INTRODUCTION
• Is the presence of symptoms and signs of nervous dysfunction in people with diabetes after exclusion of other causes
• It’s the commonest complication of long standing diabetes
• Up to 50% of diabetics will come down with one form of neuropathy or the other.
![Page 4: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/4.jpg)
Epidemiology
• Up to 70% of people with diabetes will experience neuropathy
• Some form of neuropathy may already be present at time of making a diagnosis of type 2 DM
• 95.7% 0f patients with DFU had neuropathy(Ikem et al 2002
• More than 60% of nontraumatic lower-limb amputations in the United States occur among people with diabetes following neuropathy
![Page 5: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/5.jpg)
Classification of Diabetic Neuropathy
• Somatic polyneuropathy1) Symmetrical sensory neuropathy(distal)2) Asymmetrical motor neuropathy(proximal),
including amyotrophy
• Mononeuropathy and mononeuritis multiplex
• Autonomic neuropathy
![Page 6: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/6.jpg)

Risk Factors• Poor glycaemic control• Advanced age• Long duration of diabetes• Hypertension• dyslipidaemia• HLA DR3/DR4 phenotype• Smoking• Heavy alcohol intake• Height i.e tall stature
![Page 7: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/7.jpg)
Pathogenesis
• Hyperglycaemia is directly toxic to cells;altering cell growth,gene and protein expression,hence increasing ECM and TGF beta production
• Formation of AGES(advanced glycosylation end products); may disrupt neuronal integrity by stimulation of pro-inflammatory cytokines and complements
![Page 8: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/8.jpg)
Pathogenesis ctd
• Polyol pathway; accumulation of sorbitol and fructose in schwann cells lead to decreased nerve myoinositol,reduced Na-k ATPase activity, impaired axonal transport,abnormal AP propagation and breakdown of nerve structure
• DAG/PKc pathway; pkc alters gene transcription for fibronectin,type 4 collagen,contractile proteins,ECM in the neurones
![Page 9: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/9.jpg)
Pathogenesis
• Oxidative stress; increased free radicals and reactive oxygen species produced in DM cause direct damage to blood vessels(vasa nervorum) leading to nerve ischaemia and hypoxia
• This may be the major pathogenetic mechanism in mononeuropathies
![Page 10: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/10.jpg)
Other mechanisms
• Immune mechanisms• Decreased neurotrophic growth factors• Decreased essential fatty acids• Depletion of ATP by polyADP ribosylation
![Page 11: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/11.jpg)
Symmetrical sensory polyneuropathy
• Most common form of diabetic neuropathy • Affects distal lower extremities and hands
(“stocking-glove” sensory loss) • Symptoms
– Feeling of numbness or deadness– Tingling, prickling,aching, burning sensations– Paresthesia(hyper/hypoasthesia,)– Loss of vibratory sensation– Loss of balance in the dark– Loss of pain sensation

Treatment
• Tight and stable glucose control slows the progression of neuropathy
• Drugs used in peripheral neuropathy include the antidepressants(amitryptiline, desipramine, imipramine, nortriptyline) SSRIs e.g duloxetine anticonvulsants like pregabalin, gabapentin, carbamazepine, lamotrigine
• However response haven’t been satisfactory and patients need lots of psychological support.

Counselling for patients with neuropathic foot
• Do check your feet each day for blisters, cuts, scratches, reddened areas. Use a mirror or ask someone else to help look at the soles.
• Do wash your feet each day. Dry them carefully especially between the toes.
• Do avoid extremely hot or cold water. Test them with your hand or elbow before use.
• Do apply a very thin coat of lubricating oil or cream on the skin after bathing if your skin is dry but not between the toes
![Page 42: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/42.jpg)
Counseling ctd
• Do ask about therapeutic shoes if you have a foot deformity, such as bunions or claw toes or previous ulcer
• Do see your care provider for regular foot examination.
• Always protect your feet. Wear shoes both in and outside the house to avoid injury
![Page 43: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/43.jpg)
Counseling ctd• Don’t walk barefoot.• Don’t walk on hot surfaces, such as sandy beaches or the
cement, roads etc.• Don’t put hot water bottles, electric blanket or heating pad on
your feet.• Don't cut corns, calluses or use chemical agents, corn plasters,
strong antiseptics on your feet.• Don’t soak your feet unless professionally advised.• Don’t wear shoes without stockings.• Don’t wear sandals with thongs between the toes.• Avoid pointy-toe shoes, high heels, stilettos, strapless and
backless shoes• Don’t smoke• Don’t put jewellery on your feet
![Page 44: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/44.jpg)
Prognosis
• Repetitive trauma to a neuropathic area may cause ulceration and infection and amputations
• Neuropathic foot ulceration and amputation is the commonest cause of admission of DM patients
• Mortality is mainly from cardiac autonomic neuropathy.
• Such patients are at risk of sudden death
![Page 45: Diabetic Neuropathy EMEGOAKOR NONSO. Outline Introduction Epidemiology Classification Risk factors Pathogenesis Clinical presentation Physical examination.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b48d7550346dd1a8b5a9c/html5/thumbnails/45.jpg)
conclusion
• DM neuropathy is the commonest chronic complication in diabetics
• Poor glycaemic control and prolonged duration of DM are the greatest risk factors
• Major cause of non traumatic lower limb amputations as well as sudden deaths
• Strict blood glucose control is advised to prevent or delay it’s progression
