BACKGROUND: Platelet transfusion refractoriness (PTR) remains an intractable issue in clinical practice, and is common in hematological patients. At present, it is believed that both immune and non-immune factors play a role. We conducted a meta-analysis of various risk factors which may contribute to PTR.
METHODS: PubMed, Embase, Cochrane library, and Web of Science were selected as research database platforms. Citations included were further assessed for quality and bias using the Newcastle-Ottawa Scale. All analyses were performed using Review Manager Version 5.4 and STATA 16.0.
RESULTS: The preliminary search revealed 1069 publications, and 17 (5929 patients in total) were ultimately included in the quantitative analysis. The following variables were associated with the occurrence of PTR: fever (OR = 2.26, 95%CI 2.00-2.55, p < 0.00001), bleeding (OR = 2.10, 95%CI 1.36-3.24, p = 0.0008), female sex (OR = 2.06, 95%CI 1.13-3.75, p = 0.02), antibiotic use (OR = 2.94, 95%CI 1.54-5.59, p = 0.001), and infection (OR = 2.19, 95%CI 1.20-4.03, p = 0.01). Antibodies involved in immune activation were a higher risk factor (OR = 4.17, 95%CI 2.36-7.36, p < 0.00001), and splenomegaly was nearly significant (OR = 1.73, 95%CI 0.97-3.07, p = 0.06).
CONCLUSIONS: We identified some important risk factors for PTR, but further research is needed to identify the many other possible elements that may contribute to or mediate PTR.
