Molecular and Clinical Aspects of Chronic Manifestations in Chagas Disease: A State-of-the-Art Review. Pathogens 2021; 10:pathogens10111493. [PMID: 34832648 PMCID: PMC8619182 DOI: 10.3390/pathogens10111493] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 11/03/2021] [Accepted: 11/08/2021] [Indexed: 12/11/2022] Open
Abstract
Chronic manifestations of Chagas disease present as disabling and life-threatening conditions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mechanisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particularly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

Abstract
Chagas disease is a neglected tropical disease transmitted by the protozoan Trypanosoma cruzi that lately has been highlighted because several outbreaks attributed to oral transmission of the parasite have occurred. These outbreaks are characterized by high mortality rates and massive infections that cannot be related to other types of transmission such as the vectorial route. Oral transmission of Chagas disease has been reported in Brazil, Colombia, Venezuela, Bolivia, Ecuador, Argentina and French Guiana, most of them are massive oral outbreaks caused by the ingestion of beverages and food contaminated with triatomine feces or parasites' reservoirs secretions and considered since 2012 as a foodborne disease. In this review, we present the current status and all available data regarding oral transmission of Chagas disease, highlighting its relevance as a veterinary and medical foodborne zoonosis.

Abstract
PURPOSE To evaluate the outcome of transhiatal esophagectomy without thoracotomy and with preservation of the vagal trunks for the treatment of advanced megaesophagus. METHODS Between March 2006 and September 2017, it was performed 136 transhiatal esophagectomies without thoracotomy by laparoscopy, with preservation of the vagus nerves. All patients were evaluated pre and postoperatively for respiratory and nutritional aspects Post operatively, some surgical aspects were evaluated like radiology and endoscopy of the digestive tract. RESULTS Follow-up for 7 months to 12 years by clinical, radiologic, endoscopic and pH monitoring revealed satisfactory and encouraging outcomes of the procedure. CONCLUSION The laparoscopic transhiatal esophagectomy is a feasible and safe technique with good postoperative outcomes.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
INTRODUCTION The prevalence of cholelithiasis in the general population ranges from 9 to 18%. This prevalence is known to be higher in the presence of parasympathetic nerve damage of the biliary tract either due to surgery (vagotomy) or neuronal destruction (Chagas disease). The objective of this study was to evaluate the association of cholelithiasis and chagasic or idiopathic megaesophagus. METHODS The ultrasound scans of 152 patients with megaesophagus submitted to cardiomyotomy and subtotal esophagectomy surgery were evaluated. The presence of cholelithiasis was compared between chagasic and idiopathic esophagopathy and ultrasound and clinical findings were correlated with age, sex and race. RESULTS A total of 152 cases of megaesophagus, including 137 with chagasic megaesophagus and 15 with idiopathic megaesophagus, were analyzed. The mean age was 56.7 years (45-67) in the 137 patients with chagasic megaesophagus and 35.6 years (27-44) in the 15 cases of idiopathic megaesophagus, with a significant difference between the two groups (p < 0.0001). The group with chagasic megaesophagus consisted of 59 (43%) women and 78 (56.9%) men, while the group with idiopathic megaesophagus consisted of 8 (53.3%) women and 7 (46.6%) men, showing no significant difference between the groups. Of the 137 patients with confirmed chagasic megaesophagus, 39 (28.4%) presented cholelithiasis versus one case (6.6%) in the 15 patients with idiopathic megaesophagus. CONCLUSIONS The prevalence of cholelithiasis is high in patients with chagasic megaesophagus and preoperative ultrasound should be performed routinely in these patients in order to treat both conditions during the same surgical procedure.

