[Non-Insulin Antidiabetic Agents in the Management of Hyperglycaemia of Non-Critical Hospitalized Patients]. / Antidiabéticos Não Insulínicos na Abordagem da Hiperglicemia nos Doentes Hospitalizados por Doença Aguda Não Crítica.

Hyperglycaemia affects more than 30% of adults hospitalized for non-critical illness and is associated with an increased risk of adverse clinical outcomes. Insulin therapy is widely used for its safety and efficacy. However, given the growing availability of new drugs and new classes of antidiabetic agents with benefits beyond glycaemic control, challenges arise regarding their use in the hospital setting. This article aims to review and summarize the most recently available evidence and recommendations on the role of non-insulin antidiabetic agents in the management of hyperglycaemia in hospitalized patients. Insulin therapy remains the method of choice. Dipeptidyl peptidase 4 inhibitors can be considered in mild to moderate hyperglycaemia. Glucagon-like peptide 1 receptor agonists have recently shown promising results, with high efficacy in glycaemic control and low risk of hypoglycaemia. There are concerns regarding the increased risk of acidosis with metformin use, especially in cases of acute illness, although there is no evidence to support its suspension in selected patients with relative clinical stability. Sodium-glucose cotransporter-2 inhibitors should be discontinued in clinical situations that may predispose to ketoacidosis, including episodes of acute illness. The hospital use of sulfonylureas and thiazolidinediones is not advised.

A hiperglicemia afeta mais de 30% dos adultos hospitalizados por doença não crítica e está associada a um risco aumentado de desfechos clínicos adversos. A insulinoterapia é amplamente utilizada pela sua segurança e eficácia. Contudo, face à disponibilidade crescente de novos fármacos antidiabéticos com benefícios além do controlo glicémico, surgem desafios quanto à sua utilização em contexto hospitalar. Este artigo tem como objetivo rever e sumariar a evidência e as recomendações mais recentemente disponibilizadas sobre o papel dos antidiabéticos não insulínicos na gestão da hiperglicemia a nível hospitalar. A insulinoterapia mantém-se como o método de eleição. Os inibidores da dipeptidil peptidase 4 podem ser considerados em casos de hiperglicemia ligeira a moderada, como alternativa ou de forma complementar à insulinoterapia. Os agonistas dos recetores do glucagon-like peptide 1 têm recentemente revelado resultados promissores, com elevada eficácia no controlo glicémico e risco baixo de hipoglicemia. Existem preocupações relativas ao risco acrescido de acidose com a metformina, sobretudo em casos de doença aguda, apesar de não existir evidência que suporte a sua suspensão em doentes selecionados e com relativa estabilidade clínica. Os inibidores do cotransportador de sódio-glicose-2 devem ser descontinuados em situações clínicas que possam predispor a cetoacidose, incluindo episódios de doença aguda. A utilização hospitalar das sulfonilureias e das tiazolidinedionas é desaconselhada.

Factores de riesgo que influyen en el desarrollo de la retinopatía diabética / Factors of risk that bear upon the development of diabetic retinopathy

RESUMEN Introducción: La retinopatía diabética es una microangiopatía retiniana. Provoca cambios anatómicos progresivos en la retina de pacientes diabéticos de larga evolución, es la tercera causa de ceguera a nivel mundial y primera en personas de edad productiva en países en vías de desarrollo, que conlleva a pérdida irreversible de la visión si no se diagnostica y se trata a tiempo. Objetivo: Describir el comportamiento de los factores de riesgo en los pacientes con retinopatía diabética que asistieron a la consulta de retina. Métodos: Se realizó un estudio observacional, descriptivo, transversal en 115 pacientes que acudieron a la consulta de retina con diagnóstico de retinopatía diabética en el periodo de octubre 2020 a febrero 2021 y cumplieron con los criterios de inclusión, se aplicó un formulario para recoger los datos. Los resultados se relacionaron con las variables: tipo de diabetes (tipo I, tipo II), tratamiento actual, control glucémico, factores de riesgo de retinopatía diabética y severidad de esta. Resultados: Fueron más frecuente los pacientes con diabetes tipo II y la retinopatía diabética proliferativa, en pacientes con diabetes tipo I. El tratamiento con hipoglucemiantes orales fue más frecuente seguido de la insulina, la mayor cantidad de pacientes presentaron control glucémico deficiente, el mayor número de pacientes tenían más de 15 años de enfermedad como factor de riesgo, seguida de la hipertensión arterial. Solo la nefropatía no se comportó como factor de riesgo. Conclusiones: La diabetes tipo II fue más prevalente. La retinopatía diabética proliferativa fue más frecuente en pacientes con diabetes tipo I. Los hipoglucemiantes orales constituyen el tratamiento más utilizado. La insulina se utilizó en pacientes con retinopatía diabética no proliferativa severa y retinopatía diabética proliferativa. Predominó el deficiente control glucémico. A mejor control glucémico menos severidad de la retinopatía diabética. Existió asociación estadística entre retinopatía diabética y la mayoría de los factores de riesgo.

