RESUMEN
Importance: Despite rising costs and public scrutiny devoted to insulin, less is known regarding recent trends in its ambulatory use in the United States. Objective: To characterize trends in ambulatory insulin use, overall and based on insulin characteristics, among adults with type 2 diabetes in the United States from January 1, 2016, through December 31, 2020. Design, Setting, and Participants: This serial cross-sectional study included patients whose data were collected in IQVIA's National Disease and Therapeutic Index (NDTI), a 2-stage, all-payer, nationally representative audit of outpatient care. Approximately 4800 physicians each calendar quarter completed a form for 2 consecutive days regarding visits for each of their patients, including diagnoses, treatments, and demographic information. Data were collected from January 2016 through December 2020. Exposures: Ambulatory use of insulin. Main Outcomes and Measures: Nationally representative projections for ambulatory use of insulin (ie, treatment visits), overall and aggregated by insulin molecule (insulins regular, neutral protamine Hagedorn [NPH], lispro, glulisine, glargine, detemir, degludec, and aspart), delivery devices (vials/syringes or pens), therapeutic class (short-acting, rapid-acting, long-acting, intermediate-acting, and premixed insulin), insulin type (human, analog, and biosimilar), and date of approval (newer: before 2010; and older: after 2010). Results: There were 27â¯860â¯691 insulin treatment visits between 2016 and 2020. Among all patient encounters that indicated use of insulin in 2020, 1â¯989â¯154 (43.9%) were among those aged 60 to 74 years; 2â¯372â¯629 (52.4%) among men; 2â¯646â¯247 (58.4%) among White patients; 811â¯639 (17.9%) among Black patients; and 701â¯912 (15.5%) among Hispanic patients. Insulin glargine was the most frequently used insulin from 2016 to 2020, accounting for approximately half of treatment visits (eg, 2020: 2.6 of 4.9 million visits; 95% CI, 2.1-3.1 million). Among insulin classes, long-acting insulin accounted for approximately two-thirds of treatment visits during this period (eg, 2020: 3.7 million visits; 95% CI, 3.0-4.4 million). Treatment visits for insulin pens increased from 36.1% in 2016 (2.2 of 6.0 million visits; 95% CI, 1.7-2.7 million) to 58.7% in 2020 (2.9 million visits; 95% CI, 2.3-3.5 million), while use of insulin vials/syringes declined in parallel. Analog insulin use predominated and accounted for more than 80% of total treatment visits across all years (eg, 2020: 4.3 million visits; 95% CI, 3.4-5.1 million). Newer insulins were increasingly used, from 18.1% of total treatment visits in 2016 (1.1 million visits; 95% CI, 0.8-1.4 million) to 40.9% in 2020 (2.0 million visits; 95% CI, 1.5-2.5 million). The use of biosimilar insulin, which was first approved in 2015, increased from 2.6% in 2017 (0.1 of 5.3 million visits; 95% CI, 0.04-0.2 million) to 8.2% in 2020 (0.4 million visits; 95% CI, 0.2-0.6 million) of total insulin treatment visits. The total number of insulin treatment visits declined from a peak of 6.0 million visits in 2016 to a nadir of 4.9 million visits in 2020 (approximately 18% decline). Conclusions and Relevance: In this study, ambulatory insulin use in the United States during the past 5 years remained dominated by the use of insulin analogs and insulin pen delivery devices, with increasing uptake of newer products as they have been brought to market.

