“…Whether concurrent steroid treatment counteracts the efficacy of CPIs in non-transplanted patients is still an issue of debate, a recent survey suggests that concomitant use of steroids does not necessarily influence the efficacy of CPI treatment. 16 In addition, immunosuppression did not prevent response in four patients (cases 1, 3, 8, and 13, Table 1) and a report has recently shown that preventive treatment with high-dose steroids, intended to avoid CPI-mediated rejection, did not prevent a remarkable response in a kidney transplant recipient. 6 Therefore, although reduction of immunosuppression to sub-therapeutic doses was not associated with organ rejection, 7,10,17 pre-treatment with steroids could be attempted in the absence of contraindications and immunosuppression tapered during the course of treatment whenever possible.…”
