RESUMO

Aim: To compare the safety in terms of hypoglycemic events and continuous glucose monitoring (CGM) metrics during aerobic exercise (AE) of using temporary target (TT) versus suspension of insulin infusion (SII) in adults with type 1 diabetes (T1D) using advanced hybrid closed-loop systems. Methods: This was a randomized crossover clinical trial. Two moderate-intensity AE sessions were performed, one with TT and one with SII. Hypoglycemic events and CGM metrics were analyzed during the immediate (baseline to 59 min), early (60 min to 6 h), and late (6 to 36 h) post-exercise phases. Results: In total, 33 patients were analyzed (44.6 ± 13.8 years), basal time in range (%TIR 70-180 mg/dL) was 79.4 ± 12%, and time below range (%TBR) <70 mg/dL was 1.8 ± 1.7% and %TBR <54 mg/dL was 0.5 ± 0.9%. No difference was found in the number of hypoglycemic events, %TBR <70 mg/dL and %TBR <54 mg/dL between TT and SII. Differences were found in the early phase, with better values when using TT for %TIR 70-180 mg/dL (83.0 vs. 65.3, P = 0.005), time in tight range (%TITR 70-140 mg/dL) (56.3 vs. 41.5, P = 0.04), and time above range (%TAR >180 mg/dL) (15.3 vs. 31.8, P = 0.01). In the diurnal period, again %TIR was better for TT use (82.1 vs. 73.1, P = 0.02) and %TAR (15.0 vs. 22.96, P = 0.04). No significant differences were found in the CGM metrics during the different phases of AE. Conclusion: Our data appear to show that the use of TT compared with SII is equally safe in all phases of AE. However, the use of TT allows for a better glycemic profile in the early phase of exercise.

RESUMO

AIM: Gestational diabetes (GD) is a global health concern with significant implications for maternal and neonatal outcomes. This study investigates the association between early GD (eGD) diagnosis (<24 weeks), pharmacotherapy requirements and adverse neonatal outcomes. MATERIALS AND METHODS: A cohort of 369 pregnant women underwent a 75-g oral glucose tolerance test. Maternal variables, pharmacotherapy prescriptions and neonatal outcomes were analysed employing t-tests, χ2 tests, and logistic regression. A p < .05 was considered significant. RESULTS: Early GD increased the odds of neonatal hypoglycaemia [odds ratio (OR): 18.57, p = .013] and respiratory distress syndrome (OR: 4.75, p = .034). Nutritional therapy prescription by an accredited nutritionist was the most common treatment in women diagnosed after 24 weeks, but those with eGD required more frequently specialized nutritional consulting + metformin to achieve glycaemic control (p = .027). eGD was associated with a higher requirement of nutritional therapy prescription + metformin (OR: 2.26, 95% confidence interval: 1.25-4.09, p = .007) and with maternal hyperglycaemia during the post-partum period at 2 h of the oral glucose tolerance test (OR: 1.03, 95% confidence interval: 1.02-1.13, p = .024). CONCLUSION: Timely diagnosis and personalized treatment of GD are desirable because an earlier presentation is related to a higher risk of adverse neonatal and maternal outcomes.

RESUMO

AIM: To provide updated efficacy and safety information for teplizumab in the treatment of Stage 3 type 1 diabetes mellitus (T1DM). MATERIALS AND METHODS: The PubMed, Embase and Cochrane databases were searched for randomized controlled trials (RCTs) comparing teplizumab to placebo for T1DM that reported any of the following outcomes: (1) C-peptide area under the curve (AUC); (2) glycated haemoglobin (HbA1c) levels; (3) insulin requirements; and (4) adverse events. Heterogeneity was examined with I2 statistics. p values <0.05 were taken to indicate statistical significance. The continuous endpoints were compared through the pooled mean difference (MD) and binary endpoints were assessed using risk ratios, both with 95% confidence intervals (CIs). Statistical analyses were performed using Review Manager Web software. RESULTS: Eight RCTs with 1052 patients (754 receiving teplizumab) were included. Teplizumab significantly increased the AUC of C-peptide levels at 6 (MD 0.10 nmol/L, 95% CI 0.05, 0.16), 12 (MD 0.13 nmol/L, 95% CI 0.06, 0.20), 18 (MD 0.18 nmol/L, 95% CI 0.09, 0.27) and 24 months (MD 0.16 nmol/L, 95% CI 0.02, 0.31), significantly reduced HbA1c levels at 6 (MD -0.57%, 95% CI -1.07, -0.08) and 12 months (MD -0.31%, 95% CI -0.59, -0.02), and significantly reduced insulin requirements at 6 (MD -0.12 U/kg, 95% CI -0.16, -0.08), 12 (MD -0.11 U/kg, 95% CI -0.15, -0.07), 18 (MD -0.17 U/kg, 95% CI -0.26, -0.09) and 24 months (MD -0.11 U/kg, 95% CI -0.22, -0.01). CONCLUSION: Teplizumab increases AUC of C-peptide levels and decreases HbA1c levels and insulin use, without raising serious adverse event risk.