BACKGROUND: Available basal insulin regimes differ in pharmacokinetic profiles, which may be related to subsequent changes in anthropometry in patients with type 1 diabetes. This analysis elucidates the standardized height and body mass index development (height and BMI standard deviation score [height-SDS and BMI-SDS]) in pediatric type 1 diabetes patients depending on the choice of basal insulin. METHODS: Longitudinal data of 10 338 German/Austrian patients from the Diabetes Prospective Follow-up (DPV, Diabetes Patienten Verlaufsdokumentation) database were analyzed. Patients aged 5.0 to 16.9 years were treated exclusively with neutral protamine Hagedorn (NPH), insulin detemir (IDet), insulin glargine (IGla), or continuous subcutaneous insulin infusion (CSII) for at least 3 years. Population-based German reference data were used to calculate height-SDS and BMI-SDS. Multiple linear regression was conducted. RESULTS: BMI-SDS increased significantly in all regimes (NPH P = .0365; IDet P = .0003; IGla P < .0001; and CSII P < .0001). Direct comparison of the therapies revealed a favorable association only for NPH vs IGla. A rise in BMI-SDS was observed for all insulins in females, but only for IGla in males. BMI-SDS increment was not observed before 8 years of age. Initially and at the end of the observation period, mean height was above the 50th percentile of the reference population. Across the cohort, height-SDS declined during the observation period, except for CSII. Apart from the 5.0- to 7.9-year-old subgroup, long-acting insulin analogues were associated with a significant loss of height-SDS. CONCLUSIONS: Choice of basal insulin regimen might influence height development. CSII appeared to have a favorable effect on growth trajectories. All therapies were associated with an increase of BMI-SDS, most evident in females.

Hox and ParaHox genes encode transcription factors with similar expression patterns in divergent animals. The Pdx (Xlox) homeobox gene, for example, is expressed in a sharp spatial domain in the endodermal cell layer of the gut in chordates, echinoderms, annelids and molluscs. The significance of comparable gene expression patterns is unclear because it is not known if downstream transcriptional targets are also conserved. Here, we report evidence indicating that a classic transcriptional target of Pdx1 in vertebrates, the insulin gene, is a likely direct target of Pdx in Pacific oyster adults. We show that one insulin-related gene, cgILP, is co-expressed with cgPdx in oyster digestive tissue. Transcriptomic comparison suggests that this tissue plays a similar role to the vertebrate pancreas. Using ATAC-seq and ChIP, we identify an upstream regulatory element of the cgILP gene which shows binding interaction with cgPdx protein in oyster hepatopancreas and demonstrate, using a cell culture assay, that the oyster Pdx can act as a transcriptional activator through this site, possibly in synergy with NeuroD. These data argue that a classic homeodomain-target gene interaction dates back to the origin of Bilateria.

Insulin therapy has been a life saver for people with type 1 diabetes and has been an essential tool in the therapy of people with type 2 diabetes, but the risk for hypoglycaemia has been a major hurdle to achieving good glycaemic control for most. Insulin analogues, the availability of novel technologies for the administration of insulin, like insulin pumps, and, in particular, tools to measure glucose levels, evolving from capillary measurements to continuous glucose monitoring, have revolutionised the way in which people living with diabetes use insulin. Novel insulin concepts, like once-weekly or oral insulin administration, will have to demonstrate safety on the side of hypoglycaemia before they will be able to move into the clinic.

AIM: To ascertain the awareness and practice of neonatal diabetes mellitus (NDM) among paediatricians in Arab countries. METHODS: An online questionnaire was distributed to physicians associated with the Arab Society for Paediatric Endocrinology and Diabetes (ASPED). RESULTS: We received 126 replies, from 16 countries. All except one classified the survey's case scenario as NDM and 94% agreed that NDM patients should have detailed assessment to identify extra-pancreatic features. Although 92% felt that genetic testing is necessary, only 72% requesting them routinely and 32% unaware of the availability of free genetic testing. Insulin is considered the initial therapy for 93% and 80% diluted insulin to deliver accurate doses. Basal-bolus regimen was preferred by 36% and similar percentage used insulin pump. The remaining 28% favour long acting insulin alone. Oral sulfonylureas would be tried empirically by 34% and 69% would do so if genetic testing is unavailable. Whilst 70% have no local NDM management guidelines, 41% are unaware of any international guidelines. CONCLUSIONS: The ASPED surveyed clinicians have good awareness of NDM diagnosis with marked variation in their practice raising the need to establish management guideline for the condition. The survey highlights areas to focus on in developing consensus and educational activities.

