Abstract
This study aimed to estimate the prevalence and analyze the risk factors for linezolid-induced hematological side effects in multidrug-resistant tuberculosis (MDR-TB) patients. Data were collected from medical records of MDR-TB patients who received linezolid between January 2018 and May 2020. Statistical significance analysis and multivariate analysis were performed with SPSS version 24 software. Hematological side effects were identified in 27 out of 93 patients (29.0%). The most prevalent effect was anemia (29.0%), while the less prevalent effects were thrombocytopenia (3.2%) and leukopenia (2.2%). These side effects were reported after 2weeks of linezolid treatment. The drug dose was more than 11mg/kgBW/day or patient weighing less than 54kg was identified as an independent risk factor for anemia in multivariate analysis. Anemia was the most prevalent of linezolid-induced hematological side effects in MDR-TB patients. Therefore, hemoglobin monitoring might be recommended in patients weighing less than 54kg and after receiving linezolid therapy for at least 2weeks.
