KOMBINASI

PATOGENESE NEUROPATI DIABETIK

The etiology is uncertain.

4 hypothesis (not necessarily exclusive) :

1. Hyperglycemia-polyol-myoinositol hypothesis.

2. Microvascular hypothesis

3. Structural changes at the node of Ranvier.

4. Vasculitic neuropathy.

1. Hyperglycemia-polyol-myoinositol

hypothesis

Normal : glucose hexokinase glucose-6-phosphate Krebs cycle.

Hyperglycemia saturates hexokinase activity glucose shunted to polyol pathway production of sorbitol assoc w/ a decrease in intracelluler myoinositol defective Na/K ATPase activity defect axon transport slowing NCV

2. Microvascular hypothesis

DM : ** thickening of capillary basement membrane

** increase in the size and number of capillary endothelial cells

Microangiopathy increase number of closed capillaries in peripheral nerves progressive hypoxia secondary changes in axons and Schwann cells

3. Structural changes at the node of Ranvier

Na/K ATPase defiency increase intra-axonal Na and nodal axonal swelling detachment of myelin myelin retraction from the nodal area slowing of axonal conduction.

Exposure of paranodal K channels leakage of K impairment of axonal conduction.

Impairment of axonal transport gradual dying back of axons starting at the distal axons and progressing proximally.

4. Vasculitic neuropathy

Some cases of NIDDM and proximal diabetic have a inflammatory vasculopathy with perivascular collections of lymphocytes and axonal neuropathy
