OBJECTIVES: The most important treatment strategy for obstructive nephropathy is to protect renal tissue from the deleterious effects of fibrosis. Therefore, we sought to investigate the renoprotective effects of darbepoetin alfa on unilateral ureteral obstructions. METHODS: We used 12 female and 12 male 3-monthold Wistar rats weighing between 250 and 350 g. The rats were divided equally into sham, darbepoetin and control groups. With the exception of the sham group, left unilateral obstructions were applied to all of the rats...

Non-dysplastic Barrett's oesophagus (NDBE) occurs as a consequence of an inflammatory response triggered through prolonged gastro-oesophageal reflux and it may precede the development of oesophageal adenocarcinoma. NF-κB activation as a result of the inflammatory response has been shown in NDBE, but the possible mechanism involved in the process is unknown. The aim of this study was to assess, using immunohistochemistry, Survivin and Bcl3 expression as potential biomarkers for NF-κB activation along the oesophageal metaplasia-dysplasia-adenocarcinoma sequence...

Gastroesophageal reflux disease (GERD) and Barrett's Esophagus (BE), which are prevalent in the World Trade Center (WTC) exposed and general populations, negatively impact quality of life and cost of healthcare. GERD, a risk factor of BE, is linked to obstructive airways disease (OAD). We aim to identify serum biomarkers of GERD/BE, and assess the respiratory and clinical phenotype of a longitudinal cohort of never-smoking, male, WTC-exposed rescue workers presenting with pulmonary symptoms. Biomarkers collected soon after WTC-exposure were evaluated in optimized predictive models of GERD/BE...

This review focuses on the role of the lung microbiome in idiopathic pulmonary fibrosis. Although historically considered sterile, bacterial communities have now been well documented in lungs both in healthy and pathological conditions. Studies in idiopathic pulmonary fibrosis (IPF) suggest that increased bacterial burden and/or abundance of potentially pathogenic bacteria may drive disease progression, acute exacerbations, and mortality. More recent work has highlighted the interaction between the lung microbiome and the innate immune system in IPF, strengthening the argument for the role of both host and environment interaction in disease pathogenesis...

OBJECTIVE: Pepsin in saliva has been proposed as a biomarker for the diagnosis of laryngopharyngeal reflux (LPR), but the results remain controversial. We assessed the diagnostic value of pepsin in saliva for LPR. METHODS: PubMed, Embase, and Web of Science were searched for studies in English that evaluated the utility of pepsin in saliva in the diagnosis of LPR, published up to 15 March 2017. We used Stata 12.0 to summarize the diagnostic indexes for the meta-analysis...

BACKGROUND: Approximately, 20% of patients with heartburn and normal endoscopic findings do not symptomatically improve on proton pump inhibitor (PPI) therapy making diagnosis and treatment uncertain. A biomarker distinguishing PPI-responsive from PPI-refractory heartburn is desirable. AIMS: We performed a pilot study assessing whether carboxy(C)-terminal fragments (CTFs) of e-cadherin in esophageal biopsies or amino(N)-terminal fragments (NTFs) of e-cadherin in serum could serve this purpose...

BACKGROUND: None of current diagnostic methods has been proven to be a reliable tool for gastro-esophageal reflux disease (GERD). Pepsin in saliva has been proposed as a promising diagnostic biomarker for gastro-esophageal reflux. We aimed to determine the diagnostic value of salivary pepsin detection for GERD. METHODS: Two hundred and fifty patients with symptoms suggestive of GERD and 35 asymptomatic healthy volunteers provided saliva on morning waking, after lunch and dinner for pepsin determination using the Peptest lateral flow device...

Vesicoureteral reflux (VUR) is the most common type of obstructive uropathy in children. Reflux nephropathy (RN) is one of the most common complications of VUR that inevitably leads to chronic kidney disease. Patients with end-stage kidney disease require costly treatment, and the only way to cure them is kidney transplantation. A timely institution of renoprotective therapy is a key factor helping to preserve the function of the native kidneys. Hence, it is necessary to devise new highly sensitive and minimally invasive methods for early diagnosis of RN...

