Immunotherapy and Immune Responses

The authors studied the circulating fibronectin concentrations in the plasma of 24 patients with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex (ARC) and of 74 age- and sex-matched healthy blood donors. They adapted a commercially available turbidimetric immunoassay for use with a centrifugal analyzer. The assay showed within-run precision of 2.1%, 2.3%, 1.8%, and 1.1%, and an accuracy of 90%, 99%, 98%, and 98% at fibronectin concentrations of 126 mg/L, 200 mg/L, 293 mg/L, and 317 mg/L, respectively. Between-run precision was 5%, 3%, and 2% for 66 mg/L, 218 mg/L, and 283 mg/L concentrations, respectively. Plasma fibronectin values obtained from the healthy blood donors were in good agreement with those values reported by other investigators using various methods. No significant differences between the plasma fibronectin values of the patient population (mean ± 2 SD = 294 mg/L ±110 mg/L) and of the control group (mean ± 2 SD = 311 mg/L ± 130 mg/L) were noted. The authors conclude that the measurement of fibronectin concentrations in patients with AIDS or ARC does not contribute significantly to the diagnosis and therapeutic management of these patients.
