The endocrine abnormalities associated with acquired immunodeficiency syndrome (AIDS) are reviewed. These include adrenal insufficiency, hyporeninemic hypoaldosteronism, panhypopituitarism, hypogonadism, and alterations in thyroid function tests. AIDS-related infections or neoplasms may lead to hypercalcemia, whereas malabsorption may cause hypocalcemia. The possibility that AIDS-associated cachexia and hypertriglyceridemia may be caused by cachectin (tumor necrosis factor) is discussed, along with possible therapy for cachexia with megestrol acetate. Ketoconazole, sulfonamides, and pentamidine have specific, potentially deleterious metabolic effects when used in AIDS patients. Because treatment of endocrinological abnormalities of AIDS is often effective, improved diagnosis and appropriate therapy of these abnormalities will result in improved quality of life and, possibly, longer survival of patients with AIDS.

The effects of endocrine disease on bone mass continue to attract attention. Investigations include the effects on the skeleton of thyroid disease, primary hyperparathyroidism, and their treatment. The effect of growth hormone replacement in adults with panhypopituitarism has also been investigated; children with treated growth hormone deficiency appear to reach adulthood with low bone mass. The indications for surgery in asymptomatic primary hyperparathyroidism have recently been reviewed. The associations between autoimmune thyroid disease and connective tissue disease have been investigated. Although patients with Graves' disease are frequently positive for antinuclear antibodies, there appears to be no increased risk of systemic autoimmune disease. The possible pathogenesis of diabetic bone disease via calcium malabsorption, hypercalciuria, reduced bone formation, and collagen abnormalities has been reviewed. A long-term study has clarified the links among diabetic control, limited joint mobility, nephropathy, and retinopathy. The possible mechanisms by which pregnancy may induce remission in rheumatoid arthritis have been discussed.

The diagnosis of adrenal insufficiency is discussed in case of low blood pressure and digestive symptoms. Rare inaugural abdomino-crural muscle contracture can be a misleading symptom. Here we report two new cases. A 50-year-old woman presenting a leaning forward walking attitude and negligence for the past 2 months was referred to the neurologic unit. Abdomino-crural contracture, clinical hypogonadism, and hyponatremia directed towards a panhypopituitarism, which was confirmed by subsequent investigations. Pituitary MRI found an empty sella turcica. The outcome was dramatic after hormone replacement therapy, with drawing up of the trunk and re-establishment of walking after a few days. The second case is a 58-year-old man, hospitalized with altered general condition, with a weight loss of 22 kg, and anorexia in the aftermath of a comminuted fracture of the right lower limb, complicated by pseudoarthrosis. There was amyotrophy on the extremities with intense cruralgia. The patient had an antalgic attitude in the flexion affecting his rehabilitation. During 1 year, the symptoms were mimicking psychiatric disorders, malabsorption, or cancer before the final diagnosis of central hypocorticism with normal MRI was established. The evolution was remarkable after a few days of therapy with hydrocortisone, where the myalgia disappeared, the patient quickly gained weight, and the disappearance of the retractions allowed rehabilitation. These two observations emphasize the delayed diagnosis of adrenal insufficiency in the case of abdomino-crural-related symptoms and the presence of misleading neurological symptoms. The mechanisms of this syndrome remain unknown.