El 80-90% de los pacientes atendidos en los servicios de urgencias son dados de alta desde los mismos, y por tanto los facultativos de urgencias son los responsables del tratamiento al alta en dichos pacientes. Se estima que la frecuencia de diabetes mellitus en urgencias es de un 30-40% y en muchos casos dicha diabetes está descompensada o con un mal control metabólico previo, por lo que es necesario establecer pautas de tratamiento antidiabético adecuadas de cara al alta que contribuyan a un adecuado control metabólico de dichos pacientes y favorezca un mejor pronóstico a corto plazo tras el alta, así como mantener una continuidad con la atención ambulatoria por parte de otras especialidades y contribuir a una mejoría del pronóstico a largo plazo. El presente documento es por tanto un consenso de expertos de tres sociedades científicas implicadas directamente en la atención del paciente diabético, que pretende facilitar la valoración del tratamiento al alta desde urgencias en cuanto a la diabetes se refiere y su continuidad asistencial ambulatoria (AU)
Eighty to 90% of patients attended in emergency departments are discharged to home. Emergency department physicians are therefore responsible for specifying how these patients are treated afterwards. An estimated 30% to 40% of emergency patients have diabetes mellitus that was often decompensated or poorly controlled prior to the emergency. It is therefore necessary to establish antidiabetic treatment protocols that contribute to adequate metabolic control for these patients in the interest of improving the short-term prognosis after discharge. The protocols should also maintain continuity of outpatient care from other specialists and contribute to improving the long-term prognosis. This consensus paper presents the consensus of experts from 3 medical associations whose members are directly involved with treating patients with diabetes. The aim of the paper is to facilitate the assessment of antidiabetic treatment when the patient is discharged from the emergency department and referred to outpatient care teams (AU)

Reasonable glycemic control is difficult to achieve in patients with diabetes mellitus (DM) receiving continuous enteral nutrition therapy (CENT). There are no solid evidence-based medicine guidelines regarding this issue in these patients. The purpose of this study was to determine if the use of a basal-bolus insulin regimen is more effective than neutral protamine Hagedorn (NPH) insulin alone in controlling blood glucose in non-critically ill patients with DM receiving CENT. We performed a retrospective, records-based review comparing basal-bolus with NPH insulin regimen in these patients, hospitalized in the internal medicine wards in our hospital. Number of hypoglycemic episodes, mean blood glucose, and time-to-target (time needed to reach 3 successive glucose readings in the appropriate target of 140-180 mg/dL) were evaluated in each regimen. Mean blood glucose was 199.22 mg/dL (95% confidence interval [CI], 179.8-218.5 mg/dL) in the basal-bolus vs 190.73 mg/dL (95% CI, 172.1-209.2 mg/dL) in the NPH insulin regimen ( P = .538). Time-to-target was an average of 3.65 ± 1.75 days in the basal-bolus group and 4.33 ± 2.42 days in the NPH group ( P = .364). There were no statistically significant differences in frequency of hypoglycemia ( P = .364). Rate of death was high (around 40%) in both groups. We conclude that hospitalized hyperglycemic patients receiving CENT can be treated by either basal-bolus or NPH insulin regimens. However, the overall glucose levels remain elevated during hospitalization irrespective of the insulin therapy. There is an urgent need to define glucose targets in this population of patients and to evaluate prospectively head-to-head different insulin protocols.

