ABSTRACT
Background: We compared the characteristics and clinical outcomes of hospitalized patients with COVID-19 with and without HIV infection (HIV-pos and HIV-neg) in Spain during the first wave of the pandemic. Methods: HIV-pos were identified by reviewing clinical records and laboratory registries of 10,922 patients in active-follow-up within the Spanish HIV Research Network (CoRIS) up to June 30, 2020. Each HIV-pos was matched with 5 HIV-neg of the same age and sex randomly selected from COVID-19@Spain, a multicenter cohort of 4,035 patients hospitalized with PCR confirmed COVID-19 in Spain (Clin Microbiol Infect 2020;26:1525-36). Data were collected with the ISARIC-WHO Core case report form (https://isaric.org/document/COVID-19-crf/). The COVID-19 SEIMC score (predictive of 30-day mortality), based on age, sex, dyspnea, O2 saturation, neutrophil-to-lymphocyte ratio, and estimated glomerular filtration rate, was calculated at admission in all patients (ESCMID Conference on Coronavirus Disease, 2020, Abstract#00513). Outcomes included the need for mechanical ventilation and all-cause in-hospital mortality. Results: Forty-five patients with PCR confirmed COVID-19 were identified in CoRIS, 21 of which were hospitalized. A total of 105 age/sex-matched controls were selected from COVID-19@Spain. The median age in both groups was 53 (Q1-Q3, 46-56) years, and 90.5% were men. In HIV-pos, 19.1% were IDUs, 95.2% were on ART, 94.4% had HIV-RNA < 50 copies/mL, and the median (Q1-Q3) CD4+ count was 595 (349-798) cells/mm3. No statistically significant differences were found between groups in number and type of comorbidities, presenting signs and symptoms, laboratory parameters, and radiology findings. The median (Q1-Q3) COVID-19 SEIMC score on admission was 4 (2-7) and 5 (3-7) in HIV-pos and HIV-neg, respectively;P=.890. Corticosteroids were administered to 33.3% and 27,4% HIV-pos and HIV-neg, respectively;P=.58. Remdesivir was administered to 0 and 2.9% of HIV-pos and HIV-neg, respectively;P=.426. During admission, 9.5% HIV-pos and 23.3% HIV-neg underwent mechanical ventilation;P=.158. In-hospital mortality was 9.5% in HIV-pos and 11.4% in HIV-neg;P=.800. Conclusion: Our findings suggest that well-controlled HIV infection does not modify the clinical presentation or worsen clinical outcomes in patients hospitalized with COVID-19. (Figure Presented).
ABSTRACT
BACKGROUND: There is an urgent need to reduce mortality of COVID-19. We examined if corticosteroids and tocilizumab reduce risk for death in patients with severe pneumonia caused by SARS-CoV-2. METHODS: A retrospective cohort study was performed in a single university hospital. All adult patients admitted with confirmed severe COVID-19 pneumonia from 9 March to 9 April 2020 were included. Severe pneumonia was defined as multi-lobar or bilateral pneumonia and a ratio of oxygen saturation by pulse oximetry to the fraction of inspired oxygen (SpFi)<315. All patients received antiviral and antibiotic treatment. From March 26, patients also received immunomodulatory treatment with corticosteroids (methylprednisolone 250 mg/day for 3 days), or tocilizumab or both. In-hospital mortality in the entire cohort and in a 1:1 matched cohort sub-analysis was evaluated. RESULTS: 255 patients were included, 118 received only antiviral and antibiotic treatment while 137, admitted after March 26, also received immunomodulators. In-hospital mortality of patients on immunomodulatory treatment was significantly lower than in those without [47/137(34.3%) vs. 69/118(58.5%), (p < .001)]. The risk of death was 0.44 (CI, 0.26-0.76) in patients receiving corticosteroids alone and 0.292 (CI, 0.18-0.47) in those treated with corticosteroids and tocilizumab. In the sub-analysis with 202 matched patients, the risk of death was 0.356 (CI 0.179-0.707) in patients receiving corticosteroids alone and 0.233 (0.124-0.436) in those treated with the combination. CONCLUSIONS: Combined treatment with corticosteroids and tocilizumab reduced mortality with about 25% in patients with severe COVID-19 pneumonia. Corticosteroids alone also resulted in lower in-hospital mortality rate compared to patients receiving only antiviral and antibiotic treatment. Corticosteroids alone or combined with tocilizumab may be considered in patients with severe COVID-19 pneumonia.
