Aprotinin treatment against SARS-CoV-2: A randomized phase III study to evaluate the safety and efficacy of a pan-protease inhibitor for moderate COVID-19.

BACKGROUND: SARS-CoV-2 virus requires host proteases to cleave its spike protein to bind to its ACE2 target through a two-step furin-mediated entry mechanism. Aprotinin is a broad-spectrum protease inhibitor that has been employed as antiviral drug for other human respiratory viruses. Also, it has important anti-inflammatory properties for inhibiting the innate immunity contact system. METHODS: This was a multicentre, double-blind, randomized trial performed in four Spanish hospitals comparing standard treatment versus standard treatment + aprotinin for patients with COVID-19 between 20 May 2020 and 20 October 2021. The primary efficacy outcomes were length of hospital stay and ICU admission. The secondary endpoints were each of the primary efficacy outcomes and a composite of oxygen therapy, analytical parameters and death. Safety outcomes included adverse reactions to treatment during a 30-day follow-up period. Treatment was given for 11 days or till discharge. RESULTS: With almost identical analytical profiles, significant differences were observed in treatment time, which was 2 days lower in the aprotinin group (p = .002), and length of hospital admission, which was 5 days shorter in the aprotinin group (p = .003). The incidence of discharge was 2.19 times higher (HR: 2.188 [1.182-4.047]) in the aprotinin group than in the placebo group (p = .013). In addition, the aprotinin-treated group required less oxygen therapy and had no adverse reactions or side effects. CONCLUSION: Inhaled aprotinin may improve standard treatment and clinical outcomes in hospitalized patients with COVID-19, resulting in a shorter treatment time and hospitalization compared with the placebo group. The administration of aprotinin was safe.

Diferencias epidemiológicas y de mortalidad entre hombres y mujeres con infección por VIH en la cohorte CoRIS entre los años 2004 y 2014 / Differences in epidemiology and mortality between men and women with HIV infection in the CoRIS cohort from 2004 to 2014

Objetivos: Analizar en la cohorte CoRIS las diferencias epidemiológicas y en la mortalidad entre mujeres y hombres que viven con VIH y su evolución en el tiempo. Métodos: Se compararon las variables de interés entre mujeres que viven con VIH y hombres que viven con VIH. Se realizó un análisis de tendencias usando la prueba de Mantel-Haenszel. Para estudiar la supervivencia se utilizaron las curvas de supervivencia de Kaplan Meier y un análisis de regresión de Cox. Resultados: Se incluyeron un total de 10.469 personas, de las cuales 1.742 (16,6%) eran mujeres. En el momento de inclusión en la cohorte las mujeres que viven con VIH con respecto a los hombres que viven con VIH tenían un mayor porcentaje de transmisiones por el uso de drogas intravenosas (UDI), coinfección por el virus de la hepatitisC (VHC), estadio de sida y origen extranjero. También presentaron una peor situación inmunovirológica y nivel de estudios. Estas diferencias se mantuvieron en el estudio de tendencias. En cuanto a la edad, las mujeres que se incluyeron en la cohorte fueron cada vez más mayores, y lo contrario sucedió con los hombres. En el análisis comparativo entre mujeres según su lugar de origen encontramos mujeres más mayores, con más transmisión por UDI y coinfección por VHC en el grupo de las mujeres que viven con VIH españolas; en cambio, la infección por sífilis fue más frecuente entre las nacidas fuera de España. No hubo grandes diferencias en relación con otras características, como el nivel de estudios o la situación de enfermedad. El sexo no fue un condicionante de supervivencia, y sí lo fueron factores que se asociaban más a las mujeres. Conclusiones: Las mujeres infectadas por el VIH se presentaron al diagnóstico con unas características epidemiológicas y asociadas a la infección por VIH que las hacen más vulnerables, y estas tendencias fueron acentuándose o no mejoraron durante los años de observación.(AU)

