RESUMEN

BACKGROUND AND AIMS: Noninvasive biomarkers provide prognostic information for the development of major adverse liver outcomes (MALOs) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), but the predictive value of longitudinal biomarker measurements has not been evaluated. We assessed whether changes in biomarkers could predict incident MALO in MASLD. APPROACH AND RESULTS: We analyzed a cohort of 1260 patients (71.7% on biopsy) with non-cirrhotic MASLD between 1974 and 2019. Data at baseline and follow-up visits were obtained from medical charts. MALO was determined through medical charts and linkage to national registers until the end of 2020. A joint modeling approach was used to quantify the associations between the trajectory of biomarkers and the risk of MALO. MASLD was diagnosed at a median age of 52 years (IQR: 39-60), and 59% were male. During a median follow-up of 12.2 years, 111 (8.8%) patients developed MALO. The joint modeling showed that an elevated fibrosis-4 score (HR: 2.60, 95% CI: 1.89-3.50), aspartate aminotransferase (HR: 2.69, 95% CI: 2.57-3.05), and lower platelet count (HR: 0.93, 95% CI: 0.90-0.97) at any time point were associated with an increased risk of MALO, whereas the rate of change in these biomarkers had no association with this risk. CONCLUSIONS: In addition to baseline measurements of noninvasive biomarkers such as fibrosis-4 score, aspartate aminotransferase, and platelets taken at MASLD diagnosis, monitoring their values over time is important, as the latest value of these biomarkers is closely associated with the risk of future MALO. The rate of change may not be as important.

RESUMEN

Background & Aims: Long-term studies of the prognosis of NAFLD are scarce. Here, we investigated the risk of major adverse liver outcomes (MALO) in a large cohort of patients with NAFLD. Methods: We conducted a cohort study with data from Swedish university hospitals. Patients (n = 1,260) with NAFLD without cirrhosis were diagnosed through biopsy or radiology, and had fibrosis estimated through vibration-controlled transient elastography, biopsy, or FIB-4 score between 1974 and 2020 and followed up through 2020. Each patient was matched on age, sex, and municipality with up to 10 reference individuals from the general population (n = 12,529). MALO were ascertained from Swedish national registers. The rate of events was estimated by Cox regression. Results: MALO occurred in 111 (8.8%, incidence rate = 5.9/1,000 person-years) patients with NAFLD and 197 (1.6%, incidence rate = 1.0/1,000 person-years) reference individuals during a median follow up of 13 years. The rate of MALO was higher in patients with NAFLD (hazard ratio = 6.6; 95% CI = 5.2-8.5). The risk of MALO was highly associated with the stage of fibrosis at diagnosis. In the biopsy subcohort (72% of total sample), there was no difference in risk between patients with and without non-alcoholic steatohepatitis. The 20-year cumulative incidences of MALO were 2% for the reference population, 3% for patients with F0, and 35% for F3. Prognostic information from biopsy was comparable to FIB-4 (C-indices around 0.73 vs. 0.72 at 10 years). Conclusions: This study provides updated information on the natural history of NAFLD, showing a high rate of progression to cirrhosis in F3 and a similar prognostic capacity of non-invasive tests to liver biopsy. Impact and implications: Several implications for clinical care and future research may be noted based on these results. First, the risk estimates for cirrhosis development are important when communicating risk to patients and deciding on clinical monitoring and treatment. Estimates can also be used in updated health-economic evaluations, and for regulatory agencies. Second, our results again highlight the low predictive information obtained from ascertaining NASHstatus by histology and call for more objective means by which to define NASH. Such methods may include artificial intelligence-supported digital pathology. We highlight that NASH is most likely the causal factor for fibrosis progression in NAFLD, but the subjective definition makes the prognostic value of a histological NASH diagnosis of limited value. Third, the finding that prognostic information from biopsy and the very simple Fibrosis-4 score were comparable is important as it may lead to fewer biopsies and further move the field towards non-invasive means by which to define fibrosis and, importantly, use non-invasive tests as outcomes in clinical trials. However, all modalities had modest discriminatory capacity and new risk stratification systems are needed in NAFLD. Repeated measures of non-invasive scores may be a potential solution.

