Patients in insulin analogues use via judicial litigation: do they use the Brazilian Public Health System (SUS)? / Pacientes em uso de análogos de insulina via ação judicial: eles utilizam o Sistema Único de Saúde (SUS)?

Abstract Background Studies show that among the drugs most commonly used in judicial litigation in Brazil, are those used to treat diabetes mellitus, especially insulin analogues. Objective Evaluate the use of the Unified Health System (SUS) by patients with type 1 diabetes mellitus (T1DM), who receive insulin analogues through judicial action, before and after this process. Method In a retrospective longitudinal observational study, secondary data was used from these patients in Minas Gerais, Brazil, in 2018. Socio-demographic information was collected and related to the follow-up of these patients in the SUS. The McNemar χ2 test was used to compare the proportions of the variables. Results Of the 89 patients analyzed, women (53.9%) were predominant. Most patients were aged between 20 and 39 years (52.8%), and more than half, 55.1%, use only a private health system. After the judicial action, there was a significant increase (p <0.05) in the number of patients who had consultations in primary health care (from 19.1% to 30.3%) and emergency medical appointments (from 1.1% to 9.0%). Conclusion It is observed that the majority of patients with T1DM via judicial action in the SUS are not monitored by this health system through examinations, consultations, and hospitalizations.

Introduction: Insulin is an important drug that can be used for providing treatment to the patient with type 2 diabetes mellitus. Objective: To describe some of the characteristics of insulin treatment in patients with type 2 diabetes mellitus. Methods: The necessary information for writing this article was obtained in the trimester October-December 2020. As search engines for scientific information, Google Scholar, Pubmed and SciELO were used. Different review papers, research papers and web pages were assessed, generally less than ten years old and published in Spanish, Portuguese or English. The following keywords were used: tratamiento [treatment], insulina [insulin]; análogos de insulina [insulin analogues], diabetes mellitus. The articles not meet the above conditions were excluded. This allowed the study of eighty articles, of which 43 were referenced. Conclusions: Insulin is a polypeptide hormone synthesized by the β cells of the islets of Langerhans of the pancreas. Its effect is produced primarily at the liver, adipose tissue and muscle levels. It is a therapeutic option in any evolutionary phase of type 2 diabetes mellitus, when oral agents fail to achieve goals or if certain complications occur. A wide range of insulin types with different action and concentration profiles are available, allowing them to be classified in different ways. Different criteria have been established about when to start and how to guide insulin treatment in the person with type 2 diabetes mellitus, making better glycemic control possible.

Hypoglycemia frequency and treatment satisfaction in patients receiving insulin analogues for treatment of type 1 diabetes mellitus

ABSTRACT Objective: The aim of this study was to evaluate the frequency of hypoglycemia and the treatment satisfaction in patients with type 1 diabetes (T1D) using insulin analogues. Subjects and methods: This observational retrospective study included 516 adult patients with T1D from 38 cities in Southern Brazil. Demographics and clinical data were collected using a self-report questionnaire. Hypoglycemia was defined as an event based on either symptoms or self-monitored blood glucose < 70 mg/dL. Treatment satisfaction was evaluated using the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and with a specific question with scores ranging from 0-10. Common mental disorders were assessed using the General Health Questionnaire (GHQ-12). Results: Overall, the mean age was 38 ± 14 years and 52% of the participants were women. The median diabetes duration was 18 years. The scores for insulin analogue treatment satisfaction were higher than those for previous treatments. DTSQ scores had a median value of 32 (interquartile range 29-35) and remained unchanged over time. The percentage of patients with hypoglycemia (including severe and nocturnal) was comparable across groups divided according to duration of use of insulin analogues. Most patients (n=395, 77%) screened positive for common mental disorders. Conclusions: Patient satisfaction with insulin analogue treatment was high and remained unchanged with time. Episodes of hypoglycemia also remained unchanged over time among patients using insulin analogues.

