Number of bottles of esophageal biopsies in the evaluation of eosinophilic esophagitis and clinical outcomes.

BACKGROUND: The number of bottles of esophageal biopsies needed for the evaluation of eosinophilic esophagitis (EoE) is unclear, despite cost differences. AIMS: Assess the clinical outcomes between patients with one and two bottles of esophageal biopsies for the assessment of EoE. METHODS: Retrospective study of adults who underwent esophagogastroduodenoscopy (EGD) for esophageal symptoms between January 2015 and June 2021 and findings of ≥15 eosinophils per high power field (eos/hpf). Patients with one bottle (1 bottle-EoE) had biopsies from the entire or proximal esophagus. Patients with two bottles had biopsies separated from the distal and proximal esophagus and were separated into those with ≥ 15 eos/hpf in both bottles (2 bottle Dif-EoE), or the distal bottle alone (2 bottle Lim-EoE). The primary outcomes were endoscopic findings at follow-up EGD as assessed by the Eosinophilic Esophagitis Endoscopic Reference Score (EREFS) and the presence of ≥15 eos/hpf. RESULTS: Of 85 patients with esophageal eosinophilia who met inclusion criteria, 49 had 2 bottle Dif-EoE, 18 had 2 bottle Lim-EoE, and 18 had 1 bottle-EoE. At median follow-up of 3.3-5.6 months, more patients with 1 bottle EoE had dysphagia (p = 0.029), however there were no differences in the EREFS (p = 0.14) or presence of ≥15 eos/hpf (p = 0.39). More patients with 2 bottle Dif-EoE were treated with topical steroids (16.3% vs. 0% vs. 0%, p = 0.039) and diet (20.4% vs. 0% vs. 5.6%, p = 0.05). CONCLUSION: Endoscopic and histologic outcomes were similar in patients who had one and two bottles for esophageal biopsies in the evaluation of EoE.

Burn Pits: A Possible Trigger for Achalasia.

A 45-year-old female veteran of the United States Air Force (USAF), who was exposed to burn pits on multiple occasions while deployed in the Middle East, presented for a second opinion regarding ongoing chest pain and regurgitation after a Heller myotomy for achalasia. An esophageal X-ray showed no meaningful peristalsis, a slight diverticulum in the distal esophagus, and easy passage of liquids through the lower esophageal sphincter (LES). Esophageal manometry findings were consistent with type 3 achalasia. Based on these and endoscopic evaluation, the prior surgical intervention appeared to be successful for lower esophageal sphincter disruption, so symptoms were managed medically with a proton pump inhibitor, trazodone, and a long-acting nitrate resulting in 70% improvement. We present this case because the patient developed achalasia with a notable history of exposure to open-air burn pits during her military service. While we acknowledge that causality cannot be proven, our case is the first we are aware of that shows a temporal association between burn pit exposure and achalasia. In August of 2022, the United States Congress passed the Promise to Address Comprehensive Toxics (PACT) Act, which expanded the healthcare benefits of veterans exposed to burn pits, making identification of associated conditions a relevant and important endeavor.

Association Between Coronavirus Disease 2019 and Acute Complicated Diverticulitis.

