[Genetic study of predisposition to community-acquired pneumonia].

The study included 243 patients with acute community-acquired pneumonia and 173 healthy subjects. The following candidate loci were used to investigate genetic variability: 3 sites of CYP1A1, GSTM1, GSTT1, GSTP1, ACE gene of the rennin-angiotensin system, chemokine receptor gene CCR5. Enhanced predisposition to pneumonia was shown to be characteristic of homozygotes in deletion at the ACE locus (OR = 1.8; p = 0.013), carriers of normal alleles of the GSTM1 locus (OR = 1.7; p = 0.010), and homozygotes in allele 606T of the CYP1A1 gene (OR = 1.6; p = 0.020).
