Cyclosporine successfully treats steroid-resistant checkpoint inhibitor-related pneumonitis: a case report

This marks the first instance of effectively managing steroid-resistant CIP through the combined use of cyclosporine and corticosteroids. Presently, cases of steroid-resistant CIP remain infrequent, necessitating vigilant and meticulous monitoring within clinical settings. Notably, there exists no distinct guideline specifying a singular agent for rescuing patients unresponsive to corticosteroid therapy. Therefore, cyclosporine emerges as a promising and efficacious treatment alternative for individuals unresponsive to corticosteroid intervention in the context of CIP.
