Serum IgG antibodies to Pseudomonas aeruginosa cell surface antigens were determined by enzyme linked immunosorbent assay. Titres in patients without cystic fibrosis were low (140-235). Those in patients with cystic fibrosis who were chronically infected by P. aeruginosa were very high (1100-20,500), while patients who grew the organism intermittently had(More)
Immunoglobulin G (IgG) antibodies to Pseudomonas aeruginosa surface antigens in serum were estimated by enzyme-linked immunosorbent assay for all patients from whom P. aeruginosa was isolated for the first time during a study period of 3 years (33 patients). The titer of IgG antibodies was greater than control values at or up to 24 months before the first(More)
Serum IgA antibodies to Pseudomonas aeruginosa cell surface antigens were estimated by ELISA. Titres in patients with and without cystic fibrosis and with no pseudomonal infection were low (less than 105 to less than 261). Titres in patients with cystic fibrosis who were chronically infected with P aeruginosa were very high (1200-163,000), and patients who(More)
Pseudomonas cepacia infection has become increasingly common among patients with cystic fibrosis in North America. In a large cystic fibrosis centre in the United Kingdom 11 cases have been identified during the last six years, with a maximum prevalence of 7% in 1988. Three patients have died, two of whom deteriorated rapidly shortly after acquisition of(More)
Neutrophil function studies have been carried out in a series of 44 patients with primary myelodysplastic syndromes (MDS). In vitro tests of phagocytosis and killing of Candida guilliermondii and Staphylococcus aureus identified 13 patients with abnormal neutrophil function at presentation and a further 10 who developed abnormalities during the course of(More)
In a prospective, randomized trial in 100 febrile neutropenic children, aztreonam plus flucloxacillin was compared with piperacillin plus gentamicin. At the 72 h clinical assessment there was no statistically significant difference between the two groups. However, in microbiologically documented infections there was a higher response rate in the(More)
Pus from 84 patients with subcutaneous abscesses was examined for aerobic and anaerobic bacteria: organisms were recovered from 70 (83.3 per cent). In 13 no organisms were seen in the Gram-stained smears and the cultures showed no bacterial growth. Staphylococcus aureus was the most prevalent organism (n = 44), isolated in 43 in pure culture, in marked(More)
