• Polyneuropathy is an important complication in
diabetic patients.
• Polyneuropathy may ocur with asymptomatic high
HbA1c levels.
• It is important to perform EMG in the early period with
asymptomatic HbA1c elevation.
Introduction: It is aimed to investigate the relationship between the
asymptomatic elevation of HbA1c and occurrence of polyneuropathy
by way of comparison to normoglycemic condition.
Methods: The study includes 30 female patients diagnosed with
subclinical elevation of HbA1c and 30 normoglycemic healthy female
patients who applied to our hospital polyclinics with symptoms other
than neuropathy between January-March 2017. Nerve conduction
examination is done in these patients, parameters of both groups are
compared.
Results: In regard to amplitude distribution; when compared to control
group, tibial motor and ulnar sensory nerve amplitude is lower than the
control group (p<0.05). In peroneal, median and ulnar motor nerves,
distal latency values are extended compared to control group (p<0.05).
Sural, median and ulnar sensory nerve latency is extended compared to
control group. In terms of transmission rate distribution; in sural, median
and ulnar sensory nerve, transmission speed is lower compared to the
control group (p<0.05)
Conclusions: In asymptomatic cases with subclinical elevation of
HbA1c, peripheral nervous system involvement is monitored, and early
glycemic control should be provided in order to prevent development of
neuropathy in patients.
