Monitoreo continuo de glucosa: indicaciones, interpretación de datos y toma de decisiones terapéuticas. Recomendaciones de expertos / Continuous glucose monitoring: indications, data interpretation and making therapeutic decisions. Expert recommendations

Las herramientas para evaluar el grado de control glucémico se modificaron últimamente. La emoglobina glicosilada (HbA1c), parámetro de referencia (gold standard), refleja el control glucémico de los últimos tres meses de manera retrospectiva, sin expresar la variabilidad glucémica. El automonitoreo glucémico capilar (AGC) brinda información inmediata y prospectiva, pero dispone de pocos datos glucémicos para generar promedios y desviaciones estándares representativas. No detecta tendencias y tiene limitaciones para obtener datos nocturnos o durante la actividad física. Es invasivo y muchas veces rechazado. Contrariamente, el monitoreo continuo de glucosa (MCG) mide la glucosa instantáneamente, y muestra sus tendencias y su variabilidad en forma continua, incorporando nuevas métricas de control. Mediante el perfil ambulatorio de glucosa (PAG) se analizan los patrones del control glucémico durante el sueño, los ayunos prolongados, la actividad física y las intercurrencias, expresándolos como curvas con sus desviaciones estándar durante períodos de horas (8 a 24 horas) o días (7, 14, 30 y 90 días). El PAG contiene las siguientes métricas: porcentaje de tiempo en rango TIR (del inglés, time in range), porcentaje de tiempo por encima del rango TAR (del inglés, time above range), porcentaje de tiempo por debajo del rango o hipoglucemia TBR (del inglés, time below range) y coeficiente de variabilidad (%CV). La información continua permite tomar decisiones inmediatas, ya sea con la ingesta de carbohidratos o con la aplicación de insulina. El MCG con terapéuticas insulínicas inyectables (TII) o bomba portable de insulina (BPI) es una herramienta muy útil y complementaria para el tratamiento de la diabetes mellitus tipo 1 (DM1) y la DM2 en la insulinoterapia. Su utilización se asoció con descensos significativos en la HbA1c, disminución de la variabilidad glucémica, reducción de las hipoglucemias totales y nocturnas, y mejoría de la calidad de vida en estos pacientes. Nuestro propósito como grupo de expertos es generar una guía práctica para regular la implementación del MCG.

The tools to assess the degree of glycemic control were modified lately. Glycosylated hemoglobin (HbA1c), the gold standard, reflects the glycemic control of the last 3 months retrospectively, without expressing glycemic variability. Selfblood glucose monitoring (SBGM) provides immediate and prospective information, but has little glycemic data to generate representative averages and standard deviations. It does not detect trends and has limitations to obtain nocturnal data or during physical activity. It is invasive and often rejected. On the contrary, continuous glucose monitoring (CGM), allows to measure glucose instantly, shows your trends and variability continuously, incorporating new control metrics. The ambulatory glucose profile (AGP) analyzes the patterns of glycemic control during sleep, prolonged fasting, physical activity and intercurrences, expressing them as curves with their standard deviations during periods of hours (8 to 24 hours) or days (7, 14, 30 and 90 days). The AGP contains the following metrics: percentage time in range (TIR), percentage time above range mg/dl (TAR), percentage time below range or hypoglycemia (TBR) and coefficient of variation (%CV). CGM with IIT or continuous subcutaneous insulin infusion (CSII), is a very useful and complementary tool for the treatment of DM1 and DM2 in insulin therapy. Its use was associated with significant decreases in HbA1c, decreased glycemic variability, reduction of total and nocturnal hypoglycemia and improvement of the quality of life in these patients. Our aim as a group of experts is to generate a practical guide to regulate the implementation of the CGM.

Effect of intensive insulin therapy on high mobility group box-1/nuclear factor-κB pathway in severe traumatic brain injury patient with stress hyperglycemia / 中华危重病急救医学

