Biography


Dr. Desmond Yat-Hin Yap joined the University Department of Medicine in 2004. His major research theme is immune-mediated glomerular diseases, with emphasis on lupus nephritis which is an important cause of renal failure especially in Asia. Importantly, his team is the first to report long-term outcomes of treatment with mycophenolate (the most commonly used standard-of-care, pioneered by his group) in lupus nephritis patients, and his work has elucidated the risk factors leading to disease relapse and also explored novel biomarkers for disease activity monitoring. Dr. Yap was the co-First author for Asian Guidelines for the management of lupus nephritis, published in the official journals of regional nephrology and rheumatology societies [Nephrology (Carlton) 2014; 19: 11-20 & Int J Rheum Dis 2013; 16: 25-36], and the first author of an invited review on the treatment of lupus nephritis in Asia (Kidney Dis 2015; 1: 100-9). He received the Hong Kong Society of Nephrology Young Investigator Award in 2009 for his research on serum immunoglobulin binding activity to human mesangial cells in lupus nephritis. Funded by the Li Shu Pui Clinical Fellowship (2014-2015), Dr. Yap worked as a research fellow at the Fiebiger-Nikolaus Centre, Friedrich-Alexander University, Germany to study B cell homeostasis in immune-mediated diseases.

Dr. Yap’s other research interest pertains to infective complications in renal failure patients, focusing on viral hepatitis in kidney transplant recipients and peritoneal dialysis-related peritonitis. He is a co-author for the chapter on infection control in a nephrology clinical practice guidelines to be jointly published by the Hospital Authority Central Renal Committee and the Hong Kong College of Physicians.

Research Profile

  1. Immunopathogenesis and use of immunosuppressive treatments in lupus nephritis
  2. Pathogenesis, monitoring and prevention of flares in lupus nephritis
  3. Viral hepatitis infection in renal failure patients
  4. Infective complications in peritoneal dialysis
