Abstract
The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The infection is caused when Spike-protein (S-protein) present on the surface of SARS-CoV-2 interacts with human cell surface receptor, Angiotensin-converting enzyme 2 (ACE2). This binding facilitates SARS-CoV-2 genome entry into the human cells, which in turn causes infection. Since the beginning of the pandemic, many different therapies have been developed to combat COVID-19, including treatment and prevention. This review is focused on the currently adapted and certain other potential therapies for COVID-19 treatment, which include drug repurposing, vaccines and drug-free therapies. The efficacy of various treatment options is constantly being tested through clinical trials and in vivo studies before they are made medically available to the public.

Res Pract Thromb Haemost 2023; 7:100068. [PMID: 36777286 PMCID: PMC9901222 DOI: 10.1016/j.rpth.2023.100068] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/23/2022] [Accepted: 01/08/2023] [Indexed: 02/08/2023] Open
Abstract
Background Although early evidence concluded a lack of clinical benefit of convalescent plasma therapy (CPT) in COVID-19 management, recent trials have demonstrated the therapeutic potential of CPT in ambulatory care. CPT may also potentiate thromboembolic events, given the presence of coagulation factors and the prothrombotic state of COVID-19. Objectives The present study aimed to assess and compare the clinical efficacy and the risk of venous thromboembolism (VTE)/arterial thromboembolism (ATE) of CPT in ambulatory versus hospitalized patients with COVID-19. Methods MEDLINE, Embase, and Cochrane CENTRAL were searched from December 2019 to December 2022 for randomized controlled trials that investigated the use of CPT against placebo or standard of care in adult patients with COVID-19. The primary outcome was nonmortality disease progression. Secondary outcomes include VTE, ATE, 28-day mortality, clinical improvement, length of hospitalization, sepsis/fever, and major adverse cardiovascular events. Results Twenty randomized controlled trials, with 21,340 patients, were included. CPT significantly reduced nonmortality disease progression in ambulatory patients (odds ratio [OR], 0.72; 95% CI, 0.56-0.92; P = .009) but not in hospitalized patients (OR, 1.03; 95% CI, 0.94-1.12; P = .58). The risk of VTE and ATE did not differ between the CPT and the control group (OR, 1.16; 95% CI, 0.82-1.66; P = .40; and OR, 1.01; 95% CI, 0.37-2.79; P = .98, respectively). No conclusive differences between CPT and control groups were noted in 28-day mortality, clinical improvement, length of hospitalization, risk of sepsis/fever, and major adverse cardiovascular events. Conclusion In conclusion, treatment of COVID-19 with CPT prevents the progression of COVID-19 in the ambulatory care. It is not associated with an increased risk of VTE, ATE, or other adverse events.

The Successful Recovery of a Critically Ill COVID-19 Patient, Following the Combination of Therapeutic Plasma Exchange and Convalescent Plasma Transfusion: A Case Report. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58081088. [PMID: 36013555 PMCID: PMC9416755 DOI: 10.3390/medicina58081088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/05/2022] [Accepted: 08/09/2022] [Indexed: 11/16/2022]
Abstract
With an intricate symptom pattern involving a dysregulated host response to infection, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause severe inflammation and cytokine storms, acute respiratory distress syndrome, coagulopathy, multi-organ failure, and finally death. The uniqueness of this case report lies in the nature of the therapeutic intervention performed. While numerous studies are available on both the use of therapeutic plasma exchange in coronavirus disease 2019 (COVID-19) patients and convalescent plasma transfusion as separate treatment methods, there is very little information regarding the combination of these procedures. We present the case of a 52-year-old male, unvaccinated for COVID-19, who tested positive on reverse transcriptase polymerase chain reaction for SARS-CoV-2 for the first time and presented in the emergency room with fever, chills, severe cough, tachypnea, tachycardia, and dyspnea that started two days before presentation. Upon rapid assessment, the patient showed signs of acute respiratory failure, so it was decided to transfer the patient to the intensive care unit, COVID-19 ward, after preliminary radiological examination. For the next 24 days, the patient was stationed in the intensive care unit, where he was closely monitored and treated. Invasive mechanical ventilation was required following the initial worsening of his respiratory status. We performed therapeutic plasma exchange on the first day of his stay in the intensive care unit, and immediately after the procedure, the patient was transfused with 500 mL of convalescent plasma from healthy donors. The patient's condition improved over the next few days, which led to the cessation of mechanical ventilation and, after treating the superinfection, the patient was discharged home, making a full recovery. The early initiation of therapeutic plasma exchange followed by transfusion of convalescent plasma in severe and critical forms of COVID-19 may reduce the risk of the progression of the disease and ultimately reduce the risk of negative outcomes in a selected group of patients.

