Task: Intent Identification
Input (English): Heat shock protein (HSP)70-2 is an important immunomodulatory protein induced in response to inflammatory stimuli. We assessed whether HSP70-2+1267 genotype influenced the risk of septic shock in a prospective cohort study of community-acquired pneumonia and whether HSP70-2+1267 genotype is a better predictor of septic shock than the genotype at lymphotoxin-alpha +250.', 'Prospective cohort study.', 'A large, nonprofit, private hospital system in Memphis, TN.', 'Adults admitted with community-acquired pneumonia between 1998 and 2001. Septic shock was defined according to consensus criteria (American College of Chest Physicians/Society of Critical Care Medicine, 1992).', 'Blood sampling.', 'A total of 343 subjects were enrolled; 30 had septic shock. HSP70-2+1267 and lymphotoxin-alpha +250 genotype was determined using polymerase chain reaction and restriction enzyme digestion. HSP70-2+1267 AA genotype was the strongest predictor of septic shock (p =.0005; relative risk, 3.5). Lymphotoxin-alpha +250 AA genotype was also associated with an increased risk of septic shock (p =.002; relative risk, 2.7). Logistic regression analysis found only age (p =.04) and HSP70-2+1267 genotype (p =.006) were predictors of septic shock. The greatest risk of septic shock was associated with carriage of the HSP70-2+1267 A/lymphotoxin-alpha +250 A haplotype (p <.0001).
