Clinical, Gender, Socioeconomic Characteristics and Outcomes of Individuals Receiving Hepatitis B Treatment in Ethiopia: 18-Month Follow-Up.

There is a lack of real-world data on hepatitis B (HBV) treatment in Africa. We conducted a single-center 18-month prospective cohort study in Ethiopia to understand clinical, laboratory, and demographic variables associated with HBV treatment. One hundred fifty HBV-positive patients were included: 51 on treatment, 99 with no treatment. Median age was similar between groups. Those on treatment were more likely to be male (86%), report higher coffee intake (90% versus 70%, P < 0.05), lower khat intake (0% versus 9%, P = 0.08), lower alcohol consumption (0% versus 5%, P = 0.1), and had attained higher levels of education (56% versus 42%, P = 0.19). Individuals on treatment had higher median aspartate aminotransferase (AST), alanine aminotransferase (ALT), HBV DNA, and median Aminotransferase-to-Platelet Ratio Index and Fibrosis-4 scores. At 6 and 12 months, those on treatment showed a decrease in median AST, ALT, and fibrosis scores and had less hepatocellular carcinoma development at 6 months (2% versus 4%). Our study highlights potential demographic disparities in HBV treatment as well as benefits in a real-life setting in Africa.

Low Prevalence of Endoscopic Screening for Barrett's Esophagus in a Screening-Eligible Primary Care Population.

INTRODUCTION: Despite societal recommendations supporting Barrett's esophagus (BE) screening, it is unknown what proportion of eligible patients is screened in primary care. We assessed the proportion of BE screening- eligible patients evaluated in the primary care setting receiving upper esophagogastroduodenoscopy (EGD) and identified factors associated with undergoing EGD. METHODS: This was a retrospective study of BE screening-eligible patients, as defined by the American College of Gastroenterology's BE guidelines, in a multipractice healthcare network consisting of 64 internal medicine practices and 94 family medicine (FM) practices. The proportion undergoing EGD, prevalence of BE and esophageal adenocarcinoma (EAC) in this group, and patient and provider factors associated with undergoing EGD were assessed. Multivariable logistic regression was performed to identify independent predictors of undergoing EGD. RESULTS: Of 1,127 screening-eligible patients, the mean age was 65.2 ± 8.6 years; 45% were obese; and 61% were smokers. Seventy-three percent were seeing FM; 94% were on proton pump inhibitors; and 44% took ≥1 gastroesophageal reflux disease (GERD) medication. Only 39% of patients (n = 436) had undergone EGD. The overall prevalence of BE or EAC was 9.9%. Of 39 (9%) referred for BE screening as the primary indication, BE/EAC prevalence was 35.1%. Factors associated with increased odds of having EGD were symptomatic GERD despite treatment (odds ratio [OR] 12.1, 95% confidence interval [CI] 9.1-16.3), being on ≥1 GERD medication (OR 1.4, 95% CI 1.0-1.9), and being an FM patient (OR 1.5, 95% CI 1.1-2.1). DISCUSSION: In this large, primary care population, only 39% of screening-eligible patients underwent EGD. Most of the examinations were triggered by refractory symptoms rather than screening referrals, highlighting a need for improved dissemination and implementation of BE screening.

Loss to Follow-Up and Health Care Utilization After Initial Diagnosis of Eosinophilic Esophagitis.

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic disease, but the extent of patient loss to follow-up (LTFU) and health care utilization has not been fully investigated. AIM: To determine frequency and predictors of LTFU and health care utilization in EoE patients. METHODS: In this retrospective cohort study, we extracted data from patients with a new diagnosis of EoE. Follow-up time for each patient was calculated as the time from the first diagnostic endoscopy to the last GI-related contact date in the medical record. Patients with and without LTFU were compared, and the volume of EoE-related health care interactions was recorded. RESULTS: Of 944 EoE cases, 249 (26%) met the definition for LTFU. Major reasons for LTFU were never being scheduled (45%) and inability to contact patients (40%). Factors independently associated with regular follow-up were having insurance (aOR 2.89; 95% CI 1.85-4.50), white race (aOR 2.16; 95% CI 1.37-3.41), and longer symptom length (aOR 1.04 per year; 95% CI 1.01-1.08). At the time of last contact, patients with follow-up had better symptom response (55% vs. 12%; p < 0.001), improved esophageal caliber (14.3 vs. 12.4 mm; p = 0.005), and more histologic response (45% vs. 4% at 15 eos/hpf; p < 0.001). Health care utilization was high, with an average of 4.6 endoscopies and 4.0 clinic visits over the follow-up period. CONCLUSIONS: LTFU of newly diagnosed EoE cases was common and associated with lack of insurance, non-white race, and shorter symptom duration. Those who followed up had high health care utilization but improved response rates. Strategies are needed to help decrease LTFU in EoE.

