We have read with interest the letter by Kaklamanos et al1 pertaining to our COVID-19 High-intensity Immunosuppression in Cytokine storm syndrome (CHIC) study.2 Kaklamanos et al share their positive experience with tocilizumab administered to three patients with severe COVID-19 pneumonia, accompanied by signs of hyperinflammation, as described in our CHIC study.1 These descriptions perfectly match with our clinical experience regarding the use of tocilizumab in such critically ill patients and mirror the patients we have described in our CHIC study.2 Fortunately, the benefits of tocilizumab in such patients have meanwhile also been confirmed in randomised controlled trials, which hopefully paves the way, although with significant delay, for a more widespread use in COVID-19 patients who need it.3–5
