BAYRAM, Nuri et al. Linezolid-related adverse effects in clinical practice in children. Arch. argent. pediatr. [online]. 2017, vol.115, n.5, pp.470-475. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2017.470.

Introduction: Linezolid may cause adverse effects such as thrombocytopenia, which were found to be dependent on receiving linezolid for longer than 2 weeks. There are limited studies concerning the safety and timing of linezolid-related adverse effects in children. Objective of this study was to evaluate the incidence of adverse effects associated with linezolid, with especially focusing on the time of occurrence. Population and Methods: All children (<18 years of age) who received >3 days of linezolid therapy were included in this study. Adverse effects attributed to linezolid and time of occurrence of side effects was evaluated. Results: A total of 179 children were enrolled to the study. The patients' median age was 4 years (6 days to 17 years). During linezolid treatment, 36 (20.1%) patients experienced adverse effects. The most common adverse effect was thrombocytopenia that was detected in 26 patients (14.5%). Other adverse effects were as following; elevated liver enzymes in 4 patients, leucopenia and anemia in 2 patients, renal function impairment in one patient, and serious skin reactions in 3 patients. Adverse effects were detected within median 7.5 days of therapy (ranging from 4 to 18 days). Among 36 patients, 26 (72.2%) patients had adverse effect on the first 10 days of therapy. Conclusions: Transient adverse effects were detected in 20.1% of the patients during linezolid therapy. These adverse effects may be detected earlier than ten days of treatment. Linezolid should be prescribed safely in children with monitoring adverse effects especially platelet count and level of liver enzymes.
