Abstract
Background Morbidity and mortality in lung transplant recipients are often triggered by recurrent aspiration events, potentiated by oesophageal and gastric disorders. Previous small studies have shown conflicting associations between oesophageal function and the development of chronic lung allograft dysfunction (CLAD). Herein, we sought to investigate the relationship between oesophageal motility disorders and long-term outcomes in a large retrospective cohort of lung transplant recipients. Methods All lung transplant recipients at the Toronto Lung Transplant Program from 2012 to 2018 with available oesophageal manometry testing within the first 7 months post-transplant were included in this study. Patients were categorised according to the Chicago Classification of oesophageal disorders (v3.0). Associations between oesophageal motility disorders with the development of CLAD and allograft failure (defined as death or re-transplantation) were assessed. Results Of 487 patients, 57 (12%) had oesophagogastric junction outflow obstruction (OGJOO) and 47 (10%) had a disorder of peristalsis (eight major, 39 minor). In a multivariable analysis, OGJOO was associated with an increased risk of CLAD (HR 1.71, 95% CI 1.15-2.55, p=0.008) and allograft failure (HR 1.69, 95% CI 1.13-2.53, p=0.01). Major disorders of peristalsis were associated with an increased risk of CLAD (HR 1.55, 95% CI 1.01-2.37, p=0.04) and allograft failure (HR 3.33, 95% CI 1.53-7.25, p=0.002). Minor disorders of peristalsis were not significantly associated with CLAD or allograft failure. Conclusion Lung transplant recipients with oesophageal stasis characterised by OGJOO or major disorders of peristalsis were at an increased risk of adverse long-term outcomes. These findings will help with risk stratification of lung transplant recipients and personalisation of treatment for aspiration prevention.

Esophageal motility disorders in symptomatic patients and its relation to age. BMC Gastroenterol 2023; 23:69. [PMID: 36906548 PMCID: PMC10007782 DOI: 10.1186/s12876-023-02709-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 03/02/2023] [Indexed: 03/13/2023] Open
Abstract
BACKGROUND Although swallowing disorders can impact individuals of any age, some are unique to the elderly, and others are frequent. Some disorders, such as achalasia, are diagnosed by esophageal manometry studies, which assess lower esophageal sphincter (LES) pressure and relaxation, peristalsis in the esophageal body, and contraction wave characteristics. This research aimed to evaluate esophageal motility dysfunction in symptomatic patients and its relation to age. METHODS Conventional esophageal manometry was performed on 385 symptomatic patients who were divided into two groups; Group A (age < 65 years old) and Group B (age ≥ 65 years). The geriatric assessment for Group B included cognitive, functional, and clinical frailty scales (CFS). Additionally, a nutritional assessment was done for all patients. RESULTS About one-third of the patients (33%) had achalasia, in which manometric results were significantly higher in Group B (43.4%) than in Group A (28.7%) (P = 0.016). The resting lower esophageal sphincter (LES) pressure, as determined by manometry examination, was significantly lower in Group A than in Group B. In contrast, complete LES relaxation percentage and normal esophageal body peristalsis were significantly higher in Group A than in Group B. Patients who exhibited evidence of achalasia in the manometric study had a significantly increased risk of established malnutrition and functional impairment. CONCLUSIONS Achalasia is a prevalent cause of dysphagia in elderly patients, placing them at risk of malnutrition and functional impairment. Thus, a multidisciplinary approach is vital when providing care for this population.

Abstract
BACKGROUND With the appearance of enhancing high-resolution manometry (HRM), realizing the difference of achalasia symptoms between classified groups by HRM is an outcome of interest in areas with remote access to this device. METHODS All patients newly diagnosed with achalasia from January 2019 to March 2020 were enrolled in the study. All the patients were diagnosed via HRM after undergoing endoscopy to rule out pseudo-achalasia, and grouped based on the Chicago classification criteria and answered a questionnaire assessing relevant symptoms. RESULTS We included 62 patients recently diagnosed with achalasia with a mean age of 53.66 in males (n=30), and 45.4 in females (n=32). Mean time of diagnosis was 24 months. Thirty-seven percent were in type I, 50% in type II, and 13% in type III. Dysphagia and weight loss were higher in type III, while all other relevant symptoms were higher in type II, none of which, however, was statistically significant. Weight loss was reversely associated with duration of symptoms (Spearman correlation= -0.3, P=0.01), and this reverse association was more prominent in females (Spearman correlation= -0.47, P=0.009), type III (Spearman correlation= -0.74, P=0.03), and in the first clinical stages (Spearman correlation= -0.55, P=0.04) in sub analysis. CONCLUSION Type II is the most common type of achalasia in this study. Unlike HRM classification, clinical manifestations alone cannot be used to group patients into different types. However, significant weight loss of the newly diagnosed subjects can become an indicator of on-time diagnosis of the patients.