RESUMO

Objective: To evaluate glycemic control according to the number of daily basal rates (BRs) in type 1 diabetes patients using continuous subcutaneous insulin infusion (CSII). Subjects and methods: Cross-sectional study of patients treated with an open-loop CSII for at least 6 months and using a flash glucose monitoring system. Patients were divided into 2 groups: group 1 (G1) and group 2 (G2), with ≤4 and >4 BRs/24h, respectively. The groups were compared regarding HbA1c, time in range (TIR), time above range (TAR), time below range (TBR), glucose management indicator (GMI), glucose variability and data related to hypoglycemia. Regression models were performed. Results: The study included 99 patients (n = 55 in G1; n = 44 in G2). Median (Interquartile range) overall age was 30 (17) years, with 19.5 (48) and 51 (77) months of CSII use, respectively. The median number of different BRs was 3 (2) for G1 and 6 (2) for G2. There were no differences concerning age, sex, educational stage, weight, and insulin analog used. G2 had longer disease duration, longer CSII use, and higher total basal daily dose/kg. No significant differences regarding HbA1c, median glucose, GMI, TIR, TAR, and CV were found. G2 patients had more hypoglycemia, more asymptomatic hypoglycemia, and higher TBR. After adjusting for potential confounders, G1 maintained a lower risk of asymptomatic hypoglycemia. Conclusion: Programming open-loop CSII devices with more than 4 BRs does not improve metabolic control. Additionally, it seems to be a risk factor for hypoglycemia and was an independent predictor for asymptomatic hypoglycemia.

RESUMO

Aim: To evaluate retinal vascular perfusion and density by optical coherence tomography angiography (OCTA) before, during, and after hypoglycemia in individuals with diabetes mellitus with or without diabetic retinopathy (DR). Methods: A focused clinical history was performed, followed by an ophthalmological examination to document retinopathy status. OCTA was performed at baseline, at hypoglycemia, and at glucose normalization. Eye tracking and eye alignment devices on the platform were used to obtain a macular thickness cube (512 × 128) and vascular perfusion and density protocols of 3 × 3 mm. Retinal vascular reactivity was analyzed with superficial plexus vascular perfusion and density protocols on OCTA. Results: Fifty-two participants encompassing 97 eyes fulfilled the eligibility criteria. Their mean age was 42.9 ± 15.1 years (range, 22 to 65), and 20 (38.2%) were men. We found a statistically significant difference in vascular perfusion and density when comparing all groups at baseline. The controls had higher vascular perfusion and density values than the cases. Vascular perfusion and density were significantly reduced in all groups during the hypoglycemia episode, except for vascular density in DR cases. Conclusion: Acute hypoglycemia significantly alters the retinal vascularity in DM patients with and without DR, suggesting that repeated episodes of acute hypoglycemia could exacerbate retinopathy in the long term.

