To the best of my knowledge, this is the first report comparing Giemsa and PAS-AB staining for the detection of H. pylori in such biopsies. \n\nMethods: The formalin-fixed paraffin-embedded blocks of 49 gastric biopsies from different patients were collected from the archive of anatomical pathology at King Abdulaziz Medical City, National Guard, Riyadh, Saudi Arabia. From each block, three slides were prepared and analysed using the hematoxylin and eosin (H&amp;E), Giemsa and PAS-AB stains to detect the presence\/absence of H. pylori, and the results were compared in terms of sensitivity, specificity and applicability. \n\nResults: The majority of the biopsies in this study showed antrum-type gastric mucosa. Only 15 biopsies showed active gastritis, whereas the rest showed chronic gastritis. Three biopsies showed intestinal metaplasia. All were detected by PAS-AB stain, but only two-thirds were detected by H&amp;E stain. Fifteen gastric biopsies showed H. pylori infection in general and in 13 of them, active gastritis cases were discovered. Fourteen out of these 15 H. pylori infection cases were detected by Giemsa stain, whereas only 13 cases were detected by H&amp;E stain. PAS-AB stain showed the worst results since it demonstrated only 40% sensitivity and 67.65% specificity in H. pylori detection. \n\nConclusion: Giemsa stain has better sensitivity and specificity in gastric H. pylori infection detection than PAS-AB. Therefore, using PAS-AB stain to detect H. pylori infection is not recommended.<\/jats:p>","DOI":"10.21315\/mjms2020.27.5.6","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T02:24:10Z","timestamp":1604024650000},"page":"53-61","source":"Crossref","is-referenced-by-count":15,"title":["Evaluation of Better Staining Method among Hematoxylin and Eosin, Giemsa and Periodic Acid Schiff-Alcian Blue for the Detection of Helicobacter pylori in Gastric Biopsies"],"prefix":"10.21315","volume":"27","author":[{"given":"Abdullah Saleh","family":"Alkhamiss","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Collage of Medicine, Qassim University, Qassim, Saudi Arabi"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8963","published-online":{"date-parts":[[2020,10,27]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Crowe SE.
