A 17-year-old female patient was diagnosed with Philadelphia positive B cell ALL in August 2018. She received dasatinib, vincristine, rituximab and dexamethasone induction and achieved deep molecular remission followed by haploidentical-HCT from her brother donor using fludarabine/TBI MAC conditioning in April 2019. Her course was complicated by falling chimerism and eventually autologous recovery with donor chimerism reaching zero on day 90 post-HCT. Her immunosuppression was stopped, and she was started on maintenance dasatinib. In July 2020, she tested positive for SARS-Cov2 by PCR after contact with a positive case. She is currently asymptomatic and continuing on dasatinib and acyclovir. Repeat nasal SARS-Cov2 PCR on August 20, 2020, was negative, but the SARS-Cov2 total antibody test was not done.