RESUMEN

INTRODUCTION AND OBJECTIVES: Data on the prevalence of non-alcoholic fatty liver disease (NAFLD) in subgroups of the United States (US) population are limited. This study was conducted to estimate NAFLD prevalence overall and by subgroups, and prevalence of NAFLD with advanced fibrosis. MATERIALS AND METHODS: Using the National Health and Nutrition Examination Survey (NHANES) 2011-2018 data, a cross-sectional study was conducted. NAFLD was defined as having a US Fatty Liver Index (USFLI) ≥ 30 in the absence of other causes of liver disease, including excessive alcohol intake, chronic hepatitis B, and chronic hepatitis C. Likelihood for having advanced fibrosis was determined by the calculated NAFLD fibrosis score (NFS; high ≥ 0.676; low < -1.445) and fibrosis-4 index (FIB-4; high ≥ 2.67; low < 1.30). RESULTS: The weighted national prevalence of NAFLD in US adults was 26.7% (95% confidence interval: 25.3%-28.1%). Prevalence was higher among those aged ≥ 65 years, males, Mexican Americans, with BMI ≥ 35 kg/m2 (class 2 and 3 obesity) and with type 2 diabetes (T2D). Of those meeting the USFLI criterion for NAFLD, 18.1% and 3.7% were determined as having a high probability of advanced fibrosis based on NFS ≥ 0.676 and FIB-4 ≥ 2.67 cut-off values, respectively. CONCLUSIONS: This study supports an increased prevalence of NAFLD in specific subpopulations (aged ≥ 65 years, males, Mexican Americans, obese population, and patients with T2D). The observed difference in the prevalence of advanced fibrosis as estimated by NFS and FIB-4 highlights the challenge of choosing optimal cut-off values.

RESUMEN

Sternoclavicular joint instability is a rare complaint in the orthopedic clinic, but patients can experience chronic pain and functional impacts. Causes of instability may be posttraumatic, infectious, autoimmune, degenerative, or secondary to generalized laxity. Conservative treatment is the initial approach to management and involves activity modification, physical therapy, oral nonsteroidal anti-inflammatory drugs, and corticosteroid injections. Surgery is indicated when conservative treatment does not manage symptoms. Figure-of-eight reconstruction techniques provide greatest biomechanical strength but are associated with risk of neurovascular injury. Other reconstruction methods have been shown to mitigate these risks with favorable short-term outcomes.

RESUMEN

BACKGROUND & AIMS: This study assessed the effects of the glucagon-like peptide-1 (GLP-1)/glucagon receptor co-agonist efinopegdutide relative to the selective GLP-1 receptor agonist semaglutide on liver fat content (LFC) in patients with non-alcoholic fatty liver disease (NAFLD). METHODS: This was a phase IIa, randomized, active-comparator-controlled, parallel-group, open-label study. A magnetic resonance imaging-estimated proton density fat fraction assessment was performed to determine LFC at screening and Week 24. Participants with an LFC of ≥10% at screening were randomized 1:1 to efinopegdutide 10 mg or semaglutide 1 mg, both administered subcutaneously once weekly for 24 weeks. Participants were stratified according to the concurrent diagnosis of type 2 diabetes mellitus (T2DM). Both drugs were titrated to the target dose over an 8-week time period. The primary efficacy endpoint was relative reduction from baseline in LFC (%) after 24 weeks of treatment. RESULTS: Among 145 randomized participants (efinopegdutide n = 72, semaglutide n = 73), 33.1% had T2DM. At baseline, mean BMI was 34.3 kg/m2 and mean LFC was 20.3%. The least squares (LS) mean relative reduction from baseline in LFC at Week 24 was significantly (p <0.001) greater with efinopegdutide (72.7% [90% CI 66.8-78.7]) than with semaglutide (42.3% [90% CI 36.5-48.1]). Both treatment groups had an LS mean percent reduction from baseline in body weight at Week 24 (efinopegdutide 8.5% vs. semaglutide 7.1%; p = 0.085). Slightly higher incidences of adverse events and drug-related adverse events were observed in the efinopegdutide group compared with the semaglutide group, primarily related to an imbalance in gastrointestinal adverse events. CONCLUSIONS: In patients with NAFLD, treatment with efinopegdutide 10 mg weekly led to a significantly greater reduction in LFC than semaglutide 1 mg weekly. CLINICAL TRIAL NUMBER: EudraCT: 2020-005136-30; NCT: 04944992. IMPACT AND IMPLICATIONS: Currently, there are no approved therapies for non-alcoholic steatohepatitis (NASH). The weight loss associated with glucagon-like peptide-1 (GLP-1) receptor agonists has been shown to decrease hepatic inflammation in patients with NASH. In addition to reducing liver fat content (LFC) indirectly through weight loss, glucagon receptor agonism may also reduce LFC by acting on the liver directly to stimulate fatty acid oxidation and reduce lipogenesis. This study demonstrated that treatment of patients with non-alcoholic fatty liver disease with the GLP-1/glucagon receptor co-agonist efinopegdutide (10 mg weekly) led to a significantly greater reduction in LFC compared to treatment with the GLP-1 receptor agonist semaglutide (1 mg weekly), suggesting that efinopegdutide may be an effective treatment for NASH.

