Abstract
Objective: To determine the importance of IgM antibodies against phosphorylcholine ( aPC), a novel protective factor for cardiovascular disease ( CVD), in a population with a non-western life style as compared with a Swedish control group. Methods and results: Risk factors for cardiovascular disease were determined in a group of 108 individuals aged 40-86 years from New Guinea and 108 age-and sex-matched individuals from a population based study in Sweden. Antibodies were tested by ELISA. aPC IgM levels were significantly higher among New Guineans than among Swedish controls ( p < 0.0001). This difference remained significant among both men and women when controlled for LDL and blood pressure which were lower and smoking which was more... (More)
Objective: To determine the importance of IgM antibodies against phosphorylcholine ( aPC), a novel protective factor for cardiovascular disease ( CVD), in a population with a non-western life style as compared with a Swedish control group. Methods and results: Risk factors for cardiovascular disease were determined in a group of 108 individuals aged 40-86 years from New Guinea and 108 age-and sex-matched individuals from a population based study in Sweden. Antibodies were tested by ELISA. aPC IgM levels were significantly higher among New Guineans than among Swedish controls ( p < 0.0001). This difference remained significant among both men and women when controlled for LDL and blood pressure which were lower and smoking which was more prevalent in New Guineans as compared to Swedish controls ( p < 0.0001). aPC IgM was significantly and negatively associated with age and systolic blood pressure among Swedish controls and with waist circumference among New Guineans. aPC IgM levels were significantly higher among women than men in both groups. The proportion of the saturated fatty acid ( FA) myristic acid in serum cholesterol esters was negatively but polyunsaturated eicosapentaenoic acid and also lipoprotein ( a) were positively associated with aPC IgM levels. Conclusion: IgM-antibodies against PC, which have atheroprotective properties, are higher in a population from Kitava, New Guinea with a traditional lifestyle, than in Swedish Controls, and higher among women than men in both populations tested. Such antibodies could contribute to the low incidence of cardiovascular disease reported from Kitava and could also provide an explanation as to why women have a later onset of CVD than men. (Less)
