title: Addition of macrolide in treating adult hospitalized community-acquired pneumonia.
abstract: OBJECTIVE
  Current clinical practice guidelines, including those in south Asia, recommend the addition of a macrolide to a broad-spectrum antibiotic for the treatment of severe hospitalized community-acquired pneumonia (CAP). The aim of this study was to observe the influence of macrolide addition on clinical outcomes of hospitalized adult patients with CAP.
  
  
  METHODS
  Over a 16-month period between 2002 and 2004, 141 eligible patients were prospectively recruited from an urban-based teaching hospital in Malaysia.
  
  
  RESULTS
  Of the 141 patients, 63 (44.7%) patients (age (standard deviation (SD)) 56 (20.0) years; 50.8% male) received a macrolide-containing antibiotic regimen, while 78 (55.3%; age (SD) 57 (20.2) years; 52.6% male) were on a single broad-spectrum antibiotic only. In total, 39 (27.7%) and 102 (72.3%) patients had severe and 'non-severe' pneumonia, respectively. Irrespective of whether they had severe or non-severe pneumonia, there were no significant differences in mortality (non-severe pneumonia, 6.5% vs. 5.4%, P = 0.804; severe pneumonia, 17.6% vs. 18.2%, P = 0.966), need of ventilation (non-severe pneumonia, 8.7% vs. 3.6%, P = 0.274; severe pneumonia, 23.5% vs. 13.6%, P = 0.425) or median length of hospital stay (non-severe pneumonia, 5.5 vs. 5 days, P = 0.954; severe pneumonia, 7 vs. 6 days, P = 0.401) between the two treatment regimens.
  
  
  CONCLUSIONS
  This observational, non-randomized study suggests that addition of a macrolide may not convey any extra clinical benefits in adult hospitalized patients with CAP.
