Myxedema Coma as a Presentation of Panhypopituitarism Secondary to Traumatic Brain Injury.

Background/Objective: Myxedema coma typically presents with decreased level of consciousness and hypothermia, often due to thyroid pathology. In central causes, normal thyroid-stimulating hormone (TSH) levels may delay diagnosis. The purpose of this report is to describe a patient with a history of head trauma who presented with myxedema coma as a manifestation of panhypopituitarism. Case Report: The admitted patient was a 52-year-old man who presented with mental and physical slowness, drowsiness, and weakness. He also had hypotension, hypoglycemia, and low oxygen saturation. Initial evaluation revealed severe pericardial and bilateral pleural effusions, plasma TSH of 2.42 mU/L (normal range 0.25-5.00 mU/L), and plasma adrenocorticotropic hormone (ACTH) of 7.1 pg/mL (normal range 5.2-40.3 pg/mL). Later, his condition deteriorated with anasarca and coma. Signs of improvement were noted after intravenous corticosteroid administration. A subsequent blood test was conducted, which showed a free thyroxine (FT4) level of 0.14 ng/dL (normal range 0.93-1.70 ng/dL). A cranial magnetic resonance scan revealed posttraumatic lesions. The patient's family later admitted head injuries at home. Treatment with intravenous levothyroxine was initiated, resulting in improvement and subsequent discharge in perfect alertness. Conclusion: Hypopituitarism should be suspected in patients with head trauma and symptoms of hormone deficiency. Advanced clinical forms, such as myxedema coma, may also occur. Pituitary hormone levels might be in the normal range, so target gland hormones should be assessed to reach a diagnosis. In the case of suspected central hypothyroidism, requesting only TSH levels may result in a missed diagnosis. For this reason, both TSH and FT4 levels should be measured when central hypothyroidism is suspected.

Pituitary Apoplexy: Comorbidities, Management and Outcomes. A Spanish Observational Multicenter Study.

BACKGROUND: Pituitary apoplexy (PA) is the paradigm of endocrine and neurosurgical emergency. OBJECTIVE: To evaluate the comorbidities, risk factors, clinical presentation, pituitary apoplexy score (PAS) and the outcomes of surgical vs. conservative management of PA in Spain. METHODS: Spanish multicenter, observational study of 301 patients with acute PA. Statistical analyses compared risk factors, clinical presentation and outcomes between the surgical and conservative treatment groups, adjusting for potential confounders. The prevalence of cardiovascular risk factors in patients with pituitary apoplexy was compared with the Spanish population and with patients with non-functioning pituitary adenomas. RESULTS: Median age was 59.3 years, 201 (66.8%) were men and non-functioning adenomas (77.9%) were the most common tumor type. The prevalence of diabetes (20.3% vs 13.9%, p<0.01), hypertension (48.8% vs 33.4%, p<0.01) and dyslipidemia (44.2% vs 23.3%, p<0.01), exceeded the Spanish age-adjusted population prevalence. Overall, 209 (69.4%) underwent surgery and 92 (30.6%) received conservative treatment. Surgical patients had larger tumors (26.2 vs 21.0 mm, p<0.01), chiasmal compression more frequently (77.2% vs 53.4%, p<0.01) and higher values of PAS. In the follow-up, while there were no statistically significant differences in anterior pituitary hormonal deficits between treatments, permanent vasopressin deficiency was more frequent after surgery (14.8% vs 3.3%, p<0.01). CONCLUSION: There is a high burden of cardiovascular risk factors among patients with PA suggesting that metabolic factors may play a potential role in the development of PA. This underscores the need for comprehensive management of these conditions in addition to treating the apoplexy itself in this population. Surgical management has a relevant place in PA approach mainly in patients with higher PAS. However, it leads permanent vasopressin deficit more frequently than conservative approach.

Natural history and surgical outcomes of Rathke's cleft cysts: a Spanish multicenter study.

