Kaiser Permanente Researcher Profiles

Joan C. Lo, MD, is a senior physician and research scientist at the Kaiser Permanente Northern California Division of Research; Associate Clinical Professor of Medicine at the University of California, San Francisco (UCSF); and endocrinologist at Kaiser Permanente Oakland Medical Center and San Francisco General Hospital. She is also directs clinical research center activities at the Division of Research in collaboration with UCSF’s Clinical and Translational Science Institute (CTSI). Dr. Lo’s current research interests center on endocrinologic conditions related to women’s health and chronic disease, including reproductive, pregnancy and post-menopausal disorders in women. Her work has also focused on endocrinologic and metabolic perturbations associated with HIV infection and chronic kidney disease.

Femur Fracture Outcomes Associated with Bisphosphonate Use

In clinical practice, oral bisphosphonate drugs are considered one of the main therapies for osteoporosis, based on strong clinical evidence of significant reduction in risk of hip, vertebral and non-vertebral fractures during the first 3-5 years of therapy. However, data are extremely limited regarding fracture outcomes beyond this initial treatment period and there have been concerns regarding long term adverse outcomes. This joint Kaiser California study proposes to fill an important knowledge gap by examining major osteoporotic fracture and atypical fracture outcomes among postmenopausal women with at least 3 years of bisphosphonate therapy. The aims are to: 1) Examine the association between long-term bisphosphonate use patterns and subsequent risk of osteoporotic fracture; and 2) estimate the association between long-term bisphosphonate use patterns and subsequent risk of atypical fracture.
