Abstract
In this review, we aim to show how person-reported outcomes (PROs) and person-reported experiences (PREs) can significantly contribute to the way diabetes care is delivered, the involvement of people with diabetes in diabetes care, and the collaboration between health care professionals and people with diabetes. This review focuses on the definition and measurement of PROs and PREs, the importance of PROs and PREs for person-centred diabetes care, and integrating the perspectives of people with diabetes in the evaluation of medical, psychological and technological interventions. PROs have been increasingly accepted by Health Technology Assessment bodies and are therefore valued in the context of reimbursement decisions and consequently by regulators and other health care stakeholders for the allocation of health care resources. Furthermore, the review identified current challenges to the assessment and use of PROs and PREs in clinical care and research. These challenges relate to the combination of questionnaires and ecological momentary assessment for measuring PROs and PREs, lack of consensus on a core outcome set, limited sensitivity to change within many measures and insufficient standardization of what can be considered a minimal clinically important difference. Another issue that has not been sufficiently addressed is the involvement of people with diabetes in the design and development of measures to assess PROs and PREs.

Abstract
Background It is unknown if initiation of a sodium-glucose cotransporter-2 inhibitor (SGLT-2i) is associated with changes in patient-reported health status outside of clinical trials. Methods and Results Using a prospective observational study design, adults with type 2 diabetes and cardiovascular disease were recruited from 14 US hospitals between November 2019 and December 2021 if they were new users of noninsulin antidiabetic medications. The primary outcome was change in 6-month diabetes treatment satisfaction. Secondary outcomes included diabetes-related symptom distress, diabetes-specific quality of life, and general health status for all patients and based on cardiovascular disease type. Inverse probability of treatment weight using propensity score was performed to compare outcome changes based on medication use. Of 887 patients (SGLT-2i: n=242) included in the inverse probability of treatment weight analyses, there was no difference in changes in treatment satisfaction in SGLT-2i users compared with other diabetes medication users (0.99 [95% CI, -0.14 to 2.13] versus 1.54 [1.08 to 2.00], P=0.38). Initiating an SGLT-2i versus other diabetes medications was associated with a greater reduction in ophthalmological symptoms (-3.09 [95% CI, -4.99 to -1.18] versus -0.38 [-1.54 to 0.77], P=0.018) but less improvement in hyperglycemia (1.08 [-2.63 to 4.79] versus -3.60 [-5.34 to -1.86], P=0.026). In subgroup analyses by cardiovascular disease type, SGLT-2i use was associated with a greater reduction in total diabetes symptom burden and neurological sensory symptoms in patients with heart failure. Conclusions Among patients with type 2 diabetes and cardiovascular disease, initiating an SGLT-2i was not associated with changes in diabetes treatment satisfaction, total diabetes symptoms, diabetes-specific quality of life, or general health status.

Abstract
The assessment and management of patient-reported outcomes (PROs) is considered secondary to that of cardiometabolic outcomes. When assessed, health-related quality of life (HRQOL), a PRO, can yield pertinent information that cannot be obtained from cardiometabolic assessments. For instance, physical and mental distress can be quantified and treated. Moreover, treatment convenience and satisfaction can be gaged. Behavioral modification, bariatric surgery, and pharmacotherapy can improve PROs. Typically, HRQOL is responsive to changes in weight. Specifically, weight loss and weight gain are associated with positive and negative changes in quality of life, respectively. In addition, patient satisfaction can be influenced by glycemic control. Therefore, hypoglycemia and hyperglycemic episodes can negatively affect patient satisfaction. When managing type 2 diabetes (T2D), it is important to consider how therapies impact PROs. Generally, changes in clinical outcomes mirror changes in PROs. To best manage T2D, integrating the assessment of PROs with clinical outcomes is needed.

