CASE REPORT TwoCases of Severe Bronchiectasis Successfully Treated with a Prolonged Course of Trimethoprim/Sulfamethoxazole Takayuki Honda, Muneharu Hayasaka*, Tsutomu Hachiya*, Keishi Kubo*, Tsutomu Katsuyama and Atsuo Nagata** Twopatients with severe bronchiectasis, one patient without other disease and the other with hyper IgE syndrome, were successfully treated with long-term therapy with low doses oftrimethoprim and sulfamethoxazole (TMP-SMZ).Recurrent respiratory infections with productive cough and high fever were resistant to various antibiotics and often disturbed the patients' activities in daily life. However, they showed marked improvement following TMP-SMZtherapy, which was started for methicillin-resistant Staphylococcus aureus (MRSA)infection. MRSAdisappeared some months later, but Pseudomonas aeruginosa appeared again in the sputum. Both patients, however, have remained free from symptomsfor over one year.

Arterial blood gas analysis on November 1 1, 1989, showed hypoxemia (PaO2, 56.8 Torr, Case Report PaCO2, 40.7 Torr; pH 7.410).

P. aeruginosa, however, appeared again in the sputumwithout exacerbation of the respiratory symp- toms. The dose of TMP-SMXwas reduced to 3 tablets/day in December 1992. ESR and CRP fell within the respective normal ranges. Arterial blood gas analysis also improved (PaO2, 77.2 Torr; PaCO2 46.2 Torr; pH 7.390). When TMP-SMZ was reduced to one tablet/day in June 1993, his temperature rose to 38.5°C with an increase of white blood cells and elevation of CRPand ESR, although a chest roentgenogram did not show new consolidation (Fig. 2). The dose of TMP-SMZwas in- creased to 2 tablets/day and his temperature was reduced. He then continued to take the same dose daily for one year, and no side effects were observed. Whenthe dose of TMP-SMZwas again reduced gradually and stopped in June 1994, he noted fever and an increase in productive cough. TMP-SMZtherapy was restarted and the symptomsdisappeared immediately. He has remainedfree from symptomson a regimenof one tablet of TMP-SMZper day without adverse reactions to date. Case 2 (Fig. 3) Figure2.

From1989, whenshe was 30 years old, she often cameto our hospital with respiratory infection and high fever. She was diagnosed as having bronchiectasis and was treated with various antibiotics. She had no history of chronic sinuitis or pulmonary tuberculo- sis. A chestroentgenogram (Fig. 3) and CT scans showed cystic lesions and bronchial thickening in the right upper lobe and bronchial thickening in both lower lobes. These respiratory symptoms often disturbed her activity in daily life and she was admitted several times over the following years. Methicillin- sensitive Staphylocossus aureus (MSSA)and P. aeruginosa were isolated from sputum. In 1991, MRSAwas first detected in sputum and TMP-SMZwas added to the other antibiotics in her treatment regimen. After initiation of TMP-SMZtreatment, the symptomsof respiratory infection were reduced. The dose of TMP-SMZwas reduced and stopped because we had no experience regarding its long-term use and the available drug information emphasized its side effects. On February 9, 1993, she again visited our hospital with fever and productive cough, Figure4.
