title: Dyslipidemia as a contributory factor in etiopathogenesis of diabetic neuropathy.
abstract: OBJECTIVE
  The pathogenesis of neuropathy in type 2 diabetes mellitus is multifactorial.Dyslipidemia may contribute to the development of diabetic neuropathy. This study aimed to assess the atherogenic lipid indices in type 2 diabetic patients with neuropathy.
  
  
  METHODS
  Fifty-one patients with type 2 diabetes mellitus and 31 healthy subjects were studied in the Unit of Neurophysiology at the University Hospital of Medical College, Al-Nahrin University in Baghdad, Iraq, from January 2002 to January 2003. Neuropathy total symptom score (NTSS), neuropathy impairment score in the lower leg (NIS-LL), and electrophysiological study of sensory (ulnar and sural) and motor (ulnar and common peroneal) nerves were used to assess nerve function. Fasting venous blood was obtained from each participant for determination of lipid profile and atherogenic lipid ratios.
  
  
  RESULTS
  The frequency of high blood pressure was significantly higher in neuropathic patients. The electrophysiology study revealed significant decrease in conduction velocity of ulnar (sensory and motor components), sural, and common peroneal nerves. The minimum F-wave latency of motor nerve was significantly prolonged. Among the lipid fractions, only high-density lipoprotein-cholesterol was significantly reduced by 14% of healthy participant's value. Atherogenic lipid ratios were significantly higher in diabetic patients than corresponding healthy ratios.
  
  
  CONCLUSIONS
  Metabolic lipid disturbances in terms of atherogenicity co-existwith neuropathy in type 2 diabetes mellitus, irrespective of duration of disease.
