Acute phase protein precipitating sonatic C-polysaccharide of pneumococci appears in serum of women under treatment with hormonal contraceptives in a significantly higher number of cases when compared with control groups. The summarized results of three preliminary studies show that in 80 control serums there were four positive specimens (5 percent) and in 80 serums from women using hormonal contraceptives there were 58 positive specimens (72.5 percent).
