Ulceración esofágica por ingestión de doxiciclina / Doxycycline induced esophageal ulceration

La ulceración esofágica por ingestión de doxiciclina es una de las causas más frecuentes de lesión esofágica. Ha sido subdiagnosticada y escasamente reconocida en dermatología. El dolor retroesternal, la odinofagia de aparición brusca y el antecedente de ingesta de doxiciclina u otros fármacos son características que facilitan su diagnóstico. Puede presentar complicaciones serias, como hemorragias, estenosis y mediastinitis.

Esophageal ulceration due to ingestion of doxycycline is one of the most frequent causes of esophageal injury. It has been underdiagnosed and scarcely recognized in dermatology. Retrosternal pain, sudden odynophagia and a history of doxycycline or other drugs intake are some of the characteristics that lead to diagnosis. It may cause severe complications such as bleeding, stenosis and mediastinitis.

Metachronous Esophageal Ulcers after Immune-mediated Colitis Due to Immune Checkpoint Inhibitor Therapy: A Case Report and Literature Review.

Although cases of gastrointestinal toxicity of pembrolizumab have been reported, cases of acute immune-mediated colitis accompanied with metachronous esophageal disorders (esophagitis and ulcer) are rare. We herein report a case of acute colitis and metachronous esophageal ulcers due to an immune-related adverse event following concomitant pembrolizumab chemotherapy for lung adenocarcinoma. To our knowledge, there have so far been no reports of cases in which both acute immune-mediated colitis and metachronous esophageal ulcers developed. We therefore report the details of this case along with a review of the pertinent literature.

Multiple esophageal ulcers due to tofacitinib 10 mg twice daily for ulcerative colitis.

A 26-year-old man was admitted to our institution for ulcerative colitis treatment. He used mesalamine, steroid, immunomodulators, and anti-TNFα anti-body, but it was difficult to maintain remission. We started induction therapy with tofacitinib (TOF) 10 mg twice daily. He maintained clinical remission but had chest pain 44 days after the start of TOF. Esophagogastroduodenoscopy showed multiple ulcers from middle to lower esophagus. Although rare, TOF induced esophageal ulcers were considered based on his clinical course and endoscopic findings.

Opioid-Induced Esophageal Dysfunction: Differential Effects of Type and Dose.

OBJECTIVE: Data regarding opioid effects on esophageal function are limited. We previously demonstrated an association between chronic opioid use and esophageal motor dysfunction characterized by esophagogastric junction outflow obstruction, distal esophageal spasm, achalasia type III, and possibly Jackhammer esophagus. Our aim was to characterize the influence of different opioids and doses on esophageal dysfunction. METHODS: Retrospective review of 225 patients prescribed oxycodone, hydrocodone, or tramadol for >3 months, who completed high-resolution manometry from 2012 to 2017. Demographic and manometric data were extracted from a prospectively maintained motility database. Frequency of opioid-induced esophageal dysfunction (OIED, defined as distal esophageal spasm, esophagogastric junction outflow obstruction, achalasia type III, or Jackhammer esophagus on high-resolution manometry, was compared among different opioids. The total 24-hour opioid doses for oxycodone, hydrocodone, and tramadol were converted to a morphine equivalent for dose effect analysis. RESULTS: OIED was present in 24% (55 of 225) of opioid users. OIED was significantly more prevalent with oxycodone or hydrocodone use compared with tramadol (31% vs 28% vs 12%, P = 0.0162), and for oxycodone alone vs oxycodone with acetaminophen (43% vs 21%, P = 0.0482). There was no difference in OIED for patients taking hydrocodone alone vs hydrocodone with acetaminophen. Patients with OIED were taking a higher median 24-hour opioid dose than those without OIED (45 vs 30 mg, P = 0.058). DISCUSSION: OIED is more prevalent in patients taking oxycodone or hydrocodone compared with tramadol. There is greater likelihood of OIED developing with higher doses. Reducing the opioid dose or changing to tramadol may reduce OIED in opioid users.

Hepatocyte Growth Factor Facilitates Esophageal Mucosal Repair and Inhibits the Submucosal Fibrosis in a Rat Model of Esophageal Ulcer.

