Expert Recommendations on the Diagnosis of Eosinophilic Esophagitis in the United Arab Emirates.

Eosinophilic esophagitis (EoE) is a chronic, progressive, type 2 inflammatory esophageal disease presenting as dysphagia to solid food and non-obstructive food impaction. Knowledge gaps exist in its diagnosis and management. These expert recommendations focused on the diagnosis of EoE in the United Arab Emirates. An electronic search of PubMed and Embase databases was used to gather evidence from systematic reviews, randomized controlled trials, consensus papers, and expert opinions from the last five years on the diagnosis of EoE. The evidence was graded using the Oxford system. Literature search findings were shared with the expert panel. A 5-point scale (strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree) was used, and a concordance rate of >75% among experts indicated agreement. Using a modified Delphi technique, 18 qualified experts provided 17 recommendations. Eleven statements achieved high agreement, four got moderate agreement, and two got low agreement. Challenges exist in diagnosing EoE, particularly in children. Esophageal biopsies were crucial in diagnosis, irrespective of visible mucosal changes. Further research on diagnostic tools like endoscopic mucosal impedance and biomarkers is needed. Diagnosis relies on esophageal biopsies and symptom-histology correlation; however, tools like EoE assessment questionnaires and endoscopic mucosal impedance could enhance the accuracy and efficiency of EoE diagnosis. The diagnosis of EoE is challenging since the symptoms seldom correlate with the histological findings. Currently, diagnosis is based on patient symptoms and endoscopic and histological findings. Further research into mucosal impedance tests and the role of biomarkers is needed to facilitate diagnosis.

Delayed brain abscess as a complication of cerebral infarction: A rare case report and review of the literature.

INTRODUCTION: Systemic infections are a common complication of cerebral stroke, while the development of a cerebral abscess on the background of infarcted brain tissue is an extremely rare occurrence. Here, we present a new case alongside a literature review. CASE PRESENTATION: A previously healthy 37-year-old man presented with sudden right-sided weakness and speech difficulties, progressing to complete aphasia. Initial tests showed no abnormalities, but subsequent CT scans revealed left basal ganglia infarction. Despite treatment and improvement, three months later, his condition worsened, leading to surgical intervention to excision of a cerebral abscess caused by Staphylococcus aureus. Following successful surgery and treatment, the patient showed improvement and was discharged for regular follow-up care. DISCUSSION: The convergence of stroke and brain abscess poses serious clinical challenges, requiring prompt diagnosis and treatment to mitigate catastrophic consequences. Brain abscess, stemming from cerebral infection, may arise from various sources, including contiguous spread, hematogenous dissemination, or traumatic injury. Diagnosis is complicated by nonspecific radiological findings, which often lead to misdiagnosis. Risk factors include age, immunocompromised states, and certain medical conditions. Despite challenges, early detection and appropriate management, involving surgical drainage and antimicrobial therapy, are crucial for favorable outcomes. CONCLUSION: Cerebral abscess following cerebral infarction is rare but should be suspected in patients with prior stroke or hemorrhage, experiencing worsening focal deficits and consciousness. Advanced age and comorbidities increase clinical suspicion.

Deciphering salivary microbiome signature in Crohn's disease patients with different factors contributing to dysbiosis.

Crohn's disease (CD) is a chronic inflammatory bowel disease. An imbalanced microbiome (dysbiosis) can predispose to many diseases including CD. The role of oral dysbiosis in CD is poorly understood. We aimed to explore microbiome signature and dysbiosis of the salivary microbiome in CD patients, and correlate microbiota changes to the level of inflammation. Saliva samples were collected from healthy controls (HC) and CD patients (n = 40 per group). Salivary microbiome was analyzed by sequencing the entire 16S rRNA gene. Inflammatory biomarkers (C-reactive protein and calprotectin) were measured and correlated with microbiome diversity. Five dominant species were significantly enriched in CD, namely Veillonella dispar, Megasphaera stantonii, Prevotella jejuni, Dolosigranulum pigrum and Lactobacillus backii. Oral health had a significant impact on the microbiome since various significant features were cariogenic as Streptococcus mutans or periopathogenic such as Fusobacterium periodonticum. Furthermore, disease activity, duration and frequency of relapses impacted the oral microbiota. Treatment with monoclonal antibodies led to the emergence of a unique species called Simonsiella muelleri. Combining immunomodulatory agents with monoclonal antibodies significantly increased multiple pathogenic species such as Salmonella enterica, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Loss of diversity in CD was shown by multiple diversity indices. There was a significant negative correlation between gut inflammatory biomarkers (particularly calprotectin) and α-diversity, suggesting more inflammation associated with diversity loss in CD. Salivary dysbiosis was evident in CD patients, with unique microbiota signatures and perturbed species that can serve as disease biomarkers or potential targets for microbiota modulation. The interplay of various factors collectively contributed to dysbiosis, although each factor probably had a unique effect on the microbiome. The emergence of pathogenic bacteria in the oral cavity of CD patients is alarming since they can disturb gut homeostasis and induce inflammation by swallowing, or hematogenous spread of microbiota, their metabolites, or generated inflammatory mediators.

