Introducción: El 50% de la población mundial usa tratamientos alternativos como productos herbarios. El 20% los consume de manera simultánea con algún tratamiento farmacológico para el control la Diabetes Mellitus tipo 2; enfermedad prevalente en adultos mayores. Es escasa la información acerca de las interacciones medicamentosas que pudieran producirse, siendo responsables de más de 7,000 muertes al año. Objetivo: Identificar los productos herbarios de mayor consumo del Adulto Mayor con Diabetes Mellitus Tipo 2, en Chapulco, Puebla, México y describir las posibles interacciones medicamentosas entre fármaco hipoglucemiante ­ producto herbario reportados en la literatura científica. Metodología: Estudio observacional, prolectivo, transversal, descriptivo, en una población de 35 adultos mayores diabéticos, con edad promedio de 70±7 años. Para la identificación de los productos herbarios de uso común y sus aplicaciones terapéuticas se aplicó el cuestionario U-PLANMED. Resultados: Se identificaron 50 productos herbarios y 18 combinaciones entre estos a la vez. El 40% de los participantes consumen simultáneamente más de dos productos herbarios con uno o dos fármacos hipoglucemiantes. Entre los productos de mayor consumo se encuentran el nopal (Opuntia ficus-indica L.), la manzanilla (Matricaria chamomilla L.) y el zacate de limón (Cymbopogon citratus DC. Stapf.). Las interacciones medicamentosas potenciales identificadas, principalmente en estudios experimentales en animales, sugieren que, existe una acción hipoglucemiante del producto herbario al aumentar la capacidad orgánica sobre la secreción/liberación de insulina endógena. Conclusiones: Se ha evidenciado la presencia de interacciones medicamentosas ante el consumo simultaneo de fármacos prescritos para el control de la diabetes mellitus tipo 2 con productos herbarios. Es necesario que, los profesionales en atención a la salud identifiquen el uso de dichos productos y orienten a los adultos mayores sobre las posibles repercusiones en los niveles de glucosa ante el consumo.

Introduction: 50% of the world's population uses alternative treatments such as herbal products. Twenty percent use them in conjunction with some form of pharmacological treatment to control type 2 diabetes mellitus, a disease prevalent in older adults. There is little information on the drug interactions that may occur, which are responsible for more than 7,000 deaths per year. Objective: To identify the most consumed herbal products among older adults with type 2 diabetes mellitus in Chapulco, Puebla, Mexico, and to describe the possible drug-drug interactions between hypoglycemic drugs and herbal products reported in the scientific literature. Methodology: Observational, prospective, cross-sectional, descriptive study in a population of 35 diabetic older adults with a mean age of 70±7 years. The U-PLANMED questionnaire was used to identify commonly used herbal products and their therapeutic applications. Results: Fifty herbal products and 18 combinations of them were identified. Forty percent of the participants used more than two herbal products simultaneously with one or two hypoglycemic drugs. The most used products included prickly pear cactus (Opuntia ficus-indica L.), chamomile (Matricaria chamomilla L.), and lemon grass (Cymbopogon citratus DC. Stapf.). Potential drug-drug interactions identified mainly in experimental animal studies suggest that there is a hypoglycemic effect of the herbal product by increasing the organic capacity on endogenous insulin secretion/release. Conclusions: The presence of drug-drug interactions has been demonstrated with the simultaneous consumption of drugs prescribed for the control of type 2 diabetes mellitus with herbal products. It is necessary for health care professionals to recognize the use of such products and to inform older adults about the possible repercussions on glucose levels when consuming them.