Abstract
BACKGROUND Angiotensin-converting enzyme inhibitors have been used as the standard of care for the treatment of diabetic nephropathy. Recently, dapagliflozin has been shown to reduce diabetic nephropathy when added to the standard of care. OBJECTIVE The objective of this study was to determine the cost effectiveness of dapagliflozin added to the standard of care in diabetic nephropathy in the United States of America (USA). METHODS A Markov model was developed to determine the cost-effectiveness outcomes from the Medicare/Medicaid health coverage perspective. Model inputs were derived from the literature. The primary outcomes were total costs, quality-adjusted life-years (QALYs), and the incremental cost-effectiveness ratio. Deterministic and probabilistic sensitivity analyses were performed to determine the robustness of our results. A willingness-to-pay threshold of $100,000 per QALY was applied, which is based on previous studies. RESULTS Dapagliflozin yielded a lifetime QALY of 2.8. The discounted QALY associated with the standard of care was 2.6. The standard of care was the less costly treatment with a lifetime cost of $106,150.25 as compared with dapagliflozin, which costs $110,689.25. Dapagliflozin demonstrated an incremental cost-effectiveness ratio of $21,141.51 per additional QALY. The most influential parameters of the incremental cost-effectiveness ratio were the adverse drug reaction-related cost of the standard of care and dapagliflozin, the acquisition cost, and the adverse drug reaction-related cost of dapagliflozin. The effects and costs of the interventions were consistent between base-case analyses and the probabilistic model (incremental cost-effectiveness ratio: $19,023.35 [$13,637.8-$27,483.1]). CONCLUSIONS Dapagliflozin added to the standard of care was cost effective relative to the standard of care alone in the USA for patients with diabetic nephropathy.

Abstract
INTRODUCTION Treatment-related quality of life (QOL) is an important aspect of diabetes management. We evaluated the influence of a sodium-glucose cotransporter 2 (SGLT2) inhibitor, tofogliflozin, on treatment-related QOL in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS This is the prespecified subanalysis study of the "Using TOfogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA)" trial. Treatment-related QOL was evaluated at baseline, week 26, week 52, and week 104 after the initiation of the study using the Diabetes Therapy-Related QOL questionnaire (DTR-QOL). Among the 340 patients in the original UTOPIA study, a total of 252 patients (127, tofogliflozin group; 125, conventional treatment group) who completed the DTR-QOL questionnaire at baseline were the study subjects of the current subanalysis. RESULTS The tofogliflozin and conventional treatment groups exhibited almost comparable baseline clinical characteristics, while the use of antihypertensive drugs and lipid-lowering agents was significantly lower in the tofogliflozin treatment group than in the conventional treatment group. Tofogliflozin treatment increased the total score of DTR-QOL7 from baseline (P < 0.001), while conventional treatment did not change it. There were statistically significant differences in delta change in the total DTR-QOL7 score and DTR-QOL7 Q4, Q5, Q6, and Q7 scores from the baseline to week 104 between the treatment groups. Delta changes in HbA1c (Spearman's correlation coefficient, ρ = - 0.30, P < 0.001), fasting blood glucose (ρ = - 0.16, P = 0.031), BMI (ρ = - 0.19, P = 0.008), and waist circumference (ρ = - 0.17, P = 0.024) at week 104 were negatively associated with delta change in the total QOL7 score. CONCLUSIONS Our data indicated that tofogliflozin treatment improved treatment-related QOL compared to conventional treatment in Japanese patients with T2DM, in accordance with the improvement of major cardiovascular risk factors.

Abstract
Background/aim To evaluate the impact of treatment with sodium-glucose co-transporter-2 (SGLT2) Inhibitors on quality of life (QoL), sleep quality (SQ), and anxiety levels in patients with Type 2 diabetes mellitus (T2DM). Materials and methods Ninety-seven patients with type 2 diabetes admitted to tertiary care hospital diabetes clinic were included. Fifty patients were randomized to receive SGLT2 inhibitors in addition to baseline treatment (Group A), 47 subjects continued with their baseline treatment or were added other medications as needed (Group B). Thirty healthy controls (HC) were recruited (Group C). All groups were subjected to the Turkish version of Short Form-36 (SF-36), Pittsburgh Sleep Quality (PSQ), and Beck Anxiety Inventory (BAI) scales both at baseline and final visit. Results Physical function, emotional role limitation, vitality, mental health, pain, general health perception scores of SF-36 were significantly improved in Group A, at the end of the follow-up period. There was no significant change in terms of PSQ, BAI scores, and hypoglycaemia documented in all groups. The intervention-related change in HbA1c level, body weight, and body mass index were significantly higher in Group A. Conclusion The QoL was improved in people with diabetes who were taking SGLT2 inhibitors. This may be explained by weight loss observed in participants.

