RESUMO
Aims: To compare glycemic control and maternal-fetal outcomes of women with type 1 diabetes (T1D) using hybrid closed loop (HCL) versus multiple daily insulin injections (MDI) plus continuous glucose monitoring. Methods: Multicenter prospective cohort study of pregnant women with T1D in Spain. We evaluated HbA1c and time spent within (TIR), below (TBR), and above (TAR) the pregnancy-specific glucose range of 3.5-7.8 mmol/L. Adjusted models were performed for adverse pregnancy outcomes, including baseline maternal characteristics and center. Results: One hundred twelve women were included (HCL n = 59). Women in the HCL group had a longer duration of diabetes and higher rates of prepregnancy care. There was no between-group difference in HbA1c in any trimester. However, in the second trimester, MDI users had a greater decrease in HbA1c (-6.12 ± 9.06 vs. -2.16 ± 7.42 mmol/mol, P = 0.031). No difference in TIR (3.5-7.8 mmol/L) and TAR was observed between HCL and MDI users, but with a higher total insulin dose in the second trimester [+0.13 IU/kg·day)]. HCL therapy was associated with increased maternal weight gain during pregnancy (ßadjusted = 3.20 kg, 95% confidence interval [CI] 0.90-5.50). Regarding neonatal outcomes, newborns of HCL users were more likely to have higher birthweight (ßadjusted = 279.0 g, 95% CI 39.5-518.5) and macrosomia (ORadjusted = 3.18, 95% CI 1.05-9.67) compared to MDI users. These associations disappeared when maternal weight gain or third trimester HbA1c was included in the models. Conclusions: In a real-world setting, HCL users gained more weight during pregnancy and had larger newborns than MDI users, while achieving similar glycemic control in terms of HbA1c and TIR.

INTRODUCTION: Despite better treatments and care for patients with type 1 diabetes (T1DM), all-cause and cardiovascular mortality still remains higher compared to the general population. We evaluated mortality and risk factors for mortality in a representative cohort of patients with T1DM. METHODS: DIACAM1 was a cross-sectional, multicenter study on adult patients (≥ 16 years old) and diabetes with at least 5 years since diabetes diagnosis conducted between 2009 and 2010. DIACAM1 2010-2020 study was a follow-up study, extension of DIACAM1, where vital status of patients was evaluated between June 2019 and June 2020. RESULTS: 4.03% [CI95%, 2.53-5.62) of the 1465 patients with T1DM included in the cohort of the DIACAM1 in 2010 had died. Survival was lower than in the sex- and age-matched general population in the same region. 40.7% of deaths were due to cardiovascular disease. HbA1c levels < 7% and triglyceride levels < 150 mg/dL were associated with lower mortality, whereas retinopathy and plasma creatinine were associated with increased mortality. CONCLUSIONS: We confirmed a lower survival in people with T1DM, with cardiovascular disease being the main cause of mortality. High HbA1c, high triglycerides, retinopathy, and high creatinine are factors associated with mortality.

This study aimed to evaluate the effectiveness and safety of the MiniMed™ 780G advanced hybrid closed-loop (AHCL) system in people with type 1 diabetes (T1D) previously treated with continuous subcutaneous insulin infusion combined with flash glucose monitoring in a real-life setting. A total of 47 subjects (mean age 41 ± 13.6 years, 60% females, diabetes duration 28 ± 11 years) were included and switched to an AHCL system. Baseline and 6-month data were analyzed. Time in range 70-180 mg/dL increased from 65.3% at baseline to 73.8% at 6 months. Time in hyperglycemia >180 mg/dL decreased from 26.6% to 19.3%. Time in hypoglycemia <70 mg/dL decreased from 4.6% to 2.3%. The coefficient of variation also decreased from 36% to 31.6%. No episodes of severe hypoglycemia, diabetes ketoacidosis, or diabetes-related hospital admissions occurred. In conclusion, the MiniMed 780G AHCL system enables the safe achievement of recommended glycemic targets in people with T1D after 6 months of use.

OBJECTIVE: To evaluate the prevalence of autoimmune diseases (AD) associated with type 1 diabetes mellitus (T1DM). PATIENTS AND METHODS: Analytical cross-sectional study, nested in a multicenter prospective cohort of 1121 adults with DM1 with active follow-up in endocrinology clinics. Sociodemographic and clinical variables and the presence of AD were analysed in 2010 and 2020. RESULTS: In this second analysis, 49,5% were male, mean age was 49.4 ± 12.8 years, median T1DM duration was 27,1 years (20,7-35,1) and mean glycated hemoglobin was 7.66 ± 1.06%. There is an absolute increase of 13% (95% CI 11-15) (p < 0.001) of patients with at least one AE and an absolute increase of 11.6% (95% CI 9.7-13.5) (p < 0.0001) of any type of autoimmune thyroid disease (ATD) after 10 years of follow-up. Likewise, the prevalence of celiac disease, autoimmune gastritis and other AD increased statistically significantly. In the multivariate logistic regression analysis, the factors that were independently associated with the presence of ATD were female gender [OR 2.9 (95% CI 2.3-3.7); p < 0.0001] and the presence of type 1 b diabetes (OR 0.5 [95% CI 0.3-0.9]; p = 0.041). CONCLUSIONS: After 10 years of follow-up, there is a substantial increase in other types of AE in patients with DM1. It seems necessary to carry out a systematic screening of these AD to optimize the follow-up of patients with 1 TDM, mainly of the ATD.

