Italian guidelines for the treatment of type 2 diabetes

Effectiveness, Simplification and Persistence of IDegLira in Poorly Controlled People with Type 2 Diabetes: A 4-Year Follow-Up Real-World Study

INTRODUCTION

Efficacy and safety of the fixed ratio combination of insulin degludec and liraglutide (IDegLira) has been largely documented. However, long-term data are limited. This study aimed at describing persistence in therapy and the effectiveness at 48 months of IDegLira.

METHODS

We conducted an observational study based on retrospective chart review. All patients treated with IDegLira during 2018-2022 were included. Data on treatment approaches and clinical outcomes were collected at the first prescription of IDegLira (T0) and after 6, 12, 24, 36, and 48 months.

RESULTS

Overall, 156 patients (mean age 68 years, 64.1% men) started IDegLira, of whom 88 (56.4%) were previously treated with basal-oral therapy (BOT) and 68 (43.6%) with basal-bolus schemes (BB). Before starting IDegLira, 23.8% were treated with ≥ 2 oral antihyperglycemic agents in association with insulin; at T0, the proportion decreased to 3.2%. Short-acting insulin was discontinued after the first week. After 48 months, levels of HbA1c were significantly reduced by 1.34% in the BOT group and 1.07% in the BB group (p < 0.0001 in both groups). In the BOT group, FBG levels decreased by about 50 mg/dl and body weight was unchanged. In the BB group, FBG levels decreased by about 40 mg/dl and body weight was significantly reduced by an average of 7.7 kg. Five patients (3.2%) interrupted therapy with IDegLira during 48 months, and no severe hypoglycemia occurred.

CONCLUSIONS

Our study emphasizes the important role of IDegLira in maintaining a good metabolic control while minimizing the risk of major hypoglycemia and weight gain in the long term. The substantial simplification of treatment schemes can increase adherence.

Use of IDegLira to Intensify, Simplify, and Increase Appropriateness of Type 2 Diabetes Therapy: A Real-Life Experience

INTRODUCTION

Fixed ratio combination of insulin degludec and liraglutide (IDegLira) represents an option to revise inappropriate therapies in patients with poorly controlled type 2 diabetes. This study aimed to assess the pattern of use and 1-year effectiveness of IDegLira.

METHODS

A retrospective chart review was performed to assess changes in glycated hemoglobin (HbA1c) (primary endpoint), fasting blood glucose (FBG), body weight, estimated glomerular filtration rate (eGFR), and lipid profile following IDegLira initiation. Previous versus concomitant diabetes treatments were also compared.

RESULTS

Overall, 87 patients (mean age 73.9 ± 9.2 years, diabetes duration 18.2 ± 6.7 years, 62.1% men, HbA1c 8.3 ± 1.3%, BMI 30.4 ± 5.5 kg/m2) initiated IDegLira. Previously, 21.8% of patients were treated with oral hypoglycemic agents (OHA group), 47.1% with basal insulin ± OHA (BOT group), 5.8% with GLP-1 RA ± basal insulin (GLP1-RA group), and 25.3% with basal-bolus schemes (BB group). At the first prescription of IDegLira, secretagogues and schemes including two or more OHA were substantially reduced, leaving metformin as the most prevalent OHA (81.6%) used in combination with IDegLira. Starting dose of IDegLira ranged from 18.7 ± 3.1 U (OHA group) to 24.1 ± 4.4 U (BB group). After 1 year, HbA1c was significantly reduced by 1.25% (95% CI - 1.48; - 1.03), FBG by 52.9 mg/dl, and body weight by 2.0 kg. Also, eGFR levels and lipid profile significantly improved. No severe hypoglycemia occurred.

CONCLUSION

It is possible to proactively review suboptimal or inappropriate diabetes treatment according to the most recent guidelines. Results suggest that initiation of IDegLira was associated with a reduction in drugs to be administered daily and relevant improvements in clinical outcomes.