Abstract
INTRODUCTION No study has compared the effects of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and dipeptidyl peptidase 4 inhibitors (DPP4is) on patients' quality-of-life (QOL). METHODS We enrolled 253 drug-naïve Japanese patients with type 2 diabetes mellitus (T2DM), randomly assigned them into a dapagliflozin (SGLT2i) group or DPP4i group in approximately 1:1 ratio, and monitored them for 24 weeks. The primary endpoint was the proportion of subjects indicating improvement in the "overall quality of life" domain of SHIELD-WQ-9 at week 24. Secondary endpoints included other domains of SHIELD-WQ-9, DTR-QOL, EQ-5D-5L, medication preference, medication adherence, diet therapy adherence, body weight, body mass index (BMI), abdominal circumference, HbA1c, and frequency of adverse events. RESULTS The proportion of subjects indicating improvement in the "overall quality of life" domain of SHIELD-WQ-9 at week 24 was higher in the dapagliflozin group (28.4%) than in the DPP4i group (18.6%) (p = 0.08). The proportion of subjects indicating improvement in the "physical health" domain of SHIELD-WQ-9 at week 24 was significantly higher in the dapagliflozin group (42.2%) than in the DPP4i group (23.7%) (p = 0.004). Total scores and domain 1 scores of DTR-QOL showed greater improvement in the dapagliflozin group (14.3 ± 15.6 and 15.5 ± 20.8, respectively) than in the DPP4i group (10.2 ± 15.6 and 10.3 ± 19.5, respectively) (both p = 0.05). EQ-5D-5L scores had significantly improved in the DPP4i group (0.023 ± 0.088) (p = 0.005); the intergroup difference was not significant (p = 0.14). Body weight (p < 0.001), BMI (p < 0.001), and abdominal circumference (p = 0.019) had significantly decreased in the dapagliflozin group compared with the corresponding values in the DPP4i group. CONCLUSION Dapagliflozin showed a comparable or more favorable benefit on Japanese patients' QOL compared with DPP4is. Dapagliflozin was well tolerated. It significantly reduced body weight, which was significantly correlated with improvement in the patients' QOL. This study demonstrates that dapagliflozin can be used as a first-line drug for T2DM in Japan with a beneficial impact on patients' QOL.

Abstract
Objective: To assess patient-reported outcomes after two years of use of dual oral anti-diabetes drug (OAD) therapy in elderly people (≥65 years) with type 2 diabetes mellitus (T2DM) from Italy under real-life settings.Methods: 3-AGE was a prospective, non-interventional study in elderly people with T2DM inadequately controlled on metformin monotherapy (defined as glycated hemoglobin [HbA1c] 7.0-9.0%), in whom a second OAD was prescribed. Primary endpoint was to assess the physical and psychological symptoms associated with T2DM from baseline to 24 months using the Diabetes Symptom Check List revised (DSC-R) questionnaire. Patient's quality of life and health status, treatment satisfaction, consumption of healthcare resources, and physician satisfaction with treatment were also assessed (secondary endpoints) using validated questionnaires. Additionally, safety and clinical characteristics were also evaluated.Results: The mean age of the study population (N = 860) was 71.5 ± 5.2 years. Addition of a second OAD significantly (p < .0001) reduced the DSC-R score from baseline (0.73 ± 0.68) to both Months 12 and 24 (0.63 ± 0.59 and 0.61 ± 0.56), and HbA1c from baseline (7.72% ± 0.54%) to Month 12 (6.95% ± 0.82%). Adding a second OAD improved quality of life and health status (baseline, 71.31 ± 15.16 to Month 12, 74.49 ± 13.64; p < .0001), patient's treatment satisfaction (p < .0001), and consumption of healthcare resources per patient. Physicians expressed good satisfaction with patients' treatment (across efficacy, tolerability and compliance domains) at Month 12. Overall, 32 adverse reactions (in 24 patients) and four hypoglycemic episodes were reported during the 24 months.Conclusion: Addition of a second OAD improved physical and psychological symptoms associated with T2DM and was well tolerated in elderly people under real-life settings.

