Abstract
BACKGROUND: The mechanisms responsible for the onset of sensorimotor peripheral diabetic neuropathy (SMPN) remain largely unknown. To address this issue, we studied the relationship between traditional cardiovascular risk factors, parameters of metabolic control, and the presence of SMPN in patients with type 2 diabetes of relatively short duration. METHODS: Blood pressure, glycated hemoglobin, lipid profile, and the presence of micro- and macrovascular complications were assessed and monitored in 31 consecutive ambulatory patients with type 2 diabetes (age 60.7 +/- 7.5 years, mean +/- SD) within 10 years of diagnosis (mean diabetes duration 6.0 +/- 2.3 years). RESULTS: Clinical and neurophysiological features of SMPN were present in 10 patients (SMPN+, 32%). There were no significant differences in age, gender distribution, diabetes duration, body mass index, metabolic control, and serum cholesterol between SMPN- and SMPN+ patients. However, the prevalence of hypertension (i.e. blood pressure >/=140/90 mm Hg) was higher in SMPN+ patients (10/10 vs. 13/21, chi(2 =) 5.13, p = 0.025). Regression analysis showed that, after correcting for age, gender, duration of diabetes, glycated hemoglobin, and cholesterol, the presence of hypertension was independently associated with SMPN (R(2) = 0.17, p = 0.023). CONCLUSIONS: There is a strong association between hypertension and SMPN in type 2 diabetic patients with relatively short duration of disease. This relationship is independent of other risk factors.