BACKGROUND/AIMS: Esophageal mucosal damage often causes scar tissue, leading to refractory stricture. The aim of this study was to clarify the effect of hepatocyte growth factor (HGF) on esophageal mucosal repair and fibrosis leading to stricture in a rat model of esophageal ulcer. METHODS: Esophageal ulcers were induced in rats by topical exposure of the lower esophageal serosa to acetic acid, followed by intraperitoneal administration of HGF (200 µg/day) using an osmotic pump for 7 days. The effect of HGF on esophageal mucosal injury was investigated macroscopically and microscopically. The effect of HGF on epithelial cell proliferation and the expression of genes closely associated with the development of fibrosis were also examined. RESULTS: The administration of HGF for 7 days led to a significant reduction in the ulcerative area and enhanced the proliferation of esophageal epithelial cells. HGF treatment significantly decreased the fibrosis, and subsequently attenuated not only the foreshortening but also the narrowing of the esophagus. The expression levels of tissue inhibitor of metalloproteinase (TIMP)-1, -2, and matrix metalloproteinase (MMP)-2, -9 were significantly decreased among rats treated with HGF. CONCLUSION: HGF facilitates the repair of esophageal mucosal injury and may also ameliorate the esophageal fibrosis, possibly through enhanced re-epithelization.

Oesophageal ulcer due to a herbal remedy.

Herbal-induced oesophageal lesions are rare. We report the case of an 85-year-old male who presented with cough and odynophagia. An upper endoscopy showed white deposit under the proximal oesophageal sphincter. Biopsy of the lesion revealed an oesophageal ulcer with adherent plant material and ruled-out candidiasis. At this point, the patient divulged self-preparation of an herbal remedy consisting of Aloe Vera pulp, whisky, honey, ginger and turmeric. Aloe Vera, ginger and turmeric are commonly used to sooth some gastroenterological symptoms in Complementary and Alternative Medicine. Incorrect extraction of Aloe Vera pulp and adding honey to it transformed the recipe into a sticky paste that may have injured the oesophageal mucosa. Follow-up showed that the cough and odynophagia subsided after discontinuing this herbal remedy.

Pradaxa-induced esophageal ulcer.

Pradaxa (dabigatran) is a direct thrombin inhibitor approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. We describe a case of esophageal ulceration associated with Pradaxa administration in a 75-year-old man. The patient reported difficulty swallowing and a burning sensation after taking his first dose of Pradaxa. An esophagogastroduodenoscopy (EGD) revealed linear ulcerations in the mid-esophagus. Pradaxa was held beginning the day before the EGD. The patient reported that his pain and difficulty swallowing resolved on stopping Pradaxa. Pradaxa is formulated with a tartaric acid excipient to reduce variability in absorption. We hypothesise that the capsule lodged in the patient's esophagus and the tartaric acid may have caused local damage resulting in an esophageal ulcer. It is important to educate patients on proper administration of Pradaxa, to decrease the risk of this rare, but potentially serious adverse event.

Successful treatment with alectinib after crizotinib-induced esophageal ulceration.

Crizotinib was the first clinically available inhibitor of the tyrosine kinase ALK, and next-generation ALK inhibitors, such as alectinib, are now under development. Although crizotinib is generally well tolerated, severe esophageal injury has been reported as a rare but serious adverse event of crizotinib therapy. We now describe the successful treatment with alectinib of a patient who developed crizotinib-induced esophageal ulceration.

[Caustic injury of upper gastrointestinal tract: 20 year experience at a tertiary referral center].

