Clinical and immunological evaluation of patients with mild IgG1 deficiency.

Serum IgG subclass concentrations were determined in patients visiting, the pulmonology out-patient clinic with chronic respiratory tract problems. A total of 24 patients with a serum IgG1 concentration < 4.9 g/l (i.e. below the reference range) and normal values for IgG2, IgM and IgA were included. Patients with a selective IgG1 deficiency were vaccinated with a 23-valent pneumococcal polysaccharide vaccine. There were nine patients with a poor antibody response to pneumococcal capsular polysaccharide antigens. Responsiveness to protein antigens was intact in all patients. Patients with pneumonia showed a significantly lower anti-polysaccharide response in the IgG2 subclass than patients without pneumonia. Patients with recurrent sinusitis showed a significantly lower response in the IgA isotype after vaccination with pneumococcal polysaccharide vaccine compared with non-sinusitis patients. It can be concluded that patients with recurrent sinopulmonary infections and a mild IgG1 subclass deficiency have an impaired IgG1 anti-polysaccharide response, which can extend to decreased IgG2 and IgA anti-polysaccharide responses.

Measuring the quality of life before and after bilateral lung transplantation in patients with cystic fibrosis.

Lung transplantation is an important topic today in healthcare policy because the technique is new and costly. One of the important issues in the evaluation of lung transplantation is quality of life. The quality of life after lung transplantation must be relatively high compared with other forms of medical care to legitimize the high costs of transplantation. Quantifying the quality of life after lung transplantation and other medical therapies is possible with general measurements of quality of life. In a pilot study of six patients with cystic fibrosis, the quality of life, both before and after lung transplantation, was measured by the following five instruments: (1) standard gamble, (2) time trade-off, (3) the Karnofsky performance status, (4) the EuroQol visual analog scale, and (5) the Nottingham health profile. This pilot study demonstrates that the introduced methodology is feasible. The preliminary results suggest that the improvement in quality of life for patients with cystic fibrosis after bilateral lung transplantation is comparable to the improvement in quality of life after heart transplantation.

[Minocycline as a cause of acute eosinophilic pneumonia]. / Minocycline als oorzaak van acute eosinofiele pneumonie.

A rare side effect of minocycline is acute eosinophilic pneumonia. In the literature only ten cases have been reported. We report two cases of minocycline which induced (eosinophilic) alveolitis. A high fever, dry cough, dyspnoea and fatigue are the main features of the clinical picture. Peripheral blood eosinophilia and elevated total IgE content were seen in one patient. Bronchoalveolar lavage in this patient revealed eosinophilia. Transbronchial lung biopsies showed infiltration with eosinophilic granulocytes in both patients. Airway macrophages contained brown-black pigment granules. In the acute stage an important decrease in diffusion capacity was observed. The pulmonary and systemic symptoms promptly cleared up after discontinuation of minocycline. Provocation with minocycline was positive, because both patients noticed the same symptoms within one day.
