Circulating thymic-hormone activity was assayed by measuring Thy 1-2 antigen induction on null lymphocytes from athymic mice incubated with human plasma or serum. Plasma from 19 normal children aged under 10 had inductive activity equivalent to 10-6-16-2 ng thymopoitin/ml. Plasma from 15 infants were severe combined immuno-deficiency, 2 of whom had(More)
The ultrastructure of the lymphocytes from three children with severe combined immunodeficiency disease (SCID) is described. Parallel tubular arrays (PTA) were found in a large percentage of circulating lymphocytes (53%, 41%, and 13%) in three SCID patients when compared to age-matched controls. The size of these inclusions was quite variable, with some(More)
A 6 1/2 year-old boy with chronic granulomatous disease (CGD) and selective IgA deficiency developed a chronic progressive pneumonia which failed to respond to several conventional combinations of antimicrobial therapy. On lung biopsy, Pseudomonas cepacia was obtained in pure culture, sensitive to chloramphenicol, tetracycline, kanamycin and nalidixic acid.(More)
Data on two patients with massive but transient protein-losing enteropathy due to gastric disease suggest that antibody-mediated allergic reactions may have been responsible for the clinical picture. The majority of patients described in the literature have had evidence of a preceding or concomitant viral infection, and three of these have had evidence of(More)
Cystic fibrosis (CF) patients with viral lower respiratory tract illnesses (LRI) had depressed levels of the third and fourth components of complement, which returned to normal after recovery. There was no clinical evidence of immune complex disease. CF patients with LRI and no virus isolates, CF patients in stable status, and non-CF patients with LRI did(More)
