Serum histidine-rich glycoprotein levels are decreased in acquired immune deficiency syndrome and by steroid therapy.
Using radial immunodiffusion serum histidine-rich glycoprotein (HRG) levels were measured in acquired immune deficiency syndrome (AIDS) patients, in end-stage renal disease (ESRD) patients after renal transplantation and immunosuppressive steroid therapy, and in asthma and chronic obstructive pulmonary disease (COPD) patients treated with steroids. Compared with controls (12.5 +/- 3.0 mg/dl), HRG levels were significantly decreased in patients with AIDS (5.7 +/- 1.8 mg/dl, P less than 0.005): in patients with ESRD after renal transplantation with steroid therapy (4.4 +/- 1.1 mg/dl, P less than 0.005); and in asthmatic and COPD patients receiving steroids in acute (7.6 +/- 2.9 mg/dl, P less than 0.005) or chronic (7.4 +/- 3.0 mg/dl, P less than 0.025) high-dose regimens. In contrast, levels of hemopexin, another serum glycoprotein synthesized by the liver, were not lowered in these patients. These results show that serum HRG levels are selectively decreased in AIDS and in patients treated with immunosuppressive steroids.[1]References
