Most studies investigating the association between psoriasis and cardiovascular disease have shown a significant relationship. This comparison study investigated the association between psoriasis and prevalent use of cardiovascular drugs. Drug exposure data for 1998 to 2006 were extracted from the Dutch PHARMO-Record Linkage System database. Psoriasis patients were selected using an algorithm of hospitalization and drug dispensing records specific for psoriasis and matched with controls for gender, age and time-period. From the records of 2.5 million Dutch residents, 9,804 (0.4%) psoriasis patients and 15,288 (0.6%) controls were selected. Psoriasis patients used significantly more anti-hypertensives, anti-coagulant and anti-platelet agents, digoxin, nitrates, lipid-lowering and anti-diabetic drugs than the reference population during a 5-year period observation. In a multiple linear regression model adjusting for the number of unique drugs used, psoriasis was no longer significantly associated with any of these drug classes. Psoriasis patients used more cardiovascular-related drugs, but surveillance bias appears to affect this association considerably.
