    ABSTRACT: To determine the prevalence of diabetic peripheral neuropathy (DPN) and risk factors associated with DPN in type 2 diabetic patients. 435 diabetic patients were evaluated on complete foot examination. Body mass measurements, resting blood pressure, fasting blood measures, urinary albumin-to-creatinine ratio (ACR) and the digitally stored fundus images were investigated. (1) The prevalence of DPN was 61.8% among the Chinese patients diagnosed with type 2 diabetes aged over 30 in the Shanghai downtown, 59.1% with vibration perception threshold > or =25 V and 13.8% with inability to feel the monofilament. (2) DPN was significantly associated with age (beta: 0.068, S.E.: 0.013, OR: 1.070, CI: 1.043-1.098, P<0.001) and HbA1c (beta: 0.224, S.E.: 0.081, OR: 1.251, CI: 1.067-1.466, P=0.006) by a logistic regression analysis. (3) The percentage of diabetic retinopathy (DR) in the DPN group (26.5%) was significantly higher than that in the non-DPN group (15.2%). (4) The percentage of macroalbuminuria in the DPN group (9.0%) was significantly higher than that in the non-DPN group (1.8%). The prevalence of DPN observed in the Chinese patients diagnosed with type 2 diabetes aged over 30 in the Shanghai downtown reached up to 61.8% though the observations in our study might be representative of the diabetic patients of the Shanghai downtown.

    ABSTRACT: This study aimed to evaluate the prevalence of chronic kidney disease (CKD) and the risk factors associated with CKD among Chinese patients diagnosed with type 2 diabetes aged over 30 in downtown Shanghai and to assess the relationship between CKD and diabetic retinopathy (DR). We investigated 1039 Chinese patients diagnosed with type 2 diabetes aged over 30 by randomized cluster sampling in downtown Shanghai, and 1009 patients in this study were analyzed based on data integrity. Body measurements including height, weight, waist circumference and hip circumference, resting blood pressure, fasting blood measures, and urinary albumin-to-creatinine ratio (ACR), as well as the digitally stored fundus images, were investigated. Glomerular filtration rate (GFR) was estimated using the Cockcroft-Gault equation. The prevalence of CKD was calculated, and the risk factors associated with CKD were evaluated using stepwise logistic regression. The relationship between CKD and DR was evaluated using Spearman correlation and the chi-square test. The following were the results found in this study: (a) The prevalence rate of CKD (Stages 1-5) was 63.9% in Chinese patients diagnosed with type 2 diabetes, 8.8% in those with CKD Stage 1, 22.3% in those with CKD Stage 2, and 32.8% in those with CKD Stages 3-5 (GFR<60 ml/min/1.73 m(2)). The prevalence of CKD increased with age. (b) CKD patients were older and had higher duration of diabetes, systolic blood pressure, urea nitrogen, uric acid, creatinine, and ACR of the first urine than those without CKD. (c) Male patients had a higher percentage of CKD Stages 3-5, and female patients had a higher percentage of CKD Stages 1-2. (d) CKD was significantly associated with duration of diabetes, older age, systolic blood pressure, and serum urea nitrogen based on logistic regression analysis. (e) Of the patients without CKD, 15.6% had DR, and of those with CKD, 27.6% had DR. The decrease in GFR was significantly correlated with DR after controlling for sex, age, and albuminuria staging. The high prevalence of CKD observed in Chinese patients diagnosed with type 2 diabetes aged over 30 in downtown Shanghai was similar to that in Western patients, and the cause of CKD is likely to be any of the following: type 2 diabetes, IgA nephropathy, hypertension, or any combination of these. The screening program for GFR in type 2 diabetic patients should be performed even on those with normoalbuminuria. The decrease in GFR might predict the occurrence of DR among patients diagnosed with type 2 diabetes.

    ABSTRACT: The objective of the study was to determine the most accurate metabolic syndrome (MS) definition among the definitions proposed by the International Diabetes Federation (IDF), the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III [ATPIII]), and the World Health Organization (WHO) and to evaluate the cutoff point of waist circumference using the IDF definition for optimally defining MS in the Chinese population. One thousand thirty-nine Chinese patients older than 30 years and diagnosed with type 2 diabetes mellitus were investigated by randomized cluster sampling in the Shanghai downtown, and 1008 patients were analyzed in this study. Body mass measurements, resting blood pressure, fasting blood measures, and carotid atherosclerotic measurements including common carotid artery intima-media thickness (IMT) and carotid plaque were investigated. The IDF definition was compared with the other 2 definitions, and the carotid atherosclerosis was evaluated among the patients according to these definitions. (1) The MS prevalence was 50.0%, 55.7%, and 70.0% under the IDF, ATPIII, and WHO definitions, respectively. (2) The percentage of all the participants categorized as either having or not having the MS was 69.9% (under the IDF and ATPIII definitions) and 70.2% (under the IDF and WHO definitions). (3) Common carotid artery IMT of patients with MS determined by the IDF definition was thicker than those determined by the WHO and ATPIII definitions, and the percentage of carotid plaque of patients with MS determined by the IDF definition was greater than those determined by the WHO and ATPIII definitions. (4) When the cutoff point of waist circumference in men determined by the IDF definition was modified from 90 to 85 cm, common carotid artery IMT of the emerging male patients with MS was thicker than that of the male patients with MS determined by the original IDF definition. In conclusion, the prevalence of MS was 50.0%, 55.7%, and 70.0% under the IDF, ATPIII, and WHO definitions, respectively. The preferable IDF definition served as a better predictor of cardiovascular disease risk in the Chinese patients diagnosed with type 2 diabetes mellitus compared with the ATPIII and WHO definitions. The modified cutoff point of waist circumference in men under the IDF definition specific for the Chinese population (from 90 to 85 cm) might be more suitable for predicting atherosclerosis.
