Delayed-type hypersensitivity in classic Kaposi sarcoma patients and controls
2011
Background: Immune perturbation likely affects the development of Kaposi sarcoma (KS) among people infected with the KS-associated herpesvirus (KSHV). We tested whether KSHV-seropositive individuals or cases of classic KS (cKS), which typically originates in the leg, had differing delayed-type hypersensitivity (DTH) in the forearm or leg. Methods: Mantoux DTH with three antigens (Candida, tetanus, PPD) was performed on the forearm and leg of 15 cKS cases, 14 KSHV-positives without KS, and 15 KSHV-negative controls. The diameters of induration responses were compared by group and body site. Results: Leg DTH was greater than forearm DTH among controls (mean difference 5.6 mm, P=0.0004), where…
Risk of classic Kaposi sarcoma with exposures to plants and soils in Sicily
2010
Abstract Background Ecologic and in vitro studies suggest that exposures to plants or soil may influence risk of Kaposi sarcoma (KS). Methods In a population-based study of Sicily, we analyzed data on contact with 20 plants and residential exposure to 17 soils reported by 122 classic KS cases and 840 sex- and age-matched controls. With 88 KS-associated herpesvirus (KSHV) seropositive controls as the referent group, novel correlates of KS risk were sought, along with factors distinguishing seronegatives, in multinomial logistic regression models that included matching variables and known KS cofactors - smoking, cortisone use, and diabetes history. All plants were summed for cumulative exposu…