BACKGROUND/AIMS: Caustic ingestion can cause severe injury to upper gastrointestinal tract. There were few studies about clinical characteristics and treatments of caustic injury in Korea. We investigated the changes in clinical features of caustic injury over the past 20 years including pattern of endoscopic mucosal injury and treatment modality. METHODS: This study was a retrospective review of medical records from patients with caustic injury from September 1993 through December 2012. Patients were classified into two groups based on the year when caustic ingestion occurred: patients who visited the hospital from 1993 to 2002 (early group) and patients who visited the hospital from 2003 to 2012 (late group). RESULTS: A total 140 patients were included (early group [n=50] vs. late group [n=90]). Annual number of caustic ingestions did not show decreasing tendency over the past 20 years. Alkali ingestion increased (20.0% vs. 65.6%, p<0.001) and cases with more than grade 2b of esophageal mucosal injury decreased (41.3% vs. 20.7%, p=0.012) in late group. There were no differences between two groups in sex, age, proportion of accidental ingestion, and systemic/gastrointestinal complications. Use of gastric lavage (p<0.01) and broad spectrum antibiotics (p=0.03) decreased in late group. However, there was no difference in use of steroid between two groups. CONCLUSIONS: In this study, overall caustic ingestion did not decrease and ingestion of alkali agents increased over the past 20 years. Tighter legislation on caustic agents is required and we need to be alert to the best management of caustic injury.

Dissecting intramural hematoma of esophagus after thrombolytic therapy: a case report.

Esophageal hematoma is a relatively rare event. We report a case of severe chest pain associated with myocardial infarction and recurrent chest pain after administration of a thrombolytic agent. The chest pain was different from the presenting symptom and accompanied by 2 episodes of hematemesis. Esophageal hematoma was confirmed after endoscopy and computed tomography. Esophageal hematoma is a relatively rare event after thrombolytic therapy.

Should computerised tomography replace endoscopy in the evaluation of symptomatic ingestion of corrosive substances?

INTRODUCTION: Corrosive ingestions are common, although most ingestions do not result in clinically significant effects. Limited guidance is available on the role of endoscopy and/or computerised tomography (CT) in the investigation of individuals with corrosive ingestion, and the present data regarding predictors of poor outcome are confusing. Furthermore, whilst there are many case series describing the use of endoscopy in corrosive ingestions, no clear ideal time frame has been established as to when it should be undertaken. More recently, CT has been used to grade injuries, but there are few studies on its role in managing corrosive injuries, and those studies that have been reported are conflicting in their results. METHODS: A Medline search was performed with the terms 'Caustic ingestion' and 'Corrosive ingestion' and a second search by adding the words 'Endoscopy', 'CT', and 'Computerised tomography' as a subject term or keyword. These searches revealed a total of 277 reviews and papers, of which 33 original papers were relevant for analysis. Three further papers were identified during the analysis of these papers and a PubMed search of the same terms added one further paper, bringing the total to 37. There have been no prospective, randomised controlled trials directly comparing endoscopy and CT. Only two retrospective studies compared the use of CT and that of endoscopy. Thirty-five studies examined whether an endoscopy is always needed, and if so, within what time frame this should be done: CT or endoscopy? A review of these studies suggests that the data regarding the use of CT in these circumstances are not yet of sufficient weight to replace endoscopy as the first-line investigation in corrosive ingestion-related injury. Who needs investigation after corrosive ingestion? We believe that signs and symptoms indicate the likelihood of clinically significant injury in adults. Specifically, any evidence of oropharyngeal burns, drooling, vomiting, pain or dysphagia clearly indicates the need for an endoscopy. In children, it appears that an even greater degree of caution is needed. How soon after ingestion should investigation be performed? For whom an endoscopy is required, it is prudent to enable surgery and other specifics regarding management of corrosives to be decided quickly (< 12 h). There are many incidences where endoscopy has been done safely beyond 48 h although this is not needed frequently. Management recommendations Asymptomatic patients, particularly adults with a normal clinical examination and who can eat and drink normally, can be discharged safely without endoscopy. Endoscopy is preferred over CT in the assessment of risk in symptomatic patients with corrosive ingestion. If patients have any oropharyngeal injury and in particular symptoms of drooling, vomiting, dysphagia or pain (retrosternal or otherwise), the risk of having a high-grade injury is higher, and urgent endoscopy should be performed to grade the injury and determine whether surgical intervention is required. Patients who have non-specific symptoms, such as cough, should also undergo endoscopy, but this is less urgent. CONCLUSIONS: Despite the lack of high-quality clinical trial data, the available evidence and clinical experience support the use of early endoscopy (< 12 h) in patients who are symptomatic after ingestion of a corrosive substance. We propose a clinical guideline that can be used to help plan management of corrosives.