Abstract
OBJETIVO: Utilizamos esta pesquisa para estudar e demonstrar que a esofagectomia subtotal através do acesso laparoscópico e transmediastinal para o preparo do estômago, dissecção do esôfago, abdominal e torácico, e cervicotomia esquerda para retirada da peça e anastomose esôfago-gástrica é facultativa e segura no tratamento do megaesôfago avançado. MÉTODOS: Foram realizadas 60 esofagectomias transhiatais por laparoscopia de setembro de 1996 até dezembro de 2006 (10 casos com preservação dos nervos vagos). A idade média dos pacientes foi 56,4 anos (18 - 76) e antes da operação foram submetidos à sorologia para T. cruzi, esofagograma, endoscopia digestiva de alta resolução, eletromanometria, ultrassom de vesícula biliar e pHmetria de 24 horas, avaliação nutricional, fisioterapia respiratória e suporte nutricional através de sonda nasoenteral. As indicações para o tratamento cirúrgico foram: megaesôfago avançado, diagnosticado radiologicamente e manometricamente, recidiva de megaesôfago após operação envolvendo a junção esôfago-gástrica e associação com disfagia acentuada e/ou neoplasia. O acompanhamento foi de 6 a 118 meses. RESULTADOS: Não houve mortalidade, o tempo médio das operações foi de 160 minutos (110 - 325) e houve melhora de todos os parâmetros avaliados. Doze dos 60 pacientes (20%) apresentaram complicações. Ocorreram oito casos de hemopneumotórax (13,34%), três casos de estase gástrica (5%), quatro casos de fístula cervical (6,67%) com resolução clínica e nove casos de disfonia (15%). CONCLUSÃO: Os resultados observados na esofagectomia transhiatal laparoscópica foram satisfatórios. Demonstraram que a técnica é segura e traz excelentes resultados pós-operatórios.

Abstract
Chagas disease is an infectious disease caused by the protozoan Trypanosoma cruzi. The disease mainly affects the nervous system, digestive system and heart. The objective of this review is to revise the literature and summarize the main chronic gastrointestinal manifestations of Chagas disease. The chronic gastrointestinal manifestations of Chagas disease are mainly a result of enteric nervous system impairment caused by T. cruzi infection. The anatomical locations most commonly described to be affected by Chagas disease are salivary glands, esophagus, lower esophageal sphincter, stomach, small intestine, colon, gallbladder and biliary tree. Chagas disease has also been studied in association with Helicobacter pylori infection, interstitial cells of Cajal and the incidence of gastrointestinal cancer.

Abstract
Megaesophagus is the end-stage of achalasia cardiae. It is the result of peristaltic disorders and slow decompensation of the muscular layer of the esophagus. The aim of this article is to detail the diagnostic criteria and surgical management of megaesophagus. Criteria were acute bending of esophagus axis; lack of esophagus peristalsis, and no response to stimulation in the manometric test; and Los Angeles C/D esophagitis in the endoscopic examination. Between 1991 and 2004 seven patients (5 females, 2 males; age, 51-67 years; average age, 59 +/- 8 years) were treated. A bypass made from the pedunculated part of the jejunum connecting the part of esophagus above the narrowing with the praepyloric part of the stomach was made. Access was by an abdominal approach. A jejunum bypass was made in six patients with megaesophagus. A transhiatal esophageal resection was carried out, and in the second stage a supplementary esophagus was made from the right half of the colon on the ileocolic vessels in one patient who had experienced two earlier unsuccessful operations. Symptoms of dysphagia, recurrent inflammation of the respiratory tract, and pain subsided in all patients. Complications were not reported in the postoperative period. All patients survived. Subsequent radiographic and endoscopic examination showed very good outcome. The jejunum bypass gave very good results in the surgical treatment of megaesophagus.

Abstract
Chagas' disease (CD) is highly prevalent in South America. Brazilian surgeons and gastroenterologists gained valuable experience in the treatment of CD esophagopathy (chagasic achalasia) due to the high number of cases treated. The authors reviewed the lessons learned with the treatment of achalasia by different centers experienced in the treatment of Chagas' disease. Preoperative evaluation, endoscopic treatment (forceful dilatation and botulinum toxin injection), Heller's myotomy, esophagectomy, conservative techniques other than myotomy, and reoperations are discussed in the light of personal experiences and review of International and Brazilian literature. Aspects not frequently adopted by North American and European surgeons are emphasized. The review shows that nonadvanced achalasia is frequently treated by Heller's myotomy. Endoscopic treatment is reserved to limited cases. Treatment for end-stage achalasia is not unanimous. Esophagectomy was a popular treatment in advanced disease; however, the morbidity/mortality associated to the procedure made some authors seek different alternatives, such as Heller's myotomy and cardioplasties. Minimally invasive approach to esophageal resection may change this concept, although few centers perform the procedure routinely.

