NCT ID: NCT05778383 Completed - Clinical trials for Sars-CoV-2 Infection

Zinc Supplementation Impact in Acute COVID-19 Clinical Outcomes

MARZINC
Start date: May 1, 2021
Phase: Phase 4
Study type: Interventional

Infections with SARS-CoV-2 result in a systemic disease with a variety of outcomes, from no symptoms to severe and diverse pathologies. Therefore, it is important to identify risk factors determining COVID-19 severity, especially if those factors might be adjusted, allowing early and effective therapeutic interventions. Zinc is a trace element essential for human health. Zinc deficiency is common in old adults, vegetarians and patients with chronic inflammatory diseases. This condition causes immune dysfunction leading to increased risk of inflammatory and infectious diseases, including acquired immune deficiency syndrome, measles, malaria, tuberculosis, and pneumonia. Besides, zinc has a direct antiviral activity against specific viruses like rhinovirus, HCV, herpes simplex virus. In this scenario, it has been shown that zinc supplementation has benefits on the recurrence and persistence of acute and chronic viral infections like common cold or HCV, HBV. Moreover, our team has recently done an observational study with 249 COVID-19 patients that showed how COVID-19 patients with lower plasma zinc content had worse prognosis, increased time of hospitalization and mortality. Therefore, the main aim of the project is to explore the therapeutic benefit of zinc supplementation for COVID-19 patients and to determine the cellular and molecular basis of the effect of Zn levels on SARS CoV-2 infections. For that purpose the investigators will run a clinical trial supplementing with zinc COVID-19 patients. Moreover, the investigators will carry out experiments to understand the association between zinc nutritional status and SARS-Cov-2 infection progression in cellular and animal models. Given the current knowledge about zinc supplementation toxicity and dosage, the investigators expect that recommendations derived from this study will be rapidly applied by physicians and public health decision makers. The results of these studies will be used as a guideline to administer zinc supplements in COVID-19 patients in order to reduce disease severity and mortality. Moreover, the experiments will clarify whether zinc supplementation as a prophylaxis strategy is useful to protect the population at risk of zinc deficiency, more than 20% worldwide. Finally, considering the new knowledge that this project will generate about the role of zinc in immune responses and viral expansion, the investigators expect that our results will help researchers and physicians to design novel strategies to boost specific immune cell subpopulations against SARS-CoV2 infection. Thus, this knowledge could be used long-term for designing medicines against SARS-CoV-2 and other viral infections.

Zinc Intervention in Elderly for Prevention of Pneumonia

ZIPP
Start date: May 3, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

Pneumonia is a major public health problem for the elderly and is one of the leading causes of hospitalization and death for this population, particularly for elderly nursing home residents. This planning grants seeks to establish a safe and effective dose of zinc supplementation with the goal to conduct a larger randomized clinical trial to study the effect of zinc supplementation in nursing home elderly with low serum zinc levels on the risk, antibiotic use, and duration of sick days with pneumonia. This project has significant potential to positively impact the health and quality of life in the elderly and to reduce the economic costs associated with their care.

NCT ID: NCT05236374 Completed - Inflammation Clinical Trials

Effects of Daily Beef Intake, as a Component of a Heart-Healthy Diet on Cellular Zinc

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

The objective of the current study is to test the overarching hypothesis that the beef nutritive matrix is uniquely suited to direct dietary zinc to cellular compartments for improved metabolic function, leading to a greater effect on health outcomes. Specifically, whether beef, as a component of a healthy meal, will promote the absorption of zinc into cells, where the zinc will have greater effects on zinc-dependent metabolic processes supporting cardiovascular health. To maximize the observability of these beef-related effects, individuals who are 55- to 70-year-old who generally have a higher risk of zinc deficiency and cardiovascular disease will be enrolled.

NCT ID: NCT05178407 Active, not recruiting - Anemia Clinical Trials

Effect of Household Use of Multiple Micronutrient-fortified Bouillon on Micronutrient Status Among Women and Children in Two Districts in the Northern Region of Ghana

Start date: January 16, 2023
Phase: N/A
Study type: Interventional

Background: Micronutrient (MN) deficiencies are severe and widespread in West Africa, particularly among young children and women of reproductive age. Bouillon is a promising food fortification vehicle because the product is centrally processed on large scale, consumed by most households in West African countries (even rural, poor households), and consumed by most members of the household in relatively constant amounts. However, several important research questions remain regarding whether the use of fortified bouillon would be feasible and effective for preventing or reducing micronutrient deficiencies in communities where such deficiencies are common. Specifically, no studies have assessed the impacts of multiple micronutrient-fortified bouillon on micronutrient status. The West Africa Condiment Micronutrient Innovation Trial (CoMIT) Project aims to address this gap, to inform future discussions around fortification of bouillon cubes and related products. Objective: This study aims to assess the impacts of household use of multiple micronutrient-fortified bouillon cubes (containing iodine in addition to vitamin A, folic acid, vitamin B12, iron, and zinc), compared to control bouillon cubes fortified with iodine only, on: 1. Micronutrient status among women 15-49 years of age and children 2-5 years of age after 9 months of intervention 2. Hemoglobin concentrations among women 15-49 years of age and children 2-5 years of age after 9 months of intervention 3. Breast milk micronutrient concentrations among lactating women 4-18 months postpartum after 3 months of intervention Methods: This randomized, controlled doubly-masked trial will be conducted in the Kumbungu and Tolon districts in the Northern Region of Ghana, where prior data indicate that deficiencies in the selected nutrients are common. Potential participants will be: 1) non-pregnant non-lactating women of reproductive age (15 - 49 years old), 2) children 2-5 years of age, and 3) non-pregnant lactating women 4-18 months postpartum. Eligible participants will be randomly assigned to receive household rations of one of two types of bouillon cubes: 1. a multiple micronutrient-fortified bouillon cube containing vitamin A, folic acid, vitamin B12, iron, zinc, and iodine, or 2. a control cube containing iodine only Each participant's household will receive a specific amount of bouillon cube every 2 weeks, and households will be advised to prepare their meals as usual, using the study-provided cubes. The trial duration will be 9 months (38 weeks) for non-pregnant, non-lactating women and children 2-5 years of age, and 3 months (12 weeks) for lactating women. The primary outcomes will be changes from baseline to endline in concentrations of haemoglobin and biomarkers of micronutrient status. Secondary outcomes will include change in prevalence of anaemia and micronutrient deficiency; dietary intake of bouillon and micronutrients; inflammation, malaria, and morbidity symptoms; and children's anthropometric measures and child development.

NCT ID: NCT04983667 Terminated - Clinical trials for Autism Spectrum Disorder

Zinc-AA Supplementation During Pregnancy & Lactation to Assess Effects on ASD Prevalence in Offspring

Start date: May 27, 2021
Phase: N/A
Study type: Interventional

Autism and associated entities, grouped under the Autism Spectrum Disorders (ASD) is the fastest growing intellectual disability in the world, statistics signal for a 1 to 3% prevalence on infants. The cause is unknown, although some data suggest that zinc deficiency during pregnancy may have an important role in its presentation. This study seeks to supplement the nutrition of randomly selected prospective and actually pregnant women with a zinc-Amino-acid complex (Zn-AA), during pregnancy and early lactation, and compare the rate of ASD in their offspring with the rate in a similar and also randomly selected cohort of non supplemented women, to assess if Zn-AA supplementation during pregnancy has any effect on this outcome
