RESUMO
INTRODUCTION: the activation of mast cells causes alterations in epithelial and neuromuscular function and is involved in visceral hypersensitivity and dysmotility in gastrointestinal functional disorders. OBJECTIVES: primary: to evaluate differences in basal serum tryptase (BST) between patients with irritable bowel syndrome (IBS) and healthy controls. Secondary: BST depending on IBS subtype (diarrhea: IBS-D; constipation: IBS-C), comorbidities and correlation with IBS severity and quality of life. MATERIAL AND METHODS: a prospective control-case study in IBS patients (Rome IV criteria). BST (ImmunoCAP-Phadia, Sweden®), IBS Severity Score (IBSSS), pain, bloating and flatulence analogue scales, IBS quality of life (IBSQOL), and patient health status (PHQ-9) were determined. BST is the primary variable to achieve the primary endpoint. RESULTS: thirty-two patients were included, 21 (65.6 %) with IBS-D and 11 (34.4 %) with IBS-C; 32 controls were also included. Mean IBSSSS: 326.6 (± 71.4), IBSQOL: 76 (± 20.3), and PHQ9: 10.2 (± 5.9). BST was 4.8 ± 2.6 in IBS and 4.7 ± 2.6 in controls (p = 0.875). There were no differences in BST between IBS subtypes (4.7 ± 2.9 in IBS-D and 5 ± 1.8 in IBS-C; p = 0.315) or IBS severity (p = 0.662). However, BST was higher in patients with IBS and extraintestinal comorbidities compared to other patients and controls (p = 0.029). This subgroup also has more severe bloating (p = 0.021). There was no correlation between BST, quality of life (p = 0.9260), and health status (p = 0.3985). CONCLUSION: BST does not discriminate between IBS patients and controls. However, BST was higher in patients with IBS with extraintestinal comorbidities, which had more severe bloating. This finding is worthy of investigation.

BACKGROUND: lung transplantation (LTx) is a viable option for most patients with end-stage lung diseases. Esophageal motor disorders (EMD) are frequent in candidates for LTx, but there is very little data about changes in esophageal motility post-LTx. AIM: the aim of our study was to assess esophageal motor disorders by high resolution manometry (HRM) both pre-LTx and six months post-LTx in patients with and without organ rejection. STUDY: HRM (Manoscan®) was performed in 57 patients both pre-LTx and six months post-LTx. HRM plots were analyzed according to the Chicago classification 3.0. RESULTS: EMD were found in 33.3% and in 49.1% of patients pre-LTx and post-LTx, respectively, and abnormal peristalsis was more frequently found post-LTx (p = 0.018). Hypercontractile esophagus was frequently found post-LTx (1.8% and 19.3% pre-LTx and post-LTx, respectively). Esophagogastric junction (EGJ) morphology changed significantly pre-LTx and post-LTx; type I (normal) was more frequent post-LTx (63-2% and 82.5% respectively, p = 0.007). EMD were more frequent post-LTx in both the non-rejection and rejection group, although particularly in the rejection group (43.2% and 69.2% respectively, p = 0.09). EMD such as distal spasm, hypercontractile esophagus and EGJ outflow obstruction were also observed more frequently post-LTx in the rejection group. CONCLUSION: significant changes in esophageal motility were observed pre-LTx and particularly post-LTx; hypercontractile esophagus was a frequent EMD found post-LTx. EMD were more frequent in the group of patients that experienced organ rejection compared to the non-rejection group. EMD leading to an impaired esophageal clearance should be considered as an additional factor that contributes to LTx failure.

BACKGROUND: High-resolution manometry (HRM) is a breakthrough in the morphological study of the gastroesophageal junction (GEJ) and its degrees of disruption. OBJECTIVES: a) Assessment of risk factors involved in the disruption of the GEJ in patients with gastroesophageal reflux (GER) symptoms; b) the relationship between the type of GEJ and GER demonstrated by 24 hours pH-monitoring; and c) identification of the alterations in the manometric parameters related to the morphology of the GEJ. METHODS: One hundred and fifteen patients with symptoms of GER studied with HRM and classified by the type of GEJ (type I: Normal; type II: Sliding; type III: Hiatal hernia). Twenty four hour pH-monitoring without proton pump inhibitors was performed in all of them. Epidemiological aspects, manometric parameters (Chicago 2012 classification) and the pH-monitoring results were evaluated. RESULTS: Age (OR 1.033 [1.006-1.060]; p = 0.16), BMI (OR 1.097 [1.022-1.176]; p = 0. 01) and abdominal perimeter (OR 1.034 [1.005-1.063]; p = 0.0215) were independent risk factors for the GEJ type III (area under the curve 0.70). Disruption of the GEJ was associated with a lower resting pressure (p = 0.006), greater length (p < 0.001) and greater esophageal shortening (p < 0.001). Abnormal acidic reflux was found in the total period (p = 0.015), standing (p = 0.022) and supine (p = 0.001) in patients with GEJ type II and III with respect to type I. CONCLUSIONS: Increased age, overweight and central obesity pose a higher risk of GEJ type III (hiatal hernia). The greater disruption of the GEJ is associated with lower resting pressure, esophageal shortening, and higher acid exposure in the pH-monitoring.

