Background: Information regarding diagnosis, treatment, and follow-up of patients with type 1 diabetes (PWT1D) in Mexico is limited. We developed an on-line platform Registro Nacional de Pacientes con Diabetes Tipo 1 (RENACED-DT1). Objective: The objective of the study was to describe the characteristics and healthcare of PWT1D registered in RENACED-DT1. Methods: Analyses of 965 PWT1D from July 2014 to January 2018 in different endocrinology clinics around Mexico. Results: Sixty-one percent were female with median age of 21 years, age at diagnosis 11 years, and disease duration at inclusion 8.2 years. Treatment regimen was basal-bolus in 61% and insulin-pumps in 21% (mainly in the private sector); 33.3% with self-monitoring of blood-glucose (SMBG) ≥4 times/day. Mean HbA1c at last follow-up was 8.7 ± 2.1% (72±23 mmol/mol), 18% had HbA1c < 7% (53 mmol/mol), and 35% > 9% (75 mmol/mol). SMBG ≥ 4 times/day was associated with HbA1c < 7%. Time since diagnosis > 10 years, female sex, BMI ≥ 30 kg/m2, SMBG < 4 times/day, and any hypoglycemia were associated with microvascular complications (p < 0.05). Conclusions: Percentage of patients achieving HbA1c < 7% is low; increased blood glucose monitoring is associated with better glycemic control. The achievement of optimal glycemic control must be increased to reduce the incidence of chronic complications and improve quality of life in PWT1D.

Abstract: Objective: To evaluate efficacy and safety of 60 mg and 120 mg Fimasartan (FMS) alone or combined with 12.5 mg hydrochlorothiazide (HCTZ) in a Mexican population. Methods: A six month, treat-to-target, open study was conducted on subjects with grade 1-2 hypertension. The subjects were initially treated with 60 mg FMS once daily. In week 8, those with Diastolic Blood Pressure (DBP) <90 mmHg continued on the same FMS dose during the rest of the study, while those with DBP ≥90 mmHg were randomised to either 120 mg FMS or 60 mg FMS + 12.5 mg HCTZ once daily. In week 12, randomised subjects with DBP ≥90 mmHg received 120 mg FMS + 12.5 mg HCTZ, while those achieving target continued with their assigned treatment until the end of the study. Results: FMS 60 mg (n = 272) decreased both DBP and Systolic Blood Pressure (SBP) by 11.3 ± 8.9 (p<.0001) and 16.0 ± 14.1 (p<.0001) mmHg, respectively, with 75.4% of subjects reaching the treatment target. Subjects assigned to FMS 120 mg, FMS 60 mg + HCTZ 12.5 mg, or FMS 120 mg + HCTZ 12.5 mg once daily, showed significant reductions in DBP and SBP with their assigned treatment. At the end of the study, 237/272 subjects (87.1%) achieved a DBP < 90 mmHg and an SBP<140 mmHg. The most frequently reported adverse reactions included headache (3.7%), dry mouth (1.1%), transient liver enzyme increase (1.1%), and dizziness (0.7%). Conclusion: Fimasartan is safe and effective in Mexican subjects with grade 1-2 essential hypertension.

Resumen: Objetivo: Evaluar la eficacia y la seguridad de 60 y 120 mg de fimasartán (FMS) solo o combinado con 12.5 mg de hidroclorotiazida (HCTZ) en población mexicana. Métodos: Estudio abierto, de 24 semanas, con tratamiento escalado hasta el objetivo terapéutico en sujetos hipertensos grados 1–2. Tratamiento inicial: FMS 60 mg una vez al día; en la semana 8, los sujetos con presión arterial diastólica (PAD) <90 mmHg mantuvieron su tratamiento inicial durante el estudio, mientras que los sujetos con PAD ≥90 mmHg fueron aleatorizados a 120 mg de FMS o a 60 mg de FMS + 12.5 mg de HCTZ. En la semana 12, los sujetos aleatorizados con PAD ≥90 mmHg recibieron 120 mg de FMS + 12.5 mg de HCTZ; quienes alcanzaron el objetivo terapéutico mantuvieron su tratamiento asignado hasta finalizar el estudio. Resultados: FMS 60 mg (n = 272) disminuyó la PAD y la presión arterial sistólica (PAS) en 11.3 ± 8.9 (p < 0.0001) y 16.0 ± 14.1 (p < 0.0001) mmHg, respectivamente, con logro del objetivo de tratamiento en el 75.4% de los sujetos. Los sujetos asignados a 120 mg de FMS, a 60 mg de FMS + 12.5 mg de HCTZ 12.5 y a 120 mg de FMS + 12.5 mg de HCTZ mostraron reducciones significativas de PAD y PAS; al final del estudio, 237/272 sujetos (87.1%) lograron PAD <90 y PAS <140 mmHg. Las reacciones adversas más frecuentemente reportadas fueron: cefalea (3.7%), boca seca (1.1%), incremento de enzimas hepáticas (1.1%) y mareo (0.7%). Conclusión: FMS es seguro y eficaz en sujetos mexicanos con hipertensión esencial de grados 1–2.

RESUMO Entender o estado do diagnóstico e tratamento do prediabetes na América Latina e avaliar o uso de metformina para prevenção de diabetes neste contexto. 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.

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.

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.