Clinical Features, Cardiovascular Risk Profile, and Therapeutic Trajectories of Patients with Type 2 Diabetes Candidate for Oral Semaglutide Therapy in the Italian Specialist Care

INTRODUCTION

This study aimed to address therapeutic inertia in the management of type 2 diabetes (T2D) by investigating the potential of early treatment with oral semaglutide.

METHODS

A cross-sectional survey was conducted between October 2021 and April 2022 among specialists treating individuals with T2D. A scientific committee designed a data collection form covering demographics, cardiovascular risk, glucose control metrics, ongoing therapies, and physician judgments on treatment appropriateness. Participants completed anonymous patient questionnaires reflecting routine clinical encounters. The preferred therapeutic regimen for each patient was also identified.

RESULTS

The analysis was conducted on 4449 patients initiating oral semaglutide. The population had a relatively short disease duration (42% < 5 years), and a minority (15.6%) had a history of cardiovascular events. Importantly, oral semaglutide was started in subjects with various disease durations and background therapies. Notably, its initiation was accompanied by de-prescription of sulfonylureas, pioglitazone, DPP-4 inhibitors, and insulin. Choice of oral semaglutide was influenced by patient profiles and ongoing glucose-lowering regimens. Factors such as younger age, higher HbA1c, and ongoing SGLT-2 inhibitor therapy drove the choice of oral semaglutide with the aim of improving glycemic control. Projected glycemic effectiveness analysis revealed that oral semaglutide could potentially lead HbA1c to target in > 60% of patients, and more often than sitagliptin or empagliflozin.

CONCLUSION

The study supports the potential of early implementation of oral semaglutide as a strategy to overcome therapeutic inertia and enhance T2D management.

Drug-induced hypoglycemia: a disproportionality analysis of the FAERS database

BACKGROUND

Hypoglycemia is an adverse event (AE) that cannot be ignored in clinical practice. This study aimed to identify the most common and top drugs associated with the risk of hypoglycemia based on the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database.

RESEARCH DESIGN AND METHODS

We used OpenVigil 2.1 pharmacovigilance analytics platform to query FAERS database and data from 2004 to 2023 were retrieved. The Medical Dictionary for Regulatory Activities (MedDRA) was used to identify hypoglycemia cases, and DrugBank database was used to determine drug generic names.

RESULTS

A total of 11,155,106 AEs reports were identified, of which 28,443 (0.25%) were related to hypoglycemia. Metformin (6926 cases) was associated with most cases of hypoglycemia. According to the disproportionality analysis, the top five drugs with the highest ROR and PRR were penamecillin, nikethamide, sotagliflozin, norethandrolone, glimepiride/pioglitazone. Nineteen of the top 50 drugs did not have hypoglycemia indicated in the package insert.

CONCLUSIONS

By analyzing the FAERS database, we listed drugs with a strong hypoglycemic signal for which the label does not provide a reminder. Notably, the potential hypoglycemia risks are of great importance and should be closely monitored in medical practice.

Real-World Retrospective Study into the Effects of Oral Semaglutide (As a Switchover or Add-On Therapy) in Type 2 Diabetes

(1) Background: Oral semaglutide represents the first oral GLP-1 RA approved for the treatment of type 2 diabetes mellitus (T2DM). This real-world retrospective study aimed at evaluating its effectiveness and tolerability in the treatment of patients with T2DM when patients switched from a glucose-lowering agent to it and when it was added to the usual therapy. (2) Methods: Adult patients with T2DM taking oral semaglutide and followed in the ASUGI Diabetes Center were identified with the use of electronic medical records between October 2022 and May 2023. (3) Results: A total of 129 patients were recruited. The median follow-up was 6 months. Be it as a switchover or as an add-on therapy, oral semaglutide significantly reduced HbA1c and BMI. Switching from DPPIV inhibitors to oral semaglutide was associated with a significant reduction in HbA1c and BMI, switching from SGLT2 inhibitors was associated with a significant reduction in HbA1c, and switching from sulphonylureas was associated with a significant reduction in BMI. The median HbA1c change was associated with baseline HbA1c. SBP significantly decreased in the add-on group. Oral semaglutide was well tolerated. (4) Conclusions: This study shows that in the real-world setting, oral semaglutide is effective and safe as a switchover or as an add-on therapy for the treatment of T2DM.

