Concentraciones séricas de colesterol y triglicéridos en pacientes diabéticos con hipotiroidismo subclínico

ObjectiveTo assess whether subclinical hypothyroidism is associated to elevations in serum cholesterol and triglyceride levels in patients with type 2 diabetes.Patients and methodsFrom a total population of 1,112 patients with type 2 diabetes screened for thyroid dysfunction (thyrotropin measurement), a group of 325 patients with normal thyroid function and another group of 29 patients with subclinical hypothyroidism were selected. No patient had known dyslipidemia or was taking lipid lowering medication.ResultsPatients with subclinical hypothyroidism had serum levels of total cholesterol (4.88 ± 0.74 mmol/L), HDL cholesterol (1.37 ± 0.34 mmol/L), LDL cholesterol (2.94 ± 0.58 mmol/L), and triglycerides (1.05 [0.88-1.41] mmol/L) that did not significantly differ from those found in euthyroid patients (4.79 ± 0.83, 1.33 ± 0.36, 2.87 ± 0.76, and 1.11 [0.81-1.43] mmol/L, respectively). Multiple regression analysis showed no association between TSH and serum lipid levels.ConclusionThese results suggest that, in our population, there are no significant differences in serum cholesterol and triglyceride levels between diabetic patients with normal and reduced thyroid function.     

Pauta óptima de administración de insulina detemir en sujetos diabéticos tipo 1 con mal control metabólico

AimTo compare different administration times of insulin detemir (IDet) in patients with type 1 diabetes and poor metabolic control.Material and MethodsThis 24-week open study included 39 people with type 1 diabetes mellitus (DM) randomized to one injection of IDet before lunch (mean 14.24 ± 00.36 (± SD) h) or at bedtime (23.19 ± 0.42 h). Whenever target glycemia levels were not reached, the regimen was switched to insulin therapy with two injections (IDet-12 h). Insulin aspart was used before main meals.ResultsAt week 24, only 12.2% of patients remained in the IDet bedtime group and 30.3% in the IDet before lunch group. The remaining 57.5% joined the IDet-12 h group. There were no differences between the IDet before lunch and IDet bedtime groups. A subanalysis including the three groups demonstrated better metabolic control in the IDet before lunch group (glycosylated hemoglobin (HbA1c) 7.1 ± 0.2 vs. 7.6 ± 0.4 and 8.1 ± 0.2% in IDet before-lunch, IDet bedtime and IDet-12 h, respectively; p<0.05). An HbA1c value below 7% was achieved in 30.3% of the patients: 15.2% in the IDet before-lunch group, 3.3% in the IDet bedtime group and 12.2% in IDet-12 h group. Quality of life did not differ among treatment groups.ConclusionsOne injection of IDet administered before lunch could improve metabolic control. However, most patients required two injections of IDet.     

Efectos del tratamiento con ácido zoledrónico en pacientes adultos con osteogénesis imperfecta

Background and objectiveOsteogenesis imperfecta (OI) is a genetic disorder that results in bone fragility. Several studies have demonstrated the effectiveness of bisphosphonate therapy. The aim of this study was to evaluate the effects of intravenous zoledronic acid on bone mineral density (BMD) and biochemical markers of bone turnover in adults with OI.Material and methodsWe carried out a prospective non-randomized study in patients with osteoporosis or severe osteopenia (T score <?2) related to OI and intolerance or contraindication to oral bisphosphonates. The patients were treated with a zoledronic acid infusion every 6 months. Densitometry was carried out annually. Calcium (Ca), phosphate (P), intact parathormone (PTH), 25 hydroxyvitamin D and biochemical markers of bone turnover [bone alkaline phosphatase (BAP), beta-cross-laps (CTX) and urinary deoxypyridoxine (DOP)] were measured every year. Adverse events and new fractures were registered.ResultsTen patients (2 men and 8 women) were treated. Treatment increased BMD measured in the lumbar spine after 24 (0.738±0.141 vs 0.788±0.144 g/cm²; p=0.048) and 36 months (0.720±0.139 vs 0.820±0.128; p=0.01). Significant increases in BMD were also observed after 24 months in the femoral neck (0.677±0.121 vs 0.703±0.122 g/cm²; p<0.016). Serum Ca, P, BAP and CTX concentrations remained unchanged. PTH concentrations increased and vitamin D concentrations decreased after 36 months of treatment. DOP excretion decreased significantly after 24 months. Seven patients had mild influenza-like symptoms occurring within the first 24 h after the first infusion. No severe adverse events were observed. None of the patients had new fractures.ConclusionZoledronic acid seems to be a safe and effective treatment option in adults with osteoporosis related to OI.     