RESUMO

AIMS: This subanalysis of the SoliMix trial assessed the efficacy and safety of advancing basal insulin (BI) therapy with iGlarLixi versus BIAsp 30 in people with type 2 diabetes (T2D) living in Latin American (LATAM) countries, i.e. Argentina and Mexico (N = 160). MATERIALS AND METHODS: SoliMix (EudraCT: 2017-003370-13) was a 26-week, open-label, multicentre study, where adults with T2D suboptimally controlled with BI plus one or two oral glucose-lowering drugs and glycated haemoglobin (HbA1c) ≥7.5% to ≤10% were randomized to once-daily iGlarLixi or twice-daily BIAsp 30. Primary efficacy endpoints were non-inferiority in HbA1c reduction (margin 0.3%) or superiority in body weight change for iGlarLixi versus BIAsp 30. RESULTS: Both primary efficacy endpoints were met in the LATAM region. After 26 weeks, HbA1c was reduced by 1.8% with iGlarLixi and 1.4% with BIAsp 30, meeting non-inferiority [least squares mean difference -0.47% (95% confidence interval: -0.82, -0.11); p < .001]. iGlarLixi was superior to BIAsp 30 for body weight change [least squares mean difference -1.27% (95% confidence interval: -2.41, -0.14); p = .028]. iGlarLixi was also superior to BIAsp 30 for HbA1c reduction (p = .010). A greater proportion of participants achieved HbA1c <7% without weight gain and HbA1c <7% without weight gain and without hypoglycaemia with iGlarLixi versus BIAsp 30. Incidence and rates of American Diabetes Association Level 1 and 2 hypoglycaemia were lower with iGlarLixi versus BIAsp 30. CONCLUSIONS: Once-daily iGlarLixi provided better glycaemic control with weight benefit and less hypoglycaemia than twice-daily premix BIAsp 30. iGlarLixi may be a favourable alternative to premix BIAsp 30 in people with suboptimally controlled T2D to advance BI therapy in the LATAM region.

RESUMO

BACKGROUND AND AIMS: Evidence supports the efficacy and safety of the Hybrid Close loop (HCL) system in patients with type 1 diabetes (T1D). However, limited data are available on the long-term outcomes of patients on HCL with telemedicine follow-up. METHODS: A prospective observational cohort study including T1D patients, who were upgrading to HCL system. Virtual training and follow-up were done through telemedicine. CGM data were analyzed to compare the baseline time in range (TIR), time below range (TBR), glycemic variability and auto mode (AM), with measurements performed at 3, 6 and 12 months. RESULTS: 134 patients were included with baseline A1c 7.6% ± 1.1. 40.5% had a severe hypoglycemia event in the last year. Baseline TIR, measured two weeks after starting AM was 78.6 ± 9.94%. No changes were evident at three (Mean difference - 0.15;CI-2.47,2.17;p = 0.96), six (MD-1.09;CI-3.42,1.24;p = 0.12) and 12 months (MD-1.30;CI-3.64,1.04;p = 0.08). No significant changes were found in TBR or glycemic variability throughout the follow-up. Use of AM was 85.6 ± 17.5% and percentage of use of sensor was 88.75 ± 9.5% at 12 months. No severe hypoglycemic (SH) events were reported. CONCLUSIONS: HCL systems allow to improve TIR, TBR and glycemic variability safely, early and sustained up to 1 year of follow-up in patients with T1D and high risk of hypoglycemia followed through telemedicine.

RESUMO

INTRODUCTION: Maintaining glycemic control during and after physical activity (PA) is a major challenge in type 1 diabetes (T1D). This study compared the glycemic variability and exercise-related diabetic management strategies of adults with T1D achieving higher and lower PA loads in nighttime-daytime and active- sedentary behavior hours in free-living conditions. RESEARCH DESIGN AND METHODS: Active adults (n=28) with T1D (ages: 35±10 years; diabetes duration: 21±11 years; body mass index: 24.8±3.4 kg/m2; glycated hemoglobin A1c: 6.9±0.6%) on continuous subcutaneous insulin delivery system with predictive low glucose suspend system and glucose monitoring, performed different types, duration and intensity of PA under free-living conditions, tracked by accelerometer over 14 days. Participants were equally divided into lower load (LL) and higher load (HL) by median of daily counts per minute (61122). Glycemic variability was studied monitoring predefined time in glycemic ranges (time in range (TIR), time above range (TAR) and time below range (TBR)), coefficient of variation (CV) and mean amplitude of glycemic excursions (MAGE). Parameters were studied in defined hours timeframes (nighttime-daytime and active-sedentary behavior). Self-reported diabetes management strategies were analysed during and post-PA. RESULTS: Higher glycemic variability (CV) was observed in sedentary hours compared with active hours in the LL group (p≤0.05). HL group showed an increment in glycemic variability (MAGE) during nighttime versus daytime (p≤0.05). There were no differences in TIR and TAR across all timeframes between HL and LL groups. The HL group had significantly more TBR during night hours than the LL group (p≤0.05). Both groups showed TBR above recommended values. All participants used fewer post-PA management strategies than during PA (p≤0.05). CONCLUSION: Active people with T1D are able to maintain glycemic variability, TIR and TAR within recommended values regardless of PA loads. However, the high prevalence of TBR and the less use of post-PA management strategies highlights the potential need to increase awareness on actions to avoid glycemic excursions and hypoglycemia after exercise completion.

