Introduction: Helicobacter pylori (H. pylori) infection is one serious disease that could result in complications such as gastritis, peptic ulcer and gastric cancer. Both invasive and non-invasive methods have been used to detect the infection, however the best detection depends on the clinical setting. One way to determine this is by graphical radar plot analysis, as it provides practical and useful data for many clinical aspects. The aim of this study was to investigate the prevalence rate of H. pylori ureA genotypes infection with a graphical technique.
Method: We conducted a cross-sectional study in which data was collected from patients with infection symptoms in north peninsular Malaysia. All eligible subjects were required to perform a simple clinical procedure to provide their cell and saliva samples. Subjects were also examined by the medical staff based on their symptoms. Detection of H.pylori in the samples were conducted with three different detection methods such as culture, biopsy, saliva and the combination of thee three methods.
Results: Biopsies were cultured and revealed 19.2% (48/250) of the patients had H. pylori infection. However, when PCR and culture were combined, the prevalence of H. pylori infection jumped by three times to 59.6% (149/250), indicating that PCR on biopsies and saliva was more sensitive. Males who were not Malay and Malay males in the age range of 41 to 60 were found to have significantly different rates of H. pylori infection (p 0.05), according to age group. According to ethnicity, 49.5% (28/58) Malay men were infected compared to 68.1% (62/91) non-Malaysia men (p0.05), while there was no difference between 64.2% (34/53) non-Malaysia women and 51.1% (23/45) Malay women.
Conclusion: This study found that saliva method is accurate for the identification of H. pylori. This approach has several advantages that could be helpful to patients worldwide, thus diagnosis and treatment can be done earlier to prevent complications.
