This study was performed to assess the possible involvement of humoral immunity in essential hypertension, independently of the presence of atherosclerotic disease, which in turn may be associated with immunologic changes. Sixty-five patients without demonstrated atherosclerotic disease were selected according to clinical and arteriographic criteria, including 23 hypertensive subjects (all pharmacologically treated) and 42 controls. Mean ages (58.7 +/- 8.3(1 S.D.) years in the controls and 57.7 +/- 7.9 years in the hypertensive subjects) and sex distribution were similar in the 2 groups. Of the main risk factors, atherosclerosis, smoking, diabetes, total cholesterol and HDL-cholesterol were equivalent, while triglycerides were higher in the hypertensive subjects than in the controls (142.6 +/- 52.7 vs. 112.6 +/- 67.7 mg/dl; p = 0.0065). In these subjects' sera the immunoglobulins IgG, IgA and IgM, and the third and fourth complement components (C3 and C4) were measured. Of these variables, only C3 was higher in the hypertensive subjects than in the controls (124.3 +/- 29.3 vs. 107.8 +/- 18.4 mg/dl; p = 0.0183). Furthermore, C3 was significantly correlated with triglycerides (tau = 0.3613; p < 0.0001), but the association with hypertension was confirmed only for C3, and not for triglycerides, by multiple logistic regression (p = 0.0142). The increase in serum C3 suggests the possible implication of humoral immunity in the pathogenesis or progression of essential hypertension.

Abstract

This study was performed to assess the possible involvement of humoral immunity in essential hypertension, independently of the presence of atherosclerotic disease, which in turn may be associated with immunologic changes. Sixty-five patients without demonstrated atherosclerotic disease were selected according to clinical and arteriographic criteria, including 23 hypertensive subjects (all pharmacologically treated) and 42 controls. Mean ages (58.7 +/- 8.3(1 S.D.) years in the controls and 57.7 +/- 7.9 years in the hypertensive subjects) and sex distribution were similar in the 2 groups. Of the main risk factors, atherosclerosis, smoking, diabetes, total cholesterol and HDL-cholesterol were equivalent, while triglycerides were higher in the hypertensive subjects than in the controls (142.6 +/- 52.7 vs. 112.6 +/- 67.7 mg/dl; p = 0.0065). In these subjects' sera the immunoglobulins IgG, IgA and IgM, and the third and fourth complement components (C3 and C4) were measured. Of these variables, only C3 was higher in the hypertensive subjects than in the controls (124.3 +/- 29.3 vs. 107.8 +/- 18.4 mg/dl; p = 0.0183). Furthermore, C3 was significantly correlated with triglycerides (tau = 0.3613; p < 0.0001), but the association with hypertension was confirmed only for C3, and not for triglycerides, by multiple logistic regression (p = 0.0142). The increase in serum C3 suggests the possible implication of humoral immunity in the pathogenesis or progression of essential hypertension.
