Prevalence of Different Types of Primary Esophageal Motility Disorders and Their Associated Factors in Patients Referring to Shariati Hospital during 2018-2019. Middle East J Dig Dis 2022; 14:70-76. [PMID: 36619723 PMCID: PMC9489321 DOI: 10.34172/mejdd.2022.258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 12/02/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND: Esophageal motility disorders (EMDs) are common in patients with dysphagia and are effectively diagnosed with high-resolution manometry (HREM). In this study, we aimed to evaluate the prevalence of different types of primary EMDs in patients referred for HREM and to further investigate the factors associated with EMDs. METHODS: In this cross-sectional study, all patients referred to the endoscopy section of Shariati Hospital during 2018-2019 (279 patients) were subjected to HREM and were evaluated according to their diagnosis, and the effect of each factor and each symptom on motility disorders was investigated. RESULTS: 84.5% (235) of the participants were diagnosed with at least one esophageal motility disorder; of them, achalasia was the most common form (52.6%). None of the predictive factors showed a statistically significant correlation with EMDs. However, regarding the symptoms, regurgitation and nocturnal cough were significantly more common in patients with EMD (P=0.001 and 0.009, respectively). CONCLUSION: This study demonstrates the high prevalence of EMDs in patients undergoing manometry. None of the factors studied, such as age, sex, diabetes, hypothyroidism, smoking, and alcohol and opium consumption, had a statistically significant correlation with EMDs.

Frequency and clinical characteristics of special types of achalasia in Japan: A large-scale, multicenter database study. J Gastroenterol Hepatol 2021; 36:2828-2833. [PMID: 34032322 DOI: 10.1111/jgh.15557] [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: 11/07/2020] [Revised: 03/18/2021] [Accepted: 05/23/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIM Achalasia is a rare disease, with an incidence of one in 100 000. Genetic factors and autoimmune involvement have been reported in its etiology, and their involvement is strongly suspected, especially in patients with familial achalasia and those with comorbid hereditary or autoimmune diseases. However, these special types of achalasia are rare, and their frequency and clinical characteristics remain unclear. METHODS This retrospective, multicenter cohort study included Japanese patients with a diagnosis of achalasia, treated between 2010 and 2019 across six tertiary centers in Japan. The frequency and clinical characteristics of special types of achalasia, namely, familial achalasia, achalasia with a comorbid hereditary disease, and achalasia with a comorbid autoimmune disease, were retrospectively investigated using a large-scale multicenter database. RESULTS During the study period, 1115 patients were treated for achalasia at six tertiary centers. Familial achalasia, achalasia with a comorbid hereditary disease, and achalasia with a comorbid autoimmune disease occurred in 7 (0.63%), 11 (0.99%), and 27 (2.4%) patients, respectively. Familial achalasia had a slightly younger age of onset (37.6 ± 12.1 years old) and a higher incidence in male patients (six patients; 85.7%). Down's syndrome was the most common hereditary comorbidity, and thyroid disease was the most common autoimmune comorbidity. CONCLUSIONS We clarified the frequency and clinical characteristics of special types of achalasia. Although special types of achalasia are rare, these comorbidities should be considered when treating patients with achalasia.

Abstract
BACKGROUND Idiopathic achalasia is an uncommon esophageal motor disorder. The disease involves interaction between inflammatory and autoimmune responses. However, the antigens related to the disease are still unknown. AIM To identify the possible antigen targets in muscle biopsies from lower esophageal sphincter (LES) of achalasia patients. METHODS Esophageal biopsies of patients with type I and type II achalasia and esophagogastric junction outflow obstruction (EGJOO) were analyzed. Lower esophageal sphincter muscle biopsy from a Healthy organ Donor (HD) was included as control for two-dimensional gel electrophoresis. Immunoblotting of muscle from LES lysate with sera of type I, type II achalasia, or type III achalasia, sera of EGJOO and sera of healthy subjects (HS) was performed. The target proteins of the serum were identified by mass spectrometry Matrix-assited laser desorption/ionization time-of-flight (MALDI-TOF). KEY RESULTS The proteomic map of muscle from LES tissue lysates of type I, and type II achalasia, EGJOO, and HD were analyzed and divided into three important regions. We found a difference in the concentration of certain spots. Further, we observed the serum reactivity of type I achalasia and type II achalasia against 45 and 25 kDa bands of type I achalasia tissue. Serum of type III achalasia and EGJOO mainly recognized 25 kDa band. Bands correspond to triosephosphate isomerase (TPI) (25 kDa), carbonic anhydrase (CA) (25 kDa) and creatinine kinase-brain (CKB) isoform (45 kDa). CONCLUSIONS AND INFERENCES We identify three antigen targets, TPI, CA, and CKB isoform, which are recognized by sera from patients with achalasia.

