Serial changes in glycosylated blood proteins and direct measures of glycemia were studied in 100 subjects with insulin-dependent diabetes mellitus (IDDM) over a 6-wk period while attempts were made to improve glycemic control. All measures of glycemic control improved significantly (P less than .001). Mean +/- SE glycosylated hemoglobin (HbA1) fell from 9.1 +/- 0.2 to 8.0 +/- 0.1%, glycosylated serum albumin (GSA) from 9.8 +/- 0.4 to 7.3 +/- 0.3%, and fructosamine from 3.92 +/- 0.08 to 3.42 +/- 0.07 mM. Fasting blood glucose levels fell from 11.1 +/- 0.6 to 8.1 +/- 0.7 mM mean blood glucose levels from 12.5 +/- 0.3 to 8.8 +/- 0.03 mM, and the M value from 118 +/- 7 to 40 +/- 3 U. Mean percentage changes in direct measures of glycemia (32-66%) and GSA (29%) were greater than for fructosamine (11%) or HbA, (12%) levels (P less than .001). Furthermore, the correlation between the change in GSA and changes in direct measures of glycemia over the initial 2-wk period was significantly different from the corresponding correlations between direct measures of glycemia and fructosamine over this period (P less than .05-.01). Changes in GSA also correlated more closely than HbA1 or fructosamine did with direct measures of glycemia after 4 and 6 wk. The Spearman rank-correlation coefficient (rs) of absolute changes in GSA, fructosamine, and HbA1 after 2-6 wk ranged from 0.27 to 0.57, confirming that the three measures responded differently to changing glycemic control.(ABSTRACT TRUNCATED AT 250 WORDS)

UI	MeSH Term	Description	Entries
D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D003922	Diabetes Mellitus, Type 1	A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

D006031	Glycosylation	The synthetic chemistry reaction or enzymatic reaction of adding carbohydrate or glycosyl groups. GLYCOSYLTRANSFERASES carry out the enzymatic glycosylation reactions. The spontaneous, non-enzymatic attachment of reducing sugars to free amino groups in proteins, lipids, or nucleic acids is called GLYCATION (see MAILLARD REACTION).