IMPORTANCE: Insulin is a vital medicine for patients with diabetes mellitus. Newer, more expensive insulin products and the lack of generic insulins in the United States have increased costs for patients and insurers. OBJECTIVE: To examine Medicaid payment trends for insulin products. Cost information is available for all 50 states and has been recorded since the 1990s. DESIGN, SETTING, AND PARTICIPANTS: A time-series analysis comparing reimbursements and prices. Using state- and national-level Medicaid data from 1991 to 2014, we identified all patients who used 1 or more of the 16 insulin products that were continuously available in the United States between 2006 and 2014. Insulin products were classified into rapid-acting and long-acting analogs, short-acting, intermediate, and premixed insulins based on American Diabetes Association Guidelines. MAIN OUTCOMES AND MEASURES: Inflation-adjusted payments made to pharmacies by Medicaid per 1 mL (100 IU) of insulin in 2014 US dollars. RESULTS: Since 1991, Medicaid reimbursement per unit (1 mL) of insulin dispensed has risen steadily. In the 1990s, Medicaid reimbursed pharmacies between $2.36 and $4.43 per unit. By 2014, reimbursement for short-acting insulins increased to $9.64 per unit; intermediate, $9.22; premixed, $14.79; and long-acting, $19.78. Medicaid reimbursement for rapid-acting insulin analogs rose to $19.81 per unit. The rate of increase in reimbursement was higher for insulins with patent protection ($0.20 per quarter) than without ($0.05 per quarter) (P<.001).Total Medicaid reimbursements peaked at $407.4 million dollars in quarter 2 of 2014. Total volume peaked at 29.9 million units in quarter 4 of 2005 and was 21.2 million units in quarter 2 of 2014. CONCLUSIONS AND RELEVANCE: Between 1991 and 2014, there was a near-exponential upward trend in Medicaid payments on a per-unit basis for a wide variety of insulin products regardless of formulation, duration of action, and whether the product was patented. Although reimbursements for newer, patent-protected insulin analogs increased at a faster rate than reimbursements for older insulins, payments increased for all products we examined. Our findings suggest a lack of price competition in the United States for this class of medications.

Insulin resistance syndromes without lipodystrophy are an infrequent and heterogeneous group of disorders with variable clinical phenotypes, associated with hyperglycemia and hyperinsulinemia. The three conditions related to mutations in the insulin receptor gene are leprechaunism or Donohue syndrome, Rabson-Mendenhall syndrome, and Type A syndrome. A case is presented on a patient diagnosed with type A insulin resistance, defined by the triad of extreme insulin resistance, acanthosis nigricans, and hyperandrogenism, carrying a heterozygous mutation in exon 19 of the insulin receptor gene coding for its tyrosine kinase domain that is crucial for the catalytic activity of the receptor. The molecular basis of the syndrome is reviewed, focusing on the structure-function relationships of the insulin receptor, knowing that the criteria for survival are linked to residual insulin receptor function. It is also pointed out that, although type A insulin resistance appears to represent a somewhat less severe condition, these patients have a high morbidity and their treatment is still unsatisfactory.

Insulin is an important endocrine hormone that plays a critical physiological role in regulating metabolism and glucostasis in vertebrates. In this study, the complete cDNA of Alligator sinensis preproinsulin gene was cloned for the first time by reverse transcription-polymerase chain reaction and rapid amplification of cDNA ends methods; the amino acid sequence encoded and protein structure were analyzed. The full-length of preproinsulin cDNA sequence consists of 528 base pairs (bp), comprising a 34-bp 5'-untranslated region, a 170-bp 3'-untranslated region and an open reading frame that is 324 bp in length. The open reading frame encodes a 107-amino acid preproinsulin with a molecular weight of approximately 12,153.8 Da, theoretical isoelectric point of 5.68, aliphatic index of 92.06, and grand average of hydropathicity of -0.157, from which a signal peptide, a B-chain, a C-peptide, and an A-chain are derived. Online analysis suggested that the deduced preproinsulin amino acid sequence contains a transmembrane region, and that it has a signal peptide whose cleavage site occurs between alanine 24 and alanine 25. Comparative analysis of preproinsulin amino acid sequences indicated that the A-chain and B-chain sequences of preproinsulins are highly conserved between reptiles and birds, and that the preproinsulin amino acid sequence of Alligator sinensis shares 89% similarity to that of Chelonia mydas, but low similarity of 48-63% to those of mammals and fishes. The phylogenetic tree constructed using the neighbor-joining method revealed that preproinsulin of Alligator sinensis had high homology with reptiles and birds, such as Chelonia mydas, Gallus gallus, and Columba livia.