Rathke's cleft cysts (RCC) are a common type of lesion found in the sellar or suprasellar area. They are usually monitored clinically, but in some cases, surgery may be required. However, their natural progression is not yet well understood, and the outcomes of surgery are uncertain. The objective of this study is to evaluate the natural history of Rathke's cleft cysts in patients who are clinically monitored without treatment, and to determine the outcomes of surgery and the incidence of recurrences over time. Design and patients: National multicentric study of patients diagnosed of Rathke's cleft cyst (RCC- Spain) from 2000 onwards and followed in 15 tertiary centers of Spain. A total of 177 patients diagnosed of RCC followed for 67.3 months (6-215) and 88 patients who underwent surgery, (81 patients underwent immediate surgery after diagnosis and 7 later for subsequent growth) followed for 68.8 months (3-235). Results: The cyst size remained stable or decreased in 73.5% (133) of the patients. Only 44 patients (24.3%) experienced a cyst increase and 9 of them (5.1%) experienced an increase greater than 3 mm. In most of the patients who underwent surgery headaches and visual alterations improved, recurrence was observed in 8 (9.1%) after a median time of 96 months, and no predictors of recurrence were discovered. Conclusions: Rathke's cleft cysts without initial compressive symptoms have a low probability of growth, so conservative management is recommended. Patients who undergo transsphenoidal surgery experience rapid clinical improvement, and recurrences are infrequent. However, they can occur after a long period of time, although no predictors of recurrence have been identified.

Glucose metabolism outcomes after pituitary surgery in patients with acromegaly.

AIM: To investigate the impact of pituitary surgery on glucose metabolism and to identify predictors of remission of diabetes after pituitary surgery in patients with acromegaly. METHODS: A national multicenter retrospective study of patients with acromegaly undergoing transsphenoidal surgery for the first time at 33 tertiary Spanish hospitals (ACRO-SPAIN study) was performed. Surgical remission of acromegaly was evaluated according to the 2000 and 2010 criteria. RESULTS: A total of 604 acromegaly patients were included in the study with a total median follow up of 91 months (interquartile range [IQR] 45-163). At the acromegaly diagnosis, 23.8% of the patients had diabetes mellitus (DM) with a median glycated hemoglobin (HbA1c) of 6.9% (IQR 6.4-7.9) [51.9 mmol/mol (IQR 46.4-62.8)]. In the multivariate analysis, older age (odds ratio [OR] 1.02, 95% CI 1.00-1.05), dyslipidemia (OR 5.25, 95% CI 2.81 to 9.79), arthropathy (OR 1.39, 95% CI 2.82 to 9.79), and higher IGF-I levels (OR 1.30, 95% CI 1.05 to 1.60) were associated with a greater prevalence of DM. At the last follow-up visit after surgery, 21.1% of the DM patients (56.7% of them with surgical remission of acromegaly) experienced diabetes remission. The cure rate of DM was more common in older patients (hazard ratio [HR] 1.77, 95% CI 1.31 to 2.43), when surgical cure was achieved (HR 2.10, 95% CI 1.01 to 4.37) and when anterior pituitary function was not affected after surgery (HR 3.38, 95% CI 1.17 to 9.75). CONCLUSION: Glucose metabolism improved in patients with acromegaly after surgery and 21% of the diabetic patients experienced diabetes remission; being more frequent in patients of older age, and those who experienced surgical cure and those with preserved anterior pituitary function after surgery.

Pegvisomant and pasireotide in PRL and GH co-secreting vs GH-secreting Pit-NETs.

The objective of the study was to evaluate the efficacy of second-line therapies in patients with acromegaly caused by a growth hormone (GH) and prolactin (PRL) co-secreting pituitary neuroendocrine tumor (GH&PRL-Pit-NET) compared to their efficacy in patients with acromegaly caused by a GH-secreting pituitary neuroendocrine tumor (GH-Pit-NET). This is a multicenter retrospective study of patients with acromegaly on treatment with pasireotide and/or pegvisomant. Patients were classified in two groups: GH&PRL-Pit-NETs when evidence of hyperprolactinemia and immunohistochemistry (IHC) for GH and PRL was positive or if PRL were >200 ng/dL regardless of the PRL-IHC and GH-Pit-NETs when the previously mentioned criteria were not met. A total of 28 cases with GH&PRL-Pit-NETs and 122 with GH-Pit-NETs met the inclusion criteria. GH&PRL-Pit-NETs presented at a younger age, caused hypopituitarism, and were invasive more frequently than GH-Pit-NETs. There were 124 patients treated with pegvisomant and 49 with pasireotide at any time. The efficacy of pegvisomant for IGF-1 normalization was of 81.5% and of pasireotide of 71.4%. No differences in IGF-1 control with pasireotide and with pegvisomant were observed between GH&PRL-Pit-NETs and GH-Pit-NETs. All GH&PRL-Pit-NET cases treated with pasireotide (n = 6) and 82.6% (n = 19/23) of the cases treated with pegvisomant normalized PRL levels. No differences in the rate of IGF-1 control between pegvisomant and pasireotide were detected in patients with GH&PRL-Pit-NETs (84.9% vs 66.7%, P = 0.178). We conclude that despite the more aggressive behavior of GH&PRL-Pit-NETs than GH-Pit-NETs, no differences in the rate of IGF-1 control with pegvisomant and pasireotide were observed between both groups, and both drugs have shown to be effective treatments to control IGF-1 and PRL hypersecretion in these tumors.

