in our sample&#44; contrary to the previous literature&#44; we only found hypothyroxinaemia in 3&#46;3&#37; of patients&#44; and FT4 levels had normalised in the second screening in all of them except the 3&#160;PT infants that received treatment for this condition&#46; We did not identify any cases of central hypothyroidism&#46;</p><p id="par0185" class="elsevierStylePara elsevierViewall">In our study&#44; patients with a lower BW and GA had lower levels of FT4&#44; which was consistent with the literature&#46; Birth weight was also associated with TSH values &#40;although the correlation was weak&#41; and with the history of SGA&#44; but we did not find a statistically significant association between TSH values and GA&#46; A more thorough analysis of these outcomes revealed that patients with low BWs and elevation of TSH tended to have a history of SGA and had been born at a higher GA&#44; so it is possible that these infants had a more mature hypothalamic-pituitary axis compared to infants with similar BWs and lower GAs&#46;<a class="elsevierStyleCrossRefs" href="#bib0045"><span class="elsevierStyleSup">9&#44;27</span></a></p><p id="par0190" class="elsevierStylePara elsevierViewall">We also found an association between TSH levels and the administration of dopamine&#46; Previous studies have found slightly elevated levels of TSH at 14 days post birth in neonates that had recovered from some form of severe disease in the first 2 weeks of life and that had received inotropes or steroids&#44;

In agreement with previous studies&#44; we found a higher risk of thyroid dysfunction in SGA infants compared to appropriate for GA infants&#46;</p><p id="par0200" class="elsevierStylePara elsevierViewall">The frequency of thyroid dysfunction for which treatment was indicated in extremely low birth weight patients &#40;4&#46;7&#37;

none of the patients treated with levothyroxine had abnormal results in the initial newborn screening&#44; which means that thyroid dysfunction in these patients would not have been diagnosed if it had not been for the screening protocol applied in the study&#46; In the one patient with abnormal results in the initial screening&#44; testing was delayed to 13 days post birth on account of septic shock in the first days of life that required multiple transfusions of blood products&#44; so that the week 2 blood test included in the protocol was also useful for the early identification of that anomaly&#44; and the patient was already receiving treatment by the time the abnormal results of the heel prick test became available&#46;</p><p id="par0210" class="elsevierStylePara elsevierViewall">These results corroborate the importance of performing a second screening in patients born PT or with risk factors for hypothyroidism&#44; as it allows identification of newborn infants with abnormal thyroid function that cannot be detected in the newborn screening performed at 48 to 72&#160;hours post birth due to delayed elevation of TSH&#46;<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">16&#44;17</span></a></p><p id="par0215" class="elsevierStylePara elsevierViewall">There is significant disagreement as regards the short- and long-term consequences of a relative deficiency of thyroid hormones in PT neonates&#44;

including some with long follow-ups to up to age 19 years&#44; such as the study published by Hollanders in 2015&#46;<a class="elsevierStyleCrossRefs" href="#bib0155"><span class="elsevierStyleSup">31&#8211;34</span></a></p><p id="par0225" class="elsevierStylePara elsevierViewall">On the other hand&#44; there is little evidence to date on the repercussions of replacement with levothyroxine from clinical trials or prospective studies&#46; Some authors question whether transient congenital hypothyroidism or hypothyroxinaemia of prematurity should be treated&#44; given that they tend to be mild and temporary in most patients<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6&#44;15&#44;17&#44;19</span></a> and that the literature published to date does not demonstrate a clear beneficial effect on long-term neurodevelopmental outcomes&#46; However&#44; the evidence is yet insufficient to determine whether treatment with thyroid hormones could reduce the incidence of neurologic sequelae in these patients&#46;<a class="elsevierStyleCrossRefs" href="#bib0100"><span class="elsevierStyleSup">20&#44;25&#44;35&#44;36</span></a></p><p id="par0230" class="elsevierStylePara elsevierViewall">Given the importance of adequate thyroid function in a period so critical to the development of the central nervous system&#44; it seems prudent to initiate treatment in patients with persistent hypothyroxinaemia or hyperthyrotropinaemia&#44; always after confirming test results&#44; avoiding initiation of treatment based on a single isolated value and assessing the possibility of discontinuation before age 3 years&#44; as described by some authors and recommended by the most recent guidelines&#46;<a class="elsevierStyleCrossRefs" href="#bib0090"><span class="elsevierStyleSup">18&#44;22&#44;25</span></a></p><p id="par0235" class="elsevierStylePara elsevierViewall">In our sample&#44;

we believe that measurement of thyroid hormone levels on week 2 post birth allows the identification of PT neonates at risk of thyroid abnormalities that may not be detected in the newborn screening&#46; Given the absence of universally accepted cut-off values to determine eligibility for treatment&#44; each hospital should establish them based on an assessment of outcomes in its patients&#44; and it seems prudent to initiate treatment in the case of persistent abnormalities and assess whether it can be discontinued in the first years of life&#44; except in patients with specific diseases associated with an increased risk of permanent congenital hypothyroidism&#46;</p><p id="par0245" class="elsevierStylePara elsevierViewall">Given the lack of clear evidence&#44;