The development of insulin analogs has made improved treatment of type 2 diabetes possible. In this article, structural alterations, pharmacokinetics and pharmacodynamics, clinical end points, and safety issues are reviewed for the currently available basal insulins, rapid-acting insulins, and premixes. The flatter activity profiles of insulin glargine and insulin detemir translate into good clinical efficacy with a lower risk of hypoglycemia relative to neutral protamine Hagedorn insulin. Weight gain is consistently lower with insulin detemir than with neutral protamine Hagedorn insulin. Insulin degludec, licensed in Europe and Japan but not yet in the United States, has a mean half-life of 25.4 hours, a duration of action of >42 hours, and low variability. In trials in type 2 diabetes, rates of nocturnal hypoglycemia were lower with insulin degludec than with insulin glargine, and more flexible; once-daily dose timing was shown to be possible. Insulin lispro, insulin aspart, and insulin glulisine are rapidly absorbed after injection and thus provide better coverage of the post-prandial glucose surge compared with human insulin. Trials and meta-analyses show that reductions in glycated hemoglobin are similar and control of postprandial glucose is better with the rapid-acting analogs versus human insulin. Convenience is greater for patients because the analogs can be injected just before a meal. In premix or biphasic insulins, a proportion of the rapid-acting analog is protaminated, providing both rapid-acting and intermediate-acting components in one formulation, thus reducing the number of injections required. Alterations to human insulin have resulted in improvements in safety, efficacy, tolerability, and convenience for patients.

INTRODUCTION: Hypoglycemia may have serious health consequences; therefore, it is important to expand knowledge on the factors that increase its prevalence. OBJECTIVES: The aim of the study was to evaluate the effect of the type of insulin-human vs. analogue-on the incidence of mild and severe hypoglycemia, body weight, and hemoglobin A1c (HbA1c) levels. PATIENTS AND METHODS: A total of 203 diabetic patients treated with intensive insulin therapy completed the questionnaire on hypoglycemia at baseline and at 3 and 6 months of the followup. Body weight and HbA1c levels were measured at baseline and at 6 months. Incidence of mild and severe hypoglycemia, body weight, and HbA1c levels were compared between patients treated with shortacting analogue and those treated with shortacting human insulin (regardless of the type of longacting insulin used) and between patients receiving short- and longacting analogue insulin and those receiving short- and longacting human insulin. A multiple logistic regression analysis was used to find independent risk factors of severe hypoglycemia. RESULTS: At baseline, mild hypoglycemia was more common in patients receiving insulin analogue. There were no differences between the subgroups in the incidence of severe hypoglycemia, HbA1c levels, and body weight. Male sex, older age, and the dose of longacting insulin were independently associated with a higher incidence of severe hypoglycemia. Type 2 diabetes and higher body weight were associated with a lower risk of severe hypoglycemia. CONCLUSIONS: Our results suggest that use of insulin analogues may predispose to more frequent episodes of mild hypoglycemia, but it does not increase the incidence of severe hypoglycemia in patients on intensive insulin therapy. Insulin analogues are not different from human insulin in terms of the effects on HbA1c levels and body mass.

BACKGROUND: Through a retrospective database analysis, this study seeks to provide an understanding of the utilization of SMBG by insulin therapy and diabetes type and to estimate healthcare costs of blood glucose monitoring in the UK diabetes population. METHODS: Data were obtained from the IMS LifeLink Electronic Medical Record-Europe (EMR-EU) Database, a longitudinal database containing anonymized patient records from physician-practice data systems of office-based physicians in the UK. Depending on the insulin types used for type 1 and type 2 diabetes, patients were sub-categorized into one of four insulin regimen groups (basal, bolus, pre-mixed, or basal-bolus). Frequency of blood glucose testing was assessed descriptively throughout the 12-month post-index period, and generalized linear models were used to evaluate the effect of baseline characteristics, including insulin type, on the likelihood of blood glucose test utilization. Healthcare resource utilization and costs for all-cause services were assessed by insulin type. RESULTS: This study identified 8322 type 1 and type 2 diabetes patients with two insulin pharmacy records between January 1, 2009 and December 31, 2010. After applying study inclusion and exclusion criteria, a total of 2676 (32.2%) insulin-treated diabetes mellitus patients in the UK were identified, with the number of pharmacy blood glucose test strips averaging 771.1 (median 600). The glucose testing frequency was lowest among basal-only insulin patients and pre-mixed insulin patients (mean=576.2 [median=450] and mean=599.5 [median=500], respectively; non-significantly different) compared to other insulin types. CONCLUSION: Although the data did not capture the glucose frequency comprehensively, it varied significantly by insulin types, and was higher than what is recommended in the guidelines for patients with type 2 diabetes.