Abstract
PURPOSE The aim of this study was to standardize the methods of sample collection of mucus from the digestive tract and to determine the microbiota in healthy volunteers from Brazil, collecting samples from the mouth, esophagus, stomach, duodenum, jejunum, ileum, colon, and rectum. METHODS Microbiota of selected healthy volunteers from the oral cavity (n=10), the esophagus (n=10), the upper digestive tract (n=20), and the lower digestive tract (n=24) were evaluated through distinct collection methods. Collection methods took into account the different sites, using basic scraping and swabbing techniques, stimulated saliva from the oral cavity, irrigation-aspiration with sterile catheters especially designed for the esophagus, a probe especially designed for upper digestive tract, and a special catheter for the lower digestive tract. RESULTS (i) Mixed microbiota were identified in the oral cavity, predominantly Gram-positive aerobic and anaerobic cocci; (ii) transitional flora mainly in the esophagus; (iii) Veillonella sp, Lactobacillus sp, and Clostridium sp in the stomach and duodenum; (iv) in the jejunum and upper ileum, we observed Bacteroides sp, Proteus sp, and Staphylococcus sp, in addition to Veillonella sp; (v) in the colon, the presence of "nonpathogenic" anaerobic bacteria Veillonella sp (average 10(5) UFC) indicates the existence of a low oxidation-reduction potential environment, which suggests the possibility of adoption of these bacteria as biological markers of total digestive tract health. CONCLUSIONS The collection methods were efficient in obtaining adequate samples from each segment of the total digestive tract to reveal the normal microbiota. These procedures are safe and easily reproducible for microbiological studies.

Abstract
Objetivou-se avaliar as alterações do esfíncter superior esofágico pela eletromanometria em 37 pacientes portadores da forma clínica indeterminada da doença de Chagas. Foram encontrados 18 (48,6%) pacientes portadores de ondas sincrônicas. A média das pressões máximas do esfíncter foi significativamente maior entre os portadores de ondas sincrônicas. Assim, alguns indivíduos portadores da forma indeterminada da doença de Chagas possuem alterações funcionais caracterizadas pelo aumento da pressão do esfíncter superior do esôfago, que podem ser detectadas à eletromanometria.

Abstract
BACKGROUND After cardiomyotomy for the treatment of megaesophagus, recurrence of symptoms occur in up to 15% of the patients, but only some require a reoperation. AIM To evaluate the results of reoperation -- cardioplasty with Roux-en-Y partial gastrectomy, a technique proposed by Serra-Dória. CASUISTIC AND METHODS Twenty patients with achalasia previously treated by cardiomyotomy, were retrospectively studied. The etiology of symptoms recurrence was reflux esophagitis in nine (45.0%) patients, healing of the myotomy in five (25.0%), end staging megaesophagus in five (25.0%) and incomplete myotomy in one (5%). Intra and postoperative complications were analyzed. The patients were studied by clinical (dysphagia, regurgitation, heartburn and weight gain), radiological and endoscopic evaluation, in the pre- and postoperative period. RESULTS Five (25.0%) patients had complications in the immediate postoperative period. No deaths were observed. Dysphagia improved in all the patients. Regurgitation and heartburn almost disappeared in the whole group. Weight was maintained or increased in 64.7% of the patients. Radiological studies showed a decrease in the caliber of the esophagus in 53.0%, while the remaining patients maintained the pre-operative diameter. Endoscopy, performed during the late postoperative period in 17 patients, showed that 6 among the 9 with reflux esophagitis improved; 2 among the 8 with a normal esophagus during the preoperative period, developed esophagitis. CONCLUSIONS The Serra-Dória procedure for the treatment of megaesophagus in patients who had already undergone cardiomyotomy and whose symptoms recurred, presented a low morbidity and no mortality. It offered a significant relief of symptoms with a decrease of the caliber of the esophagus in several patients. The patients also improved with regards to reflux esophagitis. In some cases reflux was still present after surgery. Others with normal esophagus in the preoperative period developed esophagitis.

