Primary lupus-associated protein-losing enteropathy.

A 79-year-old native American female with a history of diabetes mellitus, but no history of hepatic or renal disease, presented with anasarca and hypoalbuminemia. Laboratory tests for fecal alpha 1-antitrypsin and an indium III-labeled plasma transferrin nuclear scan revealed a protein-losing enteropathy. A serological test was positive for antinuclear antibody in a titer of 1:1250 with a homogeneous pattern. This finding combined with low normal serum complement levels suggested the diagnosis of systemic lupus erythematosus (SLE). This case is unusual in that protein-losing enteropathy was the only presenting symptoms. The late onset of this disease is also unusual.

Reversible pulmonary hypertension in neonatal Graves disease.

Neonatal thyrotoxicosis may occur by transplacental transfer of thyroid stimulating immunoglobins from the mother. Although the clinical manifestations may vary in the new-born period, hyperthyroidism has been associated with several cardiac complications including supraventricular tachycardia, cardiomyopathy and congestive cardiac failure. We report the case of a nine day old baby who presented with severe pulmonary hypertension in association with congestive cardiac failure secondary to neonatal thyrotoxicosis. Treatment of the heart failure and restoration of the thyroid function resulted in complete regression of the pulmonary hypertension. The recognition and reversibility of pulmonary hypertension in neonatal Graves disease has not been previously described.