Clinical features and time trends associated with an endoscopically normal esophagus in active eosinophilic esophagitis.

BACKGROUND: A proportion of patients with active eosinophilic esophagitis (EoE) have a normal-appearing esophagus on esophagogastroduodenoscopy (EGD). We aimed to determine the associations between the baseline clinical features and the endoscopically normal esophagus in EoE, as well as time trends in reporting. METHODS: In this retrospective study of active EoE cases from 2002 - 2018, patients with and without esophageal endoscopic abnormalities were compared. Multivariable logistic regression identified the independent predictors of a normal EGD. The proportion of patients with a normal EGD was determined per year, and before and after the introduction of the first EoE guidelines and the EoE Endoscopic Reference Score (EREFS). RESULTS: Of 878 EoE patients, 101 (11.5 %) had an endoscopically normal esophagus; they were younger (8.3 vs. 25.4 years), had shorter median symptom duration before diagnosis (2.8 vs. 5.0 years), were less likely to have dysphagia (40 % vs. 76 %) or food impaction (8 % vs. 33 %), and more likely to have abdominal pain (37 % vs. 19 %) (P < 0.01 for all). On multivariable logistic regression, independent predictors of a normal esophagus were younger age (odds ratio [OR] 0.96, 95 % confidence interval [CI] 0.94 - 0.98), abdominal pain (OR 2.03, 95 %CI 1.13 - 3.67), and lack of dysphagia (OR 0.49, 95 %CI 0.26 - 0.93). The proportion of patients with a normal esophagus decreased from 21 % before the first EoE guidelines to 7 % (P < 0.01) after introduction of the EREFS. CONCLUSIONS: An endoscopically normal esophagus is seen in ~10 % of active EoE patients and should not preclude biopsies; younger age, abdominal pain, and lack of dysphagia are independent predictors. The proportion of normal EGDs decreased over time, suggesting improved recognition of endoscopic findings.

Psychiatric Comorbidities and Psychiatric Medication Use Are Highly Prevalent in Patients With Eosinophilic Esophagitis and Associate With Clinical Presentation.

OBJECTIVES: The prevalence of psychiatric disease in patients with eosinophilic esophagitis (EoE) is not fully characterized. We aimed to determine the prevalence of psychiatric disease and centrally acting medication use in a cohort of children and adults with EoE and evaluated whether psychiatric disease affects the EoE clinical presentation. METHODS: We conducted a retrospective study of newly diagnosed cases with EoE at the University of North Carolina from 2002 to 2018. Psychiatric comorbidities and relevant treatments were extracted from the medical records. The demographic and clinical features of patients with EoE with and without psychiatric diagnoses, and those with and without psychiatric medication use, were compared. RESULTS: Of 883 patients (mean age 26.6 years, 68% men, 79% white), 241 (28%) had a psychiatric comorbidity. The most common diagnosis was anxiety (23%) followed by depression (17%); 28% of patients were treated pharmacologically. There were 45 patients (5%) treated pharmacologically without a psychiatric diagnosis for chronic pain syndromes, insomnia, and/or epilepsy. Cases with EoE with a psychiatric diagnosis were more likely to be women, white, and 18 years or older and to have a longer symptom duration before diagnosis. DICUSSION: Psychiatric comorbidities were common in EoE, seen in a third of adults and more than 1 in 7 children, and with similar proportions receiving a prescription medication. These illnesses affected the EoE presentation because psychiatric comorbidities were more likely in older, female, and white patients with a longer duration of symptoms preceding diagnosis.

Relationship Between Housing Components and Development of Eosinophilic Esophagitis.