Background Gastrointestinal manifestations of coronavirus disease 2019 (COVID-19) are increasingly recognized. Through potentially overlapping pathophysiology, co-occurrence of COVID-19 and first-time acute diverticulitis has been reported. Our study aims to further characterize this association in COVID-19-positive patients within a large tertiary care academic center. Methodology Patients diagnosed with COVID-19 who subsequently developed acute diverticulitis within 30 days were identified between 2020 and 2022. COVID-19 and acute diverticulitis were diagnosed by polymerase chain reaction and computed tomography, respectively. Patients with prior history of acute diverticulitis were excluded. Patient characteristics and comorbid conditions were collected. Characterization of the COVID-19 course (treatment setting, medical/ventilatory therapy) and acute diverticulitis (treatment setting, medical/surgical therapy, complications) was performed retrospectively. Subanalysis was performed by COVID-19 vaccination status, the severity of COVID-19, and the timing of acute diverticulitis diagnosis. Results A total of 81 patients were identified, with a median duration between COVID-19 diagnosis and acute diverticulitis of 13 days (interquartile range = 2.5-21.0), with 44.4% of patients requiring hospitalization for COVID-19. The all-cause complication rate of acute diverticulitis was noted to be 59.3%, most commonly intestinal perforation (39.5%), abscess formation (37.0%), and peritonitis (14.8%). Although a trend toward increased all-cause complications (65.9%), intestinal perforation (43.9%), and peritonitis (19.5%) was noted in unvaccinated patients, this did not reach significance. Although all-cause complication rate did not differ in patients diagnosed with acute diverticulitis at the time of COVID-19 presentation, a significantly elevated incidence of intestinal perforation (55.9% vs. 27.7%, p = 0.01), peritonitis (29.4% vs. 4.3%, p < 0.01), and the need for emergent surgical intervention (38.2% vs. 10.6%, p < 0.01) was noted. Conclusions Our study indicates that patients diagnosed with first-time acute diverticulitis within 30 days of COVID-19 infection have a high complication rate, most commonly intestinal perforation. Additionally, patients diagnosed with acute diverticulitis at the same time as COVID-19 detection had a significantly elevated rate of complications and emergent surgical needs. Given the high complication rate, patients who develop diverticulitis within a short timeframe of COVID-19 infection may benefit from increased clinician vigilance and monitoring.

Development of Achalasia in a Patient With Chronic Intestinal Pseudo-Obstruction.

Development of concurrent achalasia and chronic intestinal pseudo-obstruction (CIPO) is rare, although esophageal dysmotility is common in patients with CIPO and may suggest worse clinical outcomes. We present a case of a 63-year-old man with a 15-year history of CIPO who developed postprandial regurgitation, vomiting, and dysphagia and was diagnosed with achalasia through radiographic and endoscopic findings. This is only the third case in the reported literature that involves both conditions. Rather than representing 2 separate disorders, CIPO and achalasia may instead represent neurogenic variants of 1 underlying condition affecting the myenteric plexus.

Creating a Dedicated Pandemic Ambulatory Clinic: Lessons Learned From COVID-19.

BACKGROUND AND OBJECTIVES: COVID-19 is highly infectious and the pandemic requires many adaptations to how we deliver medical care. Early in the pandemic, much of this focus was on hospital and emergency department care delivery models to ensure the safety of non-COVID-19 patients and health care workers. However, providing much needed outpatient assessments for COVID-19 patients during a pandemic is also fraught with challenges. From our review of the literature, best practices for a dedicated pandemic ambulatory outpatient clinic have not previously been described. We present a model for creating a dedicated ambulatory pandemic clinic at our institution for the acute care needs of COVID-19 patients. METHODS: To address the current pandemic, the Mayo Acute Symptoms of COVID-19 Clinic was implemented on April 13, 2020, with the aims of providing a stand-alone location for COVID-19 patients to have acute outpatient evaluations as well as diagnostics. RESULTS: Recognized challenges addressed included consideration of airflow recirculation patterns in standard medical office buildings, optimization of protocols to conserve personal protective equipment (PPE), limiting total exposure time during patient flow, and reducing surfaces and spaces that patients would physically contact. To this end, unique methods of patient scheduling, patient flow process, staff training, and PPE protocols were developed and are explained in detail in this article. CONCLUSION: In the COVID-19 pandemic, as well as inevitably in future pandemics, outpatient medical facilities need to be prepared to care for nonhospitalized and nonemergent pandemic patients. We offer a practical approach that has been successful at our institution, with opportunity for local adaptation based on need and resources.

Extent of eosinophilic esophagitis predicts response to treatment.