Introdução: 50% da população mundial utiliza tratamentos alternativos como os produtos à base de plantas. Vinte por cento utilizam-nos em conjunto com algum tipo de tratamento farmacológico para controlar a diabetes mellitus tipo 2, uma doença prevalente em adultos mais velhos. Há pouca informação sobre as interacções medicamentosas que podem ocorrer e que são responsáveis por mais de 7.000 mortes por ano. Objetivos: Identificar os produtos fitoterápicos mais consumidos entre os idosos com diabetes mellitus tipo 2 em Chapulco, Puebla, México, e descrever as possíveis interações medicamentosas entre medicamentos hipoglicemiantes e produtos fitoterápicos relatados na literatura científica. Metodologia: Estudo observacional, prospetivo, transversal e descritivo numa população de 35 idosos diabéticos com uma idade média de 70±7 anos. O questionário U-PLANMED foi utilizado para identificar os produtos fitoterápicos mais utilizados e suas aplicações terapêuticas. Resultados: Foram identificados 50 produtos à base de plantas e 18 combinações dos mesmos. Quarenta por cento dos participantes utilizaram mais de dois produtos à base de plantas em simultâneo com um ou dois medicamentos hipoglicemiantes. Os produtos mais utilizados foram o cato de figo da Índia (Opuntia ficus-indica L.), a camomila (Matricaria chamomilla L.) e o capim-limão (Cymbopogon citratus DC. Stapf.). As potenciais interacções medicamentosas identificadas principalmente em estudos experimentais em animais sugerem que existe um efeito hipoglicémico do produto à base de plantas através do aumento da capacidade orgânica na secreção/libertação de insulina endógena. Conclusões: A presença de interacções medicamentosas foi demonstrada com o consumo simultâneo de medicamentos prescritos para o controlo da diabetes mellitus tipo 2 com produtos à base de plantas. É necessário que os profissionais de saúde reconheçam o uso de tais produtos e informem os idosos sobre as possíveis repercussões nos níveis de glicose ao consumi-los.

Evaluation of blood glucose controlling efficacy of various oral hypoglycemic drugs in Type 2 diabetes mellitus patients: A prospective, randomized, and control study

Background: This study was conducted to evaluate the effect of various oral hypoglycemic agents in the control of plasma blood glucose levels among Type 2 diabetes mellitus (T2DM) patients. Aims and Objectives: This study is aimed to evaluate the blood glucose controlling efficacy of various oral hypoglycemic drugs in T2DM patients. Materials and Methods: This randomized and control study was conducted among the cases attending Department of General Medicine at Research cell of Chennai Medical College Hospital and Research Centre, during the period of June 2014 to July 2015. A total of 180 cases were randomly allotted to six groups. Group I was treated with Glibenclamide, Group-II was treated with Glibenclamide + Sitagliptin, Group-III was treated with Glibenclamide + Vildagliptin, Group-IV was treated with Metformin, Group-V was treated with Metformin + Sitagliptin, and Group-VI was treated with Metformin + Vildagliptin. Fasting, postprandial, and glycated hemoglobin (HbA1c) levels were assessed before and at 4, 8, and 12th weeks and the data were analyzed using Statistical Package for the Social Sciences. Results: Fasting and postprandial sugars were significantly reduced in Group V and Group VI during 4th, 8th, and 12th weeks. However, HbA1c levels were significantly reduced after 12 weeks of treatment in Group III, Group V, and Group VI. Conclusion: We conclude that metformin in combination with either Vildagliptin or Sitagliptin can help to reduce fasting, postprandial, and HbA1c levels (both in short-term and in long-term); however, Glibenclamide along with Vildagliptin could reduce only HbA1c levels (long-term alone).

Therapeutic effects of insulin degludec/insulin aspart on type 2 diabetes mellitus in patients with poor efficacy of oral hypoglycemic drugs / 中国基层医药

