Benefit of tolvaptan in the management of hyponatraemia in patients with diuretic‐refractory congestive heart failure: the SEMI‐SEC project

Aims: Hyponatraemia is an electrolyte disorder that occurs in advanced congestive heart failure (HF) and worsens prognosis. We explored the usefulness of tolvaptan, which has shown promising results in the treatment of this condition. Methods and results: This study is based on a retrospective national registry (2011-15) of patients hospitalized with refractory HF and hyponatraemia who agreed to receive tolvaptan when standard treatment was ineffective. The benefit of tolvaptan was analysed according to the following criteria: normalization ([Na+] >= 135mmol/L) or increased sodium levels [Na+] >= 4mEq/L on completion of treatment, and increase in urine output by 300 or 500mL at 48h. Factors associated with tolvaptan benefit were explored. A total of 241 patients were included, 53.9% of whom had ejection fraction = 4mEq/L and/or +300mL in urine output (54.4% both). Conclusions: An increase in sodium levels and/or improvement in urine output was observed in patients admitted for HF and refractory hyponatraemia under tolvaptan treatment. Tolvaptan may be useful in this setting, in which no effective proven alternatives are available

De-novo non-convulsive status epilepticus in adult medical inpatients without known epilepsy: Analysis of mortality related factors and literature review

BACKGROUND: Non-convulsive status epilepticus (NCSE) often goes unnoticed and is not easily detected in patients with a decreased level of consciousness, especially in older patients. In this sense, lack of data in this population is available. AIMS: The aim of the present study was to examine daily clinical practice and evaluate factors that may influence the prognosis of NCSE in non-epileptic medical inpatients. METHODS: We conducted a retrospective analysis including patients admitted by any cause in an Internal Medicine ward. All patients with compatible symptoms, exclusion of other causes, clinical suspicion or diagnosis of NCSE, and compatible EEG were included. Patients with a previous diagnosis of epilepsy were excluded. We also conducted a literature review by searching the PubMed/Medline database with the terms: Nonconvulsive Status OR Non-Convulsive Status. RESULTS: We included 54 patients, mortality rate reached 37% and the main factors linked to it were hypernatremia (OR = 16.2; 95% CI, 1.6-165.6; P = 0.019) and atrial fibrillation (OR = 6.7; 95% CI, 1.7-26; P = 0.006). There were no differences regarding mortality when comparing different diagnosis approach or treatment regimens. Our literature review showed that the main etiology of NCSE were neurovascular causes (17.8%), followed by antibiotic treatment (17.2%) and metabolic causes (17%). Global mortality in the literature review, excluding our series, reached 20%. DISCUSSION: We present the largest series of NCSE cases in medical patients, which showed that this entity is probably misdiagnosed in older patients and is linked to a high mortality. CONCLUSION: The presence of atrial fibrillation and hypernatremia in patients diagnosed with NCSE should advise physicians of a high mortality risk

Tratamiento de la hiponatremia secundaria al síndrome de secreción inadecuada de la hormona antidiurética: algoritmo multidisciplinar

Introducción: El síndrome de secreción inadecuada de la hormona antidiurética (SIADH) es la causa más frecuente de hiponatremia en el paciente hospitalizado. Sin embargo, faltan protocolos y algoritmos concretos que faciliten su abordaje terapéutico. Nuestro objetivo fue el desarrollo de dos algoritmos de tratamiento de la hiponatremia secundaria al SIADH en el paciente ingresado. Material y método: Un grupo multidisciplinar español compuesto por 2 especialistas en Endocrinología, 1 en Farmacia Hospitalaria, 2 en Medicina Interna y 2 en Nefrología se reunieron durante un año, bajo la tutela del grupo español del European Hyponatremia Network, y de las respectivas sociedades científicas españolas. Las pautas terapéuticas propuestas fueron basadas en recomendacio- nes ampliamente aceptadas, la práctica de expertos, guías de consenso, así como en la experiencia clínica de los autores. Resultados: Se elaboraron dos algoritmos de tratamiento. El Algoritmo 1 se dirige al tratamiento de la hiponatremia aguda como urgencia médica de abordaje inmediato, y es de aplicación al tratamiento de la hiponatremia grave tanto de tipo euvolémico como hipovolémico. Se basa en el uso de sueros salinos hipertónicos al 3 % i.v., con pautas de infusión y monitorización. Se expone cómo evitar la hipercorrección de la natremia y cómo corregirla en su caso. El Algoritmo 2 aborda el tratamiento de la hiponatremia no aguda leve o moderada asociada al SIADH. Expone cómo y cuándo usar la restricción hídrica, solutos, furosemida y tolvaptán, para alcanzar eunatremia en el paciente con SIADH. Conclusiones: Se han elaborado dos estrategias complementarias para el tratamiento de la hiponatremia inducida por SIADH, en un intento de fomentar la toma de conciencia acerca de esa patología, simplificar su abordaje y su tratamiento y, así, mejorar su pronóstico

