We report another case of this association.Our patient, whose mother was diabetic, had received full immunization and had normal psychomotor development. At 3 years of age, she presented with thrombocytopenia; at 9, 12, and 15 years of age, she developed pneumonia; and at 15 years of age, purulent peritonitis and pericardial effusion occurred. Three years later, she developed pneumonia again, and at age 19 she experienced repeated chest pain that prompted referral to our hospital.Ischemic heart disease, pulmonary hypertension, cystic fibrosis, and tuberculosis were excluded. ...References1.
