    To assess the relevance of genetically determined host factors for the prognosis of meningococcal disease, Fc gamma receptor IIA (FcγRIIA), the tumor necrosis factor alpha (TNF-α) 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 FcγRIIA, TNF-α, and PAI-1 alleles was not significantly different between patients and controls. Patients with the FcγRIIA-R/R 131 allotype scored ≥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-α and PAI-1 polymorphisms were not. © Springer-Verlag 2004.