Objective:To investigate the clinical efficacy of insulin degludec/insulin aspart on type 2 diabetes mellitus in patients with poor efficacy of oral hypoglycemic drugs.Methods:A total of 100 patients with type 2 diabetes mellitus in Tianfu Hospital of Chongqing Energy Investment Health Industry Company Limited from August 2020 to August 2021 were included in this study. They were randomly assigned to receive either insulin degludec/insulin aspart combined with Metformin (observation group, n = 50) or nsulin aspart 30 injection and Metformin (control group, n = 50). All patients were treated for 3 months. Changes in fasting plasma glucose level, 2-hour postprandial glucose level , and HbAlc after treatment relative to those before treatment as well as clinical efficacy were determined in each group. Results:Forty-eight patients in the observation group and forty-six patients in the control group completed the course of treatment. Fasting blood glucose level and 2-hour postprandial glucose level in the observation group were (6.24 ± 1.12) mmol/L and (8.34 ± 2.34) mmol/L, respectively and they were significantly lower than (6.91 ± 1.86) mmol/L and (10.72 ± 2.48) mmol/L, respectively in the control group ( t = 3.28, 4.76, both P < 0.05). The level of HbAlc was not significant between the two groups ( P > 0.05). The hypoglycemia rate in the observation group was significantly lower than that in the control group [2% (1/48) vs. 13% (6/46), χ2 = 4.09, P < 0.05]. The daily dose of insulin in the observation group was less than that in the control group [(13.5 ± 2.8) IU vs. (15.6 ± 3.1) IU, t = 3.28, P < 0.05)]. Conclusion:Compared with insulin insulin aspart 30, the insulin degludec/insulin aspart has a stronger hypoglycemic effect on fasting plasma glucose level and 2-hour postprandial glucose level in the treatment of type 2 diabetes mellitus in patients with poor efficacy of oral hypoglycemic drugs, leading to a less daily dose of insulin.

Clinical study on dapagliflozin combined with metformin for the treatment of type 2 diabetes mellitus / 中国基层医药

Objective:To investigate the clinical effect of dapagliflozin combined with metformin on type 2 diabetes mellitus (T2DM).Methods:A total of 100 patients with T2DM who received treatment in The Second People's Hospital of Hefei from June 2019 to May 2021 were included in this study. They were randomly divided into a control group ( n = 50) and an experimental group ( n = 50). The control group was treated with metformin, and the experimental group was treated with dagglitazin combined with metformin. All patients were treated for 3 months. Blood glucose index, blood lipid level, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, fasting blood glucose, 2-hour post-prandial blood glucose, and glycosylated hemoglobin in the experimental group were (5.56 ± 0.37) mmol/L, (8.32 ± 0.23) mmol/L, and (6.17 ± 0.26)% respectively, which were significantly lower than (6.96 ± 0.48) mmol/L, (9.58 ± 0.39) mmol/L, and (7.27 ± 0.26)% respectively in the control group ( t = 3.59, 6.92, 5.03, all P < 0.05). The total cholesterol and triglyceride in the experimental group were (3.58 ± 0.53) mmol/L and (1.25±0.26) mmol/L, respectively, which were significantly lower than (4.94 ± 0.58) mmol/L and (1.93 ± 0.18) mmol/L in the control group ( t = 3.16, 4.25, both P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Dapagliflozin combined with metformin can effectively control blood glucose and blood lipid in T2DM patients without increasing adverse reactions.

Opportunities and challenges of incretin-based hypoglycemic agents treating type 2 diabetes mellitus from the perspective of physiological disposition

The treatment of patients with diabetes mellitus, which is characterized by defective insulin secretion and/or the inability of tissues to respond to insulin, has been studied for decades. Many studies have focused on the use of incretin-based hypoglycemic agents in treating type 2 diabetes mellitus (T2DM). These drugs are classified as GLP-1 receptor agonists, which mimic the function of GLP-1, and DPP-4 inhibitors, which avoid GLP-1 degradation. Many incretin-based hypoglycemic agents have been approved and are widely used, and their physiological disposition and structural characteristics are crucial in the discovery of more effective drugs and provide guidance for clinical treatment of T2DM. Here, we summarize the functional mechanisms and other information of the drugs that are currently approved or under research for T2DM treatment. In addition, their physiological disposition, including metabolism, excretion, and potential drug-drug interactions, is thoroughly reviewed. We also discuss similarities and differences in metabolism and excretion between GLP-1 receptor agonists and DPP-4 inhibitors. This review may facilitate clinical decision making based on patients' physical conditions and the avoidance of drug-drug interactions. Moreover, the identification and development of novel drugs with appropriate physiological dispositions might be inspired.

