Personal profile




Dr Chin Yen Tay has great interest in clinical Helicobacter pylori research, its genomics and the next generation sequencing technology. For the past 5 years, Dr Tay has been profiling and monitoring the antibiotic resistant pattern of H. pylori in Western Australia. Through the antibiotic susceptibility testing, the clinicians were able to prescribe a personalized treatment and achieve a cure rate of over 95% among multi-drug resistant cases. Since H. pylori has strong association with gastric cancer, and China is a gastric cancer hotspot, many doctors in China are still under tremendous stress for not able to eradicate H. pylori infection due to antibiotic resistance. Moreover, only a handful of laboratories in China is capable of culturing H. pylori. Therefore, in 2017, via a successful grant application with Shenzhen Dapeng Hospital, Dr Tay was given a supportive grant from Shenzhen Dapeng Hospital to help develop capability in H. pylori research. Not only that the Shenzhen Dapeng Hospital has become one of the best hospitals in culturing H. pylori, their success rate in treating antibiotic resistant H. pylori patients has also dramatically improved. Dr Tay has showed that the culturing technique is transferable and in 2018, funded by the Australian-China Councils Fellowship, has allowed him to provide a one-month training program in University of Western Australia, Helicobacter Research Laboratory. Dr Tay is hoping to use this opportunity to collaborate with more hospitals and research institutes in China to gain more understanding of the China H. pylori strain.
