Abstract
We thank Luigi Petramala and Claudio Letizia for their comment1 on our letter about the possible role of sacubitril/valsartan in patients with coronavirus disease 2019 (COVID-19).2 The authors rightly affirm the need for continuing previous therapies with angiotensinconverting enzyme inhibitors (ACE-Is) or sartans in patients with COVID-19, as outlined by recent international consensus papers.3 There is no definite evidence about the harmful or protective use of ACE-Is/sartans in COVID-19 patients.4,5 Dedicated, randomized controlled trials are needed in order to verify the possible worsening of lung infection and/or systemic involvement in patients with COVID-19 who are chronically treated with ACE-Is/sartans. Furthermore, we do not intend to pressurize the indiscriminate change of previous treatments towards sacubitril/valsartan in the absence of evidence from randomized trials.
