国内外学者认为肺炎可继发地引起小儿免疫(细胞免疫及体液免疫)功能不全。有的学者指出,1岁以内小儿可因频繁或大量抗原刺激,使个别免疫细胞功能衰竭。一般认为,甾体激素——泼尼松、氢化可地松、以及氟美松等对小儿特异性及非特异性免疫功能亦有一定干扰。至于甾体激素类药物对免疫功能低下肺炎患儿是否能使其免疫功能继续低下 Domestic and foreign scholars think that pneumonia can cause children’s immune (cellular immunity and humoral immunity) secondary failure. Some scholars pointed out that children under the age of 1 can be frequent or large amounts of antigen stimulation, so that individual immune cell failure. It is generally believed that steroid hormones - prednisone, hydrocortisone, and dexamethasone and other specific and non-specific immune function in children also have some interference. As for steroid hormone drugs in children with immunocompromised pneumonia can make their immune function continues to be low
