Sir,
I read with interest the case report by Nayanar et al. on encephalopathy associated with autoimmune thyroid disease (ATD) in an 11-year-old girl.[1] The authors came to the diagnosis of hyperthyroid encephalopathy associated ATD based on suggestive clinical presentation and high thyroid profile with positive thyroperoxidase antibody.[1] It is obvious that ATD has been associated with a variety of connective tissue diseases, particularly systemic lupus erythematosus (SLE). Published data from India revealed protean SLE neuropsychiatric manifestations that might mimic those related to ATD.[2] The spectrum of thyroid disorders in SLE has been extensively studied in India where 36% of SLE patients had thyroid dysfunction.[3] Importantly, primary hypothyroidism was the most common dysfunction in 14%, while subclinical hypothyroidism and subclinical hyperthyroidism were seen in 12% and 2%, respectively.[3] It has been suggested that hyperthyroidism associated with SLE might be a form of presentation of thyroiditis and this association might pass unnoticed because of the similarity of some clinical manifestations. Moreover, ATD might precede or follow SLE.[4] I presume that the authors ought to consider SLE as a coexistent disease in the studied patient. Implementing appropriate tests, particularly estimating serum antinuclear antibodies, anti-dsDNA antibodies, anti-neuronal antibodies, and anti-ribosomal antibodies was envisaged. More importantly, measuring serum anti-histone antibodies ought to receive ample consideration as it has been noticed to be positive at the time of the onset of hyperthyroidism in SLE patients.[5] If that battery of tests disclosed underlying SLE, the case in question could be considered a novel case report as encephalopathy secondary to ATD-associated SLE has never been reported in the pediatric literature so far.
