ABSTRACT
Diabetes Mellitus (DM) and obesity are a public health problem in Chile. Bariatric surgery is the most effective treatment alternative to achieve a significant and sustained weight reduction in patients with morbid obesity. The results of controlled clinical trials indicate that, compared to medical treatment, surgery for obese patients with DM2 allows a better control of blood glucose and cardiovascular risk factors, reduces the need for medications and increases the likelihood for remission. Consensus conferences and clinical practice guidelines support bariatric surgery as an option to treat DM2 in Class III Obesity (Body Mass Index (BMI) > 40) regardless of the glycemic control and the complexity of pharmacological treatment and in Class II Obesity (BMI 35-39,9) with inadequate glycemic control despite optimal pharmacological treatment and lifestyle. However, surgical indication for patients with DM2 and BMI between 30-34.9, the most prevalent sub-group, is only suggested. The Chilean Societies of Endocrinology and Diabetes and of Bariatric and Metabolic Surgery decided to generate a consensus regarding the importance of other factors related to DM2 that would allow a better selection of candidates for surgery, particularly when weight does not constitute an indication. Considering the national reality, we also need a statement regarding the selection and characteristics of the surgical procedure as well as the role of the diabetologist in the multidisciplinary team.

ABSTRACT To understand the status of prediabetes diagnosis and treatment in Latin America and to evaluate the use of metformin for diabetes prevention in this context. A panel of 15 diabetes experts from seven countries in Latin America met on 14 - 15 August 2014 in Lima, Peru, to review the available literature, discuss the role of prediabetes in type 2 diabetes mellitus and cardiovascular disease, analyze collected information, and make conclusions for prediabetes diagnosis and treatment in Latin America. Prediabetes diagnosis, screening, and treatment, including lifestyle changes, pharmacological treatment, and cost-effectiveness were discussed. Five resulting statements were issued for Latin America: prediabetes is a clinical and public health problem; health care systems do not currently diagnose/treat prediabetes; use of prediabetes risk detection tools are needed region-wide; treatment includes lifestyle changes, multidisciplinary education, and metformin; and registries of patient records and further studies should be supported. The expert panel concluded that in Latin America, preventive treatment through lifestyle changes and metformin are cost-effective interventions. It is important to improve prediabetes identification and management at the primary care level.(AU)
RESUMEN Comprender el estado del diagnóstico y el tratamiento de la prediabetes en América Latina y evaluar el uso de la metformina para la prevención de la diabetes en este contexto. Un panel de 15 expertos en diabetes de siete países de América Latina se reunió del 14 al 15 de agosto de 2014 en Lima, Perú, para revisar la literatura disponible, discutir el papel de la prediabetes en la diabetes mellitus tipo 2 y la enfermedad cardiovascular, analizar la información recolectada y formular conclusiones para el diagnóstico y el tratamiento de la prediabetes en América Latina. Se analizaron el diagnóstico, el tamizaje y el tratamiento de la prediabetes, inclusive los cambios en el estilo de vida, el tratamiento farmacológico y la relación costo-eficacia. Se emitieron cinco conclusiones para América Latina: la prediabetes es un problema clínico y de salud pública; los sistemas de atención de la salud actualmente no diagnostican o no tratan la prediabetes; el uso de herramientas de detección del riesgo de prediabetes es necesario en toda la región; el tratamiento incluye cambios en el estilo de vida, educación multidisciplinaria y metformina; y se debe brindar apoyo para llevar registros de historias clínicas y realizar estudios adicionales. El panel de expertos concluyó que en América Latina el tratamiento preventivo basado en cambios en el estilo de vida y administración de metformina son intervenciones eficaces en relación al costo. Es importante mejorar la identificación y el manejo de la prediabetes en el nivel de atención primaria.(AU)

Um painel de 15 especialistas em diabetes de sete países da América Latina reuniu-se de 14 a 15 de agosto de 2014 em Lima, Peru, para analisar a literatura disponível, discutir o papel do prediabetes em diabetes mellitus tipo 2 e doenças cardiovasculares, analisar informações coletadas e fazer conclusões para o diagnóstico e tratamento do prediabetes na América Latina. O diagnóstico, rastreio e tratamento pré-diabetes, incluindo mudanças de estilo de vida, tratamento farmacológico e custo-efetividade foram discutidos. Foram emitidas cinco conclusões resultantes para a América Latina: o prediabetes é um problema clínico e de saúde pública; os sistemas de saúde atualmente não diagnosticam/tratam prediabetes; o uso de ferramentas de detecção de risco de prediabetes é necessário em toda a região; o tratamento inclui mudanças de estilo de vida, educação multidisciplinar e metformina; e devem ser suportados registros de pacientes e outros estudos. O painel de especialistas concluiu que na América Latina, o tratamento preventivo através de mudanças de estilo de vida e metformina são intervenções efetivas em relação ao custo. É importante melhorar a identificação e gestão do prediabetes no nível de atenção primária.(AU)

Insulin resistance is a prevalent condition commonly associated with unhealthy lifestyles. It affects several metabolic pathways, increasing risk of abnormalities at different organ levels. Thus, diverse medical specialties should be involved in its diagnosis and treatment. With the purpose of unifying criteria about this condition, a scientific-based consensus was elaborated. A questionnaire including the most important topics such as cardio-metabolic risk, non-alcoholic fatty liver disease and polycystic ovary syndrome, was designed and sent to national experts. When no agreement among them was achieved, the Delphi methodology was applied. The main conclusions reached are that clinical findings are critical for the diagnosis of insulin resistance, not being necessary blood testing. Acquisition of a healthy lifestyle is the most important therapeutic tool. Insulin-sensitizing drugs should be prescribed to individuals at high risk of disease according to clinically validated outcomes. There are specific recommendations for pregnant women, children, adolescents and older people.
