ADRENAL INSUFFICIENCY IN THE ANTIPHOSPHOLIPID ANTIBODY SYNDROME

Objective: Adrenal insufficiency (AI) is a rare complication of the antiphospholipid antibody syndrome (APS). The objective of this report is to describe a case and review the published literature to enhance recognition of this potentially fatal disorder by emphasizing its course, diagnosis, and cause. Data Sources: A bibliographic database with the indexing terms adrenal insufficiency, adrenal hemorrhage, adrenal thrombosis, APS, systemic lupus erythematosus, with the constraints of human subjects only, was used. Study Selection: All 27 reports meeting the indexing terms were selected for review. Data Extraction: The specific criteria used for data extraction articles included course of the disease, causation, clinical and laboratory diagnostic criteria, and therapeutic intervention. Data Synthesis: Our patient is a previously health woman who developed a respiratory tract infection, followed by a prolonged illness with fever, hypotension, nausea, depression, and venous thromboses. She was found to have AI and APS that was alleviated with hydrocortisone and anticoagulation. Initially, her adrenal glands were normal on CT scan but subsequently became enlarged and later atrophic. Of the 27 previous case reports, a majority had thromboses and typical clinical and laboratory manifestations of AI. Hemorrhagic infarction of the adrenal gland appears to be the mechanism for AI in the APS. IgG and IgM anticardiolipin antibodies are most commonly reported in association with AI in APS. Conclusions: The hypercoagulable state in the APS may lead to adrenal vein thrombosis and subsequently to hemorrhagic necrosis of the adrenal gland. This complication of APS is important to recognize because it may be fatal if untreated. (C) 1995 by W.B. Saunders Company
