[Clinical characteristics of patients hospitalized with COVID-19 in Spain: Results from the SEMI-COVID-19 Registry]. / Características clínicas de los pacientes hospitalizados con COVID-19 en España: resultados del Registro SEMI-COVID-19.

BACKGROUND: Spain has been one of the countries most affected by the COVID-19 pandemic. OBJECTIVE: To create a registry of patients with COVID-19 hospitalized in Spain, in order to improve our knowledge of the clinical, diagnostic, therapeutic, and prognostic aspects of this disease. METHODS: A multicentre retrospective cohort study, including consecutive patients hospitalized with confirmed COVID-19 throughout Spain. Epidemiological and clinical data, additional tests at admission and at seven days, treatments administered, and progress at 30 days of hospitalization were collected from electronic medical records. RESULTS: Up to June 30th 2020, 15,111 patients from 150 hospitals were included. Their median age was 69.4 years (range: 18-102 years) and 57.2% were male. Prevalences of hypertension, dyslipidemia, and diabetes mellitus were 50.9%, 39.7%, and 19.4%, respectively. The most frequent symptoms were fever (84.2%) and cough (73.5%). High values of ferritin (73.5%), lactate dehydrogenase (73.9%), and D-dimer (63.8%), as well as lymphopenia (52.8%), were frequent. The most used antiviral drugs were hydroxychloroquine (85.6%) and lopinavir/ritonavir (61.4%); 33.1% developed respiratory distress. Overall mortality rate was 21.0%, with a marked increase with age (50-59 years: 4.7%, 60-69 years: 10.5%, 70-79 years: 26.9%, ≥ 80 years: 46.0%). CONCLUSIONS: The SEMI-COVID-19 Network provides data on the clinical characteristics of patients with COVID-19 hospitalized in Spain. Patients with COVID-19 hospitalized in Spain are mostly severe cases, as one in three patients developed respiratory distress and one in five patients died. These findings confirm a close relationship between advanced age and mortality.

[Description of hospital discharges in patients with systemic lupus erythematosus]. / Descripción de las altas hospitalarias en pacientes con lupus eritematoso sistémico.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease that mainly affects young women and whose mortality is increasing for this age group. OBJECTIVES: We used the national registry of Hospital discharges in Spain based on the study of the Minimum Basic Data Set (MBDS) to analyze hospital discharges of patients whose diagnosis included that of LES. MATERIAL AND METHODS: A cross-sectional, descriptive study was performed of all episodes coded as having LES using ICD-9-MC coding system of the patients hospitalized within the period 2005-2008. RESULTS: A total of 5,464 episodes were identified, 1,855 (33%) as main diagnosis and 3,609 (66%) as secondary diagnosis. Patients having LES the main diagnosis were younger (41.56 ± 17.55 vs 56.07 ± 19.01 years; P < .001), had fewer elective admittances (62.5 vs 84.8%; P<.001), lower comorbidity as measured by the Charlson's index (Charlson>2; 18 vs 35%; P<.001) and lower mortality (1.1 vs 5.4%; P < .001). CONCLUSIONS: Patients admitted to internal medicine departments in Spain with a diagnosis of LES accounts for 0.3% of the total. Two different groups of patients are identified. The first group was younger, had lower comorbidity and were in the early phases of diagnosis and/or treatment. The second group was more numerous, older, with a higher comorbidity, with admittances frequently related to infections or cardiovascular complications and higher mortality rate.

A risk score for prediction of recurrence in patients with unprovoked venous thromboembolism (DAMOVES).

BACKGROUND: In patients with unprovoked venous thromboembolism (VTE), the optimal duration of anticoagulation is anchored on estimating the risk of disease recurrence. We aimed to develop a simple risk assessment model that improves prediction of the recurrence risk. METHODS: In a prospective cohort study, 398 patients with a first unprovoked VTE were followed up for a median of 21.3months after discontinuation of anticoagulation. We excluded patients with a strong thrombophilic defect. Preselected clinical and laboratory variables were analyzed based on the independent confirmation of the impact on the recurrence risk, simplicity of assessment, and reproducibility. Multivariable Cox regression analysis was used to develop a recurrence score that was subsequently internally validated by bootstrap analysis. RESULTS: A total of 65 patients (16.3%) had recurrent VTE. In all patients, VTE recurred spontaneously. Male sex (HR=2.89 [95% CI 1.21-6.90] P=0.016), age (HR=1.0310 per additional decade [95% CI 1.01-1.07] P=0.011), obesity (HR=3.92 [95% CI 1.75-8.75] P=0.0001), varicose veins (HR=4.14 [95% CI 1.81-9.43] P=0.0001), abnormal D-dimer during anticoagulation (HR=13.66 [95% CI 4.74-39.37] P=0.0001), high factor VIII coagulant activity (HR=1.01 [95% CI 1.00-1.02] P=0.028) and heterozygous of factor V Leiden and/or Prothrombin G20210A mutation (HR=13.86 [95% CI 5.87-32.75] P=0.0001) were related to a higher recurrence risk. Using these variables, we developed a nomogram [hereafter referred to as DAMOVES score (D-dimer, Age, Mutation, Obesity, Varicose veins, Eight, Sex)] for prediction of recurrence in an individual patient. CONCLUSIONS: The DAMOVES score can be used to predict recurrence risk in patients with a first unprovoked VTE and may be useful to decide whether anticoagulant therapy should be continued indefinitely or stopped after an initial treatment period of at least 3months.

[Lymphocytic variant of the hypereosinophilic syndrome]. / Variante linfoide del síndrome hipereosinófilo.

OBJECTIVES: Hypereosinophilic syndromes (HSS) are a rare group of heterogeneous disorders characterized by prominent and persistent eosinophilia and organ dysfunction. Secondary causes of eosinophilia must be excluded. Recent advances in molecular biology and cytogenetics have permitted the characterization of different subsets of hypereosinophilic syndrome. We describe a patient with the lymphocytic variant. PATIENT: A 46-year old male Philippine patient presented skin lesions, fever, red eyes, enlarged lymph nodes and marked eosinophilia. RESULTS: Lymphocytic phenotyping by flow cytometry analysis was performed on peripheral blood and an aberrant population of T lymphocytes CD3-CD4+ producing interleukin 5 was found. TCR gene rearrangement using PCR amplification confirmed T cell clonality. CONCLUSIONS: The lymphocytic variant of the hypereosinophilic syndrome is a primitive lymphocytic disorder characterized by a non-malignant T cell population expansion producing eosinophilopoietic cytokines, with an indolent clinical course but that can transform into a peripheral T lymphoma. We report the first case of such a variant published in our country and review the characteristics of this variety.