Mortalidad en pacientes con demencia que cursaron internación en unidades de cuidados críticos

ObjectiveTo determine the mortality and comorbidities associated of patients with dementia admitted to the Intensive Care Unit (ICU) on the hospitalization and at one year of follow-up.Materials and methodsA retrospective observational cohort study was carried out between 2012 and 2017 at the Hospital Italiano de San Justo, of patients who were admitted to the ICU, these were observed up to hospitalary death, out hospital death one year of hospitalization, the disenrollment from the institution's health plan or the end of the follow-up.ResultsA total of 163 patients were included for analysis. We recorded those 79 patients (48.47%) died one year after the hospitalization, of them 25 (15.34%) in ICU and 8 (4.91%) in general room. The most frequent causes of death were respiratory. The factors most associated with mortality were: orotracheal intubation (HR = 2.01; 95% CI: 1.11-3.65; P = .02), history of leukemia (HR = 8.55; 95% CI: 1.82-40.05; P ≤ .05), elevated Charlson (HR = 1.16, 95% CI: 1.04-1.41; P = .05), and elevated APACHE II at admission (HR = 1.07; 95% CI: 1.03-1.11; P ≤ .05).ConclusionsThe present study expresses the prognosis of patients with a diagnosis of dementia admitted to the ICU and that depends not only on their baseline neurological status but also on the severity at admission and comorbidities.     

Caracterización y costes asociados al perfil del paciente con diabetes tipo 2 en tratamiento con metformina al que se le añade un segundo fármaco antidiabético oral: estudio de base poblacional

ObjectivesTo determine compliance, metabolic control, complications and healthcare costs of patients treated with metformin started a second antidiabetic drug in patients with type 2 diabetes (T2DM).Patients and methodsDesign multicenter observational retrospective. Patients were evaluated ≥30 years (age), treated with metformin and started a second antidiabetic treatment during 2008-2009. There were 4 patient groups (metformin and another antidiabetic): a) dipeptidyl peptidase-4 inhibitors (IDPP4), b) sulfonylureas, c) glitazones and d) insulin. Main measures: comorbidity, metabolic control, compliance and complications. Patients were followed for 2 years. The cost model differed direct health costs (primary care / specialist) and indirect (labor productivity). Statistical analysis: logistic regression models and ANCOVA, p < 0.05.Results2067 patients were included (mean age: 66.6 years male: 53.1%). 25.1% started a second treatment with IDPP4; 42.9% sulfonylureas, 14.0% glitazones and 18.0% insulin. At 2 years follow-up, patients treated with IDPP4 showed greater adherence vs. 70.3%. 59.9%, 60.3% and 58.4; better control of 64.3% vs. DM2. 62.6%, 62.8% and 50.5% and a decrease of 13.9% compared to hypoglycaemia 40.4%, 37.6% and 58.9% respectively (p < 0.001). The average / unit total costs was €2,321 vs. €2,475, €2,724 and €3,164, respectively, p < 0.001. Rates of cardiovascular events and renal failure were 3.7%, 6.4%, 7.6% and 10.2% respectively.ConclusionsSulfonylureas were the most commonly used drugs. Patients treated with IDPP4 had higher compliance and control of diabetes, with lower rates of hypoglycaemia and healthcare costs.

The limitation of therapeutic effort (LTE) depends on medical, ethical and individual factors. We describe the characteristics of patients with bacteremia in which it was decided to limit the therapeutic effort.

