Background/Aims : The detection of Helicobacter pylori(H. pylori) both before and
after treatment is very important, but conventional methods to detect H. pylori are less
specific. The aim of this study was to evaluate the efficiency of polymerase chain
reaction (PCR) assay as a diagnostic method of H. pylori infection.
Methods : One hundred ninety three patients were included in the study, Their biopsy
specimens obtained from gastric antrum and body were submitted to PCR assay, rapid
urease test (CLO test), culture, and histological examination.
Results : Fifty eight percent (111 out of 193 patients) of the patients had H. pylori
infection. The diagnostic sensitivity/specificity of PCR assay, rapid urease test,
histological examination, and culture were 98.2%/95.1%, 95.5%/74.4%, 86.5%/98.8%, and
73.9%/l00%, respectively. The positive predictive value/negative predictive value of PCR
assay, rapid urease test, histological examination, and culture were 96.5%/97.5%,
83.5%/92.4%, 99%/84.4%, and 100%/73.9%, respectively The highest sensitivity was
achieved in the PCR assay, while the highest specificity was obtained in culture.
Conclusions : PCR assay was proved to be the most sensitive test with high
specificity for the detection of H. plyori.