To explore the effect of intensive insulin therapy (IIT) on high mobility group box-1/nuclear factor-κB (HMGB1/NF-κB) signaling pathway in severe traumatic brain injury (sTBI) patient with stress hyperglycemia. Methods Sixty-one sTBI patients with stress hyperglycemia [Glasgow coma scale (GCS) ≤ 8, three times of random blood glucose levels > 11.1 mmoL/L, glycosylated hemoglobin (HbA1c) < 0.065] admitted to the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from July 2015 to October 2017 were enrolled. Patients were divided into IIT group (29 cases, keeping blood glucose at 4.4-7.8 mmol/L) and conventional glycemic therapy (CGT) group (32 cases, keeping blood glucose at 7.8-12.2 mmo/L) according to the random number table method. Before treatment and 1, 7 and 14 days after treatment, the levels of plasma HMGB1 and tumor necrosis factor-α (TNF-α) were measured by enzyme linked immunosorbent assay (ELISA); C-reactive protein (CRP) was determined by automatic biochemical analyzer, and NF-κB p65 gene expression in peripheral blood mononuclear cells was detected by real-time quantitative polymerase chain reaction (PCR). Results Nine patients were withdrawn from the observation because the 4 consecutive blood glucose monitoring did not reach the target value, combined with severe infection, or abandoned the treatment with serious brain damage. Finally, 52 patients were enrolled in the analysis, including 28 in CGT group and 24 in IIT group. The levels of plasma HMGB1, TNF-α, CRP and the expression of NF-κB gene in monocytes of the two groups at 1 day after treatment were significantly higher than those before treatment, and reached the peak value, then gradually decreased. After 7 days of treatment, they were significantly lower than 1 day. The levels of plasma CRP and TNF-α in the IIT group were significantly lower than those in the CGT group [CRP (mg/L): 36.7±4.4 vs. 45.1±6.1, TNF-α (ng/L): 42.4±9.7 vs. 53.2±9.1, both P < 0.05], the level of HMGB1 in plasma and the expression of NF-κB p65 in monocytes were significantly lower than those in the CGT group after 14 days of treatment [HMGB1 (μg/L): 60.1±8.7 vs. 80.5±9.1, NF-κB p65 (ΔCt): 35.8±8.5 vs. 53.5±7.3, both P < 0.05]. Conclusion IIT inhibits the inflammatory response in sTBI patients with stress hyperglycemia through HMGB1/NF-κB pathway.

Objective To explore the influence of case management on short-term intensive insulin therapy effect,including treatment compliance,safety and glucose metabolic index in newly diagnosed type 2 diabetic patients in outpatient clinic. Methods A total of 100 newly diagnosed type 2 diabetic patients in outpatient clinic were enrolled in this study and randomly divided into 2 groups:intervention group (n=52)and control group (Con,n = 48 ). The intervention group received standard insulin injection case management provided by a team composed of doctors and nurse case manager. The control group received routine insulin injection education in outpatient. Attitudes and compliance of insulin treatment,incidence of hypoglycemia,fasting blood glucose (FBG) and glycated haemoglobin A1c (HbA1 c ) were compared between the two groups at baseline and after 3 months follow up. Results After intervention,the total score and scores by dimension of insulin treatment attitude were higher in intervention group than in Con group[(76.30 ± 4.06 )vs (60.53 ± 3.18 )score,P 0.05),although without statistical difference. FBG and HbA1 c were all lower in intervention group than in Con group [(6.79 ± 1.41 )vs (7.51±1.15)mmol/L,(6.62±0.69)％ vs (7.15±0.75)％,P <0.05]. Conclusion Case management could effectively improve the insulin treatment attitude and compliance,and then optimize glycemic control innewly diagnosed type 2 diabetic patients treated with short-term intensive insulin therapy in outpatient clinic.

Glycemic control and changes of inflammatory factors in severe sepsis patients and their clinical significance / 中华急诊医学杂志

Objective To investigate glycemic control,changes of inflammatory factors and their clinical significance in severe sepsis patients.Methods One hundred and three severe sepsis patients with abnormal hyperglycemia were randomly divided into the two groups and receive intensive insulin therapy (IIT) and conventional insulin therapy (CIT) respectively.According to glycosylated hemoglobin level,the two groups were further divided into stress hyperglycaemia and diabetes mellitus subgroups.The mortality and incidence of hypoglycemia were compared between the groups and subgroups.Enzyme linked immunosorbent assay was used to detect TNF-α,IL-6 levels before treatment,3 and 7 days after treatment.Results In IIT group,the mortality in diabetes mellitus subgroup was significantly higher than that in stress hyperglycaemia subgroup (66.7％ vs.30.8％,P ＜ 0.05),while the mortality in stress hyperglycaemia subgroup significantly higher than that in diabetes mellitus subgroup (54.1％ vs.25.0％,P ＜ 0.05) in CIT group.Multivariate Logistic regression analysis revealed IIT increased the risk for death in diabetes mellitus subgroup (OR =1.221,95％ CI:1.075-1.434),while decreased the risk for death in stress hyperglycaemia subgroup (OR =0.872,95％ CI:0.714-0.975).The incidence of hypoglycemia was significantly higher in IIT group than that in CIT group (13.7％ vs.1.9％,P ＜0.05).Before treatment,the levels of TNF-α,IL-6 in stress hyperglycaemia patients were significantly higher than those in diabetes mellitus patients.After 7 day treatment,The levels of TNF-α,IL-6 decreased significantly in stress hyperglycaemia patients (P ＜ 0.01),and decreased more significantly in IIT group than that in CIT group.Conclusion Severe sepsis patients with stress hyperglycaemia can attain better glycemia control and inhibition of inflammatory factors,and clinical benefit from IIT.