RESUMEN

BACKGROUND: Oral medications for chronic conditions often involve a variety of instructions, including time of day/dosing, drug interactions, and food intake restrictions. However, the extent to which patients follow these instructions is unclear. METHODS: We surveyed patients from the US and Europe (UK, France, Germany, Italy, Spain) who were prescribed sulfonylureas (SU: glimepiride, glipizide, or gliclazide) for diabetes or levothyroxine for hypothyroidism. Patients kept a daily diary for 3-5 days documenting their adherence to three criteria: dosing regimen including time of day, warning labels including drug interactions, and food restrictions. RESULTS: A total of 421 US and 493 European patients took the study medications; 546 patients took SU and 368 took levothyroxine. Overall, 48% of patients were males; 46% were age 65 years or older. Despite most patients having received instructions on medication requirements (US 71%, EU 75%), most patients reported being only somewhat knowledgeable (US 69%; EU 71%). Adherence, measured by the proportion of the days a participant was adherent to each category out of the observational period (ranging from 3-5 days), varied by type of instruction, with the poorest adherence observed for food restriction requirements (US 34% of the observation days, EU 26%) compared to warning labels (US 77%, EU 67%) and dosing regimen (US 85%, EU 87%). CONCLUSIONS: Patients adhered to dosing and cautionary instructions across the majority of the study period but were largely non-adherent to food intake restrictions. Improved communication and increased emphasis on food intake restrictions is needed when advising patients on their medications.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of DPP-4 inhibition with sitagliptin in youth with type 2 diabetes (T2D). STUDY DESIGN: This was a 54-week, double-blind, randomized, controlled clinical trial evaluating the safety and efficacy of DPP-4 inhibition with sitagliptin 100 mg once daily as initial oral therapy in youth with T2D. The 190 participants, aged 10-17 years, had HbA1c 6.5%-10% (7.0%-10% if on insulin). All were negative for pancreatic autoantibodies and overweight/obese at screening or diagnosis. The trial was placebo controlled for the first 20 weeks, after which metformin replaced placebo. The primary efficacy endpoint was change from baseline in HbA1c at Week 20. RESULTS: Treatment groups were well balanced at baseline (mean ± SD HbA1c = 7.5% ± 1.0, BMI percentile = 97.1% ± 6.8, age = 14.0 years ± 2.0 [57.4% <15], 60.5% female). At Week 20, least squares mean changes from baseline in HbA1c were -0.01% (sitagliptin) and 0.18% (placebo); between-group difference (95% CI) = -0.19% (-0.68, 0.30), p = 0.448. At Week 54, the changes in HbA1c were 0.45% (sitagliptin) and -0.11 (placebo/metformin). There were no notable between-group differences in the adverse event profiles through Week 54. CONCLUSIONS: DPP-4 inhibition with sitagliptin did not provide significant improvement in glycemic control. In this study, sitagliptin was generally well tolerated with a safety profile similar to that reported in adults. (ClinicalTrials.gov: NCT01485614; EudraCT: 2011-002528-42).