Abstract
OBJETIVOS: Avaliar as alterações manométricas dos esfíncteres superior (ESE) e inferior do esôfago, bem como a motilidade de seu corpo, em pacientes com a forma indeterminada da Doença de Chagas. MÉTODO: Foram considerados 37 pacientes portadores da Doença de Chagas, assintomáticos, que apresentavam eletrocardiograma, enema opaco e radiografia contrastada do esôfago sem alterações características da doença (forma indeterminada). Estes foram submetidos à eletromanometria do esôfago em que foram analisados dados sobre a pressão dos esfíncteres e ondas peristálticas do corpo do esôfago. RESULTADOS: Detectouse uma diminuição da média da amplitude de contração do corpo do esôfago (p=0,03) nos portadores de ondas sincrônicas quando comparados com os portadores de ondas assincrônicas. A comparação da média das pressões máximas do ESE nos pacientes portadores de ondas sincrônicas foi significativamente maior (p= 0,02) que a média encontrada nos portadores de ondas assincrônicas. CONCLUSÃO: Encontrou-se um elevado número (48,65%) de portadores de ondas sincrônicas em pacientes com a forma indeterminada da Doença de Chagas; notou-se uma redução da média da amplitude da contração do corpo do esôfago em portadores de ondas sincrônicas e observou-se que a média das pressões máximas do ESE é maior nos pacientes com ondas sincrônicas (207,14 mmHg) quando comparada com os portadores de ondas assincrônicas (142,44 mmHg). Dessa forma propomos uma discussão sobre a classificação atual da Doença de Chagas.

Abstract
Impressive progress has been made in reducing the incidence of Chagas disease, or American trypanosomiasis, in many countries in which the illness is endemic. This has been achieved through expanded blood screening programs and low-technology vector control. Despite the progress made in reducing the number of new cases, the burden of disability and mortality in the endemic countries is enormous and will continue to be so for many years since a substantial portion of the 16 to 18 million persons already infected will develop chronic symptomatic Chagas disease. Unfortunately, no progress has been made in developing new drugs for Trypanosoma cruzi infection, and nifurtimox and benznidazole, both of which lack efficacy and often cause severe side effects, remain the only options for treatment.

Abstract
We propose that selective fundoplication during laparoscopic Heller myotomy achieves optimal outcomes. Fundoplication was applied selectively in 21 of 100 patients undergoing laparoscopic Heller myotomy with hiatus hernia, patulous esophageal hiatus, or intraoperative perforation. Dysphagia and heartburn incidence and severity in patients undergoing myotomy with or without fundoplication were compared before and after myotomy. Median follow-up was 19 months and was similar for both groups. Preoperative symptoms were similar for both groups of patients and showed significant improvement following myotomy with or without fundoplication. As well, there were no significant differences in postoperative dysphagia (26% vs. 14%), dysphagia score (1.1 +/- 1.4 vs. 0.8 +/- 1.3), heartburn (21% vs. 27%), or heartburn score (0.9 +/- 1.5 vs. 1.4 +/- 1.6). Overall improvement was seen in 86% of patients undergoing myotomy with fundoplication and in 97% without fundoplication (P = 0.06). Selective application of fundoplication during laparoscopic Heller myotomy promotes optimal outcomes.

Abstract
The purpose of this study was to evaluate the clinical results and to observe endoscopically the distal esophagus in a series of chagasic adults with incipient megaesophagus and normal endoscopic aspect of the mucosa, who underwent forced hydrostatic dilatation of the cardia, 48 h after the procedure. Twenty patients were submitted to a careful specific pattern of forced dilatation, changing forceful and rapid standardized injection of water to slow distension of the balloon until the patient felt pain. The procedure was repeated three times with the same volume and was maintained each time for 5 min, with intervals of about 3 min. The dysphagia was practically immediately controlled and there were no severe complications or mortality in the series. Five patients complained of pyrosis, mild in two of them. The endoscopic examination revealed mucosal edema in 11 patients (55%), hyperemia in nine (45%) and superficial fissures of the mucosa in six (30%), with seven patients (35%) presenting all the signs simultaneously. These observations characterize 'traumatic esophagitis' due to forced dilatation of the cardia as being frequently asymptomatic. Extreme care with the method can produce effective dilatation of the cardia, avoiding severe complications but not some degree of mucosal injuries.