Abstract
Background Studies have found possible physiologic changes to esophageal motility with aging currently not taken into account in routine high-resolution manometry (HRM) interpretation. We aimed to quantify the relationship between these physiologic changes and aging to improve HRM interpretation. Methods We conducted a retrospective analysis of patients who underwent HRM at a tertiary hospital center between 2015 and 2019. Inclusion criteria were patients aged ≥18 years with normal HRM. Exclusion criteria were abnormal HRM, abnormal upper digestive endoscopy or imagery. Outcomes were median integrated relaxation pressure (IRP), lower esophageal sphincter (LES) pressure, distal contractal integral (DCI), distal latency (DL), and peristaltic break (PB) according to the v4.0 Chicago classification criteria. Effect of age was examined through univariate and multivariate linear regression analysis. Results We identified 1,917 patients with HRM and included 722 patients with normal exams (median age 56 years (interquartile range (IQR) 46 - 66), 63.8% female). Indications for HRM included dysphagia (39.6%), gastroesophageal reflux disease (29.5%), and chest pain (11.5%). There was statistically significant relationship between age and IRP (r = 0.20, P < 0.0001) as well as DCI (r = 0.12, P = 0.001) and DL (r = -0.09, P = 0.02). No statistically significant relationship was found between age and LES pressure or PB. Conclusion We found that IRP, DCI, and to a lesser extent, DL, are significantly correlated with the normal aging process in symptomatic patients. These findings should be taken into consideration when interpreting esophageal HRM.

Abstract
INTRODUCTION AND AIMS Since the 1960s, several studies have shown the effect of aging on esophageal motility, with inconsistent results. The aim of the present study was to evaluate the manometric results in older adult patients (=60 years of age) with an esophageal disorder and compare them with adults under 60 years of age. MATERIALS AND METHODS A cross-sectional, retrospective study was conducted that included a sample of 1,175 patients (936 older adults and 239 non-older adults). The patients were evaluated and compared with respect to (i) sex, (ii) main complaint for which esophageal manometry was indicated, (iii) comorbidities, (iv) current medications, (v) smoking, and (vi) manometry results. RESULTS Patient age ranged from 19 to 92 years (women made up 76.5% of the older adults and 72.8% of the non-older adults). Normal lower esophageal sphincter relaxation and normal peristalsis were more frequent in the non-older patient group (91.1% vs. 84.8% and 87.4% vs. 76%, respectively). The manometry results for the non-older adults vs. the older adults, respectively, were: achalasia (2.9% vs. 5.9%); hypercontractile disorder (9.2% vs. 10.4%); hypocontractile disorder (38.5% vs. 47.6%); and normal values (49.4% vs. 36.1%). After excluding the variables that could change esophageal motility, the results revealed significant differences between the two study groups. CONCLUSIONS Esophageal manometry demonstrated statistically significant differences between the older adult and non-older adult study population evaluated.

Abstract
We undertook a systematic review of swallowing biomechanics, as assessed using pharyngeal and esophageal manometry in healthy or dysphagic older individuals aged over 60 years of age, comparing findings to studies of younger participants. PRISMA-P methodology was used to identify, select, and evaluate eligible studies. Across studies, older participants had lower upper esophageal sphincter (UES) resting pressures and evidence of decreased UES relaxation when compared to younger groups. Intrabolus pressures (IBP) above the UES were increased, demonstrating flow resistance at the UES. Pharyngeal contractility was increased and prolonged in some studies, which may be considered as an attempt to compensate for UES flow resistance. Esophageal studies show evidence of reduced contractile amplitudes in the distal esophagus, and an increased frequency of failed peristaltic events, in concert with reduced lower esophageal sphincter relaxation, in the oldest subjects. Major motility disorders occurred in similar proportions in older and young patients in most clinical studies, but some studies show increases in achalasia or spastic motility in older dysphagia and noncardiac chest pain patients. Overall, study qualities were moderate with a low likelihood of bias. There were few clinical studies specifically focused on swallowing outcomes in older patient groups and more such studies are needed.

