843). According to univariate analysis, an abnormal number of air swallows, mixed reflux episodes and presence of moderate/severe anxiety was significantly associated with PPI refractoriness. CONCLUSION: Our results, if confirmed in in a larger, prospective clinical and therapeutic study, demonstrate the usefulness of an up-front evaluation with anxiety questionnaire and esophageal testing in patients with a broad spectrum of upper gastrointestinal symptoms who fail to respond to PPI treatment, supporting the option of alternative treatment modalities.

Relevance of Excessive Air Swallowing in GERD Patients With Concomitant Functional Dyspepsia and Poor Response to PPI Therapy.

GOALS: The present study was aimed at evaluating the possible role of air swallowing in the association between gastroesophageal reflux disease (GERD) symptoms and concomitant functional dyspepsia (FD) and their role in GERD symptom persistence despite proton pump inhibitor (PPI) therapy. BACKGROUND: It has been shown that individuals with excessive air swallowing experience FD. It has been also demonstrated that a consistent group of GERD patients not responding to PPI therapy swallow more air during mealtime and also have more mixed refluxes. MATERIALS AND METHODS: Multichannel intraluminal impedance-pH tracings from consecutive patients were retrospectively evaluated. A validated structured questionnaire was used to evaluate GERD and concomitant FD symptoms. All patients were treated, within the previous year, with at least 8 weeks of standard-dose PPI therapy. RESULTS: A total of 35 patients with conclusive GERD, 35 patients with reflux hypersensitivity, and 35 with functional heartburn were studied. A direct relationship was observed between the number of air swallows and of mixed refluxes ( R =0.64). At receiver operating characteristic curve analysis, air swallows and mixed refluxes were significantly associated to the presence of FD and PPI refractoriness. An air swallow cutoff of 107 episodes/24 hours was identified to discriminate patients with and without FD (sensitivity: 87%, specificity: 82.8%). A mixed reflux cutoff of 34 episodes/24 hours was identified to discriminate PPI responders from nonresponders (sensitivity: 84.8%, specificity: 69%). At multivariate analysis, an abnormal number of air swallows and of mixed refluxes were significantly associated to FD and PPI refractoriness. CONCLUSION: Our study highlights the relevant role of excessive air swallowing in eliciting both dyspepsia and refractoriness of typical GERD symptoms to PPI therapy.

Epidemiology of aerophagia in children and adolescents: A systematic review and meta-analysis.

BACKGROUND: Aerophagia is a common functional gastrointestinal disorder among children. The disease leads to symptoms related to air in the intestine leading to burping, abdominal distension, and excessive flatus. We aimed to perform a systematic review and a meta-analysis to assess the epidemiology of aerophagia in children. METHODS: We conducted a thorough electronic databases (MEDLINE, EMBASE, PsycINFO and Web of Science) search for all epidemiological surveys conducted in children on aerophagia. All selected studies were assessed for their scientific quality and the extracted data were pooled to create a pooled prevalence of aerophagia. RESULTS: The initial search identified 76 titles. After screening and in depth reviewing, 19 studies representing data from 21 countries with 40129 children and adolescents were included in the meta-analysis. All studies have used standard Rome definitions to diagnose aerophagia. The pooled prevalence of aerophagia was 3.66% (95% Confidence interval 2.44-5.12). There was significant heterogeneity between studies [I2 98.06% with 95% Confidence interval 97.70-98.37). There was no gender difference in prevalence of aerophagia in children. The pooled prevalence of aerophagia was highest in Asia (5.13%) compared to other geographical regions. CONCLUSION: In this systematic review and meta-analysis, we found aerophagia has a significant prevalence across the world.

