Allergic transfusion reactions (ATRs), particularly those caused by plasma-rich platelet concentrates (P-PCs), are an important concern in transfusion medicine. Replacing P-PCs with PCs containing M-sol (M-sol-R-PCs) is expected to prevent ATRs. However, this has not yet been verified by sufficient clinical evidence.
Study Design and Methods
A retrospective cohort study was performed between 2008 and 2011. Pediatric patients with hematologic disorders, solid tumors, primary immunodeficiency disorders, or inherited metabolic disorders were transfused with M-sol-R-PCs between 2010 and 2011; the transfusions of P-PCs administered between 2008 and 2011 were compared in terms of frequency and severity of ATRs, corrected count increment (CCI), and occurrence of bleeding. Data were collected for 6 consecutive months on a per-patient basis.
Data obtained during 2008 to 2011 showed that of the 78 patients receiving 515 P-PC transfusions, 14 (17.9%) had 17 ATRs (3.3%); 14 and three ATRs were of Grades 1 and 2, respectively. In 2010 to 2011, 49 patients received 620 transfusions of M-sol-R-PCs, and two patients (4.1%) had Grade 1 ATRs (0.3%). Thus, the frequency of ATRs per bag and per patient differed significantly between the two transfusions. No steroid agents were used for the prevention or treatment of ATRs in the M-sol-R-PC group. The CCI (24 hr) for M-sol-R-PCs did not differ from that for P-PCs.
M-sol-R-PCs were found to be effective in preventing ATRs without loss of transfusion efficiency in children; however, its efficacy should be further evaluated in prospective clinical trials.
