[Thyroid dysfunction in adults infected by human immunodeficiency virus]

Abstract

Patients infected with human immunodeficiency virus (HIV) have a higher prevalence of thyroid dysfunction when compared with the general population. The most frequently observed manifestations are euthyroid sick syndrome, Graves' disease and subclinical hypothyroidism. The relationship between the use of highly active antiretroviral therapy and the increased prevalence of thyroid dysfunction has been demonstrated in several series of patients. Grave's disease is recognized as a consequence of immune restitution syndrome. Besides, several studies have suggested an association between hypothyroidism and the use of nucleoside reverse transcriptase inhibitors, particularly stavudine and non-nucleoside reverse transcriptase inhibitors such as efavirenz. Further studies could provide additional evidence of the need for routine assessment of thyroid function in HIV-infected patients.
