Correlations of IL-6 and CRP gene polymorphisms with pulmonary heart disease.Eur Rev Med Pharmacol Sci 2019; 23(18):8109-8114ER
To explore the correlations of interleukin-6 (IL-6) and C-reactive protein (CRP) gene polymorphisms with pulmonary heart disease (PHD).
PATIENTS AND METHODS
A total of 98 patients with PHD and 102 healthy persons receiving physical examinations were enrolled. Their general clinical information was collected, and the levels of IL-6 and CRP in the plasma were determined. The pulmonary functions and blood gas were detected, and the TaqMan-minor groove binder (MGB) probe was used to detect the polymorphisms of IL-6 rs1800796 and CRP rs1800796.
Observation group had higher levels of IL-6 and CRP than control group (p<0.05). The forced expiratory volume in 1 second (FEV1) (%), FEV1/forced vital capacity (FVC) ratio (%), and arterial partial pressure of oxygen (PaO2) in observation group were lower than those in control group (p<0.05), but the arterial partial pressure of carbon dioxide (PaCO2) was higher than that in control group (p<0.05). There were differences in the distribution frequencies of the genotypes and alleles of IL-6 rs1800796 and CRP rs1800796 between the two groups (p<0.05).
IL-6 and CRP are correlated with the onset of PHD, and there are also correlations between the polymorphisms of IL-6 rs1800796 and CRP rs2794521 and the disease.
