[Comparative study of Legionella pneumonia and other nosocomial-acquired pneumonia].

We studied 20 cases of legionella pneumonia and 23 cases of non-legionella pneumonia. Hyponatremia, elevated GOT and GPT were higher (P < 0.05) in legionella pneumonia group. In spite of the number of cases with diarrhoea, dyspnea, nervous symptoms, myalgia and complication were higher, especially with diarrhoea in legionella pneumonia group when compared to non-legionella pneumonia group, but the number of cases in both types of pneumonia did not show a statistically significant difference.