Once-weekly semaglutide use in patients with type 2 diabetes: Real-world data from the SURE Italy observational study

AIMS

SURE Italy, a multicentre, prospective, open-label, observational, real-world study, investigated once-weekly semaglutide in patients with type 2 diabetes (T2D) in routine clinical practice.

MATERIALS AND METHODS

Adults with T2D and ≥1 documented glycated haemoglobin (HbA1c) level within 12 weeks of semaglutide initiation were enrolled. The primary endpoint was change in HbA1c from baseline to end of study (EOS; ~30 weeks). Other endpoints included changes in body weight, waist circumference and patient-reported outcomes, and the proportion of patients achieving HbA1c <7.0% or <6.5%, weight loss ≥5% and a post-hoc composite endpoint (HbA1c reduction of ≥1%-point and weight loss ≥5%). These endpoints were reported for patients on semaglutide at EOS [effectiveness analysis set (EAS)]. Safety data were reported in the full analysis set.

RESULTS

Of 579 patients who initiated semaglutide (full analysis set), 491 completed the study on treatment (EAS). Mean baseline HbA1c was 8.0%, and 20.7% (120 of 579) of patients had HbA1c <7.0%. Mean semaglutide dose at EOS was 0.66 ± 0.28 mg. In the EAS, mean HbA1c and body weight decreased by 1.1%-point (95% confidence interval 1.20, 1.05; P < .0001) and 4.2 kg (95% confidence interval 4.63, 3.67; P < .0001), respectively. At EOS, 61.7% and 40.8% of patients achieved HbA1c <7.0% and <6.5%, respectively, 40.5% achieved weight loss ≥5% and 25.3% achieved the post-hoc composite endpoint. Patient-reported outcomes improved from baseline to EOS. No new safety concerns were identified.

CONCLUSIONS

In routine clinical practice in Italy, patients with T2D treated with once-weekly semaglutide for 30 weeks achieved clinically significant improvements in HbA1c, body weight and other outcomes.

Italian Guidelines for the Management of Non-Functioning Benign and Locally Symptomatic Thyroid Nodules

AIM

This guideline (GL) is aimed at providing a reference for the management of non-functioning, benign thyroid nodules causing local symptoms in adults outside of pregnancy.

METHODS

This GL has been developed following the methods described in the Manual of the National Guideline System. For each question, the panel appointed by Associazione Medici Endocrinology (AME) identified potentially relevant outcomes, which were then rated for their impact on therapeutic choices. Only outcomes classified as "critical" and "important" were considered in the systematic review of evidence and only those classified as "critical" were considered in the formulation of recommendations.

RESULTS

The present GL contains recommendations about the respective roles of surgery and minimally invasive treatments for the management of benign symptomatic thyroid nodules. We suggest hemithyroidectomy plus isthmectomy as the first-choice surgical treatment, provided that clinically significant disease is not present in the contralateral thyroid lobe. Total thyroidectomy should be considered for patients with clinically significant disease in the contralateral thyroid lobe. We suggest considering thermo-ablation as an alternative option to surgery for patients with a symptomatic, solid, benign, single, or dominant thyroid nodule. These recommendations apply to outpatients, either in primary care or when referred to specialists.

CONCLUSION

The present GL is directed to endocrinologists, surgeons, and interventional radiologists working in hospitals, in territorial services, or private practice, general practitioners, and patients. The available data suggest that the implementation of this GL recommendations will result in the progressive reduction of surgical procedures for benign thyroid nodular disease, with a decreased number of admissions to surgical departments for non-malignant conditions and more rapid access to patients with thyroid cancer. Importantly, a reduction of indirect costs due to long-term replacement therapy and the management of surgical complications may also be speculated.

Development of the Italian Clinical Practice Guidelines on Bariatric and Metabolic Surgery: Design and Methodological Aspects

Development of the Italian clinical practice guidelines on bariatric and metabolic surgery, as well as design and methodological aspects.

