Acute asymmetrical neuritis associated with rapid ultrafiltration dialysis

Area of Science:

• Nephrology
• Neurology
• Vascular Medicine

Background:

• Chronic renal failure patients undergoing hemodialysis are susceptible to complications.
• Edema is a common complication requiring fluid management strategies like ultrafiltration.
• Neuropathies can occur in patients with chronic renal failure.

Purpose of the Study:

• To investigate the cause of acute neuropathies in hemodialysis patients experiencing ultrafiltration.
• To differentiate between uraemic polyneuritis and other neuropathy types.

Main Methods:

• Case study of three patients with chronic renal failure on hemodialysis.
• Observation of neuropathy development during ultrafiltration for edema treatment.
• Clinical and etiological analysis of the neuropathies.

Main Results:

• Three patients developed acute, asymmetrical sensory and motor neuropathies during ultrafiltration.
• The neuropathies presented as acute mononeuritis multiplex, distinct from typical uraemic polyneuritis.
• Evidence suggests an ischemic process due to vasoconstriction, not uremic toxins.

Conclusions:

• Ultrafiltration-induced vasoconstriction may cause acute neuropathies in hemodialysis patients.
• This ischemic neuropathy differs from uraemic polyneuritis.
• Careful monitoring during ultrafiltration is recommended for patients with chronic renal failure.
