Patients' reports of hypoglycaemic symptoms are common in European outpatients with type 2 diabetes and are associated with significantly lower treatment satisfaction and with barriers to adherence. In addition, being at HbA1C goal is associated with treatment satisfaction and adherence.

OBJECTIVE -We sought to develop stroke risk equations for Chinese patients with type 2 diabetes in Hong Kong. RESEARCH DESIGN AND METHODS -A total of 7,209Hong Kong Chinese type 2 diabetic patients without a history of stroke at baseline were analyzed. The data were randomly and evenly divided into the training subsample and the test subsample. In the training subsample, stepwise Cox models were used to develop the risk equation. Validation of the U.K. Prospective Diabetes Study (UKPDS) stroke risk engine and the current stroke equation was performed in the test dataset. The life-table method was used to check calibration, and the area under the receiver operating characteristic curve (aROC) was used to check discrimination.RESULTS -A total of 372 patients developed incident stroke during a median of 5.37 years (interquartile range 2.88 -7.78) of follow-up. Age, A1C, spot urine albumin-to-creatinine ratio (ACR), and history of coronary heart disease (CHD) were independent predictors. The performance of the UKPDS stroke engine was suboptimal in our cohort. The newly developed risk equation defined by these four predictors had adequate performance in the test subsample. The predicted stroke-free probability by the current equation was within the 95% CI of the observed probability. The aROC was 0.77 for predicting stroke within 5 years. The risk score was computed as follows: 0.0634 ϫ age (years) ϩ 0.0897 ϫ A1C ϩ 0.5314 ϫ log 10 (ACR) (mg/mmol) ϩ 0.5636 ϫ history of CHD (1 if yes). The 5-year stroke probability can be calculated by: 1 Ϫ 0.9707 EXP (Risk Score Ϫ 4.5674) .CONCLUSIONS -Although the risk equation performed reasonably well in Chinese type 2 diabetic patients, external validation is required in other populations. Diabetes Care 30:65-70, 2007S troke is among the most common causes of death worldwide (1). Chinese individuals have a higher incidence of stroke and related mortality than Caucasians, as shown in the World Health Organization MONICA project (2). Diabetic patients have a two-to fivefold increased risk of stroke, in part due to interactions between multiple risk factors (3). The Framingham Study (4) and U.K. Prospective Diabetes Study (UKPDS) (5) have developed risk equations based on data collected from the Caucasian community and diabetic patients. Although a stroke risk equation has been developed in a small cohort of Chinese men recruited from a workforce (6), there is currently no risk equation applicable to Chinese individuals with diabetes, despite this number being projected to 42.3 million by 2030 (7). In this study, we validate and develop stroke risk equations to predict first stroke in Chinese type 2 diabetic patients based on data from the Hong Kong Diabetes Registry. RESEARCH DESIGN AND METHODS-Since 1995, all newly referred diabetic patients to the Prince of Wales Hospital in Hong Kong underwent comprehensive assessments of complications and risk factors based on the European DiabCare protocol (7a). Patients with hospital admissions within 6 -8 weeks before assessment accounted for...

Estimated GFR, haematocrit and ACR were independent predictors of ESRD and the derived risk equation performed well in Chinese patients with type 2 diabetes.

The main objective of this study was to describe real-world treatment persistence with subcutaneous tumor necrosis factor-alpha inhibitors (SC-TNFi) in patients with ankylosing spondylitis, psoriatic arthritis, or rheumatoid arthritis [collectively immune-mediated rheumatic disease, (IMRD)] in Sweden. A secondary objective was to describe potential effects on health care resource utilization (HCRU) cost from non-persistence. Patients were identified through filled prescriptions for adalimumab (ADA), etanercept (ETA), certolizumab pegol (CZP), and golimumab (GLM) between 5/6/2010 and 12/31/2012 from the Swedish Prescribed Drug Register. Persistence was estimated using survival analysis. Costs were derived from HCRU and comprised specialized outpatient care, inpatient care and non-disease-modifying antirheumatic drug medications. A total of 4903 patients were identified (ADA: 1823, ETA: 1704, CZP: 622, GLM: 754). Comparisons over 3 years showed that GLM had significantly higher persistence than ADA (p = 0.022) and ETA (p = 0.004). The mean difference in non-biologic HCRU costs between persistent and non-persistent patients was higher after compared to before the start of biologic therapy. SC-TNFi-naïve IMRD patients initiating treatment with GLM had significantly higher persistence rates than patients initiating treatment with ADA or ETA in Sweden. Furthermore, persistence rates observed in the study were lower than those observed in clinical trials, highlighting the need for an all-party (provider-patient-payer-drug manufacturer) engagement and development of programs to increase persistence rates in clinical practice, thus leading to improved clinical outcomes. In addition, the results of this study indicate that persistence to treatment with SC-TNFi may be associated with cost offsets in terms of non-biologic costs.

The occurrence and severity of hypoglycaemic symptoms were associated with increased patient worry about hypoglycaemia and lower health-related quality of life among type 2 diabetic patients being treated with both metformin and a sulphonylurea.

Patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) are frequently treated with subcutaneous biologic therapies when disease progresses or when response to synthetic disease-modifying antirheumatic drugs (DMARDs) is inadequate. This study analyzed treatment persistence and treatment patterns for RA, AS, and PsA patients in Germany initiating subcutaneous biologic therapies with and without prior DMARDs use. A retrospective cohort study was conducted using the Electronic Medical Record database of IMS Disease Analyzer, Germany. Patients who were ≥18 years old; had at least one ICD-10 diagnosis code of RA, AS, or PsA during the study period; and had exposure to a subcutaneous biologic agent between January 1, 2009 and June 30, 2012 were selected. Patients were required to have continuous observation ≥12 months prior to and after index medication date. Persistence was defined as consecutive days from treatment initiation until treatment discontinuation (≥60-day lapse in medication coverage). Patients were stratified by pre-index use of DMARDs. Kaplan-Meier analysis was conducted to assess time to discontinuation, and logistic regression was conducted to identify characteristics associated with persistence. A total of 576 RA, 108 AS, and 197 PsA patients without biologic experience during the pre-index period were selected. The percentages of RA, AS, and PsA patients persistent ≥12 months were 51.9, 48.1, and 57.9 %, respectively. Median persistent time over 12 months was 365.0 days for RA (mean 245.9 days), 281.0 for AS (mean 228.5), and 365.0 for PsA (mean 264.1). In the RA cohort, a significantly higher proportion of those with pre-index DMARD use were persistent compared to those without pre-index DMARD (56.1 vs. 33.3 %, p = 0.0001). No significant differences were observed for the AS and PsA cohorts. Multivariate analyses confirmed that DMARD-experienced patients were 2.45 times more likely to be persistent with subcutaneous biologic therapy in the RA cohort. Switching between subcutaneous biologics occurred in <10 % of patients in all three cohorts. In the subpopulations with at least two prescriptions for the index subcutaneous biologic and who remained persistent on the index subcutaneous biologic, dose escalation of ≥50 % occurred in 50, 60, and 49 % in the RA, AS, and PsA cohorts, respectively. Among RA, AS, and PsA patients newly initiating subcutaneous biologic agents in Germany, persistence at 12 months is relatively low (48-58 %). For the RA cohort, patients with pre-index DMARD use are more persistent than patients without. The majority of patients do not switch between subcutaneous biologics. A notable proportion of patients who remained persistent on their index subcutaneous biologic had a dose escalation. There are opportunities to improve outcomes of patient with rheumatoid disease through improved medication persistence.