Abstract
The aging-associated cellular and molecular changes in esophagus have not been established, yet. Thus we evaluated histological structure, interstitial cells of Cajal (ICCs), neuronal nitric oxide synthase (nNOS)-positive cells, and contractility in the esophagus of Fischer 344 rat at different ages (6-, 31-, 74-weeks, and 2-years). The lamina propria thickness and endomysial area were calculated. The immunoreactivity of c-Kit, nNOS and protein gene product (PGP) 9.5 was counted after immunohistochemistry. Expression of c-Kit, stem cell factor (SCF), nNOS and PGP 9.5 mRNA was measured by real-time PCR, and expression of c-Kit and nNOS protein was detected by Western blot. Isovolumetric contractile force measurement and electrical field stimulation (EFS) were conducted. The lamina propria thickness increased (6 week vs 2 year, P = 0.005) and the endomysial area of longitudinal muscle decreased with aging (6 week vs 2 year, P<0.001), while endomysial area of circular muscle did not significantly decrease. The proportions of NOS-immunoreactive cells and c-Kit-immunoreactive areas declined with aging (6 week vs 2 year; P<0.001 and P = 0.004, respectively), but there was no significant change of PGP 9.5-immunopositiviy. The expressions of nNOS, c-Kit and SCF mRNA also reduced with aging (6 week vs 2 year; P = 0.006, P = 0.001 and P = 0.006, respectively), while the change of PGP 9.5 mRNA expression was not significant. Western blot showed the significant decreases of nNOS and c-Kit protein expression with aging (6 week vs 2 year; P = 0.008 and P = 0.012, respectively). The EFS-induced esophageal contractions significantly decreased in 2-yr-old rat compared with 6-wk-old rats, however, L-NG-Nitroarginine methylester did not significantly increase the spontaneous and EFS-induced contractions in the 6-wk- and 2-yr-old rat esophagus. In conclusion, an increase of lamina propria thickness, a decrease of endomysial area, c-Kit, SCF and NOS expression with preserved total enteric neurons, and contractility in aged rat esophagus may explain the aging-associated esophageal dysmotility.

Abstract
Background/Aims Disturbances of esophageal motility have been reported to be more frequent the aged population. However, the physiology of disturbances in esophageal motility during aging is unclear. The aim of this study was to evaluate the effects of age on esophageal motility using high-resolution esophageal impedance manometry (HRIM). Methods Esophageal motor function of 268 subjects were measured using HRIM in 3 age groups, < 40 years (Group A, n = 32), 40–65 years (Group B, n = 185), and > 65 years (Group C, n = 62). Lower esophageal sphincter (LES) and upper esophageal sphincter (UES) pressures, integrated relaxation pressure, distal contractile integral, contractile front velocity, distal latency, and pressures and duration of contraction on 4 positions along the esophagus, and complete bolus transit were measured. Results Basal UES pressure was lower in Group C (P < 0.001) but there was no significant difference in the LES pressure among groups. Contractile duration on position 3 (10 cm from proximal LES high pressure zone) was longer in Group C (P = 0.001), and the contractile amplitude on position 4 (5 cm from proximal LES high pressure zone) was lower in Group C (P = 0.005). Distal contractile integral was lower in Group C (P = 0.037). Contractile front velocity (P = 0.015) and the onset velocity (P = 0.040) was lower in Group C. There was no significant difference in impedance values. Conclusions The decrease of UES pressure, distal esophageal motility, and peristaltic velocity might be related with esophageal symptoms in the aged population.

Abstract
AIM To investigate the functional effects of abnormal esophagogastric (EGJ) measurements in asymptomatic healthy volunteers over eighty years of age.
METHODS Data from 30 young controls (11 M, mean age 37 ± 11 years) and 15 aged subjects (9 M, 85 ± 4 years) were compared for novel metrics of EGJ-function: EGJ-contractile integral (EGJ-CI), “total” EGJ-CI and bolus flow time (BFT). Data were acquired using a 3.2 mm, 25 pressure (1 cm spacing) and 12 impedance segment (2 cm) solid-state catheter (Unisensor and MMS Solar GI system) across the EGJ. Five swallows each of 5 mL liquid (L) and viscous (V) bolus were analyzed. Mean values were compared using Student’s t test for normally distributed data or Mann Whitney U-test when non-normally distributed. A P value < 0.05 was considered significant.
RESULTS EGJ-CI at rest was similar for older subjects compared to controls. “Total” EGJ-CI, measured during liquid swallowing, was increased in older individuals when compared to young controls (O 39 ± 7 mmHg.cm vs C 18 ± 3 mmHg.cm; P = 0.006). For both liquid and viscous bolus consistencies, IRP4 was increased (L: 11.9 ± 2.3 mmHg vs 5.9 ± 1.0 mmHg, P = 0.019 and V: 14.3 ± 2.4 mmHg vs 7.3 ± 0.8 mmHg; P = 0.02) and BFT was reduced (L: 1.7 ± 0.3 s vs 3.8 ± 0.2 s and V: 1.9 ± 0.3 s vs 3.8 ± 0.2 s; P < 0.001 for both) in older subjects, when compared to young. A matrix of bolus flow and presence above the EGJ indicated reductions in bolus flow at the EGJ occurred due to both impaired bolus transport through the esophageal body (i.e., the bolus never reached the EGJ) and increased flow resistance at the EGJ (i.e., the bolus retained just above the EGJ).
CONCLUSION Bolus flow through the EGJ is reduced in asymptomatic older individuals. Both ineffective esophageal bolus transport and increased EGJ resistance contribute to impaired bolus flow.

