Research & Publications

Research Summary

Dr. Wu’s current research is focused on women with cystic fibrosis (CF) and how estrogen supplementation may impact their health.

Her results show that women with CF who were taking supplemental estrogen such as combined oral contraceptives have higher quality of life scores than women with CF not taking supplemental estrogen. In a single-center cross-sectional study, women with CF taking estrogen supplementation (ethinyl estradiol) had lower bone mineral density than women with CF not taking ethinyl estradiol. Dr. Wu questions whether oral ethinyl estradiol, which is the common estrogen used in oral contraceptive pills, is adequate to protect bone health and if there needs to be a higher dose of estrogen or a different route like a patch to make a difference.

Dr. Wu is also doing research that looks at the impact of COVID-19 pandemic on the quality of life of patients with osteogenesis imperfecta and their access to care. Many individuals had delays in accessing medical providers and services relating to their care. The preliminary findings were presented at the virtual International Conference on Children’s Bone Health forum.
