Active clinical trials for "COVID-19"

The objective of this study is to provide remote mindfulness session(s) to help during the COVID-19 pandemic.

The present study will examine (1) the effectiveness of a combined brief advice and personalized chat-based support on COVID-19 related smoking messages and (2) explore the use of CBPR model to build capacity and to engage community partners in taking on this important public health issue for sustainability in the community. In addition, a process evaluation will be conducted to assess the effectiveness of the recruitment activity and how it is linked with the overall program outcomes.

The purpose of this study is to evaluate the effect of the probiotic Lactobacillus rhamnosus GG (LGG) and the effect of COVID-19 on the microbiome (the microorganisms that live in and on the human body) in exposed household contacts of COVID-19. This is a randomized, double-blind, placebo-controlled study, meaning subjects will be randomly assigned to receive LGG or a placebo (an inactive substance given in the same form as the active substance) and will not know which product they are receiving. Subjects will participate in the study for around 60 days. All subjects must refrain from taking any other probiotics while on study. All subjects must have access to e-mail and the internet to complete study questionnaires. Participation in this study entails taking LGG/placebo for 28 days, responding to questionnaires, and providing stool and nasal swab samples.

INTRODUCTION In critical situations, such as the current COVID 19 pandemic, themes of fear, uncertainty and stigmatization are common and constitute barriers to appropriate medical and mental health interventions. These challenges, when faced by those who live with a chronic disease, such as diabetes mellitus (DM), can negatively influence quality of life and adherence to treatment, compromising the control of the disease. OBJECTIVES The present study aims to investigate the effectiveness of a tele-intervention during the COVID-19 pandemic in improving glycemic control, lipid profile, blood pressure levels and parameters of medication adherence, mental well-being and sleep quality in patients with type 1 DM and type 2 DM. METHODS A randomized clinical trial will be carried out with patients with a previous diagnosis of type 1 DM and type 2 DM, who are registered at the Hospital de Clínicas de Porto Alegre (HCPA). Inclusion criteria will be age greater than or equal to 18 years, collection of HbA1c in the HCPA laboratory in January, February or March 2020 and availability to receive weekly phone calls. Patients will be randomized, stratified by type of diabetes, in two groups: G1: participants will receive a tele-intervention by a case manager weekly to discuss topics related to diabetes management and mental well-being during the social distancing period ; G2: participants will receive the usual care. The primary outcome assessed will be the variation in HbA1c levels comparatively between groups, with or without a tele-guided strategy, after four months of social distancing (or as long as the recommendation of social distancing measures remains). Secondary outcomes will include experiencing confirmation of COVID-19 infection, variation in lipid profile, blood pressure levels and variation in parameters of emotional distress related to diabetes, eating disorders, medication adherence, symptoms minor psychiatric disorders and altered sleep patterns, which will be evaluated with specific and validated scales. According to the sample calculation, 150 patients will be included in the study (92 with type 2 DM and 58 with type 1 DM). Analysis by intention to treat will be performed separately for patients with type 1 DM and with type 2 DM. SCHEDULE The proposed experiment will start immediately after approval of this project by the research ethics committee. The duration of the proposed intervention is 4 months (or as long as the recommendation of social distancing measures remains. This means that the study may be completed before or after that period, based on national recommendations for social distancing in Brazil), with a data analysis plan and publication of the results until September 2020.

The mechanism of peripheral blood lymphocyte decline in COVID-19 patients is not yet clear. However, one theory demonstrated that in the whole progression of COVID-19, the extensive activation of poly-ADP-ribose polymerase (PARP) may reduce the cellular NAD+ and dampen the adaptive immune system. So investigators presume that replenishing the NAD+ using nicotinamide as the precursor may improve the lymphocyte counts and boost the adaptive immune system. As a result, the study using nicotinamide as a kind of supportive therapy provide further evidence of their efficiency and safety in treating lymphopenia in patients with COVID-19.

This study aims to gain more insight in the immunological characteristics and immune response on a local level (the nose) and systemic level (the blood) of healthy people vaccinated with the current available COVID-19 messenger ribonucleic acid (mRNA; BNT162b2) and viral vector based (ChAdOx1) vaccines.

The aim of the study is to provide clinical decision support to healthcare professionals using a wearable for non-invasive multimodal monitoring, allowing early detection of disease progression to severe forms, as well as the detection of significant clinical events. For the development of the study, 500 individuals with COVID-19 in home confinement will be randomly assigned to form part of the control group, which will be followed conventionally by Primary Care Professionals, or to the experimental group, which will also be provided with the wearable device for non-invasive multimodal monitoring linked to an App for transfering data. Furthermore, the patient will be able to interact with the application on three times daily by indicating the symptoms contemplated and answering the decision clinical questions. In this way, alarms can be generated in the presence of symptoms or significant alterations in the parameters monitored by the device, which the health professionals of the Primary Care teams included in the study will evaluate at the appropriate time, taking the best decision in each case.

This study will explore the contribution of CBD oral drops in persons experiencing symptoms of Post Acute COVID Syndrome or "PACS".

A Randomized, Double-Blind, Placebo-Controlled, Dose-Escalating Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacodynamics, Pharmacokinetics, and Immunogenicity of HLX71 in Healthy Adult Subjects

SARS-CoV-2 infection is a condition characterized by excessive leukocyte infiltration, massive release of chemokines, proteases and cytokines, the so-called "cytokine storm", which promote the inflammatory process and contribute to exacerbation of COVID-19 symptomatology. Because of the abnormal release of pro-inflammatory cytokines by non-neuronal cells of the immune system, such as the mast cells in periphery, and microglia at central level, the body activates a defensive neuroinflammatory process that, if not controlled, can become pathological. Therefore it's important to intervene early on neuroinflammation, in order to limit the progression of the disease. A possible intervention is represented by Palmitoylethanolamide (PEA), an endogenous molecule of the N-acylethanolamine family synthesized "on demand" in response to "stress factors" to restore tissue homeostasis, able to control mast cells and microglia uncontrolled activation. Experimental evidence in vitro and in vivo demonstrated the anti-inflammatory and neuroprotective effect of micronized and ultra-micronized PEA (mPEA and umPEA), confirmed in various clinical investigations conducted in patients with different pathological conditions. The aim of this study is to investigate the efficacy of a compound containing mPEA + umPEA on peripheral inflammatory markers, neuroinflammation, and others clinical parameters in intensive care patients with COVID-19 interstitial pneumonia.
