[Patients with COPD hospitalized due to COVID-19 in Spain: a comparison between the first and second wave]. / Pacientes con EPOC hospitalizados por COVID-19 en España: comparación entre la primera y la segunda ola.

Objective: This work aimed to compare the characteristics, progress, and prognosis of patients with COPD hospitalized due to COVID-19 in Spain in the first wave with those of the second wave. Material and methods: This is an observational study of patients hospitalized in Spain with a diagnosis of COPD included in the SEMI-COVID-19 registry. The medical history, symptoms, analytical and radiological results, treatment, and progress of patients with COPD hospitalized in the first wave (from March to June 2020) versus those hospitalized in the second wave (from July to December 2020) were compared. Factors associated with poor prognosis, defined as all-cause mortality and a composite endpoint that included mortality, high-flow oxygen therapy, mechanical ventilation, and ICU admission, were analyzed. Results: Of the 21,642 patients in the SEMI-COVID-19 Registry, 6.9% were diagnosed with COPD: 1,128 (6.8%) in WAVE1 and 374 (7.7%) in WAVE2 (p = 0.04). WAVE2 patients presented less dry cough, fever and dyspnea, hypoxemia (43% vs 36%, p < 0.05), and radiological condensation (46% vs 31%, p < 0.05) than WAVE1 patients. Mortality was lower in WAVE2 (35% vs 28.6%, p = 0.01). In the total sample, mortality and the composite outcome of poor prognosis were lower among patients who received inhalation therapy. Conclusions: Patients with COPD admitted to the hospital due to COVID-19 in the second wave had less respiratory failure and less radiological involvement as well as a better prognosis. These patients should receive bronchodilator treatment if there is no contraindication for it.

Covid-19 Vaccine Protection against Mortality in Patients with Oxygen: A Multicontinental Study

INTRODUCTION: The COVID-19 vaccines have effectiveness above 90% for avoiding hospitalization. However, 5% of vaccinated patients require hospitalization with a mortality ratio between 15% to 24%, similar to the one reported for unvaccinated hospitalized patients. These vaccinated patients belong to the most sensitive groups with a high comorbidity burden. The similarity in the mortality ratio between vaccinated and unvaccinated patients has been used to make claims against the vaccine's efficacy. A thoughtful analysis, taking into account the comorbidities of each group, on how vaccination protects patients with moderate or severe illness, is missing. METHOD(S): We perform a multi-continental retrospective cohort study in 111 hospitals in Spain and 37 in Argentina. We included hospitalized patients who received oxygen therapy older than 18 years with COVID-19. To assess the relation between COVID-19 vaccine status and death, we performed a logistic regression adjusting by confounders. Also, as a sensitivity analysis, we perform a propensityscore matching. Additionally, we studied the Population Attributable Risk (PAR). RESULT(S): Between January 2020 and May 2022, we included 21,479 patients, 717 (3 3%) were vaccinated. Hospitalized vaccinated patients with oxygen therapy had a higher proportion of comorbidities. The overall mortality in vaccinated patients was 20 9%, and 19 5% in unvaccinated patients. The crude Odds Ratio was 1 07 (IC95% 0 89-1 29;p=0 41), while the adjusted was 0 73 (IC95% 0 56-0 95;p=0 02) in the complete case analysis (6,352 patients) and 0 77 (CI 95% 0 54-0 97;p=0 02) in the complete dataset after multiple imputations. These observations were robust to the sensitivity analysis. The adjusted PAR reduction was 4 3% (95%CI 1%-5%). Therefore, as the death proportion in unvaccinated patients was 19 6% (95%CI 19%-20 1%), if they were vaccinated the expected death proportion would have been 15 3% (95%CI 12 9%-18%;p< 0 01). CONCLUSION(S): Even with the high protection of the COVID-19 vaccine, patients with a high burden of comorbidities will be hospitalized in future pandemic waves. In this study, we observed that the COVID-19 vaccines significantly reduce the probability of death even when lung inflammation has already been initiated, with moderate or severe COVID-19 disease.

Association of hypertension with all-cause mortalityamong hospitalized patients with COVID-19

Objective: It is unclear to which extent the higher mortality associated with hypertension in the coronavirus disease (COVID-19) is due to its increased prevalence among older patients or to speci fic mechanisms. The main objective of the study is to analyze whether HT represents an independent risk factor for death as a hard endpoint in patients hospitalized with SARS-CoV-2 in Spain Design and method: Cross-sectional, observational, retrospective multicenter study, analyzing 12226 patients who required hospital admission in 150 Spanish centers included in the nationwide SEMI-COVID-19 Network. We compared the clinical characteristics of survivors versus non-survivors Results: The mean age of the study population was 67.5 ± 16.1 years, 42.6% were women. Overall, 2630 (21.5%) subjects died. The most common comorbidity was hypertension (50.9%) followed by diabetes (19.1%), and atrial fibrillation (11.2%). Multivariate analysis showed that after adjusting for gender (males OR: 1.5, p = 0.0001), age tertiles (second and third tertiles, OR: 2.0 and 4.7, p = 0.0001), and Charlson Comorbidity Index scores (second and third tertiles OR: 4.7 and 8.1, p = 0.0001), hypertension was signi ficantly predictive of allcause mortality when this comorbidity was treated with angiotensin-converting enzyme inhibitors (ACEIs) (OR: 1.6, p = 0.002) or other than renin-angiotensinaldosterone blockers (OR: 1.3, p = 0.001) or angiotensin II receptor blockers (ARBs) (OR: 1.2, p = 0.035) Conclusions: The preexisting condition of hypertension had an independent prognostic value for all-cause mortality in patients with COVID-19 who required hospitalization. ARBs showed a lower risk of lethality in hypertensive patients than other antihypertensive drugs.

Clinical characteristics of patients hospitalized with COVID-19 in Spain: results from the SEMI-COVID-19 Registry

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. Design 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%). Conclusion 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. Resumen Antecedentes España ha sido uno de los países más afectados por la pandemia de COVID-19.
