MM-239: A Tertiary Center Experience of Multiple Myeloma Patients with COVID-19: Lessons Learned and the Path Forward
2020
Context: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has resulted in over 100,000 deaths in the United States. Our institution has treated over 2,000 COVID-19 patients during the pandemic in New York City. Objective: We explored the population of myeloma patients who developed COVID-19 to identify risk factors tied to poor outcomes. Design: We performed a retrospective study of a cohort of 58 patients with a plasma cell disorder (54 MM, 4 smoldering MM) who developed COVID-19 between March 1, 2020 and April 30, 2020. We report epidemiological, clinical, and laboratory characteristics, including persistence of viral detection by polymerase chain reaction (PCR) and anti-SARS-CoV-2 antibody testing, treatments initiated, and outcomes. Setting: A large tertiary care cancer center in New York at the epicenter of the COVID-19 pandemic in the USA. Patients: Patient charts were analyzed retrospectively. Patients had MM or SMM and COVID-19. Results: Of the 58 patients diagnosed with COVID-19, 36 were hospitalized and 22 were managed at home. The median age was 67 years; 52% of patients were male, and 63% were non-white. Hypertension (64%), hyperlipidemia (62%), obesity (37%), diabetes mellitus (28%), chronic kidney disease (CKD, 24%), and lung disease (21%) were the most common comorbidities. In the total cohort, 14 patients (24%) died. Older age (>70 years), male sex, and cardiovascular risk were significantly (p Conclusions: Drug exposure and MM disease status at the time of contracting COVID-19 had no bearing on patient outcome. Mounting a severe inflammatory response to SARS-CoV-2 and severe hypogammaglobulinemia were associated with higher mortality. These findings pave a path to the identification of vulnerable patients who need early intervention to improve outcomes of myeloma patients in future outbreaks of COVID-19. The majority of myeloma patients mounted a specific antibody response to SARS-CoV-2.
