Measles pneumonia: lung puncture findings in 56 cases related to chest X-ray changes and clinical features

Fifty-six African children with pneumonia following measles were investigated. Lung puncture identified bacteria by culture or countercurrent immune electrophoresis in 38% and blood culture with blood countercurrent immune electrophoresis (CIE) identified a further 17%, a bacterial diagnosis being made in a total 55%. Pneumococcus was the most common organism found, occurring in 30% of all measles pneumonias. More severe changes on chest X-ray at presentation were associated with higher rates of bacterial identification and worse outcome at 2 weeks. Chest X-ray changes were worse and bacterial identification was more common in poorly nourished children. Pneumothoraces occurred following lung puncture in 21% and surgical drainage was needed in 11%.
