ABSTRACT

This paper reports the clinical pharmacist participated in the diagnosis and treatment of a patient with acanthoma caused by nivolumab. This patient developed acanthoma 2 weeks after medication， involving scalp， neck， trunk， back of hand， sole of foot and other parts， with moderate pruritus. The clinical pharmacist determined it as “yes” according to the causality evaluation method of adverse reactions. After reviewing the literature， clinical pharmacists found that acanthoma caused by immune checkpoint inhibitors was more commonly seen in male elderly patients with malignant melanoma， and mainly involved the trunk， extremities and hands. Under the general principle of considering the effectiveness， safety， economy and accessibility of therapeutic drugs， the clinical pharmacist finally decided to give the patient a comprehensive treatment scheme of Halometasone cream for external use + oral administration of Retinoic acid capsules + oral administration of Ebastine tablets after discussion with the doctor， with maximum respect for the patient’s wishes，and continued to use navulizumab for immunotherapy. At the same time， pharmaceutical care and psychological counseling were conducted by clinical pharmacist. Finally， the patient successfully completed the treatment， and the acanthoma gradually subsided after the end of navulizumab treatment. The diagnosis and treatment process of this patient indicated that the participation of clinical pharmacists is helpful to improve the continuity and safety of immunotherapy.