Abstract
Achalasia is an uncommon motility disorder of the esophagus with an uncertain etiology. Considerable debate exists regarding the most effective treatment for long-term relief of symptoms. For decades, pneumatic dilatation has been the primary treatment option, and surgery was reserved for patients who required repeated dilations or for those who were not willing to undergo the risk of perforation associated with dilatation. Recently botulinum toxin injection of the lower esophageal sphincter has been shown to provide substantial short-term relief from dysphagia; however, its effect only lasts for a short period of time. Recently, minimally invasive surgical techniques have been developed to perform a Heller myotomy effectively with an antireflux procedure. This has become a primary treatment option for many patients. We present a review of the outcome of different therapeutic options of achalasia with a special focus on laparoscopic procedures.

Abstract
Foram estudados prospectivamente cinqüenta pacientes com megaesôfago não avançado tratados por cardiomiectomia com fundoplicatura parcial por via laparoscópica, avaliados sob o ponto de vista clínico e funcional. Houve 12% de complicações intra-operatórias, duas complicações pós-operatórias imediatas e um óbito. Não houve conversões ou complicações tardias. Os resultados ótimos e bons somaram 97,9% dos casos. Houve tendência à diminuição radiológica do calibre do esôfago e desaparecimento da esofagite à endoscopia. A eletromanometria mostrou diminuição significativa da pressão média do esfíncter inferior do esôfago após a operação; a pHmetria de 24 horas constatou diminuição da estase esofágica e ausência de refluxo gastro-esofágico no pós-operatório. Não houve diferença entre os resultados do tratamento de pacientes com megaesôfago chagásico e não chagásico. Os pacientes tiveram o benefício da cirurgia laparoscópica de menor dor, rápida realimentação, alta precoce e breve retorno às atividades habituais.

Abstract
Although achalasia is not a common illness in the United States and Europe, there continues to be a need for surgical therapy for treatment. Laparoscopic Heller myotomy and partial fundoplication has, for the most part, replaced open surgery (abdominal or thoracic) as the surgical treatment of choice. In order to perform this procedure well, one must select patients carefully, evaluate them fully, and adhere to the technical principles required to achieve consistently good results.

Abstract
Gastrointestinal dysfunction is a major problem for many patients with chronic Chagas' disease, as are cardiac dysrhythmias and cardiomyopathy. The underlying anatomic abnormality in these patients is a denervation of the gastrointestinal tract. This process of nerve destruction usually develops insidiously over many years, and it is highly variable in terms of its extent in individual patients as well as in the segments of the gastrointestinal tract that are most affected. Megaesophagus is the most common manifestation of gastrointestinal Chagas disease, and mechanical dilation of the esophageal sphincter or surgery in advanced cases usually give satisfactory relief of symptoms. Megacolon, particularly of the sigmoid segment, is also common in patients with chronic T. cruzi infections, and its presence can be complicated by fecal impaction or sigmoid volvulus. Patients with advanced megacolon who have resections of the sigmoid colon and most of the rectum generally do well postoperatively.

Abstract
Infections of the esophagus are unusual in the general population and strongly imply immunodeficiency, although immunocompetent individuals are not exempt. HIV infection is predominant among risk factors for infectious esophagitis. For all immunocompromised patients, the most frequently identified esophageal pathogens are Candida, CMV, and HSV. Peculiar to HIV-infected patients are idiopathic esophageal ulcers as well as unusual bacteria and parasites. Patterns of presentation differ with each infecting organism, and clinical features should be used as a guide in achieving a correct diagnosis. For example, a patient with AIDS presenting with esophageal symptoms and thrush, along with abdominal pain, nausea, vomiting, and fever, is unlikely to resolve all symptoms with empiric antifungal therapy alone. Parsimony of diagnosis does not hold among immunodeficient patients in whom concurrent infections are common. Accurate and timely diagnoses are essential as effective treatments are available for particular etiologies. Finally, among immunocompromised patients, all esophageal symptoms are not necessarily due to an infection, and possible diagnoses of pill esophagitis, acid-peptic injury, or structural and functional abnormalities should not be overlooked.