Objectives: The aim of this study is to investigate in depth diabetes mellitus associated with immune checkpoint inhibitors (DM-ICIs) by analysing a case series. We also evaluated the clinical impact of flash glucose monitoring (FGM) systems in the management of this entity. Methods: We conducted an observational cohort study of DM-ICIs diagnosed in two hospitals in Seville (Spain). Patients with a new diagnosis of diabetes mellitus (DM) or with sudden worsening of preexisting DM after starting treatment with ICIs, with a random 5 hour-postprandial C-peptide value of <0.6 nmol/L and without possibility of subsequent withdrawal of insulin treatment, were included. Results: A total of 7 cases were identified, mostly males (n = 6; 85.7%), with a mean age of 64.9 years. The mean glycated hemoglobin (HbA1c) upon diagnosis was 8.1%, with diabetic ketoacidosis (DKA) observed in 6 cases (85.7%). Subcutaneous flash glucose monitoring (FGM) systems were used in six cases, with a mean follow-up period of 42.7 weeks. During the first 90 days of use, mean average glucose was 167.5 mg/dL, with a coefficient of variation (CV) of 34.6%. The mean time in the range 70-180 mg/dL (TIR) was 59.7%, with a mean time above range (TAR) 181-250 mg/dL of 27.8% and a mean TAR > 250 mg/dL of 10.2%. The mean time below range (TBR) 54-69 mg/dL was 2%, while the mean TBR < 54 mg/dL was 0.3%. The mean glucose management indicator (GMI) was 7.3%. No significant differences were observed in FGM values for the following 90 days of follow-up. A progressive improvement in all parameters of glycaemic control was observed between the first month of FGM use and the sixth month of FGM use. Of note, there was a decrease in mean CV (40.6% to 34.1%, p = 0.25), mean TAR 181-250 (30.3% to 26%, p = 0.49), mean TAR > 250 mg/dL (16.3% to 7.7%, p = 0.09), mean TBR 54-69 mg/dL (5.2% to 2%, p = 0.16), and mean TBR < 54 mg/dL (1.8% to 0.2%, p = 0.31), along with an increase in mean values of TIR 70-180 mg/dL (46.5% to 60.5%, p = 0.09). The lack of statistical significance in the differences observed in the mean FGM values over the follow-up period may be related to the small sample size. Conclusion: DM-ICI is recognised by a state of sudden-onset insulinopenia, often associated with DKA. The use of FGM systems may be a valid option for the effective management of DM-ICIs and for the prevention of severe hyperglycaemic and hypoglycaemic episodes in this condition.

BACKGROUND: Despite major medical advances, Type 1 Diabetes (T1D) patients still have greater morbimortality than the general population. Our aim was to describe our cohort of T1D patients and identify potential risk factors susceptible to prevention strategies. METHODS: Cross-sectional, observational study, including T1D patients treated at our center, from 1 March 2017 to 31 March 2020. INCLUSION CRITERIA: T1D, age > 14 years and signed informed consent. EXCLUSION CRITERIA: diabetes other than T1D, age < 14 years and/or refusal to participate. RESULTS: Study population n = 2181 (49.8% females, median age at enrollment 41 years, median HbA1c 7.7%; 38.24% had at least one comorbidity). Roughly 7.45% had severe hypoglycemia (SH) within the prior year. Macro/microvascular complications were present in 42.09% (5.83% and 41.14%, respectively). The most frequent microvascular complication was diabetic retinopathy (38.02%), and coronary disease (3.21%) was the most frequent macrovascular complication. The risk of complications was higher in males than in females, mainly macrovascular. Patients with SH had a higher risk of complications (OR 1.42; 1.43 in males versus 1.42 in females). CONCLUSIONS: Our T1D population is similar to other T1D populations. We should minimize the risk of SH, and male patients should perhaps be treated more aggressively regarding cardiovascular risk factors.
RESUMO
OBJECTIVE: To evaluate degree of metabolic control and treatment regimens in patients with type 1 diabetes mellitus (T1DM) enrolled in the DIACAM1 study, after 10 years of follow-up under routine clinical practice conditions. PATIENTS AND METHODS: A total of 1,465 patients enrolled in the DIACAM1 study, a multicentre, cross-sectional study conducted in Castilla-La Mancha in 2010, were analysed. Of these patients, 58 (4%) died during the 10-year follow-up period. Anthropometric, clinical, laboratory and treatment data were reviewed for 1,121 (76.5%) patients in active follow-up. RESULTS: Mean glycosylated haemoglobin (HbA1c) levels were 7.66% lower than in 2010 (p<0.001), 26% of patients achieved HbA1c levels <7%, 24.4% were obese, 51.7% had dyslipidaemia and 33.6% had hypertension. The following were found to be predictive factors for good glycaemic control (HbA1c<7%): good glycaemic control in 2010 (odds ratio [OR] 4.8); the use of intensified insulin regimens, including the Institute for Clinical Systems Improvement (ICSI) guideline and glucose monitoring (OR 2.8); no hyperlipidaemia (OR 1.97); and higher levels of education (OR 1.4). The recommended targets for lipid and blood pressure control were met by 76% of patients; 40% of the patients enrolled required drug treatment. CONCLUSIONS: Glycaemic control in patients with T1DM in Castilla-La Mancha improved after 10 years of follow-up. The use of intensified insulin regimens and technology applied to diabetes care appear to be determining factors in achieving this improvement. Despite the increase in the prevalence of cardiovascular risk factors, the majority of the patients achieved good lipid and blood pressure control.