RESUMO

INTRODUCTION: There are data capture devices that attach to the FreeStyle Libre sensor and convert its communication from NFC (Near-field communication) to Bluetooth technology, generating real-time continuous glucose monitoring. The accuracy of hypoglycemia measurements displayed by smartphone apps using this device has not been established. METHODS: Study of diagnostic tests. Numerical accuracy was evaluated, utilizing the absolute difference with respect to capillary glucometry (ISO 15197:2015 standard) and clinical accuracy, using the Clarke and Parkes (Consensus) error grids, for glucose measurements less than 70mg/dL performed with the FreeStyle Libre system and with the digital estimation xDrip+ app, in diabetic patients managed with insulin therapy. RESULTS: Twenty-seven patients were included (TIR 73.4%, TBR70 5.6%), who contributed 83 hypoglycemic events. Numerical accuracy was adequate in similar proportions with the FreeStyle Libre system compared to the xDrip+ app (81.92% vs. 68.67%, p=0.0630). The clinical accuracy evaluation showed that 92.8% of the measurements for xDrip+ and 98.8% for FreeStyle libre met the criteria according to the Parkes (Consensus) grid (p=0.0535); and 79.5% and 91.6% of the measurements met the criteria according to the Clarke grid (p=0.0273), being higher with FreeStyle libre. CONCLUSIONS: The use of the NFC-Bluetooth transmitter (Miao-Miao) associated with the xDrip+ app does not improve numerical or clinical accuracy for detecting hypoglycemic events in diabetic patients managed with insulin therapy, compared to the FreeStyle Libre device.

RESUMO

Numerosas guías clínicas apoyan el uso de corticoides antenatales en embarazos menores de 34 semanas con riesgo de parto prematuro, ya que se asocian a menor morbimortalidad en este grupo al acelerar la maduración pulmonar y disminuir la incidencia de síndrome de distrés respiratorio. Sin embargo, existe menor evidencia del riesgo versus beneficio de esta medida en partos prematuros tardíos. El objetivo de este trabajo es realizar una revisión de la literatura actual con respecto al uso de corticoides antenatales en embarazos con riesgo de parto prematuro entre las 34 y 36+6 semanas. Métodos: Se realizó una revisión de la literatura relevante en PubMed, tanto en inglés como en español, desde 1997. Resultados: Se presentan estudios que demuestran beneficios a corto plazo relacionados con una disminución de la morbilidad respiratoria en los recién nacidos prematuros tardíos que recibieron corticoides antenatales. Pese a esto, es preocupante la mayor incidencia de hipoglicemia neonatal. Por otro lado, se presentan estudios que describen efectos neurocognitivos negativos a largo plazo en el mismo grupo poblacional. Finalmente, se describen las recomendaciones actuales de diversas guías clínicas en cuanto al uso de corticoides antenatales en este grupo. Conclusión: Actualmente, el uso de corticoides antenatales en prematuros tardíos no es una recomendación estándar para toda la población. Existen estudios recientes que muestran, beneficios a corto plazo de su uso en este grupo de pacientes, sin embargo, persisten dudas sobre el riesgo hipoglicemia neonatal y posibles efectos adversos a largo plazo en la esfera neuropsiquiátrica.

