The Kearns-Sayre syndrome (characterized by onset before 20, chronic
ophthalmoplegia
, pigmentary retinal degeneration and at least 1 of the following symptoms: ataxia, heart block and high protein content in the cerebrospinal fluid) is a severe variant of chronic progressive external
ophthalmoplegia
(CPEO) with frequent re-arrangements of the mitochondrial DNA (mtDNA). The aim of this paper is to report a sporadic paediatric case of Kearns-Sayre syndrome with mtDNA heteroplasmic deletion, absence of cytochrome c oxidase in many muscle fibers,
autoimmune thyroiditis
followed by depressive phobic disturbances, slowing EEG, hyperreflexia, tremor and visual hallucinations, in which the diagnosis of possible encephalopathy associated with autoimmune thyroid disease (Hashimoto encephalopathy) was made. We speculated that in this patient, predisposed by mitochondrial deletion, anti-thyroid antibodies may have interfered with mitochondrial cerebral function, causing Hashimoto encephalopathy and facilitating
ophthalmoplegia
. It seems important to study anti-thyroid antibodies in every case of Kearns-Sayre syndrome, specially if
ophthalmoplegia
is recent, even in order to the therapy.

The Kearns-Sayre syndrome, (characterized by its onset before the age of 20 years, chronic
ophthalmoplegia
, pigmentary retinal degeneration and at least one of the following symptoms: ataxia, heart block and high protein content in the cerebrospinal fluid) is a severe variant of chronic progressive external
ophthalmoplegia
with frequent rearrangements of the mitochondrial DNA (mtDNA). The aim of this paper is to report a sporadic paediatric case of Kearns-Sayre syndrome with mtDNA heteroplasmic deletion, absence of cytochrome c-oxidase in many muscle fibers,
autoimmune thyroiditis
, complete atrio-ventricular heart block in which the diagnosis of subclinical hypothyroiditis associated with autoimmune thyroid disease was made. The subclinical hypothyroidism, more severe in the presence of thyroid antibodies, may have contributed to the pathogenesis of cardiovascular disease. We hypothesized that in this patient, predisposed by mitochondrial deletion, anti-thyroid antibodies may have interfered with the mitochondrial function of conduction heart system, causing atrio-ventricular heart block. It seems important to study anti-thyroid antibodies in every case of Kearn-Sayre syndrome, specially if cardiac rhythm disturbances are present.
