Literature analysis of aplastic anemia/pure red cell aplasia induced by pembrolizumab
To analyze the clinical characteristics of aplastic anemia (AA)/pure red cell aplasia (PRCA) induced by pembrolizumab, and provide reference for clinical safe drug use.
METHODS
2
Using search terms as “pembrolizumab”, “keytruda”, “anemia” and “aplastic anemia” in both Chinese and English, the literature related to AA/PRCA induced by pembrolizumab were retrieved from PubMed, Embase, CNKI, Wanfang and VIP databases, and then analyzed descriptively and statistically.
RESULTS
2
A total of 10 patients were included from 10 literature; among these 10 patients, there were 5 males and 5 females, with 5 patients being aged 65 or above. The primary disease was mainly metastatic melanoma (4 cases). AA/PRCA occurred 13 d-3 years after the first dose of pembrolizumab. The main clinical manifestations included fatigue, dyspnea, oral/nasal bleeding, diffuse purpura, etc.; 8 cases developed moderate anemia and 2 cases developed severe anemia. After discontinuation and receiving supportive therapy, 5 cases improved, 1 case worsened in anemia, and 4 cases died.
CONCLUSIONS
2
When using pembrolizumab in clinical practice, blood routine should be regularly monitored. When AA/PRCA and other related symptoms occur, pembrolizumab should be stopped in time and a therapy regimen should be formulated according to the patient’ condition, to ensure the safety of medication.