Abstract
An 11-year-old, neutered female, Labrador retriever dog was presented with a history of intractable vomiting, regurgitation, and coughing. Computed tomography (CT) imaging identified marked hypertrophy of the distal esophagus with a suspicion of distal esophageal achalasia, based on the observation of a "bird beak" appearance. This was later confirmed on a fluoroscopic swallow study. Marked hypertrophy of the gastric pylorus was also identified on CT imaging, and polypoid gastric mucosal hyperplasia was diagnosed based on the gross endoscopic appearance combined with gastric histopathology. Secondary aspiration pneumonia was diagnosed based on the results of CT imaging, bronchoscopy and bronchoalveolar lavage fluid analysis. Medical therapy alone failed to elicit any significant improvement, but clinical resolution was achieved following surgical intervention comprising Ventral Heller myotomy, Dor's fundoplication, and pyloroplasty.

Abstract
BACKGROUND AND AIM Idiopathic achalasia is a rare esophageal motor disorder. The disease state manifests local and systemic inflammation, and it appears that an autoimmune component and specific autoantibodies participate in the pathogenesis. The study aims to determine the prevalence of autoimmune and chronic inflammatory diseases in patients with achalasia and compare the results with those from patients with gastroesophageal reflux disease (GERD). METHODS It was a cross-sectional and included 114 patients with idiopathic achalasia and 114 age-matched and sex-matched control patients with GERD. Data on the presence of autoimmune and inflammatory diseases, the time of presentation, and any family history of autoimmune disease were obtained from the hospital's medical records. RESULTS Seventy three (64%) were female patients (mean age: 42.3 ± 15.5; median disease duration: 12 months). We identified the presence of autoimmune disease in 19 patients with achalasia (16.7%), hypothyroidism was the main diagnosis, and it was present in 52.6% of patients compared with 4.2% in controls. Thirteen of the 19 achalasia patients (68.4%) with autoimmune disease had history of familial autoimmunity. We identified 11 achalasia (9.6%) and 5 GERD patients (4.16%) with an inflammatory condition. Compared with the GERD, the achalasia group was 3.8 times more likely to have an autoimmune disease (95% CI: 1.47-9.83), 3.0 times more likely to have thyroidopathies (95% CI: 1.00-9.03), and 3.02 times more likely to suffer from any chronic inflammatory disease (95% CI: 1.65-6.20). CONCLUSIONS The non-negligible number of patients with autoimmune diseases identified among the patients with idiopathic achalasia supports the hypothesis that achalasia has an autoimmune component.

Abstract
Idiopathic achalasia is an archetype esophageal motor disorder, causing significant impairment of eating ability and reducing quality of life. The pathophysiological underpinnings of this condition are loss of esophageal peristalsis and insufficient relaxation of the lower esophageal sphincter (LES). The clinical manifestations include dysphagia for both solids and liquids, regurgitation of esophageal contents, retrosternal chest pain, cough, aspiration, weight loss and heartburn. Even though idiopathic achalasia was first described more than 300 years ago, researchers are only now beginning to unravel its complex etiology and molecular pathology. The most recent findings indicate an autoimmune component, as suggested by the presence of circulating anti-myenteric plexus autoantibodies, and a genetic predisposition, as suggested by observed correlations with other well-defined genetic syndromes such as Allgrove syndrome and multiple endocrine neoplasia type 2 B syndrome. Viral agents (herpes, varicella zoster) have also been proposed as causative and promoting factors. Unfortunately, the therapeutic approaches available today do not resolve the causes of the disease, and only target the consequential changes to the involved tissues, such as destruction of the LES, rather than restoring or modifying the underlying pathology. New therapies should aim to stop the disease at early stages, thereby preventing the consequential changes from developing and inhibiting permanent damage. This review focuses on the known characteristics of idiopathic achalasia that will help promote understanding its pathogenesis and improve therapeutic management to positively impact the patient’s quality of life.

Abstract
PURPOSE Gastrointestinal tract is one of the most affected systems in hypothyroidism. Despite decreased esophageal emptying, prolonged esophageal and gastric transit time have been indicated in previous reports, the mechanism of thyroid hormones activity and antibodies on the esophagus motility is not yet fully understood. This study was conducted to evaluate the esophagus motility by manometry in hypothyroid patients. METHODS The study enrolled with 28 overt, newly diagnosed hypothyroid patients and 29 age- and sex-matched healthy controls. Twenty-one females and 7 males with overt hypothyroidism and 22 females and 7 males with healthy control subjects were recruited to study. Esophageal manometry was performed using MMS (Medical Measurement Systems bv. The Netherlands) Solar GI-Air-Charged Intelligent Gastrointestinal Conventional Manometry. RESULTS The lower esophageal sphincter pressure (LESP) was 19.5 ± 6.5 mmHg in hypothyroid patients and 17.48 ± 4.65 mmHg in controls, and there was no significant difference (p = 0.18). Percentage of relaxation was 61.5 and 80.9 %, and it was significantly lower in hypothyroid patients than controls (p < 0.001). Additionally, duration of relaxation was found 3.85 ± 2.3 and 5.5 ± 2.28 s in patients and controls, respectively (p = 0.009). In patient group, LESP was positively correlated with fT3 (p = 0.033), and the duration of the contraction was negatively correlated with fT4 (p = 0.044). CONCLUSION In this study, we observed that hypothyroid state can affect esophagus motility via shortened duration of relaxation and reduced percentage of relaxation even if in patients without any gastrointestinal symptoms. Further studies are needed to clarify the effect of thyroid hormones on esophagus motility.

