Since the appearance of high-efficiency anti-retrovirals (HAARTs) in the treatment of Human Immunodeficiency Virus (HIV), several studies have shown an increase in the prevalence of hypothyroidism (frank, rough or low hypothyroidism T4) in cohorts of HIV-infected adults and children. More specifically, rough hypothyroidism (increased TSH and normal thyroid peripheral hormones) have a prevalence of about 3-12% in HIV-treated patients, which is higher than the general population of about 4.3%. The etiology of frustrated hypothyroidism remains debated in the literature; Effects of antiretroviral therapy (ARV) such as Stavudine®, the effect of dyslipidemia, the effect of HIV infection itself, in proportion to severity (expressed as low CD4 cell count) and AIDS stage. Thyroid dysfunction does not appear to be of autoimmune origin, as anti-peroxidase antibodies are rarely present in HIV-infected patients, unlike the general population.