Costes directos sanitarios y resultados clínicos tras el inicio del tratamiento con insulina en pacientes con diabetes mellitus tipo 2 en España: datos de 24 meses de seguimiento del estudio INSTIGATE

Background and objectiveThe INSTIGATE study assessed healthcare costs and clinical outcomes in patients with type 2 diabetes mellitus starting insulin therapy in Spain over a 24-month follow up period.Material and methodsThis was an observational, non-interventional, prospective, multicenter study. Costs incurred in the previous 6 months were assessed at each visit.ResultsA total of 172 patients with a mean body mass index of 29.6 kg/m², a mean [standard deviation] duration of diabetes of 10.9 [7.0] years and a hemoglobin A_1c value of 9.2% [1.5%] were followed up for at least 12 and up to 24 months. Direct costs were assessed from the perspective of the Spanish healthcare system. Long/intermediate-acting insulin alone was started in 116 patients (67.4%). After 6, 12, and 24 months of insulin treatment, mean [SD] intraindividual changes from baseline in hemoglobin A_1c were -1.9% [1.65%], -1.6 [1.73%], and -1.5% [1.76%] respectively. Mean (median) total diabetes-related healthcare costs per patient increased from €659 (€527) to €1.085 (€694) 6 months after insulin initiation, decreased to €646 (€531) after 12 months, and increased again after 24 months to €667(€539). Insulin/oral antidiabetics, primary/specialized care, and blood glucose monitoring accounted for 41%, 26%, and 19% of total cost at 24 months respectively.ConclusionsClinical parameters of these patients with type 2 diabetes mellitus improved following insulin initiation. After a temporary increase, direct healthcare costs of diabetes care returned to baseline values at the end of the follow-up period.     

Calidad de vida y satisfacción con el tratamiento de sujetos con diabetes tipo 2: resultados en España del estudio PANORAMA

ObjectivesFew studies are available on quality of life and treatment satisfaction of patients with type 2 diabetes mellitus (T2DM). Both of them were the primary objectives of the PANORAMA (NCT00916513) study. Metabolic control, treatment patterns, and management by healthcare professionals were also evaluated.Material and methodsThis multicenter, cross-sectional, observational study randomly recruited>40 year-old patients with T2DM from Spanish healthcare centers. HbA1c was measured using the same technique in all patients, who also completed quality of life (EQ-5D and ADDQoL) and treatment satisfaction (DTSQ) questionnaires and the Hypoglycemia Fear Survey (HFS-II).ResultsFifty-four investigators recruited 751 patients, 60.3% of whom had HbA1c levels <7%. Approximately 25% of patients on monotherapy had HbA1c values ≥ 7%, Patients with longer disease duration and more complex treatments, especially with insulin, showed the poorer control. Despite good overall treatment satisfaction (mean 29.3±6.1, 0 to 36-point scale), patients with a poorer metabolic control, previous hypoglycemia episodes, and more complex therapies had a worse QoL and a greater fear of suffering hypoglycemia.ConclusionsDespite advances in metabolic control, there are still areas to improve. Early addition of safe drugs to monotherapy would help achieve control objectives without increasing the risk of hypoglycemia, and delaying the start of insulin therapy. This would also improve QoL and treatment satisfaction.     

Evaluación del grado de consecución de objetivos de control metabólico en pacientes con diabetes mellitus tipo 2

ObjectiveTo evaluate the extent to which metabolic targets in type 2 diabetes (DM-2) are achieved in the Endocrinology and Clinical Nutrition Unit of the Hospital Puerta del Mar in Cadiz (Spain) from 2005 to 2008.MethodThe database included in the computer application HP-Doctor used for all patients attended in our unit (admissions, consultations and peripheral centers) was analyzed. All patients with a principal or secondary diagnosis of DM-2 were included. Clinical characteristics, chronic complications, drug treatment and the percentage of patients who achieved annual mean targets of glycosylated hemoglobin (HbA1c) and low-density lipoprotein cholesterol (LDLc) were analyzed.ResultsFrom 2005 to 2008, the number of DM-2 patients with computerized records increased by 108.7%. In 2008, 1,177 patients were evaluated. A total of 10.8% were active smokers, 53% had hypertension, and 51.2% and 12.6% presented with retinopathy and cardiovascular disease, respectively. During the study period, the percentage of patients with a mean HbA1c <7% was similar (2005: 31.7% 2008: 30.4%), those with LDLc <100 mg/dl increased from 19.2% to 25.6% and only 9.2% of patients achieved both targets, HbA1c <7% and LDLc <100 mg/dl.ConclusionsIn 2008, only 30% of DM-2 patients achieved a mean HbA1c < 7% and only 25% had LDLc < 100 mg/dl. Metabolic control in DM-2 patients should be improved.