Abstract
Many blood glucose-lowering drugs cannot be used once patients with type 2 diabetes (T2D) and nonalcoholic fatty liver disease develop nonalcoholic steatohepatitis (NASH). Therefore, such patients often require insulin treatment. We aimed to determine the effect of sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin monotherapy on glucose metabolism in a mouse model of NASH/T2D, with a focus on its diuretic effects. To imitate ascites and to determine its severity by imaging, meglumine sodium amidotrizoate (MSA) was infused into the abdominal cavities of mice. The reduction in ascites induced by dapagliflozin was compared with that induced by furosemide using microcomputed tomography. The effects of each drug on hemodynamics were also compared. A dapagliflozin-related improvement in glucose tolerance was achieved in mice fed a high-fat diet (HFD) or an HFD + methionine-and-choline-deficient diet (MCDD). In dapagliflozin-treated NASH mice, hypoglycemia was not identified during 24-hour casual blood glucose monitoring. In the dapagliflozin and furosemide-treated groups, the time taken for the resolution of artificial ascites was significantly shorter than in the untreated group, and there were no significant differences between these groups. Furosemide significantly reduced the blood pressure and significantly increased the heart rate of the mice. Dapagliflozin caused a mild decrease in systolic, but not diastolic blood pressure, and the heart rate and circulating catecholamine and renin-aldosterone concentrations were unaffected. Dapagliflozin treatment improved glycemic control in the NASH mice versus untreated mice. Thus, dapagliflozin had a prompt diuretic effect but did not adversely affect the hemodynamics of mice with NASH and T2D. Therefore, it may be useful for the treatment of patients with both T2D and liver cirrhosis.

Abstract
BACKGROUND Assessing the quality of life (QOL) for patients with type 2 diabetes is an essential part of diabetes management, especially for the evaluation of new antidiabetic treatments and glucose monitoring technologies. Accordingly, the aim of this study was to assess QOL according to treatment types. METHODS This cross-sectional study included 170 patients with type 2 diabetes from the region of Melk in Lower Austria. Of the patients 61 used only oral antidiabetic agents (OAD) and 109 patients were treated with insulin (with or without OAD). The QOL was assessed in patients using sodium-glucose cotransporter 2 inhibitors (SGLT2 inhibitors). Among the 170 patients with type 2 diabetes 95 used SGLT2 inhibitors. The World Health Organization Quality of Life BREF (WHOQOL-BREF) assessment was used to assess QOL among these patients. The Mann-Whitney U-test was utilized in this study and a P value <0.05 was considered statistically significant. RESULTS Regarding the 170 participants, most were male (58.82%) and the mean glycated hemoglobin (HbA1c) level was 55.46 ± 12.30 mmol/mol (7.2%). The WHOQOL-BREF scores among type 2 diabetes patients were relatively high, which reflect a good QOL and the mean physical, psychological, social and environmental domain scores were 64.53 ± 20.15, 71.29 ± 18.08, 70.10 ± 20.08, and 84.419 ± 11.22 SD, respectively. There were no statistically significant differences in WHOQOL scores of the domains between the insulin-treated group and OAD group and between the group treated with SGLT2 inhibitors and the group not treated with SGLT2 inhibitors. CONCLUSION This study showed no QOL distinctions between treatment groups in patients with type 2 diabetes; however, a large cohort study is needed to examine these groups further.

Abstract
AIMS To assess baseline and change after 26-weeks in health-related quality of life (HRQoL) among adults with type 2 diabetes mellitus (T2DM) initiating one of the new glucose lowering drugs (GLD) in daily practice. METHODS Inception cohort of patients who initiated one of dipeptidyl peptidase 4 inhibitors (DPP-4), glucagon-like peptide-1 analogues (GLP-1) or sodium-glucose cotransporter inhibitors (SGLT2) drugs. A baseline questionnaire collected socio-demographic and self-reported clinical data. HRQoL was assessed by the Euroqol-5D. Participants were divided into: (1) incident new users (INU) (who used for the first time one of the monitored GLD and had no current or prior experience with DPP-4/GLP-1/SGLT2) and (2) prevalent new users (PNU) (who had previously used at least one GLD of the monitored drug classes, but not the inception drug). Multivariate regression explored factors associated with a meaningful change in HRQoL. RESULTS 1303 patients. Over 26weeks, a mean positive change in the EQ-5D scores, were observed. No differences between INU and PNU were found. Participants with worse health conditions (e.g. presence and number of chronic diseases, obese) at baseline were more likely to experience larger improvements in HRQoL. CONCLUSIONS Over 26-weeks, T2DM patients starting with, or switching to new GLD maintained or modestly increased their HRQoL.

