We reported earlier association of hsCRP and IL-6 with C. pneumoniae IgA serology in CAD patients [14, 15], however, there is no study where levels of these plasma circulatory markers in C. pneumoniae IgA positive and hsCRP positive groups of CAD patients have been evaluated which is required for understanding pathogenesis of CAD. The gene discussed is CD79A; the disease is coronary artery disorder.
