Microvascular and neuropathic complications of diabetes mellitus can be
significantly decreased by long-term, near-normoglycemic regulation in
patients with insulin-dependent diabetes mellitus. Prevention or delay of
onset of hyperglycemia in non-insulin-dependent diabetes mellitus (NIDDM)
patients should reduce morbidity and mortality from these complications.
NIDDM can be nearly normoglycemic when diagnosed by screening before its
symptomatic stage or when clinically hyperglycemic NIDDM goes into
remission. One potential strategy to delay the onset of hyperglycemia in
individuals at high risk is chronic low-dose sulfonylurea therapy. Thirty
black NIDDM subjects who recently had developed near-normoglycemia were
followed with no treatment or were randomly assigned to a 3-year,
double-blind glipizide or placebo treatment. Baseline and follow-up
parameters included fasting plasma glucose (FPG), HbA1c, plasma insulin,
and glucose responses to an oral glucose tolerance test and insulin action,
as determined by the euglycemic insulin clamp. Baseline FPG and HbA1c for
all three groups were 107 mg/dl and 4.7%, respectively. Relapse to
hyperglycemia was defined as an FPG level > or = 140 mg/dl on several
consecutive visits or an FPG level > or = 140 mg/dl and symptoms of
hyperglycemia. During the course of the treatment and follow-up,
hyperglycemia occurred in 6 of 10 subjects in the no treatment group, 6 of
10 in the placebo group, and 2 of 10 in the glipizide treatment group.
Prolongation of near-normoglycemia was significantly (P < 0.05)
increased by low-dose (2.5 mg/day) glipizide compared with placebo
treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