OBJECTIVE: Because both gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) are associated with malnutrition and feeding dysfunction, this study compares growth, nutrition and feeding behaviors in children with GERD and EoE. METHODS: Subjects aged 1-7 with GERD or EoE were enrolled in a prospective study. Assessments included length/height, weight, 3-day food diary, serum biomarkers of nutrition, and the Behavioral Pediatric Feeding Assessment Scale (BPFAS)...

Oesophageal adenocarcinoma is rapidly increasing in Western countries. This tumour frequently presents late in its course with metastatic disease and has a very poor prognosis. Barrett's oesophagus is an acquired condition whereby the native squamous mucosa of the lower oesophagus is replaced by columnar epithelium following prolonged gastro-oesophageal reflux and is the recognised precursor lesion for oesophageal adenocarcinoma. There are multiple national and society guidelines regarding screening, surveillance and management of Barrett's oesophagus, however all are limited regarding a clear evidence base for a well-demonstrated benefit and cost-effectiveness of surveillance, and robust risk stratification for patients to best use resources...

Laryngopharyngeal reflux (LPR) may contribute to the development of laryngeal diseases including vocal fold leukoplakia. Clinical methods of determining LPR are limited. Pepsin, as an exogenous protein, is considered as a biomarker of LPR. The aim of the current study was, therefore, to detect pepsin by immunohistochemistry in the biopsies from patients with vocal fold leukoplakia, and by which, to determine the potential association of LPR and vocal leukoplakia. A total of 26 biopsies from patients with vocal fold leukoplakia were examined in comparison with 20 vocal fold biopsies from control subjects...

Functional heartburn (FH) is defined as a functional esophageal disorder characterized by symptoms of chronic heartburn with no apparent correlation to acid or nonacid reflux. In addition, its symptoms persist despite the lack of organic abnormalities or inflammation, esophageal motility disorders, or metabolic disorders. Although conditions presenting with esophageal symptoms without endoscopic abnormalities were previously categorized as nonerosive reflux disease, such conditions are now classified into 3 categories under Rome IV criteria: nonerosive reflux disease, reflux hypersensitivity, and FH...

OBJECTIVE: To identify laryngeal mRNA gene changes in patients with laryngopharyngeal reflux (LPR). METHOD: Laryngeal biopsies from non-smoking LPR patients (n=10; Reflux Symptom Index (RSI) >12 and a Reflux Finding Score (RFS) >6) and controls (n=9; RSI <12 and RFS <6) were collected from four subsites (true vocal cord, false vocal cord, medial arytenoid and posterior commissure) of the larynx. qRT-PCR analyses were conducted on 20 reflux- and inflammation-related genes, including interleukins 6 and 8, cytokeratins 8 and 14, mucin genes MUC1, MUC2, MUC3B, MUC4, MUC5B, MUC6 and MUC7 and carbonic anhydrase III...

The work-up of a febrile urinary tract infection is generally performed to detect vesicoureteral reflux (VUR) and its possible complications. The imaging modalities most commonly used for this purpose are renal-bladder ultrasound, voiding cystourethrogram and dimercapto-succinic acid scan. These studies each contribute valuable information, but carry individual benefits and limitations that may impact their efficacy. Biochemical markers are not commonly used in pediatric urology to diagnose or differentiate high-risk disease, but this is the emerging frontier, which will hopefully change our approach to VUR in the future...

Barrett's esophagus (BE) predisposes patients to esophageal adenocarcinoma. 3 to 6% of individuals with gastro-esophageal reflux disease are estimated to have BE but only 20 to 25% of BE patients are currently diagnosed. The current gold standard for diagnosis of BE is per-oral upper GI endoscopy. As this is not suitable for large-scale screening, a number of alternative methods are currently being investigated: transnasal and video capsule endoscopy, endomicroscopy, cell collection devices like the cytosponge and biomarkers...