Antithrombotic treatment in elderly patients with atrial fibrillation: a practical approach

Background: Atrial fibrillation (AF) in the elderly is a complex condition. It has a direct impact on the underuse of antithrombotic therapy reported in this population. Discussion: All patients aged >= 75 years with AF have an individual yearly risk of stroke > 4 %. However, the risk of hemorrhage is also increased. Moreover, in this population it is common the presence of other comorbidities, cognitive disorders, risk of falls and polymedication. This may lead to an underuse of anticoagulant therapy. Direct oral anticoagulants (DOACs) are at least as effective as conventional therapy, but with lesser risk of intracranial hemorrhage. The simplification of treatment with these drugs may be an advantage in patients with cognitive impairment. The great majority of elderly patients with AF should receive anticoagulant therapy, unless an unequivocal contraindication. DOACs may be the drugs of choice in many elderly patients with AF. Summary: In this manuscript, the available evidence about the management of anticoagulation in elderly patients with AF is reviewed. In addition, specific practical recommendations about different controversial issues (i.e. patients with anemia, thrombocytopenia, risk of gastrointestinal bleeding, renal dysfunction, cognitive impairment, risk of falls, polymedication, frailty, etc.) are provided

Atrial fibrillation as a new prognosis factor in chronic patients after hospitalization: the CHRONIBERIA index

A collaborative project in different areas of Spain and Portugal was designed to find out the variables that influence the mortality after discharge and develop a prognostic model adapted to the current healthcare needs of chronic patients in an internal medicine ward. Inclusion criteria were being admitted to an Internal Medicine department and at least one chronic disease. Patients’ physical dependence was measured through Barthel index (BI). Pfeiffer test (PT) was used to establish cognitive status. We conducted logistic regression and Cox proportional hazard models to analyze the influence of those variables on one-year mortality. We also developed an external validation once decided the variables included in the index. We enrolled 1406 patients. Mean age was 79.5 (SD = 11.5) and females were 56.5%. After the follow-up period, 514 patients (36.6%) died. Five variables were identified as significantly associated with 1 year mortality: age, being male, lower BI punctuation, neoplasia and atrial fibrillation. A model with such variables was created to estimate one-year mortality risk, leading to the CHRONIBERIA. A ROC curve was made to determine the reliability of this index when applied to the global sample. An AUC of 0.72 (0.7–0.75) was obtained. The external validation of the index was successful and showed an AUC of 0.73 (0.67–0.79). Atrial fibrillation along with an advanced age, being male, low BI score, or an active neoplasia in chronic patients could be critical to identify high risk multiple chronic conditions patients. Together, these variables constitute the new CHRONIBERIA index

Rationale, design and preliminary results of the GALIPEMIAS study (prevalence and lipid control of familial dyslipidemia in Galicia, northwest Spain)

