CLINICAL STUDIES / ETUDE CLINIQUES ETUDE COMPAREE DES ASPECTS CLINIQUES ET ELECTROMYOGRAPHIQUES DES POLYRADICULONEUROPATHIES INFLAMMATOIRES DEMYELINISANTES CHRONIQUES IDIOPATHIQUES ENTRE LES DIABETIQUES ET LES NON DIABETIQUES COMPARATIVE STUDY OF CLINICAL AND ELECTROMYOGRAPHIC ASPECTS OF CHRONIC INFLAMMATORY DEMYELINATING POLYRADICULONEUROPATHY IDIOPATHIC BETWEEN DIABETICS AND NON DIABETICS

Background The Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) is common in diabetic patients 18.9%. But a few surveys have compared the IPDC between diabetic and nondiabetic. Objective To study the IPDC between diabetic and nondiabetic. Methodology This descriptive survey examined 47 patients including 21 diabetics and 26 non-diabetics with CIDP admitted to the neurophysiology laboratory of the CHU of Limoges from January 2006 to June 2008. The diagnosis of CIDP was focused on INCAT electrophysiological criteria and distal latency greater than 9 ms. Results The clinical comparison reveals that there was no difference between the two populations as regard age, gender, presence of physical deficit disturbances, objective sensory troubles (p> 0, 05). However, the diabetic patients had more pain than non-diabetics (p = 0.006). At the electrophysiology level, there are more blocks conduction in non-diabetics (88.5%) than in diabetics (47.6%) p =0.002. At the median nerve, diabetics had less elongation of distal latency (27.8%) than non-diabetics (47.4%) p = 0.01. A comparative study of the results shows that subjects without diabetes have a higher F wave lying on the median (41.2 ms), the ulnar nerve (40.6ms) and SPE (65.8 ms) than diabetics. The reduction of nerve conduction velocity is higher in the non-diabetic on the ulnar nerve (34.3 m / sec). Conclusion These results show that diabetics may have CIDP but with different physiological and clinical aspects of nondiabetics.
