Real-World Evidence of Off-Label Use of Commercially Automated Insulin Delivery Systems Compared to Multiple Daily Insulin Injections in Pregnancies Complicated by Type 1 Diabetes.

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.

Déficit neurológico durante un episodio de cetoacidosis diabética e hiperosmolaridad en una paciente con diabetes tipo 1 y nefropatía diabética / Neurological signs during an episodie of ketoacidosis and hyperosmolarity in a type 1 diabetic patient with diabetic nephropathy

La alteraciones neurológicas en situaciones de hiperglucemia aguda están favorecidas por la hiperosmolaridad plasmática. Presentamos el caso de una paciente de 32 años con diabetes mellitus tipo 1 (DM1) de 23 años de evolución, mal control metabólico habitual e insuficiencia renal crónica (aclaramiento de creatinina, 35 ml/min), que ingresó en el servicio de urgencias con deterioro cognitivo y hemiparesia izquierda durante un episodio de cetoacidosis diabética e hiperosmolaridad. La aparición de hiperosmolaridad en un paciente con DM1 es poco frecuente, más aún si tiene insuficiencia renal que conlleva disminución de la diuresis osmótica y, por lo tanto, el desarrollo de hiperosmolaridad (AU)

Plasma hyperosmolarity increases the likelihood of neurological symptoms in acute hyperglycemia. We report the case of a 32-year-old woman with type 1 diabetes for 23 years, poor metabolic control and chronic kidney disease (creatinine clearance rate: 35 ml/min) who presented to the emergency department with depressed sensorium and left-sided hemiparesis during an acute episode of diabetic ketoacidosis and hyperosmolarity. Hyperosmolar coma in type 1 diabetic patients is uncommon, especially if there is renal impairment leading to reduced osmotic diuresis and the development of hyperosmolarity (AU)

Tratamiento con radioyodo en el hipertiroidismo: resultados a largo plazo / Radioiodine in hyperthyroidism: long-term outcomes

Introducción: El 131I es una opción terapéutica eficaz para el tratamiento del hipertiroidismo, aunque en un alto porcentaje de pacientes se desarrolla hipotiroidismo definitivo. Objetivo: Evaluar la función tiroidea a largo plazo de pacientes con hipertiroidismo tras el tratamiento con 131I. Pacientes y método: Se estudió retrospectivamente a 128 pacientes hipertiroideos que recibieron 131I entre 1994 y 1999. Se excluyó a 32 por pérdida en el seguimiento y se clasificó a los 96 sujetos incluidos, según la afección tiroidea, en GB (Graves-Basedow, n = 46), BMN (bocio multinodular, n = 35) y AT (adenoma tóxico, n = 15). El tiempo de seguimiento fue 7,3 ± 0,2 años y la dosis media de 131I, 12,2 ± 0,3 mCi. Resultados: De los 96 pacientes, en el 58,3% se desarrolló hipotiroidismo, el 34,4% mantenía normofunción tiroidea y el 7,3% restante permanecía con hiperfunción clínica o subclínica. El 19,8% (n = 19) precisó más de una dosis de 131I. En el grupo GB, el 87% evolucionó a hipotiroidismo, el 10,9% persistía eutiroideo y el 2,1%, con hiperfunción; recibieron 2 dosis de 131I 10 (21,7%) pacientes. Del grupo BMN, el 28,6% quedó hipotiroideo; el 54,3%, eutiroideo y el 17,1%, con hiperfunción; 7 (20%) pacientes necesitaron 2 dosis y 2 (5,7%) pacientes, 3 dosis. En el grupo AT, el 40% desarrolló hipotiroidismo y el 60% mantenía normofunción tiroidea; 2 (13,3%) pacientes recibieron 2 dosis. Conclusiones: La tasa de hipotiroidismo definitivo en el grupo GB es superior a la de los otros 2 grupos. El alto porcentaje de pacientes con BMN que persisten hipertiroideos tras 131I indica que son necesarias dosis superiores en este grupo

Background: Radioiodine treatment is a safe and effective therapeutic option for hyperthyroidism, although the incidence of subsequent definitive hypothyroidism is high. Objective: To evaluate long-term thyroid function after radioiodine treatment in hyperthyroid patients. Patients and method: We performed a retrospective study of 128 hyperthyroid patients administered 131I between 1994 and 1999. We excluded 32 patients who were lost to follow-up. The 96 patients included were categorized into Graves' disease (GD), n = 46, toxic multinodular goiter (TMG), n = 35, and toxic adenoma (TA), n = 15. The mean time of follow-up was 7.3 ± 0.2 years and the mean 131I dose was 12.2 ± 0.3 mCi. Results: Among the 96 patients, hypothyroidism developed in 58.3%, normal thyroid function was achieved in 34.4% and some degree of hyperthyroidism persisted in 7.3%. More than one radioiodine dose was required in 19.8% (n = 19). In GD patients, hypothyroidism appeared in 87%, euthyroidism was achieved in 10.9%, and hyperthyroidism persisted in 2.1%. Ten patients required second 131I doses. In the TMG group, hypothyroidism developed in 28.6%, euthyroidism was achieved in 54.3% and hyperthyroidism was present in 17.1%. Seven patients (20%) were administered a second radioiodine dose and two patients (5.7%) received a third dose. In the TA group, hypothyroidism developed in 40% and euthyroidism was achieved in 60%. Two patients (13.3%) received a second 131I dose. Conclusions: The incidence of definitive hypothyroidism was higher in the GD group than in the TMG and TA groups. The high percentage of TMG patients with persistent hyperthyroidism suggests the need for higher radioiodine doses in this group
