About this study

Official title: Zinc Intervention in Nursing Home Elderly

Background: Zinc supplementation has the potential to improve serum zinc levels and immunity of zinc deficient nursing home elderly.

Objective: To determine the effect of zinc supplementation of 30mg/d for 3 months on serum zinc levels and T-cell mediated function of zinc deficient nursing home elderly.

Design: This is a randomized, double-blind, placebo-controlled study. Outcome measures included change in serum zinc levels and various T-cell mediated immune factors between baseline and month 3.

Hypotheses: The investigators hypothesize that zinc supplementation of 30mg/d for 3 months will improve serum zinc levels as well as various T-cell mediated immune factors in zinc deficient nursing home elderly.

Read the detailed description

Four hundred and forty-two medical charts were screened from three participating nursing homes; 53 nursing home elderly were eligible and therefore were screened for low serum zinc levels (<70µg/dL). Of these, 31 (58%) had low serum zinc levels. Participants were randomized into either the placebo (N=16) or the zinc supplemented (N=15) group. Six participants did not complete the study for various reasons including refusal to take study capsules, and advice from their physicians; one participant in the zinc group experienced nausea on two consecutive days following ingestion of the zinc capsule at the beginning of the study. A total of 25 participants completed the study with 13 and 12 receiving the placebo and zinc capsules, respectively, over a period of three months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing zinc supplementation in people with Disorder of Immune Function, run by Tufts University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 May 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

serum zinc concentration (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2015.
