RESEARCH HIGHLIGHTS Research Highlights Jennifer Tran, Patrick Fleming, Cathryn Sibbald SATELLITE LESIONS: A NEW PROGNOSTIC SIGN FOR systemic symptoms (fever, malaise, lymphadenopathy, HIGH-RISK HERPES ZOSTER and/or headache), underlying immunosuppression, and el Hayderi, L., Bontems, S., Nikkels-Tassoudji, N., Arrese, J. E., Seidel, L., need for hospitalization. Meex, C., & Nikkels, A. F. (2015). Satellite lesions accompanying herpes zoster: A new prognostic sign for high-risk zoster. The British Journal There were 109 confirmed cases of herpes zoster, of of Dermatology, 172(6), 1530Y1534. which 23 patients (21%) had SLs. Immunocompromised patients had a 3.15-fold increased RR of having SLs and erpes zoster, or shingles, is a painful vesicular were more likely to have higher numbers of SLs compared eruption caused by reactivation of varicella-zoster with immunocompetent patients. SLs were usually located virus (Wilson, 2011). This condition affects almost on the trunk and were not pruritic or painful. The pres- Hone million individuals annually in the United States, with ence of SLs significantly increased risk of systemic signs an estimated lifetime risk of 32% (Harpaz, Ortega-Sanchez, (RR = 2.08, 95% confidence interval [CI] [1.35, 3.30]), & Seward, 2008). Zoster classically affects a single der- underlying immunosuppression (RR = 2.38, 95% CI matome but can occasionally present with satellite lesions [1.46, 3.87]), multistage zoster (RR = 3.30, 95% CI [1.96, (SLs) away from the primary site (Wilson, 2011). Pre- 5.55]), multidermatomal zoster (RR = 10.6, 95% CI [4.72, vious reports have suggested that these SLs may represent 23.8]), increased surface involvement (RR = 3.27, 95% CI hematogenous spread of the virus (Castronovo & Nikkels, [1.89, 5.7]), and hospitalization (RR = 2.94, 95% CI 2012), but the overall clinical significance of these SLs [1.55, 5.58]).
