Adenosine 5’monophosphate-activated protein kinase activation reduces the risks of psoriasis and its comorbidities: a Mendelian randomization study in the UK Biobank

Rheumatology (Oxford)Published Mendelian randomization study

Authors' conclusion

AMPK activation may protect against LOPs and associated ischemic heart disease in men.

Study context

Population
UK Biobank participants; psoriasis split into early-onset and late-onset at 60 years9,126 EOP and 3324 LOP
Participants
407,159 participants
Comparison
Higher vs lower AMPK genetic risk score
Outcome
Risk of psoriasis (early-onset and late-onset), its comorbidities and mortality
Methodological detailsUK Biobank, genetic instrument of 44 HbA1c-associated SNPs as proxy for AMPK genetic risk score, log-binomial models

Performance

As reported in the abstract

Late-onset psoriasis in men, per AMPK genetic risk score

RR (95% CI 1.022-1.236); 12.4% increase in LOP risk in men

1.124

Further findings

Ischaemic heart disease in male psoriasis patients, per AMPK genetic risk score

RR
1.217 (95% CI 1.062-1.395)