Cost-effectiveness Analysis of Insulin Analogues and Human Insulin in the Treatment of Type 2 Diabetes Mellitus Based on Net-benefit Regression Framework / 中国药房

OBJECTIVE：To compare the cost-effectiveness of insulin analogues and human insulin in the treatment of type 2 diabetes mellitus ，to reduce economic burden of patients ，and to provide new ideas for non-randomized pharmacoeconomic research. METHODS ：Retrospective data of a Third-grade Class-A hospital were adopted and 533 patients with type 2 diabetes were taken as object to balance the difference between groups through propensity score matching ，and construct net-benefit regression framework so as to analyze the cost-effectiveness of insulin analogues and human insulin in the treatment of type 2 diabetes mellitus. RESULTS ：There was a positive relationship between the efficacy and cost of the two therapeutic schemes ，i.e. insulin analogues were more effective than human insulin ，and the difference of total effective rate between the two schemes was 14.5％. The corresponding treatment cost of insulin analogues was higher than that of human insulin ，and the average total cost difference was 960.3 yuan. The cost of insulin analogues was 66.23 yuan more than that of human insulin for each additional unit of clinical effect （total effective rate ）. Results of net-benefit regression analysis showed that critical value of willingness to pay of therapy plan was 16 947.5 yuan. CONCLUSIONS ：When the willingness to pay is more than 16 947.5 yuan，the insulin analogue scheme is suitable ；on the contrary ，the human insulin analogue scheme is suitable. The propensity scoring technology used for the net-benefit regression analysis can broaden the source of avaliable data for non-randomized pharmacoeconomic evaluation.

Clinical practice of low-and mid-mixtures insulin analogues in patients with type 2 diabetes mellitus / 中华内分泌代谢杂志

Premixed insulin is currently the most popular insulin starter in China.According to the different ratios of basal and prandial components,premixed insulin analogues could be classified into low-and midmixtures.The former is now mainly used as insulin starter in the patients with type 2 diabetes mellitus after the failure of monotherapy or combination with oral antidiabetic drugs,while the later is usually used as simplified intensive insulin treatment in patients with type 2 diabetes mellitus inadequately controlled on insulin once-or twice-daily.

Unusually Elevated Serum Insulin Level in a Diabetic Patient during Recombinant Insulin Therapy

Herein, we report a case of unusually elevated serum insulin level as a result of increased anti-insulin antibody (IA)-bound insulin after continuous subcutaneous insulin infusion therapy. Detecting free insulin (unbound IAs) levels after polyethylene glycol pre-treatment could be useful to assess functional insulin levels in diabetic patients receiving insulin therapy. The E170 insulin assay can estimate total insulin (bound IAs and free insulin) levels, but it does not measure the levels of exogenous insulin analogues.

Perspective of biosimilars: A brief comment on immunogenicity of human insulin biosimilars based on viewing of severe adverse events of epoetin α and roferon A / 中华内分泌代谢杂志

A number of biosimilars will be soon marketing due to the expiration of patent protection of their originators.Unlike classical chemical drugs,biotherapeutics are proteins with large and complex molecules produced by biological high-tech with sophisticated manufactural procedures.This leads to the difficulties of the copy of biosimilars from their originators,and the almost inevitable distinctions between the two products.Thus biosimilars are only similar but not identical to their reference drugs in terms of stracture,action,and safety.It is important for physicians to understand these differences before using biosimilars.Optimal management by a national regulatory authority with rigorous standards is very important in all aspects of authorization of the development,production,marketing,and postmarketing surveillances for biosimilars.