Development of Novel Eating Error Scoring Tool to Evaluate Adult Eating Behavior Anomalies Among the United Arab Emirates Population.

Introduction Maladaptive eating behaviors are emerging as the most significant determinants of obesity with a promising role in intervention. In the absence of a standardized tool to assess eating variations, an Eating Error Score (EES) tool was devised which comprised five zones for evaluating the severity of obesogenic behaviors as well as the specific area(s) with the highest susceptibility. This pilot study was aimed at evaluating the effectiveness of the EES in quantitating the eating behavior errors associated with excess weight and identifying the most affected zones. Methods The EES questionnaire was designed to explore potential disturbances in five zones of eating behavior related to the impetus to eat (Munger), meal choices and attentiveness to cravings (Impulsive), consumption speed (Speed feeding), cues to stop ingestion (Indulgent) and the social aspect of eating (Relationship). The questionnaire was conducted on adults with varying body mass index (BMI) attending governmental outpatient clinics. The correlation between EES and BMI was determined through Pearson Coefficient. Results A total of 204 participants completed the EES questionnaire. There were 72 males and 132 females with a mean BMI of 27.63 ± 6.16 kg/m2 and with nearly equal distribution between normal weight (37.2%), overweight (32.4%), and obese (29.4%) individuals. Nearly 75% of our cohort had a moderate total EES, and the remainder was equally distributed between the mild and severe ranges. A weak but significant correlation was observed between total EES and BMI (r=0.275, p<0.001) suggesting increasing obesogenic styles in participants with excess weight. In addition, a similar weak but significant correlation was noted between Body Mass Index and the Munger and Impulsive zones (r=0.266 and 0.258 and p<0.001, respectively) suggesting more severe maladaptive eating behaviors in these areas. No correlation was found with the Speed feeding, Indulgent, and Relationship zones. Conclusion The EES may be a useful tool for assessing the extent of maladaptive eating behaviors, which predispose individuals to weight gain and sabotage their weight loss efforts. Undoubtedly, the utility of the tool needs to be corroborated in large population studies. Further, identifying the specific operant zones may show promise as many of these habits are potentially modifiable and can be targeted for weight control, most notably those associated with the Munger and Impulsive zones.

Cerebral venous sinus thrombosis in COVID 19 patients: Report of 2 cases.

Background: Initially, novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) was considered primarily a respiratory pathogen. However, with time it has behaved as a virus with the potential to cause multi-system involvement, including neurological manifestations which varies from acute to subacute onset of headache, seizures, a decrease of consciousness, and paralysis. Case description: Two cases of cerebral sinus venous thrombosis in COVID-19 patients were reported, following respiratory disorders, which was triggered by the SARS-CoV-2 infection. The first patient, presented with a decrease in level of consciousness and hemiparesis, was 23 years old female having no history of previous medical co-morbidities. The latter case, 21 years old woman showed less severe presentations of COVID-19 associated with headache, vomiting and papilledema. These two cases marvellously improved with no neurological deficit with aggressive course of anticoagulation. Conclusion: CVST should be suspected in COVID-19 patients presenting with headache, paralysis, aphasia or seizures. The high mortality rate of CVST in COVID-19 infection warrants a high index of suspicion from physicians, and early treatment with anticoagulation should be initiated.

Adolescent eating behaviors in the UAE: Time to intervene.

