About this study

Official title: A Randomised Controlled Trial of Iodine-containing Micronutrient Powders Versus Oral Iodised Oil to Prevent Iodine Deficiency in Weaning Infants

In this study, two intervention strategies to address iodine deficiency and prevent iodine deficiency disorders in breast-fed weaning infants will be evaluated in a mild to moderate iodine-deficient population in Zamboanga del Norte, Philippines, Southeast Asia.

Read the detailed description

Universal salt iodization (USI) is the most effective means to ensure optimal population iodine status and prevent iodine deficiency. In countries where USI is well implemented it is generally assumed that iodine requirements of infants are covered through breast milk. As infants wean from breast milk, at the age of 4-6 months, iodized salt programs likely contribute little to their iodine intakes. Home-prepared complementary foods have low native iodine content and pediatric guidelines recommend no extra salt be given to infants during the first year making the dietary sources of iodine limited. Weaning infants may therefore be particularly vulnerable to iodine deficiency and its effects.

Iodine is an essential micronutrient and an integral component of the thyroid hormones, needed for normal growth and development, particularly of the brain. Thyroid hormones play a critical role for development of the central nervous system from early fetal life until well after birth. Thyroid hormone insufficiency during postnatal development is associated with sensorimotor and language deficits and hypothyroidism in infancy is associated with poorer language, memory skills, fine motor, auditory processing, attention and executive processing.

In iodine deficient areas where iodized salt coverage is poor, WHO, UNICEF and the International Council for the Control of Iodine Deficiency Disorders (ICCIDD) recommend infants between 7 and 24 months be given a daily dose of 90 µg iodine (potassium iodate) or an annual dose of 200 mg iodine (iodised oil). The scientific evidence for this recommendation is weak, however, and it is uncertain under what conditions the two prevention strategies may be applied and which of the two is best when.

The objective of this study is to evaluate the efficacy and safety of the two recommended intervention strategies in iodine-deficient weaning infants. The need for high-quality controlled studies to better understand the potential contribution and synergy of alternative strategies to help achieve optimal iodine nutrition in different population groups and settings has recently been defined as a major research priority.

Following a cross-sectional, pilot study, we will conduct a randomized controlled trial to assess the efficacy of two daily doses of iodine as potassium iodate (90 µg, 100% of the WHO recommended dose, and 45 µg, 50% of the WHO recommended dose) and the annual dose of 200 mg iodine in iodised oil, via a randomized, controlled trial in weaning infants of lactating mothers living in an area affected by mild to moderate iodine deficiency in Zamboanga del Norte, Philippines, Southeast Asia.

We will compare the efficacy of each of the iodine doses against each other, and against micro-nutrients given alone, estimate the optimal level of iodine for inclusion in MNPs, and report on the safety of these interventions in weaning infants.

This study will provide important guidance to public health experts, governments and international organisations to ensure normal infant thyroid function and growth and development.

Questions about this trial

What is this clinical trial studying?

A study testing MNP90, MNP45 and IODISED OIL in people with Iodine Deficiency Disorders, run by Swiss Federal Institute of Technology.

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 7 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: withdrawn, as of the sponsor's last update on 30 Jan 2017. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Infant urinary iodine concentration (UIC) (time frame: 24 weeks). The study lists 2 primary outcomes in all. 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 30 Jan 2017.
