An update on the endocrine manifestations of antiphospholipid syndrome

Abstract Antiphospholipid Syndrome (APS), characterized by hypercoagulability and pregnancy morbidity, poses a significant clinical challenge when involving organ systems, such as the endocrine system. APS can directly and indirectly influence the anterior and posterior lobes of the pituitary gland. The thyroid gland exhibits involvement, especially in patients with positive anticardiolipin antibodies, yet the clinical significance of the relationship with APS remains elusive. The pancreas, often overlooked, manifests in diverse ways, from pancreatitis to implications in diabetes. Adrenal insufficiency emerges as a common endocrine manifestation of APS, with adrenal hemorrhage or infarction being a presenting manifestation. Adrenal gland involvement has also been reported in the context of catastrophic APS. Pregnancy complications and infertility might be effects of APS on the female ovaries, while testicular torsion and decreased sperm concentration and total sperm count have been reported as rare effects of APS on male testes.