Uso de los análogos de la insulina durante el embarazo

Los análogos de la insulina se han usado en el tratamiento de la diabetes asociada al embarazo, aún sin la aprobación de instancias reguladoras. Con el fin de conocer su eficacia y seguridad materno-fetal, se realizó la revisión bibliográfica sobre el tema. En cuanto a la Glulisina, no hay reporte de su uso en la gestación. Con Lispro, hay pocos estudios aleatorios donde se compare su uso con insulina humana regular, pero hay variados estudios observacionales en su mayoría retrospectivos, que no revelan aumento de riesgo. Referente a Aspart, se ha investigado en mujeres con diabetes tipo 1 durante el embarazo mediante un ensayo clínico aleatorio controlado, donde se compara con insulina humana regular, cuyos resultados sirvieron de base para la aprobación de su uso en gestantes. Con Glargina, se han llevado a cabo estudios observacionales, pero no aleatorios controlados y con Detemir, se finalizó el año 2011 un estudio aleatorio controlado, comparando con insulina humana NPH, cuyos resultados sustentaron la reciente aprobación por la Federal Drug Administration para su uso en embarazadas. En conclusión, Lispro y Aspart constituyen las opciones de análogos de acción rápida a usar durante el embarazo cuando no sea posible controlar las elevaciones postprandiales de la glucemia o prevenir hipoglucemias nocturnas y severas con insulina humana. El análogo de acción larga Detemir podrá ser usado durante el embarazo, una vez aprobado por los organismos nacionales correspondientes. Se requieren estudios aleatorios controlados en embarazadas para Glargina y de costo-efectividad para todos los análogos de la insulina.

Insulin analogues have been used in the treatment of diabetes in pregnancy and some of them off-label. To know the efficacy and safety of insulin analogues concerning mother and fetus, a literature review on the subject was carried out. Regarding Glulisine, there are no reports on its use on gestation. On Lispro, there are few randomized studies comparing its use to regular human insulin, however, there are several observational studies, mostly retrospective, that do not reveal an increased risk. On Aspart, research has been done on women with type 1 diabetes during pregnancy with a randomized controlled clinical trial comparing it to regular human insulin; its results were used as a basis for its approval in pregnant women. On Glargine, observational studies have been carried out, but none were randomized controlled. On Detemir, a randomized controlled trial that ended in 2011 was carried out, comparing it to NPH human insulin; its results supported the recent approval by the Federal Drug Administration (FDA) to be used in pregnant women. In conclusion, Lispro and Aspart are the options of fast-action analogues for use during pregnancy when the control of glucose postprandial elevations or the prevention of nocturnal and severe hypoglycemia with human insulin is not possible. The long-lasting analogue Detemir may be used during pregnancy, once it has been approved by national drug regulations. Randomized controlled studies during pregnancy are required for Glargine and cost-efficacy studies for all insulin analogues.

Insulin analogues in the treatment of diabetes in pregnancy / Análogos de insulina no tratamento do diabetes gestacional

Pregnancy affects both maternal and fetal metabolism, and even in non-diabetic women, it exerts a diabetogenic effect. Among pregnant women, 2% to 14% develop gestational diabetes. Pregnancy can also occur in women with preexisting diabetes, which may predispose the fetus to many alterations in organogenesis, restrict growth, and the mother, to some diabetes-related complications, such as retinopathy and nephropathy, or to acceleration of the course of these complications, if they are already present. Women with gestational diabetes generally start their treatment with diet and lifestyle changes; when these changes are not enough for optimal glycemic control, insulin therapy must then be considered. Women with type 2 diabetes using oral hypoglycemic agents are advised to change to insulin therapy. Those with preexisting type 1 diabetes should start intensive glycemic control. As basal insulin analogues have frequently been used off-label in pregnant women, there is a need to evaluate their safety and efficacy. The aim of this review is to report the use of both short- and long-acting insulin analogues during pregnancy and to enable clinicians, obstetricians, and endocrinologists to choose the best insulin treatment for their patients.

A gravidez afeta tanto o metabolismo materno quanto o fetal e, mesmo em mulheres não diabéticas, apresenta um efeito diabetogênico. Entre as mulheres grávidas, 2% a 14% desenvolvem o diabetes gestacional. A gravidez pode ocorrer também em mulheres já diabéticas, o que pode predispor o feto a muitas alterações na organogênese, restrição de crescimento e a mãe a algumas complicações relacionadas ao diabetes, tais como retinopatia e nefropatia, ou acelerar o curso dessas complicações se já estiverem presentes. Pacientes com diabetes gestacional geralmente iniciam seu tratamento com dieta e mudanças no estilo de vida; porém, quando essas medidas falham em atingir um controle glicêmico adequado, a insulinoterapia deve ser considerada. Pacientes com diabetes tipo 2 em uso de hipoglicemiantes orais são aconselhadas a iniciar o uso de insulina. Pacientes com diabetes tipo 1 preexistente devem iniciar um controle glicêmico estrito. Em função do fato de os análogos basais de insulina estarem sendo utilizados muito frequentemente off-label em pacientes grávidas, faz-se necessário avaliar sua segurança e eficácia nessa condição. O objetivo desta revisão é avaliar o uso de tais análogos, tanto de ação curta como prolongada, durante a gravidez, para possibilitar médicos clínicos, obstetras e endocrinologistas escolher o melhor regime terapêutico para suas pacientes.

