BackgroundSolitary cysticercus granuloma (SCG) of the brain is the most common type of neurocysticercosis in India. In this study, we evaluated TLR4 polymorphisms in patients with SCG.MethodsOne-hundred-forty-three patients with SCG and 134 controls were enrolled. Assessment for TLR4 Asp299Gly and Thr399Ile polymorphism was done. TLR4 genotype was determined by PCR-sequencing chain termination method. The patients were followed for 6 months.ResultsAsp/Gly (P = 0.024) and Thr/Ile (P = 0.004) genotypes were significantly associated with the SCG. The Gly (Asp/Gly plus Gly/Gly) genotype (P = 0.025) and Ile (Thr/Ile plus Ile/Ile) genotype (P = 0.008) were significantly associated with the SCG. Gly/Gly and Ile/Ile genotypes were not significantly associated with SCG (P = 0.767 for Gly/Gly, P = 0.936 for Ile/Ile). At 6 months, TLR4 299Asp/Gly (P = 0.02) and 399Ile/Thr (P = 0.023) polymorphisms were significantly associated with the calcification or persistence of SCG.ConclusionsTLR4 polymorphisms are associated with the susceptibility to infection with SCG.