[PMID: 27266979 DOI: 10.1016/j.cgh.2016.05.036] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 05/05/2016] [Accepted: 05/25/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Achalasia is a disorder of esophageal motility with a reported incidence of 0.5 to 1.6 per 100,000 persons per year in Europe, Asia, Canada, and America. However, estimates of incidence values have been derived predominantly from retrospective searches of databases of hospital discharge codes and personal communications with gastroenterologists, and are likely to be incorrect. We performed a cohort study based on esophageal manometry findings to determine the incidence of achalasia in South Australia. METHODS We collected data from the Australian Bureau of Statistics on the South Australian population. Cases of achalasia diagnosed by esophageal manometry were identified from the 3 adult manometry laboratory databases in South Australia. Endoscopy reports and case notes were reviewed for correlations with diagnoses. The annual incidence of achalasia in the South Australian population was calculated for the decade 2004 to 2013. Findings were standardized to those of the European Standard Population based on age. RESULTS The annual incidence of achalasia in South Australia ranged from 2.3 to 2.8 per 100,000 persons. The mean age at diagnosis was 62.1 ± 18.1 years. The incidence of achalasia increased with age (Spearman rho, 0.95; P < .01). The age-standardized incidence ranged from 2.1 (95% CI, 1.8-2.3) to 2.5 (95% CI, 2.2-2.7). CONCLUSIONS Based on a cohort study of esophageal manometry, we determined the incidence of achalasia in South Australia to be 2.3 to 2.8 per 100,000 persons and to increase with age. South Australia's relative geographic isolation and the population's access to manometry allowed for more accurate identification of cases than hospital code analyses, with a low probability of missed cases.

Abstract
BACKGROUND AND AIM Esophageal motility disorders (EMDs) affect coordinated esophageal contractility. Recent developments in high-resolution manometry have improved diagnosis of EMDs; however, the etiology of EMDs remains to be determined. This study aimed to determine which clinical characteristics are associated with esophageal motility. METHODS From May 2013 to July 2014, 97 patients (54 women, 43 men; age, 16-89 years) with suspected EMDs were assessed by high-resolution manometry in Kyushu University Hospital. Esophageal motility was evaluated by measuring the distal contractile integral (DCI), basal lower esophageal sphincter pressure, and integrated relaxation pressure (IRP). Data on age, gender, body mass index (BMI), Brinkman Index, and blood tests were retrospectively collected and analyzed. RESULTS Fifty patients were diagnosed as normal, nine with achalasia, twelve with esophagogastric junction outflow obstruction, four with distal esophageal spasm, one with jackhammer esophagus, six with absent peristalsis, ten with frequent failed peristalsis, and five with weak peristalsis. The median DCI was 1229.0 mmHg-s-cm, the median basal lower esophageal sphincter pressure was 25.3 mmHg, and the median IRP was 9.6 mmHg. Patients with major motility disorders were excluded from analysis. By multivariate regression analysis, BMI (P = 0.029) and total cholesterol (P = 0.023) were negatively associated with DCI, while BMI (P = 0.007) was negatively associated with IRP and glucose (P = 0.044) was positively associated with IRP. CONCLUSIONS Both BMI and total cholesterol could be highly predictive factors for esophageal body contractility, while BMI and glucose could be predictive factors for lower esophageal sphincter contractile function.