BACKGROUND

Obesity and its complications are a growing problem in many countries. Italian Society of Bariatric and Metabolic Surgery for Obesity (Società Italiana di Chirurgia dell'Obesità e delle Malattie Metaboliche-SICOB) developed the first Italian guidelines for the treatment of obesity.

METHODS

The creation of SICOB Guidelines is based on an extended work made by a panel of 24 members and a coordinator. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology has been used to decide the aims, reference population, and target health professionals. Clinical questions have been created using the PICO (Patient, Intervention, Comparison, Outcome) conceptual framework. The definition of questions used the two-step web-based Delphi method, made by repeated rounds of questionnaires and a consensus opinion from the panel.

RESULTS

The panel proposed 37 questions. A consensus was immediately reached for 33 (89.2%), with 31 approved, two rejected and three which did not reach an immediate consensus. The further discussion allowed a consensus with one approved and two rejected.

CONCLUSIONS

The areas covered by the clinical questions included indications of metabolic/bariatric surgery, types of surgery, and surgical management. The choice of a surgical or a non-surgical approach has been debated for the determination of the therapeutic strategy and the correct indications.

Pharmacological Treatment of Type-2-Diabetes and Cardiovascular Comorbidities: Differences between Undocumented Migrants and Natives in Italy

Diabetes prevalence is growing worldwide, especially in some populations. Though migrations seem to contribute to the presence in host countries of a significant number of patients with diabetes and its comorbidities, very little is known about the health conditions of undocumented migrants. We retrospectively studied 838 patients with type 2 diabetes mellitus (T2DM), 425 Italians followed by the diabetes clinic of a university hospital, and 413 undocumented migrants receiving assistance from a non-governmental organization. We analyzed their demographic and clinical data together with the medications they were on. The prevalence of the use of specific classes of drugs was compared between undocumented migrants and Italians by fitting a Poisson regression model, and the results were reported as prevalence rate ratios (PRRs) with a 95% confidence interval. Undocumented migrants with T2DM received fewer medications for cardiovascular (CV) conditions (PRR: 0.68, 0.60 to 0.76) than Italians, after correcting for confounding factors. Only sulfonylureas were more frequently used in undocumented migrants. The causes of these differences are not completely clear, but social, cultural, and economic factors can have an important role. More efforts are needed to provide appropriate treatment of diabetes and its CV comorbidities to undocumented migrants.

Real world effectiveness of subcutaneous semaglutide in type 2 diabetes: A retrospective, cohort study (Sema-MiDiab01)

INTRODUCTION

Aim of the present study was to evaluate the real-world impact of once-weekly (OW) subcutaneous semaglutide on different end-points indicative of metabolic control, cardiovascular risk factors, and beta-cell function in type 2 diabetes (T2D).

METHODS

This was a retrospective, observational study conducted in 5 diabetes clinics in Italy. Changes in HbA1c, fasting blood glucose (FBG), body weight, blood pressure, lipid profile, renal function, and beta-cell function (HOMA-B) during 12 months were evaluated.

RESULTS

Overall, 594 patients (97% GLP-1RA naïve) were identified (mean age 63.9 ± 9.5 years, 58.7% men, diabetes duration 11.4 ± 8.0 years). After 6 months of treatment with OW semaglutide, HbA1c levels were reduced by 0.90%, FBG by 26 mg/dl, and body weight by 3.43 kg. Systolic blood pressure, total and LDL-cholesterol significantly improved. Benefits were sustained at 12 months. Renal safety was documented. HOMA-B increased from 40.2% to 57.8% after 6 months (p<0.0001).

DISCUSSION

The study highlighted benefits of semaglutide on metabolic control, multiple CV risk factors, and renal safety in the real-world. Semaglutide seems to be an advisable option for preservation of β-cell function and early evidence suggests it might have a role in modifying insulin resistance (HOMA-IR), the pathogenetic basis of prediabetes and T2D.