RESUMEN

OBJECTIVE: To assess the efficacy and safety of sitagliptin in youth with type 2 diabetes (T2D) inadequately controlled with metformin ± insulin. STUDY DESIGN: Data were pooled from two 54-week, double-blind, randomized, placebo-controlled studies of sitagliptin 100 mg daily or placebo added onto treatment of 10- to 17-year-old youth with T2D and inadequate glycemic control on metformin ± insulin. Participants (N = 220 randomized and treated) had HbA1c 6.5%-10% (7.0%-10% if on insulin), were overweight/obese at screening or diagnosis and negative for pancreatic autoantibodies. The primary endpoint was change from baseline in HbA1c at Week 20. RESULTS: Treatment groups were well balanced at baseline (mean HbA1c = 8.0%, BMI = 30.9 kg/m2 , age = 14.4 years [44.5% <15], 65.9% female). The dose of background metformin was >1500 mg/day for 71.8% of participants; 15.0% of participants were on insulin therapy. At Week 20, LS mean changes from baseline (95% CI) in HbA1c for sitagliptin/metformin and placebo/metformin were -0.58% (-0.94, -0.22) and -0.09% (-0.43, 0.26), respectively; difference = -0.49% (-0.90, -0.09), p = 0.018; at Week 54 the LS mean (95% CI) changes were 0.35% (-0.48, 1.19) and 0.73% (-0.08, 1.54), respectively. No meaningful differences between the adverse event profiles of the treatment groups emerged through Week 54. CONCLUSIONS: These results do not suggest that addition of sitagliptin to metformin provides durable improvement in glycemic control in youth with T2D. In this study, sitagliptin was generally well tolerated with a safety profile similar to that reported in adults. (ClinicalTrials.gov: NCT01472367, NCT01760447; EudraCT: 2011-002529-23/2014-003583-20, 2012-004035-23).

RESUMEN

AIMS: To assess the efficacy, safety and tolerability of ipragliflozin 50 mg once daily added to sitagliptin 50 mg once daily monotherapy in Japanese patients with type 2 diabetes (T2D). MATERIALS AND METHODS: The results of two clinical trials are reported. In both trials, patients had glycated haemoglobin (HbA1c) levels of 7.0% to 10.0% on sitagliptin 50 mg once daily 2 weeks prior to addition of ipragliflozin or placebo. In one trial (Trial 843), patients were randomized 1:1 to addition of blinded ipragliflozin 50 mg once daily (n = 73) or placebo (n = 70) for 24 weeks; the primary endpoint was efficacy (change in HbA1c at Week 24). In the other trial (Trial 849), open-label ipragliflozin 50 mg once daily was added for 52 weeks (n = 77); the primary objective was to assess safety/tolerability. RESULTS: In Trial 843, baseline characteristics were similar between groups (mean age 60.5 years, HbA1c 8.0%); after 24 weeks, adding ipragliflozin provided significantly greater reduction in HbA1c compared to placebo: least squares mean difference -0.77% (95% confidence interval -0.98, -0.57; P <0.001). In Trial 843, the incidences of adverse events (AEs) overall and prespecified AEs of clinical interest (symptomatic hypoglycaemia, urinary tract infection, genital infection, hypovolaemia, and polyuria/pollakiuria) were similar between groups. In Trial 849, specific AEs with incidence ≥5% were nasopharyngitis, pollakiuria, back pain, thirst, constipation, influenza and arthralgia; drug-related AEs reported in ≥2 patients were pollakiuria, thirst and constipation. CONCLUSIONS: Ipragliflozin 50 mg once daily added on to sitagliptin 50 mg once daily monotherapy provided significant improvement in glycaemic control and was generally well tolerated in Japanese patients with T2D.

