Serum immunoglobulin concentrations, predominantly IgM, were raised in 72% of 39 sudden infant death cases, consistent with a state of prolonged or repeated antigenic stimulation.Anti-antibody was found in cases of sudden death significantly more frequently than in ill but living control infants. It is suggested that anti-antibody might participate in fatal anaphylaxis in such cases.
在39例婴儿猝死病例中,72%的病例血清免疫球蛋白浓度升高,主要是IgM升高,这与长期或反复抗原刺激状态一致。与患病但存活的对照婴儿相比,猝死病例中抗抗体的发现频率显著更高。有人提出,在这些病例中抗抗体可能参与了致命性过敏反应。