Hypoglycemia during hyperosmolar hyperglycemic crises is associated with long-term mortality.

BACKGROUND: Previous research has indicated that hypoglycemia during hospitalization is a predictor of unfavorable outcomes in patients with diabetes. However, no studies have examined the long-term impact of hypoglycemia in adults admitted for hyperglycemic crises. The study was aimed to investigate the long-term implications of hypoglycemia during hyperosmolar hyperglycemic crises, particularly in terms of all-cause mortality. METHODS: This retrospective cohort study included 170 patients (82 men [48.2%], median age 72 years) admitted to a university hospital for hyperosmolar hyperglycemic crises, including pure hyperosmolar hyperglycemic states and hyperosmolar diabetic ketoacidoses. We separately investigated the prognostic significance of hypoglycemia on mortality during the initial intravenous insulin therapy phase and during the later subcutaneous insulin therapy phase, both during hospitalization and in the long term (median follow-up, 652 days; range 2-3460 days). RESULTS: Both hypoglycemia during the initial intravenous insulin therapy phase (observed in 26.5% of patients) and hypoglycemia during the later subcutaneous insulin therapy phase (observed in 52.7% of patients) were associated with long-term mortality. After adjusting for potential confounders, hypoglycemia during the initial intravenous insulin therapy phase remained associated with mortality (hazard ratio 2.10, 95% CI 1.27-3.46, p = 0.004). CONCLUSIONS: Hypoglycemia during hyperosmolar hyperglycemic crises is a marker of long-term mortality, especially when it occurs during the initial intravenous insulin therapy phase.

Differences between GH and PRL co-secreting and GH-secreting pituitary adenomas. A series of 604 cases.

PURPOSE: To evaluate differences in clinical presentation and in surgical outcomes between growth hormone-secreting pituitary adenomas (GH-PAs) and GH and prolactin co-secreting pituitary adenomas (GH&PRL-PAs). METHODS: Multicenter retrospective study of 604 patients with acromegaly submitted to pituitary surgery. Patients were classified into two groups according to serum PRL levels at diagnosis and immunohistochemistry (IHC) for PRL: a) GH&PRL-PAs when PRL levels were above the upper limit of normal and IHC for GH and PRL was positive or PRL levels were >100ng/and PRL IHC was not available (n=130) and b) GH-PAs who did not meet the previously mentioned criteria (n=474). RESULTS: GH&PRL-PAs represented 21.5% (n=130) of patients with acromegaly. The mean age at diagnosis was lower in GH&PRL-PAs than in GH-PAs (P<0.001). GH&PRL-PAs were more frequently macroadenomas (90.6% vs. 77.4%, P=0.001) and tended to be more invasive (33.6% vs. 24.7%, P=0.057) than GH-PAs. Furthermore, they had presurgical hypopituitarism more frequently (OR 2.8, 95% CI 1.83-4.38). IGF-1 upper limit of normality (ULN) levels at diagnosis were lower in patients with GH&PRL-PAs (median 2.4 [IQR 1.73-3.29] vs. 2.7 [IQR 1.91-3.67], P=0.023). There were no differences in the immediate (41.1% vs 43.3%, P=0.659) or long-term post-surgical acromegaly biochemical cure rate (53.5% vs. 53.1%, P=0.936) between groups. However, there was a higher incidence of permanent arginine-vasopressin deficiency (AVP-D) (7.3% vs. 2.4%, P=0.011) in GH&PRL-PAs patients. CONCLUSIONS: GH&PRL-PAs are responsible for 20% of acromegaly cases. These tumors are more invasive, larger and cause hypopituitarism more frequently than GH-PAs and are diagnosed at an earlier age. The biochemical cure rate is similar between both groups, but patients with GH&PRL-PAs tend to develop permanent postsurgical AVP-D more frequently.

