To assess the relevance of genetically determined host factors for the prognosis of meningococcal disease, Fc gamma receptor IIA (FcgammaRIIA), the tumor necrosis factor alpha (TNF-alpha) gene promoter region, and plasminogen-activator-inhibitor-1 (PAI-1) gene polymorphisms were studied in 145 patients with meningococcal disease and in 290 healthy controls matched by sex. Distribution of FcgammaRIIA, TNF-alpha, and PAI-1 alleles was not significantly different between patients and controls. Patients with the FcgammaRIIA-R/R 131 allotype scored > or =1 point in the Barcelona prognostic system more frequently than patients with other allotypes (odds ratio, 18.6; 95% confidence interval, 7.1-49.0, P<0.0001), and they had a higher risk of sequelae (odds ratio, 3.5; 95% confidence interval, 1.1-11.7; P=0.03). Fc gamma receptor IIA polymorphism was associated with markers of disease severity, but TNF-alpha and PAI-1 polymorphisms were not.