ABSTRACT Introduction: Diabetic retinopathy is a retinal microangiopathy that provokes anatomical progressive changes in the retina of the patients with diabetes mellitus of long evolution, it is the third worldwide cause of blindness but the first in old fellows productive in developing countries, that it entails an irreversible loss of vision if one does not diagnose and he talks to each other in good timing. Objective: To describe the behavior of the risk factors in the patients with diabetic retinopathy that attended the retinal consultation of the Hospital Universitario Manuel Ascunce Domenech. Methods: A descriptive transverse study, in diabetic patients that attended the retinal consultation with the diagnosis of diabetic retinopathy was carried out in the period understood of October from 2020 to February 2021. The population was composed of 115 diabetic patients that attended the consultation, and they fulfilled the criteria of inclusion, they were applied a fill-out form to pick up data. The results related with the following variables: Type of diabetes (type 1, type 2), present-day treatment, glycemic control and risk factors of diabetic retinopathy and severity of the same. Results: It was more frequent the patients with diabetes type 2, and the proliferative diabetic retinopathy in patients with diabetes type 1. The treatment with hypoglycemic pray to them it was more frequent in frequent users of insulin, the most patients presented glycemic deficient control, the bigger number of patients they had more of 15 years of disease as risk factor, followed of high blood pressure. Only nephropathy did not entail itself as risk factor. Conclusions: Diabetes type 2 was more frequent than diabetes type 1. The proliferative diabetic retinopathy was frequent in the patients with diabetes type 1. The treatment more used was the oral hypoglycemic ones. Insulin was the treatment used in patients with diabetic retinopathy not proliferative severe and proliferative diabetic retinopathy. The bigger group presented deficient glycemic control. To better glycemic control less severity of her diabetic retinopathies. There was statistical association between diabetic retinopathy and most of the risk factors.

ABSTRACT Introduction Type 2 diabetes mellitus is one of the non transmissible chronic illnesses which have increased in prevalence during the last decades worldwide. Among the related treatments is the insulin based therapy. Nevertheless, the multiple and diverse controlled and commercial options of this therapy have generated confusion among both the users and health staff. Objective To describe some insulin-based therapy approaches to type 2 diabetes mellitus. Development The related technological advances have produced new diverse analog forms of insulin-based therapies. Among these, inhaling and blended forms can be highlig- hteddue to their efficacy in glucose control. Among the blended mixture, administration forms are the intensive action and the mobile action ones, which can use a human insulin analog as the key therapy element. The public systems, including the Chilean, have an important security role in the supervision and monitoring of the proper and correct dose administrations. Conclusion The diverse forms of insulin-based therapies for patients with type 2 diabetes mellitus include those with prolonged action insulin analogs but their use should be based on integral knowledge in order to avoid adverse effects. The findings of this review should be considered with caution due to the methodological limitations derived from the study design.

Glycemic Monitoring and Management in Advanced Chronic Kidney Disease.

Glucose and insulin metabolism in patients with diabetes are profoundly altered by advanced chronic kidney disease (CKD). Risk of hypoglycemia is increased by failure of kidney gluconeogenesis, impaired insulin clearance by the kidney, defective insulin degradation due to uremia, increased erythrocyte glucose uptake during hemodialysis, impaired counterregulatory hormone responses (cortisol, growth hormone), nutritional deprivation, and variability of exposure to oral antihyperglycemic agents and exogenous insulin. Patients with end-stage kidney disease frequently experience wide glycemic excursions, with common occurrences of both hypoglycemia and hyperglycemia. Assessment of glycemia by glycated hemoglobin (HbA1c) is hampered by a variety of CKD-associated conditions that can bias the measure either to the low or high range. Alternative glycemic biomarkers, such as glycated albumin or fructosamine, are not fully validated. Therefore, HbA1c remains the preferred glycemic biomarker despite its limitations. Based on observational data for associations with mortality and risks of hypoglycemia with intensive glycemic control regimens in advanced CKD, an HbA1c range of 7% to 8% appears to be the most favorable. Emerging data on the use of continuous glucose monitoring in this population suggest promise for more precise monitoring and treatment adjustments to permit fine-tuning of glycemic management in patients with diabetes and advanced CKD.

