title: Serum levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and interleukin-1 beta (IL-1 beta) in dengue-infected patients.
abstract: Sensitive immunoenzymatic assays were used to study the levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and IL-1 beta in sera from dengue-infected patients obtained during the 1989-1990 outbreak of dengue-3 in Tahiti, French Polynesia. The patients, both children (n = 47) and adults (n = 18), were clinically classified as having dengue hemorrhagic fever (DHF) and graded according to the severity of illness (grade I = fever, grade II = fever with spontaneous hemorrhagic manifestations, grade III = circulatory failure, grade IV = deep shock). The serum samples were obtained from day 1 to day 10 after the onset of the disease. High levels of TNF-alpha were observed in dengue-infected children of all severity grades. The highest values of TNF-alpha were found before day 6 after the onset of the infection, these values decreased from day 6 to day 10. The highest values were observed in sera from grade III and IV patients. High values of IL-6 were observed in serum samples of grade I and II patients on day 1, which decreased on day 4, and by day 5 were similar to those obtained from 25 control children. In grade III and IV patients, the highest values of IL-6 were observed from day 3 to day 5 after the onset of infection; after day 5, these values were very low.(ABSTRACT TRUNCATED AT 250 WORDS)