BACKGROUND: Obesity is the single most burdensome lifestyle disease, which has reached epidemic proportions. This study aimed to examine the eating behavior patterns and beliefs in a group of adolescents living in the United Arab Emirates (UAE). PROCEDURE: A questionnaire was administered to adolescents (aged 11 and 18 years) attending outpatients' clinics at governmental health facilities. Informed consent was obtained, and the questionnaire was available in English or Arabic languages. RESULTS: In all, 36 adolescent subjects participated in our study with 12 males and 24 females. UAE nationals constituted 72% of our participants and 28% were of other ethnic backgrounds; 75% were overweight to obese with 17% normal and 8% underweight. The majority of patients were healthy with only 6 patients suffering chronic medical diseases. We uncovered that in less than half of our cohort, the decision to eat came directly from the individuals themselves, but it was more influenced by their families. Food consumption was largely in response to physical hunger with the sensation perceived in the upper abdomen by one-third and the remainder localizing it to various other areas. Excessive caloric intake with frequent meals and snacks was also reported. Our study subjects decided what to consume mainly based on what appeared appetizing, followed by availability and cravings and to a lesser extent based on health recommendations. Excessive speed of food ingestion was self-reported in the majority of participants. Moreover, almost half of the adolescents were unable to turn down food offerings from their close family members and over one-fourth were unable to refuse food from other persons. Common symptoms reported included dysphoric mood, disordered sleep, decreased energy and concentration difficulties as well as low self-esteem. CONCLUSION: Our study uncovered certain eating behaviors in the cohort of adolescents, which may be important in promoting weight gain. These included misconceived hunger signals, excessive frequency, amount and speed of food consumption as well as more focus on food taste, inattentiveness to cravings and a strong social influence on food intake decisions. The findings of our study aim to shed some light on the eating patterns among adolescents and encourage research to investigate eating behaviors on an expanded scale evaluating ethnic, gender and age-related differences.

Burden and impact of arrhythmias in asthma-related hospitalizations: Insight from the national inpatient sample.

BACKGROUND: This study aimed to analyze the burden and impact of cardiac arrhythmias in adult patients hospitalized with asthma exacerbation using the nationwide inpatient database. METHODS: We used the National Inpatient Sample (NIS) database (2010-2014) to identify arrhythmias in asthma-related hospitalization and its impact on inpatient mortality, hospital length of stay (LOS), and hospitalization charges. We also used multivariable analysis to identify predictors of in-hospital arrhythmia and mortality. RESULTS: We identified 12,988,129 patients hospitalized with primary diagnosis of asthma; among them, 2,014,459(16%) patients had cardiac arrhythmia. The most frequent arrhythmia identified is atrial fibrillation (AFib) (8.95%). The AFib and non-AFib arrhythmia group had higher mortality (3.40% & 2.22% vs 0.74%), mean length of stay (LOS) (5.9 & 5.4 vs 4.2 days), and hospital charges ($53,172 & $51,105 vs $34,585) as compared to the non-arrhythmia group (P < .005). Predictors of arrhythmia in asthma-related hospitalization were history of PCI or CABG, valvular heart disease, congestive heart failure (CHF), and acute respiratory failure. Predictors of higher mortality in arrhythmia group were acute respiratory failure, sepsis, and acute myocardial infarction. CONCLUSIONS: Around 16% of adult patients hospitalized with asthma exacerbation experience arrythmia (mostly AFib 8.95%). The presence of arrhythmias was associated with higher in-hospital mortality, LOS, and hospital charges in hospitalized asthmatics.

Forty-One-Year-Old Man with Pulmonary Embolism 5 Months After COVID-19.

BACKGROUND: Hypercoagulation is one of the striking features of COVID-19. Patients hospitalized with COVID-19 are at high risk for venous thromboembolism. However, it is unknown if the risk for venous thromboembolism persists after discharge. CASE SUMMARY: We report a case with pulmonary embolism 5 months after COVID-19. No risk factors for venous thrombosis have been identified. CONCLUSION: In COVID-19 related hospitalization, large studies are needed to identify the risk of venous thromboembolism after discharge.

Optimizing biologic therapy in inflammatory bowel disease: a Delphi consensus in the United Arab Emirates.

BACKGROUND: Inflammatory bowel diseases (IBD) are chronic, relapsing-remitting inflammatory conditions with a substantial negative impact on health-related quality of life and work productivity. Treatment of IBD has been revolutionized by the advent of biologic therapies, initially with anti-TNF agents and more recently with multiple alternatives targets, and yet more under development. OBJECTIVES: Approximatively one third of patients do not respond to biologic therapy and more importantly a significant proportion experiences partial response or loss of response during treatment. The latter are common clinical situations and paradoxically are not addressed in the commercial drug labels and available guidelines. There is therefore a clinical need for physicians to understand when and how eventually to optimize the biologic therapy. DESIGN: This consensus using a Delphi methodology was promoted and supported by the Emirates Society of Gastroenterology and Hepatology to close this gap. DATA SOURCES AND METHODS: Following an extensive systematic review of over 60,000 studies, 81 studies with dose escalation and five addressing drug monitoring were selected and in addition five systematic reviews and three guidelines. RESULTS AND CONCLUSION: after three rounds of voting 18 statements were selected with agreement ranging from of 80% to 100.

