RESUMEN

The aim of this work is to examine our experience in the use of urea in patients with SIADH. Observational retrospective analysis of 48 patients with SIADH that have been treated with urea in a third-level hospital. Pre-post analysis of serum sodium levels. The 48 patients with SIADH had a median age of 78.5 (range 26-97 years). The serum sodium nadir was 119.8 ± 5.0 mmoL/L and at the beginning of treatment 125.6 ± 4.1 mmoL/L. The patients continued the treatment for a mean time of 2.95 ± 6.29 months, being the treatment still active in 4 patients. In all patients there was an improvement in serum sodium, being the final serum sodium at the end of treatment 134.4 ± 4.9 mmoL/L (p < 0.01). This improvement was observed from the first week. Adverse events were only detected in 2 patients with mild digestive symptomatology and 2 patients refused the treatment due to the low palatability of the urea. There was an economic cost reduction of 87.9% in comparison with treatment with tolvaptan. Urea has shown to be a safe and cost-effective option for the treatment of hyponatremia caused by SIADH.

RESUMEN

Aim: To assess the prevalence of malnutrition, frailty, and sarcopenia and the relationships between them in patients hospitalized for COVID-19. Methods: This was a cross-sectional study of the prevalence, determinants, and associations between malnutrition (GLIM 2019 criteria), sarcopenia (SARC-F scale, dynamometry, and calf circumference), and frailty (FRAIL scale) upon discharge following hospitalization for COVID 19. Results: A total of 101 patients (67.3% men, mean age 66.3 years) were recruited. Malnutrition was diagnosed in 49.5%, sarcopenia in 32.7%, and frailty in 28.7% of patients. Of the patients with malnutrition, 48% were also sarcopenic, and 42% were frail. There was a significant association between malnutrition and the severity of pneumonia according to the CURB-65 scale (odds ratio [OR] 2.61, p = 0.036), between sarcopenia and a Barthel score lower than 60 points (OR 29.52, p < 0.001), and between frailty and both a Barthel score lower than 60 points (OR 32.27, p < 0.001) and a length of hospital stay of over 30 days (OR 9.11, p = 0.008). Conclusions: Malnutrition, sarcopenia, and frailty are prevalent and interrelated entities in patients hospitalized for acute SARS CoV-2 infection, especially in patients with greater baseline functional impairment prior to admission and a higher infection severity.

RESUMEN

Se trata de un paciente con hipercolesterolemia familiar heterocigota y antecedentes de infarto agudo de miocardio, que es remitido a la unidad de lípidos de nuestro centro para ajuste del tratamiento hipocolesterolemiante. Dado que no alcanza los objetivos terapéuticos con tratamiento oral, comienza tratamiento con sesiones quincenales de aféresis de colesterol LDL, que mantiene durante 8 años. Con la introducción y disponibilidad de los inhibidores de la PCSK9, se presenta una nueva opción de tratamiento para este paciente

It is a patient with heterozygous familial hypercholesterolemia and a personal history of acute myocardial infarction, which is referred to our lipid unit for hypocholesterolemic treatment adjustment. Since he does not reach therapeutic goals with oral medication, he starts a treatment with fortnightly sessions of LDL-apheresis, which he keeps for 8 years. With the introduction and availability of PCSK9 inhibitors, a new treatment option is possible for this patient