Features of lipid ratios in patients with newly diagnosed T2DM and effects of intensive insulin treatment on them / 实用医学杂志

Objective To investigate the features of lipid ratios in patients with newly diagnosed T2DM, and the effects of intensive insulin treatment on them. Methods 90 patients with newly diagnosed T2DM and 58 matched people with normal glucose were enrolled to assess height,weight,waist circumference,blood glucose and lipid profiles. BMI,TC/HDL-C,TG/HDL-C,log(TG/HDL-C),LDL-C/HDL-C,HOMA-B and HOMA-IR were calculated respectively. All the patients received the continuous subcutaneous insulin infusion with insulin pump. The treatment continued for more 10~14 days after blood glucose reached the standard. All the above indi-cators were reexamined after treatment. Results Dyslipidemia in patients with newly diagnosed T2DM mainly showed as hypertriglyceridemia and decreased HDL-C compared to the control group(P<0.05). TC/HDL-C,TG/HDL-C,log(TG/HDL-C)and LDL-C/HDL-C significantly increased in these patients(P<0.01). After short-term intensive insulin therapy,all lipid ratios were significantly decreased and the changes of lipid ratios were positively correlated with the change of HOMA-IR(P<0.05). Conclusion Short-term intensive insulin therapy for patients with newly diagnosed type 2 diabetes can significantly lower the lipid ratios related to HDL-C. The effects may be closely related to improvement of insulin resistance.

Intensive Insulin Therapy in Type 1 Diabetes / 임상당뇨병

The Epidemiology of Diabetes Interventions and Complications study, a prospective observational follow-up of the Diabetes Control and Complications Trial cohort, reported persistent benefits for micro- and macro-vascular complication in type 1 diabetes mellitus with intensive insulin therapy. It is the standard of care for most patients with type 1 diabetes. There are two modalities: continuous subcutaneous insulin infusion (CSII), so called insulin pump, and multiple dose of insulin. Both shows similar effects in frequency of severe hypoglycemia and progression of microvascular disease, but CSII provides slightly better in glycemic control. An important aspect of intensive insulin therapy is educating patients about basal insulin, and carbohydrate/insulin ratio, sensitivity index, the coordination of meals, activity, stress, and hormonal changes with frequent monitoring of blood glucose levels during pregnancy. It is important to identify and resolve emotional and attitudinal barriers of the patient and family for improving glycemic control during intensive diabetes management.

Rediscovery the Effect of Intensive Insulin Therapy on Stress Hyperglycemia in Critical Trauma Patients / 天津医药

Objective To investigate the effect and safety of intensive insulin therapy on patients who had stress hy-perglycemia induced by critical trauma, when different blood glucose was aimed in surgery intensive care unit (SICU). Methods We retrospectively analyzed SICU patients who were admitted between 2010.1-2012.7 with admission blood glucose and 30 minutes blood glucose both over 11.1 mmol/L ,and without known history of diabetes. In total, 153 pa-tients were set into three groups according to their target blood glucose:intensive insulin therapy (IIT) group with target blood glucose of 4.0-6.1 mmol/L;NICE SUGAR (NST) group with target blood glucose of 6.2-8.3 mmol/L;conventional in-sulin therapy(CIT)group with target blood glucose of 9.9-11.1 mmol/L. Each group had 51 patients. To collect data from these three groups of patients,we compared daily insulin doses , hypoglycemia incidence, final blood glucose, APACHEⅡscores upon discharging from ICU, time of the ventilatory support, length of staying in ICU, morbidity and mortality rate. Results Comparing these three groups, daily insulin dosage and hypoglycemia incidence, were significantly lower in NST and CIT group than in IIT group. Daily insulin dosage was higher in NST group than in CIT group;no significant difference of hypoglycemia incidence was shown between NST group and CIT group. The final blood glucose was lowest in IIT group and highest in CIT group (P＜0.05). APACHE II score was 9.3±7.5 upon discharge from ICU in NST group. Ventilation time and duration of ICU admission both were shortest in NST group but show no significant difference between IIT and CIT group . No significant difference of complicate incidence and mortality rate was indicated among all three groups. Conclusion In patient with stress hyperglycemia induced by critical trauma,maintaining the patients’final blood glucose between 6.2-8.3 mmol/L can effectively control the stress hyperglycemia,improve prognosis and reduce the mortality of hypoglycemia.

