Jusvinza, an anti-inflammatory drug derived from the human heat-shock protein 60, for critically ill COVID-19 patients. An observational study.

This paper presents the results of an observational and retrospective study on the therapeutic effects of Jusvinza, an immunomodulatory peptide with anti-inflammatory properties for critically ill COVID-19 patients. This peptide induces regulatory mechanisms on the immune response in experimental systems and in patients with Rheumatoid Arthritis. Exploratory research in COVID-19 patients revealed that Jusvinza promotes clinical and radiological improvement. The aim of this study is to describe the clinical outcome and variations of several inflammatory biomarkers in a cohort of critically ill COVID-19 patients, divided into two groups during the observational research: one group received Jusvinza and the other did not. Research physicians extracted the patients´ data from their hospital's clinical records. The study analyzed 345 medical records, and 249 records from critically ill patients were included. The data covered the demographic characteristics, vital signs, ventilatory parameters and inflammatory biomarkers. Survival outcome was significantly higher in the group receiving Jusvinza (90.4%) compared to the group without Jusvinza (39.5%). Furthermore, in patients treated with Jusvinza there was a significant improvement in ventilatory parameters and a reduction in inflammation and coagulation biomarkers. Our findings show that Jusvinza could control the extent of inflammation in COVID-19 patients. This study indicates that Jusvinza is a helpful drug for the treatment of diseases characterized by hyperinflammation.

El tratamiento con Jusvinza disminuye la hiperinflamación y la hipercoagulación en pacientes críticos con la COVID-19

RESUMEN Introducción: La infección con el SARS-CoV-2 induce un estado protrombótico en los pacientes, atribuible a la combinación de la respuesta hiperinflamatoria y la hipoxia. En Cuba, se usa el fármaco Jusvinza, basado en un péptido inmunomodulador, para el tratamiento de los pacientes con la COVID-19, que presenten signos y síntomas de hiperinflamación. Objetivos: Describir la evolución clínica y las variaciones de biomarcadores asociados con la inflamación y la coagulación, en un grupo de pacientes críticos con la COVID-19, tratados con Jusvinza, en comparación con un grupo de pacientes que no recibieron tratamiento con este péptido. Métodos: Se incluyeron 40 pacientes críticos con la COVID-19; se dividieron en 2 grupos: 20 pacientes tratados con Jusvinza y 20 no fueron tratados con dicho péptido (grupo control). Las características demográficas, comorbilidades, signos vitales, parámetros respiratorios, biomarcadores de la inflamación y de la coagulación se obtuvieron a partir de las historias clínicas de cada paciente. Resultados: El tratamiento con Jusvinza indujo una mejoría clínica en los pacientes, asociada con la disminución de varios biomarcadores de la inflamación y la coagulación. La sobrevida de los pacientes tratados con Jusvinza fue significativamente superior a la sobrevida de los pacientes no tratados con este péptido. Conclusiones: Jusvinza es capaz de controlar la hiperinflamación y la hipercoagulación en pacientes críticos con la COVID-19.

ABSTRACT Introduction: Infection with SARS-CoV-2 induces a prothrombotic state in patients, by the combination of hyperinflammatory response and hypoxia. In Cuba, the drug called Jusvinza, based on an immunomodulatory peptide, is used for the treatment of patients with COVID-19, who present signs and symptoms of hyperinflammation. Objectives: To describe the clinical course and behavior of various biomarkers associated with the inflammation and coagulation, in a group of critically ill patients with COVID-19 treated with Jusvinza, compared to a group of patients who did not receive treatment with this peptide. Methods: 40 critically ill patients with COVID-19 were included. The patients were divided into 2 groups: 20 patients were treated with Jusvinza and 20 were not treated with this peptide (control group). Demographic characteristics, comorbidities, vital signs, respiratory parameters and inflammation and coagulation biomarkers were obtained from the medical records of each patient. Results: Treatment with Jusvinza induced a clinical improvement in the patients, associated with the decrease of several inflammation and coagulation biomarkers. Patients treated with Jusvinza had a significantly higher survival than patients not treated with this peptide. Conclusions: Jusvinza is able to control hyperinflammation and hypercoagulation in critical ill patients with COVID-19.