Biochemical evaluation of DPP4 inhibitors on lipid profile in type 2 diabetes mellitus patients: A hospital-based prospective study

Background: Lipid lowering action of oral hypoglycemic drugs is still unclear. Hence, this study was conducted to address the same using monotherapy and with combination of oral hypoglycemic in patients suffering with type 2 diabetes. Aims and Objectives: The main aim and objective of the study was to evaluate the DPP4 inhibitors inducted changes in low-density lipoprotein (LDL), VLSL, high-density lipoprotein (HDL), and total cholesterol (TC) in patients suffering with type 2 diabetes. Materials and Methods: This randomized control study was done in the Department of General Medicine, Chennai Medical College Hospital and Research Center, Irungalur, Tiruchirappalli, between June 2014 and July 2015. Cases with type 2 diabetes mellitus (T2DM) aged 30–70 years who had been on glibenclamide or metformin for the past 3 months and had uncontrolled blood glucose levels were selected for the study. Total 180 patients are fulfilling the inclusion and exclusion criteria were divided into six groups (Each with 30 patients.) At the 0th and 12th weeks, fasting lipid profile was assessed. The data were expressed in number, percentage, mean, and standard deviation. Results: Oral hypoglycemic drug either as monotherapy or in combination has significant effect on lipid profile among the cases with T2DM. Furthermore, the significant decrease in TC and maximum improvement in HDL was noted with the use of glibenclamide in combination with Sitagliptin and maximum reduction in triglycerides and LDL was noted with the use of Metformin in combination with Sitagliptin. Conclusion: Oral hypoglycemic agents have an additional favorable effect on lipid profile among the cases with T2DM.

Perfiles de hipoglicemiantes e insulinas en pacientes con diabetes mellitus tipo 2 y su efecto en control metabólico, hipoglicemia y otros efectos adversos / Profile of glucose lowering drug use in outpatients with type 2 diabetes mellitus

BACKGROUND: The use of glucose lowering agents with favorable weight profile is a growing practice in Diabetology. AIM: To characterize medication combinations in patients with type 2 Diabetes (T2D) and their effect on metabolic control. MATERIAL AND METHODS: Review of medical records of 249 outpatients with T2D with a median age of 66 years, cared for at a medical network. Clinical characteristics, glycated hemoglobin (HbA1c), details of Diabetes treatment (types of drugs or insulin), renal function, lipids and B12 vitamin levels were registered. RESULTS: The median disease duration was 16 years. The most recent HbA1c was 7.4%. No patient was using sulfonylureas, 45 were using Dipeptidyl peptidase 4 inhibitors, 113 were using Sodium-glucose Cotransporter-2 (SGLT2i) Inhibitors, 21 used Glucagon-like Peptide-1 Receptor Agonists (GLP1ra), 158 used basal insulin and 61 on basal plus bolus insulin. The use of SGLT2i or GLP1ra was associated with a metabolic control similar to those patients not using them, while patients on rapid insulin had a significantly worse metabolic control and a tendency to greater body mass index. The use of basal insulin and rapid insulin was significantly associated with more hypoglycemia events. CONCLUSIONS: The use of SGLT2i and GLP1ra in patients with T2D is associated with better metabolic control than rapid insulin with less risk of hypoglycemia. The use of these therapies should be prioritized in the future.

Prescription of DPP4 inhibitors: Indication and effect on glycosylated hemoglobin in a primary care institution of Colombia / Prescripción de inhibidores de la DPP-4: indicación y efecto sobre la hemoglobina glicosilada en un primer nivel de Colombia

Abstract Introduction and objective: In Colombia, Dipeptidyl-Peptidase IV (DPP4) inhibitors are recommended as second-best choice for type 2 diabetes mellitus treatment. However, no evaluation of the accomplishment or impact of this recommendation was performed. The objective was to determine the prescription of the DPP4 inhibitor according to the Colombian Clinicial Practice Guide regarding type 2 diabetes mellitus treatment, and its effects on glycosylated hemoglobin (HbAlc). Materials and methods: A descriptive study that included patients with type 2 diabetes mellitus who attended a first level between 2016 and 2018, had a prescription for DPP4 inhibitor and at least two control appointments. Variables included were sociodemographic, clinics, treatment and comorbidities. The unadjusted prescription was defined as the lack of accomplishment of Colombian guidelines. Descriptive statistics and X2 test were used for the comparison of categorical variables. A binary logistic regression model was applied. Results: 112 out of 207 patients accomplished inclusion criteria, of which 77 were women (68.8%). Also, 68.8% of the patients had an unadjusted prescription of the iDPP4. There was a 0.21% total reduction in HbA1c levels, with a mean of 198.2 ± 124 days between the first and second control measurement (reduction of 0.55% when the prescription was adjusted to the guidelines and 0.05% if it was unadjusted). Conclusion: There is a limited impact of DPP4 inhibitors regarding the reduction of HbA1c and metabolic control, and there is a slight follow-up to the Colombian guidelines in patients who attend a first level.