Continuous Glucose Monitoring Alarms in Adults with Type 1 Diabetes: User Characteristics and the Impact of Hypoglycemia and Hyperglycemia Alarm Thresholds on Glycemic Control.

Background: Few studies have evaluated the implications of the alarm thresholds of continuous glucose monitoring (CGM) systems for individuals with diabetes. The present study aimed to investigate the influence of hypoglycemia and hyperglycemia alarm thresholds on glycemic control in adults with type 1 diabetes (T1DM) and the characteristics of patients who use these alarms more frequently. Methods: This observational cross-sectional study included 873 users of the FreeStyle Libre 2 system (501 men, median age 48 years, range 18-90 years) with T1DM from a single center. We investigated the role of demographic and metabolic factors on the use of alarms and the impact of hypoglycemia and hyperglycemia alarms and their thresholds on glycemic control. Results: Alarm users were older than nonusers (median age 49 vs. 43 years, respectively; P < 0.001). The hypoglycemia alarms were set by 76.1% of women and by 69.1% of men (P = 0.022). The hypoglycemia alarms reduced hypoglycemia features and glucose variability, although at the expense of shorter time in range. The higher the hypoglycemia alarm threshold, the greater these effects. The hyperglycemia alarms were effective in reducing hyperglycemia and lowering the glucose management indicator, although at the expense of a greater tendency to hypoglycemia. The lower the hyperglycemia alarm threshold, the greater these effects. Conclusions: CGM alarms contribute to better glycemic control. However, hypoglycemia and hyperglycemia alarms have advantages and disadvantages. Adults with T1DM should explore, under medical supervision, which alarm thresholds will best help them achieve their individual glycemic goals.

Hypoglycemia in patients with type 2 diabetes mellitus during hospitalization: associated factors and prognostic value.

BACKGROUND: The risk factors for hypoglycemia during hospital admission and its consequences in patients with diabetes are not entirely known. The present study aimed to investigate the risk factors for hypoglycemia, as well as the potential implications of hypoglycemia in patients with type 2 diabetes mellitus admitted to the hospital. METHODS: This retrospective cohort study included 324 patients (214 [66.0%] men; median age 70 years, range 34-95 years) with type 2 diabetes admitted to a university hospital who were consulted the Endocrinology Department for glycemic control during a 12-month period. We investigated the potential role of demographic factors, metabolic factors, therapy, and comorbidities on the development of in-hospital hypoglycemia. We explored the prognostic value of hypoglycemia on mortality (both in-hospital and in the long-term), hospital readmission in the following year, and metabolic control (HbA1c value) after discharge (median follow-up, 886 days; range 19-1255 days). RESULTS: Hypoglycemia occurred in 154 (47.5%) patients during their hospitalization and was associated with advanced age, previous insulin therapy, higher Charlson Comorbidity Index, lower body mass index and lower baseline HbA1c values. Hypoglycemia was associated with greater in-hospital and long-term mortality, longer hospital stays, higher readmission rates, and poorer metabolic control after discharge. These negative consequences of hypoglycemia were more frequent in patients with severe (≤ 55 mg/dL) hypoglycemia and in patients who had hypoglycemia during a greater percentage of hospitalization days. CONCLUSIONS: Hypoglycemia during hospital admission is a marker of a poor prognosis in patients with type 2 diabetes.

[Cetoacidosis diabética al diagnóstico de diabetes mellitus tipo 1 en Asturias entre 2011 y 2020: influencia de la duración de los síntomas en la prevalencia de cetoacidosis y en la pérdida de peso.] / Diabetic ketoacidosis at diagnosis of type 1 diabetes in Asturias (Spain) between 2011 and 2020: influence of symptom duration on prevalence of ketoacidosis and weight loss.

