[Postpartum thyroiditis as the first clinical manifestation of autoimmune polyendocrine syndrome type 2 – case report].

Postpartum thyroiditis is a form of autoimmune thyroiditis developing during the first 12 months postpartum in 5-10% of women as a consequence of the immunologic flare following the immune suppression of pregnancy. Autoimmune polyendocrine syndromes are rarely diagnosed conditions characterized by the association of at least two organspecific autoimmune disorders, and on the basis of their clinical picture, they may be divided into four different types. The underestimation of their real frequency probable results from physicians’ inadequate knowledge of these clinical entities and sometimes their atypical clinical picture. Although autoimmune thyroid disease may be a component of both type 2 and 3 autoimmune polyendocrine syndromes, but the association between postpartum thyroiditis and autoimmune conditions of other endocrine organs has very rarely been described in literature. We report a case of a young woman, who after two subsequent pregnancies developed postpartum thyroiditis of different clinical pictures. After her second pregnancy, postpartum thyroiditis was followed by the development of autoimmune adrenal failure and premature ovarian failure, which allowed to diagnose type 2 autoimmune polyendocrine syndrome. Our case study suggests that every person with postpartum thyroiditis, particularly if this disorder is accompanied by atypical clinical manifestation, should be assessed for the possible presence of autoimmune polyendocrine syndrome.