RESUMEN

Objective: The objective of this study was to describe the pattern of comorbidities in patients with type 2 diabetes mellitus with and without atherosclerotic cardiovascular disease.Methods: This was a retrospective, cross-sectional analysis of the IQVIA Commercial Data Delivery database. Patients were ≥18 years on their last encounter between 1 October 2014 and 30 September 2015 and had either a type 2 diabetes mellitus diagnosis or a prescription for an oral diabetes medication. Atherosclerotic cardiovascular disease was confirmed by diagnosis codes. Comorbidities were identified using diagnosis codes, clinical measurements, and/or medication use.Results: A total of 1,522,526 type 2 diabetes mellitus patients were included in the analysis, 25% of whom had atherosclerotic cardiovascular disease. The most common comorbidities were hypertension, hyperlipidemia, overweight/obesity, chronic kidney disease, congestive heart failure, and neuropathy. These were present, respectively, in the following percentages of patients with and without cardiovascular disease: 98.3 and 91.0%, 94.8 and 78.5%, 80.5 and 80.6%, 38.5 and 18.9, 20.2, and 4.3%, and 13.7 and 8.6%. Thus, the frequencies of hyperlipidemia, chronic kidney disease, and congestive heart failure were notably higher in patients with cardiovascular disease. This trend held true for patients grouped by sex, age, and race.Conclusions: Patients with type 2 diabetes mellitus and atherosclerotic cardiovascular disease have different rates of certain comorbidities compared to those without atherosclerotic cardiovascular disease.

RESUMEN

AIMS: To investigate the efficacy, safety and tolerability of sitagliptin 50 mg once daily added to ipragliflozin 50 mg once daily monotherapy in Japanese patients with type 2 diabetes (T2D). MATERIALS AND METHODS: Japanese patients with T2D and glycated haemoglobin (HbA1c) 7.0% to 10.0% while treated with ipragliflozin 50 mg once daily were randomized 1:1 to additional treatment with sitagliptin 50 mg once daily (N = 70) or matching placebo (N = 71) for 24 weeks. The primary efficacy endpoint was change in HbA1c at Week 24. Secondary efficacy endpoints were changes in 2-hour post-meal glucose (PMG), total PMG 0- to 2-hour area under the curve (AUC0-2h ), and fasting plasma glucose (FPG). RESULTS: Baseline characteristics were similar in the two groups (mean age 55.5 years, mean baseline HbA1c 8.0%). After 24 weeks, the addition of sitagliptin provided significantly greater reduction in HbA1c compared to placebo (least squares [LS] mean difference -0.83% [95% confidence interval -1.05, -0.62]; P <0.001). Significant reductions were also observed in all secondary endpoints: LS mean differences from placebo in changes in 2-hour PMG, total PMG AUC0-2h , and FPG were -42.5 mg/dL, -67.0 mg·h/dL and -11.2 mg/dL, respectively (all P <0.001). The incidence of adverse events (AEs) overall and incidence of predefined AEs of clinical interest (symptomatic hypoglycaemia, urinary tract infection, genital infection, hypovolaemia and polyuria/pollakiuria) were similar in the two groups. CONCLUSIONS: In Japanese patients with T2D, sitagliptin 50 mg once daily added to ipragliflozin 50 mg once daily monotherapy provided significant improvement in glycaemic control and was generally well tolerated.

RESUMEN

AIM: To evaluate the efficacy and safety of adding the once-weekly oral dipeptidyl peptidase-4 inhibitor omarigliptin to treatment of Japanese patients with type 2 diabetes and inadequate glycaemic control on insulin monotherapy. MATERIALS AND METHODS: In a 52-week clinical trial, Japanese patients on insulin monotherapy were randomized to once-weekly omarigliptin 25 mg (N = 123) or placebo (N = 61) for a 16-week, double-blind, placebo-controlled period. After Week 16, patients continued or switched to omarigliptin for a 36-week open-label period. RESULTS: From a mean baseline of approximately 8.8%, the Week 16 least squares mean changes in HbA1c were -0.61% (omarigliptin) and 0.29% (placebo); the between-group difference was -0.90% (p < .001). At Week 52, the mean change from baseline in HbA1c was -0.57% in both the group on omarigliptin for 52 weeks and the group on omarigliptin for 36 weeks (switched from placebo at Week 16). During the first 16 weeks of treatment, the incidences of adverse events (AEs), serious AEs, drug-related AEs and discontinuation from trial medication because of an AE were similar in both groups. A slight increase in incidence of symptomatic hypoglycaemia was observed in the omarigliptin group (n = 13 [10.6%]) compared with placebo (n = 4 [6.6%]). No severe hypoglycaemia was reported during the study. No new safety signals emerged with treatment beyond Week 16 through Week 52. CONCLUSION: The addition of once-weekly omarigliptin to insulin therapy for up to 52 weeks was generally well tolerated and provided clinically meaningful improvement in glycaemic control throughout the trial period. ClinicalTrials.gov: NCT02906709.

