Paper 2
Question 1
• The diabetes complication and control trial (dcct)
showed that strict glycaemic control ( hba1c
%<7%) did which of the following
A) prevented the progression of severe retinopathy
B) prevented the onset of macrovascular disease
C) reduced the prevalence of hypoglycaemic
episodes
D) reduced the progression of microalbuminuria
E) prolonged life in type 2 diabetes
• In the DCCT, intensive intervention resulted in a 63%
reduction in retinopathy progression, a 47% decrease in
development of severe non-proliferative diabetic
retinopathy, a 39% and 54% reduction in
microalbuminuria and macroalbuminuria, respectively,
and a 60% reduction in clinical neuropathy at 5 years.
• Aggressive early intervention before the manifestation of
complications yielded the best results. In both intensive
and conventional treatment groups in the DCCT, there
was approximately a 40% reduction in risk of
progression of retinopathy for each 10% proportional
reduction in hemoglobin A1c (HbA1c). At the conclusion
of the DCCT, participants learned about the results, and
all were encouraged and helped to adopt intensive
treatment.
