dc.description.abstractThere are various methods for detection of Helicobacter pylori and the gold standard for non-invasive detection is the urea breath test (UBT). The aim of the study is therefore to detect H. pylori from the stool of patients with dyspepsia by PCR and compare results obtained with UBT. A total of 97 stool samples from patients presenting with dyspeptic symptoms in Lagos University Teaching Hospital (LUTH) were screened for urea breath test (UBT) and the presence of H. pylori DNA using stool-PCR. Out of 97 stool samples analysed, 38 (39.2%) were positive for Helicobacter spp. and 20 (20.6%) positive for H. pylori by PCR, through amplification of 16S rRNA and glmMgenes respectively. Of the 20 positive by glmM gene, the cagAgene was detected in 8 (40%) samples, while 47 (48.5%) out of 97 stool samples were positive for H. pylori by UBT. The sensitivity and specificity of the glmM gene compared with UBT as the gold standard is 42.6% and 100% respectively. The positive predictive value (PPV) was 100% while the negative predictive value (NPV) was 60%.The method may be useful for detecting H. pylori from stool amongst children especially where most hospitals lack endoscope for children although the method is expensive.en_US
