Abstract:

Globally, Helicobacter pylori (H. pylori) is becoming an increasingly troublesome economic and public health problem. Over 50% of the world’s population was estimated to harbor H. pylori in the upper gastrointestinal tract (GIT) and over 80% of them reside in developing nations. Unless treated, colonization persists lifelong where H. pylori presents a key factor in the etiology of GIT diseases; ranging from asymptomatic chronic gastritis up to gastric carcinoma. Therefore, accurate and timely diagnosis is the first step to address this burdensome problem. The aim of this descriptive-cross sectional study was to compare two non-invasive techniques for the diagnosis of H. pylori infection among university students. Stool and serum samples were collected from one hundred asymptomatic students to detect H. pylori antigens (Ags) in stool using chromatographic immunoassay and IgG antibodies (Abs) in serum by enzyme linked immune sorbent assay (ELISA). Fifty five (55%) of tested students were positive for each of stool Ags and serum Abs. The recorded sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the serum Ab test in relation to stool Ag test were 98.18%, 97.78%, 98.18 % and 97.78, respectively. There was very good agreement (98%) between the results of the two tests.
