Item Prevalence of eosinophilic oesophagitis among adult Sri Lankan patients with refractory upper gastrointestinal symptoms - a prospective study(Sri Lanka Medical Association, 2012) Ranawaka, C.K.; de Silva, A.P.; Hewavisenthi, S.J.; Jayathilake, T.M.A.H.; de Alwis, W.R.S.INTRODUCTION: Eosinophilic oesophagitis (EoE) is increasing in the West (community prevalence 0.02-1%), and is especially prevalent among patients with refractory upper gastrointestinal (UGI) symptoms (about 6.5-40%). Diagnosis is important as the treatment is with corticosteroids and other immunomodulators rather than acid suppression and prokinetics. EOE has been poorly studied in Asian populations. AIMS: To study the prevalence of EoE among adult Sri Lankan patients with refractory UGI symptoms. Methods: The study was carried out in the University Medical Unit of the Colombo North Teaching Hospital, Ragama. Over a period of one year from March 2011, consecutive, consenting patients (aged 18-70) referred for gastroduodenoscopy (OGD), with persistent UGI symptoms despite standard therapy for at least two months, were included. All patients underwent OGD with two biopsies each from the distal and mid oesophagus. A diagnosis of EoE was made when there were 15 or more intra-epithelial eosinophils per high-power field, according to international guidelines. RESULTS: 106 patients (M: F= 42:64 mean age 48 yrs (SD 13.3) were recruited. Common symptoms were refractory dyspepsia, gastro-oesophageal reflux and dysphagia in74, 64, 27 patients respectively. Endoscopy was macroscopically normal in 97 patients, and suggestive of EoE in 7; concentric mucosal rings in 3 and white exudates in 4 patients. Only 2 (1.9%) patients had histological evidence of EoE, one of whom had compatible macroscopic endoscopic features. CONCLUSIONS: The prevalence of EoE in this Sri Lankan cohort of adult patients with refractory UGI symptoms was much lower than reported in western series.