Prevalencia y factores de riesgo del comportamiento anormal estereotipado aerofagia en el caballo criollo colombiano / Prevalence and Risk Factors of Abnormal Stereotyped Crib-Biting Behavior in the Colombian Creole Horse

RESUMEN La aerofagia es la estereotipia clásica más común en los equinos, con una etiología poca entendida; sin embargo, se reconoce por ser de naturaleza multifactorial. Además, se ha asociado con efectos negativos sobre la salud de los equinos portadores. El objetivo de este estudio fue describir los factores de riesgo y la frecuencia de presentación de la aerofagia en una población de caballos criollos colombianos (CCC). Fueron encuesta-dos 42 criaderos, entre los que se presentó un total de 1063 CCC (488 machos y 575 hembras). De esta población, el 5,27% (56 animales) fue plenamente identificado con aerofagia. Esta prevalencia fue superior a la mayoría de otros reportes de Sur América. La aerofagia, posiblemente obedeció tanto a factores inherentes al animal como a factores externos relacionados con el manejo; sin embargo, se requiere el diseño de estudios longitudinales sobre prácticas de manejo y de líneas dentro de la raza para cuantificar y validar la información relacionada con la posible predisposición genética o racial a la aerofagia y a otras estereotipias y comportamientos anormales observados en estos animales.

ABSTRACT Crib-biting is the most common classic stereotype in equines, with a poorly understood etiology; however, it is recognized for being multifactorial in nature. Furthermore, it has been associated with negative effects on the health of horses. The objective of this study was to describe the risk factors and the frequency of presentation of crib-biting in a population of Colombian Creole Horses (CCC by its Spanish acronym). We surveyed Forty-two properties, which meant a total of 1063 CCC (488 males and 575 females). Of this population, 5,27% (56 animals) were fully identified with crib-biting. This prevalence was higher than most other reports in South America. Crib-biting is possibly due to both inherent of the animal and external factors related to management; however, the design of longitudinal studies on management practices and genetic lines within the breed is required to quantify and validate the information related to the possible genetic or racial predisposition for this and other stereotypes and abnormal behaviors observed in horses.

Aerophagia Study in Indonesia: Prevalence and Association With Family-related Stress.

BACKGROUND: Aerophagia is a functional gastrointestinal disorder characterized by repeated air swallowing leading to chronic abdominal distension. Symptoms can be long lasting, lead to frustration, and distress. This study describes prevalence, related factors, and symptomatology of aerophagia, together with its relationship with emotional stress. MATERIALS AND METHODS: Cross-sectional study. Adolescents aged 10 to 17 years from selected state schools by convenient sampling from Jakarta, Indonesia, were recruited. Rome III self-administered questionnaire was used to compile data on gastrointestinal symptoms. Data on sociodemographic characteristics, intestinal and extraintestinal symptoms, and stressful life events were collected using a separate questionnaire. RESULTS: A total of 1796 questionnaires were included in the analysis [males 732 (40.8%), mean age 13.58 (SD 0.992) years]. There were 81 (4.5%) subjects diagnosed with aerophagia. When the criterion of belching was removed from the diagnosis of aerophagia, the prevalence drops to only 2 (0.1%). subjects. Bivariate analysis showed that sociodemographic factors have no correlation with aerophagia. In subjects with aerophagia, among the intestinal-related and extraintestinal symptoms, only loss of appetite was significantly more common in the aerophagia population (33.3%) when compared with controls (22.8%). Death of a close family member [adjusted odds ratio (OR), 2.78; 95% confidence interval (CI), 1.46-5.31; P=0.002], divorce or separation of parents (adjusted OR, 2.54; 95% CI, 1.38-4.66; P=0.003), and divorce followed by separate individual remarriage of parents (adjusted OR, 2.01; 95% CI, 1.01-3.98; P=0.046) were found to be significantly associated with aerophagia by multivariate analysis. CONCLUSIONS: The prevalence of aerophagia was found in 4.5% of Indonesian school-aged children according to Rome III criteria, but the prevalence was found only 0.1% if the belching is removed from the criteria. Besides the main symptoms, only loss of appetite was significantly more common in aerophagia among intestinal-related and extraintestinal symptoms. Family-related stress showed a significant correlation with aerophagia.