OBJECTIVE: Diabetic ketoacidosis (DKA) is a serious complication that usually occurs at diagnosis of type 1 diabetes mellitus (T1D). However, the prevalence of DKA at diagnosis of T1D is heterogeneous in different regions of the world. The aim of this study was to determine the prevalence of DKA at diagnosis of T1D in Asturias. METHODS: This study included all patients under nineteen years of age diagnosed with T1D in Asturias between 2011 and 2020. Retrospective review of medical records was performed to analyse DKA and other characteristics at diagnosis. A log binary regression model was constructed to obtain an estimate of the prevalence ratio of DKA to diagnosis in the years studied. RESULTS: A total of 267 people were diagnosed with a mean age of 9.85±4.46 years. The prevalence of DKA at diagnosis during this period was 38.63%. There was an increasing trend, with a prevalence ratio over the years studied of 1.015 (95%CI: 0.96-1.07; p=0.61). Duration of symptoms before diagnosis was 4.57±7.64 weeks. Weight loss was 7.56±7.26%, being more than 10% of previous weight in almost half of the patients who loosed weight. There was a positive relationship between symptoms duration and prevalence of DKA and between time to diagnosis and weight loss. CONCLUSIONS: Asturias has a high prevalence of DKA at diagnosis of T1D, slightly higher than observed in other studies at national level and higher than in other similar countries, with a tendency to increase. Delayed diagnosis is a key factor in the prevalence of DKA and weight loss. Thus, health actions are needed for the early detection of T1D to avoid DKA at diagnosis.

OBJETIVO: La cetoacidosis diabética (CAD) es una complicación grave que puede producirse al diagnóstico de la diabetes mellitus tipo 1 (DM1). La prevalencia de CAD al diagnóstico de DM1 es desigual en las distintas regiones del mundo. El objetivo de este estudio fue conocer la prevalencia de CAD al diagnóstico de DM1 en Asturias. METODOS: Se incluyeron los pacientes menores de diecinueve años diagnosticados de DM1 en Asturias entre 2011 y 2020. Mediante revisión de historia clínica se analizó la prevalencia de CAD así como otras características al diagnóstico. Se construyó un modelo de regresión log binaria para obtener una estimación de la razón de prevalencia de CAD al diagnóstico en los años estudiados. RESULTADOS: Se diagnosticaron 267 personas con edad media de 9,85±4,46 años. La prevalencia de CAD al diagnóstico fue del 38,63%. Se apreció una tendencia al aumento, con una razón de prevalencia en los años estudiados de 1,015 (IC95%:0,96-1,07; p=0,61). La duración de los síntomas hasta el diagnóstico fue de 4,57±7,64 semanas. La pérdida de peso fue de 7,56±7,26%, siendo superior al 10% en casi la mitad de los pacientes que perdieron peso. Se apreció relación entre la duración de los síntomas y la prevalencia de CAD, y entre el tiempo de evolución y la pérdida de peso. CONCLUSIONES: Asturias presenta una alta prevalencia de CAD al diagnóstico de DM1, levemente superior a otros estudios a nivel nacional y superior a otros países de nuestro entorno, con tendencia al aumento. El retraso diagnóstico es clave en la prevalencia de CAD y en la pérdida de peso. Son necesarias actuaciones sanitarias para la detección precoz de la DM1.

Survey of Spanish hospitals on diabetes care resources.

INTRODUCTION: The quality of diabetes care varies from region to region. The objective of this study is to analyze the characteristics of care in different hospitals in Spain through a specific survey assessing different aspects of care for both children and adults. MATERIALS AND METHODS: Cross-sectional observational voluntary survey study, sent to the heads of the Endocrinology and Pediatric Endocrinology Departments or Units in public hospitals with more than 150 beds, during the first semester of 2021. A total of 105 responses were obtained, 55.5% of the 189 requested, which corresponded to a population served of 31,782,409 people, representing almost 80% of the total population served. RESULTS: Patients with diabetes under 15 years of age are cared for by Pediatric Departments, but only 58% of them have a specific Diabetes Education Unit for children, and in 72% of the cases, there is one single nurse dedicated to these tasks, and not always full-time. Those over 15 years of age are attended by specialists in Endocrinology and Nutrition in 94.3 % of hospitals. There are Therapeutic Education Units in Diabetes in practically all hospitals (94.3%). However, Diabetes Day Hospitals exist in only 32 centres and cover 40.3% of the population, since in 22 provinces there are none. Virtual and telematic consultations, as well as retinography, are available in more than 70% of cases, but access to a Diabetic Foot Unit only in 54% of centres. Monographic technological consultations on diabetes have become widespread, but access to mental health specialists with diabetes training remains limited (24% of centres), and interdisciplinary (32%) or interlevel (12%) committees are very scarce. CONCLUSION: Diabetes care in Spain shows great variability from one region to another, and some deficiencies have been detected that affect a large part of the population, such as access to Diabetic Foot Units, as well as mental health specialists with specific training. The presence of multidisciplinary and mixed committees between levels of care remains scarce.