BACKGROUND/AIMS: The body position can influence esophageal motility data obtained with high-resolution manometry (HRM). To examine whether the body position influences HRM diagnoses in patients with esophageal dysphagia and gastroesophageal reflux disease (GERD). METHODS: HRM (Manoscan) was performed in 99 patients in the sitting and supine positions; 49 had dysphagia and 50 had GERD as-sessed by 24-hour pH monitoring. HRM plots were analyzed according to the Chicago classification. RESULTS: HRM results varied in the final diagnoses of the esophageal body (EB) in patients with dysphagia (P = 0.024), the result being more distal spasm and weak peristalsis while sitting. In patients with GERD, the HRM diagnoses of the lower esophageal sphinc-ter (LES), the esophagogastric junction (EGJ) morphology, and EB varied depending on the position; (P = 0.063, P = 0.017, P = 0.041 respectively). Hypotensive LES, EGJ type III (hiatal hernia), and weak peristalsis were more frequently identified in the sitting position. The reliability (kappa) of the position influencing HRM diagnoses was similar in dysphagia and GERD ("LES diagnosis": dysphagia 0.32 [0.14-0.49] and GERD 0.31 [0.10-0.52], P = 0.960; "EB diagnosis": dysphagia 0.49 [0.30-0.69] and GERD 0.39 [0.20-0.59], P = 0.480). The reliability in "EGJ morphology" studies was higher in dysphagia 0.81 (0.68-0.94) than in GERD 0.55 (0.37-0.73), P = 0.020. CONCLUSIONS: HRM results varied according to the position in patients with dysphagia and GERD. Weak peristalsis was more frequently diagnosed while sitting in dysphagia and GERD. Hypotensive LES and EGJ type III (hiatal hernia) were also more frequently diagnosed in the sitting position in patients with GERD.

Los divertículos esofágicos (DE) constituyen una patología poco frecuente siendo en su mayoría asintomáticos. Cuando ocasionan síntomas, la disfagia suele ser el más frecuente como consecuencia del tamaño del divertículo y de las alteraciones de la motilidad concomitantes. La manometría de alta resolución (MAR) permite diagnosticar con mayor precisión los trastornos motores subyacentes que se asocian con los DE y comprender su mecanismo fisiopatogénico. Se presentan seis pacientes con disfagia que fueron diagnosticados de DE asociado a un trastorno motor esofágico en la MAR

Introducción: la manometría de alta resolución (MAR) constituye un gran avance en el estudio morfológico de la unión gastroesofágica (UGE) y en sus grados de disrupción. Objetivos: a) valoración factores de riesgo implicados en la disrupción de la UGE en pacientes con síntomas de reflujo gastroesofágico (RGE); b) la relación entre el tipo de UGE y RGE demostrado por pH-metría; y c) identificación de las alteraciones en los parámetros manométricos vinculados a la morfología de la UGE. Métodos: 115 pacientes con síntomas de RGE, estudiados con MAR y clasificados por el tipo de UGE (tipo I o normal; tipo II o deslizamiento; tipo III o hernia de hiato). En todos ellos se realizó pH-metría de 24 horas sin inhibidores de la bomba de protones. Se evaluaron aspectos epidemiológicos, parámetros manométricos (clasificación de Chicago 2012) y resultados de la pH-metría. Resultados: la edad (OR 1,033 [1,006-1,060]; p = 0,016), IMC (OR 1,097 [1,022-1,176]; p = 0,01) y perímetro abdominal (OR 1,034 [1,005-1,063]; p = 0,0215) fueron factores de riesgo independientes para la UGE tipo III (área bajo la curva 0,70). La disrupción de la UGE se asoció con una menor presión de reposo (p = 0,006), mayor longitud de la misma (p < 0,001) y mayor acortamiento esofágico (p < 0,001). Se encontró RGE patológico en el periodo total (p = 0,015), en bipedestación (p = 0,022) y supino (p = 0,001) en el canal distal en los pacientes con UGE tipo II y III respecto al tipo I. Conclusiones: la mayor edad, el sobrepeso y la obesidad central suponen mayor riesgo de desarrollar UGE tipo III (hernia de hiato). La mayor disrupción de la UGE se asocia con menor presión de reposo, mayor acortamiento esofágico y mayor exposición ácida en la pH-metría (AU)