Intensive insulin therapy, together with carbohydrate counting, is currently considered the best therapeutic strategy for the management of type 1 diabetes mellitus (DM1). However, goals of glycemic control proposed by consensus are still difficult to achieve with this therapy,which has also been associated with weight gain and increased hypoglycemia. Objective: To describe a population of patients with DM1, who were treated with intensive insulin therapy. Material and methods: This descriptive, cross-sectional study included type 1 diabetics who underwent intensive insulin therapy and used different levels of the carbohydrate counting method. All these patients were attending the Type 1 Diabetes Section of the Nutrition Division at the“José de San Martín” Clinical Hospital and they made at least one follow-up visit between July 2011 and July 2012.

Intensive insulin therapy in severe acute pancreatitis: a meta-analysis and systematic review / Terapia intensiva de insulina en la pancreatitis aguda severa: meta-análisis y revisión sistemática

OBJECTIVE: To assess the effect of intensive insulin therapy on outcomes of patients with severe acute pancreatitis. METHODS: Relevant literatures cited in these electronic databases: Medline, Chinese Biomedical Literature Database, China National Knowledge Infrastructure (CNKI) database, and Excerpta Medical database (Embase) were systematically searched for randomized controlled trials (RCTs) in which intensive insulin therapy was used in severe acute pancreatitis. Length of hospitalization, acute physiology and chronic health evaluation II (APACHE II) score, incidence of complications, and adverse effects were recorded for statistical analysis. The methodological quality of the eligible studies was assessed by Jadad scale. The results were analysed by Revman 4.3 software. RESULTS: Three studies, which included a total of 118 cases, were finally reviewed. The methodological quality of the trials varied substantially. In patients with severe acute pancreatitis, intensive insulin therapy was associated with shorter length of hospitalization (weighted mean difference (WMD) = -12.13, 95% confidence interval (CI) [-15.48,8.78], p > 0.00001) and lower APACHE II score after 72 hours treatment (WMD = -3.80, 95% CI [-4.88,2.72], p> 0.00001). One study reported insulin-related adverse event. CONCLUSION: In patients with severe acute pancreatitis, intensive insulin therapy could relieve the patient's condition earlier and shorten the length of hospitalization without serious adverse effect.

OBJETIVO: Evaluar el efecto de la terapia intensiva de insulina en la evolución clínica de los pacientes afligidos de pancreatitis aguda severa. MÉTODOS: La literatura pertinente citada a partir de las siguientes bases electrónicas de datos: Medline, Base de datos de literatura biomédica china, Base de datos de la infraestructura nacional china de conocimientos (CNKI), y la Excerpta Medical Database (Embase). Todas estas bases de datos fueron investigadas sistemáticamente en busca ensayos controlados aleatorios (RCT), en los cuales la terapia de insulina intensiva se usó en la pancreatitis aguda severa. El tiempo de hospitalización, la fisiología aguda, y la puntuación de la evaluación de salud crónica II (APACHE II), la incidencia de complicaciones, así como los efectos adversos, fueron registrados para el análisis estadístico. La calidad metodológica de los estudios elegibles fue evaluada mediante la escala de Jadad. Los resultados se analizaron mediante el software Revman 4.3. RESULTADOS: Finalmente se examinaron tres estudios que incluyeron un total de 118 casos. La calidad metodológica de los ensayos varió sustancialmente. En los pacientes con pancreatitis aguda severa, la terapia de insulina intensiva estuvo asociada con una estadía hospitalaria más corta (diferencia media ponderada WMD = -12.13, 95% intervalo de confianza (CI) [-15.48, 8.78], p < 0.00001) y una puntuación APACHE II más baja después de 72 horas de tratamiento (WMD = -3.80, 95% CI [-4.88, 2.72], p < 0.00001). Un estudio reportó eventos adversos relacionados con la insulina. CONCLUSIÓN: En los pacientes con pancreatitis aguda severa, la terapia intensiva de insulina podría aliviar la condición del paciente más rápidamente, y acortar el tiempo de hospitalización sin serios efectos adversos.