Comparison of thrice daily biphasic human insulin (30/70) versus basal detemir & bolus aspart in patients with poorly controlled type 2 diabetes mellitus – A pilot study.

Background & objectives: Conventionally, biphasic human insulin (30/70, BHI) is used twice daily for the management of patients with diabetes. However, this regimen is suboptimal to control post-lunch and/ or pre-dinner hyperglycaemia in some patients. This study was undertaken to compare the efficacy and safety of thrice-daily biphasic human insulin (30/70, BHI) versus basal detemir and bolus aspart (BB) in patients with poorly controlled type 2 diabetes mellitus (T2DM). Methods: In this open labelled randomized pilot study, 50 patients with uncontrolled T2DM on twicedaily BHI and insulin sensitizers were randomized either to BHI thrice-daily or BB regimen. HbA1c, six point plasma glucose profile, increment in insulin dose, weight gain, hypoglycaemic episodes and cost were compared between the two treatment groups at the end of 12 wk. Results: Mean HbAlc (±SD) decreased from 9.0±0.9 per cent at randomization to 7.9±0.8 per cent in BHI (P<0.001) and from 9.4±1.3 to 8.2±1.0 per cent in BB regimen (P<0.001) after 12 wk of treatment. The mean (±SEM) weight gain in patients in the BHI regimen was 1.5±0.33 kg compared to 1.4±0.34 kg in the BB regimen. Insulin dose increment at 12 wk was significantly more in the BB regimen 0.46±0.32 U/ kg/day compared to 0.15±0.21 U/kg/day in the BHI regimen (P<0.001). The incidence of major as well as minor hypoglycaemic episodes was not different in both the regimen. The BB regimen was more expensive than the BHI regimen (P<0.001). Interpretation & conclusions: The thrice daily biphasic human insulin regimen is non-inferior to the basal bolus insulin analogue regimen in terms efficacy and safety in patients with poorly controlled T2DM. However, these data require further substantiation in large long term prospective studies.

The Effects of Anti-insulin Antibodies and Cross-reactivity with Human Recombinant Insulin Analogues in the E170 Insulin Immunometric Assay / 대한진단검사의학회지

BACKGROUND: Insulin assays are affected by varying degrees of interference from anti-insulin antibodies (IAs) and by cross-reactivity with recombinant insulin analogues. We evaluated the usefulness of the E170 insulin assay by assessing IA effects and cross-reactivity with 2 analogues. METHODS: Sera were obtained from 59 type 2 diabetes patients receiving continuous subcutaneous insulin infusion and 18 healthy controls. Insulin levels were determined using an E170 analyzer. To investigate the effects of IAs, we performed IA radioimmunoassays, and analyzed the differences between directly measured insulin (direct insulin) and polyethylene glycol (PEG)-treated insulins (free, IA-unbound; total, IA-bound and unbound insulin). We performed in-vitro cross-reactivity tests with insulin aspart and insulin glulisine. RESULTS: In IA-positive patients, E170 free insulin levels measured using the E170 analyzer were significantly lower than the direct insulin levels. The mean value of the direct/free insulin ratio and IA-bound insulin, which were calculated as the difference between total and free insulin, increased significantly as endogenous IA levels increased. The E170 insulin assay showed low cross-reactivities with both analogues (< 0.7%). CONCLUSIONS: IAs interfered with E170 insulin assay, and the extent of interference correlated with the IA levels, which may be attributable to the increase in IA-bound insulin, and not to an error in the assay. The E170 insulin assay may measure only endogenous insulin since cross-reactivity is low. Our results suggest that the measurement of free insulin after PEG pre-treatment could be useful for beta cell function assessment in diabetic patients undergoing insulin therapy.