Introduction: Numerous clinical guidelines support the use of antenatal corticosteroids in pregnancies under 34 weeks at risk of premature delivery, since they are associated with lower morbidity and mortality in this group by accelerating lung maturation and reducing the incidence of respiratory distress syndrome. However, there is less evidence of the benefit of antenatal corticosteroids in late preterm deliveries. The objective of this work is to review the current literature regarding the use of antenatal corticosteroids in pregnancies at risk of preterm birth between 34 and 36+6 weeks. Methods: A review of the relevant literature was conducted in PubMed, both in English and Spanish, since 1997. Results: We present studies that demonstrate short-term benefits related to respiratory morbidity in late preterm infants who received antenatal corticosteroids. Nevertheless, some studies show an increased incidence of neonatal hypoglycemia. On the other hand, some studies show long-term negative neurocognitive effects in the same population group. Finally, the current recommendations of various clinical guidelines regarding the use of antenatal corticosteroids in this group are described. Conclusions: Currently, the use of antenatal corticosteroids in late preterm infants is not a standard recommendation for the entire population. There are recent studies that show short-term benefits of its use in this group of patients, however, doubts remain about the risk of neonatal hypoglycemia and possible long-term adverse effects in the neuropsychiatric sphere.

RESUMO

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.

RESUMO

Insulin antibodies (IAs) induced by exogenous insulin rarely cause hypoglycemia. However, insulin autoantibodies (IAAs) in insulin autoimmune syndrome (IAS) can cause hypoglycemia. The typical manifestations of IAS are fasting or postprandial hypoglycemia, elevated insulin level, decreased C-peptide levels, and positive IAA. We report a 45-year-old male with type 1 diabetes mellitus (T1DM) treated with insulin analogues suffering from recurrent hypoglycemic coma and diabetic ketoacidosis (DKA). His symptoms were caused by exogenous insulin and were similar to IAS. A possible reason was that exogenous insulin induced IA. IA titers were 61.95% (normal: < 5%), and the concentrations of insulin and C-peptide were > 300 mU/L and < 0.02 nmol/L when hypoglycemia occurred. Based on his clinical symptoms and other examinations, he was diagnosed with hyperinsulinemic hypoglycemia caused by IA. His symptoms improved after changing insulin regimens from insulin lispro plus insulin detemir to recombinant human insulin (Gensulin R) and starting prednisone.

RESUMO

AIMS: Two fixed-ratio combinations (FRCs) of basal insulin and glucagon-like peptide-1 receptor agonist (GLP-1RA) are available for once-daily use in adults with type 2 diabetes. We aimed to review the clinical evidence for the efficacy and safety of changing treatment from a basal-bolus insulin (BBI) regimen or a premix insulin to these combination treatments (fixed-ratio or loose) and provide expert opinion on the practicalities of making such a change. METHODS: Relevant clinical and trial evidence and general review articles were identified through a literature review of ProQuest (comprising BIOSIS Previews®, Current Contents® Search, Embase® and MEDLINE®) for articles published between 2009 and 2021. RESULTS: We identified nine articles reporting the results of FRCs, and seven articles reporting results of loose combinations of basal insulin and GLP-1RAs, in people who transitioned treatment from BBI or premix regimens. In most trials, combination treatment led to improved or equivalent glycaemic control, and a reduction in body weight or BMI, versus the original regimens. Some trials reported a reduction in total insulin dose. A few trials reported reduced or unchanged hypoglycaemia rates, or increased patient satisfaction, with combination therapy where these endpoints were examined. We provide guidance on transitioning of treatment and the patient types most likely to benefit. CONCLUSIONS: In people not achieving glycaemic control with BBI or premix insulin regimens, an FRC or loose combination of basal insulin and GLP-1RA may improve control, decrease the risk of body weight gain or hypoglycaemia and reduce the complexity of treatment.

