Abstract

BACKGROUND AND PURPOSE: The C-C chemokine receptor 5-Δ32 deletion (CCR5-Δ32) has been associated with lower levels of C-reactive protein (CRP), but the effect on cardiovascular diseases is uncertain. This study addresses the impact of CCR5-Δ32 on the risk of low-grade inflammation and hospitalization with cardiovascular diseases in a large cohort of blood donors.

METHODS: Genotyping of 15,206 healthy participants from The Danish Blood Donor Study for CCR5-Δ32 was performed and combined with CRP measurements and questionnaire data. Cardiovascular disease diagnoses were identified by ICD-10 codes in the Danish National Patient Registry.

RESULTS: CCR5-Δ32-carriers had a higher risk of hospitalization for cardiovascular diseases when compared with wild-type homozygotes (hazard ratio = 1.35, 95%-confidence interval: 1.00-1.87). CRP levels were unaffected by the CCR5-Δ32 deletion.

CONCLUSION: In this cohort, carriers of the CCR5-Δ32 deletion had normal CRP levels but a borderline significant increased risk of cardiovascular diseases.
