Reduced myocardial 123I-metaiodobenzylguanidine uptake in newly diagnosed IDDM patients

123I-labeled metaiodobenzylguanidine (123I-MIBG) scintigraphy is a novel
technique for the assessment of cardiac sympathetic dysinnervation. To
evaluate defects of the cardiac autonomic nervous system at the onset of
IDDM, this technique together with conventional electrocardiogram
(ECG)-based cardiac reflex tests and measurement of the QT interval was
applied to 22 newly diagnosed metabolically stabilized IDDM patients
without myocardial perfusion abnormalities (99mTc-labeled
methoxyisobutylisonitrile scintigraphy) and 9 matched control subjects.
Seventeen diabetic patients (77%), but none of the control subjects, were
observed to have a reduced global myocardial uptake of 123I-MIBG. In
contrast, only two diabetic patients (9%) demonstrated an ECG-based cardiac
autonomic neuropathy (two or more of five age-related cardiac reflex tests
abnormal) (P < 0.001). In newly diagnosed IDDM patients, the uptake of
123I-MIBG was reduced more in the posterior myocardial region compared with
the lateral and apical region (P < 0.01, P = 0.03). The septal
myocardial region exhibited a smaller uptake than the lateral myocardial
region (P = 0.02). The maximum/minimum 30:15 ratio correlated with the
global, anterior, lateral, and septal myocardial uptake of 123I-MIBG (P
< 0.05, P < 0.05, P < 0.01, P < 0.05). A correlation between
global and regional myocardial 123I-MIBG uptake and HbA1c or QT interval
was not observed. Newly diagnosed metabolically stabilized IDDM patients
without myocardial perfusion defects show evidence of cardiac sympathetic
dysinnervation, as indicated by a reduction of 123I-MIBG uptake, at a
significant higher proportion than ECG-based cardiac autonomic neuropathy.
Furthermore, they present with regional differences of myocardial 123I-MIBG
uptake.
