Abstract

To identify potential risk factors for the development of subclinical hypothyroidism following long-term valproic acid monotherapy in children with epilepsy. Serum levels of thyroid-stimulating hormone, free thyroxine, free triiodothyronine, thyreoglobulin antibodies, and thyroid peroxidase antibodies were determined in 41 patients and in 41 sex- and age-matched healthy children. Mean valproic acid treatment duration was 2.80±1.96 years. The valproic acid group had higher serum thyroid-stimulating hormone (p<0.001) and free triiodothyronine (p<0.05) levels compared to the control group. Serum thyroid-stimulating hormone and free triiodothyronine were above the upper limit for healthy controls in 34% and 32% of patients, respectively, and no clinical features of thyroid dysfunction were observed. Duration of valproic acid monotherapy for less than four years was a risk factor for elevated thyroid-stimulating hormone levels. One third of children with normal range serum valproic acid levels may have elevated serum thyroid-stimulating hormone and free triiodothyronine levels, especially in the first four years of treatment.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 April 2016.
All research outputs
#19,973,506
of 24,542,484 outputs
Outputs from Epileptic Disorders
#480
of 722 outputs
Outputs of similar age
#276,111
of 358,919 outputs
Outputs of similar age from Epileptic Disorders
#11
of 15 outputs
Altmetric has tracked 24,542,484 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 722 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 358,919 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