[Abstract] Aims. There is little information on the familial nature of dyslipidemias in the Spanish population. This knowledge could have potential diagnostic and treatment implications. The objective of the GALIPEMIAS study was to determine the prevalence of familial dyslipidemia in Galicia, as well as determine the degree of lipid control in the participants. Prevalence of atherosclerotic cardiovascular disease (ASCVD) was also estimated. This paper presents the design, methodology and selected preliminary results. Methodology. A cross‐sectional study was performed in the population aged ≥18 years using cluster sampling and then random sampling. A sample of 1000 subjects was calculated and divided into three sequential phases with a specific methodology for each one. Phase I: selection of subjects from the general population and collection of informed consent documents; Phase II: collection of data from the digital clinical history to select subjects with dyslipidemia according to study criteria; Phase III: personal interview, blood analysis, family tree, and definitive diagnosis of dyslipidemia. Prevalence of different diseases and active medication was analysed. Corrected prevalence (to the reference population) of different risk factors and ASCVD was estimated. Results. Phase I participation was 89.5%. We extracted complete information from 93% of the participants (Phase II). According to the study′s own criteria, 56.5% (n = 527) of the participants had some form of dyslipidemia and almost 33.7% of them had familial dyslipidemia with autosomal dominant inherit pattern. The corrected prevalence of ASCVD was 5.1% (95% CI 3.1‐7.2). Conclusions. Dyslipidemia was the most prevalent cardiovascular risk factor in our population with an autosomal dominant inheritance pattern in one out of every three dyslipidemia cases. Approximately, 5.1% of the sample population aged ≥18 has suffered an episode of ACVD

Development and validation of a clinical score to estimate progression to severe or critical state in Covid-19 pneumonia hospitalized patients

The prognosis of a patient with Covid-19 pneumonia is uncertain. Our objective was to establish a predictive model of disease progression to facilitate early decision-making. A retrospective study was performed of patients admitted with Covid-19 pneumonia, classified as severe (admission to the intensive care unit, mechanic invasive ventilation, or death) or non-severe. A predictive model based on clinical, analytical, and radiological parameters was built. The probability of progression to severe disease was estimated by logistic regression analysis. Calibration and discrimination (receiver operating characteristics curves and AUC) were assessed to determine model performance. During the study period 1,152 patients presented with Covid-19 infection, of whom 229 (19.9%) were admitted for pneumonia. During hospitalization, 51 (22.3%) progressed to severe disease, of whom 26 required ICU care (11.4); 17 (7.4%) underwent invasive mechanical ventilation, and 32 (14%) died of any cause. Five predictors determined within 24 hours of admission were identified: Diabetes, Age, Lymphocyte count, SaO2, and pH (DALSH score). The prediction model showed a good clinical performance, including discrimination (AUC 0.87 CI 0.81, 0.92) and calibration (Brier score = 0.11). In total, 0%, 12%, and 50% of patients with severity risk scores ≤5%, 6-25%, and >25% exhibited disease progression, respectively. A simple risk score based on five factors predicts disease progression and facilitates early decision-making according to prognosis.Carlos III Health Institute, Spain, Ministry of Economy and Competitiveness (SPAIN) and the European Regional Development Fund (FEDER)Instituto de Salud Carlos II

Higher COVID-19 pneumonia risk associated with anti-IFN-α than with anti-IFN-ω auto-Abs in children

We found that 19 (10.4%) of 183 unvaccinated children hospitalized for COVID-19 pneumonia had autoantibodies (auto-Abs) neutralizing type I IFNs (IFN-alpha 2 in 10 patients: IFN-alpha 2 only in three, IFN-alpha 2 plus IFN-omega in five, and IFN-alpha 2, IFN-omega plus IFN-beta in two; IFN-omega only in nine patients). Seven children (3.8%) had Abs neutralizing at least 10 ng/ml of one IFN, whereas the other 12 (6.6%) had Abs neutralizing only 100 pg/ml. The auto-Abs neutralized both unglycosylated and glycosylated IFNs. We also detected auto-Abs neutralizing 100 pg/ml IFN-alpha 2 in 4 of 2,267 uninfected children (0.2%) and auto-Abs neutralizing IFN-omega in 45 children (2%). The odds ratios (ORs) for life-threatening COVID-19 pneumonia were, therefore, higher for auto-Abs neutralizing IFN-alpha 2 only (OR [95% CI] = 67.6 [5.7-9,196.6]) than for auto-Abs neutralizing IFN-. only (OR [95% CI] = 2.6 [1.2-5.3]). ORs were also higher for auto-Abs neutralizing high concentrations (OR [95% CI] = 12.9 [4.6-35.9]) than for those neutralizing low concentrations (OR [95% CI] = 5.5 [3.1-9.6]) of IFN-omega and/or IFN-alpha 2