First United Arab Emirates consensus on diagnosis and management of inflammatory bowel diseases: A 2020 Delphi consensus.

Ulcerative colitis and Crohn's disease are the main entities of inflammatory bowel disease characterized by chronic remittent inflammation of the gastrointestinal tract. The incidence and prevalence are on the rise worldwide, and the heterogeneity between patients and within individuals over time is striking. The progressive advance in our understanding of the etiopathogenesis coupled with an unprecedented increase in therapeutic options have changed the management towards evidence-based interventions by clinicians with patients. This guideline was stimulated and supported by the Emirates Gastroenterology and Hepatology Society following a systematic review and a Delphi consensus process that provided evidence- and expert opinion-based recommendations. Comprehensive up-to-date guidance is provided regarding diagnosis, evaluation of disease severity, appropriate and timely use of different investigations, choice of appropriate therapy for induction and remission phase according to disease severity, and management of main complications.

Coronavirus Disease 2019 in Immunocompromised Organ Transplant Recipients: A Case Report and Review of the Literature.

Coronavirus disease 2019 (COVID-19) is an ongoing pandemic caused by a novel coronavirus called severe acute respiratory syndrome coronavirus 2. Our understanding of this new disease continues to grow. The impact of the disease on immunocompromised transplant recipients is largely unknown. We present a case of a solid organ transplant recipient on immunosuppressive therapy who successfully recovered from COVID-19 infection. We also review 10 similar cases found in the literature and describe the clinical course and management, including immunosuppressive therapy.

Consensus Statement by an Expert Panel on the Diagnosis and Management of Iron Deficiency Anemia in the Gulf Cooperation Council Countries.

BACKGROUND: Iron deficiency (ID) and ID anemia (IDA) are common in the member states of the Gulf Cooperation Council (GCC). The unique genetic and lifestyle factors of the patient population in the region have necessitated the development of recommendations to help educate health-care professionals on appropriate diagnosis and management of ID/IDA. METHODS: A panel of regional experts, including gastroenterologists and hematologists with expertise in the treatment of IDA, was convened to develop regional practice recommendations for ID/IDA. After reviewing the regional and international literature, the expert panel developed consensus recommendations for screening, diagnosis, and treatment of patients with IDA in the GCC region. RESULTS: The recommendations proposed were customized to the patient population keeping in view the increasingly recognized burden of coeliac disease, high fertility and obesity rates, high prevalence of alpha- and beta-thalassemia traits, and poor tolerance and low treatment compliance with oral iron therapy. CONCLUSIONS: This consensus statement proposes recommendations for screening, diagnosis, and treatment of IDA in the GCC region.

The molecular mechanisms of action of the endocrine disrupting chemical bisphenol A in the development of cancer.

The endocrine disrupting chemical (EDC) is an exogenous substance or mixture that alters the function of the endocrine system and consequently causes adverse effects in intact organisms. Bisphenol A (BPA), one of the most common endocrine disrupting chemicals is a carbon-based synthetic compound used in the production of water bottles, cans, and teeth suture materials. It is known to be a xenoestrogen as it interacts with estrogen receptors and acts as agonist or antagonist via estrogen receptor-dependent signaling pathways. BPA has been associated with serious health effects in humans and wildlife. It elicits several endocrine disorders and plays a role in the pathogenesis of several hormone-dependent tumors such as breast, ovarian, prostate cancer and others. More complicate to this picture, its effects rely on several and diverse molecular and epigenetic mechanisms that converge upon endocrine and reproductive systems. The present review gives an overview of general hazards of BPA, its epigenetic modifications and the molecular mechanisms of BPA action in different types of cancers as the increase in information about responses and action mechanisms of BPA may bring a better understanding of the risks of BPA exposure in humans and provide an important platform on which human health can be improved.

Profiling cellular bioenergetics, glutathione levels, and caspase activities in stomach biopsies of patients with upper gastrointestinal symptoms.

