However, little is known about statin use and dengue severity in adult dengue patients with hyperlipidemia. We conducted a retrospective cohort study from 2004\u20132008 and 2012\u20132013 in Tan Tock Seng Hospital, Singapore on adult dengue patients with hyperlipidemia, comparing those with and without statin usage at hospitalization in terms of primary outcome of dengue hemorrhagic fever (DHF) or shock syndrome (DSS), and severe dengue (SD). Of 13,975 subjects screened, 257 dengue patients were included; 191 (74.3%) were statin users and 66 (25.7%) were non-users. Compared with non-users, statin use was not associated with decreased risk of DHF\/DSS (adjusted risk ratio [aRR]\u2009=\u20090.66, 95%confidence interval [CI]: 0.41\u20131.08, P\u2009=\u20090.10) and SD (aRR\u2009=\u20091.43, 95%CI: 0.84\u20132.43, P\u2009=\u20090.19).
