The natural history of Human Immunodeficiency Virus (HIV) infection is incompletely understood. Factors other than HIV infection alone may be required for the development of the profound immunosuppression that characterizes advanced HIV disease. Nutritional status plays an important role in maintaining normal immunity and thus may be one of these factors. The plasma concentrations of C-reactive protein, transferrin, selected trace elements (Mg, Zn, Fe, Cu, Cd, Se and Cr,), total protein and albumin were determined in 25 asymptomatic HIV-infected Nigerian subjects and 30 age matched HIV-seronegative controls using single radial immunodiffusion and spectrophotometric methods. The mean values of Cu (73.2 + 23.9 microg/dl), Mg (9.83 + 5.5 mg/dl), Fe (126 + 21 microg/L), Cd (24.6 + 7.2 microg/L), Se (22.0 + 12.2 microg/dl) and Cr (19.0 + 5.2 microg/L) were low in asymptomatic HIV-positive subjects when compared with the controls (Cu = 119.3 + 30.8 microg/dl; Mg = 14.5 + 4.6 mg/L; Fe = 155 + 8.8 microg/ dl; Cd = 33. 1 + 8.3 microg/L; Se = 30.9 + 8.3 microg/dl; Cr = 32.1 + 7.8 microg/ L). The level of Zn was similar in asymptomatic HIV-positive subjects (5.1 + 1.9 mg/dl) and the controls (4.6 + 1.7mg/dl). The value of albumin in asymptomatic HIV-positive subjects (3.43 + 0.7 g/dl) was significantly low when compared with the controls (4.04 + 0.52 g/dl). Significant correlation existed between albumin and Mg in asymptomatic HIV subjects (r = + 0.758, p < 0.001). The mean value of C-reactive protein was significantly higher in HIV-infected subjects compared with the controls while the level of transferrin in HIV-infected subjects (92.86 + 26.3 mg/dl) did not show any significant difference when compared with the controls (84.36 + 16.9 mg/dl). This study revealed the deficiencies of trace elements in asymptomatic HIV infection and therefore suggests dietary supplementation of these trace elements in the infected subjects.
人类免疫缺陷病毒(HIV)感染的自然史尚未完全明了。晚期HIV疾病所特有的严重免疫抑制的发展可能需要HIV感染以外的其他因素。营养状况在维持正常免疫方面起着重要作用,因此可能是这些因素之一。采用单向免疫扩散法和分光光度法,对25名无症状HIV感染的尼日利亚受试者和30名年龄匹配的HIV血清阴性对照者的血浆C反应蛋白、转铁蛋白、选定的微量元素(镁、锌、铁、铜、镉、硒和铬)、总蛋白和白蛋白浓度进行了测定。与对照组相比,无症状HIV阳性受试者的铜(73.2 + 23.9微克/分升)、镁(9.83 + 5.5毫克/分升)、铁(126 + 21微克/升)、镉(24.6 + 7.2微克/升)、硒(22.0 + 12.2微克/分升)和铬(19.0 + 5.2微克/升)的平均值较低(铜 = 119.3 + 30.8微克/分升;镁 = 14.5 + 4.6毫克/升;铁 = 155 + 8.8微克/分升;镉 = 33.1 + 8.3微克/升;硒 = 30.9 + 8.3微克/分升;铬 = 32.1 + 7.8微克/升)。无症状HIV阳性受试者的锌水平(5.1 + 1.9毫克/分升)与对照组(4.6 + 1.7毫克/分升)相似。与对照组(4.04 + 0.52克/分升)相比,无症状HIV阳性受试者的白蛋白值(3.43 + 0.7克/分升)显著较低。无症状HIV受试者中白蛋白与镁之间存在显著相关性(r = + 0.758,p < 0.001)。与对照组相比,HIV感染受试者的C反应蛋白平均值显著更高,而HIV感染受试者的转铁蛋白水平(92.86 + 26.3毫克/分升)与对照组(84.36 + 16.9毫克/分升)相比未显示出任何显著差异。这项研究揭示了无症状HIV感染中微量元素的缺乏,因此建议对感染受试者进行这些微量元素的膳食补充。
