ABSTRACT
The chemokine receptor CCR5 has been implicated in COVID-19. CCR5 and its ligands are overexpressed in patients. The pharmacological targeting of CCR5 would improve the COVID-19 severity. We sought to investigate the role of the CCR5-Δ32 variant (rs333) in COVID-19. The CCR5-Δ32 was genotyped in 801 patients (353 in the intensive care unit, ICU) and 660 healthy controls, and the deletion was significantly less frequent in hospitalysed COVID-19 than in healthy controls (p = 0.01, OR = 0.66, 95%CI = 0.49-0.88). Of note, we did not find homozygotes among the patients, compared to 1% of the controls. The CCR5 transcript was measured in leukocytes from 85 patients and 40 controls. We found a significantly higher expression of the CCR5 transcript among the patients, with significant difference when comparing the non-deletion carriers (controls = 35; patients = 81; p = 0.01). ICU-patients showed non-significantly higher expression than no-ICU cases. Our study points to CCR5 as a genetic marker for COVID-19. The pharmacological targeting of CCR5 should be a promising treatment for COVID-19.

We had the opportunity to know a judicial decision in relation to a nonagenarian COVID-19 patient, which is clarifying regarding the complex issue of involuntary admission and involuntary treatment of the elderly. The judge authorized the involuntary admission but denied the possibility of imposing medical treatment against the will of the patient. This situation invites us to review the different types of involuntary admission that our legal system provides and how involuntary medical treatment is regulated according to its purpose and the patient's ability to decide. In the field of public health, the determining element to be able to impose any sanitary measure against the will of the patient is the risk to the health of the population. In the case presented, the judge rejects the possibility of authorizing medical treatment for not contributing anything from the point of view of public health. However, it does authorize involuntary admission as it is essential to guarantee isolation.

OBJECTIVE: The SARS-CoV-2 pandemic conditions high mortality rates in hospitalized elderly. Currently, a few studies include octogenarian patients and none of them analyze the impact of functional status on this health outcome. Our objective is to describe the characteristics of patients older than 80 years hospitalized for coronavirus disease 2019 (COVID-19), to determine the mortality rate and to identify associated factors. MATERIAL AND METHODS: Prospective observational study carried out on patients over 80 years admitted for COVID-19 in a Geriatrics Service. Sociodemographic, clinical, functional, mental, analytical, radiological, therapeutic and healthcare variables were collected. The factors associated with in-hospital lethality were analyzed by bivariate analysis. RESULTS: 58 cases with laboratory-confirmed COVID-19 were included, mean age 88.3 ± 5.4 years, 69% women, 65.5% moderate-severe cognitive impairment and previous Barthel index 40.66 ± 36. The main symptoms were fever (60,3%), dyspnea (53.4%) and deterioration of functional condition (50%). The most frequent comorbidities were cardiovascular disease (75.9%), hypertension (HT) (74.1%) and chronic kidney disease (CKD) (50%). A mortality rate of 41,4% was detected and the associated factors were: severe functional dependence (OR = 3.8 [1.2-12.2]), moderate-severe cognitive impairment (OR = 4.9 [1-25.4]) and CKD (OR = 3.2 [1.1-9.7]). CONCLUSION: High mortality rates are observed in older patients hospitalized for COVID-19, with a higher risk of dying in those with severe functional dependence or cognitive impairment. These findings reinforce the value of Geriatric Assessment to develop strategies to adapt diagnostic and therapeutic decision-making and to optimize care for elderly patients in the event of a new epidemic outbreak.
