Filter by:This study is a prospective cohort study aimed to clarify the continuous immune state changes of patients with COVID-19. Investigators include the patients admitted to the hospital within one week after the onset of COVID-19. 10ml of patients' blood was collected day 1, day 7, day 14 , and day 20 after the patients admitted to the hospital. The blood inflammatory factors, immune related molecules, and immune cells were detected to determine the changes of patients' immune status. The impact of immune status changes on prognosis and quality of life in later follow-up period was evaluated by various questionnaires and evaluation scales.
This study will evaluate the capacity of botanical extracts to modulate immune mechanisms compared to a placebo group in healthy volunteers.
This study was conducted to investigate the efficacy and safety of Black rice bran extract on immune enhancement.
The COVIDOUT study will prospectively investigate the serological immunity of outpatient cancer patients to evaluate the prevalence of previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and dependency of serological immunity on systemic (chemo)therapy after COVID19 disease as well as after vaccination.
The purpose of this study is to measure immunity to the flu vaccine over time in patients who had COVID-19. Adults who have been diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.
This study was conducted to investigate the efficacy and safety of ethanol extracts of Porphyra tenera(PTE10) on promotion of immunity
The purpose of this study is to determine whether BRAND'S® Essence of Chicken are effective in the promotion of resilience and resistance to stress-associated cognitive inhibition.
Background: It is well established that the presence of bacteria in the intestine has a profound influence on health. Probiotics, ("beneficial bacteria") have shown ameliorating effects on various infectious diseases. The influence of probiotics on several immune-mediated conditions has also been investigated, among them, atopic dermatitis ("Asthma of the skin"), and milk allergy. The precise mechanism of action of probiotics is not fully understood. Several animal and human studies have shown the probiotic bacteria to influence the immune system. The aim of the present study is to evaluate whether supplementing the diet with oral probiotics affects the immune response of children following routine vaccination against 4 common childhood viral diseases: Mumps, Measles, Rubella and Varicella. Objective(s) and Hypothesis(es): Hypothesis: Administration of probiotics will increase the amount of antibodies produced following vaccination for Measles, Mumps, Rubella and Varicella, by over 15%. Objectives: - To determine whether administration of probiotics during infancy influences antibody levels following the routine childhood vaccinations. - To determine whether administration of probiotics during infancy influences the rate of adverse effects following the routine childhood vaccinations. Potential Impact: Vaccines, alongside with the discovery of Penicillin, have been cited as the great public health successes of the 20th century. However, even in countries with maximal childhood immunization coverage, the protective effect is not optimal. For example, only 70% to 90% of children immunized against chickenpox are actually protected against the disease. If we succeed in raising these numbers, even by a single percent, it will have a huge impact on society.
