Abstract
Prevalence of gastroesophageal reflux disease (GERD) varies in regions, but few reports on clinical features and quality of life (QOL) of asymptomatic GERD exist in Japan. Endoscopy was performed in our department between April 2008 and September 2010. Among 6409 cases answering Frequency of Scale for the Symptoms of GERD (FSSG) and SF8 QOL (PCS: physical component summary; MCS: mental component summary), proton pump inhibitor or histamine 2 receptor antagonist users were excluded, and 388 cases diagnosed as reflux esophagitis (RE) (Los Angeles Classification grade A, B, C, D) were analyzed. Asymptomatic cases with FSSG total score = 0 were defined as asymptomatic RE (AsymRE) and FSSG total score ≥ 1 as symptomatic RE (SymRE). Each clinical feature was analyzed. The frequency of AsymRE was 11.6% of RE (AsymRE, n = 45; SymRE, n = 343). Patient characteristics in AsymRE, SymRE were male/female = 35/10; 239/104 (not significant), mean age (year) = 63.5 ± 14.3; 58.3 ± 12.7 (P < 0.01), body mass index = 23.9 ± 4.3; 23.5 ± 3.7 (ns), respectively. Regarding the grade of RE, grade A 80.0%, B 17.8%, C 2.2% and D 0% in AsymRE, and grade A 72.6%, B 24.8%, C 2.0% and D 0.6% in SymRE (ns). PCS in SF8 was AsymRE; SymRE = 51.8 ± 9.8; 49.0 ± 7.7 (P < 0.01) and MCS in SF8 was AsymRE; SymRE = 51.4 ± 9.4; 48.2 ± 7.6 (P < 0.01), respectively. The prevalence of asymptomatic RE was high, particularly in elderly subjects. Unlike symptomatic RE, QOL was not impaired at all with asymptomatic RE. No differences were seen between groups in clinical features such as endoscopic severity of RE, indicating that asymptomatic RE is a condition that should not be overlooked clinically.Keywords