Abstract
BACKGROUND Human studies have demonstrated aging-related changes in esophagus which may contribute to the increased rate of gastro-esophageal reflux in elderly. The aim of this study was to investigate esophageal morphometric and biomechanical remodeling in aging rats to obtain detailed information about aging-related changes. METHODS Twenty-four male Wistar rats, aged from 6 to 22 months, were studied. Morphometric data were obtained by measuring the wall thickness and cross-sectional area. The esophageal diameter and length were obtained from digitized images of the segments at preselected luminal pressure levels and at no-load and zero-stress states. Circumferential and longitudinal stresses (force per area) and strains (deformation) were computed from the length, diameter and pressure data, and from the zero-stress state geometry. KEY RESULTS The esophageal parameters such as the weight per unit length, the wall thickness and the wall cross-sectional area increased slightly from 6 to 22 months (p < 0.05 to p < 0.001). The opening angle gradually decreased during aging (p < 0.05). The interface between the mucosa-submucosa and muscle layers slightly moved outwards and the neutral axis moved inwards during aging. The stress-strain data showed that the esophageal wall became stiffer circumferentially and longitudinally during aging (p < 0.05, p < 0.01). However, the circumferential wall stiffness showed no further change after 12 months. CONCLUSIONS & INFERENCES A pronounced morphometric and biomechanical remodeling occurred in the rat esophagus during aging.

Abstract
BACKGROUND High-resolution manometry using the Chicago classification, which utilizes parameters including integrated relaxation pressure (IRP), distal contractile integral (DCI), and contractile front velocity (CFV), shows better diagnostic ability than previous conventional criteria. However, the current normal cut-off values for the Chicago classification are based on individuals aged 19-48 years and do not include older people. Here, we aimed to assess the normal values for the Chicago classification in individuals aged 20-67 years and compare the parameters across age groups. METHODS Fifty-four asymptomatic healthy individuals (27 male and 27 female; age range. 20-67 years) were prospectively enrolled. To evaluate the effect of age and sex on manometric profiles, we attempted to enroll equal numbers of male and female subjects for each decade. Manometry was performed in both the supine and sitting positions. KEY RESULTS The distal latency (DL) was significantly shorter with increasing age in both measurement positions. Furthermore, IRP was significantly higher with increasing age in both positions. Spearman's ranked correlation coefficient analysis indicated that DCI and IRP in both positions were positively correlated with age. CONCLUSIONS & INFERENCES Age affects the key parameters currently used in the Chicago classification, including IRP, DCI, and DL. Larger prospective studies with older subjects are needed to determine the age-related normal values for the Chicago classification system.

Abstract
BACKGROUND This study aimed to investigate the relationship between obesity and chronic laryngitis in South Korea using data from the Korea National Health and Nutrition Examination Surveys (KNHANES) collected during 2008-2010. METHODS KNHANES was a cross-sectional survey of the civilian, non-institutionalized population of South Korea (n = 13,819). Obesity status was measured by using BMI and waist circumference. RESULTS Among the population over 19 years of age, the prevalence of chronic laryngitis was 4.0 ± 0.4%. Chronic laryngitis was significantly associated with age, BMI, waist circumference, fat proportion, both systolic and diastolic blood pressure, fasting blood sugar, triglycerides, and high-density lipoprotein cholesterol in women. Old age and current smoking were significantly associated with chronic laryngitis in men. Obese women were at a higher risk for chronic laryngitis than women without obesity (odds ratio (OR) 2.022, 95% confidence interval (95% CI) 1.412-2.895) after further adjustment for confounders. Women with abdominal obesity were also at higher risk for chronic laryngitis (OR 1.475, 95% CI 1.024-2.126). CONCLUSION Obese women in Korea have an elevated risk for developing chronic laryngitis. Further epidemiological and experimental studies are necessary to clarify the impact of obesity on this condition.

Abstract
PURPOSE OF REVIEW This article will review the recent publications (over the last 1-2 years) concerning the effects of ageing on gastrointestinal function, with an emphasis on the motor and sensory function of the gut. RECENT FINDINGS Recent publications support earlier observations of an age-related selective decline in the number of cholinergic neurons in the enteric nervous system, but also reveal a progressive loss of interstitial cells of Cajal in the stomach and colon throughout adult life. These changes appear to have surprisingly little effect on gastrointestinal motor function in healthy ageing, although gut sensation is impaired and older individuals have an increased susceptibility to gastrointestinal complications of comorbid illnesses. SUMMARY Alterations in gut function with ageing have particular implications in the oesophagus, colon, and anorectum. Dysphagia, gastro-oesophageal reflux disease, constipation, and faecal incontinence are the most prevalent clinical manifestations. Older individuals are also susceptible to postprandial hypotension, in which altered cardiovascular responses to intestinal nutrient exposure are pivotal. Dysphagia, delayed gastric emptying, and constipation are increasingly being recognized as early features of Parkinson's disease, and frequently precede the neurological manifestations.