RESUMEN

INTRODUCTION: Older patients with type 2 diabetes (T2D) are at increased risk of diabetic nephropathy and mild renal insufficiency. This analysis compared the anti-hyperglycemic efficacy and safety of sitagliptin with dapagliflozin in patients ≥ 65 years of age with T2D and mild renal insufficiency. METHODS: This was a post hoc analysis of data from 410 patients ≥ 65 years old who participated in a 24-week, randomized, double-blind clinical trial (CompoSIT-R [comparison of sitagliptin with dapagliflozin in mild renal impairment]; NCT02532855) in T2D patients with mild renal insufficiency and on metformin ± a sulfonylurea; the primary efficacy end point was change in HbA1c at week 24. RESULTS: Treatment groups were well balanced at baseline (mean HbA1c = 7.7/7.7% and eGFR = 79/76 ml/min/1.73 m2 for sitagliptin/dapagliflozin). At week 24, LS mean (95% CI) change in HbA1c and percentage of patients with HbA1c < 7% were greater with sitagliptin, - 0.48% and 41%, respectively, compared with dapagliflozin, - 0.36% and 28%; between-group differences = - 0.12% (- 0.36, 0.01) and 12.8% (3.3, 22.2) for change in HbA1c and percentage with HbA1c < 7%, respectively. The sitagliptin group had greater reductions in PPG end points, while the dapagliflozin group had greater reductions in FPG. Treatments were generally well tolerated. There were fewer drug-related adverse events (AEs) with sitagliptin than with dapagliflozin but AE profiles were otherwise similar. CONCLUSIONS: In patients ≥ 65 years of age with T2D and mild renal insufficiency with inadequate glycemic control on metformin ± sulfonylurea, treatment with sitagliptin for 24 weeks resulted in improvement in HbA1c relative to treatment with dapagliflozin that is consistent with that previously observed in the overall population. Both treatments were generally well tolerated.

RESUMEN

AIMS/INTRODUCTION: To assess the efficacy and safety of metformin/sitagliptin-based dual/triple therapy in elderly Chinese patients with type 2 diabetes mellitus. MATERIALS AND METHODS: This subgroup analysis included individuals aged ≥65 years from the STRATEGY study, a two-stage study in which type 2 diabetes mellitus patients with unsatisfactory glycemic control on metformin were first treated with the dual combination of metformin and sitagliptin for 16 weeks (n = 681), and then, if glycemic control had not been achieved, were treated with a third add-on oral antihyperglycemic drug for another 24 weeks (n = 291). The efficacy end-point was change in glycated hemoglobin (HbA1c) in each stage, and the safety end-point was adverse events with a focus on hypoglycemia. RESULTS: At week 16, the change in HbA1c was -0.81% from baseline, and the percentages of patients who achieved HbA1c targets of <7% and <7.5% were 44.9 and 67.2%, respectively. After 24 weeks, a further average HbA1c reduction of -0.60% was observed with specific reductions of -0.70% with glimepiride, -0.63% with gliclazide, -0.51% with repaglinide and -0.45% with acarbose. The proportions of patients who achieved HbA1c targets of <7% and <7.5% were 65.4 and 81.3%, respectively, over the entire study. The rates of drug-related adverse events and hypoglycemia were, respectively, 4.1 and 4.3% in the dual therapy stage, and 5.2% and 7.1% in the triple therapy stage, without occurrence of severe hypoglycemia. CONCLUSIONS: In elderly Chinese type 2 diabetes mellitus patients, metformin/sitagliptin-based dual and triple oral therapy can provide clinically meaningful glycemic control and is generally well tolerated with a low incidence of hypoglycemia.

