Recently, new serum glycated protein assays (ie, serum fructosamine) have been developed. Fructosamine assays objectively monitor short‐term glycemic control and, when used in conjunction with HgA1C, enhance the clinical information obtained and greatly aid in the clinical management of diabetes. Because they rely on glycation of serum proteins, the clinical utility of these assays in the elderly may be altered secondary to the hypoproteinemia that often is seen in these states. Therefore, we investigated the role of glycated serum proteins (ie, fructosamine level) in monitoring elderly diabetics over a 4‐month period of observation. We found that the fasting blood glucose over the 4‐month period correlated well with the serum fructosamine activity (r = 0.79, P < .001) and HgA1C (r = 0.78, P < .001). In addition, we found that the mean daily glucose, as determined by outpatient monitoring, correlated well to both the fructosamine activity (r = 0.66, P < .001) and HgA1C (r = 0.74, P < .001). We found no effect on the measurement of the fructosamine assay by the level of albumin seen in these patients. Our study suggests that serum fructosamine and HgA1C are equally effective in monitoring the elderly patient, as has been established in the younger diabetic, and no correction need be made in the fructosamine assay to compensate for variable serum protein levels seen clinically in the elderly. |
