Association of hemolytic anemia and early-onset pulmonary emphysema in three siblings.
Three of four siblings born to nonconsanguineous parents of Italian origin were affected with severe congenital hemolytic anemia of unknown cause, and early-onset pulmonary emphysema. Two of the three affected siblings died of septic shock after splenectomy, at the ages of 7 and 3 1/2 years, respectively. The remaining affected sibling was shown to have cutis laxa and severe pulmonary emphysema at 15 years of age. Assay of serum components indicated that alpha 1-antitrypsin and alpha 2-macroglobulin levels were normal or slightly elevated. However, there was markedly elevated activity of an elastase-like serum enzyme. The relation of the hemolytic anemia to the pulmonary findings in this family is not clear; pedigree analysis suggests a recessively inherited defect.