Therapeutic plasma exchange followed by convalescent plasma transfusion in severe and critically ill COVID-19 patients: A single centre non-randomized controlled trial. Exp Ther Med 2021; 23:76.

Abstract
Therapeutic plasma exchange (TPE) has been proposed as a rescue therapy in critically ill COVID-19 patients. The aim of the present study was to determine whether combining TPE with convalescent plasma (CVP) transfusion early in the intensive care unit (ICU) stay improves survival among this heterogeneous population. The primary endpoint was survival at 30 days. Secondary endpoints included assessing the evolution of biomarkers, such as the partial pressure of arterial oxygen to fractional inspired oxygen ratio, and C reactive protein (CRP), lactate dehydrogenase (LDH) and ferritin levels at the 7-day follow-up. This single centre, prospective, non-randomized controlled trial was conducted in an 8-bed COVID-19 ICU and included patients with severe COVID-19 pneumonia requiring intensive care treatment. A total of 19 patients were treated by performing TPE followed by CVP transfusion, in addition to standard treatment, while for another 19 patients, only standard treatment according to hospital protocols was used. TPE was initiated during the first 24 h after ICU admission, followed immediately by transfusion of CVP. Survival at 30 days was 47.37% in the TPE CVP group and 26.32% in the control group (P=0.002). Patients in the TPE CVP group also showed better oxygenation and a reduction in inflammation, with decreased CRP, LDH and ferritin levels compared with those in the control group. Overall, the study indicated that early initiation of TPE followed by CVP transfusion may be a valid rescue therapy in severe and critically ill COVID-19 patients, with a statistically significant survival benefit, improved oxygenation and a reduction in inflammatory markers. The trial was registered in the ClinicalTrials.gov database (trial registration number: NCT04973488) on July 22, 2021 (retrospectively registered).

Abstract
Novel therapies for the treatment of COVID-19 are continuing to emerge as the SARS-Cov-2 pandemic progresses. PCR remains the standard benchmark for initial diagnosis of COVID-19 infection, while advances in immunological profiling are guiding clinical treatment. The SARS-Cov-2 virus has undergone multiple mutations since its emergence in 2019, resulting in changes in virulence that have impacted on disease severity globally. The emergence of more virulent variants of SARS-Cov-2 remains challenging for effective disease control during this pandemic. Major variants identified to date include B.1.1.7, B.1.351; P.1; B.1.617.2; B.1.427; P.2; P.3; B.1.525; and C.37. Globally, large unvaccinated populations increase the risk of more and more variants arising. With successive waves of COVID-19 emerging, strategies that mitigate against community transmission need to be implemented, including increased vaccination coverage. For treatment, convalescent plasma therapy, successfully deployed during recent Ebola outbreaks and for H1N1 influenza, can increase survival rates and improve host responses to viral challenge. Convalescent plasma is rich with cytokines (IL-1β, IL-2, IL-6, IL-17, and IL-8), CCL2, and TNFα, neutralizing antibodies, and clotting factors essential for the management of SARS-CoV-2 infection. Clinical trials can inform and guide treatment policy, leading to mainstream adoption of convalescent therapy. This review examines the limited number of clinical trials published, to date that have deployed this therapy and explores clinical trials in progress for the treatment of COVID-19.

Abstract
The DisCoVeRy clinical trial aimed at the evaluation of four treatments for patients suffering from severe to critical COVID-19: Hydroxychloroquine, eventually associated with azithromycin; the combination lopinavir/ritonavir; the combination with the addition of interferon β-1a; remdesivir. The trial was discontinued due to the lack of positive results. Meanwhile, many other potential options have been considered either to target the virus itself, the interactions with the host cells, or the cytokine storm frequently observed during the infection. Several of those options are briefly reviewed. They include vaccines, small molecules, antibodies, and stem cells.

Abstract
Vaccines and therapeutics targeting viral surface glycoproteins are a major component of disease prevention for respiratory viral diseases. Over the years, vaccines have proven to be the most successful intervention for preventing disease. Technological advances in vaccine platforms that focus on viral surface glycoproteins have provided solutions for current and emerging pathogens like SARS-CoV-2, and our understanding of the structural basis for antibody neutralization is guiding the selection of other vaccine targets for respiratory viruses like RSV. This review discusses the role of viral surface glycoproteins in disease intervention approaches.
