Background: This study compared the risk of developing new-onset diabetes between hemodialysis (HD) and peritoneal dialysis (PD) patients. We further investigated the effectiveness of icodextrin in reducing the risk of new-onset diabetes in PD patients. Methods: From the Taiwan health insurance database, 36 879 incident HD patients and 6382 incident PD patients from 2000 to 2010 were identified as study cohorts. We further selected an additional HD cohort matched by propensity scores (PSs) of PD patients. Incidence rates and hazard ratios (HRs) of new-onset diabetes were assessed among cohorts and between icodextrin users and nonusers by the end of 2011. Results: For the unmatched cohorts, the incidence of new-onset diabetes was higher in PD patients than in HD patients (9.16 versus 8.18 per 1000 person-years), with an adjusted HR of 1.51 (95% CI 1.30-1.75) for PD patients. For the PS-matched cohorts, the corresponding incidence rates were 9.43 and 5.90 per 1000 person-years, respectively, with an adjusted HR of 1.61 (95% CI 1.32-1.97). Among PD patients, the incidence was lower in icodextrin users than in nonusers (6.22 versus 12.1 per 1000 person-years), with an adjusted HR of 0.66 (95% CI 0.50-0.88) for users. Conclusions: Our study suggests that PD patients are at a higher risk of developing new-onset diabetes than HD patients. Icodextrin is recommended for PD patients to reduce the risk of new-onset diabetes. [ABSTRACT FROM AUTHOR]

Objective. Diabetic retinopathy (DR), the most common microvascular complication of diabetes mellitus (DM), can cause severe visual impairment and blindness. To prevent the development of DR, identifying the associated riskfactors forpatient classification is critical. We conducted a cross-sectional study to determine whether body constitution (BC) is an independent predictor of DR. Method. 673 type 2 DM (T2DM) patients were recruited from a medical center, all received DR examination and body constitution questionnaire to assess BC. Other risk factors for DR were also recorded, including life style, history of diabetes, and blood pressure, etc. Multiple logistic regression analysis was conducted to calculate the odds ratios (ORs) for DR. Results. The prevalence of DR was significantly lower in Yang deficiency patients compared with non-Yang deficiency patients (24.69% versus 38.18% P = 0.02). After adjusting for other risk factors, we observed that patients exhibiting Yang deficiency BC were less likely to present with DR (OR = 0.531; 95% confidence interval = 0.312-0.903, P = 0.018). Conclusion. In addition to traditional risk factors, Yang deficiency BC might be an independent predictor of DR among T2DM patients and the results can be used as evidence for traditional Chinese medicine patient classification.

Aim. To evaluate how health-related quality of life (HRQOL) and traditional Chinese medicine (TCM) constitutions of Yin-Xu, Yang-Xu, and Stasis are related in type 2 diabetes patients. Method. Seven hundred and five subjects were recruited in 2010 for this study from a Diabetes Shared Care Network in Taiwan. Generic and disease-specific HRQOL were assessed by the short form 36 (SF-36) and the diabetes impact measurement scale (DIMS). Constitutions of Yin-Xu, Yang-Xu, and Stasis were then assessed by the body constitution questionnaire (BCQ), a questionnaire consisting of 44 items that evaluate the physiological state based on subjective symptoms and signs. Results. Estimated effects of the Ying-Xu and Stasis on all scales of the SF-36 were significantly negative, while estimated effects of the Yang-Xu on all scales (except for SF, RE, MH, and MCS) were significantly negative. For DIMS, the estimated effects of the Ying-Xu and Stasis on all scales were significantly negative except for Stasis on well-being, while Yang-Xu has a significantly negative effect only on symptoms. Conclusions. This study demonstrates that TCM constitutions of Yin-Xu, Yang-Xu, and Stasis are closely related to a reduction in HRQOL. These findings support the need for further research into the impact of intervention for TCM constitutions on HRQOL in patients with type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background: The worldwide increasing trend of chronic kidney disease (CKD) is of great concern and the role of heart disease deserves longitudinal studies. This study investigated the risk of developing CKD among patients with heart diseases. Methods: From universal insurance claims data in Taiwan, we retrospectively identified a cohort of 26005 patients with newly diagnosed heart diseases and 52010 people without such disease from the 2000-2001 claims. We observed prospectively both cohorts until the end of 2007 to measure CKD incidence rates in both cohorts and hazard ratios (HR) of CKD. Results: The incidence of CKD in the cohort with heart disease was 4.1 times greater than that in the comparison cohort (39.5 vs. 9.65 per 10,000 person-years). However, the HR changed into 2.37 (95% confidence interval (CI) = 2.05 - 2.74) in the multivariate Cox proportional hazard model after controlling for sociodemographic characteristics and comorbidity. Compared with individuals aged < 40 years, the HRs for CKD ranged from 2.70 to 4.99 in older age groups. Significant estimated relative risks of CKD observed in our patients were also independently associated with hypertension (HR = 2.26, 95% CI = 1.94 - 2.63) and diabetes mellitus (HR = 2.44, 95% CI = 2.13 - 2.80), but not with hyperlipidemia (HR =1.13, 95% CI = 0.99-1.30). Conclusions: This population study provides evidence that patients with heart disease are at an elevated risk of developing CKD. Hypertension and diabetes mellitus are also comorbidity associated with increasing the CKD risk independently. [ABSTRACT FROM AUTHOR]