Abstract
OBJECTIVE The frequency of hypoglycemia in patients with T1DM is high and results in a poorer quality-of-life and low treatment satisfaction. The aim of this study is to demonstrate the effect of changing the basal insulin (glargine or detemir) to insulin degludec. METHODS An observational analytical study was conducted on a cohort of 110 patients with T1DM. The patients were administered three questionnaires to assess treatment satisfaction (DTSQ-s), fear of hypoglycemia (HFS-II) and quality-of-life (EQ-5D), before the change and at 6 months. A statistical analysis was performed for repeated measures. RESULTS The 110 patients with T1DM had a mean diabetes duration of 19.1 (11.6) years, 53.6% were men, the mean age was 43.4 (15.4) years, and the mean BMI was 25.2 (4.2) kg/m2. After 6 months, there was a significant reduction in baseline fasting plasma glucose (from 159.1 [68.6] to 132.9 [56.6] mg/dL; p < .001) and HbA1c levels (from 7.82% [1.2] to 7.6% [1.2]; p = .002). A reduction in the number of severe hypoglycemic episodes (0.17 [0.5] vs 0.05 [0.2]; p = .03) was observed. At 6 months, an improvement in the DTSQ-s (from 24.3 [5.5] to 27.3 [5.4]; p < .001) was observed. There was a decrease in the mean number of perceived hypoglycemia (from 2.9 [1.4] to 2.3 [1.4]; p = .003) and hyperglycemia (from 3.5 [1.3] to 2.7 [1.4]; p < .001). There was also a decrease in the mean HFS-II score (from 24.1 [14.0] to 20.0 [13.0]; p < .001). There were no significant differences in the EQ-5D index (from 0.91 [0.14] to 0.89 [0.16]; p = .13). However, there was significant improvement in the EQ-5D as measured by VAS (from 70.5 [16.5] to 73.6 [14.4]; p = .04). CONCLUSIONS The change to insulin degludec in patients with T1DM improved their metabolic control, increased their satisfaction with the insulin therapy, and offered them improved quality-of-life.

Abstract
BACKGROUND The benefits of sodium glucose cotransporters 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus include plasma glucose control, reduction in body weight and blood pressure, and low risk of hypoglycemia, although they may also cause genitourinary infections, polyuria, or volume depletion. It is not clear whether dapagliflozin, an SGLT2 inhibitor, improves treatment satisfaction among patients in a comprehensive way despite the negative side effects. This study assessed the effect of dapagliflozin on glycosylated hemoglobin (HbA1c), body weight, and treatment satisfaction in overweight patients with type 2 diabetes mellitus treated with oral hypoglycemic agents. METHODS This multicenter, open-label, single-arm observational study included patients with type 2 diabetes mellitus administering dapagliflozin 5 or 10 mg per day for 14 weeks. Changes in treatment satisfaction were evaluated using a new version of the Oral Hypoglycemic Agent-Questionnaire (OHA-Q ver. 2) consisting of 23 items. Correlation between treatment satisfaction and HbA1c levels and body weight were analyzed using the Spearman's rank-correlation coefficient. RESULTS Of the 221 patients enrolled, 188 completed the study. Mean HbA1c decreased from 7.8 ± 0.7% (62.1 ± 7.5 mmol/mol) to 7.3 ± 0.8% (55.9 ± 8.7 mmol/mol) (change - 0.6 ± 0.7%, P < 0.001) and body weight decreased from 82.5 ± 14.6 to 80.7 ± 14.8 kg (change - 2.3 ± 2.8 kg, P < 0.001). OHA-Q ver. 2 was validated as well, the mean OHA-Q ver. 2 total score increased from 44.3 ± 9.4 to 46.6 ± 9.8 (best score 69, worst score 0; change 2.3 ± 6.6, P < 0.001). The change in body weight significantly correlated with the OHA-Q ver. 2 total score (Spearman's ρ = - 0.17, P = 0.035). The change in HbA1c levels significantly correlated with the satisfaction subscale score (Spearman's ρ = - 0.19, P = 0.011). CONCLUSIONS Dapagliflozin significantly improved treatment satisfaction among patients with type 2 diabetes mellitus for 14 weeks. Body weight loss significantly correlated with treatment satisfaction.Trial registration UMIN-CTR: UMIN000016304.

