Introduction: Common variable immunodeficiency and X-linked agammaglobulinaemia are primary immunodeficiencies classified as antibody deficiencies, and they both result in hypogammaglobulinaemia.
Objective: Evaluate the lipid profile and other cardiovascular risk biomarkers in CVID and XLA patients.
Methods: In total, 24 patients and 12 healthy controls matched by age and gender were included in the study. We evaluated anthropometric measurements, and seric total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), apo A-I, small dense LDL (sdLDL), C-reactive protein (CRP), and tumour necrosis factor alpha (TNF-alpha), myeloperoxidase (MPO), cholesteryl ester transfer protein (CETP), and lecithin cholesterol acyltransferase (LCAT) were assessed.
Results: CRP (p = 0.008) and TNF-alpha (p < 0.001) concentrations were significantly higher, whereas HDL-c (p = 0.025) and apo A-I (p = 0.013) levels were significantly lower in patients than in the controls. In the patient group, a negative and significant correlation was observed between HDL-c and TNF-alpha (r = -0.406; p = 0.049) and between HDL-c and TG (r = -0.641; p = 0.001).
Conclusion: Common variable immunodeficiency and X-linked agammaglobulinaemia patients presented themselves with increased inflammatory markers associated with a decreased HDL-c and apo A-I levels, which can predispose to a high cardiovascular risk.
