Abstract:
BACKGROUND: Inflammatory cytokines play an important role in human immune responses to malaria, although the role of these mediators in pathogenesis is unclear. In this study, we evaluated changes in cytokine levels following chemotherapy, and determined whether cytokine levels in serum correlated with the hematological parameters in the Korean vivax malarial patients. METHODS: The study population was composed of 31 patients in Inje University Ilsan Paik Hospital who were diagnosed with Plasmodium vivax infection. Cytokine profiles, including tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-10 levels, were assessed in serum samples obtained from the malaria patients three times, at the time of diagnosis (stage I) and after treatment with hydroxychloroquine (stage II) and primaquine (stage III). The level of each cytokine was measured using commercially available serum-based ELISA kits. Hematological parameters were simultaneously measured using a hematology autoanalyzer. RESULTS: At thetime of diagnosis, the TNF-alpha (mean, 62.9 pg/mL), IL-6 (mean, 45.5 pg/mL), and IL-10 (mean, 237.7 pg/mL) levels in the malaria patients were higher than the reference values. After treatment with hydroxychloroquine, these levels (TNF-alpha, P<0.01; IL-6, P<0.05; IL-10, P<0.01) significantly decreased to near-normal levels. Significant positive correlations were observed among the cytokine levels, but not between the cytokine levels and other hematological parameters. CONCLUSIONS: In this study, TNF-alpha, IL-6, and IL-10 levels increased at the time of diagnosis and rapidly decreased to normal levels after treatment the levels of these cytokines did not correlate with other hematological parameters.