Abstract
OBJECTIVE To identify and define clinically meaningful type 1 diabetes outcomes beyond hemoglobin A1c (HbA1c) based upon a review of the evidence, consensus from clinical experts, and input from researchers, people with type 1 diabetes, and industry. Priority outcomes include hypoglycemia, hyperglycemia, time in range, diabetic ketoacidosis (DKA), and patient-reported outcomes (PROs). While priority outcomes for type 1 and type 2 diabetes may overlap, type 1 diabetes was the focus of this work. RESEARCH AND METHODS A Steering Committee-comprising representatives from the American Association of Clinical Endocrinologists, the American Association of Diabetes Educators, the American Diabetes Association, the Endocrine Society, JDRF International, The Leona M. and Harry B. Helmsley Charitable Trust, the Pediatric Endocrine Society, and the T1D Exchange-was the decision-making body for the Type 1 Diabetes Outcomes Program. Their work was informed by input from researchers, industry, and people with diabetes through Advisory Committees representing each stakeholder group. Stakeholder surveys were used to identify priority outcomes. The outcomes prioritized in the surveys were hypoglycemia, hyperglycemia, time in range, DKA, and PROs. To develop consensus on the definitions of these outcomes, the Steering Committee relied on published evidence, their clinical expertise, and feedback from the Advisory Committees. RESULTS The Steering Committee developed definitions for hypoglycemia, hyperglycemia, time in range, and DKA in type 1 diabetes. The definitions reflect their assessment of the outcome's short- and long-term clinical impact on people with type 1 diabetes. Knowledge gaps to be addressed by future research were identified. The Steering Committee discussed PROs and concluded that further type 1 diabetes-specific development is needed. CONCLUSIONS The Steering Committee recommends use of the defined clinically meaningful outcomes beyond HbA1c in the research, development, and evaluation of type 1 diabetes therapies.

Abstract
In type 2 diabetes (T2D), early combination therapy using agents that target a number of the underlying pathophysiologic defects contributing to hyperglycemia may improve patient outcomes. For many patients, the combination of metformin with a sodium-glucose cotransporter-2 (SGLT-2) inhibitor may be a good option because these agents have complementary mechanisms of action, neutral-to-positive effects on body weight, and a low risk of hypoglycemia. This review focuses on the combination of metformin with dapagliflozin, a member of the SGLT-2 inhibitor class of antidiabetes agents. In clinical trials, the combination of dapagliflozin with metformin produced significant and sustained reductions in glycated hemoglobin and body weight in a broad range of adult patients with T2D, including those initiating pharmacotherapy and those with more advanced disease. These reductions were accompanied by modest decreases in blood pressure. Dapagliflozin as add-on therapy to metformin was well tolerated and associated with low rates of hypoglycemia. Genital infections and, in some studies, urinary tract infections were more frequent with dapagliflozin than with placebo. Early combination therapy with dapagliflozin and metformin may be a safe and appropriate treatment option that enables patients with T2D to achieve individualized glycemic goals as either initial combination therapy in treatment-naïve patients or as dapagliflozin add-on in patients inadequately controlled with metformin therapy.

Abstract
Patients with type 2 diabetes (T2DM) and inadequate glycaemic control on combination metformin (MET) and sulphonylurea (SU) were enrolled in a 24-week, double-blind, randomized, placebo-controlled study with a 28-week extension. The five-dimension EuroQol questionnaire (EQ-5D), SHIELD Weight Questionnaire-9 (WQ-9), Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) were used to evaluate health status and health-related quality of life (HRQoL) at baseline and week 52. Patients with dapagliflozin 10 mg + MET + SU (n = 108) were compared with patients treated with placebo + MET + SU (n = 108), using a repeated-measures mixed model. EQ-5D visual analogue scale scores, IWQOL-Lite and DTSQ scores improved in the dapagliflozin and placebo groups from baseline to week 52; however, there was no significant difference between groups (p > 0.20). EQ-5D index scores remained the same from baseline to week 52 for dapagliflozin and placebo (p = 0.54). A numerically greater proportion of the dapagliflozin group reported improvement in all nine SHIELD WQ-9 items compared with placebo, and the difference was statistically significant for physical health (p = 0.017). Over 52 weeks of therapy, patients maintained their health status and HRQoL when dapagliflozin was added to the treatment.

