Genetic interleukin-6 receptor blockade, chronic disease risk, and longevity: results from the women’s health initiative

Eur J Prev CardiolPublished

  • Prospective cohort study (genetic association)

Authors' conclusion

Genetic IL6R blockade was not associated with incident chronic-disease risk, including invasive cancer and longevity, in a large, ethnically diverse cohort of postmenopausal women.

Study context

Population
Postmenopausal women in the Women's Health Initiative with genotyping information23,464 eligible to survive to 90
Participants
38,807 women
Exposure
IL6R variant carriers vs non-carriers
Outcome
Survival to age 90
Follow-up
Median 20 years

Main finding

As reported in the abstract

Odds ratio

1.00

95% CI 0.91–1.09

2 alleles vs No allele
OR 1.00 (95% CI 0.91–1.09)
Survived to age 90 (whole cohort): 12 181 of 23 464
52.0%

Observational data: associations, not effects.

Further findings

Coronary heart disease (CHD), heart failure (HF), stroke, invasive cancer

Risks did not differ among IL6R variant carriers

High-sensitive C-reactive Protein (hsCRP) ≥2 vs <2 mg/L

Modest increase in all-cause mortality and CHD risk, independent of IL6R carrier status