Recommendations for improving clinical trial design to facilitate the study of youth-onset type 2 diabetes.

BACKGROUND: The prevalence of type 2 diabetes is increasing in youths and differs from adult-onset type 2 diabetes in its characteristics and progression. Currently, only two drugs are approved for youth-onset type 2 diabetes and many patients are not meeting glycemic targets. Clearly, there is an urgent need to complete clinical trials in youths with type 2 diabetes to increase the therapeutic choice for these patients. However, factors such as limited patient numbers, unwillingness of patients to participate in trials, failure to meet strict inclusion and exclusion criteria, and poor clinic attendance have limited the size and number of trials in this complicated patient demographic. RECOMMENDATIONS: This is a narrative opinion piece on the design of clinical trials in youth-onset type 2 diabetes prepared by researchers who undertake this type of study in different countries. The review addresses possible ways to enhance trial designs in youth-onset type 2 diabetes to meet regulatory requirements, while minimizing the barriers to patients' participation. The definition of adolescence, recruitment of sufficient patient numbers, increasing flexibility in selection criteria, improving convenience of trial visits, requirements of a control group, possible endpoints, and trial compliance are all considered. The authors recommend allowing extrapolation from adult data, using multiple interventional arms within future trials, broadening inclusion criteria, and focusing on endpoints beyond glucose control, among others, in order to improve the successful completion of more trials in this population. CONCLUSIONS: Improvements in trial design will enable better recruitment and retention and thereby more evidence for treatment outcomes for youth-onset type 2 diabetes.

The inspection of sitagliptin to metabolic index and carotid artery IMT in metabolic syndrome patients with type 2 diabetes / 中国医师杂志

Objective To evaluate the effects of sitagliptin on blood glucose,blood pressure,blood lip and carotid artery intima media thickness (IMT) in metabolic syndrome patients with type 2 diabetes.Methods The clinical data were collected for 64 cases of inpatient and outpatient patients with metabolic syndrome with type 2 diabetes.Those patients included anti-diabetes native patients and patients only used the stable metformin dose.After signed off the informed consent form,those patients were randomized to the sitagliptin treatment group or original treatment group,and the metabolic index and carotid artery intima-media thickness were evaluated after 24 weeks treatment.Results The body mass index (BMI),waist circumference (WC),fasting plasma glucose (FPG),triglycerides (TG),high density lipoprotein cholesterol (HDL-C),systolic blood pressure (SBP),diastolic blood pressure (DBP),glycated hemoglobin a1c (HbA1c),and carotid artery IMT in two groups were comparable at baseline.After 12 weeks treatment,the FPG,TG,DBP,and HbA1c in the sitagliptin group were significantly better than original treatment group and the baseline,while there was no different between two groups in other index.After 24 weeks treatment,the FPG,TG,HDL-C,DBP,HbA1c,and carotid artery IMT in the sitagliptin group were significantly better than original treatment group and the baseline.Conclusions Sitagliptin presents the functions of lowering blood pressure,adjusting blood lipid,and protecting vascular endothelial in addition to lowering blood glucose.

Therapeutic effect of sitagliptin combined insulin in treatment of type 2 Diabetes / 中国医师杂志

Objective To explore the clinical effect of sitagliptin combined insulin compared to those patients whose sugars were not well controlled by insulin alone.Methods The eighty type 2 Diabetes patients whose BMI≥24 kg/m2 and used insulin alone were randomly divided into sitagliptin combined insulin group (40 cases) who were given sitagliptin 100mg/d allied with insulin,an insulin group (40 cases) who were given insulin alone.After 12 weeks,the change of body mass index (BMI),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1 c),β-cell function index(HOMA-β),insulin resistance index (HOMA-IR),insulin quantities,and hypoglycemia rates were observed in two groups.Results Compared with pretherapy,the levels of FPG,2 h BG,HbAlc,HOMA-IR,and hypoglycemia rates were significantly decreased (P ＜0.05) ; BMI was increased in insulin group,while was not increased in sitagliptin combined insulin group.After the treatment,the insulin quantities were decreased in the combined group while increased in the control group (P ＜ 0.05).Conclusions Sitagliptin combined insulin can effectively control glucose levels of type 2 diabetes patients,decrease the insulin quantities and the risk of hypoglycemia,and does not increase the weight.
