Seroprevalence of among dyspeptic patients in northern Lebanon: a 6-year retrospective study in two tertiary hospitals Open Access

Abstract

causes chronic gastritis and plays a significant role in duodenal/gastric ulcer disease and gastric cancer. Its prevalence varies among different populations and geographical areas. Here, in a hospital-based retrospective study, we investigated the seroprevalence of infection in northern Lebanon. We examined the records of 4000 consecutive dyspeptic patients attending 2 tertiary care centres in the North (Tripoli) and Akkar (Halba) governorates. Seropositivity for was determined using enzyme immunoassays investigating specific anti- IgG antibodies. The association of infection with the available patients’ demographic characteristics was also evaluated. The mean age of our study population was 36.9±16.6 years. With 2486 female and 1514 male subjects, the overall female/male ratio was 1.64. In total, seropositivity was detected in 1367/4000 (34.2 %) tested individuals. The multivariate logistic regression analysis showed that infection is less prevalent in female than in male examined patients [adjusted odds ratio (OR): 0.84; 95 % confidence interval (CI): 0.73–0.96; <0.013]. Seroprevalence gradually increased with age – from 14.6 % in patients below 18 years to 42.9 % in those above 49 years – and was significantly higher among Akkar patients compared to those from the North governorate: 49.6 versus 28.7 %, respectively (<0.001). Overall, a third of symptomatic patients in northern Lebanon are infected with . However, the prevalence of infection was markedly different in close geographical zones in this region. Additional screening studies using different screening methods are needed in the future to determine the accurate prevalence of this bacterium and its clinical implications to establish efficient national intervention strategies.
