Clinical Medicine

This is the only clinical department in NEKKEN that engages in clinical practices in the Department of Infectious Diseases at Nagasaki University Hospital. We conduct a wide range of multi-disciplinary studies that bridge our strengths in clinical epidemiology with laborator y-based microbiology and immunology, both within and outside Japan. Our main research interests include respiratory infectious diseases, acute undifferentiated febrile illness, tuberculosis(TB), HIV/AIDS and others as described below:

Activities

Respiratory Infections Diseases, including Tuberculosis

We conduct TB research through international collaborations in the Philippines and West Africa, focusing on TB-specific cellular immune responses that predict disease progression. Additionally, we conduct clinical epidemiology research on respiratory infections such as influenza, RSV and COVID-19 in Japan and the Philippines.

Non-malarial Febrile Illness in the Tropical Countries

We are investigating acute undifferentiated febrile illness in the Department of Infectious Diseases, Bac Mai Hospital, Hanoi, Vietnam and the National Infectious Disease Hospital (San Lazaro Hospital) in the Philippines, applying various advanced diagnostic tests in collaboration with the National Institute of Infectious Disease in Tokyo and the London School of Hygiene and Tropical Medicine.

HIV/AIDS Studies and others

Our collaboration with National Institute of Health, Thailand on a natural history cohort of HIV infection is on-going. We investigate the molecular mechanisms of pathogenesis caused by the GILT enzyme and endogenous retroviruses. Additionally, a study on snake bite has started in the Philippines.