Resumen Introducción y Objetivo: En Colombia se recomiendan los inhibidores de la Dipeptidil Peptidasa-IV (iDPP4) como segunda opción para el manejo de la diabetes mellitus tipo 2. No se ha evaluado el cumplimiento e impacto de esta recomendación. Como objetivo se buscó determinar la prescripción de los iDPP4 según las recomendaciones de la Guía de Práctica Clínica colombiana, y su efecto sobre la hemoglobina glicosilada (HbA1c). Materiales y métodos: Estudio descriptivo que incluyó pacientes con diabetes mellitus tipo 2 que consultaron a un primer nivel entre 2016 y 2018, y tenían formulado un iDPP4, con al menos dos consultas de seguimiento. Se incluyeron variables sociodemográficas, clínicas, tratamiento y comorbilidades. La prescripción no ajustada se definió como la falta de cumplimento de la recomendación de la guía colombiana. Se empleó estadística descriptiva y pruebas X2 para la comparación de variables categóricas. Se aplicó un modelo de regresión logística binaria. Resultados: Hubo 207 pacientes de los cuales 112 cumplieron criterios de inclusión, 77 eran mujeres (68,8%). El 68,8% de los pacientes presentaron una prescripción no ajustada del iDPP4. Hubo una reducción total de 0,21%, con una media de 198,2±124 días entre la primera y segunda medición de HbA1c de control (reducción de 0,55% cuando la prescripción se ajustaba a la guía colombiana y 0,05% cuando no). Conclusión: Hay un limitado impacto de los iDPP4 frente a la reducción de HbA1c y poco seguimiento de la guía colombiana en pacientes de primer nivel de atención.

Dentro de estos destacan los inhalatorios y premezclas por su eficacia en el control glucémico a través del tiempo, considerando las pautas de administración subcutánea en estas premezclas una serie de elementos como la zona de punción, seguridad y uso de pliegues. Dichas pautas han inducido la creación de diversos esquemas de insulinoterapia entre los que se destacan los métodos de acción intensiva y acción móvil, orientados a la simulación de la insulina fisiológica como mecanismo de acción para el control glucémico. La seguridad de estos mecanismos depende del sistema público de salud chileno para la dosificación, administración y control suministrado. Conclusión Las pautas y esquemas de insulinoterapia sugieren el uso de análogos de acción prolongada ante hiperglucemia; su uso requiere conocimiento integral de los pacientes y cuidadores con el fin de evitar efectos adversos. Los hallazgos de esta revisión deben ser considerados con cautela al momento de tomar decisiones clínicas producto de las limitaciones metodológicas propias del diseño utilizado.

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.

RESUMO Introdução O diabetes mellitus tipo 2 (DM2), é uma das doenças crônicas não transmissíveis que tem aumentado sua incidência nas últimas décadas no mundo todo, sendo suas diretrizes de tratamento e esquemas de insulinoterapia. No entanto, a grande disponibilidade comercial e o controle glicêmico atribuído à insulinoterapia têm gerado múltiplas confusões em usuários e profissionais de saúde. Objetivo Descrever as diretrizes e esquemas no tratamento do DM2. Desenvolvimento A evolução tecnológica da insulinoterapia envolve o uso de múltiplos análogos. Dentre estes, os inalantes e pré-misturas destacam-se por sua eficácia no controle glicêmico ao longo do tempo, considerando as orientações de administração subcutânea nessas pré-misturas uma série de elementos como área de punção, segurança e uso de dobras. Essas diretrizes levaram à criação de diversos esquemas de insulinoterapia, dentre os quais se destacam os métodos de ação intensiva e ação móvel, visando simular a insulina fisiológica como mecanismo de ação para o controle glicêmico.