Pay more attention to the study of the relationship between diabetes mellitus and cancer / 中华内分泌代谢杂志

Diabetic patients are at increased risk of some cancers,mainly pancreatic cancer,liver cancer,colorectal cancer,breast cancer,endometrial cancer,etc.,and these cancers often result in higher mortalities than that in nondiabetics.The exact mechanism of this relationship is still unclear.The most suggested factor are hyperinsulinemia and insulin-like growth factors with their growth promoting and mitogenic effects.Recently,some insulin analogues are suspected to have these carcinogenic effects,but no firmly proven data are available yet.Metformin may have a protective effect in this regard.

Análogos en el Régimen Basal/Bolo: Insulinización oportuna en diabetes tipo 2

La diabetes es una patología difícil de tratar. Actualmente la insulina sigue siendo el pilar fundamental, y las estrategias de tratamiento de reemplazo tienen por finalidad reproducir el perfil de secreción normal de insulina, para lograr así el control efectivo en los niveles de glucemia basal y postprandial. Con una combinación adecuada de análogos de insulina, se puede lograr ése control óptimo de la glucemia, recomendado por las diferentes asociaciones y organizaciones mundiales, dedicadas al estudio y control de la diabetes. En este artículo se realiza una revisión sobre la fisiopatología de la diabetes mellitus Tipo 1 y Tipo 2, como base para dirigir el tratamiento usando las nuevas insulinas (análogos), en cada una de ellas. Pero necesitamos superar los mitos y las barreras, que tienen los médicos y sus pacientes, a los regímenes de tratamiento con insulina.

Diabetes is a difficult disease to treat. Currently, insulin is still the mainstay. Treatment strategies are aimed to reproduce the normal secretory profile of insulin to achieve the effective control in the fasting and postprandial plasma glucose levels. Mostly, with an appropriate combination of insulin analogues, an optimal control of blood sugar could be achieved, such as recommended by the different worldwide associations and organizations, dedicated to the study and control care of diabetes. This article is a review of the pathophysiology of Type 1 and Type 2 diabetes mellitus as the support for treatment in each one of its, but we still need to dispel myth and removing barriers of acceptance about these insulin regimens treatments in physicians and patients.

Comparison of various insulin analogues in the treatment of diabetes by two different injection methods / 中华内分泌代谢杂志

The efficacy of different kinds of insulin analogue administered by multiple subcutaneous injection or continuous insulin infusion was compared. The two forms of administration all can well control blood glucose. Continuous subcutaneous injection has better compliance.

Comparison of efficacy and safety of three regiments of transient intensive insulin therapy / 中华内分泌代谢杂志

Objective To compare the efficacy and safety of three regiments of transient intensive insulin therapy for type 2 diabetes mellitns: thrice preprandial injection of premixed insulin aspart 30, thrice preprandial injection of insulin aspart and injection of glargine at bedtime, thrice preprandial injection of regular insulin and injection of NPH at bedtime. Methods Patients were randomly divided into 3 groups, treated with 3 kinds of intensive insulin therapy. After achieving the target goal, continuous glucose monitoring system was used to compare the blood glucose level, therapeutic time, dosage of insulin, occurrence of hypoglycemia. Results Detected by continuous glucose monitoring system, there was no statistical difference in average blood glucose [(8.3±2.1,7.5±1.9, 6.8±0.8) mmol/L, P > 0.05], blood glucose area under curve 3 hours (AUC1-3) after breakfast, therapeutic time [ (8.3±2.5, 9.1±3.8, 8.4±1.7)d, P > 0.05], dosage of insulin [(0.63± 80%, P > 0.05) among three kinds of transient intensive insulin therapy. There were no patients complaining of hypoglycemic symptom. Conclusion The short-term efficacy and safety among three intensive insulin therapeutic methods are similar. More attention should be paid to monitor the blood glucose during sleep.
