Filter by:Trigeminal neuralgia is a type of neuropathic pain that brings great physical and psychological pressure to patients. Chronic pain can cause changes in the composition of central and peripheral body fluids, and these changes may be useful for the prediction and treatment of pain. In this study, the whole blood of patients with trigeminal neuralgia and non-chronic pain was collected, and transcriptome sequencing (RNA-seq) was performed to determine the peripheral transcriptome changes of trigeminal neuralgia (TN) patients. And compare the expression of neuropeptide Y (NPY) in plasma and cerebrospinal fluid of TN and non-chronic pain patients.
One investigational treatment being explored for COVID-19 is the use of convalescent plasma collected from individuals who have recovered from COVID-19 (Refs. 1-4). Convalescent plasma that contains antibodies to severe acute respiratory syndrome coronavirus 2 or SARSCoV-2 (the virus that causes COVID-19) is being studied for administration to patients with COVID-19. Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including the 2003 SARS-CoV-1 epidemic, the 2009-2010 H1N1 influenza virus pandemic, and the 2012 MERS-CoV epidemic (Refs. 5-7). Although promising, convalescent plasma has not yet been shown to be safe and effective as a treatment for COVID-19. Therefore, it is important to study the safety and efficacy of COVID19 convalescent plasma in clinical trials. This guidance provides recommendations to health care providers and investigators on the administration and study of investigational convalescent plasma collected from individuals who have recovered from COVID-19 (COVID-19 convalescent plasma) during the public health emergency. This guidance also provides recommendations to blood establishments on the collection of COVID-19 convalescent plasma..
The present study will try to respond first in an initial phase, what is the minimum effective dose necessary of convalescent plasma for getting better in severly ill (not intubated) or very severely ill (intubated) patients. Once the dose will be determined by each type of patient group (severely ill vs. very severely ill) has been determined, phase 2 of the study will begin, where the safety and efficacy of the use of plasma will be evaluated based on clinical, imaging and laboratory criteria. So, our hypotheses are: 1. Is there a minimum effective dose to treat seriously ill patients with convalescent plasma with COVID-19? 2. the plasma dose with the minimum effective effect will improve the clinical, laboratory and clearance conditions of the presence of the virus in the severely ill patient?
