Roxithromycin Treatment of Tsutsugamushi Disease (Scrub Typhus) in Children

Park, Hye Jin; Lee, Kyung Yil

Abstract

PURPOSE
Although chloramphenicol and doxycycline have been used for the treatment of tsutsugamuchi disease, a difficulty exists in determining which drugs to use in treating children because of potential complications such as aplastic anemia or teeth discoloration. We evaluated the effect of roxithromycin, a macrolide antibiotic, on tsutsugamushi disease in children.
METHODS
A retrospective analysis was conducted on 39 children with tsutsugamuchi disease(scrub typhus) who were treated with doxycycline(DC), chloramphenicol(CM), or roxythromycin(RM) between 1991 and 2000. We divided the patients into a DC-treated group(DC group; 16 children), a CM-treated group(CM group; 14 children), and RM-treated group(RM group; 9 children) and compared these groups.
RESULTS
Most cases(97%) developed in October and November. Fever and rash were observed in all 39 cases and an eschar was noted in 36 cases(92%). No statistical differences could be found between the three groups in mean age, duration of fever before admission, white blood cell(WBC) count, and complications including abnormal liver enzymes. In most cases defervescence after treatment was within 24 hours(34 cases, 87%), and during 24-48 hours in two cases in the DC group, one in the CM group, and two in the RM group(no statistical difference).
CONCLUSION
Roxythromycin was as effective as conventional doxycycline or chloramphenicol, in children with scrub typhus and may be safer to use.
