    Abstract:
    BACKGROUND: Pneumonia is a common respiratory disease, which has a mortality rate of approximately 14% worldwide. The management of pneumonia is based on the patient and microbiological profile existing in the community. There is a paucity of data regarding patient demographics and the microbiological profile for pneumonia in the United Arab Emirates (UAE). METHODS: We conducted a retrospective analysis of in-patients with pneumonia in the UAE. Epidemiological, clinical and microbiological data was collected from patients over the age of 16 years admitted to a single university hospital with a diagnosis of pneumonia between the years 1997 and 2002. Patients were categorised as having community acquired (CAP) or hospital acquired pneumonia (HAP). RESULTS: Among the 361 patients, 186 were females and 175 males. The mean age (+/- SEM) of the males was 59 +/- 1.6 years and of the females, 56.9 +/- 1.5 years. The annual hospital admission rate for pneumonia increased from 410 per million population in 1997 to 760 in 2002. The pneumonia was community acquired in 289 (80%) and hospital acquired in 72 (20%). Hospitalisation for CAP showed a significant seasonal variation with peak admission rates in March and April and the nadir in August and September. The overall mortality rate was 13%, and was significantly higher for HAP (24%) than for CAP (10%, p < 0.01). The common microorganisms isolated from sputum culture in CAP were Haemophilus influenzae (18.6%) and Streptococcus pneumoniae (10%). The common pathogen in HAP was Pseudomonas aeruginosa in (50%). 4 out of 17 (23%) H. influenzae isolates were resistant to amoxicillin and 2 of 9 S. pneumoniae isolates (22%) were resistant to penicillin. CONCLUSIONS: The hospitalisation rate for CAP has increased over the years and showed a clear seasonal trend in the UAE. H. influenzae was the most common organism among patients with CAP and P. aeruginosa in HAP. The mortality rate for HAP was significantly higher than for CAP. The drug resistance pattern was similar to reports from centres elsewhere in South East Asia.
