Session: 653. Myeloma/Amyloidosis: Therapy, excluding Transplantation: Poster II
Hematology Disease Topics & Pathways:
Coronaviruses
Methods: The survey was proposed by the ISA Board and approved by the coordinating institution’s Ethics Committee. All members of the ISA were invited to participate by email and a link for participation is online on ISA website. RedCap software was used for the data collection.
Results: Twelve Institutions requested the access to the data collection system from 7 countries. At the data lock of July 26, 2020, 29 patients with systemic amyloidoses were collected from 7 different Institutions. Systemic AL amyloidosis patients reported so far were 19: 12 from the Pavia Amyloidosis Research and Treatment Center (Italy), 3 from the Boston Medical Center (USA), and 1 patient each from the Columbia University Hospital (New York, USA), Hospital Clinic (Barcelona, Spain), Clinica Universitaria de Navarra (Navarra, Spain) and Amyloidosis Centrum (Heidelberg, Germany). Eleven (58%) had heart involvement, 8 (42%) had kidney and two or more organs were involved in 9 patients (47%). The most frequent comorbidities reported were history of hypertension in 7 (37%) and cardiovascular diseases in 3 (16%). Four (21%) patients were newly diagnosed and treatment-naïve at the time SARS-CoV-2 infection was documented. The remaining 15 patients had received a median number of 2 previous lines of therapy (range 1-3). Nine (47%) patients were on active chemotherapy at the time of COVID-19 infection. Five were receiving daratumumab combinations, and the 4 remaining patients were on cyclophosphamide, bortezomib and dexamethasone, oral melphalan and dexamethasone, lenalidomide and ixazomib. Relevant concomitant medications were anti-hypertensive drugs in 26% of cases and diuretics in 21%. One patient was on dialysis. COVID-19-related symptoms were fever 11 (58%), cough 8 (42%), anosmia and ageusia. Pneumonia was documented in 10 (53%) patients, 5 of whom had acute respiratory distress syndrome (ARDS) (26%). Four of them were treated with non-mechanical ventilation and one accessed intensive care support. Three of the 5 patients with severe COVID-19 had heart involvement, 2/5 had concomitant heart and kidney involved and 3 was infected while on active chemotherapy. Azytromicin was used in 6 (26%) cases, which was in combination with hydroxycloroquine in 4 of them. Three patients received steroids as treatment for SARS-CoV-2 infection, while anticoagulant therapy was used only in two cases. Lopinavir, tocilizumab and sarilumab were used in one patient each. Four patients (21%) died in the whole cohort. Three had ARDS and one patient died few weeks after the recovery of COVID-19 infection. All deceased patients had heart involvement, 2 were on active therapy (daratumumab plus bortezomib and ixazomib plus dexamethasone). Two patients with kidney involvement at diagnosis, one with ARDS and one with a radiological documented pneumonia treated with non-mechanical ventilation recovered from COVID-19 but developed subsequent worsening of renal function, requiring dialysis in one case.
Conclusions: The fatality rate and the proportion of patients with severe COVID-19 in this series is in the higher range of reports from the general population. Severe SARS-CoV-2 infection can result in renal failure in patients with renal AL amyloidosis.