RESUMEN

Objective: Hypoglycemia (HG) occurs in up to 60% of patients with diabetes mellitus (DM) each year. We assessed a HG alert tool in an electronic health record system, and determined its effect on clinical practice and outcomes.Methods: The tool applied a statistical model, yielding patient-specific information about HG risk. We randomized outpatient primary-care providers (PCPs) to see or not see the alerts. Patients were assigned to study group according to the first PCP seen during four months. We assessed prescriptions, testing, and HG. Variables were compared by multinomial, logistic, or linear model. ClinicalTrials.gov ID: NCT04177147 (registered on 22 November 2019).Results: Patients (N = 3350) visited 123 intervention PCPs; 3395 patients visited 220 control PCPs. Intervention PCPs were shown 18,645 alerts (mean of 152 per PCP). Patients' mean age was 55 years, with 61% female, 49% black, and 49% Medicaid recipients. Mean baseline A1c and body mass index were similar between groups. During follow-up, the number of A1c and glucose tests, and number of new, refilled, changed, or discontinued insulin prescriptions, were highest for patients with highest risk. Per 100 patients on average, the intervention group had fewer sulfonylurea refills (6 vs. 8; p < .05) and outpatient encounters (470 vs. 502; p < .05), though the change in encounters was not significant. Frequency of HG events was unchanged.Conclusions: Informing PCPs about risk of HG led to fewer sulfonylurea refills and visits. Longer-term studies are needed to assess potential for long-term benefits.

RESUMEN

AIMS/INTRODUCTION: To explore the factors associated with the glucose-lowering efficacy of sitagliptin treatment in Japanese patients with type 2 diabetes mellitus. MATERIALS AND METHODS: This was a post-hoc analysis of pooled data from seven sitagliptin phase II and III clinical studies carried out in Japan. All studies were double-blind, randomized, placebo-controlled, parallel-group and of 12-week duration. The analysis population consisted of 1,075 type 2 diabetes mellitus patients. In two of the trials, sitagliptin 50 mg and/or 100 mg daily were used as monotherapy; in five others, sitagliptin 50 mg daily was used as add-on treatment to ongoing pioglitazone, glimepiride, metformin, voglibose or glinides. Efficacy (reduction in hemoglobin A1c [HbA1c]) was evaluated in 12 sets of subgroups defined by demographic, glycemic, pancreatic ß-cell function and insulin resistance parameters. An analysis of covariance model was used to evaluate the interaction between each parameter and efficacy. RESULTS: Sitagliptin consistently provided a clinically meaningful reduction in HbA1c relative to placebo across all subgroups. Within subgroups, a greater absolute HbA1c reduction was associated with higher baseline HbA1c, fasting plasma glucose and 2-h post-meal glucose. Lower ß-cell function, represented by homeostatic model assessment of ß-cell function and insulinogenic index, was also associated with greater HbA1c reduction. In contrast, age, sex, body mass index, duration of type 2 diabetes mellitus and insulin resistance-related parameters did not interact with HbA1c changes. CONCLUSIONS: Sitagliptin treatment was associated with clinically meaningful improvement in glycemic control in all subgroups of Japanese patients with type 2 diabetes mellitus that were evaluated. Higher baseline glycemic status and lower baseline ß-cell function were identified as factors associated with greater HbA1c reduction after sitagliptin treatment.