Introduction: This study sought to analyse differences in epidemiology and survival between women and men living with HIV in the CoRIS cohort and the course of their disease over a 10-year period. Methods: Variables of interest between women living with HIV and men living with HIV were compared. A trend analysis was performed using the Mantel-Haenszel test. Kaplan-Meier survival curves and a Cox regression analysis were used to study survival. Results: A total of 10,469 people were enrolled; of them, 1,742 (16.6%) were women. At the time of enrolment in the cohort, women living with HIV, compared to men living with HIV, had higher rates of transmission due to intravenous drug use (IDU), hepatitisC virus (HCV) coinfection, AIDS-stage disease and foreign origin. They also had a worse immunovirological status and a lower educational level. These differences were maintained in the trend study. Regarding age, the women included in the cohort were older whereas the men were younger. In the comparative analysis between women according to place of origin, we found that the group of Spanish women living with HIV featured older women with higher rates of IDU transmission and HCV coinfection, whereas the group of women living with HIV born outside of Spain featured women with higher rates of syphilis infection. There were no major differences in relation to other characteristics such as educational level or disease status. Although sex was not a determinant of survival, conditions more prevalent in women were determinants of survival. Conclusions: HIV-infected women presented at diagnosis with certain epidemiological and HIV-associated characteristics that made them more vulnerable. These trends became more marked or did not improve during the years of observation.(AU)

Differences in epidemiology and mortality between men and women with HIV infection in the CoRIS cohort from 2004 to 2014.

INTRODUCTION: This study sought to analyse differences in epidemiology and survival between women and men living with HIV (WLHIV and MLHIV) in the CoRIS cohort and the course of their disease over a 10-year period. METHODS: Variables of interest between WLHIV and MLHIV were compared. A trend analysis was performed using the Mantel-Haenszel test. Kaplan-Meier survival curves and a Cox regression analysis were used to study survival. RESULTS: A total of 10,469 people were enrolled; of them, 1,742 (16.6%) were women. At the time of enrolment in the cohort, WLHIV, compared to MLHIV, had higher rates of transmission due to intravenous drug use (IDU), hepatitis C virus (HCV) coinfection, AIDS-stage disease and foreign origin. They also had a worse immunovirological status and a lower educational level. These differences were maintained in the trend study. Regarding age, the women included in the cohort were older whereas the men were younger. In the comparative analysis between women according to place of origin, we found that the group of Spanish WLHIV featured older women with higher rates of IDU transmission and HCV coinfection, whereas the group of WLHIV born outside of Spain featured women with higher rates of syphilis infection. There were no major differences in relation to other characteristics such as educational level or disease status. Although sex was not a determinant of survival, conditions more prevalent in women were determinants of survival. CONCLUSIONS: HIV-infected women presented at diagnosis with certain epidemiological and HIV-associated characteristics that made them more vulnerable. These trends became more marked or did not improve during the years of observation.

Impact of interferon-free therapies in HIV/HCV co-infected patients on real clinical practice: results from a multicenter region-wide cohort study (2014-2018).

BACKGROUND: Here, we assess the efficacy and safety of direct antiviral agents (DAAs) in a real-world cohort of co-infected individuals, and evaluate the consistency between clinical practice and guideline recommendations. METHODS: Multicenter, prospective cohort study of HIV/HCV co-infected patients followed-up in nine sites in Spain. All patients with detectable HCV-RNA naive to second-generation DAAs were enrolled. The primary endpoint was the assessment of sustained virological response at week 12 (SVR12). We performed intention-to-treat (ITT), per-protocol (PP), and multivariable analyses to identify factors associated with therapeutic failure. We compared the DAAs we administered to available guideline recommendations. Schemes not perfectly adjusted to the recommendations were defined as sub-optimal. RESULTS: Overall, 316 patients (82.1% male) received a total of 330 treatments. Of these, 43.9% were cirrhotic and 40.6% were treatment-experienced. In the ITT and PP analyses, SVR12 was achieved in 90.9% [95% confidence interval (CI) 87.3-93.6] and 93.7% (95% CI 90.5-95.6), respectively. Only alcohol abuse [odds ratio (OR): 0.33; 95% CI 0.138-0.789, P = 0.013] and a higher basal bilirubin level (OR: 0.595; 95% CI 0.416-0.851, P = 0.004) were independently associated to therapeutic failure. A progressive decrease in the proportion of sub-optimal treatments was observed over time, from 75% in 2014 to 0% in 2018. Being treated with a sub-optimal regimen was not associated with failure. CONCLUSION: Despite numerous difficulties in treatment access and in adaptation to the changing guidelines, we detected no differences among the DAAs used, nor did we detect a lower efficacy when the chosen treatment was not optimal.