Reclassification of type 2 diabetes to type 1 diabetes in Asturias (Spain) between 2011 and 2020.

BACKGROUND: Differentiating between type 1 diabetes (T1D) and type 2 diabetes (T2D) can be difficult in adults. The aim of this study was to determine the frequency of diagnostic reclassification from T2D to T1D, the characteristics of the patients and the impact on the management of the disease. METHODS: Observational and descriptive study including patients diagnosed with T1D in Asturias (Spain) between 2011 and 2020 who had been considered as T2D for at least 12 months. RESULTS: A total of 205 patients were included, representing 45.3% of those diagnosed with T1D over 30 years of age. Median time of evolution as T2D was 7,8 years. The age was 59.1 ± 12.9 years. BMI was > 25 kg/m2 in 46.8% of patients. HbA1c was 9.1 ± 2.1%, 77 ± 22 mmol/mol, and 56.5% were using insulin. Pancreatic antibodies were present in 95.5%, the most frequent being GAD, 82.6%. At 6 months, basal insulin use increased from 46.9 to 86.3%, and HbA1c decreased, 9.2 ± 2.0%vs7.7 ± 1.2%, 77 ± 22vs60 ± 13 mmol/mol; p < 0.0001. CONCLUSIONS: Diagnosis as T2D in patients with T1D in adults is common. Age, BMI, insulin use and other clinical features are not definitely discriminatory. GAD is the antibody of choice in case of diagnostic suspect. Reclassification has important implications for metabolic control.

Iodine status in pregnant women in northern Spain. Effect of iodised salt and iodine supplements on thyroid function.

INTRODUCTION: Iodine deficiency is linked to thyroid dysfunction, particularly in pregnant women. The objective of this study was to ascertain the iodine levels of women in the second trimester of pregnancy, analysing the influence of iodine ingestion on urinary iodine concentration (UIC) and maternal thyroid function. METHODS: A prospective observational study of pregnant women from Health Area IV of Asturias (northern Spain) recruited before 13 weeks of gestation between May and June 2017. A questionnaire on iodine intake was completed at the first visit, and urine and serum samples were collected at baseline and again during the second trimester. UIC, thyroid stimulating hormone (TSH) and free thyroxine (FT4) obtained in the second trimester of gestation were analysed and related to iodine intake. Thyroid autoimmunity was also analysed in half of the pregnant women at baseline. RESULTS: A total of 241 pregnant women were studied. Of these, 56.7% used iodised salt, 46.7% consumed ≥2 servings of dairy products daily and 88.1% took iodine supplements. Median UIC was 191µg/l (135.3-294µg/l), with 68.1% of the women having UIC ≥150µg/l. Only iodised salt consumption provided protection against iodine deficiency (odds ratio 0.35 [0.20-0.63], p=0.001). In women with no autoimmune thyroid disease (n=88), mean levels of TSH were lower in those that consumed iodised salt than in those that did not (respectively, 2.08±0.89mIU/l vs. 2.56±1.02mIU/l, p=0.025). In women with autoimmune thyroid disease (n=30), mean levels of TSH were higher in those that took iodine supplements than in those that did not (respectively, 2.97±1.25mIU/l vs. 1.16±0.41mIU/l, p=0.002). CONCLUSIONS: The pregnant women studied from Health Area IV in Asturias maintain adequate nutritional iodine status in the second trimester of gestation. In our sample, only the consumption of iodised salt was associated with adequate iodine nutrition, without affecting maternal thyroid function. Most of the women used iodine supplements, which was linked to higher levels of TSH in pregnant women with autoimmune thyroid disease.

Incidence of type 1 diabetes mellitus in Asturias (Spain) between 2011 and 2020.