RESUMO

Background: Type 2 diabetes mellitus (T2DM) is a chronic, highly prevalent disease with a significant impact on health. Appropriate treatment requires effective and timely escalation to achieve metabolic control. To evaluate the effectiveness and safety of IDegLira on adults with T2DM previously treated with oral antidiabetics and/or insulin in a real-life setting. Methods: An observational study in a real-world setting was conducted. Patients were selected from the outpatient clinic of two centers dedicated to specialized diabetes care. Main outcomes were HbA1c, body weight, insulin dose changes, hypoglycemia, and other adverse events. Results: 67 T2DM patients treated with IDegLira were monitored between 3 and 7 months. At the end of foll ow-up, the median change in HbA1c was -1.05% (CI95% -1.45, -0.65), and a decrease in insulin requirement was also observed (mean difference -10 TDD units (CI95% - 17 to -2.5). No treatment discontinuation was reported, hypoglycemia events were reported in 3 patients at the end of follow-up versus 8 patients at baseline. Conclusions: This real-life study shows the effectiveness in glycemic control of IDegLira use in T2DM patients who do not achieve goals with other therapies, with an adequate safety profile. The findings need to be confirmed with evaluation of therapeutic results in larger cohorts.

Los anticuerpos contra la insulina (AI) inducidos por la insulina exógena raramente causan hipoglucemia. No obstante, los autoanticuerpos contra la insulina (AIA) en el síndrome autoinmune de insulina (SAI) pueden causar hipoglucemia. Las manifestaciones típicas del SAI son la hipoglucemia en ayunas o posprandial, niveles elevados de insulina, la disminución del nivel de péptido C y AIA positivos. Presentamos un paciente hombre de 45 años con diabetes mellitus de tipo 1 (DMT1) tratado con análogos de insulina, que sufría comas hipoglucémicos recurrentes y cetoacidosis diabética (CAD). Sus síntomas fueron causados por la insulina exógena y fueron similares al SAI. La posible razón fue que la insulina exógena indujo AI. El título de AI era del 61,95% (Normal: 300 mU/L y < 0,02 nmol/L cuando se producía la hipoglucemia. Basados en sus síntomas clínicos y otros exámenes, se le diagnosticó hipoglucemia hiperinsulinémica causada por la AI. Sus síntomas mejoraron después de cambiar el régimen de insulina de lispro más insulina detemir a insulina humana recombinante (Gensulin R) y de empezar a tomar prednisona.

RESUMO

BACKGROUND: My Dose Coach (MDC) is a mobile application combined with a web portal that can suggest optimized basal insulin (BI) injection doses using Self-Measured Plasma Glucose (SMPG) and hypoglycemia data. This study aimed to evaluate its efficacy on patients reaching SMPG and Fasting blood glucose (FBG) target range 90-130 mg/dl (5-7.2 mmol/L) goals without severe hypoglycemic episodes. We also addressed the mean reduction in glycated hemoglobin (A1C), FBG, and SMPG and the improvement in the WHO's Five Well Being Index (WBI). METHODS: This prospective pilot study involved the use of MDC in outpatients with type 2 diabetes (T2DM) from a Hospital in Northern Mexico. Patients on treatment with any BI were included in the study. The follow-up was of 16 weeks. Student t-tests or McNemar test were used for effect comparisons. RESULTS: We included 158 patients (46.8% women), mean (SD) age 51 (10.3) years. We achieved SMPG target range in 58.9% [mean (95CI) reduction of 30.9 mg/dl (22.5-37.7; P < .001)] of the patients [66(28) days], with no severe hypoglycemia events. FBG goal was reached in 55.7% [mean (95CI) reduction of 63.4 mg/dl (49.6-77.2; P < .001)]. The mean (95CI) reduction of A1C was 1.78% (1.47-2, P < .01) with the last observation carried forward. There was a mean (95CI) increase of 2.23 (-3, -1.4, P < .01) points in WBI scale. CONCLUSIONS: MDC successfully helped to achieve FBG and SMPG goals, reduced A1C, and increased WBI with no severe hypoglycemia events.

