Abstract
Diabetic neuropathy is a serious complication of diabetes mellitus (DM). Its
commonest manifestation is diabetic peripheral neuropathy (DPN). Diabetic
neuropathy may also affect the autonomic nervous system, cardiac autonomic
neuropathy (CAN) being its most widely studied manifestation. Treatment of DPN
and CAN relies on glycaemic control and symptom alleviation, emphasizing the
need for improvement. To this purpose, the novel antidiabetic oral agents
sodium-glucose cotransporter-2 inhibitors (SGLT-2is) have been studied. Beyond
their favourable effects on metabolic control and cardiovascular and renal
outcomes, these agents appear to harbour some beneficial actions in DPN and CAN
as well. The underlying mechanisms are not entirely clear, but appear to involve
the 5' adenosine monophosphate-activated protein kinase (AMPK)-pathway.
So far, clinical experience has been limited. Significant improvement in
electrophysiological parameters and thermal perception has been observed among
subjects with type 2 diabetes mellitus (T2DM) in small studies. However,
contradictory findings have also been reported. The same ambiguous effect of
SGLT-2is has been observed in CAN. Thus, future large studies are required to
delineate the utility of SGLT-2is in DPN and/or CAN.
