We describe a patient with hypergammaglobulinaemic purpura and show that the serum contains IgG and IgA immune complexes sedimenting between IgM and IgG on ultracentrifugation. The complexes containing IgG were markedly temperature dependent. A drop in temperature from 37 degrees C to 28 degrees C gave a seventeen-fold increase in the quantity of these complexes. This temperature dependency may be an important factor in localizing the major pathological manifestation of this disease to the skin.
我们描述了一位患有高球蛋白血症性紫癜的患者,并表明其血清中含有IgG和IgA免疫复合物,在超速离心时这些复合物沉降于IgM和IgG之间。含有IgG的复合物明显依赖温度。温度从37℃降至28℃会使这些复合物的量增加17倍。这种温度依赖性可能是将该疾病的主要病理表现定位于皮肤的一个重要因素。