AIMS: To evaluate the risk from different insulin types on severe hypoglycaemia (SHG) events requiring inpatient (IP) or emergency department (ED) care in patients with type 2 diabetes. METHODS: Type 2 diabetes patients newly started on insulin in a large commercial claims database were evaluated for SHG events. Patients were classified into an insulin group based on their most frequently used insulin type. Multivariable Cox models assessed the association between insulin type and the risk of SHG events. RESULTS: We identified 8626 patients (mean age 53.5 years; 55% female) with type 2 diabetes followed for an average of 4.0 years after insulin initiation. Of these, 161 (1.9%) had a SHG event at an average of 3.1y after insulin initiation. Patients with SHG events were slightly older (56.4 vs. 53.4 years), used a similar number of OADs (1.1 vs. 1.2) but had more co-morbidities compared with those without SHG events. In multivariate Cox models, premixed insulin (HR 2.12; p<0.01), isophane insulin (NPH) (HR 2.02; p<0.01), and rapid acting insulin (HR 2.75; p<0.01) had significantly higher risks of SHG events compared with glargine. No statistically significant difference in SHG events was seen with detemir (HR 1.20; p=0.73). CONCLUSIONS: Among patients with type 2 diabetes, the use of newer basal insulin analogues was associated with lower rates of SHG events requiring IP or ED care compared with users of other insulin formulations. Future research should examine the impact of hypoglycaemia events of different severity levels.

The grand dame of diabetes pharmacotherapy, nearly a century old, insulin continues to be the subject of discovery and innovation. Fresh research, combined with extensive clinical experience, has brought newer facets of insulin use to the fore. Thus, insulin still exudes maiden charm. This review covers recent advances in the clinical pharmacology of insulin.

OBJECTIVE: To assess the estimated glucose disposal rate (eGDR), insulin dose, and lipoprotein profile in children with type 1 diabetes mellitus (T1DM) and overweight or obesity as compared to children with T1DM and normal weight. METHODS: A total of 115 patients (aged 5-16 years) with T1DM on intensive insulin therapy were recruited. The following parameters were measured: weight, height, body mass index, waist and hip circumference, insulin dose, eGDR, glycosylated hemoglobin, blood pressure, and lipoprotein profile. Results were stratified by sex and age. RESULTS: No significant differences were found in eGDR between children with normal weight, overweight, and obesity. However, obese children older than 11 years had lower eGDR values (9.3±1.3 vs 10.1±0.8 mg kg(-1)min(-1); p<0.01). Insulin dose was higher in overweight and obese children, especially in IU/m2/day (37.7 vs 36.1 vs. 29.4 respectively; p<0.01). Obese children had higher low-density lipoprotein cholesterol levels than children with overweight and normal weight (106.5 vs 91.7 vs 91.5mg/dL respectively; p<0.01). No correlation was found between waist circumference and the different markers of insulin resistance. CONCLUSIONS: Values of eGDR values were lower in obese children with T1DM older than 11 years, and this may therefore be considered a marker of insulin resistance. Insulin dose was higher in diabetic patients with overweight or obesity, specially in IU/m2/day. Obese children with T1DM had a lipoprotein profile of cardiovascular risk.
