About this study

Official title: Studio Clinico Randomizzato in Doppio Cieco, Controllato Verso Placebo, a Gruppi Paralleli, Sull'efficacia Clinica Di Un Prodotto a Base Di Probiotici Nel Migliorare I Comuni Sintomi Da Raffreddamento E La Risposta Immunitaria in Adulti Sani - ImmunoCold 2021

The study is a double-blind randomized clinical trial which aims to evaluate the efficacy of a multi strain probiotic in human adults in controlling and improving cold symptoms and inflammatory response

Read the detailed description

Adult subjects (age 18-44) with a history of upper airways infection, will be assigned to placebo or probiotic groups and take either placebo or probiotic dietary intervention for 12 weeks. After that, a 6 weeks follow-up. The answers at: Common Cold Questionnarie (CCQ), Wisconsin Upper Respiratory Symptoms Survey-21 (WURSS-21) and quality of life score (SF-36) will be compared in the two groups. In addition, serological markers (blood count, lymphocyte subpopulation (B, T, T4, T8, NK), IFN-γ and IL-10 levels) will be evaluated over a 18 week period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cold symptoms evaluation

    Cold symptoms will be evaluated before and after treatment through Common Cold Questionnaire(CCQ). Highest score: 27, Lowest 0. Higher scores indicate worst symptoms

    Measured: 18 weeks

Secondary outcomes (3)
  1. Change of Wisconsin Upper Respiratory Symptoms Survey (WURSS-21)

    Changes of WURSS-21 questionnaire will be assessed before and after treatment. Highest score: 147, Lowest 0. Higher scores indicate worst symptoms

    Measured: 18 weeks

  2. Change of Short Form Health Survey 36 (SF-36)

    Higher score on Short Form Health Survey 36 (SF-36) questionnaire will be considered as an improvement of life quality. Highest score: 147, Lowest 0. Higher scores indicate better perception of one's health

    Measured: 18 weeks

  3. Inflammatory status

    A reduction of inflammatory markers (INF-y, IL-10, and lymphocite B, T, T4, T8, NK) will be considered as an improvement of inflammatory status

    Measured: 18 weeks

What are the possible benefits and risks?

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

Are results available for this study?

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.

Cold symptoms evaluation (time frame: 18 weeks). 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.
