Viral respiratory infections are common infectious complications after kidney transplantation, especially in the pediatric age group, and immunosuppressed patients may develop more severe disease. Immunosuppressive medications alter the patient's immune response by acting on humoral, cellular immunity and neutrophil function, increasing the risk of serious viral infections. Little is known about how these patients respond to infection by the new coronavirus (SARS-CoV-2). Experience with SARS caused by the Influenza H1N1 virus suggests that the severity of the disease depends on pre-existing comorbidities and the individual immune response. In more severe cases, an imbalance between the inflammatory system and the immune system is observed, determining direct consequences when pro and anti-inflammatory cytokines reach the systemic circulation in an exacerbated and unbalanced manner. Such fact can generate "cytokine storm syndrome", resulting in multiple organ dysfunction syndrome. March 2020 reports from Papa Giovanni XXIII Hospital in Bergamo, Italy - one of the largest pediatric liver transplant centers - showed that the number of transplant patients infected with Coronavirus disease 2019 (COVID- 19) increased progressively. However, they did not see greater severity and complications in this population. Immunosuppression could act as a protective factor. The present study aims to describe the prevalence of viral infection by SARS-CoV-2 in a sample of immunosuppressed children, from three groups: kidney transplants, liver transplants and oncohematological. The investigators will also look for the epidemiological profile and clinical evolution of these patients, enabling a better understanding of the COVID-19 in this special population. The investigators' hypothesis is that infection with the new coronavirus may be asymptomatic in a large number of children and that immunosuppression, observed in liver and kidney transplant patients and also seen in cancer patients, may act as protection for severe forms of COVID-19. After obtaining written informed consent from the family, the investigators will include patients from 0-18 years of age, on regular outpatient follow-up, symptomatic or not, and will check for the presence of IgM/IgG antibodies against the SARS-CoV-2. For those symptomatic or with a positive IgM result, material (oro/nasopharyngeal swabs) for RT-PCR trial for the new coronavirus will be collected. Demographic and clinical variables will be registered. The outcomes are: Serology for COVID-19 result; PCR for COVID-19 result; presence of symptoms of COVID-19; proportion of patients with viral shedding on days 3,7,14,21 and 30 after diagnosis; need for hospital admission; need for Intensive care admission; death.
Convalescent plasma is a way to provide passive immunity to a person exposed to an infectious agent. It has been used as a therapeutic tool for emerging viral infections without specific treatment and with high morbidity and mortality, such as Influenza H1N1, H5N1, H7N9, Ebola, MERS, SARS-CoV1, and even SARS-Cov2, with satisfactory results regarding evolution clinic of patients treated and without significant adverse events reported. One of its main advantages of convalescent plasma is to generate a rapid immune response (even faster than a vaccine), against a pathogen that circulates in a specific geographic area, probably common for both donor and recipient.
The purpose of this study is to demonstrate the superiority of Polyoxidonium®, lyophilizate for solution for injections and topical application, 6 mg over placebo in hospitalized patients with coronavirus disease (COVID-19). This is a multicentre prospective, randomized, double-blind, placebo-controlled, parallel-group phase IIb\IIIa clinical trial.
The overall purpose of this project is to better understand the incidence, risk factors, etiology, clinical manifestations and outcome of tCOVID19 in solid organ transplant recipients. The results obtained will allow us to gain insight on the need of antiviral treatment, on the strategy for complications surveillance, on how to adjust the immunosuppressant therapy and on the level of care in which each patient should be treated. In order to attain the objectives previously described we will develop a multicenter prospective study of consecutive cases of COVID-19 among solid organ transplant recipients.