[A single-center retrospective analysis of 46 children with aerophagia].

OBJECTIVE: To study the clinical features of aerophagia in children. MEYJODS: A retrospective analysis was performed on the medical data of 46 children with aerophagia who were diagnosed and treated in Children's Hospital Affiliated to Nanjing Medical University from October 2011 to September 2019. RESULTS: Among these 46 children, 15 (33%) had Tourette syndrome. Abdominal distension was the most common symptom and was observed in 45 children (98%). The 24-hour esophageal multichannel intraluminal impedance monitoring showed a mean number of 341 times of air swallowing and a mean number of 212 times of gas reflux, and 95% of gas refluxes occurred in the upright body position. Compared with those without Tourette syndrome, the children with Tourette syndrome had a significantly higher incidence rate of air swallowing symptoms (67% vs 6%, P<0.001), but there were no significant differences in other symptoms and the results of 24-hour esophageal impedance. Dietary adjustment, psycho-behavioral therapy, and drug intervention significantly improved the scores of clinical symptoms and quality of life, among which psycho-behavioral therapy was an important intervention measure. CONCLUSIONS: Some children with aerophagia may have Tourette syndrome, and such children are more likely to have air swallowing symptoms. Psycho-behavioral therapy is one of the most important treatment methods, and children with aerophagia tend to have a good prognosis after treatment.

Novel Use of Impedance Technology Shows That Esophageal Air Events Can Be Temporally Associated With Gastroesophageal Reflux Disease-like Symptoms.

A few studies have shown that esophageal air events (EAEs), such as air-swallows, may be associated with symptoms that have historically been associated with gastroesophageal reflux disease (GERD). To objectively test a hypothesis that all EAE types (air-swallows, supragastric belches and gastric belches) can be associated with GERD-like symptoms, we removed the impedance "tags" from the GER episodes (placed during autoscan) and instead tagged either air-swallows, supragastric belches or gastric belches in each of 3 copies of the 24-hour impedance tracing for 2 infant patients who presented with symptoms suggestive of GER as an etiology. Impedance system software (MMS) analyses revealed that, in both infants, all EAE types were significantly associated (SAP >95%) with 1 or more of the GERD-like symptom types (cough, pain/crying, back-arching, and gagging). These data underscore the importance of considering other diagnoses when developing management strategies for treating GERD-like symptoms in infants.

Aerofagia por disinergia abdómino-frénica en un niño de dos años / Aerophagia due to abdomino-phrenic dyssynergia in a 2-year-old child

Presentamos un niño previamente sano de dos años con importante distensión abdominal al que después de varias intervenciones con escasa respuesta se diagnosticó aerofagia patológica. La aerofagia patológica en pediatría es un trastorno infrecuente, casi exclusivo en niños con enfermedad neurológica de base. Puede ser motivo de múltiples exámenes complementarios y tratamientos agresivos innecesarios. La reciente publicación de un caso asocia la aerofagia con un novedoso concepto, la disinergia abdómino-frénica

We report the case of a previously healthy 2-year-old child who presented with significant abdominal distension. After several interventions that proved ineffective, pathologic aerophagia was eventually diagnosed. In pediatrics, pathologic aerophagia is an uncommon disorder that almost exclusively affects children with an underlying neurological condition. It may lead to multiple diagnostic tests and unnecessary aggressive therapies. A recent case report associated aerophagia with a novel concept of abdomino-phrenic dyssynergia

Aerophagia due to abdomino-phrenic dyssynergia in a 2-year-old child.

We report the case of a previously healthy 2-year-old child who presented with significant abdominal distension. After several interventions that proved ineffective, pathologic aerophagia was eventually diagnosed. In pediatrics, pathologic aerophagia is an uncommon disorder that almost exclusively affects children with an underlying neurological condition. It may lead to multiple diagnostic tests and unnecessary aggressive therapies. A recent case report associated aerophagia with a novel concept of abdomino-phrenic dyssynergia.