Background and study aim The clinical impact of eosinophilic esophagitis (EoE) limited to the distal esophagus (Lim-EE) vs. diffuse involvement (Dif-EE) is unknown. This study compared clinical characteristics and outcomes of Lim-EE vs. Dif-EE. Patients and methods This retrospective, single-center study of patients with EoE between December 2011 and December 2019 evaluated treatment response based on repeated pathology and/or clinical improvement using comparative statistics. Results 479 patients were identified (126 Lim-EE, 353 Dif-EE). Lim-EE patients had a higher incidence of endoscopically identified esophagitis (23.0 % vs. 14.7 %; P  = 0.04), were older (50.8 [SD 16.2] vs. 46.4 [SD 15.3] years; P  = 0.007), and were more likely to present with iron deficiency anemia (5.6 % vs. 1.7 %; P  = 0.05), dyspepsia (15.1 % vs. 8.8 %; P  = 0.06) or for Barrett's surveillance (10.3 % vs. 3.7 %; P  = 0.02). Patients with Dif-EE presented more frequently with dysphagia (57.2 % vs. 45.2 %; P  = 0.02). Both groups had similar proton pump inhibitor (87.2 % vs. 83.3 %; P  = 0.37) and steroid (12.8 % vs. 21.4 %; P  = 0.14) use. Patients with Lim-EE had a better clinicopathologic response (61.5 % vs. 44.8 %; P  = 0.009). On multivariate analysis, EoE extent predicted treatment response with an odds ratio of 1.89 (95 % confidence interval 1.13-3.20; P  = 0.02). However, treatment response based only on repeat biopsy results showed no statistical difference between Lim-EE (52.5 %) and Dif-EE (39.7 %; P  = 0.15). Conclusions Lim-EE may represent a distinct phenotype separate from Dif-EE, with more overlap with gastroesophageal reflux disease and better treatment response.

A case series of eosinophilic esophagitis and primary adrenal insufficiency.

Although previously associated with secondary adrenal insufficiency and other autoimmune diseases, eosinophilic esophagitis has not been described in patients with primary adrenal insufficiency. In this case series, we describe three patients with eosinophilic esophagitis and primary adrenal insufficiency, including two patients with polyglandular autoimmune syndrome type 1. All patients experienced improvement in esophageal symptoms with treatment of eosinophilic esophagitis. The association between eosinophilic esophagitis and primary adrenal insufficiency is unclear, but may include underlying genetic predisposition and/or immune system dysregulation.

Addressing the Challenge of COVID-19: One Health Care Site's Leadership Response to the Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic created an extremely disruptive challenge for health care leaders that required a rapid, dynamic, and innovative response. The purpose of this manuscript is to share the leadership actions and decisions at Mayo Clinic in Florida during the first 6 months of the pandemic (February to July 2020). We note 4 strategies that contributed to an effective response: (1) leverage experience with disaster preparedness and mobilize regional and national networks; (2) use surge models to anticipate and to address supply chain issues as well as practical and financial effects of the pandemic; (3) adapt creatively to establish new safety and procedural protocols in various areas for various populations; and (4) communicate timely information effectively and be the common source of truth. Mayo Clinic in Florida was able to address the surges of patients with COVID-19, to provide ongoing tertiary care, and to restore function within the first 6 months with new, strengthened practices and protocols.

Establishing Mayo Clinic's Coronavirus Disease 2019 Virtual Clinic: A Preliminary Communication.

The coronavirus disease 2019 (COVID-19) pandemic is taking a massive toll on health care systems globally. We developed the COVID-19 virtual clinic (CVC) in conjunction with drive through testing to cope with this situation. There are two arms of the CVC: (1) a screening arm and (2) positive patient arm. Screening is performed over the phone based on the Centers for Disease Control and Prevention screening guideline. Positive patients are followed at regular intervals by video appointments where concerns can be addressed by a provider while also tracking symptom progression. We enrolled 63 positive patients out of 1,153 screened for COVID-19 as of this writing. The CVC continues to address patients' concerns and symptoms in an effort to minimize emergency department and hospital patient volumes, as incidence increases. Drive through testing in conjunction with a virtual clinic allows us to provide high-quality care in an anxious time without consuming excessive personal protective equipment or unnecessarily exposing health care workers. This article could serve as a model to guide other practices to cope with this and future pandemics.

Squamous Cell Carcinoma in Lichen Planus of the Esophagus.

Cancer arising in lichen planus of the esophagus (LPE) is extremely rare. We report 2 elderly female patients with LPE who developed squamous cell carcinoma. Both underwent laparoscopic ischemic gastric preconditioning followed 2 weeks later by 3-field esophagectomy. Final pathological stages were carcinoma in situ and pT3N2, respectively. No adjuvant therapy was given. The patient with in situ cancer has no evidence of recurrence at 24 months. The second patient opted to follow up locally and died 8 months later. LPE should be closely monitored for malignant degeneration. Esophagectomy should be considered when malignancy is detected.