AIM: To measure biochemical parameters in stomach biopsies and test their suitability as diagnostic biomarkers for gastritis and precancerous lesions. METHODS: Biopsies were obtained from the stomachs of two groups of patients (n = 40) undergoing fiber-optic endoscopy due to upper gastrointestinal symptoms. In the first group (n = 17), only the corpus region was examined. Biopsies were processed for microscopic examination and measurement of mitochondrial O2 consumption (cellular respiration), cellular adenosine triphosphate (ATP), glutathione (GSH), and caspase activity. In the second group of patients (n = 23), both corpus and antral regions were studied. Some biopsies were processed for microscopic examination, while the others were used for measurements of cellular respiration and GSH level. RESULTS: Microscopic examinations of gastric corpus biopsies from 17 patients revealed normal mucosae in 8 patients, superficial gastritis in 7 patients, and chronic atrophic gastritis in 1 patient. In patients with normal histology, the rate (mean ± SD) of cellular respiration was 0.17 ± 0.02 µmol/L O2 min(-1) mg(-1), ATP content was 487 ± 493 pmol/mg, and GSH was 469 ± 98 pmol/mg. Caspase activity was detected in 3 out of 8 specimens. The values of ATP and caspase activity were highly variable. The presence of superficial gastritis had insignificant effects on the measured biomarkers. In the patient with atrophic gastritis, cellular respiration was high and ATP was relatively low, suggesting uncoupling oxidative phosphorylation. In the second cohort of patients, the examined biopsies showed either normal or superficial gastritis. The rate of cellular respiration (O2. µmol/L min(-1) mg(-1)) was slightly higher in the corpus than the antrum (0.18 ± 0.05 vs 0.15 ± 0.04, P = 0.019). The value of GSH was about the same in both tissues (310 ± 135 vs 322 ± 155, P = 0.692). CONCLUSION: The corpus mucosa was metabolically more active than the antrum tissue. The data in this study will help in understanding the pathophysiology of gastric mucosa.

Splenic abcess owing to brucellosis.

Brucellosis, caused by aerobic Gram-negative coccabacilli, is prevalent worldwide. It occurs mainly because of the consumption of unpasteurised milk and contact with animals. The disease is particularly hyperendemic in the Mediterranean region and Arabian Peninsula. Its high prevalence in the UAE continues to be a major health problem, causing significant morbidity and mortality. According to the Ministry of Health, 119 cases were reported in 2010, and most of those cases were patients aged over 45. Even though an effective treatment is available for this disease, treatment failure frequently occurs owing to delay in diagnosis, relapses and its prolonged clinical course. We present a 33-year-old man who was admitted to our internal medicine teaching unit service with non-specific symptoms. A workup revealed Brucella in the blood cultures. An abdominal ultrasound showed multiple splenic abscesses. After treatment with triple therapy, the patient has remained asymptomatic at 2 years follow-up.

Delayed life-threatening upper gastrointestinal bleeding as a complication of laparoscopic adjustable gastric banding: case report and review of the literature.

Morbid obesity is a common health problem worldwide. Laparoscopic adjustable gastric banding has been used extensively around the world for the treatment of morbid obesity. Life-threatening hemorrhage as a late complication of laparoscopic adjustable gastric banding is extremely rare. We report a case of massive upper gastrointestinal bleeding due to intragastric erosion of a gastric band 6 years postoperatively and review the English literature on this life-threatening rare condition. Initially, the patient was aggressively resuscitated and treated conservatively. After 1 year, the band was removed laparoscopically following an unsuccessful attempted removal by endoscopy. Clinicians who follow up patients with gastric banding should be aware of this condition. The early detection of erosion is important to avoid this serious complication.

Could imatinib replace surgery in esophageal gastrointestinal stromal tumor.

Gastrointestinal stromal tumors GISTs are cellular spindle, or epithelioid tumors that occur in the stomach, intestine, and rarely in the esophagus. A 61-year-old man was complaining of resistant dry cough with dysphagia for one month duration. Upper gastrointestinal tract endoscopic examination showed a polypoid mass 30 cm from the incisors obstructing 50% of the lumen, where multiple biopsies were taken. Magnetic resonance imaging MRI showed a mass in the wall of the esophagus extending into the thoracic cavity. Histologically, the stained sections with the routine hematoxylin and eosin as well as the immunohistochemical stains for CD117, CD34, S100, vimentin, and smooth muscle actin confirmed the diagnosis of esophageal GIST. The patient was treated with imatinib, 400 mg/day. There was a dramatic reduction in the size of the tumor with successful improvement of his symptoms after 2 months of treatment, which was confirmed by repeated upper GIT endoscopy, and MRI.