AIM: To evaluate clinical status and mortality in older adults with long-standing type 1 diabetes mellitus (T1D). METHODS: Cross-sectional analysis of all patients with T1D for 50 years or more from a cohort followed since 2010 at Castilla-La Mancha Public Health Service (Spain). Primary outcome was HbA1c change during the follow-up (2010-2020 period). Secondary outcomes included evaluation of insulin and continuous glucose monitoring (CGM) use, cardiovascular risk factors (CVRF), diabetes chronic complications and mortality. RESULTS: A total of fifty-five T1D patients were analysed. Mean age was 69.5 ± 8.3 yrs. and T1D duration of 54.7 ± 4.7 yrs. We detected a HbA1c reduction of -0.5% (-6 mmol/mol) [95% CI -0.1, -0.9 (-2, -10); P = 0.016]. CGM was used by 26% of the patients. More patients suffered from hypertension and obesity in 2020 (66% vs. 78%, P = 0.016; and 26% vs. 31%, P = 0.016; respectively). An increase of diabetic polyneuropathy was detected (45% vs. 67%, P = 0.008). Rate of mortality was higher among patients with long-standing T1D (26% vs. 3.5%, P < 0.001), due to cardiovascular disease (57%). CONCLUSIONS: Older adults with long-standing T1D patients improved glycemic control although a worsening of CVRF and higher mortality rateweredetected.

Thyrotoxicosis factitia is defined as thyrotoxicosis resulting from exogenous ingestion of thyroid hormone, usually in patients with a psychiatric disorder. Diagnosis can be difficult and this entity should be suspected in patients with high free tiroxine (T4) concentrations, low or suppressed thyroglobulin concentrations, normal urinary iodide excretion and low or suppressed (131)I uptake. To establish the differential diagnosis, thyrotoxicosis factitia must be distinguished from several diseases with low (131)I uptake, such as Graves' disease, subacute thyroiditis, hyperthyroidism due to excessive iodine intake, struma ovarii and metastasis from thyroid cancer. Treatment is based on b-blockers to reduce symptoms and avoid iatrogeny. We present a case of thyrotoxicosis factitia treated in our outpatient clinic.
RESUMO
Previous studies of bone turnover markers in diabetes are limited, and the results are conflicting. Our aim was to evaluate differences in bone turnover markers and i-PTH between T2DM and non-diabetes subjects. Cross-sectional study including 133 subjects (78 T2DM, 55 without diabetes). BMD were measured by dual X-ray absorptiometry. Bone turnover markers were determined in serum. Serum levels of bone resorption markers (CTX and TRAP5b) were lower in T2DM compared with non-diabetes subjects. There were no differences in bone formation markers. i-PTH serum levels were lower in T2DM: 38.35 ± 18.20 pg/ml versus 50.22 ± 18.99 pg/ml, P < 0.05. TRAP5b and CTX were positively correlated with i-PTH (CTX: r = 0.443, P < 0.001; TRAP5b: r = 0.180, P = 0.047). There was an inverse relationship between TRAP5b levels and diabetes duration (r = -0.269, P = 0.021). T2DM patients have lower levels of bone resorption markers, and i-PTH compared with subjects without diabetes. Lower levels of PTH may induce a low turnover state as reflected by lower levels of bone resorption markers, and this situation may influence the higher risk of fracture of T2DM.

Wegener's granulomatosis (WG) is a systemic disease with a complex genetic background. It is characterised by inflammation of the small blood vessels leading to damage in any number of organs. The common features include granulomatous inflammation of the respiratory tract and kidneys. Most patients have measurable autoantibodies against neutrophil proteinase-3 (Antineutrophil Cytoplasmic Antibody, ANCA). Pituitary involvement is a rare complication of this disease and, when it occurs, diabetes insipidus is the most common manifestation. We describe a 38-year-old female with known long-term WG who presented with partial hypopituitarism, severe malnutrition and ANCA negative status, with a favourable response to steroid pulse therapy.
