Neonatal Thyroid Function

Objective Thyroid dysfunction is a known side effect of iodinated contrast media. There is some evidence to suggest that iodinated contrast media administered to pregnant women may cause thyroid dysfunction not only in themselves but also in their offspring. Here, we systematically evaluated literature on the use of iodinated contrast media prior to or during pregnancy on the offspring’s thyroid function. Design Systematic review of published literature. Materials and methods Relevant studies were identified by PubMed, EMBASE and The Cochrane Library up to June 5, 2020. All study designs, reporting on the foetal or neonatal thyroid function after exposure to iodinated contrast media prior to or during pregnancy, were included. We undertook random effects meta-analysis and pooled the estimates as proportions with 95% CIs. Results We identified 402 articles, of which 26 were included. Six studies reported (n = 369) on exposure to iodinated contrast media prior to pregnancy by hysterosalpingography and 20 studies (n = 670) on exposure to these media during pregnancy by amniofetography, urography or CT. There was low to high risk of bias. The proportion of (transient) neonatal thyroid dysfunction was 0.0% (95% CI: 0.0–2.9% based on 3 studies) for hysterosalpingography, 2.25% (95% CI: 0.03–6.55% based on 2 studies) for amniofetography and 0.0% (95% CI: 0.0–0.02% based on 5 studies) for CT. There was a tendency towards an increased risk of thyroid dysfunction with higher amounts of contrast used. Conclusions Exposure to iodinated contrast media prior to or during pregnancy may increase the risk of thyroid dysfunction in offspring. We recommend keeping the amount of contrast used as low as possible.

: Historically, the use of Iodinated Contrast Media (ICM) for diagnostic purposes, particularly radiography and computed tomography (CT), is well-known. Many of the ICM are included in the World Health Organization (WHO)’s List of Essential Medicines. Depending on the chemotype and the presence of ionizable functional group(s), the ICM are categorized in the ionic/nonionic monomers/dimers. The lipophilicity, aqueous solubility, viscosity and osmolality are major characteristics dictating their use for one procedure versus the other. Over last several decades, substantial advancement occurred in the design and development of novel ICM, solely to reduce their propensity to cause adverse effects. Given the nature of their acute usage, some of the agents with appreciable toxicity are still used. Understanding their chemistry aspects is crucial to appreciate, acknowledge and justify the usage of these extremely important torch-bearers of diagnostic agent’s class. The present review article presents an in-depth overview of the synthetic methods, therapeutic indications, potential adverse effects along with the commercial and environmental aspects of ICM. The safety and tolerability of these agents is a field that has gained significant importance, which is given due importance in the discussion.