RESUMEN

Objective: Hypoglycemia occurs in 20-60% of patients with diabetes mellitus. Identifying at-risk patients can facilitate interventions to lower risk. We sought to develop a hypoglycemia prediction model. Methods: In this retrospective cohort study, urban adults prescribed a diabetes drug between 2004 and 2013 were identified. Demographic and clinical data were extracted from an electronic medical record (EMR). Laboratory tests, diagnostic codes and natural language processing (NLP) identified hypoglycemia. We compared multiple logistic regression, classification and regression trees (CART), and random forest. Models were evaluated on an independent test set or through cross-validation. Results: The 38,780 patients had mean age 57 years; 56% were female, 40% African-American and 39% uninsured. Hypoglycemia occurred in 8128 (539 identified only by NLP). In logistic regression, factors positively associated with hypoglycemia included infection, non-long-acting insulin, dementia and recent hypoglycemia. Negatively associated factors included long-acting insulin plus sulfonylurea, and age 75 or older. The models' area under curve was similar (logistic regression, 89%; CART, 88%; random forest, 90%, with ten-fold cross-validation). Conclusions: NLP improved identification of hypoglycemia. Non-long-acting insulin was an important risk factor. Decreased risk with age may reflect treatment or diminished awareness of hypoglycemia. More complex models did not improve prediction.

RESUMEN

AIMS: TECOS was a randomized, double-blind, placebo-controlled trial assessing the impact of sitagliptin vs. placebo on cardiovascular outcomes when added to usual care in patients with type 2 diabetes. We report the use of concomitant diabetes medications and the risk for progression to insulin during follow-up. MATERIALS AND METHODS: TECOS enrolled 14 671 participants with HbA1c 6.5%-8.0% on monotherapy with metformin, pioglitazone, sulfonylurea (SU), or dual therapy with two oral agents or insulin with or without metformin. Subsequent diabetes management was by the participant's usual care physician. Time to initiation of insulin and risk of hypoglycaemia were estimated using Cox proportional hazards models. RESULTS: The most common glucose-lowering regimens at baseline were metformin monotherapy (30.2%), SU monotherapy (8.5%), metformin/SU therapy (35.1%), and insulin with or without metformin (13.9% and 8.6%, respectively). Over a median 3.0 years' follow-up, diabetes therapy was intensified in 25.2% of participants (sitagliptin 22.0%, placebo 28.3%). Medications most commonly added were SU (8.3%) or insulin (8.8%). Insulin initiation in the usual care setting occurred at mean (standard deviation) HbA1c of 8.5 (1.5)%. Sitagliptin did not impact rates of severe hypoglycaemia, but delayed progression to insulin when added to metformin or metformin/SU regimens. CONCLUSION: Consistent with the trial's pragmatic design, TECOS participants underwent typical progression of diabetes medications. Sitagliptin was associated with lower HbA1c, without increased risk for severe hypoglycaemia and was associated with delayed progression to insulin when added to metformin with or without SU.

RESUMEN

Objective: To assess the safety and efficacy of ertugliflozin over 104 weeks in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin. Methods: In this double-blind, multicenter, randomized, phase III study (VERTIS SU; NCT01999218), adults with T2DM and glycated hemoglobin (HbA1c) 7.0-9.0% on metformin ≥1500 mg/day received ertugliflozin 5 mg or 15 mg, or glimepiride. The primary efficacy time point was Week 52; double-blinded treatment continued until Week 104. Results: Baseline characteristics of randomized, treated patients (n = 1315) were similar across groups (mean age 58.2 years, HbA1c 7.8%); 76.4% completed the study; 61.6% completed on study medication. Mean glimepiride dose at 104 weeks was 3.5 mg/day. At Week 104, least squares mean change from baseline in HbA1c (95% confidence intervals) were -0.3% (-0.4, -0.2), -0.4% (-0.5, -0.3) and -0.4% (-0.5, -0.3) for ertugliflozin 5 mg, 15 mg, and glimepiride, respectively. Ertugliflozin provided sustained reductions in body weight and systolic blood pressure (SBP) over 104 weeks. The incidence of adverse events (AEs) and serious AEs was similar across groups. The incidence of symptomatic hypoglycemia was 3.8%, 6.4% and 22.1% in the ertugliflozin 5 mg, 15 mg, and glimepiride groups, respectively. Genital mycotic infections were reported in 5.3%, 2.6% and 0% of men, respectively, and 9.2%, 12.3% and 1.4% of women, respectively. The incidence of urinary tract infection and hypovolemia AEs was similar across groups. Conclusions: Ertugliflozin was well tolerated and provided clinically meaningful glycemic control and durable reductions in body weight and SBP over 104 weeks.
