{Abstract}: <B>UNASSIGNED: </B>RegiSCAR validation criteria for drug reaction with eosinophilia and systemic symptoms (DRESS) includes lymphadenopathy, a frequent feature of both tuberculosis (TB) and human immunodeficiency virus (HIV). TB is the most common HIV-associated coinfection. Advanced HIV is associated with lymph node (LN) fibrosis. It is not clear if this negatively affects case validation in HIV-associated DRESS. To answer this question, we designed a prospective descriptive study to assess lymphadenopathy in various combinations of comorbid HIV, TB, and DRESS.<BR><B>UNASSIGNED: </B>We sought to describe the prevalence of DRESS-associated lymphadenopathy and characterize LN quality, size, and distribution in a high HIV-TB burden setting over time.<BR><B>UNASSIGNED: </B>We prospectively and systematically examined LN in 25 consecutive acute DRESS cases hospitalized at a South African tertiary-care center and 10 hospitalized non-DRESS HIV-TB coinfected controls.<BR><B>UNASSIGNED: </B>Fourteen (56%) of 25 patients were HIV infected, with a median (interquartile range) CD4 count of 254 (66-478) cells/mm³, and 7 of 14 were coinfected with TB. Using RegiSCAR criteria, 12 (46%) of 25 were definite DRESS cases, 8 (31%) of 25 probable, and 5 (23%) of 25 possible. Possible cases were excluded in the analysis. Fifteen (75%) of 20 subjects had LN in ≥2 anatomic sites, including all 7 patients with HIV-TB coinfection. In contrast, 1 (20%) of 5 hospitalized non-DRESS HIV-TB coinfected controls had LN. Cervical LN, in 15 (88%) of 17, was most common, followed by axillary (76%) and inguinal (59%). Cervical LN ranged between 1 and 2 cm in size. Among the 8 (32%) of 25 subjects with follow-up data, LN had regressed in all within 6 weeks of stopping the offending drug and initiating TB treatment. There was no correlation with CD4 cell count and LN.<BR><B>UNASSIGNED: </B>Lymphadenopathy is a common feature of acute DRESS, even among HIV-TB-coinfected patients with advanced immunosuppression.
