Abstract
Two patients are presented with Wegener's granulomatosis (WG) and lower respiratory tract infections with Staphyloccus aureus (SA). It is posulated that there is a relationship between the infection and the induction or relapse of the disease. We suggest that bronchoalveolar lavages should be performed in cases of suspected WG to identify SA-infections. The co-existence of WG and SA support the reported beneficial effects of sulfamethoxazole/trimethoprim, but needs further evaluation in patients with and without SA-infection of the airways.
