Abstract:
Objective: To determine prevalence and factors associated with neuropathic pain symptoms in a multiethniccohort of Malaysian adult diabetic patients. Methods: This was aprospective cross-sectionalobservational study of hospital-based diabetic outpatients in Malaysia. Subjects were interviewedfor their demographic data and medical history. The painDETECT questionnaire was used to screenfor neuropathic pain symptoms and pain intensity was assessed using the numeric pain rating scale(NPRS). Neuropathy symptoms and signs were assessed using the Neuropathy Symptom Score(NSS) and Neuropathy Disability Score (NDS). Results:Of 242 patients,140 (58%) were women,with a mean age of 61 + 11.4 years (range 21 to 81). Ninety nine(40.9%) were Malay, 64 (26.4%)Chinese, 76 (31.4%) Indian and three (1.2%) were Eurasian. Mean duration of diabetes was 15.9+ 9.8years (range 1 to 53) and 232 (95.9%) patients had Type II diabetes. Peripheral neuropathy,based onNSS and NDS criteria, was found in 83 (34.3%). Thirteen (5.4%) patients were found to likely haveneuropathic pain symptoms and this was independently associated with peripheral neuropathy ((OR)= 3.40, 95% confidence interval (CI): 1.04, 11.14) and Indian ethnicity (OR = 5.44, 95% CI: 1.50,19.57)). Patients with neuropathic pain had higher average pain intensity scores.Conclusions: The prevalence of neuropathic pain symptoms in a Malaysian DM patient cohort waslow and was associated with the severity of neuropathy symptoms and Indian ethnicity. The causesfor ethnic differences are unknown and could be due socio-cultural or physiological differences inneuropathic pain perception.
