Incidence of pulmonary embolism in non-critically ill COVID-19 patients. Predicting factors for a challenging diagnosis.

Recent studies suggest that thrombotic complications are a common phenomenon in the novel SARS-CoV-2 infection. The main objective of our study is to assess cumulative incidence of pulmonary embolism (PE) in non critically ill COVID-19 patients and to identify its predicting factors associated to the diagnosis of pulmonary embolism. We retrospectevely reviewed 452 electronic medical records of patients admitted to Internal Medicine Department of a secondary hospital in Madrid during Covid 19 pandemic outbreak. We included 91 patients who underwent a multidetector Computed Tomography pulmonary angiography(CTPA) during conventional hospitalization. The cumulative incidence of PE was assessed ant the clinical, analytical and radiological characteristics were compared between patients with and without PE. PE incidence was 6.4% (29/452 patients). Most patients with a confirmed diagnosed with PE recieved low molecular weight heparin (LMWH): 79.3% (23/29). D-dimer peak was significatly elevated in PE vs non PE patients (14,480 vs 7230 mcg/dL, p = 0.03). In multivariate analysis of patients who underwent a CTPA we found that plasma D-dimer peak was an independen predictor of PE with a best cut off point of > 5000 µg/dl (OR 3.77; IC95% (1.18-12.16), p = 0.03). We found ninefold increased risk of PE patients not suffering from dyslipidemia (OR 9.06; IC95% (1.88-43.60). Predictive value of AUC for ROC is 75.5%. We found a high incidence of PE in non critically ill hospitalized COVID 19 patients despite standard thromboprophylaxis. An increase in D-dimer levels is an independent predictor for PE, with a best cut-off point of > 5000 µg/ dl.

[Relationship between pulse pressure and clinical cardiovascular damage in elderly subjects of EPICARDIAN study]. / Relación entre presión de pulso y antecedente de enfermedad cardiovascular en ancianos de dos poblaciones pertenecientes al estudio EPICARDIAN.

INTRODUCTION: Arterial hypertension and aging are the main cardiovascular risk factors (CVRF) in the elderly population. Aging is associated with an increase in systolic blood pressure (SBP) levels and a decrease of diastolic blood pressure (DBP), due to increased large artery stiffness. Several epidemiological studies have demonstrated that pulse pressure (PP) is an independent risk factor, better than SBP, for overall, cardiovascular mortality, coronary heart disease and cerebrovascular, particularly in the elderly. OBJECTIVES: To determine the association of PP with clinical cardiovascular damage, in a population-based sample of Spanish elders subjects. To quantify the association between PP and the background of clinical cardiovascular damage. To determine which PP, SBP, DBP or mean arterial pressure (MAP) are better associated to the history of clinical cardiovascular damage. PATIENTS AND METHODS: The sample analyzed included individuals from the EPICARDIAN study in the areas of Lista district (Madrid) and Arévalo (Avila). The following CVRF of age, gender, hypertension, diabetes, dyslipidemia, obesity, abdominal obesity and smoking were considered. Clinical cardiovascular damage is defined as the personal background of stroke, myocardial infarction, angina pectoris and/or intermittent claudication. RESULTS: The sample included 2665 individuals, 56% women, mean age: 74 year-old; 74.3% were hypertensive, 55.6% had central obesity and 31.9% hypercholesterolemia. In the multivariate analysis, the PP was the BP parameter associated most to stroke, angina pectoris and intermittent claudication: OR, 1.015, (95% CI: 1.001-1.030), 1.029 (95% CI: 1.006-1.052) and 1.012 (95% CI: 1.002-1.023), respectively. CONCLUSIONS: In the elderly population studied, an elevated PP is the component of arterial pressure with the greatest association to the background of cardiovascular damage.

[Leprosy simulating other diseases]. / Lepra simulando otras enfermedades.

The low current prevalence of leprosy in Spain together with the diversity of its clinical expression make the detection of this disease difficult. Three native and three imported cases are here reported. Different specialists mistook this disease for other entities: familial polyneuropathy, autoimmune disease, tuberculosis, cutaneous mycosis, and cutaneous sarcoidosis. Lepra is a very polymorphic disease and its diagnosis is based on finding cutaneous hypoesthesic lesions, neural thickening and presence of acid-fast bacilli (in cutaneous specimens or nasal exudates).