BACKGROUND: While the environment contributes to EoE pathogenesis, few environmental risk factors for EoE have been identified. AIM: To determine whether housing components such as exterior materials, heating systems, and house age are associated with EoE. METHODS: This case-control study used the UNC EoE clinicopathologic database to identify newly diagnosed EoE patients. Controls were patients without EoE who underwent endoscopy during the study time frame. Housing data were collected from publicly available online sources, and cases and controls were compared. The primary analysis was restricted to those living at their provided address at the time of diagnostic endoscopy. Multivariable logistical regression estimated associations after adjusting for potential confounders. RESULTS: Of 451 EoE cases and 2421 controls identified, the primary analysis included 158 cases and 769 controls. Compared to controls, EoE cases were more likely to have a house with a brick exterior (35% vs 26%; p = 0.04), gas heating (14% vs 8%; p = 0.06), or forced air (57% vs 45%; p = 0.009). In adjusted analysis, brick exterior was positively associated with EoE diagnosis [aOR 1.83 (95% CI 1.11-3.02)]. The average duration a patient lived in their house before EoE diagnosis was 7.2 ± 5.9 years, while symptom duration prior to diagnosis was 6.8 ± 8.4 years. CONCLUSION: EoE patients were more likely to have houses with a brick exterior, forced air, or gas heating, and brick exteriors were independently associated with EoE. Since symptoms generally started after moving into a house, housing-related environmental exposures may contribute to EoE disease development.

Long-term Continued Proton Pump Inhibitor Use is Common in Patients Diagnosed with Eosinophilic Esophagitis Despite Failure of Histologic Response: Data from a two-centre study: Long-term PPI Use in Patients with EoE.

Background and Aims: Treatment paradigms for proton pump inhibitors (PPIs) in eosinophilic esophagitis (EoE) are evolving. We aimed to determine patterns of long-term PPI use after EoE diagnosis in PPI histologic non-responders. Methods: We conducted a retrospective review at University of Colorado (UCH) and University of North Carolina (UNC) of EoE patients who were histologic non-responders to PPIs. Data were extracted from electronic medical records related to demographics, PPI use, and reasons for continuing or stopping PPI. Results: Of 67 patients in the UCH cohort, PPIs were initially discontinued in 9 (13%). Of 58 remaining on PPI, 48% were not instructed to discontinue therapy and 26% continued for symptom improvement. Of 675 patients at UNC, PPI was stopped in 185 (27%). Of patients remaining on PPI, 15% were not told to discontinue therapy and 62% were continued for symptom improvement. At last contact, >50% of patients remained on PPI at both centres with most common reasons for continuation being symptom improvement and not telling patients to discontinue. In the UNC cohort, clinical features associated with remaining on PPI included children younger than 18 years (p=0.01), males (p<0.001), heartburn symptoms (p<0.001) and hiatal hernia (p=0.004). Patients with dysphagia were less likely to remain on PPIs (p<0.001). Conclusions: Long-term PPI use is common in EoE patients even without histologic response. Failure to instruct patients to discontinue therapy was a common reason for long-term use, thus PPI use should be revisited in all EoE patients to confirm clinical benefit.

Distal esophagus is the most commonly involved site for strictures in patients with eosinophilic esophagitis.

While strictures are common in eosinophilic esophagitis (EoE), there are few data on stricture distribution and characteristics. Our primary aim was to characterize strictures by location in the esophagus in EoE and associated clinical, endoscopic, and histologic features. This was a retrospective study from the UNC EoE Clinicopathologic Database of subjects with esophageal strictures or narrowing from 2002 to 2017. Strictures were categorized as distal esophagus/gastroesophageal junction, mid-esophagus, proximal esophagus, or diffusely narrowed. Stricture location was assessed and compared with clinical, endoscopic, and histologic features, and also with treatment response to diet or topical steroids. Efficacy of combination therapy with dilation and intralesional steroid injection was assessed in a sub-group of patients with strictures. Of 776 EoE cases, 219 (28%) had strictures, 45% of which were distal, 30% were proximal, 5% were mid-esophageal, and 20% had diffuse narrowing. Those with mid-esophageal strictures were younger (P = 0.02) and had shorter symptom duration (P < 0.01). Those with diffuse esophageal narrowing were more likely to be women (57%) and have abdominal pain (25%). There was no association between other clinical, endoscopic, and histologic findings and treatment response based on stricture location. Fourteen patients (8%) received intralesional triamcinolone injection and subsequently achieved a higher mean dilation diameter after injection (13.7 vs. 15.5 mm; P < 0.01). In conclusion, almost half of strictures in EoE patients were in the distal esophagus. Therefore, EoE should be a diagnostic consideration in patients with focal distal strictures and not presumed to be secondary to gastroesophageal reflux disease.

Combination Therapy With Elimination Diet and Corticosteroids Is Effective for Adults With Eosinophilic Esophagitis.

Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated disorder defined by eosinophilic-predominant inflammation and esophageal dysfunction.1,2 EoE represents an important cause of esophageal morbidity and a leading cause of esophagitis.3.