INTRODUCTION: Type 1 diabetes mellitus (DM1) is a chronic disease with important socio-health repercussions that requires epidemiological information for proper health management. The aim of this study was to determine the incidence of DM1 in Asturias between 2011-2020. METHODS: Descriptive study which included diagnoses of DM1 in Asturias between 2011-2020 captured as a primary source by reviewing the register of pancreatic autoimmunity analysis. Incidence rates were estimated, expressed per 100,000 population-years of risk by age group, sex, and health area. RESULTS: A total of 815 patients were diagnosed, 53.13% men. The mean age was 34.32±22.07 years; 9.85±4.46 in children under 19 years of age (10.48±4.45 in males and 9.00±4.36 in females). Of the diagnoses, 55.34% occurred at an age over 30 years. The incidence was 7.82 (7.29-8.37); 19.65 (17.17-22.39) in under 15s and 12.84 (11.73-14.03) in under 40s. The maximum incidence peak was between 10-14 years, both in males 31.16 (23.89-39.95) and in females 21.72 (15.59-29.47). There was no significant increase in incidence over the years studied. CONCLUSIONS: Asturias has a high incidence of DM1. In our study no earlier age at diagnosis was observed or an increase in incidence. Compared to previous studies, the increase in incidence is most likely due to an improvement in data capture, not to a real increase in incidence. A high percentage of diagnoses occur in adulthood.

Mortality in Acromegaly Diagnosed in Older Individuals in Spain Is Higher in Women Compared to the General Spanish Population.

CONTEXT: There are no data on mortality of acromegaly diagnosed in older individuals. OBJECTIVE: This work aimed to compare clinical characteristics, growth hormone-related comorbidities, therapeutic approaches, and mortality rate of patients diagnosed before or after 2010 and to assess overall mortality rate compared with the general Spanish population. METHODS: A retrospective evaluation was conducted among Spanish tertiary care centers of 118 patients diagnosed with acromegaly at age 65 or older. Kaplan-Meier curves were constructed to trace survival, and Cox proportional hazard models were used to assess the risk factors associated with mortality. We also compared mortality with that of the Spanish population by using age- and sex-adjusted standardized mortality ratios (SMRs). RESULTS: No differences were found in first-line treatment or biochemical control, between both periods except for faster biochemical control after 2010. Twenty-nine (24.6%) patients died, without differences between groups, and had a median of follow-up 8.6 years (103, [72.3] months). Overall SMR was 1.02 (95% CI, 0.57-1.54), (0.60; 95% CI, 0.35-1.06) for men and (1.80; 95% CI, 1.07-2.94) for women. The most common cause of death was cardiovascular disease (CVD). CONCLUSION: The mortality in patients with acromegaly diagnosed in older individuals was no different between both periods, and there was no overall SMR difference compared with the general Spanish population. However, the SMR was higher in women. As CVD is the leading cause of mortality, it seems advisable to initiate an intense CVD protective treatment as soon as acromegaly is diagnosed, particularly in women, in addition to tight acromegaly control to prevent excess mortality.

miR-24-3p and Body Mass Index as Type 2 Diabetes Risk Factors in Spanish Women 15 Years after Gestational Diabetes Mellitus Diagnosis.

Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance that is diagnosed for the first time during pregnancy. The objective of this study is to know the glucose tolerance status after 15 years of pregnancy in patients diagnosed with gestational diabetes and to assess the long-term effect of GDM on the circulating miRNA profile of these women. To answer these, 30 randomly selected women diagnosed with GDM during 2005-2006 were included in the study, and glucose tolerance was measured using the National Diabetes Data Group criteria. Additionally, four miRNAs (hsa-miR-1-3p, hsa-miR-24-3p, hsa-miR-329-3p, hsa-miR-543) were selected for their analysis in the plasma of women 15 years after the diagnosis of GDM. In our study we discovered that, fifteen years after the diagnosis of GDM, 50% of women have some degree of glucose intolerance directly related to body weight and body mass index during pregnancy. Dysglycemic women also showed a significantly increased level of circulating hsa-miR-24-3p. Thus, we can conclude that initial weight and BMI, together with circulating expression levels of hsa-miR-24-3p, could be good predictors of the future development of dysglycemia in women with a previous diagnosis of GDM.
