Diabetic peripheral neuropathy (DPN) is one of the most commonly occurring
major complications of diabetes. The disease may manifest in several clinic
al patterns: most frequently as distal symmetrical sensory polyneuropathy.
Guidelines are available for the diagnosis of DPN by the primary care physi
cian. These recommend that a review of diabetic patients, including a quest
ionnaire and inspection and neurological examination of the feet, is undert
aken annually. Techniques used for studying the disease process in clinical
trials may include nerve conduction and quantitative sensory function test
s, autonomic nervous system testing, post-ganglionic sudomotor function and
skin biopsy. Current therapies for managing DPN are strict glycaemic contr
ol, palliative treatments and foot ulcer prevention. Future treatments aim
to beneficially affect the underlying disease pathology and putative agents
are currently being investigated.