Abstract
Many cases have been published showing a co-existence of autoimmune thyroid diseases (AITDs) and other autoimmune diseases. About a quarter of patients with achalasia have a concurrent thyroid disease, most commonly associated with hypothyroidism. Although relatively rare, the association of achalasia and hyperthyroidism requires attention. The physiopathology of Grave's Disease (GD) involves B- and T-mediator lymphocytes, which have an affinity for known thyroid antigens: thyroglobulin, thyroid-peroxidase, and thyrotrophin receptor. Currently, however, the real physiopathogenesis of achalasia continues to be unknown. Some important findings are suggestive of an autoimmune mechanism: significant infiltration of the myoenteric plexus by monocytes, presence of the class II-Human Histocompatibility Complex DQwl antigen and antibodies to myoenteric neurons. The present case reports a patient who, despite testing negative for Chagas' disease, had achalasia, progressed to developing significant wasting and worsening of his quality of life, was later diagnosed with hyperthyroidism. After endoscopic esophageal dilatation and radioiodine ablation of the thyroid gland, there was great improvement in the patient clinical condition.

Abstract
Achalasia is a rare disease of the esophagus that has an unknown etiology. Genetic, infectious, and autoimmune mechanisms have each been proposed. Autoimmune diseases often occur in association with one another, either within a single individual or in a family. There have been separate case reports of patients with both achalasia and one or more autoimmune diseases, but no study has yet determined the prevalence of autoimmune diseases in the achalasia population. This paper aims to compare the prevalence of autoimmune disease in patients with esophageal achalasia to the general population. We retrospectively reviewed the charts of 193 achalasia patients who received treatment at Toronto's University Health Network between January 2000 and May 2010 to identify other autoimmune diseases and a number of control conditions. We determined the general population prevalence of autoimmune diseases from published epidemiological studies. The achalasia sample was, on average, 10-15 years older and had slightly more men than the control populations. Compared to the general population, patients with achalasia were 5.4 times more likely to have type I diabetes mellitus (95% confidence interval [CI] 1.5-19), 8.5 times as likely to have hypothyroidism (95% CI 5.0-14), 37 times as likely to have Sjögren's syndrome (95% CI 1.9-205), 43 times as likely to have systemic lupus erythematosus (95% CI 12-154), and 259 times as likely to have uveitis (95% CI 13-1438). Overall, patients with achalasia were 3.6 times more likely to suffer from any autoimmune condition (95% CI 2.5-5.3). Our findings are consistent with the impression that achalasia's etiology has an autoimmune component. Further research is needed to more conclusively define achalasia as an autoimmune disease.

Abstract
BACKGROUND Achalasia is the most recognized motor disorder of the esophagus. Because it is an uncommon disease, most studies have reviewed small numbers of patients. Here, we report demographic, clinical features and treatment outcomes in 700 achalasia patients. METHODS In all patients, diagnosis was established based on clinical, radiological, endoscopic and manometric criteria. A questionnaire was completed for each patient and included the patient's age, gender, initial symptoms, frequency of different symptoms, presence of positive family history for achalasia, other accompanying diseases and treatment outcomes. RESULTS In our study men were affected more than women (54.3% vs. 45.7%). Patients' mean age was about 38 years. The most frequent symptoms noted were: dysphagia to solids and liquids, active regurgitation, passive regurgitation and weight loss, respectively. Women complained of chest pain more than men (59% vs. 47.1%, p=0.04). The vast majority of our patients were treated by pneumatic dilation (PD) of the LES and in long-term follow-up, 67% were in the responder group. Females responded better than males to PD. CONCLUSION Dysphagia to solids is the most common symptom in patients with achalasia. Chest pain was significantly higher among women. PD is an effective treatment for achalasia with long-term efficacy in the majority of patients.

Abstract
Despite increasing understanding of the pathophysiology of achalasia, the etiology of this esophageal motility disorder remains largely unknown. However, the occurrence of familial achalasia and its association with well-defined genetic syndromes suggest the involvement of genetic factors. Mutant mouse models display gastrointestinal disturbances that are similar to those observed in achalasia patients. The candidate gene approach has revealed some promising results; however, it has not established conclusive links to specific genes so far. The aim of this review was to summarize current knowledge of the genetics of achalasia. We also discuss the extent to which our understanding of achalasia is likely to be enhanced through future molecular genetic research.
