RESUMEN
INTRODUCTION: Venous thromboembolism (VTE) may be the first sign of an undiagnosed cancer. The RIETE and SOME scores aim to identify patients with acute VTE at high risk of occult cancer. In the present study, we evaluated the performance of both scores. METHODS: The scores were evaluated in a retrospective cohort from two centers. The area under the receiver-operating characteristics curve (AUC) evaluated the discriminatory performance. RESULTS: The RIETE score was applied to 815 patients with provoked and unprovoked VTE, of whom 56 (6.9%) were diagnosed with cancer. Of the 203 patients classified as high-risk, 18 were diagnosed with cancer, representing 32.1% (18/56) of the total cancer diagnoses. In the group of 612 low-risk patients, 67.9% of the cancer cases were diagnosed (38/56). Sensitivity, specificity, negative and positive predictive values, and AUC were 32%, 76%, 94%, 9%, and 0.430 (95% confidence interval [CI], 0.38â0.47), respectively. The SOME score could be calculated in 418 patients with unprovoked VTE, of whom 33 (7.9%) were diagnosed with cancer. Of the 45 patients classified as high-risk, three were diagnosed with cancer, representing 9.1% (3/33) of the total cancer diagnoses. In the group of 373 low-risk patients, 90.9% of the cancer cases were diagnosed (30/33). Sensitivity, specificity, negative and positive predictive values, and AUC were 33%, 88%, 94%, 20%, and 0.351 (95% CI, 0.27â0.43), respectively. CONCLUSIONS: The performance of both scores was poor. Our results highlight the need to develop new models to identify high-risk patients who may benefit from an extensive cancer screening strategy.

BackgroundThe use of ACEI (Angiotensin-Converting Enzyme Inhibitor) and ARB (Angiotensin II Receptor Blocker) in COVID-19 remains controversial. Our main aim was to describe the effect of ACEI/ARB treatment during COVID-19 hospitalization on mortality and complications. MethodsRetrospective, observational, multicenter study, part of the SEMI-COVID-19 Registry, comparing patients with COVID-19 treated with ACEI/ARB during hospitalization to those not treated. The primary endpoint was incidence of the composite outcome of prognosis (IMV [Invasive Mechanical Ventilation], NIMV [Non-Invasive Mechanical Ventilation], ICU admission [Intensive Care Unit], and/or all-cause mortality). The secondary endpoint was incidence of MACE (Major Adverse Cardiovascular Events). We evaluated both outcomes in patients whose treatment with ACEI/ARB continued or was withdrawn during hospitalization. ResultsBetween February and June 2020, 11,205 patients were included, with mean age 67 years (SD=16.3) and 43.1% female; 2,162 patients received ACEI/ARB treatment. ACEI/ARB treatment showed a protective effect on all-cause mortality (p<.0001). In hypertensive patients it was also protective in terms of IMV, ICU admission, and the composite outcome of prognosis (p<.0001 for all). No differences were found in incidence of MACE. Patients previously treated with ACEI/ARB who continued treatment during hospitalization had a lower incidence of the composite outcome of prognosis than those whose treatment was withdrawn (RR 0.67, 95%CI 0.63-0.76). ARB had a more beneficial effect on survival than ACEI (HR 0.77, 95%CI 0.62-0.96). ConclusionACEI/ARB treatment during COVID-19 hospitalization had a protective effect on mortality. The benefits were greater in hypertensive patients, those who continued treatment during hospitalization, and those taking ARB. SummaryTreatment with ACEI/ARB during COVID-19 hospitalization showed a beneficial effect on mortality in the general population. The benefit was greater in hypertensive patients, in those who maintained treatment during hospitalization and those taking ARB.
RESUMEN
In patients receiving anticoagulant therapy for venous thromboembolism (VTE), the important issue of anemia influence on the risk of bleeding has not been consistently studied. We used the large registry data RIETE (Registro Informatizado Enfermedad Tromboembólica) to compare the rate of major bleeding in patients receiving anticoagulant therapy for VTE according to the presence or absence of anemia at baseline. Patients with or without cancer were separately studied. Until August 2016, 63492 patients had been enrolled. Of these, 21652 (34%) had anemia and 14312 (23%) had cancer. Anemia was found in 57% of the patients with cancer and in 28% without (odds ratio 3.46; 95% CI 3.33-3.60). During the course of anticoagulant therapy, 680 patients with cancer had a major bleeding event (gastrointestinal tract 43%, intracranial 14%, hematoma 12%). Cancer patients with anemia had a higher rate of major bleeding (rate ratio [RR]: 2.52; 95% CI 2.14-2.97) and fatal bleeding (RR 2.73; 95% CI 1.95-3.86) than those without anemia. During the course of anticoagulation, 1133 patients without cancer had major bleeding (gastrointestinal tract 32%, hematoma 24%, intracranial 21%). Patients with anemia had a higher rate of major bleeding (RR 2.84; 95% CI 2.52-2.39) and fatal bleeding (RR 2.76; 95% CI 2.07-3.67) than those without. On a multivariable analysis, anemia independently predicted the risk for major bleeding in patients with and without cancer (hazard ratios: 1.66; 95% CI 1.40-1.96 and 1.95; 95% CI 1.72-2.20, respectively). During anticoagulation for VTE, both cancer- and non-cancer anemic patients had a higher risk for major bleeding than those without anemia. In anemic patients (with or without cancer), the rate of major bleeding during the course of anticoagulant therapy exceeded the rate of VTE recurrences. In patients without anemia the rate of major bleeding was lower than the rate of VTE recurrences.
