A relationship between the induction of hypertriglyceridemia by cytokines and the cachexia seen in chronic infection has been proposed by other investigators. Since patients with the acquired immunodeficiency syndrome (AIDS) often experience progressive tissue wasting, we decided to examine serum lipid levels and body cell mass in patients with AIDS.
Serum lipid levels and body cell mass were measured in 32 patients with the acquired immunodeficiency syndrome (AIDS), eight asymptomatic subjects who were anti-human immunodeficiency virus (HIV) antibody positive, and 17 heterosexual and homosexual control subjects who did not have antibodies to HIV.
Mean triglyceride concentrations and the prevalence of hypertriglyceridemia (50 percent) were significantly increased in patients with AIDS compared with control subjects (p less than 0.002 and p less than 0.005, respectively), whereas the mean triglyceride levels of HIV-positive subjects were intermediate. There were no differences in cholesterol levels among the three groups. Using total body potassium adjusted for height and age (KHT) as a measure of body cell mass, 16 of 32 patients with AIDS but none of the HIV-positive or control subjects had significant depletion of body cell mass. There was no direct relationship between triglyceride levels and KHT among AIDS or HIV-positive subjects. In patients with AIDS, mean triglyceride levels and the prevalence of hypertriglyceridemia were similar in the presence and absence of wasting.
Hypertriglyceridemia is a common finding in AIDS and is independent of the degree of wasting.
其他研究者提出细胞因子诱导的高甘油三酯血症与慢性感染中出现的恶病质之间存在关联。由于获得性免疫缺陷综合征(AIDS)患者常经历进行性组织消耗,我们决定检测AIDS患者的血脂水平和体细胞质量。
检测了32例获得性免疫缺陷综合征(AIDS)患者、8例抗人类免疫缺陷病毒(HIV)抗体阳性的无症状受试者以及17例未感染HIV抗体的异性恋和同性恋对照者的血脂水平和体细胞质量。
与对照者相比,AIDS患者的平均甘油三酯浓度和高甘油三酯血症患病率(50%)显著升高(分别为p<0.002和p<0.005),而HIV阳性受试者的平均甘油三酯水平处于中间值。三组之间的胆固醇水平无差异。以根据身高和年龄校正的全身钾含量(KHT)作为体细胞质量的指标,32例AIDS患者中有16例存在体细胞质量显著减少,而HIV阳性或对照者中均无此情况。在AIDS或HIV阳性受试者中,甘油三酯水平与KHT之间无直接关系。在AIDS患者中,无论是否存在消瘦,平均甘油三酯水平和高甘油三酯血症患病率相似。
高甘油三酯血症在AIDS中很常见,且与消瘦程度无关。