RESUMO

The insulin microinfuser with integrated system (SAPT) for patients with type 1 Diabetes Mellitus (T1D) is included in the national financial protection system for high-cost treatments. OBJECTIVE: To describe the initial and first-year metabolic outcomes and epidemiological and nutritional characteristics of T1D pediatric patients treated with SAPT. PATIENTS AND METHOD: Retrospective, descriptive and analytical study of clinical records from 2017 to 2019, of 12 patients with T1D users of SAPT, attended in a referral hospital. VARIABLES: age at program entry, time of evolution of the disease, type of insulin treatment and type of glucose monitoring (capillary: sample or Continuous Glucose Monitoring [CGM]) at program entry, cause of application to the program, nutritional status, rural or urban origin, educational level of the main guardian, HbA1c at application and in the last month of each quarter after SAPT installation, over a 12-month period. HbA1c analysis was venous sample by High-Performance Liquid Chromatography and follow-up was capillary sample by Latex Particle Agglutination Inhibition. RESULTS: The median variables at 12 months of treatment were Total Daily Dose (TDD) 0.74, %Basal (%B) 49%, Time In Range (TIR) 39%, Time Below Range (TBR) 1%, and HbA1c 7.7%. The sensor usage time was met in all cases and only half of them achieved a correct execution of hyperglycemia and hypoglycemia treatment. Inadvertent severe hypoglycemia was the main cause of application to the program. CONCLUSION: TDD and %B increased, approaching physiological requirement, although without statistical significance, which could be attributed to the administra tion of adequate insulin with lower risk of hypoglycemia due to predictive suspension and CGM. TIR presented a favorable increase, although not significant, nor reaching the target range, attributable to the short observation time, difficulties in understanding and execution of our patients, and the learning process of the treating clinical team. SAPT was effective in hypoglycemia management and effective in improving HbA1c.

RESUMO

This study investigated whether a 30-day co-treatment with 1 g/kg glutamine dipeptide (GdiP) and 1 U/kg regular (rapid acting) or 5 U/kg degludec (long acting) insulins modifies glucose homeostasis and liver metabolism of alloxan-induced type 1 diabetic (T1D) male Swiss mice undergoing insulin-induced hypoglycemia (IIH). Glycemic curves were measured in fasted mice after IIH with 1 U/kg regular insulin. One hour after IIH, the lipid profile and AST and ALT activities were assayed in the serum. Morphometric analysis was assessed in the liver sections stained with hematoxylin-eosin and glycolysis, glycogenolysis, gluconeogenesis and ureagenesis were evaluated in perfused livers. T1D mice receiving GdiP or the insulins had a smaller blood glucose drop at 60 minutes after IIH, which was not sustained during the subsequent period up to 300 minutes. The 30-day treatment of T1D mice with insulin degludec, but not with regular insulin, improved fasting glycemia, body weight gain and serum activity of AST and ALT. Treatments with insulin degludec, GdiP and insulin degludec + GdiP decreased the liver capacity in synthesizing glucose from alanine. GdiP, in combination with both insulins, was associated with increases in the serum triglycerides and, in addition, regular insulin and GdiP increased AST and ALT activities, which could be the consequence of hepatic glycogen overload. GdiP and the insulins improved the IIH, although to a small extent. Caution is recommended, however, with respect to the use of GdiP because of its increasing effects on serum triglycerides and AST plus ALT activities.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the frequency of hypoglycemia and the treatment satisfaction in patients with type 1 diabetes (T1D) using insulin analogues. METHODS: This observational retrospective study included 516 adult patients with T1D from 38 cities in Southern Brazil. Demographics and clinical data were collected using a self-report questionnaire. Hypoglycemia was defined as an event based on either symptoms or self-monitored blood glucose < 70 mg/dL. Treatment satisfaction was evaluated using the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and with a specific question with scores ranging from 0-10. Common mental disorders were assessed using the General Health Questionnaire (GHQ-12). RESULTS: Overall, the mean age was 38 ± 14 years and 52% of the participants were women. The median diabetes duration was 18 years. The scores for insulin analogue treatment satisfaction were higher than those for previous treatments. DTSQ scores had a median value of 32 (interquartile range 29-35) and remained unchanged over time. The percentage of patients with hypoglycemia (including severe and nocturnal) was comparable across groups divided according to duration of use of insulin analogues. Most patients (n=395, 77%) screened positive for common mental disorders. CONCLUSION: Patient satisfaction with insulin analogue treatment was high and remained unchanged with time. Episodes of hypoglycemia also remained unchanged over time among patients using insulin analogues.