Evaluación de la prescripción de hipoglucemiantes orales en población adulta con Diabetes Mellitus Tipo 2 / Evaluation of the prescription of oral hypoglycemic agents in the adult population with type 2 diabetes mellitus

En el nivel primario de atención se detectan errores en la prescripción del tratamiento farmacológico de la diabetes tipo 2. El objetivo de este estudio fue evaluar la calidad de la prescripción de hipoglucemiantes orales en pacientes atendidos en consultorios del médico de la familia del Policlínico Universitario Hermanos Cruz, municipio Pinar del Río, Cuba. Se realizó un estudio de utilización de medicamentos de tipo descriptivo y transversal clasificado dentro de estos como de indicación-prescripción con elementos de esquema terapéutico y de factores que condicionan los hábitos de prescripción. El universo estuvo conformado por 1575 pacientes con diagnóstico de diabetes mellitus tipo 2 tratados con hipoglucemiantes orales que pertenecían a los 20 consultorios médicos de la familia.La muestra de estudio se obtuvo por el método de muestreo no probabilístico (por conveniencia) (n=846). La información se obtuvo de la historia clínica y tarjeta control de los pacientes para adquirir estos medicamentos. Predominó la edad de 40-49 años, el sexo femenino y entre 5-10 años de evolución de la enfermedad. No se usó la primera línea de tratamiento en el 43,6 % de los casos, ningún caso tenía estudios de laboratorio para el uso de la Metformina. La prescripción y dosis fue adecuada no así su uso racional. Las interacciones más frecuentes fueron las farmacocinéticas.El uso racional de hipoglucemiantes orales fue deficiente lo que hace necesario ampliar la divulgación de un protocolo de tratamiento para mejorar el uso de estos fármacos en el nivel primario de atención.

Errors in the prescription of drug treatment for type 2 diabetes are detected at the primary level of care. the purpose of this study was to evaluate the quality of the prescription of oral hypoglycemic agents in patients attended in the family doctor's offices of the Hermanos Cruz University Polyclinic, Pinar del Río distrit, Cuba. A descriptive and cross-sectional study of the use of medications was carried out, classified within these as indication-prescription with elements of the therapeutic scheme and factors that condition prescription habits. The universe was made up of 1575 patients diagnosed with type 2 diabetes mellitus treated with oral hypoglycemic agents who belonged to the 20 family medical offices. The study sample was carried out by the non-probabilistic sampling method (for convenience) (n = 846). The information was obtained from the clinical history and control card of the patients to acquire these medications. The age of 40-49 years, the female sex and between 5-10 years of evolution of the disease predominated. The first line of treatment was not used in 43.6% of the cases; no case had laboratory studies for the use of Metformin. The prescription and dose was adequate, but not its rational use. The most frequent interactions were pharmacokinetic ones.The rational use of oral hypoglycemic agents was deficient, which makes it necessary to expand the dissemination of a treatment protocol to improve the use of these drugs at the primary level of care.

Fármacos para o tratamento do diabetes mellitus tipo 2: interferência no peso corporal e mecanismos envolvidos / Drugs of the treatment of type 2 diabetes mellitus: interference with body weight and mechanisms involved

A quantidade de pessoas obesas vem crescendo significativamente em todo o mundo.Esse fato representa um risco para o aumento do número de portadores de diabetes mellitus tipo 2. A farmacoterapia do diabetes pode alterar o peso corporal, auxiliando tanto na perda como no ganho ponderal. Diante disso, o objetivo do presente trabalho foi revisar os fármacos utilizados no tratamento da diabetes tipo 2 que podem interferir no peso corporal, a fim de auxiliar os profissionais na orientação de indivíduos portadoresda doença. Para tanto, foi realizada uma revisão integrativa nas bases de dados: SciELO, Scholar Google, PubMed, BVS e Portal de Periódicos Capes, a partir de trabalhos publicados entre 2010 e 2019. Observou-se que as biguanidas, os inibidores da α-glicosidade, os análogos de incretinas, os análogos da amilina e os inibidores do cotransportador de sódio/glicose acarretam perda de peso. Por outro lado, as sulfonilureias, as meglitinidas e as glitazonas conferem ganho de peso ao paciente. Sendo assim, a prescrição desses fármacos deve ser feita de maneira individualizada

