A systematic review and meta-analysis of myelosuppression in pediatric patients treated with linezolid for Gram-positive bacterial infections

Description
Summary:The incidence of linezolid-induced myelosuppression in pediatric patients was reported at large difference among prospective studies, with a range of 0–24%. Additionally, there is little study which evaluated the impact of linezolid administration period on myelosuppression in pediatric patients, while it is one of the most frequent reason that linezolid therapy has to be discontinued in adult patients. Here, we performed a systematic review and meta-analysis to reveal the incidence of linezolid-induced thrombocytopenia and anemia, and impact of the administration period of linezolid on myelosuppression based on individual data analysis of pediatric patients. We systematically searched the Scopus, EMBASE, Cochrane Central Register of Controlled Trials, PubMed, and CINAHL until April 2020. We investigated the incidence of linezolid-induced thrombocytopenia and anemia using pooled analysis, and evaluated the impact of linezolid administration period on myelosuppression using meta-analysis. Thirteen studies with 969 pediatric patients were identified. The pooled incidences of thrombocytopenia and anemia were 9% (95% confidence interval (CI), 3–18%) and 4% (95% CI, 0–12%), respectively. Our meta-analysis showed the extension of linezolid administration period (more than 14 days) resulted in higher incidence of thrombocytopenia (OR 4.86, 95% CI 1.10–21.55) and anemia (OR 4.57, 95% CI 0.13–160.49). The incidence of linezolid-induced myelosuppression in pediatric patients was less than 10%. However, our meta-analysis revealed linezolid administration period for more than 14 days was one of risk factors associated with linezolid-induced myelosuppression. Therefore, especially for pediatric patients treated with linezolid for more than 14 days, careful monitoring of myelosuppression is required.
