Tumor necrosis factor inhibitor therapy and myocardial infarction risk in patients with psoriasis, psoriatic arthritis, or both.

Abstract

OBJECTIVES:

To stratify MI risk reduction in those treated with a TNF inhibitor for psoriasis only, psoriatic arthritis only, or both psoriasis and psoriatic arthritis.

DESIGN:

Retrospective cohort study.

SETTING:

Between January 1, 2004 and November 30, 2010.

PARTICIPANTS:

At least 3 ICD9 codes for psoriasis (696.1) or psoriatic arthritis (696.0) (without antecedent MI.

INTERVENTION:

None

MAIN OUTCOME MEASURE:

Incident MI.

RESULTS:

When comparing to those not treated with TNF inhibitors (reference group), of those treated with TNF inhibitors: those with psoriasis only (N= 846) had a significant decrease in MI risk (hazard ratio (HR), 0.26; 95% CI, 0.12-0.56); those with psoriatic arthritis only (N= 112) had a non-significant decrease in MI risk (HR, 0.86; 95% CI, 0.28-2.70); those with both psoriasis and psoriatic arthritis (N= 715) had a non-significant decrease in MI risk (HR, 0.76; 95% CI, 0.47-1.24).

CONCLUSIONS:

In the TNF inhibitor cohort, those with psoriasis only have the strongest association with MI risk reduction, followed by those with psoriatic arthritis only, and then followed by those with both psoriasis and psoriatic arthritis.