Obesity has been growing significantly worldwide, representing a risk for the increase of type 2 diabetes mellitus. The pharmacotherapy of diabetes can alter body weight, aiding in weight loss as well as in weight gain. Therefore, the objective of the present study was to review studies on the drugs used in type 2 diabetes that may interfere with body weight, in order to assist professionals in guiding individuals with diabetes. For this, an integrative review was performed in the SciELO, Scholar Google, PubMed, VHL, and Portal of Capes journals databases, considering works published between 2010 and 2019. We observed that biguanides, α-glucosity inhibitors, analogues of incretins, amylin analogues, and sodium / glucose co-transporter inhibitors lead to weight loss. On the other hand, sulphonylureas, meglitinides, and glitazones confer weight gain. Therefore, the prescription of these drugs should be made in an individualized fashion

Effectiveness of triple therapy with dapagliflozin add-on to dual therapy over 52 weeks in patients with uncontrolled type 2 diabetes mellitus in a centre of high complexity, Cali-Colombia

ABSTRACT Objectives: To evaluate the effectiveness of adding dapagliflozin as an intensification strategy for the treatment of patients with uncontrolled type 2 diabetes mellitus (T2DM). Materials and methods: A historical cohort study was conducted in 123 adult patients over 18 years old who were diagnosed with uncontrolled T2DM, who received dapagliflozin add-on to their dual base treatment: metformin plus glibenclamide (n = 32), metformin plus saxagliptin (n = 29), metformin plus exenatide (n = 28), or metformin plus insulin (n = 34). The endpoints were evaluated using analysis of variance. Results: All the patients completed a 52-week follow-up. Overall, 52.85% of patients were female, the Hispanic population represented the largest proportion of patients in all groups (60.98%), and the mean ± SD patient age and body weight were 55.05 ± 7.58 years and 83.55 ± 9.65 kg, respectively. The mean ± SD duration of T2DM, glycated hemoglobin (HbA1c), and fasting plasma glucose (FPG) were 5.93 ± 2.98 years, 8.1 ± 0.53%, and 166.03 ± 26.80 mg/dL, respectively. The grand mean changes of HbA1c, FPG, body weight and blood pressure showed a decreasing trend during the study period and it was statistically significant in all groups (p-value = <0.001). The proportion of patients achieving HbA1c target (<7%) was highest in the group that used a dapagliflozin add-on to metformin plus saxagliptin. Conclusion: The addition of dapagliflozin as an alternative for intensification of dual therapy consistently improved, not only FPG and HbA1c, but also body weight and blood pressure, with statistically significant results.

Investigation of the possible protective effect of Smilax fluminensis steud. leaf in mice subjected to oxidative stress by paracetamol

Paracetamol (PCM) is a drug widely used by the population as an antipyretic and analgesic. If administered in high doses it can cause liver damage, leading to hepatoxicity. The genus Smilax, found in temperate and tropical regions, is traditionally used by the population through the extract of leaves and roots for several conditions, such as in the treatment of syphilis, diabetes, asthma and as a diuretic action. Through this, Smilax fluminensis leaf extracts were used to evaluate the protective effect against oxidative stress induced by a high dose of PCM in mice that received the drug and after receiving treatment with crude extract and fractions. Plasma analysis was performed using as partate aminotransferase (AST), alanine aminotransferase (ALT), glucose, triglycerides and cholesterol, in addition to biochemical techniques such as catalase (CAT), glutathione-S-transferase (GST), reduced glutathione (GSH), ascorbic acid (ASA), substances reactive to thiobarbituric acid (TBARS) and carbonylated proteins (CARBONYL) of liver, brain and kidneys. Fraction 1 of the extract was the most promising, decreasing the plasma levels of AST and ALT, the levels of CAT and GST of the liver, together with GSH and in the renal and brain tissue there was a decrease in carbonylated proteins (PCM + F1 versus PCM ). Besides, fraction 1 proved to be hypoglycemic and hypocholesterolemic. It is concluded that fraction 1 of Smilax fluminensis leaves has good antioxidant activity in the face of the damage caused by the high dose of paracetamol.

