Comorbidities in lichen planus by phenome-wide association study in two biobank population cohorts.

Background: Lichen planus (LP) is a relatively frequent mucocutaneous inflammatory disease affecting the skin, skin appendages and mucosae, including oral mucosae, and less frequently the anogenital area, conjunctivae, oesophagus or larynx.

Objectives: To estimate the association of LP, with emphasis on dermatological and gastrointestinal conditions, in two large independent population cohorts.

Materials And Methods: We performed a phenome-wide association study (PheWAS) and examined conditions associated with LP in two unrelated cohorts, i.

Common genetic loci influencing plasma homocysteine concentrations and their effect on risk of coronary artery disease.

Background: The strong observational association between total homocysteine (tHcy) concentrations and risk of coronary artery disease (CAD) and the null associations in the homocysteine-lowering trials have prompted the need to identify genetic variants associated with homocysteine concentrations and risk of CAD.

Objective: We tested whether common genetic polymorphisms associated with variation in tHcy are also associated with CAD.

Design: We conducted a meta-analysis of genome-wide association studies (GWAS) on tHcy concentrations in 44,147 individuals of European descent.

C-reactive protein modifies the association of plasma leptin with coronary calcium in asymptomatic overweight individuals.

Evidence suggests putative interactions of leptin and C-reactive protein (CRP) in the pathogenesis of adiposity-related atherosclerotic cardiovascular disease (CVD). Therefore, we investigated whether CRP levels modify the relationship of leptin levels with coronary artery calcium (CAC). We examined 1,460 asymptomatic individuals from two community-based cross-sectional studies coordinated at a single, university-based research center.