Abstract
Background The EQ-5D instrument is arguably the most well-known and commonly used generic measure of health status internationally. Although the instrument has been employed in outcomes studies of diabetes mellitus in many countries, it has not yet been used in Nigeria. Objective This study was carried out to assess the sensitivity of the EQ-5D instrument in a sample of Nigerian patients with type 2 diabetes mellitus (T2DM). Methods A cross-sectional study was conducted using the EQ-5D instrument to assess the self-reported quality of life of patients with T2DM attending two tertiary healthcare facilities in south eastern Nigeria consenting patients completed the questionnaire while waiting to see a doctor. A priori hypotheses were examined using multiple regression analysis to model the relationship between the dependent variables (EQ VAS and EQ-5D Index) and hypothesized independent variables. Results A total of 226 patients with T2DM participated in the study. The average age of participants was 57 years (standard deviation 10 years) and 61.1 % were male. The EQ VAS score and EQ-5D index averaged 66.19 (standard deviation 15.42) and 0.78 (standard deviation 0.21) respectively. Number of diabetic complications, number of co-morbidities, patient’s age and being educated predicted EQ VAS score by −6.76, −6.15, −0.22, and 4.51 respectively. Also, number of diabetic complications, number of co-morbidities, patient’s age and being educated predicted EQ-5D index by −0.12, −0.07, −0.003, and 0.06 respectively.. Conclusion Our findings indicate that the EQ-5D could adequately capture the burden of type 2 diabetes and related complications among Nigerian patients.

Dapagliflozin is a selective and reversible inhibitor of sodium-glucose linked transporter type 2 (SGLT2), which mediates approximately 90% of active renal glucose reabsorption in the early proximal tubule of the kidney. Dapagliflozin significantly reduces glucose reabsorption and decreases serum glucose concentration in an insulin-independent manner. The decrease of glucose reabsorption by dapagliflozin has also been associated with a reduction in body weight. Furthermore, the drug modestly reduces blood pressure levels through weight loss and its action as osmotic diuretic. Dapagliflozin has been approved as monotherapy in patients with type 2 diabetes mellitus (T2DM) who cannot tolerate metformin or in combination with other antidiabetic drugs, with the exception of pioglitazone due to the theoretical increased risk of bladder cancer. The drug should not be prescribed in patients with moderate or severe renal impairment or in patients at risk for developing volume depletion. Dapagliflozin is associated with increased incidence of genital and lower urinary tract infections, but these infections are usually mild to moderate and respond to standard antimicrobial treatment. Based on current evidence, dapagliflozin is a useful drug for patients with T2DM with a favorable safety profile. However, further research regarding the effects of dapagliflozin on cardiovascular outcomes is needed.

Abstract
INTRODUCTION Dapagliflozin (DAPA) (Farxiga or Forxiga) is a sodium glucose cotransporter 2 (SGLT2) inhibitor approved for type 2 diabetes mellitus(T2DM) treatment. AREAS COVERED The review focuses on the pharmacokinetics (PK), pharmacodynamics(PD) and clinical studies published on DAPA. The authors searched PubMed database for English language studies describing DAPA characteristics and use in T2DM subjects published through June 2014. EXPERT OPINION DAPA exhibits favorable PK and PD properties and is effective in reducing glycemic levels. In addition, DAPA shows beneficial/neutral effects on other risk factors contributing to T2DM metabolic control. Increased risk of genital and urinary infections and episodes of volume depletion represent the major concerns for its use. FDA requires additional data to assess imbalances in bladder cancer and drug cardiovascular safety. The mechanism of action and the very low risk of drug-drug interaction make it an ideal drug for rapidly reducing glucotoxicity and restoring clinical response to other antidiabetic drugs.
