Regulated transcripts were analyzed in plasma by enzyme immunoassays (chemokines) and in whole blood by quantitative polymerase chain reaction (receptors) from patients with scrub typhus (n = 129), patients with similar febrile illness without O tsutsugamushi infection (n = 31), and healthy controls (n = 31).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>cDNA microarray identified dysregulation of the chemokines CCL18 and CCL23 and the receptor CCR3 in severe scrub typhus. Plasma CCL7 (a ligand for CCR3), CCL18, and CCL23 were higher in patients with scrub typhus, with a decline during follow-up. Conversely, mRNA levels of CCR3 and CCR8 (the receptor for CCL18) were decreased in whole blood at hospital admission, followed by an increase during follow-up. CCL7 was independently associated with disease severity. Admission CCL7 levels were associated with short-time mortality.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n
