The 4-hydroxy-2-alkylquinolines and their N-oxides are secondary metabolites produced by Pseudomonas aeruginosa which inhibit the growth of a number of Gram-positive organisms including Staphylococcus aureus. To facilitate the identification of these compounds in biological fluids, we have developed a rapid profiling system based on gas chromatography-electron-capture mass spectrometry of the O-bistrifluoromethylbenzoyl derivatives. Using the technique, over twenty hydroxyalkylquinolines have been identified from a culture obtained from a strain of P. aeruginosa obtained from a patient with severe bronchiectasis.
We report a patient with chronic bronchiectasis who developed systemic vasculitis. The patient was initially treated with immunosuppression; however, the addition of antibiotic therapy improved control of her vasculitis and the need for immunosuppression was reduced. Chronic bronchial suppuration may have an aetiological role in the pathogenesis of this condition.