Control glicémico perioperatorio / Perioperatory glycemic control

Diabetes is the most common endocrinopathy, in 2014, 8.6% of the population suffered from diabetes, and it was responsible for at least 3.7 million deaths per year. It is estimated that by that by 2050 more than 30% of the population will have this disease. In cardiovascular surgery, it is described that 5.2% of patients are undiagnosed diabetics and this rises to 10% -28% in non-cardiac surgeries. The adverse results are markedly high in those patients with poor glycemic control including an increase of more than 50% in mortality, as well as an increase in respiratory infections, surgical site infection, urinary infection, heart attack and acute kidney injury among others. During the preoperative period of patients with diabetes, it is important to review glycemic control and its current treatment, in addition to providing the patient instructions on how to adjust medications. Intraoperatively, any condition that leads to an uncontrolled increase in surgical stress must be controlled, since this in turn generates hyperglycemia. Knowledge of insulins, their pharmacology and schedules is essential to maintain blood glucose intraoperatively in normal ranges. Different practical algorithms are proposed for the correct and safe management of hyperglycemia in the perioperative period. All care should be continued in the postoperative period defining the continuity of the insulin therapies established and the postoperative care of the patient.

La diabetes es la endocrinopatía más común, en 2014, el 8,6% de la población padecía diabetes siendo responsable de 3,7 millones de muertes por año. Se estima que para el 2050 más del 30% de la población tendrá diabetes. En cirugía cardiovascular el 5,2% de los pacientes son diabéticos no diagnosticados, cifra que aumenta hasta 10%-28% en cirugías no cardíacas. Los resultados adversos son marcadamente elevados en aquellos pacientes con mal control incluyendo un aumento del 50% en la mortalidad, así mismo, incremento de infecciones respiratorias, infección del sitio quirúrgico, infección urinaria, infarto agudo de miocardio y lesión renal aguda, entre otros. Durante el preoperatorio de pacientes con diabetes, es importante revisar el control glucémico y su tratamiento, además de proporcionar al paciente instrucciones por escrito sobre cómo ajustarlo. En el intraoperatorio se debe controlar cualquier condición que lleve a un aumento del estrés quirúrgico pues este a su vez genera hiperglucemia. Es fundamental el conocimiento de las insulinas, su farmacología y esquemas para mantener glucemias en el intraoperatorio en rangos normales. Se proponen diferentes algoritmos prácticos para el correcto y seguro manejo de la hiperglucemia en el perioperatorio. La atención debe continuarse en el posoperatorio definiendo continuidad de terapias insulínicas instauradas y el adecuado cuidado del paciente.

Analysis on drug transporters-mediated interaction between drugs and metformin / 中国基层医药

Objective:To investigate the potential drug interactions of outpatient prescriptions containing metformin combined with other drugs from the perspective of drug transporters.Methods:The prescriptions containing metformin that were used in the Outpatient Department of Hainan General Hospital, China between July and December 2019 were collected. The potential interaction between drugs and metformin used in the prescriptions was analyzed according to drug instructions, Drugbank, PubMed databases.Results:A total of 15 568 outpatient prescriptions containing metformin were collected, including 9 146 prescriptions for male patients and 6 422 prescriptions for female patients. A total of 14 902 prescriptions contained combined medication. The drugs used in combination included other hypoglycemic drugs, antiplatelet drugs, antihypertensive drugs, lipid-lowering drugs, and neuroprotective drugs. The drug transporters including aspirin, atorvastatin calcium, repaglinide, bisoprolol, metoprolol and clopidogrel had a potential interaction with metformin. There were 11 614 prescriptions containing drug transporters and metformin, including 5 938 prescriptions inhibiting organic cation transporter 1 and 5676 prescriptions inhibiting organic cation transporter 2.Conclusion:There is no incompatibility between the outpatient prescriptions containing metformin and the commonly used drugs for chronic diseases, but the outpatient doctors do not have enough knowledge about dose adjustment caused by potential interaction.
