Incidence and management of severe hypoglycemia in 434 adults with insulin-dependent diabetes mellitus

The risk of severe hypoglycemia associated with the particular therapeutic
approach of two University hospitals was assessed in 96% of all patients
with insulin-dependent diabetes mellitus (IDDM) who had been admitted
during a period of almost 3 yr to the diabetic wards of two hospitals and
who participated in a structured teaching and treatment program. During a
mean follow-up period of 18 mo, 10% of the conventionally treated patients
(N = 384; age 30 +/- 13 yr; duration of diabetes 12 +/- 9 yr) and 9% of the
CSII-treated patients (N = 50, age 28 +/- 7 yr, duration of diabetes 13 +/-
7 yr, total follow-up period 1093 patient-mo) experienced at least one
severe hypoglycemic episode per year, and a total of 123 severe
hypoglycemic episodes occurred. In a subgroup of 169 conventionally treated
patients, mean glycosylated hemoglobin values decreased from 10.5 +/- 1.9%
before participation in the program to 9.2 +/- 2.0% (P less than 0.001) 18
+/- 4 mo thereafter. For the CSII-treated patients, glycosylated hemoglobin
values were 9.7 +/- 1.9% before initiation of pump therapy and remained at
the upper normal range from 3 mo thereafter throughout the study. There was
no relationship between glycosylated hemoglobin levels and the occurrence
of severe hypoglycemic episodes. Fifty-three severe hypoglycemic episodes
were treated with glucagon injections by the patients' relatives (all but
one effectively), 30 were managed by assisting physicians, and 44 led to
hospitalization. Thus, successful attempts to improve glycosylated
hemoglobin values in an unselected group of patients with IDDM were not
associated with an unduly high risk of severe hypoglycemia when compared
with the scarce data from the literature.
